State or Cainomia Caiiromia EmAronrt ental Protection Aa ncv Deoartment of Toxic Substances Control procedures are enforceable and made a condition of project approval and will ensure that impacts to the environment will be less than significant. As a result, DTSC finds that the project is exempt from further environmental review under CEQA. Table 2 shows the estimated emissions produced during the project duration. The project is under the jurisdiction of the San Joaquin Unified Air Pollution Control District, which utilizes the URBEMIS 2007 emissions model,similar to the South Coast Air Quality Management District model used to calculate greenhouse gas emissions on the next page. Due to the use to Tier 3 and Tier 4 equipment,the project is expected to have a less than cumulatively significant impact on air quality. This project will have a 30%reduction in greenhouse gas emissions as compared to an identical project and equipment using the URBEMIS 2007 model comparing 2008 to 2012 equipment and emissions standards. The planned excavation area is approximately 0.73 acres. Excavation areas will be controlled with physical barriers(e.g., perimeter fencing with tarps), soil wetting and air monitoring(at property perimeter and work area)to avoid or control dust generation. Water will be used to control any fugitive dust from blowing onto other properties. In times of high wind conditions(e.g.,wind speed in excess of 25 miles per hour), all excavation activities will cease, and the Site will be stabilized. These dust control measures are consistent with the rules and best management practice requirements of the San Joaquin Valley Air Pollution Control District. Construction Control Measures: Impacted soil will be removed with a loader and excavator, or similar equipment. As soil is excavated, it will be temporarily stored in staging areas onsite until off-site disposal transportation and disposal is available. At the staging areas, all excavated soils will be placed on an impermeable barrier and covered with tarps or other proper materials to prevent any run-on and/or dust generation. If significant rainfall is anticipated,the staging areas will be bermed to contain any run-off. During non-excavation hours, excavated soil stockpiles will be covered with plastic sheeting or other proper materials. Alternatively, excavated soils may be placed in covered roll-off bins or drums,or may be loaded directly onto transportation trucks. The temporary onsite storage of excavated soil wastes will be secured and properly labeled with hazardous waste signs until offsite transportation and disposal are ready for loading. In no case,will the waste storage be longer than 90 days after its generation. Waste Management(Treatment and Disposal)Measures: Prior to the start of excavation, all health and safety, noise and dust control equipment and materials will be prepared and positioned for immediate use, as necessary. It is anticipated that the majority of materials will be directly loaded onto trucks. If it is necessary to stockpile soil, 10-mil plastic or plywood will be placed beneath the stockpiles. All stockpiled soil will be covered with 10-mil plastic sheeting secured with sandbags or other anchoring devices. Soils deemed hazardous will be transported to a licensed Class 1 landfill. Non-hazardous soils will be transported to an approved facility or Class 3 landfill(Allied Waste Forward Landfill). Transportation Measures:All hazardous soils will be shipped by a registered hazardous waste hauler under manifests or proper.shipping documents to an approved Class 1 landfill(Waste Management Kettleman Hills Facility). All hazardous and non.-hazardous waste soils will be shipped in tarped trucks. All vehicles will be decontaminated and inspected prior to leaving the work area to ensure that their loads are secure and contaminated soil is not tracked off-site. Transportation of materials removed from the site will be on pre-planned and authorized routes in accordance with the Transportation Plan, minimizing any potential impact on the local neighborhood. Trucks will be staged to avoid impacts on the local streets and timed to avoid rush traffic hours. Approximately 680 truck trips(round trip)will be used to transport contaminated soils from the site and bring fill material to the site. The,do not appear to be any sensitive receptors along the route from the Site to Highway 99,which is less than a mile east of the site. Instead of heading eastbound on Kettlemah Lane to Highway 99,trucks will travel another mile southbound on Stockton Street to avoid the Lodi Academy School. 2 DTSC 1332 VCP NOE June 21,2012 Office of Planning&Environmental Analysis
