ATLANTIC SUNRISE PROJECT
INITIAL DRAFT RESOURCE REPORT NO. 1 – GENERAL PROJECT DESCRIPTION
Central Penn Line North
Central Penn Line (CPL) North will consist of approximately 56.1 miles of new 30-inch
diameter pipeline in Pennsylvania with a maximum allowable operating pressure (MAOP) of
1,480 pounds per square inch gauge (psig). This proposed pipeline will be co-located within or
adjacent to Transco’s Leidy Line pipeline right-of-way (ROW) for approximately 21.0 miles. CPL
North will commence near approximate MP L113.8 of the existing Transco Leidy Line pipeline in
Columbia County and continue east for approximately 21.0 miles along Transco’s Leidy Line A
ROW. Near approximate MP 21.0 in Luzerne County, the pipeline will turn northeast separating
from the existing Transco Leidy Line system continuing for approximately 35.1 miles through
Wyoming and Susquehanna counties, Pennsylvania to the proposed receipt meter station at the
existing Williams Zick Compressor Station in Susquehanna County. The existing Williams Zick
Compressor Station is owned and operated by Williams Midstream. Other areas of co-location
are provided in Table 1.2-2, in Section 1.2.
Central Penn Line South
CPL South will consist of approximately 121.3 miles of new greenfield 42-inch diameter
pipeline in Pennsylvania with an MAOP of 1,480 psig. The pipeline is currently proposed to be
co-located within or adjacent to existing pipeline or electric transmission utility rights-of-way as
provided in Table 1.2-2, in Section 1.2 below. CPL South is currently proposed to commence
near approximate MP 1683.0 of the existing Transco Mainline system in Lancaster County and
will continue north through Lebanon, Schuylkill, Northumberland, and Columbia counties,
Pennsylvania, before reaching its terminus near approximate MP L113.8 of the existing Transco
Leidy Line pipeline.
Grugan Loop
The Grugan Loop will consist of approximately 5.5 miles of 36-inch pipeline co-located
with the existing Transco Leidy Line between MPs L171.8 and L177.3 in Clinton County,
Pennsylvania. Once placed into operation, Transco will refer to the Grugan Loop as the Leidy
Line E.
Unity Loop
The Unity Loop will consist of approximately 9.0 miles of 42-inch pipeline co-located with
The existing Transco Leidy Line pipeline between approximate MPs L119.9 and L128.9 in
Lycoming County, Pennsylvania. Once placed into operation, Transco will refer to the Unity
Loop as the Leidy Line D.
