.10 Pacific Gaswd <br /> Elecbic cmPs . <br /> December 21, 2011 <br /> San Joaquin County, <br /> Pacific Gas and Electric Company (PG&E) is planning to conduct some natural gas <br /> pipeline integrity testing in your town. The testing is known as a"close interval survey." <br /> The pipeline has been in service for many years, and has continued to provide safe and <br /> reliable service to your community. PG&E is required by Federal and State regulations <br /> to perform this testing. <br /> The testing will be performed by our contractor, Mears Cpg, under PG&E supervision. <br /> The testing involves placing a probe in contact with the ground surface,there is no <br /> excavating involved, and taking readings of the corrosion protection on the pipe, every <br /> ten feet along the pipeline. If the surface/cover above the pipe is soil, including grass, <br /> dirt, etc., the test reading can be taken directly, without drilling holes. However, if there <br /> is a hard, insulating surface such as asphalt or concrete, a 1/2 inch diameter hole must be <br /> drilled through the thickness of the asphalt or concrete to reach the soil or base rock <br /> surface. If drilling is required, the following occur: the test measurement is recorded after <br /> drilling, the data quality is verified, and the hole is plugged with an approved plug and <br /> crack sealer(See attached documents). This process provides a waterproof repair for the <br /> small hole. If a specific material and process is requested, in lieu of the enclosed <br /> procedure to fill and patch the holes,please note that condition on the permit and provide, <br /> in writing, the specification. Underground Service Alert tickets are called in for this <br /> work. <br /> There is also a generic mobile traffic control plan that is enclosed that has been assigned <br /> to your roadways. Please notify me if a site specific plan is required for any of the <br /> proposed work areas. The scope of work is temporary &mobile. <br /> Land Owner Notifications are being sent to all private property owners near the pipeline <br /> to inform them of the local street activity. In some cases, door hangers are hung by the <br /> foreman ahead of time when the survey must encroach upon private property to gain <br /> access to the pipeline easement. <br /> There are several miles of pipeline that require this testing in your area and we are <br /> scheduling this test approximately during the month of February. Work may also occur <br /> on Saturdays. In the event that you have any questions,please feel free to contact myself <br /> at(925) 323-0904 or my alternates, Eric Tsai at(925) 974-4285 and Jeremy Locquiao <br /> (925) 974 - 4090. <br /> Thank you for your time, <br /> Aj sha Pullin <br /> Pacific Gas and Electric Company <br /> Permit Coordinator <br /> (925) 323-0904 <br />
