As part of our Pipeline Integrity Management Program, we will replace approximately 77 miles of 95 miles of high pressure transmission pipeline between Westminster, Colo., and the Wyoming border. The additional pipe will be abandoned or switched to distribution uses. This work will ensure safe, reliable service to our current and new customers along the Front Range.
Work in Larimer and Weld counties started in 2012 and is expected to continue through 2015. Work in Boulder County is expected to start in 2015 and continue through 2016.
This project is one of a package of pipeline integrity management programs and projects that are funded by the Pipeline System Integrity Adjustment (PSIA) rider that appears as a separate line item on Xcel Energy's natural gas customers' bills. We anticipate that in 2014, on a monthly bill, it will cost an average residential customer using 62 therms a month 36 cents, and the average small business customer using 270 therms a month $1.56.
We have finished asphalt restoration, and are finishing painting roads and final construction clean-up. We are in the process of inspecting the new pipeline before putting it into full operation.
Southern Larimer County
Currently we are installing new natural gas pipeline using directional boring at the Little Thompson River and Pheasant Run. We are installing new natural gas pipeline by using open trenching along Sundown Drive and along Larimer County Road 10E. We are getting ready to connect segments of pipeline together and to new and existing valve stations.
Currently the northbound lane of Larimer County Road 21 is closed between Larimer County Road 4 to just north of Larimer County Road 6. Larimer County Road 21 is open to southbound traffic only in this area. No other road or lane closures are planned for any other work currently in progress. We expect to open Larimer County Road 21 to normal traffic flow by the end of October 2014.
