Section 115.152 - Control Requirements(a) For the Houston/Galveston, El Paso, and Dallas/Fort Worth ozone nonattainment areas as defined in § 115.10 of this title (relating to Definitions), no person shall operate or allow the operation of a municipal solid waste landfill (MSWLF) unless each owner or operator of an MSWLF calculates the nonmethane organic compounds (NMOC) emission rate for the landfill using the procedures provided in §60.753 of the proposed federal rules published in the May 30, 1991, issue of the Federal Register (58 FR 104). The volatile organic compound emission rate shall be calculated and recalculated annually using the following default values: Generation Rate Constant, K = 0.05 1/year; Generation Potential, L o = 170 m3 /Mg; Non-methane Gas Concentration, CNMOC = 4,000 ppmv. If at any time the calculated NMOC emission rate exceeds 150 Megagrams (Mg) per year, the owner or operator shall:(1) install a gas collection and control system (GCCS) subject to the requirements of §60.752(b)(2)(ii) of the proposed federal rules published in the May 30, 1991, issue of the Federal Register (58 FR 104). Alternative design methodologies to the GCCS are subject to the approval of the executive director;(2) control NMOC gas emissions in one of the following ways: (A) the total collected gas is routed to an open flare designed and operated in accordance with 40 CFR §60.18;(B) the total collected gas is routed to a control device which reduces the total collected gas emissions by 98% or to less than 20 parts per million by volume; or(C) the total collected gas is routed to a gas treatment system which processes the collected gas for subsequent use or sale. The sum of all emissions from any atmospheric vent from the gas treatment system shall be subject to the requirements of subparagraph (A) of this paragraph;(3) operate the GCCS in compliance with §60.754 of the proposed federal rules published in the May 30, 1991, issue of the Federal Register (58 FR 104).(b) The GCCS may be capped or removed if all of the following conditions are met: (1) the landfill shall no longer accept waste and shall be permanently closed;(2) the GCCS shall have been in continuous operation for at least 15 years; and(3) the calculated NMOC emission rate shall be less than 150 Mg per year on three successive test dates. The test dates shall be no closer than three months apart, and no longer than six months apart.30 Tex. Admin. Code § 115.152
