21 <br /> 1 Vice-Chair Hamilton asked about the relationship between density issues and capacity. <br /> 2 She asked how that affects development versus extending the system outward. <br /> 3 Shannan Campbell said she would rather have one acre in town that is already on the <br /> 4 sewer line be developed than run a line a mile out. She said that inflow and infiltration issues are <br /> 5 from old pipes, leaky pipes, connections into sewer lines from stormwater runoff. She said that <br /> 6 the fewer lines they have, the better they can maintain the lines. <br /> 7 Vice-Chair Hamilton asked if developing something in town requires replaced pipes. <br /> 8 Matt Efird said it goes back to a function of the priority areas. He said that if the deficit was <br /> 9 treatment plant capacity it would not matter where the development occurred but because it is <br /> 10 related to pinch points in the flow, it matters. <br /> 11 Shannan Campbell said that water pressure is an issue in town. She said adding density <br /> 12 in town is much more feasible because multi-family units often require sprinklers, and this is <br /> 13 harder to do farther out due to pressure. <br /> 14 <br /> 15 4. Plans for Fairview Park — Update on Landfill and Project Planning & Connection to <br /> 16 Fairview Activate Plan <br /> 17 <br /> 18 The Fairview Landfill is a closed, pre-regulatory landfill (PRLF) that was owned and operated by <br /> 19 the Town of Hillsborough from the early 1940's to approximately 1975. PRLF's include any land <br /> 20 area that was used for municipal solid waste disposal prior to January 1, 1983. The landfill is an <br /> 21 unlined facility that encompasses approximately 21 acres located in the Fairview Park <br /> 22 neighborhood, north of Torain Street and west of North Carolina Highway 86. Based on the most <br /> 23 recent delineation, approximately 17.7 acres of the waste disposal area is located on property <br /> 24 owned by Orange County and 3.3 acres of the waste area is located on property owned by the <br /> 25 Town of Hillsborough. <br /> 26 <br /> 27 PRLF's across North Carolina were unlined and unregulated receiving facilities and therefore <br /> 28 could contain hazardous waste, medical waste, and/or asbestos-containing materials. There was <br /> 29 no prior record keeping performed for the Fairview facility as to quantity and types of waste, <br /> 30 however studies have shown a mixture of white goods, glass, metal, tires, construction debris, <br /> 31 and automotive parts throughout the site. Contaminated soils, exposed hazardous materials, <br /> 32 contaminated groundwater, hazardous and/or explosive vapors are all typical risks associated <br /> 33 with PRLF's, therefore a complete assessment was necessary to ensure the safety of our <br /> 34 Hillsborough community. <br /> 35 <br /> 36 In 2017, Orange County began working with the Pre-Regulatory Landfill Program at the North <br /> 37 Carolina Department of Environmental Quality (NCDEQ) to conduct a remedial investigation of <br /> 38 the Fairview Landfill. Studies conducted through this program are fully reimbursable to the local <br /> 39 government by NCDEQ, so Orange County contracted with S&ME Inc., an environmental <br /> 40 consulting firm from Raleigh, NC, to conduct this investigation on their behalf. The data collection <br /> 41 process has been a multi-year one, but the investigation is nearing completion. A recent <br /> 42 Hillsborough Landfill (NONCD0000483) Remedial Investigation Work Summary (included in <br /> 43 Attachment 4a)was produced by Zi-giang Chen, an Environmental Engineer at NCDEQ, is all the <br /> 44 work that has been completed thus far. <br /> 45 <br /> 46 The Boards can discuss issues related to this item as necessary, and staff will be available at the <br /> 47 meeting. <br /> 48 <br />
