Permit Unit Requirements for N-339-17-7 (continued) Page 4 of 6 <br />42. If the calculated NMOC mass emission rate, using the site-specific NMOC concentration, is less than 50 <br />megagrams/year, then a periodic estimate of the emission rate report, pursuant to 60.757(b)(1) shall be submitted to the <br />Administrator. The site-specific NMOC concentration shall be retested every 5 years, using Tier 2 specifications. [40 <br />CFR 60.754(a)(3)(iii)] Federally Enforceable Through Title V Permit <br />43. Tier 3 specifications to determine the site-specific methane generation rate constant shall include the following: 1) <br />EPA Method 2E or another method approved by the EPA shall be used, 2) The NMOC mass emission rate shall be <br />recalculated using the average site-specific NMOC concentration and the site-specific methane generation rate <br />constant k, instead of the default values in 40 CFR 60(a)(1), and 3) If the resulting calculated NMOL mass emission <br />rate is equal to or greater than 50 megagrams/year, the landfill owner or operator shall comply with 60.752(b)(2). [40 <br />CFR 60.754(a)(4), (a)(5) and (i)) Federally Enforceable Through Title V Permit <br />44. If Tier 3 specifications are used to determine the site-specific methane generation rate and the calculated NMOL mass <br />emission rate is less than 50 megagrams/year, then a periodic emission rate report shall be submitted to the <br />Administrator, pursuant to 60.757(b)(1) and the NMOC concentration shall be recalculated annually, pursuant to <br />60.757(b)(1), using the site-specific methane generation rate constant and the NMOL concentration obtained using <br />Tier 2 specifications. Determination of the site-specific methane generation rate constant is performed once and used <br />in all subsequent annual NMOC emission rate calculations. [40 CFR 60.754(a)(4)(ii)] Federally Enforceable Through <br />Title V Permit <br />45. For PSD purposes, the NMOL emission rate shall be estimated and compared to the PSD major source and <br />significance levels in 40 CFR 51.166 or 52.21, using AP42 or EPA -approved procedures. [40 CFR 60.754(c)] <br />Federally Enforceable Through Title V Permit <br />46. The NMOL emission rate shall be recalculated and reported to the APCO annually, except as otherwise provided in <br />this permit, until such time as the calculated NMOC emission rate is equal to or greater than 50 megagrams/year and a <br />collection and control system is installed or until the landfill is closed. [40 CFR 60.752(b)(1), 60.754(a), and <br />60.757(b)] Federally Enforceable Through Title V Permit <br />7. If the NMOC emission rate, as reported in the annual report is less than 50 megagrams/year in each of the next 5 <br />consecutive years, the owner or operator may elect to submit an estimate of the NMOC emission rate for the next 5 - <br />year period in lieu of the annual reports for those 5 years. This estimate shall include the current amount of solid <br />waste -in-place and the estimated waste acceptance rate for each year of the 5 years. All data and calculations upon <br />which this estimate is based shall be provided to the APCO. This estimate shall be revised at least once every 5 years. <br />[40 CFR 60.757(b)(1)(ii)] Federally Enforceable Through Title V Permit <br />48. If the actual waste acceptance rate exceeds the estimated rate used in any year reported in a 5 -year estimate of the <br />NMOC emission rate, then a revised 5 -year estimate shall be submitted to the APCO. The revised estimate shall cover <br />the 5 -year period beginning with the year in which the actual waste acceptance rate exceeded the estimated acceptance <br />rate. [40 CFR 60.757(b)(1)(ii)] Federally Enforceable Through Title V Permit <br />49. The NMOC emission rate report shall include all the data, calculations, sample reports and measurements used to <br />estimate the annual or 5 -year emissions. [40 CFR 60.757(b)(2)] Federally Enforceable Through Title V Permit <br />50. If the owner or operator elects to recalculate the NMOC emission rate using Tier 2 specifications and the resulting <br />NMOC emission rate is less than 50 megagrams/year, annual periodic reporting shall resume. The revised NMOC <br />emission rate report, with the recalculated NMOC emission rate using Tier 2 specifications, shall be submitted within <br />180 days of the first Tier 1 calculated exceedance of 50 megagrams/year. [40 CFR 60.757(c)(1)] Federally Enforceable <br />Through Title V Permit <br />51. If the owner or operator elects to recalculate the NMOC emission rate using Tier 3 specifications and the resulting <br />NMOC emission rate is less than 50 megagrams/year, annual periodic reporting shall resume. The revised NMOL <br />emission rate report, with the recalculated NMOC emission rate using Tier 3 specifications, shall be submitted within 1 <br />year of the first Tier 1 calculated exceedance of 50 megagrams/year.
