El 71 Noise The proposed project expansion includes the processing of concrete and debris as well as wood grindings. An evaluation of the noise that was.analyzed in ER -93-0001 and what is being proposed was addressed in a Supplemental Noise Study (SNS) submitted by the applicant on June 20, 2011. It was noted in both documents that the proposed project site is located within a reclaimed excavated pit that is 30-40 feet in depth which largely makes up the current 39.2 acres. The nearest residence is 840 feet northeast of the project site. The existing facility is enclosed down in the former gravel pit, where ER -93-001 and the Supplemental Noise Study concluded that there were no potentially significant impacts from the current project or the proposed expansion project and mitigation was not required. Additionally, as a Condition of Approval all outdoor processing activity shall not begin before 6:00 am and will not operate after 10:00 pm. These activities Include construction and demolition of inert debris (CDI) and the processing of wood waste grindings. San Joaquin County Multi -Species Habitat Conservation and Open Space Plan (SJMSCP) The Council of Governments was sent a referral on August 19, 2011 and responded in a memo dated August 29, 2011. The memo states that this project is subject to the San Joaquin County Multi -Species Habitat Conservation and Open Space Plan (SJMSCP) and is located within the unmapped land use area. Per requirements of the SJMSCP, unmapped projects are subject to case-by-case review. San Joaquin County is a signatory to the SJMSCP. Participation in the plan satisfies requirements of both the state and federal endangered species acts, and ensures that the impacts are mitigated below a level of significance in compliance with the California Environmental Quality Act. Although participation in the SJMSCP is voluntary, if the applicant chooses not to participate, the applicant will be required to provide alternative mitigation in an amount and kind equal to that provided in the SJMSCP. The applicant has indicated they will participate in the program and this will reduce any potentially significant impacts to both the state and federal endangered species to less than significant. The project site boundaries fall within the comprehensive airport land use plan for Tracy Municipal Airport (TMA). The nearest runway of the TMA is approximately one mile west of the existing project site. This application is to expand the existing Materials Recovery Facility and a portion of the project falls within the Traffic Pattern Zone for the TMA. In a letter dated March 28, 2011 from the Council of Governments acting as the Airport Land Use Commission (ALUC), it determined that the Initial Study did not provide enough information to conclude if the proposed expansion would not create a safety hazard or is not in conflict with the 2009 Airport Land Use Compability Plan for TMA. A revised initial study was prepared on October 7, 2011 and recirculated discussing compability with the 2009 Airport Land Use Plan. As required the project sponsor shall abide by the applicable Airport Land Use Plan for Tracy Municipal Airport and the Federal Airport Administration Advisory Circular No: 150/5200-33B, Hazardous Wildlife Attractants On or Near Airports. Therefore the proposed expansion project will have less than a significant impact on airport imaginary surfaces. In addition, the March 28, 2011 letter also states that the uses associated with the proposed expansion are compatible as long as the trash transfer is enclosed and does not handle or store putrescible waste. Currently the applicant conducts the majority of its activities indoors at the Material recovery building consisting of approximately 57,200 square feet, including the tipping, processing and transfer of municipal solid waste and non - recyclable residues for land filling. As part of the compliance with 2009 Airport Land Use Plan the ALUC requests that the following uses not be allowed as conditions of approval: 1. New land uses that may cause visual, electronic, or increased bird strike hazards to aircraft in flight shall not be permitted within any airport's influence area; San Joaquin County PA-0800005\Tracy Material Recovery Community Development .
