environmental properties management. LLC May 6, 2016 Ms. Hillary Young Chief Environmental Engineer Oklahoma Department of Environmental Quality 707 North Robinson Oklahoma City, OK 73102 Re: Cimarron Environmental Response Trust Approval to Inject Treated Water Under Oklahoma's UIC Program
Dear Ms. Young:
Environmental Properties Management LLC (EPM) is the Trustee for the Cimarron Environmental Response Trust, which owns the former nuclear fuel production facility located in Logan County, OK. In December 2015, EPM submitted a decommissioning plan to complete the radiological decommissioning of the site to obtain termination of the Special Nuclear Materials license issued by the US Nuclear Regulatory Commission (NRC). Remediation of impacted groundwater at the site is the last remaining phase of remediation; this effort is jointly regulated by NRC and DEQ.
Groundwater remediation will consist of extracting impacted groundwater from the Cimarron River floodplain and treating the groundwater to remove uranium (the radiological contaminant) and/or nitrate (the non-radiological contaminant). The treated groundwater will comply with the drinking water standards of 30 micrograms per liter (ug/L) uranium and 10 milligrams per liter (mg/L) nitrate. Our plan is to discharge a portion of the treated water to the Cimarron River in accordance with an Oklahoma Pollution Discharge Elimination System (OPDES) permit.
The rest of the treated water will be injected into the shallow sandstones south of the floodplain to flush contaminants to recovery wells located in the floodplain, where it will be recovered for treatment. In the uppermost sandstone, treated water will be injected via shallow wells installed in injection trenches. Trenches will be excavated and backfilled with gravel to provide adequate hydraulic connection with the fractures and bedding planes within the sandstone. All trenches will be installed in an unconfined water-bearing zone, extending below the existing water table.
In one area, treated water will be injected into a deeper (approximately 70 feet below ground surface) sandstone via injection wells.
Treated water will not be injected under significant pressure to prevent hydraulic fracturing of the receiving bedrock formations. Shut-off switches will be installed in injection wells to cut off flow when the water reaches a point approximately 3 feet below grade, and to restore flow when the water reaches a point approximately 5 feet below grade. Consequently, injection will be gravity flow, with the pressure head being the difference between the potentiometric head in the well and the water table.

environmental properties management, LLC Ms. Hillary Young Oklahoma Department of Environmental Quality May 6, 2016 Page 2 Enclosed are two "Inventory oflnjection Wells" forms, one for each of the quarter sections in which groundwater remediation will be performed. Also enclosed are four drawings from the Decommissioning Plan. Figure 2-1 provides an aerial image of the site, showing the property boundaries. Drawing BMCD-GWREMED-C002 provides an aerial image of most of the site, showing the locations of the groundwater remediation infrastructure.
Injection of treated water will occur within the areas identified on BMCD-GWREMED-C002 as "C004" and "COOS". All of the injection infrastructure located in C004 lies within the northwest quarter of Section 12, T16N, R4W. All the injection infrastructure located in COOS lies within the northeast quarter of Section 12, T 16N, R4 W. The level of detail on this drawing is not sufficient to locate each injection trench and well. Drawings BMCD-GWREMED-C004 and BMCD-GWREMED-C005 are also enclosed to provide a more detailed picture of the groundwater remediation infrastructure in these two areas. For your convenience, I have annotated the locations of injection wells by placing a red dot on each one.
It is our understanding that these injection trenches and wells are Class 5 injection wells, and that no permit is required, as DEQ regulates Class 5 injection wells through "permit by rule". It is also our understanding that DEQ must be provided an inventory of wells and monthly reports of injection during operations. Due to the nature of the inventory, EPM attached a table to the "Inventory of Wells" form that describes the depth and length of each injection trench, as well as the depth, screened interval, and proposed maximum flow rate for each injection well.
DEQ approval to inject treated water during this remediation effort is requested herein. Please contact me at 405-642-5152 or via e-mail at jlux@,envpm.com should you have questions or desire clarification.

Dear Applicant:
Thank you for using the U.S . Fish and Wildlife Service (Service) Oklahoma Ecological Services Field Office online project review process. By providing this letter in conjunction with your project review package, you are certifying that you have accurately completed the online project review process for the referenced project in accordance with all instructions provided, using the best available information to reach your conclusions. Concurrence with "not likely to adversely affect" determinations does not provide any exemption for violations of section 9 of the ESA or "take" of federally-listed species. The Federal action agency is ultimately responsible for ensuring compliance with the ESA and any take that occurs due to your proposed action would be considered a violation under section 9 of the ESA.
This letter and the enclosed project review package complete the review of your project in accordance with the Endangered Species Act of 1973 (16 U.S.C. 1531-1544, 87 Stat. 884), as amended (ESA). This letter also provides information for your project review under the National Environmental Policy Act (National Environmental Policy Act of 1969 (P.L.91-190, 42 U.S.C.
4321-4347, 83 Stat. 852), as amended. A copy of this letter and the project review package must be emailed to okprojectreview@fws.gov for this certification to be valid. This letter and the project review package will be maintained in Service records. Please allow the OKESFO 60 days to review your information. If the OKESFO determines that the package is not complete, or that additional coordination is necessary, we will contact your office. If after 60 days from the time you emailed your project review package the OKESFO has not contacted your office, consider your section 7 consultation complete.
2 The proposed action consists of Burns & McDonnell Engineering Company, Inc. (Burns & McDonnell) is providing environmental support services for the Cimarron Environmental Response Trust (CERT) at a site formerly owned and operated by Kerr-McGee Nuclear Corporation (KMNC) in Logan County, Oklahoma (Project) (Appendix A). For the purpose of informal consultation with the U.S. Fish and Wildlife Service (USFWS), Burns & McDonnell conducted desktop analyses to evaluate threats to species protected by the Endangered Species Act (ESA) (16 U.S.C. 1531 et seq.), Bald and Golden Eagle Protection Act (BGEPA) (16 U.S.C. 668), and the Migratory Bird Treaty Act (MBTA) (16 U.S.C. 703).
Bums & McDonnell and CERT are requesting a concurrence with the findings of this desktop habitat assessment that the proposed Project has no effect or is not likely to adversely affect species protected under the jurisdiction of the USFWS.
The Project is located at a site that was formerly owned and operated by Kerr-McGee Nuclear Corporation. The onsite facilities were utilized for the production of mixed oxide fud and uranium fuel, including enriched uranium reactor fuel pellets and eventually fuel rods from 1966 to 1975. During this time, exposure of process water and material to the environment resulted in the contamination of the site groundwater. The site is now owned by the CERT.
The concentration of uranium, nitrates, and fluorides in the groundwater must be reduced to achieve unrestricted release of the site and license termination from the Nuclear Regulatory Commission (NRC). Additionally, other mitigation and compliance efforts will be completed to obtain a No Further Remediation Required notice from the Oklahoma Department of Environmental Quality (ODEQ). Mitigation of these constituents will be achieved through the extraction, treatment, and discharge of affected groundwater. These processes will require the construction of groundwater extraction wells, groundwater extraction trenches, groundwater injection wells, groundwater injection trenches, process piping, two outfalls to the Cimarron River, and groundwater treatment facilities. All best management practices (BMPs) will be implemented in compliance with associated erosion and sedimentation regulations for disturbance; thereby minimizing those associated impacts.
3 The project is expected to be completed:
July 2018 This project review is needed for:
The concentration of uranium, nitrates, and fluorides in the groundwater must be reduced to achieve unrestricted release of the site and license termination from the NRC. License termination from the NRC, in addition to other mitigation and compliance efforts, is needed for a No Further Remediation Required determination from the ODEQ.
The species conclusions table in the enclosed project review package summarizes your ESA conclusions. These conclusions resulted in "not likely to adversely affect/modify" determinations for listed species and critical habitat in relation to potential effects of your proposed project. We certify that the use of the online project review process in strict accordance with the instructions provided as documented in the enclosed project review package results in reaching the appropriate determinations. Therefore, we concur with determinations of "not likely to adversely affect" for listed species and critical habitat reached by proper use of this process. For projects where this particular determination is reached, additional coordination with this office is not needed.
Candidate species are not legally protected pursuant to the ESA. However, the Service encourages efforts to avoid or minimize adverse impacts to them from project effects. Some federal agencies have standing policies that grant limited protections to candidate species. Conservation of candidate species now may preclude future needs to federally list them as endangered or threatened, at which point their legal protection would become required. Please contact this office for additional coordination if your project action area contains candidate species.
Should project plans change or if additional information on the distribution of listed species or critical habitat becomes available, this determination may be reconsidered. You should re-visit the Service's Information, Planning, and Conservation (IPaC) website at http://ecos/fws.gov/ipac/
within 90 days of project inititaion to ensure species information is correct. If new species or critical habitat is identified, this letter is no longer valid and a new project package should be submitted to the OKESFO.

BURNS ~ M~DONNELL September 8, 2015 Division Chief U.S. Army Corps of Engineers CESWT-RO 1645 South 101 st East Ave Tulsa, OK 74128 Re: Cimarron Remediation Project
Dear Sir/Madam:
Bums & McDonnell Engineering Company, Inc. (Bums & McDonnell) was retained by the Cimarron Environmental Response Trust (Trust) to provide wetland delineation and permitting services for the proposed Cimarron Remediation Project (Project). These actions are part of a larger effort to remediate groundwater contaminated by a former uranium enrichment facility.
INTRODUCTION The Project is located at a site that was formerly owned and operated by Kerr-McGee Nuclear Corporation (KMNC) (Figure A-1 in Appendix A). From 1966 to 1975, the onsite facilities were utilized for the production of mixed oxide fuel and uranium fuel including enriched uranium reactor fuel pellets and eventually fuel rods. During this time, exposure of process water and material to the environment resulted in the contamination of site groundwater. The site is now owned by the Trust. The concentration of uranium, nitrates, and fluorides in the groundwater must be reduced to achieve unrestricted release of the site and license termination from the U.S.
Nuclear Regulatory Commission (NRC) and the Oklahoma Department of Environmental Quality (DEQ). Mitigation of these constituents will be achieved through the extraction, treatment, and discharge of affected groundwater. These processes will require the construction of groundwater extraction wells, groundwater extraction trenches, groundwater injection wells, groundwater injection trenches, process piping, two outfalls to the Cimarron River, and groundwater treatment facilities.
The Project has the potential to impact wetlands or other waters of the U.S. that may be under the jurisdiction of the U.S. Army Corps of Engineers (USACE) as designated by Section 404 of the Clean Water Act. Bums & McDonnell conducted a wetland delineation for the Project to evaluate for the presence of waters of the U.S., including streams, creeks, and ponds. This report has been prepared to identify and assess potential impacts to these waters.
The Project Survey Area included in the wetland delineation (Figures A-2 and A-3) consists of land that may be disturbed during the construction and operation of groundwater remediation activities and totals approximately 600 acres. Some trenching will occur outside of the Survey Area, but will be confined to existing low-maintenance roads in these areas.

BURNS Division Chief September 8, 2015 Page2 METHODS The following sections summarize the methods used to review existing data for the Survey Area and to conduct the onsite wetland delineation.
Desktop Evaluation Bums & McDonnell reviewed available background information for the Survey Area to identify locations where wetlands or streams were likely to be present. This information included:
- U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) Quadrangle:
Crescent, Oklahoma (2002)
- USGS National Hydrography Dataset (NHD) (2014)
- Natural Resources Conservation Service (NRCS) 2012 Soil Survey Geographic (SSURGO) digital data for Logan County, Oklahoma
- Geographic Information System (GIS) User Community aerial images (2015)
- Guidance from the Tulsa office of the USACE regarding the presence/absence of Section 10 Waters.
Wetland presence/absence depicted on the NWI maps was compared with local soil and hydrological data, aerial photography, and topographic maps to assess the most likely locations for wetlands and other waters of the U.S. based on available data. These maps are included as Figures A-2 and A-3.
Wetland Delineation A jurisdictional wetland delineation was conducted on April 23 through 25, 2015, by Jack Finley, senior wetland scientist, and Michael Hogan, Global Positioning System (GPS) specialist, both with Bums & McDonnell. The wetland delineation was conducted in accordance with the 1987 Corps of Engineers Wetlands Delineation Manual (1987 Manual) and Version 2.0 (2010) of the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Great Plains Region (Regional Supplement). Sample plots were established and Wetland Determination Data Forms from the Regional Supplement were completed to characterize the Survey Area (Appendix B). Vegetation, soil conditions, and hydrologic indicators were recorded at each of these sample plots. Locations of the sample plots and water features were recorded using a sub-meter-accurate GPS unit. Natural color photographs of sample plots, wetlands, streams, and uplands were taken onsite and are included as Photographs C-1 through C-21 in Appendix C.
BURNS Division Chief September 8, 2015 Page 3 RESULTS The following sections describe the results of the existing data review and the completed wetland delineation.
Desktop Evaluation Topographic, NWI, and NHD information is shown in Figure A-2. The Survey Area is located in 1
the Cross Timbers Transition Zone of the Central Great Plains Ecoregion. It consists of rough plains that are covered by prairie grasses and eastern red cedar, scattered oaks, and elms. Terrain and vegetation are transitional between the less rugged, grass-covered ecoregions to the west and the hilly oak savanna to the east. Today, land use is a mixture of grassland and fallow ground.
This area has ridge and plain topography, with the ridges generally running north-south and the plains flat or gently sloped. The topography of the Survey Area ranges from an elevation of 1,010 feet on the bluffs overlooking the Cimarron River Floodplain to 930 feet within the floodplain. Topographic contours suggest that numerous drainageways likely to contain ephemeral or intermittent streams emanate from the bluffs into the floodplain.
NHD data indicates that the Project lies within the Lower Cimarron-Skelton Drainage Hydrologic Unit Code (HUC8) 11050002. NWI data indicate the presence of two freshwater ponds and one emergent wetland near the southern edge of the western Survey Area. NHD data shows an intermittent stream flowing through the eastern Survey Area toward the Cimarron River, which is a perennial river, with numerous freshwater wetlands evident throughout the channel.
As shown in Figure A-3, the NRCS SSURGO digital data indicate that the Survey Area includes 12 soil types:
- CoIC2 Coyle-Ironmound complex, 3 to 5 percent slopes, eroded
- DiRG Darsil-Rock outcrop complex, 15 to 45 percent slopes
- GaGA Gaddy-Gracemore complex, 0 to 1 percent slopes, frequently flooded
- GadA Gaddy loamy fine sand, 0 to 1 percent slopes, occasionally flooded
- GooE Goodnight fine sand, 1 to 15 percent slopes
- IrCE Ironmound-Coyle complex, 5 to 15 percent slopes
- LerA Lebron clay, 0 to 1 percent slopes, occasionally flooded
- PIT Pits
- URB Urban land
- YaaA Yahola loam, 0 to 1 percent slopes, occasionally flooded 1

- W Water Of these 12 soil types, 6 (Gaddy-Gracemore complex, 0 to 1 percent slopes, frequently flooded; Gaddy loamy fine sand, 0 to 1 percent slopes, occasionally flooded; Goodnight fine sand, 1 to 15 percent slopes; Lebron clay, 0 to 1 percent slopes, occasionally flooded; Y ahola loam, 0 to 1 percent slopes, occasionally flooded; and the Yahola fine sandy loam, 0 to 1 percent slopes) are included on the local and national hydric soil lists.
Aerial imagery indicates a river system with a forested riparian buffer followed by a broad herbaceous community. This community ends abruptly at another woody community that runs in a southwest to northeast direction. Several prominent wooded drainageways emanate from this community in a southerly direction. Numerous areas of disturbance including roads and excavated areas are present. Several dammed impoundments are adjacent to the Survey Area.
Wetland Delineation On April 22 through 24, 2015, Jack Finley, senior wetland scientist, and Michael Hogan, Global Positioning System (GPS) Specialist, both with Bums & McDonnell, conducted a wetland delineation of the Survey Area. The vegetation, soils, and hydrology within the Survey Area are described below.
Vegetation. The Survey Area was largely composed of grassland. Typical vegetation in the upland portions of the Survey Area included drooping brome (Bromus tectorum ), southern Sedge (Carex austrina), goldenrod (Solidago sp.), common hackberry (Ce/tis occidentalis), and green ash (Fraxinus pennsyvanica).
Soils. Typical upland soils were dark reddish brown (5YR 3/4 or 5YR 4/6) or dark red (2.5YR 4/4 or 2.5YR 3/4) and silt or sand in texture. Wetland soils were also dark reddish brown (5YR 3/4 or 5YR 4/6) and sandy or silty in texture.
Hydrology. The primary sources of hydrology within the Survey Area are precipitation and surface water runoff. Common hydrology indicators included geomorphic position and a positive PAC-Neutral Test.
Jurisdictional Areas One Palustrine Emergent (PEM) wetland, one perennial stream, and two intermittent streams were identified during the wetland delineation (Figure A-4; Photographs C-3 through C-21).
Sample plots were located in the wetlands and adjacent uplands. USACE data forms from the Regional Supplement were completed for each sample plot (Appendix B).
BURNS Division Chief September 8, 2015 Page 5 Wetlands Wetland 1 (W-1) . W-1 (0.28 acre) is a PEM wetland located in the northern portion of the Survey Area (Figure A-4; Photographs C-6, C-7, and C-9). Vegetation in this wetland was dominated by littletooth sedge (Carex microdonta), reed canary grass (Phalaris arundinacea), and stinging nettle (Urtica dioica). The hydrology was indicated by Geomorphic Position (D2) and a positive F AC-Neutral Test (A2).
Streams Stream 1 (S-1) S-1 is a perennial stream (Cimarron River) that flows in an easterly direction at the northern boundary of the Survey Area (Figure A-4; Photographs C-15 and C-16). S-1 averaged more than 400 feet wide, and 988 linear feet of its length were delineated within the Survey Area. S-1 is approximately 6 feet deep at the ordinary high water mark (OHWM).
Surrounding vegetation included sandbar willow (Salix interior) and eastern red cedar (Juniperus virginiana).
Stream 2 (S-2) S-2 is an intermittent stream that flows in a northerly direction through the Survey Area (Figure A-4; Photographs C-17 and C-18). S-2 averaged 3 feet wide, and 326 linear feet of its length were delineated within the Survey Area. S-2 had a depth of 0.5 foot at the OHWM, and the substrate of S-2 consisted of silt and sandstone.
Stream 3 (S-3) S-3 is an intermittent stream that flows in a northerly direction through the Survey Area (Figure A-4; Photographs C-20 and C-21 ). S-3 averaged 3 feet wide, and 1,395 linear feet of its length were delineated within the Survey Area. The substrate of S-3 consisted of silt and sandstone, and the depth at the OHWM was 0.3 foot.
SUMMARY
Burns & McDonnell conducted a wetland delineation of the Survey Area to identify wetlands and other waters of the U.S. One wetland and three stream channels were identified. Although impacts to these waters will be avoided to the extent practicable, the installation of the two outfall structures will create permanent, unavoidable impacts at the Cimarron River (S-1 ).
Additionally, temporary impacts will occur at W-1 due to open trenching during construction of the outfall at that location. As a result, it is anticipated that the Project will require authorization under a Nationwide Permit 7 (NWP 7) for intake and outfall structures, requiring formal notification to the USACE.
Burns & McDonnell on behalf of the Trust would like to respectfully request a preliminary jurisdictional determination of the waters described in this report. Additionally, we would like to request concurrence that the Project, as currently designed, would qualify for authorization under aNWP 7.

BURNS ~ M£DONNELL 02/09/2017 David Ball Logan County Emergency Management 312 East Harrison Guthrie, OK 73044 Re: Floodplain Permit Application for the Environmental Properties Management, LLC Groundwater Remediation Project
Dear Mr. Ball,
Environmental Properties Management LLC (EPM), a Trustee for the Cimarron Environmental Response Trust (CERT), has retained Bums & McDonnell Engineering Company, Inc. (Bums &
McDonnell) to provide FEMA floodplain permitting for the proposed Groundwater Remediation Project (Project). These actions are part of a larger effort to remediate groundwater contaminated by a former nuclear fuel production facility.
The Project is located at a site that was formerly owned and operated by Kerr-McGee Nuclear Corporation (KMNC) in Logan County, Oklahoma. From 1966 to 1975, the onsite facilities were utilized for the production of mixed oxide fuel and uranium fuel including enriched uranium reactor fuel pellets and eventually fuel rods. During this time, exposure of process water and material to the environment resulted in the contamination of site groundwater. The site is now owned by CERT. The concentration of uranium, nitrates, and fluorides in the groundwater must be reduced to achieve unrestricted release of the site and license termination from the U.S.
Nuclear Regulatory Commission (NRC) and the Oklahoma Department of Environmental Quality (DEQ). Mitigation of these constituents will be achieved through the extraction, treatment, and discharge of affected groundwater.
This phase of the Project will construct four water injection trenches and one groundwater extraction trench, followed by testing of injection and extraction efficiencies as part of final design for the Project. Two of the test trenches will be within the FEMA 100-year floodplain.
These test trenches will be excavated to the specified dimensions. The injection wells will be constructed in the trenches and the then the trench will be partially backfilled with aggregate.
The trenches will then be returned to their previous contours using the excavated spoils and stabilized.
The groundwater injection and extraction efficiency will be tested by placing a frac tank, utilized to supply clean water, near the targeted injection trench and moved as necessary. Following completion of injection testing activities, this frac tank will be removed from the Project site.
Two frac tanks will be utilized to store water generated during the extraction trench tests. These frac tanks will remain onsite pending characterization and treatment (as necessary) of the extracted water. These tanks will be staged outside of the FEMA 100-year floodplain to avoid any potential impacts, to the extent practicable, should flooding occur.

APPENDIX J - SPILL REPORT FORM Procedures for Determining if a Hazardous Material Spill is a Reportable Quantity
- 1) First determine the type and quantity of material that has been spilled.
- 2) Obtain a safety data sheet (SDS) for the spilled material and determine whether any of the constituents are listed in Table 302.4 in 40 CFR 302.
- 3) If none of the constituents in the spilled material are listed in the table (excluding ethylene glycol), the spill is not reportable.
- 4) If the constituents in the spilled material are listed in the table, use the following equation to determine the pounds of material spilled:
Pounds Spilled = (V) (Wt3/4) (Sg) (0.0834)
Where:
V = Volume of the material spilled, in gallons Wt3/4 = The weight percent of the constituents in the spilled material (see the SDS)
Sg = Specific gravity of spilled material (see SDS)
For Example:
V = 7 gallons Wt3/4 = 3.5 Sg = 1.04 Pounds Spilled = (7) (3.5) (1.04) (0.0834) = 2.13 pounds
- 5) If, based on the calculation, the pounds spilled are greater than the Final RQ (reportable quantity) value listed in Table 302.4 of 40 CFR 302 or the State's reportable quantity minimum amount, the spill must be reported to the appropriate Federal, State, and local agencies.
