floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
current and future land use, etc.)
The Working Pad Surface of the recommended Well Pad is within the Aquatic Sportfish
Management Waters designation by Rule 1202.c., associated with Deer Park Gulch. In addition,
the Working Pad Surface of the Well Pad is within the Elk Severe Winter Range and Elk Winter
Concentration areas designation by Rule 1202.d. In recognition of these designations, Chevron
proposes the following minimization and mitigation measures:
• Chevron intends to utilize the existing surface disturbance of the Well Pad with minimal
additional disturbance required for development. Any additional disturbance would be to
allow for a separate access point on the northwestern end of the Well Pad and an
infrastructure tie-in associated with constructing a fluid line to the pad. This threshold
matter demonstrates that reuse of existing disturbance necessarily translates into less
surface disturbance that could lead to riparian erosion or audible distractions and
competing use of space by big game.
• Chevron will implement mitigation measures along the existing section of the access road
to minimize impacts to the Aquatic Sportfish Management Waters associated with Deer
Park Gulch. These include, but are not limited to:
o Stormwater management grading;
o Speed limits to maximize road integrity;
o Road grading management plan;
o Rock netting.
• The proposed new access point to the Well Pad will be further removed from Deer Park
Gulch (over 400 feet) than the existing access (approximately 40 feet).
• Chevron will voluntarily operate this Well Pad under the standards of an adjacent federal
BLM lease. While BLM minerals or leases are not a part of this OGDP, Chevron’s
research indicated that the immediately adjacent lease includes many reasonable and
detailed stipulations that protect not only sportfish and big game, but also a host of other
species and environmental considerations. Chevron will operate solely under ECMC
authority in this regard, but these additional and voluntary measures provide additional
layers of review and protection that benefit the proposed location. Please see the Rule
505 regulatory testimony for a list of these stipulations.
• There are zero RBUs, HOBUs, Schools, School Facilities or Child Care Centers within
2,000 feet of the recommended Working Pad Surface of the Well Pad.
Permitting Considerations:
The Well Pad has a legacy ECMC Location ID of 336056. The Location ID has an active status
with the ECMC, but the original permits related to the Location ID have since expired and the
existing disturbance was re-purposed and permitted through Garfield County land use code as
an equipment storage facility. Chevron is required to submit an Oil and Gas Development Plan
(“OGDP”) with the ECMC to add two (2) horizontal wells and associated production equipment to
Location ID 336056. Chevron will work with Garfield County under its oil & gas regulations to
update the existing Garfield County records associated with the Well Pad and apply for a Garfield
County Oil and Gas Permit. Chevron intends to submit the application for a Garfield County Oil
and Gas Permit concurrently with the OGDP application and will provide documentation of the
approved Garfield County Oil and Gas Permit to the ECMC upon approval.
81
The Well Pad is located within an income-based DIC designation according to CDPHE’s
EnviroScreen. Although the Well Pad is within a DIC, the Working Pad Surface is not within 2,000
feet of any RBU, HOBU, or School Facility.
Summary:
The Well Pad is Chevron’s recommended location as it allows for efficient development of the
targeted resources within the operational corridors of the OGDP while maximizing protection of
public health, safety, welfare, environment, and wildlife. The Well Pad will feature advanced
technological design solutions such as tankless production, elimination of flare stacks, and a
closed loop system. While there are alternate locations located outside of Rule 1202.c. Aquatic
Sportfish Management Waters NSO, the recommended Well Pad utilizes existing surface
disturbance that doesn’t have other wells or production equipment taking up the Working Pad
Surface and can be fully utilized for the target hydrocarbons associated with the OGDP. Although
the Well Pad is within a DIC, the Working Pad Surface is not within 2,000 feet of any RBU, HOBU,
or School Facility. The Well Pad was selected following extensive review of operational
parameters to minimize and consolidate locations while allowing for targeted mineral recovery
and being mindful of the surrounding surface features.

ALTERNATIVE OIL AND GAS LOCATION #1 (“AL 1”)
Legal: Township 5 South, Range 97 West, 6th P.M., Section 31
Location ID: 324443
Tier: TIER III-A
AL 1 would utilize previously disturbed ground associated with ECMC Location ID 324443.
Location ID 324443 is an abandoned ECMC location and has been reclaimed with native
vegetation. This location is on top of a bluff, which can create certain access constraints and
safety considerations during the winter season. There’s an existing access road related to TEP
Rocky Mountain LLC operations associated with Location ID 324380, but the legacy access to
AL 1 (approximately four tenths of a mile) would likely need to be re-built and improved in order
to accommodate the drilling and completions of two (2) horizontal wells. The nearest surface
water to AL 1 is approximately 836 feet to the northwest. Chevron is the surface owner where AL
1 is located.
Advantages:
• AL 1 is previously disturbed ground (Location ID 324443).
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 1 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 1 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 1 is greater than 2,000 feet from a jurisdictional boundary.
• AL 1 is fully outside of Rule 1202.c. NSO.
• AL 1 is outside of Rule 1202.d. Density Habitat related to Elk Severe Winter Range and
Elk Winter Concentration.
• AL 1 is adequate for developing the targeted minerals associated with the proposed unit
based on drilling step-out capabilities.
Disadvantages:
• Chevron submitted a request for Final Reclamation approval in February 2023. AL 1
would require Chevron to rebuild and improve the reclaimed location and access, resulting
in approximately 6.97 acres of disturbance.
• Access is not possible from Clear Creek Road on West side; access would come from the
East side access from Garden Gulch Road requiring 15 miles and stretches of road
expansion needed.
• AL 1 is within Rule 1202.d. Greater Sage Grouse General Habitat Area and Greater Sage
Grouse Priority Habitat Area.
• This location is within a Disproportionately Impacted Community.
• There’s no existing pipeline infrastructure to AL 1, so gas and fluid line connections would
need to be made to the location.
• The location is on top of a bluff, which can have limited access during certain winter
months or weather events.
• The data collection for the deeper, non-oil and gas producing formations will be more
expensive when starting from the top of the bluff.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
83
current and future land use, etc.)
The Working Pad Surface of AL 1 is within Rule 1202.d. Greater Sage Grouse General Habitat
Area and Greater Sage Grouse Habitat Area designations. Utilizing the reclaimed area
associated with AL 1 would re-disturb approximately 6.97 acres for the pad to accommodate two
(2) horizontal wells, associated production equipment, and access road. There are zero RBUs,
HOBUs, Schools, School Facilities, or Child Care Centers within 2,000 feet of the Working Pad
Surface of AL 1.
Permitting Considerations:
AL 1 has a legacy ECMC Location ID of 324443. In February 2023, Chevron requested Final
Reclamation approval of the previously disturbed ground. Chevron is required to submit an
OGDP with the ECMC to add two (2) horizontal wells and associated production equipment to
Location ID 324443. The Relevant Local Government for AL 1 is Garfield County. Based on the
presence of High Priority Habitat, AL 1 would trigger an ALA review. Pursuant to Garfield County
oil and gas code, if an ALA is completed as part of an oil and gas application it is to be reviewed
at the Garfield County Pre-Application Meeting. Chevron intends to submit the application for a
Garfield County Oil and Gas Permit concurrently with the OGDP application. AL 1 is located
within an income-based DIC designation according to CDPHE’s EnviroScreen. Although the Well
Pad is within a DIC, the Working Pad Surface is not within 2,000 feet of any RBU, HOBU, or
School Facility.
Summary:
AL 1 has the benefit of being fully outside of Rule 1202.c. Aquatic Sportfish Management Area,
Rule 1202.d. Elk Severe Winter Range, and Rule 1202.d. Elk Winter Concentration as compared
to the recommended Well Pad. AL 1 would have similar opportunity to develop the target minerals
compared to the recommended Well Pad and both locations are within the same DIC block group.
However, AL 1 is within Rule 1202.d. Greater Sage Grouse General Habitat Area and Greater
Sage Grouse Priority Habitat Area. AL 1 would be approximately 6.97 acres of surface
disturbance of previously reclaimed ground utilized for Working Pad Surface and access road.
The location of AL 1 on the top of the bluff will also require significantly increased travel distances
and associated dust and other emissions and potential impact to wildlife. The ALA criteria of
being approximately 6.97 acres of surface disturbance in Greater Sage Grouse Priority Habitat
Area and the need for both gas and fluid pipeline infrastructure to be constructed to AL 1 is why
the Well Pad is recommended for the proposed development.

ALTERNATIVE OIL AND GAS LOCATION #2 (“AL 2”)
Legal: Township 6 South, Range 98 West, 6th P.M., Section 10
Location ID: 383178
Tier: TIER III-A
AL 2 is an abandoned PDC Energy, Inc. location (Location ID 383178) that appears to have never
been constructed; thus, AL 2 would require all new surface disturbance. In addition to the new
well pad disturbance, approximately 1,100 feet of new road will need to be constructed to access
AL 2 (additional surface disturbance of approximately 0.75 acres). This is in a relatively flat area
between Deer Park Gulch (and associated NSO) to the south and Doe Gulch to the north. The
nearest surface water is Doe Gulch, which is approximately 40 feet to the northwest of AL 2.
Mahogany Energy Resources, LLC is the surface owner where AL 2 is located.
Advantages:
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 2 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 2 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 2 is greater than 2,000 feet from a jurisdictional boundary.
• Vast majority (if not all) of the AL 2 disturbance could be outside of Rule 1202.c. NSO.
• AL 2 is a relatively flat area that could likely avoid significant construction impacts to the
surrounding terrain.
• AL 2 is accessible to tie into existing gas infrastructure.
• AL 2 is adequate for developing the targeted minerals associated with the proposed unit
based on drilling step-out capabilities.
Disadvantages:
• The existing Location ID has never been constructed. AL 2 will be brand new surface
disturbance and require approximately two-tenths of a mile of new access road.
• AL 2 is within Rule 1202.d. Elk Winter Concentration and Elk Severe Winter Range areas.
• AL 2 is within a Disproportionately Impacted Community.
• There’s no existing infrastructure for fluid takeaway at AL 2. A fluid line would need to be
installed.
• A significant amount of topography exists with AL 2.
• The nearest surface water is approximately 40 feet to the northwest.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
current and future land use, etc.)
The Working Pad Surface of AL 2 is within Rule 1202.d. Elk Winter Concentration and Elk Severe
Winter Range area designations. This would be brand new disturbance to accommodate two (2)
horizontal wells, associated production equipment, and access road. There are zero RBUs,
HOBUs, Schools, School Facilities, or Child Care Centers within 2,000 feet of the Working Pad
Surface of AL 2.
85
Permitting Considerations:
AL 2 has a legacy ECMC Location ID of 383178 (abandoned location). It appears the location
was never constructed. Chevron is required to submit an OGDP with the ECMC to add two (2)
horizontal wells and associated production equipment to Location ID 383178. The Relevant Local
Government for AL 2 is Garfield County. Based on the presence of High Priority Habitat, AL 2
would trigger an ALA review. Per Garfield County oil and gas code, if an ALA is completed as
part of an oil and gas application it is to be reviewed at the Garfield County Pre-Application
Meeting. Chevron intends to submit the application for a Garfield County Oil and Gas Permit
concurrently with the OGDP application. Since Chevron is not the surface owner where AL 2 is
located, a Surface Use Agreement would be needed for the OGDP and Garfield County
application process. AL 2 is located within an income-based DIC designation according to
CDPHE’s EnviroScreen. Although the Well Pad is within a DIC, the Working Pad Surface is not
within 2,000 feet of any RBU, HOBU, or School Facility.
Summary:
AL 2 has the benefit of having a majority of the Working Pad Surface outside of Rule 1202.c.
Aquatic Sportfish Management Area compared to the recommended Well Pad. AL 2 would have
similar opportunity to develop the target minerals as the recommended Well Pad, and both
locations are within the same DIC block group, Rule 1202.d. Elk Winter Concentration, and Rule
1202.d. Elk Severe Winter Range. AL 2 would be brand new surface disturbance for the Working
Pad Surface and accompanying access road into the location, which is why utilizing the existing
surface disturbance associated with the Well Pad is recommended for the proposed development.
86
ALTERNATIVE OIL AND GAS LOCATION #3 (“AL 3”)
Legal: Township 6 South, Range 98 West, 6th P.M., Section 10
Location ID: 383173
Tier: TIER III-A
AL 3 is an abandoned PDC Energy, Inc. location (Location ID 383173) that appears to have never
been constructed; thus, AL 3 would require all new surface disturbance. There’s adequate access
to AL 3; however, there would need to be a short road crossing over Deer Park Gulch in order to
connect AL 3 with the existing road infrastructure. This is in a relatively flat area immediately
adjacent to Deer Park Gulch, which is the nearest surface water located approximately 49 feet to
the south/southwest. Mahogany Energy Resources, LLC is the surface owner where AL 3 is
located.
Advantages:
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 3 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 3 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 3 is greater than 2,000 feet from a jurisdictional boundary.
• AL 3 is a relatively flat area that could likely avoid significant construction impacts to the
surrounding terrain.
• AL 3 is accessible to tie into existing gas infrastructure.
• AL 3 is likely adequate for developing the targeted minerals associated with the proposed
unit based on drilling step-out capabilities (slight unit modifications possibly needed).
• The data collection for the deeper, non-oil and gas producing formations will be more
easily accessible when starting from the lower-lying valley area associated with AL 3.
Disadvantages:
• The existing Location ID doesn’t appear to have ever been constructed. AL 3 will be brand
new surface disturbance and require construction of additional road over Deer Park Gulch
for location access.
• AL 3 is within Rule 1202.c. Aquatic Sportfish Management Waters NSO.
• AL 3 is within Rule 1202.d. Elk Severe Winter Range and Elk Winter Concentration density
habitats.
• This location is within a Disproportionately Impacted Community.
• Any shift or expansion to the north would further remove operations from Rule 1202.c.
NSO but would likely require significant construction cuts into the existing terrain.
• There’s no existing infrastructure for fluid takeaway at AL 3. A fluid line would need to be
installed.
• The nearest surface water is Deer Creek Gulch which is approximately 49 feet from AL 3.
• Chevron does not have, nor can it guarantee, contractual access to the proposed location.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
current and future land use, etc.)
The Working Pad Surface of AL 3 is within Rule 1202.c. Aquatic Sportfish Management Waters
87
and Rule 1202.d. Elk Winter Concentration and Elk Severe Winter Range habitats. AL 3 would
be brand new disturbance to accommodate two (2) horizontal wells, associated production
equipment, and access road. The access to AL 3 would require a new connection over Deer Park
Gulch from the existing road. There are zero RBUs, HOBUs, Schools, School Facilities, or Child
Care Centers within 2,000 feet of the Working Pad Surface of AL 3.
Permitting Considerations:
AL 3 has a legacy ECMC Location ID of 383173 (abandoned location). It appears the location
was never constructed. Chevron is required to submit an OGDP with the ECMC to add two (2)
horizontal wells and associated production equipment to Location ID 383173. The Relevant Local
Government for AL 3 is Garfield County. Based on the presence of High Priority Habitat, AL 3
would trigger an ALA review. Per Garfield County oil and gas code, if an ALA is completed as
part of an oil and gas application it is to be reviewed at the Garfield County Pre-Application
Meeting. Chevron intends to submit the application for a Garfield County Oil and Gas Permit
concurrently with the OGDP application. Since Chevron is not the surface owner where AL 3 is
located, a Surface Use Agreement would be needed for the OGDP and Garfield County
application process. AL 3 is located within an income-based DIC designation according to
CDPHE’s EnviroScreen. Although the Well Pad is within a DIC, the Working Pad Surface is not
within 2,000 feet of any RBU, HOBU, or School Facility.
Summary:
The ALA criteria associated with AL 3 is similar to the recommended Well Pad. Both locations
are within Rule 1202.c. Aquatic Sportfish Management Area, Rule 1202.d. Elk Severe Winter
Range, and Rule 1202.d. Elk Winter Concentration. In addition, AL 3 would have similar
opportunity to develop the target minerals, is accessible to existing gas infrastructure, and within
the same DIC block group as the recommended Well Pad. The main difference between AL 3
and the recommended Well Pad is that AL 3 will be brand new surface disturbance on lands not
owned by Chevron. For that reason, the Well Pad is recommended over AL 3.
88
ALTERNATIVE OIL AND GAS LOCATION #4 (“AL 4”)
Legal: Township 6 South, Range 98 West, 6th P.M., Sections 15 & 16
Location ID: N/A
Tier: TIER IV-B
AL 4 is brand new surface disturbance unaffiliated with any legacy ECMC Location ID. AL 4 is
on irrigated property that’s primarily used for growing hay and grazing livestock. There’s adequate
access to AL 4 given the presence of Clear Creek Road to the northeast. This is in a relatively
flat area immediately adjacent to where Clear Creek and Deer Park Gulch intersect. The nearest
surface water is Clear Creek which is approximately 204 feet to the southwest. Chevron is the
surface owner where AL 4 is located.
Advantages:
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 4 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 4 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 4 is greater than 2,000 feet from a jurisdictional boundary.
• AL 4 is a relatively flat area that could likely avoid significant construction impacts to the
surrounding terrain.
• AL 4 is accessible to tie into existing gas infrastructure.
• AL 4 is likely adequate for developing the targeted minerals associated with the
proposed unit based on drilling step-out capabilities (slight unit modifications possibly
needed).
• The data collection for the deeper, non-oil and gas producing formations will be more
easily accessible when starting from the lower-lying valley area associated with AL 4.
Disadvantages:
• AL 4 is brand new surface disturbance that would disrupt current agricultural production
and livestock grazing operations.
• AL 4 is within Rule 1202.c. Aquatic Sportfish Management Waters NSO.
• AL 4 is within Rule 1202.d. Elk Severe Winter Range and Elk Winter Concentration
density habitats. Based on Chevron observations as surface owner, AL 4 is frequented
elk habitat given the location’s proximity to Clear Creek.
• AL 4 would be located in grazing area for wildlife.
• AL 4 is immediately upgradient of a riparian area.
• This location is within a Disproportionately Impacted Community.
• The nearest surface water is Clear Creek which is approximately 204 feet from AL 4.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community
(“DIC”), current and future land use, etc.)
A majority of the Working Pad Surface of AL 4 is within Rule 1202.c. Aquatic Sportfish
Management Waters associated with Clear Creek and Deer Park Gulch. In addition, AL 4 is within
Rule 1202.d. Elk Winter Concentration and Elk Severe Winter Range habitats. AL 4 would be
brand new disturbance to accommodate two (2) horizontal wells, associated production
89
equipment, and access road. There are zero RBUs, HOBUs, Schools, School Facilities, or Child
Care Centers within 2,000 feet of the Working Pad Surface of AL 4.
Permitting Considerations:
Chevron is required to submit an OGDP with the ECMC to permit two (2) horizontal wells and
associated production equipment with the new disturbance associated with AL 4. The Relevant
Local Government for AL 4 is Garfield County. Based on the presence of High Priority Habitat
and the location being immediately upgradient of a riparian corridor, AL 4 would trigger an ALA
review. Per Garfield County oil and gas code, if an ALA is completed as part of an oil and gas
application it is to be reviewed at the Garfield County Pre-Application Meeting. Chevron intends
to submit the application for a Garfield County Oil and Gas Permit concurrently with the OGDP
application. AL 4 is located within an income-based DIC designation according to CDPHE’s
EnviroScreen. Although the Well Pad is within a DIC, the Working Pad Surface is not within 2,000
feet of any RBU, HOBU, or School Facility.
Summary:
There’s opportunity for a greater portion of the Working Pad Surface associated with AL 4 to be
outside of Rule 1202.c. Aquatic Sportfish Management Area as compared to the recommended
Well Pad. AL 4 would have similar opportunity to develop the target minerals compared to the
recommended Well Pad and both locations are within the same DIC designation. The main
disadvantage of AL 4 as compared to the recommended Well Pad is that AL 4 is brand new
surface disturbance that would disrupt future agricultural production and livestock grazing. In
addition, based on Chevron observations as surface owner, the lower lying area associated with
AL 4 is a more frequented area for elk habitat given the proximity to Clear Creek than the
recommended Well Pad. For those reasons, the Well Pad is recommended for the proposed
development ahead of AL 4.

ALTERNATIVE OIL AND GAS LOCATION #5 (“AL 5”)
Legal: Township 6 South, Range 98 West, 6th P.M., Section 9
Location ID: 336050
Tier: TIER IV-B
AL 5 is an existing oil and gas location (Location ID 336050) that has twenty-four (24) producing
wells and associated production equipment. AL 5 has gone through the interim reclamation and
recontouring process and has been reduced from the original pad size to approximately 2.5 acres.
In order to utilize AL 5 for the additional two (2) horizontal wells, the pad would need to be re-
expanded with at least another three (3) acres of surface disturbance in addition to the interim
reclamation footprint. The existing footprint of AL 5 is relatively flat, but previous (and any future)
expansion would require construction cuts into the existing terrain in order to not encroach on
Weiss Creek, which is the nearest surface water approximately 46 feet to the southeast. Chevron
is the surface owner where AL 5 is located.
Advantages:
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 5 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 5 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 5 is greater than 2,000 feet from a jurisdictional boundary.
• AL 5 is an existing oil and gas location.
• A majority of the expansion required for AL 5 would be outside of Rule 1202.c. NSO.
• AL 5 has existing gas and fluid infrastructure.
• AL 5 has adequate access for additional operations.
• The data collection for the deeper, non-oil and gas producing formations will be more
easily accessible when starting from the lower-lying valley area associated with AL 5.
Disadvantages:
• A portion of AL 5 is within Rule 1202.c. Aquatic Sportfish Management Waters NSO.
• AL 5 is within Rule 1202.d. Elk Severe Winter Range and Elk Winter Concentration density
habitats.
• AL 5 is immediately upgradient of a riparian area.
• This location is within a Disproportionately Impacted Community.
• Approximately three (3) additional acres of surface disturbance would need to be added
to the current interim reclamation footprint due to existing infrastructure.
• AL 5 would not be adequate for developing the full scope of targeted minerals associated
with the proposed unit. The unit would need to be revised significantly if AL 5 were to be
utilized.
• The nearest surface water is Wiess Creek which is approximately 46 feet from AL 5.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
current and future land use, etc.)
A majority of the Working Pad Surface of AL 5 is within Rule 1202.c. Aquatic Sportfish
Management Waters associated with Weiss Creek. In addition, AL 5 is within Rule 1202.d. Elk
91
Winter Concentration and Elk Severe Winter Range habitats. AL 5 would add two (2) horizontal
wells and associated production equipment to an existing oil and gas location that’s currently
producing. There are zero RBUs, HOBUs, Schools, School Facilities, or Child Care Centers
within 2,000 feet of the Working Pad Surface of AL 5.
Permitting Considerations:
Chevron is required to submit an OGDP with the ECMC to permit two (2) horizontal wells and
associated production equipment to the existing oil and gas location. The Relevant Local
Government for AL 5 is Garfield County. Based on the presence of High Priority Habitat and the
location being immediately upgradient of a riparian corridor, AL 5 would trigger an ALA review.
Per Garfield County oil and gas code, if an ALA is completed as part of an oil and gas application
it is to be reviewed at the Garfield County Pre-Application Meeting. Chevron intends to submit
the application for a Garfield County Oil and Gas Permit concurrently with the OGDP application.
AL 5 is located within an income-based DIC designation according to CDPHE’s EnviroScreen.
Although the Well Pad is within a DIC, the Working Pad Surface is not within 2,000 feet of any
RBU, HOBU, or School Facility.
Summary:
The ALA criteria attributed to AL 5 is very similar to the recommended Well Pad. Both locations
are within Rule 1202.c. Aquatic Sportfish Management Area, Rule 1202.d. Elk Severe Winter
Range, and Rule 1202.d. Elk Winter Concentration. In addition, AL 5 is an existing oil and gas
location, is accessible to existing gas infrastructure, and within the same DIC block group as the
recommended Well Pad. The main disadvantages of AL 5 are the approximately three (3) acres
of surface disturbance that would need to be added to the current interim reclamation footprint,
and AL 5 would not be adequate for developing the full scope of the target minerals associated
with the proposed unit. For these reasons, the Well Pad is recommended over AL 5.

ALTERNATIVE OIL AND GAS LOCATION #6 (“AL 6”)
Legal: Township 5 South, Range 98 West, 6th P.M., Section 36
Location ID: 336055
Tier: TIER III-B
AL 6 is an existing oil and gas location (Location ID 336055) that has twenty-two (22) producing
wells and associated production equipment. AL 6 has gone through the interim reclamation and
recontouring process and has been reduced from the original pad size to approximately 3.4 acres.
In order to utilize AL 6 for the additional two (2) horizontal wells, the pad would need to be
expanded with at least another two (2) acres of surface disturbance in addition to the interim
reclamation footprint. The existing footprint of AL 6 is at an elevated position that doesn’t allow
for easy expansion. The most likely scenario would require a significant construction cut into
steep terrain to add additional Working Pad Surface to AL 6. A portion of AL 6 overlaps the
nearest surface water to the southeast. Chevron is the surface owner where AL 6 is located.
Advantages:
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 6 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 6 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 6 is greater than 2,000 feet from a jurisdictional boundary.
• AL 6 is an existing oil and gas location.
• AL 6 is outside of Rule 1202.c. NSO areas.
• AL 6 is outside of Rule 1202.d. Greater Sage Grouse Priority Habitat Management and
Greater Sage Grouse General Habitat Management areas.
• AL 6 has existing gas infrastructure.
• AL 6 has adequate access for additional operations.
Disadvantages:
• AL 6 is within Rule 1202.d. Elk Severe Winter Range and Elk Winter Concentration density
habitats.
• This location is within a Disproportionately Impacted Community.
• Approximately two (2) additional acres of surface disturbance would be required to be
constructed out of surrounding terrain due to existing infrastructure and surface pad
limitations.
• Although the access to AL 6 is adequate for operations, the road is steep and potentially
limiting during certain winter periods or weather events.
• AL 6 would not be adequate for developing the full scope of targeted minerals associated
with the proposed unit. The unit would need to be revised significantly if AL 6 were to be
utilized. Drilling step-out capabilities is a limiting factor for AL 6.
• AL 6 overlaps the nearest surface water, which is an unnamed surface feature.
• The data collection for the deeper, non-oil and gas producing formations will be more
expensive when starting from the top of the bluff.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
93
current and future land use, etc.)
AL 6 is within Rule 1202.d. Elk Winter Concentration and Elk Severe Winter Range habitats. AL
6 would add two (2) horizontal wells and associated production equipment to an existing oil and
gas location that’s currently producing. There are zero RBUs, HOBUs, Schools, School Facilities,
or Child Care Centers within 2,000 feet of the Working Pad Surface of AL 6.
Permitting Considerations:
Chevron is required to submit an OGDP with the ECMC to permit two (2) horizontal wells and
associated production equipment to the existing oil and gas location. The Relevant Local
Government for AL 6 is Garfield County. Based on the presence of High Priority Habitat, AL 6
would trigger an ALA review. Per Garfield County oil and gas code, if an ALA is completed as
part of an oil and gas application it is to be reviewed at the Garfield County Pre-Application
Meeting. Chevron intends to submit the application for a Garfield County Oil and Gas Permit
concurrently with the OGDP application. AL 6 is located within an income-based DIC designation
according to CDPHE’s EnviroScreen. Although the Well Pad is within a DIC, the Working Pad
Surface is not within 2,000 feet of any RBU, HOBU, or School Facility.
Summary:
AL 6 has the benefit of being fully outside of Rule 1202.c. Aquatic Sportfish Management Area
and has existing gas and fluid infrastructure to the location as compared to the recommended
Well Pad. Both locations are existing surface disturbance within Rule 1202.d. Elk Severe Winter
Range, Rule 1202.d. Elk Winter Concentration, and within the same DIC block group. The main
disadvantages of AL 6 are the approximately two (2) acres of surface disturbance that would need
to be added to the current interim reclamation footprint, and AL 6 would not be adequate for
developing the full scope of the target minerals associated with the proposed unit. For these
reasons, the Well Pad is recommended over AL 6.

ALTERNATIVE OIL AND GAS LOCATION #7 (“AL 7”)
Legal: Township 5 South, Range 98 West, 6th P.M., Section 31
Location ID: N/A
Tier: TIER III-B
AL 7 is brand new surface disturbance unaffiliated with any legacy ECMC Location ID. AL 7 is
on top of a bluff in undisturbed, native vegetation on the northeastern corner of the proposed unit
boundary. There’s an existing access road related to TEP Rocky Mountain LLC operations
associated with Location ID 335608, but from there an additional 2.45-mile road along a
previously reclaimed pipeline right-of-way, existing two-tract road, and new road construction
would be required to get to AL 7. The additional road improvements would create approximately
8.9 acres of surface disturbance in addition to the new surface disturbance associated with the
AL 7 well and facility pad. The nearest surface water to AL 7 is approximately 76 feet to the
northwest. Chevron is the surface owner where AL 7 is located.
Advantages:
• There are zero RBUs or HOBUs within 2,000 feet of the Working Pad Surface.
• AL 7 is greater than 2,000 feet from a School, School Facility, or Child Care Center.
• AL 7 is greater than 1,500 feet from a Designated Outside Activity Area.
• AL 7 is greater than 2,000 feet from a jurisdictional boundary.
• AL 7 is outside of Rule 1202.c. NSO areas.
• AL 7 is outside of Rule 1202.d. Elk Severe Winter Range and Elk Winter Concentration
density habitats.
• AL 7 is adequate for developing the targeted minerals associated with the proposed unit
based on drilling step-out capabilities.
Disadvantages:
• AL 7 is within Rule 1202.d. Greater Sage Grouse Priority Habitat Management and
Greater Sage Grouse General Habitat Management areas.
• This location is within a Disproportionately Impacted Community.
• AL 7 would require approximately 8.9 acres of access road construction in addition to
the new surface disturbance associated with the well pad and facility.
• Access is not possible from Clear Creek Road on West side; access would come from the
East side access from Garden Gulch Road requiring 15 miles and stretches of road
expansion needed.
• There would be additional construction costs associated with the more dramatic
topography on top of the bluffs.
• There’s no existing gas or fluid infrastructure to this location.
• The remote access to AL 7 is potentially limiting during certain winter periods or weather
events.
• The data collection for the deeper, non-oil and gas producing formations will be more
expensive when starting from the top of the bluff.
Potential Impacts to health, safety, welfare, wildlife, and the environment: (Proximity to
floodplains, wetlands, Surface Water Supply Areas (as defined in Rule 411.a.(1)), wildlife,
distance to BUs, BU ownership, right to construct, disproportionately impacted community (“DIC”),
95
current and future land use, etc.)
AL 7 is within Rule 1202.d. Greater Sage Grouse Priority Habitat Management and Greater Sage
Grouse General Habitat Management areas. AL 7 would be brand new surface disturbance to
accommodate two (2) horizontal wells, associated production equipment, and access road. There
are zero RBUs, HOBUs, Schools, School Facilities, or Child Care Centers within 2,000 feet of the
Working Pad Surface of AL 7.
Permitting Considerations:
Chevron is required to submit an OGDP with the ECMC to permit two (2) horizontal wells and
associated production equipment with the new disturbance associated with AL 7. The Relevant
Local Government for AL 7 is Garfield County. Based on the presence of High Priority Habitat,
AL 7 would trigger an ALA review. Per Garfield County oil and gas code, if an ALA is completed
as part of an oil and gas application it is to be reviewed at the Garfield County Pre-Application
Meeting. Chevron intends to submit the application for a Garfield County Oil and Gas Permit
concurrently with the OGDP application. AL 7 is located within an income-based DIC designation
according to CDPHE’s EnviroScreen. Although the Well Pad is within a DIC, the Working Pad
Surface is not within 2,000 feet of any RBU, HOBU, or School Facility.
Summary:
AL 7 has the benefit of being fully outside of Rule 1202.c. Aquatic Sportfish Management Area,
Rule 1202.d. Elk Severe Winter Range, and Rule 1202.d. Elk Winter Concentration as compared
to the recommended Well Pad. AL 7 would have similar opportunity to develop the target minerals
compared to the recommended Well Pad and both locations are within the same DIC block group.
However, AL 7 is within Rule 1202.d. Greater Sage Grouse General Habitat Area and Greater
Sage Grouse Priority Habitat Area. AL 7 would be brand new surface disturbance that would
require approximately 8.9 acres of new access road in addition to the new surface disturbance
associated with the Working Pad Surface. The location of AL 7 on top of the bluff will also require
significantly increased travel distances and associated dust and other emissions and potential
impact to wildlife. The ALA criteria of being new surface disturbance in Greater Sage Grouse
Priority Habitat Area and the need for both gas and fluid pipeline infrastructure to be constructed
to AL 7 is the reason the Well Pad is recommended for the proposed development.
