**Disclaimer**

This report is not a legally binding document, and is not meant to
replace the published regulation titled \"National Emission Standards
for Hazardous Air Pollutants (NESHAP): Reciprocating Internal Combustion
Engines (*Federal Register*, June 15, 2004, beginning on page 33474).
This document presents specific aspects of the regulation and may not
cover all parts of the regulation. This document is an elaboration of
the appropriate legal document, and the final authority rests solely in
the legal document.

1.  **Introduction and How to Use this Handbook**

Section 112 of the Clean Air Act (CAA) requires the U. S. Environmental
Protection Agency (EPA) to list categories of major and area sources of
Hazardous Air Pollutants (HAP) and to establish National Emission
Standards for Hazardous Air Pollutants (NESHAP) for the listed source
categories. The final stationary reciprocating internal combustion
engine (RICE) NESHAP was published on June 15, 2004 (69 FR 33474). The
rule regulates HAP emissions from specific RICE that are located at
major sources of HAP. The final rule establishes emission limitations
based on maximum achievable control technology (MACT), and is commonly
called the "RICE MACT."

The purpose of this document is to educate sources, EPA Regional Office
staff and State/local air pollution control agency personnel on the
requirements of the final RICE NESHAP. This document is divided into
five sections, including this section. Section 2 provides a step-by-step
procedure for you to determine if your engine or engines are subject to
MACT requirements. Section 3 provides a summary of when you will have to
meet these MACT requirements. Sections 4 through 9 present a summary of
the specific MACT requirements for each engine subcategory. Key
definitions are provided in Appendix A.

1.  **How Should I Use this Handbook?**

This Handbook will provide assistance to help you determine whether your
engine is subject to MACT requirements. Use the tools provided in
Section 2.0 of this Handbook, along with the final RICE MACT, to
evaluate MACT requirements for each engine at your facility.

If your engines are subject to MACT requirements, use the remaining
sections of this Handbook to become familiar with the MACT requirements
for your engines' subcategories.

Regulatory references are provided throughout the Handbook to direct the
user to the original regulatory text for each requirement. These
references are provided in brackets (e.g., \[\'63.2\] to reference 40
CFR §63.2).

2.  **How Do I Get Copies of the Final Rule or Updates?**

You can find a copy of the rule in Title 40 of the Code of Federal
Regulations (CFR) part 63, subpart ZZZZ, or in the June 15, 2004
*Federal Register*, beginning on page 33474. You may also obtain rule
updates on the Internet via EPA's Air Toxics Website at the following
address:<http://www.epa.gov/ttn/atw/rice/ricepg.html>.

2.  **Are My Engines Subject to MACT?**

The purpose of this section is to help you determine whether you have
engines at your facility that are subject to the RICE MACT (40 CFR part
63, subpart ZZZZ). Figure 1 is an applicability flow diagram that
provides a brief overview of the determination process. The following is
a detailed step-by-step process that provides guidance for making this
determination.

As you proceed through each applicability determination step below, you
will be instructed to enter your results for each engine in Table 1,
which will provide documentation of this process for your records.

Note that if you have RICE at your facility, you should keep a record of
your applicability determination for 5 years, even if you are NOT
subject to any other requirements under the IC Engine MACT.
\[\'\'63.1(b)(3) and 63.10(b)(3)\]

**[Step 1: Do you have "stationary" RICE at your
facility?]{.underline}**

The first step in the applicability determination process is to
determine whether or not you have one or more "stationary" RICE at your
facility. If you do not, your facility is not subject to the RICE MACT
and you do not need to continue with this handbook.

A stationary RICE is any internal combustion engine that (1) uses
reciprocating motion to convert heat energy into mechanical work and (2)
is not mobile \[§63.6585(a)\]. Nonroad engines are considered to be
mobile engines and therefore are not considered stationary RICE.
Specifically, your engine is NOT considered a stationary RICE if:

-   it is used to drive motor vehicles or vehicles used only for
    competition; or

-   it is in or on a piece of equipment that is self-propelled or can be
    self propelled as well as performing another function (for example,
    garden tractors, off-highway mobile cranes and bulldozers)
    \[§1068.30\]; or

-   it is in or on a piece of equipment that is intended to be propelled
    while performing its function (for example lawnmowers and string
    trimmers) \[§1068.30\]; or

-   it changes location within one year (or shorter period of time if
    the engine is at a seasonal source) \[§1068.30\].[^1]

Stationary RICE are typically used for compressor and pump drives,
electricity generation, and other industrial processes. Stationary RICE
may be fueled by gasoline, diesel fuel, natural gas, landfill gas,
digester gas, and other types of fuels.

^a^ Only include engines with site-rated horsepower greater than 500, as
instructed in step 3.

^b^ Refer to the definition for existing, new, and reconstructed
included step 4.

^c^ Use the subcategories included in step 5.

Finally, uninstalled stationary RICE that are being tested at a
stationary RICE test cell/stand are not subject to the RICE MACT
\[§63.6585\]. A stationary RICE is considered "uninstalled" if it is not
installed in or an integrated part of the final product (an example of a
final product is a power generator) \[§63.9285(b)\].

**[Step 2: Is your facility a major source for hazardous air pollutants
under the RICE MACT?]{.underline}**

The second step is to determine whether or not your facility is a major
source for HAP under the RICE MACT. If you are not a major source, you
are considered an area source and the RICE MACT does not apply to you.
If you determine that you are not subject to the RICE MACT because your
facility is not a major source for HAP emissions, you are still required
to keep records of that determination for 5 years. \[\'\'63.10(b)(3) and
63.10(b)(3)\]

You are a major source if your plant site emits or has the potential to
emit 10 tons per year (tpy) of one HAP or 25 tpy of any combination of
HAP \[§63.6585(b)\]. Most RICE or groups of RICE are not major HAP
emissions sources by themselves but are located at major HAP sites. Note
that a facility is considered "major" for HAP emissions, regardless of
the contribution from the RICE alone.

When calculating the potential to emit, include all HAP emission sources
located within the contiguous area and under common control, not just
RICE. However, the RICE MACT has special considerations for determining
major source status of oil and gas production and natural gas
transmission and storage facilities \[§63.6585(b)\].

1.  Do not add together emissions from any oil or gas exploration or
    production well (with its associated equipment[^2]) and emissions
    from any pipeline compressor station or pump station with emissions
    from other similar units, even when emission points are in a
    contiguous area or under common control.

2.  For oil and gas production facilities, do not add together emissions
    from processes, operations, or equipment that are not part of the
    same oil and gas production facility.[^3]

3.  For production field facilities[^4], only HAP emissions from glycol
    dehydration units, storage vessel with the potential for flash
    emissions, combustion turbines and reciprocating internal combustion
    engines need to be added together.

4.  Do not add together emissions from processes, operations, and
    equipment that are not part of the same natural gas transmission and
    storage facility.[^5]

To determine the potential to emit, follow these steps:

1.  Identify all sources of emissions considering the oil and natural
    gas provisions listed above, if applicable.

2.  Identify all HAP that your plant site emits.

    a.  To determine what HAP is emitted from your engines, there are
        several sources of information you may use, including test data,
        AP-42,[^6] data published by the Gas Technology Institute,[^7]
        or engineering calculations.

    b.  For other emissions sources, you may also use test data, AP-42,
        engineering calculations, or other published information. EPA
        has a website devoted to methods for identifying and estimating
        emissions: <http://www.epa.gov/ttn/chief/>.

3.  Select a method to use to determine your HAP emissions. (See Table
    2)

4.  For each HAP, determine the maximum amount that each production
    process or piece of equipment in your plant site can emit in one
    year.

    a.  The simplest way to estimate maximum emissions is to assume that
        your RICE (or other process) operates 24 hours per day, 7 days
        per week, 365 days per year without control.

    b.  However, your RICE may have certain limitations that may affect
        its emissions, such as restrictions on the hours of operation,
        the presence of a control device, or the type of fuel used. If
        these restrictions are federally enforceable,[^8] you may
        include the effect that these restrictions have on emissions in
        your potential-to-emit calculations.

    c.  The final rule has a special procedure for calculating
        potential-to-emit from oil and natural gas production facilities
        \[§63.6675\]. Potential-to-emit is typically calculated using
        the maximum natural gas or hydrocarbon liquid throughput for an
        oil and natural gas production facility. You may choose from one
        of the following methods to determine your maximum natural gas
        or hydrocarbon liquid throughput if you are an oil and natural
        gas production facility \[§63.760(a)\]:

        i.  If you can show a decline in annual natural gas or
            hydrocarbon liquid throughput (whichever is appropriate) for
            the five years prior to June 17, 1999, your maximum annual
            natural gas or hydrocarbon liquid throughput is the average
            annual natural gas or hydrocarbon liquid throughput for the
            three years prior to June 17, 1999 times 1.2.[^9]

        ii. If you cannot show a decline in annual natural gas or
            hydrocarbon liquid throughput (whichever is appropriate) for
            the five years prior to June 17, 1999, your maximum annual
            natural gas or hydrocarbon liquid throughput is the highest
            annual natural gas or hydrocarbon liquid throughput over the
            five years prior to June 17, 1999 times 1.2. [^10]

        iii. You may use your facility's design maximum natural gas or
             hydrocarbon liquid throughput to estimate potential-to-emit
             for your facility.

        iv. You must determine the maximum values for other parameters
            used to estimate potential-to-emit as the maximum for the
            same period of time you determined your maximum natural gas
            or hydrocarbon liquid throughput above. You must base these
            parameters on an annual average or the highest single
            measured value.

    d.  The final rule also has a special procedure for calculating
        potential-to-emit from natural gas transmission and storage
        facilities \[§63.6675\]. Potential-to-emit is typically
        calculated using the maximum natural gas throughput for a
        natural gas transmission and storage facility. You may choose
        from one of the following methods to determine your maximum
        natural gas throughput if you are a natural gas transmission and
        storage facility \[§63.1270(a)(1) and (2)\]:

        i.  If your facility stores natural gas, you may choose to
            calculate maximum annual natural gas throughput using the
            following equation: [^11]

> $$\text{Throughput} = \frac{8,\text{760}}{\left( \frac{1}{\text{IR}_{\text{max}}}\  + \ \frac{1}{\text{WR}_{\text{max}}} \right)}$$
>
> Where:
>
> Throughput = Maximum annual facilitywide natural gas throughput in
> cubic meters per year.
>
> IR~max~ = Maximum facility injection rate in cubic meters per hour.
>
> WR~max~ = Maximum facility withdrawal rate in cubic meters per hour.
>
> 8,760 = Maximum hours of operation per year.

ii. If your facility only transports natural gas, you may calculate
    maximum annual natural gas throughput as the highest annual natural
    gas throughput over the five years prior to June 17, 1999 times
    1.2.[^12]

iii. You may use your facility's design maximum natural gas throughput
     to estimate potential-to-emit for your facility.

iv. You must determine the maximum values for other parameters used to
    estimate potential-to-emit as the maximum for the same period of
    time you determined your maximum natural gas throughput above. You
    must base these parameters on an annual average or the highest
    single measured value.

5.  Add the maximum emissions from all production processes and
    equipment, except:

    a.  Do not add together emissions from any oil or gas exploration or
        production well (with its associated equipment) and emissions
        from any pipeline compressor station or pump station with
        emissions from other similar units, even when emission points
        are in a contiguous area or under common control.

    b.  For oil and gas production facilities, do not add together
        emissions from processes, operations, or equipment that are not
        part of the same oil and gas production facility.

    c.  For production field facilities, only HAP emissions from glycol
        dehydration units, storage vessel with the potential for flash
        emissions, combustion turbines and reciprocating internal
        combustion engines need to be added together.

    d.  Do not add together emissions from processes, operations, and
        equipment that are not part of the same natural gas transmission
        and storage facility.

**Table 2. Methods to determine your HAP emissions**

  -----------------------------------------------------------------------
  **Method**            **Instructions**

  Test Data             Conduct onsite measurements of HAP emissions.

  Material-balance      Estimate HAP emissions by comparing types and
  calculations          quantities of inputs to types and quantities of
                        outputs.

  Source specific       Formulas for HAP emissions using source-specific
  models                parameters such as types and quantities of
                        inputs, operating hours, and physical
                        characteristics of equipment.

  Emission factors      Use average HAP emission rates (provided by EPA,
                        other agencies, or equipment vendors), multiplied
                        by time or frequency of operation, to obtain
                        emissions. HAP emission factors specific to your
                        facility can be used.
  -----------------------------------------------------------------------

**[Step 3: Is the site-rated horsepower of your stationary engines
greater than 500?]{.underline}**

Now that you have determined that you have stationary engines and are a
major source of HAP, you must determine which of your stationary RICE
have a site-rated horsepower greater than 500. If you only have
stationary RICE with a site-rated horsepower less than or equal to 500
you are not subject to the RICE MACT \[§63.6590(a)\]. EPA will conduct a
future rulemaking for these engines, with proposal expected October 31,
2006 and promulgation expected December 20, 2007.

Your site-rated horsepower is the maximum manufacturer's design capacity
of your stationary RICE at engine site conditions \[§63.6675\]. For each
stationary RICE that has a site-rated horsepower greater than 500, enter
your facility-specific engine ID, manufacturer's name, model number, and
the actual site-rated horsepower in Table 1 of this section.

**[Step 4: Are your engines considered "new," "reconstructed," or
"existing" under MACT?]{.underline}**

Once you have identified all of your stationary RICE with site-rated
horsepower greater than 500 at your major source, you must determine
whether your RICE are considered new, reconstructed, or existing under
MACT.

The distinction between new and existing stationary RICE depends upon
the date that you commenced construction of your engine. Construction of
an engine is considered to have *commenced* when you have undertaken a
continuous program of construction (or reconstruction) \[§63.2\]. This
includes entering into contractual obligations to undertake and complete
a continuous program of construction (or reconstruction).

If construction commenced before December 19, 2002, the engine is
EXISTING.

If construction commenced on or after December, 19, 2002, the engine is
NEW.

Your engine is considered reconstructed if you have replaced components
such that the fixed capital cost of the new components is more than
50 percent of the cost of a comparable new engine and it is
technologically and economically feasible for the reconstructed engine
to meet the MACT standard \[§63.2\]. The MACT requirements are the same
for new and reconstructed stationary RICE. If you commenced
reconstruction on or after December 19, 2002, the engine is
RECONSTRUCTED.

**[Step 5: Under which MACT subcategory does each engine
fall?]{.underline}**

Now that you have identified which stationary RICE with site-rated
horsepower greater than 500 at your major source are new/reconstructed
or existing, you must determine the subcategory for each engine. The
RICE MACT has different requirements for each subcategory of stationary
RICE. Determine which of the following subcategories applies for each
RICE that has a site-rated horsepower greater than 500 entered in Table
1:

1.  Emergency stationary RICE

2.  Limited use stationary RICE

3.  Stationary RICE that combust landfill gas or digester gas equivalent
    to 10 percent or more of the gross heat input on an annual basis.

4.  Compression ignition (CI)

5.  Spark ignition 4-stroke rich burn (4SRB);

6.  Spark ignition 2-stroke lean burn (2SLB); and

7.  Spark ignition 4-stroke lean burn (4SLB).

Refer to the following paragraphs to determine the applicable
subcategory for each of engines listed in Table 1. Your engine should be
under ONE of these subcategories. For example, if you have a 4SRB engine
that qualifies as an "emergency stationary RICE," the engine is ONLY
under the "emergency" subcategory for the purpose of MACT requirements.

**[Step 5a. Do you have a stationary RICE with a site-rating of 500
brake horsepower or less?]{.underline}**

Under Step 3, you identified the engines that are part of this
subcategory. These engines are not subject to requirements under the
RICE MACT and none of these engines were entered into Table 1. However,
EPA will conduct a future rulemaking for these engines, with proposal
expected October 31, 2006 and promulgation expected December 20, 2007.
You are still required to keep a record of the MACT applicability
determination for these engines for 5 years. \[§§63.1(b)(3) and
63.10(b)(3)\]

**[Step 5b. Do you have an emergency stationary RICE?]{.underline}**

Emergency situations include the production of power for critical
networks or equipment when electric power from the local utility is
interrupted, as well as pumping water in the case of fire or flood
\[§63.6675\]. Stationary RICE that operate in an emergency situation are
considered emergency stationary RICE, provided the following criteria
are met:

-   emergency stationary RICE may be operated to perform maintenance
    checks and readiness testing, provided these tests are recommended
    by the manufacturer, vendor or insurance company associated with the
    engine.

-   there is no limit on the use of an emergency stationary RICE in
    emergency situations and for routine testing and maintenance, but
    testing should be minimized.

-   emergency stationary RICE may be operated in non-emergency
    situations no more than 50 hours per year.

Complete the subcategory column of Table 1 for each engine that meets
the criteria of an emergency stationary RICE.

**[Step 5c. Do you have a limited use stationary RICE?]{.underline}**

Any stationary RICE that operates less than 100 hours per year is
considered a limited use stationary RICE \[§63.6675\].

Complete the subcategory column of Table 1 for each engine that meets
the criteria of a limited use stationary RICE.

**[Step 5d. Do you have a stationary RICE that combust landfill gas or
digester gas equivalent to 10 percent or more of the gross heat input on
an annual basis?]{.underline}**

This subcategory is applicable to any of your engines that use landfill
gas or digester gas as fuel equivalent to 10 percent or more of the
annual gross heat input. Landfill gas is the gaseous by-product of the
land application of municipal refuse typically formed through the
anaerobic decomposition of waste materials and is composed primarily of
methane and CO~2~. Digester gas is the gaseous by-product of wastewater
treatment typically formed through the anaerobic decomposition of
organic waste materials and is composed primarily of methane and CO~2~.
\[§63.6675\]

To calculate the gross heat input, you must use the flow rate and
heating values of each fuel for the year. The following are heating
values of typical fuels used by stationary RICE.[^13]

  ----------------------------- -----------------------------------------
  Fuel                          Heating Values

  Natural Gas                   1,050 Btu/scf

  Diesel Fuel                   19,300 Btu/lb

  Gasoline                      20,300 Btu/lb
  ----------------------------- -----------------------------------------

Complete the subcategory column of Table 1 for each engine that meets
the criteria of a stationary RICE that combusts landfill gas or digester
gas equivalent to 10 percent of the gross heat input on an annual basis.

**[Step 5e. Do you have a spark ignition stationary RICE?]{.underline}**

You have a **spark ignition** engine if the compressed air/fuel mixture
of your engine is ignited by a timed electric spark generated by a spark
plug \[§63.6675\]. If you have a spark ignition stationary RICE, you
must determine whether you have a 4-stroke rich burn (4SRB) engine, a
2-stroke lean burn (2SLB) engine, or a 4-stroke lean burn (4SLB) engine
(Steps 5e.i through iii).

**[Step 5e.i. Do you have a spark ignition 4SRB stationary
RICE?]{.underline}**

**[Step 5e.ii. Do you have a spark ignition 2SLB stationary
RICE?]{.underline}**

> All spark ignition 2-stroke engines are considered 2SLB under the IC
> Engine MACT. A 2-stroke engine is an engine that completes the power
> cycle in a single crankshaft revolution \[§63.6675\].
>
> Complete the subcategory column of Table 1 for each engine that is a
> 2SLB engine.

**[Step 5e.iii. Do you have a spark ignition 4SLB stationary
RICE?]{.underline}**

> You have a 4SLB stationary RICE if your stationary RICE is not a rich
> burn engine and your engine completes the power cycle in two
> crankshaft revolutions, with intake and compression strokes in the
> first revolution and power and exhaust strokes in the second
> revolution \[§63.6675\].
>
> Complete the subcategory column of Table 1 for each engine that is a
> 4SLB engine.

**[Step 5f. Do you have compression ignition stationary
RICE?]{.underline}**

You have a **compression ignition** (CI) engine if a high boiling point
liquid fuel injected into the combustion chamber of your engine ignites
when the air charge has been compressed to a temperature sufficiently
high for auto-ignition. Compression engines include diesel engines,
dual-fuel engines (engines where liquid fuel, usually diesel fuel, is
used for compression ignition and a gaseous fuel, usually natural gas,
is used as the primary fuel), and engines that are not spark ignition
engines \[§63.6675\].

Complete the subcategory column of Table 1 for each engine that is a CI
stationary RICE.

**[Step 6: Which of your engines have requirements under
MACT?]{.underline}**

Using the subcategory determined in Step 5 and whether the engine is
"new," "reconstructed," or "existing," as determined in Step 4, you can
now identify the engines at your major-source facility that are subject
to MACT requirements.

The following are not subject any requirements under the NESHAP
\[§63.6590(b)(3)\]:

-   Stationary RICE being tested at a stationary RICE test cell/stand;

-   Stationary RICE with site rating of 500 brake horsepower or less;

-   Existing spark ignition 2SLB stationary RICE;

-   Existing spark ignition 4SLB stationary RICE;

-   Existing CI stationary RICE;

-   Existing stationary RICE that combust landfill or digester gas
    equivalent to 10 percent or more of the gross heat input on an
    annual basis;

-   Existing emergency stationary RICE; and

-   Existing limited use stationary RICE.

Note that you must still keep a record of the MACT applicability
determination for 5 years for these engines. \[§§63.1(b)(3) and
63.10(b)(3)\]

The following new or reconstructed engines have limited requirements
under subpart ZZZZ \[§63.6590(b)(1) and (2)\]:

-   Emergency stationary RICE \>500 HP;

-   Limited use stationary RICE \>500 HP; and

-   Stationary RICE \>500 HP that combust landfill or digester gas
    equivalent to 10 percent or more of the gross heat input on an
    annual basis.

The following have full MACT requirements, including emission
limitations, operating limitations, and requirements for performance
tests, monitoring, recordkeeping and reporting:

-   Existing, new, or reconstructed spark ignition 4SRB stationary RICE
    \>500 HP;

-   New or reconstructed spark ignition 4SLB stationary RICE \>500 HP;

-   New or reconstructed spark ignition 2SLB stationary RICE \>500 HP;

-   New or reconstructed compression ignition (CI) stationary RICE \>500
    HP.

Table 3 presents a summary of the types of requirements for each engine
subcategory. Section 3 presents a timeline of when you must meet the
requirements of MACT. Sections 4 through 8 provide a summary of the
specific requirements for each engine subcategory.

**When Do I Have to Meet the MACT Requirements?**

The following figures present the compliance timeline for your
stationary RICE. Figure 1 presents the compliance timeline for existing
4SRB stationary RICE. Figure 2 presents the timeline for new or
reconstructed 4SRB engines. Figures 3, 4, and 5 present the timelines
for new or reconstructed 2SLB, 4SLB, and CI engines, respectively. The
timeline for stationary RICE with limited requirements (i.e., emergency
engines, limited use engines, and engines that combust landfill or
digester gas equivalent to 10 percent or more of the gross heat input on
an annual basis) is presented in Figure 6.

**What are the MACT Requirements for 4-Stroke Rich Burn Engines?**

The purpose of this section is to provide a detailed summary of the MACT
requirements for 4-Stroke Rich Burn (4SRB) stationary RICE. For each
4SRB stationary RICE subject to Subpart ZZZZ, you have to comply with
the full MACT requirements, including emission limitations, operating
limitations, and requirements for performance tests, monitoring,
recordkeeping and reporting. The following sections provide a detailed
summary of these requirements.

1.  What are the Emission Limitations?

2.  What are the Emission Testing Requirements?

3.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Using NSCR?

4.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Not Using NSCR?

5.  What are the Startup, Shutdown, and Malfunction Requirements?

6.  What Records Must I Keep?

7.  What Notification and Reports Must I Submit?

If you do not have a 4SRB stationary RICE, you may skip this section.

1.  **What Are The Emission Limitations?**

For each new, reconstructed or existing spark ignition 4SRB stationary
RICE subject to Subpart ZZZZ, you must comply with ONE of the following
emission limitations at 100 percent load plus or minus 10 percent
\[Table 1a\]:

-   Reduce formaldehyde emissions by 76 percent or more (referred to as
    the formaldehyde percent reduction limit); OR

-   Limit the formaldehyde concentration in the stationary RICE exhaust
    to 350 parts per billion, by volume on a dry basis (ppbvd) at 15
    percent O~2~ (referred to as the formaldehyde concentration limit)

If you have a new or reconstructed 4SRB stationary RICE that commenced
construction or reconstruction between December 19, 2002 and June 15,
2004, you may choose to reduce formaldehyde emissions by 75 percent or
more until June 15, 2007 \[Table 1a\]. After June 15, 2007, you must
comply with ONE of the final formaldehyde emission limitations listed
above. This provision is included because the final formaldehyde percent
reduction limit (76%) is more stringent than the proposed limit (75%).

You may meet the applicable emission limitation by using non-selective
catalytic reduction (NSCR) or an alternative method of control.
Whichever method of control you choose, you will have emission testing
requirements; operating limits and parameter monitoring requirements;
startup, shutdown, and malfunction requirements; recordkeeping
requirements; and notification and reporting requirements. You will have
different operating limitations and monitoring requirements depending on
the method of control you choose. Refer to the summary of operating
parameter and monitoring requirements under section 4.3 if you are using
NSCR and section 4.4 if you are using an alternative method of control.

1.  **What Are The Emission Testing Requirements?**

You must conduct emission testing on all 4SRB engines subject to Subpart
ZZZZ to show that you are meeting ONE of the applicable emission
limitations (as discussed in Section 4.1). For MACT, emission tests are
called "performance tests." The following performance tests are required
for Subpart ZZZZ:

-   You must conduct an initial performance test for all 4SRB engines
    subject to Subpart ZZZZ (see section 4.2.2).

-   You must conduct semi-annual performance tests if your 4SRB
    stationary RICE has a brake horsepower greater than or equal to
    5,000 AND you are complying with the formaldehyde percent reduction
    limit, or if you are complying with the formaldehyde concentration
    limit (regardless of engine size) (see section 4.2.3).

-   If you are using a catalyst, such as NSCR, to comply with Subpart
    ZZZZ, you also must conduct a performance test if you change your
    catalyst (see section 4.2.4).

In all cases, the emission tests must be conducted according to the
requirements included in Subpart ZZZZ, discussed below (see Section
4.2.1).

1.  How do I conduct my performance tests?

The following provisions apply to all performance tests:

-   You must conduct the tests using the test methods and other test
    procedures included in Table 4 of Subpart ZZZZ. These provisions are
    discussed further in Sections 4.2.1.1 and 4.2.1.2 below.

-   The tests must be conducted while the engine is operating at 100
    percent load plus or minus 10 percent. \[63.6620(b)\]

-   The tests must NOT be conducted during startup, shutdown, or
    malfunction (SSM) events (see section 4.5 of this document for
    details on SSM requirements) \[\'\'63.6620(c) and 63.7(e)(1)\].

-   The tests must include at least three separate test runs, and each
    test run must last at least one hour \[63.6620(d)\].

-   Operating parameters must be measured during the performance test
    (see section 4.2.2.1 for operating parameters)

-   Determination of engine load must be documented, including the
    calculations, assumptions, and measurement devices used to measure
    or estimate the percent load. This information must be submitted in
    a written report with the performance test results (see section
    4.7.4 of this document for the information that must be included in
    this report).

-   You must record ambient temperature, pressure, and humidity for the
    percent load determination and include the data in a written report
    (see section 4.7.4 of this document for the information that must be
    included in this report).

4.2.1.1 [What performance test requirements do I have to follow if I am
complying with the formaldehyde percent reduction
limitation?]{.underline}

If you are complying with the formaldehyde percent reduction limit you
must conduct all of your performance tests using the following criteria
\[Table 4, item 2\].

1.  You must select the location of the sampling port and the number of
    traverse points using Method 1 or 1A (40 CFR part 60, appendix A).
    You must choose sampling sites that are located at the inlet and the
    outlet of the NSCR or other control device; AND

2.  You must measure the O~2~ concentration at the inlet and outlet of
    the NSCR or other control device using Method 3, 3A or 3B (40 CFR
    part 60, appendix A). You must take the measurements to determine
    the O~2~ concentration at the same time as the measurements for the
    formaldehyde concentration; AND

3.  You must measure the moisture content at the inlet and outlet of the
    NSCR or other control device using Method 4 (40 CFR part 60,
    appendix A), or Method 320 (40 CFR part 63, appendix A), or ASTM D
    6348-03. You must take the measurements to determine the moisture
    content at the same time and location as the measurements for the
    formaldehyde concentration; AND

4.  You must measure formaldehyde at the inlet and the outlet of the
    NSCR or other control device using Method 320 or 323 (40 CFR part
    60, appendix A), ASTM D6348-03, [^52] provided in ASTM D6348-03
    Annex A5 (Analyte Spiking Technique), the percent R must be
    [\>]{.underline} 70 and ­[\<]{.underline} 130. You must convert the
    formaldehyde concentration to 15% O~2~, dry basis. Results of this
    test consist of the average of the three 1-hr or longer runs.

Determine compliance with the percent reduction requirement using the

4.2.1.2 [What performance test requirements do I have to follow if I am
complying with the formaldehyde concentration limitation?]{.underline}

If you are complying with the requirement to limit the formaldehyde
concentration you must conduct your initial and all subsequent
performance tests using the following criteria \[Table 4, item 3\]:

1.  You must select the location of the sampling port and the number of
    traverse points using Method 1 or 1A (40 CFR part 60, appendix A).
    You must choose a sampling site that is located at the outlet of the
    NSCR or other control device; AND

2.  You must determine the O~2~ concentration of the 4SRB stationary
    RICE exhaust at the sampling port location using Method 3, 3A or 3B
    (40 CFR part 60, appendix A). You must take the measurements to
    determine the O~2~ concentration at the same time and location as
    the measurements for the formaldehyde concentration; AND

3.  You must measure the moisture content of the 4SRB stationary RICE
    exhaust at the sampling port location using Method 4 (40 CFR part
    60, appendix A) or Method 320 (40 CFR part 63, appendix A) or ASTM D
    6348-03. You must take measurements to determine the moisture
    content at the same time and location as the measurements for the
    formaldehyde concentration; AND

4.  You must measure formaldehyde at the exhaust of the stationary RICE
    using Method 320 or 323 (40 CFR part 60, appendix A), or ASTM
    D6348-03, [^53] provided in ASTM D6348-03 Annex A5 (Analyte Spiking
    Technique), the percent R must be [\>]{.underline} 70 and
    ­[\<]{.underline} 130. You must convert the formaldehyde
    concentration to 15% O~2~, dry basis. Results of this test consist
    of the average of the three 1-hr or longer runs.

    1.  Initial Performance Test

You must conduct an initial performance test for all 4SRB engines
subject to Subpart ZZZZ to show that you are meeting either the
formaldehyde percent reduction limit or the formaldehyde concentration
limit. The initial performance test must be conducted using the methods
and test procedures presented in Section 4.2.1.

The results of the initial performance test must show that you have
reduced formaldehyde emissions by 76 percent or more or the formaldehyde
concentration in your stationary RICE exhaust is less than 350 ppbvd at
15 percent O~2~ \[\'63.6630(a)\].

If you have a new or reconstructed 4SRB stationary RICE that commenced
construction or reconstruction between December 19, 2002 and June 15,
2004, you may choose to demonstrate compliance with the optional
emission limitation of 75 percent or more reduction of formaldehyde
during the initial performance test. In that case, you must conduct an
additional performance test by December 13, 2007 to demonstrate
compliance with ONE of the final emission limitations included in
Subpart ZZZZ. \[\'63.6610(c)\]

1.  [Measuring Operating Parameters During the Initial Performance
    Test]{.underline}

If you use NSCR to comply with MACT, you must record two operating
parameters during the initial performance test:

-   pressure drop across the NSCR catalyst (Table 5, items 4 and 6); and

-   inlet temperature to the NSCR catalyst.

If you are not using NSCR and EPA has approved your petition to
establish operating limitations, you must record parameters during the
initial performance test in accordance with EPA's approval of your
petition to establish operating limitations (Table 5, items 5 and 7).
These values will be used to establish your operating limits (see
Sections 4.3 or 4.4 of this document). Note that you should not conduct
the initial performance test until EPA acts on your petition
\[\'63.6620(f)\].

If you are not using NSCR and EPA approved your petition EPA to
establish NO operating limitations, you are not required to record
parameters during the initial performance test. Note that you should not
conduct the initial performance test until EPA acts on your petition
\[\'63.6620(f)\].

1.  [When do I have to conduct the initial performance
    test?]{.underline}

[For existing 4SRB engines:]{.underline}

You have to conduct the initial performance test on your existing 4SRB
stationary RICE no later than December 12, 2007 \[\'63.6610(a)\].

[For new or reconstructed 4SRB engines:]{.underline}

If construction/reconstruction of the new or reconstructed 4SRB
commences after June 15, 2004, you must conduct the initial compliance
test within 180 days after you start up the new or reconstructed engine
\[§63.6610(a)\].

If you have a new or reconstructed 4SRB stationary RICE that commenced
construction (or reconstruction) between December 19, 2002 and June 15,
2004, you have to conduct the initial performance test no later than
February 10, 2005 or no later than 180 days after startup of your
engine, whichever date is later \[§63.6610(b)\].

For engines that opt to comply initially with 75% reduction of
formaldehyde:

If you have chosen to reduce formaldehyde emissions by the 75-percent
emission limitation from the proposed rule \[67 FR 77830, §63.6600(a)\],
you must conduct the initial performance test by the deadlines discussed
above.

In addition, you must conduct a second performance test by December 13,
2007 to show that you are now complying with the 76-percent emission
limitation from the final rule after June 15, 2007 \[\'63.6610(c)\].

2.  [When is an initial performance test not required?]{.underline}

You do not have to perform an initial performance test if you have
conducted a performance test on your 4SRB stationary RICE that meets the
following criteria:

1.  The test was conducted using the same test methods specified in
    section 4.2.1.1 or 4.2.1.2 of this document, and you followed these
    methods correctly.

2.  The test is not older than 2 years.

3.  The test has been reviewed and accepted by EPA.

4.  No process or equipment changes have been made since the test was
    performed, or you can demonstrate that the results of the
    performance test, with or without adjustments, reliably demonstrate
    compliance despite process or equipment changes.

5.  The test was conducted at any load condition within
    ­[+]{.underline}10 percent of 100 percent load.

    1.  Semiannual Performance Tests

You must conduct semi-annual performance tests if:

-   You are complying with the formaldehyde percent reduction limit AND
    your 4SRB stationary RICE has a brake horsepower greater than or
    equal to 5,000.

-   You are complying with the formaldehyde concentration limit
    (regardless of engine size) \[\'63.6615 and Table 3\].

If you conduct two consecutive performance tests and are in compliance
with the applicable emission limitation, you may conduct the subsequent
performance tests on an annual basis. You must resume semi-annual tests
if:

-   Any subsequent performance test shows that you are not in compliance
    with your emission limit, or

-   You deviate from any of your operating limitations \[Table 3,
    footnote\].

    1.  Other Required Tests

If you are using a catalyst, such as NSCR, to comply with Subpart ZZZZ,
and you change the catalyst, you are required to conduct a performance
test to show that you are meeting the applicable emission limitation.
You must also reestablish the values of the operating parameters
measured during the initial performance test \[\'63.6640(b)\]. If you
are using NSCR to comply with MACT, you must reestablish the initial
pressure drop for the NSCR catalyst and measure the inlet temperature to
the catalyst during the catalyst-change performance test.

4.2.5 Reports and Notifications for Performance Tests

The reports and notifications required for performance tests are
presented in the table below:

  -----------------------------------------------------------------------
  **Reports and Notifications for All 
  Performance Tests**

  -----------------------------------------------------------------------

These reports and notifications are discussed further in Sections 4.6
and 4.7.

1.  **What are the Operating Limits and Parameter Monitoring
    Requirements If I am Using NSCR?**

In addition to meeting emission limitations, you must also meet certain
operating limits. The operating limits for 4SRB engines are presented in
Table 1b of Subpart ZZZZ.

It is important to note that these operating limits are enforceable
independent of the emission limits -- they are not triggers to assess
your emissions. Instead they are separate and enforceable limits.

This section presents the operating limit and parameter monitoring
requirements if you are using non-selective catalytic reduction (NSCR)
to meet the applicable formaldehyde emission limit. If you are not using
NSCR, section 4.4 presents the operating limit and parameter monitoring
requirements for other control technologies.

The operating limits and parameter monitoring requirements are the same
for both the 76-percent formaldehyde percent reduction and the 360-ppbvd
formaldehyde concentration requirement.

1.  Operating Limits for 4SRB Engines using NSCR to Comply with MACT

Two operating limits apply for 4SRB engines using NSCR to comply with
MACT:

-   Maintain your catalyst so that the pressure drop across the catalyst
    does not change by more than two inches of water at 100 percent load
    plus or minus 10 percent from the pressure drop across the catalyst
    measured during the initial performance test; and

-   Maintain the temperature of your engine exhaust so that the catalyst
    inlet temperature is greater than or equal to 750F and less than or
    equal to 1250F.

Note that you establish the initial pressure drop across the catalyst
during the initial performance test. The allowable range for pressure
drop is 2" WC from the initial pressure drop. Also note that if you
change your catalyst, you are required to reestablish the initial
pressure drop for the new catalyst element.

As discussed further below, to demonstrate compliance with these
operating limits, you must measure pressure drop across the catalyst
monthly, and you must continuously monitor temperature at the catalyst
inlet (i.e., the stationary RICE exhaust temperature at the catalyst
inlet).

1.  Monthly Pressure Drop Measurements

You demonstrate that you are meeting the pressure drop operating limit
by measuring the pressure drop across the NSCR once a month \[Table 6,
items 4 and 7\]. The monthly pressure drop measurements should be taken
while the engine is operating at 100% load 10%.

You are meeting the operating limit if the pressure drop measured each
month is within two inches of water of the pressure drop measured during
the performance test \[Table 1b, item 1\].

2.  Continuous Catalyst Inlet Temperature Monitoring

You are required to install and operate a Continuous Parameter
Monitoring System (CPMS) to measure NSCR inlet temperature \[Table 5,
items 4 and 6\]. You must collect the NSCR inlet temperature data and
reduce these data to 4-hour rolling averages \[Table 6, items 4 and
7\].[^54] You are meeting the NSCR inlet temperature operating limit if
the 4-hour rolling average NSCR inlet temperature is greater than or
equal to 750^o^F or less than or equal to 1,250^o^F \[Table 1b, item
1\].

3.  Continuous Parameter Monitoring System Requirements

For each stationary RICE, you are required to install a CPMS to
continuously monitor catalyst inlet temperature (Table 5, items 4 and
6). For each CPMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for your CPMS
\[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 4.5 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^55] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^56] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 4.7 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time as the
notification to conduct your performance test.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CPMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance test or performance evaluation is scheduled to
begin, or on a mutually agreed upon date. The Administrator will review
and approve the performance evaluation test plan at the same time as the
review and approval of the site-specific test plan (if review of the
site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Operating Limits and Parameter Monitoring
        Requirements If I am not Using NSCR?**

If you choose to meet the formaldehyde emission limits using a control
technique other than NSCR, you are required to petition the
Administrator for approval of operating limitations to be established
during the initial performance test. If you feel that no operating
limits are appropriate for your technology, you may also petition the
Administrator for approval of no operating limitations. Your petition
has to receive approval from the Administrator before you can conduct
your initial performance test \[\'63.6620(f)\].

1.  Petition for Approval of Operating Limitations

If you petition the Administrator for approval of operating limitations,
the petition must contain the following information \[\'63.6620(g)\]:

-   You must identify the specific parameters you propose to use as
    operating limitations;

-   You must provide a discussion of the relationship between these
    parameters and HAP emissions, identifying how HAP emissions change
    with changes in these parameters, and how limitations on these
    parameters will serve to limit HAP emissions;

-   You must provide a discussion of how you will establish the upper
    and/or lower values for these parameters which will establish the
    limits on these parameters in the operating limitations;

-   You must provide a discussion identifying the methods you will use
    to measure and the instruments you will use to monitor these
    parameters, as well as the relative accuracy and precision of these
    methods and instruments; and

-   You must provide a discussion identifying the frequency and methods
    for recalibrating the instruments you will use for monitoring these
    parameters.

    1.  Petition for Approval of No Operating Limitations

If you petition the Administrator for approval of no operating
limitations, your petition must include the following information
\[\'63.6620(h)\]:

-   You must identify the parameters associated with operation of the
    stationary RICE and the emission control device which could change
    intentionally (e.g., operator adjustment, automatic controller
    adjustment, etc.) or unintentionally (e.g., wear and tear, error,
    etc.) on a routine basis or over time;

-   You must provide a discussion of the relationship, if any, between
    changes in the parameters and changes in HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of whether establishing
    limitations on the parameters would serve to limit HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of how you could
    establish upper and/or lower values for the parameters which would
    establish limits on the parameters in operating limitations;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the methods
    you could use to measure them and the instruments you could use to
    monitor them, as well as the relative accuracy and precision of the
    methods and instruments;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the
    frequency and methods for recalibrating the instruments you could
    use to monitor them; and

```{=html}
<!-- -->
```
-   You must provide a discussion of why, from your point of view, it is
    infeasible or unreasonable to adopt the parameters as operating
    limitations.

    1.  Continuous Parameter Monitoring System Requirements

If you have petitioned the Administrator for operating limitations, for
each stationary RICE you are required to install a continuous parameter
monitoring system (CPMS) to continuously monitor your approved operating
parameters. For each CPMS, you are required to follow certain operation
and maintenance requirements; prepare a quality control program; and
conduct performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for operation
of your CPMS \[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 4.5 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^57] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^58] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 4.7 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time you
submit the notification to conduct your performance test. If you are not
conducting a performance test, the performance evaluation notification
must be submitted at least 60 days prior to the date that you are
scheduled to begin the performance evaluation.

Before conducting the performance evaluation, you may be required to
develop and submit a site-specific performance evaluation test plan to
the Administrator for approval. The following elements must be included
in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

If the Administrator requests that you submit a site-specific
performance evaluation test plan for approval, it is due at least 60
days before the performance test or performance evaluation is scheduled
to begin, or on a mutually agreed upon date. The Administrator will
review and approve the performance evaluation test plan at the same time
as the review and approval of the site-specific test plan (if review of
the site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently chooses to use the
    specified monitoring method(s) instead of an alternative.

    1.  Requirements for Approved Operating Limits

You are required to install and operate a CPMS to measure your approved
operating limit \[Table 5, items 5 and 7\]. You must collect the
parameter data you approved by the Administrator and reduce these data
to 4-hour rolling averages \[Table 6, items 5 and 8\].[^59] You are
meeting the approved operating limit if the 4-hour rolling average
parameter data is within your approved operating limitations for the
operating parameters established during the initial performance test.

1.  **What are the Startup, Shutdown, and Malfunction (SSM)
    Requirements?**

You are required to operate your NSCR or other control device as well as
any CPMS at all times, including periods of startup, shutdown, and
malfunction (SSM), in a safe manner and according to good air pollution
control practices to minimize emissions.

A startup is defined as "the setting in operation of an affected source
or portion of an affected source for any purpose." \[§63.2\]

A shutdown is defined as "the cessation of operation of an affected
source or portion of an affected source for any purpose." \[§63.2\]

A malfunction is defined as "any sudden, infrequent, and not reasonably
preventable failure of air pollution control and monitoring equipment,
process equipment, or a process to operate in a normal or usual manner
which causes, or has the potential to cause, the emission limitations in
an applicable standard to be exceeded. Failures that are caused in part
by poor maintenance or careless operation are not malfunctions."
\[§63.2\]

1.  What are my requirements during SSM events?

You are responsible for reducing emissions to the greatest extent
possible and maintain safety and good air control practices whenever
there is a period of SSM. This does not mean that you are required to
achieve the emission levels required under the RICE MACT during SSM
events if it means that you would not be operating in a safe manner and
with good air pollution practices nor are you required to make any
further efforts to reduce emissions if you are meeting the emission
levels required by the RICE MACT.

2.  Startup, Shutdown and Malfunction Plan

You are required to develop and implement a written startup, shutdown,
and malfunction (SSM) plan that describes, in detail, procedures for
operating and maintaining the each stationary RICE during periods of
SSM, and a program of corrective action for malfunctioning process and
air pollution control and monitoring equipment (i.e., NSCR or other
control device, pressure drop monitoring equipment, and CPMS). You must
develop the SSM plan by December 13, 2007 for all of your existing
stationary RICE. You must develop this plan by August 16, 2004 if
construction or reconstruction of your new or reconstructed stationary
RICE commenced on or after December 19, 2002 but before August 16, 2004.
If construction or reconstruction of your new or reconstructed
stationary RICE began after August 16, 2004, you must have your SSM plan
developed by startup \[§63.6(e)(3)(i)\].

During periods of SSM, you must operate and maintain your stationary
RICE (including each NSCR or other control device and monitoring
equipment) in accordance with the procedures specified in your SSM plan
\[§63.6(e)(3)(ii)\].

1.  [What must be included in my SSM plan?]{.underline}

EPA does not specify the required elements of a SSM plan, but the SSM
plan must address the following \[§63.6(e)(3)(i)(A) through (C)\]:

1.  Ensure that, at all times, you operate and maintain each stationary
    RICE, including your NSCR or other control device and monitoring
    equipment, in a manner which satisfies your general duty to minimize
    emissions;

2.  Ensure that you are prepared to correct malfunctions as soon as
    practicable after their occurrence in order to minimize excess
    emissions of hazardous air pollutants; and

3.  Reduce the reporting burden associated with periods of startup,
    shutdown, and malfunction (including corrective action taken to
    restore malfunctioning process and air pollution control equipment
    to its normal or usual manner of operation).

To develop your SSM plan, you may use your standard operating procedures
(SOP) manual, or an Occupational Safety and Health Administration (OSHA)
or other plan, provided the alternative plans meet the SSM plan
requirements and are made available for inspection or submitted when
requested by EPA or the delegated authority \[§63.6(e)(3)(vi)\].

1.  [When may the SSM plan be revised?]{.underline}

You may periodically revise the SSM plan for your stationary RICE as
necessary to satisfy the requirements of 40 CFR part 63 or to reflect
changes in equipment or procedures at the affected source. Unless EPA or
your permitting authority provides otherwise, you may make such
revisions to the startup, shutdown, and malfunction plan without prior
approval by EPA or the permitting authority \[§63.6(e)(3)(viii)\].
However, each revision to a SSM plan must be reported in the semiannual
compliance report (see section 4.7.5).

If the SSM plan fails to address or inadequately addresses an event that
meets the characteristics of a malfunction but was not included in the
SSM plan at the time you developed the plan, you must revise the SSM
plan within 45 days after the event to include detailed procedures for
operating and maintaining the source during similar malfunction events
and a program of corrective action for similar malfunctions of process
or air pollution control and monitoring equipment \[§63.6(e)(3)(viii)\].

In the event that you make any revision to the SSM plan which alters the
scope of the activities which are deemed to be an SSM, or otherwise
modify the applicability of any emission limit or other RICE MACT
requirement, the revised plan may not take effect until after you have
provided a written notice describing the revision to your permitting
authority \[§63.6(e)(3)(viii)\].

If EPA or the delegated authority determines that you are not operating
and maintaining your stationary RICE (including the NSCR or other
control device and monitoring equipment) in such a way that is
consistent with safety and good air pollution control practices
\[§63.6(e)(1)(i)\], EPA or the delegated authority may require you to
make changes to the SSM plan for that stationary RICE. EPA or the
delegated authority must require appropriate revisions to a SSM plan, if
EPA or the delegated authority finds that the plan \[§63.6(e)(3)(vii)\]:

-   Does not address a SSM event that has occurred;

-   Fails to provide for the operation of the stationary RICE (including
    the NSCR or other control device and monitoring equipment) during a
    SSM event in a manner consistent with the general duty to minimize
    emissions established by §63.6(e)(1)(i);

-   Does not provide adequate procedures for correcting malfunctioning
    process and/or air pollution control and monitoring equipment as
    quickly as practicable; or

-   Includes an event that does not meet the definition of startup,
    shutdown, or malfunction listed in §63.2.

The title V permit for a stationary RICE must require that you adopt a
SSM plan which conforms to part 63, and that you operate and maintain
the stationary in accordance with the procedures specified in the
current SSM plan. However, any revisions made to the SSM plan as
specified above do not constitute permit revisions under part 70 or part
71 of this chapter. Moreover, none of the procedures specified by the
SSM plan for an affected source shall be deemed to fall within the
permit shield provision in section 504(f) of the Act
\[§63.6(e)(3)(ix)\].

1.  [What are my requirements for maintaining my SSM plan?]{.underline}

You must maintain a current SSM plan and must make the plan available
upon request for inspection and copying by the EPA or delegated
authority. In addition, if you subsequently revise your SSM plan (see
section 4.5.2.2), you must keep each previous (i.e., superseded) version
of the SSM plan, and must make each such previous version available for
inspection and copying by the EPA or the delegated authority for 5 years
after revision of the plan. If at any time after adoption of an SSM plan
the stationary RICE ceases operation or is otherwise no longer subject
to the RICE MACT, you must keep a copy of the most recent plan for 5
years from the date the stationary RICE ceases operation or is no longer
subject the RICE MACT and must make the plan available upon request for
inspection and copying by EPA or the delegated authority
\[§63.6(e)(3)(v)\].

EPA or the delegated authority may at any time request in writing that
you submit a copy of any SSM plan (or a portion thereof). Upon receipt
of such a request, you must promptly submit a copy of the requested plan
(or a portion thereof) to EPA or the delegated authority. EPA or the
delegated authority must request that you submit a particular SSM plan
(or a portion thereof) whenever a member of the public submits a
specific and reasonable request to examine or to receive a copy of that
plan or portion of a plan. You may elect to submit the required copy of
any SSM plan in an electronic format. If you claim that any portion of
such a SSM plan is confidential business information entitled to
protection from disclosure under section 114(c) of the Act or 40 CFR
2.301, the material which is claimed as confidential must be clearly
designated in the submission. \[§63.6(e)(3)(v)\]

1.  How do I demonstrate I am following my SSM plan?

When you take actions during a period of SSM (including actions taken to
correct a malfunction) that are consistent with the procedures specified
in the SSM plan developed for your stationary RICE, you must do the
following \[§63.6(e)(iii)\]:

-   You must keep records for that event which demonstrate that the
    procedures specified in the plan were followed. These records may
    take the form of a "checklist," or other form of recordkeeping that
    confirms that you followed the procedures defined in your SSM plan
    for that event.

-   You must keep the following records of these events
    \[§63.10(b)(2)\]:

    -   Records of the occurrence and duration of each startup,
        shutdown, or malfunction of operation

    -   Records of the occurrence and duration of each malfunction of
        the NSCR or other control device and monitoring equipment

-   You must confirm that actions taken during the relevant reporting
    period during periods of SSM were consistent with the startup,
    shutdown and malfunction plan developed for each stationary RICE in
    the semiannual (or more frequent) startup, shutdown, and malfunction
    report required in §63.10(d)(5). Note that this information may also
    be incorporated into your semiannual compliance report (see section
    4.7.5).

If you take an action during a startup, shutdown, or malfunction
(including an action taken to correct a malfunction) that is not
consistent with the procedures specified in your stationary RICE\'s
startup, shutdown, and malfunction plan, and the stationary RICE exceeds
the applicable emission limitation, then you must record the actions
taken for that event and must report such actions within 2 working days
after commencing actions inconsistent with the plan, followed by a
letter within 7 working days after the end of the event, in accordance
with §63.10(d)(5) (unless the owner or operator makes alternative
reporting arrangements, in advance, with the Administrator)
\[§63.6(e)(3)(iv)\].

1.  **What Records Must I Keep?**

You are required to keep records of activities required to meet the
final RICE MACT. You must keep files of all information (including
reports and notifications) required under the RICE MACT in a format
suitable and readily available for "expeditious inspection and review
\[\'63.6660(a)\]." You must maintain these records for 5 years following
the date of each occurrence, measurement, maintenance, corrective
action, report, or record \[\'63.6660(b)\]. Records may be kept in hard
copy or electronic form. You may retain at least 2 years of records
on-site. You can keep records off-site for the remaining 3 years
\[\'63.6660(c)\].

1.  Recordkeeping Requirements for Notifications and Reports

You are required to keep a copy of each notification and report that you
have submitted as a part of complying with the RICE MACT, including all
documentation supporting any notification or report \[\'63.6655(a)(1)\].
You must maintain records of the following notifications and reports
(see section 4.7 of this document for details regarding these
notifications and reports):

-   Initial Notification;

-   Notifications of performance tests;

-   Site-specific test plan;

-   Notification of performance evaluation for CPMS;

-   Site-specific performance evaluation plan;

-   Any request to use an alternative monitoring procedure;

-   Any request for extension of compliance;

-   Notification that your source is subject to special compliance
    requirements;

-   Notification of compliance status, including performance test
    results and written report to document engine load conditions during
    the test;

-   Semiannual compliance reports; and

-   Startup, shutdown, and malfunction reports.

    1.  Recordkeeping Requirements for Startup, Shutdown, and
        Malfunction Events

You are required to keep records related to startup, shutdown and
malfunction (SSM) events as follows (see section 4.5 for details on SSM
events) \[\'\'63.6655(a)(2) and 63.6(e)(3)(iii) through (v):

-   When you take actions during an SSM event (including actions taken
    to correct a malfunction), that are consistent with the procedures
    specified your SSM plan, you must keep records which demonstrate
    that the procedures specified in the plan were followed. You may
    keep records in the form of a "checklist," or you may choose another
    form of recordkeeping that documents that you have followed your SSM
    plan for that event.

-   You must keep records of these SSM events, including records of the
    occurrence and duration of each startup, shutdown, or malfunction of
    operation and each malfunction of the air pollution control and
    monitoring equipment.

-   When you take actions during an SSM event that are not consistent
    with the procedures specified in the your SSM plan, and the
    stationary RICE exceeds the formaldehyde emission limitations, then
    you must record the actions taken for that event.

-   You must maintain a current SSM plan and must make the plan
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your SSM plan, you are
    required to keep a copy of each previous (i.e., superseded) version
    of the SSM plan for 5 years after each revision. Previous versions
    must be available for inspection and copying by the Administrator.

-   If at any time after adoption of a SSM plan stationary RICE ceases
    operation or is otherwise no longer subject to the RICE MACT, you
    must retain a copy of the most recent plan for 5 years from the date
    the stationary RICE ceases operation or is no longer subject to the
    RICE MACT. This plan must be available upon request for inspection
    and copying by the Administrator.

-   The Administrator may request in writing that you submit a copy of
    any SSM plan (or portion of the plan). Upon receipt of such a
    request, you must promptly submit a copy of the requested plan (or
    portion of the plan) to the Administrator. The Administrator is
    required to request that you submit a particular SSM plan (or a
    portion thereof) whenever a member of the public submits a specific
    and reasonable request to examine or to receive a copy of that plan
    or portion of a plan. You may elect to submit the required copy of
    any SSM plan to the Administrator in an electronic format. If you
    claim that any portion of such a SSM plan is confidential business
    information entitled to protection from disclosure under section
    114(c) of the Act or 40 CFR 2.301, the material which is claimed as
    confidential must be clearly designated in the submission.

    1.  Recordkeeping Requirements for Performance Tests and CPMS

You are required to keep records of all performance test results.
Performance test results may include analysis of samples, determination
of emissions, and raw data \[\'\'63.6655(b) and 63.10(b)(2)(viii)\].

For each CPMS, you are required to keep the following records
\[\'\'6655(b) and 63.10(b)(2)(vi) through (xi)\]:

-   All CPMS performance evaluations;

-   Records of each period during which the CPMS is malfunctioning or
    inoperative (including periods where the CPMS is out of control);

-   All required measurements needed to demonstrate compliance with the
    operating limitations (including, but not limited to, 15-minute
    averages of CPMS data, raw performance testing measurements, and raw
    performance evaluation measurements, that support data that you are
    required to report);

-   All measurements as may be necessary to determine the conditions of
    performance tests and performance evaluations;

-   All CPMS calibration checks;

-   All adjustments and maintenance performed on CPMS;

-   You must maintain a current performance evaluation test plan and
    quality control procedures and must make these written procedures
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your performance evaluation
    plan, you are required to keep a copy of each previous (i.e.,
    superseded) version of the plan for 5 years after each revision
    \[\'63.8(d)(3)\]. Previous versions must be available for inspection
    and copying by the Administrator. If it is relevant, you may
    incorporate these procedures as part of your SSM plan.

You are also required to keep records of the following \[§63.10(c)(1)
through (14)\]:

-   All required CPMS measurements (including monitoring data recorded
    during unavoidable CPMS breakdowns and out-of-control periods);

-   The date and time identifying each period during which the CPMS was
    inoperative except for zero (low-level) and high-level checks;

-   The date and time identifying each period during which the CPMS was
    out of control;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during startups, shutdowns, and
    malfunctions;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during periods other than
    startups, shutdowns, and malfunctions;

-   The nature and cause (if known) of any malfunction;[^60]

-   The corrective action taken or preventative measures adopted;[^61]

-   The nature of the repairs or adjustments to the CMS that was
    inoperative or out of control;[^62]

-   The total process operating time during the reporting period; and

-   All procedures that are a part of a quality control program and
    implemented for CPMS under §63.8(d).

    1.  Recordkeeping Requirements for Monitoring Data

You are required to keep records of all monitoring data you collect to
demonstrate compliance with your operating limitations \[Table 6, items
4, 5, 7, and 8\].

If you are using NSCR you must keep records of the catalyst inlet
temperature data measured by your CPMS and the monthly pressure drop
measurements. If you are not using NSCR, you are required to keep
records of the approved operating parameter.

1.  **What Notifications and Reports Must I Submit?**

For each notification and report, you send a copy to both your State Air
Pollution Control Office and your EPA Regional Office. Appendix B
contains a list of Regional EPA offices and addresses.

1.  Initial Notification

The initial notification states that your affected source is subject to
the RICE standards. If you have an existing 4SRB engine, or a new or
reconstructed stationary RICE that you startup before August 16, 2004
you are required to submit the initial notification not later than
December 13, 2004 \[\'63.6645(b)\]**.**

If you startup your new or reconstructed stationary RICE after on or
after August 16, 2004, you are required to submit your initial
notification within 120 days after your stationary RICE becomes subject
to the RICE MACT \[\'63.6645(c)\].

You are required to provide the following information in the initial
notification \[\'63.9(b)(2)\]:

1.  The name and address of the owner or operator of your facility;

2.  The address (i.e., physical location) of your facility;

3.  An identification of the relevant standard (in this case, 40 CFR
    subpart ZZZZ), that is the basis of the notification and the your
    compliance date;

4.  A brief description of the nature, size, design, and method of
    operation of the source and an identification of the types of
    emission points within the affected source subject to the relevant
    standard and types of HAP emitted; and

5.  A statement of whether your facility is a major source or an area
    source.

Appendix C contains an example initial notification form.

1.  Notification of Intent to Conduct a Performance Test

If you are required to conduct performance tests, you must submit a
notification of intent to conduct a performance test to identify the
scheduled date for the performance test. The notification must be
submitted 60 days prior to the test to both your State Air Pollution
Control Office and your EPA Regional Office \[\'\'63.6645(e) and
63.7(b)(1)\].

2.  Performance Test Report

You must submit a performance test report within 60 days after
completing the performance test \[\'63.7(g)\]. The report must include
an analysis of samples, determination of emissions, and the raw data.
The initial performance test results may be submitted with the
notification of compliance status.

3.  Notification of Compliance Status

You must submit the Notification of Compliance Status within 60 days
following the completion of the performance test \[\'63.6645(f)(2)\].
The Notification of Compliance Status certifies that your stationary
RICE is meeting the emission limitations and operating limitations;
identifies the option(s) you used to demonstrate initial compliance,
summarizes the data and calculations supporting the compliance
demonstration, and describes how you will determine continuous
compliance.

The Notification of Compliance Status must be signed by a responsible
official certifying its accuracy, attesting to whether all stationary
RICE are complying with the RICE MACT. The Notification of Compliance
Status must contain the following information \[\'63.9(h)(2)(i)\]:

-   The methods that were used to determine compliance;

-   The results of any performance tests, CPMS performance evaluations,
    and/or other monitoring procedures or methods that were conducted;

-   The methods that will be used for determining continuing compliance,
    including a description of monitoring and reporting requirements and
    test methods;

-   The formaldehyde percent reduction (percent) or the formaldehyde
    concentration in ppbvd at 15% O~2~;

-   A description of the NSCR or other air pollution control equipment
    (or method) for each stationary RICE; and

-   A statement as to whether you have complied with the RICE MACT.

A written report of the average percent load determination must be
included in the notification of compliance status. The following
information must be included in the report:

-   the engine model number;

-   the engine manufacturer;

-   the year of purchase;

-   the manufacturer's site-rated brake horsepower;

-   the ambient temperature, pressure, and humidity measured during the
    performance test; and

-   all assumptions that were made to estimate or calculate percent load
    during the performance test must be clearly explained.

If measurement devices such as flow meters, kilowatt meters, beta
analyzers, stain gauges, etc. are used, the model number of the
measurement device, and an estimate of its accuracy in percentage of
true value must be provided.

After you have been issued a title V operating permit, you must comply
with all requirements for compliance status reports contained in your
title V permit. After you have been issued a title V operating permit,
you are required to submit the notification of compliance status to the
appropriate permitting authority following completion of the compliance
demonstrations specified in the RICE MACT.

1.  Semiannual Compliance Reports

You must submit semiannual compliance reports. The first compliance
report covers the period beginning on the compliance date for your
stationary RICE and ends on June 30 or December 31, whichever is the
first date following the end of the first calendar half after the
compliance date \[\'63.6650(b)(1)\]. The first compliance report is due
on either July 31 or January 31, whichever date follows the end of the
first calendar half after the compliance date \[\'63.6650(b)(2)\].
Subsequent reports cover the reporting periods from January 1 through
June 30 or July 1 through December 31 \[\'63.6650(b)(3)\]. Each
subsequent report is due either on July 31 or January 31, whichever is
the first date following the end of the semiannual reporting period
\[\'63.6650(b)(4)\].

Instead of the schedule just discussed, you may submit the first and
subsequent compliance reports on the dates established by your
permitting authority under title V operating permit regulations. Your
facility must be subject to title V operating permit regulations under
40 CFR part 70 or 71, and your permitting authority must have
established dates for submitting semiannual reports \[\'63.6650(b)(5)\].

The semiannual compliance report must contain the following information
\[\'63.6650(c), (d), and (e)\]:

-   Company name and address.

-   Statement by a responsible official, with that official's name,
    title, and signature, certifying the accuracy of the content of the
    report.

-   Date of report and beginning and ending dates of the reporting
    period.

-   If applicable, a statement that you had a startup, shutdown, or
    malfunction during the reporting period, and actions taken during
    the SSM event were consistent with your SSM plan.

-   If applicable, the number, duration and a description of any
    instance where you had a startup, shutdown, or malfunction during
    the reporting period, and actions taken during the SSM event were
    not consistent with your SSM plan but you did not exceed your
    formaldehyde emission limits. Also include the number, duration, and
    a description of each type of malfunction that occurred during the
    reporting period and which caused or may have caused you to exceed
    your formaldehyde emission limits.

-   If you revised your SSM plan during the reporting period, you must
    include the revision.

-   If there are no deviations from any emission or operating
    limitations that apply to you, a statement that there were no
    deviations from the emission or operating limitations during the
    reporting period.

-   If there were no periods during which the CPMS was out-of-control, a
    statement that there were no periods during which the CPMS was
    out-of control during the reporting period.

-   A statement that during the reporting period there were no
    deviations from the emission limitations or operating limitations.

-   You must report each time you did not meet your emission limitation
    or operating limitation that apply to each stationary RICE. These
    instances are deviations from the emission and operating
    limitations.

-   For each deviation from an emission limitation or operating
    limitation for a stationary RICE where you are not using a CMS to
    comply with the emission or operating limitations, you must
    include: (1) The total operating time of the stationary RICE at
    which the deviation occurred during the reporting period and (2)
    Information on the number, duration, and cause of deviations
    (including unknown cause, if applicable), as applicable, and the
    corrective action taken.

-   For each deviation from an emission limitation or operating
    limitation for a stationary RICE where you are using a CMS to comply
    with the emission or operating limitations, you must include:

    -   The date and time that each malfunction started and stopped

    -   The date, time, and duration that each CMS was inoperative,
        except for zero (low-level) and high-level checks.

    -   The date, time, and duration that each CMS was out-of-control,
        including start and end dates and hours and descriptions of
        corrective actions taken.

    -   The date and time that each deviation started and stopped, and
        whether each deviation occurred during a period of malfunction
        or during another period.

    -   A summary of the total duration of the deviation during the
        reporting period, and the total duration as a percent of the
        total source operating time during that reporting period.

    -   A breakdown of the total duration of the deviations during the
        reporting period into those that are due to control equipment
        problems, process problems, other known causes, and other
        unknown causes.

    -   A summary of the total duration of CMS downtime during the
        reporting period, and the total duration of CMS downtime as a
        percent of the total operating time of the stationary RICE at
        which the CMS downtime occurred during that reporting period.

    -   An identification of each parameter and pollutant (formaldehyde)
        that was monitored at the stationary RICE.

        since the last reporting period.

        1.  Immediate Startup, Shutdown, or Malfunction Reports

A startup, shutdown, and malfunction report must be submitted
immediately if any action taken during a startup, shutdown, or
malfunction during the reporting period are not consistent with your SSM
plan \[Table 7\]. You must report actions by phone or by fax within
2 days after starting actions inconsistent with the SSM plan, followed
by letter within 7 days. The letter must include the name, title, and
signature of the responsible official who is certifying its accuracy, an
explanation of the circumstances of the event, the reasons for not
following the SSM plan, and a description of all excess emissions and/or
parameter monitoring exceedances which are believed to have occurred
\[\'63.10(d)(5)\].

**What are the MACT Requirements for 2-Stroke Lean Burn Engines?**

The purpose of this section is to provide a detailed summary of the MACT
requirements for 2-Stroke Lean Burn (2SLB) stationary RICE. Existing
2SLB stationary RICE do not have to meet any requirements under subpart
ZZZZ. For each new or reconstructed 2SLB stationary RICE subject to
Subpart ZZZZ, you have to comply with the full MACT requirements,
including emission limitations, operating limitations, and requirements
for performance tests, monitoring, recordkeeping and reporting. The
following sections provide a detailed summary of these requirements.

1.  What are the Emission Limitations?

2.  What are the Emission Testing Requirements?

3.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Using an Oxidation Catalyst?

4.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Not Using an Oxidation Catalyst?

5.  What are the Monitoring Requirements If I am using a CEMS?

6.  What are the Startup, Shutdown, and Malfunction Requirements?

7.  What Records Must I Keep?

8.  What Notification and Reports Must I Submit?

If you do not have a new or reconstructed 2SLB stationary RICE, you may
skip this section.

1.  **What Are The Emission Limitations?**

For each new or reconstructed spark ignition 2SLB stationary RICE
subject to Subpart ZZZZ, you must comply with ONE of the following
emission limitations at 100 percent load plus or minus 10 percent
\[Table 2a\]:

-   Reduce carbon monoxide (CO) emissions by 58 percent or more
    (referred to as the CO percent reduction limit); OR

-   Limit the formaldehyde concentration in the stationary RICE exhaust
    to 12 parts per million, by volume on a dry basis (ppmvd) at 15
    percent O~2~ (referred to as the formaldehyde concentration limit).

If you have a new or reconstructed 2SLB stationary RICE that commenced
construction or reconstruction between December 19, 2002 and June 15,
2004, you may choose to limit your formaldehyde emissions by to 17 ppmvd
or less June 15, 2007 \[Table 2a\]. After June 15, 2007, you must comply
with ONE of the final emission limitations listed above. This provision
is included because the final formaldehyde concentration limit
(12 ppmvd) is more stringent than the proposed limit (17 ppmvd).

You may meet the applicable emission limitation by using an oxidation
catalyst or an alternative method of control. Whichever method of
control you choose, you will have emission testing requirements;
operating limits and parameter monitoring requirements; startup,
shutdown, and malfunction requirements; recordkeeping requirements; and
notification and reporting requirements. You will have different
operating limitations and monitoring requirements depending on the
method of control you choose. Refer to the summary of operating
parameter and monitoring requirements under section 5.3 if you are using
an oxidation catalyst and section 5.4 if you are using an alternative
method of control.

1.  **What Are The Emission Testing Requirements?**

You must conduct emission testing on new and reconstructed 2SLB engines
subject to Subpart ZZZZ to show that you are meeting ONE of the
applicable emission limitations (as discussed in Section 5.1). For MACT,
emission tests are called "performance tests." The following performance
tests are required for Subpart ZZZZ:

-   You must conduct an initial performance test for new and
    reconstructed 2SLB engines subject to Subpart ZZZZ (see section
    5.2.2).

-   You must conduct semiannual performance tests if your 2SLB
    stationary RICE is not equipped with a continuous emission monitor
    (CEM) AND you are complying with the CO percent reduction limit, or
    if you are complying with the formaldehyde concentration limit (see
    section 5.2.3).

-   If you are using an oxidation catalyst, to comply with Subpart ZZZZ,
    you also must conduct a performance test if you change your catalyst
    (see section 5.2.4).

In all cases, the emission tests must be conducted according to the
requirements included in Subpart ZZZZ, discussed below (see Section
5.2.1).

If you elect to install a CEMS to continuously monitor CO and either
oxygen or CO~2~, to demonstrate compliance with the CO percent reduction
limitation, you are required to conduct an initial performance
evaluation and relative accuracy test audit (RATA). You are not required
to conduct the performance tests specified in Table 4. Specific
requirements for CEMS are presented in section 5.5.

1.  How do I conduct my performance tests?

The following provisions apply to all performance tests:

-   You must conduct the tests using the test methods and other test
    procedures included in Table 4 of Subpart ZZZZ. These provisions are
    discussed further in Sections 5.2.1.1 and 5.2.1.2 below.

-   The tests must be conducted while the engine is operating at 100
    percent load plus or minus 10 percent. \[63.6620(b)\]

-   The tests must NOT be conducted during startup, shutdown, or
    malfunction (SSM) events (see section 5.6 of this document for
    details on SSM requirements) \[\'\'63.6620(c) and 63.7(e)(1)\].

-   The tests must include at least three separate test runs, and each
    test run must last at least one hour \[63.6620(d)\].

-   Operating parameters must be measured during the performance test
    (see section 5.2.2.1 for operating parameters)

-   Determination of engine load must be documented, including the
    calculations, assumptions, and measurement devices used to measure
    or estimate the percent load. This information must be submitted in
    a written report with the performance test results (see section

    this report).

-   You must record ambient temperature, pressure, and humidity for the
    percent load determination and include the data in a written report
    (see section 5.8.4 of this document for the information that must be
    included in this report).

    1.  [What performance test requirements do I have to follow if I am
        complying with the CO percent reduction limitation?]{.underline}

If you are complying with the CO percent reduction limit, you must
conduct all of your performance tests using the following criteria
\[Table 4, item 1\].

1.  You must measure the O~2~ at the inlet and outlet of the oxidation
    catalyst or other control device with a portable CO and O~2~
    analyzer, using ASTM D6522-00[^63] (incorporated by reference,
    according to \'63.14). You must make measurements to determine O~2~
    at the same time as the measurements for CO concentration.

2.  You must measure the CO at the inlet and outlet of the oxidation
    catalyst or other control device with a portable CO and O~2~
    analyzer, using ASTM D6522-00[^64] (incorporated by reference,
    according to \'63.14). The CO concentration must be at 15% O~2~, dry
    basis

Determine compliance with the CO percent reduction requirement using the

1.  [What performance test requirements do I have to follow if I am
    complying with the formaldehyde concentration
    limitation?]{.underline}

If you are complying with the requirement to limit the formaldehyde
concentration you must conduct your initial and all subsequent
performance tests using the following criteria \[Table 4, item 3\]:

1.  You must select the location of the sampling port and the number of
    traverse points using Method 1 or 1A (40 CFR part 60, appendix A).
    You must choose a sampling site that is located at the outlet of the
    oxidation catalyst or other control device; AND

2.  You must determine the O~2~ concentration of the 2SLB stationary
    RICE exhaust at the sampling port location using Method 3, 3A or 3B
    (40 CFR part 60, appendix A). You must take the measurements to
    determine the O~2~ concentration at the same time and location as
    the measurements for the formaldehyde concentration; AND

3.  You must measure the moisture content of the 2SLB stationary RICE
    exhaust at the sampling port location using Method 4 (40 CFR part
    60, appendix A) or Method 320 (40 CFR part 63, appendix A) or ASTM D
    6348-03. You must take measurements to determine the moisture
    content at the same time and location as the measurements for the
    formaldehyde concentration; AND

4.  You must measure formaldehyde at the exhaust of the 2SLB stationary
    RICE using Method 320 or 323 (40 CFR part 60, appendix A), or ASTM
    D6348-03, [^65] provided in ASTM D6348-03 Annex A5 (Analyte Spiking
    Technique), the percent R must be [\>]{.underline} 70 and
    ­[\<]{.underline} 130. You must convert the formaldehyde
    concentration to 15% O~2~, dry basis. Results of this test consist
    of the average of the three 1-hr or longer runs.

    1.  Initial Performance Test

You must conduct an initial performance test for new or reconstructed
2SLB engines subject to Subpart ZZZZ to show that you are meeting either
the CO percent reduction limit or the formaldehyde concentration limit.
The initial performance test must be conducted using the methods and
test procedures presented in Section 5.2.1.

The results of the initial performance test must show that you have
reduced CO emissions by 58 percent or more or the formaldehyde
concentration in your stationary RICE exhaust is less than or equal to
12 ppmvd at 15 percent O~2~ \[\'63.6630(a)\].

If you have a new or reconstructed 2SLB stationary RICE that commenced
construction or reconstruction between December 19, 2002 and June 15,
2004, you may choose to demonstrate compliance with the optional
emission limitation of less than or equal to 17 ppmvd at 15 percent O~2~
during the initial performance test. In that case, you must conduct an
additional performance test by December 13, 2007 to demonstrate
compliance with ONE of the final emission limitations included in
Subpart ZZZZ. \[\'63.6610(c)\]

1.  [Measuring Operating Parameters During the Initial Performance
    Test]{.underline}

If you use an oxidation catalyst to comply with MACT, and are NOT using
a CEMS, you must record two operating parameters during the initial
performance test (Table 5, items 1 and 6):

-   pressure drop across the catalyst; and

-   inlet temperature to the catalyst.

If you are not using an oxidation catalyst and EPA has approved your
petition to establish operating limitations, you must record parameters
during the initial performance test in accordance with EPA's approval of
your petition to establish operating limitations (Table 5, items 2 and
7). These values will be used to establish your operating limits (see
Sections 5.3 or 5.4 of this document). Note that you should not conduct
the initial performance test until EPA acts on your petition
\[\'63.6620(f)\].

If you are not using an oxidation catalyst and EPA approved your
petition EPA to establish NO operating limitations, you are not required
to record parameters during the initial performance test. Note that you
should not conduct the initial performance test until EPA acts on your
petition \[\'63.6620(f)\].

1.  [When do I have to conduct the initial performance
    test?]{.underline}

If construction/reconstruction of the new or reconstructed 2SLB
stationary RICE commences after June 15, 2004, you must conduct the
initial compliance test within 180 days after you start up the new or
reconstructed engine \[§63.6610(a)\].

If you have a new or reconstructed 2SLB stationary RICE that commenced
construction (or reconstruction) between December 19, 2002 and June 15,
2004, you have to conduct the initial performance test no later than
February 10, 2005 or no later than 180 days after startup of your
engine, whichever date is later \[§63.6610(b)\].

For engines that opt to comply initially with 17 ppmvd formaldehyde
concentration limit:

If you have chosen to limit formaldehyde emissions to 17 ppmvd or less
from the proposed rule \[67 FR 77830, §63.6600(a)\], you must conduct
the initial performance test by the deadlines discussed above.

In addition, you must conduct a second performance test by December 13,
2007 to show that you are now complying with the 12 ppmvd formaldehyde
concentration limitation from the final rule after June 15, 2007
\[\'63.6610(c)\].

2.  [When is an initial performance test not required?]{.underline}

You do not have to perform an initial performance test if you have
conducted a performance test on your 2SLB stationary RICE that meets the
following criteria:

1.  The test was conducted using the same test methods specified in
    section 5.2.1.1 or 5.2.1.2 of this document, and you followed these
    methods correctly.

2.  The test is not older than 2 years.

3.  The test has been reviewed and accepted by EPA.

4.  No process or equipment changes have been made since the test was
    performed, or you can demonstrate that the results of the
    performance test, with or without adjustments, reliably demonstrate
    compliance despite process or equipment changes.

5.  The test was conducted at any load condition within
    ­[+]{.underline}10 percent of 100 percent load.

You are also not required to conduct an initial performance test if you
install a CEMS to continuously monitor CO and either O~2~ or CO~2~.
Instead, for each CEMS, you are required to conduct an initial
performance evaluation (see section 5.5 for more details regarding the
performance evaluation). You are required to conduct the initial
performance evaluation for each CEMS by February 12, 2005 or within 180
days after startup, whichever is later.

1.  Semiannual Performance Tests

You must conduct semi-annual performance tests if:

-   You are complying with the CO percent reduction limit AND your 2SLB
    stationary RICE is NOT equipped with a CEMS.

-   You are complying with the formaldehyde concentration limit
    \[\'63.6615 and Table 3\].

If you conduct two consecutive performance tests and are in compliance
with the applicable emission limitation, you may conduct the subsequent
performance tests on an annual basis. You must resume semi-annual tests
if:

-   Any subsequent performance test shows that you are not in compliance
    with your emission limit, or

-   You deviate from any of your operating limitations \[Table 3,
    footnote\].

    1.  Other Required Tests

If you are using a catalyst, such as an oxidation catalyst, to comply
with Subpart ZZZZ, and you change the catalyst, you are required to
conduct a performance test to show that you are meeting the applicable
emission limitation. You must also reestablish the values of the
operating parameters measured during the initial performance test
\[\'63.6640(b)\]. If you are using an oxidation catalyst to comply with
MACT, you must reestablish the initial pressure drop for the catalyst
and measure the inlet temperature to the catalyst during the
catalyst-change performance test.

2.  Reports and Notification for Performance Tests

The reports and notifications required for performance tests are

These reports and notifications are discussed further in Sections 5.7
and 5.8.

1.  **What Are The Operating Limits And Parameter Monitoring
    Requirements If I Am Using An Oxidation Catalyst?**

In addition to meeting emission limitations, you may also have to meet
certain operating limits. The operating limits for 2SLB engines are
presented in Table 2b of Subpart ZZZZ. If you choose to install a CEMS,
you do not have operating limits to comply with MACT. Section 5.5
presents your requirements if you choose to install a CEMS.

It is important to note that these operating limits are enforceable
independent of the emission limits -- they are not triggers to assess
your emissions. Instead they are separate and enforceable limits.

This section presents the operating limit and parameter monitoring
requirements if you are using an oxidation catalyst to meet the
applicable CO or formaldehyde emission limit. If you are not using an
oxidation catalyst, section 5.4 presents the operating limit and
parameter monitoring requirements for other control technologies.

The operating limits and parameter monitoring requirements are the same
for both the 58-percent CO percent reduction requirement and the
12-ppmvd formaldehyde concentration requirement.

1.  Operating Limits for 2SLB Engines using Oxidation Catalyst to Comply
    with MACT

Two operating limits apply for 2SLB engines using oxidation catalyst to
comply with MACT:

-   Maintain your catalyst so that the pressure drop across the catalyst
    does not change by more than two inches of water at 100 percent load
    plus or minus 10 percent from the pressure drop across the catalyst
    measured during the initial performance test; and

-   Maintain the temperature of your engine exhaust so that the catalyst
    inlet temperature is greater than or equal to 450F and less than or
    equal to 1350F.

Note that you establish the initial pressure drop across the catalyst
during the initial performance test. The allowable range for pressure
drop is 2" WC from the initial pressure drop. Also note that if you
change your catalyst, you are required to reestablish the initial
pressure drop for the new catalyst element.

As discussed further below, to demonstrate compliance with these
operating limits, you must measure pressure drop across the catalyst
monthly, and you must continuously monitor temperature at the catalyst
inlet (i.e., the stationary RICE exhaust temperature at the catalyst
inlet).

1.  Monthly Pressure Drop Measurements

You demonstrate that you are meeting the pressure drop operating limit
by measuring the pressure drop across the catalyst once a month \[Table
6, items 1 and 7\]. The monthly pressure drop measurements should be
taken while the engine is operating at 100% load 10%.

You are meeting the operating limit if the pressure drop measured each
month is within two inches of water of the pressure drop measured during
the performance test \[Table 2b, item 1\].

2.  Continuous Catalyst Inlet Temperature Monitoring

You are required to install and operate a continuous parameter
monitoring system (CPMS) to measure catalyst inlet temperature \[Table
5, items 1 and 6\]. You must collect the catalyst inlet temperature data
and reduce these data to 4-hour rolling averages \[Table 6, items 1 and
7\].[^66] You are meeting the oxidation catalyst inlet temperature
operating limit if the 4-hour rolling average oxidation catalyst inlet
temperature is greater than or equal to 450^o^F or less than or equal to
1,350^o^F \[Table 2b, item 1\].

3.  Continuous Parameter Monitoring System Requirements

For each stationary RICE, you are required to install a CPMS to
continuously monitor catalyst inlet temperature (Table 5, items 1 and
6). For each CPMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for your CPMS
\[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 5.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^67] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^68] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 5.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time as the
notification to conduct your performance test.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CPMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance test or performance evaluation is scheduled to
begin, or on a mutually agreed upon date. The Administrator will review
and approve the performance evaluation test plan at the same time as the
review and approval of the site-specific test plan (if review of the
site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Operating Limits and Parameter Monitoring
        Requirements If I am not Using Oxidation Catalyst?**

If you choose to meet the CO or formaldehyde emission limits using a
control technique other than oxidation catalyst, you are required to
petition the Administrator for approval of operating limitations to be
established during the initial performance test. If you feel that no
operating limits are appropriate for your technology, you may also
petition the Administrator for approval of no operating limitations.
Your petition has to receive approval from the Administrator before you
can conduct your initial performance test \[\'63.6620(f)\].

1.  Petition for Approval of Operating Limitations

If you petition the Administrator for approval of operating limitations,
the petition must contain the following information \[\'63.6620(g)\]:

-   You must identify the specific parameters you propose to use as
    operating limitations;

-   You must provide a discussion of the relationship between these
    parameters and HAP emissions, identifying how HAP emissions change
    with changes in these parameters, and how limitations on these
    parameters will serve to limit HAP emissions;

-   You must provide a discussion of how you will establish the upper
    and/or lower values for these parameters which will establish the
    limits on these parameters in the operating limitations;

-   You must provide a discussion identifying the methods you will use
    to measure and the instruments you will use to monitor these
    parameters, as well as the relative accuracy and precision of these
    methods and instruments; and

-   You must provide a discussion identifying the frequency and methods
    for recalibrating the instruments you will use for monitoring these
    parameters.

    1.  Petition for Approval of No Operating Limitations

If you petition the Administrator for approval of no operating
limitations, your petition must include the following information
\[\'63.6620(h)\]:

-   You must identify the parameters associated with operation of the
    stationary RICE and the emission control device which could change
    intentionally (e.g., operator adjustment, automatic controller
    adjustment, etc.) or unintentionally (e.g., wear and tear, error,
    etc.) on a routine basis or over time;

-   You must provide a discussion of the relationship, if any, between
    changes in the parameters and changes in HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of whether establishing
    limitations on the parameters would serve to limit HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of how you could
    establish upper and/or lower values for the parameters which would
    establish limits on the parameters in operating limitations;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the methods
    you could use to measure them and the instruments you could use to
    monitor them, as well as the relative accuracy and precision of the
    methods and instruments;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the
    frequency and methods for recalibrating the instruments you could
    use to monitor them; and

```{=html}
<!-- -->
```
-   You must provide a discussion of why, from your point of view, it is
    infeasible or unreasonable to adopt the parameters as operating
    limitations.

    1.  Continuous Parameter Monitoring System Requirements

If you have petitioned the Administrator for operating limitations, for
each stationary RICE you are required to install a continuous parameter
monitoring system (CPMS) to continuously monitor your approved operating
parameters. For each CPMS, you are required to follow certain operation
and maintenance requirements; prepare a quality control program; and
conduct performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for operation
of your CPMS \[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 5.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^69] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^70] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 5.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time you
submit the notification to conduct your performance test. If you are not
conducting a performance test, the performance evaluation notification
must be submitted at least 60 days prior to the date that you are
scheduled to begin the performance evaluation.

Before conducting the performance evaluation, you may be required to
develop and submit a site-specific performance evaluation test plan to
the Administrator for approval. The following elements must be included
in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

If the Administrator requests that you submit a site-specific
performance evaluation test plan for approval, it is due at least 60
days before the performance test or performance evaluation is scheduled
to begin, or on a mutually agreed upon date. The Administrator will
review and approve the performance evaluation test plan at the same time
as the review and approval of the site-specific test plan (if review of
the site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently chooses to use the
    specified monitoring method(s) instead of an alternative.

    1.  Requirements for Approved Operating Limits

You are required to install and operate a CPMS to measure your approved
operating limit \[Table 5, items 2 and 7\]. You must collect the
parameter data you approved by the Administrator and reduce these data
to 4-hour rolling averages \[Table 6, items 2 and 8\].[^71] You are
meeting the approved operating limit if the 4-hour rolling average
parameter data is within your approved operating limitations for the
operating parameters established during the initial performance test.

1.  **What are the Monitoring Requirements If I am using a CEMS?**

If you are complying with the CO percent reduction emission limitation,
you have the option of installing a CEMS to demonstrate that you are
reducing CO by 58 percent or more. You may choose this option for any
control technique. You must install a CEMS to continuously monitor CO
and either oxygen or CO~2~ at both the inlet and outlet of the control
device according to the following \[§63.6625(a)\]:

-   You must install, operate and maintain each CEMS as specified in
    performance specifications (PS) 3 and 4A of 40 CFR part 60, appendix
    B.

-   You must conduct an initial performance evaluation and an annual
    relative accuracy test audit (RATA) according to \'63.8 and PS 3 and
    4 (40 CFR part 60, appendix B).

-   You must conduct daily and periodic data quality checks specified in
    40 CFR part 60, appendix F, procedure 1.

-   You must install the CEMS such that a minimum of one cycle of
    operation (sampling, analyzing, and data recording) is completed for
    each successive 15-minute period. There must be two data points,
    with each representing a different 15-minute period, to have a valid
    hour of data.

-   You must reduce the CEMS data to 1-hour averages computed from four
    or more data points equally spaced over each 1-hour period, except
    during periods when calibration, quality assurance, or maintenance
    activities are being performed. During these periods, an hourly
    average is considered valid if you have at least two data points,
    each representing a 15-minute period. NOTE: You may also use an
    arithmetic or integrated 1-hour average of CEMS data.

-   You must also keep records of the reduced data in parts per million
    at 15 percent oxygen or the equivalent CO~2~ concentration.

    1.  Initial Performance Evaluation Requirements

> For each CEMS, you must conduct an initial performance evaluation and
> an initial RATA using the procedures specified in §63.8 and PS 3 (for
> oxygen or CO~2~) and 4A (for CO) of 40 CFR part 60, appendix B. You

> 4. The initial performance evaluation must be conducted by February
> 12, 2005 or within 180 days after startup of your new or reconstructed
> stationary RICE, whichever date is later.

Once the performance evaluation has been completed you must calculate
the average CO percent reduction. This calculation is based on the first
four hours of monitoring data collected once the CEMS has been
successfully validated \[Table 5, item 3.a.iii\].

Determine compliance with the CO percent reduction requirement using the
following set of equations \[\'63.6620(e)\]:

2.  Additional Requirements

You are required to conduct annual RATA of each CEMS using PS 3 (for
oxygen or CO~2~) and PS 4A (for CO) \[40 CFR part 60, appendix B\], as
well as the daily and periodic data quality checks specified in 40 CFR
part 60, appendix F, procedure 1.

You must collect monitoring data (see section 5.5.3 for specific
monitoring installation, operation, and maintenance requirements) and
reduce the measurements to one-hour averages and calculate the percent
reduction of CO emissions using the formulas presented in section 5.5.1.
You must collect the one-hour average CO percent reduction data and
reduce these data to 4-hour rolling averages \[Table 6, item 3\].[^72]
You are meeting the CO percent reduction emission limit if the 4-hour
rolling average CO percent reduction is greater than or equal to 58
percent.

3.  Continuous Emission Monitoring System Requirements

For each CEMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CEMS]{.underline}

There are several operation and maintenance requirements for your CEMS
\[§63.8(c)\]:

-   You must operate the CEMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CEMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CEMS (see section 5.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CEMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CEMS operational and have the data
    verified either prior to or during the initial performance
    evaluation (you verify the operational status of your CEMS by, at a
    minimum, completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CEMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   Each CEMS must complete a minimum of one cycle of operation (i.e.,
    sampling, analyzing, and data recording) for each successive
    15-minute period;

-   You must check the zero (low-level) and high-level calibration
    drifts of each CEMS installed according to PS 3 (for oxygen or
    CO~2~) or PS 4A (for CO) at least once daily according to your
    performance evaluation plan (see section 5.5.1.3). You must adjust
    the zero (low-level) and high-level calibration drifts, at a
    minimum, whenever the 24-hour zero (low-level) drift exceeds two
    times the limits specified in the PS. The system must allow the
    amount of excess zero (low-level) and high-level drift measured at
    the 24-hour interval checks to be recorded and quantified whenever
    specified.

-   If you have a CEMS that is out of control, [^73] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CEMS is out of control
    in data averages or calculations.

-   If you have a CEMS that is out of control,[^74] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 5.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CEMS \[§63.8(d)\]. The program must contain a written protocol that
describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CEMS;

-   Determination and adjustment of the calibration drift of the CEMS;

-   Preventive maintenance of the CEMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CEMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CEMS
\[§63.8(e)\]. You must conduct this performance evaluation by February
12, 2005 or within 180 days after startup, whichever is later. You are
required to notify the Administrator in writing of the date that you are
going to conduct your performance evaluation at least 60 days before the
performance evaluation is scheduled to begin.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CEMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance evaluation is scheduled to begin, or on a
mutually agreed upon date. The Administrator will review and approve the
performance evaluation test plan. The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Startup, Shutdown, and Malfunction (SSM)
        Requirements?**

You are required to operate your oxidation catalyst or other control
device as well as any CPMS or CEMS at all times, including periods of
startup, shutdown, and malfunction (SSM), in a safe manner and according
to good air pollution control practices to minimize emissions.

A startup is defined as "the setting in operation of an affected source
or portion of an affected source for any purpose." \[§63.2\]

A shutdown is defined as "the cessation of operation of an affected
source or portion of an affected source for any purpose." \[§63.2\]

A malfunction is defined as "any sudden, infrequent, and not reasonably
preventable failure of air pollution control and monitoring equipment,
process equipment, or a process to operate in a normal or usual manner
which causes, or has the potential to cause, the emission limitations in
an applicable standard to be exceeded. Failures that are caused in part
by poor maintenance or careless operation are not malfunctions."
\[§63.2\]

1.  What are my requirements during SSM events?

You are responsible for reducing emissions to the greatest extent
possible and maintain safety and good air control practices whenever
there is a period of SSM. This does not mean that you are required to
achieve the emission levels required under the RICE MACT during SSM
events if it means that you would not be operating in a safe manner and
with good air pollution practices nor are you required to make any
further efforts to reduce emissions if you are meeting the emission
levels required by the RICE MACT.

2.  Startup, Shutdown and Malfunction Plan

You are required to develop and implement a written startup, shutdown,
and malfunction (SSM) plan that describes, in detail, procedures for
operating and maintaining the each stationary RICE during periods of
SSM, and a program of corrective action for malfunctioning process and
air pollution control and monitoring equipment (i.e., oxidation catalyst
or other control device, pressure drop monitoring equipment, and CPMS or
CEMS). You must develop this plan by August 16, 2004 if construction or
reconstruction of your new or reconstructed stationary RICE commenced on
or after December 19, 2002 but before August 16, 2004. If construction
or reconstruction of your new or reconstructed stationary RICE began
after August 16, 2004, you must have your SSM plan developed by startup
\[§63.6(e)(3)(i)\].

During periods of SSM, you must operate and maintain your stationary
RICE (including each oxidation catalyst or other control device and
monitoring equipment) in accordance with the procedures specified in
your SSM plan \[§63.6(e)(3)(ii)\].

1.  [What must be included in my SSM plan?]{.underline}

EPA does not specify the required elements of a SSM plan, but the SSM
plan must address the following \[§63.6(e)(3)(i)(A) through (C)\]:

1.  Ensure that, at all times, you operate and maintain each stationary
    RICE, including your oxidation catalyst or other control device and
    monitoring equipment, in a manner which satisfies your general duty
    to minimize emissions;

2.  Ensure that you are prepared to correct malfunctions as soon as
    practicable after their occurrence in order to minimize excess
    emissions of hazardous air pollutants; and

3.  Reduce the reporting burden associated with periods of startup,
    shutdown, and malfunction (including corrective action taken to
    restore malfunctioning process and air pollution control equipment
    to its normal or usual manner of operation).

To develop your SSM plan, you may use your standard operating procedures
(SOP) manual, or an Occupational Safety and Health Administration (OSHA)
or other plan, provided the alternative plans meet the SSM plan
requirements and are made available for inspection or submitted when
requested by EPA or the delegated authority \[§63.6(e)(3)(vi)\].

1.  [When may the SSM plan be revised?]{.underline}

You may periodically revise the SSM plan for your stationary RICE as
necessary to satisfy the requirements of 40 CFR part 63 or to reflect
changes in equipment or procedures at the affected source. Unless EPA or
your permitting authority provides otherwise, you may make such
revisions to the startup, shutdown, and malfunction plan without prior
approval by EPA or the permitting authority \[§63.6(e)(3)(viii)\].
However, each revision to a SSM plan must be reported in the semiannual
compliance report (see section 5.8.6).

If the SSM plan fails to address or inadequately addresses an event that
meets the characteristics of a malfunction but was not included in the
SSM plan at the time you developed the plan, you must revise the SSM
plan within 45 days after the event to include detailed procedures for
operating and maintaining the source during similar malfunction events
and a program of corrective action for similar malfunctions of process
or air pollution control and monitoring equipment \[§63.6(e)(3)(viii)\].

In the event that you make any revision to the SSM plan which alters the
scope of the activities which are deemed to be an SSM, or otherwise
modify the applicability of any emission limit or other RICE MACT
requirement, the revised plan may not take effect until after you have
provided a written notice describing the revision to your permitting
authority \[§63.6(e)(3)(viii)\].

If EPA or the delegated authority determines that you are not operating
and maintaining your stationary RICE (including the oxidation catalyst
or other control device and monitoring equipment) in such a way that is
consistent with safety and good air pollution control practices
\[§63.6(e)(1)(i)\], EPA or the delegated authority may require you to
make changes to the SSM plan for that stationary RICE. EPA or the
delegated authority must require appropriate revisions to a SSM plan, if
EPA or the delegated authority finds that the plan \[§63.6(e)(3)(vii)\]:

-   Does not address a SSM event that has occurred;

-   Fails to provide for the operation of the stationary RICE (including
    the oxidation catalyst or other control device and monitoring
    equipment) during a SSM event in a manner consistent with the
    general duty to minimize emissions established by §63.6(e)(1)(i);

-   Does not provide adequate procedures for correcting malfunctioning
    process and/or air pollution control and monitoring equipment as
    quickly as practicable; or

-   Includes an event that does not meet the definition of startup,
    shutdown, or malfunction listed in §63.2.

The title V permit for a stationary RICE must require that you adopt a
SSM plan which conforms to part 63, and that you operate and maintain
the stationary in accordance with the procedures specified in the
current SSM plan. However, any revisions made to the SSM plan as
specified above do not constitute permit revisions under part 70 or part
71 of this chapter. Moreover, none of the procedures specified by the
SSM plan for an affected source shall be deemed to fall within the
permit shield provision in section 504(f) of the Act
\[§63.6(e)(3)(ix)\].

1.  [What are my requirements for maintaining my SSM plan?]{.underline}

You must maintain a current SSM plan and must make the plan available
upon request for inspection and copying by the EPA or delegated
authority. In addition, if you subsequently revise your SSM plan (see
section 5.6.2.2), you must keep each previous (i.e., superseded) version
of the SSM plan, and must make each such previous version available for
inspection and copying by the EPA or the delegated authority for 5 years
after revision of the plan. If at any time after adoption of an SSM plan
the stationary RICE ceases operation or is otherwise no longer subject
to the RICE MACT, you must keep a copy of the most recent plan for 5
years from the date the stationary RICE ceases operation or is no longer
subject the RICE MACT and must make the plan available upon request for
inspection and copying by EPA or the delegated authority
\[§63.6(e)(3)(v)\].

EPA or the delegated authority may at any time request in writing that
you submit a copy of any SSM plan (or a portion thereof). Upon receipt
of such a request, you must promptly submit a copy of the requested plan
(or a portion thereof) to EPA or the delegated authority. EPA or the
delegated authority must request that you submit a particular SSM plan
(or a portion thereof) whenever a member of the public submits a
specific and reasonable request to examine or to receive a copy of that
plan or portion of a plan. You may elect to submit the required copy of
any SSM plan in an electronic format. If you claim that any portion of
such a SSM plan is confidential business information entitled to
protection from disclosure under section 114(c) of the Act or 40 CFR
2.301, the material which is claimed as confidential must be clearly
designated in the submission. \[§63.6(e)(3)(v)\]

1.  How do I demonstrate I am following my SSM plan?

When you take actions during a period of SSM (including actions taken to
correct a malfunction) that are consistent with the procedures specified
in the SSM plan developed for your stationary RICE, you must do the
following \[§63.6(e)(iii)\]:

-   You must keep records for that event which demonstrate that the
    procedures specified in the plan were followed. These records may
    take the form of a "checklist," or other form of recordkeeping that
    confirms that you followed the procedures defined in your SSM plan
    for that event.

-   You must keep the following records of these events
    \[§63.10(b)(2)\]:

    -   Records of the occurrence and duration of each startup,
        shutdown, or malfunction of operation

    -   Records of the occurrence and duration of each malfunction of
        the OXIDATION CATALYST or other control device and monitoring
        equipment

-   You must confirm that actions taken during the relevant reporting
    period during periods of SSM were consistent with the startup,
    shutdown and malfunction plan developed for each stationary RICE in
    the semiannual (or more frequent) startup, shutdown, and malfunction
    report required in §63.10(d)(5). Note that this information may also
    be incorporated into your semiannual compliance report (see section
    5.8.6).

If you take an action during a startup, shutdown, or malfunction
(including an action taken to correct a malfunction) that is not
consistent with the procedures specified in your stationary RICE\'s
startup, shutdown, and malfunction plan, and the stationary RICE exceeds
the applicable emission limitation, then you must record the actions
taken for that event and must report such actions within 2 working days
after commencing actions inconsistent with the plan, followed by a
letter within 7 working days after the end of the event, in accordance
with §63.10(d)(5) (unless the owner or operator makes alternative
reporting arrangements, in advance, with the Administrator)
\[§63.6(e)(3)(iv)\].

1.  **What Records Must I Keep?**

You are required to keep records of activities required to meet the
final RICE MACT. You must keep files of all information (including
reports and notifications) required under the RICE MACT in a format
suitable and readily available for "expeditious inspection and review
\[\'63.6660(a)\]." You must maintain these records for 5 years following
the date of each occurrence, measurement, maintenance, corrective
action, report, or record \[\'63.6660(b)\]. Records may be kept in hard
copy or electronic form. You may retain at least 2 years of records
on-site. You can keep records off-site for the remaining 3 years
\[\'63.6660(c)\].

1.  Recordkeeping Requirements for Notifications and Reports

You are required to keep a copy of each notification and report that you
have submitted as a part of complying with the RICE MACT, including all
documentation supporting any notification or report \[\'63.6655(a)(1)\].
You must maintain records of the following notifications and reports
(see section 5.8 of this document for details regarding these
notifications and reports):

-   Initial Notification;

-   Notifications of performance tests;

-   Site-specific test plan;

-   Notification of performance evaluation for continuous monitoring
    systems (CMS), including both CPMS and CEMS;

-   Site-specific performance evaluation plan(s);

-   Any request to use an alternative monitoring procedure;

-   Any request for extension of compliance;

-   Notification that your source is subject to special compliance
    requirements;

-   Notification of compliance status, including performance test
    results and written report to document engine load conditions during
    the test;

-   Semiannual compliance reports; and

-   Startup, shutdown, and malfunction reports.

    1.  Recordkeeping Requirements for Startup, Shutdown, and
        Malfunction Events

You are required to keep records related to startup, shutdown and
malfunction (SSM) events as follows (see section 5.6 for details on SSM
events) \[\'\'63.6655(a)(2) and 63.6(e)(3)(iii) through (v):

-   When you take actions during an SSM event (including actions taken
    to correct a malfunction), that are consistent with the procedures
    specified your SSM plan, you must keep records which demonstrate
    that the procedures specified in the plan were followed. You may
    keep records in the form of a "checklist," or you may choose another
    form of recordkeeping that documents that you have followed your SSM
    plan for that event.

-   You must keep records of these SSM events, including records of the
    occurrence and duration of each startup, shutdown, or malfunction of
    operation and each malfunction of the air pollution control and
    monitoring equipment.

-   When you take actions during an SSM event that are not consistent
    with the procedures specified in the your SSM plan, and the
    stationary RICE exceeds the formaldehyde emission limitations, then
    you must record the actions taken for that event.

-   You must maintain a current SSM plan and must make the plan
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your SSM plan, you are
    required to keep a copy of each previous (i.e., superseded) version
    of the SSM plan for 5 years after each revision. Previous versions
    must be available for inspection and copying by the Administrator.

-   If at any time after adoption of a SSM plan stationary RICE ceases
    operation or is otherwise no longer subject to the RICE MACT, you
    must retain a copy of the most recent plan for 5 years from the date
    the stationary RICE ceases operation or is no longer subject to the
    RICE MACT. This plan must be available upon request for inspection
    and copying by the Administrator.

-   The Administrator may request in writing that you submit a copy of
    any SSM plan (or portion of the plan). Upon receipt of such a
    request, you must promptly submit a copy of the requested plan (or
    portion of the plan) to the Administrator. The Administrator is
    required to request that you submit a particular SSM plan (or a
    portion thereof) whenever a member of the public submits a specific
    and reasonable request to examine or to receive a copy of that plan
    or portion of a plan. You may elect to submit the required copy of
    any SSM plan to the Administrator in an electronic format. If you
    claim that any portion of such a SSM plan is confidential business
    information entitled to protection from disclosure under section
    114(c) of the Act or 40 CFR 2.301, the material which is claimed as
    confidential must be clearly designated in the submission.

    1.  Recordkeeping Requirements for Performance Tests and CMS

You are required to keep records of all performance test and performance
evaluation results. Performance test results may include analysis of
samples, determination of emissions, and raw data \[\'\'63.6655(b) and
63.10(b)(2)(viii)\].

For each CMS (this includes CPMS and CEMS), you are required to keep the
following records \[\'\'63.6655(b) and 63.10(b)(2)(vi) through (xi)\]:

-   All CMS performance evaluations;

-   Records of each period during which the CMS is malfunctioning or
    inoperative (including periods where the CMS is out of control);

-   All required measurements needed to demonstrate compliance with the
    operating limitations or the CO percent reduction emission
    limitation (including, but not limited to, 15-minute averages of
    CPMS data, raw performance testing measurements, and raw performance
    evaluation measurements, that support data that you are required to
    report);

    -   For each CEMS that is automated[^75] and where the calculated
        data averages do not exclude periods of CEMS breakdowns or
        malfunction, rather than maintain a file of all CEMS subhourly
        measurements, you must retain the most recent consecutive three
        averaging periods of subhourly measurements and a file that
        contains a hard copy of the data acquisition system algorithm
        used to reduce the measured data into the reportable form of the
        standard.

    -   For each CEMS where measured data is manually reduced to the
        form of the emission limit, and where calculated data averages
        do not exclude periods of CEMS breakdowns or malfunctions,
        rather than maintain a file of all CEMS subhourly measurements,
        you must retain all subhourly measurements for the most recent
        reporting period. You must retain the subhourly measurements for
        120 days from the date of the most recent semiannual compliance
        report submitted to EPA.

    -   EPA or the delegated authority MAY require you to maintain all
        subhourly records if it is determined that these records are
        required to more accurately assess the compliance status of your
        stationary RICE. You will be notified of this requirement

-   All measurements as may be necessary to determine the conditions of
    performance tests and performance evaluations;

-   All CMS calibration checks;

-   All adjustments and maintenance performed on CMS;

-   You must maintain a current performance evaluation test plan and
    quality control procedures and must make these written procedures
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your performance evaluation
    plan, you are required to keep a copy of each previous (i.e.,
    superseded) version of the plan for 5 years after each revision
    \[\'63.8(d)(3)\]. Previous versions must be available for inspection
    and copying by the Administrator. If it is relevant, you may
    incorporate these procedures as part of your SSM plan.

You are also required to keep records of the following \[§63.10(c)(1)
through (14)\]:

-   All required CMS measurements (including monitoring data recorded
    during unavoidable CMS breakdowns and out-of-control periods);

-   The date and time identifying each period during which the CMS was
    inoperative except for zero (low-level) and high-level checks;

-   The date and time identifying each period during which the CMS was
    out of control;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during startups, shutdowns, and
    malfunctions;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during periods other than
    startups, shutdowns, and malfunctions;

-   The nature and cause (if known) of any malfunction;[^76]

-   The corrective action taken or preventative measures adopted;[^77]

-   The nature of the repairs or adjustments to the CMS that was
    inoperative or out of control;[^78]

-   The total process operating time during the reporting period; and

-   All procedures that are a part of a quality control program and
    implemented for CMS under §63.8(d).

    1.  Recordkeeping Requirements for Monitoring Data

You are required to keep records of all monitoring data you collect to
demonstrate compliance with your operating limitations \[Table 6, items
1, 2, 7, and 8\] or emission limitation \[Table 6, item 3\].

If you are using an oxidation catalyst you must keep records of the
catalyst inlet temperature data measured by your CPMS and the monthly
pressure drop measurements. If you are not using an oxidation, you are
required to keep records of the approved operating parameter. If you are
using a CEMS you are required to keep records of CO and oxygen or CO~2~
data measured by your CEMS.

1.  **What Notifications and Reports Must I Submit?**

For each notification and report, you send a copy to both your State Air
Pollution Control Office and your EPA Regional Office. Appendix B
contains a list of Regional EPA offices and addresses.

1.  Initial Notification

The initial notification states that your affected source is subject to
the RICE standards. If you have a new or reconstructed 2SLB engine that
you startup before August 16, 2004 you are required to submit the
initial notification no later than December 13, 2004
\[\'63.6645(b)\]**.**

If you startup your new or reconstructed stationary RICE on or after
August 16, 2004, you are required to submit your initial notification
within 120 days after your stationary RICE becomes subject to the RICE
MACT \[\'63.6645(c)\].

You are required to provide the following information in the initial
notification \[\'63.9(b)(2)\]:

1.  The name and address of the owner or operator of your facility;

    source.

Appendix C contains an example initial notification form.

1.  Notification of Intent to Conduct a Performance Test

If you are required to conduct performance tests, you must submit a
notification of intent to conduct a performance test to identify the
scheduled date for the performance test. The notification must be
submitted 60 days prior to the test to both your State Air Pollution
Control Office and your EPA Regional Office \[\'\'63.6645(e) and
63.7(b)(1)\].

2.  Notification of Intent to Conduct a Performance Evaluation

If you are using a CEMS, you must submit a notification of intent to
conduct a performance evaluation to identify the scheduled date for the
performance evaluation. The notification must be submitted 60 days prior
to the test to both your State Air Pollution Control Office and your EPA
Regional Office \[\'63.8(e)(2)\].

3.  Performance Test Report

You must submit a performance test report within 60 days after
completing the performance test \[\'63.7(g)\]. The report must include
an analysis of samples, determination of emissions, and the raw data.
The initial performance test results may be submitted with the
notification of compliance status.

4.  Notification of Compliance Status

If you have chosen to install a CEMS to continuously monitor CO and
oxygen or CO2 to comply with the CO percent reduction emission
limitation, you must submit your Notification of Compliance Status
within 30 days following the completion of your performance evaluation
\[§63.6645(f)(1)\].

For all other 2SLB stationary RICE for which you do not install a CEMS,
you must submit the Notification of Compliance Status within 60 days
following the completion of the performance test \[\'63.6645(f)(2)\].

The Notification of Compliance Status certifies that your stationary
RICE is meeting the emission limitations and operating limitations;
identifies the option(s) you used to demonstrate initial compliance,
summarizes the data and calculations supporting the compliance
demonstration, and describes how you will determine continuous
compliance.

The Notification of Compliance Status must be signed by a responsible
official certifying its accuracy, attesting to whether all stationary
RICE are complying with the RICE MACT. The Notification of Compliance
Status must contain the following information \[\'63.9(h)(2)(i)\]:

-   The methods that were used to determine compliance;

-   The results of any performance tests, CMS performance evaluations,
    and/or other monitoring procedures or methods that were conducted;

-   The methods that will be used for determining continuing compliance,
    including a description of monitoring and reporting requirements and
    test methods;

-   the year of purchase;

-   the manufacturer's site-rated brake horsepower;

-   the ambient temperature, pressure, and humidity measured during the
    performance test; and

-   all assumptions that were made to estimate or calculate percent load
    during the performance test must be clearly explained.

If measurement devices such as flow meters, kilowatt meters, beta
analyzers, stain gauges, etc. are used, the model number of the
measurement device, and an estimate of its accuracy in percentage of
true value must be provided.

After you have been issued a title V operating permit, you must comply
with all requirements for compliance status reports contained in your
title V permit. After you have been issued a title V operating permit,
you are required to submit the notification of compliance status to the
appropriate permitting authority following completion of the compliance
demonstrations specified in the RICE MACT.

1.  Semiannual Compliance Reports

You must submit semiannual compliance reports. The first compliance
report covers the period beginning on the compliance date for your
stationary RICE and ends on June 30 or December 31, whichever is the
first date following the end of the first calendar half after the
compliance date \[\'63.6650(b)(1)\]. The first compliance report is due
on either July 31 or January 31, whichever date follows the end of the
first calendar half after the compliance date \[\'63.6650(b)(2)\].
Subsequent reports cover the reporting periods from January 1 through
June 30 or July 1 through December 31 \[\'63.6650(b)(3)\]. Each
subsequent report is due either on July 31 or January 31, whichever is
the first date following the end of the semiannual reporting period
\[\'63.6650(b)(4)\].

Instead of the schedule just discussed, you may submit the first and
subsequent compliance reports on the dates established by your
permitting authority under title V operating permit regulations. Your
facility must be subject to title V operating permit regulations under
40 CFR part 70 or 71, and your permitting authority must have
established dates for submitting semiannual reports \[\'63.6650(b)(5)\].

The semiannual compliance report must contain the following information
\[\'63.6650(c), (d), and (e)\]:

    formaldehyde emission limits. Also include the number, duration, and
    a description of each type of malfunction that occurred during the
    reporting period and which caused or may have caused you to exceed
    your CO or formaldehyde emission limits.

-   If you revised your SSM plan during the reporting period, you must
    include the revision.

    CEMS) was out-of-control, a statement that there were no periods
    during which the CMS was out-of control during the reporting period.

-   A statement that during the reporting period there were no
    deviations from the emission limitations or operating limitations.

-   You must report each time you did not meet your emission limitation
    or operating limitation that apply to each stationary RICE. These
    instances are deviations from the emission and operating
    limitations.

-   For each deviation from an emission limitation or operating
    limitation for a stationary RICE where you are not using a CMS to
    comply with the emission or operating limitations, you must
    include: (1) The total operating time of the stationary RICE at
    which the deviation occurred during the reporting period and (2)
    Information on the number, duration, and cause of deviations
    (including unknown cause, if applicable), as applicable, and the

        1.  Immediate Startup, Shutdown, or Malfunction Reports

A startup, shutdown, and malfunction report must be submitted
immediately if any action taken during a startup, shutdown, or
malfunction during the reporting period are not consistent with your SSM
\[Table 7\]. You must report actions by phone or by fax within 2 days
after starting actions inconsistent with the SSM plan, followed by
letter within 7 days. The letter must include the name, title, and
signature of the responsible official who is certifying its accuracy, an
explanation of the circumstances of the event, the reasons for not
following the SSM plan, and a description of all excess emissions and/or
parameter monitoring exceedances which are believed to have occurred
\[\'63.10(d)(5)\].

**What are the MACT Requirements for 4-Stroke Lean Burn Engines?**

The purpose of this section is to provide a detailed summary of the MACT
requirements for 4-Stroke Lean Burn (4SLB) stationary RICE. Existing
4SLB stationary RICE do not have to meet any requirements under subpart
ZZZZ. For each new or reconstructed 4SLB stationary RICE subject to
Subpart ZZZZ, you have to comply with the full MACT requirements,
including emission limitations, operating limitations, and requirements
for performance tests, monitoring, recordkeeping and reporting. The
following sections provide a detailed summary of these requirements.

1.  What are the Emission Limitations?

2.  What are the Emission Testing Requirements?

3.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Using an Oxidation Catalyst?

4.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Not Using an Oxidation Catalyst?

5.  What are the Monitoring Requirements If I am using a CEMS?

6.  What are the Startup, Shutdown, and Malfunction Requirements?

7.  What Records Must I Keep?

8.  What Notification and Reports Must I Submit?

If you do not have a new or reconstructed 4SLB stationary RICE, you may
skip this section.

1.  **What Are The Emission Limitations?**

For each new or reconstructed spark ignition 4SLB stationary RICE
subject to Subpart ZZZZ, you must comply with ONE of the following
emission limitations at 100 percent load plus or minus 10 percent
\[Table 2a\]:

-   Reduce carbon monoxide (CO) emissions by 93 percent or more
    (referred to as the CO percent reduction limit); OR

-   Limit the formaldehyde concentration in the stationary RICE exhaust
    to 14 parts per million, by volume on a dry basis (ppmvd) at 15
    percent O~2~ (referred to as the formaldehyde concentration limit).

You may meet the applicable emission limitation by using an oxidation
catalyst or an alternative method of control. Whichever method of
control you choose, you will have emission testing requirements;
operating limits and parameter monitoring requirements; startup,
shutdown, and malfunction requirements; recordkeeping requirements; and
notification and reporting requirements. You will have different
operating limitations and monitoring requirements depending on the
method of control you choose. Refer to the summary of operating
parameter and monitoring requirements under section 6.3 if you are using
an oxidation catalyst and section 6.4 if you are using an alternative
method of control.

1.  **What Are The Emission Testing Requirements?**

You must conduct emission testing on new and reconstructed 4SLB engines
subject to Subpart ZZZZ to show that you are meeting ONE of the
applicable emission limitations (as discussed in Section 6.1). For MACT,
emission tests are called "performance tests." The following performance
tests are required for Subpart ZZZZ:

-   You must conduct an initial performance test for new and
    reconstructed 4SLB engines subject to Subpart ZZZZ (see section
    6.2.2).

-   You must conduct semiannual performance tests if your 4SLB
    stationary RICE is not equipped with a continuous emission monitor
    (CEM) AND you are complying with the CO percent reduction limit, or
    if you are complying with the formaldehyde concentration limit (see
    section 6.2.3).

-   If you are using an oxidation catalyst, to comply with Subpart ZZZZ,
    you also must conduct a performance test if you change your catalyst
    (see section 6.2.4).

In all cases, the emission tests must be conducted according to the
requirements included in Subpart ZZZZ, discussed below (see Section
6.2.1).

If you elect to install a CEMS to continuously monitor CO and either
oxygen or CO~2~, to demonstrate compliance with the CO percent reduction
limitation, you are required to conduct an initial performance
evaluation and relative accuracy test audit (RATA). You are not required
to conduct the performance tests specified in Table 4. Specific
requirements for CEMS are presented in section 6.5.

1.  How do I conduct my performance tests?

The following provisions apply to all performance tests:

-   You must conduct the tests using the test methods and other test
    procedures included in Table 4 of Subpart ZZZZ. These provisions are
    discussed further in Sections 6.2.1.1 and 6.2.1.2 below.

-   The tests must be conducted while the engine is operating at 100
    percent load plus or minus 10 percent. \[63.6620(b)\]

-   The tests must NOT be conducted during startup, shutdown, or
    malfunction (SSM) events (see section 6.6 of this document for
    details on SSM requirements) \[\'\'63.6620(c) and 63.7(e)(1)\].

-   The tests must include at least three separate test runs, and each
    test run must last at least one hour \[63.6620(d)\].

-   Operating parameters must be measured during the performance test
    (see section 6.2.2.1 for operating parameters)

-   Determination of engine load must be documented, including the
    calculations, assumptions, and measurement devices used to measure
    or estimate the percent load. This information must be submitted in
    a written report with the performance test results (see section
    6.8.4 of this document for the information that must be included in
    this report).

-   You must record ambient temperature, pressure, and humidity for the
    percent load determination and include the data in a written report
    (see section 6.8.4 of this document for the information that must be
    included in this report).

    1.  [What performance test requirements do I have to follow if I am
        complying with the CO percent reduction limitation?]{.underline}

If you are complying with the CO percent reduction limit, you must
conduct all of your performance tests using the following criteria
\[Table 4, item 1\].

1.  You must measure the O~2~ at the inlet and outlet of the oxidation
    catalyst or other control device with a portable CO and O~2~
    analyzer, using ASTM D6522-00[^79] (incorporated by reference,
    according to \'63.14). You must make measurements to determine O~2~
    at the same time as the measurements for CO concentration.

2.  You must measure the CO at the inlet and outlet of the oxidation
    catalyst or other control device with a portable CO and O~2~
    analyzer, using ASTM D6522-00[^80] (incorporated by reference,
    according to \'63.14). The CO concentration must be at 15% O~2~, dry
    basis

Determine compliance with the CO percent reduction requirement using the
following set of equations \[\'63.6620(e)\]:

1.  [What performance test requirements do I have to follow if I am
    complying with the formaldehyde concentration
    limitation?]{.underline}

If you are complying with the requirement to limit the formaldehyde
concentration you must conduct your initial and all subsequent
performance tests using the following criteria \[Table 4, item 3\]:

1.  You must select the location of the sampling port and the number of
    traverse points using Method 1 or 1A (40 CFR part 60, appendix A).
    You must choose a sampling site that is located at the outlet of the
    oxidation catalyst or other control device; AND

2.  You must determine the O~2~ concentration of the 4SLB stationary
    RICE exhaust at the sampling port location using Method 3, 3A or 3B
    (40 CFR part 60, appendix A). You must take the measurements to
    determine the O~2~ concentration at the same time and location as
    the measurements for the formaldehyde concentration; AND

3.  You must measure the moisture content of the 4SLB stationary RICE
    exhaust at the sampling port location using Method 4 (40 CFR part
    60, appendix A) or Method 320 (40 CFR part 63, appendix A) or ASTM D
    6348-03. You must take measurements to determine the moisture
    content at the same time and location as the measurements for the
    formaldehyde concentration; AND

4.  You must measure formaldehyde at the exhaust of the 4SLB stationary
    RICE using Method 320 or 323 (40 CFR part 60, appendix A), or ASTM
    D6348-03, [^81] provided in ASTM D6348-03 Annex A5 (Analyte Spiking
    Technique), the percent R must be [\>]{.underline} 70 and
    ­[\<]{.underline} 130. You must convert the formaldehyde
    concentration to 15% O~2~, dry basis. Results of this test consist
    of the average of the three 1-hr or longer runs.

    1.  Initial Performance Test

You must conduct an initial performance test for new or reconstructed
4SLB engines subject to Subpart ZZZZ to show that you are meeting either
the CO percent reduction limit or the formaldehyde concentration limit.
The initial performance test must be conducted using the methods and
test procedures presented in Section 6.2.1.

The results of the initial performance test must show that you have
reduced CO emissions by 93 percent or more or the formaldehyde
concentration in your stationary RICE exhaust is less than or equal to
14 ppmvd at 15 percent O~2~ \[\'63.6630(a)\].

1.  [Measuring Operating Parameters During the Initial Performance
    Test]{.underline}

If you use an oxidation catalyst to comply with MACT, and are NOT using
a CEMS, you must record two operating parameters during the initial
performance test (Table 5, items 1 and 6):

-   pressure drop across the catalyst; and

-   inlet temperature to the catalyst.

If you are not using an oxidation catalyst and EPA has approved your
petition to establish operating limitations, you must record parameters
during the initial performance test in accordance with EPA's approval of
your petition to establish operating limitations (Table 5, items 2 and
7). These values will be used to establish your operating limits (see
Sections 6.3 or 6.4 of this document). Note that you should not conduct
the initial performance test until EPA acts on your petition
\[\'63.6620(f)\].

If you are not using an oxidation catalyst and EPA approved your
petition EPA to establish NO operating limitations, you are not required
to record parameters during the initial performance test. Note that you
should not conduct the initial performance test until EPA acts on your
petition \[\'63.6620(f)\].

1.  [When do I have to conduct the initial performance
    test?]{.underline}

If construction/reconstruction of the new or reconstructed 4SLB
stationary RICE commences after June 15, 2004, you must conduct the
initial compliance test within 180 days after you start up the new or
reconstructed engine \[§63.6610(a)\].

If you have a new or reconstructed 4SLB stationary RICE that commenced
construction (or reconstruction) between December 19, 2002 and June 15,
2004, you have to conduct the initial performance test no later than
February 10, 2005 or no later than 180 days after startup of your
engine, whichever date is later \[§63.6610(b)\].

2.  [When is an initial performance test not required?]{.underline}

You do not have to perform an initial performance test if you have
conducted a performance test on your 4SLB stationary RICE that meets the
following criteria:

1.  The test was conducted using the same test methods specified in
    section 6.2.1.1 or 6.2.1.2 of this document, and you followed these
    methods correctly.

2.  The test is not older than 2 years.

3.  The test has been reviewed and accepted by EPA.

4.  No process or equipment changes have been made since the test was
    performed, or you can demonstrate that the results of the
    performance test, with or without adjustments, reliably demonstrate
    compliance despite process or equipment changes.

5.  The test was conducted at any load condition within
    ­[+]{.underline}10 percent of 100 percent load.

You are also not required to conduct an initial performance test if you
install a CEMS to continuously monitor CO and either O~2~ or CO~2~.
Instead, for each CEMS, you are required to conduct an initial
performance evaluation (see section 6.5 for more details regarding the
performance evaluation). You are required to conduct the initial
performance evaluation for each CEMS by February 12, 2005 or within 180
days after startup, whichever is later.

1.  Semiannual Performance Tests

You must conduct semi-annual performance tests if:

-   You are complying with the CO percent reduction limit AND your 4SLB
    stationary RICE is NOT equipped with a CEMS.

-   You are complying with the formaldehyde concentration limit
    \[\'63.6615 and Table 3\].

If you conduct two consecutive performance tests and are in compliance
with the applicable emission limitation, you may conduct the subsequent
performance tests on an annual basis. You must resume semi-annual tests
if:

-   Any subsequent performance test shows that you are not in compliance
    with your emission limit, or

-   You deviate from any of your operating limitations \[Table 3,
    footnote\].

    1.  Other Required Tests

If you are using a catalyst, such as an oxidation catalyst, to comply
with Subpart ZZZZ, and you change the catalyst, you are required to
conduct a performance test to show that you are meeting the applicable
emission limitation. You must also reestablish the values of the
operating parameters measured during the initial performance test
\[\'63.6640(b)\]. If you are using an oxidation catalyst to comply with
MACT, you must reestablish the initial pressure drop for the catalyst
and measure the inlet temperature to the catalyst during the
catalyst-change performance test.

2.  Reports and Notification for Performance Tests

The reports and notifications required for performance tests are
presented in the table below:

These reports and notifications are discussed further in Sections 6.7
and 6.8.

1.  **What Are The Operating Limits And Parameter Monitoring
    Requirements If I Am Using An Oxidation Catalyst?**

In addition to meeting emission limitations, you may also have to meet
certain operating limits. The operating limits for 4SLB engines are
presented in Table 2b of Subpart ZZZZ. If you choose to install a CEMS,
you do not have operating limits to comply with MACT. Section 6.5
presents your requirements if you choose to install a CEMS.

It is important to note that these operating limits are enforceable
independent of the emission limits -- they are not triggers to assess
your emissions. Instead they are separate and enforceable limits.

This section presents the operating limit and parameter monitoring
requirements if you are using an oxidation catalyst to meet the
applicable CO or formaldehyde emission limit. If you are not using an
oxidation catalyst, section 6.4 presents the operating limit and
parameter monitoring requirements for other control technologies.

The operating limits and parameter monitoring requirements are the same
for both the 93-percent CO percent reduction requirement and the
14-ppmvd formaldehyde concentration requirement.

1.  Operating Limits for 4SLB Engines using Oxidation Catalyst to Comply
    with MACT

Two operating limits apply for 4SLB engines using oxidation catalyst to
comply with MACT:

-   Maintain your catalyst so that the pressure drop across the catalyst
    does not change by more than two inches of water at 100 percent load
    plus or minus 10 percent from the pressure drop across the catalyst
    measured during the initial performance test; and

-   Maintain the temperature of your engine exhaust so that the catalyst
    inlet temperature is greater than or equal to 450F and less than or
    equal to 1350F.

Note that you establish the initial pressure drop across the catalyst
during the initial performance test. The allowable range for pressure
drop is 2" WC from the initial pressure drop. Also note that if you
change your catalyst, you are required to reestablish the initial
pressure drop for the new catalyst element.

As discussed further below, to demonstrate compliance with these
operating limits, you must measure pressure drop across the catalyst
monthly, and you must continuously monitor temperature at the catalyst
inlet (i.e., the stationary RICE exhaust temperature at the catalyst
inlet).

1.  Monthly Pressure Drop Measurements

You demonstrate that you are meeting the pressure drop operating limit
by measuring the pressure drop across the catalyst once a month \[Table
6, items 1 and 7\]. The monthly pressure drop measurements should be
taken while the engine is operating at 100% load 10%.

You are meeting the operating limit if the pressure drop measured each
month is within two inches of water of the pressure drop measured during
the performance test \[Table 2b, item 1\].

2.  Continuous Catalyst Inlet Temperature Monitoring

You are required to install and operate a continuous parameter
monitoring system (CPMS) to measure catalyst inlet temperature \[Table
5, items 1 and 6\]. You must collect the catalyst inlet temperature data
and reduce these data to 4-hour rolling averages \[Table 6, items 1 and
7\].[^82] You are meeting the oxidation catalyst inlet temperature
operating limit if the 4-hour rolling average oxidation catalyst inlet
temperature is greater than or equal to 450^o^F or less than or equal to
1,350^o^F \[Table 2b, item 1\].

3.  Continuous Parameter Monitoring System Requirements

For each stationary RICE, you are required to install a CPMS to
continuously monitor catalyst inlet temperature (Table 5, items 1 and
6). For each CPMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for your CPMS
\[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 6.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^83] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^84] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 6.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time as the
notification to conduct your performance test.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CPMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance test or performance evaluation is scheduled to
begin, or on a mutually agreed upon date. The Administrator will review
and approve the performance evaluation test plan at the same time as the
review and approval of the site-specific test plan (if review of the
site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Operating Limits and Parameter Monitoring
        Requirements If I am not Using Oxidation Catalyst?**

If you choose to meet the CO or formaldehyde emission limits using a
control technique other than oxidation catalyst, you are required to
petition the Administrator for approval of operating limitations to be
established during the initial performance test. If you feel that no
operating limits are appropriate for your technology, you may also
petition the Administrator for approval of no operating limitations.
Your petition has to receive approval from the Administrator before you
can conduct your initial performance test \[\'63.6620(f)\].

1.  Petition for Approval of Operating Limitations

If you petition the Administrator for approval of operating limitations,
the petition must contain the following information \[\'63.6620(g)\]:

-   You must identify the specific parameters you propose to use as
    operating limitations;

-   You must provide a discussion of the relationship between these
    parameters and HAP emissions, identifying how HAP emissions change
    with changes in these parameters, and how limitations on these
    parameters will serve to limit HAP emissions;

-   You must provide a discussion of how you will establish the upper
    and/or lower values for these parameters which will establish the
    limits on these parameters in the operating limitations;

-   You must provide a discussion identifying the methods you will use
    to measure and the instruments you will use to monitor these
    parameters, as well as the relative accuracy and precision of these
    methods and instruments; and

-   You must provide a discussion identifying the frequency and methods
    for recalibrating the instruments you will use for monitoring these
    parameters.

    1.  Petition for Approval of No Operating Limitations

If you petition the Administrator for approval of no operating
limitations, your petition must include the following information
\[\'63.6620(h)\]:

-   You must identify the parameters associated with operation of the
    stationary RICE and the emission control device which could change
    intentionally (e.g., operator adjustment, automatic controller
    adjustment, etc.) or unintentionally (e.g., wear and tear, error,
    etc.) on a routine basis or over time;

-   You must provide a discussion of the relationship, if any, between
    changes in the parameters and changes in HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of whether establishing
    limitations on the parameters would serve to limit HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of how you could
    establish upper and/or lower values for the parameters which would
    establish limits on the parameters in operating limitations;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the methods
    you could use to measure them and the instruments you could use to
    monitor them, as well as the relative accuracy and precision of the
    methods and instruments;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the
    frequency and methods for recalibrating the instruments you could
    use to monitor them; and

```{=html}
<!-- -->
```
-   You must provide a discussion of why, from your point of view, it is
    infeasible or unreasonable to adopt the parameters as operating
    limitations.

    1.  Continuous Parameter Monitoring System Requirements

If you have petitioned the Administrator for operating limitations, for
each stationary RICE you are required to install a continuous parameter
monitoring system (CPMS) to continuously monitor your approved operating
parameters. For each CPMS, you are required to follow certain operation
and maintenance requirements; prepare a quality control program; and
conduct performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for operation
of your CPMS \[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 6.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^85] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^86] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 6.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time you
submit the notification to conduct your performance test. If you are not
conducting a performance test, the performance evaluation notification
must be submitted at least 60 days prior to the date that you are
scheduled to begin the performance evaluation.

Before conducting the performance evaluation, you may be required to
develop and submit a site-specific performance evaluation test plan to
the Administrator for approval. The following elements must be included
in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

If the Administrator requests that you submit a site-specific
performance evaluation test plan for approval, it is due at least 60
days before the performance test or performance evaluation is scheduled
to begin, or on a mutually agreed upon date. The Administrator will
review and approve the performance evaluation test plan at the same time
as the review and approval of the site-specific test plan (if review of
the site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently chooses to use the
    specified monitoring method(s) instead of an alternative.

    1.  Requirements for Approved Operating Limits

You are required to install and operate a CPMS to measure your approved
operating limit \[Table 5, items 2 and 7\]. You must collect the
parameter data you approved by the Administrator and reduce these data
to 4-hour rolling averages \[Table 6, items 2 and 8\].[^87] You are
meeting the approved operating limit if the 4-hour rolling average
parameter data is within your approved operating limitations for the
operating parameters established during the initial performance test.

1.  **What are the Monitoring Requirements If I am using a CEMS?**

If you are complying with the CO percent reduction emission limitation,
you have the option of installing a CEMS to demonstrate that you are
reducing CO by 93 percent or more. You may choose this option for any
control technique. You must install a CEMS to continuously monitor CO
and either oxygen or CO~2~ at both the inlet and outlet of the control
device according to the following \[§63.6625(a)\]:

-   You must install, operate and maintain each CEMS as specified in
    performance specifications (PS) 3 and 4A of 40 CFR part 60, appendix
    B.

-   You must conduct an initial performance evaluation and an annual
    relative accuracy test audit (RATA) according to \'63.8 and PS 3 and
    4 (40 CFR part 60, appendix B).

-   You must conduct daily and periodic data quality checks specified in
    40 CFR part 60, appendix F, procedure 1.

-   You must install the CEMS such that a minimum of one cycle of
    operation (sampling, analyzing, and data recording) is completed for
    each successive 15-minute period. There must be two data points,
    with each representing a different 15-minute period, to have a valid
    hour of data.

-   You must reduce the CEMS data to 1-hour averages computed from four
    or more data points equally spaced over each 1-hour period, except
    during periods when calibration, quality assurance, or maintenance
    activities are being performed. During these periods, an hourly
    average is considered valid if you have at least two data points,
    each representing a 15-minute period. NOTE: You may also use an
    arithmetic or integrated 1-hour average of CEMS data.

-   You must also keep records of the reduced data in parts per million
    at 15 percent oxygen or the equivalent CO~2~ concentration.

    1.  Initial Performance Evaluation Requirements

For each CEMS, you must conduct an initial performance evaluation and an
initial RATA using the procedures specified in §63.8 and PS 3 (for
oxygen or CO~2~) and 4A (for CO) of 40 CFR part 60, appendix B. You are
not required to conduct the performance tests specified in Table 4. The
initial performance evaluation must be conducted by February 12, 2005 or
within 180 days after startup of your new or reconstructed stationary
RICE, whichever date is later.

Once the performance evaluation has been completed you must calculate
the average CO percent reduction. This calculation is based on the first
four hours of monitoring data collected once the CEMS has been
successfully validated \[Table 5, item 3.a.iii\].

Determine compliance with the CO percent reduction requirement using the
following set of equations \[\'63.6620(e)\]:

2.  Additional Requirements

You are required to conduct annual RATA of each CEMS using PS 3 (for
oxygen or CO~2~) and PS 4A (for CO) \[40 CFR part 60, appendix B\], as
well as the daily and periodic data quality checks specified in 40 CFR
part 60, appendix F, procedure 1.

You must collect monitoring data (see section 6.5.3 for specific
monitoring installation, operation, and maintenance requirements) and
reduce the measurements to one-hour averages and calculate the percent
reduction of CO emissions using the formulas presented in section 6.5.1.
You must collect the one-hour average CO percent reduction data and
reduce these data to 4-hour rolling averages \[Table 6, item 3\].[^88]
You are meeting the CO percent reduction emission limit if the 4-hour
rolling average CO percent reduction is greater than or equal to 93
percent.

3.  Continuous Emission Monitoring System Requirements

For each CEMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CEMS]{.underline}

There are several operation and maintenance requirements for your CEMS
\[§63.8(c)\]:

-   You must operate the CEMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CEMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CEMS (see section 6.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CEMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CEMS operational and have the data
    verified either prior to or during the initial performance
    evaluation (you verify the operational status of your CEMS by, at a
    minimum, completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CEMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   Each CEMS must complete a minimum of one cycle of operation (i.e.,
    sampling, analyzing, and data recording) for each successive
    15-minute period;

-   You must check the zero (low-level) and high-level calibration
    drifts of each CEMS installed according to PS 3 (for oxygen or
    CO~2~) or PS 4A (for CO) at least once daily according to your
    performance evaluation plan (see section 6.5.1.3). You must adjust
    the zero (low-level) and high-level calibration drifts, at a
    minimum, whenever the 24-hour zero (low-level) drift exceeds two
    times the limits specified in the PS. The system must allow the
    amount of excess zero (low-level) and high-level drift measured at
    the 24-hour interval checks to be recorded and quantified whenever
    specified.

-   If you have a CEMS that is out of control, [^89] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CEMS is out of control
    in data averages or calculations.

-   If you have a CEMS that is out of control,[^90] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 6.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CEMS \[§63.8(d)\]. The program must contain a written protocol that
describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CEMS;

-   Determination and adjustment of the calibration drift of the CEMS;

-   Preventive maintenance of the CEMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CEMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CEMS
\[§63.8(e)\]. You must conduct this performance evaluation by February
12, 2005 or within 180 days after startup, whichever is later. You are
required to notify the Administrator in writing of the date that you are
going to conduct your performance evaluation at least 60 days before the
performance evaluation is scheduled to begin.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CEMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance evaluation is scheduled to begin, or on a
mutually agreed upon date. The Administrator will review and approve the
performance evaluation test plan. The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Startup, Shutdown, and Malfunction (SSM)
        Requirements?**

You are required to operate your oxidation catalyst or other control
device as well as any CPMS or CEMS at all times, including periods of
startup, shutdown, and malfunction (SSM), in a safe manner and according
to good air pollution control practices to minimize emissions.

A startup is defined as "the setting in operation of an affected source
or portion of an affected source for any purpose." \[§63.2\]

A shutdown is defined as "the cessation of operation of an affected
source or portion of an affected source for any purpose." \[§63.2\]

A malfunction is defined as "any sudden, infrequent, and not reasonably
preventable failure of air pollution control and monitoring equipment,
process equipment, or a process to operate in a normal or usual manner
which causes, or has the potential to cause, the emission limitations in
an applicable standard to be exceeded. Failures that are caused in part
by poor maintenance or careless operation are not malfunctions."
\[§63.2\]

1.  What are my requirements during SSM events?

You are responsible for reducing emissions to the greatest extent
possible and maintain safety and good air control practices whenever
there is a period of SSM. This does not mean that you are required to
achieve the emission levels required under the RICE MACT during SSM
events if it means that you would not be operating in a safe manner and
with good air pollution practices nor are you required to make any
further efforts to reduce emissions if you are meeting the emission
levels required by the RICE MACT.

2.  Startup, Shutdown and Malfunction Plan

You are required to develop and implement a written startup, shutdown,
and malfunction (SSM) plan that describes, in detail, procedures for
operating and maintaining the each stationary RICE during periods of
SSM, and a program of corrective action for malfunctioning process and
air pollution control and monitoring equipment (i.e., oxidation catalyst
or other control device, pressure drop monitoring equipment, and CPMS or
CEMS). You must develop this plan by August 16, 2004 if construction or
reconstruction of your new or reconstructed stationary RICE commenced on
or after December 19, 2002 but before August 16, 2004. If construction
or reconstruction of your new or reconstructed stationary RICE began
after August 16, 2004, you must have your SSM plan developed by startup
\[§63.6(e)(3)(i)\].

During periods of SSM, you must operate and maintain your stationary
RICE (including each oxidation catalyst or other control device and
monitoring equipment) in accordance with the procedures specified in
your SSM plan \[§63.6(e)(3)(ii)\].

1.  [What must be included in my SSM plan?]{.underline}

EPA does not specify the required elements of a SSM plan, but the SSM
plan must address the following \[§63.6(e)(3)(i)(A) through (C)\]:

1.  Ensure that, at all times, you operate and maintain each stationary
    RICE, including your oxidation catalyst or other control device and
    monitoring equipment, in a manner which satisfies your general duty
    to minimize emissions;

2.  Ensure that you are prepared to correct malfunctions as soon as
    practicable after their occurrence in order to minimize excess
    emissions of hazardous air pollutants; and

3.  Reduce the reporting burden associated with periods of startup,
    shutdown, and malfunction (including corrective action taken to
    restore malfunctioning process and air pollution control equipment
    to its normal or usual manner of operation).

To develop your SSM plan, you may use your standard operating procedures
(SOP) manual, or an Occupational Safety and Health Administration (OSHA)
or other plan, provided the alternative plans meet the SSM plan
requirements and are made available for inspection or submitted when
requested by EPA or the delegated authority \[§63.6(e)(3)(vi)\].

1.  [When may the SSM plan be revised?]{.underline}

You may periodically revise the SSM plan for your stationary RICE as
necessary to satisfy the requirements of 40 CFR part 63 or to reflect
changes in equipment or procedures at the affected source. Unless EPA or
your permitting authority provides otherwise, you may make such
revisions to the startup, shutdown, and malfunction plan without prior
approval by EPA or the permitting authority \[§63.6(e)(3)(viii)\].
However, each revision to a SSM plan must be reported in the semiannual
compliance report (see section 6.8.6).

If the SSM plan fails to address or inadequately addresses an event that
meets the characteristics of a malfunction but was not included in the
SSM plan at the time you developed the plan, you must revise the SSM
plan within 45 days after the event to include detailed procedures for
operating and maintaining the source during similar malfunction events
and a program of corrective action for similar malfunctions of process
or air pollution control and monitoring equipment \[§63.6(e)(3)(viii)\].

In the event that you make any revision to the SSM plan which alters the
scope of the activities which are deemed to be an SSM, or otherwise
modify the applicability of any emission limit or other RICE MACT
requirement, the revised plan may not take effect until after you have
provided a written notice describing the revision to your permitting
authority \[§63.6(e)(3)(viii)\].

If EPA or the delegated authority determines that you are not operating
and maintaining your stationary RICE (including the oxidation catalyst
or other control device and monitoring equipment) in such a way that is
consistent with safety and good air pollution control practices
\[§63.6(e)(1)(i)\], EPA or the delegated authority may require you to
make changes to the SSM plan for that stationary RICE. EPA or the
delegated authority must require appropriate revisions to a SSM plan, if
EPA or the delegated authority finds that the plan \[§63.6(e)(3)(vii)\]:

-   Does not address a SSM event that has occurred;

-   Fails to provide for the operation of the stationary RICE (including
    the oxidation catalyst or other control device and monitoring
    equipment) during a SSM event in a manner consistent with the
    general duty to minimize emissions established by §63.6(e)(1)(i);

-   Does not provide adequate procedures for correcting malfunctioning
    process and/or air pollution control and monitoring equipment as
    quickly as practicable; or

-   Includes an event that does not meet the definition of startup,
    shutdown, or malfunction listed in §63.2.

The title V permit for a stationary RICE must require that you adopt a
SSM plan which conforms to part 63, and that you operate and maintain
the stationary in accordance with the procedures specified in the
current SSM plan. However, any revisions made to the SSM plan as
specified above do not constitute permit revisions under part 70 or part
71 of this chapter. Moreover, none of the procedures specified by the
SSM plan for an affected source shall be deemed to fall within the
permit shield provision in section 504(f) of the Act
\[§63.6(e)(3)(ix)\].

1.  [What are my requirements for maintaining my SSM plan?]{.underline}

You must maintain a current SSM plan and must make the plan available
upon request for inspection and copying by the EPA or delegated
authority. In addition, if you subsequently revise your SSM plan (see
section 6.6.2.2), you must keep each previous (i.e., superseded) version
of the SSM plan, and must make each such previous version available for
inspection and copying by the EPA or the delegated authority for 5 years
after revision of the plan. If at any time after adoption of an SSM plan
the stationary RICE ceases operation or is otherwise no longer subject
to the RICE MACT, you must keep a copy of the most recent plan for 5
years from the date the stationary RICE ceases operation or is no longer
subject the RICE MACT and must make the plan available upon request for
inspection and copying by EPA or the delegated authority
\[§63.6(e)(3)(v)\].

EPA or the delegated authority may at any time request in writing that
you submit a copy of any SSM plan (or a portion thereof). Upon receipt
of such a request, you must promptly submit a copy of the requested plan
(or a portion thereof) to EPA or the delegated authority. EPA or the
delegated authority must request that you submit a particular SSM plan
(or a portion thereof) whenever a member of the public submits a
specific and reasonable request to examine or to receive a copy of that
plan or portion of a plan. You may elect to submit the required copy of
any SSM plan in an electronic format. If you claim that any portion of
such a SSM plan is confidential business information entitled to
protection from disclosure under section 114(c) of the Act or 40 CFR
2.301, the material which is claimed as confidential must be clearly
designated in the submission. \[§63.6(e)(3)(v)\]

1.  How do I demonstrate I am following my SSM plan?

When you take actions during a period of SSM (including actions taken to
correct a malfunction) that are consistent with the procedures specified
in the SSM plan developed for your stationary RICE, you must do the
following \[§63.6(e)(iii)\]:

-   You must keep records for that event which demonstrate that the
    procedures specified in the plan were followed. These records may
    take the form of a "checklist," or other form of recordkeeping that
    confirms that you followed the procedures defined in your SSM plan
    for that event.

-   You must keep the following records of these events
    \[§63.10(b)(2)\]:

    -   Records of the occurrence and duration of each startup,
        shutdown, or malfunction of operation

    -   Records of the occurrence and duration of each malfunction of
        the oxidation catalyst or other control device and monitoring
        equipment

-   You must confirm that actions taken during the relevant reporting
    period during periods of SSM were consistent with the startup,
    shutdown and malfunction plan developed for each stationary RICE in
    the semiannual (or more frequent) startup, shutdown, and malfunction
    report required in §63.10(d)(5). Note that this information may also
    be incorporated into your semiannual compliance report (see section
    6.8.6).

If you take an action during a startup, shutdown, or malfunction
(including an action taken to correct a malfunction) that is not
consistent with the procedures specified in your stationary RICE\'s
startup, shutdown, and malfunction plan, and the stationary RICE exceeds
the applicable emission limitation, then you must record the actions
taken for that event and must report such actions within 2 working days
after commencing actions inconsistent with the plan, followed by a
letter within 7 working days after the end of the event, in accordance
with §63.10(d)(5) (unless the owner or operator makes alternative
reporting arrangements, in advance, with the Administrator)
\[§63.6(e)(3)(iv)\].

1.  **What Records Must I Keep?**

You are required to keep records of activities required to meet the
final RICE MACT. You must keep files of all information (including
reports and notifications) required under the RICE MACT in a format
suitable and readily available for "expeditious inspection and review
\[\'63.6660(a)\]." You must maintain these records for 5 years following
the date of each occurrence, measurement, maintenance, corrective
action, report, or record \[\'63.6660(b)\]. Records may be kept in hard
copy or electronic form. You may retain at least 2 years of records
on-site. You can keep records off-site for the remaining 3 years
\[\'63.6660(c)\].

1.  Recordkeeping Requirements for Notifications and Reports

You are required to keep a copy of each notification and report that you
have submitted as a part of complying with the RICE MACT, including all
documentation supporting any notification or report \[\'63.6655(a)(1)\].
You must maintain records of the following notifications and reports
(see section 6.8 of this document for details regarding these
notifications and reports):

-   Initial Notification;

-   Notifications of performance tests;

-   Site-specific test plan;

-   Notification of performance evaluation for continuous monitoring
    systems (CMS), including both CPMS and CEMS;

-   Site-specific performance evaluation plan(s);

-   Any request to use an alternative monitoring procedure;

-   Any request for extension of compliance;

-   Notification that your source is subject to special compliance
    requirements;

-   Notification of compliance status, including performance test
    results and written report to document engine load conditions during
    the test;

-   Semiannual compliance reports; and

-   Startup, shutdown, and malfunction reports.

    1.  Recordkeeping Requirements for Startup, Shutdown, and
        Malfunction Events

You are required to keep records related to startup, shutdown and
malfunction (SSM) events as follows (see section 6.6 for details on SSM
events) \[\'\'63.6655(a)(2) and 63.6(e)(3)(iii) through (v):

-   When you take actions during an SSM event (including actions taken
    to correct a malfunction), that are consistent with the procedures
    specified your SSM plan, you must keep records which demonstrate
    that the procedures specified in the plan were followed. You may
    keep records in the form of a "checklist," or you may choose another
    form of recordkeeping that documents that you have followed your SSM
    plan for that event.

-   You must keep records of these SSM events, including records of the
    occurrence and duration of each startup, shutdown, or malfunction of
    operation and each malfunction of the air pollution control and
    monitoring equipment.

-   When you take actions during an SSM event that are not consistent
    with the procedures specified in the your SSM plan, and the
    stationary RICE exceeds the formaldehyde emission limitations, then
    you must record the actions taken for that event.

-   You must maintain a current SSM plan and must make the plan
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your SSM plan, you are
    required to keep a copy of each previous (i.e., superseded) version
    of the SSM plan for 5 years after each revision. Previous versions
    must be available for inspection and copying by the Administrator.

-   If at any time after adoption of a SSM plan stationary RICE ceases
    operation or is otherwise no longer subject to the RICE MACT, you
    must retain a copy of the most recent plan for 5 years from the date
    the stationary RICE ceases operation or is no longer subject to the
    RICE MACT. This plan must be available upon request for inspection
    and copying by the Administrator.

-   The Administrator may request in writing that you submit a copy of
    any SSM plan (or portion of the plan). Upon receipt of such a
    request, you must promptly submit a copy of the requested plan (or
    portion of the plan) to the Administrator. The Administrator is
    required to request that you submit a particular SSM plan (or a
    portion thereof) whenever a member of the public submits a specific
    and reasonable request to examine or to receive a copy of that plan
    or portion of a plan. You may elect to submit the required copy of
    any SSM plan to the Administrator in an electronic format. If you
    claim that any portion of such a SSM plan is confidential business
    information entitled to protection from disclosure under section
    114(c) of the Act or 40 CFR 2.301, the material which is claimed as
    confidential must be clearly designated in the submission.

    1.  Recordkeeping Requirements for Performance Tests and CMS

You are required to keep records of all performance test and performance
evaluation results. Performance test results may include analysis of
samples, determination of emissions, and raw data \[\'\'63.6655(b) and
63.10(b)(2)(viii)\].

For each CMS (this includes CPMS and CEMS), you are required to keep the
following records \[\'\'63.6655(b) and 63.10(b)(2)(vi) through (xi)\]:

-   All CMS performance evaluations;

-   Records of each period during which the CMS is malfunctioning or
    inoperative (including periods where the CMS is out of control);

-   All required measurements needed to demonstrate compliance with the
    operating limitations or the CO percent reduction emission
    limitation (including, but not limited to, 15-minute averages of
    CPMS data, raw performance testing measurements, and raw performance
    evaluation measurements, that support data that you are required to
    report);

    -   For each CEMS that is automated[^91] and where the calculated
        data averages do not exclude periods of CEMS breakdowns or
        malfunction, rather than maintain a file of all CEMS subhourly
        measurements, you must retain the most recent consecutive three
        averaging periods of subhourly measurements and a file that
        contains a hard copy of the data acquisition system algorithm
        used to reduce the measured data into the reportable form of the
        standard.

    -   For each CEMS where measured data is manually reduced to the
        form of the emission limit, and where calculated data averages
        do not exclude periods of CEMS breakdowns or malfunctions,
        rather than maintain a file of all CEMS subhourly measurements,
        you must retain all subhourly measurements for the most recent
        reporting period. You must retain the subhourly measurements for
        120 days from the date of the most recent semiannual compliance
        report submitted to EPA.

    -   EPA or the delegated authority MAY require you to maintain all
        subhourly records if it is determined that these records are
        required to more accurately assess the compliance status of your
        stationary RICE. You will be notified of this requirement

-   All measurements as may be necessary to determine the conditions of
    performance tests and performance evaluations;

-   All CMS calibration checks;

-   All adjustments and maintenance performed on CMS;

-   You must maintain a current performance evaluation test plan and
    quality control procedures and must make these written procedures
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your performance evaluation
    plan, you are required to keep a copy of each previous (i.e.,
    superseded) version of the plan for 5 years after each revision
    \[\'63.8(d)(3)\]. Previous versions must be available for inspection
    and copying by the Administrator. If it is relevant, you may
    incorporate these procedures as part of your SSM plan.

You are also required to keep records of the following \[§63.10(c)(1)
through (14)\]:

-   All required CMS measurements (including monitoring data recorded
    during unavoidable CMS breakdowns and out-of-control periods);

-   The date and time identifying each period during which the CMS was
    inoperative except for zero (low-level) and high-level checks;

-   The date and time identifying each period during which the CMS was
    out of control;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during startups, shutdowns, and
    malfunctions;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during periods other than
    startups, shutdowns, and malfunctions;

-   The nature and cause (if known) of any malfunction;[^92]

-   The corrective action taken or preventative measures adopted;[^93]

-   The nature of the repairs or adjustments to the CMS that was
    inoperative or out of control;[^94]

-   The total process operating time during the reporting period; and

-   All procedures that are a part of a quality control program and
    implemented for CMS under §63.8(d).

    1.  Recordkeeping Requirements for Monitoring Data

You are required to keep records of all monitoring data you collect to
demonstrate compliance with your operating limitations \[Table 6, items
1, 2, 7, and 8\] or emission limitation \[Table 6, item 3\].

If you are using an oxidation catalyst you must keep records of the
catalyst inlet temperature data measured by your CPMS and the monthly
pressure drop measurements. If you are not using an oxidation, you are
required to keep records of the approved operating parameter. If you are
using a CEMS you are required to keep records of CO and oxygen or CO~2~
data measured by your CEMS.

1.  **What Notifications and Reports Must I Submit?**

For each notification and report, you send a copy to both your State Air
Pollution Control Office and your EPA Regional Office. Appendix B
contains a list of Regional EPA offices and addresses.

1.  Initial Notification

The initial notification states that your affected source is subject to
the RICE standards. If you have a new or reconstructed 4SLB engine that
you startup before August 16, 2004 you are required to submit the
initial notification no later than December 13, 2004
\[\'63.6645(b)\]**.**

If you startup your new or reconstructed stationary RICE on or after
August 16, 2004, you are required to submit your initial notification
within 120 days after your stationary RICE becomes subject to the RICE
MACT \[\'63.6645(c)\].

You are required to provide the following information in the initial

an analysis of samples, determination of emissions, and the raw data.
The initial performance test results may be submitted with the
notification of compliance status.

4.  Notification of Compliance Status

If you have chosen to install a CEMS to continuously monitor CO and
oxygen or CO2 to comply with the CO percent reduction emission
limitation, you must submit your Notification of Compliance Status
within 30 days following the completion of your performance evaluation
\[§63.6645(f)(1)\].

For all other 4SLB stationary RICE for which you do not install a CEMS,
you must submit the Notification of Compliance Status within 60 days
following the completion of the performance test \[\'63.6645(f)(2)\].

The Notification of Compliance Status certifies that your stationary
RICE is meeting the emission limitations and operating limitations;
identifies the option(s) you used to demonstrate initial compliance,
summarizes the data and calculations supporting the compliance
demonstration, and describes how you will determine continuous
compliance.

The Notification of Compliance Status must be signed by a responsible
official certifying its accuracy, attesting to whether all stationary
RICE are complying with the RICE MACT. The Notification of Compliance
Status must contain the following information \[\'63.9(h)(2)(i)\]:

-   The methods that were used to determine compliance;

-   The results of any performance tests, CMS performance evaluations,
    and/or other monitoring procedures or methods that were conducted;

-   The methods that will be used for determining continuing compliance,
    including a description of monitoring and reporting requirements and
    test methods;

    performance test; and

-   all assumptions that were made to estimate or calculate percent load
    during the performance test must be clearly explained.

If measurement devices such as flow meters, kilowatt meters, beta
analyzers, stain gauges, etc. are used, the model number of the
measurement device, and an estimate of its accuracy in percentage of
true value must be provided.

After you have been issued a title V operating permit, you must comply
with all requirements for compliance status reports contained in your
title V permit. After you have been issued a title V operating permit,
you are required to submit the notification of compliance status to the
appropriate permitting authority following completion of the compliance
demonstrations specified in the RICE MACT.

1.  Semiannual Compliance Reports

You must submit semiannual compliance reports. The first compliance
report covers the period beginning on the compliance date for your
stationary RICE and ends on June 30 or December 31, whichever is the
first date following the end of the first calendar half after the
compliance date \[\'63.6650(b)(1)\]. The first compliance report is due
on either July 31 or January 31, whichever date follows the end of the
first calendar half after the compliance date \[\'63.6650(b)(2)\].
Subsequent reports cover the reporting periods from January 1 through
June 30 or July 1 through December 31 \[\'63.6650(b)(3)\]. Each
subsequent report is due either on July 31 or January 31, whichever is
the first date following the end of the semiannual reporting period
\[\'63.6650(b)(4)\].

Instead of the schedule just discussed, you may submit the first and
subsequent compliance reports on the dates established by your
permitting authority under title V operating permit regulations. Your
facility must be subject to title V operating permit regulations under
40 CFR part 70 or 71, and your permitting authority must have
established dates for submitting semiannual reports \[\'63.6650(b)(5)\].

The semiannual compliance report must contain the following information
\[\'63.6650(c), (d), and (e)\]:

    CEMS) was out-of-control, a statement that there were no periods
    during which the CMS was out-of control during the reporting period.

-   A statement that during the reporting period there were no
    deviations from the emission limitations or operating limitations.

-   You must report each time you did not meet your emission limitation
    or operating limitation that apply to each stationary RICE. These
    instances are deviations from the emission and operating
    limitations.

-   For each deviation from an emission limitation or operating
    limitation for a stationary RICE where you are not using a CMS to
    comply with the emission or operating limitations, you must
    include: (1) The total operating time of the stationary RICE at
    which the deviation occurred during the reporting period and (2)
    Information on the number, duration, and cause of deviations
    (including unknown cause, if applicable), as applicable, and the

A startup, shutdown, and malfunction report must be submitted
immediately if any action taken during a startup, shutdown, or
malfunction during the reporting period are not consistent with your SSM
plan \[Table 7\]. You must report actions by phone or by fax within
2 days after starting actions inconsistent with the SSM plan, followed
by letter within 7 days. The letter must include the name, title, and
signature of the responsible official who is certifying its accuracy, an
explanation of the circumstances of the event, the reasons for not
following the SSM plan, and a description of all excess emissions and/or
parameter monitoring exceedances which are believed to have occurred
\[\'63.10(d)(5)\].

3.  **What are the MACT Requirements for Compression Ignition Engines?**

The purpose of this section is to provide a detailed summary of the MACT
requirements for compression ignition (CI) stationary RICE. Existing CI
stationary RICE do not have to meet any requirements under subpart ZZZZ.
For each new or reconstructed CI stationary RICE subject to Subpart
ZZZZ, you have to comply with the full MACT requirements, including
emission limitations, operating limitations, and requirements for
performance tests, monitoring, recordkeeping and reporting. The
following sections provide a detailed summary of these requirements.

1.  What are the Emission Limitations?

2.  What are the Emission Testing Requirements?

3.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Using an Oxidation Catalyst?

4.  What are the Operating Limits and Parameter Monitoring Requirements
    If I Am Not Using an Oxidation Catalyst?

5.  What are the Monitoring Requirements If I am using a CEMS?

6.  What are the Startup, Shutdown, and Malfunction Requirements?

7.  What Records Must I Keep?

8.  What Notification and Reports Must I Submit?

If you do not have a new or reconstructed CI stationary RICE, you may
skip this section.

1.  **What Are The Emission Limitations?**

For each new or reconstructed CI stationary RICE subject to Subpart
ZZZZ, you must comply with ONE of the following emission limitations at
100 percent load plus or minus 10 percent \[Table 2a\]:

-   Reduce carbon monoxide (CO) emissions by 70 percent or more
    (referred to as the CO percent reduction limit); OR

-   Limit the formaldehyde concentration in the stationary RICE exhaust
    to 580 parts per billion, by volume on a dry basis (ppbvd) at 15
    percent O~2~ (referred to as the formaldehyde concentration limit).

You may meet the applicable emission limitation by using an oxidation
catalyst or an alternative method of control. Whichever method of
control you choose, you will have emission testing requirements;
operating limits and parameter monitoring requirements; startup,
shutdown, and malfunction requirements; recordkeeping requirements; and
notification and reporting requirements. You will have different
operating limitations and monitoring requirements depending on the
method of control you choose. Refer to the summary of operating
parameter and monitoring requirements under section 7.3 if you are using
an oxidation catalyst and section 7.4 if you are using an alternative
method of control.

1.  **What Are The Emission Testing Requirements?**

You must conduct emission testing on new and reconstructed CI engines
subject to Subpart ZZZZ to show that you are meeting ONE of the
applicable emission limitations (as discussed in Section 7.1). For MACT,
emission tests are called "performance tests." The following performance
tests are required for Subpart ZZZZ:

-   You must conduct an initial performance test for new and
    reconstructed CI engines subject to Subpart ZZZZ (see section
    7.2.2).

-   You must conduct semiannual performance tests if your CI stationary
    RICE is not equipped with a continuous emission monitor (CEM) AND
    you are complying with the CO percent reduction limit, or if you are
    complying with the formaldehyde concentration limit (see section
    7.2.3).

-   If you are using an oxidation catalyst, to comply with Subpart ZZZZ,
    you also must conduct a performance test if you change your catalyst
    (see section 7.2.4).

In all cases, the emission tests must be conducted according to the
requirements included in Subpart ZZZZ, discussed below (see Section
7.2.1).

If you elect to install a CEMS to continuously monitor CO and either
oxygen or CO~2~, to demonstrate compliance with the CO percent reduction
limitation, you are required to conduct an initial performance
evaluation and relative accuracy test audit (RATA). You are not required
to conduct the performance tests specified in Table 4. Specific
requirements for CEMS are presented in section 7.5.

1.  How do I conduct my performance tests?

The following provisions apply to all performance tests:

-   You must conduct the tests using the test methods and other test
    procedures included in Table 4 of Subpart ZZZZ. These provisions are
    discussed further in Sections 7.2.1.1 and 7.2.1.2 below.

-   The tests must be conducted while the engine is operating at 100
    percent load plus or minus 10 percent. \[63.6620(b)\]

-   The tests must NOT be conducted during startup, shutdown, or
    malfunction (SSM) events (see section 7.6 of this document for
    details on SSM requirements) \[\'\'63.6620(c) and 63.7(e)(1)\].

-   The tests must include at least three separate test runs, and each
    test run must last at least one hour \[63.6620(d)\].

-   Operating parameters must be measured during the performance test
    (see section 7.2.2.1 for operating parameters)

-   Determination of engine load must be documented, including the
    calculations, assumptions, and measurement devices used to measure
    or estimate the percent load. This information must be submitted in
    a written report with the performance test results (see section
    7.8.4 of this document for the information that must be included in
    this report).

-   You must record ambient temperature, pressure, and humidity for the
    percent load determination and include the data in a written report
    (see section 7.8.4 of this document for the information that must be
    included in this report).

    1.  [What performance test requirements do I have to follow if I am
        complying with the CO percent reduction limitation?]{.underline}

If you are complying with the CO percent reduction limit, you must
conduct all of your performance tests using the following criteria
\[Table 4, item 1\].

1.  You must measure the O~2~ at the inlet and outlet of the oxidation
    catalyst or other control device with a portable CO and O~2~
    analyzer, using ASTM D6522-00[^95] (incorporated by reference,
    according to \'63.14). You must make measurements to determine O~2~
    at the same time as the measurements for CO concentration.

2.  You must measure the CO at the inlet and outlet of the oxidation
    catalyst or other control device with a portable CO and O~2~
    analyzer, using ASTM D6522-00[^96] (incorporated by reference,
    according to \'63.14). The CO concentration must be at 15% O~2~, dry
    basis

Determine compliance with the CO percent reduction requirement using the
following set of equations \[\'63.6620(e)\]:

1.  [What performance test requirements do I have to follow if I am
    complying with the formaldehyde concentration
    limitation?]{.underline}

If you are complying with the requirement to limit the formaldehyde
concentration you must conduct your initial and all subsequent
performance tests using the following criteria \[Table 4, item 3\]:

1.  You must select the location of the sampling port and the number of
    traverse points using Method 1 or 1A (40 CFR part 60, appendix A).
    You must choose a sampling site that is located at the outlet of the
    oxidation catalyst or other control device; AND

2.  You must determine the O~2~ concentration of the CI stationary RICE
    exhaust at the sampling port location using Method 3, 3A or 3B (40
    CFR part 60, appendix A). You must take the measurements to
    determine the O~2~ concentration at the same time and location as
    the measurements for the formaldehyde concentration; AND

3.  You must measure the moisture content of the CI stationary RICE
    exhaust at the sampling port location using Method 4 (40 CFR part
    60, appendix A) or Method 320 (40 CFR part 63, appendix A) or ASTM D
    6348-03. You must take measurements to determine the moisture
    content at the same time and location as the measurements for the
    formaldehyde concentration; AND

4.  You must measure formaldehyde at the exhaust of the CI stationary
    RICE using Method 320 or 323 (40 CFR part 60, appendix A), or ASTM
    D6348-03, [^97] provided in ASTM D6348-03 Annex A5 (Analyte Spiking
    Technique), the percent R must be [\>]{.underline} 70 and
    ­[\<]{.underline} 130. You must convert the formaldehyde
    concentration to 15% O~2~, dry basis. Results of this test consist
    of the average of the three 1-hr or longer runs.

    1.  Initial Performance Test

You must conduct an initial performance test for new or reconstructed CI
engines subject to Subpart ZZZZ to show that you are meeting either the
CO percent reduction limit or the formaldehyde concentration limit. The
initial performance test must be conducted using the methods and test
procedures presented in Section 7.2.1.

The results of the initial performance test must show that you have
reduced CO emissions by 70 percent or more or the formaldehyde
concentration in your stationary RICE exhaust is less than or equal to
580 ppbvd at 15 percent O~2~ \[\'63.6630(a)\].

1.  [Measuring Operating Parameters During the Initial Performance
    Test]{.underline}

If you use an oxidation catalyst to comply with MACT, and are NOT using
a CEMS, you must record two operating parameters during the initial
performance test (Table 5, items 1 and 6):

-   pressure drop across the catalyst; and

-   inlet temperature to the catalyst.

If you are not using an oxidation catalyst and EPA has approved your
petition to establish operating limitations, you must record parameters
during the initial performance test in accordance with EPA's approval of
your petition to establish operating limitations (Table 5, items 2 and
7). These values will be used to establish your operating limits (see
Sections 7.3 or 7.4 of this document). Note that you should not conduct
the initial performance test until EPA acts on your petition
\[\'63.6620(f)\].

If you are not using an oxidation catalyst and EPA approved your
petition EPA to establish NO operating limitations, you are not required
to record parameters during the initial performance test. Note that you
should not conduct the initial performance test until EPA acts on your
petition \[\'63.6620(f)\].

1.  [When do I have to conduct the initial performance
    test?]{.underline}

If construction/reconstruction of the new or reconstructed CI stationary
RICE commences after June 15, 2004, you must conduct the initial
compliance test within 180 days after you start up the new or
reconstructed engine \[§63.6610(a)\].

If you have a new or reconstructed CI stationary RICE that commenced
construction (or reconstruction) between December 19, 2002 and June 15,
2004, you have to conduct the initial performance test no later than
February 10, 2005 or no later than 180 days after startup of your
engine, whichever date is later \[§63.6610(b)\].

2.  [When is an initial performance test not required?]{.underline}

You do not have to perform an initial performance test if you have
conducted a performance test on your CI stationary RICE that meets the
following criteria:

1.  The test was conducted using the same test methods specified in
    section 7.2.1.1 or 7.2.1.2 of this document, and you followed these
    methods correctly.

2.  The test is not older than 2 years.

3.  The test has been reviewed and accepted by EPA.

4.  No process or equipment changes have been made since the test was
    performed, or you can demonstrate that the results of the
    performance test, with or without adjustments, reliably demonstrate
    compliance despite process or equipment changes.

5.  The test was conducted at any load condition within
    ­[+]{.underline}10 percent of 100 percent load.

You are also not required to conduct an initial performance test if you
install a CEMS to continuously monitor CO and either O~2~ or CO~2~.
Instead, for each CEMS, you are required to conduct an initial
performance evaluation (see section 7.5 for more details regarding the
performance evaluation). You are required to conduct the initial
performance evaluation for each CEMS by February 12, 2005 or within 180
days after startup, whichever is later.

1.  Semiannual Performance Tests

You must conduct semi-annual performance tests if:

-   You are complying with the CO percent reduction limit AND your CI
    stationary RICE is NOT equipped with a CEMS.

-   You are complying with the formaldehyde concentration limit
    \[\'63.6615 and Table 3\].

If you conduct two consecutive performance tests and are in compliance
with the applicable emission limitation, you may conduct the subsequent
performance tests on an annual basis. You must resume semi-annual tests
if:

-   Any subsequent performance test shows that you are not in compliance
    with your emission limit, or

-   You deviate from any of your operating limitations \[Table 3,
    footnote\].

    1.  Other Required Tests

If you are using a catalyst, such as an oxidation catalyst, to comply
with Subpart ZZZZ, and you change the catalyst, you are required to
conduct a performance test to show that you are meeting the applicable
emission limitation. You must also reestablish the values of the
operating parameters measured during the initial performance test
\[\'63.6640(b)\]. If you are using an oxidation catalyst to comply with
MACT, you must reestablish the initial pressure drop for the catalyst
and measure the inlet temperature to the catalyst during the
catalyst-change performance test.

2.  Reports and Notification for Performance Tests

The reports and notifications required for performance tests are
presented in the table below:

These reports and notifications are discussed further in Sections 7.7
and 7.8.

1.  **What Are The Operating Limits And Parameter Monitoring
    Requirements If I Am Using An Oxidation Catalyst?**

In addition to meeting emission limitations, you may also have to meet
certain operating limits. The operating limits for CI engines are
presented in Table 2b of Subpart ZZZZ. If you choose to install a CEMS,
you do not have operating limits to comply with MACT. Section 7.5
presents your requirements if you choose to install a CEMS.

It is important to note that these operating limits are enforceable
independent of the emission limits -- they are not triggers to assess
your emissions. Instead they are separate and enforceable limits.

This section presents the operating limit and parameter monitoring
requirements if you are using an oxidation catalyst to meet the
applicable CO or formaldehyde emission limit. If you are not using an
oxidation catalyst, section 7.4 presents the operating limit and
parameter monitoring requirements for other control technologies.

The operating limits and parameter monitoring requirements are the same
for both the 70-percent CO percent reduction requirement and the
580-ppbvd formaldehyde concentration requirement.

1.  Operating Limits for CI Engines using Oxidation Catalyst to Comply
    with MACT

Two operating limits apply for CI engines using oxidation catalyst to
comply with MACT:

-   Maintain your catalyst so that the pressure drop across the catalyst
    does not change by more than two inches of water at 100 percent load
    plus or minus 10 percent from the pressure drop across the catalyst
    measured during the initial performance test; and

-   Maintain the temperature of your engine exhaust so that the catalyst
    inlet temperature is greater than or equal to 450F and less than or
    equal to 1350F.

Note that you establish the initial pressure drop across the catalyst
during the initial performance test. The allowable range for pressure
drop is 2" WC from the initial pressure drop. Also note that if you
change your catalyst, you are required to reestablish the initial
pressure drop for the new catalyst element.

As discussed further below, to demonstrate compliance with these
operating limits, you must measure pressure drop across the catalyst
monthly, and you must continuously monitor temperature at the catalyst
inlet (i.e., the stationary RICE exhaust temperature at the catalyst
inlet).

1.  Monthly Pressure Drop Measurements

You demonstrate that you are meeting the pressure drop operating limit
by measuring the pressure drop across the catalyst once a month \[Table
6, items 1 and 7\]. The monthly pressure drop measurements should be
taken while the engine is operating at 100% load 10%.

You are meeting the operating limit if the pressure drop measured each
month is within two inches of water of the pressure drop measured during
the performance test \[Table 2b, item 1\].

2.  Continuous Catalyst Inlet Temperature Monitoring

You are required to install and operate a continuous parameter
monitoring system (CPMS) to measure catalyst inlet temperature \[Table
5, items 1 and 6\]. You must collect the catalyst inlet temperature data
and reduce these data to 4-hour rolling averages \[Table 6, items 1 and
7\].[^98] You are meeting the oxidation catalyst inlet temperature
operating limit if the 4-hour rolling average oxidation catalyst inlet
temperature is greater than or equal to 450^o^F or less than or equal to
1,350^o^F \[Table 2b, item 1\].

3.  Continuous Parameter Monitoring System Requirements

For each stationary RICE, you are required to install a CPMS to
continuously monitor catalyst inlet temperature (Table 5, items 1 and
6). For each CPMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for your CPMS
\[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 7.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^99] you are required to
    take the necessary corrective action and repeat all necessary tests
    which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^100] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 7.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time as the
notification to conduct your performance test.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CPMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance test or performance evaluation is scheduled to
begin, or on a mutually agreed upon date. The Administrator will review
and approve the performance evaluation test plan at the same time as the
review and approval of the site-specific test plan (if review of the
site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Operating Limits and Parameter Monitoring
        Requirements If I am not Using Oxidation Catalyst?**

If you choose to meet the CO or formaldehyde emission limits using a
control technique other than oxidation catalyst, you are required to
petition the Administrator for approval of operating limitations to be
established during the initial performance test. If you feel that no
operating limits are appropriate for your technology, you may also
petition the Administrator for approval of no operating limitations.
Your petition has to receive approval from the Administrator before you
can conduct your initial performance test \[\'63.6620(f)\].

1.  Petition for Approval of Operating Limitations

If you petition the Administrator for approval of operating limitations,
the petition must contain the following information \[\'63.6620(g)\]:

-   You must identify the specific parameters you propose to use as
    operating limitations;

-   You must provide a discussion of the relationship between these
    parameters and HAP emissions, identifying how HAP emissions change
    with changes in these parameters, and how limitations on these
    parameters will serve to limit HAP emissions;

-   You must provide a discussion of how you will establish the upper
    and/or lower values for these parameters which will establish the
    limits on these parameters in the operating limitations;

-   You must provide a discussion identifying the methods you will use
    to measure and the instruments you will use to monitor these
    parameters, as well as the relative accuracy and precision of these
    methods and instruments; and

-   You must provide a discussion identifying the frequency and methods
    for recalibrating the instruments you will use for monitoring these
    parameters.

    1.  Petition for Approval of No Operating Limitations

If you petition the Administrator for approval of no operating
limitations, your petition must include the following information
\[\'63.6620(h)\]:

-   You must identify the parameters associated with operation of the
    stationary RICE and the emission control device which could change
    intentionally (e.g., operator adjustment, automatic controller
    adjustment, etc.) or unintentionally (e.g., wear and tear, error,
    etc.) on a routine basis or over time;

-   You must provide a discussion of the relationship, if any, between
    changes in the parameters and changes in HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of whether establishing
    limitations on the parameters would serve to limit HAP emissions;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion of how you could
    establish upper and/or lower values for the parameters which would
    establish limits on the parameters in operating limitations;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the methods
    you could use to measure them and the instruments you could use to
    monitor them, as well as the relative accuracy and precision of the
    methods and instruments;

-   For the parameters which could change in such a way as to increase
    HAP emissions, you must provide a discussion identifying the
    frequency and methods for recalibrating the instruments you could
    use to monitor them; and

```{=html}
<!-- -->
```
-   You must provide a discussion of why, from your point of view, it is
    infeasible or unreasonable to adopt the parameters as operating
    limitations.

    1.  Continuous Parameter Monitoring System Requirements

If you have petitioned the Administrator for operating limitations, for
each stationary RICE you are required to install a continuous parameter
monitoring system (CPMS) to continuously monitor your approved operating
parameters. For each CPMS, you are required to follow certain operation
and maintenance requirements; prepare a quality control program; and
conduct performance evaluations.

1.  [Operation and maintenance requirements for CPMS]{.underline}

There are several operation and maintenance requirements for operation
of your CPMS \[\'63.8(c)\]:

-   You must operate the CPMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CPMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CPMS (see section 7.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CPMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CPMS operational and have the data
    verified before or at the time of the initial performance test (you
    verify the operational status of your CPMS by, at a minimum,
    completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CPMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   You must calibrate the CPMS prior to use;

-   You must check each CPMS daily for indication that the system is
    responding;

-   If the CPMS has an internal system check, you must record and check
    the results on a daily basis for proper operation;

-   If you have a CPMS that is out of control, [^101] you are required
    to take the necessary corrective action and repeat all necessary
    tests which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CPMS is out of control
    in data averages or calculations.

-   If you have a CPMS that is out of control,[^102] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 7.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CPMS \[\'63.8(d)\]. The program must contain a written protocol
that describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CPMS;

-   Determination and adjustment of the calibration drift of the CPMS;

-   Preventive maintenance of the CPMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CPMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CPMS
\[\'63.8(e)\]. You must conduct the performance evaluation on your CPMS
during the initial performance test required under the RICE MACT. You
are required to notify the Administrator in writing of the date that you
are going to conduct your performance evaluation at the same time you
submit the notification to conduct your performance test. If you are not
conducting a performance test, the performance evaluation notification
must be submitted at least 60 days prior to the date that you are
scheduled to begin the performance evaluation.

Before conducting the performance evaluation, you may be required to
develop and submit a site-specific performance evaluation test plan to
the Administrator for approval. The following elements must be included
in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

If the Administrator requests that you submit a site-specific
performance evaluation test plan for approval, it is due at least 60
days before the performance test or performance evaluation is scheduled
to begin, or on a mutually agreed upon date. The Administrator will
review and approve the performance evaluation test plan at the same time
as the review and approval of the site-specific test plan (if review of
the site-specific test plan is requested). The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation at the same time as the performance test
    using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently chooses to use the
    specified monitoring method(s) instead of an alternative.

    1.  Requirements for Approved Operating Limits

You are required to install and operate a CPMS to measure your approved
operating limit \[Table 5, items 2 and 7\]. You must collect the
parameter data you approved by the Administrator and reduce these data
to 4-hour rolling averages \[Table 6, items 2 and 8\].[^103] You are
meeting the approved operating limit if the 4-hour rolling average
parameter data is within your approved operating limitations for the
operating parameters established during the initial performance test.

1.  **What are the Monitoring Requirements If I am using a CEMS?**

If you are complying with the CO percent reduction emission limitation,
you have the option of installing a CEMS to demonstrate that you are
reducing CO by 70 percent or more. You may choose this option for any
control technique. You must install a CEMS to continuously monitor CO
and either oxygen or CO~2~ at both the inlet and outlet of the control
device according to the following \[§63.6625(a)\]:

-   You must install, operate and maintain each CEMS as specified in
    performance specifications (PS) 3 and 4A of 40 CFR part 60, appendix
    B.

-   You must conduct an initial performance evaluation and an annual
    relative accuracy test audit (RATA) according to \'63.8 and PS 3 and
    4 (40 CFR part 60, appendix B).

-   You must conduct daily and periodic data quality checks specified in
    40 CFR part 60, appendix F, procedure 1.

-   You must install the CEMS such that a minimum of one cycle of
    operation (sampling, analyzing, and data recording) is completed for
    each successive 15-minute period. There must be two data points,
    with each representing a different 15-minute period, to have a valid
    hour of data.

-   You must reduce the CEMS data to 1-hour averages computed from four
    or more data points equally spaced over each 1-hour period, except
    during periods when calibration, quality assurance, or maintenance
    activities are being performed. During these periods, an hourly
    average is considered valid if you have at least two data points,
    each representing a 15-minute period. NOTE: You may also use an
    arithmetic or integrated 1-hour average of CEMS data.

-   You must also keep records of the reduced data in parts per million
    at 15 percent oxygen or the equivalent CO~2~ concentration.

    1.  Initial Performance Evaluation Requirements

For each CEMS, you must conduct an initial performance evaluation and an
initial RATA using the procedures specified in §63.8 and PS 3 (for
oxygen or CO~2~) and 4A (for CO) of 40 CFR part 60, appendix B. You are
not required to conduct the performance tests specified in Table 4. The
initial performance evaluation must be conducted by February 12, 2005 or
within 180 days after startup of your new or reconstructed stationary
RICE, whichever date is later.

Once the performance evaluation has been completed you must calculate
the average CO percent reduction. This calculation is based on the first
four hours of monitoring data collected once the CEMS has been
successfully validated \[Table 5, item 3.a.iii\].

Determine compliance with the CO percent reduction requirement using the
following set of equations \[\'63.6620(e)\]:

2.  Additional Requirements

You are required to conduct annual RATA of each CEMS using PS 3 (for
oxygen or CO~2~) and PS 4A (for CO) \[40 CFR part 60, appendix B\], as
well as the daily and periodic data quality checks specified in 40 CFR
part 60, appendix F, procedure 1.

You must collect monitoring data (see section 7.5.3 for specific
monitoring installation, operation, and maintenance requirements) and
reduce the measurements to one-hour averages and calculate the percent
reduction of CO emissions using the formulas presented in section 7.5.1.
You must collect the one-hour average CO percent reduction data and
reduce these data to 4-hour rolling averages \[Table 6, item 3\].[^104]
You are meeting the CO percent reduction emission limit if the 4-hour
rolling average CO percent reduction is greater than or equal to 70
percent.

3.  Continuous Emission Monitoring System Requirements

For each CEMS, you are required to follow certain operation and
maintenance requirements; prepare a quality control program; and conduct
performance evaluations.

1.  [Operation and maintenance requirements for CEMS]{.underline}

There are several operation and maintenance requirements for your CEMS
\[§63.8(c)\]:

-   You must operate the CEMS at all times, including during periods of
    startup, shutdown, or malfunction;

-   You must have the necessary parts for routine repairs of the CEMS
    readily available;

-   You must develop a written startup, shutdown, and malfunction (SSM)
    plan for CEMS (see section 7.6 of this document for specific SSM
    plan requirements);

-   The read-out (i.e., visual display or record), or some indication of
    operation, from your CEMS must be readily accessible for control or
    inspection by the equipment operator;

-   You must install and have the CEMS operational and have the data
    verified either prior to or during the initial performance
    evaluation (you verify the operational status of your CEMS by, at a
    minimum, completing the manufacturer's written specifications or
    recommendations for installation, operation and calibration of the
    system);

-   You must operate the CEMS continuously except for system breakdowns,
    out-of-control periods, repairs, maintenance periods, calibration
    checks, and zero (low-level) and high-level calibration drift
    adjustments;

-   Each CEMS must complete a minimum of one cycle of operation (i.e.,
    sampling, analyzing, and data recording) for each successive
    15-minute period;

-   You must check the zero (low-level) and high-level calibration
    drifts of each CEMS installed according to PS 3 (for oxygen or
    CO~2~) or PS 4A (for CO) at least once daily according to your
    performance evaluation plan (see section 7.5.1.3). You must adjust
    the zero (low-level) and high-level calibration drifts, at a
    minimum, whenever the 24-hour zero (low-level) drift exceeds two
    times the limits specified in the PS. The system must allow the
    amount of excess zero (low-level) and high-level drift measured at
    the 24-hour interval checks to be recorded and quantified whenever
    specified.

-   If you have a CEMS that is out of control, [^105] you are required
    to take the necessary corrective action and repeat all necessary
    tests which indicate that the system is out of control. You also are
    required to take corrective actions and conduct retesting until the
    performance requirements are below the applicable limits. You may
    not use data recorded during periods that the CEMS is out of control
    in data averages or calculations.

-   If you have a CEMS that is out of control,[^106] you have to submit
    all information concerning out-of-control periods, including start
    and end dates, hours, and descriptions of your corrective actions in
    the semiannual compliance report (see section 7.8 of this document
    for more details on this report).

    1.  [Quality Control Program]{.underline}

You are required to develop and implement a quality control program for
your CEMS \[§63.8(d)\]. The program must contain a written protocol that
describes the procedures for the following operations:

-   Initial and any subsequent calibration of the CEMS;

-   Determination and adjustment of the calibration drift of the CEMS;

-   Preventive maintenance of the CEMS, including spare parts inventory;

-   Data recording, calculations, and reporting;

-   Accuracy audit procedures, including sampling and analysis methods;
    and

-   Program of corrective action for a malfunctioning CEMS.

You are required to maintain these written procedures on record for the
life of the stationary RICE or until your stationary RICE is no longer
subject to the RICE MACT. If appropriate, you may incorporate these
written procedures as part of your SSM plan to avoid duplicating
planning and recordkeeping efforts.

1.  [Performance Evaluation]{.underline}

You are required to conduct a performance evaluation for each CEMS
\[§63.8(e)\]. You must conduct this performance evaluation by February
12, 2005 or within 180 days after startup, whichever is later. You are
required to notify the Administrator in writing of the date that you are
going to conduct your performance evaluation at least 60 days before the
performance evaluation is scheduled to begin.

Before conducting the performance evaluation, you must prepare a
site-specific performance evaluation test plan. The following elements
must be included in the test plan:

-   the evaluation program objectives;

-   an evaluation program summary;

-   the performance evaluation schedule;

-   data quality objectives (the pre-evaluation expectations of
    precision, accuracy, and completeness of data);

-   an internal QA program, which must include, at a minimum, the
    activities planned by routine operators and analysts to provide an
    assessment of CEMS performance; and

-   an external QA program which must include, at a minimum, systems
    audits that include the opportunity for on-site evaluation by the
    Administrator of instrument calibration, data validation, sample
    logging, and documentation of quality control data and field
    maintenance activities.

You must submit the performance evaluation test plan ONLY if requested
by EPA or the delegated authority. If requested, the site-specific
performance evaluation test plan must be submitted at least 60 days
before the performance evaluation is scheduled to begin, or on a
mutually agreed upon date. The Administrator will review and approve the
performance evaluation test plan. The Administrator may request
additional relevant information after the submittal of a site-specific
performance evaluation test plan.

If the Administrator fails to approve or disapprove the site-specific
performance evaluation test plan within the 30 calendar days after
receipt of the test plan, the following conditions apply:

-   If you intend to demonstrate compliance using the monitoring
    method(s) specified in the RICE MACT, you are required to conduct
    the performance evaluation using the specified method(s);

-   If you intend to demonstrate compliance by using an alternative
    monitoring method, you must not conduct the performance evaluation
    until the Administrator approves the use of the alternative method.
    If the Administrator does not approve the alternative method within
    30 days before the performance evaluation is scheduled to begin, the
    performance evaluation deadlines may be extended such that you must
    conduct the performance evaluation within 60 calendar days after the
    Administrator approves the use of the alternative method. You may
    proceed to conduct the performance evaluation (without the
    Administrator\'s prior approval of the site-specific performance
    evaluation test plan) if you subsequently choose to use the
    specified monitoring method(s) instead of an alternative.

    1.  **What are the Startup, Shutdown, and Malfunction (SSM)
        Requirements?**

You are required to operate your oxidation catalyst or other control
device as well as any CPMS or CEMS at all times, including periods of
startup, shutdown, and malfunction (SSM), in a safe manner and according
to good air pollution control practices to minimize emissions.

A startup is defined as "the setting in operation of an affected source
or portion of an affected source for any purpose." \[§63.2\]

A shutdown is defined as "the cessation of operation of an affected
source or portion of an affected source for any purpose." \[§63.2\]

A malfunction is defined as "any sudden, infrequent, and not reasonably
preventable failure of air pollution control and monitoring equipment,
process equipment, or a process to operate in a normal or usual manner
which causes, or has the potential to cause, the emission limitations in
an applicable standard to be exceeded. Failures that are caused in part
by poor maintenance or careless operation are not malfunctions."
\[§63.2\]

1.  What are my requirements during SSM events?

You are responsible for reducing emissions to the greatest extent
possible and maintain safety and good air control practices whenever
there is a period of SSM. This does not mean that you are required to
achieve the emission levels required under the RICE MACT during SSM
events if it means that you would not be operating in a safe manner and
with good air pollution practices nor are you required to make any
further efforts to reduce emissions if you are meeting the emission
levels required by the RICE MACT.

2.  Startup, Shutdown and Malfunction Plan

You are required to develop and implement a written startup, shutdown,
and malfunction (SSM) plan that describes, in detail, procedures for
operating and maintaining the each stationary RICE during periods of
SSM, and a program of corrective action for malfunctioning process and
air pollution control and monitoring equipment (i.e., oxidation catalyst
or other control device, pressure drop monitoring equipment, and CPMS or
CEMS). You must develop this plan by August 16, 2004 if construction or
reconstruction of your new or reconstructed stationary RICE commenced on
or after December 19, 2002 but before August 16, 2004. If construction
or reconstruction of your new or reconstructed stationary RICE began
after August 16, 2004, you must have your SSM plan developed by startup
\[§63.6(e)(3)(i)\].

During periods of SSM, you must operate and maintain your stationary
RICE (including each oxidation catalyst or other control device and
monitoring equipment) in accordance with the procedures specified in
your SSM plan \[§63.6(e)(3)(ii)\].

1.  [What must be included in my SSM plan?]{.underline}

EPA does not specify the required elements of a SSM plan, but the SSM
plan must address the following \[§63.6(e)(3)(i)(A) through (C)\]:

1.  Ensure that, at all times, you operate and maintain each stationary
    RICE, including your oxidation catalyst or other control device and
    monitoring equipment, in a manner which satisfies your general duty
    to minimize emissions;

2.  Ensure that you are prepared to correct malfunctions as soon as
    practicable after their occurrence in order to minimize excess
    emissions of hazardous air pollutants; and

3.  Reduce the reporting burden associated with periods of startup,
    shutdown, and malfunction (including corrective action taken to
    restore malfunctioning process and air pollution control equipment
    to its normal or usual manner of operation).

To develop your SSM plan, you may use your standard operating procedures
(SOP) manual, or an Occupational Safety and Health Administration (OSHA)
or other plan, provided the alternative plans meet the SSM plan
requirements and are made available for inspection or submitted when
requested by EPA or the delegated authority \[§63.6(e)(3)(vi)\].

1.  [When may the SSM plan be revised?]{.underline}

You may periodically revise the SSM plan for your stationary RICE as
necessary to satisfy the requirements of 40 CFR part 63 or to reflect
changes in equipment or procedures at the affected source. Unless EPA or
your permitting authority provides otherwise, you may make such
revisions to the startup, shutdown, and malfunction plan without prior
approval by EPA or the permitting authority \[§63.6(e)(3)(viii)\].
However, each revision to a SSM plan must be reported in the semiannual
compliance report (see section 7.8.6).

If the SSM plan fails to address or inadequately addresses an event that
meets the characteristics of a malfunction but was not included in the
SSM plan at the time you developed the plan, you must revise the SSM
plan within 45 days after the event to include detailed procedures for
operating and maintaining the source during similar malfunction events
and a program of corrective action for similar malfunctions of process
or air pollution control and monitoring equipment \[§63.6(e)(3)(viii)\].

In the event that you make any revision to the SSM plan which alters the
scope of the activities which are deemed to be an SSM, or otherwise
modify the applicability of any emission limit or other RICE MACT
requirement, the revised plan may not take effect until after you have
provided a written notice describing the revision to your permitting
authority \[§63.6(e)(3)(viii)\].

If EPA or the delegated authority determines that you are not operating
and maintaining your stationary RICE (including the oxidation catalyst
or other control device and monitoring equipment) in such a way that is
consistent with safety and good air pollution control practices
\[§63.6(e)(1)(i)\], EPA or the delegated authority may require you to
make changes to the SSM plan for that stationary RICE. EPA or the
delegated authority must require appropriate revisions to a SSM plan, if
EPA or the delegated authority finds that the plan \[§63.6(e)(3)(vii)\]:

-   Does not address a SSM event that has occurred;

-   Fails to provide for the operation of the stationary RICE (including
    the oxidation catalyst or other control device and monitoring
    equipment) during a SSM event in a manner consistent with the
    general duty to minimize emissions established by §63.6(e)(1)(i);

-   Does not provide adequate procedures for correcting malfunctioning
    process and/or air pollution control and monitoring equipment as
    quickly as practicable; or

-   Includes an event that does not meet the definition of startup,
    shutdown, or malfunction listed in §63.2.

The title V permit for a stationary RICE must require that you adopt a
SSM plan which conforms to part 63, and that you operate and maintain
the stationary in accordance with the procedures specified in the
current SSM plan. However, any revisions made to the SSM plan as
specified above do not constitute permit revisions under part 70 or part
71 of this chapter. Moreover, none of the procedures specified by the
SSM plan for an affected source shall be deemed to fall within the
permit shield provision in section 504(f) of the Act
\[§63.6(e)(3)(ix)\].

1.  [What are my requirements for maintaining my SSM plan?]{.underline}

You must maintain a current SSM plan and must make the plan available
upon request for inspection and copying by the EPA or delegated
authority. In addition, if you subsequently revise your SSM plan (see
section 7.6.2.2), you must keep each previous (i.e., superseded) version
of the SSM plan, and must make each such previous version available for
inspection and copying by the EPA or the delegated authority for 5 years
after revision of the plan. If at any time after adoption of an SSM plan
the stationary RICE ceases operation or is otherwise no longer subject
to the RICE MACT, you must keep a copy of the most recent plan for 5
years from the date the stationary RICE ceases operation or is no longer
subject the RICE MACT and must make the plan available upon request for
inspection and copying by EPA or the delegated authority
\[§63.6(e)(3)(v)\].

EPA or the delegated authority may at any time request in writing that
you submit a copy of any SSM plan (or a portion thereof). Upon receipt
of such a request, you must promptly submit a copy of the requested plan
(or a portion thereof) to EPA or the delegated authority. EPA or the
delegated authority must request that you submit a particular SSM plan
(or a portion thereof) whenever a member of the public submits a
specific and reasonable request to examine or to receive a copy of that
plan or portion of a plan. You may elect to submit the required copy of
any SSM plan in an electronic format. If you claim that any portion of
such a SSM plan is confidential business information entitled to
protection from disclosure under section 114(c) of the Act or 40 CFR
2.301, the material which is claimed as confidential must be clearly
designated in the submission. \[§63.6(e)(3)(v)\]

1.  How do I demonstrate I am following my SSM plan?

When you take actions during a period of SSM (including actions taken to
correct a malfunction) that are consistent with the procedures specified
in the SSM plan developed for your stationary RICE, you must do the
following \[§63.6(e)(iii)\]:

-   You must keep records for that event which demonstrate that the
    procedures specified in the plan were followed. These records may
    take the form of a "checklist," or other form of recordkeeping that
    confirms that you followed the procedures defined in your SSM plan
    for that event.

-   You must keep the following records of these events
    \[§63.10(b)(2)\]:

    -   Records of the occurrence and duration of each startup,
        shutdown, or malfunction of operation

    -   Records of the occurrence and duration of each malfunction of
        the oxidation catalyst or other control device and monitoring
        equipment

-   You must confirm that actions taken during the relevant reporting
    period during periods of SSM were consistent with the startup,
    shutdown and malfunction plan developed for each stationary RICE in
    the semiannual (or more frequent) startup, shutdown, and malfunction
    report required in §63.10(d)(5). Note that this information may also
    be incorporated into your semiannual compliance report (see section
    7.8.6).

If you take an action during a startup, shutdown, or malfunction
(including an action taken to correct a malfunction) that is not
consistent with the procedures specified in your stationary RICE\'s
startup, shutdown, and malfunction plan, and the stationary RICE exceeds
the applicable emission limitation, then you must record the actions
taken for that event and must report such actions within 2 working days
after commencing actions inconsistent with the plan, followed by a
letter within 7 working days after the end of the event, in accordance
with §63.10(d)(5) (unless the owner or operator makes alternative
reporting arrangements, in advance, with the Administrator)
\[§63.6(e)(3)(iv)\].

1.  **What Records Must I Keep?**

You are required to keep records of activities required to meet the
final RICE MACT. You must keep files of all information (including
reports and notifications) required under the RICE MACT in a format
suitable and readily available for "expeditious inspection and review
\[\'63.6660(a)\]." You must maintain these records for 5 years following
the date of each occurrence, measurement, maintenance, corrective
action, report, or record \[\'63.6660(b)\]. Records may be kept in hard
copy or electronic form. You may retain at least 2 years of records
on-site. You can keep records off-site for the remaining 3 years
\[\'63.6660(c)\].

1.  Recordkeeping Requirements for Notifications and Reports

You are required to keep a copy of each notification and report that you
have submitted as a part of complying with the RICE MACT, including all
documentation supporting any notification or report \[\'63.6655(a)(1)\].
You must maintain records of the following notifications and reports
(see section 7.8 of this document for details regarding these
notifications and reports):

-   Initial Notification;

-   Notifications of performance tests;

-   Site-specific test plan;

-   Notification of performance evaluation for continuous monitoring
    systems (CMS), including both CPMS and CEMS;

-   Site-specific performance evaluation plan(s);

-   Any request to use an alternative monitoring procedure;

-   Any request for extension of compliance;

-   Notification that your source is subject to special compliance
    requirements;

-   Notification of compliance status, including performance test
    results and written report to document engine load conditions during
    the test;

-   Semiannual compliance reports; and

-   Startup, shutdown, and malfunction reports.

    1.  Recordkeeping Requirements for Startup, Shutdown, and
        Malfunction Events

You are required to keep records related to startup, shutdown and
malfunction (SSM) events as follows (see section 7.6 for details on SSM
events) \[\'\'63.6655(a)(2) and 63.6(e)(3)(iii) through (v):

-   When you take actions during an SSM event (including actions taken
    to correct a malfunction), that are consistent with the procedures
    specified your SSM plan, you must keep records which demonstrate
    that the procedures specified in the plan were followed. You may
    keep records in the form of a "checklist," or you may choose another
    form of recordkeeping that documents that you have followed your SSM
    plan for that event.

-   You must keep records of these SSM events, including records of the
    occurrence and duration of each startup, shutdown, or malfunction of
    operation and each malfunction of the air pollution control and
    monitoring equipment.

-   When you take actions during an SSM event that are not consistent
    with the procedures specified in the your SSM plan, and the
    stationary RICE exceeds the formaldehyde emission limitations, then
    you must record the actions taken for that event.

-   You must maintain a current SSM plan and must make the plan
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your SSM plan, you are
    required to keep a copy of each previous (i.e., superseded) version
    of the SSM plan for 5 years after each revision. Previous versions
    must be available for inspection and copying by the Administrator.

-   If at any time after adoption of a SSM plan stationary RICE ceases
    operation or is otherwise no longer subject to the RICE MACT, you
    must retain a copy of the most recent plan for 5 years from the date
    the stationary RICE ceases operation or is no longer subject to the
    RICE MACT. This plan must be available upon request for inspection
    and copying by the Administrator.

-   The Administrator may request in writing that you submit a copy of
    any SSM plan (or portion of the plan). Upon receipt of such a
    request, you must promptly submit a copy of the requested plan (or
    portion of the plan) to the Administrator. The Administrator is
    required to request that you submit a particular SSM plan (or a
    portion thereof) whenever a member of the public submits a specific
    and reasonable request to examine or to receive a copy of that plan
    or portion of a plan. You may elect to submit the required copy of
    any SSM plan to the Administrator in an electronic format. If you
    claim that any portion of such a SSM plan is confidential business
    information entitled to protection from disclosure under section
    114(c) of the Act or 40 CFR 2.301, the material which is claimed as
    confidential must be clearly designated in the submission.

    1.  Recordkeeping Requirements for Performance Tests and CMS

You are required to keep records of all performance test and performance
evaluation results. Performance test results may include analysis of
samples, determination of emissions, and raw data \[\'\'63.6655(b) and
63.10(b)(2)(viii)\].

For each CMS (this includes CPMS and CEMS), you are required to keep the
following records \[\'\'63.6655(b) and 63.10(b)(2)(vi) through (xi)\]:

-   All CMS performance evaluations;

-   Records of each period during which the CMS is malfunctioning or
    inoperative (including periods where the CMS is out of control);

-   All required measurements needed to demonstrate compliance with the
    operating limitations or the CO percent reduction emission
    limitation (including, but not limited to, 15-minute averages of
    CPMS data, raw performance testing measurements, and raw performance
    evaluation measurements, that support data that you are required to
    report);

    -   For each CEMS that is automated[^107] and where the calculated
        data averages do not exclude periods of CEMS breakdowns or
        malfunction, rather than maintain a file of all CEMS subhourly
        measurements, you must retain the most recent consecutive three
        averaging periods of subhourly measurements and a file that
        contains a hard copy of the data acquisition system algorithm
        used to reduce the measured data into the reportable form of the
        standard.

    -   For each CEMS where measured data is manually reduced to the
        form of the emission limit, and where calculated data averages
        do not exclude periods of CEMS breakdowns or malfunctions,
        rather than maintain a file of all CEMS subhourly measurements,
        you must retain all subhourly measurements for the most recent
        reporting period. You must retain the subhourly measurements for
        120 days from the date of the most recent semiannual compliance
        report submitted to EPA.

    -   EPA or the delegated authority MAY require you to maintain all
        subhourly records if it is determined that these records are
        required to more accurately assess the compliance status of your
        stationary RICE. You will be notified of this requirement

-   All measurements as may be necessary to determine the conditions of
    performance tests and performance evaluations;

-   All CMS calibration checks;

-   All adjustments and maintenance performed on CMS;

-   You must maintain a current performance evaluation test plan and
    quality control procedures and must make these written procedures
    available upon request for inspection and copying by the
    Administrator. If you make revisions to your performance evaluation
    plan, you are required to keep a copy of each previous (i.e.,
    superseded) version of the plan for 5 years after each revision
    \[\'63.8(d)(3)\]. Previous versions must be available for inspection
    and copying by the Administrator. If it is relevant, you may
    incorporate these procedures as part of your SSM plan.

You are also required to keep records of the following \[§63.10(c)(1)
through (14)\]:

-   All required CMS measurements (including monitoring data recorded
    during unavoidable CMS breakdowns and out-of-control periods);

-   The date and time identifying each period during which the CMS was
    inoperative except for zero (low-level) and high-level checks;

-   The date and time identifying each period during which the CMS was
    out of control;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during startups, shutdowns, and
    malfunctions;

-   The specific identification (i.e., date and time of commencement and
    completion) of each period of excess emissions and parameter
    monitoring exceedances that occurs during periods other than
    startups, shutdowns, and malfunctions;

-   The nature and cause (if known) of any malfunction;[^108]

-   The corrective action taken or preventative measures adopted;[^109]

-   The nature of the repairs or adjustments to the CMS that was
    inoperative or out of control;[^110]

-   The total process operating time during the reporting period; and

-   All procedures that are a part of a quality control program and
    implemented for CMS under §63.8(d).

    1.  Recordkeeping Requirements for Monitoring Data

You are required to keep records of all monitoring data you collect to
demonstrate compliance with your operating limitations \[Table 6, items
1, 2, 7, and 8\] or emission limitation \[Table 6, item 3\].

If you are using an oxidation catalyst you must keep records of the
catalyst inlet temperature data measured by your CPMS and the monthly
pressure drop measurements. If you are not using an oxidation, you are
required to keep records of the approved operating parameter. If you are
using a CEMS you are required to keep records of CO and oxygen or CO~2~
data measured by your CEMS.

1.  **What Notifications and Reports Must I Submit?**

For each notification and report, you send a copy to both your State Air
Pollution Control Office and your EPA Regional Office. Appendix B
contains a list of Regional EPA offices and addresses.

1.  Initial Notification

The initial notification states that your affected source is subject to
the RICE standards. If you have a new or reconstructed CI engine that
you startup before August 16, 2004 you are required to submit the

**Instructions**

**Question 1. Facility Information \[40 CFR §63.9(b)(2)(i)and (ii)\]**

This question is self-explanatory --include the name and address,
including physical location, if different, of the facility.

**Question 2. Is The Facility a Major Source? \[40 CFR
§63.9(b)(2)(v)\]**

You are a major source if your plant site emits or has the potential to
emit 10 tons per year (tpy) of one HAP or 25 tpy of any combination of
HAP \[§63.6585(b)\]. Most RICE or groups of RICE are not major HAP
emissions sources by themselves but are located at major HAP sites. Note
that a facility is considered "major" for HAP emissions, regardless of
the contribution from the RICE alone. Further, you must include all RICE
at your facility in this calculation, not just RICE with site-rated
horsepower greater than 500.

When calculating the potential to emit, include all HAP emission sources
located within the contiguous area and under common control, not just
RICE. However, the RICE MACT has special considerations for determining
major source status of oil and gas production and natural gas
transmission and storage facilities \[§63.6585(b)\].

1.  Do not add together emissions from any oil or gas exploration or
    production well (with its associated equipment[^111]) and emissions
    from any pipeline compressor station or pump station with emissions
    from other similar units, even when emission points are in a
    contiguous area or under common control.

2.  For oil and gas production facilities, do not add together emissions
    from processes, operations, or equipment that are not part of the
    same oil and gas production facility.[^112]

3.  For production field facilities, only HAP emissions from glycol
    dehydration units, storage vessel with the potential for flash
    emissions, combustion turbines and RICE need to be added together.

4.  Do not add together emissions from processes, operations, and
    equipment that are not part of the same natural gas transmission and
    storage facility.[^113]

To determine the potential to emit, follow these steps:

1.  Identify all sources of emissions considering the oil and natural
    gas provisions listed above, if applicable.

2.  Identify all HAP that your plant site emits.

3.  Select a method to use to determine your HAP emissions.

4.  For each HAP, determine the maximum amount that each production
    process or piece of equipment in your plant site can emit in one
    year. Use one of the following:

    a.  Your RICE (or other process) operates 24 hours per day, 7 days
        per week, 365 days per year without control.

    b.  If you have federally enforceable[^114] restrictions that affect
        emissions (for example, hours of operations, the presence of a
        control device, or the type of fuel used) you may include the
        effect that these restrictions have on emissions in your
        potential-to-emit calculations.

    c.  *Oil and natural gas production facilities* \[§63.6675\]:
        Potential-to-emit is calculated using the maximum natural gas or
        hydrocarbon liquid throughput for an oil and natural gas
        production facility. You may choose from one of the following
        methods to determine your maximum natural gas or hydrocarbon
        liquid \[§63.760(a)\]:

        i.  If you can show a decline in annual natural gas or
            hydrocarbon liquid throughput (whichever is appropriate) for
            the five years prior to June 17, 1999, your maximum annual
            natural gas or hydrocarbon liquid throughput is the average
            annual natural gas or hydrocarbon liquid throughput for the
            three years prior to June 17, 1999 times 1.2.[^115]

        ii. If you cannot show a decline in annual natural gas or
            hydrocarbon liquid throughput (whichever is appropriate) for
            the five years prior to June 17, 1999, your maximum annual
            natural gas or hydrocarbon liquid throughput is the highest
            annual natural gas or hydrocarbon liquid throughput over the
            five years prior to June 17, 1999 times 1.2. [^116]

        iii. You may use your facility's design maximum natural gas or
             hydrocarbon liquid throughput to estimate potential-to-emit
             for your facility.

        iv. You must determine the maximum values for other parameters
            used to estimate potential-to-emit as the maximum for the
            same period of time you determined your maximum natural gas
            or hydrocarbon liquid throughput above. You must base these
            parameters on an annual average or the highest single
            measured value.

    d.  *Natural gas transmission and storage facilities* \[§63.6675\].
        Potential-to-emit is calculated using the maximum natural gas
        throughput for a natural gas transmission and storage facility.
        You may choose from one of the following methods to determine
        your maximum natural gas throughput \[§63.1270(a)(1) and (2)\]:

        i.  If your facility stores natural gas, you may choose to
            calculate maximum annual natural gas throughput using the
            following equation: [^117]

> $$\text{Throughput} = \frac{8,\text{760}}{\left( \frac{1}{\text{IR}_{\text{max}}}\  + \ \frac{1}{\text{WR}_{\text{max}}} \right)}$$
>
> Where:
>
> Throughput = Maximum annual facilitywide natural gas throughput in
> cubic meters per year.
>
> IR~max~ = Maximum facility injection rate in cubic meters per hour.
>
> WR~max~ = Maximum facility withdrawal rate in cubic meters per hour.
>
> 8,760 = Maximum hours of operation per year.

ii. If your facility only transports natural gas, you may calculate
    maximum annual natural gas throughput as the highest annual natural
    gas throughput over the five years prior to June 17, 1999 times
    1.2.[^118]

iii. You may use your facility's design maximum natural gas throughput
     to estimate potential-to-emit for your facility.

iv. You must determine the maximum values for other parameters used to
    estimate potential-to-emit as the maximum for the same period of
    time you determined your maximum natural gas throughput above. You
    must base these parameters on an annual average or the highest
    single measured value.

    equipment.

Since Subpart ZZZZ only applies to major sources, true minors or area
sources do not need to complete and submit this form. Similarly, if you
have obtained a synthetic minor permit, you would be a minor source not
subject to this NESHAP. However, if you are in the process of obtaining
a synthetic minor permit, please include the relevant information at
Question 2a.

**Question 2a. Synthetic Minor Sources**

EPA policy provides owners/operators with the opportunity to avoid a
standard through a limit on its potential to emit, if federally
enforceable permit limits are in place (i.e., approved by the delegated
authority) prior to the compliance date of the standard.[^119] This
question is intended to notify the delegated authority that a major
source facility is seeking federally enforceable permit limits to avoid
subpart ZZZZ by becoming a "synthetic minor source" (i.e., potential to
emit is less than 10 tpy of any one HAP or 25 tpy of total HAP).
Owners/operators of facilities with existing 4SRB engines may reduce
total potential emissions at the facility and qualify as a "synthetic
minor source" at any time before June 15, 2007, so that the existing
4SRB engines will not be subject to subpart ZZZZ. Owners/operators of
facilities with new or reconstructed engines may reduce total potential
emissions at the facility and qualify as a "synthetic minor source" up
until August 16, 2004 or the startup date of the new or reconstructed
engines, whichever is later, so that the new or reconstructed engines
will not be subject to subpart ZZZZ.

**Question 3. Identification of Relevant Source Categories (40 CFR
§63.9(b)(2)(iii))**

Complete the table for each stationary RICE required to submit an
initial notification. The following definitions are provided to assist
with in completing question 3.

*[Existing/New/Reconstructed]{.underline}*

You are considered an **existing stationary RICE** if you commenced
construction before December 19, 2002.

You are considered a **new or reconstructed stationary RICE** if you
commenced construction or reconstruction on or after December 19, 2002.

You are considered a **reconstructed stationary RICE** if modifications
meet the definition or reconstruction as follows:

> *[Reconstruction]{.underline},* unless otherwise defined in a relevant
> standard, means the replacement of components of an affected or a
> previously nonaffected source to such an extent that:
>
> \(1\) The fixed capital cost of the new components exceeds 50 percent
> of the fixed capital cost that would be required to construct a
> comparable new source; and
>
> \(2\) It is technologically and economically feasible for the
> reconstructed source to meet the relevant standard(s) established by
> the Administrator (or a State) pursuant to section 112 of the Act.
> Upon reconstruction, an affected source, or a stationary source that
> becomes an affected source, is subject to relevant standards for new
> sources, including compliance dates, irrespective of any change in
> emissions of hazardous air pollutants from that source.

*[Subcategories \[\'63.6675\]]{.underline}*

Choose one of the following engine subcategories:

1.  **Emergency Stationary RICE**: An emergency stationary RICE is any
    stationary RICE that operates in an emergency situation. Emergency
    situations include the production of power for critical networks or
    equipment when electric power from the local utility is interrupted,
    as well as pumping water in the case of fire or flood \[§63.6675\].
    Stationary RICE that operate in an emergency situation are
    considered emergency stationary RICE, provided the following
    criteria are met:

-   emergency stationary RICE may be operated to perform maintenance
    checks and readiness testing, provided these tests are recommended
    by the manufacturer, vendor or insurance company associated with the
    engine.

-   there is no limit on the use of an emergency stationary RICE in
    emergency situations and for routine testing and maintenance, but
    testing should be minimized.

-   emergency stationary RICE may be operated in non-emergency
    situations no more than 50 hours per year.

> *You only have to submit an initial notification for new or
> reconstructed emergency stationary RICE; existing emergency stationary
> RICE do not have to submit this form and are not subject to any
> requirements under subpart ZZZZ*

2.  **Limited Use Stationary RICE:** A limited use stationary RICE is
    any stationary RICE that operates less than 100 hours per year.

> *You only have to submit an initial notification for new or
> reconstructed emergency stationary RICE; existing emergency stationary
> RICE do not have to submit this form and are not subject to
> requirements under subpart ZZZZ.*

3.  **Stationary RICE that combust landfill gas or digester gas
    equivalent to 10 percent or more of the gross heat input on an
    annual basis.** Landfill gas is the gaseous by-product of the land
    application of municipal refuse typically formed through the
    anaerobic decomposition of waste materials and is composed primarily
    of methane and CO~2~. Digester gas is the gaseous by-product of
    wastewater treatment typically formed through the anaerobic
    decomposition of organic waste materials and is composed primarily
    of methane and CO~2~*.*

> *You have to submit an initial notification for new or reconstructed
> stationary RICE that meet these criteria. You also have monitoring,
> recordkeeping, and reporting requirements related to your annual fuel
> usage. Existing stationary RICE do not have to submit this form and
> are not subject to requirements under subpart ZZZZ*.

4.  **Spark ignition 4-stroke rich burn (4SRB) stationary RICE:** A
    stationary RICE is a spark ignition engine when the compressed
    air/fuel mixture of the engine is ignited by a timed electric spark
    generated by a spark plug. The engine is a spark ignition
    four-stroke stationary RICE if the power cycle is completed in two
    crankshaft revolutions, with intake and compression strokes in the
    first revolution and power and exhaust strokes in the second
    revolution. The engine is a rich burn stationary RICE if it is a
    4-stroke engine where the manufacturer's recommended operating
    air/fuel ratio divided by the stoichiometric air/fuel ratio at full
    load conditions is less than or equal to 1.1. If the engine was
    originally manufactured as a rich burn engine, but was modified
    before December 19, 2002 with passive emission control technology
    for nitrogen oxides (NO~x~) (such as pre-combustion chambers) it is
    considered a lean burn engine. Also, if existing engines (engines
    where construction was commenced before December 19, 2002) have no
    manufacturer's recommendations for air/fuel ratio, they are
    considered rich burn engines if the excess oxygen content of the
    exhaust at full load conditions is less than or equal to 2 percent.

> *You have to submit an initial notification for existing, new, or
> reconstructed stationary RICE that meet these criteria. You also have
> to meet all MACT requirements under subpart ZZZZ.*

5.  **Spark ignition 2-stroke lean burn (2SLB) stationary RICE:** An
    engine is a spark ignition engine when the compressed air/fuel
    mixture of the engine is ignited by a timed electric spark generated
    by a spark plug. A 2-stroke engine is an engine that completes the
    power cycle in a single crankshaft revolution. All spark ignition
    2-stroke engines are considered 2SLB under the subpart ZZZZ.

> *You have to submit an initial notification for new or reconstructed
> stationary RICE that meet these criteria. You also have to meet all
> MACT requirements under subpart ZZZZ. Existing stationary RICE do not
> have to submit this form and are not subject to requirements under
> subpart ZZZZ*.

6.  **4-stroke lean burn (4SLB) stationary RICE:** An engine is a spark
    ignition engine when the compressed air/fuel mixture of the engine
    is ignited by a timed electric spark generated by a spark plug. The
    engine is 4-stroke engine if it completes the power cycle in two
    crankshaft revolutions, with intake and compression strokes in the
    first revolution and power and exhaust strokes in the second
    revolution. The engine is a 4SLB stationary RICE if it is a 4-stroke
    engine and is not a rich burn engine.

> *You have to submit an initial notification for new or reconstructed
> stationary RICE that meet these criteria. You also have to meet all
> MACT requirements under subpart ZZZZ. Existing stationary RICE do not
> have to submit this form and are not subject to requirements under
> subpart ZZZZ*.

7.  **Compression ignition (CI) stationary RICE**: The engine is a CI
    engine if a high boiling point liquid fuel injected into the
    combustion chamber of the engine ignites when the air charge has
    been compressed to a temperature sufficiently high for
    auto-ignition. Compression engines include diesel engines, dual-fuel
    engines (engines where liquid fuel, usually diesel fuel, is used for
    compression ignition and a gaseous fuel, usually natural gas, is
    used as the primary fuel), and engines that are not spark ignition
    engines.

> *You have to submit an initial notification for new or reconstructed
> stationary RICE that meet these criteria. You also have to meet all
> MACT requirements under subpart ZZZZ. Existing stationary RICE do not
> have to submit this form and are not subject to requirements under
> subpart ZZZZ*.

**Question 4. Description of the Major Source, Identification of
Emission Points and HAP Emitted (40 CFR §63.9(b)(2)(iv))**

The intent of this question is to give the States an idea of the HAPs
emitted under subpart ZZZZ. Primary HAP emitted from this stationary
RICE are typically formaldehyde, acrolein, methanol, and acetaldehyde.

**Question 5. Signature**

This section must be signed by an authorized representative of the
member company that is responsible for the overall operation of the
facility. 40 CFR 70.2 defines a responsible official as the President,
Secretary, Treasurer, or Vice President of the company or the affected
sources designated representative under title V or part 70 activities.

[^1]: A "seasonal source" is a stationary source that stays in a single
    location for at least two years and operates for three months or
    more each year. An engine located at a seasonal source remains at a
    seasonal source during the full annual operating period. (For
    example, if the seasonal source operates for three months per year,
    the engine must remain at the seasonal source for at least three
    months.)

[^2]: "Associated equipment" is equipment associated with an oil or
    natural gas exploration or production well, and includes all
    equipment from the well bore to the point of custody transfer,
    except glycol dehydration units, storage vessels with potential for
    flash emissions, combustion turbines, and stationary RICE.

[^3]: "Oil and gas production facility" means any grouping of equipment
    where hydrocarbon liquids are processed, upgraded (i.e., remove
    impurities or other constituents to meet contract specifications),
    or stored prior to the point of custody transfer; or where natural
    gas is processed, upgraded, or stored prior to entering the natural
    gas transmission and storage source category. For purposes of a
    major source determination, "facility" (including a building,
    structure, or installation) means oil and natural gas production and
    processing equipment that is located within the boundaries of an
    individual surface site as defined in this section. Equipment that
    is part of a facility will typically be located within close
    proximity to other equipment located at the same facility. Pieces of
    production equipment or groupings of equipment located on different
    oil and gas leases, mineral fee tracts, lease tracts, subsurface or
    surface unit areas, surface fee tracts, surface lease tracts, or
    separate surface sites, whether or not connected by a road,
    waterway, power line or pipeline, shall not be considered part of
    the same facility. Examples of facilities in the oil and natural gas
    production source category include, but are not limited to, well
    sites, satellite tank batteries, central tank batteries, a
    compressor station that transports natural gas to a natural gas
    processing plant, and natural gas processing plants.

[^4]: "Production field facility" means those oil and gas production
    facilities located prior to the point of custody transfer.

[^5]: "Natural gas transmission and storage facility" means any grouping
    of equipment where natural gas is processed, compressed, or stored
    prior to entering a pipeline to a local distribution company or (if
    there is no local distribution company) to a final end user.
    Examples of a facility for this source category are: an underground
    natural gas storage operation; or a natural gas compressor station
    that receives natural gas via pipeline, from an underground natural
    gas storage operation, or from a natural gas processing plant. The
    emission points associated with these phases include, but are not
    limited to, process vents. Processes that may have vents include,
    but are not limited to, dehydration and compressor station engines.
    For the purpose of a major source determination, facility means
    natural gas transmission and storage equipment that is located
    inside the boundaries of an individual surface site and is connected
    by ancillary equipment, such as gas flow lines or power lines.
    Equipment that is part of a facility will typically be located
    within close proximity to other equipment located at the same
    facility. Natural gas transmission and storage equipment or
    groupings of equipment located on different gas leases, mineral fee
    tracts, lease tracts, subsurface unit areas, surface fee tracts, or
    surface lease tracts shall not be considered part of the same
    facility.

[^111]: "Associated equipment" is equipment associated with an oil or
    natural gas exploration or production well, and includes all
    equipment from the well bore to the point of custody transfer,
    except glycol dehydration units, storage vessels with potential for
    flash emissions, combustion turbines, and stationary RICE.

[^112]: "Oil and gas production facility" means any grouping of
    equipment where hydrocarbon liquids are processed, upgraded (i.e.,
    remove impurities or other constituents to meet contract
    specifications), or stored prior to the point of custody transfer;
    or where natural gas is processed, upgraded, or stored prior to
    entering the natural gas transmission and storage source category.
    For purposes of a major source determination, "facility" (including
    a building, structure, or installation) means oil and natural gas
    production and processing equipment that is located within the
    boundaries of an individual surface site as defined in this section.
    Equipment that is part of a facility will typically be located
    within close proximity to other equipment located at the same
    facility. Pieces of production equipment or groupings of equipment
    located on different oil and gas leases, mineral fee tracts, lease
    tracts, subsurface or surface unit areas, surface fee tracts,
    surface lease tracts, or separate surface sites, whether or not
    connected by a road, waterway, power line or pipeline, shall not be
    considered part of the same facility. Examples of facilities in the
    oil and natural gas production source category include, but are not
    limited to, well sites, satellite tank batteries, central tank
    batteries, a compressor station that transports natural gas to a
    natural gas processing plant, and natural gas processing plants.

[^113]: "Natural gas transmission and storage facility" means any
    grouping of equipment where natural gas is processed, compressed, or
    stored prior to entering a pipeline to a local distribution company
    or (if there is no local distribution company) to a final end user.
    Examples of a facility for this source category are: an underground
    natural gas storage operation; or a natural gas compressor station
    that receives natural gas via pipeline, from an underground natural
    gas storage operation, or from a natural gas processing plant. The
    emission points associated with these phases include, but are not
    limited to, process vents. Processes that may have vents include,
    but are not limited to, dehydration and compressor station engines.
    For the purpose of a major source determination, facility means
    natural gas transmission and storage equipment that is located
    inside the boundaries of an individual surface site and is connected
    by ancillary equipment, such as gas flow lines or power lines.
    Equipment that is part of a facility will typically be located
    within close proximity to other equipment located at the same
    facility. Natural gas transmission and storage equipment or
    groupings of equipment located on different gas leases, mineral fee
    tracts, lease tracts, subsurface unit areas, surface fee tracts, or
    surface lease tracts shall not be considered part of the same
    facility.
