A Summary of Comments and Questions—EPA Responses
https://www.federalregister.gov/d/03-31866 https://www.federalregister.gov/d/03-31866
EPA is approving the Commonwealth of Pennsylvania (the Commonwealth) municipal solid waste landfill plan (the plan) for implementing emission guideline (EG) requirements promulgated under the Clean Air Act (the Act). The plan establishes enforceable nonmethane organic compounds (NMOC) emissions limits for existing landfills within the Commonwealth, excluding the geographic areas under the authority of Allegheny County and the City of Philadelphia.
On June 24, 2003, EPA published a direct final rule (68 FR 37421) approving the Pennsylvania section 111(d) landfill plan (the plan). Also, on that date, EPA published a proposed rule (68 FR 37449) to allow interested parties to submit comments. During the public comment period, EPA received numerous adverse comments and questions from The Alliance for A Clean Environment (ACE). As a result, on August 19, 2003, EPA withdrew the direct final rule granting approval of the Pennsylvania plan (68 FR 49706).
Many of the comments and questions EPA received from ACE ( the “commenter”) are not relevant or germane to the Pennsylvania plan approval process in the context of section 111(d) Clean Air Act requirements, and the related regulatory provisions of 40 CFR part 60, subparts B, Cc, and WWW. In this section of the Federal Register notice, EPA is responding primarily to those adverse comments and questions that possibly could be considered relevant or germane to the plan approval process in the context of section 111(d) requirements only. The many ACE comments and questions, which are not relevant to the plan approval, address the following generic and source specific issues:
(a) Ambient air quality and emission standards for criteria pollutants, and related health impacts, as regulated under section 110 of the Act;
(b) Toxic air pollutants, and related health impacts, as regulated under section 112 of the Act;
(c) Radioactive landfill gas emissions, and related health impacts;
(d) Suggested revisions or amendments to EPA's promulgated landfill rules—EG and new source performance standards ( NSPS ); and
(e) Clean Air Act violations at a specific landfill facility and EPA's enforcement response.
All of the above listed issues are beyond the scope of EPA's section 111(d) plan requirements and approval authority. Any ACE issue, which is not listed generically above is also considered irrelevant to this plan approval action. EPA's responses to possible relevant issues and questions are given below.
1. How were Pennsylvania communities notified that they had an opportunity to comment on the plan? Response—Three separate PADEP public hearings were held on the plan in June 1997. Prior to each hearing, a thirty (30) day notice was published in one or more newspapers that serve the public hearing site area. These notices were published in six (6) prominent Pennsylvania newspapers and the Pennsylvania bulletin. The PADEP has met EPA's public notification and public participation requirements of 40 CFR 60.23. This is discussed in EPA's June 24, 2003 Federal Register notice (68 FR 37421), paragraph II. J, A Record of the Public Hearing on the State Plan.
2. On what basis does EPA view the plan approval as a non-controversial action? Response—EPA's action is based on section 111(d) requirements of the Act, not sections 110 and 112, relating to state plans and requirements for criteria (e.g., ozone) and hazardous (e.g., dioxins/furans, mercury compounds, and radionuclides) air pollutants, respectively. The Pennsylvania landfill plan contains requirements that are no less stringent than those required by section 111(d) of the Act and the related provisions of 40 CFR part 60, subparts B and Cc. Also, the plan contains Start Printed Page 74869facility specific compliance schedules that are expeditious, as required by subpart B, and require final compliance by a date earlier than that of the generic compliance schedule under the Federal Plan, 40 CFR part 62, subpart GGG, promulgated on November 8, 1999. The Federal plan is applicable to all affected landfills located in those states without an approved plan, such as Pennsylvania, until the state plan is approved by EPA. The Pennsylvania plan meets all applicable federal requirements, as discussed in EPA's June 24, 2003 Federal Register notice and the related technical support document (TSD).
3. What does “controlled” mean to EPA? Response—Section 111 of the Act requires EPA to promulgate EG and NSPS based on the application of what is referred to as best demonstrated technology (BDT), considering costs and any nonair quality health and environmental impacts and energy requirements, at the time the EG and NSPS are promulgated. The EG and NSPS establish a nationwide minimum level of control, for specific stationary source categories, based on the use of BDT. BDT for landfills, emitting 50 megagrams per year of NMOC or more, requires the reduction of MSW landfill gas emissions with: (a) A well designed and operated gas collection system and (b) a control device capable of reducing NMOC in the collected gas by 98 weight percent. Both EPA landfill rules (the EG and NSPS) recognize that various combustion devices, including flares, can be an effective means of reducing, by 98% or better, the NMOC emissions collected from a landfill. The BDT requirements for landfills are stipulated in the promulgated March 12, 1996 MSW landfill EG and the related NSPS, subparts Cc and WWW, sections 60.33c(c); and 60.752(b)(2)(ii) and (iii), respectively. More details about landfill gas control technologies and their performance are discussed in the preamble to the proposed EPA landfill rules (56 FR 24476, May 30, 1991). Also, additional information is given in EPA's proposed landfill rule amendments, as published in the May 23, 2002 Federal Register (67 FR 36477).
4. EPA admits to the public health dangers of landfill gas (i.e., NMOC) emissions, so why wouldn't EPA require the safest technology? Response—Consistent with the requirements of section 111 of the Act, EPA's landfill rules set a nationwide minimum level of control based on the use of BDT. EPA believes BDT control alternatives are safe for the operators and impacted community, providing the control equipment is properly designed, constructed, and operated. Because NMOC are health-related, states plans must ordinarily be at “least as stringent” as the EG. However, nothing under EPA's section 111 plan regulations, 40 CFR part 60, subpart B, prohibits the PADEP from adopting and enforcing more stringent emission standards. Nevertheless, the submitted Pennsylvania plan control requirements are no less stringent than BDT, as stipulated and required in subpart B and the EG, subpart Cc.
5. Does Pennsylvania have the legal authority to do anything about Clean Air Act [MSW landfill rule] violations in the past? Response—A state can only enforce section 111(d) plan requirements if (a) it has received EPA approval of the state plan, or (b) it has requested and received delegation of the Federal plan, 40 CFR part 62, subpart GGG. Neither is the case with the PADEP. At this time, the PADEP can enforce state only requirements. When EPA approves the Pennsylvania plan, PADEP will then have the authority under federal law to enforce the state plan , including possible “past” violations. PADEP has satisfactorily demonstrated its authority to implement the state plan, as stated in EPA's approval notice (68 FR 37422) of June 24, 2003.[1]
6. Why hasn't the Pottstown Landfill been included in this source inventory? Response—Any landfill that was modified or reconstructed after May 30, 1991 is subject to subpart WWW, and not the requirements of section 111(d) of the Act. A modification occurs if there is a physical change at the landfill that increases the capacity of the landfill beyond its permitted capacity. Based on documents from the PADEP and the Pottstown's landfill engineer, the landfill is a modified source, and thus subject to the NSPS, subpart WWW, and not section 111(d) requirements of either the Pennsylvania or Federal plan. Although the landfill EG and NSPS both require use of the same BDT, both stipulate different initial reporting and final compliance date requirements. However, if we assume that the Pottstown Landfill is a designated facility, subject to section 111(d) requirements, and was somehow overlooked in the Pennsylvania plan inventory, EPA's earlier plan approval notice (68 FR 37424) states, “ * * * if an unknown designated landfill is not covered by the scope of this plan and is discovered after EPA plan approval, that landfill will be subject to the promulgated Federal plan requirements until the PADEP amends its plan to include the previously unknown designated landfill.” In other words, under EPA's approval action, the Pottstown landfill would be covered by the promulgated Federal plan, even if at a later date it is determined that the facility is in fact subject to section 111(d) requirements.
7. With a health threat of NMOC emissions, why would a landfill get 21/2 years to comply? Response—Considering the size and NMOC applicability thresholds of affected landfills, EPA believes 21/2 years is generally expeditious. This timeframe is reflected in the promulgated EG, NSPS, and the Federal plan. As noted above, the Pennsylvania plan requires final compliance earlier than what is stipulated in the Federal plan.
8. How is the applicability threshold (50 megagrams per year) determined and by whom? Response—The measurement methods, applicable to both existing and new landfills, are specified in the landfill NSPS at section 60.754, Test Methods and procedures. Although the landfill owner/operator conducts the tests, both PADEP and EPA have oversight authority and can require a source retest with regulatory personnel on site during the test.
9. Were violations reported to EPA by PADEP under the plan provision that requires state submittal of annual reports on plan enforcement? Response—Under the plan, the noted reports are not due until one year after EPA approval of the plan. See the EPA Federal Register notice of June 24, 2003 (68 FR 37423), section II. K, Provision for Annual State Progress Reports to EPA. Within one year of EPA's approval of the plan, EPA expects the PADEP will begin submittal of annual compliance reports.
10. How were the people notified about changes to the original plan? Response—Other than changes in order to meet EPA promulgated revisions to the EG, we know of no plan changes, subsequent to its original submittal, that relaxes plan applicability, emission standards, operating requirements, recordkeeping and reporting, and compliance dates.
11. The commenter objects to PADEP's retention of source “trade secret” information, and its unavailability to the public, and questions what method or process trade secret information can be expected from operating a landfill. Response—It appears that PADEP's willingness to Start Printed Page 74870release all source compliance and emissions data, except for that relating to “trade secrets,” is consistent with EPA's subpart B requirements, 40 CFR 60.25(c). 40 CFR 60.25(c) only requires public access to compliance and emissions data that is correlated with applicable emissions standards (e.g., NMOC).
12. The commenter questions the Pennsylvania plan requirements regarding the frequency of emissions monitoring and the reliability of collected data. Response—The frequency of monitoring and the collection of reliable data are consistent with applicable EG requirements, 40 CFR 60.34c and 60.35c, as noted in EPA's June 24, 2003 Federal Register notice (68 FR 37423), and the related technical support document (TSD).
EPA is approving the Pennsylvania plan. This determination is based upon the rationale discussed in the proposed and related direct final rulemakings (68 FR 37449 and 37421, June 24, 2003) and EPA's evaluation of submitted public comments and questions, as dicussed above. Any revisions to the plan or associated landfill air quality operating permits will not be considered part of the applicable plan until submitted by the PADEP in accordance with the provisions of 40 CFR 60.28.
In reviewing 111(d) plan submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a 111(d) plan submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a 111(d) plan submission, to use VCS in place of a 111(d) plan submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by February 27, 2004. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action, approving the Pennsylvania section 111(d) MSW landfill plan, may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
40 CFR part 62, subpart NN, is amended as follows:
2. Sections 62.9635, 62.9636, and 62.9637 are added to subpart NN, “Landfill Gas Emissions From Existing Municipal Solid Waste Landfills” to read as follows:
Section 111(d) plan for municipal solid waste landfills, as submitted on July 1, 1997, and as amended through April 9, 2003 by the Pennsylvania Department of Environmental Protection. The plan excludes the Start Printed Page 74871geographical areas under the authority of Allegheny County and the City of Philadelphia.
1. With respect to the enforcement of NSPS requirements, on May 8, 1985, PADEP received automatic delegation of all NSPS from EPA. See the August 23, 1985 Federal Register. Accordingly, the PADEP has had the authority to enforce subpart WWW requirements since March 12, 1996, the date of rule promulgation
