The pipeline will support Ursa Resources ongoing natural gas production in the area. The project is located across the parcel no.: 2179-114-00-114. Valley Farms L Pad Exhibit: One 8" gas pipeline and two 12" water line will leave the Valley Farms L Pad from the South side (Parcel No. 2179-114-00-114). The lines will run east within the 50' ROW for a total pipeline disturbance distance of 760 ft. It is anticipated that the excavation will not exceed 48" in width with a depth of 60". Total excavated material is expected to be approximately 563 cubic yards, total disturbed surface area 38,000 ft2 (0.87 Acres). All materials are to remain within the established ROW. The pipeline will be final graded and seeded according to Garfield County guidelines/stipulations. The existing topography will be maintained after the pipelines are installed so no change in the drainage pattern is expected. Vicinity Map: See attached maps in section 3 of this document Site Plan / Pipeline Route: See attached maps in section 3 of this document Letter of Authority: See the attached copy of the existing land owner agreement (Section 3 of this document). Erosion Control Plan and Details Erosion prevention best management practices (BMPs) will be implemented and maintain in accordance with Ursa's approved Storm Water Plan dated 5/21/2013 (see section 5 for plan). The BMP's described in the plan will be utilized and inspected as necessary during the course of construction and re -vegetation of the ROW. The expected locations of the BMP's are shown on the site Plan as indicated and the site plan supporting project maps are included in the most recent version of the company's SWMP. KAHUNA VENTURES LLC NATURAL GAS PROCESSING, TREATING Si PROJECT CONSULTING Major Grading Permit This permit application is considered as a Major Grading Permit category based on the total square feet disturbed by the project (Approximately 38,000 square feet; 0.87 Acres). 1.

This is based on a 50 foot wide Right -of -Way (ROW) along the 760 feet pipeline length. The actual volume of soil moved is based on a 5 foot deep pipeline trench that is 5 feet 8 inches wide over the same length and totals approximately 798 cubic yards. Top soil will be scraped off first and stored in a separate spoil pile along the ROW for replacement once the final grade is restored after construction. In order to minimize erosion during construction, existing vegetation and trees will be preserved wherever possible. Erosion control will be in accordance with Ursa's State approved Storm Water Pollution Plan and the appropriate BMP's will be utilized along the ROW as needed. Weed -free straw will be utilized where straw bales or straw wattles are indicated for erosion prevention/control. Dust suppression will be handled by a water truck along the ROW on an as needed basis. Weed Management Plan Ursa/Consultant has obtained the latest County Listed Noxious Weeds from the Garfield County Vegetation Management Department. A field inspection of the project area was conducted by a HRL Compliance Solutions biologist on July 14`h, 2014. The HRL biologists did has provided a log of the survey- noting no traceable noxious weed species within the planned ROW. Vegetation types will be determined through field identification of plants, aerial photography, and on - the -ground assessment of plant abundance visible during the survey. Identification of plant species will be aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998, Weber and Wittmann 2001). Photographs will be taken of the general project location, vegetation, terrain, and other specific biological findings. Locations of weeds and other features to be included in this survey report will be recorded with the aid of a handheld global positioning system (GPS) receiver using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 13. Since the construction is proposed for the summer, Ursa will seed the ROW upon completion of the work to take advantage of the growing season and on a monthly basis until the native/reseeding has taken hold of the disturbed ground. The ROW will be inspected every two weeks after completion of construction to insure reseeding is effective and the weed control is working. The weed treatment program and reseeding efforts will be enhanced in response to the findings of these inspections. 5. KAHUNA VENTURES LLC NATURAL GAS PROCESSING, TREATING & PROJECT CONSULTING Description of Permanent Stabilization Practices All disturbed areas will be re-contoured so that the disturbed area blends into the surrounding terrain. Reseeding of the ROW will occur in the late-April/early-May timeframe depending on the weather conditions at the time. Pipeline projects on agricultural land (crop or rangeland), the permanent stabilization will be accomplished by returning the disturbed land to its pre -construction agricultural use. Such areas will be will be graded, but not re -seeded unless required by an agreement with the landowner. In areas that were not previously used for agricultural activities, final stabilization will be accomplished when all soil -disturbing activities have been completed and a uniform perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been established. In areas with no natural vegetation (sandy areas, rocky areas, etc), no stabilization is required. The project will use two different types of seed mixtures in obtaining final stabilization. One grass mixture is specific to the most commonly grown grasses on dry lands. The second type of seed mixture is similar to common naturally occurring grasses on irrigated lands in the area. The seed mixtures are shown below: Dry Land Mix Pure % Germ% Origin Crested Wheatgrass, Hycrest 19.58% 94% CAN Smooth Brome, Lincoln 18.17% 95% KS Perennial Ryegrass VNS 14.99% 90% OR Slender Wheatgrass, Revenue 14.62% 96% CAN Orchardgrass, Renegade 14.37% 90% OR Tetraploid Intermediate Wheatgrass, 9.64% 94% WA Oahe Dahurian Wildrye, VNS 4.96% 98% CAN Irrigated Land Mix Orchardgrass, Potomac 32.0% 90% OR Tall Rescue, Rustler 22.55% 92% OR Tetraploid Perennial Ryegrass,Verano 19.51% 90% UK Smooth Brome, Lincoln 13.17% 95% KS The use of these two mixtures should result in quick re -stabilization. Plant hydration, if inadequate through natural means, will be provided by tractor/truck mounted sprayers on an as needed basis until adequate re -vegetation has been established. Timing of Stabilization Stabilization must be completed no later than fourteen (14) days from the last construction activity in that work area. In areas experiencing droughts where the initiation of stabilization measures by the 14th day after construction activity has temporarily or permanently ceased is not possible due to drought conditions, stabilization measures shall be initiated as soon as practicable. Where the initiation of stabilization measures by the 14th day after construction activity temporarily or permanently ceases, is not possible due to snow cover or frozen ground conditions, stabilization measures shall be initiated as soon as practicable. If an unforeseen event causes the project to be 2 KAHUNA VENTURES LLC NATURAL GAS PROCESSING, TREATING & PROJECT CONSULTING temporarily suspended for a period of twenty-one (21) days or more, stabilization activities (planting and/or mulching) will be undertaken as soon as possible. Creek or stream banks will be stabilized immediately upon completion of the construction. (Nationwide Permit #12 condition).

Bracing and reinforcing are to be done prior to cutting. These gaps shall be kept closed by Contractor, except when actually being used. b. Contractor will be liable for all damage claims arising from the straying of livestock due to Contractor's failure to close gates or gaps and to properly maintain fences. After the work is completed, all fence gaps are to be removed and fences permanently repaired or permanent gates installed. Materials used for repair of fences shall match the original fence as nearly as practicable with regard to gauge, mesh style and appearance. These repairs shall be satisfactory to the landowner, his tenant or lessee, and Company. 2.3 Grading a. Contractor shall remove all stumps in the way of the trench. Contractor shall perform such grading that is needed to minimize the necessity of overbends or sag -bends, and/or to prevent excess or irreparable damage to the property. Excess excavated material shall be placed in piles within the right-of-way in such a manner that it may be replaced in its original location. Such material shall not 6 be scattered along the right-of-way in such a manner as to block natural drainage. Material removed from creek and river banks shall not be placed in the stream bed or where stream flow or drainage will be obstructed. After the pipe has been laid, material excavated from hillsides, creek or river banks, and such other places shall be replaced in its original position and protected from slides and erosion by rip -rap, sack breakers, diversion terraces, or such other means as may be required. 2.4 Preservation of Survey Markers a. Before clearing and grading the right-of-way, Contractor shall move survey stakes back to the edge of the right-of-way and preserve them during all phases of the work for use in reporting progress and locations along the line. Cost of replacing survey stakes which have been destroyed due to carelessness of Contractor, will be paid by Contractor. After clearing and grading of the right-of-way, Contractor shall reset survey stakes in their original location. As ditching progresses, Contractor will move survey stakes to the edge of right-of-way and preserve them until the ditch is backfilled and cleanup is completed. STRINGING 3.1 Material Delivery a. Pipe and other materials delivered to the Contractor, shall be promptly received, unloaded from delivery vehicles at Contractor's warehouse, pipe yard, or may be strung directly onto the right-of- way. The unloading and handling of all materials shall be accomplished by the Contractor in a careful workmanlike manner and by the use of equipment and labor satisfactory to the Company's Representative. Upon receipt of pipe and other materials the Contractor is responsible for any damage or loss thereafter. Coated pipe shall, at all times, be handled with equipment such as wide canvas slings or wide padded skids designed to prevent damage to the coating.

Any weld containing a crack shall be completely removed from the line. The Company may authorize repairs of other defects in the root and filler beads, but any weld that shows evidence of repair work having been done without authorization by the Company may be rejected. Repairs may be made to pin holes and undercuts in the final bead without authorization, but must meet approval of the Company's Representative. In any event, only repairs authorized by API 1104, latest edition, will be permitted. o. Before repairs are made, injurious defects shall be entirely removed by grinding to clean metal. All slag and scale shall be removed by wire brushing. Preheating of such an area may be required by the Company. p. All arc burns must be repaired by removing the notch, either by grinding, or cutting out a cylinder of the pipe containing the entire notch. Grinding the notch shall be permitted provided grinding does not reduce the nominal wall thickness in excess of 121/4 percent to remove all the physical defects of the arc burn. In the event grinding is unsuccessful, the damaged area of the pipe containing the arc burn, including the ground area, shall be removed by cutting out a cylinder of the pipe containing the damaged metal. q. Tack welding of grounding clamps and other devices to pipe shall not be permitted. r. The maximum distance between the pipe gang (stringer bead and hot pass welders) and the firing 11 line (finishing welders) shall be determined by Company Representative.

The results of these runs shall determine if the line is free of debris and that no pipe buckles or excessive out of roundness is in the section. If excessive air pressure is needed to move the pig, an obstruction in the pipeline is apparent. Additional pig runs may be required to locate such an obstruction. All obstructions must be removed by Contractor, at Contractor's expense, or otherwise accounted for to Company's satisfaction. 25 12.6 Filling Procedures a. Permits required by government authority will be secured by Contractor and copy provided to Company's Representative prior to the filling operation. After all pretest operations are performed, Contractor shall supply all the necessary fill equipment as previously specified herein. The general fill operation shall be performed as described below. 1. The water filter unit shall be installed on the fill pump discharge line. Contractor shall install a pressure dial gauge on the fill pump discharge for observing the heads that are encountered while pressurizing. This gauge shall not be used for accumulation of data, but the highest pressure obtained during the filling operation shall be noted on the records to be kept pursuant as specified in Section 12, "Testing", noted in paragraph 12.9. 2. The Contractor shall supply fill pumps that are capable of filling the line at a rate not to exceed six (6) hours and shall proceed to fill the pipeline section. 3. All vents and other connections shall be opened as required to eliminate air from the lines during filling operations. 4. Contractor shall introduce a squeegee (batching pig) consisting of a minimum of four (4) rubber or polyurethane discs and/or cups or other acceptable pig, into the line to eliminate air from the pipeline. Should the Contractor elect to fill the section from the middle, one (1) squeegee as described above, shall be place in each direction of fill. 5. Contractor shall supply and install all instrument lines required for test. All lines shall be either high pressure tubing or hose. Contractor shall install a thermometer on the surface of the pipe near both ends of the test section. 6.

Whenever possible, Contractor shall allow the water to remain in the line overnight to allow the water temperature to stabilize with the surrounding ground temperature prior to pressuring. b. Upon completion of the filling operations, the Contractor shall pressure the pipeline test section as described below. The Company may elect initially to test the pipeline section at a different pressure than specified in the Contract. c. Pressuring Operations 1. Pressure and temperature recording gauges, and the dead weight tester shall be at one end of the test section where the pressure pump is located and a dial gauge at the other end. The final test pressure of both ends will be calculated according to the elevations at each end. Contractor may also be required to install gauges at other locations on the pipeline where the segment could be isolated from the test pressure by check or block valves. 26 2. Contractor shall stop the pump at a pressure 50 psig below the test pressure so that a thirty (30) minute duration lead test can be made. At the end of this time period, pressure readings at both ends shall be compared and checked with elevation differences, and adjustment of final test pressures made if necessary. Dead weight readings shall be taken at five (5) minute intervals. This procedure will determine whether or not a leak exists and will prevent over -pressurization. Since there will be some difference between the temperature of the water used to fill the test section and the temperature of the pipe and surrounding backfill there will be a natural change in pressure until these temperatures equalize as specified in Section 12, "Testing" The rate of change will diminish with time and can be observed on the recording gauge, or by charting dead weight readings at regular time intervals. Should there be no changes in pressure as indicated by dead weight readings during this period of time, then Contractor shall proceed with the test as specified in Section 12, "Testing", noted in subsection 12.8.e.1 herein. d. Procedures for Locating and Repairing Leaks or Failures During Hydrostatic Testing 1. Should the procedure as specified in Section 12, "Testing", noted in subsection 12.8.c.2 above indicate that a leak exists then the Contractor should check all possible sources of leaks by checking all valves, instrument lines, exposed piping and test equipment. Should no leaks be found then an underground leak is indicated. 2. At this point, Contractor shall furnish labor and equipment to locate and repair the leak or failure. After repairs are made, Contractor shall refill and restore the pressure to that point at which it failed or a leak was detected. 3. Should a leak occur due to faulty workmanship by Contractor or due to failure or negligence of Contractor, then Contractor shall bear all costs incurred for locating and repairing such leak. 4. Should a leak occur due to faulty or defective material furnished by Company then Company shall reimburse Contractor for all costs incurred for locating and repairing of such leak and for the cost of bringing the test procedure to the point attained at the time the leak was detected. Any leaks found shall be repaired to original Company specifications. 5. Upon deciding that a leak exists in any test section, then Contractor shall furnish Company the following information prior to proceeding to locate and repair the leak: a. A list of equipment to be used in locating the leak for the approval of Company. b. A list of personnel, including names and classifications to be utilized in locating the leak for the approval of Company. c. Contractor shall not proceed to locate the leak until receiving written approval of Company for the use of such equipment and personnel. 27 6. Proper records shall be kept with regard to all work performed in locating and repairing all leaks or failures. e. Procedure After Repair of Leak or Failure. After the repair of a leak or failure, Contractor shall reinstate the necessary filling and pressure procedure as outlined previously and then proceed as follows: 1. Contractor shall then pressurize the pipeline section to the specified test pressure taking dead weight readings at 5 psig increments for the last increase of 50 psig. Contractor shall terminate the pressure operations when the specified test pressure is reached. 2. Contractor shall hold the test pressure for the length of time required in the Contract taking dead weight readings at thirty (30) minute intervals and providing a continuous test recording for the duration of the test. If during the test a pressure loss occurs, then the pressure shall be allowed to stabilize. At such time as the test pressure stabilizes for a period of one (1) hour, then the Contractor shall pressurize the test section back to the test pressure as specified in Section 12, "Testing" The test period shall again commence after any re -pressure. No re - pressure shall occur during the test period. Prior to ending the test, all data shall be assembled and analyzed by the Company Representative to determine if the test is acceptable. 3. Change in Pressure. In the event a continuous decrease in pressure is observed, Contractor shall re -pressure the section to the specified test pressure after an elapsed time of two (2) hours. If a continuation of pressure loss is observed within the next two (2) hour period, a leak is evident. Therefore, the Contractor shall discontinue the testing until the leak has been located and subsequent repair(s) made. If the pressure stabilizes within these four (4) hours, Contractor shall re -pressure to specified test pressure and proceed with the test program. Contractor shall not permit the pressure during the test to increase in excess of 50 psig above the test pressure. 12.8 Records Contractor shall keep an accurate report of all data obtained.
