Minor Temporary Housing Facility Laramie Energy, LLC (Laramie) is pursuing a Minor Temporary Housing Facility (MTHF) in Garfield County for the use of temporary employee housing. The temporary employee housing will be located at the Cascade Creek (CC) 0610-21-41 Pad. The proposed employee housing will be located on an approved oil and gas location (well pad), approximately 13 mapped miles north of DeBeque, Colorado. The site use will be defined as a Minor Temporary Housing Facility use. The MTHF main function will be to accommodate personnel and provide temporary housing during drilling operations at the subject well pad. The MTHF will adhere to Garfield County rules and standards set forth in the Garfield County Land Use and Development Code (LUDC). The following application addresses the submission requirements for Article 4 Section 301 Minor Temporary Housing Facility of the LUDC. Section 4-301.A.1. General application materials pursuant to 4-203.B. Article 4 Section 203.B.5. - Project Description The following section addresses the requirements for the Project Description under Article 4 Section 203.B.5 of the Garfield County Land Use and Development Code (LUDC). The purpose of the proposed MTHF will be to provide temporary employee housing for 24 or fewer personnel during drilling activities. The temporary employee housing will be located on site for a period of less than one year. Laramie anticipates drilling operations to occur for 137 days with drilling commencing on June 22nd, 2022, or possibly later. Laramie is currently drilling on the CC 0697-03-07 well pad located just one mile north of the CC 0610-21-41. Once drilling activities are completed on the CC 0697-03-07, the drill rig and temporary employee housing will be mobilized to the CC 0610-21-41 pad. Both well pads are located on parcels owned by Couey Family LLLP (Couey) and will not require mobilization on public roads. Drilling activities and temporary employee housing will not occur concurrently at the CC 0697-03-07 and CC 0610-21-41. Since drilling will commence at the CC 0610-21-41 following the completion of drilling at the CC 0697-03-07, Laramie does not have an exact drilling start date for the CC 0610-21-41. Laramie anticipates drilling will start at the CC 0610-21-41 pad between July 20, 2022, and August 1st, 2022. Laramie will notify Garfield County within 48 hours of mobilization to the CC 0610-21-41.

A site visit was conducted on July 1, 2022 at the well pad to evaluate the existing vault OWTS serving the temporary housing facility providing living quarters for up to 24 maximum occupants with an anticipated occupancy of 21 people. The most occupants anticipated in any one mobile home trailer unit is 5 people. Two of the five mobile homes will be occupied by 5 people. Temporary housing, located within the confines of the well pad, provides living quarters in five (5) mobile home trailers with full kitchen, laundry, and bathroom facilities. Potable water is supplied from three (3) 3,360 gallon water tanks plumbed with water meters that are resupplied with 3,500 gallons of water delivered twice a week. Wastewater generated from each mobile home (75 gpd/person) gravity flows to a Pro380 Liberty vertical discharge grinder pump housed in a 41 gallon sump pump basin with factory pre-set pump and alarm floats for proper operating levels. The grinder pumps operate on a demand dosing cycle discharging wastewater to one of the four (4) 1,800 gallon wastewater tanks each equipped with a high level alarm activating when tanks reach 70% capacity. Wastewater is hauled from the well pad at least twice per week using a 5,000 gallon capacity tanker pump truck. WestWater Engineering has determined the OWTS vaults and pumps serving the temporary housing for the Laramie Energy well drill sites are adequately designed and sized in accordance with Garfield County OWTS Regulations. These findings are based on the site visit and Laramie Energy’s narrative prepared for Garfield County for CC 0697-03-07 Pad Minor Temporary Housing Facility Application Narrative dated March 2022. Garfield County OWTS Regulations assign a 50 gpd/person daily wastewater flow for semi- permanent work or construction camps with flush toilets. Laramie Energy assigns a 75 gpd/person daily wastewater flow for temporary housing occupants thus a 50% safety peaking Laramie Cascade Creek Operations Area Access Roads Garfield County Roadway Standards Section 7-107. ACCESS AND ROADWAYS Laramie Energy, LLC 760 Horizon Drive, Suite 101 Grand Junction, CO 81506 The following narrative and documents address the requirements for the Access and Roadways Standards under Article 7, Division 1 of the Garfield County Land Use and Development Code (LUDC). Laramie is requesting a waiver to Standard 7-107. Access and Roadways. Like many of the historical roadways in Garfield County, Laramie’s private access and roadways were established prior to the Garfield County’s roadway standards. Laramie’s roadways are maintained to provide safe access to sites and are inspected for stormwater compliance. Roadways were designed for oil and gas transportation vehicles and equipment. These roads are not intended for or allow public access. Laramie enforces reduced vehicular speeds and specific safety driving measures. All roads located on the subject parcel are maintained by Laramie to achieve optimal safety, including speed restrictions, regular road maintenance, dust controls, and snow maintenance. The CC 0610-21-41 Pad is located within Laramie’s Cascade Creek oil and gas operations area. The site is located approximately 11.5 miles from the nearest public road, County Road 213. To access the site, vehicles will travel on privately owned and maintained Cascade Creek field access roads. The roads were constructed by the previous operator, OXY USA WTP LP (OXY). OXY pursued land use change permits while as owner and operated of the Cascade Creek field and subject parcel. Garfield County reviewed and accepted a waiver for the Cascade Creek operating field roads in 2015. OXY’s roadway assessment documents, approved by Garfield County, are provided in Standards tab. The Laramie took ownership of the Cascade Creek operations area in 2016. Laramie has continued maintain and improve the roadways located within the Cascade Creek field. D.R. Griffin and Associated (DRG) worked with OXY to design and construct the Cascade Creek Roadway system. DRG’s engineer reviewed OXY’s approved roadway assessment documents and agree with the reports. Garfield County’ Policy 01-14, “Waivers for Roads and Demonstration of Compliance”, states roads must be deemed “safe and adequate” by a Professional Engineer (PE). DRG submitted a PE stamped letter addressing Laramie’s access roads. A PE from Rock Solid Solutions deemed the network of roadways “safe and adequate”. •DRG Letter •Rock Solid Solution Letter •OXY Roadway Assessment Packet GARFIELD COUNTY ROADWAY STANDARDS ASSESSMENT PREPARED FOR OXY USA WTP LP Grand Junction, Colorado PREPARED BY Olsson Associates 760 Horizon Drive, Suite 102 Grand Junction, CO 81506 970-263-7800 January 2015 Olsson Associates Project No. 013-0655 Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 i Table of Contents 1.0 CASCADE CREEK VALLEY ROAD................................................................................... 1 1.1 Scope ....................................................................................................................... 1 1.2 Valley Road .............................................................................................................. 1 1.3 Average Daily Traffic Numbers ................................................................................. 1 1.4 Road Description and Comparison ........................................................................... 1 1.5 Valley Road Best Management Practices ................................................................. 2 1.6 Valley Road Assessment Conclusion ....................................................................... 3 1.7 Valley Road General Approval Standards Narrative (Article Division 107) ................ 3 2.0 CASCADE CREEK MOUNTAIN ROAD ............................................................................. 9 2.1 Scope ....................................................................................................................... 9 2.2 Mountain Road ......................................................................................................... 9 2.3 Average Daily Traffic Numbers ................................................................................. 9 2.4 Road Description and Comparison ........................................................................... 9 2.5 Mountain Road Best Management Practices ...........................................................10 2.6 Mountain Road Best Assessment Conclusion .........................................................11 2.7 Mountain Road – General Approval Standards Narrative (Article 7 Division 107) ....11 3.0 CASCADE CREEK MESA ROAD .................................................................................... 17 3.1 Scope ......................................................................................................................17 3.2 Mesa Road ..............................................................................................................17 3.3 Average Daily Traffic Numbers ................................................................................17 3.4 Road Description and Comparison ..........................................................................17 3.5 Mountain Road Best Management Practices ...........................................................18 3.6 Mountain Road Best Assessment Conclusion .........................................................19 3.7 Access Roads – Genera; Approval Standards Narrative (Article 7 Division 107) .....19 List of Tables Table 1.

The Cascade Creek Valley Road Assessment documents summarize the engineering controls and construction specifications associated with Oxy’s Cascade Creek Operating Area Valley Road which begins at the terminus of County Road 213 and extends to Oxy’s switchback 1 along the Lower Valley Floor Zone. See attached Figure 1 – Overview Map. 1.2 Valley Road Oxy’s Valley Road is a private access road existing on Oxy property to serve Oil and Gas Exploration and Production (E&P) activities. See attached Figure 2 – Valley Road. The Valley Road begins at the terminus of County Road 213 in the NE ¼ of Section 8, Township 7 South, Range 97 West of the 6th PM and terminates approximately 16,051 feet (3.04 miles) north at Oxy’s switchback 1 located in the SW ¼ of Section 21, Township 6 South, Range 97 West of the 6th PM. This roadway follows the Conn Creek drainage, gaining approximately 450 feet in elevation, and ends at a point near the confluence with the Cascade Creek drainage. The Valley Road services approximately 24 well pads and four (4) Facilities (two Compressor Stations, a Central Water Handling Facility, and one Field Office) located in the Lower Valley Floor Zone of Oxy’s Cascade Creek Operational Area. The Valley Road is used to access Oxy’s Mesa Operational area as well. The Valley Road is typical of roads providing access to natural gas production facilities, compressor stations, and Centralized E & P Facilities in Garfield County, Colorado. 1.3 Average Daily Traffic Numbers Oxy collected traffic numbers accessing Oxy’s Cascade Creek field between July 2011 and June 2012. Oxy documented traffic numbers at the Lower Guard Shack, located at the terminus of County Road 213, and at the Upper Guard Shack, located above Mountain Road switchback 6. See Figure 1 for guard shack locations. Oxy’s traffic count found an average of 148 vehicles travel the Valley Road each day. 1.4 Road Description and Comparison Oxy collected average daily traffic numbers accessing their lower guard shack and Oxy property between July 2011 and June 2012. The results of the exercise identified that Oxy had an average of 148 vehicles accessing the Valley roads each day. Based on roadway numbers collected by Oxy, the following table compares Oxy’s Valley Road to the Garfield County Roadway Standards found in Table 7-107 of the LUDC for Rural Access Roads (Table 1 below): Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 2 Table 1.

One section of the road along the entire Valley Road does not meet the Roadway Standards for lane width. This section has a width of 10.5’ per lane. Aside from this short section of road, the rest of the Valley Road meets or exceeds the required 11’ lane width. Due to the terrain and proximity to Cascade Creek, shoulders are constructed between 0 and 6 feet wide along portions of the Valley Road. Ditches are constructed throughout the Valley Road to convey water safely under the road through culverts and to dissipate as planned in Oxy’s Stormwater Management Plan. Due to the terrain of the Valley Road, majority of the ditches within the field do not comply with the required ditch width. All switchbacks along the Valley Road accommodate a minimum turning radius of 80 feet as established by the roadway standards. Oxy’s Valley Road has two roadway sections which do not meet the grade requirements of 12% due to topography in the area. 1.5 Valley Road Best Management Practices Oxy has implemented the following Best Management Practices (BMPs) to aid in providing adequate and safe access where Oxy’s Valley Road does not meet Rural Access Roadway standards.  Limit access from public and only allowing authorized personnel to utilize the road  Speed limit signs of 20 miles per hour or less. Speed limits are enforced by a private contractor throughout Oxy’s Cascade Creek area.  Uphill traffic has the right of way. This aids in reducing the amount of congestion along the roadway and allows for more efficient passage during inclement weather or busy times of the day.  Oxy conducts 14 day stormwater inspections as well as post-precipitation inspections along the entire Mountain Road. These inspections document Mountain Road and stormwater feature condition and document road maintenance issues needed for repair on a regular basis.  Oxy completes regular maintenance of the Valley Road to include grading, snow removal, maintaining stormwater BMPs, and upgrading or improvements to the roadway identified during operation. Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 3  During spring and winter, Oxy requires the use of chains on the Valley Road as a precautionary BMP. Additionally, Oxy maintains a website to allow contractors to monitor current site conditions and road alerts for requiring chains, or closed roads due to weather conditions.  During dry periods and windy events, Oxy completes dust suppression using water and chemical suppressant (i.e. magnesium chloride) spreading to ensure safe visibility is not impaired during wind events. Details on dust controls are provided in Oxy’s Dust Management Plan, located in the Standards Tab. 1.6 Valley Road Assessment Conclusion Given the on-going construction and maintenance activities completed by DIA Construction, BMP implementation and maintenance completed by DIA Construction and McIntyre Construction, and vehicle traffic volumes, Oxy has provided safe and adequate access to Oxy’s employees and contractors utilizing the Valley Road. 1.7 Valley Road General Approval Standards Narrative (Article Division 107) 1.7.1 Introduction The following section addresses the requirements for the General Approval Standards under Article 7, Division 107 of the Garfield County Land Use and Development Code (LUDC). 1.7.2 Access to Public Right-of-Way All lots and parcels shall have legal and physical access to a public right-of-way.

Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 9 2.0 CASCADE CREEK MOUNTAIN ROAD 2.1 Scope According to the Garfield County Land Use and Development Code (LUDC) Section 7-107 – Access and Roadways, all roads are required to be designed to provide “adequate and safe access” and reviewed by the designated County Engineer. The Cascade Creek Mountain Road Assessment documents summarize the engineering controls and construction specifications associated with Oxy’s Cascade Creek Operating Area Mountain Road which begins below Oxy’s switchback 1 and travels up the Talus and Escarpment Zones to Oxy’s switchback 6, see Figure 1.– Overview Map. 2.2 Mountain Road Oxy’s Mountain Road is a private access road existing on Oxy property to serve Oil and Gas Exploration and Production activities, see Figure 1. Oxy’s Mountain Road begins southwest of Oxy’s switchback 1 in the SW ¼ of Section 20, Township 6 South, Range 97 West of the 6 th PM and terminates northeast of switchback 6 in the SE ¼ of Section 21, Township 6 South, Range 97 West, 6th PM. The Mountain Road is approximately 19,958 feet (3.78 miles) long and traverses the Talus Zone and Escarpment Zone with an elevation change of approximately 2,000 feet to access Oxy’s Mesa operational area within the Plateau Zone. The Mountain Road allows for the service of currently 32 well pads, six water storage facilities, and one storage area within Oxy’s Mesa operational area. This roadway is typical of roads traversing the Talus and Escarpment Zones providing access to natural gas production facilities and Centralized Exploration and Production Facilities within the Plateau Zones located in Garfield County, Colorado. 2.3 Average Daily Traffic Numbers Oxy collected traffic numbers accessing Oxy’s Cascade Creek field between July 2011 and June 2012. Oxy documented traffic numbers at the Lower Guard Shack, located at the terminus of County Road 213, and at the Upper Guard Shack, located above Mountain Road switchback 6, see Figure 1 for guard shack locations. Oxy’s traffic count found an average of 120 vehicles travel the Mountain Road each day. 2.4 Road Description and Comparison The following table compares Oxy’s Mountain Road to the Garfield County Roadway Standards found in Table 7-107 of the LUDC for Rural Access Roads (Table 3 below): Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 10 Table 3. Table 7-107 of the LUDC for Rural Access Roads – Mountain Road Table 7-107: Roadway Standards Design Standards Rural Access Road Mountain Road Design Capacity (ADT) 101-200 120 Minimum ROW Width (Feet) 50 N/A Lane Width (Feet) 11 9.9 to >12 Shoulder Width (Feet) 4, 2 min. paved 0 – 20 Ditch Width (Feet) 6 1 – 4 Cross Slope 2% chip/seal, 3% gravel 2% Shoulder Slope 5% 2% Design Speed n/a n/a Minimum Radius (Feet) 80 52, 54, and >80 Maximum % Grade 12% 5 – 13% Surface Gravel Native Material/Gravel Based on the 2011 and 2012 roadway numbers collected by Oxy, the Average Daily Traffic (ADT) for the Mountain Road is expected to be approximately 120 vehicles per day. Oxy’s Mountain Road is located on private property and therefore is not located within a ROW. One section of the road along the entire Mountain Road does not meet the Roadway Standards for lane width. This section has a width of 9.9’ per lane. Aside from this short section of road, the rest of the Mountain Road meets or exceeds the required 11’ lane width. Due to the topography along the mountain road, the shoulder width along the road ranges from 0 – 20 feet. Although not found on the entire Mountain Road, shoulder sections are found along portions of the Mountain Road ensuring the roadway does not become congested within sections of the road. Based on terrain of the road, ditches are constructed on the inside lane of the entire Mountain Road to manage stormwater on the roadway. These ditches convey the stormwater into culverts which pass under Oxy’s Mountain Road and dissipate down the hillside. Two of the six switchbacks as part of Oxy’s Mountain Road do not accommodate a minimum turning radius of 80 feet as required by the Rural Access Roadway Standards. These locations are Oxy’s switchback 2 with a turning radius of 52’ and Oxy’s switchback 6 with a turning radius of 54’. Oxy’s Mountain Road grade ranges from 5% to 13%, as compared to the Rural Access Roadway standard requiring a maximum grade of 12%. Within the Mountain Road, only one roadway section does not meet the grade requirements of the Rural Access Roadway Standards. 2.5 Mountain Road Best Management Practices Oxy has implemented the following Best Management Practices (BMPs) to aid in providing adequate and safe access where Oxy’s Mountain Road does not meet Secondary Access Roadway standards. The following signage is posted along the Mountain Road:  Limit access from public and only allowing authorized personnel to utilize the road  Speed limit signs of 20 miles per hour or less. Speed limits are enforced by a private contractor throughout Oxy’s Cascade Creek area.  Switchback number signage to aid in roadway identification  Uphill traffic has the right of way. This aids in reducing the amount of congestion along the roadway and allows for more efficient passage during inclement weather or busy times of the day. Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 11  Through most of the Mountain Road, Oxy has installed Jersey barriers or Hesco barriers along the outside edge of the road to aid in safe passage. These sections of barriers are mainly installed through less visible, narrow, or steep sections of road. The entire road is not edged with barriers to allow for snow removal and blading operations to have adequate locations for snow and gravel storage.  Oxy conducts 14 day stormwater inspections as well as post-precipitation inspections along the entire Mountain Road. These inspections document Mountain Road and stormwater feature condition and document road maintenance issues needed for repair on a regular basis.  Oxy completes regular maintenance of the Mountain Road to include grading, snow removal, maintaining stormwater BMPs, and upgrading or improvements to the roadway identified during operation.  During spring and winter, Oxy requires the use of chains on the Mountain Road as a precautionary BMP. Additionally, Oxy maintains a website to allow contractors to monitor current site conditions and road alerts for requiring chains, or closed roads due to weather conditions.  During dry periods and windy events, Oxy completes dust suppression using water and chemical suppressant (i.e. magnesium chloride) spreading to ensure safe visibility is not impaired during wind events. Details on dust controls are provided in Oxy’s Dust Management Plan, located in the 604-12-13 Storage Site and 697-16-16 Storage Site submittal. 2.6 Mountain Road Best Assessment Conclusion Given the on-going construction and maintenance activities completed by DIA Construction, BMP implementation and maintenance completed by DIA Construction and McIntyre Construction, and vehicle traffic volumes, Oxy has provided safe and adequate access to Oxy’s employees and contractors utilizing the Mountain Road. 2.7 Mountain Road – General Approval Standards Narrative (Article 7 Division 107) 2.7.1 Introduction The following section addresses the requirements for the General Approval Standards under Article 7, Division 107 of the Garfield County Land Use and Development Code (LUDC). 2.7.2 Access to Public Right-of-Way All lots and parcels shall have legal and physical access to a public right-of-way.

The Cascade Creek Mesa Road Assessment documents summarize the engineering controls and construction specifications associated with Oxy’s Cascade Creek Operating Area Mesa Road which begins at Oxy’s switchback 6 and travels the Plateau Zone to Oxy’s 604-12-13 Storage Site and 697-16-16 Storage Site, see Figure 1– Overview Map. 3.2 Mesa Road Oxy’s Mesa Road is a private access road existing on Oxy property to serve Oil and Gas Exploration and Production activities, see Figure 1. Oxy’s Mesa Road begins northeast of switchback 6 in the SE ¼ of Section 21, Township 6 South, Range 97 West, 6th PM and terminates at the entrance of the 604-12-13 Storage Site and 697-16-16 Storage Site facility located in the NE ¼ of the SE ¼ of Section 4, Township 6 South, Range 97 West, 6th PM. The Mesa Road is approximately 43,010 feet (8.15 miles) long and traverses the Plateau Zone to access the site. The Mesa Road allows for the service of currently 38 well pads, six water storage facilities, and one storage area within Oxy’s Mesa operational area. This roadway is typical of roads traversing the Plateau Zone providing access to natural gas production facilities and Centralized Exploration and Production Facilities within the Plateau Zone located in Garfield County, Colorado. 3.3 Average Daily Traffic Numbers Oxy collected traffic numbers accessing Oxy’s Cascade Creek field between July 2011 and June 2012. Oxy documented traffic numbers at the Lower Guard Shack, located at the terminus of County Road 213, and at the Upper Guard Shack, located above Mountain Road switchback 6, see Figure 1 for guard shack locations. Oxy’s traffic count found an average of 120 vehicles travel the Mesa Road each day. 3.4 Road Description and Comparison The following table compares Oxy’s Mesa Road to the Garfield County Roadway Standards found in Table 7-107 of the LUDC for Rural Access Roads (Table 3 below): Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 18 Table 5. Table 7-107 of the LUDC for Rural Access Roads – Mesa Road Table 7-107: Roadway Standards Design Standards Rural Access Road Mesa Road Design Capacity (ADT) 101-200 120 Minimum ROW Width (Feet) 50 N/A Lane Width (Feet) 11 9.9 to >12 Shoulder Width (Feet) 4, 2 min. paved 0 – 10 Ditch Width (Feet) 6 1 – 4 Cross Slope 2% chip/seal, 3% gravel <2%% Shoulder Slope 5% 0 to <5% Design Speed n/a 25 MPH Minimum Radius (Feet) 80 >80 Maximum % Grade 12% <12%, except 5 sections Surface Gravel Native Material/Gravel Based on the 2011 and 2012 roadway numbers collected by Oxy, the Average Daily Traffic (ADT) for the Mesa Road is expected to be approximately 120 vehicles per day. Oxy’s Mesa Road is located on private property and therefore is not located within a ROW. Four sections along the entire Mesa Road do not meet the Roadway Standards for lane width. Aside from these short sections of road, the rest of the Mesa Road meets or exceeds the required 11’ lane width. Due to the topography along the Mesa Road, the shoulder width along the road ranges from 0 – 10 feet. Although not found on the entire Mesa Road, shoulder sections are found along portions of the Mesa Road ensuring the roadway does not become congested within sections of the road. Based on terrain of the road, ditches are constructed on at least one side of the Mesa Road to manage stormwater on the roadway. These ditches convey the stormwater into culverts which dissipate stormwater away from the roadway. All switchbacks associated with the Mesa Road access to 604-12-13 Storage Site and 697-16-16 Storage Site accommodate a minimum turning radius of 80 feet as required by the Rural Access Roadway Standards. Except for five sections, Oxy’s Mountain Road grade meets the maximum grade requirement of Rural Access roads of 12%. 3.5 Mountain Road Best Management Practices Oxy has implemented the following Best Management Practices (BMPs) to aid in providing adequate and safe access where Oxy’s Mesa Road does not meet Secondary Access Roadway standards:  Limit access from public and only allowing authorized personnel to utilize the road  Speed limit signs of 20 miles per hour or less. Speed limits are enforced by a private contractor throughout Oxy’s Cascade Creek area.  Uphill traffic has the right of way. This aids in reducing the amount of congestion along the roadway and allows for more efficient passage during inclement weather or busy times of the day.  Oxy conducts 14 day stormwater inspections as well as post-precipitation inspections along the entire Mesa Road. These inspections document Mesa Road and stormwater feature condition and document road maintenance issues needed for repair on a regular basis. Garfield County Roadway Standards Assessment Oxy USA WTP LP 013-0655 January 2015 19  Oxy completes regular maintenance of the Mesa Road to include grading, snow removal, maintaining stormwater BMPs, and upgrading or improvements to the roadway identified during operation.  During spring and winter, Oxy requires the use of chains on the Mesa Road as a precautionary BMP. Additionally, Oxy maintains a website to allow contractors to monitor current site conditions and road alerts for requiring chains, or closed roads due to weather conditions.  During dry periods and windy events, Oxy completes dust suppression using water and chemical suppressant (i.e. magnesium chloride) spreading to ensure safe visibility is not impaired during wind events. Details on dust controls are provided in Oxy’s Dust Management Plan, located in the 604-12-13 Storage Site and 697-16-16 Storage Site submittal. 3.6 Mountain Road Best Assessment Conclusion Given the on-going construction and maintenance activities completed by DIA Construction, BMP implementation and maintenance completed by DIA Construction and McIntyre Construction, and vehicle traffic volumes, Oxy has provided safe and adequate access to Oxy’s employees and contractors utilizing the Mesa Road. 3.7 Access Roads – Genera; Approval Standards Narrative (Article 7 Division 107) 3.7.1 Introduction The following section addresses the requirements for the General Approval Standards under Article 7, Division 107 of the Garfield County Land Use and Development Code (LUDC). 3.7.2 Access to Public Right-of-Way All lots and parcels shall have legal and physical access to a public right-of-way.
