Form 2A Document No. 403534889
Garfield County, Colorado
Dear Director Murphy,
Chevron USA, Inc. has filed a Form 2A with the Colorado Energy and Carbon Management
Commission (ECMC) for the above referenced location. ECMC Rule 304.d. stipulates that the
Director may exempt an Operator from submitting any of the information required by Rule 304.b.
or any plan required by Rule 304.c. Chevron respectfully requests an exemption from the Director
based on evidence showing the information or plan is unnecessary because the impacted resource
or resource concern is not present in the area; or impacts to the resource will be so minimal as to
pose no concern. Please see the attached Table for details.
Pursuant to ECMC Rule 304.d.(2), Operators may request an exemption from the Director in writing,
without proceeding through the ordinary Rule 502 variance process. A request for an exemption
will be provided with the Form 2A at the time the Form is submitted. This letter serves as the
required exemption request.
If you should have any questions or require additional information, please do not hesitate to
contact me at your earliest convenience at (970)304-5057, or dougdennison@chevron.com.

Provide a qualitative evaluation of any potential acute or chronic, short- or long-term incremental impacts to public health as a result of the
estimated total pre-production hazardous air pollutant emissions.
Modern flowback technology that will be employed for OGDP SKR 698-10-BV eliminates uncontrolled emission flowback point
sources. Due to these updates, the emissions of HAP during pre-production activities will be predominately those that come from
engines powering drilling and completions equipment. Therefore, no incremental impacts to public health will result from pre-
production activities outside of the well pad.
Provide a qualitative evaluation of any potential acute or chronic, short- or long-term incremental impacts to public health as a result of the
estimated annual production hazardous air pollutant emissions.
Chevron prepared a Cumulative Impacts Plan and this plan has been submitted with this location’s 2A. Based on the review of the
specific hazardous pollutant emissions and other emissions, as detailed in the Air Resources section of the Cumulative Impacts Plan,
there should not be any chronic, short- or long-term incremental adverse impacts to Public Health. Chevron's advanced flowback and
production designs have significantly reduced the short- and long-term emissions associated with these activities. The emissions
removed in conjunction with the remote nature of the locations will have minimal Public Health impacts to the areas surrounding the
SKR 698-10-BV OGDP.

meeting OSHA requirements inside the boundaries of location.
Provide an evaluation of the proposed proppant management system that will be used to minimize dust during completions activities,
including the estimated amount of silica dust that will leave the Oil & Gas Location.

There are primarily two (2) recurring themes that are the Driving Forces contributing not only to offsetting and mitigating adverse
Cumulative Impacts, but also to promoting beneficial Cumulative Impacts. The 2 Driving Forces are as follows: 1) Implementation of
technologically advanced completion and production designs engineered to significantly reduce overall impacts. 2) Going beyond
compliance to enhance ecosystem restoration and land conversion back to vegetative states, enabling carbon capture and
sequestration.
Provide a qualitative evaluation of any incremental beneficial impacts to the surrounding wildlife and ecosystems directly and indirectly

environment.
BENEFICIAL IMPACT INFORMATION
MITIGATION INFORMATION
No Mitigation Measures Listed
Number of miles of the existing lease road that are planned to be used to access these location(s):
Total disturbed acreage including pad, access road, and flowline corridor within HPH Habitat is 16.4 acres when including the
existing 6.2 acre Storage Facility. Total permanent HPH acreage after interim reclamation will be 2.4 acres.
The existing Skinner Ridge Storage Facility currently on this location has a disturbance acreage of 6.2 acres. Although the existing
location can safely accommodate the proposed drilling and completions operations, it is smaller than what Chevron would consider
an ideal size for operations on the proposed SKR 698-10-BV Pad; therefore, the use of the existing pad results in approximately 1.5
acres less of disturbance than would occur if a new location was constructed. Additionally, there will be a net reduction of 3.8 acres
from the existing usage after interim reclamation. These factors combine to provide a total net benefit of 5.3 acres of undisturbed
HPH when compared to constructing a new location.

Re: Chevron Piceance
SKR-698-10 BV Pad
Garfield County, CO
LSC #240050
Dear Ms. McRedmond:
In response to your request, LSC Transportation Consultants, Inc. has prepared this basic
traffic analysis for the proposed Chevron Piceance SKR-698-10 BV Pad development. As shown
on Figure 1, the site is located east of County Road 211 in rural Garfield County, Colorado.
REPORT CONTENTS
The report contains the following: the proposed site plan; haul route; existing easements along
the haul route; the existing daily traffic volumes along the haul route; the estimated daily trips
generated by the site for various phases; and the total daily traffic along the haul route during
the two heaviest trip-generating phases.
LAND USE AND ACCESS
The existing site is currently being used as Chevron’s Skinner Ridge Storage Facility. Chevron
will relocate the existing storage equipment and utilize the existing pad to drill two horizontal
wells. Full movement access is proposed to CR 211 as shown in Figure 2. Figure 3 shows the
proposed haul route. Figure 4 shows the existing easements along the haul route. The attached
Chevron transportation plan shows the site access road from CR 211.
ROADWAY AND TRAFFIC CONDITIONS
Area Roadways
The major roadways in the site’s vicinity are shown on Figure 1 and are described below.
• CR 204 is a north-south, two-lane paved county road south of the site. It serves as the
southern portion of the haul route and connects to I-70. There is an existing northbound
to eastbound right-turn lane on CR 204 approaching CR 211 which is the northern portion
644
Ms. Kristi McRedmond Page 2 March 8, 2024
Chevron-Piceance SKR-698-10 BV Pad
of the haul route. The posted speed limit is 45 mph near CR 211 but reduces to 40 mph
closer to I-70 to the south.
•CR 211 is a north-south, two-lane gravel county road west of the site. It serves as the
northern portion of the haul route. The approach of CR 211 to CR 204 is paved which
benefits intersection operations. Sight distance is good in each direction of CR 204 from
CR 211.
Existing Traffic Conditions
Figure 4 shows the existing easements and Figure 5 shows the existing average daily traffic
volumes along the haul route based on Garfield County data. The applicant indicates they
currently have about 20 pickup trucks and three heavy trucks using the CR 211 corridor for
existing operations.
TRIP GENERATION
Table 1 shows the estimated daily trip generation for the proposed site for five phases of deve-
lopment based on information provided by the applicant.
The site is projected to generate about 61 vehicle-trips on the average weekday during the
construction phase; about 353 one-way vehicle-trips per day during the drilling phase; about
343 one-way vehicle-trips per day during the completions phase; and about 17 one-way vehicle-
trips per day during the interim reclamation phase. During the production phase, the site’s trip
generation will generally be lower but will vary because production trips will be combined for
multiple locations within the Piceance Basin whenever possible.
TRIP ASSIGNMENT
Figure 6 shows the estimated average daily traffic assignment along the haul route for the two
highest trip generating phases.
TOTAL TRAFFIC
Figure 7 shows the estimated average daily total traffic along the haul route during the two
highest trip generating phases.
COUNTY ACCESS PERMIT
A driveway/access permit will be required and will be submitted with the oil and gas permit
application.
CDOT OR RAILROAD PERMIT
The applicant indicates no permits are needed from CDOT or any Railroads.
645
Ms. Kristi McRedmond Page 3 March 8, 2024
Chevron-Piceance SKR-698-10 BV Pad
COUNTY OR STATE PERMITS
The ECMC OGDP Form 2A approval permits were submitted in December, 2023. The Garfield
County Oil and Gas permit application will be submitted when ready. This will include the re-
quired driveway/access permit application.
EXISTING EASEMENTS ALONG THE HAUL ROUTE
Figure 4 shows the existing easements along the haul route.
CHEVRON TRANSPORTATION PLAN AND DUST MITIGATION PLAN
The transportation plan and dust mitigation plan prepared for the site are attached for refe-
rence. The transportation plan shows the proposed access road from CR 211 into the site.
CONSTRUCTION PHASING
All staging and storage of materials will occur on Chevron property near the proposed site.
There is no need for temporary access or lane closures anticipated.
CONCLUSIONS AND RECOMMENDATIONS
Trip Generation
1. The site is projected to generate about 61 vehicle-trips on the average weekday during the
construction phase; about 353 one-way vehicle-trips per day during the drilling phase;
about 343 one-way vehicle-trips per day during the completions phase; and about 17 one-
way vehicle-trips per day during the interim reclamation phase. During the production
phase, the site’s trip generation will generally be lower but will vary because production
trips will be combined for multiple locations within the Piceance Basin whenever possible.
Conclusions
2. The impact of the Chevron Piceance SKR-698-10 BV Pad can be accommodated by the
existing and planned roadway network with the following recommendations.
Recommendations
3. The applicant should follow the transportation plan and dust mitigation plan details as
well as follow all permit requirements.

• At the time of construction, all leasehold roads shall be constructed to accommodate
local emergency vehicle access requirements and shall be maintained in a reasonable
condition.
• Flowlines from the well pad to the production facilities will be constructed prior to
starting flowback operations to eliminate truck traffic associated with flowback and
production.
• Production operations are continuously monitored remotely from Chevron’s Operations
Control Center (OCC) to minimize the need for personnel to drive to the location.
• A speed limit of 20 MPH will be enforced on the unpaved private roads.
• Chevron will employ practices for control of fugitive dust caused by operations,
including speed restrictions, regular road maintenance, restriction of construction
activity during high wind days, and silica dust controls when handling sand used in
hydraulic fracturing operations. Additional management practices such as road
surfacing, wind breaks and barriers, or automation of wells to reduce truck traffic may
also be used to minimize fugitive dust emissions.
