1.0 INTRODUCTION

US Magnesium LLC (US Mag or Respondent) is a commercial producer of magnesium and magnesium alloys and operates a facility in Rowley, Tooele County, Utah (Figure 1-1). On 4 August 2011, an Administrative Settlement Agreement and Order on Consent for a Remedial Investigation and Feasibility Study (RI/FS) was entered into by US Mag and United States Environmental Protection Agency (USEPA) Region 8. The Administrative Settlement Agreement and Order on Consent defines the roles, responsibilities, schedule, and administration of the RI/FS to be performed.

In support of the ecological risk assessment (ERA), US Mag and the USEPA have agreed there is a need for current information regarding the habitats and biota that are present within the RI/FS Study Area. For project planning during the initial phases of the RI, the RI/FS Study Area is defined as the area within a 5-mile radius centered on US Mag’s main stack, excluding the operating facility (Figure 1-2). Knowledge of habitats within the RI/FS Study Area will be used to understand the types of ecological receptors that may be potentially exposed to releases and to identify locations where exposures are likely to occur. To achieve the study objectives, two types of data sources for the RI/FS Study Area are proposed: (1) existing information on the habitat types and associated flora and fauna, and (2) field-collected data from specific areas.

This Work Plan describes the goals, scope, methods, and products of the Habitat and Wildlife Survey and Mapping effort (EcoSurvey/Map). Note that additional focused surveys may be considered in the future should findings of this or other ERA-related efforts suggest that supplementary information would be useful in decision-making. Standard operating procedures described in this document will govern all aspects of field survey and mapping efforts to ensure that habitat maps and wildlife- habitat relationships (WHR) are representative of conditions observed/expected in the field and that observations are clearly and concisely documented. This Work Plan was developed to comply with protocols in the Site-Specific Health and Safety Plan (ERM 2012a).

1.1 US MAGNESIUM OPERATING FACILITY

The RI/FS Study Area is located in the Lakeside Valley, a north-south- trending valley bordered by the Great Salt Lake (GSL) to the east and the

ERM 1 US MAGNESIUM/0132320 – JANUARY 2013

Lakeside Mountains to the west (Figure 1-1). The RI/FS Study Area encompasses an active primary magnesium production facility, which has been in operation since 1972. The US Mag operating facility is located approximately 15 miles north of Interstate 80 and 33 miles north of Grantsville, near the southwest edge of the GSL. Elevation at the operating facility is approximately 4,220 feet above mean sea level, or about 8 feet above the maximum-recorded extent of the high lake elevation (Montgomery Watson Harza 2003).

At the US Mag facility, magnesium is refined from brine obtained from the GSL. An aerial photograph of the operating facility is provided on Figure 1-2. The facility includes employee offices and process buildings and other ancillary structures and facilities. Surrounding the process buildings are a series of evaporation ponds, a concentrator pond, a landfill, and waste disposal areas where smut and calcium sulfate are piled. A series of earthen, open-air ditches convey liquid waste from the process facility to earthen wastewater impoundments. An engineered disposal site for cast house residues containing barium sulfate and an inactive waste pond are located northwest and northeast of the facility, respectively. ATI Titanium and Hill Brothers Chemical facilities are located just southwest and south of the operating facility, respectively.

1.2 PRELIMINARY REMEDIATION INVESTIGATION AREAS

For purposes of project planning during the initial phases of the RI, the RI/FS Study Area has been divided into 18 Preliminary Remediation Investigation (PRI) areas. The PRI areas listed below and PRIs 1 through 16 are shown on Figure 1-3:  PRI 1: Ditches  PRI 10: Barium Sulfate Disposal Area  PRI 2: Landfill  PRI 11: ATI Titanium and US Mag Parking Lots  PRI 3: Sanitary Lagoon  PRI 12: Ancillary Worker Exposure Area  PRI 4: Gypsum Pile  PRI 13: Buffer Area Northeast  PRI 5: Southeast Ponded  PRI 14: Buffer Area Southeast Waste Lagoon  PRI 6: Northwest Ponded  PRI 15: Buffer Area Alluvial Waste Lagoon Upland

ERM 2 US MAGNESIUM/0132320 – JANUARY 2013

 PRI 7: Northeast Ponded  PRI 16: Buffer Area Lakeside Waste Lagoon Mountains  PRI 8: Northwest Lagoon  PRI 17: Site-Wide Surface Water Overflow and Groundwater  PRI 9: Smut Area  PRI 18: Site-Wide Ambient Air

Note that PRI boundaries are provided on maps for perspective. Information will be compiled and provided on a habitat-by-habitat basis.

1.3 OVERVIEW OF THE ECOSURVEY/MAP WORK PLAN ORGANIZATION

This EcoSurvey/Map Work Plan is organized as follows:  Section 1: Introduction;  Section 2: Overview of Existing Information;  Section 3: EcoSurvey/Map Data Quality Objectives;  Section 4: Field Survey Design;  Section 5: Field Survey Methods;  Section 6: Mapping Methods;  Section 7: EcoSurvey/Map Documentation; and  Section 8: Literature Cited.

ERM 3 US MAGNESIUM/0132320 – JANUARY 2013

2.0 OVERVIEW OF EXISTING INFORMATION

As described previously, one category of data that will be used to develop habitat maps and species lists for the RI/FS Study Area includes available data. Therefore, in preparation of this Work Plan, readily available data germane to habitats and wildlife species that occur, or are likely to occur, within the RI/FS Study Area were identified, compiled, and reviewed. For example, investigations conducted for US Mag1 were identified and reviewed.

Key sources of habitat and WHR information for this mapping effort included:  Southwest Regional Gap Analysis Project (SWReGAP);  Utah State Geographic Information Dataset (Utah SGID);  Utah Conservation Data Center (Natural Heritage Program);  Utah Department of Natural Resources (UDNR) reports; and  United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS).

SWReGAP was a mapping and assessment of biodiversity for the five- state region encompassing Arizona, Colorado, Nevada, New Mexico, and Utah (United States Geological Survey [USGS] 2007). SWReGAP was to map distributions of natural communities and predicted habitat of native animal species. SWReGAP provides a seamless land cover (habitat) map for Utah and neighboring states. Further, SWReGAP was constructed based on data from several recognized sources (Prior-Magee et al. 2007) and is considered a comprehensive resource for habitat and wildlife data. The SWReGAP dataset has a minimum mapping unit of approximately 1 acre (0.4 hectares) (USGS 2007). SWReGAP is considered to provide sufficient spatial resolution to identify populations and communities of plants and animals in support of the ERA. Accordingly, SWReGAP is considered a preferred source and was the primary basis for the information contained in preliminary habitat map and species lists.

1 Cavitt 2008, 2010; BIO-Logic 2002, 2003, 2004; Stackhouse 2002; Halford et al. 1999; Glover 1983.

ERM 4 US MAGNESIUM/0132320 – JANUARY 2013

Other sources considered during the preparation of this Work Plan included local and regional information associated with vegetation, wildlife, and habitats from various natural resources groups and agencies such as the United States Fish and Wildlife Service, GSL Ecosystem Program, Utah Division of Wildlife Resources, Bureau of Land Management, USGS, and NatureServe.

2.1 GEOLOGY AND SOILS MAPS

Maps of topography and soil types may provide additional information related to the types of vegetation and level of disturbance observed in the field. The topographic maps assist in analysis of elevations and land formations present within the RI/FS Study Area relative to the habitat types and species distribution.

Topographic base maps provided by the USGS were processed and used in Geographic Information System (GIS) by the Utah SGID. Geology and soil maps from the USGS and the USDA NRCS Soil Data Mart are available and will be provided in the EcoSurvey/Map deliverable (Section 7). A map showing the geology within the RI/FS Study Area is provided as Figure 2-1. A map showing soil types within the RI/FS Study Area is provided as Figure 2-2.

2.2 AERIAL PHOTOGRAPHS

Aerial photographs may be used to assist in identifying disturbance to habitats within the RI/FS Study Area (e.g., construction, roads). Historical aerial photographs are available and will be provided in the EcoSurvey/Map deliverable (Section 7). Example historical aerial photographs are provided on Figure 2-3.

2.3 HABITAT MAPS

The operating facility lies in a transition area between (1) playa adjacent to the GSL and (2) uplands that are dominated by arid halophytic shrubs, primarily greasewood, to the west (BIO-Logic 2003). Several habitat types have been identified for the RI/FS Study Area based on the SWReGAP database (Figure 2-4, Table 2-1). Seven habitat types dominate much of the area within the RI/FS Study Area and include (Table 2-2):

ERM 5 US MAGNESIUM/0132320 – JANUARY 2013

 Open Water;  Inter-Mountain Basins Greasewood Flat;  Inter-Mountain Basins Playa;  Invasive Annual Grassland;  Developed (low-/high-intensity);  Great Basin Pinyon-Juniper Woodland; and  Inter-Mountain Basins Semi-Desert Grassland.

Habitat descriptions are provided in Table 2-3.

Open Water of the GSL and Inter-Mountain Basins Playa are the dominant habitats in buffer areas to the northeast (PRI 13) of the operating facility (Figure 2-5). Inter-Mountain Basins Greasewood Flat, Inter-Mountain Basins Playa, and Open Water of the GSL are the dominant habitats in buffer areas to the southeast (PRI 14) of the operating facility (Figure 2-6).

Inter-Mountain Basins Greasewood Flat and Invasive Annual Grassland are the dominant habitats in the buffer area located in the Lakeside Valley to the northwest, west, and southwest (PRI 15) of the operating facility (Figure 2-7). Invasive annual and biennial forbland are found scattered in this area, as well.

Invasive Annual Grassland and a variety of Inter-Mountain Basins habitats are found in the buffer area located in the Lakeside Mountains and foothills west (PRI 16) of the operating facility (Figure 2-8). Great Basin Pinyon-Juniper Woodland habitat is found in areas located in the higher regions of the Lakeside Mountains.

Recent surveys at the US Mag facility focused primarily on wildlife and not on habitat. From SWReGAP, Open Water and Developed (both low- and high-intensity) are the dominant habitat types for waste management areas surrounding the operating facility, ancillary developed areas, and the adjacent Hill Brothers and ATI properties (PRIs 1 through 12)— i.e., areas immediately surrounding the operating facility (Figure 2-9). Open water observed at the operating facility primarily occurs in ditches and in active/inactive wastewater lagoons used for operations. BIO-Logic (2003) described these lagoons as being “… enclosed by dikes that create ribbons of playa and upland habitat extending into open water areas.”

ERM 6 US MAGNESIUM/0132320 – JANUARY 2013

Note that the SWReGAP assigned the Open Water habitat type to industrial waste lagoons (PRIs 5 through 7). SWReGAP’s Open Water habitat description is terse (Table 2-3) and can be applied to a variety of surface water body types. A single categorization may be an oversimplification for the purposes of supporting the ERA.

In addition, the SWReGAP description for the Developed habitat classification is applicable for environs generally indicative of residential and/or commercial land uses (Table 2-3). Dykes and upland areas surrounding wastewater lagoons at the site have been observed to provide suitable habitat for wildlife (BIO-Logic 2003; Paramatrix 2003). In addition, there exist isolated areas of minimally disturbed or reclaimed land within the active US Mag facility that may provide suitable habitat for wildlife. Hence, the SWReGAP Open Water and Developed habitat designations may not provide sufficient detail for specific locations within the US Mag property boundaries or there may be areas where the Open Water or Developed habitat classifications do not adequately describe the characteristics of the area (e.g., a residential or commercial classification may be inaccurate for the gypsum pile at PRI 4).

2.4 WILDLIFE-HABITAT RELATIONSHIP

SWReGAP2 developed WHR models for 819 vertebrate species that reside, breed, or use habitat for a substantial portion of their life history in the five-state region of Arizona, Colorado, Nevada, New Mexico, and Utah, including amphibians (37 species), reptiles (130 species), birds (437 species), and mammals (215 species). Accordingly, SWReGAP was considered to provide the most comprehensive species-habitat relationships for vertebrates occurring within the RI/FS Study Area and served as the primary source for the species lists described herein. Based on the SWReGAP database, approximately 800 species are associated with habitats that may occur within the RI/FS Study Area. As reported by SWReGAP, the number of species associated with each habitat type within the RI/FS Study Area is listed in Table 2-4.

2 The 2005 version of a relational database was procured from one of the SWReGAP authors (Dr. Ken Boykin) for this project. (SWReGAP http://fws-nmcfwru.nmsu.edu/swregap/).

ERM 7 US MAGNESIUM/0132320 – JANUARY 2013

2.4.1 Sensitive Species

Consistent with Berryman Institute et al. (1998) and UDNR (2011), sensitive species include:  Federal-listed threatened, endangered, or candidate species;  State-listed threatened, endangered, or candidate species;  Utah wildlife species of concern; and  Utah species of greatest conservation need.

The numbers of sensitive species associated with each habitat type within the RI/FS Study Area are listed in Table 2-5. The names of federal- and state-listed endangered, threatened, or candidate species by habitat type within the RI/FS Study Area are listed in Table 2-6. The names of state species of special concern and/or of conservation interest by habitat type within the RI/FS Study Area are listed in Table 2-7.

2.4.2 Species Lists

Species lists of plants, invertebrates, amphibians, reptiles, birds (including migratory birds), and mammals characteristically associated with habitats that occur within the RI/FS Study Area were assembled and are included in Appendix A. To support the ERA, species for each habitat type were categorized according to the following taxonomic groups:  Plants;  Invertebrates;  Amphibians;  Reptiles;  Birds; and  Mammals

These species lists include:  Common species name;  Scientific species name;  Associated habitat type;  Special status;

ERM 8 US MAGNESIUM/0132320 – JANUARY 2013

 Abundance in or use of habitat (e.g., breeding ground, migratory, dominant); and  PRI in which each species-habitat combination could be found.

Note that the Developed habitat classification is generally assigned to environs indicative of residential and commercial use. Hence, the SWReGAP WHR model for Developed habitat type may not be indicative of wildlife relationships for areas immediately surrounding the operating facility (PRIs 1 through 12).

2.5 KEY INFORMATION GAP

From the late 1990s to the present, use of GIS-based wildlife-habitat models have become conventional, standard practice (Scott et al. 2002; Guisan and Thuiller 2005). An analysis of the accuracy of SWReGAP examined site features at 382 randomly selected sample locations in the Southwestern United States to assess the degree of concordance with features used in modeling vertebrate habitat distributions (Boykin et al. 2010). While a greater than 60 percent overall agreement was found for the 19 variables examined, there were no differences detected in concordance among taxa groups, degree of specialization or generalization of selected taxa, or land conservation categorization of sample sites for all locations evaluated in the analysis. Boykin et al. (2010) noted that these patterns demonstrated the resilience of gap analysis deductive model processes for remotely sensed or interpreted data used to predict habitat features. On this basis, SWReGAP is considered sufficient to identify types of biotic receptors for the ERA, especially for minimally disturbed habitats in buffer areas (PRIs 13 through 16).

Areas immediately surrounding the operating facility are likely to be included when determining/identifying potential exposure areas for the ERA. SWReGAP has assigned the Open Water habitat type to waste lagoons and the Developed habitat type to all upland land covers in these areas. The Open Water habitat type will likely need to be qualified to reflect the industrial use and disturbed nature of these surface water impoundments. With respect to the Developed habitat type, a single categorization may be an oversimplification for the purposes of supporting the ERA. For example, from a recent site visit and review of aerial photographs, it appears that the Developed habitat type assigned to PRIs 1 through 12 may categorize land cover ranging from barren ground to greasewood flat habitat (albeit not pristine). However, SWReGAP’s

ERM 9 US MAGNESIUM/0132320 – JANUARY 2013

Developed habitat type designation is typically assigned to environs indicative of residential and commercial land uses (e.g., landscaped single family homes, golf courses, etc.) (Table 2-3). Therefore, for areas immediately surrounding the operating facility, the WHR model for Developed habitat may not be appropriate for supporting the ERA— i.e., species associated with residential/commercial land cover may not be appropriate for areas within PRIs 1 through 12. Hence, the designation of the Developed habitat type in areas immediately surrounding the operating facility is considered to be a key uncertainty/data gap when identifying receptor types in support of the ERA.

In summary, significant habitat and species data exist for the RI/FS Study Area. Based on a review of these data, SWReGAP is considered adequate for mapping habitat types and to identify types of biotic receptors for the ERA in the buffer areas (PRIs 13 through 16). However, the SWReGAP habitat designations for PRIs 1 through 12 will require further refinement for the ERA.

ERM 10 US MAGNESIUM/0132320 – JANUARY 2013

3.0 ECOSURVEY/MAP DATA QUALITY OBJECTIVES

The data quality objective process provides the systematic basis for designing a plan for effectively collecting data that are of the appropriate type, quantity, and quality to support their expected use (USEPA 2006). Information for the development of data quality objectives for this survey was provided by the USEPA Region 8. This information has been slightly modified and is discussed further in this section.

3.1 STEP 1: STATE THE PROBLEM

The US Mag operating facility is located within an ecosystem comprising aquatic and terrestrial habitats that support a variety of plants, invertebrates, amphibians, reptiles, birds, and mammals. To support risk analyses conducted as part of the ERA, it is important to know the location of habitat and types of plants and animals that may be exposed to constituents released from the US Mag facility. In addition, the single categorization of Developed habitat type assigned to areas immediately surrounding the operating facility (PRIs 1 through 12) is considered to be an oversimplification and is a key uncertainty/data gap for the purposes of supporting the ERA.

3.2 STEP 2: IDENTIFY THE GOALS

The overall goal of the EcoSurvey/Map effort is to map habitats and identify types of biotic receptors within the RI/FS Study Area in sufficient detail to support the analyses conducted as part of the ERA. The EcoSurvey/Map is comprised of two main tasks: 1. Field survey (Sections 4 and 5); and 2. Mapping of habitat and wildlife (Section 6).

To meet the overall goal of the EcoSurvey/Map, maps of habitat and identification of the types of biotic receptors within the RI/FS Study Area will be based on (1) existing SWReGAP maps and WHRs and (2) field observations of habitats and biotic receptors.

ERM 11 US MAGNESIUM/0132320 – JANUARY 2013

3.2.1 Field Survey

To assist in establishing sensible goals for the field survey effort in support of the ERA, the following questions and responses were considered:

Question Response 1. Can observations from the Unlikely. Confirming the absence of field survey eliminate listed threatened/endangered species would species from further require detailed surveys using United consideration? States Fish and Wildlife Service protocols specific for each listed species. Such an effort is considered beyond the scope of this initial EcoSurvey/Map effort. The ERA will assume listed species occur in habitats within the RI/FS Study Area as documented by WHRs and the Natural Heritage Program or as observed from site-specific investigations. 2. In minimally disturbed Unlikely. Confirming the absence of habitats, can observations non-listed species in minimally from the field survey disturbed habitats within the RI/FS eliminate non-listed species Study Area would require detailed from further consideration? surveys on a habitat-by-habitat basis throughout the year and repeated for more than 1 year. This effort is considered beyond the scope of this initial EcoSurvey/Map effort. The ERA will assume non-listed species occur in minimally disturbed habitats within the RI/FS Study Area unless refuted by a reliable source. 3. Can observations verify the Yes. For the purposes of supporting the appropriate designation of ERA, this is a key data gap and it is the Open Water and/or reasonable to expect an initial survey to Developed habitat types or verify, qualify, or revise the habitat revise the habitat designation designation and/or species lists within in areas immediately PRIs 1 through 12 sufficient to support surrounding the operating the ERA. facility?

ERM 12 US MAGNESIUM/0132320 – JANUARY 2013

Hence, the primary goal of the field effort is to survey and document the range of biotic conditions within areas designated by SWReGAP as Open Water or Developed habitat types in the areas immediately surrounding the operating facility (PRIs 1 through 12). A secondary goal of the field effort is to record field observations that may help identify the types of receptors using habitats in areas immediately surrounding the operating facility. These observations include signs such as tracks, scat, burrows, and nests, as well as direct sighting of various types of biotic receptors that may be present at the time the field effort is implemented. Information from the field survey will be used to: 1. Confirm the designation of the Open Water and Developed habitat types; 2. Modify the definition of the Open Water and/or Developed habitat types to be more appropriate for observed biotic conditions; or 3. Assign one or more appropriate habitat types to areas immediately surrounding the operating facility.

3.2.2 Mapping

The goal of the mapping effort is to map habitats within the RI/FS Study Area and list biotic receptors using these habitats. SWReGAP habitat maps and WHRs will be the primary source for the buffer areas (PRIs 13 through 16). Maps and species lists for areas immediately surrounding the operating facility (PRIs 1 through 12) will be based on an amalgamation of SWReGAP habitat maps/WHRs, observations from the field survey, and recent aerial photographs.

3.3 STEP 3: IDENTIFY INFORMATIONAL INPUTS

To meet the goal of identifying habitats and biotic receptors within the RI/FS Study Area, informational inputs include:  SWReGAP habitat maps and habitat-specific species lists;  Historical aerial photographs;  Species lists from past studies; and  Field observations for areas designated as Developed habitat type in areas immediately surrounding the operating facility.

ERM 13 US MAGNESIUM/0132320 – JANUARY 2013

3.4 STEP 4: DEFINE THE BOUNDARIES

The spatial boundary for biotic information is the RI/FS Study Area. The temporal boundary for biotic information is year-round—i.e., species lists will include both year-round resident and seasonal migratory species associated with each habitat within the RI/FS Study Area.

3.5 STEP 5: DEVELOP THE ANALYTICAL APPROACH

Maps and species lists will be used to identify the types/categories of receptors that are observed/expected within the RI/FS Study Area that will be evaluated as part of the ERA.

3.6 STEP 6: SPECIFY PERFORMANCE CRITERIA

There are no specific quantitative acceptance criteria for habitat occurrence surveys. However, the data collected must be sufficient to support the development of reliable habitat maps that can be used to support the selection of ecological exposure areas and receptors.

3.7 STEP 7: DEVELOP THE PLAN FOR OBTAINING DATA

The plan for obtaining data is described in subsequent sections of this work plan. Products of the EcoSurvey/Map will include habitat maps and types of receptors using each habitat type within the entire RI/FS Study Area (Section 7).

ERM 14 US MAGNESIUM/0132320 – JANUARY 2013

4.0 FIELD SURVEY DESIGN

The field survey of the EcoSurvey/Map is intended to characterize the range of biotic conditions within the Developed habitat type assigned to upland land cover for PRIs 1 through 12. Key design features of the field survey are as follows:  The Field Survey Team will consist of:  a qualified plant biologist who will be the Field Survey Team leader and will survey and record habitats and plants using a modified relevé method; and  a qualified wildlife biologist who will record opportunistic, incidental observations and/or signs of terrestrial invertebrates and wildlife.  The habitat and wildlife survey field effort will be conducted over 5 consecutive days, preferably in the months of May, June, or July.  A ½-day reconnaissance of the Developed habitat in areas immediately surrounding the operating facility that will be conducted to familiarize the Field Survey Team and finalize field survey locations.  Twenty-four (24) locations will be surveyed for habitat and wildlife. The number of locations was deemed sufficient for this effort as it provided sample locations across the range of conditions at PRIs 1 through 12 within a reasonable level of effort.  Both habitat and wildlife field surveys will be conducted concurrently and at the same locations.

For PRIs 13 through 16, SWReGAP maps and habitat-specific species lists will be used to identify the types of receptors that will be evaluated as part of the ERA.

4.1 MANDATORY CONTRACTOR SAFETY ORIENTATION

Prior to field efforts, the two-person Field Survey Team will complete the mandatory contractor safety orientation at the US Mag facility to review site hazards, potential safety-related issues, and emergency protocols while conducting the field effort. Both Field Survey Team members will hold current Occupational Safety and Health Administration Hazardous Waste Operations and Emergency Response certification and the required

ERM 15 US MAGNESIUM/0132320 – JANUARY 2013

respiratory protection certification and clearance required by the Site- Specific Health and Safety Plan (ERM 2012a).

4.2 FIELD SURVEY LOCATIONS

The number and location of proposed field survey locations are considered to provide sufficient coverage (within the survey period) to characterize the range of biotic conditions within the Developed habitat type in areas immediately surrounding the operating facility. Proposed field survey locations are listed in Table 4-1 and shown on Figure 4-1. Because several proposed field survey locations are near or adjacent to Open Water habitat, any direct observations of invertebrates and/or wildlife using this habitat type during the survey period will be noted. Final field survey locations will be identified and positioned based on professional judgment of representativeness of habitat conditions, accessibility, and safety considerations.

Following the mandatory contractor safety orientation, the Field Survey Team will conduct a ½-day field reconnaissance to familiarize themselves with PRIs 1 through 12 and to appraise proposed field survey locations. Following the field reconnaissance, final field survey locations will be discussed with the USEPA Region 8 (either with accompanying USEPA staff in the field or via a teleconference call) prior to performing the survey, to ensure consensus on the field effort. Should it be necessary to conduct a teleconference call to finalize survey locations, the time and date of this call will be established prior to the field survey.

4.2.1 Allocation and Rationale of Survey Locations

SWReGAP classified terrestrial land cover in areas immediately surrounding the operating facility as Developed (low- or high-intensity). A single habitat categorization may be an oversimplification for the purposes of supporting the ERA. From a recent site visit and review of aerial photographs, it appears that the Developed habitat type may categorize land cover ranging from barren ground to greasewood flat habitat. Observations at the 24 survey locations in areas immediately surrounding the operating facility will be used to (Table 4-1):  Verify SWReGAP’s designation of the Developed habitat type;  Modify the Developed habitat type to be more appropriate for biotic conditions observed in the field; or

ERM 16 US MAGNESIUM/0132320 – JANUARY 2013

 Assign a new SWReGAP habitat type where appropriate.

Field observations at six of the 24 survey locations situated near or adjacent to Open Water habitat in areas immediately surrounding the operating facility will be used to (Table 4-1):  Verify SWReGAP’s designation of the Open Water habitat type; and  Qualify the Open Water habitat type to be more appropriate for biotic conditions observed at these industrial impoundments.

4.2.2 Proposed General Position of Survey Locations

Based on aerial photographs and a recent site visit, the general positions of proposed representative survey locations provide coverage across the Developed habitat type in PRIs 1 through 12 and are mapped on Figures 4-1 through 4-5. Figure 4-1 is intended to provide a visualization of coverage and Figures 4-2 through 4-5 provide a closer view. Note that PRI boundaries are provided on maps for perspective.

Final survey locations will be determined in the field by qualified plant and wildlife biologists based on representativeness, accessibility, and safety considerations.

4.3 TIMING AND DURATION OF FIELD SURVEY

The area around the GSL is most biologically active from the late spring, after snowmelt, through the early fall. The species for which phenology information was available indicate that the largest numbers of flowering plants can be found in May, June, July, and August (Table 4-2).

Migratory waterbirds are active in the GSL area throughout the late spring and summer. The birds for which migratory information was available have been placed in a matrix (Table 4-3). This matrix indicates that the majority of the bird population can be found around the GSL between April and September.

The timing of the field survey will consider both ecological and programmatic constraints. Based on the above information, proposed timing of the field survey will be over 5 consecutive days in May, June, or July 2013. Familiarity of habitat types and conditions in the field will dictate length of time spent at any one survey location; however, in general, each survey location will be surveyed for approximately

ERM 17 US MAGNESIUM/0132320 – JANUARY 2013

60 minutes by both a qualified plant biologist and wildlife biologist. Accounting for travel between survey locations, it is anticipated that six survey locations can be inspected per day (assuming a 10-hour day). Note that there are several tasks that may be conducted by either the plant or wildlife biologist to optimize time spent at each location (Section 5).

ERM 18 US MAGNESIUM/0132320 – JANUARY 2013

5.0 FIELD SURVEY METHODS

Field observations of RI/FS Study Area-specific habitats and wildlife are intended to ground-truth preliminary habitat maps and WHRs. There are several tasks that may be conducted by either the plant or wildlife biologist, to optimize time spent at each location, including, but not limited to:  Recording the survey location using a portable global positioning system (GPS) unit;  Noting physical attributes (e.g., topography, land form); and  Photo-documenting the survey location.

Preliminary habitat maps and species lists will be used to provide reference and aid field ground-truthing efforts that will be conducted during the field survey. Methods for surveying habitat and wildlife are described below.

5.1 HABITAT SURVEY

At each survey location, a qualified biologist will:  Record the survey location using a portable GPS unit;  Note physical attributes (e.g., slope, aspect, land form); and  Identify habitat type(s) and visually characterize extent.

At each survey location, one or more smaller areas (or plots) will be established within an area of homogenous habitat type. Plot selection will be performed in a deliberate, biased manner. Plots will be selected to be representative of the habitat type of interest at that particular survey location. Hence, the plot should capture common species composition and structural conditions for that particular habitat type. If there are several habitat types at a particular survey location, a minimum of one plot per habitat type would be surveyed.

To reliably, efficiently, and semi-quantitatively assess the vegetative cover, a modified relevé method will be employed.

ERM 19 US MAGNESIUM/0132320 – JANUARY 2013

5.1.1 Modified Relevé Method

The relevé method relies on visual estimates of plant cover rather than on counts of the “hits” of a particular species along a transect line or precise measure of cover/biomass by planimetric or weighing techniques. Because it employs visual estimates instead of empirical measures, it is generally faster than other survey techniques. Thus, the relevé approach is particularly useful when observers are trying to quickly classify the range of diversity of plant cover over large units of land. A number of reputable organizations employ this approach, including the United States Forest Service and California Native Plant Society.

For each plot, the following approach will be taken: 1. Select a representative plot within a habitat type that has compositional and structural integrity. 2. Record the plot location using a portable GPS unit. 3. Document the plot with descriptors that include: a. General information describing its location, size, and shape within the habitat type; b. Surface cover (barren to 100 percent vegetation) and soil information; c. Vegetation structure such as canopy layers, phenology, and habitat classification (e.g., forest, wetland, wash); d. Species composition, dominant plants, and qualitative estimates of percent cover; e. Level of disturbance, scaled from 1 (minimal) to 3 (high); and f. Descriptors including successional stage and notable landmarks. 4. Photo-document the plot (from a minimum of two different aspects). 5. Document field activities with handwritten notes in a field notebook and hardcopy field maps.

A more detailed description of this approach is provided in Appendix B.

5.2 WILDLIFE SURVEY

Wildlife species habitat relationships for the Open Water and Developed habitat type will be ground-truthed concurrently with the habitat survey.

ERM 20 US MAGNESIUM/0132320 – JANUARY 2013

To the extent practical, direct observation or signs of wildlife will be used to annotate the presence/absence of wildlife at the time of the survey. Given the observed condition of the habitat and/or other signs of wildlife, the wildlife biologist may also infer whether a given species may be expected to occur in the habitat. Biota of interest for this survey includes:  Invertebrates;  Amphibians;  Reptiles;  Birds; and  Mammals.

Although no seining of surface water will be performed, direct observations of aquatic invertebrates will be conducted if water is close to survey locations.

Wildlife survey locations will be co-located and concurrently surveyed with the habitat survey. At each survey location, a qualified wildlife biologist will:  Record the survey location using a portable GPS unit;  Note physical attributes (e.g., topography, land form);  Document direct observations of wildlife (including eggs, cysts);  Document evidence (signs) of wildlife use in the area (e.g., burrows, scat);  Evaluate general habitat suitability and note whether particular species groups are likely to be absent/occur;  Photo-document conspicuous characteristics and/or signs to support a qualitative assessment of use; and  Document field activities with handwritten notes in a field notebook and hardcopy field maps.

With regard to direct observations of animals, the qualified wildlife biologist will note:  Species to lowest taxon possible;  Estimated numbers;  Estimated life-stage (e.g., adult, juvenile);

ERM 21 US MAGNESIUM/0132320 – JANUARY 2013

 Movement patterns (if observed); and  Activity (e.g., drinking, feeding, nesting, denning).

With regard to signs, the qualified wildlife biologist will note:  Brine fly puparial casts;  Footprints;  Presence of scat, shells, skins, fur, bones, feathers, or other biotic debris;  Browsing/chewing of vegetation;  Burrows and other evidence of nesting; and  Animal calls or sounds.

ERM 22 US MAGNESIUM/0132320 – JANUARY 2013

6.0 MAPPING METHODS

Initial analysis of the SWReGAP habitat map was used to identify habitat types and wildlife species potentially using/occurring in PRIs 1 through 16 within the RI/FS Study Area. These preliminary maps will be revised based on the findings of habitat and wildlife surveys.

All GPS data collected in the field will be incorporated into the GIS database for the project. GPS-based data will aid in characterizing RI/FS Study Area-specific conditions of habitats and noting/verifying species observed/expected in these habitats. GPS data will be recorded in the original geographic coordinate system of the GPS unit. All mapping and map products will be projected using the designated project coordinate system (Utah State Plane, Central Zone, NAD83, US Feet) as described in the Data Management Plan (ERM 2012b).

Finished report maps will be generated from the combination of desktop and field data for presentation and review purposes.

All maps and GIS data will be checked for:  Projection consistency;  Measurement units consistency;  Topology verification (i.e., no overlapping areas, gaps between areas, or duplicate features); and  Cartographic consistencies across the finished map atlas.

6.1 BASE MAPS

The following base maps were utilized in the initial desktop analysis:  Land cover maps provided by SWReGAP, which provides a seamless habitat map for Utah and neighboring states;  Soils data/maps provided by the USDA NRCS;  Wetland location data/maps provided by the National Wetlands Inventory;  Digital aerial ortho-photographs provided by the Farm Service Agency’s National Aerial Imagery Program; and  USGS 1:24,000 topographic maps provided by Utah SGID.

ERM 23 US MAGNESIUM/0132320 – JANUARY 2013

These base maps will form the basis for continued analysis and visualization of data and will aid in the modification of captured/displaced RI/FS Study Area-specific data.

6.2 HABITATS

National Aerial Imagery Program aerials from 2011 suggest changes to habitat maps since the SWReGAP habitat mapping took place. Habitat mapping updates will use a combined field and desktop effort. Field crews will ground-truth and verify changes to habitat areas utilizing GPS systems, field maps, and field notes. Specifically, the results of the field survey will be compared to the plant species lists provided for the Developed habitat type, as well as other SWReGAP habitat types should re- assignment of habitat type be appropriate. Habitat maps and plant species lists will be updated/supplemented to reflect the biological conditions observed within the Developed habitat type for areas immediately surrounding the operating facility, in particular:  Surface cover;  Vegetation structure;  Common plant species and percent cover; and  Level of disturbance.

Field observations, combined with aerial photo interpretation, will allow for accurate modifications to the polygon feature class boundaries, resulting in descriptions that reflect more correctly the current conditions as they pertain to surface cover, vegetation structure, or levels of disturbance. Note that the field survey results will not be used to re-map or re-delineate the habitat types within the buffer areas (PRIs 13 through 16) of the RI/FS Study Area. However, re-mapping and/or re-designation of habitat type may be performed based on observed obvious biological changes (and as confirmed by field observations) within the Developed habitat type for areas immediately surrounding the operating facility (PRIs 1 through 12).

Photo points recorded with GPS converted to feature class point files on maps will display the locations of where the photos were taken and be labeled with the corresponding photo or folder. All photographs will be a part of the Electronic Data Package deliverable (Section 7.1).

ERM 24 US MAGNESIUM/0132320 – JANUARY 2013

All changes and adjustments to the habitat spatial data will be included in the final GIS Geodatabase deliverable in the form of new feature class files. All associated maps and figures will contain updates with the newly revised data reflecting the changes made with GIS.

6.3 WILDLIFE-HABITAT RELATIONSHIPS

Wildlife habitat relationships will be examined in more detail following the field survey effort. Field data information from the wildlife survey will verify whether a given species was observed, or will be expected to occur in a particular habitat type.

Wildlife survey results will not be used to re-map fauna associated with particular habitat types within the buffer areas of the RI/FS Study Area. However, field observations, combined with SWReGAP WHRs, will be used to supplement and/or appropriately qualify species likely to be associated with the Developed habitat type or a re-classified habitat type for areas immediately surrounding the operating facility.

GIS analysis of wildlife presence in relation to habitat types will rely primarily on overlaying data layers and extracting corresponding data as it relates between each dataset. GIS will use the field observations—in the form of GPS location data, field notes, and photographs of wildlife presence in the project location areas—to create feature class files to record their presence. Feature class point files will record direct observations of wildlife (e.g., overflying birds) and indirect observations of wildlife (e.g., signs, calls). These feature classes will be included in the final GIS Geodatabase.

All maps and figures will contain the updated features, including the new wildlife information gathered in the field.

ERM 25 US MAGNESIUM/0132320 – JANUARY 2013

7.0 ECOSURVEY/MAP DOCUMENTATION

The EcoSurvey/Map results will be presented in the following:  Electronic Data Package; and  Habitat and Wildlife Survey and Mapping Report.

7.1 ELECTRONIC DATA PACKAGE

An Electronic Data Package will be provided in DVD format and will consist of: 1. An ArcGIS Geodatabase containing feature classes (i.e., shapefiles) for the following:  PRI area;  Habitat types;  Sampling locations;  Photo point locations;  Species observation locations; and  Species sign observation locations.

Any other relevant spatial data either created remotely by desktop analysis or captured in the field will be included in the ArcGIS Geodatabase. These feature classes will allow potential users to view data within GIS software, aid with future analysis, verify the accuracy of the information provided, or create maps and illustrations of the study for presentations or reports.

Feature classes will be delivered in point, line, or polygon format, as determined most appropriate for the data source and type. 2. Complete species lists, in Excel format, with indicators for sensitive species and species actually observed within the RI/FS Study Area. 3. All field notes and accompanying photographs of the existing or modified habitats, species sightings, and signs, and any other documentation or observations from the field effort.

4. Map atlas in Adobe PDF format illustrating field observation data, wildlife species distribution, SWReGAP land cover data, and relevant base map data such as aerial photographs, topography, soils, and PRI boundaries.

7.2 HABITAT AND WILDLIFE SURVEY AND MAPPING REPORT

The Habitat and Wildlife Survey and Mapping Report will present the findings of the field survey and updated maps and species lists for habitat types within the RI/FS Study Area—in particular, for the area immediately surrounding the operating facility. This report will also include photographs and field notes compiled by the plant and wildlife biologists. A draft report will be provided to oversight agencies for their review and comments. Responses to comments and a final report will be prepared and will provide the basis for the ERA.

1 of 1 Table 2-3. Dominant Habitat Type Descriptions

Habitat Type Description Open Water All areas of open water, generally with less than 25% cover of vegetation or soil. Inter-Mountain Basins This ecological system occurs throughout much of the western U.S. in Greasewood Flat Intermountain basins and extends onto the western Great Plains. It typically occurs near drainages on stream terraces and flats or may form rings around playas. Sites typically have saline soils, a shallow water table, and flood intermittently, but remain dry for most growing seasons. This system usually occurs as a mosaic of multiple communities, with open to moderately dense shrublands dominated or co-dominated by Sarcobatus vermiculatus. Atriplex canescens, Atriplex confertifolia, or Krascheninnikovia lanata may be present to co- dominant. Occurrences are often surrounded by mixed salt desert scrub. The herbaceous layer, if present, is usually dominated by graminoids. There may be inclusions of Sporobolus airoides, Distichlis spicata (where water remains ponded the longest), or Eleocharis palustris herbaceous types. Inter-Mountain Basins This ecological system is composed of barren and sparsely vegetated playas Playa (generally <10% plant cover) found in the Intermountain western U.S. Salt crusts are common throughout, with small saltgrass beds in depressions and sparse shrubs around the margins. These systems are intermittently flooded. The water is prevented from percolating through the soil by an impermeable soil sub-horizon and is left to evaporate. Soil salinity varies greatly with soil moisture and greatly affects species composition. Characteristic species may include Allenrolfea occidentalis, Sarcobatus vermiculatus, Grayia spinosa, Puccinellia lemmonii, Leymus cinereus, Distichlis spicata, and/or Atriplex spp. Invasive Annual Avena spp., Bromus spp., Schismus spp. Grassland Developed Includes areas with a mixture of some construction materials, but mostly (Low-Intensity) vegetation in the form of lawn grasses. Impervious surfaces account for less than 20 percent of total cover. These areas most commonly include large-lot single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes. Developed (Low-Intensity): Includes areas with a mixture of constructed materials and vegetation. Impervious surfaces account for 20-49 percent of total cover. These areas most commonly include single-family housing units. Developed IncludesDRAFT areas with a mixture of constructed materials and vegetation. (High-Intensity) Impervious surface accounts for 50-79 percent of the total cover. These areas most commonly include single-family housing units. Developed (High- Intensity): Includes highly developed areas where people reside or work in high numbers. Examples include apartment complexes, row houses and commercial/industrial. Impervious surfaces account for 80 to 100 percent of the total cover.

1 of 2 Habitat Type Description Great Basin Pinyon- This ecological system occurs on dry mountain ranges of the Great Basin Juniper Woodland region and eastern foothills of the Sierra Nevada. It is typically found at lower elevations ranging from 1600-2600 m. These woodlands occur on warm, dry sites on mountain slopes, mesas, plateaus, and ridges. Severe climatic events occurring during the growing season, such as frosts and drought, are thought to limit the distribution of pinyon-juniper woodlands to relatively narrow altitudinal belts on mountainsides. Woodlands dominated by a mix of Pinus monophylla and Ecological Systems Juniperus osteosperma, pure or nearly pure occurrences of Pinus monophylla, or woodlands dominated solely by Juniperus osteosperma comprise this system. Cercocarpus ledifolius is a common associate. Understory layers are variable. Associated species include shrubs such as Arctostaphylos patula, Artemisia arbuscula, Artemisia nova, Artemisia tridentata, Cercocarpus ledifolius, Cercocarpus intricatus, Coleogyne ramosissima, Quercus gambelii, Quercus turbinella, and bunch grasses Hesperostipa comata, Festuca idahoensis, Pseudoroegneria spicata, Leymus cinereus (= Elymus cinereus), and Poa fendleriana. Inter-Mountain Basins This widespread ecological system occurs throughout the Intermountain Semi-Desert Grassland western U.S. on dry plains and mesas, at approximately 1450 to 2320 m (4750- 7610 feet) in elevation. These grasslands occur in lowland and upland areas and may occupy swales, playas, mesa tops, plateau parks, alluvial flats, and plains, but sites are typically xeric. Substrates are often well-drained sandy- or loamy-textured soils derived from sedimentary parent materials, but are quite variable and may include fine-textured soils derived from igneous and metamorphic rocks. When they occur near foothills grasslands they will be at lower elevations. The dominant perennial bunch grasses and shrubs within this system are all very drought-resistant plants. These grasslands are typically dominated or co-dominated by Achnatherum hymenoides, Aristida spp., Bouteloua gracilis, Hesperostipa comata, Muhlenbergia torreyana, or Pleuraphis jamesii, and may include scattered shrubs and dwarf-shrubs of species of Artemisia, Atriplex, Coleogyne, Ephedra, Gutierrezia, or Krascheninnikovia lanata.

1.0 SCOPE AND APPLICABILITY

This Standard Operating Procedure (SOP) describes methods for conducting habitat and wildlife surveys at the US Magnesium Site in Rowley, Utah. This SOP will be used to conduct the field survey portion of the EcoSurvey/Map effort for areas designated as Developed habitat type in areas immediately surrounding the operating facility.

2.0 OVERVIEW OF METHOD

The purpose of this SOP is to describe the approach for surveying habitats, vegetation, and wildlife at the US Magnesium Site. These surveys are designed to collect physical and biological information to verify and, if needed, to modify or re-assign habitat type designations to the Developed habitat type assigned to areas immediately surrounding the operating facility. In addition, field observations will be used to complement/ supplement species lists associated with these habitat types. The field surveys will assist the preparation/update of habitat maps and the electronic species databases to reflect on-the-ground conditions.

A modified relevé technique is used to ground-truth existing habitat maps. The method can be broken into three main parts:

 Documentation of the physical features of each survey location;  Documentation of the vegetation at each survey location;  Documentation of the wildlife at each survey location.

Existing habitat maps and species lists will be used to provide reference materials and aid ground-truthing efforts that will be conducted during the field survey. The number, allocation, and location of survey locations are described in the work plan and are not discussed further herein. A general overview of methods for surveying each location is provided below—further details are provided in Section 6.

2.1 Description of Survey Locations

In general, habitats are too large to realistically sample in their entirety. At each representative survey location, a smaller area (or plot) will be established within an area of homogenous habitat type (or stand) to take a representative “survey” of that habitat. Selection of a plot will performed in a deliberate, biased manner. Plots will be selected to be representative of the habitat type of interest at that particular survey location. Hence, the plot should capture common species composition and structural conditions for that particular habitat type. If there are several habitat types at a particular survey location, a minimum of one plot per habitat type would be surveyed.

The plot will be documented with the following descriptors:

 General description (i.e., location, size, shape, elevation, slope, aspect)  Habitat type  Level of disturbance  Hydrology  Successional stage  Surface cover  Photo documentation

Additional details on these methods can be found in Section 6.2.

2.2 Vegetation Survey

To reliably, efficiently, and semi-quantitatively assess the vegetative cover, a modified relevé method will be employed. The relevé method relies on visual estimates of plant cover rather than on counts of the “hits” of a particular species along a transect line or precise measure of cover/biomass by planimetric or weighing techniques. Because it employs visual estimates instead of empirical measures, it is generally faster than other survey techniques. Thus, the relevé approach is particularly useful when observers are trying to quickly classify the range of diversity of plant cover over large units of land. A number of reputable organizations employ this approach, including the U.S. Forest Service and California Native Plant Society.

The relevé method used here has a number of key components:

 Generation of a species list  Assessment of the vegetation structure  Estimates of percent cover for each taxonomic group  Estimates of cover of dominant vegetation types  Notes on observable vegetative stress  Additional remarks on representativeness of habitat

Additional details on these methods can be found in Section 6.3.

2.3 Wildlife Survey

Information from the wildlife survey will be used to verify/document (through direct observations or signs) the presence of wildlife. Given the observed condition of the habitat and/or other signs of wildlife, the wildlife biologist may also infer whether a given species may be expected to occur in the habitat. Biota of interest for this survey includes:

 Invertebrates  Birds  Amphibians  Mammals  Reptiles

At each survey location, a qualified wildlife biologist will:  Document direct observations of wildlife (including eggs, cysts);  Document evidence (signs) of wildlife use in the area;  Evaluate general habitat suitability and note whether particular species groups are likely to be absent/occur;  Photograph conspicuous characteristics and/or signs to document use by wildlife; and  Document field activities with handwritten notes in a field notebook and hardcopy field maps. Additional details for these methods can be found in Section 6.4.

3.0 DEFINITIONS

Bioturbation The reworking of soils and sediments by animals or plants, particularly from burrowing and other similar activities Macrotophography Large topographic features such as rivers, mountains, and cliffs. Microtopography Small topographic features such as boulders, mounds, and small basins Plot A representative sampling area within a given habitat type Relevé a list of plants within a delimited plot of vegetation, with information on species cover and other abiotic features of the plot Stand A stand is the basic physical unit of vegetation in a landscape. Although it has no set size, it can be characterized by its compositional and structural integrity. Stands have relatively uniform species composition and discernible boundaries Surface Cover Surface cover refers to anything covering the ground including rocks, bare soil, dead vegetation, and live plants Vegetation Trend The successional stage and direction of the vegetation. The vegetation trend may be growing /expanding or senescing/shrinking.

Definitions for survey categories and criteria are provided throughout this SOP.

4.0 HEALTH AND SAFETY

All sampling activities undertaken within the RI/FS Study Area must be completed under an approved, site-specific Health and Safety Plan (HASP). The HASP identifies the hazards, personal protective equipment, monitoring, and emergency procedures for conducting work within the RI/FS Study Area. Samplers and support personnel must acknowledge their review of the HASP prior to performing work within the RI/FS Study Area.

5.0 PERSONNEL QUALIFICATIONS

Personnel performing the field survey must have current 40-hour OSHA Hazardous Waste Operations and Emergency Response (HAZWOPER) certification. Respiratory protection and other site-specific health and safety training requirements are described in the HASP.

6.0 PROCEDURES

6.1 Equipment checklist

Item Required Recommended Digital Camera X Hand-held GPS unit X Measuring tape X Plant sample collection envelopes X Species lists and data sheets X Binoculars X Area maps and PRI designations X Safety documentation (e.g., HASP) X Personal Protective Equipment X SWReGAP habitat descriptions X Species identification books X Flagging or survey tape X Hand-held clippers X Trowel X Drinking water X

6.2 Plot Selection

A stand is the basic physical unit of vegetation in a landscape. Although it has no set size, it can be characterized by its compositional and structural integrity. Stands have relatively uniform species composition and discernible boundaries. Stands should be representative of the area designated as that habitat type on the map. Once a stand is identified, the area to be surveyed must be narrowed to a reasonable size since most stands are too large to realistically sample in their entirety.

To effectively capture information, a smaller area (or plot) is designated as the area within a stand in which data are collected. Selection of a plot is done in a deliberate, biased way. Plots will be selected to be representative of the habitat in which it is found. If present, repeated variations in the landscape (e.g., dunes) should be captured within the designated plot. The plot should capture structural conditions and common

species composition. All of the plot information found in the following sections can be entered in the relevé worksheet in Attachment 1.

Plots can vary in size and shape depending on the dominant species, their spacing, topography, and landscape features. A minimal area to sample is defined by a plateau1 in the species-area relationship; that is, the size in which increasing plot size will not substantially increase the number of species found in the plot. Recommended plot sizes are listed on Table 6-1, but these are simply suggestions. Actual plot sizes and shapes will depend on the landscape features particular to the survey location.

Table 6-1 Suggested Plot Sizes Community Type Plot Size (m2) Herbaceous 10-100 Shrubland 100 Forest and woodlands 100 Open desert 10-100

The shape of a plot should reflect the landscape. For example, when sampling a ditch, the plot should be elongated to reflect the linear nature of that habitat. For other communities such as grasslands, a square or circular plot may be more appropriate. The plant biologist will choose the plot shape that best captures the habitat’s characteristics.

Ideally, the boundaries of a plot would be delineated in some way (e.g., flagging, survey tape); however, the time constraints of this survey may necessitate “eyeballing” the boundaries and simply noting prominent features that mark the edges of the plot. The surveyor should walk the boundary of the plot to record the global positioning system (GPS) coordinates of the plot boundaries.

6.2.1 General Descriptive Information

General descriptive information listed on Table 6-2 should be recorded for all plots.

Table 6-2 Overview of General Descriptive Information Information Type Descriptor Surveyor Plot number Assigned in field or office prior to sampling. PRI number The PRI where the plot is found Field map number and field The corresponding field map and notebook numbers

1 Also known as the “point of diminishing return.”

Information Type Descriptor notebook page number that are annotated for this plot Date Date of sampling. Surveyor Name of individuals assisting. Circle name of recorder. Landowner Note if data is available County All sampling should occur within Tooele County GPS readings Record the latitude and longitude. Indicate which part of the plot corresponds to the GPS reading. Generally, GPS readings should be taken from the northwest corner if the plot is rectangular or the center if it is circular. Plot shape Indicate shape as square, rectangle, circle, or entire stand. Plot size Length of rectangle edges, circle radius, or size of entire stand. Elevation Estimated from GPS readings Slope Estimated in degrees. Aspect Estimated degrees from true north. Macrotopography Estimated large-scale topographic position of the relevé. This is the general position of the sample along major topographic features of the area. Microtopography Estimated local relieve of the relevé. Choose the shape that mimics the lay of the ground along minor topographic features of the area actually within the sample. Plot location Boxes should be checked to indicate that the plot is far, moderately far, close to a communal boundary or cotonal Other polygons of similar Yes/No if applicable. Other areas within view that type appear to have similar vegetation composition. Mark on topo maps if possible. Plot description Provide a concise, but careful, description that makes locating and/or revisiting the vegetation stand and plots possible; give landmarks and directions.

6.2.2 Habitat Type

SWReGAP information has been used to identify different habitats within the RI/FS Study Area. A key objective of the field survey is to verify and document these habitat designations. Accordingly, careful notes will be taken to indicate the habitat type and any deviations from the SWReGAP designation (Table 6-3).

Table 6-3 Overview of Habitat Type Information Information Type Descriptor Mapped SWReGAP Habitat type Name habitat according to SWReGAP maps. SWReGAP Habitat type Name habitat according to visual observations and available habitat descriptors. Representative A yes/no qualifier for whether the sampling area and adjacent boundaries is representative of the greater area designated as the habitat type by SWReGAP. If they are not, describe the differences and provide relevant edits to the map.

6.2.3 Level of Disturbance

The level of disturbance is typically poorly described from desktop exercises alone. For that reason, describing the level of disturbance from field observations is crucial. Where possible, obvious signs of disturbance including type (e.g., fire, landslides, drought, flood, pest outbreak) and year should be described. Additional notes should be made on the nature and extent of land use such as grazing, timber harvest, or mining. Previous or current industrial uses should also be noted here. Specific disturbance information to be collected is described in Table 6-4.

Table 6-4 Overview of Disturbance Information Information Type Descriptor Level of disturbance Enter code for the existing level of disturbance of the plant community. Characterize on a scale with undisturbed (1), minimally disturbed (2), and substantially disturbed (3). Source of disturbance Note the source of the disturbance as anthropogenic in nature (e.g., development or industrial) or from natural processes (e.g., drought, fire) History of the habitat Describe the history of the habitat including type and year of disturbance (e.g., fire, landslides, drought, flood, or pest outbreak) if known. Describe the disturbance and location of disturbance within and around plot.

6.2.4 Hydrology

Notes on hydrology as described on Table 6-5 should be recorded for all plots.

Table 6-5 Overview of Hydrology Information Information Type Descriptor Aquatic or terrestrial Indicate whether the plot supports aquatic (e.g., ditch, wetland, playa, lake) or terrestrial habitat. Saturation Indicate the frequency of saturation (never, intermittent, or perennial) Remarks For those areas that are wetlands, note the origin if the water source if known.

6.2.5 Successional Stage

The successional stage of the habitat can be noted based on the life stage of the vegetation present and/or the disturbance history. Successional stage should be based on the regenerating species and relationship to the surrounding vegetation, characterize the stand as increasing or expanding (I), stable (S), decreasing (D), fluctuating (F), or unknown (U).

6.2.6 Surface Cover

Unvegetated surface cover may comprise a large proportion of the overall cover at the survey location. The relevé method allows for the rapid semi-quantification of this cover, which may aid to corroborate the habitat classification. Specifically, note observations described on Table 6-6.

Table 6-6 Overview of Surface Cover and Soil Information Information Type Descriptor Surface cover Estimate the percent cover class of the coarse cover types in the plot. Total cover should add up to 100 percent. Categories of cover can include:  Fines (sand, silt and soil < 2 millimeters in diameter);  Gravel (rounded and angular fragments (0.2-7.5 centimeters (cm) in diameter);  Cobble (rounded and angular fragments 7.5-25 cm in diameter);  Stone (rounded and angular fragments 25-60 cm in diameter);  Boulder (rounded and angular fragments > 60 cm in diameter);

Information Type Descriptor  Bedrock (continuous, exposed, non-transported rock);  Litter (extent of undecomposed litter on surface of plot including logs, branches, twigs, needles and leaves); and  Living stems (in cross section) of living vascular plants at the ground surface. Percent Estimate of percent cover of ground disturbance by animals across the bioturbation entire plot surface. Soil Map Unit Record the soil map unit provided in the maps Remarks Note any relevant observations about the soil or surface cover at the survey location such as whether biotic crusts are present

6.2.7 Photo-Documentation

Each plot should be photo-documented for future reference. The photographer should stand in the center of the plot and note the GPS reading, as well as the starting photo number. The photographer should take the first photo from the north and rotate clockwise taking four photos in sequence (north, east, south, west). The camera should be maintained at the same orientation, zoom level, and distance from the ground for all four photos. Additional photos can be taken of important features, disturbance, species, or evidence of animal activity at the survey location.

6.3 Vegetation Survey

The vegetation survey will document plant species observed at each survey location. Common/dominant plants and plant associations are key in verifying or re-assigning habitat type. The following characteristics will be carefully documented:

 Species list  Assessment of vegetation structure  Percent cover  Stress

Each characteristic and the appropriate method for collecting the data are detailed in the following subsections. The field worksheet that should be used to complete the following sections is available in Attachment 2.

6.3.1 Species List

A list of common and distinguishing plant species should be created for each plot surveyed. The plant biologist should wander through the plot, recording all the species he/she finds and noting relevant observations about these species such as the layer of the habitat in which the species is found. Special attention should be paid to microhabitats within the plot that may harbor different species. In general, the list may be considered complete, when new taxa are infrequently noted.

6.3.2 Assessment of Vegetation Structure

Vegetation structure information will be coded for five layers (tree, shrubs/saplings, herb, non-vascular, and unvegetated/bar ground). The layer or stratum a species occupies is determined by life form. For example, a young tree that is shrub-sized may be considered an understory tree.

6.3.3 Percent Cover

A few methods are available for surveying plant cover without the use of direct measures. These techniques will be described here as a guide. The plant biologist may employ any technique or combination of techniques that he/she feels is most appropriate and accurate.

Method 1: Invisible point intercept transect. One approach to estimating cover would be to mentally draw a line through the plot. The surveyor would then walk her eye along the invisible line and record the species of interest intercepting the line at that point. This should be repeated at regular intervals along the invisible transect for 25, 50, or 100 points. From these “hits” along the transect line, percent cover can be easily calculated in the field for that species. This method should be repeated for each species of interest to calculate a relative abundance for all of the dominant species.

Method 2: Subdivision of sample plot into quadrants. The plot can be visually subdivided into a quarter to make it a more manageable size for percent cover survey. The approximate size of the subplot should be noted. In this subplot, the surveyor may estimate the average size of the dominant species (e.g., Pinyon pine may be 5 square meters or 2.2 meters (m) x 2.2 m). Then, those species are tallied for the subplot or quadrant. A simple multiplication of the number of species by the area estimate of a single individual will provide the cover of that species in the plot. Calculating that area as percentage will provide a percent cover for that subplot.

Method 3: Compress all the plants into a continuous cover in the corner of the plot. Another option for estimating percent cover is to mentally march all of the members of particular species into the corner of the plot and estimate the area they cover. Then, calculate that area as a percentage of the total plot area. This would be repeated with all of the abundant plant species in the plot.

Method 4: Process of elimination technique. This is a recommended technique for estimating cover in areas where there is more exposed ground than vegetation. First, the cover of exposed earth should be estimated. The remaining percentage, then, is vegetated cover. The vegetated percentage then should be allocated among the species found at the plot.

For all techniques of estimating percent cover, cover can be estimated not as exact percentages, but rather as cover classes (Table 6-7). These cover classes represent the variability in cover that one may find across the habitat.

Table 6-7 Overview of Cover Classes Cover Class Explanation 1 Taxon in that layer covers < 1% of the plot area 2 Taxon in that layer covers 1%-5% of the plot area 3a Taxon in that layer covers 6%-15% of the plot area 3b Taxon in that layer covers 16%-25% of the plot area 4 Taxon in that layer covers 26%-50% of the plot area 5 Taxon in that layer covers 51%-75% of the plot area 6 Taxon in that layer covers > 75% of the plot area

6.3.4 Overall Coverage of Dominant Vegetation Types

In addition to cover of individual taxa described above, total cover will be estimated for each vegetation layer (Table 6-8). This is doing using the same cover classes described above, but combines all taxa into a given category. These cover percentages should be absolute aerial cover, so totals should not exceed 100 percent, even if vegetation is overlapping. Plant overlapping within a cover type should be disregarded.

Table 6-8 Overview of Vegetation Cover Information Cover of Vegetation Explanation % Overstory/Trees Estimate should be made of the total aerial cover (i.e., canopy closure) of all living trees that are in the overstory. % Shrub/Sapling Estimate should be made of total aerial cover (canopy closure of all live shrub species.

Cover of Vegetation Explanation % Herb Estimate should be made of total aerial cover (canopy closure of all live herbaceous species. % Total vascular Estimate should be made of the total aerial cover of all plants vegetation.

6.3.5 Stress

Signs of vegetative stress may be used as one descriptor for the level of disturbance at a particular survey location. Specific signs of stress that can be noted including standing dead or recently felled vegetation, dying vegetation as indicated by sparse canopies, yellowing or spotted leaves, rust or insect outbreaks, galls, or necrosis.

6.3.6 Additional Remarks

For each species observed, the surveyor can note any additional relevant observations about the abundance, distribution, sociability, or phenology of that species. Specifically, it may be useful to note if large numbers are observed germinating, or in the seedling stage, whether fruiting or flowering is taking place, or whether the species was observed outside of the plot.

For those species that could not accurately be identified in the field, a small sample can be collected for keying out at a later time. The specimen number of these unknown samples should be recorded in the remarks section of the worksheet. List the numbers of unknown plant specimens, noting any information such as family or genus (if known), important characters, and whether or not there is adequate material for identification. Removal of plant samples is not recommended for those species that have only a few individuals or that may be rare.

Finally, the surveyor should describe the vegetation community within and adjacent to the plot. Note whether the vegetation community and boundaries are in general agreement with the mapped SWReGAP habitat type. If differences are noted, these should be described in detail.

6.4 Wildlife Survey

Ideally, wildlife surveys are conducted at dawn and dusk when animals are most likely to be active and visible. However, the time constraints for this field survey may make it infeasible to sample and optimal times for all locations. The time of the survey should be carefully noted on each datasheet. Although the majority of the survey should be conducted within the designated plot, the wildlife biologist may find that if he/she sits in a local high spot, that he/she may have a better vantage point for surveying the

wildlife. About half of the time dedicated to wildlife surveys at each survey location should be spent sitting with binoculars looking for direct observations of wildlife activity and the other half should be spent surveying the plot for signs of wildlife.

With regard to direct observations of animals, the qualified wildlife biologist will note:

 Species to lowest taxon possible;  Estimated numbers;  Estimated life-stage (e.g., adult, juvenile);  Movement patterns (if observed); and  Activity (e.g., drinking, feeding, nesting, denning).

With regard to signs, the qualified wildlife biologist will note:

 Brine fly pup Arial casts;  Footprints;  Presence of scat, shells, skins, fur, bones, feathers, or other biotic debris;  Browsing/chewing of vegetation;  Burrows and other evidence of nesting; and  Animal calls or sounds

All of these observations should be noted in the field worksheet in Attachment 3.

7.0 DATA RECORDS AND MANAGEMENT

All observations should be carefully documented in either a field map or on one of the data worksheets provided. Descriptions for each section of the data worksheets are outlined in Section 6.0. At a minimum, the following needs to be recorded at each survey location:

 Date and time of sampling  GPS coordinates of the survey area  Photos to document key features  Plot and stand information recorded in Attachment 1  Vegetation presence and abundance recorded in Attachment 2  Annotation of relevant landmarks and boundaries on maps  Any relevant deviations from the SOP, sampling and analysis plan, or work plan

8.0 QUALITY ASSURANCE/QUALITY CONTROL

Survey results are descriptive (i.e., estimates) in nature. No quantitative QA/QC protocols are proposed.

9.0 DEVIATIONS

These procedures apply to all related work conducted for the US Magnesium RI/FS, and the information in this SOP may be used by direct reference or incorporated into project-specific plans. Deviation from the SOP described herein must be brought to the attention of, and approved by, the ERM and EPA management team. Should situations occur in the field during a sampling event that require deviation from this SOP, the following procedure will be followed:

 The field team will notify the Project Managers of the field conditions and the proposed deviation from the SOP. The specific Project Managers to be notified are as identified in the project-specific planning document (e.g., SAP, Work Plan), or at a minimum will include the ERM and USEPA Project Managers for the US Magnesium RI/FS.

 The field team will obtain written approval for implementing the proposed deviation from the SOP.

 The deviations from this SOP will be documented.
