1/23/2012 | Describe in detail the pollution control BMPs for the site based on possible pollutants. Show these
pollution control features on the sketch. Describe when and where the BMPs will be implemented.
• The interior perimeter vee ditch and berm wall will prevent the escape of any fugitive pollutants from
the leaving the construction area.
• The diesel fuel storage for the rig is contained within a steel tank with a ditch constructed around the
perimeter of the fuel tank to capture any leaking fuel.
• Vehicular traffic entering and leaving the site during storm events will have their tires and
undercarriage washed down at the entrance to the existing lease road off of WCR # 6.
Describe the maintenance schedule developed for the site: Storm water BMPs will be inspected on a
frequent basis to assure their integrity and repaired within 24 hours of any inspection. The site will be
inspected every 14 days and after each significant storm event.
If the construction of the site is to be accomplished by more than one operating group, identify the
operating group that will subsequently take over the site: The same operating group will conduct all
construction tasks. |

SUPPLEMENT FORM
Describe how the reclamation of the site is to be accomplished:
If the site is located in a cultivated field, the site will be:
1. cross ripped to minimize compaction.
2. rough graded back to the original contours.
3. released to the surface owner /tenant for cultivation
If the site is located in a non - cultivated field, the site will be:
1. cross ripped to minimize compaction.
2. rough graded back to the original contours.
3. cross disced to prepare the site for seeding.
4. grass seed will be drilled into the seedbed at prescribed rates.
5. wheat straw will be crimped into the seedbed for erosion control.
6. Silt fencing or other erosion control structures will remain in place until the seedbed is 70 To
revegetated. |

Site/Job Name: Alaux Well pad Project Location: From the intersection of the I - 25 east frontage
Road and WCR # 6, east 1 /4 mile to lease road and south to location (existing well head).
Qtr: NENE /4 Section : 26 Township: 1N Range: 68 W County: Broomfield
Prepared by: Cliff Roberts Date: July 27, 2009
Date of Site Inspection : July 24, 2009
Current Site Conditions : Dry Land Wheat
Past land use : agriculture Existing Topography : < 2 To slopes
Are Wetlands present on or near the property? No
Will the proposed construction affect on -site wetlands? No
Soil Types: clayey loam
State receiving Water : n/a
Route of stormwater leaving the site : Stormwater will be prevented from entering the site by the barrier use
of a vee ditch and berm wall constructed on the four sided perimeter of the site. Storm water will be
prevented from leaving the site by the same barriers described above.
Are there any defined drainage channels or structures on site ? No
Attach to this form a simple sketch of the site outlining the construction. Include: construction site boundaries; areas of ground
disturbance; areas of cut and fill; areas used for storage of equipment, soils, waste, or chemicals; locations of all structural and non-
structural BMPs; any ditches , canals, creeks, streams and rivers located within 1 /4 mile of the site; and any other pertinent information.
Determine the direction of the drainage or flow gradient for the site. Identify this flow gradient with a simple arrow pointing in the
direction of the flow.

Erosion Potential: Erosion potential is estimated to be minimal due to the shallow surface grade site.
Describe in detail the erosion control BMPs adopted for the site based on a study of the site and the general
topography of the area. Show these erosion control features on the sketch.
• If a pitless location, there will be no soil stockpiles.
• If a reserve pit is used, soil stockpiles will tracked to compact and minimize.
• A combination Vee ditch and berm wall will be constructed around the interior perimeter of the well
pad.
Possible pollutants include the following: ground surface disturbing activities, soil stockpiles, dust or
particulate generating activities, trash dumpster, portable toilets, vehicle tracking. Portable toilets and trash
dumpsters are serviced on a scheduled basis.
Determine the potential of the above applicable pollution sources to impact storm water discharge: The
potential of the above named pollutants to impact storm water is minimal due the presence of the named
BMPs and the shallow topography of the construction site and surrounding area. |
