Hydrology Exhibit CPX Piceance Holdings, LLC Well Pad 25A 1 December 2021 Hydrology Exhibit CPX Piceance Holdings, LLC Tepee Park Ranch Well Pad 25A This Hydrology Exhibit describes the hydrology surrounding Well Pad 25A. Specifically: 1. Well Pad 25A is downgradient from an unnamed drainage to the south. 2. Well Pad 25A is cross-gradient from an unnamed drainage to the north. 3. Well Pad 25A is not within a Rule 411.a.(1) Surface Water Supply Area Buffer Zone. 4. Well Pad 25A is not within 2,640 feet of a surface water 15 stream miles upstream of a Public Water Supply Intake. The findings are discussed below. 1. Well Pad 25A is Downgradient from an Unnamed Drainage to the South Well Pad 25A is approximately 316 feet downgradient from an unnamed drainage to the south. The cut slope, shown in Figures 1 and 2, and an uphill slope lie between Well Pad 25A and the drainage. The cut slope and upgradient topography prevent flow from the well pad from reaching the drainage. The drainage is shown in Figure 3. It was confirmed to be an unnamed drainage by a Clean Water Act, Section 404, survey of wetlands and waters of the U.S., conducted by Fox Engineering Solutions, Inc. on August 18, 2021. The area is further shown on the Form 2A, Hydrology Map. Figure 1. Well Pad 25A Looking South Figure 2. Well Pad 25A Closeup of South Corner Figure 3.

Well Pad 25A is Cross-gradient from an Unnamed Drainage to the North Well Pad 25A is approximately 485 feet cross- gradient from an unnamed drainage to the north. Spruce and aspen woodland, shown in Figure 5, lies cross-gradient between Well Pad 25A the drainage. The well pad berm, cross-gradient topography, and distance prevent flow from the well pad from reaching the drainage. The drainage contains woody debris and no stream features.

Well Pad 25A is not within a Rule 411.a.(1) Surface Water Supply Area Buffer Zone Beaver Creek was removed from the city of Rifle Watershed District by Ordinance No. 7, dated June 6, 2018. Ordinance No. 7 (June 6, 2018) amended Article II, Chapter 13, of the Rifle Municipal Code to remove Beaver Creek as a Rifle Watershed District designated water source. The amendment followed the decommissioning of the city’s Beaver Creek Water Plant as a point of diversion for drinking water use by the city. A copy of Ordinance No. 7 is attached. With the removal of Beaver Creek from Rifle Watershed District designation, Well Pad 25A is not located in a Rule 411.a.(1) Surface Water Supply Area buffer zone and, more specifically, a Rule 411.a.(1).B.ii Intermediate Buffer Zone applicable to locations between 1,001 and 1,500 feet hydraulically upgradient from a Classified Water Supply Segment. Well Pad 25A and Beaver Creek are shown on the Form 2A, Hydrology Map. 4. Well Pad 25A is not within 2,640 Feet of a Surface Water 15 Stream Miles Upstream of a Public Water Supply Intake Rule 304.b.(7).E.v requires a Hydrology Map showing any surface waters within 2,640 feet of the Working Pad Surface that are 15 stream miles upstream of a Public Water Supply intake. Well Pad 25A is approximately 1,440 feet hydraulically upgradient from Beaver Creek but not within 15 stream miles upstream of a Public Water Supply intake. Figure 7 shows the confluence of Beaver Creek with the Colorado River, approximately 9 miles north. The city of Rifle public water supply intake is approximately 7 miles upstream of this confluence. One town of Parachute intake is sourced from groundwater at Revelle Spring. Revelle Spring is approximately 11 miles downstream from the confluence of Beaver Creek and the Colorado River, and 20 miles downstream from Well Pad 25A. Discussion of Revelle Spring is in the Colorado River Partnership, Source Water Protection Plan (January 2013), found at: https://www.rifleco.org/DocumentCenter/View/5650/SWPCRP_SWPP_FINAL_January_2013?bidId=v .
