C. Judicial Review

Under CAA section 307(b)(1), judicial review of this final rule is available only by filing a petition for review in the Court by May 20, 2011. Section 307(d)(7)(B) of the CAA further provides that ‘‘ only an objection to this final rule
that was raised with reasonable specificity during the period for public comment can be raised during judicial

review. ’’ This section also provides a
mechanism for EPA to convene a proceeding for reconsideration, ‘‘ [i]f the person raising an objection can
demonstrate to EPA that it was impracticable to raise such objection within [the period for public comment] or if the grounds for such objection arose after the period for public comment (but within the time specified for judicial review) and if such objection
is of central relevance to the outcome of
this rule. ’’ Any person seeking to make
such a demonstration to EPA should
submit a Petition for Reconsideration to the Office of the Administrator, Environmental Protection Agency, Room 3000, Ariel Rios Building, 1200 Pennsylvania Ave., NW., Washington, DC 20004, with a copy to both of the contacts listed in the preceding **FOR**

**FURTHER INFORMATION CONTACT** section,
and the Associate General Counsel for the Air and Radiation Law Office, Office of General Counsel (Mail Code 2344A), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20004. Note, under CAA section 307(b)(2), the requirements established by this final rule may not be challenged separately in any civil or criminal proceedings brought by EPA to enforce these requirements. II. Background

A. What is the statutory background for this final rule?

Section 129 of the CAA, entitled,

‘‘ Solid Waste Combustion, ’’ requires EPA to develop and adopt standards for solid waste incineration units pursuant
to CAA sections 111 and 129. Section 129(a)(1)(A) of the CAA requires EPA to establish performance standards, including emission limitations, for

‘‘ solid waste incineration units. ’’ Section
129 of the CAA defines ‘‘ solid waste

incineration unit’’ as ‘‘ a distinct operating unit of any facility which combusts any solid waste material from
commercial or industrial establishments or the general public ’’ (section 129(g)(1)). Section 129 of the CAA also provides that ‘‘ solid waste ’’ shall have the meaning established by EPA pursuant to its authority under the RCRA (section 129(g)(6)). Sections 111(b) and 129(a) of the CAA address emissions from new units ( i.e., NSPS), and CAA sections 111(d) and 129(b) address emissions from existing units ( i.e., EG). The NSPS are directly enforceable Federal regulations, and under CAA section 129(f)(1), become effective 6 months after promulgation. Unlike the NSPS, the EG are not themselves directly enforceable. Rather, the EG are implemented and enforced through either an EPA-approved state plan or a promulgated Federal plan.


### 15374 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

1 Sierra Club v. EPA; DC Cir. Nos. 06–1066, 07–

1063. States are required to submit a plan to implement and enforce the EG to EPA for approval not later than 1 year after EPA promulgates the EG (CAA section 129(b)(2)). The state plan must be ‘‘ at least as protective as ’’ the EG and must ensure compliance with all applicable requirements not later than 3 years after the state plan is approved by EPA, or 5 years after promulgation of the relevant EG, whichever is sooner. EPA’s procedures for submitting and approving state plans are set forth in 40 CFR part 60, subpart B. When a state plan is approved by EPA, the plan requirements become federally enforceable, but the state has primary responsibility for implementing and enforcing the plan. However, EPA is required to develop, implement, and enforce a Federal plan for solid waste incineration units located in any state which has not submitted an approvable state plan within 2o years after the date of promulgation of the relevant EG (CAA section 129(b)(3)). The Federal plan must assure that each solid waste incineration unit subject to the Federal plan is in compliance with all provisions of the EG not later than 5 years after the date the relevant guidelines are promulgated. EPA views the Federal plan as a ‘‘ place-holder’’ that remains in effect only until such time as a state without an approved plan submits and receives EPA approval of its state plan. Once an applicable state plan has been approved, the requirements of the Federal plan no longer apply to solid waste incineration units covered by that state plan.

The CAA sets forth a two-stage approach to regulating emissions from
solid waste incinerator units. The statute also provides EPA with substantial discretion to distinguish among classes, types, and sizes of incineration units within a category while setting standards. In the first stage of setting standards, CAA section 129(a)(2) requires EPA to establish technology-based emission standards
that reflect levels of control EPA
determines are achievable for new and existing units, after considering costs, nonair quality health and environmental impacts and energy requirements associated with the implementation of the standards. Section 129(a)(5) of the
CAA then directs EPA to review those standards and revise them as necessary every 5 years. In the second stage, CAA section 129(h)(3) requires EPA to
determine whether further revisions of the standards are necessary in order to provide an ample margin of safety to protect public health.

In setting forth the methodology EPA must use to establish the first-stage technology-based standards for the standards, CAA section 129(a)(2) provides that standards ‘‘ applicable to
solid waste incineration units promulgated under section 111 and this
section shall reflect the maximum degree of reduction in emissions of [certain listed air pollutants] that the Administrator, taking into consideration the cost of achieving such emission reduction and any nonair quality health and environmental impacts and energy requirements, determines is achievable for new and existing units in each
category. ’’ This level of control is
referred to as a MACT standard.

In promulgating a MACT standard,
EPA must first calculate the minimum stringency levels for new and existing
solid waste incineration units in a category, generally based on levels of emissions control achieved or required to be achieved by the subject units. The minimum level of stringency is called
the MACT ‘‘ floor, ’’ and CAA section 129(a)(2) sets forth differing levels of minimum stringency that EPA’s standards must achieve, based on whether they regulate new and reconstructed sources, or existing
sources. For new and reconstructed sources, CAA section 129(a)(2) provides
that the ‘‘ degree of reduction in
emissions that is deemed achievable * * * shall not be less stringent than
the emissions control that is achieved in practice by the best controlled similar unit, as determined by the
Administrator. ’’ Emissions standards for existing units may be less stringent than standards for new units, but ‘‘ shall not be less stringent than the average emissions limitation achieved by the best performing 12 percent of units in the category. ’’

Maximum Achievable Control Technology analyses involve an
assessment of the emissions from the best performing unit or units in a source category. The assessment can be based on actual emissions data, knowledge of the air pollution control in place in combination with actual emissions data, state regulatory requirements that may
enable EPA to estimate the actual performance of the regulated units, or
other emissions information. For each source category, the assessment involves
a review of actual emissions data with an appropriate accounting for emissions variability. Other methods of estimating emissions can also be used, if the methods can be shown to provide
reasonable estimates of the actual emissions performance of a source or
sources. In addition to the MACT floor limit, EPA must examine whether more stringent ‘‘beyond-the-floor’’ standards should be adopted. In considering whether such standards are appropriate, EPA must consider the cost of achievingsuch emission reduction, and any nonair quality health and environmental impacts and energy requirements. The CAA requires that the MACT floor for new sources be no less stringent than
the emissions control achieved in practice by the best-controlled similar unit. EPA is also required to consider beyond-the-floor standards for new sources, consistent with the factors
described above. Clean Air Act section 129(a)(1) identifies five categories of
solid waste incineration units:

• Units that combust municipal waste at a capacity greater than 250 tpd.

• Units that combust municipal waste at a capacity equal to or less than 250 tpd.

• Units that combust hospital, medical, and infectious waste.

• Units that combust commercial or
industrial waste.

• Units that combust waste and which are not specifically identified in section 129(a)(1)(A) through (D) are referred to in section 129(a)(1)(E) as

‘‘ other categories ’’ of solid waste

incineration units.

A SSI unit is an incinerator located at a wastewater treatment facility designed to treat domestic sewage sludge that combusts sewage sludge for the purpose of reducing the volume of the sewage sludge by removing combustible matter. Sewage sludge incinerators, by virtue of having not been specifically identified in section 129(a)(1)(A) through (D), have been interpreted to be part of the broader category of ‘‘ other categories ’’ of
solid waste. EPA has issued emission standards for large and small MWC, HMIWI, CISWI, and OSWI units; however, as explained further below, none of those emission standards apply

to SSI units.

EPA issued emission standards for OSWI units on December 16, 2005 (70 FR 74870). Based on EPA’s interpretation of the CAA at that time,
the OSWI standards did not include
emission standards for SSI units. EPA received a petition for reconsideration of the OSWI standards on February 14, 2006, regarding the exclusion of certain categories, including SSI. 1 While EPA granted the petition for reconsideration on June 28, 2006, EPA’s final review, which became effective January 22, 2007, concluded that no additional changes were necessary to the 2005 OSWI rule (71 FR 36726). That litigation is currently being held in abeyance. EPA currently intends to revise the emission standards for OSWI units in the future,

2 NRDC v. EPA; 489 F. 3d. at 1257–8.

3 CAA section 112(c)(3) and section 112(k)(3)(B)(ii). 4 Sierra Club v. Jackson; D.DC No. 1:01CV01537. and that rulemaking will address all OSWI units except SSI units.

In the OSWI rule issued on December 16, 2005, EPA stated that it had decided not to regulate SSI units under CAA section 129 (70 FR 74870), but rather to regulate SSI units under CAA section 112, pointing to a statement in EPA’s 2000 Unified Regulatory Agenda stating that sewage sludge incinerators do not
combust waste from a commercial or industrial establishment or the general public. We declined to revise that decision to regulate SSI units under 112 in the response to the petition for
reconsideration on this issue for five reasons, including our position that section 129(a)(1)(E) did not require regulation of all ‘‘ other’’ solid waste
incineration units and that section 129(g)(1)’s enumerated exemptions to
the definition of ‘‘ solid waste

incineration unit’’ were not exclusive, and that section 129(h)(2) gave EPA the discretion to choose whether to regulate
incinerators under section 112 or section 129 of the Act. (72 FR 2620). In June 2007, in a separate decision related to EPA’s December 1, 2000, emission standards for CISWI units, the Court held that any unit combusting any solid waste must be regulated under section 129 of the CAA. The impact of this decision on EPA’s regulation of SSI is explained in detail in the NPRM. 2

EPA considers SSI units to be ‘‘ other solid waste incineration units, ’’ since that category is intended to encompass
all solid waste incineration units that
are not included in the first four categories identified in CAA section 129(a) through (d). EPA plans to re-issue emission standards for the remaining OSWI units at a later time. EPA is taking
final action on emission standards for
SSI units at this time because these emission standards are needed as part of EPA’s fulfillment of its obligations under CAA sections 112(c)(3) and (k)(3)(B)(ii) and section 112(c)(6). Clean Air Act section 112(k)(3)(B)(ii) calls for EPA to identify at least 30 HAP which,
as the result of emissions from area sources, pose the greatest threat to public health in the largest number of
urban areas. EPA must then ensure that sources representing 90 percent of the aggregate area source emissions of each of the 30 identified HAP are subject to standards pursuant to section 112(d). 3 Sewage sludge incineration units are one of the source categories identified for regulation to meet the 90 percent requirement for Cd, Cr, Pb, Mn, Hg, Ni and PCB. EPA is ordered by the Court to satisfy its obligation under CAA section 112(c)(3) and (k)(3)(B)(ii) by January 16, 2011. 4

In a notice on April 10, 1998, EPA provided a list of source categories for regulation under CAA section 112(d)(2) or 112(d)(4). Section 112(c)(6) of the CAA requires EPA to identify categories of sources of seven specified pollutants to assure that sources counting for not less than 90 percent of the aggregate emissions of each such pollutant are subject to standards under CAA section 112(d)(2) or 112(d)(4) (63 FR 17838). Sewage sludge incineration units are one of the identified source categories for regulation to meet the 90 percent requirement for Hg. Further information can be found in the Memorandum titled,

‘‘Emission Standards for Meeting the Ninety Percent Requirement under Section 112(c)(6) of the Clean Air Act’’ in the SSI docket (EPA–HQ–OAR–2009– 0559).Therefore, EPA is finalizing the SSI standards prior to taking action on the remaining source categories that will be regulated under CAA section 129(a)(1)(E) as OSWI units.

B. What are the primary sources of
emissions and what are the emissions?

Sewage sludge incineration units may be operated by municipalities or other
entities. Incineration continues to be used to dispose of sewage sludge. Combustion of solid waste, and specifically sewage sludge, causes the release of a wide array of air pollutants,
some of which exist in the waste feed material and are released unchanged during combustion, and some of which are generated as a result of the combustion process itself. The pollutants for which numerical limits must be established, as specified in section 129 of the CAA, include Cd, CO, HCl, Hg, NO X , PCDD/PCDF, PM, Pb, and

SO 2 ; and, where appropriate, numerical limits for opacity must also be
established. These emissions come from the SSI unit’s stack and fugitive PM emissions, as indicated by the associated visible emissions, also occur from ash handling.

C. What is the relationship of the final standards to other standards for the use or disposal of sewage sludge and
associated air emissions?

Under authority of section 405(d) and (e) of the CWA, as amended 33 U.S.C.A. 1251, ( et seq. ), EPA promulgated regulations on February 19, 1993, at 40 CFR part 503 designed to protect public health and the environment from any reasonably anticipated adverse effects of certain pollutants that may be present in sewage sludge. The part 503 regulations establish requirements for the final use and disposal of sewage sludge when: (1) The sludge is applied to the land for a beneficial use ( e.g., for use in home gardens); (2) the sludge is disposed on land by placing it on surface disposal sites; and (3) the sewage sludge is incinerated. The standards apply to POTW that generate or treat domestic sewage sludge, as well as to any person who uses or disposes of sewage sludge
from such treatment works.

The part 503 requirements for firing sewage sludge in a SSI are in subpart E of the regulations. Subpart E includes general requirements; pollutant limits; operational standards; management practices; and monitoring, recordkeeping, and reporting requirements.

These part 503 regulations require
that SSI meet the National Emission Standards for Beryllium and Hg in subparts C and E, respectively, of 40 CFR part 61. The regulations also require that the allowable concentration of five other inorganic pollutants be calculated using equations in the regulation. The inorganic pollutants included are Pb, As, Cd, Cr, and Ni. The terms in the equations must be determined on a case-by-case basis, except for the risk-specific
concentration for the inhalation exposure pathway to protect individuals when these pollutants are inhaled. The site-specific variables for the equations (incinerator type, dispersion factor, control efficiency, feed rate, and stack height) must be used to calculate allowable daily concentrations of As, Cd, Cr, Pb and Ni in the sewage sludge
fed to the incinerator.

Also included in subpart E of part 503 is an operational standard for THC. The value for THC in the final part 503 regulation cannot be exceeded in the exit gas from the SSI stack. Management practices and frequency of monitoring, recordkeeping, and reporting requirements are also included in this subpart.

Under today’s final standards, EPA is establishing limits for three of the inorganic pollutants covered by the current part 503 regulations (Cd, Pb and Hg) and the following six additional pollutants: HCl, CO, NO X , SO 2 , PM, and
total PCDD/PCDF. Besides the pollutants covered here, there are other differences between the part 503 regulations and these final standards. The emission limits for inorganic pollutants under part 503 are risk-based numbers rather than technology-based. Also, part 503 does not distinguish between new and existing units or between incinerator types ( i.e., MH or


### 15376 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

FB incinerator) for setting emission
limits since emission limits are based on risks to a highly exposed individual.

Because both part 503 and these final
standards cover the same universe of facilities, there are certain issues that arise in terms of potential impacts to current SSI facilities. First, the regulation of sewage sludge under CAA
section 129 will result in stricter
emission standards than under the current CWA rule. Additional pollution
controls will increase costs for facilities
that continue to use the incineration disposal method. If the additional costs are high enough, many entities may choose to adopt alternative disposal methods ( e.g., surface disposal in
landfills or other beneficial land applications). Consequently, a potential impact of this rule is that some of the estimated 110 facilities that operate SSI as the primary means of disposal could discontinue this practice and would instead landfill or land apply their sewage sludge. Second, one must consider the available capacity of surface disposal sites to receive additional sewage sludge and the potential for added costs if the use of SSI is discontinued. Third, SSI will be subject to two different sets of requirements (numeric standards, operational standards, monitoring, recordkeeping, and reporting) under the two different statutes, creating an
additional burden to these facilities unless alternative regulatory approaches are implemented. EPA plans to evaluate the requirements under both statutes to determine what changes, if any, should be made to the part 503 regulations.

III. Summary of the Final Standards

This preamble discusses the final standards as they apply to the owner or operator of a new or existing SSI unit. This preamble also describes the major requirements of the SSI regulations. For a full description of the final requirements and compliance times, see the SSI standards in subparts LLLL and

MMMM.

A. What units are affected by the final
standards?

The final standards and guidelines apply to owners or operators of SSI units (as defined in 40 CFR 60.4780 and 40 CFR 60.5065) located at wastewater treatment facilities designed to treat domestic sewage sludge. A SSI unit is an enclosed device or devices using
controlled flame combustion that burns sewage sludge for the purpose of reducing the volume of the sewage sludge by removing combustible matter. A SSI unit also includes, but is not limited to, the sewage sludge feed system, auxiliary fuel feed system, grate system, flue gas system, waste heat recovery equipment, if any, and bottom ash system. The SSI unit includes all ash handling systems connected to the bottom ash handling system. The combustion unit bottom ash system ends at the truck loading station or similar equipment that transfers the ash to final disposal. The SSI unit does not include air pollution control equipment or the stack. The affected facility is each
individual SSI unit. The SSI standards in subparts LLLL and MMMM apply to new and existing SSI units that burn sewage sludge as defined in the subparts. The final standards define two subcategories for new and existing SSI
units: MH incinerators and FB

incinerators.

The combustion of sewage sludge that
is not burned in a SSI unit located at a wastewater treatment facility designed to treat domestic sewage sludge is subject to other section 129 standards, such as the CISWI standards (40 CFR part 60, subparts CCCC and DDDD of this part), the OSWI standards (40 CFR part 60, subparts EEEE and FFFF), the MWC standards (40 CFR part 60, subparts Ea, Eb, Cb, AAAA, and BBBB of this part) or the Hazardous Waste Combustor rule (40 CFR part 63 subpart EEE).

B. What are the emission limits in the emission guidelines for existing sources?

The final emission limits for existing
sources in the MH incinerator subcategory and FB incinerator subcategory are presented in Table 1 of this preamble. Existing sources may comply with either the PCDD/PCDF TEQ or TMB emission limits.

These standards apply at all times.

D. What are the testing and monitoring requirements?

These final standards require all new and existing SSI units to demonstrate initial and annual compliance with the emission limits using EPA-approved
emission test methods. The final standards also provide an option for less frequent testing if sources demonstrate that their emissions of regulated pollutants are below thresholds of the
emission limits.

For existing SSI units, the EG requires
initial and annual emissions performance tests (or continuous emissions monitoring or continuous sampling as an alternative), bag leak detection systems for FF controlled units, continuous parameter monitoring, and annual inspections of air pollution control devices, if they are used to meet the emission limits. Additionally, existing units are required to conduct Method 22 ( see 40 CFR part 60, appendix A–7) visible emissions test of the ash handling operations during each compliance test.

For new SSI units, the NSPS requires
initial and annual emissions performance tests (or continuous emissions monitoring or continuous sampling as an alternative), bag leak detection systems for FF controlled units, as well as continuous parameter monitoring and annual inspections of air pollution control devices that may be
used to meet the emission limits. The final rule requires all new SSI units to install a CO CEMS. Operators of new units are also required to conduct Method 22 visible emissions testing of the ash handling operations during each compliance test.

For existing SSI units, use of Cd, CO, HCl, NO X , PM, Pb or SO 2 CEMS; ISTMMS; and ISTDMS (continuous sampling with periodic sample analysis) are approved alternatives to parametric monitoring and annual compliance testing. For new SSI units, CO CEMS are required, and use of Cd, HCl, NO X , PM,
Pb or SO 2 CEMS; ISTMMS; and ISTDMS (continuous sampling, with periodic sample analysis) are approved alternatives to parametric monitoring and annual compliance testing.

E. What are the other requirements for new and existing SSI units?

Owners or operators of new or existing SSI units are required to meet operator training and qualification requirements, which include: Ensuring that at least one operator or supervisor per facility complete the operator training course, that qualified operator(s) or supervisor(s) complete an
annual review or refresher course specified in the regulation, and that they maintain plant-specific information, updated annually, regarding training.

Owners or operators of new SSI units are required to conduct a siting analysis, which includes submitting a report that evaluates site-specific air pollution
control alternatives that minimize potential risks to public health or the environment, considering costs, energy impacts, non-air environmental impacts and any other factors related to the practicability of the alternatives.

Owners or operators of new or existing SSI units are required to submit a monitoring plan for any continuous monitoring system or bag leak detection system used to comply with the rule. They must also submit a monitoring plan for their ash handling system that specifies the operating procedures they will follow to ensure that they meet the fugitive emission limit.

F. What are the recordkeeping and reporting requirements?

Records of the initial and all subsequent stack or PS tests, deviation reports, operating parameter data, continuous monitoring data, maintenance and inspections of the air pollution control devices, the siting analysis (for new units only), monitoring plan and operator training and qualification must be maintained for 5 years. The results of the stack tests and PS tests and values for operating parameters are required to be included in initial and subsequent compliance
reports. G. What are the SSM provisions?
The Court vacated portions of two provisions in EPA’s CAA section 112 regulations governing the emissions of HAP during periods of SSM. Sierra Club

v. EPA, 551 F.3d 1019 (D.C. Cir. 2008), cert. denied, 130 S. Ct. 1735 (U.S. 2010). Specifically, the Court vacated the SSM exemption contained in 40 CFR 63.6(f)(1) and 40 CFR 63.6(h)(1), (the

‘‘ General Provisions Rule, ’’ ) that EPA promulgated under section 112 of the CAA. When incorporated into CAA section 112(d) regulations for specific source categories, these two provisions exempt sources from the requirement to comply with the otherwise applicable CAA section 112(d) emission standard during periods of SSM.

While the Court’s ruling in Sierra
Club v. EPA directly affects only the subset of CAA section 112(d) rules that incorporate 40 CFR 63.6(f)(1) and (h)(1) by reference and that contain no other regulatory text exempting or excusing compliance during SSM events, the legality of source category-specific SSM provisions is questionable.

Consistent with Sierra Club v. EPA, EPA is requiring that emission
limitations in these final standards apply at all times the unit is operating. In establishing these standards, EPA has taken into account startup and shutdown periods and, for the reasons explained below, has not established different standards for those periods.

We are not promulgating a separate
emission standard for the source category that applies during periods of startup and shutdown. Based on the information available at this time, we
believe that SSI units will be able to meet the emission limits during periods of startup. Units we have information on use natural gas, landfill gas, or distillate
oil to start the unit and add waste once
the unit has reached combustion temperatures. Emissions from burning natural gas, landfill gas or distillate fuel oil are expected to generally be lower than from burning solid wastes. Emissions during periods of shutdown are also generally lower than emissions during normal operations because the


### 15378 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

5 See, Weyerhaeuser v. Costle, 590 F.2d 1011, 1058 (DC Cir. 1978) ( ‘‘In the nature of things, no general limit, individual permit, or even any upset provision can anticipate all upset situations. After a certain point, the transgression of regulatory limits caused by ‘uncontrollable acts of third parties,’ such as strikes, sabotage, operator intoxication or insanity, and a variety of other eventualities, must be a matter for the administrative exercise of case-by-case enforcement discretion, not for specification in advance by regulation. ’’ ). 6 40 CFR 60.2 (definition of malfunction).

7 See, e.g., State Implementation Plans: Policy Regarding Excessive Emissions During Malfunctions, Startup, and Shutdown (Sept. 20, 1999); Policy on Excess Emissions During Startup, Shutdown, Maintenance, and Malfunctions (Feb. 15, 1983).

8 See proposed definition 40 CFR 60.4930 and 40 CFR 60.5250 (defining ‘‘ affirmative defense ’’ to mean, in the context of an enforcement proceeding, a response or defense put forward by a defendant, regarding which the defendant has the burden of proof, and the merits of which are independently and objectively evaluated in a judicial or administrative proceeding). 9 40 CFR 70.6(a)(1), 70.2, 71.6(a)(1) and 71.2. materials in the incinerator would be almost fully combusted before shutdown occurs. Furthermore, the approach for establishing MACT floors
for SSI units ranked individual SSI units based on actual performance for each pollutant and subcategory, with an appropriate accounting of emissions variability. Because we accounted for emissions variability, we believe we have adequately addressed any minor variability that may potentially occur during startup or shutdown.

Periods of startup, normal operations, and shutdown are predictable and routine aspects of a source’s operations. However, by contrast, malfunction is
defined as a ‘‘ 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 * * * ’’ (40 CFR 60.2). EPA has
determined that malfunctions should not be viewed as a distinct operating mode and, therefore, any emissions that
occur at such times do not need to be factored into development of CAA section 129 standards, which, once promulgated, apply at all times. Nothing
in CAA section 129 or in case law requires that EPA anticipate and account for the innumerable types of potential malfunction events in setting
emission standards. 5

Further, it is reasonable to interpret CAA section 129 as not requiring EPA to account for malfunctions in setting emissions standards. For example, we
note that CAA section 129 uses the concept of ‘‘best controlled’’ or ‘‘best performing ’’ sources in defining MACT, the level of stringency that major source standards must meet. Applying the concept of ‘‘best controlled’’ or ‘‘best performing ’’ to a source that is malfunctioning presents significant difficulties. The goal of best controlled or best performing sources is to operate in such a way as to avoid malfunctions
of their units.

Moreover, even if malfunctions were considered a distinct operating mode, we believe it would be impracticable to
take malfunctions into account in setting CAA section 129 standards for SSI. As noted above, by definition,
malfunctions are sudden and unexpected events, and it would be
difficult to set a standard that takes into account the myriad different types of
malfunctions that can occur across all sources in the category. Moreover, malfunctions can vary in frequency, degree, and duration, further complicating standard setting.

For the SSI standards, malfunctions are required to be reported in deviation reports. We will then review the deviation reports to determine if the
deviation is a violation of the standards.

In the event that a source fails to comply with the applicable CAA section
129 standards as a result of a malfunction event, EPA would determine an appropriate response based on, among other things, the good
faith efforts of the source to minimize emissions during malfunction periods, including preventative and corrective actions, as well as root cause analyses to ascertain and rectify excess
emissions. EPA would also consider whether the source’s failure to comply with the CAA section 129 standard was, in fact, ‘‘ sudden, infrequent, not reasonably preventable ’’ and was not
instead ‘‘ caused in part by poor maintenance or careless operation. ’’ 6

Finally, EPA recognizes that even equipment that is properly designed and
maintained can fail and that such failure
can sometimes cause an exceedance of
the relevant emission standard. 7 EPA is therefore finalizing the proposed affirmative defense to civil penalties for
exceedances of emissions limits that are caused by malfunctions, with some revisions to the proposed regulatory provision. 8 Under this provision, the source must prove by a preponderance
of the evidence that it has met all of the
elements set forth in 40 CFR 60.4860
and in 40 CFR 60.5180. The criteria
ensure that the affirmative defense is available only where the event that
causes an exceedance of the emission
limit meets the narrow definition of malfunction in 40 CFR 60.2 (sudden, infrequent, not reasonable preventable and not caused by poor maintenance and or careless operation). For example, to successfully assert the affirmative defense, the source must prove by a preponderance of the evidence that

excess emissions ‘‘ [w]ere caused by a sudden, infrequent, and unavoidable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a
normal or usual manner * * *. ’’ The criteria also are designed to ensure that steps are taken to correct the malfunction, to minimize emissions in accordance with 40 CFR part 60, subpart LLLL and 40 CFR part 60, subpart MMMM and to prevent future malfunctions. For example, the source must prove by a preponderance of the
evidence that ‘‘ [r]epairs were made as expeditiously as possible when the applicable emission limitations were being exceeded * * * ’’ and that ‘‘ [a]ll possible steps were taken to minimize the impact of the excess emissions on ambient air quality, the environment
and human health * * *. ’’ In any judicial or administrative proceeding, the Administrator may challenge the assertion of the affirmative defense and, if the respondent has not met its burden of proving all of the requirements in the affirmative defense, appropriate penalties may be assessed in accordance with section 113 of the CAA ( see also 40 CFR 22.77).

H. What are the Title V permit requirements?

All new and existing SSI units regulated by the final SSI rule are required to apply for and obtain a Title V permit. These Title V operating permits assure compliance with all applicable requirements for regulated SSI units, including all applicable CAA section 129 requirements. 9

The permit application deadline for a CAA section 129 source applying for a Title V operating permit depends on when the source first becomes subject to the relevant Title V permits program. If a regulated SSI unit is a new unit and is not subject to an earlier permit application deadline, a complete Title V permit application must be submitted
on or before the relevant date below.

• For a SSI unit that commenced operation as a new source on or before the promulgation date of 40 CFR part 60, subpart LLLL, the source must submit a complete Title V permit application no later than 12 months after the promulgation date of 40 CFR part 60, subpart LLLL; or

• For a SSI unit that commences operation as a new source after the promulgation of 40 CFR part 60, subpart LLLL, the source must submit a complete Title V permit application no


### 15379 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

10 CAA section 503(c) and 40 CFR 70.5(a)(1)(i) and 71.5(a)(1)(i).

11 CAA section 503(c) and 40 CFR 70.3(a) and (b), 70.5(a)(1)(i), 71.3(a) and (b) and 71.5(a)(1)(i). later than 12 months after the date the SSI unit commences operation as a new

source. 10

If the SSI unit is an existing unit and is not subject to an earlier permit application deadline, then the source must submit a complete Title V permit application by the earlier of the following dates:

• Twelve months after the effective date of any applicable EPA-approved CAA section 111(d)/129 plan ( i.e., an EPA approved state or tribal plan that implements the SSI EG); or

• Twelve months after the effective date of any applicable Federal plan; or

• Thirty-six months after promulgation of 40 CFR part 60, subpart

MMMM.

For any existing SSI unit not subject to an earlier permit application deadline, the application deadline of 36 months after the promulgation of 40 CFR part 60, subpart MMMM, applies regardless of whether or when any applicable Federal plan is effective, or whether or when any applicable state or tribal CAA section 111(d)/129 plan is approved by EPA and becomes effective. ( See CAA sections 129(e), 503(c), 503(d), and 502(a) and 40 CFR 70.5(a)(1)(i) and 71.5(a)(1)(i).)

If the SSI unit is subject to Title V as a result of some triggering requirement(s) other than those mentioned above, for example, a SSI unit may be a major source (or part of a major source), then you may be required to apply for a Title V permit prior to the deadlines specified above. If more than one requirement triggers a source’s obligation to apply for a Title V permit, the 12-month time frame for filing a Title V permit application is triggered by the requirement which first causes the source to be subject to Title

V. 11

For additional background
information on the interface between CAA section 129 and Title V, including EPA’s interpretation of section 129(e), information on updating existing Title V permit applications and reopening existing Title V permits, see the final

‘‘ Federal Plan for Commercial and Industrial Solid Waste Incineration, ’’ October 3, 2003 (68 FR 57518), as well
as the ‘‘ Summary of Public Comments and Responses ’’ document in the OSWI docket (EPA–HQ–OAR–2003–0156).

I. What are the applicability dates of the
standards?

New SSI units that commence construction after October 14, 2010, or that are modified 6 months or more after the date of promulgation, must meet the NSPS emission limits of 40 CFR part 60, subpart LLLL within 6 months after the promulgation date of the standards or upon startup, whichever is later.

Under the final EG, and consistent with CAA section 129 (b)(2) and 40 CFR 60, subpart B, states are required to submit state plans containing the existing source emission limits of subpart MMMM of this part, and other requirements to implement and enforce the EG within 1 year after promulgation of the EG. States must submit state plans to EPA by March 21, 2012. State plans apply to existing SSI in the state (including SSI that are modified prior to and including the date 6 months after promulgation) and must be at least as protective as the EG.

The final EG requires existing SSI to demonstrate compliance with the standards as expeditiously as practicable after approval of a state plan, but no later than 3 years from the date of approval of a state plan or 5 years after promulgation of the EG, whichever
is earlier. Consistent with CAA section 129, EPA expects states to require compliance as expeditiously as practicable. However, because we believe that many SSI units will find it necessary to retrofit existing emissions control equipment and/or install additional emissions control equipment in order to meet the final limits, EPA anticipates that states may choose to provide the 3-year compliance period allowed by CAA section 129(f)(2). If EPA does not approve a state plan or issue a Federal plan, then the compliance date is 5 years from the date
of the final rule.

EPA intends to develop a Federal plan that will apply to existing SSI units in any state that has not submitted an approved state plan within 2 years after promulgation of the EG. The final EG allows existing SSI units subject to the Federal plan up to 5 years after promulgation of the EG to demonstrate compliance with the standards, as allowed by CAA section 129(b)(3).

J. What are the requirements for submission of emissions test results to

EPA?

EPA must have performance test data
to conduct effective reviews of CAA sections 112 and 129 standards, as well as for many other purposes including compliance determinations, emission factor development, and annual
emission rate determinations. In conducting these required reviews, EPA
has found it ineffective and time consuming, not only for us, but also for regulatory agencies and source owners and operators to locate, collect, and
submit emissions test data because of varied locations for data storage and varied data storage methods. One improvement that has occurred in recent years is the availability of stack test reports in electronic format as a replacement for cumbersome paper copies.

In this final rule, EPA is taking a step to improve data accessibility and increase the ease and efficiency of reporting for sources. Owners and operators of SSI facilities are required to submit, to EPA’s ERT database, electronic copies of reports of certain performance tests required under the SSI EG and NSPS. Data entry will be through an electronic emissions test report structure called the Emissions Reporting Tool (ERT) whenever conducting performance tests. The ERT was developed with input from stack testing companies who generally collect and compile performance test data electronically and offices within state and local agencies that perform field test assessments. The ERT is currently
available at http://www.epa.gov/ttn/ chief/ert/ert

_ tool.html, and access to
direct data submittal to EPA’s electronic emissions database (WebFIRE) will become available by December 31, 2011.

The requirement to submit source test data electronically to EPA would not require any additional performance testing and would apply to those performance tests conducted using test methods that are supported by the ERT. The ERT contains a specific electronic data entry form for most of the commonly used EPA reference methods.
The Web site listed below contains a listing of the pollutants and test methods supported by the ERT. In addition, when a facility submits performance test data to WebFIRE, there will be no additional requirements for emissions test data compilation. Moreover, we believe industry will benefit from development of improved emission factors, fewer follow-up information requests, and better regulation development as discussed below. The information to be reported is already required for the existing test methods and is necessary to evaluate
the conformance to the test method.

One major advantage of submitting source test data through the ERT is a standardized method to compile and
store much of the documentation required to be reported by this rule that also clearly states what testing information would be required. Another important benefit of submitting these
data to EPA at the time the source test
is conducted is that it should substantially reduce the effort involved


### 15380 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

in data collection activities in the future. When EPA has source category performance test data in hand, there will likely be fewer or less substantial data collection requests in conjunction with prospective required residual risk assessments or technology reviews. This
results in a reduced burden on both affected facilities (in terms of reduced manpower to respond to data collection requests) and EPA (in terms of preparing and distributing data collection requests and assessing the results).

State/local/tribal agencies may also benefit in that their review may be more streamlined and accurate because they
would not have to re-enter the data to assess the calculations and verify the data entry. Finally, another benefit of submitting these data to WebFIRE electronically is that these data will greatly improve the overall quality of the existing and new emission factors by supplementing the pool of emissions test data upon which the emission factor is based and by ensuring that data are more representative of current industry operational procedures. A common complaint heard from industry and regulators is that emissions factors are outdated or not representative of a particular source category. Receiving and incorporating data for most performance tests will ensure that emissions factors, when updated, represent accurately the most current range of operational practices. In summary, in addition to supporting regulation development, control strategy development, and other air pollution control activities, receiving test data already collected and using them in the emissions factors development program will save industry, state/local/tribal agencies, and EPA significant time, money, and effort while improving the quality of emission inventories and related regulatory decisions.

As mentioned earlier, the electronic
database that will be used is EPA’s WebFIRE, which is a Web site accessible through EPA’s TTN Web. The WebFIRE
Web site was constructed to store emissions test data for use in developing emission factors. A description of the
WebFIRE database can be found at http://cfpub.epa.gov/oarweb/index.cfm? action=fire.main. The ERT will be able to transmit the electronic report through EPA’s CDX network for storage in the WebFIRE database. Although ERT is not the only electronic interface that can be
used to submit source test data to the CDX for entry into WebFIRE, it makes submittal of data very straightforward and easy. A description of the ERT can
be found at http://www.epa.gov/ttn/chief/ert/ert

_ tool.html.

IV. Summary of Significant Changes Following Proposal

EPA received over 90 public comments on the proposed rulemaking. Furthermore, we conducted one public hearing to allow the public to comment on the proposed rulemaking. After consideration of public comments received, EPA is making several changes to the standards. Following are the major changes to the standards since the proposal. The rationale for these and any other significant changes can be found in section V of this preamble or
in the ‘‘ Sewage Sludge Incineration (SSI) Rule: Summary of Public Comments and Responses ’’ in the SSI docket (EPA–HQ– OAR–2009–0559).

A. Applicability

The final rule clarifies that, if any amount of sewage sludge is burned in

an incinerator at a wastewater treatment facility designed to treat domestic sewage sludge, the incinerator is subject to the SSI standards in subparts LLLL and MMMM of this part while burning sewage sludge. The final rule also clarifies that sewage sludge that is not
burned in a SSI located at a wastewater treatment facility designed to treat domestic sewage sludge is subject to other section 129 standards, such as the CISWI standards (40 CFR part 60, subparts CCCC and DDDD of this part), the OSWI standards (40 CFR part 60, subparts EEEE and FFFF), the MWC standards (40 CFR part 60, subparts Ea, Eb, Cb, AAAA, and BBBB of this part)
or the Hazardous Waste Combustor rule (40 CFR part 63 subpart EEE).

B. Subcategories

The proposed NSPS did not subcategorize new sources. In the final
NSPS, SSI units at new sources are subcategorized into two subcategories:
MH and FB.

C. MACT Floor UPL Calculation and EG
and NSPS Emission Limits

At proposal, we used a 99 percent
UPL calculation to determine variability. For the final rule, for existing FB units, we are using a weighted 99 percent UPL calculation to account for the biasing of emissions data from one facility. The weighted UPL
was not used for MH units. In the proposed rule, two statistical measures, skewness and kurtosis, were

examined to determine if the data used

to calculate the MACT floor were normally or log-normally distributed. If both the reported values and the natural-log transformed reported values

had skewness and kurtosis statistics that indicated neither were normally distributed, the reported dataset was

selected as the basis of the floor to be

conservative. If the results of the skewness and kurtosis hypothesis tests were mixed for the reported values and the natural log-transformed reported values, the analysis done on the reported data values was chosen to be

conservative. We have modified our assumptions when results of the

skewness and kurtosis tests do notclearly show whether a normal or lognormal distribution better represents the data, or when there are not enough data to complete the skewness and kurtosis tests. In these cases, we have chosen to use the log-normal results for the final

MACT floor calculation.

In the proposed rule, we proposed setting beyond-the-floor emission standards for Hg emissions from existing MH units. In the final rule, we are establishing MACT floor emissionlimits but are not setting beyond-thefloor standards. Also, we are not finalizing the proposed opacity limits. At proposal, we set emission limits for

both PCDD/PCDF TMB and PCDD/PCDF TEQ and required SSI units to meet both limits. In the final standards, we are allowing affected sources to comply

with either the PCDD/PCDF TMB or TEQ emission limits.

In the proposed rule, we did not compare the CO span of the test to the

measured CO values to determine if the

values were consistent. For the final rule, we reviewed the CO values obtained from emission test reports to determine whether the span of the test used was capable of accurately reading the reported value. If the span was inconsistent with the reported value, the CO levels were adjusted to provide a

value that was more consistent with the span. We revised the CO limits based on the results of this analysis.

The final emission limits resulting

from the revised MACT floor calculations are presented in Tables 3 through 6 of this preamble, and compared to the proposed emission

limits.

D. Baseline Emissions, Costs and Impacts Estimation

For the final rule, we have revised the baseline emissions, costs, and impacts to incorporate information provided by

commenters. A discussion of the changes is presented in section V of this preamble. The results of these analyses

are summarized in section VI of this preamble. E. Compliance Requirements

For both the standards, the following changes have been made:

• SSI units must submit (at least 60 days before their initial compliance test date) a monitoring plan to establish that


### 15382 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

their ash handling system will meet the
visible emissions limit on a continuous
basis.

• The alternative to test less frequently (every third year) is being revised to be the following:

Æ If SSI units demonstrate emissions below a specified threshold during two consecutive performance tests, they may test every 3 years instead of annually. Any year that the emission threshold is not met, the SSI must test annually until
the threshold is met over a consecutive 2 year period. The alternative in the standards no longer requires that SSI units establish that they meet the lower thresholds for three consecutive years.

Æ For all pollutants, less frequent testing is allowed if emissions are no greater than an emissions threshold of 75 percent of the emission limit.

Æ For fugitive emissions from ash handling, less frequent testing is allowed as long as visible emissions of combustion ash occur less than or equal to two percent of each hourly observation period (the standard is five percent of each of three hourly observation periods).

• The final rule removes the requirements in the standards to maintain sludge feed rate and moisture content within specified parameters. However, sludge feed rate and sludge moisture content are still required to be monitored during performance test runs, and daily records of sludge feed rate and sludge moisture content are required to be kept.

• At proposal, operating limits were calculated based on a specified percentage of the average parameter value recorded during pollutant performance tests. In the final standards, operating parameter limits are determined on a site-specific basis as the minimum or maximum operating parameter value for the parameter, as applicable, recorded during pollutant performance tests.

• The proposed standards schedule for conducting annual performance tests
was each 10–12 months. This has been changed to specify that performance
tests must be conducted on a calendar year basis (no less than nine calendar
months and no more than 15 calendar months following the previous performance test); and you must complete five performance tests for each such pollutant in each 5-year calendar period.

• The averaging time for demonstrating compliance with the CO CEMS operating parameters has been changed from a 4-hour rolling averaging period to a 24-hr block averaging period. The averaging times for all other operating parameters, except scrubber liquid pH, has been changed from a 4- hour rolling averaging period to a 12- hour block averaging period.

• During each compliance test run, SSI units must be operated at a minimum of 85 percent of their maximum permitted capacity.

F. Definitions

The following definitions have been
revised:

• Process change means a significant permit revision, but only with respect to those pollutant-specific emission units for which the proposed permit revision is applicable, including but not limited

to:

(1) A change in the process employed at the wastewater treatment facility
associated with the affected SSI unit ( e.g., the addition of tertiary treatment at the facility, which changes the method used for disposing of process solids and processing of the sludge prior to incineration).

(2) A change in the air pollution control devices used to comply with the
emission limits for the affected SSI unit ( e.g., change in the sorbent used for activated carbon injection).

• Sewage sludge incineration (SSI)

unit means an incineration unit combusting sewage sludge for the purpose of reducing the volume of the sewage sludge by removing combustible matter. Sewage sludge incineration unit designs include fluidized bed and multiple hearth. A SSI unit also includes, but is not limited to, the sewage sludge feed system, auxiliary fuel feed system, grate system, flue gas system, waste heat recovery equipment, if any, and bottom ash system. The SSI unit includes all ash handling systems connected to the bottom ash handling system. The combustion unit bottom ash system ends at the truck loading station or similar equipment that transfers the ash to final disposal. The SSI unit does not include air pollution control equipment or the stack.

V. Significant Public Comments and Rationale for Changes to the Proposed
Rule

This section contains a brief summary of major comments and responses. EPA received many comments on this subpart covering numerous topics. EPA’s responses to all comments, including those below, can be found in the comment response document for SSI
units in the docket.

A. Legal and Applicability Issues Regulating SSI Under Section 112 vs.

Section 129

Comment: Many commenters
contended that SSI are within the CWA definition of POTW; therefore, according to CAA section 112(e)(5), EPA must regulate SSI units under CAA section 112(d), and not CAA section 129. The commenters emphasized that
SSI units are located within each respective POTW and are wholly integrated into the solids handling and treatment processes at each POTW.

Other commenters stated that SSI units cannot be regulated under CAA section 129 because they are combusting material that is generated by the POTW,
which is neither a commercial or industrial establishment nor the general public as required in CAA section 129(g)(1). The commenters added that, based on the proposed definition of solid waste, even if they had a new point of generation within the POTW where they were generating solid waste, the POTW sewage sludge is from a municipal source and does not pass the broad applicability for solid waste
incineration under CAA section 129.
Another commenter added that CAA section 129(a)(1)(B)–(C) also directs EPA
to set standards for solid waste incineration units combusting municipal waste, but to qualify as a unit combusting municipal waste, the unit
must first be a solid waste incineration
unit. The commenters concluded that
this would not include SSI units.

Several commenters stated that EPA’s determination to regulate SSI units
under CAA section 129 contradicts previous decisions where EPA has stated that regulations were being developed for SSI under CAA section
112. Another commenter stated that
EPA’s revision to the list of source categories under CAA section 112 to
delete SSI units was because there were no major sources in the source category.
One commenter added that EPA’s decision to regulate SSI units under CAA section 129 is based on an overly broad reading of the NRDC case. The
commenter also claimed that SSI units are not within the scope of the
definition of ‘‘ solid waste incineration

unit’’ in section 129 because sewage sludge is not generated by a commercial or industrial establishment or by the general public.

Response: EPA disagrees with the commenter’s assertion that regulation of
SSI units under section 129 is inconsistent with past EPA statements. As explained in the NPRM, EPA issued
emissions standards for POTW in 1999 pursuant to section 112(d), and those
emissions standards did not include standards for SSI units. In the proposed POTW emissions standards, EPA stated
that ‘‘ [s]ewage sludge incineration will be regulated under section 129 of the CAA[.] ’’ See 63 FR 66087 (December 1,


### 15383 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

1998). EPA also explained in the NPRM for today’s action that the EPA’s statements regarding SSI units during its promulgation of emissions standards for OSWI units are squarely in conflict with
the Court’s decision in NRDC v. EPA, 489 F.3d 1250 (D.C. Cir. 2007), which states in pertinent part that any unit that combusts any solid waste at all is subject to CAA section 129. The commenter does not appear to disagree with that conclusion, but instead simply argues that EPA cannot regulate SSI
units under section 129 because it previously stated that it would regulate them under section 112. However, the NRDC decision precludes EPA from doing so. Additionally, section 112(c)(6) requires that EPA promulgate emission standards assuring that sources accounting for not less than 90 percent of the aggregate emissions of each of the HAP identified in section 112(c)(6) are subject to emission standards. EPA has
determined that section 129 source categories can be included to meet our 90 percent obligations. Therefore, EPA
has included SSI units in the section 112(c)(6) list of sources because SSI units are need to meet our 90 percent requirement for mercury. This decision
is documented in the memorandum

‘‘Emission Standards for Meeting the Ninety Percent Requirement under Section 112(c)(6) of the Clean Air Act’’ in the SSI docket (EPA–HQ–OAR–2009– 0559)

Moreover, section 112(e)(5) does not require EPA to issue emissions
standards for SSI units under section 112(d). Rather, it simply governs the
schedule for the issuance of section 112(d) emissions standards for POTW. Section 112(e), titled ‘‘ Schedule for Standards and Review, ’’ generally requires EPA to establish emissions standards for initially listed source categories as expeditiously as practicable, with certain specific deadlines in section 112(e)(1). Section 112(e) further describes how EPA shall prioritize source categories for regulation, and requires EPA to
establish a schedule for issuance of
emissions standards for section 112 listed source categories. Finally, Congress specified a different schedule for POTW in section 112(e)(5), stating
that emissions standards shall be issued no later than November 15, 1995. Thus, section 112(e)(5) does not require EPA to regulate SSI units under section 112(d), but rather simply identifies the date by which EPA must issue
emissions standards for POTW.

Additionally, the commenter’s interpretation of section 112(e)(5) would conflict with section 129(g) and with the DC Circuit’s interpretation of section 129(g) as explained in NRDC v. EPA. Section 129(g) defines ‘‘ solid waste

incineration unit’’ to include any unit combusting any solid waste, and the

Court in NRDC v. EPA rejected EPA’s position that it could choose to regulate certain units, combusting solid waste,
under section 112 instead of under
section 129. Since SSI units do combust solid waste, EPA does not have the
discretion under section 129 to create an exemption for SSI units from the statutory definition of solid waste. The court noted that section 129(g) itself specifies certain units that combust solid waste but are exempt from the definition, and noted that where Congress created such enumerated exemptions, the EPA lacks discretion to
create additional ones.

EPA also disagrees with the
commenter that SSI units do not combust waste from the general public. Sewage sludge clearly originates from the general public, including residential and commercial facilities. Simply
because the waste is treated at a POTW prior to combustion does not change the original source of the sewage sludge.
The commenter refers to a statement in EPA’s 2000 Unified Regulatory Agenda to support its argument. However, the Regulatory Agenda did not represent an Agency interpretation following a notice and comment process. Moreover, as explained above, EPA’s position regarding the section of the Act under which SSI units must be regulated has changed since 2000, in light of the DC
Circuit’s decision in NRDC v. EPA. Finally, EPA notes that its final action
on reconsideration of the OSWI rule did not refer to the source of sewage sludge as a basis for concluding that regulation under section 129 was not required. Instead, as explained above, it referred to discretion the Agency believed it had at the time to choose to regulate certain
solid waste incinerators under section 112—discretion the Agency no longer
believes it has.

The commenter’s reference to
statements made in other Federal Register notices that pre-date the NRDC decision similarly fail to support its argument that EPA must regulate SSI units under section 112. Specifically,
commenters refer to EPA’s inclusion of SSI on the list of area source categories listed under section 112(c)(3) and (k)(3)(B)(ii) of the Act. See 67 FR 70427 (Nov. 22, 2002). However, that listing
does not lead to the conclusion that SSI must be regulated under section 112. First, as explained above, EPA’s interpretation of its authority to regulate SSI has changed following the issuance
of the DC Circuit’s decision in NRDC v. EPA, which occurred after the 2002 listing referred to by the commenter. Additionally, that listing included source categories that would clearly be regulated under section 129, such as
medical waste incinerators and municipal waste combustors, Id. at 70428, because EPA’s regulation of incinerator source categories under section 129 serves towards meeting its statutory obligations under section 112(c)(3) and (k)(3)(B)(ii). Therefore, the
inclusion of SSI on that list does not
indicate that such units must be regulated under section 112.

EPA further disagrees that regulation
of SSI units under section 129 is unnecessary because SSI units are already regulated under section 405 of the CWA and that section 129 regulation will therefore provide no public health or environmental benefit. As explained in section VI of this preamble, today’s action will benefit public health and the environment by achieving reductions of the section 129 pollutants from SSI units beyond those required by regulations issued pursuant to the CWA. Today’s action must be undertaken to comply with the Clean Air Act and the
court decision in NRDC v. EPA. EPA
further notes that section 405 of the CWA expressly provides that nothing in
that section is intended to waive more stringent requirements of any other law. Therefore, Congress clearly did not intend for regulation of SSI units under the CWA to preclude any other regulations, including regulation under

CAA section 129. Overlap with Other
Standards

Comment: Several commenters expressed concern that other types of
solid waste incineration units could be considered SSI units and subject to the SSI standards if they combust any amount of sewage sludge. Some
commenters added that the definition of
a SSI does not have a de minimis level of sewage sludge burned. Other commenters requested clarification on whether SSI units burning non-sludge industrial waste would be subject to
both SSI and CISWI. Some commenters suggested that SSI units be consistent with the MWC standards and provide an exemption for co-fired combustors firing 30 percent or less by weight of sewage sludge.

Commenters suggested that the SSI standards provide exclusions for all
solid waste incineration units that meet the applicability requirements of other CAA section 129 standards, including MWCs regulated under Subparts Ea, Eb, Cb, AAAA, and BBBB. The commenters
noted that the CISWI standards specifically exempted MWC units and other units subject to CAA section 129
standards.


### 15384 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

Several commenters contended that EPA should exempt incineration units subject to hazardous waste combustor regulations and/or hazardous waste management permits under the Solid Waste Disposal Act. The commenters added that CAA section 129(g)(1) states
that a solid waste incineration unit does
not include incinerators or other units required to have a permit under section
3005 of the SWDA. Other commenters requested EPA include an exemption for
hazardous waste combustion units that are affected sources under 40 CFR part 63 subpart EEE.

Response: Section 129 defines solid waste incineration unit to include any unit combusting any solid waste. Therefore, EPA is not setting de

minimus levels for solid waste burned
in incinerators. An incinerator located at a wastewater treatment facility designed to treat domestic sewage sludge that combusts any amount of sewage sludge is subject to the final SSI
standards. We have clarified that the final standards and guidelines do not apply to sewage sludge that is not
burned in a SSI located at a wastewater treatment facility designed to treat domestic sewage sludge. Sewage sludge
that is not burned in a SSI located at a wastewater treatment facility designed to treat domestic sewage sludge is subject to other section 129 standards, such as the CISWI standards (40 CFR part 60, subparts CCCC and DDDD of this part), the OSWI standards (40 CFR part 60, subparts EEEE and FFFF), the MWC standards (40 CFR part 60, subparts Ea, Eb, Cb, AAAA, and BBBB of this part) or the Hazardous Waste Combustor rule (40 CFR part 63 subpart EEE).

Hazardous waste combustion units that are required to have a permit under
CAA section 3005 or the Solid Waste Disposal Act are exempt from CAA section 129 standards per CAA section 129(g)(1), therefore we do not believe an exemption is needed for this rule.

Comment: Several commenters objected to EPA issuing the proposed SSI standards prior to making determinations regarding the definition
of non-hazardous solid waste.

Response: EPA is not making
determination in this rule about the
definition of non-hazardous solid waste.
Section 129 of the CAA states that ‘‘ solid

waste ’’ shall have meaning promulgated by the Administrator under RCRA. Therefore, today’s action is consistentwith using the defintion of nonhazardous secondary materials promulagted RCRA rule, elsewhere in today’s Federal Register.

Comment: Several commenters contended that sewage sludge is not a solid waste, as the CAA defines solid waste by referencing the definition of
solid waste under RCRA. The
commenters added that RCRA excludes sewage sludge in what is commonly referred to as the domestic sewage exclusion (DSE). The exclusion explicitly states that solid waste does
not include solid or dissolved material in domestic sewage.

Response: This comment is not
relevant to EPA’s establishment of
emissions standards for SSI units. Rather, it is relevant to EPA’s proposed
Identification of Non-Hazardous Secondary Materials That Are Solid Waste rule, and is addressed in EPA’s final action on that proposed rule.

B. Subcategories

Comment: Many commenters agreed with the development of separate EG for existing MH and FB units. The commenters also requested adding the same subcategories for the NSPS. The
commenters added that it was inappropriate to consider the best performing FB SSI as the best performing similar source for the MH SSI new source category. They also stated that, as proposed, the NSPS standards would discourage a POTW’s ability to modify existing MH units, including modifications to improve combustion efficiency or boost steam output for electricity generation. Some commenters stated that, by using the best performing FB unit as the basis for the NSPS for MH units, EPA was effectively setting a beyond-the-floor
MACT limit for SSI units without considering any criteria that the statute requires. Other commenters agreed with the decision to use the best-performing
FB unit as the best similar source for the MH SSI source category.

Other commenters requested further subcategorization based on size of the SSI unit, type of sewage sludge incinerated, limited use units, and
distance over which the SSI would need to transport its sludge for disposal.

Response: We have considered the commenters’ concerns and are setting separate standards for FB and MH units
at new sources in the final rule. As discussed in the NPRM, there are two types of incinerators currently used to combust sewage sludge: MH and FB
incinerators. The differences between the two combustor designs result in significant differences in emissions, size of the flue gas stream, ability to handle variability in the feeds, control of temperature and other process variables, auxiliary fuel use and other
characteristics. To reflect the differences in their combustion mechanisms, two subcategories, FB and MH, were developed in the NPRM for new and existing SSI sources.

At proposal for the MH new sourcesubcategory, we considered the bestperforming FB incinerator to be the bestperforming similar source because we were not aware of any new MH sources
that have been constructed in the last 20 years, and information provided by the industry indicates that future units that will be constructed are likely to be FB

incinerators.

We have re-evaluated our decision. Although few MH units have been constructed over the last 20 years, there
is no technical reason that would preclude a source from constructing a MH unit. The same design differences that distinguish existing FB and MH units also apply to new units, and provide a similar basis for subcategorizing between the two types of units. Therefore, we are setting separate standards for MH units at new
and reconstructed sources. Such subcategorization is appropriate based
on the differences between FB and MH units described above, and will also
serve to ensure that MH units do not avoid making modifications that may require them to meet standards based on FB units. We are not subcategorizing SSI units on any other basis because we do not have data to support distinguishing units based on class, type, or size. Without such information, we do not have a basis for concluding that these types of units should be placed in a different subcategory.

C. MACT Floor Analysis

Pollutant-by-Pollutant Approach

Comment: Many commenters objected to setting the MACT floors using a pollutant by pollutant approach because
none of the facilities in EPA’s database can simultaneously meet all the proposed standards. One commenter
stated that EPA’s MACT Floor methodology is supposed to involve

‘‘review of actual emissions data with an appropriate accounting for emissions variability’’ . However, the commenter
contended that EPA fails to follow this guidance in a practical manner in establishing MACT Floors for SSI units and that this results is unrealistically stringent limits that are not achievable for any SSI. Several commenters noted that this was especially true for the new
source standards. Several commenters added that EPA’s pollutant-by-pollutant
basis violates the statute and its own
views of the statute. One commenter
stated that if EPA cannot demonstrate that the top performers can simultaneously meet all standards, EPA has improperly circumvented the


### 15385 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

section 129 for establishing ‘‘beyondthe-floor’’ standards because the ‘‘ floor standards would force industry-wide technological upgrades without consideration of the factors (cost and energy in particular) which Congress
mandated for consideration when establishing beyond-the-floor
standards. ’’

Many commenters specificallymentioned that EPA’s pollutant-bypollutant, lowest emission methodology for setting the CO and NO X standards is
flawed because EPA did not take into
account the inherent conflict in complying with two standards. The
commenters noted that CO and NO X emissions are inversely proportional. The commenters explained that
decreases in CO tend to elevate NO X and vice versa. The commenters added that high temperature combustion with long residence times and high oxygen concentration results in very low CO emissions, and that those same operating conditions favor high NO X emissions. The commenters added that
the conditions used to minimize CO ( i.e., high temperature afterburners) consume more fuel and produce more

CO 2 emissions.

One commenter noted that the SSI
unit with the most advanced control technologies, and those EPA indicated were costed in the impacts analysis,
would not meet the emission limits for all of the pollutants all of the time. The commenter provided an example showing that of 11 of 30 test data points
from the SSI unit in EPA’s database would not comply with the Cd standard, 28 of 30 data points would not comply with the Pb standard, 22 of 30 would not comply with the HCl standard, six of six data points would not comply with the PCDD/PCDF TMB or TEQ, 86 of 105 would not comply with the CO standard, and eight of 15 would not comply with the NO X standard. The
commenter concluded that data variability has not been appropriately
accounted for and that EPA’s method of establishing the MACT floor based on the best performing unit for each pollutant is not reasonable.

Response: We disagree with the commenters who object to setting MACT floors on a pollutant-by pollutant basis. EPA previously has explained that although CAA section 129 does not unambiguously declare that MACT
floors must be established on a pollutant-by-pollutant basis, applying the requirement to set MACT floors based on what has been achieved by the best-performing sources for each of the pollutants covered by CAA section 129 is a reasonable interpretation of EPA’s obligation under that provision (62 FR 48363–64).

EPA interprets the provision in CAA section 129(a)(2) to support establishing
emissions standards based on the actual
emissions of ‘‘the best controlled similar

unit’’ or ‘‘best-performing 12 percent of units in the category’’ for each covered pollutant. Even if we were to conclude that the commenters’ interpretation is equally reasonable under the statute, which we do not, the commenters’ interpretation is certainly not compelled by the statute. We maintain that our interpretation is reasonable under the statute and appropriate given the problems associated with implementing the commenters’ approach.

The rest of CAA section 129 requires

EPA to ‘‘ establish performance standards and other requirements pursuant to section [111] of this title and this section [129] for each category of solid

waste incineration units. ’’ Pursuant to CAA section 129(a)(2), those standards

‘‘ shall reflect the maximum degree of
reduction in emissions of air pollutants listed under section (a)(4)* * *. ’’ (emphasis added). Subsection (a)(4)
then states: ‘‘ The performance standards promulgated under section [111] of this title and this section [129] and applicable to solid waste incineration units shall specify numerical emissions limitations for the following substances or mixtures: PM (total and fine), opacity (as appropriate), sulfur dioxide, hydrogen chloride, oxides of nitrogen, carbon monoxide, lead, Cd, mercury,
and dioxins and dibenzofurans. ’’ Thus, the statute requires EPA to set individual numeric performance
standards based on the maximum degree of reduction in emissions actually achieved for each of nine listed pollutants. Based on this, EPA believes—and has long believed—the statute supports, if not requires, that
MACT floors be derived for each pollutant based on the emission levels achieved for each pollutant. Moreover, although the provisions do not state whether there is to be a separate floor for each pollutant, the fact that Congress singled out these pollutants suggests
that the floor level of control need not be limited by the performance of devices that only control some of these pollutants well.

Looking at the statute as a whole, EPA declared in the 1997 rulemaking for
medical waste incinerators ‘‘ The EPA does not agree that the MACT floors are to be based upon one overall unit’’ (62 FR 48364). Pointing for instance to subsection 129(a)(4), EPA explained:

This provision certainly appears to direct maximum reduction of each specified pollutant. Moreover, although the provisions do not state whether there is to be a separate floor for each pollutant, the fact that Congress singled out these pollutants suggests that the floor level of control need not be limited by the performance of devices that only control some of these pollutants well.

Id.

Since 1997, the courts have consistently repeated that EPA must set
emission standards based on the bestperforming source for each pollutant. See, e.g., Cement Kiln, 255 F.3d 855, 858 (DC Cir.) ( ‘‘ [T]he Agency first sets emission floors for each pollutant and source category * * *. ’’ ). Accordingly, EPA’s pollutant-by-pollutant approach has, as outlined above, been in place
since 1997 for medical waste incinerators, and even earlier for other types of incinerators regulated under

section 129. See, e.g., 59 FR 48198 (September 20, 1994) (municipal waste combustors). In addition, such an approach has been upheld in other

contexts. See, e.g., Chemical Mfrs. Ass’n

v. EPA, 870 F.2d 177, 239 (5th Cir. 1989) (concluding that basing CWA best available technology standards on a pollutant-by-pollutant basis was a rational interpretation of EPA’s obligations under that similar statute). We note that the CAA MACT provisions were fashioned on that CWA program. S. Rep. No. 228, 101st Cong. 2d sess.

133–34.

Further, utilizing the single-unit theory would likely result in EPA setting the standards at levels that could, for some pollutants, actually be
based on emissions limitations achieved by the worst-performing unit, rather
than the best-performing unit, as required by the statute. See 61 FR 173687 (April 19, 1996); 62 FR 48363– 64 (September 15, 1997). For example, if the best performing 12 percent of
facilities for metals did not control
CDD/CDF as well as a different 12 percent of facilities, the floor for PCDD/ PCDF and metals would end up not reflecting best performance. Moreover, a single-unit approach would require EPA to make value judgments as to which pollutant reductions are most critical in working to identify the single unit that reduces emissions of the nine pollutants on an overall best-performing basis. Such value judgments are antithetical to
the command of the statute at the MACT floor stage. It would essentially require EPA to prioritize the nine pollutants
based on the relative risk to human health of each pollutant, a criterion that has no place in the establishment of
MACT floors. Sierra Club v. EPA (Copper Smelters), 353 F.3d 976, 979–80 (DC Cir. 2004).


### 15386 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

The fact that the statute does not contain the phrase ‘‘ for each pollutant’’ does not compel any inference that Congress was sub silentio mandating a
different result when it left the provision ambiguous on this issue. The argument that MACT floors set pollutant-by-pollutant are based on the performance of a hypothetical facility,
so that the limitations are not based on those achieved in practice, just re-begs the question of whether CAA section 129(a)(2) refers to whole facilities or individual pollutants. All of the
emission limitations in this rule reflect actual performance and are achieved in practice.

An interpretation that the floor level of control must be limited by the performance of devices that only control some of these pollutants effectively

‘‘guts the standards ’’ by including worse performers in the averaging process, whereas EPA’s interpretation promotes the evident Congressional objective of having the floor reflect the average performance of best performing sources. Since Congress has not spoken to the precise question at issue, and EPA’s interpretation effectuates statutory goals and policies in a reasonable manner, its interpretation must be upheld. See
Chevron v. NRDC, 467 U.S. 837 (1984).

Commenters made much of the fact that no single facility is presently achieving all of the nine pollutant limits proposed. However, the available information compared to the final standards disputes this assertion. For the final standards, based on the data we have, our estimate of baseline emissions, and the revised emission limits, we are estimating that 155 of 204 existing SSI units can meet standards for all nine pollutants, without installing additional pollution control.
We cannot make this assessment for new sources, because none have been constructed. However, we are not aware of any technical reason that new units
could not install the most advanced pollution control techniques or reduce the pollutant concentrations in the sludge to meet the new source
standards.

We recognize that the pollutant-bypollutant approach for determining the MACT floor can, as it does in this case,
increase the overall cost of the regulation compared to what would result under a unit-based methodology. We interpret CAA section 129 to require
that the MACT floor be determined in this manner, and we believe that Congress did, in fact, intend that sources subject to regulations developed
under CAA section 129 meet emissions limits that are achieved by the best controlled unit for each pollutant, as long as the control systems are compatible with each other. To our knowledge, there is no technical reason why these air pollution control systems
cannot be combined.

Regarding the inverse relationship
between CO and NO X with regard to combustion control, it is incumbent upon the SSI facility to determine
whether combustion conditions can be adjusted to meet both standards and, if not, install NO X controls as necessary ( e.g., SNCR systems, SCR systems, FGR,
or low NO X burners). In the proposed rule, we conjectured reasons why SCR and SNCR were not used or may not be
able to be used at SSI units. While we are not aware of any SSI unit that currently uses SNCR or SCR, we also do not know of technical reason why they
could not be used. Given the limited data available on SSI units with FGR, we could not definitely determine how effective the technology was on SSI units. However, we also do not know of a technical reason why they could not be used, if necessary, to meet NO X limits, and commenters did not provide any reasons they could not be used.

Dataset for the MACT Floor Analysis

Comment: Many commenters urged
EPA to collect more information to set the standards. Many commenters
contended that EPA does not have
sufficient actual emission data from enough SSI units to properly set the
MACT floor. Some commenters contended that the floor-setting provision in section 129 requires them to set the existing floor standards ‘‘based on the best performing 12 percent of sources in the category’’ and not just based on the sources for which they
have information. The commenters
contended that EPA did not have emissions data from the best-performing 12 percent of sources or even from 12 percent of sources. Additionally, the
commenters stated that there is no
evidence that the sources for which EPA collected data are among the top 12%. One commenter added that EPA is using actual data from as little as 4.3 percent of a subcategory (7 of 163 MH units for HCl) to determine how the top 12 percent perform.

Some commenters contended that EPA chose to limit its ICR to just nine entities because collecting information
from ten or more entities would have triggered the PRA obligations and a more rigorous OMB review. The commenters concluded that EPA’s plan
to circumvent the PRA and OMB review resulted in an inadequate dataset for this rulemaking that leaves EPA unable to reliably take the first necessary step in a section 129 rulemaking: To determine which of the SSI units are the best performing sources.

Some commenters also contended that EPA targeted its ICR to the nine POTW expected to have the lowest emissions based on the type of unit and the installed air pollution controls. The
commenters contended that EPA’s targeted approach to collecting data from expected top performers undermines its ability to presume the data is a random sample representative of the entire source category or subcategory. The commenters stated that if the data gathered are not representative at the outset, then the data cannot reliably be used in a statistical equation to predict the
emissions data across the source category or subcategory.

Some commenters noted that in the past, EPA has used permit or other regulatory limits, emission levels, feed rate control, and other information to establish MACT standards. Despite this flexibility, the commenters stated that EPA is proposing to use an ‘‘ actual

emissions ’’ method in the SSI rule, even though it does not have actual emissions for each of the regulated pollutants from
at least 12% of the units.

Another commenter stated that EPA
used emission data from state databases
for an additional nine MHs. The
commenter stated that EPA was instructed by the Court to collect data from the best-performing 12% of existing sources, and EPA needs to justify that the emissions data from the
state databases for the additional nine MHs were the 12% best performing

MHs.

Response: As explained in the preamble to the proposed rule, EPA requested several SSI to conduct emissions testing and provide the results to EPA for purposes of this rulemaking. Specifically, EPA collected information on the best-performing
sources to establish MACT floor standards for SSI. Therefore, EPA sent emissions tests requests under section
114 of the CAA to nine entities that own and operate SSI units. EPA identified SSI units that were expected to be the
best-controlled sources and the best performers for further emissions testing. The Agency acknowledges that this selection methodology targets identifying the best-performing sources rather than selecting a representative sample of sources. However, given the
court-ordered deadline for EPA to issue the final SSI rule, it was not possible to undertake the time-consuming process of sending an ICR to all the affected SSI units consistent with the requirements
of the PRA.


### 15387 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

To select the surveyed owners, EPA reviewed the inventory of SSI units for the control devices being operated, and identified a subset of units expected to
have the lowest emissions based on the type of unit and the installed air pollution controls. These controls generally achieve the most reductions possible for the CAA section 129 pollutants, and thereby allow EPA to identify for each pollutant the units with the lowest emissions. For example, units were selected that operated more than one of the following technologies: Activated carbon injection to reduce Hg and dioxins/furans; RTOs or afterburners to reduce CO and organics; wet ESP to reduce fine particulate; high efficiency scrubbers such as packed bed scrubbers and impingement tray scrubbers to reduce PM, Cd, Pb, particulate Hg, and acid gases such as
HCl and SO 2 ; and units with multiple control devices that could reduce PM, Cd, Pb, particulate Hg, such as venturi
scrubber in combination with impingement scrubbers and wet ESPs or with another particulate control device. The 9 owners or operators selected were from different states in different regions of the country, providing a wide spectrum of sources for sludge generated.

Six of the nine ICR recipients operate MH units, resulting in 13 MH units surveyed. Three of the nine operate FB units, resulting in 7 FB units surveyed. Some owners of multiple units at a facility provided information for less than the total number they operated, e.g. 1 unit instead of 2, because not all units were in operation during the test period.
Of those 20 units from the nine surveyed municipalities, EPA collected
data from 17 units that were in operation (11 MH units and 6 FB units). While testing was being undertaken, the
EPA also collected emission test
information for 9 MH SSI units
collected from state environmental agencies public databases. For some pollutants, the emissions from these supplemental test reports were lower
than those from the nine ICR sources.
The EPA concluded that it was appropriate to use all the emissions information from these test reports in the MACT floor analysis. The EPA also collected many test reports that were older than 15 years. The older reports were determined to not be appropriate for this rulemaking because they were unlikely to represent current emissions performance, due to their age and because they pre-dated required compliance with the CWA part 503 standard. In total, emissions information
were collected from 6 FB units and 20 MH units from facilities responding to the ICR and additional test reports provided by state environmental agencies.

As discussed in the NPRM and background documentation, the EPA conducted a statistical analysis to verify
the minimum number of observations needed to accurately characterize the distribution of the best-performing 12 percent of units in each subcategory.
The results showed that the data utilized by EPA meets or exceeds the number of observations necessary to provide an accurate representation of
that data distributed from the bestperforming 12 percent of the source population. The EPA maintains that the
emissions information that we have collected is adequate to determine the MACT floor for the best-performing sources. The EPA disagrees with the
commenters’ recommendation to use other types of data, such as permits, other regulatory limits, or feed rate
controls with the emissions information
to calculate the MACT floor. The other types of data mentioned do not represent the actual emissions or operation of the unit but are potential values in their permits or limits. Most units are typically operating at lower than permitted levels or emission limits.

Additionally, it would be difficult to incorporate such data into the EPA’s
UPL calculation because the UPL
calculation is based on emission test runs of actual data, rather than limits based on permits. The permit or
emission limits would be on a different basis and potentially skew the MACT
floor UPL calculation.

The EPA has also updated the inventory of sources based on additional data provided in the comment letters. The inventory now contains 204 SSI units, 60 FB units and 144 MH units. Given this change in population, 12 percent of each subcategory are equal to 8 FB units and 18 MH units. Although we do not have any more emissions information than at proposal, the change in inventory results in more than 12 percent of MH units with data for PM and Hg. For these pollutants, we
determined the MACT floor based on the best-performing 12 percent of emissions data, as documented in the
memorandum ‘‘Revised MACT Floor Analysis for the Sewage Sludge Incinerator Source Category’’ in the SSI docket (EPA–HQ–OAR–2009–0559).
EPA solicited additional emission test reports in the NPRM. Although many
commenters summarized the results of
their most recent emission tests when comparing their site-specific emissions to EPA’s baseline emissions, none of the commenters actually provided the emissions test reports. The emission test reports are necessary for the EPA to review the test methods and procedures to ensure consistency with other emissions data, and to verify the tests represent a valid test result that can be used in the MACT floor analysis. Additionally, the test reports provide information necessary to correct the
emissions measured into the units used for the MACT floor analysis. Therefore, these additional test result summaries, without background documentation,
could not be used in the MACT floor
UPL calculation.

Comment: One commenter stated that, to fill the data gap caused by the lack
of actual emissions data from the required number of units in each subcategory, EPA applied statistical analysis to single test run results. Several commenters contended that, in
order to enhance the data available for MACT development, EPA counted each test run as a separate data point.

Some commenters stated that basing a MACT Analysis on test runs, instead of tests, is improper. The commenters
noted that CAA section 129 states that MACT standards for existing sources must be as stringent as the ‘‘ emissions limitation achieved by the best performing 12 percent of units in, the
category. ’’ The commenters added that, assuming that EPA equates the term

‘‘ emissions limitation’’ with the concept of emission level (as often stated by EPA), this clause means that EPA must
use the emission levels that have been
achieved to set the MACT floors. The commenters contended that, under the MACT program, it takes a ‘‘minimum’’ of three test runs to make up a valid
emissions level test. The commenter
stated that a test run is not an accurate measure of the performance of the unit
and should not be used as if it were.
Commenters added that EPA should use
the results of the test for each unit (comprised of at least three test runs) to represent what is being achieved by a

unit.

Several commenters contended that EPA must go back and reset the process
based on 12% of MH and 12% of FBI sources (not individual incinerators).
The commenters added that it is important that individual sources, not units, be utilized because the composition of the sludge varies greatly from source to source and utilizing multiple units at one source skews the data development process and ultimately provides the basis for a
flawed MACT standard at best.

Response: We disagree with the commenters. The 99 percent UPL values were calculated for each pollutant and for each subcategory using the test run


### 15388 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

data for those units in the bestperforming 12 percent. Consistent with EPA’s procedures on other MACT standards, such as HMIWI, CISWI, and boilers, the MACT floor emission limits
were calculated on a run basis since compliance is based on the average of a 3-run test. The 99 percent UPL represents the value which one can expect the mean of future 3-runperformance tests form the bestperforming 12 percent of sources to fall below, with 99 percent confidence, based upon the results of the independent sample observations from the same best-performing sources.

Variability Calculation

For the final rule, as in the NPRM, we are incorporating variability in the
MACT floor calculation for this source category using the 99 percent UPL. We are also following the same procedures for establishing limits and incorporating
non-detect values as discussed in the
NPRM. We have made three revisions to the variability calculation for the final rule. First, we revised the MACT floor variability calculation to incorporate weighted UPL’s for existing FB units. Second, we selected log-normal results
when it is not clear that data are normally distributed. Lastly, we revised the CO limits based on an analysis of the span of the test. The weighted UPL’s and log-normal results are discussed in responses to comments. The revision to the CO limits based on reviewing the CO span was done to correct errors in the CO values provided in test reports

and to be consistent with the calculation

methods used in the CISWI and boilers

rules.

Carbon monoxide values obtained from emission test reports were reviewed to determine whether the span of the test used was capable of accurately reading the reported value. If the span was inconsistent with the reported value, the CO levels were adjusted to provide a value that was more consistent with the span. EPA

Method 10 is structured such that measurement data quality relative to the calibration span of the instrument can

be assessed. For a measurement made using an instrumental test method, the equivalent of the method detection level can be assessed using: a square root formula, the reported calibration span value, and the allowable data quality criteria ( i.e. the allowable calibration error, bias, and drift values). The

estimated CO measurement error resulting from the square root formula was adjusted by a factor of three to be consistent with the methodology EPA applied for non-detect data (where

limits no less than three times the

method detection level were established). In order to develop a basis for
measurement error, instrument calibration spans in available test reports were reviewed. Where no span values could be found, it was assumed
that if the test was conducted on or before May, 2008, the associated CO span would be 1000 ppm, and tests conducted after May 2008 would have a CO span of 100 ppm. This assumption was made because, before revisions were made to Method 10 in May of 2008, it was common that units were using the prescriptive span guidance
that was listed in the old method. The
current version of EPA Method 10 does not include these span requirements but instead requires the tester to choose calibration ranges that reflect the range of expected emission concentrations at the unit. In cases where the reported
emission concentrations were lower than their corresponding measurement errors, the default measurement errors were used in lieu of the reported

concentration.

These revisions are further
documented in the memorandum

‘‘Revised MACT Floor Analysis for the Sewage Sludge Incinerator Source Category’’ in the SSI docket (EPA–HQ– OAR–2009–0559). Table 7 of this preamble shows the revised results of the MACT floor analysis for existing sources, and Table 8 of this preamble
shows the results for new sources.

Comment: One commenter contended
that because CAA section 129 unambiguously requires EPA to set floors reflecting the ‘‘ average ’’ emission level achieved by the best sources, setting floors that instead reflect a UPL
for those sources is unlawful. The commenter, added that by claiming that
it can use the UPL for all sources in the top twelve percent, EPA misreads its authority to consider variability under
the CAA and relevant case law. The commenter explained that, although EPA may consider variability in estimating an individual source’s actual performance over time, nothing in the CAA or the case law even suggests that EPA may account for differences in performance between sources except as section 129 provides, by averaging the emission levels achieved by the sources in the top twelve percent.

Response: In assessing sources’ performance, EPA may consider variability both in identifying which performers are ‘‘best’’ and in assessing their level of performance. Sierra Club

v. EPA (Brick MACT), 479 F. 3d 875, 881–82 (D.C. Cir. 2007); see also
Mossville Environmental Action Now v. EPA, 370 F.3d 1232, 1241–42 (D.C. Cir 2004) (EPA must exercise its judgment,
based on an evaluation of the relevant factors and available data, to determine
the level of emissions control that has been achieved by the best performing sources considering these sources’ operating variability). The Brick MACT
decision indicated that floors for existing sources must reflect the average emission limitation achieved by the best-performing 12 percent of existing
sources. The Brick MACT decision also reiterated that EPA may account for variability in setting floors; however, the Court found that EPA erred in assessing variability because it relied on data from the worst performers to estimate best performers’ variability. The Court held
that ‘‘EPA may not use emission levels of the worst performers to estimate variability of the best performers without a demonstrated relationship
between the two. ’’ 479 F. 3d at 882.

In determining the MACT floor limits, we first determine the floor, which, for existing sources, is the emissions limitation achieved in practice by the average of the top 12 percent of existing sources, or the level achieved in practice by the best controlled similar source for new sources. In this rule, EPA is using lowest emissions limitation as the measure of best performance. We then assess variability of the best performers by using a statistical formula designed to estimate a MACT floor level based on the average of the best performing sources using the expected distribution of future compliance tests. We used the UPL to perform this calculation, as explained below.

Variability can be accounted for using

different statistical methods. For example, recent standards have used the

UL or the UPL to determine the MACT

floor emission limits. A UL is based on

the distribution of the available emission observations ( e.g., test runs), and does not embody a predictive aspect that a UPL does. A prediction interval ( e.g., a UPL) for a future observation is an interval that will, with a specified degree of confidence,contain the next (or some other prespecified) randomly selected observation from a population. In other words, the prediction interval estimates what future values will be, based on present or past background samples taken. Given this definition, the UPL represents the value the mean of three future test run observations (three-run average) can be expected to fall below, based on the results of the independent sample of size (n) from the same population. Therefore, should a future test condition be selected randomly from any of these sources ( i.e., average of three runs), we can be 99 percent confident that the reported level will

fall below a MACT floor emission limit calculated using a UPL. The UPL is an appropriate statistical tool to use in determining variability in the SSI data. For this source category, where there is a limited sampling of the source category and we do not have test data

from all of the SSI units in the best performing 12% for each subcategory, the predictive aspect of the UPL calculation is especially important.

Because the UPL represents the value which we can expect the mean ( i.e., average) of three future observations (3-run average) to fall below, based upon the results of the independent sample size from the same population, the UPL reflects average emissions. The
UPL is also consistent with other recent rulemakings.

Comment: Several commenters asserted that, in setting MACT standards for existing units, EPA pooled and
utilized data from all available test runs for the best performing units without regard to the number of data points
available for each unit. The commenters added that, for all pollutants, the
number of test runs varies from unit to unit. One commenter stated that using data this way biases the statistical results, and ultimately, the standards by over-weighting the performance of the
units that have more data. The commenter suggested that EPA should employ an alternate methodology which
determines the emissions limitation achieved for each best performing unit first, and then averages these limitations to determine the least stringent standard, or MACT floor.

Response: The SSI emissions database
for fluidized bed units contains data
from six units at four facilities. The entities surveyed were requested to provide recent (within the previous 5 years) emissions test reports. Most survey recipients provided only the most recent report. One facility, with three units, provided results of
emissions test conducted for compliance reports spanning a 10-year period. This facility also uses the most advanced pollution controls on their fluidized bed units in the subcategory. This facility constitutes 70 percent of the Cd and Pb data, 90 percent of the CO and Hg data, and 75 percent of the HCl data and PM data. As a result, the existing source MACT floors calculated using the UPL methodology, and all the test run data from the one facility, effectively result in calculating more stringent limits more akin to a new source MACT floor than an existing

12 Heckert, N. A. and Filliben, James J.(2003).

‘‘NIST Handbook 148: DATAPLOT Reference Manual, Volume I: Commands ’’ , National Institute of Standards and Technology Handbook Series, June 2003. [Available at http://www.itl.nist.gov/ div898/software/dataplot/document.html] source MACT floor, because it is based primarily on only the emissions performance of the best-performing single source, rather than the average of the best-performing 12 percent of sources. In order to adequatelyincorporate the emissions from the bestperforming SSI units in the fluidized bed subcategory, a weighted UPL was used for calculating the existing source

MACT floors for the final rule. The weighted UPL is calculated from a weighted mean and weighted variance

as described below. There are many different types of weighting procedures. We have chosen the most straightforward methodology, to base it on the number of data points ( i.e., test runs) from each SSI unit. 12 This weighting scheme ensures that no facility in the MACT best performers pool is over-represented in the computation of the MACT floor. The first step in weighting procedure is to assign a weighting factor to each test run by multiplying each observation for

source i and run j with a weight term,

wij , as shown in Equation 1 of this preamble: Where:

M

i = Number of observations ( i.e., runs) for

source i and

N

= Number of best performing sources in the

MACT pool.

The second step is to calculate the

mean and total variance for the weighted data from the weight terms using Equations 2 and 3 of this preamble:

Where: is the total number of observations in the MACT best performers pool.

When the weights are equal to one, the above equations reduce to those for un-weighted data, as expected. As shown in Equation 4 of this preamble, the weighted mean and weighted
variance are then used in the UPL calculation (discussed in the NPRM) instead of the simple ( i.e., un-weighted)
mean and variance.

For multiple hearth units, there are more emissions data from a larger number of facilities/units. For example,

we have data on Cd and Pb from 11 facilities with 14 units, Hg from 11

facilities with 18 units. The MACT floor calculations are not skewed by one or two units or facilities. Consequently, the MACT floor for existing multiple hearth

units does not need to be calculated using a weighted UPL.

The revisions to the MACT floor methodology are discussed in detail in

the memorandum ‘‘Revised MACT Floor Analysis for the Sewage Sludge Incinerator Source Category’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

Comment: One commenter contended
that EPA should determine the MACT
floor emission limits to be consistent with EPA’s Guidance for Data Quality Assessment Manual, which holds that it is more likely that environmental data are distributed log-normally. The
commenter considered it reasonable to
believe that environmental emission distributions are non-normal, since frequency plots typically show many readings approaching zero and fewer large readings forming an elongated tail to the right. The commenter concluded that normal distributions may exist for certain pollutants where the entire dataset is many standard deviations away from zero, and values are controlled by an air pollution control process with set points and feedback and control loops.

Response: We have reviewed the document referenced and agree with the
commenter that the referenced
document shows that environmental data are more likely to be log-normally distributed than normally distributed. In the proposed rule, two statistical measures, skewness and kurtosis, were
examined to determine if the data used


### 15391 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

to calculate the MACT floor were normally or log-normally distributed. If both the reported values and the natural-log transformed reported values
had skewness and kurtosis statistics that indicated neither were normally distributed, the reported dataset was
selected as the basis of the floor to be
conservative. If the results of the skewness and kurtosis hypothesis tests were mixed for the reported values and the natural log-transformed reported values, the analysis done on the reported data values was chosen to be

conservative.

Based on ‘‘ Guidance for Data Quality
Assessment: Practical Methods for Data Analysis ’’ EPA/600/R–96/084, July 2000, we have modified our assumptions when results of the
skewness and kurtosis tests do notclearly show whether a normal or lognormal distribution better represents the data, or when there are not enough data to complete the skewness and kurtosis tests. In these cases, we have chosen to use the log-normal results for the final
MACT floor calculation.

Comment: Some commenters contended that EPA incorrectly presumes that stack test results account for the full variability of a SSI’s performance. Several commenters stated
that emissions from SSI units are affected not just by control technology but also by other factors including the contents of the sludge that a unit is burning. Many commenters urged EPA to determine the MACT floor limits by incorporating the variability of the sludge contents. The commenters added that the methodology in developing the proposed standards does not take into account that Hg, Cd, Pb, HC1 and SO 2 emissions are a function of the sludge content of Hg, Cd, Pb, chlorine and sulfur. The commenters expressed
concern that the limits were based on test results obtained with sludge containing very low concentration of metals, chlorides, and sulfur. The commenter explained that if the sludge burned during an emissions test was not
at or near the maximum constituent concentration level ( e.g., due to seasonal variability), a new source emission limit
based on these data could not be achieved over the full range of expected normal operating conditions confronted by the best performing source.

The commenters contended that EPA
must consider all available data (including Part 503 data) for the best performing source and use that to establish a variability factor applied to
the stack test data. The commenters added that EPA’s request for metals data during the stack test is insufficient to
account for the full intra-source variability. The commenters added that variability for the compounds not regulated by Part 503 must also be accounted for as well before setting the
new source limit.

The commenters explained that POTW, and their SSI units, are statutorily obligated to manage all of the sewage that enters into the sanitary sewer system, resulting in highly variable and often unpredictable spikes
in concentrations. The commenters
continued that POTW inlet concentrations also vary based on the nature and type of dischargers. The commenters explained that POTW treat wastewater from residential, commercial and industrial dischargers in varying degrees, and pretreatment opportunities also vary because POTW authority to control discharges into the sewer system is limited and the way that authority is exercised varies. The
commenters also noted that the nature of sewage entering the POTW changes
over time as the character of a community changes, the age of the population changes, and commercial and industrial dischargers come and go.
The commenters added that without the use of long-term data to support the level of emission standards, thisvariability makes numeric technologybased limits impractical and infeasible. The commenters also explained that POTW also face significant regional and seasonal variability that is not captured by EPA’s dataset. The commenters stated that initial high flow periods in the spring often scour the sewers and dislodge heavier material that hassettled in the sewer system during lowflow periods, which often results in a spike in metals concentrations ( e.g., Hg, Cd, Pb) in the sewage sludge. The
commenters noted that the ICR stack tests in January and February that were
used for the EPA database would not have captured these events. The
commenter also noted that northern cities that use salt for de-icing roadways experience significant increases in chlorides during the winter months, and high chloride concentrations are known to improve the effectiveness of Hg control at existing wet scrubbers.

Response: The variability analysis is
based on emissions information gathered from nine different facilities
located in nine different states. The
facilities we collected emissions
information from are located in a mix of northern, southern, eastern, and western states. Each facility has its own unique sludge characteristics from different residential and commercial populations. We agree that the emissions data
represents a ‘‘ point in time ’’ . However, combined together, they represent sufficient variation in regions, climates and populations that adequately incorporates variability in wastewater treatment systems across the U.S. We have also incorporated variability using the UPL. The variability analysis based
on the emissions data collected adequately characterizes the potential differences in sludge contents and regional differences. Because we have a
mixture of southern and northern states in the emissions database, we believe that it also adequately considers
differences between cold and warm weather climates. Additionally, we did
not have sufficient information at proposal to consider if it were appropriate to incorporate variability based on sludge content. We requested additional information in the NPRM, but did not receive adequate sampling data from the best-performing sources.

Comment: Some commenters claimed
that EPA’s identification of the relevant best performing units for both existing
and new unit standards is both unlawful and arbitrary, and EPA may not use sources’ control technology as a proxy for their actual performance unless

‘‘ pollution control technology is the only factor determining emission levels. ’’ Cement Kiln Recycling Coalition v. EPA, 255 F.3d 855. 863 (DC Cir. 2001). The commenters stated that, in Cement Kiln Recycling Coalition v. EPA, 255 F.3d 855 (DC Cir 2001) ( ‘‘ CKRC ’’ ), the Court considered Sierra Club’s challenge that
EPA could not set the floors based solely on the performance of one method: Add-on technology. The
commenters added that the Court
remanded the rule because EPA did not consider all of the ways facilities control
emissions. The commenters stated that this requirement is consistent with doing a more complete study as required by section 111 and is antithetical to a methodology based solely on emission levels since setting the floor in this fashion does not require
EPA to examine all methods of control.
The commenters concluded that EPA’s performance data approach in this rule may violate CKRC because EPA did not
check for all methods that sources use to reduce pollution.

Response: EPA disagrees with the commenter who alleges that EPA has not properly identified the best performing SSI units for purposes of calculating MACT floor limits. As explained above, EPA targeted its emissions testing requests to units it believed had the lowest emissions, while accounting for factors such as sludge content and seasonal variation by selecting units in different geographic areas of the country.


### 15392 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

EPA further notes that SSI units currently employ non-technology measures (pollution prevention) to reduce emissions to comply with CWA regulations at 40 CFR part 503. These regulations establish daily average concentration limits for Pb, Cd, and other metals in sewage sludge that is disposed of by incineration. Part 503 also requires that SSI meet the National Emission Standards for Beryllium and Hg in subparts C and E, respectively, of 40 CFR part 61. In order to meet the 40 CFR part 503 standards, facilities are already incorporating management practices and measures to reduce waste and limit the concentration of pollutants in the sludge sent to SSI units, such as segregating contaminated and uncontaminated wastes and establishing discharge limits or pre-treatment
standards for non-domestic users discharging wastewater to POTW. Thus,
the facilities from which EPA received emissions test results are already applying non-technology measures to
reduce emissions.

Comment: One commenter suggested that if EPA employs the statistical limit to set MACT floor emission limits, it should use the 99.9 percent limit. The commenter stated that the 99.9 percent UPL represents a 0.1 percent probability of a failure for individual tests, or a one percent per unit non-compliance probability per annual performance test program. The commenter concluded that this value better encompasses unit emissions variability and represents a manageable risk to the responsible facility operator.

Response: We disagree with the commenters. For the final standards, we maintain the use of 99 percent UPL is appropriate and sufficiently addresses variability in the emissions information. Our analysis of variability is explained
in detail in the memorandum ‘‘Revised MACT Floor Analysis for the Sewage Sludge Incinerator Source Category’’ in the SSI docket (EPA–HQ–OAR–2009– 0559).

Comment: Several commenters opposed an opacity limit of zero percent because opacity is a subjective
measurement and no unit can meet opacity limits of zero at all times. Another commenter suggested that control and monitoring of PM is
sufficient.

Response: We agree that a no visible emissions (zero opacity) limit for combustion processes is impractical for both compliance and enforcement purposes. We also believe that a measurable opacity may or may not be indicative of compliance with a PM emissions limit when applied to multiple sources within the category. That is, an opacity limit applied to one facility could very readily correspond to
a PM emissions level different than that same opacity limit applied to another facility and one or both may be emitting above the PM limit. That opacity limits do not apply very well when wet
control devices are used further confounds the benefit of such regulatory limits. We also agree that there are both CEMS and site-specific parametric monitoring approaches applicable to
various control devices that can be more closely aligned with PM control and compliance with the PM emissions limit than would an opacity limit and opacity monitoring. Instead of establishing opacity limits that may or may not assure compliance with PM emissions limits, the final rules include rigorousrequirements for establishing sitespecific operating limits derived from the results of performance testing. The rules also include a requirement that sources update those enforceable operating limits with each repeated performance test. Re-establishing operating limits periodically will assure that the monitoring will continue to indicate compliance with the PM emissions limits. The rules also provide the source the option of apply CEMS to monitor directly the pollutant of interest in lieu of parametric monitoring. We believe that continuous compliance with operating limits and periodic stack testing to verify the operating limits plus the CEMS option will ensure that
sources demonstrate continuous compliance with the PM emission limits more effectively than would periodic or continuous monitoring of a broadly applicable opacity limit.

Format of the Standards

Comment: Several commenters requested that EPA develop emission limits for some pollutants in different units or to provide a control efficiency alternative. The commenters expressed
concern that the use of concentration limits would not reflect the variability of the unique sludge characteristics of each SSI unit, and may unfairly penalize units with very low or very high feed concentrations of certain pollutants, such as Hg, Cd, or Pb. Some commenters suggested establishing
limits similar to the EPA 503 regulations, which provided emission
limits based on control efficiencies coupled with feed concentration limits.

Response: We did not have sufficient data to set alternative control efficiency
standards or standards in other units at proposal. We requested additional information in the proposal. However, sufficient data were not provided in response to our request for alternative formats to be developed.

D. Baseline Emissions

Comment: Commenters stated that
EPA overestimated baseline emissions
because EPA used incorrect air flow rate parameters, pollution control device efficiencies, sludge feed rates, and operating hours. Many commenters provided stack test data, emission estimates, and corrections to the EPA’s SSI inventory database. Other
commenters noted that EPA used uncorrected flue gas flow rates and flow
rate factors in combination with pollutant concentrations corrected to
seven percent oxygen.

Response: We have incorporated corrections to the inventory and calculation inputs provided by the commenters where applicable. In some cases, commenters did not provide
information sufficient for us to revise the inventory or calculation inputs for the commenter’s facility. For example, commenters may have provided an average concentration for a pollutant, but did not provide run-specific
information that would allow us to
convert the concentration information provided to standardized units (7 percent oxygen). Other commenters may have provided emission rates in pounds per hour, but did not provide vent gas flow rate, oxygen content, or moisture

content to convert to concentration units. None of the commenters provided test reports that would have include this
information.

We have also revised the calculation of baseline emissions by revising the defaults assigned to SSI units where
information was not available. Defaults were necessary to be assigned because,
even after new data were received in comments, a significant number of units did not have data on sludge capacity, flue gas flow rates, etc. A detailed discussion of the methodology used to
estimate baseline emissions for the final standards is presented in the
memorandum ‘‘Revised Estimation of Baseline Emissions from Existing Sewage Sludge Incineration

Units ’’ (EPA–HQ–OAR–2009–0559). The revisions to the inventory and other
corrections resulted in the final rule
baseline emissions shown in Table 9 of this preamble. The table shows a range of emissions for each pollutant. The lower bound represents an estimation of actual emissions based on the actual dry sludge feed rates commenters indicated their units were running. The upper bound represents an estimation of potential emissions if the sludge feed rate was at the dry sludge capacity of each unit. We estimated the potential


### 15393 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

emissions because the amount of wastewater treated (and sludge produced) may vary significantly based on changes in population or sources of wastewater. Facilities have the potential to burn up to their units permitted capacity although they may not be doing so currently.

E. Beyond-the-Floor Analysis

Comment: Several commenters requested that EPA reconsider the beyond-the-floor Hg limit for MH units because baseline Hg emissions were overstated and costs for Hg control were understated. Many of the commenters contended that carbon injection is an unproven technology for SSI units, and is currently used at only one facility
with FB units. The commenters added that the facility is undergoing significant issues with the technology.

Commenters also contended that Hg removal using carbon injection cannot be accomplished with existing PM controls, such as venturi scrubbers, and that FFs would be necessary. The commenters added that the high moisture content in the form of liquid droplets from the incinerator will plug FFs, and additional equipment may be necessary to keep the temperature above the dew point, such as an afterburner.

Response: We have revised the beyond-the-floor analysis to incorporate changes made to the baseline emissions, new facility specific data and inputs provided by commenters, and revised control options. We analyzed several beyond-the-floor controls for the final rule. First, we evaluated the use of an
afterburner for control of CO at MH
units. We then evaluated whether additional control of Hg should be required at MH units. We have reviewed the commenters concerns regarding Hg control technologies and agree that applying carbon injection to existing
scrubbers has not been demonstrated to be effective at removing Hg. For combustion sources that are not SSI, such as boilers, carbon injection in combination with a FF has proven to be highly effective in removing Hg. However, for high moisture flue gas streams, such as emitted from SSI units, the use of FFs is problematic due to plugging/fouling. In order to use carbon injection with a FF with high moisture streams, a waste heat boiler, RTO, or afterburner is necessary to maintain a high enough temperature to keep the stream above the dew point prior to sending the stream to the FF.

Therefore, we next evaluated the combination of using an afterburner, carbon injection, and FF for additional control of Hg at MH units. Additional equipment may also be necessary to reduce the temperature of the flue gas to prevent damage to the fabric filter bags.

Sufficient information was not collected

to estimate this cost. Table 10 of this preamble summarizes the cost for existing SSI units to apply different controls that were analyzed.

The results provided in Tables 10 and 11 of this preamble were calculated using data gathered for each source ( e.g., emissions, vent gas flow rates, controls currently used), as well as default values for emissions, sludge capacity, and vent gas flow rate for sources where

data were unavailable. We estimate that requiring the use of an afterburner for MH units not already having an afterburner could require as much as 1,010 million cubic feet of natural gas a year to be burned, resulting in NO X and CO emissions of 51 and 43 TPY, respectively. We estimate that applying activated carbon injection with a FF and

an afterburner or RTO to all MH units to control Hg and PCDD/PCDF would result in total annualized costs of $138 million dollars (using a discount rate of seven percent) and would achieve Hg

reductions of 0.67–0.89 TPY. The incremental cost-effectiveness of adding afterburners/RTO, activated carbon injection, and FFs to all MH units is estimated to be $80,000 to $100,000 per pound of Hg removed. Costs would increase if equipment necessary to cool the flue gas is also necessary. Therefore, given these factors, we are not finalizing any beyond-the-floor requirements for

SSI units.

We also analyzed going beyond-thefloor to require packed bed scrubbers for

additional HCl and SO 2 reduction, a wet ESP for additional PM, Cd and Pb reduction, and SNCR for additional NO X reduction. We determined that it was not appropriate to go beyond-the-floor to achieve greater reduction of HCl, SO 2 , PM, Cd, Pb, and NO X considering the cost and secondary impacts incurred. Our beyond-the-floor analyses for the

final standards are documented in the

memorandum ‘‘Revised Analysis of Beyond the Maximum Achievable Control Technology (MACT) Floor Controls for Existing SSI Units ’’ (EPA– HQ–OAR–2009–0559). F. Cost and Economic Impacts

Comment: Commenters contended
that EPA had underestimated the cost ofthe proposed rule for the beyond-thefloor option of Hg control as well as for the MACT floor for other pollutants because it only has information for less than 12 percent of the SSI units. The
commenters added that EPA used
information from these limited sources and applied it to remaining sources for which they did not have. The
commenters contended that this results
inaccurate determinations of which units could meet the proposed emission
limits and which could not. The
commenters contended that EPA
overestimated the number of sources that could meet the proposed standards resulting in a significant
underestimation of controls.

Some commenters also contended
that EPAs choices of controls to cost for compliance with the proposed standards were inappropriate for SSI units. Many commenters stated that the high moisture content of flue gas streams in some applications may mean that FFs would not be an appropriate control for PM, Cd, or Pb.

Response: EPA is not prescribing a specific control technology or method. A source is required to meet the final emissions limits in these standards, and has the flexibility to use the control method or technology that is best suited for their individual facility. EPA’s costs are estimated based on technologies we believe may be appropriate for the
sources to meet the emissions limits.

At proposal, and for the final standards, we estimated costs and
emissions reductions based on the best
available information to us. We acknowledge that the inventory database did not have complete
information for all 204 SSI units. Consequently, we developed defaults for flue gas flow rate, hours of operation, sludge capacity, and other inputs for the proposed rule. We have updated our analyses using data provided by the
commenters as summarized in section IV. Summary of Significant Changes Following Proposal and the memorandum titled, ‘‘Post-Proposal SSI Database Revisions and Data Gap Filling Methodology’’ in the docket (EPA–HQ– OAR–2009–0559). However, for a number of inputs, we are still assigning
default values where data were not available for each SSI. For the final rule,
we have correlated some of the defaults to populations served by the facilities in
order to better estimate costs and emission reductions more specifically to each facility. Sources will have the best
idea of the costs of controls for their site specific conditions. For some sources,
the costs and emission reductions estimated by EPA may be higher than what the source estimates, and for others they will be less. EPA’s estimates
are estimates based on the best
information available to us. We also
note that the MACT floor costs and emission reductions, and determination
of the number of sources estimated to require control, estimated for the final
rule are also based on the revised MACT
floor limits.

For the final standards we have also revised the types of controls costed to
meet the MACT floor limits. For SSI that
we estimate will need further control of PM, Cd, or Pb to meet the MACT floor,
we have costed out wet ESP as a more appropriate PM control for high
moisture streams. We have also costed
out SNCR for SSI that we estimate will
need further control of NO X to meet the MACT floor limits. As at proposal, we have costed out packed scrubbers for
SSI that we estimate will need further
control of HCl or SO 2 . At the MACT floor level, we do not estimate that any SSI will need to add control for Hg, PCDD/PCDF, or CO. A detailed
discussion of the costs and emissions
reductions estimates for the final


### 15395 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

standards is provided in the
memorandum ‘‘Revised Cost and
Emission Reduction of the MACT Floor
Level of Control ’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

Comment: Commenters contended that EPA had incorrectly calculated the costs of the landfilling alternative because it used dry tons of sewage sludge instead of wet tons. The
commenters added that wet tons is the appropriate basis of the sludge because even after the dewatering process, the sludge contains 70 to 80 percent moisture. Many of the commenters provided estimates for landfilling sludge from their specific unit. The
commenters added that because of the error, EPA has significantly underestimated the impacts from transporting sludge by truck. Other
commenters added that EPA had not evaluated the negative social impact of hauling sludge to a landfill. Some
commenters added that EPA did not consider the additional costs for specific state landfilling regulations.

Several commenters contended that EPA incorrectly estimated the on-site sludge storage requirements because
calculations were not done on a wet
basis. Commenters added that the cost of the storage units would be significant
and would need to include odor control as well as a settling basin.

Other commenters expressed concern regarding the availability of landfills to POTW needing disposal sites. The
commenters contended there was insufficient landfill capacity to handle the influx of sewage sludge.

Response: We have revised our costs and impacts of the landfill alternative
based on comments received on the proposal and corrections made to the analysis. Table 14 of this preamble
summarizes the revised costs and impacts of this alternative if small
entities choose to landfill rather than incinerate sewage sludge. A detailed discussion of the landfilling alternative analysis is provided in the
memorandum ‘‘Revised Cost and
Emission Reduction of the MACT Floor
Level of Control ’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

Based on the revised impacts, it is unlikely that many sources will find landfilling an appropriate alternative. The selection of a management option for sewage sludge is often a local
decision that is based on environmental protection concerns, community needs, geographic constraints, and economic
conditions. Given a full evaluation of these factors, for some sources, landfilling or land treatment may be a better management option than

incineration. G. Startup, Shutdown, and Malfunction

Comment: Numerous commenters disagreed with EPA’s proposed language requiring facilities to meet the proposed
SSI standards ‘‘ at all times ’’ because it would be difficult to comply with certain proposed emission limits during startup and shutdown. Many of these commenters were specifically concerned about not being able to meet the proposed CO concentration limit upon startup of a SSI because when a heat up burner system is fired into a cold vessel, the flame tip is quenched before the combustion is completed creating a small flow of CO. One
commenter contended that EPA is proposing a new source CO standard without any evidence that it can be achieved during startup, shutdown, or malfunction. This commenter provided an example of CO data from one
hazardous waste combustor that averaged 2.2 ppmv during normal operations but averaged 48.6 ppmv during startup, 40.5 ppmv during shutdown, and 815.5 during
malfunctions. The commenters stated that absolute pollutant levels tend to increase during startup and shutdown due to incomplete combustion that is unavoidable at lower temperatures, and
noted that the influence of unstable combustion may be more pronounced during shutdowns as the incinerator combusts the remaining sewage sludge
for 30 minutes or more. The
commenters recommended that EPA account for situations where higher emissions occur during the time it takes to bring control equipment from startup to steady-state operations.

Response: At this time, we are not promulgating a separate emission standard for the source category that applies during periods of startup and
shutdown. We do not have data that would allow us to set a separate standard during periods of startup and shutdown. We requested information in the NPRM. However, no data were provided. Based on the information available at this time, we believe that
SSI units will be able to meet the emission limits during periods of startup. Units we have information on use natural gas, landfill gas, or distillate
oil to start the unit and add waste once
the unit has reached combustion temperatures. Emissions from burning natural gas, landfill gas or distillate fuel oil are expected to generally be lower than from burning solid wastes. Emissions during periods of shutdown are also generally lower than emissions during normal operations because the
materials in the incinerator would be almost fully combusted before shutdown occurs. Furthermore, the approach for establishing MACT floors
for SSI units ranked individual SSI units based on actual performance for each pollutant and subcategory, with an appropriate accounting of emissions variability. Because we accounted for emissions variability, we believe we have adequately addressed any minor variability that may potentially occur during startup or shutdown.

Periods of startup, normal operations, and shutdown are all predictable and routine aspects of a source’s operations. However, by contrast, EPA has
determined that malfunctions should not be viewed as a distinct operating mode and, therefore, any emissions that
occur at such times were not needed to be factored into development of CAA section 129 standards, which, once promulgated, apply at all times. We note that continuous compliance is demonstrated using continuous parametric monitoring, except for CO
from new sources. CO CEMS are required for new source using a 24-hour block average.

Comment: Some commenters argued that EPA incorrectly claims that its authority to prescribe unique standards for SSM periods is constrained by Sierra
Club v. EPA, 551 F.3d 1019 (DC Cir. 2008). These commenters stated that EPA has failed to account adequately for emissions that occur during SSM periods. One commenter contended that the Sierra Club decision interpreted
CAA section 112, not CAA section 129 (which incorporates, by reference, CAA section 111), and pointed out that this interpretation is not merely a technical distinction. The commenter pointed out that since 1977, EPA has exempted emissions during SSM events from compliance with NSPS under CAA section 111 (referenced 40 CFR 60.8(c)). The commenter argued that Congress enacted the continuous basis language in section 302(k) knowing that EPA‘s
emissions standards under section 111 exempted SSM periods, and pointed out that there is nothing in the legislative history of the 1977 amendments to the CAA that suggests congress intended to overturn that practice.

Response: As explained above, EPA believes the reasoning in the DC
Circuit’s decision in Sierra Club v. EPA applies equally to section 129. Additionally, EPA explains above the reasons it is not establishing different emissions standards for periods of startup, shutdown, and malfunction.

H. Compliance Requirements

Comment: Several commenters indicated that the proposed operating parameter ranges for minimum pressure


### 15396 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

drop across a wet scrubber, minimum scrubber liquid flow rate, minimum scrubber liquid pH, and minimum combustion temperature (or minimum afterburner temperature) would not be achievable. They explained that these ranges are too narrow and that they will be inconsistent with the operating standards already required by 40 CFR part 60 subpart O, 40 CFR part 503, and state permits. Two commenters agreed with the proposed operating parameter

ranges.

Response: The EPA reviewed the information provided by the
commenters and determined that proposed procedure for establishing the operating ranges ( i.e., calculated as the average of three test runs and as 90 percent of the minimum value recorded during the applicable performance tests) may be too restrictive on control device operations in terms of energy or other operating needs. We determined that the operating limits should be more appropriately based on values recorded during the performance test runs. The final rule requires that operating limits be established on a site-specific basis as the minimum (or maximum, as appropriate) operating parameter value measured during the performance test. This approach has been incorporated into the final rule for all operating parameters and will result in achievable operating ranges that will ensure that the control devices used for compliance will be operated to achieve continuous compliance with the emissions limits.

Comment: Many commenters argued that the proposed operating range for sludge feed rate would not be achievable, that it results in the EPA changing the current state-permitted maximum sludge feed rate, and that it
could force SSI units to conduct performance tests at maximum rated capacity. They explained that the proposed approach fails to take into
account the normal feed condition and rate variation that occur on a daily and
seasonal basis. A few commenters suggested that charging a SSI at 75 percent to 90 percent of its rated capacity results in a steadier state of
control and more efficient combustion of the sludge.

Many commenters indicated that the proposed operating range for sludge
moisture content would not be
achievable and that EPA does not need sludge moisture content to determine whether SSI units are in compliance with their emission limits. They explained that sludge moisture is very sensitive to the type of dewatering equipment used, seasonal changes in the sewage or sludge received by a SSI, temperature changes, the biological systems that treat the sewage, and to operational changes, and that these changes cannot always be anticipated and are not always immediately
correctable.

Response: The EPA reviewed its decision at proposal to require that SSI units maintain the sludge feed rate and sludge moisture content of the incinerated sludge within specified ranges. We determined that the operating limit for temperature of the combustion chamber (or afterburner temperature) is sufficient to ensure good combustion practice, and that moisture
content is not needed to establish that SSI units are in compliance with their emission limits. If a SSI has a higher moisture content, the SSI will need to use more fuel to comply with their operating limit for temperature of the combustion chamber. We are no longer requiring that SSI units maintain sludge moisture content within specified ranges. We are also no longer requiring SSI units to maintain sludge feed rates within specified ranges due to the seasonal variability at wastewater treatment plants. Sludge feed rate information is necessary during performance test runs to establish that SSI units are in compliance with the new requirement that they conduct performance tests at 85 percent capacity. We are retaining the requirement to keep daily records of sludge feed rates and moisture contents, as SSI units should already be keeping records of these parameters, and this
information will be useful in establishing representative operating
limitations for a SSI unit.

EPA added a requirement that performance tests be conducted at 85 percent of the permitted maximum capacity. This level has been selected based on the performance test operating information provided by the commenters and previous EPA
standards.

Comment: A few commenters indicated that the 4-hour rolling averaging period selected in the proposed rule for determining compliance with the operating parameters and CO limit was more
burdensome and difficult to achieve. They explained that the recordkeeping and compliance burden is less if the averaging period for CEMS and CPMS
are both based on a 24-hour block average. They also explained that the proposed CO limit on a 4-hour rolling average basis would be unachievable
with MH incinerators and difficult to
achieve with FB incinerators.

Response: The EPA has determined that a 24-hour block averaging period for compliance with the CO CEMS requirement for new sources will provide a sufficient indication of compliance and will allow more flexibility for facilities. Additionally, the proposed CO emission guidelines limit of 7.4 ppm for existing fluidized bed SSI units has changed in the final guidelines to 27 ppm, and this change
is discussed in Section IV of this preamble. We have also revised the averaging periods for all other operating parameters, except scrubber liquid pH, to be on a 12-hour block average instead of a 4-hour rolling average basis in order to relate the averaging time for operating
limits to the duration of the performance tests ( e.g., a three run test of 4 hour test runs would equal a 12- hour averaging time). For scrubber liquid pH, we chose 3-hour averages to be consistent with the performance test duration for acid gas scrubbers.

In the final rule, we are also not incorporating the alternative THC compliance requirement. Section 129 requires that limits be set for each of the 9 regulated pollutants. Surrogates, such as THC, cannot be used in place of the regulated pollutants.

Comment: Many commenters disagreed with the requirement in the proposed rule for annual testing, and argued that annual testing of each SSI is not needed to demonstrate compliance, too costly, and inconsistent with current Title V permits. They also argued that Method 22 compliance testing for fugitive ash emissions is not feasible or difficult to conduct due to space constraints, and that many FB
incinerators utilize wet ash removal systems that do not require annual testing. They explained that the cost for emissions testing may be significantly higher than the proposed cost of $61,000 per unit. They further explained that Title V permits require
facilities to test each of its SSI units once per 5 years. They pointed out that current management practices and strict health-based sludge content limits
under the CWA section 405 and the CAA 40 CFR part 503 regulations will help ensure that SSI units are in compliance with their emission limits. One commenter pointed out that the proposed compliance schedule of every 10 to 12 months will essentially shorten the testing year by one month each year.

Response: The proposed standards included provisions for less frequent testing. In the final standards, EPA has revised these provisions, making it easier for facilities to qualify for less frequent testing, allowing less frequent testing for more pollutants, and ensuring that facilities that do less frequent testing are well below their emission limits. In the final standards,


### 15397 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

owners or operators are required to establish that emissions of a given pollutant are under a specified threshold for two consecutive years, rather than 3 years as proposed, to qualify for less frequent testing for that pollutant. We have also extended the option to do less frequent testing to PCDD/PCDF and fugitive ash emissions testing. The threshold is 75 percent of
the emission limit for each of the nine regulated pollutants. In order to allow a decrease in testing frequency, EPA must
have assurance that SSI units can meet a more stringent threshold than the limits. This is particularly necessary because of the variability in sludge that
may occur at wastewater treatment facilities. Additionally, in the final standards we are also providing assurance that the SSI unit is being operated properly and emission limits are being met continuously by requiring stringent parametric monitoring requirements. Specifically, exceedances
of the minimum or maximum values established during the performance tests are considered deviations. For fugitive emissions from ash handling, owners or operators must demonstrate that visible emissions occur no more than 2 percent of the time during each Method 22 1- hour observation period. This allowance for fugitive ash emissions has been
included in the final standards with a new requirement that all facilities must submit a monitoring plan at least 60 days before their initial compliance test to establish that their ash handling system will continuously meet the
visible emissions limit.

Additionally, to allow facilities more flexibility regarding their test dates, to
ensure that facilities are not forced to test at intervals less than 12 months, and to ensure that facilities are testing once per year, we have revised the testing schedule provisions. In the final standards, performance tests (except for pollutants that qualify for less frequent testing) must be conducted on a calendar year basis (no less than nine
calendar months and no more than 15 calendar months following the previous performance test); and facilities must complete five performance tests per pollutant in each 5-year calendar period.

Comment: Many commenters requested that the definition of ‘‘ process change ’’ be revised to exclude the provision that a process change include
an increase in the allowable wastewater received from an industrial source. They pointed out that any such increase would trigger a performance test, as required by the proposed standards, and
that such increases did not warrant a retest. They explained that industrial discharges often constitute only a small percentage of total influent flow ( e.g., 3.5 percent, four to eight percent), that such discharges are sometimes from sources that do not discharge the pollutants regulated by the proposed NSPS and guidelines ( e.g., food processing facilities), that some merchant SSI facilities regularly receive variable amounts of sludge from other regional wastewater treatment plants and POTW, and that it is difficult for impossible to anticipate some industrial load changes ahead of time. Several commenters argued that this proposed requirement would be redundant to the National Pretreatment Regulations at 40 CFR part 403, which are incorporated
into their SSI’s National Pollutant Discharge Elimination System (NPDES) permit, which require them to establish local limits on industrial discharges to prevent interference with sludge processes, use, and disposal. The commenters anticipate that they would establish similar limits to prevent noncompliance with the final emission limits. A few commenters suggested that the proposed provision for industrial discharges is vague and open to interpretation.

Response: The EPA reviewed the
definition of ‘‘ process change ’’ and agrees with the commenters that there
are some situations where an increase in
the allowable wastewater received from an industrial source should not trigger a performance test. We have revised the
definition of ‘‘ process change ’’ to more specifically and clearly identify the type of process change that will trigger a performance test. The revised definition
identifies a ‘‘ process change ’’ as pollutant-specific and as including only situations where the SSI has undergone a significant permit revision. This
revision will ensure that facilities retest whenever they have a significant change in the process that could trigger higher emissions of a given pollutant.

Comment: Several commenters requested EPA clarify what equipment are included as part of the SSI unit. The commenters stated that the proposed rules do not specify the equipment and without clarification, a SSI unit couldbe interpreted inconsistently or overbroadly. Commenters requested clarification regarding whether the

‘‘modification’’ (which refers to an ‘‘ SSI

unit’’ ) applies to the multiple hearth or
fluid bed ‘‘reactor’’ or whether it includes the entire system including all air emission controls and auxiliary equipment.

Response: We agree that the definition of the SSI unit in the proposed rule was unclear as to what equipment
constitutes the SSI unit. We have revised the definition of SSI unit in the
final rule. A SSI unit means an incineration unit combusting sewage sludge for the purpose of reducing the volume of the sewage sludge by removing combustible matter. Sewage sludge incineration unit designs include fluidized bed and multiple hearth. We
have clarified that a SSI unit also includes, but is not limited to, the sewage sludge feed system, auxiliary fuel feed system, grate system, flue gas system, waste heat recovery equipment, if any, and bottom ash system. The SSI unit includes all ash handling systems connected to the bottom ash handling system. The combustion unit bottom ash system ends at the truck loading station or similar equipment that transfers the ash to final disposal. The SSI unit does not include air pollution control equipment or the stack.

VI. Impacts of the Final Action

As discussed in sections IV and V of this preamble, we have made several revisions to the impacts analyses for the final rules. We have incorporated revisions to the variability calculation. These revisions include: incorporating weighted UPL’s for existing FB units, selecting log-normal results when it is not clear that data are normally distributed, and revising CO limits based on an analysis of the span of the test. The result of these changes
increased UPL values for most pollutants.

Additionally, we have incorporated corrections to the inventory and calculation inputs provided by the commenters where applicable. We have
also revised the calculation of baseline emissions by revising the defaults assigned to SSI units where information was not available. These changes resulted in decreasing the baseline emissions for each of the pollutants. The
combination of increase UPL and
decreased baseline emissions resulted in
less SSI units estimated to need
additional control to meet the MACT
floor limits.

For the final rules, we also selected
the MACT floor level of control for both subcategories instead of selecting a beyond-the-floor requirement.

For the final rules we have also revised the types of controls costed to
meet the MACT floor limits. For SSI that
we estimate will need further control of PM, Cd, or Pb to meet the MACT floor,
we have costed out wet ESP as a more appropriate PM control for high
moisture streams. We have also costed
out SNCR for SSI that we estimate will
need further control of NO X to meet the MACT floor limits. As at proposal, we have costed out packed-bed scrubbers

for SSI that we estimate will need

further control of HCl or SO 2

. A. Impacts of the Final Action for Existing Units

1. What are the primary air impacts?

We have estimated the potential emission reductions that may be realized through implementation of the
final emission limits. As discussed in section V of this preamble, we have
revised the estimation of baseline
emissions and emission reductions to present a range to show the variability
in the emission calculations between estimated actual and estimated potential sludge feed rates. Table 12 of this preamble summarizes the emission reductions for MACT compliance for each pollutant. The analysis is
documented in the memorandum

‘‘Revised Analysis of Beyond the
Maximum Achievable Control Technology (MACT) Floor Controls for Existing SSI Units ’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

2. What are the water and solid waste impacts?

We anticipate affected sources will need to apply additional controls to meet the proposed emission limits. These controls may utilize water, such as wet scrubbers, which would need to
be treated. We estimate an annual requirement of 234 million gallons per year of additional wastewater will be generated as a result of operating
additional controls or increased
sorbents.

The analysis is documented in the
memorandum ‘‘Revised Secondary Impacts for the Sewage Sludge Incineration Source Category’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

3. What are the energy impacts?

The energy impacts associated with meeting the proposed emission limits consist primarily of additional electricity needs to run added or improved air pollution control devices. For example, increased scrubber pump horsepower may cause slight increases in electricity consumption; sorbent injection controls would likewise require electricity to power pumps and motors. We anticipate that an additional 5,420 megawatt-hours per year will be required for the additional and improved control devices. The analysis
is documented in the memorandum

‘‘Revised Secondary Impacts for the Sewage Sludge Incineration Source Category’’ in the SSI docket (EPA–HQ– OAR–2009–0559). 4. What are the secondary air impacts?

For SSI units adding controls to meet the final emission limits, we anticipate very minor secondary air impacts. The combustion of fuel needed to generate additional electricity will yield slight increases in emissions, including NO X , CO, PM and SO 2 and an increase in CO 2 emissions. Since NO X and SO 2 are covered by capped emissions trading programs, and methodological limitations prevent us from quantifying the change in CO and PM, we do not estimate an increase in secondary air impacts for this rule from additional electricity demand.

5. What are the cost and economic impacts?

We have estimated compliance costs for all existing units to add the necessary controls, monitoring equipment, inspections, recordkeeping, and reporting requirements to comply with Option 1 ( i.e., the selected SSI standards). Based on this analysis, we anticipate an overall total capital investment of $55 million with an associated total annualized cost of $18 million, in 2008 dollars (and using a discount rate of seven percent), as shown in Table 13 of this preamble. We anticipate that owner/operators will need to install one or more air pollution
control devices for 43 of the 204 affected
units to meet the final emission limits. The analysis is documented in the
memorandum ‘‘Revised Analysis of Beyond the Maximum Achievable Control Technology (MACT) Floor Controls for Existing SSI Units ’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

Analysis of Alternative Sewage Sludge Disposal. At proposal, we evaluated landfilling as an alternative disposal
method. We have revised our costs and impacts of this alternative based on comments received on the proposal and corrections made to the analysis. Table 14 of this preamble summarizes the revised costs and impacts of this
alternative if small entities choose to landfill rather than incinerate sewage sludge. A detailed discussion of the landfilling alternative analysis is provided in the memorandum ‘‘Revised
Cost and Emission Reduction of the
MACT Floor Level of Control ’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

Based on the revised impacts, it is unlikely that many sources will find landfilling an appropriate alternative. However, the selection of a management option for sewage sludge is often a local

conditions. Given a full evaluation of these factors, for some sources, landfilling or land treatment may be a better management option than

incineration.

B. Impacts of the Final Action for New

Units

As discussed in the proposal, based
on trends of SSI units constructed and replaced, technical advantages of FB incinerators, and information provided by the industry on likely units constructed, we believe that new SSI units constructed are likely to be FB

incinerators.

1. What are the primary air impacts?

We have estimated the potential emission reductions that may be realized through implementation of the
final emission limits on two new FB incinerators potentially being constructed in the next 5 years. Table 15 of this preamble summarizes these
emission reductions for MACT compliance for each pollutant from two new FB incinerators. The analysis is
documented in the memorandum

‘‘Revised Estimation of Impacts for New
Units Constructed Within 5 Years After Promulgation of the SSI NSPS ’’ in the SSI docket (EPA–HQ–OAR–2009–0559).

We anticipate affected sources would need to apply controls in addition to what they would have planned to
include in the absence of this rule to
meet the final emission limits. These controls may utilize water, such as wet scrubbers, which would need to be
treated. We estimate an annual requirement of 8.6 million gallons per year of additional wastewater will be generated as a result of operating
additional controls or increased sorbents for the two new units expected to come on-line in the next 5 years. The analysis is documented in the
memorandum ‘‘Revised Analysis of Secondary Impacts for the Sewage Sludge Incineration Source Category’’ in the SSI docket (EPA–HQ–OAR–2009– 0559).

Likewise, the application of PM controls results in particulate collected that would require disposal. Furthermore, activated carbon injection may be used by some sources, which would result in solid waste needing disposal. The annual amounts of solid waste that will require disposal are anticipated to be approximately 34 TPY from activated carbon injection for the

two units.

3. What are the energy impacts?

The energy impacts associated with meeting the final emission limits would consist primarily of additional electricity needs to run added or improved air pollution control devices. For example, increased scrubber pump horsepower may cause slight increases in electricity consumption. Sorbent injection controls would likewise require electricity to power pumps and motors. By our estimate, we anticipate that an additional 300 megawatt-hours per year will be required for the additional and improved control
devices for the two new units modeled to come on-line in the next 5 years. The analysis is documented in the
memorandum ‘‘Revised Analysis of Secondary Impacts for the Sewage Sludge Incineration Source Category Analysis of New Units for the Sewage Sludge Incineration Source Category’’ in the SSI docket (EPA–HQ–OAR–2009– 0559).

4. What are the secondary air impacts?

For SSI units adding controls to meet the final emission limits, we anticipate very minor secondary air impacts. The analysis is documented in the
memorandum ‘‘Revised Analysis of Secondary Impacts for the Sewage Sludge Incineration Source Category. ’’ 5. What are the cost impacts?

We have estimated compliance costs for new SSI units coming on-line in the next 5 years. This analysis is based on a model plant, the assumption that two
new units will come on-line and will add the necessary controls, monitoring equipment, inspections, recordkeeping, and reporting requirements to comply
with the final SSI standards. Based on this analysis, we anticipate an overall total capital investment of $8 million (2008$) with an associated total annualized cost of $2 million (2008$ and using a seven percent discount rate). This analysis assumes that new SSI units constructed are only FB

incinerators.

VII. Statutory and Executive Order

Reviews

A. Executive Order 12866 and 13563: Regulatory Planning and Review

Under Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and EO 13563 (76 FR 3821, January 21, 2011),
this action is a ‘‘ significant regulatory

action’’ because it was likely to have an annual effect on the economy of $100 million or more based on the proposed standards. However, the cost of the final standards are no longer likely to have an annual effect on the economy of $100 million or more. Despite the change in costs, EPA submitted this action to the Office of Management and Budget (OMB) for review under EOs 12866 and 13563 and any changes made in response to OMB recommendations
have been documented in the docket for this action. Although EPA prepared a RIA of the potential costs and benefits associated with the proposed standards we are simply updating the RIA rather than revising it.

A RIA was prepared in September of 2010 for the proposed Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Sewage Sludge Incineration Units. However, based on the lower
costs associated with the selected
alternative in this final action we are providing an update of the RIA rather than completely revising the RIA. Within this update, we are providing updated costs and benefits of the controls analyzed and have provided a comparison of the selected controls with
the alternatives. 13 While the characteristics of the controls analyzed have changed, we have also provided a comparison of the costs and benefits of


### 15400 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

the proposed controls analyzed with the
selected alternative in this final action. A summary of the differences are presented below.

• Costs for the selected controls analyzed for promulgation are 80%
lower and benefits are 81% lower than they were for the selected controls analyzed for proposal.

• Because the regulated sewage sludge incineration is a government provided service that does not involve a market, no price, quantity, or employment impacts were estimated for the proposal RIA. The economic impact analysis focused on the comparison of control cost to total governmental
revenue. Because the costs are 80% lower for the selected controls analyzed for promulgation compared to the proposed controls analyzed, the control costs are expected to be a smaller portion of government revenues for the selected controls for promulgation than they were for the proposed controls.

• Because of insufficient information, employment changes due to the requirements for operating and maintaining control equipment were not estimated. Also, we did not have the information needed to estimate any labor changes related to governmental
decisions to switch from incineration to landfilling.

• Monetized benefits are greater than costs for the selected option by $3 million to $34 million at three percent and $1 million to $29 million at seven percent. The benefits from reducing exposure to HAP, direct exposure to

NO X and SO 2 , ecosystem effects, and visibility impairment have not been monetized, including reducing 19 tons of HCl, 4 pounds of Hg, 2,400 pounds of Pb, and 1,000 pounds of Cd.

B. Paperwork Reduction Act

The information collection requirements in this rule have been submitted for approval to the OMB under the Paperwork Reduction Act, 44

U.S.C. 3501 et seq. The information collection requirements are not enforceable until OMB approves them. The ICR documents prepared by EPA have been assigned EPA ICR number 2369.02 for subpart LLLL, and 2403.02 for subpart MMMM.

The recordkeeping and reporting requirements in this rule are based on the information collection requirements
in CAA section 129 and EPA’s NSPS General Provisions (40 CFR part 60, subpart A). The recordkeeping and reporting requirements in the General Provisions are mandatory pursuant to CAA section 114 (42 U.S.C. 7414). All
information other than emissions data submitted to EPA pursuant to the information collection requirements for which a claim of confidentiality is made is safeguarded according to CAA section 114(c) and EPA’s implementing regulations at 40 CFR part 2, subpart B.

The requirements in this action result in industry recordkeeping and reporting
burden associated with review of the
amendments for all SSI and initial and annual compliance with the emission limits using EPA approved emissions
test methods. The burden also includes continuous parameter monitoring and annual inspections of air pollution control devices that may be used to meet the emission limits. Operators are required to obtain qualification and complete annual training. New units are also required to submit a report prior to construction, including a siting analysis.

When a malfunction occurs, sources must report them according to the applicable reporting requirements of Subparts LLLL and MMMM. An affirmative defense to civil penalties for
exceedances of emission limits that are caused by malfunctions is available to a
source if it can demonstrate that certain criteria and requirements are satisfied.
The criteria ensure that the affirmative defense is available only where the
event that causes an exceedance of the
emission limit meets the narrow
definition of malfunction in 40 CFR 60.2 (sudden, infrequent, not reasonably preventable and not caused by poor maintenance and or careless operation) and where the source took necessary

actions to minimize emissions. In addition, the source must meet certain notification and reporting requirements. For example, the source must prepare a written root cause analysis and submit a written report to the Administrator documenting that it has met the conditions and requirements for
assertion of the affirmative defense.

To provide the public with an estimate of the relative magnitude of the
burden associated with an assertion of the affirmative defense position adopted by a source, EPA provides an administrative adjustment to this ICR that shows what the notification, recordkeeping and reporting requirements associated with the
assertion of the affirmative defense might entail. EPA’s estimate for the required notification, reports and records, including the root cause analysis, totals $3,141 and is based on the time and effort required of a source to review relevant data, interview plant employees, and document the events surrounding a malfunction that has
caused an exceedance of an emission
limit. The estimate also includes time to produce and retain the record and reports for submission to EPA. EPA provides this illustrative estimate of this burden because these costs are only
incurred if there has been a violation and a source chooses to take advantage
of the affirmative defense.

The annual average burden associated with the emission guidelines over the first 3 years following promulgation is estimated to be $9.6 million. This includes 39,350 hours at a total annual labor cost of $2.2 million and total annualized capital/startup and operation and maintenance costs of $7.4 million per year, associated with the monitoring requirements, storage of data and reports and photocopying and postage over the 3-year period of the ICR. The annual inspection costs are included under the recordkeeping and reporting labor costs

The annual average burden associated with the NSPS over the first 3 years following promulgation is estimated to
involve 701 hours at a total annual labor cost of $40,000. The total annualized capital/startup costs are estimated at $232,000 per year. This gives a cumulative annual burden of $272,000 per year for the NSPS. Burden is defined at 5 CFR 1320.3(b).

An Agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it currently displays a valid OMB
control number. The OMB control numbers for EPA’s regulations in 40 CFR are listed in 40 CFR part 9. When this ICR is approved by OMB, the Agency will publish a technical amendment to 40 CFR part 9 in the Federal Register to display the OMB control number for the approved information collection requirements
contained in this final.

C. Regulatory Flexibility Act

The RFA generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements
under the Administrative Procedures Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on
a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

For purposes of assessing the impacts of this action on small entities, a small entity is defined as follows: (1) A small business as defined by the SBA regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district, or special district with a population of less than 50,000; or (3) asmall organization that is any not-forprofit enterprise that is independentlyowned and operated and is not
dominant in its field.

In the proposal, we certified that there would not be a significant economic impact on a substantial number of small entities. The economic analysis conducted at proposal identified 18
small entities none of which had costrevenue-ratios greater than one percent. The cost analysis for the final standards showed a significant decrease (35 to 98 percent) in all costs for 11 of the 18
small entities. The cost-revenue-ratios were again estimated using the costs for
the final rule and the same revenue estimates used in the proposal screening analysis. The revenue estimates were obtained using census average per capita revenue numbers ($1,696 for entities with populations between 10 thousand and 25 thousand and $1,677 for entities with populations between 25 thousand and 50 thousand) The resulting cost-revenue-ratios ranged
between 0.04% and 0.5. Thus all costrevenue-ratios were well below 1%. Therefore, we consider the final rule to


### 15402 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

have no significant impact on a
substantial number of small entities.

After considering the economic impacts of this final rule on small entities, I certify that this action will not have a significant economic impact on
a substantial number of small entities.
None of the 18 small entities has costrevenue-ratios greater than one percent. Thus, this is not considered to be a significant impact.

Although the final rule will not have a significant economic impact on a substantial number of small entities,
EPA nonetheless has tried to reduce the impact of this rule on small entities by allowing optional CEMS instead of requiring them, allowing information from tests conducted in recent years to show compliance rather than require all new testing and allowing reduced testing with continued compliance.

D. Unfunded Mandates Reform Act

This rule does not contain a Federal mandate that may result in expenditures of $100 million or more for state, local, and tribal governments, in the aggregate, or the private sector in any 1 year. Thus, this final rule is not subject to the requirements of sections 202 or 205 of

UMRA.

At proposal, EPA prepared under
section 202 of the UMRA a written
statement that is summarized in section VIII.D of the proposal preamble (75 FR 63260, October 14, 2010). A copy of the
UMRA written statement can be found
in the docket.

At proposal, the estimated costs were higher than the estimated costs of the final rule. At proposal, EPA prepared an RIA, including EPA’s assessment of costs and benefits, which is detailed in
the ‘‘Regulatory Impact Analysis:
Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Sewage Sludge Incineration Units ’’ in the docket. Based on estimated compliance
costs associated with the final rule and the predicted change in prices and production in the affected industries,
the estimated social costs of the final rule are $55 million ($).

At proposal, EPA consulted with governmental entities expected to be affected by the proposed rule, consistent with the intergovernmental consultation provisions of section 204 of the UMRA.
Those consultations are discussed in section VIII.D of the proposal preamble (75 FR 63260).

This final rule is not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. Because this final rule’s requirements apply equally to SSI units owned and/ or operated by governments or SSI units owned and/or operated by private entities, there would be no requirements that uniquely apply to such government or impose any disproportionate impacts
on them.

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government, as specified in
Executive Order 13132.

Under Executive Order 13132, EPA may not issue an action that has federalism implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by state and local governments, or EPA consults with state and local officials early in the process of developing the proposed

action.

EPA’s proposed action estimated expenditures of greater than $100 million to state and local governments and therefore as specified by the Executive Order, EPA consulted with elected state and local government officials, or their representative national organizations, when developing regulations and policies that impose substantial compliance costs on state and local governments. Pursuant to Agency policy, EPA conducted a briefing for the ‘‘ Big 10 ’’ intergovernmental organizations representing elected state and local government officials, as discussed in section VIII.D of the proposal preamble (75 FR 63260) to formally request their comments and input on the action. The Big 10 provided EPA with feedback on the proposed standards and EG for SSI

units.

EPA has concluded that this final rule will not have federalism implications, as defined by Agency guidance for implementing the Executive Order, due to the final rule’s direct compliance costs on state or local governments resulting in expenditures of less than $100 million.

In the spirit of Executive Order 13132 and consistent with EPA policy to promote communications between EPA and state and local governments, EPA specifically solicited comment on the proposed rule from state and local
officials. F. Executive Order 13175: Consultation
and Coordination With Indian Tribal

Governments

During proposal EPA was not aware of any SSI owned or operated by an Indian tribe or tribal governments, thus, Executive Order 13175 did not appear to have implications. However as specified in Executive Order 13175, (65 FR 67249, November 9, 2000), EPA has attempted to outreach and discuss possible SSI implications with tribal contacts.

EPA presented information on the SSI proposal and specifically solicited additional comment on the proposed
action from tribal contacts in the proposal period via the NTAA
conference calls.

EPA has received coordinated comments from the NTAA; those comments can be reviewed in the public docket, document number EPA–HQ–

OAR–2009–0559–0130.1. Commenters expressed that SSI units located in proximity to Indian country units, obtaining Title V permits, may trigger tribal consultation with regard to potential impact from the SSI unit. Commenters are dismayed, as they
believe EPA failed to consult with Indian tribes regarding the standards and have failed to fully assess the potential impacts of SSI units on tribal communities. Lastly, commenters recommended that EPA provide a map overlay that accounts for both SSI units and tribal lands so tribes can acquire a better understanding on how they might be affected by such sites and these standards in general.

EPA participated on two NTAA
conference calls to discuss the rule development process, first to provide general information on the development
of the SSI standards and second providing more specific background information on the purpose of the rulemaking, number and locations of units, and unit types. EPA allowed time for clarifying questions and requested information if any NTAA members were aware of any type of incinerator burning sewage sludge in Indian Country. EPA will provide a map overlay for the SSI docket so that tribes can acquire a better understanding on how they might be affected by SSI sites and the standards in general.

G. Executive Order 13045: Protection of
Children From Environmental Health and Safety Risks

EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying to those regulatory actions that concern health or safety risks, such that the analysis required under section
5–501 of the Executive Order has the


### 15403 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

potential to influence the regulation. This final action is not subject to
Executive Order 13045 because it is based solely on technology performance. We note however, that reductions in air emissions by these facilities will improve air quality, with expected positive impacts for children’s
health.

H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use

This action is not subject to Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not a significant regulatory action under Executive
Orders 12866 and 13563.

I. National Technology Transfer and
Advancement Act

Section 12(d) of the NTTAA of 1995, Public Law 104–113, 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards (VCS) in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary
consensus standards are technical standards ( e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable VCS.

EPA conducted searches for the

‘‘ Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Sewage Sludge Incineration Units ’’ through the
Enhanced National Standards Service Network Database managed by the
ANSI. We also contacted VCS organizations, accessed, and searched
their data bases.

This rulemaking involves technical
standards. EPA has decided to use ANSI/ASME PTC 19.10–1981, ‘‘ Flue and Exhaust Gas Analyses, ’’ for its manual methods of measuring the oxygen or
carbon dioxide content of the exhaust gas. These parts of ASME PTC 19.10– 1981 are acceptable alternatives to EPA Methods 6, 7. This standard is available from the ASME, Three Park Avenue, New York, NY 10016–5990.

Another VCS, ASTM D6784–02 (Reapproved 2008), ‘‘ Standard Test Method for Elemental, Oxidized, Particle-Bound and Total Mercury Gas Generated From Coal-Fired Stationary Sources (Ontario Hydro Method) ’’ is an acceptable alternative to Method 29 and
30B. EPA has also decided to use EPA Methods 5, 6, 6C, 7, 7E, 9, 10, 10A, 10B, 22, 23, 26A, 29 and 30B. No VCS were
found for EPA Method 9 and 22. During the search, if the title or abstract (if provided) of the VCS described technical sampling and analytical procedures that are similar to EPA’s reference method, EPA ordered a copy of the standard and reviewed it as a potential equivalent method. All potential standards were reviewed to determine the practicality of the VCS for this rule. This review requires significant method validation data that meet the requirements of EPA Method 301 for accepting alternative methods or scientific, engineering and policy equivalence to procedures in EPA reference methods. EPA may reconsider determinations of impracticality when
additional information is available for particular VCS.

The search identified other VCS that were potentially applicable for this rule
in lieu of EPA reference methods. After reviewing the available standards, EPA determined that candidate VCS (ASME B133.9–1994 (2001), ISO 9096:1992 (2003), ANSI/ASME PTC PTC–38–1980 (1985), ASTM D3685/D3685M–98 (2005), CAN/CSA Z223.1–M1977, ANSI/ASME PTC 19.10–1981, ISO 10396:1993 (2007), ISO 12039:2001, ASTM D5835–95 (2007), ASTM D6522– 00 (2005), CAN/CSA Z223.2–M86 (1999), ISO 7934:1998, ISO 11632:1998, ASTM D1608–98 (2003), ISO I1564:1998, CAN/CSA Z223.24–MI983, CAN/CSA Z223.21–MI978, ASTM D3162–94 (2005), EN 1948–3 (1996), EN 1911–1,2,3 (1998), ASTM D6735–01, EN 13211:2001, CAN/CSA Z223.26–MI987) identified for measuring emissions of pollutants or their surrogates subject to
emission standards in the rule would not be practical due to lack of equivalency, documentation, validation data, and other important technical and policy considerations.

Under 40 CFR 60.13(i) of the NSPS General Provisions, a source may apply to EPA for permission to use alternative test methods or alternative monitoring requirements in place of any required testing methods, performance specifications, or procedures in the final rule and any amendments.

J. Executive Order 12898: Federal
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

Executive Order 12898 (59 FR 7629, February 16, 1994) establishes Federal executive policy on environmental justice. Its main provision directs Federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs, policies and activities on minority populations and low-income populations in the United States.

EPA has determined that this final rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it
increases the level of environmental protection for all affected populations without having any disproportionately high and adverse human health or environmental effects on any population, including any minority or low-income populations. Additionally, the Agency has reviewed this final rule to determine if there was existing disproportionately high and adverse
human health or environmental effects on minority or low-income populations that could be mitigated by this rulemaking. An analysis of demographic data showed that the average of populations in close proximity to the sources, and thus most likely to be effected by the sources, were similar in demographic composition to national averages. The results of the demographic analysis are presented in

‘‘Review of Environmental Justice Impacts, ’’ June 2010, a copy of which is available in the SSI docket (EPA–HQ– OAR–2009–0559).

This final action establishes national emission standards for new and existing
SSI units. The EPA estimates that there are approximately 204 such units covered by this rule. The final rule will reduce emissions of many of the listed
HAP emitted from this source. This includes emissions of Cd, HCl, Pb, and Hg. Adverse health effects from these pollutants include cancer, irritation of the lungs, skin and mucus membranes, effects on the central nervous system and damage to the kidneys and acute
health disorders. The rule will also
result in substantial reductions of criteria pollutants such as CO, NO X , PM
and PM 2.5 and SO 2 . Sulfur dioxide and

NO X are precursors for the formation of

PM 2.5 and ozone. Reducing these
emissions will reduce ozone and PM 2.5 formation and associated health effects, such as adult premature mortality, chronic and acute bronchitis, asthma and other respiratory and cardiovascular diseases. For additional information, please refer to the RIA contained in the docket for this rulemaking. In EPA’s July 2010 ‘‘Interim Guidance on Considering Environmental Justice During the Development of an Action, ’’
EPA defines ‘‘ environmental justice ’’ as the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development,


### 15404 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

implementation, and enforcement of environmental laws, regulations, and policies.

To help achieve EPA’s goal for Environmental Justice ( i.e., the fair treatment and meaningful involvement of all people), EPA places particular emphasis on the public health of and environmental conditions affecting minority, low-income, and indigenous populations. In recognizing that these populations frequently bear a disproportionate burden of environmental harms and risks, EPA works to protect them from adverse public health and environmental effects of its programs. EPA looks at the vulnerabilities of these populations because they have historically been exposed to a combination of physical, chemical, biological, social, and cultural factors that have imposed greater
environmental burdens on them than those imposed on the general population.

To promote meaningful involvement, EPA has developed a communication and outreach strategy to ensure that
interested communities have access to this final rule, are aware of its content and have an opportunity to comment during the comment period. During the comment period, EPA publicized the rulemaking via environmental newsletters, tribal newsletters, environmental justice listservs, and the Internet, including the OPEI Rulemaking Gateway Web site ( http:// yosemite.epa.gov/opei/RuleGate.nsf/ ). EPA will also provide general rulemaking fact sheets ( e.g., why is this important for my community) for environmental justice community groups and conduct conference calls
with interested communities. In addition, state and Federal permitting requirements will provide state and local governments and members of affected communities the opportunity to provide comments on the permit conditions associated with permitting the sources affected by this rulemaking.

J. Congressional Review Act

The Congressional Review Act, 5

U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General
of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register.
This action is not a ‘‘major rule ’’ as defined by 5 U.S.C. 804(2). This rule will be effective May 20, 2011.

Introduction

**§ 60.4760 What does this subpart do?**

This subpart establishes new source performance standards for sewage sludge incineration (SSI) units. To the extent any requirement of this subpart is inconsistent with the requirements of subpart A of this part, the requirements of this subpart will apply.

**§ 60.4765 When does this subpart become**

**effective?**

This subpart takes effect on September 21, 2011. Some of the requirements in this subpart apply to planning a SSI unit and must be completed even before construction is initiated on a SSI unit ( i.e., the preconstruction requirements in §§ 60.4800 and 60.4805). Other requirements such as the emission limits, emission standards, and operating limits apply after the SSI unit begins operation.

Applicability and Delegation of Authority

**§ 60.4770 Does this subpart apply to my sewage sludge incineration unit?** 

Yes, your SSI unit is an affected
source if it meets all the criteria specified in paragraphs (a) through (c) of
this section.

(a) Your SSI unit is a SSI unit for
which construction commenced after October 14, 2010 or for which
modification commenced after September 21, 2011.

(b) Your SSI unit is a SSI unit as defined in § 60.4930.

(c) Your SSI unit is not exempt under § 60.4780.

**§ 60.4775 What is a new sewage sludge**

**incineration unit?**

(a) A new SSI unit is a SSI unit that meets either of the two criteria specified in paragraph (a)(1) or (a)(2) of this

section.

(1) Commenced construction after October 14, 2010.

(2) Commenced modification after September 21, 2011.

(b) Physical or operational changes made to your SSI unit to comply with the emission guidelines in subpart MMMM of this part (Emission Guidelines and Compliance Times for Existing Sewage Sludge Incineration Units) do not qualify as a modification under this subpart.

**§ 60.4780 What sewage sludge incineration units are exempt from this**  **subpart?**

This subpart exempts combustion units that incinerate sewage sludge and
are not located at a wastewater treatment facility designed to treat domestic sewage sludge. These units may be subject to another subpart of this part ( e.g., subpart CCCC of this part). The owner or operator of such a combustion unit must notify the Administrator of an exemption claim
under this section.

**§ 60.4785 Who implements and enforces this subpart?** 

(a) This subpart can be implemented and enforced by the Administrator, as defined in § 60.2, or a delegated authority such as your state, local, or tribal agency. If the Administrator has delegated authority to your state, local, or tribal agency, then that agency (as well as the Administrator) has the authority to implement and enforce this subpart. You should contact your EPA Regional Office to find out if this subpart is delegated to your state, local, or tribal agency.

(b) In delegating implementation and enforcement authority of this subpart to a state, local, or tribal agency, the authorities contained in paragraph (c) of this section are retained by the
Administrator and are not transferred to the state, local, or tribal agency.

(c) The authorities that will not be delegated to state, local, or tribal agencies are specified in paragraphs (c)(1) through (c)(8) of this section.

(1) Approval of alternatives to the
emission limits and standards in Tables 1 and 2 to this subpart and operating limits established under § 60.4850.

(2) Approval of major alternatives to
test methods.

(3) Approval of major alternatives to monitoring.

(4) Approval of major alternatives to recordkeeping and reporting.

(5) The requirements in § 60.4855. (6) The requirements in § 60.4835(b)(2).

(7) Performance test and data reduction waivers under § 60.8(b).

(8) Preconstruction siting analysis in § 60.4800 and § 60.4805.

**§ 60.4790 How are these new source performance standards structured?** 

These new source performance standards contain the nine major


### 15406 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

components listed in paragraphs (a) through (i) of this section.

(a) Preconstruction siting analysis. (b) Operator training and qualification.

(c) Emission limits, emission standards, and operating limits.

(d) Initial compliance requirements. (e) Continuous compliance requirements.

(f) Performance testing, monitoring, and calibration requirements.

(g) Recordkeeping and reporting. (h) Definitions. (i) Tables.

**§ 60.4795 Do all nine components of these new source performance standards apply at** 

**the same time?**

No. You must meet the preconstruction siting analysis requirements before you commence
construction of the SSI unit. The operator training and qualification, emission limits, emission standards, operating limits, performance testing, and compliance, monitoring, and most recordkeeping and reporting requirements are met after the SSI unit begins operation.

Preconstruction Siting Analysis

**§ 60.4800 Who must prepare a siting analysis?** 

(a) You must prepare a siting analysis if you plan to commence construction of a SSI unit after October 14, 2010.

(b) You must prepare a siting analysis if you are required to submit an initial application for a construction permit under 40 CFR part 51, subpart I, or 40 CFR part 52, as applicable, for the modification of your SSI unit.

**§ 60.4805 What is a siting analysis?**

(a) The siting analysis must consider air pollution control alternatives that minimize, on a site-specific basis, to the maximum extent practicable, potential risks to public health or the environment, including impacts of the affected SSI unit on ambient air quality, visibility, soils, and vegetation. In considering such alternatives, the analysis may consider costs, energy impacts, nonair environmental impacts, or any other factors related to the practicability of the alternatives.

(b) Analyses of your SSI unit’s impacts that are prepared to comply with state, local, or other Federal regulatory requirements may be used to satisfy the requirements of this section, provided they include the consideration of air pollution control alternatives specified in paragraph (a) of this

section.

(c) You must complete and submit the siting requirements of this section as required under § 60.4915(a)(3) prior to commencing construction.

Operator Training and Qualification

**§ 60.4810 What are the operator training and qualification requirements?** 

(a) A SSI unit cannot be operated unless a fully trained and qualified SSI unit operator is accessible, either at the facility or can be at the facility within 1 hour. The trained and qualified SSI unit operator may operate the SSI unit directly or be the direct supervisor of one or more other plant personnel who operate the unit. If all qualified SSI unit operators are temporarily not accessible, you must follow the procedures in § 60.4835.

(b) Operator training and qualificationmust be obtained through a stateapproved program or by completing the requirements included in paragraph (c)
of this section.

(c) Training must be obtained by completing an incinerator operator training course that includes, at a minimum, the three elements described in paragraphs (c)(1) through (c)(3) of this

section.

(1) Training on the 10 subjects listed in paragraphs (c)(1)(i) through (c)(1)(x)
of this section.

(i) Environmental concerns, including types of emissions.

(ii) Basic combustion principles, including products of combustion.

(iii) Operation of the specific type of incinerator to be used by the operator, including proper startup, sewage sludge feeding, and shutdown procedures.

(iv) Combustion controls and monitoring.

(v) Operation of air pollution control equipment and factors affecting performance (if applicable).

(vi) Inspection and maintenance of the incinerator and air pollution control
devices.

(vii) Actions to prevent malfunctions or to prevent conditions that may lead
to malfunctions.

**defense for exceedance of an emission limit or standard during malfunction?** 

In response to an action to enforce the
numerical emission standards set forth in paragraph § 60.4845, you may assert
an affirmative defense to a claim for civil penalties for exceedances of emission limits that are caused by malfunction, as defined in § 60.2. Appropriate penalties may be assessed, however, if you fail to meet your burden of proving all of the requirements in the
affirmative defense. The affirmative
defense shall not be available for claims for injunctive relief.

(a) To establish the affirmative defense in any action to enforce such a limit, you must timely meet the notification requirements in paragraph (b) of this section, and must prove by a preponderance of evidence that the conditions in paragraphs (a)(1) through (a)(9) of this section are met.

(1) The excess emissions meet: (i) Were caused by a sudden, infrequent, and unavoidable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a normal or usual manner, and

(ii) Could not have been prevented through careful planning, proper design or better operation and maintenance practices, and

(iii) Did not stem from any activity or
event that could have been foreseen and avoided, or planned for, and

(iv) Were not part of a recurring pattern indicative of inadequate design, operation, or maintenance, and (2) Repairs were made as expeditiously as possible when the applicable emission limits were being exceeded. Off-shift and overtime labor were used, to the extent practicable to make these repairs,
and

(3) The frequency, amount and
duration of the excess emissions (including any bypass) were minimized to the maximum extent practicable during periods of such emissions, and

(4) If the excess emissions resulted from a bypass of control equipment or a process, then the bypass was unavoidable to prevent loss of life, personal injury, or severe property damage, and

(5) All possible steps were taken to minimize the impact of the excess emissions on ambient air quality, the environment and human health, and

(6) All emissions monitoring and control systems were kept in operation if at all possible consistent with safety and good air pollution control practices,
and

(7) All of the actions in response to
the excess emissions were documented by properly signed, contemporaneous operating logs, and

(8) At all times, the affected facility was operated in a manner consistent with good practices for minimizing emissions, and

(9) A written root cause analysis has been prepared the purpose of which is to determine, correct, and eliminate the primary causes of the malfunction and the excess emissions resulting from the malfunction event at issue. The analysis shall also specify, using best monitoring methods and engineering judgment, the
amount of excess emissions that were
the result of the malfunction.

(b) The owner or operator of the SSI unit experiencing an exceedance of its emission limit(s) during a malfunction, shall notify the Administrator by telephone or facsimile (fax) transmission as soon as possible, but no later than 2 business days after the initial occurrence of the malfunction, if
it wishes to avail itself of an affirmative defense to civil penalties for that malfunction. The owner or operator seeking to assert an affirmative defense shall also submit a written report to the Administrator within 45 days of the
initial occurrence of the exceedance of the standard in § 60.4845 to demonstrate, with all necessary supporting documentation, that it has met the requirements set forth in paragraph (a) of this section. The owner or operator may seek an extension of this deadline for up to 30 additional days by submitting a written request to the Administrator before the expiration of the 45 day period. Until a request for an extension has been approved by the Administrator, the owner or operator is subject to the requirement to submit such report within 45 days of the initial
occurrence of the exceedance.

(1) Measure the concentration of each dioxin/furan tetra- through octachlorinated-isomer emitted using Method 23 at 40 CFR part 60, appendix

A–7.

(2) Multiply the concentration of eachdioxin/furan (tetra- through octachlorinated) isomer by its corresponding toxic equivalency factor specified in Table 4 to this subpart.

(3) Sum the products calculated in accordance with paragraph (c)(2) of this
section to obtain the total concentration
of dioxins/furans emitted in terms of toxic equivalency.

(d) Submit an initial compliance report, as specified in § 60.4915(c).

(e) If you demonstrate initial compliance using the performance test specified in paragraph (a) of this section, then the provisions of this paragraph (e) apply. If a force majeure is about to occur, occurs, or has occurred for which you intend to assert a claim of force majeure, you must notify the Administrator in writing as specified in § 60.4915(g). You must conduct the initial performance test as soon as practicable after the force majeure occurs. The Administrator will determine whether or not to grant the extension to the initial performance test deadline, and will notify you in writing of approval or disapproval of the request for an extension as soon as practicable. Until an extension of the performance test deadline has been approved by the Administrator, you remain strictly subject to the requirements of this subpart.

Continuous Compliance Requirements

**§ 60.4885 How and when do I demonstrate continuous compliance with the emission** 

**limits and standards?**

To demonstrate continuous compliance with the emission limits and standards specified in Table 1 or 2 to this subpart, use the procedures specified in paragraph (a) of this section for particulate matter, hydrogen chloride, dioxins/furans (total mass basis or toxic equivalency basis), mercury, nitrogen oxides, sulfur dioxide, cadmium, lead, and fugitive emissions from ash handling, and follow the procedures specified in paragraph (b) of this section for carbon monoxide. In lieu of using the procedures specified in paragraph (a) of this section, you also have the option to demonstrate continuous compliance using the procedures specified in paragraph (b) of this section for particulate matter, hydrogen chloride, dioxins/furans (total mass basis or toxic equivalency basis), mercury, nitrogen oxides, sulfur dioxide, cadmium, and lead. You must meet the requirements of paragraphs (a) and (b) of this section, as applicable, and paragraphs (c) through (e) of this section, according to the performance testing, monitoring, and calibration requirements in § 60.4900(a) and (b). You may also petition the Administrator for alternative monitoring parameters as specified in paragraph (f)
of this section.

(a) Demonstrate continuous compliance using a performance test. Except as provided in paragraphs (a)(3) and (e) of this section, following the date that the initial performance test for each pollutant in Table 1 or 2 to this subpart except carbon monoxide is completed, you must conduct a performance test for each such pollutant on an annual basis (between 11 and 13 calendar months following the previous performance test). The performance test must be conducted using the test methods, averaging methods, and minimum sampling volumes or durations specified in Table 1 or 2 to this subpart and according to the testing, monitoring, and calibration requirements specified in § 60.4900(a).

(1) You may conduct a repeat performance test at any time to establish new values for the operating limits to apply from that point forward. The Administrator may request a repeat performance test at any time.

(2) You must repeat the performance test within 60 days of a process change, as defined in § 60.4930.

(3) Except as specified in paragraphs (a)(1) and (2) of this section, you can conduct performance tests less often for a given pollutant, as specified in paragraphs (a)(3)(i) through (iii) of this

section.

(i) You can conduct performance tests less often if your performance tests for the pollutant for at least 2 consecutive years show that your emissions are at or below 75 percent of the emission limit specified in Table 2 or 3 to this subpart, and there are no changes in the operation of the affected source or air pollution control equipment that could increase emissions. In this case, you do not have to conduct a performance test for that pollutant for the next 2 years. You must conduct a performance test during the third year and no more than 37 months after the previous performance test.

(ii) If your SSI unit continues to meet the emission limit for the pollutant, you may choose to conduct performance tests for the pollutant every third year if your emissions are at or below 75 percent of the emission limit, and if there are no changes in the operation of the affected source or air pollution control equipment that could increase emissions, but each such performance test must be conducted no more than 37 months after the previous performance

test.

(iii) If a performance test shows emissions exceeded 75 percent of the emission limit for a pollutant, you must conduct annual performance tests for that pollutant until all performance tests over 2 consecutive years show compliance.

(b) Demonstrate continuous compliance using a continuous emissions monitoring system or continuous automated sampling system. The option to use a continuous emissions monitoring system for hydrogen chloride, dioxins/furans, cadmium, or lead takes effect on the date a final performance specification applicable to hydrogen chloride, dioxins/furans, cadmium, or lead is published in the Federal Register . The option to use a continuous automated sampling system for dioxins/furans
takes effect on the date a final performance specification for such a continuous automated sampling system is published in the Federal Register

. Collect data as specified in § 60.4900(b)(6) and use the following procedures:

(1) To demonstrate continuous compliance with the carbon monoxide emission limit, you must use the carbon
monoxide continuous emissions monitoring system specified in § 60.4900(b). For determining compliance with the carbon monoxide concentration limit using carbon monoxide CEMS, the correction to 7 percent oxygen does not apply during periods of startup or shutdown. Use the
measured carbon monoxide concentration without correcting for oxygen concentration in averaging with
other carbon monoxide concentrations (corrected to 7 percent oxygen) to determine the 24-hour average value.

(2) To demonstrate continuous compliance with the emission limits for particulate matter, hydrogen chloride, dioxins/furans (total mass basis or toxic equivalency basis), mercury, nitrogen oxides, sulfur dioxide, cadmium, and lead, you may substitute the use of a continuous monitoring system in lieu of conducting the annual performance test required in paragraph (a) of this section,
as follows:

(i) You may substitute the use of a continuous emissions monitoring system for any pollutant specified in paragraph (b)(2) of this section in lieu of conducting the annual performance test for that pollutant in paragraph (a) of this

section.

(ii) You may substitute the use of a continuous automated sampling system for mercury or dioxins/furans in lieu of

conducting the annual mercury or dioxin/furan performance test in paragraph (a) of this section.

(3) If you use a continuous emissions monitoring system to demonstrate compliance with an applicable emission limit in either paragraph (b)(1) or (b)(2) of this section, you must use the continuous emissions monitoring system and follow the requirements specified in § 60.4900(b). You must measure emissions according to § 60.13 to calculate 1-hour arithmetic averages, corrected to 7 percent oxygen (or carbon dioxide). You must demonstrate initial compliance using a 24-hour block average of these 1-hour arithmetic average emission concentrations, calculated using Equation 19–19 in
section 12.4.1 of Method 19 of 40 CFR part 60, appendix A–7.

(4) If you use a continuous automated sampling system to demonstrate compliance with an applicable emission limit in paragraph (b)(2) of this section,
you must:

(i) Use the continuous automated sampling system specified in § 60.58b(p) and (q), and measure and calculate average emissions corrected to 7 percent oxygen (or carbon dioxide) according to § 60.58b(p) and your monitoring plan.

(A) Use the procedures specified in § 60.58b(p) to calculate 24-hour averages to determine compliance with the mercury emission limit in Table 1 or 2 to this subpart.

(5) Except as provided in paragraph (e) of this section, you must complete your periodic performance evaluations required under your monitoring plan for any continuous emissions monitoring system and continuous automated sampling systems, according to the schedule specified in your monitoring plan. If you were previously determining compliance by conducting an annual performance test (or according to the less frequent testing for a pollutant as provided in paragraph (a)(3) of this section), you must complete the initial performance evaluation required in your monitoring plan in § 60.4880 for the continuous monitoring system prior to using the continuous emissions monitoring system to demonstrate compliance or continuous automated sampling system. Your performance evaluation must be conducted using the procedures and acceptance criteria specified in § 60.4880(a)(3).

(c) To demonstrate compliance with the dioxins/furans toxic equivalency emission limit in paragraph (a) or (b) of this section, you must determine dioxins/furans toxic equivalency as

follows:

(1) Measure the concentration of eachdioxin/furan tetra- through octachlorinated isomer emitted using EPA

Method 23.

(2) For each dioxin/furan (tetrathrough octa-chlorinated) isomer measured in accordance with paragraph (c)(1) of this section, multiply the isomer concentration by its corresponding toxic equivalency factor specified in Table 4 to this subpart.

(3) Sum the products calculated in accordance with paragraph (c)(2) of this

section to obtain the total concentration

of dioxins/furans emitted in terms of toxic equivalency.

(d) You must submit the annual compliance report specified in § 60.4915(d). You must submit the deviation report specified in § 60.4915(e) for each instance that you

did not meet each emission limit in Table 1 or 2 to this subpart.

If a force majeure is about to occur, occurs, or has occurred for which you intend to assert a claim of force majeure, you must notify the Administrator in writing as specified in § 60.4915(g). You must conduct the performance test as soon as practicable after the force majeure

occurs. The Administrator will determine whether or not to grant the extension to the performance test deadline, and will notify you in writing of approval or disapproval of the request for an extension as soon as practicable. Until an extension of the performance test deadline has been approved by the Administrator, you remain strictly subject to the requirements of this subpart.

(f) After any initial requests in § 60.4880 for alternative monitoring requirements for initial compliance, you may subsequently petition the Administrator for alternative monitoring parameters as specified in §§ 60.13(i) and 60.4880(e). **§ 60.4890 How do I demonstrate continuous compliance with my operating**

(B) If corrective action is required,
each alarm time shall be counted as a
minimum of 1 hour.

(C) If you take longer than 1 hour to initiate corrective action, each alarm time ( i.e., time that the alarm sounds) is
counted as the actual amount of time taken by you to initiate corrective

action.

(ii) Your maximum alarm time is equal to 5 percent of the operating time during a 6-month period, as specified in § 60.4850(c).

(b) Operation above the established maximum, below the established minimum, or outside the allowable range of the operating limits specified in paragraph (a) of this section constitutes a deviation from your operating limits established under this subpart, except during performance tests conducted to determine compliance with the emission and operating limits or to establish new operating limits.

Introduction

**60.5000 What is the purpose of this subpart?** 

This subpart establishes emission guidelines and compliance schedules for the control of emissions from sewage sludge incineration (SSI) units. The pollutants addressed by these emission guidelines are listed in Tables 2 and 3 to this subpart. These emission guidelines are developed in accordance with sections 111(d) and 129 of the Clean Air Act and subpart B of this part. To the extent any requirement of this subpart is inconsistent with the requirements of subpart A of this part, the requirements of this subpart will apply.

**§ 60.5005 Am I affected by this subpart?**

(a) If you are the Administrator of an air quality program in a state or United States protectorate with one or more SSI
units that commenced construction on or before October 14, 2010, you must submit a state plan to U.S. Environmental Protection Agency (EPA) that implements the emission guidelines contained in this subpart.

(b) You must submit the state plan to EPA by March 21, 2012.


### 15430 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

**§ 60.5010 Is a state plan required for all**

**states?**

No. You are not required to submit a state plan if there are no SSI units for
which construction commenced on or before October 14, 2010 in your state, and you submit a negative declaration letter in place of the state plan.

**§ 60.5015 What must I include in my state plan?** 

(a) You must include the nine items described in paragraphs (a)(1) through (a)(9) of this section in your state plan.

(1) Inventory of affected SSI units, including those that have ceased operation but have not been dismantled.

(2) Inventory of emissions from affected SSI units in your state.

(3) Compliance schedules for each
affected SSI unit.

(4) Emission limits, emission standards, operator training and qualification requirements, and operating limits for affected SSI units that are at least as protective as the emission guidelines contained in this subpart.

(5) Performance testing, recordkeeping, and reporting requirements.

(6) Certification that the hearing on the state plan was held, a list of witnesses and their organizational affiliations, if any, appearing at the hearing, and a brief written summary of each presentation or written
submission.

(7) Provision for state progress reports

to EPA.

(8) Identification of enforceable state mechanisms that you selected for implementing the emission guidelines of this subpart.

(9) Demonstration of your state’s legal authority to carry out the sections 111(d) and 129 state plan.

(b) Your state plan may deviate from
the format and content of the emission guidelines contained in this subpart. However, if your state plan does deviate in content, you must demonstrate that your state plan is at least as protective as the emission guidelines contained in this subpart. Your state plan must address regulatory applicability, increments of progress for retrofit, operator training and qualification, emission limits and standards, performance testing, operating limits, monitoring, and recordkeeping and reporting.

(c) You must follow the requirements of subpart B of this part (Adoption and Submittal of state plans for Designated Facilities) in your state plan. **§ 60.5020 Is there an approval process for my state plan?** 

Yes. The EPA will review your state plan according to § 60.27.

**§ 60.5025 What if my state plan is not approvable?** 

If you do not submit an approvable state plan (or a negative declaration letter) by March 21, 2013, EPA will develop a Federal plan according to § 60.27 to implement the emission guidelines contained in this subpart. Owners and operators of SSI units not covered by an approved state plan must comply with the Federal plan. The Federal plan is an interim action and will be automatically withdrawn when your state plan is approved.

**§ 60.5030 Is there an approval process for a negative declaration letter?** 

No. The EPA has no formal review process for negative declaration letters. Once your negative declaration letter has been received, EPA will place a copy in the public docket and publish
a notice in the Federal Register . If, at a later date, a SSI unit for which
construction commenced on or before October 14, 2010 is found in your state, the Federal plan implementing the emission guidelines contained in this subpart would automatically apply to that SSI unit until your state plan is approved.

**§ 60.5035 What compliance schedule must I include in my state plan?** 

(a) For SSI units that commenced construction on or before October 14, 2010, your state plan must include compliance schedules that require SSI units to achieve final compliance as expeditiously as practicable after approval of the state plan but not later
than the earlier of the two dates specified in paragraphs (a)(1) and (a)(2)
of this section.

(1) March 21, 2016. (2) Three years after the effective date of state plan approval.

(b) For compliance schedules that extend more than 1 year following the effective date of state plan approval, state plans must include dates for enforceable increments of progress as specified in § 60.5090.

**§ 60.5040 Are there any state plan requirements for this subpart that apply**  **instead of the requirements specified in subpart B?** 

Yes. Subpart B establishes general requirements for developing and processing section 111(d) state plans. This subpart applies instead of the requirements in subpart B of this part, as specified in paragraphs (a) and (b) of
this section: (a) State plans developed to implement this subpart must be as protective as the emission guidelines contained in this subpart. State plans must require all SSI units to comply by the dates specified in § 60.5035. Thisapplies instead of the option for case-bycase less stringent emission standards and longer compliance schedules in § 60.24(f).

(b) State plans developed to implement this subpart are required to include two increments of progress for
the affected SSI units. These two
minimum increments are the final control plan submittal date and final compliance date in § 60.21(h)(1) and (5). This applies instead of the requirement of § 60.24(e)(1) that would require a state plan to include all five increments of progress for all SSI units.

**§ 60.5045 In lieu of a state plan submittal, are there other acceptable option(s) for a**  **state to meet its section 111(d)/129 (b)(2) obligations?** 

Yes, a state may meet its Clean Air Act section 111(d)/129 obligations by submitting an acceptable written request for delegation of the Federal plan that meets the requirements of this section. This is the only other option for a state to meet its section 111(d)/129 obligations.

(a) An acceptable Federal plan delegation request must include the following:

(1) A demonstration of adequate resources and legal authority to administer and enforce the Federal plan.

(2) The items under § 60.5015(a)(1), (a)(2), and (a)(7).

(3) Certification that the hearing on the state delegation request, similar to the hearing for a state plan submittal, was held, a list of witnesses and their organizational affiliations, if any, appearing at the hearing, and a brief written summary of each presentation or
written submission.

(4) A commitment to enter into a Memorandum of Agreement with the Regional Administrator that sets forth the terms, conditions, and effective date of the delegation and that serves as the mechanism for the transfer of authority. Additional guidance and information is given in EPA’s Delegation Manual, Item 7–139, Implementation and Enforcement of 111(d)(2) and 111(d)/(2)/ 129 (b)(3) Federal plans.

(b) A state with an already approved SSI Clean Air Act section 111(d)/129 state plan is not precluded from receiving EPA approval of a delegation request for the revised Federal plan, provided the requirements of paragraph (a) of this section are met, and at the time of the delegation request, the state


### 15431 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

also requests withdrawal of EPA’s previous state plan approval.

(c) A state’s Clean Air Act section 111(d)/129 obligations are separate from its obligations under title V of the Clean

Air Act.

**§ 60.5050 What authorities will not be delegated to state, local, or tribal agencies?** 

The authorities that will not be delegated to state, local, or tribal agencies are specified in paragraphs (a) through (g) of this section.

(a) Approval of alternatives to the
emission limits and standards in Tables 2 and 3 to this subpart and operating limits established under § 60.5175 or § 60.5190.

(b) Approval of major alternatives to
test methods.

(c) Approval of major alternatives to monitoring.

(d) Approval of major alternatives to recordkeeping and reporting.

(e) The requirements in § 60.5175. (f) The requirements in § 60.5155(b)(2).

(g) Performance test and data reduction waivers under § 60.8(b).

**§ 60.5055 Does this subpart directly affect SSI unit owners and operators in my state?** 

(a) No. This subpart does not directly affect SSI unit owners and operators in your state. However, SSI unit owners and operators must comply with the state plan you develop to implement the emission guidelines contained in this subpart. States may choose to incorporate the model rule text directly in their state plan.

(b) If you do not submit an approvable plan to implement and enforce the guidelines contained in this subpart by March 21, 2012, EPA will implement and enforce a Federal plan, as provided in § 60.5025, to ensure that each unit within your state that commenced construction on or before October 14, 2010 reaches compliance with all the provisions of this subpart by the dates specified in § 60.5035.

Applicability of State Plans

**§ 60.5060 What SSI units must I address in my state plan?** 

(a) Your state plan must address SSI
units that meet all three criteria described in paragraphs (a)(1) through (3) of this section.

(1) SSI units in your state that
commenced construction on or before October 14, 2010.

(2) SSI units that meet the definition of a SSI unit as defined in § 60.5250.

(3) SSI units not exempt under § 60.5065.

(b) If the owner or operator of a SSI unit makes changes that meet the definition of modification after September 21, 2011, the SSI unit becomes subject to subpart LLLL of this part and the state plan no longer applies
to that unit.

(c) If the owner or operator of a SSI unit makes physical or operational changes to a SSI unit for which
construction commenced on or before September 21, 2011 primarily to comply with your state plan, subpart LLLL of this part does not apply to that unit. Such changes do not qualify as modifications under subpart LLLL of this part.

**§ 60.5065 What SSI units are exempt from my state plan?** 

This subpart exempts combustion units that incinerate sewage sludge and
are not located at a wastewater treatment facility designed to treat domestic sewage sludge. These units may be subject to another subpart of this part ( e.g., subpart CCCC of this part). The owner or operator of such a combustion unit must notify the Administrator of an exemption claim
under this section.

Use of Model Rule

**§ 60.5070 What is the** ‘‘ **model rule** ’’ **in this subpart?** 

(a) The model rule is the portion of these emission guidelines (§§ 60.5085 through 60.5250) that addresses the regulatory requirements applicable to SSI units. The model rule provides these requirements in regulation format. You must develop a state plan that is at least as protective as the model rule. You may use the model rule language as part of your state plan. Alternative language may be used in your state plan if you demonstrate that the alternative language is at least as protective as the model rule contained in this subpart.

(b) In the model rule of §§ 60.5085 through 60.5250, ‘‘you ’’ and

‘‘Administrator’’ have the meaning specified in § 60.5250.

**§ 60.5075 How does the model rule relate to the required elements of my state plan?** 

Use the model rule to satisfy the state plan requirements specified in § 60.5015(a)(3) through (a)(5).

**§ 60.5080 What are the principal components of the model rule?** 

The model rule contains the nine major components listed in paragraphs (a) through (i) of this section.

(a) Increments of progress toward compliance.

(b) Operator training and qualification.

(c) Emission limits, emission standards, and operating limits. (d) Initial compliance requirements. (e) Continuous compliance requirements.

(f) Performance testing, monitoring, and calibration requirements.

(g) Recordkeeping and reporting. (h) Definitions. (i) Tables.

Model Rule—Increments of Progress

**§ 60.5085 What are my requirements for meeting increments of progress and**  **achieving final compliance?**

If you plan to achieve compliance more than 1 year following the effective date of state plan approval, you must meet the two increments of progress specified in paragraphs (a) and (b) of
this section.

(a) Submit a final control plan. (b) Achieve final compliance.

**§ 60.5090 When must I complete each increment of progress?** 

Table 1 to this subpart specifies compliance dates for each increment of

progress.

**§ 60.5095 What must I include in the**

**notifications of achievement of increments of progress?** 

Your notification of achievement of increments of progress must include the three items specified in paragraphs (a) through (c) of this section.

(a) Notification that the increment of progress has been achieved.

(b) Any items required to be
submitted with each increment of

progress.

(c) Signature of the owner or operator
of the SSI unit.

**§ 60.5100 When must I submit the**

**notifications of achievement of increments of progress?** 

Notifications for achieving increments of progress must be postmarked no later than 10 business days after the compliance date for the increment.

**§ 60.5105 What if I do not meet an increment of progress?** 

If you fail to meet an increment of progress, you must submit a notification to the Administrator postmarked within 10 business days after the date for that increment of progress in Table 1 to this subpart. You must inform the Administrator that you did not meet the increment, and you must continue to submit reports each subsequent
calendar month until the increment of progress is met.

**§ 60.5110 How do I comply with the increment of progress for submittal of a**  **control plan?**

For your control plan increment of progress, you must satisfy the two

**§ 60.5120 What must I do if I close my SSI**

**unit and then restart it?**

(a) If you close your SSI unit but will restart it prior to the final compliance date in your state plan, you must meet the increments of progress specified in § 60.5085.

(b) If you close your SSI unit but will restart it after your final compliance date, you must complete emission
control retrofits and meet the emission limits, emission standards, and operating limits on the date your unit restarts operation.

**§ 60.5125 What must I do if I plan to permanently close my SSI unit and not** 

**restart it?**

If you plan to close your SSI unit rather than comply with the state plan, submit a closure notification, including the date of closure, to the Administrator by the date your final control plan is
due.

Model Rule—Operator Training and Qualification

**§ 60.5130 What are the operator training and qualification requirements?** 

(a) A SSI unit cannot be operated unless a fully trained and qualified SSI unit operator is accessible, either at the facility or can be at the facility within 1 hour. The trained and qualified SSI unit operator may operate the SSI unit directly or be the direct supervisor of one or more other plant personnel who operate the unit. If all qualified SSI unit operators are temporarily not accessible, you must follow the procedures in § 60.5155.

(iii) A discussion of how you will establish the upper and/or lower values for these parameters that will establish the operating limits on these parameters, including a discussion of the averaging periods associated with those parameters for determining compliance.

(iv) 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.

(v) A discussion identifying the frequency and methods for recalibrating the instruments you will use for monitoring these parameters.

**§ 60.5180 Do the emission limits, emission standards, and operating limits apply**  **during periods of startup, shutdown, and**

**malfunction?**

The emission limits and standards apply at all times and during periods of malfunction. The operating limits apply at all times that sewage sludge is in the combustion chamber ( i.e., until the sewage sludge feed to the combustor has been cut off for a period of time not less than the sewage sludge incineration residence time). For determining compliance with the CO concentration limit using CO CEMS, the correction to 7 percent oxygen does not apply during periods of startup or shutdown. Use the
measured CO concentration without correcting for oxygen concentration in averaging with other CO concentrations (corrected to 7 percent O 2 ) to determine the 24-hour average value.

**§ 60.5181 How do I establish an affirmative**

**defense for exceedance of an emission limit or standard during malfunction?** 

In response to an action to enforce the
numerical emission standards set forth in paragraph § 60.5165, you may assert
an affirmative defense to a claim for civil penalties for exceedances of emission limits that are caused by malfunction, as defined in § 60.2. Appropriate penalties may be assessed however, if you fail to meet your burden of proving all of the requirements in the
affirmative defense. The affirmative
defense shall not be available for claims for injunctive relief.

(a) To establish the affirmative defense in any action to enforce such a limit, you must timely meet the notification requirements in paragraph (b) of this section, and must prove by a preponderance of evidence that the conditions in paragraphs (a)(1) through (a)(9) of this section are met.

(1) The excess emissions: (i) Were caused by a sudden, infrequent, and unavoidable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a normal or usual manner, and (ii) Could not have been prevented through careful planning, proper design or better operation and maintenance practices, and (iii) Did not stem from any activity or event that could have been foreseen and avoided, or planned for, and

(iv) Were not part of a recurring pattern indicative of inadequate design, operation, or maintenance, and

(2) Repairs were made as expeditiously as possible when the applicable emission limits were being
exceeded. Off-shift and overtime labor were used, to the extent practicable to make these repairs, and (3) The frequency, amount and duration of the excess emissions (including any bypass)
were minimized to the maximum extent practicable during periods of such emissions, and (4) If the excess emissions resulted from a bypass of control equipment or a process, then the bypass was unavoidable to prevent loss of life, personal injury, or severe property damage, and

(5) All possible steps were taken to minimize the impact of the excess emissions on ambient air quality, the environment and human health, and

(6) All emissions monitoring and control systems were kept in operation if at all possible consistent with safety and good air pollution control practices,
and

(7) All of the actions in response to
the excess emissions were documented by properly signed, contemporaneous operating logs, and

(8) At all times, the affected facility was operated in a manner consistent with good practices for minimizing emissions, and

(9) A written root cause analysis has been prepared the purpose of which is to determine, correct, and eliminate the primary causes of the malfunction and the excess emissions resulting from the malfunction event at issue. The analysis shall also specify, using best monitoring methods and engineering judgment, the
amount of excess emissions that were
the result of the malfunction.

(b) The owner or operator of the SSI unit experiencing an exceedance of its emission limit(s) during a malfunction, shall notify the Administrator by telephone or facsimile (fax) transmission as soon as possible, but no later than 2 business days after the initial occurrence of the malfunction, if
it wishes to avail itself of an affirmative defense to civil penalties for that malfunction. The owner or operator seeking to assert an affirmative defense shall also submit a written report to the Administrator within 45 days of the
initial occurrence of the exceedance of the standard in § 60.5165 to demonstrate, with all necessary supporting documentation, that it has met the requirements set forth in paragraph (a) of this section. The owner or operator may seek an extension of this deadline for up to 30 additional days by submitting a written request to the Administrator before the expiration of the 45 day period. Until a request for an extension has been approved by the Administrator, the owner or operator is subject to the requirement to submit such report within 45 days of the initial
occurrence of the exceedance.

Model Rule—Continuous Compliance Requirements

**§ 60.5205 How and when do I demonstrate continuous compliance with the emission** 

**limits and standards?**

To demonstrate continuous compliance with the emission limits and standards specified in Table 2 or 3 to this subpart, use the procedures specified in paragraph (a) of this section. In lieu of using the procedures specified in paragraph (a) of this section, you have the option to demonstrate initial compliance using the procedures specified in paragraph (b) of this section for particulate matter, hydrogen chloride, carbon monoxide, dioxins/furans (total mass basis or toxic equivalency basis), mercury, nitrogen oxides, sulfur dioxide, cadmium, lead, and fugitive emissions from ash handling. You must meet the requirements of paragraphs (a) and (b) of this section, as applicable, and paragraphs (c) through (e) of this section, according to the performance testing, monitoring, and calibration requirements in § 60.5220(a) and (b). You may also petition the Administrator for alternative monitoring parameters as specified in paragraph (f) of this section.

(a) Demonstrate continuous compliance using a performance test. Except as provided in paragraphs (a)(3) and (e) of this section, following the date that the initial performance test for each pollutant in Table 2 or 3 to this subpart is completed, you must conduct a performance test for each such pollutant on an annual basis (between 11 and 13 calendar months following the previous performance test). The performance test must be conducted using the test methods, averaging methods, and minimum sampling volumes or durations specified in Table 2 or 3 to this subpart and according to the testing, monitoring, and calibration requirements specified in § 60.5220(a).

(1) You may conduct a repeat performance test at any time to establish new values for the operating limits to apply from that point forward. The Administrator may request a repeat performance test at any time.

(2) You must repeat the performance test within 60 days of a process change, as defined in § 60.5250.

(3) Except as specified in paragraphs (a)(1) and (2) of this section, you can conduct performance tests less often for a given pollutant, as specified in paragraphs (a)(3)(i) through (iii) of this

section.

(i) You can conduct performance tests less often if your performance tests for the pollutant for at least 2 consecutive years show that your emissions are at or below 75 percent of the emission limit specified in Table 2 or 3 to this subpart, and there are no changes in the operation of the affected source or air pollution control equipment that could increase emissions. In this case, you do not have to conduct a performance test for that pollutant for the next 2 years. You must conduct a performance test during the third year and no more than 37 months after the previous performance test.(ii) If your SSI unit
continues to meet the emission limit for the pollutant, you may choose to conduct performance tests for the pollutant every third year if your emissions are at or below 75 percent of the emission limit, and if there are no changes in the operation of the affected source or air pollution control equipment that could increase emissions, but each such performance
test must be conducted no more than 37 months after the previous performance

test.

(iii) If a performance test shows emissions exceeded 75 percent of the emission limit for a pollutant, you must conduct annual performance tests for that pollutant until all performance tests over 2 consecutive years show compliance.

(b) Demonstrate continuous compliance using a continuous emissions monitoring system or continuous automated sampling system. The option to use a continuous emissions monitoring system for hydrogen chloride, dioxins/furans, cadmium, or lead takes effect on the date a final performance specification applicable to hydrogen chloride, dioxins/furans, cadmium, or lead is published in the Federal Register . The option to use a continuous automated sampling system for dioxins/furans
takes effect on the date a final performance specification for such a continuous automated sampling system is published in the Federal Register

. Collect data as specified in § 60.5220(b)(6) and use the following procedures:

(1) To demonstrate continuous compliance with the emission limits for particulate matter, hydrogen chloride, carbon monoxide, dioxins/furans (total mass basis or toxic equivalency basis), mercury, nitrogen oxides, sulfur dioxide, cadmium, and lead, you may
substitute the use of a continuous monitoring system in lieu of conducting the annual performance test required in paragraph (a) of this section, as follows:

(i) You may substitute the use of a continuous emissions monitoring system for any pollutant specified in paragraph (b)(1) of this section in lieu of conducting the annual performance test for that pollutant in paragraph (a) of this section. For determining compliance
with the carbon monoxide concentration limit using carbon monoxide CEMS, the correction to 7 percent oxygen does not apply during periods of startup or shutdown. Use the
measured carbon monoxide concentration without correcting for oxygen concentration in averaging with
other carbon monoxide concentrations (corrected to 7 percent oxygen) to determine the 24-hour average value.

(ii) You may substitute the use of a continuous automated sampling system for mercury or dioxins/furans in lieu of conducting the annual mercury or dioxin/furan performance test in paragraph (a) of this section.


### 15440 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

(2) If you use a continuous emissions monitoring system to demonstrate compliance with an applicable emission limit in paragraph (b)(1) of this section, you must use the continuous emissions monitoring system and follow the requirements specified in § 60.5220(b). You must measure emissions according to § 60.13 to calculate 1-hour arithmetic averages, corrected to 7 percent oxygen (or carbon dioxide). You must demonstrate initial compliance using a 24-hour block average of these 1-hour arithmetic average emission concentrations, calculated using Equation 19–19 in section 12.4.1 of Method 19 of 40 CFR part 60, appendix

A–7.

(3) If you use a continuous automated sampling system to demonstrate compliance with an applicable emission limit in paragraph (b)(1) of this section,
you must:

(i) Use the continuous automated sampling system specified in § 60.58b(p) and (q), and measure and calculate average emissions corrected to 7 percent oxygen (or carbon dioxide) according to § 60.58b(p) and your monitoring plan.

(A) Use the procedures specified in § 60.58b(p) to calculate 24-hour averages to determine compliance with the mercury emission limit in Table 2 to this subpart.

(B) Use the procedures specified in § 60.58b(p) to calculate 2-week averages to determine compliance with the dioxin/furan (total mass basis or toxic equivalency basis) emission limits in Table 2 to this subpart.

(ii) Update your monitoring plan as specified in § 60.4880(e). For mercury continuous automated sampling systems, you must use Performance Specification 12B of appendix B of part 75 and Procedure 5 of appendix F of this part.

(4) Except as provided in paragraph (e) of this section, you must complete your periodic performance evaluations required in your monitoring plan for any continuous emissions monitoring systems and continuous automated sampling systems, according to the schedule specified in your monitoring plan. If you were previously determining compliance by conducting an annual performance test (or according to the less frequent testing for a pollutant as provided in paragraph (a)(3) of this section), you must complete the initial performance evaluation required under your monitoring plan in § 60.5200 for the continuous monitoring system prior to using the continuous emissions monitoring system to demonstrate compliance or continuous automated sampling system. Your performance evaluation must be conducted using the procedures and acceptance criteria specified in § 60.5200(a)(3).

(c) To demonstrate compliance with the dioxins/furans toxic equivalency emission limit in paragraph (a) or (b) of this section, you must determine dioxins/furans toxic equivalency as
follows:

(1) Measure the concentration of each dioxin/furan tetra- through octachlorinated-isomer emitted using Method 23 at 40 CFR part 60, appendix

A–7.

(2) For each dioxin/furan (tetrathrough octachlorinated) isomer measured in accordance with paragraph (c)(1) of this section, multiply the isomer concentration by its corresponding toxic equivalency factor specified in Table 5 to this subpart.

(3) Sum the products calculated in accordance with paragraph (c)(2) of this
section to obtain the total concentration
of dioxins/furans emitted in terms of toxic equivalency.

(d) You must submit an annual compliance report as specified in § 60.5235(c). You must submit a deviation report as specified in § 60.5235(d) for each instance that you
did not meet each emission limit in Table 2 to this subpart.

(e) If you demonstrate continuous compliance using a performance test, as specified in paragraph (a) of this section, then the provisions of this paragraph (e) apply. If a force majeure is about to occur, occurs, or has occurred for which you intend to assert a claim of force majeure, you must notify the Administrator in writing as specified in § 60.5235(g). You must conduct the performance test as soon as practicable after the force majeure
occurs. The Administrator will determine whether or not to grant the extension to the performance test deadline, and will notify you in writing of approval or disapproval of the request for an extension as soon as practicable. Until an extension of the performance test deadline has been approved by the Administrator, you remain strictly subject to the requirements of this subpart.

(f) After any initial requests in § 60.5200 for alternative monitoring requirements for initial compliance, you may subsequently petition the Administrator for alternative monitoring parameters as specified in §§ 60.13(i) and 60.5200(e).

demonstrates that no corrective action is required, no alarm time is counted.

(B) If corrective action is required,
each alarm time shall be counted as a
minimum of 1 hour.

(C) If you take longer than 1 hour to initiate corrective action, each alarm time ( i.e., time that the alarm sounds) is
counted as the actual amount of time taken by you to initiate corrective

action.

(ii) Your maximum alarm time is equal to 5 percent of the operating time during a 6-month period, as specified in § 60.5170(c).

(b) Operation above the established maximum, below the established minimum, or outside the allowable range of the operating limits specified in paragraph (a) of this section constitutes a deviation from your operating limits established under this subpart, except during performance tests conducted to determine compliance with the emission and operating limits or to establish new operating limits.

(ii) Safe sampling platform(s). (iii) Safe access to sampling platform(s).

(iv) Utilities for sampling and testing equipment.

(10) Unless otherwise specified in this subpart, each performance test must consist of three separate runs using the applicable test method. Each run must
be conducted for the time and under the conditions specified in the applicable standard. Compliance with each


### 15442 Federal Register / Vol. 76, No. 54 / Monday, March 21, 2011 / Rules and Regulations

emission limit must be determined by calculating the arithmetic mean of the three runs. In the event that a sample is accidentally lost or conditions occur in
which one of the three runs must be
discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances, beyond your control, compliance may, upon the Administrator’s approval, be determined using the arithmetic mean
of the results of the two other runs.
