If historic or archaeological materialsare uncovered during construction, the operator will immediately stop work that mightfurther disturb such materials, and contact the Authorized Officer. Within five workingdays the Authorized Officerwillinform the operator as to:

• Whether the materials appear eligiblefor the National Register of HistoricPlaces;

• The mitigationmeasures the operator will likely have to undertake before thesite can be

O &BIG WASH 62-15GRSurface Use Plan Page 9

• A time frame for the Authorized Officerto complete an expeditedreviewunder36 CFR 800.11 to confirm,through the State Historic Preservation Officer,that the findings of the Authorized Officerare correct and that mitigationisappropriate.

If the operator wished, at any time, to relocate activitiesto avoid the expense ofmitigationand/or the delays associated with this process, the Authorized Officer willassume responsibility for whatever recordation and stabilizationof the exposedmaterials that may be required. Otherwise, the operator willbe responsible formitigationcosts. The Authorized Officerwillprovide technicaland proceduralguidelines for the conduct of mitigation.Upon verification from the Authorized Officerthat required mitigation has been completed, the operator willthen be allowed toresume construction.

B. As operator, EOG Resources, Inc. willcontrol noxious weeds along Right-of-Ways forroads, pipelines, well sites, or other applicable facilities. A list of noxious weeds willbe obtained from the BLMadministered land, a Pesticide Use proposal shall besubmitted, and given approval, prior to the application or herbicides or otherpesticides or possible hazardous chemicals.

C. The drilling rig and ancillaryequipment willbe removed from the location prior tocommencement ofcompletion operations. Completion operations willbe conductedutilizing a completion/workoverrig.

D. Drilling rigs and/or equipment used during drilling operations on this well site willnotbe stacked or stored on BLM lands after the conclusion of drilling operations or at anyother time without BLMauthorization. However, if BLMauthorizationis obtained, it isonlya temporary measure to allowtime to make arrangements for permanent storageon commercial facilities. (The BLMdoes not seek to compete with private industry.There are commercial facilities available for stacking and storing drilling rigs.)

AIIlease and/or unit operations willbe conducted in such a manner that full compliance ismade with all applicable laws, regulations, Onshore Oil and Gas Orders, the approved Planof Operations, and any applicable Notice of Lessees. The operator is fully responsible forthe actions of its subcontractors. A complete copy of the approved "Application for Permit toDrill"and "Right-of-Way grant", if applicable,willbe furnished to the field representative(s) toensure compliance and shallbe on location during all construction and drilling operations.

Construction activitywill not be conducted using frozen or saturated soils material or duringperiods when watershed damage is likely to occur.

Ifthe existing access road, proposed access road, and proposed pad are dry duringconstruction, drilling, and completion activities,water willbe applied to help facilitatecompaction during construction and to minimize soil loss as a result ofwind erosion.

Request for Exception to Buried Pipeline RequirementBIG WASH 62-15GR

SWNE, Sec. 15, T10S, R16EU-64911

EOG Resources, Inc. requests a variance to the requirement for a buried gas sales pipeline for thereferenced well for the following reasons:

1. In order to bury pipe on the gas sales line route, additional surface disturbance relativeto surface pipeline would be approximately 11.75 acres.

2. Ripping, cutting, or blasting of rock would be required, which in turn would leavelong-term spoils on the right-of-way.

3. The disturbed soils on the pipeline corridor would be difficult to rehabilitate andwould be susceptible to noxious weed infestation, which in turn would be hazardousto livestock.

4. Supplemental soil to replace removed rock would need to be hauled in from otherlocations to provide bedding and cover material.

5. The buried pipe would need to be coated and/or wrapped to minimize the potential forcorrosion-caused gas leaks and blowouts.

6. Burying of pipe next to access roads increases the potential for damage, explosion,and fire when using graders and/or dozers for snow removal or road rehabilitation.

7. Surface equipment, including risers with blow down valves and pipeline markers willbe required, adding to negative visual impact.

8. Disturbance of previously rehabilitated pipeline corridor could be necessary ifincreasing well density requires crossing of the corridor or location construction onthe corridor.

9. Pipeline corridors subject to poor rehabilitation characteristics are susceptible to highrates of soil erosion.

10. Buried shallow pipelines in low areas subject to the occasional presence of standingwater are susceptible to movement and

SURFACE USE PROGRAMCONDITIONS OF APPROVAL (COAs)

Site Specific Conditions of Approval:

• During operations, if any vertebrate paleontological resources are discovered, all operationsaffecting such sites shall be immediately suspended, and all discoveries shall be left intact untilauthorized to proceed by the Authorized Officer. The appropriate Authorized Officer of theVernal BLMoffice shall be notifiedwithin 48 hrs of the discovery, and a decision as to thepreferred alternativelcourse of action will be rendered.

• The lesseeloperator is given notice that lands in the lease have been identified as containingRed-Talled Hawk nesting habitat. It is requested that the lesseeloperator not initiate surfacedisturbing activities or drilling from April 1" through July 15th. A survey may be conducted by aqualified biologist or a BLMrepresentative during this timingperiod to determine if hawks are inthe area.

• The lessee/operator is given notice that lands in the lease have been identified as containingcrucial deer and elk winter range. It is requested that the lesseeloperator not initiate surfacedisturbing activities or drilling from December 1" throughApril 30 h. A Survey may be conductedby a qualified biologist or a BLM representative during this timingperiod to determine if deer orelk are in the area.

• As discussed on the onsite conducted on December 12, 2006 the pit will be double felted andpolyswell applied.

• As discussed on the onsite conducted on December 12, 2006 if the well becomes an oilwellthen a muffler will be added to the pump-jack.

• As discussed on the onsite conducted on December 12, 2006 corners 4 and 6 of the locationshall be rounded.

• 4 to6 inches of topsoilshould be stripped from the location and windrowed as shown on the cutsheet. The topsoilshall then be broadcast seeded with the recommended seed miximmediately after it has been windrowed and the seed walked into the soil with a dozer.

• The topsoil from the reserve pit should be stripped and piled separately near the reserve pit.When the reserve pit is closed, it shall be recontoured and the topsoilrespread, and the areashall be seeded in the same manner as the location topsoil.

• Once the location is plugged and abandoned, it shall be recontoured to natural contours, topsoilrespread where appropriate, and the entire location seeded with the recommended seed mix.Seeding should take place by broadcasting the seed and walking it into the soil with a dozerimmediately after the dirt work is completed.

• The best method to avoid entrainment is to pump from an off-channel location-one that does notconnect to the river during high spring flows. An infiltration gallery constructed in a BLM andService approved location is best.

• If the pump head is located in the river channel where larval fish are known to occur, thefollowing measures


6/14/2007

a. do not situate the pump in a low-flow or no-flow area as these habitats tend to concentratelarval fishes;

b. limit the amount of pumping, to the greatest extent possible, during that period of the yearwhen larval fish may be present (see above); and

c. limit the amount of pumping, to the greatest extent possible, during the pre-dawn hours aslarval drift studies indicate that this is a period of greatest daily activity.

• Screen all pump intakes with ¼" mesh material.

• Report any fish impinged on the intake screen to the Service (801.975.3330) and the UtahDivision of Wildlife Resources:
