The Wamer Redhill Mixed -Use Project CEQA Findings of Fact Impact Finding: The Project would not create a significant hazard to the public or the environment through reasonably foreseeable upset or accident conditions involving the release of hazardous materials into the environment (Draft EIR at p. 5.7-23). Facts in Support of Findings: Construction: Accidental Releases. While the routine use, storage, transport, and disposal of hazardous materials in accordance with applicable regulations during demolition, excavation, grading, and construction activities would not pose health risks or result in significant impacts; improper use, storage, transportation and disposal of hazardous materials and wastes could result in accidental spills or releases, posing health risks to workers, the public, and the environment. The use of Best Management Practices (BMPs) during construction implemented as part of a Stormwater Pollution Prevention Plan (SWPPP) as required by the National Pollution Discharge Elimination System General Construction Permit (and included as PPP WQ-1) would minimize potential adverse effects to workers, the public, and the environment to a less than significant level. Asbestos Containing Materials. Buildings on the Project site were constructed in 1979 and 1981 when many structures were constructed with what are now recognized as hazardous building materials, such as lead and asbestos. Demolition of these structures could result in the release of hazardous materials. However, asbestos abatement contractors must follow state regulations contained in California Code of Regulations Sections 1529, and 341.6 through 341.14 as implemented by SCAQMD Rule 1403 to ensure that asbestos removed during demolition or redevelopment of the existing buildings is transported and disposed of at an appropriate facility. The contractor and hauler of the material are required to file a Hazardous Waste Manifest which details the hauling of the material from the site and the disposal of it. Section 19827.5 of the California Health and Safety Code requires that local agencies not issue demolition permit until an applicant has demonstrated compliance with notification requirements under applicable federal regulations regarding hazardous air pollutants, including asbestos. These requirements are included as PPP HAZ-1 to ensure that the Project applicant submits verification to the City that the appropriate activities related to asbestos have occurred, which would reduce the potential of impacts related to asbestos to a less than significant level. Lead Based Materials. Lead -based materials may also be located within existing structures on the Project site. The lead exposure guidelines provided by the U.S. Department of Housing and Urban Development provide regulations related to the handling and disposal of lead -based products. Federal regulations to manage and control exposure to lead -based paint are described in Code of Federal Regulations Title 29, Section 1926.62, and state regulations related to lead are provided in the California Code of Regulations Title 8 Section 1532.1, as implemented by Cal -OSHA. These regulations cover the demolition, removal, cleanup, transportation, storage and disposal of lead -containing material. The regulations outline the permissible exposure limit, protective measures, monitoring and compliance to ensure the safety of construction workers exposed to lead -based materials. Cal/OSHA's Lead in Construction Standard requires project applicants to develop and implement a lead compliance plan when lead -based paint would be disturbed during construction or demolition activities. The plan must describe activities that could emit lead, methods for complying with the standard, safe work practices, and a plan to protect workers from exposure to lead during construction activities. In addition, Cal/OSHA requires 24- hour notification if more than 100 square feet of lead -based paint would be disturbed. These City of Santa Ana 17 May 2020
