Subject: National Historic Preservation Act Section 106 Consultation - McElmo 

Creek Unit Oil Production Facility, San Juan County, Utah 

Dear Ms. Marek-Martinez: 

In accordance with Section 106 of the National Historic Preservation Act (NHP A) and its 

implementing regulations, 36 CFR Part 800, we are providing information for your review and 

concurrence regarding the project referred to in the paragraph below. EPA is the lead federal 

agency for the issuance of an amended Prevention of Significant Deterioration (PSD) air quality 

permit in the Navajo Nation Reservation. We have made a finding of "No Historic Properties 

Affected" for this undertaking pursuant to 36 CFR 800.4(d)(l). 

The United States Environmental Protection Agency, Region 9 (EPA) is reviewing an 

application for the issuance of an amended PSD air quality permit, in accordance with the Clean 

Air Act and the PSD air quality regulations (40 CFR 52.21), for the gas flare (called the "Main 

Flare") at the McElmo Creek Unit Oil Production Facility (MCU Facility), an existing oil and 

gas production operation. Other than the potential replacement of an existing fan to provide 

better pollution control at the Main Flare, EPA' s issuance of the amended PSD permit does not 

authorize any new construction or modification of existing equipment at the MCU Facility. 

Additionally, EPA is amending the permit to remove certain equipment, and the applicable 

permit requirements that apply because this equipment has been shut down and removed from 

the site. 

In consultation with the Navajo Nation Historic Preservation Department, the area of potential 

effects (APE) for this project consists of an area within a 2 km (1.2 miles) radius around the 

Main Flare. Resolute Natural Resources, LLC, contracted with Dinetahd66 Cultural Resources 

Management (DCRM) to conduct an assessment to identify historic properties within the APE (2 

km around the Main Flare). Resolute provided DCRM's final assessment of historic properties 

to EPA on September 2, 2015 (September 2015 DCRM Report enclosed). 
Based on all of the information provided and after careful review and analysis, EPA has 

determined that issuance of the amended PSD Permit for the Main Flare will have no effect upon 

historic properties within the APE. 

EPA requests that you review the enclosed Project Description Summary and concur on our 

determination that no historic properties will be affected by EPA' s undertaking. Please inform 

us within 30 days if you concur with our proposed determination. If you do not reply within this 

30 day review period, EPA will consider the lack of reply to be Navajo Nation Historic 

Preservation Department agreement with the determination. 

If you have any questions or need further information, please contact Shaheerah Kelly at 

(415) 947-4156. Thank you for your assistance and consideration in this matter.

Proposed Amended Clean Air Act Prevention of Significant Deterioration Permit 

PSD Permit No. NU 05-01

September 30, 2015

INTRODUCTION

The United States Environmental Protection Agency, Region 9 (EPA) is acting on an application 

for an amendment to a Clean Air Act Prevention of Significant Deterioration (PSD) air quality 

permit, in accordance with the Clean Air Act and the PSD air quality regulations (40 CFR 

52.21), for the gas flare (called the “Main Flare”) at the McElmo Creek Unit Oil Production 

Facility (MCU Facility or Facility), an existing oil and gas production operation. Pursuant to 

Section 106 of the National Historic Preservation Act (NHPA), 54 U.S.C. §100101 et seq., and 

its implementing regulations at 36 CFR Part 800, prior to issuing the permit amendment, EPA is 

required to take into account the effects of its undertaking (e.g. issuance of a permit amendment)

on historic properties listed in or eligible for inclusion in the National Register of Historic Places. 

Consultation with the State Historic Preservation Officer and/or the Tribal Historic Preservation 

Officer 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 effects (APE) and, 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 Historic Places 

maintained by the Department of the Interior. The EPA is the lead federal agency for this 

undertaking. As such, EPA must meet its NHPA Section 106 obligations for this project prior to 

issuing a final permit decision.

DESCRIPTION OF THE UNDERTAKING

EPA’s undertaking, as defined in 36 CFR 800.16(y) and which triggers the application of the 

NHPA, is the issuance of an amended PSD air quality permit (PSD Permit) for 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, EPA’s action is focuses on the 

existing Main Flare, which is used to control pollution from the operation of the MCU Facility. 
NHPA Cultural Resources Summary

Page 2

The MCU Facility is located in Section 31, Township 40 South, Range 25 East within the Four 

Corners area on the Navajo Nation Reservation near the city of Aneth, San Juan County, Utah.

(See Figure 1.) The MCU Facility is also located on the McElmo Creek Unit oilfield, which is 

one of four oilfield units in the greater Aneth oilfield on the Navajo Nation Reservation in 

southeastern Utah. (See Figure 2.)

Figure 1: Location of McElmo Creek Unit Oil Production Facility

The MCU Facility started operation in the 1950s and was owned by Superior Oil at the time. 

Mobil Exploration and Producing U.S. Inc. (Mobil) purchased the Facility in 1984. Resolute 

Natural Resources Company (Resolute), in partnership with Navajo Nation Oil and Gas 

Company, acquired Mobil’s ownership interest in April 2006 and assumed operation of the 

Facility on June 1, 2006. 

The field operations located on the McElmo Creek Unit oilfield consist of approximately 90 

producing wells where petroleum crude oil is recovered from producing strata, brought to the

surface to be stored at either a satellite or a tank battery. There are eleven satellites that function 

as testing facilities for producing wells and four tank batteries. The gas compression plant is 

used to support tertiary recovery of crude oil in the McElmo Creek Unit oilfield, and includes the 

Main Flare. 

EPA’s PSD Permit action is to incorporate 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) for the Main Flare at the MCU Facility’s gas compression plant. 

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.

Additionally, EPA is amending the permit to remove certain equipment, and the applicable 

permit requirements that apply because this equipment has been shut down and removed from 

the site. Other than the potential replacement of an existing fan to provide better pollution control 

at the Main Flare, EPA’s amendments to the PSD permit do not authorize any new construction 

or modification of existing equipment at the MCU Facility.

On October 15, 2014, EPA issued the amended PSD Permit for public comment. A final permit 

decision will be issued following completion of the Agency’s NHPA Section 106 consultation

process.

AREA OF POTENTIAL EFFECTS

Since the EPA’s permit action does not authorize any new construction or modification of 

existing equipment at the MCU Facility, other than potential replacement of an existing fan at the 

Main Flare, this action is not expected to result in any new ground disturbance or change in 

operations at the MCU Facility. As such, in consultation with the Navajo Nation Historic 

Preservation Department (NNHPD), the APE for this project consists of an area within a 2 km 

(1.2 miles) radius around the Main Flare as shown in Figure 3.

properties, dated September 2, 2015 (DCRM Report), is provided as an attachment to this 

Cultural Resources Report document. 

Prior to conducting the fieldwork, DCRM examined records at the NNHPD office in Window 

Rock, Arizona, to determine whether cultural resources inventories had been performed within 

the project area. DCRM identified fifty (50) previously recorded archaeological sites within the 

APE based upon a literature search conducted at the NNHPD records room. These specific sites 

are described in the DCRM Report. None of these sites were determined to be listed in the 

National Register of Historic Places maintained by the Department of the Interior. Under the 

NHPA Section 106 and 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 

location, design, setting, material, workmanship, feeling, and association.” 

Between May 21, 2015 and June 3, 2015, DCRM conducted fieldwork which consisted of 

cultural resource assessments of the historic and in-use properties within the APE. DCRM 

identified and evaluated thirteen (13) historic structures and nine (9) in-use sites. These specific 

historic structures and in-use sites are provided in the DCRM Report. None of these sites were 

determined to be in the National Register of Historic Places maintained by the Department of the 

Interior. 

CONCLUSION

Based on the accompanying information and the opinions already offered by the NNHPD 

regarding this project, EPA has determined that issuance of the amended PSD Permit for the 

Main Flare will have no effect upon historic properties within the APE.

Introduction

Between May 21 and June 3, 2015, Jeremy Begay, Clifford Werito, Shane Wero, Natasha 

Ignacio, and Jeffrey Begay, archaeologists with 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 search in the Navajo Nation Historic Preservation Department’s 

records room, which identified fifty previously documented archaeological sites. This work was 

conducted to fulfill NHPA requirements as requested by the U.S. Environmental Protection 

Agency, Region 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). 

Pursuant 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 and, 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 

Historic 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 the 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 incorporate 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 and 
2

removed from the site. Other than the potential replacement of a fixed speed fan with a variable 

speed 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

The project area is in San Juan County, Utah, on Navajo Nation Trust lands in the Aneth Chapter

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 resources 

inventories had been performed within the project area. The review indicated that numerous

large and small projects have been conducted within the project area, with fifty previously 

identified archaeological sites being recorded. Table 2 provides the site 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 Valley 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-grained 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. Prevalent flora in the area include

cottonwood, tamarisk, Russian olive, elm, cheat, brome, and grama grass, ring muhly, Russian 

thistle, prickly pear and cholla cacti, snakeweed, rabbitbrush, 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 led to the incorporation of the Utah Navajo lands into the Navajo 

Reservation. There is extensive oil industry development in the Aneth area (LSR Innovations 

2004).

Field Methods

Between May 21 and June 3, 2015, Jeremy Begay, Clifford Werito, Shane Wero, Natasha 

Ignacio, and Jeffrey Begay, archaeologists with Dinétahdóó Cultural Resources Management 

(DCRM), conducted the cultural resources 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 visited, including interviews with the residents and/or employees

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 recorded using a handheld Global Positioning Satellite (GPS) unit. 

Cultural Resources Findings

Thirteen 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 previously documented 

archaeological sites was not conducted. The 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-42-48 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 CO2 pipeline project. 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 remnants 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 characteristics attributable to Archaic traditions.

In-Use Sites

During the survey, nine in-use sites (IUSs) were identified and recorded. Five are Navajo 

extended family communities and four are Resolute 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. The 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 regarding 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 1950s. The original home was constructed from shaped sandstone that was 

quarried from a nearby sandstone source. An addition was added to the home in the 1980s. 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 1950s. 

Modern materials were used to construct the home. The house is L-shaped and has a cement 

porch on the north side. The home is presently unoccupied and is slowly deteriorating. 
25

Stone Historic House (Structure 3). The home was originally constructed in the late 1920s by 

Curley John and Big John. The materials for the home were quarried from a sandstone source 

nearby and transported by a wheelbarrow. The home is currently unoccupied. 

Historic House (Ruin) (Structure 4). The home was originally built in the 1930s 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. The home is unoccupied. 
26

Structures Recorded in IUS 2

Historic Shed (Structure 5). This shed was built in the late 1950s by Harry Todacheenie. The 

shed was primarily used for storing tools and equipment for the Todacheenie family. The shed is 

still in use. 

Historic Home (Desirae Todacheenie) (Structure 6). This home belongs to Desirae 

Todacheenie and was originally built in the late 1950s 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 1950s

by Harry Todacheenie and Harold Benally. The home features a stone wall and fenced yard. 

Another addition is being planned. Currently, the home is under construction and is occupied by 

Ms. June Benally. 

Historic Home (Dora Todacheenie) (Structure 8). This home was originally constructed in the 

late 1950s 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 

DCRM 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 overlooks 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. Both 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 rebar. 

Evaluation of Significance

All cultural resources identified and recorded are evaluated for significance under certain federal 

statutes for the preservation 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 location, 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 distinguishable 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; properties 

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 significance 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.

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.
