C. Identify which of the following areas of expertise your company can provide services to support this contract.

Tetra Tech has project managers and field staff based in Flagstaff, Phoenix, and Tucson and could readily mobilize from each of these locations depending on sampling site location and type of sampling needed.

o Stream Chemistry Sampling

i. A two-person field team with considerable knowledge and background in environmental science would follow the methods presented in the Standard Operating Procedures for Surface Water Quality Sampling prepared by the Surface Water Section of ADEQ in March 2018. The team would be comprised of staff experienced in conducting water quality surveys, collecting stream water samples, using multi-parameter probes, and measuring flow via a variety of methods. Each location would typically be sampled 4 times per year for metals, nutrients, inorganics, and E. coli. Work may also include sampling impaired waters or special studies. Some automated and ephemeral or intermittent stream sampling is anticipated. Field measurements would include dissolved oxygen, specific conductance, pH, temperature, and depth. Turbidity, free and total chlorine, and air temperature would also be assessed. Water chemistry samples would be collected for organic compounds; total, dissolved, and suspended organic carbon; inorganic constituents, nutrients, radiochemicals, and isotopes; and microorganisms. The analysis of dissolved metals would require filtration of the water sample prior to preserving the sample with nitric acid. Blank, duplicate, and split samples would be collected and a chain of custody recorded for quality assurance. Grab, Equal Width Increment, Modified EWI, or Equal Discharge Increment sampling would be used depending on stream depth and velocity.

ii. Senior Environmental Specialist Keith Pohs performed manual grab sampling for stream chemistry at a historic mine site along the Hassayampa River in the Bradshaw Mountains in 2018 and 2019 in response to a consent decree by ADEQ to address input of cadmium, copper, and zinc from the site. The waterbody was subject to a Total Maximum Daily Load. He is familiar with field metals sampling procedures including maintenance of chain-of-custody and sample preservation depending on the laboratory analytical techniques required. As part of this effort he also prepared a Sampling and Analysis Plan.

iii. Poland Walker Tunnel (ADEQ)

1. Big Bug Creek and Poland Walker Tunnel

a. Various strategic sampling locations were selected and sampled along Big Bug Creek upstream and downstream from the Poland Walker Tunnel inflow point to assess water quality changes and potential contamination impacts

iv. Gibson Mine (ADEQ)

1. Stream Sampling

a. Various strategic sampling locations were selected downstream from the Gibson Mine within the ephemeral creek to assess potential contamination impacts from the mine adit drainage o Lake Chemistry Sampling

i. A two-person field team with considerable knowledge and background in lake chemistry sampling and the biological sciences would follow the methods presented in the Standard Operating Procedures for Surface Water Quality Sampling prepared by the Surface Water Section of ADEQ in March 2018. The team would have expertise and experience conducting lake profile surveys, bathymetry surveys, collecting water samples from different depths using lake specific samplers, collecting sediment core samples, using multi-parameter probes, and collecting biological samples. The number of samples collected for a particular site will depend on whether or not the lake is stratified. To determine stratification, a multimeter probe would be extended to the bottom of the lake at the sample site. Water sample collection would include Secchi Depth, Beta Bottle, and Zooplankton sampling. Microcystin is a toxin produced by cyanobacteria and is harmful to humans and animals. Vertical tow, composite photic zone, and/or grab sampling would be used to sample for microcystin.

ii. Tetra Tech performed lake chemistry sampling at Rainbow Lake in Pinetop, AZ in support of the Highway 260 and Johnson WQARF project. Staff utilized a small boat to collect shallow and deep samples of lake water at various locations along the eastern edge of the lake, nearest the potential area of groundwater contamination. Tetra Tech utilized a Kemmerer-style sampling device to collect subsurface water samples at a specific depth, as well as a Secchi disk to determine sample depth and water clarity.

iii. Tetra Tech performed lake chemistry sampling at Naval Weapons Station Seal Beach, Detachment Norco, CA. Naval Weapons Station Seal Beach Detachment Norco is a 247-acre installation in northwest Riverside County, California, that supports the Naval Surface Warfare Center, Corona. Lake Norconian (Norco) is the primary natural resource feature at Detachment Norco. In 2000, the Lake Norconian Club Historic District was placed on the National Register of Historic Places. Tetra Tech was hired by Naval Facilities to develop a much-needed Integrated Lake and Landscape Management Plan to provide a comprehensive basis and framework for the management of the lake and the surroundings. The lake and ponds are important to migratory birds as evidenced by over 100 species of migratory birds that have been observed at Detachment Norco. Tetra Tech conducted a yearlong water quality monitoring program at Lake Norconian which included monthly sampling, one-time fish survey and sediment core sampling, continuous temperature and dissolved oxygen monitoring, as well as aquatic plant surveying and mapping. All data, both field and analytical results, were reviewed and evaluated by Tetra Tech who then incorporated the yearlong monitoring program results into a draft and final integrated lake and landscape management plan. As part of the management plan, Tetra Tech established water quality goals for total phosphorus, chlorophyll, dissolved oxygen, and salinity. Tetra Tech evaluated various lake management alternatives in terms of their effectiveness, feasibility, cost and schedule to implement for management of lake eutrophication and aquatic vegetation. Ultimately, a whole-lake alum treatment was recommended as the primary lake management alternative to improve water quality. The alum treatment design and total aluminum dose were determined based on sediment phosphorus analysis as well as water column phosphorus concentrations.

o Biological and Habitat Sampling

i. A two-person field team with considerable knowledge and background in biological science and environmental science would follow approved Stream Ecosystem Monitoring (SEM) sampling methods as detailed in ADEQ’s Surface Water Sampling Standard Operating Procedures manual. Field teams would be familiar with the USEPA’s bioassessment methods and indexes of biological integrity, proper functioning condition of riparian areas method, riparian vegetation taxonomic identification, macroinvertebrate taxonomic identification, benthic algae sampling methods, and Rosgen stream type identification and pebble counts.

1. Macroinvertebrate sampling would be conducted to assess the aquatic and wildlife designated use of perennial streams. ADEQ has developed two Indexes of Biological Integrity: Warm water and Cold water. Habitat evaluations would be used to assess channel, riparian and habitat conditions, and potential stressors on macroinvertebrate communities.

Chlorophyll protocols would be those from EPA’s 2013 National River and Stream Assessment methods and periphyton/benthic algae protocols would be based on the EPA’s Multihabitat Sampling Approach from the Rapid Bioassessment Protocols. A site habitat assessment would provide ecological information needed to interpret macroinvertebrate bioassessments and bottom deposits and habitat and chemistry data would provide an ecological context in which to place the macroinvertebrate data.

Causes and sources of aquatic life impairment would be identified using chemical, physical, biological, and land use information produced in a broader habitat assessment, which would consist of the following:

a. Stream reach aesthetics

b. Rosgen stream type identification

c. Reach length and complexity

d. Reach observations

e. Depositional features

f. Pebble counts

g. Riffle geometry

h. Canopy density

i. Riparian species

j. Biological observations throughout reach

k. Regeneration potential of riparian trees

l. Riparian vegetation cover

m. Non-point source observations

n. Pfankuch channel stability evaluation

o. Proper functioning condition assessment

p. Habitat assessment

ii. Tetra Tech performed riparian vegetation taxonomic identification at several riparian sites in a wide range of broader habitats as part of Clean Water Act jurisdictional determination work for permitting of ADEQ mine remediation work in 2020 and 2021.

Sites in the Patagonia Mountains of southeastern Arizona and the Bradshaw Mountains of central Arizona varied in terms of elevation and species present. Tetra Tech biologists routinely conduct biological evaluations and habitat assessments for a variety of projects in Arizona and the Southwest. Senior Environmental Specialist Keith Pohs formerly served as biological science technician and landscape ecologist for the USGS Biological Science Center in Flagstaff and has considerable knowledge of the flora of Arizona.

iii. Tetra Tech also conducted Biological and Habitat Sampling for Boundary Dam FERC Re-Licensing in the Pend Oreille River, WA with Seattle City Light. Tetra Tech assisted Seattle City Light in its FERC hydroelectric relicensing efforts for the Boundary Dam, located near the US-Canadian border on the Pend Oreille River. The goals of this project were to obtain a new FERC license that adequately mitigates environmental and societal impacts while maintaining ratepayer value and operational flexibility. As part of this effort, Tetra Tech conducted numerous technical studies to identify impacts to the environment from hydroelectric operations of Boundary Dam. Along with conducting technical studies, Tetra Tech also worked collaboratively with stakeholders (including Ecology, WDFW, USFW, USFS, USBR, and EPA) and tribal nations (Kalispell and Colville) to develop science-based protection, mitigation, and enhancement measures.

1. Study 1 - Water Quality Constituent and Productivity Monitoring

2. The goal of this water quality and productivity study was to evaluate existing water quality conditions in and immediately downstream of the Boundary Reservoir in support of the application for Section 401 certification and Fish and Aquatics Resource studies. This goal was accomplished by addressing two objectives. The first was to characterize water quality conditions in and immediately downstream of Boundary Reservoir to determine whether the Project meets Ecology’s water quality standards in support of the Section 401 application. The second was to determine water quality, nutrient, primary production, and zooplankton levels in support of the assessment of reservoir productivity being conducted as part of the Fish and Aquatic Resources studies. To meet this second objective, samples were collected seasonally in both the pelagic (mid-river channel) and littoral (shoreline) zones of the reservoir.

3. Study 2 - Relationship of pH and DO to Macrophytes

4. The goals of this study were 1) to assess whether macrophytes are contributing to high pH and low DO readings in Boundary Reservoir, and 2) to investigate potential indirect effects of Project operations on pH and DO via macrophytes. To achieve these goals the magnitude of the impact macrophyte respiration/photosynthesis and senescence have on pH and DO levels was determined. In addition, the effect of Project operations, specifically inundation and frequency of dewatering, on changes in pH and DO in macrophyte beds was also determined.

5. Study 3 - Aquatic Habitat Model

6. The goal of the Mainstem Aquatic Habitat Modeling Study and its component study efforts was to provide quantitative indices of the effects of operations scenarios on aquatic habitats for fish, macrophytes, periphyton, and benthic macroinvertebrates.

7. Study 4 - Sediment Transport and Tributary Delta Habitats

8. The goal of this study was to evaluate the effects of operations scenarios on aquatic habitats in the deltas of major tributary streams within the Boundary Reservoir drawdown zone. The effort also included devolvement of a sediment routing model (HEC-6T) to determine future erosions and deposition for the 50-year term of the new license. The report addressed existing project effects and establishes a baseline condition for the Preliminary License Application (PLP) and License Application (LA). In addition to evaluating the tributary deltas, this study investigated mainstem sediment transport with the goal of evaluating effects of Project operations on channel morphology.

9. Study 5 - Productivity Assessment

10. The goal of the Productivity Assessment study was to determine the effects of current Project operations (e.g., wet, dry, and average hydraulic conditions) and operations scenarios on primary and secondary production in Boundary Reservoir. The objective of this study was to quantify indices of primary and secondary production in reaches of the Pend Oreille River within the Boundary Project area under current (wet, dry, and average hydraulic conditions) and operations scenarios. The Productivity Assessment consisted of evaluating nutrients, phytoplankton, periphyton, and macrophytes as indices of primary production and zooplankton and BMI as indices of secondary production.

o Streamflow Duration Assessment Method (SDAM)

i. A two-person field team with considerable knowledge and background in biological science and environmental science would follow the methods presented in the User Manual for a Beta Streamflow Duration Assessment Method for the Arid West of the U.S. and use the Beta Arid West Field Form. Field teams would be familiar with the EPA’s streamflow duration assessment method (SDAM) survey methods, proper functioning condition of riparian areas method, riparian vegetation taxonomic identification, macroinvertebrate taxonomic identification, benthic algae sampling methods, and Rosgen stream type identification and pebble counts. Field teams would record the following at the requested sites:

ii. Tetra Tech conducted streamflow duration assessments at several sites in a wide range of broader habitats as part of Clean Water Act jurisdictional determination work for permitting of ADEQ mine remediation work in 2020 and 2021. Sites in the Patagonia Mountains of southeastern Arizona and the Bradshaw Mountains of central Arizona varied in terms of elevation and flow. Eleven Level 1 indicators of the Hydrology Protocol for the Determination of Uses Supported by Ephemeral, Intermittent, and Perennial Waters, published by the Surface Water Quality Bureau of the New Mexico Environment Department (NMED 2011), were used to determine flow regime as follows: 1) Water in the Channel, 2) Filamentous Algae and Periphyton

3) Differences in Vegetation, 4) Riffle-Pool Sequences and 5) Absence of Rooted Upland Plants in Streambed, 6) Fish, 7) Benthic Macroinvertebrates, 8) Hydric Soils, 9) Sinuosity, 10) Sediment on Plants or Debris, and 11) Particle Size or Stream Substrate Sorting. Tetra Tech is familiar with the EPA’s Stream Duration Assessment Method (SDAM) including the method’s basis and decision process and its five primary indicators: hydrophytic plant species, aquatic invertebrates, EPT taxa, algae, and fish.

iii. Poland Walker Tunnel (ADEQ)

1. Tetra Tech conducted Stream Gauging using a Marsh McBirney meter at various locations along Big Bug Creek in addition to ongoing pressure transducer data collection at the Poland Walker Tunnel outflow point. The variances in flow throughout the year were compared to the changes in water chemistry. The data were analyzed and used to determine remediation methods and to locate contamination sources as they entered Big Bug Creek.

o Groundwater Sampling

i. A one-two person field team with considerable knowledge and background in groundwater science and hydrogeology would follow the proper well purging techniques for the given sampling site and well. Well purging techniques include:

Low-Flow purging, the Well-volume approach, and Low permeability formation procedures. Groundwater sample collection methods include: Low-Flow approach, submersible pump sampling, peristaltic pump sampling, bailer sampling, and passive diffusion bags.

ii. ADEQ Tanks (Tucson Mountain Motors, Diamond Car Care, Fuentes Auto)

1. Low-Flow Sampling conducted at various ADEQ Tanks sites

2. Groundwater sample results were plotted and used for plume delineation mapping and to determine the remediation plan

3. Soil Vapor Extraction (SVE) and Air Sparge remediation methods were used

iii. City of Flagstaff Rio De Flag

1. Low-Flow Sampling conducted at various monitor wells to analyze for VOCs

iv. Luke Air Force Base Test Borehole 20

Composite sample collection during variable rate testing and constant rate testing; both the depth-specific and composite samples were analyzed for pH, TDS, arsenic, nitrate, phosphate, calcium, magnesium, sodium, potassium, alkalinity, chloride, iron, silica, manganese, vanadium, zinc, fluorides, sulfates, temperature, perchlorate, hexavalent chromium, trivalent chromium, vanadium, strontium,

3. New Source Approval sample collected during the constant rate testing o Fish Tissue Sampling

i. Fish tissue samples would be collected to determine risks to human health from pollutants. Contamination of aquatic resources has been documented for heavy metals, pesticides, and other complex organic compounds in Arizona water bodies.

Once contaminants reach surface waters, they may be available for bioaccumulation, either directly or through aquatic food webs. Results from fish tissue monitoring can serve as an important indicator of further contamination of sediments and surface water.

ii. A two-person field team with considerable knowledge and background in the biological sciences and fisheries would follow the methods presented in the Standard Operating Procedures for Surface Water Quality Sampling prepared by the Surface Water Section of ADEQ in March 2018. These procedures are used by the ADEQ’s fish consumption advisory program to collect and process fish tissue samples to be analyzed for chemical contaminants and are based on established guidelines described in EPA’s 2000 guidance for assessing chemical contaminant data for use in fish advisories. For collections on lakes and non-wadeable streams, a boat-mounted electrofisher, gill nets, or cast nets would be used to collect samples. Collections on wadeable streams would be accomplished using backpack electrofishing techniques, cast nets, or gill net “traps.”

iii. Species information, weight and length measurements, and visible signs of disease such as lesions or sores would be collected in the field. Tissues would later be analyzed for metals and organics. Individual fish species would be identified under the supervision of an experienced biologist familiar with Arizona fish fauna.

iv. Tetra Tech conducted Fish Tissue Sampling as part of the San Juan River Fish Tissue Contaminant Study for the Navajo Nation EPA. In 2015, the plume from the Gold King Mine (GKM) wastewater release flowed through tribal lands, subjecting downstream waters to high metal concentrations. Concerns remained regarding possible resuspension and remobilization of metals in sediments, and latent exposures to aquatic life or humans. The Navajo Nation Environmental Protection Agency (NNEPA) recognizes the importance of recreation in the San Juan River basin, including fishing, and the potential exposure of humans to contaminants through fish consumption. It is because of that recreational importance and the possibility of latent human exposure to metal contamination that NNEPA contracted Tetra Tech to design and conduct the 2017 San Juan River Fish Tissue Contaminant Study. The goal of the study was to provide a screening level assessment of metals in fish fillet tissue to help identify the prevailing human health risk associated with fish consumption subsequent to the GKM toxic release. Tetra Tech prepared a Quality Assurance Project Plan and a sampling Plan for the study, and both were reviewed and approved by NNEPA and USEPA. Channel Catfish (Ictalurus punctatus) were selected as an indicator species based on their ecology, their sportfish status, and human consumption potential; and their relative abundance in the river. Tetra Tech and Navajo Nation Department of Fish and Wildlife collected catfish from two designated river reaches, one from Fruitland to Shiprock, NM and one from Aneth to Montezuma Creek, UT. A total of 10 composite fish samples (50 fish) were collected in April 2017.

Tetra Tech’s Biological Research Facility prepared fillet homogenates for each of the samples and submitted them for analysis of a suite of 25 metals. Analytical results were compared to USEPA risk-based fish consumption limits to characterize relative human health risk and were detailed in Tetra Tech’s technical report submittal to NNEPA. The final report provided current information on metals in San Juan River fish fillet tissue as well as baseline data for any future studies of temporal trends.

v. Tetra Tech also conducted Fish Tissue Sampling as part of the National Study of Contaminants of Emerging Concern and Legacy Contaminants in Fish from U.S. Rivers for the USEPA Office of Water, Office of Science and Technology, and Standards and Health Protection Division. U.S. EPA is conducting a special study under The Office of Water’s National Rivers and Streams Assessment (NRSA) to investigate the occurrence and extent of contaminants of emerging concern (CECs) and legacy contaminants in fish from U.S. rivers. Beginning with the 2008-09 survey, Tetra Tech provided support for the design of this screening study of water and fish tissue samples collected from 150 statistically representative urban river sites throughout the country, and for the preparation of associated quality assurance and sampling plans. This represented EPA’s first broad assessment of CECs (i.e., 30 pharmaceutical compounds, 13 perfluorinated compounds including PFOA and PFOS, and musks) on a national scale using a statistically-based sampling design. Tetra Tech facilitated training throughout the country for study participants, led preparation of the quality assurance project plan for sample collection activities, and coordinated water and fish sampling activities in 48 states. Tetra Tech continues to provide assistance with the sample collection, sample analysis, data analysis, and data review phases for the 2013-14 and 2018-19 survey cycles. Water samples and fish fillets are being analyzed for mercury, PCBs, and CECs, with a focus on potential human health risks. Tetra Tech is currently providing support to EPA for data analysis, public outreach material preparation, and reporting tasks including preparation of peer reviewed journal articles.

Event Scope and deliverables, include number of resources engaged in project, timeline of project (major milestones)

The subject project involved conducting an assessment of the former Salero Mine site, completing additional site investigations to supplement previously completed efforts and develop an approach to remediate or mitigate exposed on-site source areas including waste rock, tailings, discharge from two of the adits on-site, and hazardous mine openings throughout the site. The majority of this work has been performed by Tetra Tech for the ASARCO Multi-State Environmental Custodial Trust, under guidance and oversight by the ADEQ, however, recent activities have been performed directly for the ADEQ. Tetra Tech completed the material sampling and characterization of source areas to develop a closure plan to remediate waste rock areas, close the adits leaking acid rock drainage, and close the evaporation ponds. This plan was approved by ADEQ, and remediation activities were initiated in June 2014. Work that was completed in June and July 2014 included reclamation of four waste rock areas utilizing suitable cover material sourced in the area as confirmed by sampling. Areas were then re-seeded and erosion control measures placed. From October 2016 to February 2017 the plugging and reclamation of the two Adits was completed. An addendum to the original work plan to close the evaporation ponds was submitted and approved on June 13, 2017. Closure of the ponds was completed in October of 2017. Additional funding was provided by ADEQ in 2018 to complete remaining closure activities at the Salero site. A second addendum was submitted to the ADEQ and approved on April 26, 2018 for closure of Upper Royal Blue, Upper Bland, the Waste Rock 5 adit, the roadside tailings pile, and closure of identified unsafe open adits or shafts on-site. This work was completed in June 2018.

Approximately 15 technical staff were utilized on the project. The approximate cost of the completed project was $1.6 Million.
