0332070 Chanton The objectives of the proposed research are to:1. Evaluate the performance of biocovers placed over the surface of landfill caps in field test plots. A biocover consisting of a 30 cm layer of gravel for gas dispersion overlain by a meter of mixed woodchips and mature composted yard waste would be constructed and monitored for methane emission and oxidation over 2 annual cycles.2. Evaluate the performance of biofilters to eliminate methane emissions and attenuate non methane organic compound (NMOC) emissions from passive vents. Performance based designs for these systems would be the product of this research. Prospective applications of biocovers in the U.S. include landfills which are too small for commercial gas extraction, where gas production has declined beyond the point of commercial interest, where gas extraction is not required under U.S. EPA Clean Air Act Amendments, leaky areas or hot spots, or where interim cover will be in place for a substantial period of time before additional filling and eventual gas extraction.

拟议研究的目标是：1。在实地试验田评估覆盖在垃圾填埋盖表面的生物覆盖物的性能。一个生物覆盖层由一层30厘米的砾石层组成，用于气体分散，上面覆盖一米的混合木片和成熟的堆肥庭院废物，并监测甲烷排放和氧化，为期2年。评估生物过滤器消除甲烷排放和减弱被动喷口非甲烷有机化合物（NMOC）排放的性能。这些系统的基于性能的设计将是本研究的成果。生物覆盖物在美国的潜在应用包括：对于商业天然气开采来说规模太小的垃圾填埋场、天然气产量已经下降到超过商业利益点的地方、美国环保署清洁空气法案修正案不需要天然气开采的地方、泄漏区域或热点地区，或者在额外填充和最终天然气开采之前将在相当长的一段时间内实施临时覆盖物的地方。
