Agency Information Collection Activities: Submission for OMB Review; Comment Request; Reporting and Recordkeeping Requirements for the New Source Performance Standards for Municipal Solid Waste Landfills

Title: Reporting and Recordkeeping Requirements for the New Source Performance Standards for Municipal Solid Waste Landfills (OMB Control No. 2060-0220; EPA ICR No. 1557.04) expiring 8/31/99. This is a request for extension of a currently approved collection. Abstract: In the Administrator's judgement municipal solid waste (MSW) landfill emissions generated by decomposition of municipal solid waste deposited in an MSW landfill may reasonably be anticipated to endanger public health or welfare. Therefore, NSPS were promulgated for this source category. All respondents must submit an initial design capacity report which includes the landfill's maximum design capacity, date of anticipated startup, and the anticipated refuse acceptance rate. If the design capacity of a new landfill is less than 2,500,000 megagrams (Mg), no further reporting or recordkeeping is required. Under certain circumstances, amended design capacity reports may be required. If the facility's design capacity is equal to or greater than 2,500,000 Mg, the owner or operator is required to determine the facility's nonmethane organic compound (NMOC) emission rate. If the NMOC emission rate is determined to be <50 Mg/yr, using Tier 1, Tier 2, or Tier 3 calculations, no further calculation or testing is required for that year. Owners or operators of MSW landfills emitting <50 Mg NMOC per year may submit reports of NMOC emission rates yearly. However, NSPS Subpart WWW, also allow owners or operators to report less frequently. Under these provisions, the NMOC report may be accompanied by an estimation of the annual NMOC emission rate for each of the next 5 years, provided that none of the estimated rates reaches 50 Mg/yr. In this case, the owner or operator would not submit annual reports, but the estimation would be updated and resubmitted every 5 years. The owner or operator would also be required to revise the estimate in any year in which the actual waste acceptance rate for that year exceeds the waste acceptance rate upon which the previously submitted estimate is based. Owners or operators of landfills with collection and control systems installed in compliance with the standards are not required to submit reports of NMOC emission rates. Owners or operators of affected facilities would be required to keep records of accumulated refuse and waste acceptance rates for a minimum of 5 years. For landfills required to install collection and control systems (i.e., those emitting greater than 50 Mg/yr of

NMOC), submission of a collection and control system design plan is required. After review of the design plan and installation of the collection and control system, an initial performance test and report for the system is required. Thereafter, annual compliance reports would be required. For control systems using an enclosed combustion device, the initial performance test would also include the average combustion temperature, and the percent reduction of NMOC achieved. For control systems using a boiler, the initial performance report would include a description of the location at which the emission stream is introduced into the boiler, and the average combustion temperature of the boiler. For control systems using an open flare, the initial performance report would include a description and the flare type, visible emissions reading, a heat content determination, flow rate measurements, and exit velocity determinations. Where control devices other than an open flare or closed combustion device are used, owners or operators would be required to submit to the Administrator information describing the control device and parameters that will indicate its proper performance. Following submission of the initial performance report, owners or operators would be required to keep continuous monitoring records of the parameters reported in the initial performance report and records of monthly monitoring of the collection system and quarterly monitoring of surface methane concentration. Annual compliance reports and recordkeeping would include descriptions of any periods in which the value of any of the monitored operating parameters falls outside the established ranges and any period when the collection system or air pollution control equipment malfunctioned or when the collected gas was diverted from the control device. When applicable, each owner or operator of a controlled landfill will submit a closure report to EPA within 30 days of waste acceptance cessation. The information collected will be used by EPA personnel to ensure compliance with the NSPS and identify the sources subject to the standards. When appropriate under NSPS, Subpart WWW, each owner or operator of a controlled landfill shall submit annual reports of exceedances, gas steam diversion, control device non-operation, collection system failure, the date at installations and the location of each well or well collection system and equipment removal. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15. The Federal Register document required under 5 CFR 1320.8(d), soliciting comments on this collection of information was published on 1/5/99 (64 FR 499); no comments were received. Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 11.3 hours per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. Respondents/Affected Entities: Owners or Operators of MSW landfills for which construction, modification, or reconstruction commences on or began accepting waste after May 30, 1991. Estimated Number of Respondents: 172 each year. Frequency of Response: quarterly, annually. Estimated Total Annual Hour Burden: 3,379 hours. Estimated Total Annualized Cost Burden: $80,000. Send comments on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques to the following addresses. Please refer to EPA ICR No. 1557.04 and OMB Control No. 2060-0220 in any correspondence.
