### Introduction Between May 2 1 and June 3 , 2015, Jeremy Begay, Clifford Werito, Shane Wero, Natasha Ignacio, and Jeffrey Begay, archaeologists wit h Dinétahdóó Cultural Resources Management (DCRM), conducted a field assessment of nine in - use sites and thirteen historic structures within 2 km of Resolute Natural Resources’ McElmo Creek Unit in San Juan County, Utah. DCRM also conducted a literature se arch in the Navajo Nation Historic Preservation Department’s records room , which identified fifty previously documented archaeological sites . Th is work was conducted to fulfill NHPA requirements as requested by the U.S. Environmental Protection Agency, Reg ion 9 , for the undertaking . This cultural resources inventory was completed under the Navajo Nation Historic Preservation Department permit number B14288 . Description of Undertaking Resolute Natural Resources, LLC contracted with DCRM to identify historic properties, as defined by the National Historic Preservation Act (NHPA) and its implementing regulations, within a 2 km Area of Potential Effect (APE) of the main flare at the McElmo Creek Unit Oil Production Facility (MCU Facility or Facility). Pursuan t to Section 106 of the NHPA, and its implementing regulations at 36 CFR Part 800, prior to the approval of the expenditure of any funds on or prior to the issuance of any license for an undertaking, EPA is required to take into account the effects of its undertakings on historic properties. Consultation is required for all undertakings that have the potential to affect historic properties. Section 106 consultations assess whether historic properties exist within an undertaking’s area of potential effect an d, if so, whether the undertaking will adversely affect such properties. The term “historic properties” means prehistoric or historic districts, sites, buildings, structures, or objects included in, or eligible for inclusion in, the National Register of Hi storic Places maintained by the Department of the Interior. EPA’s undertaking triggering the application of the NHPA is the issuance of a federal Prevention of Significant Deterioration (PSD) air quality permit, in accordance with the Clean Air Act and PSD regulations (40 CFR 52.21), for the gas flare (called the “main flare”) at the MCU Facility. While the Facility is an existing oil and gas production operation located on the McElmo Creek Unit oilfield in San Juan County, Utah, our action is only for t he gas flare which is used to destroy natural gas during any upsets of the natural gas gathering system. The United States Environmental Protection Agency (EPA) Region 9 is the lead federal agency for this undertaking. EPA is amending the PSD permit to i ncorporate pollution limits, terms, and conditions of a federal Consent Decree (United States v. Mobil Exploration and Producing U.S. Inc., Case No. 2:05 - CV - 319, filed June 8, 2005) that specifically applies to the main gas flare at the MCU Facility. These pollution limits, terms, and conditions include Best Available Control Technology (BACT) emission limitations for nitrogen oxides, carbon monoxide, sulfur dioxide, and volatile organic compounds for the main flare at the MCU Facility . Additionally, EPA is amending the PSD permit to remove and update other applicable requirements in the MCU Facility’s PSD permit due to equipment that has been shut down and2 

### removed from the site. Other than the potential replacement of a fixed speed fan with a variable spe ed fan to provide better pollution control at the already existing main flare, EPA’s action does not authorize any new construction or modification of existing equipment at the MCU Facility. EPA issued the proposed permit for public comment on October 15, 2014. A final permit decision will be issued following completion of the Agency’s Section 106 NHPA consultation. DCRM’s identification of historic properties included a literature search to identify previously recorded cultural resources to determine if they qualified as historic properties under the NHPA (Figure 1) as well as a field assessment of existing Navajo in - use sites within the APE to determine if any of the structures are eligible for listing as historic properties (Figure 2) . Location Th e project area is in San Juan County, Utah , on Navajo Nation Trust lands in the Aneth Chapter ( Figure 1 ) .

### Existing Data Review Prior to the fieldwork, a records check was conducted at the Navajo Nation Historic Preservation Department (NNHPD) in Window Rock, Arizona , to determine whether cultural resourc es inventories had been performed within the project area . The review indicated that numerous large and small project s ha ve been conducted within the project area , with fifty previously identified archaeological site s being recorded . Table 2 provides the s ite designation, type, and report in which the archaeological site was documented.

### Environmental and Cultural Setting The San Juan River is a braided channel system that serves as the main drainage for the San Juan Basin. Within the San Juan V alley are Navajo communities such as Upper Fruitland, Shiprock, Teec Nos Pos, and Aneth. The large, flat bottomed valley is incising numerous Cenozoic era geologic facies. Large sedimentary and igneous clasts ranging from pebbles to boulders have been deposited in the San River Valley from the nearby San Juan igneous belt to the north . Eons of erosion have created numerous named and unnamed secondary geologic and geographic features such as side tributaries, escarpments, terraces, hills, and floodplains. Surface sediments within the area consist of fine - to coarse - grai ned alluvial, fluvial, colluvial, aeolian, and residual packages of sand, silt, clay, and multi - lithic sand. The river, which flows year - round, supports a wide variety of native, cultivated, and foreign plant species. P revalent flora in the area include co ttonwood, tamarisk, Russian olive, elm, cheat, brome, and grama grass, ring muhly, Russian thistle, prickly pear and cholla cacti, snakeweed, rabbit brush, and tansy mustard. The Navajo name for Aneth is Taa’ biich’ iidii, which means “ Just like the devil , ” a name applied to the community’s first Anglo trader because of his business practices. Several land agreements and exchanges le d to the incorporation of the Utah Navajo lands in to the Navajo Reservation. There is extensive oil industry development in th e Aneth area (LSR Innovations 2004). Field Methods Between May 21 and June 3 , 2015, Jeremy Begay, Clifford Werito, Shane Wero, Natasha Ignacio, and J effrey Begay , archaeologists with Dinétahdóó Cultural Resources Management (DCRM) , conducted the cultural r esources assessments of the historic and in - use properties in the project area . As described below, the previously recorded archaeological sites were not field reassessed. Historic Structure Identification and Inventory Nine currently in - use sites were vi sited , including interviews with the residents and/or empl o yees regarding the age and cultural importance of structures that are at least 50 years old and that were deemed potentially eligible for protection under Section 106 guidelines. Thirteen historic structures were identified during the inventory. Interviews with the owners of the historic structures provided information regarding the importance and history of the structure.7 

### Locations of the cultural resources identified during the inventory were rec orded using a hand held Global Positioning Satellite (GPS) unit. Cultural Resources Findings T hirt een historic structures and nine in - use sites were documented during the inventory and are described in this section . An in - field assessment of the fifty pre viously documented archaeological sites was not conducted. T he information provided in this report was collected during the literature search at the NNHPD records room and reflects the description and assessments made by the earlier recording. Information on thirty - nine sites was found; the remaining eleven previously identified archaeological sites had no documentation .

### Site Description: UT - C - 42 - 4 0 is an undated lithic scatter that was originally recorded in 1985 by Navajo Nation Archaeology Department (NNAD) archaeologists. The 1985 NNAD survey recorded a scattering of flaked lithic artifacts including a scraper tool. No other features or ar tificats were recorded. No diagnostic artifacts were observed, however, sites that contain this sort of artifact assemblage are usually attributed to Archaic groups.

Site Description: UT - C - 42 - 48 is an Archaic artifact scatter that was originally recorded in 1985 by NNAD archaeologists. The site was last visited in 1997 by Complete Archaeological Service Associates (CASA) archaeologists in conjunction with a CO 2 

### pipeline pr oject. The 1985 NNAD survey recorded a scattering of flaked lithic artifacts and several sandstone slab piles that were attributed to the prehistoric Archaic occupation. In the 1997 survey, CASA archaeologists determined that the sandstone piles were remna nts of oil field activity and that the majority of the artifacts recorded by the NNAD archaeologists had since been redeposited by various oil field activities , and that very few artifacts remained in situ. A single broken projectile point base contained c haracteristics attributable to Archaic traditions.

In 1994, NNAD archaeologists reported that UT - C - 42 - 104 had been heavily damaged when heavy vehicles had been used to remove soil in the site area for use elsewhere. These activities had severely disturbed and even destroyed several of the hearths. Nevertheless, the NNAD archaeologists believed that UT - C - 42 - 104 may contain subsurface cultural deposits in the undamaged areas.

Site Description: UT - C - 55 - 163 is a historic Navajo corral and lambing pen recorded in 1993 by NNAD archaeo logists in conjunction with a road survey. Many of the corral walls incorporated sandstone boulders. Two crushed metal cans were observed within the corral , which was dated to 1909 by ethnographic interviews. The lambing pen is south of the main corral and was22 

### constructed using dry laid sandstone blocks and slabs. No other features or artifacts were recorded. In - Use Sites During the survey, nine 

### in - use sites (IUS s ) were identified and recorded . F ive are Navajo extended family communities and four are Resol ute Natural Resources facilities. Also, in accordance with Navajo Nation Historic Preservation Department policies, the project archaeologists interviewed several Navajo residents about any traditional cultural properties or unmarked burials in the area. T he interviews were conducted in English and Navajo. A brief description of the identified IUSs and the interview results can be found in Table 3.

### Historic Structures Thirteen structures were identified as being historic and eligible for listing as historic properties according to the NHPA. DCRM archaeologists, through ethnographic interviews, obtained information re garding the structures and their importance to the residents to whom they belong. Information regarding the thirteen historically significant structures can be found below.24 

### Structures recorded in IUS 1 Modern/Historic House (Structure 1 ) . This home was constructed by Big John and Curley John in the early 195 0s . The original home was constructed from shaped sandstone that was quarried f rom a nearby sandstone source. A n addition was added to the home in the 198 0s . The home is still in - use and is occupied by the Anna B. Oldman family.

Pink Historic House (Structure 2) . The home was constructed by Big John in the late 195 0s . Modern materials were used to construct the home. The house is L - shaped and has a cement porch on the north side. T he home is presently unoccupied and is slowly deteriorating.25 

### Stone Historic House (Structure 3) . The home was originally constructed in the late 192 0s by Curley John and Big John. The materials for the home were quarried from a sandstone source nearb y and transported by a wheelbarrow. The home is currently unoccupied.

Historic House (Ruin) (Structure 4) . The home was originally built in the 193 0s by Big John and Tom Skeezie. As with the other stone structures, the materials were quarried from a nearby sandstone source and transported by wheelbarrow ; only the north wall and half of the east wall are still standing. Some fruit trees are still growing on the north side. T he home is unoccupied.26 

### Structures R ecorded in IUS 2 Historic Shed (Struct ure 5 ) . This shed was built in the late 195 0s by Harry Todacheenie. The shed was primarily used for storing tools and equipment for the Todacheenie family. T he shed is still in use.

Historic Home (Desirae Todacheenie) (Structure 6 ) . This home belongs to Desirae Todacheenie and was originally built in the late 195 0s by Harry Todacheenie and Harold Benally. The original home was smaller, but recent additions have increased the size of the home. The home is currently occupied by Ms. Desirae Todacheenie.27 

### Historic Home (June Benally) (Structure 7 ) . This home was originally built in the late 195 0s by Harry Todacheenie and Harold Benally. The home features a stone wall and fenced yard. A nother addition is being planned. Currently, the home is under const ruction and is occupied by Ms. June Benally.

Historic Home (Dora Todacheenie) (Structure 8 ) . This home was originally constructed in the late 195 0s by Harry Todacheenie and Harold Benally. This home features a stone wall and there are recent additions to the home. The home is currently occupied by Ms. Dora Todacheenie and Ms. Clara Todacheenie.28 

### Traditional Cultural Properties Although the identification of Traditional Cultural Properties was not an objective of the current undertaking, interviews with Navajo residents occupying the in - use residential sites provided data about four areas of traditional and cultural concern. These four Traditional Cultural Properties (TCPs) are two natural springs and two offering areas. Information gathered by the D CRM ethnographic inquiry for the four TCPs can be found in Confidential Appendix B. Sweathouse #1 (Structure 5). This in - use sweathouse is used by the Anna B. Oldman family. The Plains - style sweathouse is made from tamarisk shafts bent over to make a dome that can be covered by a tarp or hides. In the middle of the sweathouse is a hollow pit where the heated rocks are placed. Near the sweathouse is a storage shelter and a cache of volcanic rocks for heating. The sweathouse is located on a ledge that overlo oks the western horizon. The sweathouse is still in use by the Oldman family. No photographs were taken. Corral #1 and Corral #2 (Structures 6 & 7). These corrals are located at IUS #1 and belong to the Anna B. Oldman family and the Emma Benally family. B oth corrals have been blessed and are currently in use. Corral #3 and Corral #4 (Structures 12 & 13) . These in - use corrals belong to the Todacheenie family. These corrals were first constructed in the late 1950s. The corrals have been blessed and contain birth cords from Harold Benally’s two sons. The corrals are made from scrap pieces of lumber and iron re bar. Evaluation of Significance All cultural resources identified and recorded are evaluated for significance under certain federal statutes for the p reservation and management of these resources. This process is intended to ensure that cultural resources are not inadvertently destroyed, and to ensure that local communities are involved in the decision - making process. The National Historic Preservation Act Under the Section 106 process of the National Historic Preservation Act (NHPA; 36 CFR 60.4), cultural resources may be eligible for nomination to the National Register of Historic Places if they are more than 50 years old and “possess integrity of loc ation, design, setting, material, workmanship, feeling, and association.” One or more of the following criteria (a - d) must be applicable: a. associated with events that have made a significant contribution to the broad patterns of our history; or b. associated with the lives of a person significant in our past; or c. embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and d istinguishable entity whose components may lack individual distinction; or d. has yielded, or may be likely to yield, information important in prehistory or history.29 

### As defined in 36 CFR 60.4, cemeteries, birthplaces, or graves of historical figures; proper ties owned by religious institutions or used for religious purposes; structures that have been moved from their original locations; reconstructed historical buildings; properties primarily commemorative in nature; and properties that have achieved signific ance within the past 50 years are not ordinarily considered eligible for the National Register. However, such properties may qualify if they are integral parts of districts that do meet the eligibility criteria.

### Impact of the Undertaking on Historical Properties EPA’s undertaking does not authorize any new construction or modification of existing equipment at the MCU Facility. The undertaking results in no new surface disturbance or change in operations and therefore will have no effect on eligible historic properties located within 2 km APE for the McElmo Creek Unit main flare.36
