Bozeman Audi VW Property Wetlands Delineation Report November 2018 1 1.0 Introduction An investigation to identify wetlands was performed at the new location for the Bozeman Audi VW Dealership, on October 31, 2018 for Hyalite Engineers, PPLC. This delineation was conducted as part of the due diligence prior to the new development proposed on this property. The current land use is a commercial business which includes a paved lot and buildings across approximately 3 acres of the total 4.7 acres. This property is located on the eastern side of Bozeman, Montana between Interstate 90 and the Frontage Road in the southeast quarter of Section 8 and the southwest quarter of Section 9, Township 2 South, Range 6 East, in Gallatin County. The purpose of the delineation is to identify areas that satisfy the criteria for wetlands and to delineate their boundaries. A second objective is to provide a preliminary jurisdictional status of the delineated wetlands based on their hydrologic connection to Waters of the United States (WOUS). This report presents the process utilized to determine the occurrence of wetlands and provides a map showing the distribution of wetlands and includes the environmental context within which they occur. It should be noted that the U.S. Army Corps of Engineers (USACE) and the U.S. Environmental Protection Agency (EPA) reserve the right to determine jurisdiction on a case-by-case basis (CFR Vol. 51 No. 219). Statements within this report regarding jurisdictional status are preliminary until confirmed by USACE. 1.1 Site Description The property is located within the city limits on the east end of Bozeman. The lot is bordered to the west and east by commercial businesses and to the north by paved county highways, railroad tracks and the riparian corridor of Rocky Creek and the East Gallatin River. Interstate 90 is located along the southern side of the property. The undeveloped portion of the lot is a mix of common tansy, a state-listed noxious weed, lawns and a combination of wetlands and disturbed uplands along the eastern and southern portion of the property. There are signs/remnants of vehicle tracks across the lot in the southeast corner. 2.0 Regulatory Setting Placement of dredged or fill material into wetlands or other “waters of the United States” is regulated by USACE and EPA under Section 404 of the federal Clean Water Act (CWA). 2.1 Wetland Definition For delineation purposes, wetlands are defined as: “Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (33 CFR 328.3, 40 CFR 230.3). The interaction of wetland hydrology, hydrophytic vegetation and hydric soil results in the development of site characteristics unique to wetlands. Consequently, except under certain circumstances, the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (USACE, 2010) requires that a minimum of one positive indicator from each of these three parameters be documented to positively delineate an area as a wetland. In general terms, rivers, streams or drainage ways with a definable bed and bank are Bozeman Audi VW Property Wetlands Delineation Report November 2018 2 designated as waters of the U.S. under Section 404 of the Clean Water Act. In the absence of wetlands, the limit of USACE’s jurisdiction is where the ordinary highwater mark is no longer perceptible (CWA Sec. 328.4 (b)). Ditches, open water areas and similar areas are not wetlands, but may be regulated by USACE and EPA as waters of the United States. 2.2 Waters of the U.S. Definition According to USACE rules, WOUS generally include: waters which were or could be used for interstate or foreign commerce; all interstate waters including interstate wetlands; all other waters including intrastate lakes, river, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use or degradation of which could affect interstate or foreign commerce; all impoundments of waters otherwise defined as waters of the U.S.; tributaries of aforementioned waters; territorial seas; and wetlands adjacent to aforementioned waters (other than wetlands). 2.3 Regulatory Jurisdiction On August 27, 2015, EPA and USACE jointly released a new rule – Definition of Waters of the U.S. Under the Clean Water Act – that amended the definition of “waters of the U.S.” and expanded the range of waters that fall under federal jurisdiction. Since publication of the new rule in the Federal Register, numerous lawsuits have been filed challenging the regulations. On October 9, 2015, the U.S. Court of Appeals for the Sixth Circuit stayed the Clean Water Rule nationwide pending further action of the court. In response to this decision, EPA and USACE resumed nationwide use of the agencies prior regulations defining the term “waters of the United States”. This report uses EPA and USACE guidance that was issued in 2007/2008, which has guided agency interpretation of the Court’s ruling. On June 5, 2007, EPA and USACE issued a joint guidance memorandum that further refined “jurisdiction over waters of the United States under the Clean Water Act” (33 U.S.C. § 1251 et seq) and implements the Supreme Court's decision in the consolidated cases of Rapanos v. United States and Carabell v. United States (126 S. Ct. 2208-2006 (EPA/USACE, 2007a). In addition, the procedures included in this memorandum replace the coordination procedures contained in the January 2003 EPA/Army guidance implementing the SWANCC decision (but leaves the remainder of that guidance unaffected) (EPA/USACE, 2007b). Further, this memorandum does not nullify or supersede the 1990 Geographic Jurisdiction Memorandum of Agreement, including its special case provisions (EPA/USACE, 2007b). A summary of the June 5, 2007 EPA/USACE Memorandum is provided in Table 1. Table 1. Summary of the 2007 EPA/USACE Memorandum The agencies will assert jurisdiction over the following waters: • Traditional navigable waters • Wetlands adjacent to traditional navigable waters • Non-navigable tributaries of traditional navigable waters that are relatively permanent where the tributaries typically flow year-round or have continuous flow at least seasonally (typically three months) • Wetlands that directly abut such tributaries The agencies will decide jurisdiction over the following waters based on a fact-specific analysis to Bozeman Audi VW Property Wetlands Delineation Report November 2018 3 determine whether they have a significant nexus with a traditional navigable water: • Non-navigable tributaries that are not relatively permanent • Wetlands adjacent to non-navigable tributaries that are not relatively permanent • Wetlands adjacent to but that do not directly abut a relatively permanent non-navigable tributary The agencies generally will not assert jurisdiction over the following features: • Swales or erosional features (e.g., gullies, small washes characterized by low volume, infrequent or short duration flow) • Ditches (including roadside ditches) excavated wholly in and draining only uplands and that do not carry a relatively permanent flow of water The agencies will apply the significant nexus standard as follows: • A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by all wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical and biological integrity of downstream traditional navigable waters • Significant nexus includes consideration of hydrologic and ecologic factors 3.0 Methods 3.1 Review of Existing Materials A review of existing literature, maps and other materials was conducted to identify wetlands and other waters of the U.S. including: • National Wetland Inventory mapping (USFWS) • Montana Natural Heritage Program (Local) Wetland Inventories (MTNHP) • Soil Survey of Gallatin County (NRCS, 2018) • Hydric Soils, Gallatin County (NRCS, 2018) 3.2 Field Methods The delineation was conducted in accordance with the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual (Environmental Laboratory, 1987) and the Western Mountains, Valleys, and Coast Regional Supplement (USACE, 2010). Except under certain circumstances, these documents require the simultaneous presence of wetland hydrology, hydric soils and a dominance (greater than 50 percent) of hydrophytic vegetation during the growing season to positively delineate an area as a wetland. 3.2.1 Hydrology To evaluate hydrologic characteristics, primary and secondary indicators were investigated at each of the delineation sample points. Primary indicators included the presence of saturation within the upper 12 inches. Secondary indicators generally included geomorphic position and a positive facultative (FAC)-neutral test. The delineation was conducted during the fall under relatively normal climatic conditions. The presence of indicators such as soil saturation were assumed to be accurate representations of typical fall hydrologic conditions. Bozeman Audi VW Property Wetlands Delineation Report November 2018 4 3.2.2 Soils Soils at each representative wetland and upland sample point were typically inspected to a depth of at least 18 inches to determine the presence or absence of hydric soil indicators based on the Natural Resource Conservation Service (NRCS) Indicators of Hydric Soils (Version 7.0, NRCS, 2010). Soil samples were moistened when necessary to aid in the determination of soil matrix and redoximorphic features (if present), hue, value and chroma using Munsell Soil Color Charts (Munsell, 2009). Soil texture was evaluated using field methods described by USACE and NRCS. 3.2.3 Vegetation At each sample point, plant species dominance was visually estimated based on the percent aerial cover for each species and then recorded. Herbaceous cover was assessed within a 5-foot radius circular plot (Environmental Laboratory, 1987, USACE, 2010). In accordance with USACE methodology, greater than 50 percent of the dominant plant species must be classified as hydrophytic for an area to be a wetland. The indicator status for vegetation was derived from the Western Mountains, Valleys, and Coast: 2016 Regional Wetland Plant Lists (Lichvar et al., 2016). Accordingly, plants may be categorized as obligate (OBL), facultative wetland (FACW), facultative (FAC), facultative upland (FACU) or upland (UPL). If a species does not have an indicator status due to insufficient information available to determine an indicator status, a no indictor (NI) designation is utilized. The presence of hydrophytic vegetation within a representative plant community is positively identified if more than 50 percent of the dominant species within the community have an indicator status of OBL, FACW or FAC, or has a prevalence index of less than 3.00 for a site to display a positive wetland vegetation indicator. At each sample point, plant species dominance was estimated based on the percent aerial coverage within the community type being sampled. Soil pits were generally excavated to a depth of at least 18 inches, with horizons, soil textures and hydric soil indicators recorded. The sample point locations were marked in the field with pin flags and surveyed. For each wetland and upland sample point, USACE Wetland Determination Data Forms were completed (Appendix B). The wetland boundaries were marked using a combination of sequentially numbered pin flags. All pin flag locations were mapped by Hyalite Engineers. The project area Wetland Figure is included in Appendix A. Representative photographs were taken of the wetlands and are included in Appendix C. In addition to the formal sample or data plots that were recorded and photographed, several additional soil pits were dug along the wetland/upland boundaries to provide an accurate delineation. The soil pit results were not formally documented but rather used to confirm results of the sampled data plots throughout the wetland and uplands. 3.3 Stream Channels and other Non-Wetland Waterways According to the 2002 Nationwide Permits and Conditions (Federal Register 67:10, January 15, 2002) “Areas where wetland vegetation is not present should be determined by the presence or absence of an ordinary highwater mark or bed and bank”. Applying this general guidance, natural drainage features not satisfying wetland criteria were delineated as non-wetland waterways if they exhibited a clear bed and bank/ordinary high watermark. Bozeman Audi VW Property Wetlands Delineation Report November 2018 5 3.4 Wetland Classification Sample points and wetlands were assigned unique identifiers, photographed and primarily characterized according to the hydrogeomorphic (HGM) classification method (Smith et al., 1995) and USFWS classification (Cowardin et al., 1979). The HGM classification is based on geomorphic (landscape) setting, water source and hydrodynamics (Smith et al., 1995). A brief description of each wetland type is presented below. • Slope wetlands occur on sloping land where groundwater is discharging to the ground surface principal water sources are groundwater discharge, interflow from surrounding uplands, and precipitation. • Depression wetlands occur in topographic depressions that allow the accumulation of surface water and may be closed basins or may have outlets and/or inlets. For depression wetlands, dominant water sources are precipitation, high groundwater, groundwater discharge and interflow from adjacent uplands (Smith et al., 1995). 3.5 Rational Used in Preliminary Jurisdictional Determinations Wetlands were identified as those areas exhibiting wetland hydrology, hydric soils and a dominance of hydrophytic vegetation. Non-wetland waterways were identified as scoured channels that conduct water at least once during the year and a) lack at least one of the wetland criteria or b) may support an extremely narrow, often sporadic, wetland fringe. All such areas encountered in the project area were delineated, regardless of their preliminary jurisdictional status. All wetlands and non-wetland waterways were followed on foot until they physically joined with a WOUS, joined with a continuous tributary to a known WOUS or ended in an upland. The preliminary jurisdictional status of wetlands and non-wetland waterways were based on their perceived adjacency or ultimate surface water connection (i.e., a significant nexus) to a presumed traditionally navigable WOUS. Significant nexus for wetlands were established by considering hydrologic and ecological factors such as volume, duration and frequency of flows, or potential to carry pollutants and flood waters to traditional navigable waters, as well as other considerations (EPA and COE 2007a). As the regulatory authority, the USACE will make all final jurisdictional determinations. TREC personnel, based on consultation with USACE, uses a measurable distance of 150 feet between wetlands and waterways to indicate “adjacency”. Other factors taken into consideration included topography/land form, frequency of flow and potential for overland flows between a wetland and a known WOUS. Wetlands and non-wetland waterways were classified as “likely non-jurisdictional” if they were clearly isolated, located at least 150 feet from an adjacent wetland, terminated in undisturbed upland with no intermittent or perennial surface waterway connection to a known WOUS and were not considered adjacent as defined previously. Wetlands were classified as “likely jurisdictional” if they were contiguous with a known WOUS or perennial, intermittent, or ephemeral tributary to a known WOUS. Non-wetland waterways were considered as likely jurisdictional if they were perennial or intermittent tributaries to a known WOUS. As described above, 150 feet was the distance utilized to indicate adjacency for jurisdictional purposes. As a result, “likely jurisdictional” status was extended to wetlands that were Bozeman Audi VW Property Wetlands Delineation Report November 2018 6 less than 150 feet from likely jurisdictional wetlands or waterways if there was a conceivable surface water connection between the two at least once per year. 4.0 Results A total of seven (7) sample points were evaluated within the project area. A detailed description of the wetlands and sample points are provided in the following section. Representative photographs are labeled and included in Appendix C. 4.1 Wetland Delineation Two wetlands covering 0.36 acres were delineated on October 31, 2018 across the property. The delineated wetlands are shown on the Wetland Figure, Appendix A. The classification, acreage, preliminary jurisdictional status and narrative description is summarized for the wetlands in Table 2, and Sections 4.1.5 and 4.1.6. Common wetland and upland plants observed within the project area are listed in Table 3. 4.1.1 Wetland Boundaries Wetland boundaries were generally identifiable due to changes in topography, shifts in vegetation dominance from FAC or wetter species to FACU or drier species, changes in hydrology and/or changes in soil types. Slight changes in topography were used to help identify depressional wetland boundaries and upland margins. Shifts in plant species composition toward drier species such as smooth brome (Bromus inermus), common tansy (Tanacetum vulgare) and common snowberry (Symphoricarpos albus) also assisted with boundary determinations. 4.1.2 Soils The Natural Resource Conservation Service (NRCS) has identified one map unit or soil type within the delineation area (NRCS, 2018). Each map unit is typically composed of one or more soil types and NRCS has rated the percentage of each soil type that meets the criteria for hydric soils. Listed below is the soil type identified for the project area with its hydric rating (percentage). • 523A-Enbar Nythar loams, cool, 0 to 4 percent slopes (22 percent hydric soils). Detailed soil descriptions for the wetlands and uplands are provided on the delineation data forms in Appendix B. 4.1.3 Vegetation A comprehensive list of plant species identified within the project boundary, along with their indicator status, is provided in Table 3. The dominant plant species found in the wetland and upland areas are described in Sections 4.1.5, 4.1.6 and 4.1, respectfully, and on the delineation data forms (Appendix B). 4.1.4 Hydrology Primary wetland hydrology indicators were observed throughout all areas identified as wetlands. These primary wetland indicators included saturation within the upper twelve inches in wetlands (see completed data forms in Appendix B). Depressional wetlands appeared to receive their hydrologic input primarily from overland runoff and seasonal high groundwater. Bozeman Audi VW Property Wetlands Delineation Report November 2018 7 4.1.5 Palustrine Emergent Wetland (PEM) WL-1 Wetland 1 is a palustrine emergent wetland representing 0.32 acres or 14,066 sq. ft within the property boundary. Palustrine emergent wetlands are described as wetlands with erect, rooted herbaceous vegetation present during most the growing season. This wetland is further classified as depression/slope supported by seasonal high groundwater and surface water runoff. WL-1 includes a well vegetated shallow wetland swale (see photograph 5, Appendix C) along the southern property boundary that extends to the west and ends at the Subaru Dealership and the KOA campground corner; the swale continues (dominated by upland vegetation) north ending near the Frontage Road. There is a culvert under the Frontage Road but no channel or bed and bank. The majority of WL-1 is a depressional wetland in the southeast corner of the lot that extends to the north and east along the interstate fence. The wetland continues east, off property, ending in an aspen grove on the eastern side of adjacent lot (see Wetland Figure 2, Appendix A). The upland boundaries surrounding WL-1 on the property were generally defined by a slight increase in elevation, changes in soil texture and a shift in vegetation dominance to common snowberry, common tansy, meadow fescue or smooth brome. The wetland vegetation within WL-1 included wheat sedge (Carex atherodes), leafy tussock sedge (Carex aquatilis), creeping foxtail (Alopecurus arundinaceus), bitter dock (Rumex obtusifolius), Kentucky bluegrass (Poa pratensis) and Nebraska sedge (Carex nebrascensis). The wetland soils are predominantly a loam or clay loam with matrix hues of 10YR and 7.5YR, matrix value of 2.5 or 3 and matrix chroma of 1 or 2. Redox concentrations were generally noted within the upper 5 to 6 inches. Hydric soil indicators were generally a depleted dark surface (F6). Wetland hydrology was confirmed by the presence of primary indicators including saturated soils. 4.1.6 Palustrine Emergent Wetland (PEM) WL-2 Wetland 2 represents 0.04 acres, or 1,788 sq. ft of palustrine emergent wetland located within the Frontage Road right-of-way and lot boundary. Dominant vegetation within WL-2 included primarily wheat sedge and Canada thistle. Several feet to the east, a small patch of bitter dock was noted within the wetland depression. The wetland soils are predominantly a clay loam with matrix hues of 7.5YR, matrix value of 3 and matrix chroma of 1. Redox concentrations for WL-1 were noted at 6 inches and hydric soil indicators were generally a redox dark surface (F6). Wetland hydrology was confirmed by the presence of saturation to the surface.

These sample points were used to assist in establishing wetland boundaries and to determine/verify upland areas. Taken throughout the project area, these sample points varied throughout the upland areas which generally occurred in slightly higher topography bordering the wetland. Common species noted in the uplands included common tansy, smooth brome, meadow fescue (Schedonorus pratensis), creeping foxtail, Kentucky bluegrass and creeping wild rye (Elymus repens). Soils varied from dark brown to a very dark gray while textures ranged from a loam to a rocky loam. Bozeman Audi VW Property Wetlands. Delineation Report November 2018 9 Table 3.

Delineation Report November 2018 10 5.0 Deviations from National and State Wetland Inventories 5.1 National Wetland Inventory (NWI) The US Fish and Wildlife Service (USFWS) NWI did not identify any wetlands or non-wetland waterways within the lot boundary but did map the Rock Creek/East Gallatin River north of the property as shown in Appendix A. Please note that the NWI maps are prepared from the analysis of high-altitude imagery. Wetlands are identified based on suspected vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any site is needed to confine or dispute a wetland, wetland boundary or wetland classification from image analysis. 5.2 Montana Natural Heritage Program Wetland Mapping The Montana Natural Heritage Program (MTNHP) has completed the wetland mapping within the project area. After a review of the wetland online database provided by MTNHP, no wetlands or waterways were noted within or adjacent to the lot. The MTNHP did map the riparian corridor and stream/river channels of Rocky Creek and the East Gallatin River as well. Bozeman Audi VW Property Wetlands. Delineation Report November 2018 11 6.0 Summary As outlined in Table 1, USACE will assert jurisdiction over traditional navigable waters, including all the waters described in 33 CFR 328.3 (a) (1) and 40 CFR 230.3 (a) and will assert jurisdiction over wetlands adjacent to traditional navigable waters, including adjacent wetlands (as previously described) that do not have a continuous surface connection to traditional navigable waters. As the regulatory authority, USACE will make all final jurisdictional determinations. Within the project area, two wetlands were delineated on October 31,2018. WL-1 originates east of the project site and continues west along the southern property boundary before ending at the corner between the KOA Campground and the Subaru Dealership as shown on Wetland Figure 2, Appendix A. From the corner, the vegetated upland swale continues to the north ending near the Frontage Road. No bed and banks, wetlands or channels were noted to the east, north or west. WL-1 ends at the aspen grove on the eastern side of the property adjacent to the lot. TREC’s wetland scientist walked several hundred feet farther to the north and east and evaluated culverts under the Frontage Road and business driveways which consisted of a slight vegetated swale, no bed and bank, and no scour or signs of flowing water were noted leading to the north or west. The distance from WL-1 is approximately 790 feet and there are no connections between the project wetlands and Rocky Creek/East Gallatin River farther to the west or north. WL-2 is located within the Frontage Road right-of-way and is approximately 349 feet from Rocky Creek/East Gallatin River as shown on Wetland Figure 2, Appendix A, these distances and lack of connects were considered when determining preliminary jurisdictional status of the project wetlands. As a result, the two wetlands within the project site are “likely non-jurisdictional” based on the following criteria; they lack a surface connection to a known WOUS; are greater than 150 feet from a WOUS or other jurisdictional wetland; terminate in an upland with no ephemeral, intermittent or perennial surface waterway connection to a known WOUS; and are not considered adjacent/neighboring as previously defined. All final jurisdictional determinations are decided by USACE and EPA. Bozeman Audi VW Property Wetlands.

Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required. This product is generated from the USDA-NRCS certified data as of the version date(s) listed below. Soil Survey Area: Gallatin County Area, Montana Survey Area Data: Version 22, Sep 5, 2018 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Aug 3, 2009—Sep 1, 2016 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

Map units are composed of one or more map unit components or soil types, each of which is rated as hydric soil or not hydric. Map units that are made up dominantly of hydric soils may have small areas of minor nonhydric components in the higher positions on the landform, and map units that are made up dominantly of nonhydric soils may have small areas of minor hydric components in the lower positions on the landform. Each map unit is rated based on its respective components and the percentage of each component within the map unit. The thematic map is color coded based on the composition of hydric components. The five color classes are separated as 100 percent hydric components, 66 to 99 percent hydric components, 33 to 65 percent hydric components, 1 to 32 percent hydric components, and less than one percent hydric components. In Web Soil Survey, the Summary by Map Unit table that is displayed below the map pane contains a column named 'Rating'. In this column the percentage of each map unit that is classified as hydric is displayed. Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS) as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). Under natural conditions, these soils are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation. The NTCHS definition identifies general soil properties that are associated with wetness. In order to determine whether a specific soil is a hydric soil or nonhydric soil, however, more specific information, such as information about the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register, 2002). These criteria are used to identify map unit components that normally are associated with wetlands. The criteria used are selected estimated soil properties that are described in "Soil Taxonomy" (Soil Survey Staff, 1999) and "Keys to Soil Taxonomy" (Soil Survey Staff, 2006) and in the "Soil Survey Manual" (Soil Survey Division Staff, 1993). If soils are wet enough for a long enough period of time to be considered hydric, they should exhibit certain properties that can be easily observed in the field. These visible properties are indicators of hydric soils. The indicators used to make onsite determinations of hydric soils are specified in "Field Indicators of Hydric Soils in the United States" (Hurt and Vasilas, 2006). References: Federal Register.
