Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 1 1.0 Introduction This report presents the results of a preliminary jurisdictional determination of waters of the United States (wetlands and streams) for the Callaway Nuclear Plant Unit 2 COLA project. The study area is located primarily in Callaway County, Missouri, but also extends south of the

Missouri River into Osage County as shown in Figure 1-1.

The purpose of this report is to support Clean Water Act (CWA) Sections 404 and 401 permit applications as defined by 33 Code of Federal Regulations (CFR) Part 323. The U.S. Army Corps of Engineers (USACE) reviews project plans and issues Section 404 permits for dredge and fill activities within waters of the United States. Section 401 of the CWA requires that water quality certifications be obtained for any activity that results in impacts to jurisdictional streams or jurisdictional wetlands. This program is overseen in Missouri by the Missouri Department of Natural Resources (MDNR).

Specific objectives of this report include the identification and delineation of jurisdictional waters of the United States near the Callaway Nuclear Plant. This information is intended as a tool to assist the USACE in reviewing the proposed Callaway Unit 2 COLA project. Impacts as a result of the proposed project cannot be quantified in this report due to a lack of detailed design at this stage of the project. Impacts will be quantified in detail at a later time as detailed design information becomes available.

Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 2 2.0 Methodology Wetlands and streams occurring within the study area were identified utilizing a variety of existing data sources, which includes: Natural Resources Conservation Service (NRCS) soil maps (Figure 2-1); National Wetland Inventory (NWI) maps (Figure 2-2); U.S. Geological Survey (USGS) topographic mapping (Figure 2-3); Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) (Figure 2-4). NRCS Food Security Act wetland mapping (Figure 2-5); and Aerial photography (2006).

Wetlands were initially identified using NWI and NRCS maps. Streams were identified on USGS topographic maps. Subsequent field work was conducted to confirm mapped resources, identify additional resources, and provide for more accurate mapping of those resources.

2.1 Wetlands Wetlands are defined as those areas that are "inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas" [33 CFR 328.3(b)].

Wetlands within the project area were identified and delineated in accordance with the USACE 1987 Wetland Delineation Manual (USACE, 1987). Wetland delineation was performed in 2007 and early 2008 prior to the USACE Kansas City District October 23, 2008 Public Notice announcing the publication and one year trial implementation period for the Midwest Interim Regional Supplement to the 1987 Wetland Delineation Manual. As such, the Routine On-Site Investigation Approach of the 1987 Wetland Delineation Manual was utilized to determine if an area met the wetland criteria. Methodology consisted of establishing wetland determination plots which documented the vegetation, soils, and hydrology at each plot location. Potential wetland areas are considered wetlands if they meet all three of the following wetland criteria:

1. Hydrophytic Vegetation - Hydrophytic vegetation is present when the prevalent vegetation consists of species that are typically adapted to prolonged inundation or soil saturation during the growing season. This criterion may not need to be met if the area has been disturbed (farmed, etc.) and the natural vegetation has been removed.

2. Hydric Soil - Hydric soils are formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part.

3. Hydrology - Wetland hydrology may include inundation either permanently or periodically or soil saturation to the surface at some time during the growing season. In order for a wetland to be considered a jurisdictional water of the United States, the 2001 Supreme Court decision in Solid Waste Agency of Northern Cook County (SWANCC) versus USACE requires that a wetland be hydrologically connected to a jurisdictional water of the United States. Further guidance has been given subsequent to the 2006 Supreme Court Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 3 decision in Rapanos v. United States. In accordance with the Rapanos decision, the USACE and USEPA will assert jurisdiction over: Traditionally navigable waters (TNW) and wetlands adjacent to TNWs; Waters that are not TNWs provided they are relatively permanent waters - i.e. waters flow year-round, or at least "seasonally," (typically three months) and includes wetlands adjacent to such water bodies if the wetlands "directly abut" the water body; and Waters that are neither TNWs nor relatively permanent waters provided that a "significant nexus" exists between the water (including adjacent wetlands) and a TNW. The USACE and USEPA will generally not assert jurisdiction over swales, erosional features, or ditches (including roadside ditches) excavated wholly in and draining only uplands and that do not carry a relatively permanent flow of water.

Wetlands were classified according to the hierarchical system developed by the U.S. Fish and Wildlife Service (USFWS) (1979). Wetlands were delineated using a global positioning system (GPS) which was subsequently downloaded into ArcView geographical information system (GIS). The GIS information was used to generate the report figures and ultimately will be used to quantify project-related impacts.

The classification system used for wetland delineations is presented below.

Palustrine Wetlands According to the classification system of the USFWS (1979), palustrine wetlands cover less than 8.1 hectares (20 acres), lack active wave-formed or bedrock shoreline features, and have water depths at low water of less than 1.8 meters (6 feet). Palustrine wetlands are subsequently classified according to dominant vegetation: Palustrine Unconsolidated Bottom (PUB) wetlands are characterized by a substrate composed of particles smaller than stone and a vegetative cover less than 30 percent. This classification is typically applied to small "pond-like" wetlands. Palustrine Emergent (PEM) wetlands are characterized by a dominance of herbaceous (non-woody) plants. Emergent wetlands are also known as marshes, meadows, fens, etc. Palustrine Scrub-Shrub (PSS) wetlands are characterized by a predominance of woody vegetation that is less than 6 m (19.6 ft) tall. Palustrine Forested (PFO) wetlands are characterized by a predominance of woody vegetation that is 6 m (19.6 ft) tall or taller.

Some palustrine wetlands are modified by agricultural practices. The NRCS has previously had jurisdiction over the mapping of some farmed wetlands, which consist of active row crop or pasture. These areas meet the wetland soils and hydrology criteria but are currently used for agriculture. The NRCS has several classifications within this group [prior converted cropland (PC), farmed wetland (FW), wetland pasture (WP), etc.]. Because of soil saturation, farmed wetlands typically are not able to produce crops every year. Farmed wetlands typically have lower plant diversity and reduced functional values compared to other wetland types. Prior converted cropland is agricultural land that was manipulated and drained before December 1985 and is no longer considered a wetland area.

Riverine Wetlands Riverine wetlands include all wetlands and deep water habitats contained within a channel that are not dominated by trees, shrubs, or emergent vegetation (USFWS, 1979). The USFWS riverine classification is typically used to describe perennial or intermittent streams/rivers and Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 4 active (at least seasonally) side channels. These streams may be considered "waters of the United States." Logan Creek is classified by NWI as a riverine wetland, perennial stream, and is located within the study area.

2.2 Streams The field determination of streams as jurisdictional resources was based upon the presence of an ordinary high water mark (OHWM), observable "bed and bank," and the presence of documented surface water connections to navigable waters of the United States.

According to 33 CFR 328.3, "the term ordinary high water mark" means "the line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas." In general, the OHWM for a stream is usually determined through an examination of the recent physical evidence of surface flow in the stream channel. Watercourses that contain an observable bed and bank, and exhibit an OHWM, are classified as waters of the United States and are regulated by the USACE under Section 404 of the CWA and by MDNR under Section 401. Coordination with the USACE and MDNR is necessary for all identified waters of the United States. The aerial photograph, topographic maps, and GPS were used to delineate jurisdictional streams. This information was imported into GIS for subsequent identification and ultimate quantification of stream crossings.

2.3 Floodplains Floodplains of the project area were identified by incorporation of designated 100-year floodplain limits (Zone A) from the FEMA floodplain information provided by the University of Missouri, Columbia (Figure 2-4). Floodplain limits were downloaded and incorporated into the project GIS. Potential floodplain encroachment and related impacts to the natural and beneficial values of floodplains are being evaluated pursuant to Executive Order 11988 regarding Floodplain Management. 2.4 Agency Coordination The NRCS was contacted to determine if farmed wetlands had been mapped within the Missouri River floodplain portion of the study area. A Resource Conservationist in the Fulton, Missouri office of the NRCS provided maps of the study area (Figure 2-5). The results of NRCS wetland mapping are discussed further in Section 4.0 of this report. 2.5 Wetland Functional Assessment Various techniques have been used for assessing wetland functions: Wetland Evaluation Technique (WET) (Adamus, 1983) and the Hydrogeomorphic Method (HGM) approach (USACE, 1995a and 1995b). Currently there is no standard or required approach for performing functional assessments in the USACE Kansas City District. The HGM assessment requires detailed site-specific information that is compared to a regional reference wetland (USACE, 1995a). Currently there are no regional reference wetlands for comparison within the USACE Kansas City District. Several functional assessment parameters (e.g., nutrient cycling, organic carbon export, etc.) cannot be determined without long-term monitoring and detailed site-specific information that is not available. Other parameters (water storage, wildlife habitat, etc.) may be evaluated in Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 5 qualitative terms. As an example, a wetland located in a floodplain with the presence of watermarks on trees and sediment deposits may be inferred as having high surface water storage and water quality improvement functions. Similarly, a wetland with a variety of community types (i.e., open water, emergent, and forested wetlands), and high plant diversity may be inferred as having a high wildlife functional value. Given the level of site-specific information needed to perform a quantitative functional assessment, a practical wetland assessment for the study area focuses on key functions that can be rated qualitatively (e.g., low, medium, high). The functional value of each wetland has been assessed in the context of a broader landscape perspective. On the landscape level the functional value is dependent on size, position, and quality. As an example, a wetland which is defined as having high hydrologic functions is based on a qualitative comparison of the size, position, and quality of the wetland to other wetlands in the associated landscape. Functions typically performed by these wetlands include the following: Flood abatement. The capacity and effectiveness of wetlands to provide value in flood abatement is often related to its landscape position and potential for storing stormwater that is conveyed by runoff or by adjacent stream flooding. Several wetlands are located variously within the landscape along streams (intermittent tributaries and perennial streams) and to varying degrees perform this function. Wetlands located on floodplains of larger rivers such as the Missouri River generally have higher functional value than those located along smaller unnamed intermittent streams, provided the wetland's topographic position allows for a relatively frequent connection between the wetland and stream. Sediment retention

. As is the case with flood abatement, the capacity of a wetland to trap and detain sediments is often related to such factors as erodibility of the surrounding landscape, velocity of water moving through the wetland, nature and extent of vegetation within the wetland, and the availability of a topographic "sink" that can effectively contain sediments that are deposited by in-coming flow. In consideration of these factors, wetlands in the study area are variable with respect to their effectiveness in retaining sediments. Open water systems (farm ponds, impoundments) perform this function most effectively as they contain a natural topographic sink, and are typically located within disturbed, highly erodible landscapes. Nutrient retention and removal

. This function reflects the capacity of wetlands to retain nutrients carried by sheet or channel flow and retain and remove those nutrients within the wetland. Nutrients may either be deposited within "sinks", bound up by absorbtion/adsorbtion with soils or may be incorporated as part of the biomass of wetland vegetation. Water quality enhancement. The capacity for wetlands to perform water quality enhancement is linked to their vegetative characteristics, residence time of the water passing through the wetland (hydroperiod), and geochemical composition of the substrates. Wildlife habitat

. Wetlands often give abundant support to wildlife by providing foraging habitat, nesting habitat, escape cover, and corridors for movement and dispersal. Structural complexity of the plant communities of the wetland area are often directly linked to the relative value of this wetland function. Aquatic ecosystem support

. Wetlands provide value in supporting aquatic ecosystems by serving as persistent aquatic environments that support fish and aquatic invertebrates, and by providing temporary aquatic habitats during periods of flooding. Open water habitats generally act as perennial aquatic habitats and may be expected to support full life cycles of aquatic biota. In contrast, wetlands with temporary or seasonal Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 6 hydroperiods may only be expected to provide intermittent support to aquatic biota. Specific benefits of such wetlands to the aquatic environment include foraging habitat for aquatic biota, and temporary breeding areas for semi-aquatic species (frogs and toads) that may use fishless depressional habitats for breeding and life stage maturation.

The study area is further divided into two ecological subsections and three land type associations (LTA) (Nigh and Schroeder, 2002) which consist of north to south: OZ12 Outer Ozark Border Subsection OZ12m - Central Missouri Savanna/Woodland Dissected Plain OZ12h - Central Missouri Oak Woodland/Forest Hills OZ15 Missouri River Alluvial Plain Subsection OZ15a - Lower Missouri River Alluvial Plain Descriptions of the LTAs (north to south) as presented by Nigh and Schroeder are as follows:

OZ12m Central Missouri Savanna/Woodland Dissected Plain is a transition between the Ozarks and the till plain. Many of the uplands are flat and have glacial till, which appear as fingerlike extensions of the till plain projecting toward the Missouri River. The valleys are reasonably deep and represent Ozark-like landscapes projecting northward from the Missouri River. Local relief averages 150 to 200 feet. Soils vary from claypans and silty clays on the loess-covered divides to cherty loams in the valleys. Historically, the LTA was oak savanna and woodland in the valleys and mostly prairies on the flat ridges. Today, the LTA is mainly fescue pasture with scattered cropland and dense old-field thickets and second-growth timber on steeper slopes.

Development pressures are occurring at Fulton and along the major highways. Missouri's only commercial nuclear power plant is on a flat upland in southeastern Callaway County.

OZ12h Central Missouri Oak Woodland/Forest Hills consists of deeply dissected hills and bluffs with local relief ranging from 150 feet away from the Missouri River to more than 250 feet close to it. Bluffs along the Missouri River and entrenched tributaries have bold rock cliffs. Loess is thick near the bluffs and thins away from them. Narrow loess-covered ridges give way to steep slopes and narrow valleys in the Mississippian and Devonian limestone, and Ordovician Jefferson City-Cotter dolomite. Cedar and Auxvasse creeks form the largest valleys. Soils range from deep silt loams in loess, through cherty silt loams from limestone, to shallow soils over bedrock. Historically, oak woodland graded into oak and mixed-hardwood forests in the valleys. Frequent limestone and dolomite glades and woodlands occurred on exposed slopes.

Today, some of the ridges and bottoms are cleared pasture with limited cropland or dense cedar-hardwood old field thickets. Steeper lands are largely timbered in second-growth forest with numerous overgrown limestone or dolomite glades. Streams contain federally listed Topeka shiners and other rare fish species. Some outstanding glades occur. Several unique areas are associated with isolated outcrops of St. Peter sandstone. Public lands include some national forest land and state conservation land.

OZ15a Lower Missouri River Alluvial Plain consists of a river channel half of its former width and of a relatively narrow alluvial plain restricted by bluffs cut into Ozark bedrock materials, primarily dolomites and limestones. Bluff faces have been sharpened by quarrying and by railroad construction at their base. Considerable loess and other sediments have been washed down from the blufflands onto the alluvial plain. Soils are dominated by loamy, well-drained alluvium that was historically timbered. Today, this region is over 95 percent in row crops and levee-protected to varying heights.

Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 8 Soils The NRCS Web Soil Survey (NRCS, 2008) mapped 41 different soils within or near the study area (Table 3-1). Some of the mapped soils within the study area contain hydric inclusions.

These soils are intermediate in that they are not hydric soils throughout the mapped soil unit. For example, Waldron silty clay (Map ID 66111) is a deep, nearly level, somewhat poorly drained soil found in the lower areas on the floodplains along the Missouri River. This mapped soil type has inclusions of hydric soils (Booker) that make up about 5 to 10 percent of the unit.

Five study area soils are mapped as hydric by the NRCS. Mapped hydric soils on the Missouri River floodplain in Callaway County include the Hodge fine sand (Map ID 66034) and Booker silty clay (Map ID 13598) soils. Hodge fine sand is a deep, nearly level, somewhat excessively drained soil that is frequently flooded. This soil has inclusions of small areas of the well drained Grable soils on broad natural levees and the somewhat poorly drained Leta soils on low ridges. The greatest concentration of Hodge soils in the study area is mapped along the Missouri River and Mollie Dozier Chute on Binggeli Island.

Booker silty clay (Map ID 13598) is a deep, nearly level, very poorly drained soil found along low drainageways and in broad depressional areas scattered throughout the Missouri River floodplain in Callaway County. This soil is subject to flooding and ponding and has small areas of Dupo, Leta, and Waldron soils that make up less than 5 percent of the unit. Permeability is very slow in Booker soils.

Hydric soils mapped on the Missouri River floodplain in Osage County include Sarpy fine sand (Map ID 66010) and Blake silt loam (Map ID 66012). Sarpy fine sand consists of sandy alluvium and is excessively drained but frequently flooded. Blake silt loam consists of fine silty alluvium, is somewhat poorly drained, and is frequently flooded but not ponded. In Osage County, the proposed transmission line corridor will traverse an area mapped as Sarpy fine sand.

Moniteau silt loam (Map ID 66000) is the only hydric soil mapped in the upland area near the plant. This soil is located in linear drainages north of the plant and consists of fine silty alluvium. Moniteau is poorly drained, occasionally flooded, but not ponded.

Non-hydric upland soils present within the study area include Cedargap loam, Gorin silt loam, Goss-Gasconade-Rock outcrop complex, Grable very fine sandy loam, and Leta silty clay loam. These soils also contain inclusions. For example, Grable very fine sandy loam is a deep, nearly level, well drained soil that contains inclusions. These inclusions include the somewhat excessively drained Hodge soils in long, narrow areas adjacent to the river and the somewhat poorly drained Leta soils on low ridges. Hodge soils have more sand than Grable soils, and Leta soils have more clay. Included soils, or soils of another map unit, make up 5 to 10 percent of the Grable very fine sandy loam unit.

The NRCS soil survey information was used to compare field observations of soils in potential wetland areas. This information is provided in the wetland data forms included in this report (Appendix A).

Supporting documentation is presented in the form of wetland determination data forms (Appendix A), stream description data forms (Appendix B), and a photographic log (Appendix C). The wetlands were labeled using a unique identifier based on the sheet grid in which it was identified such as "B3-WT-01" where "B3" represents the sheet or grid number used in Figure 4-1, "WT" refers to wetland, and "01" is the sequential wetland number within that sheet or grid. Streams were labeled in the same fashion using "SC" for potential stream crossing. 4.1 Wetlands and Ponds Isolated PUB Wetlands The vast majority of wetlands immediately surrounding the Callaway Plant are shallow (3 to 5-feet deep), isolated ponds constructed in fields currently or formerly used as pasture. Fifteen such ponds were delineated within the study area and have been classified as palustrine unconsolidated bottom (PUB) ponds. These ponds range in size from 0.06 acres to 1.44 acres and generally have a narrow vegetated fringe of hydrophytic vegetation consisting of sedges (Carex spp.), rice cut grass (Leersia oryzoides), smartweeds (Polygonum spp.), and/or willows (Salix spp.). Because the ponds are isolated from the traditional navigable waters of the Missouri River, they are preliminarily identified as non-jurisdictional resources. The following isolated PUBs can be identified on Figure 4-1 with associated data sheets and photos included in Appendix A and C, respectively. Additional information, including a qualitative functional assessment, can be found in Table 4-1.

B3-WT-03 is the only farm pond constructed in an upland area near the plant that is considered jurisdictional. This pond is small (0.10 acres) and is similar in habitat to the isolated ponds listed above. Because it is located adjacent to stream C3-SC-02, an unnamed intermittent tributary which flows north to Cow Creek, a tributary of Auxvasse Creek which is tributary to the Missouri River, B3-WT-03 is preliminarily identified as a jurisdictional water of the United States.

Wetlands I8-WT-05, I8-WT-06, I8-WT-07, and J4-WT-01 are all small ponds or scour holes immediately adjacent to the Missouri River and as such are preliminarily identified as jurisdictional waters of the U.S. Appendix C photos 82, 83, 84, 93 and 94 provide images of these PUBs which range in size from 0.16 acres to 1.03 acres. Vegetation commonly found surrounding the ponds include black willows (Salix nigra), sandbar willows (Salix interior), silver maple (Acer saccharinum), and cottonwood (Populus deltoides). Buttonbush (Cephalanthus occidentalis) was a dominant shrub at J4-WT-01.

Wetlands H6-WT-02 and J3-WT-02 are larger scour holes apparently created by the large flood events of 1993 or 1995. H6-WT-02 (Appendix C, Photos 56, 57, and 58) is approximately 13.73 acres and depending on water levels it consists predominantly of PUB (8.46 acres) but with a large PEM area (4.51 acres) and some PFO (0.76 acres) on its south end. Hydrophytic species include black willow, sandbar willow, cottonwood, and dark green rush (Scirpus atrovirens). J3-WT-02 (Appendix C, Photos 87, 88, and 89) is approximately 6.06 acres consisting almost entirely of open water but with a narrow vegetated fringe around its perimeter. Hydrophytic species include black willow, silver maple, cottonwood, and water heartsease

(Polygonum coccineum

).

The following jurisdictional PUBs can be identified on Figure 4-1. Associated data sheets and photos are included in Appendix A and C, respectively. Additional information, including a qualitative functional assessment, can be found in Table 4-1.

Years of sediment deposition leaves the chute dry throughout much of the year but high water flows on the Missouri River in late winter and spring typically connect the chute to the river, thus the chute is considered a jurisdictional water of the U.S. Typical herbaceous species include sedges, smartweeds, beggar's ticks (Bidens spp.), and barnyard grass (Echinochloa crusgalli). Dominant woody species include black willow, sandbar willow, peach-leaved willow (Salix amygdaloides), cottonwood, sliver maple, and sycamore (Platanus occidentalis). These three Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 13 wetland areas connect together to form one water of the United States within the levees but the areas in between were not field delineated.

Wetlands D4-WT-03, D5-WT-01, D5-WT-02, and D5-WT-03 are small isolated emergent wetlands without any connection to the traditionally navigable waters of the Missouri River. Ranging in size from 0.03 acres to 0.18 acres, these wetlands are dominated by narrow-leaved cattails (Typha angustifolia), reed canary grass (Phalaris arundinacea), rice cut grass, and sedges. D4-WT-03 is the smallest of the four non-jurisdictional PEMs but is the most diverse botanically and consists of an old dried up farm pond (see the data sheet in Appendix A and the photo in Appendix C, Photo 30).

The following non-jurisdictional emergent wetlands can be identified on Figure 4-1. Associated data sheets and photos are included in Appendix A and C, respectively. Additional information, including a qualitative functional assessment, can be found in Table 4-1.

C4-WT-01 is the only jurisdictional PEM wetland in the upland area surrounding the Callaway Plant. This wetland is 0.43 acres in size and is dominated by narrow-leaved cattail, sedges, dark green rush, barnyard grass, and also includes some black willow and buttonbush. C4-WT-01 flows into P-5 which is drained by an unnamed stream (B4-SC-01) which flows through Canyon Lake to the north before discharging to Cow Creek, a tributary of Auxvasse Creek, which is tributary to the traditionally navigable waters of the Missouri River.

Wetland H5-WT-02 (Appendix C, Photo 48) is a 3.51-acre wetland that is predominantly PEM but also includes some portions of PFO (1.20 acres) and PSS (0.88 acres). This wetland is located adjacent to and north of the KATY Trail and is connected via a ditch line to Logan Creek, a perennial tributary of the Missouri River. Common hydrophytic species include sedges, Virginia wild rye (Elymus virginicus), silver maple, willows, and buttonbush.

Wetland H6-WT-01 is a 0.99-acre emergent wetland at the toe of a levee in a floodplain farm field (see Appendix C, Photo 55). During field delineation in July of 2007, this wetland was not farmed and was completely dominated by two somewhat conservative hydrophytic species, toothcup (Ammania coccinea) and upright burhead (Echinodorus berteroi). Being located in the Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 14 floodplain, this wetland is presumed to be adjacent to the Missouri River and is separated from traditional spring high flows by the man-made levee system. As such, wetland H6-WT-01 is preliminarily identified as a jurisdictional water of the United States.

Wetland J2-WT-01 is a 1.51-acre emergent wetland located in a narrow linear agricultural swale as seen in Appendix C, Photos 85 and 86. Dominant species include horsetail (Equisetum arvense), water heartsease (Polygonum coccineum), straw-colored flatsedge (Cyperus strigosus), and cocklebur (Xanthium strumarium). This wetland is located in the floodplain adjacent to the Missouri River and is thus considered a jurisdictional water of the United States.

Wetland J4-WT-02 is a small (0.04 acres) emergent wet area at the base of the levee in the floodplain adjacent to the Missouri River. As such, this wetland has been preliminarily identified as a jurisdictional water of the U.S. Dominant hydrophytic species include barnyard grass, reed canary grass, straw-colored flatsedge, and smartweeds. Images of this wetland are presented in Appendix C, Photos 95 and 96.

The following emergent wetlands can be identified on Figure 4-1. Associated data sheets and photos are included in Appendix A and C, respectively. Additional information, including a qualitative functional assessment, can be found in Table 4-1.

E5-WT-01 is dominated by black willow with an understory of reed canary grass and Virginia wild rye.

Wetland G5-WT-01 (Appendix C, Photo 41) is a 0.19-acre PFO that directly abuts unnamed perennial (or near perennial) stream G5-SC-02, a tributary of Logan Creek which is a perennial tributary of the Missouri River. As such, G5-WT-01 is considered a jurisdictional water of the U.S. G5-WT-01 is dominated by black willow and silver maple.

Wetland H5-WT-01 (Appendix C, Photo 47) is a 0.48-acre PFO that directly abuts Logan Creek which is a perennial tributary of the Missouri River. As such, H5-WT-01 is considered a jurisdictional water of the U.S. H5-WT-01 appears to be a relict channel of Logan Creek and is dominated by black willow, silver maple, green ash (Fraxinus pennsylvanica), box elder (Acer negundo), and also includes buttonbush in places.

H5-WT-03 (Appendix C, Photo 49) is a 0.09-acre PFO that is located adjacent to and south of the KATY Trail and is connected via a ditch line to Logan Creek, a perennial tributary of the Missouri River. As such, H5-WT-03 is considered a jurisdictional water of the U.S. Common hydrophytic species include silver maple, black willow, and buttonbush.

Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 15 H5-WT-04 (Appendix C, Photo 50) is a 0.29-acre PFO that is connected via a drainage swale to unnamed intermittent stream H5-SC-01 which is tributary to Logan Creek, a perennial tributary of the Missouri River. As such, H5-WT-04 is considered a jurisdictional water of the United States. Common hydrophytic species include silver maple, black willow, and buttonbush.

H5-WT-05 (Appendix C, Photo 51) is a 0.68-acre PFO that is located in a swale between two farm fields in the Logan Creek floodplain. This wetland is adjacent to and connected with Logan Creek via a drainage swale. Because it is ultimately connected to the traditionally navigable waters of the Missouri River, via Logan Creek, H5-WT-05 is considered a jurisdictional water of the United States. Common hydrophytic species include silver maple, black willow, peach-leaved willow, and box elder.

H8-WT-01 (Appendix C, Photos 60, 61, and 62) is a 4.49-acre PFO adjacent to the Missouri River near the existing cooling water intake structure. Because it is adjacent to the traditionally navigable waters of the Missouri River, H8-WT-01 is considered a jurisdictional water of the United States. Common hydrophytic species include cottonwood, black willow, sedges, and Virginia wild rye.

I7-WT-01 is a small (0.06 acres) PFO located in a low depression on the river side of the levee on the left descending bank of the Missouri River. Because it is adjacent to the traditionally navigable waters of the Missouri River, I7-WT-01 is considered a jurisdictional water of the United States. This wetland is dominated by cottonwood, silver maple, and black willow.

Images of this wetland are presented in Appendix C, Photos 69 and 70.

I8-WT-01 (0.04 acres), I8-WT-02 (0.53 acres), and I8-WT-03 (0.23 acres) are PFO wetlands co-located on the river side of the levee approximately 0.5 miles upstream of the cooling water intake structure on the left descending bank of the Missouri River. Because they are adjacent to the traditionally navigable waters of the Missouri River, these wetlands are considered jurisdictional waters of the United States S. Dominant species include black willow, peach-leaved willow, sandbar willow, cottonwood, and sycamore. Images of I8-WT-01, I8-WT-02, and I8-WT-03 are presented in Appendix C, Photos 71 - 75.

J3-WT-03 (Appendix C, Photos 90, 91 and 92) is a 2.98-acre PFO wetland located on the river side of the levee on the left descending bank of the Missouri River. Because it is adjacent to the traditionally navigable waters of the Missouri River, J3-WT-03 is considered a jurisdictional water of the United States. This wetland is dominated by cottonwood, silver maple, and black

willow.

J5-WT-01 (Appendix C, Photos 99 and 100) is a 0.67-acre PFO wetland located in a swale on the river side of the levee on the left descending bank of the Missouri River. Because it is adjacent to the traditionally navigable waters of the Missouri River, J5-WT-01 is considered a jurisdictional water of the United States. This wetland is dominated by silver maple, box elder and sycamore.

J6-WT-01 (Appendix C, Photos 101-104) is a 2.55-acre PFO wetland located in a long, linear swale on the river side of the levee on the left descending bank of the Missouri River. Because it is adjacent to the traditionally navigable waters of the Missouri River, J6-WT-01 is considered a jurisdictional water of the United States. This wetland is dominated by silver maple, box elder, sycamore, and cottonwood.

Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 16 J7-WT-01 (Appendix C, Photo 105) is a 1.58-acre PFO wetland located in another long, linear swale on the river side of the levee on the left descending bank of the Missouri River. Because it is adjacent to the traditionally navigable waters of the Missouri River, J7-WT-01 is considered a jurisdictional water of the United States. This wetland is dominated by black willow, cottonwood, and silver maple.

J7-WT-02 is a 2.10-acre PFO wetland located on the river side of the levee on the right descending bank of the Missouri River in Osage County. This wetland is located within the proposed transmission line corridor for the new Unit 2 facilities planned for the Callaway Plant.

Because it is adjacent to the traditionally navigable waters of the Missouri River, J7-WT-02 is considered a jurisdictional water of the U.S. At the time of field delineation in July of 2007, approximately six inches of new sediment had been deposited from the spring floodwaters and desiccation cracks were abundant. J7-WT-02 is dominated by black willow, peach-leaved willow, cottonwood, box elder, and silver maple.

These ponds range in size from 1.74 acres (P-3) to 14.94 acres (P-6) and were constructed during Unit 1 construction as impoundments or catch basins on the small unnamed streams radiating away from the plant. Some of the stormwater ponds have developed an emergent (PEM) or scrub-shrub (PSS) wetland fringe consisting of American lotus (Nelumbo lutea), cattails, sedges, and occasional black and peach-leaved willows. Because they are located in the headwaters of the various stream systems in the area, the stormwater ponds have played a valuable role in controlling runoff and retaining sediment. Stormwater runoff ponds P-1, P-2, P-7, and P-8 are actively managed by the Missouri Department of Conservation (MDC) and are open to the public for fishing.

Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 17 Stormwater runoff pond P-1 is isolated and, thus, is not a jurisdictional water of the United States. Because stormwater ponds P-2 through P-8 have surface water connections to unnamed streams which eventually flow into named streams and then to the Missouri River, these stormwater ponds are considered jurisdictional waters of the U.S. as follows: P-2 flows into unnamed intermittent stream D3-SC-01 which flows to Mud Creek, a tributary of Logan Creek, which is tributary to the traditionally navigable waters of the Missouri River. P-3 flows into unnamed intermittent stream D4-SC-03 which flows into unnamed intermittent stream E4-SC-01 which flows to Mud Creek, a tributary of Logan Creek, which is tributary to the traditionally navigable waters of the Missouri River. P-4 flows into unnamed intermittent stream C4-SC-02 which joins unnamed intermittent stream C3-SC-02 and flows north into Cow Creek, a tributary of Auxvasse Creek, which is tributary to the traditionally navigable waters of the Missouri River. P-5 flows into unnamed intermittent stream B4-SC-01 which flows through Canyon Lake to the north before discharging to Cow Creek, a tributary of Auxvasse Creek, which is tributary to the traditionally navigable waters of the Missouri River. P-6 flows into an unnamed intermittent stream which flows northeast into the upper, intermittent reaches of Logan Creek which is tributary to the traditionally navigable waters of the Missouri River. P-7 flows into an unnamed intermittent stream which flows northeast into the upper, intermittent reaches of Logan Creek which is tributary to the traditionally navigable waters of the Missouri River. P-8 flows into an unnamed intermittent stream which flows north into Logan Creek which is tributary to the traditionally navigable waters of the Missouri River.

Mud Creek is just outside the study area but receives flow from several unnamed intermittent streams southwest of the plant. Mud Creek is a perennial tributary of Logan Creek (see Figure 4-1, Sheet H5) which is a perennial tributary of the Missouri River.

Logan Creek (Figure 4-1, G5-SC-01, H5-SC-02, H5-SC-03, and H6-SC-01) is the largest perennial stream in the study area besides the Missouri River. In the lowest reaches Logan Creek water levels are generally dictated by Missouri River water levels. In this landscape position Logan Creek is wide with sluggish flow and has a silt/clay/gravel substrate. The dominant riparian zone species present include silver maple (Acer saccharinum), cottonwood (Populus deltoides), box elder (Acer negundo), sycamore (Platanus occidentalis), and Virginia wild rye (Elymus virginicus). Higher in the watershed, Logan Creek substrates transition more predominantly to gravel and cobble. Many unnamed streams east of the plant are tributary to Logan Creek which is tributary to the Missouri River. Site specific data at various locations along Logan Creek is available in Appendix B (G5-SC-01, H5-SC-02, H5-SC-03, and H6-SC-01) and images are available in Appendix C, Photos 42, 53, 54, and 59.

Auxvasse is a large perennial stream to the west of the study area and is a direct tributary of the Missouri River. Auxvasse Creek receives flow from several unnamed intermittent streams north of the Callaway Plant as described below.

G5-SC-02, G5-SC-03, and G5-SC-04 all represent data points along the same unnamed tributary of Logan Creek. This stream is perennial, or near perennial, and has a width at OHWM of approximately 12 feet with gravel/cobble substrates. Site specific data is available in Appendix B (G5-SC-02, G5-SC-03, and G5-SC-04) and images are available in Appendix C, Photos 43-45.

Intermittent Streams Intermittent streams within the study area typically have higher gradients, gravel/cobble/boulder substrates and contain flowing water only seasonally (spring) or in response to rain events.

Many of these streams are located within deciduous upland forests. The intermittent streams have limited fish populations and provide seasonal breeding areas for amphibians. These streams exhibit a discernable bed and bank and have consistent OHWMs. Data sheets for the intermittent streams are provided in Appendix B and photos are available in Appendix C.

Unnamed intermittent tributaries of Auxvasse Creek include: B4-SC-01 C3-SC-02 C4-SC-01 C4-SC-02 Because of the connection to the traditionally navigable waters of the Missouri River, the unnamed intermittent tributaries of Auxvasse Creek listed above are considered jurisdictional waters of the U.S.

Unnamed intermittent tributaries of Mud Creek include: C3-SC-01 D3-SC-01 D4-SC-03 Preliminary Jurisdictional Determination Report Callaway Nuclear Plant p:\3250085303 callaway permitting\pjd\pjd callaway 6-19-2009.doc 21 D5-SC-01 E4-SC-01 D5-SC-02 Because of the connection to the traditionally navigable waters of the Missouri River, the unnamed intermittent tributaries of Mud Creek listed above are considered jurisdictional waters of the United States.

Unnamed intermittent tributaries of Logan Creek include: C5-SC-01 C5-SC-02 C5-SC-03 F5-SC-01 G5-SC-02 G5-SC-03 G5-SC-04 G5-SC-05 Because of the connection to the traditionally navigable waters of the Missouri River, the unnamed intermittent tributaries of Logan Creek listed above are considered jurisdictional

waters of the U.S.

Ephemeral Streams The ephemeral streams are typically located in the upper-most portions or headwaters of their respective watersheds and consist of small upland drainages that contain flowing water only in response to precipitation events. They may, however, contain standing water pools for longer time periods, providing some wildlife benefit functions. These streams exhibit a discernable bed and bank and have somewhat consistent OHWMs. Data sheets for the ephemeral streams are provided in Appendix B and photos are available in Appendix C.

Unnamed ephemeral tributaries of Mud Creek include: E5-SC-01 H5-SC-01 Because of the connection to the traditionally navigable waters of the Missouri River, the unnamed ephemeral tributaries of Mud Creek listed above are considered jurisdictional waters

of the U.S.

Unnamed ephemeral tributaries of Logan Creek include: D4-SC-01 D4-SC-02 E5-SC-02 Because of the connection to the traditionally navigable waters of the Missouri River, the unnamed ephemeral tributaries of Logan Creek listed above are considered jurisdictional waters

of the United States.
