one phone number email and web address for recycling and landfill information. Beginning in 2007-08 the Solid Waste Management Department also took managerial control of the Sanitation Division including five rurally located solid waste convenience centers, the County schools' waste collection and responsibility of ofF landfill litter control. Fiscally the centers, school waste collections and litter control activities remain part of the County's general fund budget, while the rest of the Solid Waste Management Department is funded through an enterprise fund, with income sources separate from the County's General Fund. Solid waste collection services are all privately provided in unincorporated Orange County. The three Towns all provide public waste collection to residential customers in their respective incorporated areas and a mix of public and private providers is used by commerciaUnon-residential entities in the incorporated areas. UNC provides most waste collection and recycling services by contract. The majority of waste generated in Orange County is delivered to the Orange County Landfill (see Table I). On-site inspectors at the working face scrutinize all incoming waste for the presence of regulated recyclable materials -- cardboard, metal and clean wood as well as for State or Federally banned materials including brush, batteries, tires, appliances, hazardous waste and infectious wastes. We have 35 monitoring groundwater monitoring wells as shown below. We sample 28 wells semiannually 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 The wells are distributed as follows: South Side MSW (active, line) - 14 wells: sample - 12 North side (closed MSW, 1995, unlined) - 16 wells: sample - 12 New C&D north side - 5 wells: sample - 4 To monitor methane we have 18 gas monitoring probes on the north side and 19 gas monitoring probes on the south side. We take gas readings quarterly. Through this testing we recently discovered a methane migration at the landfill edge and it is being controlled by installation of a localized gas collection system with a flare. There are also 45 passive gas venting pipes in the north landfill that are not monitored directly. Waste Reduction Goal Calculations In 2006-07 Orange County's state-calculated waste burial rate was 0.711 tons per capita., which is equivalent of a waste reduction rate of 47.7% per capita compared to the County's base year waste generation rate of 1.36 tons per capita in 1991-92. This is the County's highest calculated rate yet reached. Orange County is aware of at least one private in-County hauler that reported to us orally that they pick up about 1,400 tons of waste per year from Orange County residential customers and deliver it to the Durham [City] transfer station, yet no tonnage is noted in the annual state solid waste report as being delivered to the Durham Transfer Station from Orange County. We have notified Durham and the State Solid Waste Section of this 9
