traffic on graveled access roads hecomes significant, dust suppression procedures will be
implemented that include road watering or the application of dust suppressants.
4.3.3 On-site Waste Disposal Practices
All waste from materials imported to the construction site are removed for disposal/recycling to
an appropriate licensed disposal/recycling facility. This also includes sanitary sewage facilities
(typically portable). No waste materials shall be buried, dumped, or discharged to waters of the
State.
4.3.4 On-site Pad Activities
The most common substances that may be spilled on a pad area are; I) fuel and lubricants used
by vehicles and construction equipment; 2) frac fluids (surfactants, friction reducers,
hydrochloric acid, and potassium chloride) used during well completion procedures; 3)
production water from the well: and 4) produced crude oil and condensates.
4.3.5 otT-site Soil Tracking Controls
Properly constructed and graveled roads and pads provide the best off-site tracking control.
Access road entrances adjacent to paved county roads are often graveled to prevent or minimize
any off-site soil tracking from pad areas or access roads .
4.4 Receiving Waters
Drainages within Area I include: the South Platte River, Big Thompson River, SI. Vrain Creek,
Cache la Poudre River, and Boyd Lake. The drainage for each pad is entered on each site
specific inspection form.
4.5 Runoff Coefficient
Runoff coefficients for pad locations within Area I vary from O. I 0 to 0.30 and are not expected
to significantly change. Pad areas range from flat rangeland to hilly areas.
5.0 BEST MANAGEMENT PRACTICES
5.1 Material Handling and Spill Prevention
Hazardous materials and petroleum products used in construction of a pad include fuel and
lubricants for construction equipment and vehicles; small quantities of paints and solvents; water
or gel based frac fluids (surfactant, friction reducer, dilute hydrochloric acid, potassium chloride)
used during well completion; produced water; and, crude oil/condensate. Material Safety Data
Sheets (MSDS) tor materials to be used or that are produced are filed at Kerr-McGee's Denver
Office.
Refueling and lubrication of vehicles and equipment will he conducted a minimum of 100 feet
from flowing streams and wetlands. Any spills will be promptly remediated and contaminated |

1/23/2012 | 4.0 SITE DESCRIPTION
4.1 Project Overview
Kerr-McGee currently owns or leases natural gas mineral rights in the Wattenberg Field area
which includes Adams, Boulder, Broomfield, Denver, Larimer and Weld Counties, Colorado.
Kerr-McGee has split the field into three project areas for operations management purposes. A
map of the project area (Area I within the Wattenberg Field) is provided as Figure I.
The development of natural gas wells is generally accomplished in three distinct work phases.
The first phase is the Development (construction/drilling/completion), the second phase is the
Production (operation/maintenance), and the third phase is the Abandonment with final
reclamation. Each work phase is briefly discussed below.
4.1.1 Development (Construction/DrillinglCompletion/Reclamation) - Active Site
Approximately % to three acres of surface terrain is disturbed during the construction of a new
pad. The Development phase includes the following activities: pad construction, well drilling,
well completion, gas flowline installation, access road building, and pad area reclamation. Pad
reclamation is accomplished by backfilling the reserve pit, contouring disturbed soils to conform
to the surrounding terrain, replacing the stockpiled lOp soil, seeding of disturbed soil areas in
order to reestablish coverage vegetation. The completion of a well (gas production) generally
triggers a one-year time period in which the reclamation phase of work should be completed.
4.1.2 Production (Operation/Maintenancel - Completed Site
The production phase includes the operation and maintenance activities during natural gas
production. The typical equipment on a pad during the production phase consists of a wellhead,
a separation unit, from one to several 300-barrel capacity aboveground tanks for condensate, and
a sump for storing produced water. Reclamation activities during this phase include maintenance
of revegetated areas and maintenance of the erosion and sediment control structures. Natural gas
wells in the field are projected to produce for approximately 20 to 30 years.
4.1.3 Abandonment and Final Reclamation
When the natural gas production of a well is exhausted it will be abandoned. Upon well
abandonment each borehole will be plugged, capped, and all surface equipment will be removed.
Subsurface pipelines will be removed to specified locations and plugged. The pad area will be
reclaimed by contouring disturbed soils to conform to the surrounding terrain, by replacing the
stockpiled top soil, by seeding of disturbed soil areas in order to reestablish cover vegetation, and
by construction of erosion and sediment control structures as needed.
For the purposes of this SWMP and the stormwater construction general permit, only active and
completed sites will be monitored. Once a completed site is revegetated and stable, it will be
removed from this stormwater construction SWMP. |

1/23/2012 | materials will be hauled off-site and disposed of/recycled properly. Quantities of fuel and
lubricates will be limited to "as-needed" for the immediate operations underway.
5.2 Sediment and Erosion Control
Sediment and erosion control will be accomplished through a combination of construction
techniques, vegetation and re-vegetation, and structural features. The book entitled "Field
Manual on Sediment and Erosion Control Best Management Practices for Contractors and
Inspectors" (Field Manual) by Jerald S. Fifield or similar guidance will be referenced for
assistance with controls or BMPs when needed. Typical configurations of structural controls
discussed below and technical drawings are provided in Appendix A.
5.2.1 Erosion Reduction and Control
Construction of a pad requires the removal of vegetative cover and topsoil that increases peak
flood flows, water velocity, and the volume of stormwater runoff. An increase in water runoff
volume and velocity results in increased erosion. Erosion reduction and control will be
accomplished by using the following erosion control methods:
diversion and control of runoff water;
vegetation planting and maintenance; and
• application and maintenance of mulches .
Runoff control procedures that will be used to mitigate and reduce the erosive transport forces of
stormwater during and after construction of a pad will include but will not be limited to the
following:
Check dams;
Earth berms;
Culvert protection;
Diversion dikes;
Conveyance channels;
Slope drains;
Rock-lined ditch;
Mulches; and
Geotextiles . |

1/23/2012 | 5.2.5 Non·Structural Practices
Sediment and erosion control can be implemented via non-structural BMPs. Non-structural
BMPs are BMPs that are not engineered as a stormwater barrier and are capable of limiting the
amount of potential pollutants available to reach receiving water bodies. Non-structural BMPs
can achieve the same effect as structural BMPs through filtration and the settling of sediment
load within a perimeter.
Pad sites can include a buffer zone of natural vegetation used as a non-structuml BMP to inhibit
sediment travel. Appendix B includes a typical pad site figure with the use of a buffer zone as a
BMP.
5.2.6 Pad Preparation
Existing vegetation cover and topsoil will be removed only where necessary for the operation of
equipment and construction of the pad. Trees and large shrubs that are not cleared from the pad
area will be protected from damage during construction by avoiding them with equipment. For
example, the blade of a bulldozer will maintain in a raised position except for areas designated.
Trees will be cut or trimmed only to facilitate clearing, grading, and safe installation of a pad.
Trees outside the area of disturbance will not be cut, but may have overhanging limbs removed
by cutting.
5.2.7 Excavation
Excavated materials will be stored next to the pad in order to construct a flat pad. Topsoil will
be stockpiled in one location and other soils will be stockpiled in a separate and different
location. Excavation in especially sensitive areas may be conducted according to special
techniques as specified by the landowner/agency representative.
Materials excavated will be utilized as backfill when practical. An exception may be excess rock
generated by rock blasting excavates activities. In these areas. some select backfill materials
may be required to protect the project area. Excess rock may be pushed into rock filter dikes,
used in energy dissipation zones below culverts, constructed into rock check dams within grassed
swales, or distributed over a portion of the project area.
All cut slopes made in steep rolling terrain during construction will be re-graded and contoured
to blend into the adjoining landscape and natural drainage patterns will be reestablished.
Temporary workspace areas will be restored to approximate pre-construction conditions.
5.2.8 Streams and Sensitive Areas
The majority of Kerr-McGee 's pad~ or access roads do not intrude or encroach on any wed and
acreage. If a wetland is designated to be within a pad construction area, Kerr-McGee will obtain
permits from Army Corp of Engineers, as appropriate. |

1/23/2012 | Personnel responsible for inspections shall be trained to evaluate stormwater management
concerns, erosion and sediment control structures, and to evaluate pad and surrounding area
vegetation.
7.2.1 14-day Inspection/Active Site (Development Work Phase)
The development work phase includes the construction, drilling, completion, and interim
reclamation of the natural gas wells. This phase of work is classified as the active phase and the
inspection frequency is every 14 days and after any precipitation or snowmelt event that causes
surface erosion.
The pad perimeter, disturbed areas, and any stored materials that are exposed to precipitation will
be inspected for evidence of. or the potential for pollutants that may enter the drainage system.
Erosion and sediment control systems that are identified on the SWMP Inspection and
Maintenance form, which is site specific, will be inspected to ensure that they are in good
condition and operating properly.
7.2.2 Monthly Inspection/Completed Site (Production Work Phase)
After final pad reclamation has been initiated and during the production phase of a pad,
inspections will be conducted at least once a month. This inspection frequency wiJI be continued
until the pad area achieves or reaches final stabilization vegetation conditions, at which time
inspections are discontinued.
7.2.3 Finally Stabilized
When a pad site has reached final stabilization, it will be removed from the storm water
construction inspection routine.
7.2.4 Winter Conditions
Inspections will not be required at pads where snow cover exists over the entire site for an
extended period as long as melting conditions do not exist.
7.2.5 Precipitation Event Inspections
Active pad inspections will be conducted within 24 hours after a precipitation or snowmelt event
that causes surface erosion. Surface erosion generally occurs when precipitation or snowmelt
results in surface water now. If the precipitation infiltrates, then no inspection is
required. In order to determine if surface erosion or surface water now resulted from a
precipitation or snowmelt event. a selected few pads will be evaluated for surface erosion, offsite
sediment transportation, and/or off-site release of muddy water. These selected pads may
have a worst case surface erosion or sediment transportation scenario. If the selected pad and
associated areas do not show any off-site surface erosion, off-site sediment release and transport.
or off-site muddy water releases, all of the remaining active and completed pads will not be
inspected. Inspection results of the pads will determine or trigger the inspection of all active and
completed pads. If a significant number of the pads show off-site surface erosion. off-site
sediment transportation, or release of muddy water then all of the remaining pads will be |

discussed in the sections below. Appendix B contains site-specific information.
4.2.1 Area 1 Topographic Map
A topographic map of the area is provided as Figure I.
4.2.2 Specific Well Site Pad Information/Map
Pad construction site boundaries, soil disturbance areas, wellhead locations on the pad, typical
drill rig layout. chemical storage locations, and maps showing any other pertinent site specifics
are attached in Appendix B. Example base maps of typical pad construction sites have been
included as a reference. Site specific features may be hand-drawn.
4.3 Identification of Potential Pollutant Sources
To identify, evaluate, and assess potential sources of stormwater runoff pollutants that may be at
a pad, the following activities and pollutant sources were evaluated:
Loading and unloading operations;
Significant dust or particulate generating processes;
On-site pad, waste disposal practices;
On-site pad activities:
Off-site soil tracking controls; and
Significant spills or leaks of toxic or hazardous substances.
4.3.1 Loading and Unloading Onerations
The majority of loading and unloading activities occur during well drilling and well completion
activities. Well drilling and completion surfactants, friction reducers. dilute hydrochloric acid.
potassium chloride solutions. drilling mud, and other fluids are transported or unloaded directly
into the well from trucks, on site tanks, and the reserve pit. Dry drilling mud components are
contained in paper bags and are stacked on pallets. which are unloaded using a forklift or by
hand. In the event of a spill, the SWMP material handling and spill prevention procedures will
be followed. Other activities include unloading of drill pipe. completion pipe (casing), and
natural gas line pipe, which are not potential pollution sources.
4.3.2 Dust or Particulate Generating Processes or Activities
An evaluation of dust or particulate generating processes or sources was completed and one
source was identitled that may produce dust and particulates. Dust and/or particulates generated
from vehicle traffic on graveled access roads may produce fugitive emissions. Dust and |

1/23/2012 | Culverts may be installed at a grade ranging from 2-5 percent. Inlet protection may
include inlet aprons and rock armoring around the culvert perimeter while below grade
inlet sumps may be installed to enhance sediment deposition. Outfall protection may
include the use of a rock barrier to slow the discharge of runoff water. Culvert pipe or
outfall protection will be extended to the toe of the slope on the discharge end.
During the reclamation of a pad all cut and fill slopes in steep terrain will be graded and
contoured to blend into the adjoining landscape. Natural drainage patterns will also be
reestablished. When possible cut and fill slopes will be constructed so they are no steeper
than a I to 3 ratio.
Reclaimed pads may have a fence constructed around areas that have been seeded. These
fences will be installed in order to keep livestock and vehicles off reseeded areas.
5.2.4 Implementation of Structural Practices
The following sediment controls may be utilized at pad areas: vegetative filters, brush dams, rock
filter dikes, silt fences, straw bale dikes, water bars, sediment traps, sediment basins, or
equivalent sediment controls. These sediment controls structures will be installed so as to
protect down slope surface waters, wetlands and roads from sediment flow due to runoff from a
precipitation event.
All graded surfaces, walls, dams and structures, vegetation, erosion and sediment control
measures and other protective devices identified in the pad plan will be maintained, repaired, and
restored as necessary. |

1/23/2012 | During construction near perennial streams, lakes or wetlands, the utilization of sedi mentation
(detention) ba~ins, silt fences, straw bales, or fabric filters may be considered in order to prevent
suspended sediments from reaching downgradient watercourses, streams, lakes or wetlands.
Where appropriate water bars or sediment filters, such as staked straw bales or silt fences, will be
constructed adjacent to crossings to reduce potential sedimentation in streams or wetlands.
6.0 FINAL STABILIZATION AND LONG-TERM STORMWATER MANAGEMENT
6.1 Long-term Management
6.1.1 Reclamation
Unless otherwise directed by the landowner or a jurisdictional authority, rocks, cut vegetation,
and other surface material temporarily stockpiled during construction will be redistributed as
backfi II on the project area.
Disturbed areas will be seeded using seed mixes appropriate to the location, unless the
landowner wishes to return the land to agricultural production. Local soil conservation
authorities with the U.S. Natural Resources Conservation Service, surface owners and/or
reclamation contractors familiar with the area may be consulted regarding the correct seed mix to
be utilized.
On terrain where drill seeding is appropriate, seed may be planted using a drill equipped with a
depth regulator to ensure proper depth of planting. The seed mix will be evenly and uniformly
planted over the disturbed area. Drilling will be used where topography and soil conditions
allow operation of equipment to meet the seeding requirements of the species being planted.
Broadcast seeding will occur on steep terrain and on areas where the cut vegetation and rocks
were redistributed over a right-of-way.
Seeding will be done when seasonal or weather conditions are most favorable according to
schedules identit1ed by the jurisdictional authority, reclamation contractor, or landowner.
Whenever possible, seeding will be timed to take advantage of moisture, such as early spring or
late fall, which will benefit from winter precipitation.
Seed mixes will be planted in the amount specified in pounds of pure live seed/acre. No primary
or secondary noxious weeds shall be in the seed mix.
The reestablishment of vegetative cover as well as watershed stabilization measures will be
scheduled during the working season and before the succeeding winter. Re-vegetation will be
accomplished as soon as practical following the reclamation of a pad.
Mulch will be laid down during re-vegetation as appropriate. The cut vegetation and rocks will
act like mulch in the areas where they are applied. Where straw or hay mulch is applied, the
mulch will be applied and crimped into the soil.
The need for fertilizers will be determined in conjunction with the landowner. If fertilization is
• necessary, the rates of application will be based on site-specific requirements of the soil. |

1/23/2012 | A special condition exists for pad sites within crop lands. According to the CDPHE Stormwater
Fact Sheet dated February 3, 2006:
when portions of an oil and gas site are restored to crop land in accordance with
the COGCC rules. and returned to the control of the fanner following interim
reclamation. permit coverage is no longer required for those areas, and it is not
necessa ry for the oil and gas site to either stabilize or reassign pemlit coverage
for the area restored to crop land. Therefore, permit coverage may be inactivated
jiJr an oil and gas collstruction site even if stabilized unpaved surfaces exist
(lnd/or disturbed land that has been restored to crop land remains un vegetated as
long as construction activities have been completed and all other disturbed areas
revegetated in accordance with the definition of Fitull/y Stabilized.
When this condition exists for a pad site, inspections will be discontinued and the site will be
removed from the stonnwater construction pennit program.
6.1.2 Post·Construction Structural Measures
Permanent water bars and trench plugs may be installed on steep slopes and at wetland and
stream crossing boundaries.
After restoration and reclamation work is complete, required repairs to vegetation and erosion
and sediment control structures will be completed as required by routine scheduled inspections
and/or in response to other notifications.
6.1.3 Finally Stabilized
According to stormwater regulations, "finally stabilized means that all disturbed areas have been
either built on, paved, or a uniform vegetative cover has been established with a density of a least
70 percent of pre-disturbance levels and the vegetation cover is capable of providing erosion
control equivalent to pre-existing conditions, or equivalent permanent, physical erosion reduction
methods have been employed."
7.0 INSPECTION AND MAINTENANCE PROCEDURES
7.1 Preventive Maintenance
Preventing stonnwater from passing through pad areas where contamination may occur is a key
element of preventative maintenance. Another key element of preventative maintenance is the
routine inspection and repair of erosion and sediments control structures. Regular cleaning of
diversion ditches to keep them free of debris and sediment will be practiced. Spillways and
culvert systems will also be routinely cleaned and inspected. These maintenance procedures will
help to insure that the stormwater does not leave intended channels.
The following preventive maintenance procedures will be implemented to reduce or eliminate
potential stormwater contamination sources that may exist on a pad: |

Record keeping.
9.0 RECORD KEEPING
The following record keeping procedures will be followed in order to provide accurate and
complete documentation of events associated with the stormwater management program. A
SWMP Inspection and Maintenance Form is located in Appendix B and will be used for all
SWMP inspections. Routine inspections will include the 14-day, monthly, and after a
precipitation event. Storrnwater related inspection records, site maps, and diagrams will be also
kept on file. All stormwater related records will be filed and stored by Kerr-McGee for a
minimum of three years.
10.0 SWMP REVIEW/CHANGES
Kerr-McGee will amend the SWMP whenever there is a significant change in design,
constnlction, operation, or maintenance. which has a significant effect on the potential for the
discharge of pollutants to water of the state, or if the SWMP proves to be ineffective in achieving
the general objectives of controlling pollutants in stormwater discharges associated with pad
activities. |

1/23/2012 | 5.2.2 Sediment Reduction and Control
The control and reduction of sediment contained in stormwater runoff will be accomplished by
the use of sediment containment systems. Sediment containment systems are hydraulic controls
that allow the deposition of suspended particles by gravity. Sediment controls that will be used
to mitigate and control sediments generated from the erosive transport forces of stormwater
during and after construction of a pad will include but will not be limited to the following:
Silt fences;
Bale dikes;
Sediment traps;
Sediment ba~ins;
Vehicle track pads; and
Continuous berms.
5.2.3 Structural Practices
The following structural site management practices are expected to reduce, minimize and control
erosion and sediment transport.
In order to minimize disturbances associated with installation of pads, level and gently
sloping terrain outside the project area will not be graded. except where necessary.
To prevent tracking of sediment (mud and rocks) onto public roads. portions of access
roads may be graveled. as appropriate. Other means such as track pads/angular rock or
cattle guards may be utilized if appropriate.
Silt barriers (e.g. brush dams. rock filter dikes. silt fences. hay bales. or water bars) will
be installed as needed on down-gradient portions of project areas.
Side hill cuts (cut slopes) will be kept to a minimum to protect local resources while
providing a safe and stable plane for the efficient and safe use of equipment.
Where conditions warrant. erosion control structures such as berms, water bars, diversion
or collection channels. terraces, or culverts will be constructed to divert water away from
project areas. These control structures will also reduce soil erosion along and adjoining
areas disturbed during construction.
In areas that have steep slopes. water bars or runoff diversions may be installed.
Guidelines for the spacing of diversion structures are listed below. When used, water
bars will generally begin and end in undisturbed ground at approximately a 2% slope. |

Erosion damage to the earthen berms, outfalls. silt barriers, collection channel.
containment ponds. and any erosion and sediment control will be repaired within seven
days of discovery;
Areas of stained soil will be inspected in order to identify the sources of the staining.
Contaminated soil will be removed and properly disposed;
Energy dissipating material. such as riprap. will be placed at the stormwater outfalls to
prevent erosion damage. Although there may be a number of pads that may not currently
have distinct outfalls. energy-dissipating material such as cobbles or gravel may be used
to minimize erosion due to stormwater. Barrow ditches should be free from vegetation
and debris which may cause impounding of storm water; and
Stormwater management structures will be cleared of debris and repaired when
necessary; and surface runoff controls such as curbing, culverts, and ditches will be used
to control runoff.
7.1.1 Good Housekeeping
In accordance with Best Management Practices that provide procedures to eliminate
contamination; direct, divert, and contain stormwater; Kerr-McGee has implemented a number
of housekeeping practices that will help prevent soil sediment. trash. and toxic or hazardous
substances from entering navigable waters.
Housekeeping practices include regular cleaning. organization and maintenance of pad
equipment and erosion and sediment control structures throughout the project. Areas where
chemicals are stored and used at the project are stored in builclings or containers where there is
no potential for stormwater contact. These areas include producing pads that typically consist of
wellheads, separator units. dehydration units. and 300-barrel capacity aboveground stock tanks.
The following items will be addressed in order to maintain a clean and orderly pad during the
development, production, and abandonment phases of work:
Inspect pad areas routinely;
Correct deficiencies noted during inspections;
Clean and maintain stormwater management structures and components;
Routine trash collection and disposal; |

1/23/2012 | 2.0 INTRODUCTION
On June 30, 2005, the State of Colorado stormwater regulation went into effect to require
Colorado Discharge Permit System (CDPS) permits from the Water Quality Control Division
(WQCD) for stormwater discharges from construction activities associated with small
construction activity for oil and gas sites that disturb between one and five acres. As part of that
requirement, this Stormwater Management Plan (SWMP) has been prepared to identify possible
pollutant sources to stormwater and to set out Best Management Practices (BMPs) to reduce or
elirrrinate possible water quality impacts.
3.0 SWMP TEAM

7.1.2 Material Storage
The following good housekeeping practices will be followed at the material storage areas:
Storage containers will be stored away from direct traffic to prevent accidents. They will
also have proper labels;
Dumpsters and trash receptacles will be enclosed in order to prevent the dissemination of
refuse;
• Storage areas will be kept free of refuse;
Chemical substances used at pads will be properly labeled and will have proper spill
containment; and
Chemical substance containers will be clearly labeled with an MSDS kept on file.
7.1.3 Waste Removal
All waste from materials imported to the construction site will be removed for disposal/recycling
to an appropriate licensed disposal/recycling facility. including sanitary sewage facilities
(typically portable). No wastes of imported materials shall be buried, dumped, or purposely
discharged to waters of the State. There are no other pollutant sources from areas other than
construction areas.
7.2 Inspections
Inspections will be conducted to document the status of erosion and sediment control structures
and re-vegetation efforts. Inspection reports will document non-compliance conditions such a~
uncontrolled releases of mud, muddy water, or measurable quantities of sediment that are found
off-site. Required actions or modifications as documented on the inspection form will be
implemented in a timely manner, and completed within seven calendar days after the inspection.
Routine inspections will be conducted at pad area~ during all phases of work and after a
precipitation-related event. All inspection observations will be recorded on the SWMP
inspection form that is located in this section. The inspection form provides a standardized
format that will be completed during all inspections.
A special condition exists for pad sites within crop lands, which is detailed under the
Reclamation section of this plan. When pad sites are being returned to a farmer for agricultural
usage, and all other disturbed areas have been stabilized or revegetated. the sites may be
removed from the stormwater construction permit program. |

sediment transportation, or release of muddy water) is marked yes. Selection of a pad is based
on the following criteria:
A pad that ha~ a cut or fill slope that has a steeper grade than 1:4
A pad that has erosion and/or sediment control structures installed
A pad that has vegetation or erosion situations
During the inspection of pad areas, associated access road should also be inspected. All culverts
should be inspected to see if any inlet, outlet or other problems exisl. Inlets or outlets to culverts
may have to be cleaned in order to insure proper drainage.
