Gather baseline data from the site to document the state of the land before debris is deposited. The attached Investigation of Property Suitability form can be used to assess potential sites. The following action items are recommended to compile baseline information: a. Photograph the site – Digital photos should be taken to capture the state of the site before debris reduction activities begin. Photos should be updated periodically throughout the project to document the progression of the site. b. Record physical features – Records should be kept detailing the physical layout and features of the site. Items such as existing structures, fences, landscaping, etc., should be documented in detail. c. Historical evaluation – The past use of the site area should be researched and documented. Issues relating to historical or archeological significance of the site should be cleared with the state historical preservation agency. d. Sample soil and water – If possible and deemed necessary, soil, and groundwater samples will be taken before debris reduction activities commence. Samples will help ensure the site is returned to its original state. Typically, soil and groundwater samples should be analyzed for total Resource Conservation and Recovery Act (RCRA) metals, volatile organic compounds, and semi-volatile organic compounds using approved U.S. Environmental Protection Agency (EPA) methods 2. Acquire the necessary approvals for the site – TDMSs will require approval from the Alameda County Environmental Health Department serving as the Local Enforcement Agency (LEA) for the County. Use the attached TDMS Information Form to record site information. Coordinate with local and state authorities for any additional approvals 3. Set up the TDMS a. Determine the layout for the site. See attached example. b. Determine traffic patterns for trucks to safely enter and exit the site. c. Set up monitor tower(s) 4. Begin TDMS operations a. Establish debris staging and reduction operations b. Conduct disposal monitoring 5. Begin environmental monitoring program of TDMS 6. Open additional TDMSs as necessary 7. Complete the disposal of reduced debris 8. Close out and remediate TDMSs
