.. o · Each TDSR site will eventually be emptied of all material and be restored to its previous condition and use. TAG will remove and dispose of all mixed debris, construction and demolition (C & D) debris, and debris residue to approved landfills. Quality assurance inspectors will monitor all closeout and disposal activities to ensure contract compliance. Additional measure required by local, state, and federal agencies will be adhered based on the nature of the staging and reduction operation. · All sites will be properly remediated. TAG will establish baseline data collection and strict site operation procedures will be followed to ensure proper restoration. · The basic closeout steps are to remove all debris from the site; conduct and environmental audit or assessment; develop a remediation or restoration plan approved by the appropriate environmental agency; execute the plan; get acceptance from the landowner; and terminate lease payments, if applicable. The key to timely closeout of the mission is the efficient scheduling of the above activities for multiple sites. Therefore critical path scheduling of all activities as far in advance as possible will minimize down time between steps. . Environmental Restoration: Stockpiled debris will be a mix of woody vegetation, construction materials, household items, and yard waste. HHW and medical waste will be segregated and removed prior to stockpiling. Activities at the debris disposal site will include anyone or a combination of the following activities: stockpiling, sorting, recycling, incineration, grinding, and chipping. Incineration is done in air curtain pits and generally only woody debris is incinerated; however, the efficiency of the incineration and the quality of incineration material is highly variable. Contamination may occur from petroleum spills at staging and reduction sites or runoff from the debris piles, incineration sites, and ash piles. · Site Remediation: During the debris removal process and after the material has been removed from each debris site, environmental monitoring will be need to close each of the sites. This is to ensure that no long-term environmental contamination is left on the site. The monitoring should be done on three different media: ash, soil, and groundwater. · The monitoring of ash should consist of chemical testing to determine the suitability of the material for land-filling. · Monitoring of the soils should be by portable methods to determine if any of the soils are contaminated by volatile hydrocarbons. TAG will do this if it determined that hazardous material, such as oil or diesel fuel was spilled on the site. This phase of the monitoring should be done after the stockpiles are removed from the site. . The monitoring of the groundwater should be done on selected sites to determine the probable effects of rainfall leaching through either the ash areas or the stockpile areas. · TAG Grinding Services, Inc. considers the following requirements to closeout a temporary staging and reduction site(s): ./' Coordinate with local, state, and federal officials regarding requirements and support for implementation of a site remediation. ./' Establish a testing and monitoring program. TAG will be responsible for environmental restoration of both public and leased sites. TAG will also remove all debris from sites for final disposal at landfills prior to closure. ./' Reference appropriate and applicable environmental regulations. ./' Prioritize site closures. ./' Schedule closeout activities. ./' Determine separate protocols for air, water, and soil testing. ./' Develop cost estimates. ./' Develop decision criteria for certifying closure based on limited baseline information. ./' Meet with approving authority to review and evaluate closure activities, progress, and completion. o o
