refuse derived fuel plus waste to energy. The County received this report in August 2008 and it is available on the County web site or on request. Following the December 2009 decision not to site a transfer station in Orange County for at least three to five years,various citizens and citizen groups have urged the County to consider other alternative technologies for handling the county's solid waste and possibly other wastes such as biosolids, medical waste and other difficult to manage materials. The SWAB was directed, as part of the decision to consider various alternatives further. In Apri12010 the SWAB hosted its first presentation of the plasma arc technology by inventor Dr.Louis Circeo of Georgia lnstitute of Technology. T'he SWAB will conduct future technology reviews and presentations with a report back to the board projected in 2011 following completion of more comprehensive review. In 2009-10 the County and LTNC concluded a landfill gas recovery agreement for Orange County's lined MSW landfill and closed MSW unlined landfill. LJNC is to capitalize the project and own the gas, infrastructure and any related carbon credits associated with recovering the methane. Orange County will receive payment based on contractual provisions. Construction is slated to start in November 2010 and gas recovery to begin in mid-2011. Gas will initially be flared and then eventually piped to an off-site generator on University property to generate electricity for use on iJNC property. Environmental Monitorin� On-site inspectors at the working face scrutinize all incoming waste for the presence of regulated recyclable materials. Penalties are levied on loads out of compliance or the haulers are given the option to remove the offending materials. County facilities have 36 monitoring groundwater monitoring wells and sample 28 wells semi- annually for the criteria pollutants of pH, conductivity,temperature,total metals as well as volatile organics using EPA method 8260 and an inorganic analysis for lead,barium, cadmium, chromium, lead, mercury, selenium and silver. To monitor methane we have 18 gas-monitoring probes on the north side and 19 gas monitoring probes on the south side. We discovered in winter of 09-10 a methane migration and controlled it by installation of a localized trench system. Seven gas flares are currently used to reduce odor problems, which have unfortunately persisted. There are also 45 passive gas- venting pipes in the closed north MSW landfill that are not monitored directly but control gas flow direction. A subsidence in 2009 at the closed MSW landfill was controlled with soil fill. Planning Approach and Pro�ress Towards Waste Reduction and Disposal Goa1s While Orange County is the lead agency in overall solid waste management in Orange County, it continues to actively engage with its partners,the three Towns and i1NC as well as citizens and businesses overall. There is a general understanding since the first plan submittal in 1997,that a single integrated plan will be submitted by all the partners and a specific reaffirmation of the 61%waste reduction goal in the resolution from each government attached to each plan submittal. There is an operating interlocal agreement which stipulates all waste controlled by the four local governments is to be delivered to the Orange County landfill. As long as the landfill and other related facilities are operational,the partners will continue to deliver waste there. 10
