BODYFELT, WYOMING PROFESSIONAL ENGINEER (CIVIL) AND LAND SURVEYOR NO. 3507 OWNER'S STATEMENT REVIEWED AND APPROVED BY: MICHA ENGINEER OFEESSSIOONA 1! / OXY USA INC. HAS REVIEWED THE DRAINAGE REPORT FOR THE POND 10 UPGRADE PROJECT AND ACCEPTS THE RESPONSIBILITY FOR IMPLEMENTING AND MAINTAINING REQUIRED DRAINAGE MITIGATION PROCEDURES DURING AND AFTER CONSTRUCTION. GARY GROVE, OXY USA INC. 1) INTRODUCTION a) Background See Sheet A-11 in Appendix A for exhibit defining Pad Area Boundary and Project Area Boundary. The existing Pond 10 facility and associated storage areas (Project Area) is being upgraded to convert two smaller storage ponds into one larger pond. The pond will store produced and flowback water from Oxy USA, Inc. (Oxy) owned or operated natural gas wells in the Cascade Creek field. The pond may also be used to store produced water from other Piceance operators to support well stimulation by hydraulic fracturing. Water will be introduced to the pond from either pipeline or water trucks. The Project Area is also being designed to mitigate drainage deficiencies and bring the Pond 10 Pad Area into compliance with Garfield County Code 4-203.D., 4-203.E., 7-204 and the COGCC regulation that states, "Surface water diversion structures, including, but not limited to berms and ditches, shall be constructed to accommodate a one hundred (100) year, twenty-four (24) hour event. The facility shall be designed and constructed with a run-on control system to prevent flow onto the facility during peak discharge and a run-off control system to contain the water volume from a twenty-five (25) year, twenty-four (24) hour storm" This report analyzes up slope flow to be routed around the Pad Area, change in water quantity resulting from the proposed construction, and mitigation measures required to control Pad Area run-on and Pad Area run-off during expected flows for design storm events. b) Project Location The Project Area is located in Tract 83-B and Tract 39, in the SE 'A of the SW % and the SW 1/4 of the SE % of Section 5, Township 7 South, Range 97 West, 6th Principal Meridian, Garfield County, Colorado. Driving directions to the Project Area are described as follows: From De Beque, Colorado, head northwesterly on 45 Rd for 3.2 miles. Continue northerly onto County Road 204 into Garfield County for 4.0 miles. Turn right onto County Road 213/Conn Creek Road and continue easterly then northeasterly 3.9 miles. The Project Area is located about 300' east of County Road 213 at this location. See Sheet A-1 in Appendix A for surrounding area vicinity map. Center of Pond 10 coordinates are approximated in NAD 83 Datum as: Latitude: 39.468404° N Longitude: 108.244602' W C) Property Description Project Area is bounded on the west by toe of existing 2:1 (H:V) pad slope, bounded on the north by an existing and proposed swale 52, bounded on the east by an existing and proposed swale S1 and bounded on the south by existing and proposed swales SR1 and S1. Pad Area is bounded on the west by top of existing pad with a 2:1 slope, bounded on the north by proposed swale S3, bounded on the east by top of an existing and proposed berm expansion and bounded on the south by top of a proposed pad expansion in existing storage area 3 with a 2:1 slope. Existing ground conditions in undisturbed regions of the Project Area are lightly vegetated with grasses, weeds and sage. Travel surfaces on the pad and storage areas 1, 2 and 3 are mostly bare dirt with a small amount of gravel intermixed. Disturbed steep side slopes within the Project Area are mostly bare soil with sparse grasses and weeds. The Project Area is zoned as Resource Lands as indicated by the Garfield County Zone District Map. d) Previous Investigations To our understanding, no previous investigations of the Project Area drainage have been conducted or approved regarding this location. 2) DRAINAGE SYSTEM DESCRIPTION a) Existing Drainage Conditions Existing conditions consist of a relatively level pad area with projecting 2:1 slopes extending from the north and east pad edges up to daylight with historic contours and 2:1 slopes extending south and west from the pad edge down to meet with the access road and parking lot chain up area. Project Area soil conditions are mainly open ground with the entire Project Area having hydrologic soil group B designation which has "moderately low runoff potential when thoroughly wet" as defined by the Natural Resources Conservation Service (MRCS). See the hydrologic soil group maps produced by the NRCS in Appendix B. Pad Area has an effective runoff area of approximately 3.33 acres excluding the existing Pond 10 area. Storm water that falls on the Pad Area is either trapped in puddles on the pad area or drains off the west and south edge of the pad to Conn Creek by way of sheet flow, ditches, culverts, concrete vaults and existing swales. Project Area north of the Pad Area has limited runoff control or treatment. Water is prevented from flowing onto this area by protection from existing swale 52, but water falling on this area flows southwesterly across existing storage areas 1 and 2 and into the borrow ditch east of Oxy's private access road. The Project Area east of the Pad Area drains to an existing set of swales in the proposed swale S1 vicinity. Runoff is treated in a sediment trap prior to being discharged through a culvert in the vicinity of proposed cattle guard C3. In the Project Area south of the Pad Area, storm water currently runs down the steep slope from the pad fill and crosses the access road before being collected in the existing swale near proposed swale SR1 and routing to Conn Creek. The Project Area west of Pad Area drains down the steep 2:1 fill slope from the pad and sheet flows across the parking lot chain up area before being collected in the borrow ditch east of Oxy's private access road. b) Offsite Drainage The area that historically drained across the Pad Area is a steep sloping hillside that has an area of approximately 83.46 acres and is designated in this report as basin W1. Potential for development on this terrain is minimal to non-existent; accordingly, future development for areas upstream of the Pad Area was not taken into consideration for this report. c) Proposed Drainage System Description To meet COGCC regulations regarding Pad Area run-on and run-off, new proposed and upgraded existing swales were designed to direct flow around the Pad Area to prevent run-on. To capture, convey and store stormwater on the Pad Area to prevent run-off, the proposed pad was designed to gently slope from northwest to southeast as well as away from Pond 10. Storm water landing on the Pad Area was designed to be collected in swales SP1 and 5P2 around the exterior of the pad and transported at a -1% slope to the proposed retention pond in the southeast corner of the Pad Area. Swales were sized to transport runoff from a 100 year, 24 hour storm event and the retention pond was sized to retain water from a 25 year, 24 hour storm event. See Appendix A for layout of delineated watersheds and proposed drainage plan. W1 is the 83.46 acre basin east of the Pad Area. Storm runoff from this basin will be collected in swale 51 and discharged into a sediment trap at design point (1). From the sediment trap, flow will pass under an access road through a cattle guard with concrete vault at C3 and discharge to open sage lands. W2 is the 3.74 acre basin north and northeast of storage area 1. Storm runoff from this basin will be collected in swale 52 and discharged to the borrow ditch on the east side of Oxy's private access road at design point (2). Flow will travel south and east through existing culverts to cross an approach and Oxy's private access road before finally discharging into Conn Creek. W3 is the 1.07 acre basin just north of the Pad Area. Storm runoff from this basin will be collected in swale S3, travel across pad access under a cattle guard at C1 and discharge to a sediment trap at design point (3). Sediment trap overflow will sheet flow across the parking lot and chain up area to the borrow ditch on the east side of Oxy's private access road and cross Oxy's private access road through a culvert discharging to Conn Creek. P1 is the 3.21 acre basin known as the Pad Area. Storm runoff from the hill and pad north and east of Pond 10 will be collected in swale SP1 and transported to the retention pond at design point (10). Storm runoff from the pad south and west of Pond 10 will be collected in swale SP2 and transported under a cattle guard at C2 to the retention pond at design point (11). The retention pond and portion of land that flows directly into the retention pond is included in P1 while Pond 10 is excluded from basin P1 for the purpose of this report. Snow falling on the Pad Area will be stockpiled only as needed to allow normal and necessary operations. Stockpiled snow will be directed toward 13MPs when practical to allow treatment. Plowed snow will likely be placed near the outer boundary of the pad so pad swales will collect the snow melt and route it to the retention pond. P51 is the 2.19 acre basin containing storage areas 1 and 2. All storm runoff from P51 is collected by three swales 57, 58 and S9 and directed into a sediment trap at design point (5). More particularly, storm runoff from about the northwest half of storage area 1 is collected by swale 57 and discharged into the sediment trap at design point (7). Storm runoff from about the southeast half of storage area 1 is collected by swale S8 and discharged into the sediment trap at design point (8). Storm runoff from storage area 2 is collected by swale S9 and discharged into the sediment trap at design point (9). Sediment trap overflow will sheet flow to the borrow ditch on the east side of Oxy's private access road and pass through existing culverts to cross an approach and Oxy's private access road discharging into Conn Creek. The Pad Area retention pond at design point (4) was designed to retain all storm runoff from P1 during a 25 year 24 hour event. The pond has a volume at pool elevation 5843 of 0.59 acre-feet. The retention pond was located entirely in cut and has a depth of 8.0' at the designated pool elevation. Sediment trap 1 at design point (5) was intended to trap sediment and improve discharged water quality from P51. The trap has a volume of 0.038 acre-feet at pool elevation 5843.5'. This trap is entirely in cut and has a depth of 4.0' at the designated pool elevation. Sediment trap 2 at design point (3) was designed to trap sediment and improve discharged water quality from W3. The trap has a volume of 0.043 acre-feet at pool elevation 5832'. This trap is partially in cut and partially in fill and has a depth of 3.0'. Sediment trap 3 at design point (1) was planned to trap sediment and improve discharged water quality from W1. The trap has a volume of 0.056 acre-feet at pool elevation 5850'. This trap is partially in cut and partially in fill and has a depth of 5.0'. See proposed drainage ditches and concrete cattle guard vaults on sheets 3 Appendix A. d) Drainage Facility Maintenance Owner will be required to perform regular maintenance of swales, sediment traps, cattle guards, concrete vaults, rip rap and retention pond. Swales, cattle guards and concrete vaults should be graded or cleaned out every one to three years or as needed after all significant storm events. Sediment traps and retention pond should be dredged and re -graded as needed to maintain depth, dimensions and side slopes. Proper Best Management Practices (BMPs) shall be utilized by contractor during construction to prevent Project Area run-off of soil laden waters. Contractor shall utilize BMPs as needed to maintain water quality during construction using methods described in the Urban Storm Drainage Criteria Manual Volume 3. Silt fence, sediment control logs, straw bale barriers, rock socks or other mitigation measures shall be employed. Additional measures shall be added if determined necessary in the field by a qualified person. A majority of BMP elements are already in place and are maintained on a regular basis. Additional BMPs will expand and increase the effectiveness of the existing BMP system. An estimated cost for BMP installation and maintenance during the construction phase is $10,000. An estimated cost to maintain and keep the BMPs in effective working order is $4,000 annually. 3) DRAINAGE ANALYSIS AND DESIGN CRITERIA a) Regulations Production of this drainage report follows normal and customary engineering practices for this type and nature of work. The Stormwater Management Manual for Grand Junction and Mesa County and Garfield County Land Use and Development Codes 4- 203.D., 4-203.E., and 7-204 were used as a design and formatting guideline. b) Development Criteria No known drainage constraints have been previously placed on the Project Area due to drainage studies, floodplain studies or a master drainage plan. Location of retention pond in the southeast corner of the Pad Area was restrained to some degree by the land boundary to the south. A parking lot and chain up area is adjacent westerly of the Project Area limiting the dimensions of sediment trap 2. There are no developments adjacent to the north or east edges of the Project Area limiting drainage system components. Drainage systems were designed to eliminate flow onto the Pad Area during a 100 year, 24 hour event and retain the precipitation on the Pad Area during a 25 year, 24 hour event. c) Hydrologic Criteria Hydrologic calculations performed during design of the Project Area drainage systems were according to normal and customary engineering practices. The rational method was utilized in development of hydrologic design storms. See Appendix B for all hydrologic calculations. d) Hydraulic Criteria Hydraulic calculations performed during design of the Project Area drainage systems were according to normal and customary engineering practices. Hydraulic flow through each swale was estimated using Manning's Equation. See Appendix C for all hydraulic calculations. 4) CONSTRUCTION a) Schedule See Table 2 for the anticipated construction sequence, schedule and duration for each item of the Project Area. Approximate Pond 10 Construction Schedule Construction Item Date Duration Pond 10 Excavation Begin 5/1/14 14 days Pond 10 Excavation Completion 5/15/14 Pad Grading Begin 5/16/14 14 days Pad Grading Completion 5/31/14 Earthwork and BMP Installation Off Pad Begin 6/1/14 30 days Earthwork and BMP Installation Off Pad Completion 6/30/14 Complete Clean Up and Seed Required Areas 7/15/14 2 Growing Seasons Revegetation to 70% Cover of Surrounding Native 7/15/16 a b) Excess Soil The excess soil will be spread out to blend with existing contours and slopes will be kept to a minimum to promote vegetative regrowth and limit erosion. 5) POST CONSTRUCTION a) Stormwater Quality Control Measures After construction, stormwater falling on the Pad Area during a 25 year, 24 hour event will be retained in the retention pond. In extreme storm events, sediment will be trapped in the retention pond before water escapes over the emergency overflow. Offsite stormwater from a 100 year, 24 hour event will be routed around the Pad Area in proposed and upgraded swales to eliminate flow onto the Pad Area. Stormwater flowing around the Pad Area will be directed through sediment traps to prevent sediment laden waters from continuing downstream. Stormwater falling in Pond 10 will be retained within the Pond 10 containment. Safety containment systems for Pond 10 include a geosynthetic clay liner, a double 60 -mil HDPE liner system with sandwiched geonet and two site wells to check for seepage through the primary liner. The pump pad adjacent to the south edge of Pond 10 will consist of a concrete pad with an exterior lip to ensure containment in case of spills. Proposed construction will result in very little change to impervious regions on the Project Area. b) Calculations See Appendix B for hydrologic calculations regarding stormwater management. c) Reclamation Areas disturbed by construction activity not intended for long-term functioning of the Project Area will be reclaimed. Proposed reclamation will be similar to or better than existing Project Area conditions. Disturbed cut and fill slopes from the pad will be hydromulched and seeded with a seed mix consisting of a diversity of native or desirable nonnative species capable of supporting the post -disturbance land use. Vegetation will be established and growing within 2 growing seasons based on 70% coverage as compared to surrounding native vegetation coverage. 6) CONCLUSIONS a) Compliance This report has been prepared in accordance with normal and customary engineering practices for this type and nature of work. The Stormwater Management Manual was used as a baseline for design calculations and applicable items listed in Garfield County Codes 4-203.0., 4-203.E. and 7-204 were addressed. b) Design Effectiveness With proper application of the proposed drainage mitigation design presented in this report, runoff effects onto areas downstream of the Project Area will be alleviated. c) Areas in Flood Hazard Zones There are no flood hazard zones designated by FEMA for the Project Area. The Project Area is classified as Zone 0. 7) REFERENCES 1.) Stormwater Management Manual Grand Junction Municipal Code Title 26, December 4, 2013 2.)

ERO surveyed the project area on May 24, 2014. The pond and storage areas are located approximately 10 miles north of DeBeque, Colorado. Location and Existing Conditions For the purposes of the proposed project, the survey area was defined as a uniform 0.5 mile surrounding the existing project envelope (Figure 1). The legal description of the approximate center of the project area is Sections 5 and 8, T7S, R97W of the 6th PM; UTM NAD 83 Zone 12N, 737050m Easting, 4372373m Northing; Latitude, Longitude: 39.468305°N, -108.244193°W; USGS Red Pinnacle, CO Quadrangle. Oxy is the surface owner. The ponds are in the process of being cleared and excavated. Heavy machinery was on-site and operating at the time of the site review (see Photo 1 and Photo 2). Site Summary Pond 10 and associated storage areas are in a valley bottom at an approximate elevation of 5,800 feet above sea level (Figure 1). The existing pond location and parking/access/storage areas consist of graveled and maintained surfaces with minimal to no vegetation. These developed areas are immediately surrounded by sagebrush - steppe habitat. Cliff and cottonwood riparian habitat occur within 0.25 mile of the project area. The sagebrush -steppe habitat is dominated by sagebrush (Artemesia tridentate sp.), primarily along the eastern project area boundary. Dominant vegetation in the Pond 10 project area is predominantly the same as reported in the previous site review and documentation (March 20, 2014), and is listed m Table 1. Some new weed occurrences were documented, as expected with disturbed site conditions (see Noxious Weed section of report). Consultants in Natural Resources and the Environment Photo 1. Looking northwest from southern edge of Pond 10 (5.24.14). • Photo 2. Looking south from Pond 10 Storage Area (5.24.14). Table 1. Vegetation observed near Pond 10.

The reviewer remained on site for nearly 2 hours and scanned habitat throughout the site review. Potential habitat includes cottonwood trees along Conn Creek south and west of the project area, and cliff habitat east and west of the project area. A few scattered juniper trees are present east of the project site but are not large enough to support raptor nests. No raptor nests or raptors were observed. Two bird species—king bird and magpie—were observed north of the site. These species appeared to be foraging in riparian areas and grasslands north of the project site, and were not disturbed by project activities. Both species are adapted to human activity levels and are tolerant of disturbance. Noxious weeds The Colorado Noxious Weed Act designates undesirable plants that are considered threats to Colorado's natural resources. The Colorado Noxious Weed Act contains three lists of noxious weeds: List A, List B and List C. List A and 13 weeds are targeted for eradication. List C species are not considered major threats at this time and are not currently subject to eradication. Garfield County has designated 20 species as noxious weeds (Table 2). Table 2.

Musk thistle was observed in the project area. Several other weedy species were observed (cheatgrass, bindweed, and perennial peppergrass) but these are not on the Garfield County noxious weed list. Oxy monitors and treats noxious weeds seasonally typically with bareground treatments in the early spring followed by hand -spray applications upon detection of noxious weeds. Oxy tracks noxious weed treatment in compliance with Oxy's Noxious Weed Management Plan. Please feel free to contact me at (970) 872-3020 or apowers@eroresources.com if you have any questions.
