RFP No. '16-043 A2 — 1,lazardous Materials Surveys d. Understanding of Need Buildings planned for renovation or demolition require an asbestos containing material (ACM) survey In accordance with the local SCAQMD Rule '1403 requirements, and the EPA National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations for asbestos. A lead based paint (LBP) survey is performed to evaluate the applicability of the lead in construction standard Title 8 California Code of Regulations Section 1532.1 which applies to all construction work including renovation or demolition activities where an employee may be occupationally exposed to lead. The LBP survey is also performed to evaluate building materials to determine their specific disposal requirements. Other hazardous materials which may be present within structures and which may be affected by renovations or demolition activities must also be Inventoried. These materials require proper clean up, handling, and disposal in accordance with Universal Waste Rules. Methodology and our Anticipated Approach for Hazardous Material Surveying: Our extensive experience in providing hazardous material surveys has benefitted our current and past clients. Through that experience, Ninyo & Moore has developed an efficient approach to this work. Our approach is described as follows. Prior to conducting work at all project sites, Ninyo & Moore will review the building drawings and any available ACM, LBP, and hazardous materials survey reports in order to develop a specific asbestos and lead sampling work plan, Specific known information about the project structures will also be obtained by meetings with client (or others). If previous asbestos survey reports are older than five years, an updated survey report is required by and will be prepared in accordance with SCAQMD requirements. Existing survey documentation and laboratory analysis related to ACMs will be reviewed for compliance with the requirements outlined in SCAQMD Rule 1403 and the requirements and sampling protocol outlined by the California Division of Occupational Safety and Health and NESHAP. Lead inspections will be performed by X -Ray fluorescence (XRF) analysis and paint chip sampling analysis, as needed. Lead surveys will be performed in accordance with the California Department of Public Health and HUD lead inspection requirements. At the project sites found to have existing survey information that is inconclusive or inadequate, Ninyo & Moore will sample building materials suspected to be hazardous that will be impacted by renovation or demolition activities. We use field forms specifically designed for conducting hazardous materials surveys, and will coordinate field activities so that AGM, LBP, and other hazardous materials surveys can be conducted simultaneously within each project site to be surveyed. Other hazardous materials may include mercury, polychlorinated biphenyls (PCBs), refrigerants, chemicals, solvents, heating oils, hydraulic fluids, tritium -containing exit signs, etc. We understand that buildings may be occupied at the time of our surveys. For this reason, it is important to: 1) collect samples only when occupants are not present in the areas to be sampled; and 2) use non-destructive sampling techniques, wherever possible, to minimize the impact to the areas sampled. For building demolition projects, or when requested, Ninyo & Moore will sample inaccessible areas. His typically requires some level of destruction. We have conducted hazardous building materials surveys at numerous occupied facilities, and thoroughly understand the procedures that will minimize disruption to operations. Field work is performed in accordance with a site-specific health and safety plan prepared by Ninyo & Moore's Certififed Industrial Hygienist. The field team consists of a CAC or CSST performing the asbestos survey, and a CDPH LRC I/A or ST performing the LBP surveys. All samples are collected, managed, and transported in accordance with relevant local, state, and Ninyo & Moore I City of Santa Ani - (A2) Hazardous Material Surveys 1 05.00713 A2 I June 5, 2018
