Proposed Fox Creek 33 Compressor Station
Soils Report
Soils affected by the proposed Fox Creek 33 Compressor station were evaluated for a number
of factors to assess potential Project impacts . An assessment of existing soil quality or sensitivity
was completed by evaluating the following factors: wind and water erodibility, prime farmland ,
hydric characteristics, and drainage characteristics . Soil disturbances can increase the potential
for erosion, which can cause topsoil to be lost, and can negatively affect soil stability and quality.
construction can also result in mixing of topsoil with subsoil , resulting in reduced soil structure
and stability, soil fertility, and important soil biological function .. The following table lists the
characteristics and soil limitations of each series for the proposed Fox Creek 33 Compressor
Station .
At the proposed Fox Creek 33 Compressor Station , soil data provided by NRCS (shown on the
attached figure) indicates that the two soil types present within the Project footprint;
• one is susceptible to water erosion ,
• none are susceptible to wind erosion ,
• one is classified as a farmland of statewide importance ,
• both are considered well drained ,
• none are classified as hydric.

b Soils in wind erodibility groups 5 and 6 are considered to have an erosion potential due to wind .
c Prime farmland includes categories : Prime farmland if irrigated , and farmland of statewide importance , not prime
farmland as designated by the NRCS .

f includes soils that have clay loam or finer textures and are somewhat poor, poor, or very poor drainage classes.

The soil units of the site would not be a limiting factor to the construction and long-term operation
of the proposed Fox 33 Compressor Station . To mitigate the impacts of construction on Project

soils, grading and clearing of vegetation would be conducted only to provide adequate
construction and operational staging and access to the Project areas.
To reduce the potential for erosion , disturbance or removal of vegetation would be kept to the
least extent practical for safe construction conditions . Areas disturbed from construction activities
that are not actively cultivated would be re-seeded using a mix of annual and perennial species
established through consultation with the local Natural Resources Conservation Service (NRCS )
and landowner. Reseeding would not be performed where surface facilities require the site to be
maintained in a vegetation-free condition.
