Conditions for N-339-17-10 (continued) Page 8 of 9 86. Eich owner or operator sceleing to comply with 40 CFR 60.752(b)(2)(i) .,hall site active collection wells, horizontal coll"lors, surface collectors, or othcr extraction device.% at a sufficient density throughout all gas producing area,% using the following procedures unless alternative procedures have been approved by the APCO its provided in 60.752(b)(2)(i)(C) and (D). [40 CFR 60,759(x)) Federally Enforceable Through Titic V Permit 87. The collection devices within the interior and along the perimeter areas shall be certified to achieve comprehensive control of surface gas emissions by a professional engineer. The following issues shall be addressed in the design: depths of refuse, refuse gas generation rates and flow characteristics, cover properties, gas system expandability, leachate and condensate management, accessibility, compatibility with filling operations, integration with closure end use, air intrusion control, corrosion resistance, fill settlement, and resistance to the refuse decomposition heat. 140 CFR 60.759(x)(1)] Federally linforceableThrough Title V ltennit 88. The placement of gas collection devices determined in paragraph 60.759(a)(i.) shall control all gas prod"ing areas, except as provided by paragraphs 60.759(a)(3Xi) and (a)(3)(ii). [40 CFR 60.759(ax3)] Federally Enforceable Through Title V Permit 89. The sufficient density of gas collection devices determined in paragraph 60.759(a)(1) shall address landfill gas migration issues and augmentation of the collection system through the use of active or passzive systems at the landfill perimeter or exterior. [40 CFR 60.759(x)(2)] Federally Enforceable Through Tit1u V Permit 90. Any segregated area of asbestos or nondegradable material may be excluded from collection if documented as provided under 60.758(d). The documunuetion shall provide the naturu, date of deposition, location and amount of asbestos or nondegradable material deposited in the area, and shall he provided to the Administrator upon request. lot} CFR 60.759(a)(3)(i)j federally Enforceable Through Title V Permit 91. Any nonproductive area of the landfill may bu uxcluded from control providW that the total of all excluded areas can be shown to contribute less than 1 percent of the total amount of KMOC emissions from the landfill. The amount, location, and ago of the material shall be documented and provided to the: Administrator upon request. A separate NMOL emissions estimate shall be nuide for each section proposed for exclusion, and the sum of all such scetions shall be compared to the NMOC emissions estimate for the entire landfill. Emissions from each section shall be computed using the equation in Section 60.759(a)(3)(ii). 140 CPR 60.759(a)(3)(ii)) Federally Enforceable Through Title V Permit 92. The values for k and CNM6C in equation in Section 60.759(n)(3xii) determined in field testing shall be uwd if field testing has been performed in determining the NMOL emission rate or the radii of influence (this distance from the well center to a point in the landfill where the pressure gradient applied by the blower or compressor approaches zero). 1f field te-Ming has not beets performed, the default values for k, Lo, and CNMOC provided in 60.754(a)(1) or the altemativc values from 60.754(x)(5) shall be used. Tate mass of nondegradable solid waste contained within the given section may be subtracted from the total mass of the section when estimating emissions provided the nature, Dation, agc, and amount of the nondegradable material is documented as provided in paragraph 60.759(a)(3)(i).
