Cities of Dublin and Pleasanton | Disaster Debris Management Plan | 2022 29  Parks  Large parking lot  ROW  Jurisdiction owned property  Private property Environmental permits and land-use variances may be required during removal operations for TDMS(s). Several agencies may be involved in issuing permits and granting land-use approvals. Permits may include:  Waste processing and recycling operations permit  Temporary land-use permits  Land-use variances  Traffic circulation strategies  Air quality permits  Water quality permits  HHW permits  Fire department permits After a review of the availability and suitability of a TDMS, site preparation can begin. As part of the preparation, baseline data should be gathered from the site to document the state of the land before debris is deposited. The following actions support compiling the baseline:  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.  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.  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 Office of Historic Preservation.  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 State and U.S. Environmental Protection Agency (EPA) methods.  Site approval – TDMSs will require approval from the Alameda County Environmental Health Department serving as the Local Enforcement Agency (LEA) for the County. Once debris is collected from the public ROW, it is transported to a TDMS where it is segregated and reduced. Reduction methods include: Chipping and Grinding – Using this method, vegetative debris is chipped or ground and typically results in a reduction ratio of up to 4:1. Factors such as debris composition, weather, site conditions,
