RE: Wildlife Health Standards Analysis
OXY USA WTP LP Proposed 604-12-13 Storage Area
Dear Ms. Middleton,
On October 7, 2014, ERO Resources Corporation (ERO) conducted a biological
resource survey for the proposed 604-12-13 storage area in the Grand Valley Field on
behalf of OXY USA WTP LP (Oxy). 604-12-13 is located approximately 15 miles
north of DeBeque in Garfield County, Colorado. This document is intended to
supplement a Land Use application to Garfield County.
Location and Existing Conditions
For the purposes of the proposed project, the survey area was defined as
approximately 4.2 acres surrounding the existing project envelope (Figure 1). The
legal location of the approximate center of the project area is Sections 4 and 5, T6S,
R97W; 6th PM; UTM NAD 83: Zone 12N; 737760mE, 4381851mN; Latitude,
Longitude: 39.553423°N, 108.23276°W; USGS Circle Dot Gulch, CO Quadrangle;
Garfield County, Colorado. Oxy is the surface owner.
Proposed Project
The site's main function will be to provide a storage site for oil and gas equipment
and supplies with existing disturbance footprints. The site previously was developed
with a pad built and a plugged well located within the site perimeter. No new grading
disturbance would be required. Stormwater features currently exist on-site. The
proposed storage area will not require lighting, utilities, water, or wastewater. The site
will not be manned and will be occupied only for un/loading of equipment and
supplies. The site will not store waste, hazardous materials, or any materials that may
cause odors or nuisances to adjacent parcels.
Environmental Setting
An ERO natural resource specialist completed a site review of the proposed
project area on October 7, 2014. The site review was conducted for environmental
permitting or clearance issues, including wetlands and waters of the U.S., threatened
and endangered species habitat, migratory birds, and noxious weeds. Colorado Parks
and Wildlife (CPW) habitat and species/nest occurrence maps were referenced prior to
and during field surveys. ERO also reviewed the most recent aerial photography

(2011), U.S. Fish and Wildlife Service Information, Planning, and Conservation
documents (USFWS 2014), State of Colorado (Colorado Department of Agriculture
2014) and the Garfield County Noxious Weed Lists (Garfield County 2014). National
Resource Conservation Service (NRCS 2014) soil maps were also referenced prior to
site review.
The 604-12-13 proposed project area is located at an approximate elevation of
8,500 feet above sea level (Figure 2). The existing pad footprint and access road are
maintained gravel surfaces containing minimal to no vegetation. The surrounding area
consists of mixed mountain scrub -shrub habitat dominated by sagebrush (Artemesia
tridentata sp. wyomingensis) and Gambel's oak (Quercus gambelii). The sagebrush
and oak stands belong to a mostly mature age class. The northern edge of the existing
pad is excavated rock/cliff habitat. Table 1 lists common vegetation observed within
the project area.

Proposed site modifications will not significantly alter the existing visual and
sound buffers.
Locational Controls of Land Disturbance
No grading is proposed at the 604-12-13 site, and is therefore not anticipated to
change animal migration corridors or predation dynamics. No increase in traffic is
anticipated, so there would not be a change to existing animal -vehicle collision
occurrences. Site conditions and activities would remain very similar to current
conditions.
Preservation of Native Vegetation
Oxy will adhere to their Noxious Weed Management Plan for all project activities.

Habitat Compensation
Proposed site modifications are not anticipated to require habitat compensation.
No designated big game habitat areas are located within 1.0 mile of the project area.
The existing site does not contain suitable habitat for greater sage -grouse.
Domestic Animal Control
Domestic animals and livestock are currently allowed within the project area;
however, impacts to domestic animals/livestock are not anticipated by proposed site
modifications.
