20" Southeast Metro Project (2021)

Project Overview

1. Permitting and Environmental Review Requirements. Much of the existing pipeline is located in a

densely populated residential area. Installation of the new pipeline will involve significant permitting

reviews with a significant number of jurisdictions (City and County of Denver, Arapahoe County,

Greenwood Village, USACE, etc.)

2. Urban construction. Proposed alignment corridors will encounter heavily traveled and constrained

roadways with a very high number of existing utilities.

Line Loop: 40120

Project Scope:

Replace approximately 5 miles of 20" pipeline along the 20" Parker high pressure gas main. This segment has been identified to be lacking the necessary records to support its MAOP. This segment does not have traceable, verifiable, and complete pressure test records in a class 3 area. This lack of traceable, verifiable, and complete records was identified as part of the review of historical pipeline MAOP records.

ROW:

The existing pipeline alignment is located in a heavily populated residential area that is infeasible for replacement in the existing ROW. This project will need to obtain additional ROW to install a high pressure pipeline in a more suitable route.

Capacity:

Project will be a like-for-like replacement of the existing 20" pipe. Because this pipeline had to be rerouted out of the existing alignment, a portion of the existing 20" pipeline will be derated to a distribution pipeline and will continue to serve the existing reg stations that are required to remain in service.

(2021)

Project Scope:

Replace approximately 6,400' of 2.5" pipeline along the 3" (4") East Hayden to Steamboat gas transmission line. This segment along the line has been identified to be lacking the necessary records to support its MAOP. This segment does not have traceable, verifiable, and complete pressure test records in a class 3 area. This lack of traceable, verifiable, and complete records was identified as part of the review of historical pipeline MAOP records.

ROW: Pipeline will be rerouted in order to avoid landslide area that was discovered

during initial engineering.

Capacity: Pipeline to be replaced is 2.5" which is not a common main size used by

the industry. Pipeline will be upsized to 4". Installing a 2" would have decreased capacity on system; therefore, installation of 4" pipeline required in order to be able to continue serving existing customers
