July 25, 2024 Division Chief U.S. Army Corps of Engineers, Tulsa District CESWT-RO 1645 South 101st East Ave Tulsa, OK 74128 Re: Cimarron Remediation Project
Dear Sir/Madam:
Burns & McDonnell Engineering Company, Inc. (Burns & 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 fuel production facility. Background on the proposed Project and methodology and results of the wetland delineation are described below.
INTRODUCTION The Project is located at a site that was initially owned and operated by Kerr-McGee Nuclear Corporation (KMNC). 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 in the groundwater must be reduced to achieve license termination from t he U.S.
Nuclear Regulatory Commission (NRC).
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. Burns & McDonnell conducted a wetland delineation for the Project to evaluate the presence of wetlands and other waterbodies, including streams, drainages, and ponds. The wetland delineation was conducted based on the maximum area of potential disturbance (Survey Area) provided by the Trust.
The Survey Area included in the wetland delineation (Figure A-4, Appendix A) consists of land that may be disturbed during the construction and operation of groundwater remediation activities and totals approximately 40.75 acres. A lso included in the Survey Area is an area approximately 5.27 acres in size located on the 9400 Ward Parkway \\ Kansas City, MO 64114 0 816-333-9400 \\ burnsmcd.com

eastern side of the Project area. While this area will not be disturbed during construction, it was included in the wetland delineation to provide additional information to the NRC. The total Survey Area, including the proposed construction and undisturbed area is approximately 46 acres.
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 Burns & 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. Geological Survey (USGS) 7:24,000 Topographic Quadrangle: Crescent, Oklahoma (2024)
U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI)
Quadrangle: Crescent, Oklahoma (2024)
USGS National Hydrography Dataset (NHD) (2024)
Natural Resources Conservation Service (NRCS) 2023 Soil Survey Geographic (SSURGO) digital data for Logan County, Oklahoma Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) (2024)
National Agriculture Imagery Program (NAIP) aerial photography (2019)
Wetland presence based only on NWI maps or other background data cannot be assumed to be a wholly accurate assessment of potentially occurring jurisdictional wetlands. Wetland identification criteria differ between the USFWS and the USACE.
As a result, wetlands shown on an NWI map may not be under the jurisdiction of the USACE, and all USACE-jurisdictional wetlands may not be included on NWI maps.
Therefore, a field visit was conducted to identify any wetlands or other waterbodies within the Survey Area.
Wetland Delineation A Burns & McDonnell wetland scientist completed an onsite wetland delineation from May 7 through 8, 2024. The delineation was completed in accordance with the 1987 Corps of Engineers Wetlands Delineation Manual (1987 Manual) and the 2010
Division Chief July 25, 2024 Page 3 BURNS t,.M£DONNELL.
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region - Version 2.0 (Regional Supplement). Sample plots were established at multiple locations 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 sample plot. Locations of sample plots and other identified features were recorded using a sub-meter accurate global positioning system (GPS) unit. Natural color photographs were taken onsite and are included in Appendix C (Photographs C-1 through C-16).
RESULTS The following sections describe the results of the existing data review and the completed wetland delineation.
Desktop Evaluation The existing USGS topographic maps were reviewed to familiarize Burns &
McDonnell wetland personnel with the topography of the Survey Area and potential locations of wetlands and other waterbodies (Figure A-2). NHD data indicates that the Cimarron River and two unnamed drainages are present in the Survey Area.
NHD data also indicates that the Project lies within the Lower Cimarron-Skelton Drainage Hydrologic Unit Code (HUC8) 11050002. NWI data indicates the presence of one freshwater pond and one freshwater lake along the southern edge of the western Survey Area.
As shown in Figure A-3, the NRCS SSURGO digital data indicates that the Survey Area includes 13 soil types. Of the 13 soil types, three soils are included on the local and national hydric soil lists: GaGA - Gaddy-Gracemore complex, GadA - Gaddy loamy fine sand, and LerA - Lebron clay.
The USACE Antecedent Precipitation Tool (APT) indicates that the area surrounding the Project experienced normal conditions on May 7 through 8, 2024, (Appendix D).
Wetland Delineation On May 7 through 8, 2024, Aaron Conley, a staff wetland scientist, and Julie McDonald, a Global Positioning System (GPS) Specialist, both with Burns &
McDonnell, conducted a wetland delineation of the Survey Area. The vegetation, soils, and hydrology within the Survey Area are described below.
Division Chief July 25, 2024 Page 4 BURNS t,.M£DONNELL.
Vegetation. The Survey Area was largely composed of grassland, but it also contained sparce scrub-shrub along existing access roads and mature hardwood forest adjacent to the riparian areas of the Survey Area. Typical vegetation in the upland portions of the Survey Area included drooping brome (Bromus tectorum),
Canada goldenrod (Solidago canadensis), common yarrow (Achillea millefolium),
coralberry (Symphoricarpos orbicu/atus), chickasaw plum (Prunus angustifo/ia),
Eastern red-cedar (Juniperus virginiana), five-stamen tamarisk (Tamarix chinensis),
smooth sumac (Rhus g/abra), wing-leaf soapberry (Sapindus Saponaria), Kentucky coffeetree (Gymnoc/adus dioicus), bur oak (Quercus macrocarpa), common hackberry (Ce/tis occidentalis), and green ash (Fraxinus pennsyvanica).
Soils. Typical upland soils were red (2.5YR 5/6 or 2.5YR 5/8), dark reddish brown (2.5 YR 3/4, 5YR 3/4, or 5YR 4/6), and clayey or loamy in texture. Wetland soils were also dark reddish brown (5YR 3/3 or 5YR 4/3) or red (2.5 YR 5/8) and were clayey or loamy in texture with a thin muck surface.
Hydrology. Indicators of hydrology within the wetlands included surface water, high water table, saturated soil, inundation visible on aerial imagery, water-stained leaves, thin muck surface, drainage patterns, saturation visible on aerial imagery, geomorphic position, and a positive FAC neutral test.
Delineated Features Two Palustrine Emergent (PEM) wetlands, two open water pond (PUB) wetlands, two perennial streams, four intermittent streams, and three ephemeral streams were identified during the wetland delineation (Figure A-4; Photographs C-1 through C-16).
Sample plots were located in the PEM wetlands and adjacent uplands. USACE data forms from the Regional Supplement were completed for each sample plot (Appendix B).
Wetlands Table 1 provides the type and size of each PEM and PUB wetlands delineated within the Survey Area. Each type is described in more detail below.
Division Chief July 25, 2024 Page 5 BURNS&1£DONNELL.
Table 1: Type and Size of Wetlands and Open Water Ponds Delineated Area of Wetland Delineated in Wetland Wetland Survey Area Figure 4 Page Number Type (acre)
Number W-01 PEM 0.84 Page 1 W-02 PEM 0.05 Page 1 WB-01 PUB 0.17 Page 1 WB-02 PUB 0.06 Pagel,2 Wetland 1 (W-01) is a PEM wetland approximately 0.84 acres in size located in the eastern portion of the Survey Area (Figure A-4; Photographs C-1 and C-2).
Vegetation in this wetland was dominated by blunt spike-rush (Eleocharis obtusa).
The hydrology was indicated by surface water, high water table, saturation, inundation visible on aerial imagery, drainage patterns, saturation visible on aerial imagery, geomorphic position, and FAC-Neutral test. No hydric soil indicators were met at the time of the field survey, however due to the rapid test for hydrophytic vegetation and primary hydrology indicators, this feature was determined to be a wetland.
Wetland 2 (W-02) is a PEM wetland approximately 0.05 acres in size located in the eastern portion of the Survey Area (Figure A-4; Photographs C-3 and C-4).
Vegetation in this wetland was dominated by rice cutgrass (Leersia oryzoides) and broad-leaf cattail (Typha !atifolia). The hydrology was indicated by surface water, high water table, saturation, water-stained leaves, thin muck surface, geomorphic position, and FAC-Neutral test.
Open Water Pond 01 (WB-01) is a PUB wetland approximately 0.17 acres in size located in the eastern portion of the Survey Area (Figure A-4; Photograph C-14).
WB-01 was located directly adjacent to W-01.
Open Water Pond 02 (WB-02) is a PUB wetland approximately 0.06 acres in size located in the eastern portion of the Survey Area (Figure A-4; Photographs C-15 and

S-03 averaged 3 feet wide at the OHWM, and 282 linear feet of its length were delineated within the Survey Area. S-03 had a depth of 0.25 feet at the OHWM and contained silt and clay substrates.
Stream S-04 is an intermittent stream that flowed northwest through the Survey Area (Figure A-4; Photograph C-8). S-04 averaged 6 feet wide at the OHWM, and 730 linear feet of its length were delineated within the Survey Area. S-04 had a depth of 0.5 feet at the OHWM and contained silt, gravel, and cobble substrates.
Stream S-05 is an intermittent stream that flowed north through the Survey Area (Figure A-4; Photograph C-9). S-05 averaged 10 feet wide at the OHWM, and 47 linear feet of its length were delineated within the Survey Area. S-05 had a depth of 0.5 feet at the OHWM and contained silt and clay substrates.
Stream S-06 is an intermittent stream that flowed north through the Survey Area (Figure A-4; Photograph C-70). S-06 averaged 70 feet wide at the OHWM, and 469 linear feet of its length was delineated within the Survey Area. S-06 had a depth of 0.5 feet at the OHWM and contained silt and clay substrates. The majority of this channel contained beaver impoundments leading to a flooded area that averaged approximately 10 feet wide.
Stream S-07 is an intermittent stream that flowed north through the Survey Area (Figure A-4; Photograph C-11). S-07 averaged 4 feet wide at the OHWM, and 115 linear feet of its length were delineated within the Survey Area. S-07 had a depth of 0.5 feet at the OHWM and contained silt and clay substrates.
Stream S-08 is an ephemeral stream that flowed northeast through t he Survey Area (Figure A-4; Photograph C-12). S-08 averaged 3 feet wide at the OHWM, and 275 linear feet of its length were delineated within the Survey Area. S-08 had a depth of 0.1 feet at the OHWM and contained silt and clay substrates.
Stream S-09 is a perennial stream that flowed northwest through the Survey Area (Figure A-4; Photograph C-73). S-09 averaged 12 feet wide at the OHWM, and 151
Division Chief July 25, 2024 Page 8 BURNs&1soONNELL linear feet of its length were delineated within the Survey Area. S-08 had a depth of 1 foot at the OHWM, and contained silt, clay, gravel, and cobble substrates.
SUMMARY
Burns & McDonnell conducted a wetland delineation of the Survey Area to identify wetlands and other water resources. A total of four wetlands and nine streams were identified during the delineation efforts.
If impacts to waters of the U.S. cannot be completely avoided, they should be minimized, and a Section 404 permit from the USACE would be required. Once the final Project design is known, an assessment of potential impacts, if applicable, and a permitting strategy can be determined.

Wetland sample plot in PEM W-01. The USACE Antecedent Precipitation Tool indicates normal conditions were present 3 months prior to survey. Due to the predominance of hydrophytic vegetation and the presence of wetland hydrology indicators, this area is identified as wetland through professional opinion. Soils and hydrology in this area were disturbed due to the spillway of the adjacent pond (WB-01) breaching and causing addition down valley inundation and erosion. Sediment runoff from the spillway levee has collected and settled in this area.
