Conditions for N-339-17-10 (continued) Page 4 of 9 42. Annual amount of soil used for intermediate and final covering shall not exceed 1,406,527 cubic yarcls of soil, and PM 10 emissions shalt not cxc=tl 0.0061b PM 10/ton of soil (using, a soil density of 3,240 lbs/cubic yard of soil). Permittee shall keep annual records of the amount of soil used for intermediate and final covering, (District NSR Rule) Fedcrully )enforceable Through Title V Permit 43. Permittee shall maintain daily and annual records otlandfill gas flow rate to the flares. [District Rule 10701 Federally Enforceable Through Title V Permit 44. All records shall be retained for a period of at least 5 years and shall be made available for District inspection upon request. (District R.ulc 10701 Federally Enforceable Through Title V permit 45. A record of continuous flare combustion temperature, continuous volumetric gas flow rate, net heating value of landfill gas being combusted, daily average fuel consumption, daily average heat input, and carbon canister inspection shall be maintained, retained on the premises for a period of at least five years and made readily available for District inspection upon request. [District NSR Rule] federally Fnforccablc Through Title V Permit 46. This opcniting permit may be cancelled with APCO approval when the landfill is closed, pursuant to the requirements of this permit, if IN; landfill is not otherwise subject to the requirements of either 40 CFR part 70 or part 71 and if either 1) it was never subject to the requirement for a control system tinder 40 CFR 60.752(b)(2); or 2) the owner or operator meets the conditions for control system removal specified in 40 CFR 60.752(b)(2)(v). [40 CFR 60.752(d)] Federally Enforecable'Through Title V Permit 47. If the landfill is permanently closed, a closure notification shall be submitted to the APCO within 30 days of waste disposal cessation. A permanent closure must take place in accordance with 40 CI:R 258.60. if a closure report has been submitted, no additional waste may be placed in the landitlI without tiling a notification of modification to the APCO, pursuant to 40 CFR 60.7(a)(4). [40 CFR 60.752(b)(1)(iiXR), 60.757(4)) 4S. An active collection system shall be designed to handle the maximum expected gas Clow rate from the entire area of the landfill that warrarnt.s control over the intended use period of the gas control or treatment system equipment, collect has from each area, cell, or group of cells in the landfill in which the initial solid waste has tint placed for a period of 5 years or more if active; or 2 years or more if closed or at final grade, collect gas at a sufficient extraction rate, and be designed to minimiic; off-site migration ofsubsurfacc gas. [40 CYR 60.752(b)(2)(ii)(A)] Federally rinlorceable Through Title: V Permit 49. All collected gas shall be routed to a control system designed and operated to reduce the NMOC by 99 weight percent or reduce the outlet NMOL concentration to less than 20 parts per million by volume, dry basis as hexane at 3 percent oxygen. The reduction efficiency shall be established by an initial performance test w be completed no later than 180 days after the initial startup of the approved control system using the test methods specified in Section 60.754(4). [40 CFR 60.752(bx2)(iii)(B)] Federally Enforceable Through Title V Permit 50. Permittee shall operate the collection system so that the methane concentration is less than 500 parts per million above background at the surface of t.hc landfill. To determine if this level is exceeded, the owner or operator shall conduct surface tcating around the perimeter of the collection area and along a pattern that traverses the landfill at 30 meter intervals and where visual observations indicate elevated concentrations of landfill gas, such as distreswd vegetation and cracks or seeps in the cover. The owner or operator may establish an alternative traversing pattern that ensures equivalent coverage. A surface monitoring design plait shall be developed that includes a topographical map with the monitoring route and the rationale for any site-specific deviations from the 30 meter intervals. Areas with steep slopes or other dangerous areas may he excluded from the surface testing. [40 CFR 60.753(d)] Federally Enforccablc Through Title V Permit 51. Compliance with this surface methane operational standard shall be demonstrated using the procedures outlined in 40 CFR 60.755(c) within 180 days of installation and startup of the collection and control system and quarterly thereafter. (40 CFR 60.753(d), 40 CFR 60.755(c), and 40 CFR 60.6] Federally Enforecabic Through 11de V Permit 52. Pumiittc a shall operate the enclosed flare at all times when the collected gas is routed to it. [40 CFR 60.753(01 federally Enforceable Through Title V Permit 53. Pcrmittcc shall operate the landfall gas collection system such that gas is cullcctcd from each area, cell, or group of cells in the MSW landfill in which solid waste has been in place for- (1) five years or more if active; or (2) two years or more if closed or at final graft.
