Mitigation Measure HAZ-1 requires that a qualified consultant prepare a Soil Management Plan (SMP) to be used during earthwork and grading to identify soils that cannot be reused onsite and offsite disposal. Mitigation Measure HAZ-1 requires excavation of contaminated soils be completed pursuant to existing DTSC and RWQCB requirements, soils sampling to ensure all contaminated soils are removed, and that a certified hazardous waste hauler remove and transport all TPH impacted soil and other potentially hazardous materials per California Hazardous Waste Regulations to a landfill permitted by the state to accept hazardous materials. Excavated soil containing hazardous substances would be classified as a hazardous waste if they exhibit the characteristics of ignitability, corrosivity, reactivity, or toxicity (CCR, Title 22, Division 4.5, Chapter 11, Article 3). The SMP would detail hazardous materials excavation and disposal methods and requirements pursuant to the regulation of Title 8 of the California Code of Regulations (CaIOSHAj and Department of Toxic Substances Control (DTSC} that regulates the removal, transportation, and disposal of hazardous waste to protect human health and the environment. With implementation of Mitigation Measure HAZ-1 "Impacts related to hazards from contaminated soils would be less than significant (Draft Supplemental EIR at p. 5.6-22). Plans, Program and Policies: PPP HAZ-1: SCAOMD Rule 1403. Prior to issuance of demolition permits,, the Project applicant shall submit verification to the City Building and Safety Division that an asbestos survey has been conducted at all existing buildings located on the Project site. If asbestos is found, the Project applicant shall follow all procedural requirements and regulations of South Coast Air Quality Management District Rule 1403. Rule 1403 regulations require that the following actions be taken: notification of SCAQMD prior to construction activity, asbestos removal in accordance with prescribed procedures, placement of collected asbestos in leak -tight containers or wrapping, and proper disposal. PPP HAZ-2: Lead. Prior to issuance of demolition permits, the Project applicant shall submit verification to the City Building and Safety Division that a lead -based paint survey has been eri I I I I conducted at all existing buildings located on the Project site. If lead -based paint is found, the Project applicant shall follow all procedural requirements and regulations for proper removal and disposal of the lead -based paint. Cal -OSHA has established limits of exposure to lead contained in dusts and fumes. Specifically, CCR Title 8, Section 1532.1 provides for exposure limits, exposure monitoring, and respiratory protection, and mandates good working practices by workers exposed to lead. Mitigation Measures: Mitigation Measure HAZ-1: Prior to issuance of a grading permit, a Soil Management Plan (SMP) shall be prepared by a qualified hazardous materials consultant and shall detail procedures and protocols for excavation and disposal of onsilte hazardous materials, including: • Any subsurface materials exposed during construction activities that appear potentially contaminated, based on either visual observation or suspect odors, shall be segregated, stockpiled, and tested for potential contamination. If contamination is found to be present per the California Department of Toxic Substances Control (DTSC} Environmental Screening Levels (ESLs) for the applicable use, and cannot be reused on the Project site, it shall be transported
