Conditions for N-339-17-10 (continued) Page 8 of 9
<br /> 86. Each owner or operator seeking to comply with 40 CFR 60.752(b)(2)(i)shall site active collection wells,horizontal
<br /> collectors,surface collectors,or other extraction devices at a sufficient density throughout all gas producing areas
<br /> using the following procedures unless alternative procedures have been approved by the APCO as provided in
<br /> 60.752(b)(2)(i)(C)and(D).[40 CFR 60.759(a)]Federally Enforceable Through Title V Permit �-
<br /> 87. The collection devices within the interior and along the perimeter areas shall be certified to achieve comprehensive
<br /> control of surface gas emissions by a professional engineer. The following issues shall be addressed in the design.
<br /> depths of refuse,refuse gas generation rates and flow characteristics,coverproperties,gas system expandibility,
<br /> leachate and condensate management,accessibility,compatibility with filling operations,integration with closure end
<br /> use,air intrusion control,corrosion resistance,fill settlement,and resistance to the refuse decomposition heat.[40 CM
<br /> 60.759(a)(1)]Federally Enforceable Through'Title V Permit #'
<br /> 88. The placement of gas collection devices determined in paragraph 60.759(a)(1)shall control all gas producing areas,
<br /> except as provided by paragraphs 60.759(a)(3)(i)and(a)(3)(ii).[40 CCR 60.759(x)(3)]Federally Enforceable Through I
<br /> Title V Permit
<br /> 89. The sufficient density of gas collection devices determined in paragraph 60.759(a)(I)shall address landfill gas
<br /> migration issues and augmentation of the collection system through the use of active or passive systems at the landfill �.
<br /> perimeter or exterior.[40 CFR 60.759(a)(2))Federally Enforceable Through Title V Permit
<br /> 90. Any segregated area of asbestos or nondegradable material may be excluded from collection if documented as '
<br /> provided under 60.758(d). The documentation shall provide the nature,date of deposition,location and amount of
<br /> asbestos or nondegradable material deposited in the area,acid shall be provided to the Administrator upon request.[40
<br /> CFR 60.759(a)(3)(i)]Federally Enforceable Through Title V Permit
<br /> 91. Any nonproductive area of the landfill may be excluded from control provided that the total of all excluded areas can
<br /> be shown to contribute less than I percent of the total amount of NMOC emissions from the landfill, The amount,
<br /> location,and age of the material shall be docuiiiented and provided to the Administrator upon request. A.separate j
<br /> NMOL emissions estimate shall be made for each section proposed for exclusion,and the sum of all such sections
<br /> shall be compared to the NMOC emissions estimate for,the entire landfill. Emissions from each section shall be
<br /> computed using the equation in Section 60.759(a)(3)(ii).[40 CFR 60,759(a)(3)(ii)]Federally Enforceable Thrpugh
<br /> Title V Permit
<br /> 92. The values for k and CNMOC in equation in Section 60.759(a)(3)(ii)deteimined in field testing shall be used if field 1
<br /> testing(las been performed in determining the NMOC emission rate or the radii of influence(this distance from the
<br /> well center to a point in the landfill where the pressure gradient applied by the blower or compressor approaches zero), j
<br /> If field testing has not been performed,the default values for k,Lo,and CNMOC provided in 60.754(a)(1)or the i
<br /> alternative values from 60.754(a)(5)shit[[be used. The mass of uondegradable solid waste containedwithin the given
<br /> section may be subtracted from the total mass of the section when estimating emissions provided the mature,location,
<br /> age,and amount of the nondegradable material is documented as provided in paragraph 60.759(a)(3)(i).[40 CFR
<br /> 60.759(a)(3)(iii)]Federally Enforceable Through Title V Permit i
