! <br />! <br />! <br />i <br /> <br />1 <br /> <br /> Overall, erosion and sediment control features need <br />improvement to properly manage surface waters. The <br />headwaters of Jones Creek are piped beneath the landfill. <br />This presents a challenge Of Iong-term monitoring and <br />handling of these waters in the event of contamination. <br />There are no ground water monitoring wells at the site. A <br />ground water monitoring system will need to be installed by <br />July 1, 1991.- <br /> <br /> Soils in the area are mostly sandy with cobbles and <br />boulders within the drainageways. Above the drainageways, <br />residual soils overlay bedrock. Existing soil excavations <br />on-site range from 10 to 15 feet in depth. <br /> <br /> Based on the proposed FY 89-90 budget, total costs for <br />solid waste collection and disposal is estimated at <br />$553,116. Based on an annual tonnage of about 55,750 tons, <br />the cost per ton is estimated at $9.92. The City has 186 <br />dumpsters located throughout the City with pick-up occurring <br />at various times during the week. <br /> <br /> The existing fill area, due to new regulatory <br />requirements, will have to cease operation on June 30, 1992. <br />Closure will have to be accomplished by the end of 1992. An <br />updated closure plan, in compliance with the new <br />regulations, needs to be submitted by December 21, 1990. <br />Landfilling beginning July 1, 1992 will have to be in a new <br />facility fully compliant with the new regulations. Post- <br />closure activities (water monitoring, leachate management, <br />site maintenance) must continue for 10 years; however, <br />proposed federal regulations will increase the post-closure <br />period to 30 years. <br /> <br /> In utilizing the site until July 1, 1992, it will be <br />necessary to fill atop the existing fill to achieve final <br />grades more conducive to allowing drainage of surface waters <br />and to meet new regulatory requirements. At present, the <br />top 'surface of the existing fill is relatively flat, not <br />allowing ready drainage of surface water. Infiltration of <br />surface water is a classic contributor to leachate <br />generation. Based on waste load quantities, the <br />Martinsville waste stream will account for only about two- <br />thirds of the volume needed to fill and slope the top of the <br />existing fill to meet new regulatory requirements. <br /> <br />E.1.3 <br /> <br />HENRY COUNTY SANITARY LANDFILL <br /> <br /> The types of equipment observed at the landfill have <br />been appropriate. However, the number of pieces of <br />equipment has been inadequate. The types and numbers of <br />equipment seems variable. There has been only one person <br />operating the site each time we observed operations. This <br /> <br /> <br />
