1/30/2026 | On occasion, the use of additional or alternative lighting sources may be
required for site security or when field conditions experience a significant
alteration. These events would include unpredictable situations, such as
emergency repairs or newly identified hazards. If such changes occur,
light measurements may be conducted at the nearest RBU(s) to ensure
compliance. If it is determined that the measured light level exceeds
standards, additional BMPs will be implemented to the site lighting to
achieve compliance. These changes may include removing or replacing
light sources, repositioning equipment on location, or installing additional
sound walls.
PDC will conduct construction, flowback, and reclamation activities only
during daylight hours to maximize the use of natural lighting. In addition,
there will be no permanent lighting installed on the location during the
production phase.
PDC will conduct regular walkthroughs of the location to ensure no wildlife
have built nests in or around lighting sources. If nests are found, direction
will be issued to either remove the nest or temporarily disable the lighting
source until the nest is abandoned.
PDC will deactivate lighting when not needed using timers or motion
sensors.
PDC will regularly identify permanent and temporary housing of resident
wildlife and ensure locations are recorded in wildlife reports kept in-house.
PDC will schedule regular production activities during daylight hours to
maximize the use of natural lighting.
PDC will use full cut-off lighting to minimize light pollution and obtrusive
lighting.
PDC will use lighting colors that reduce light intensity, including using
neutral white lights.
PDC will use low-glare or no-glare lighting that utilizes high-mount,
narrow-beam angle settings and will direct lighting downwards and
towards the interior of the location.
Should any RBUs along the haul route be impacted negatively by noise or
lighting, PDC will deploy temporary hay bales or barriers around the
structures or roadways. |

Any encroachment of wetlands or active water ways potentially considered
Waters of the United States (WOTUS) will be reviewed and/or protected
under USACE Nationwide or General Permit processes.
PDC will utilize bore techniques for flowline installation under the Eaton
Draw channel and OHWM. Bore points will be a minimum of 500 feet
outside of the OHWM for Eaton Draw and appropriate stormwater controls
will be utilized at each bore point to prevent any mud breakout or material
migration toward the Eaton Draw.
PDC will commit to perform boring activity during non-flowing seasons
for Eaton Draw.
The flowline will be quickly excavated, installed, reclaimed, and
reseeded to prevent any barrier to wildlife movement.
Flowline activities will be inspected daily during installation/construction
operations.

installation activities. |
| Storm Water/Erosion Control | Form: (02A )
404148227
1/30/2026 | Vehicle traffic controls such as rock stabilized construction exits, trackout
control mats, or cattle guards will be located on-site near location exits to
prevent offsite tracking of soils. The type of control measure will depend
on local availability, landowner request, and location specific needs. Any
sediment tracked off-site will be swept or scraped from roadways and
returned to the construction site by the end of each workday. No sediment
will be washed, shoveled, or swept into any roadside ditch, storm sewer,
or surface waterbody. Controls will be maintained throughout the life of the
location.
A berm will be constructed around the location to divert run-on and convey
run-off to the detention basin.
At landowner request, Pads will be fenced to limit access to cattle and
unauthorized travel. Fencing should include cattle guards (which may also
serve as tracking controls).
Temporary seeding, hydro mulching, and/or surface roughening will be
conducted along the ditches, detention pond, and stockpiled soils during
initial construction and maintained until interim reclamation. Additional soil
stabilization and seeding activities will occur during interim reclamation, to
ensure vegetative coverage and prevent erosion.
The detention pond will include an emergency spillway. Riprap will be
installed on the outlet side of both the emergency spillway and the
detention pond discharge pipe.
As part of interim reclamation, a berm will be constructed around the final
disturbance of the location, and the detention pond, stockpiles, and
reclaimed areas will be stabilized with seeding, hydromulching, and/or
surface roughening. |
| Material Handling and Spill Prevention | Form: (02A )
404148227
1/30/2026 | The surface of the location will be plated with 3-5 inches of compacted
road base aggregate that will deter releases from easily seeping into the
soil.
During drilling and completions operations, a temporary impermeable
layer will be utilized under equipment to provide an additional layer of
protection against spills. This layer will include cement-modified soils
under the drill rig and around wellheads. A synthetic liner will be placed
under tank farms, trucks, trailers, and chemical storage.
Secondary containment devices, such as duck ponds or equivalent type
products, will be used to protect soils under any pipe connections or
equipment that carry, mix, or could possibly leak fluids or chemicals.
Audible, Visual, and Olfactory (AVO) inspections of the facility will be
conducted regularly by PDC Energy. Any valve or fitting that is found to be
ineffective will be repaired immediately, or well shut-in procedures will be
implemented.
The location will utilize SCADA and be equipped with remote monitoring
and shut-in capabilities.
All flowlines will be designed/constructed/tested to ASME B31.4 and API
1104 standards. Only materials with Material Test Reports (MTRs)
provided by the pipeline supplier will be used in the construction of the
flowlines.
Spill prevention and response will continue to be addressed in training of
employees and contractor personnel on at least an annual basis.
During pre-production activities, the location will be constructed with
perimeter berms and sloped towards a detention pond to prevent offsite
migration of sediment or contaminants into nearby surface water features.
The berms will help contain a potential on-site release and prevent
contamination of un-plated soil. |
| Dust control | Form: (02A )
404148227
1/30/2026 | All secondary roads created for this project (non-public roadways) will be
finished with ½” – ¾” crushed stone road base.
All soil piles created by construction activities will be managed utilizing
Hydro-mulch, straw crimping, and/or tracking methods to prevent dust
from exiting the location and creating a hazard during pre-production
activities. Soil piles will be graded and/or seeded to prevent erosion and
the generation of dust post-production.
PDC will avoid the creation of fugitive dust by restricting or limiting
construction activity during high wind days.
PDC will maintain safety data sheets (“SDS”) for any chemical-based dust
suppressant and make the SDS immediately available upon request to the
ECMC Director, Weld County, and to any other Local Government or
Agency. Safety Data Sheet(s) for any chemical-based dust suppressant
will be archived and maintained until the site passes final site Reclamation
and transfer the records upon transfer of property ownership.
PDC will minimize the amount of fugitive dust using speed restrictions. All
vehicles will be subject to a speed limit of 20 MPH on all lease roads to
minimize dust.
PDC will mitigate the creation of fugitive dust through regular road
maintenance as coordinated through agreements with Weld County and
any Relevant Local Governments or Agencies with road jurisdiction.
PDC will use methods including wind breaks and barriers, road or facility
surfacing, and soil stockpile stabilization measures to suppress fugitive
dust caused solely by wind.
Prior to the application of dust suppressant to any county or public roads,
coordination will be conducted with Weld County Department of Public
Works by PDC and any relevant vendors.
Silica dust from handling sand used in hydraulic fracturing operations will
be mitigated by utilization of the enclosed Sand Box delivery systems. As
such, no pneumatic transportation of sand will be conducted at this
location.
Vehicle traffic controls such as rock stabilized construction exits, track out
control mats, or cattle guards will be located on-site near location exits to
paved roads to prevent offsite tracking of soils. The type of control
measure will depend on local availability, landowner request, and location
specific needs. Any sediment tracked off-site will be swept or scraped from
roadways and returned to the construction site by the end of each
workday. No sediment will be washed, shoveled, or swept into any
roadside ditch, storm sewer, or surface waterbody. Controls will be
maintained throughout the life of the location.
The access road will be monitored daily during active operations. In
addition, Stormwater inspections will regularly inspect and document the
access road conditions. The Stormwater inspections will follow the
frequency detailed in the Stormwater Management Plan attached to the
Form 2A. During all phases of operations, maintenance will be conducted
as needed to ensure safety and prevent erosion.
All vendors will be required to enact the following when suppressing dust:
Use only fresh water sources (non-potable) when watering areas within
300 feet of the ordinary high-water mark of any water body; Maintain a
current Safety Data Sheet (SDS) in their company vehicle when using a
dust suppressor containing chemicals, in accordance with OSHA Standard
29 CFR 1910.1200 (Hazard Communication) as well as local and State
requirements; Ensure watering practices are not creating additional
hazards on access roads (slick roads, muddy conditions, etc.).
PDC will not use any of the following fluids for dust suppression: Produced
water; E&P waste or hazardous waste; Crude oil or any oil specifically
designed for road maintenance; Chemical solvents; Process fluids.
Based on regional climate observations, there is a high likelihood of
continued dry conditions and the potential for high winds during
construction operations. As a result, PDC will ensure that additional
storage of water and water dispersing equipment, such as water cannons
or water trucks, are staged at the location to be immediately available to
mitigate dust related to construction.
PDC will take all necessary and reasonable precautions to ensure that
dust from the Oil and Gas Location does not unnecessarily impact the
health, safety, and welfare of Wildlife occupying any High Priority Habitat
within 2,000 feet of the Oil and Gas Location. These actions include:
Identify permanent and temporary housing of resident wildlife and ensure
locations are recorded in wildlife reports kept in-house by HSE. Conduct a
daily walkthrough of the location during ongoing operations to ensure no
wildlife have built nest(s) in/around equipment. If nest(s) are found, HSE
reporting will be issued to appropriate personnel to either remove the nest
and/or temporarily abandon the equipment until nest is abandoned.
Access road(s) will be watered or treated with one of the following
commercial dust suppressants, as needed: Roadsaver (magnesium
chloride); Roadsaver Compaction Aid (magnesium chloride); DuraBlend
(magnesium chloride).
Construction of the access road will be conducted by stripping topsoil,
grading and compacting the residual soil, then setting road base. As WCR
39 is a paved roadway, the first 300’ of the access road will be capped
with recycled asphalt. |

404148227
1/30/2026 | Heavy equipment tracking over soil stockpiles will be minimized to avoid
soil compaction.
Long term stockpiles will be stabilized by seeding soils and establishing
vegetation. Typically seeding is performed mechanically, but hydroseeding
may be used for unstable soils.
Microbial activity within stockpiles will be maintained by preventing erosion
with short term stabilization methods, incorporating amendments into soils
prior to seeding, maintaining soil moisture with mulching application, and
establishing vegetation quickly after disturbance.
PDC will monitor the site for the presence of noxious weeds. If
encountered, PDC will employ a third-party consultant knowledgeable in
identifying such species and implement weed control measures consistent
and in compliance with the Colorado Noxious Weed Act. Management will
be performed by either mowing or spraying and in some rare occasions,
both methods may be necessary. Any spraying conducted will be
coordinated with the landowner.
Short term stockpile stabilization methods will include spraying stockpiles
with water to reduce wind erosion, implementing surface roughening, and
utilizing straw mulch as erosion and moisture controls. Hydro mulch may
be applied on unstable soils.
Stockpiled soils will not exceed a 03:01 slope or 10 feet in height.
The seed mixture will be selected in accordance with the ECMC 1000
series rules, and PDC will sow the soil stockpiles with a seed mixture
approved by the surface owner.
Topsoil stockpiles will be marked with a labeled fiberglass marker post or
equivalent sign.
During construction, excavated topsoil will be segregated, stored, and
stabilized on the west side(s) of the oil and gas location for use in
subsequent reclamation. Unused stockpiles will be moved to the east
side(s) of the location for long term stabilization after interim reclamation.
The construction layout for the location has been designed in a way that a
potential spill on location would drain towards the detention pond and
avoid impacting topsoil stockpiles. |
| Noise mitigation | Form: (02A )
404148227
1/30/2026 | If the drilling rig or completions fleet is changed prior to commencement of
operations, the mitigation measures employed will be equally or more
protective.
PDC will post contact information to receive and address noise complaints
arising from preproduction operations around the clock, 24 hours, 7 days
per week. Upon receipt of a complaint, either directly to PDC or from the
Colorado ECMC, or from Weld County, a PDC representative will contact
the associated stakeholder within 48 hours of receipt.
PDC will utilize a low noise completions fleet for all completions
operations.
Flowback operations and equipment were reviewed as part of each
Location’s NMP. The wells will flow back directly to a nearby permanent
facility at a different location away from the Pad location. Perimeter sound
walls will be left in place until drill out is complete and flows are initiated to
appropriately manage noise levels for this operation.
Prior to commencement of drilling and completion activities, a fullperimeter,
engineered sound wall consisting of approximately 2,540 linear
feet of 32-foot-tall, STC32 wall will be installed around the edge of the well
pad to reduce noise levels in the surrounding area.
Throughout the duration of preproduction operations and any construction
lasting longer than 24-hours, PDC will conduct continuous noise
monitoring at the monitoring locations described in Figure 10 of Section 9
of the Monson Pad’s Noise Mitigation Plan. |
| Interim Reclamation | Form: (02A )
404148227
1/30/2026 | Topsoil salvaged and stabilized during construction will be utilized for
interim reclamation, layered on top of any subsoil, and packed separately
and sequentially. The area will be graded and recontoured to predisturbance
conditions with elevations and slopes suitable for runoff
control.
PDC will cross-rip compacted soils to 18 inches in depth using a parabolic
Ag style ripper to enhance water infiltration and promote vegetation
growth. Cross-ripping of lands to be returned to crop land will be
undertaken when soil moisture is below 35% of field capacity.
Seedbed preparation is anticipated to include tilling and discing
compost/manure into the top 3-4 inches of soil to ensure vegetation
establishment occurs after seeding.
During interim reclamation, seeding will be performed at all areas not
required for future production operations, and it will be conducted during a
spring or fall planting window to achieve maximum germination rates.
Areas to be reclaimed will be seeded in accordance with the landowner’s
preference or based on consultation with the local soil conservation
district. PDC will coordinate all seeding activities with the landowner to
ensure compatibility with future land use. The landowner will seed areas
returned to crop land.
In addition to seeding, straw crimping is anticipated to be used to stabilize
reclaimed areas. Hydroseeding may be required if the soils are
determined to be too unstable.
PDC may install temporary fencing to ensure vegetation is not overgrazed.
All fencing will be coordinated with the landowner.
In accordance with the ECMC Rule 1003.f and the Colorado Noxious
Weed Act, invasive plants will be monitored throughout all phases of
construction during routine stormwater inspections. Inspections will
identify and inventory any/all invasive plants on the location. Management
will be performed by either mowing or spraying and in some rare
occasions both methods may be necessary. Weed infestations may
require consultations with local weed control agencies.
PDC will schedule routine inspections to monitor reclamation progress and
site conditions. ECMC requires plant cover to be returned to at least eighty
percent of pre-disturbance levels for interim reclamation to be considered
complete. |
