Health and Safety Plan 17 West Washington Street, Stockton, California 95202 461803 Page 3 4.1 Specific Procedures 1. Obtain and/or develop an accurate location plan for the target area where subsurface work will be conducted. Overlay this plan with the expected locations of where subsurface work will be conducted by AEI and/or their contractors or sub-contractors. 2. Arrange for approved public service locator to visit site and mark out utilities to property line. 3. Request site specific underground service information from the owner and/or occupier of the site and include on location plan. 4. You MUST conduct a site walk-over and complete the Subsurface Clearance Form included as Appendix C to this HASP, and Table 5 above. The main intent of this form is to identify above ground identifiers (e.g., the existence of an above ground gas valves, water outlets, telecommunications access point, patches, soil depressions, etc.) which may indicate the potential existence of subsurface issues. Ideally, the completion of this form should be conducted in conjunction with the efforts of the private locator or prior to their arrival on site. This would assist the locator in focusing their efforts on areas where potential subsurface issues may exist. 5. Ensure that identified utilities are traced/marked by the locator/owner/occupier, using the following as a minimum: x Where practicable, trace and mark/label all incoming services; x Agree on all locations for potential intrusive works; clear these with the Client Contact; and mark/identify locations on the ground and on the site plan; x Provide private locator with plans of potential intrusive work; x Ensure that the locator marks all detected services and those featured on location plans to within a 10 foot (3 meter) radius of EACH location where intrusive work will occur, and adhere to “Restricted Areas” directives in AEI’s SCC Policy (Appendix C.) x Ensure locator surveys the proposed work site to find other potential service utilities, as applicable. x Ensure that any intrusive works are located a minimum of 10 feet (3 m) horizontally from any overhead electric cable supported on wooden poles, or 50 feet (15 m) horizontally in the case of those supported on metal poles/towers. Where this cannot be achieved, contact the relevant electricity provider for guidance as well as the SVP in Charge, Director of H&S, and the SSO. 6. Where any doubt exists over a service which cannot be traced, request a site visit from the appropriate utility provider or abandon locations in the immediate area and contact the PM or SVP. 7. Following the completion of the public/private surveys and other collected information (i.e., site walk-over and information provided by the Client Contact/site representative) but prior to commencing the intrusive investigation, review and verify the results of all information. Ensure that on-site contact information is available and/or that the location(s) of any isolators/stop-cocks/values are known and/or are marked/indicated on the location plans or otherwise highlighted, as applicable. 8. Locations which have been marked on the ground and have been cleared by the private locator are considered FIXED. Conducting intrusive operations outside the cleared area / radius is PROHIBITED.
