Imported Fill Material (2001 or most recent version) as outlined in the Regional Water Board -Approved Response Plan. Fill testing shall be performed by a qualified environmental professional and demonstrated to meet the appropriate threshold criteria. The results of the testing shall be submitted to the Regional Water Board for review and approval prior to importing of fill material and surcharging materials to the project site or re -use of material generated from the project site. The contractor shall prepare a Waste Disposal and Hazardous Materials Transportation Plan, which shall be submitted to the City prior to any demolition and construction activities. This plan shall describe the analytical methods for characterizing wastes and the handling methods required to minimize the potential for exposure, and shall establish procedures for the safe storage of contaminated materials and stockpiling of soils. The required disposal method for contaminated materials, the approved disposal site, and specific routes used for transport of wastes to and from the project site shall be indicated. • Hazardous materials and wastes generated during demolition, grading, and trenching activities, shall be removed, managed, and disposed of in accordance with applicable regulations. The requirements of the Response Plan listed above shall be performed during all intrusive construction activities performed for the proposed project that involve work below the current ground surface elevation, including after the completion of soil remediation activities proposed in the Response Plan. Finding: Implementation of Mitigation Measure HAZ-1 would reduce the project - related impact to accidental release of hazardous materials and/or the disturbance and reuse of soil potentially impacted with hazardous materials to a less -than -significant level. Facts in Supaort of Finding: This mitigation measure appropriately identifies the process for preparation of a Response Plan, the requirements for the activities that shall be included, and the requirement that the Response Plan be reviewed and approved by the Regional Water Board. Impact HAZ-2: Construction of the proposed project and the project variant could result in accidental releases of hazardous building materials that could result in impacts to construction workers, the public, and/or the environment. Mitigation HAZ-2: Prior to demolition activities, a Hazardous Building Materials Survey (HBMS) shall be performed by an appropriately certified environmental professional which shall identify whether ACMs, PCBs, LBP, or other hazardous materials are present in the existing structures on the project site. Specification for the abatement and disposal of identified hazardous materials in accordance with applicable regulations shall be prepared by an appropriately certified environmental professional. The HBMS and abatement specifications shall be submitted to and approved by the City prior to the start of abatement activities. Abatement activities shall be performed by appropriately certified personnel in accordance with all applicable laws and regulations and documented in a Closeout Report prepared by an environmental professional who shall oversee the abatement activities. The Closeout Report shall be submitted to the City for review and approval prior to the issuance of a demolition permit. ATFY/RESO.0035/CC RESO CERTIFYING FINAL EIR-1548 MAPLE RESO.
