8.A. - Page 81 Section 4: Evaluation of Environmental Impacts will not exempt any future development from the City's programs to control and safely dispose of hazardous materials and wastes or to reduce the volume of wastes requiring landfill disposal. Thus, no impact will result. With regard to construction, because the majority of Redwood City is developed, housing development pursuant to Housing Element policy will likely involve demolition of existing structures. BAAQMD Regulation 11 -2 -401.3 requires that for every renovation involving the removal of 100 square feet /linear foot or greater of Regulated Asbestos Containing Material (RACM), and for every demolition, BAAQMD must be notified. This rule is generally designed to protect uses and persons adjacent to demolition or renovation activity from exposure to asbestos emissions. All future housing developments will be subject to the City's standard review process for evaluation of hazards. Considering implementation of existing policies and standards, impacts associated with asbestos hazards will be less than significant. Exposure of construction workers to lead -based paint during demolition activities is also of concern, similar to exposure to asbestos. Exposure of surrounding land uses to lead from demolition activities is generally not a concern because demolition activities do not result in appreciable emissions of lead. If lead contamination exists on future housing sites, 8 CCR Section 1532.1 (California Construction Safety Orders for Lead) is applicable to the demolition of all existing structures requiring exposure assessment and compliance measures to keep worker exposure below action levels. Development projects will also be subject to Title 22 requirements for the disposal of solid waste contaminated with excessive levels of lead. Impacts due to lead exposure and contamination will be less than significant with adherence to existing regulations. c) No Impact. No specific new development is associated with the proposed Housing Element. Since a large number of Opportunity Sites are located throughout Redwood City, schools are likely to be located within one quarter mile. However, future residential development that may be facilitated by this Housing Element update will not generate hazardous air emissions and will not involve the handling of any acutely hazardous substances or wastes. Thus, the updated Housing Element will not result in impacts related to the presence of any hazardous materials or emissions within one quarter mile of a school. No impact will occur. d) Less than Significant Impact. According to the databases maintained as the Cortese List, none of the Opportunity Sites identified in the Housing Element update are identified on the Department of Toxic Substances Control (DTSC) Hazardous Waste and Substances Site List or the State Water Resources Control Board (SWRCB) list of cleanup sites. However, the General Plan EIR identifies 66 active and 146 inactive leaking underground storage tanks (LUST). Current regulations require double -wall construction and leak monitoring equipment for underground storage tanks which will reduce the number of releases in the future. The General Plan EIR evaluated hazardous materials impacts and determined all potential impacts as less than significant. The Housing Element is in compliance with the adopted General Plan. Any future development will be subject to the City's standard review that will include identification of any contaminated site possibly not already identified and implementation of appropriate cleanup and disposal procedures; therefore, less than significant impacts related to contaminated sites will occur. This is consistent with the policies of the General Plan Public Safety Element. Impacts will be less than significant. 23 California Environmental Protection Agency.
