2.0 ENVIRONMENTAL CHECKLIST pipeline. Measures HM-1 and HM-4 would mitigate the inadvertent misuse of hazardous materials. d) The proposed pipelines and associated facilities would be in areas zoned as commercial, recreation, industrial, open space, public and semi-public and residents. Based on the results of an environmental database search, there are no known hazardous naterial contaminated sites itn the immediate Project area that may affect the Project. The RWQCB shall require contractors to prepare and submit a Health and Safety Plan, with specific provisions to protect both workers and the public during construction (see Measure HM-1), and shall revise the WPCP's Hazardous Materials Business Plan, with protection measures for all other times (see Measure HM-4). The implementation of these measures, if contamination is encountered, would reduce potential impacts to ales-than-significant level. e,f) The Oakland International Airport is located northeast of the WPCP. However, as discussed in the Project Description, the Project consists of underground pipelines and one small building and is not located on the airport property. Therefore, the Project would not interfere with any airport operations. g) The pipeline and associated facilities would not be expected to interfere with an emergency response plan or emergency evacuation plan. Please also refer to the Traffic section for a discussion of emergency access during construction. h) The Project is within an urban setting and would not expose people to wildfire risks; therefore, no impacts are anticipated. MITIGATION MEASURES Measure HM-1: Prepare a Health and Safety Plan. Prior to issuance of grading permits, the City shall require the contractor to prepare a Health and Safety Plan that includes aProject- specific contingency plan for hazardous materials and waste operations before construction activities could begin. The Health and Safety Plan shall be applicable to all construction activities, and shall establish policies and procedures to protect workers and public from potential hazards. The plan shall be prepared according to federal and California OSHA regulations for hazardous materials Health and Safety Plans. Elements of the plan shall include, but not be Iirnited to, the following: A discussion of hazardous materials management, including delineation of hazardous material storage areas, access and egress routes, waterways, emergency assembly areas, temporary hazardous waste storage areas; Notification and documentation procedures; and Spill control and countermeasures, including employee spill prevention/responsetraming. Measure HM-2: Consultation with Utilities. Prior to final design, the proposed pipeline alignment shall be provided to all utilities and pipelines that may be within the construction right- of-way to verify no conflict between the proposed alignment and existing utilities. Verification of no utility conflict shall be provided by the utilities lea the City. ~ Database search conducted by BBL environmental Information (BBL) on October 15, 2004 (BBL, 2004).
