Dear Mr. Jarman,
Please consider the attached documentation our application for a Development Plan
Review for Right -of -Way for the Mid-America Pipeline Company, LLC- Western
Expansion Project II (WEP II).
Project Overview
Mid-America Pipeline Company, LLC has prepared the attached materials with the intent
to receive permits necessary to construct the Western Expansion Project II. The purpose
of this project is to construct a 16 -inch natural gas liquids pipeline from the Dragon
Compressor Station in Uintah County, Utah to the Thompson Springs Compressor
Station in Grand County, Utah. This pipeline is proposed to be constructed through Rio
Blanco County, Garfield County and Mesa County, Colorado. The entire pipeline length
is approximately 95 miles.
This natural gas liquids pipeline will connect existing facilities in Utah to Mid-America
Pipeline Company, LLC facilities in Grand County, Utah.

The pipeline is being proposed to provide safe, reliable and cost effective transportation
of natural gas liquids produced in the area.
Project Description
The project is a proposed pipeline consisting of approximately 25 miles of new 16 -inch
diameter pipeline within Garfield County, Colorado. The pipeline is 1,650 psig MAOP
(Maximum Allowable Operating Pressure). The pipeline is located within Garfield
County, Colorado. The project is largely located within and adjacent to multiple existing
pipeline right-of-ways.
Pipeline right-of-way Length and Widths — The total project right-of-way length is
approximately 25 miles in length located on fee land and Bureau of Land Management
properties.
The temporary use right-of-way on the project is generally 75 feet in width. The
permanent easement on the project is generally 50 feet in width for a total disturbed area
of 125 feet in width. Please see alignment sheets in Tab 2, specifically the "Right -of -
Way" section for details at each parcel.
As per the Garfield County Unified Land Use Resolution of 2008, as amended, Section 9-
102, "Development Plan Review for Pipeline Right -of -Way", Mid-America Pipeline
Company, LLC is required to apply for a Development Plan Review for Right -of -Way
because the proposed pipeline is "greater than 12" in diameter and over 2 miles in
length".
We have located the new pipeline largely, in existing, disturbed right-of-way to limit
surface disturbance.
The design and construction of the pipeline system will be in accordance with applicable
regulations, recognized industry codes and the normal and customary practice for these
type of facilities. The gas line design is compliant with the applicable sections of the
Code of Federal Regulations Title 49, Part195 Transportation of Hazardous Liquids by
Pipeline and ASME B31.4-2009- Pipeline Transportation Systems for Liquid
Hydrocarbons and Other Liquids.
Pre -Application Conference
A pre -application conference was held on November 1, 2011 with Molly Orkild-Larson-
Garfield County Senior Planner to discuss the project. Please find attached a copy of the
pre -application form prepared by Ms. Orkild-Larson.
