Pacific Gas and <br /> November 8, 2013 Electric Cofnpany`" <br /> San Joaquin County, <br /> PG&E is planning to conduct some natural gas pipeline integrity testing in your town on <br /> an existing gas pipeline that has been in service for many years, and has continued to <br /> provide safe and reliable service to your community. The testing is known as a"close <br /> interval survey." PG&E is required by Federal and State regulations to perform this <br /> testing. <br /> The testing will be performed by PG&E's contractor, Mears Group, under PG&E <br /> supervision. The scope of this work is temporary & mobile and involves placing a probe <br /> in contact with the ground surface (no excavating involved) and taking readings of the <br /> corrosion protection on the pipe, every ten feet along the pipeline. If the surface/cover <br /> above the pipe is soil, including grass, dirt, etc., the test reading can be taken directly, <br /> without drilling holes. However, if there is a hard, insulating surface such as asphalt or <br /> concrete, a 1/2 inch diameter hole must be drilled through the thickness of the asphalt or <br /> concrete to reach the soil or base rock surface. If drilling is required, the following will <br /> occur: the test measurement is recorded after drilling,the data quality is verified, and the <br /> hole is plugged with an approved plug and crack sealer. This process provides a <br /> waterproof repair for the small hole. If a specific material and process is requested to fill <br /> and patch the holes, please note that condition on the permit and provide, in writing, the <br /> specification. Underground Service Alert tickets are called in for this work. <br /> Generic and/or site specific traffic control plans will be submitted for your review and <br /> approval. <br /> Land Owner Notifications are being sent to all private property owners near the pipeline <br /> (within a 250' radius) to inform them of the local street activity. In some cases, door <br /> hangers are hung by the foreman ahead of time when the survey must encroach upon <br /> private property to gain access to the pipeline easement. <br /> There are several miles of pipeline that require this testing throughout PG&E's service <br /> territory, so this "survey" work will be scheduled and performed shortly after you are <br /> able to issue an approved permit. <br /> If you have any questions, please feel free to contact me. Thank you, <br /> Chris Jennings <br /> GTS/Pacific Gas and Electric Company <br /> Permit Coordinator <br /> (925) 324-5219 <br />
