This facility will be used to store produced water that would be either recycled for well completions or eventually disposed of at a permitted facility. The facility is currently constructed as a production pond facility and is requesting approval as a Centralized E & P Waste Management facility. It is expected that the lifespan of the site will be approximately 30 years. The site is located approximately 23 travel miles north of the DeBeque interchange (MP 61.6) along Interstate 70 (1-70) at DeBeque. The facility is located in the Northeast 1/4 of the Southeast 1/4 of Section 4, Township 6 South, Range 97 West of the 6th Principal Meridian in unincorporated Garfield County. The subject site is located on a 640 acre parcel. The property is owned by and the facility is operated by Oxy. Oxy is in the process of permitting a number of facilities located in the general area. All of these facilities will individually generate low volumes of traffic. Two facilities are for storage and will reduce the current practice of hauling materials and equipment to and from the top of the plateau. Two facilities are for the storage and management of produced water and will allow for water recycling in the field and reduce the need for trucks to haul water for final disposal. The objective of this analysis is to review the existing road network, provide traffic projections and trip assignment for the facility, and assess the need for access permitting. EXISTING ROAD NETWORK Regional trips to this facility will use the 1-70 exit at DeBeque, Colorado. Vehicles traveling to the site will drive north through the Town of DeBeque and on Mesa County 45 Road (Roan Creek Road) for approximately 3.75 miles until the road crosses the Garfield/Mesa County Line where the road transitions to Garfield County Road (CR) 204. Approximately 4.25 miles north of the county line, vehicles will turn right onto CR 213 (Conn Creek Road) and travel approximately 4 miles to the end of the county road. From this point, travel is on a series of private roads that were built and are maintained for the exclusive use of the natural gas industry. These private roads are located on property owned by Oxy. The facility is located an additional 11 miles up Cascade Creek and on the top of the Roan Plateau. There are no County or public roads within a 1 -mile radius of the facility. Oxy Pond 13 E/W 1 August, 2013 Basic Traffic Analysis Both CR 204 and 213 are preferred haul routes according to maps available on the Garfield County web -site. Both of these roads are generally used for access to ranches and agricultural operations, rural residential uses, oil and gas operations and access to public lands managed by the BLM. According to the Garfield County Road Inventory Report, CR 204 is classified as Local road and is a two lane asphalt roadway with gravel shoulders. The 2011 Garfield County HUTF Report describes the roadway as is in good condition. The road has a posted speed limit of 45 mph. During 2002, Garfield County Road & Bridge conducted a county -wide traffic study where daily traffic was counted for county roads. The study concluded that the average daily traffic (ADT) was 337 vehicles per day (vpd) on this road at that time. According to the Garfield County Road Inventory Report, CR 213 is classified as Local road and is a two lane road consisting of a section constructed of a combination of soil, gravel, and stone and a section consisting of graded and drained natural soil. The 2011 Garfield County HUTF Report describes the roadway as is in good condition. The 2002 Garfield County Road & Bridge conducted county -wide traffic study showed the CR 213 ADT to be 9 vpd for this road. There is a right -turn lane for northbound traffic on CR 204 turning right onto CR 213. The intersection is stop controlled with CR 213 as the minor leg. TRAFFIC PROJECTIONS Background traffic volumes were increased to present day values for comparison purposes. Given the lack of data regarding traffic growth for this area, a growth rate of 3% is assumed. This rate was applied to the existing counts to obtain background traffic for the year 2013. This results in an estimated ADT of 446 in 2013 for CR 204. The result for CR 213 in 2013 is an estimated ADT of 12 (Table 1). Table 1: Background Traffic Projections — Pond 13 E/W Facility Oxy Pond 13 E/W Basic Traffic Analysis 2 August, 2013 2002 Actual 2013 Estimated CR 204 337 446 CR 213 9 12 Oxy Pond 13 E/W Basic Traffic Analysis 2 August, 2013 TRIP GENERATION AND DISTRIBUTION Trip generation is generally determined using rates found in the ITE Trip Generation manual. Rates from this publication are applied to values related to the size of the proposed site to estimate the trips expected to enter and exit the site. In this case, no rates are provided for facilities similar to these. To estimate trips expected for this site, information was gathered regarding the expected traffic based on the existing operations. Vehicle activities during daily operations will consist of one (1) pickup truck per day and one (1) transport truck every two (2) days. One (1) additional pickup truck and one (1) additional transport truck will be used for maintenance purposes each quarter. Trip generation will increase by three (3) pickup trucks and one to two (1-2) transport trucks per day and one (1) additional pickup truck and one additional transport each month during periods of drilling and completion. Drilling and completion activities will occur periodically throughout the life of the project. The following Table 2 summarizes the expected average and maximum trips for the operational life of the facility. Table 2: Trip Generation — Pond 13 E/W Facility Phase Average Trips/Day Maximum Trips/Day Percent Trucks Average Total Trips/Phase Phase Duration Operation 2 4 33 % 21,900 30 years Drilling & Completions 5 7 39% N/A N/A Combined 7 11 33% N/A N/A County Road 204 Based on the County's background traffic calculations, Oxy's Pond 13 E/W facility related traffic will have an average of <1% increase on daily traffic activity during operations of the facility in 2013 on CR 204. Traffic activities will increase from the 2013 estimate an average 2.45% during drilling and completion operations on CR204. The following Table 3 summarizes the expected percentage of trips this facility will generate on CR 204.

Additionally, the majority of traffic on this road is currently associated with the natural gas industry, and the general public will not be impacted by the increase of traffic on this road. CONSTRUCTION PHASE The storage ponds are currently built and major excavation of the site will not be necessary. Only minor construction traffic will be generated by this project to bring the facility up to COGCC E&P Waste Management Facility standards. ROADWAY ANALYSIS Existing Parcel Oxy Pond 13 E/W 4 August, 2013 Basic Traffic Analysis Current land use on the subject parcel is primarily natural gas development. The majority of existing traffic on CR 213 is related to natural gas development activities, very limited agricultural activities and very low density rural residential uses. State Highway Crossings and Access The roadway access to this site does not cross any highway right-of-ways managed by the Colorado Department of Transportation. CR 204 is accessed via Mesa County 45 Road which intersects 1-70 at Exit 62 in DeBeque, Colorado. This grade -separated interchange access point is controlled by stop signs at the top of each exit ramp. Site distances are adequate in both directions at these control points. Additional traffic control is not needed at this location. The US Highway 6 / 1-70 Frontage Road terminates at Mesa County 45 Road approximately 300 feet northwest of the DeBeque interchange. This intersection is two-way stop -controlled. Traffic traveling to this site from 1-70 would have the right-of-way at this intersection. Railroad Crossings Mesa County 45 Road crosses under a main railroad line approximately 0.5 miles north of 1-70. This line is generally used for the transport of freight, coal, and passenger rail traffic. This railroad crossing is grade separated. Clearance for transport trucks under this railroad bridge is adequate. The roadway access to this site does not cross any other active railroad right-of- ways. Intersection of CR 204 & 213 As noted above, there is a deceleration/turn lane for north bound traffic on CR 204 turning right onto CR 213. A stop sign controls west bound traffic on CR 213 at the intersection of that road with CR 204. Given the amount of traffic estimated to be generated from the proposed facility, additional improvements at this intersection are not needed at this time. RECOMMENDATIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to be significant on roads generally used by the public. CR 204 will see only a minor increase in traffic. CR 213 will see a significant increase in traffic only because of a very low baseline of traffic volume. However, the total traffic volumes will remain very low and can be accommodated by the existing roadway. Additionally, the majority of traffic on this road Oxy Pond 13 E/W 5 August, 2013 Basic Traffic Analysis is associated with the natural gas industry. At worst, there would be a minor increase in traffic which would peak during drilling and completion activities. As mentioned in the Roadway Analysis, the addition of traffic generated by the proposed facility does not increase existing volumes to levels required for State or County permits.
