Please mail this completed form to both your State Air Pollution Control
Office and your EPA Regional Office

**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[^1]) 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.[^2]

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.[^3]

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[^4] 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.[^5]

        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. [^6]

        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: [^7]

> $$\text{Throughput} = \frac{8,\text{760}}{\left( \frac{1}{\text{IR}_{\text{max}}}\  + \ \frac{1}{\text{WR}_{\text{max}}} \right)}$$
>
> 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.[^8]

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.

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.[^9] 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]: "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.

[^2]: "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.

[^3]: "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.
