RE: Abbreviated Work Plan and Budget for Additional Corrective Action at the Petroleum Release at the Choteau County Maintenance Yard, 26th and Main Street, Fort Benton, Montana; Facility ID 08-05931, Release 3645, Work Plan 34099.

Dear Mr. Riehl:

This work plan presents Water & Environmental Technologies’ (WET) proposed approach and budget for corrective actions at the above-referenced Facility, as required in the Montana Department of Environmental Quality (DEQ) Work Plan Request letter date June 17, 2020.

The objective of this phase of work is to reduce petroleum hydrocarbon concentrations to below Human Health Standards and/or Risk Based Screening Levels (HHS/RBSLs). An earlier version of this workplan, previously submitted on September 29, 2020, included a design for a Ais Sparge and Soil Vapor Extraction (AS/SVE) system and additional monitoring wells. After discussion with DEQ and the Choteau County sanitarian, it was decided that this workplan would be revised to include a more aggressive remediation proposal. The proposed scope of work for this workplan now includes the design of three remediation systems:

System A: Soil Vapor Extraction (SVE). System B: Air Sparge and Soil Vapor Extraction (AS/SVE) system. System C: Air Sparge system.

Given the depth of the contamination and the relatively high hydraulic conductivity of the subsurface, the three systems proposed in this workplan provide an effective path for promoting removal and degradation of smear-zone impacts. WET’s approach to complete the scope of work is detailed below.

Project Management Project management activities will include routine communication with DEQ and Choteau County Commissioners throughout the project, scheduling field activities and staff, project invoicing, and meeting with prospective contractors to discuss the scope of work (pre-bid and pre-construction meetings).

Mobilization WET personnel will mobilize to the Facility approximately 20 times to implement this CAP. The Facility location is provided in Figure 1. WET will utilize personnel from our Great Falls office as often as possible to minimize mobilization costs. When estimating total project costs, WET assumed a 50/50 split between Great Falls and Butte office staff to complete the project. In the instance that Great


Falls staff are unavailable, staff from Butte will complete the work. Invoices will reflect actual project staffing. Health and Safety Plan WET personnel will prepare a health and safety plan addressing specific safety protocol for the work conducted under this work plan. Noise generated by the operating systems is not expected to be excessive, however noise levels will be assessed in the field for each system, and appropriate solutions, such as further insulating the sheds, will be implemented. Utility Locates Prior to installing monitoring or AS/SVE wells, locations will be cleared of utilities through the Montana One Call system and the use of a private utility contractor. GeoSearch Inc. has been selected to conduct the private utility locations. The three additional down gradient wells proposed in this work plan are located on the public right-of-way, however, should locations be contested by local landowners, an alternative location will be discussed with DEQ prior to installation. The existing and proposed wells are shown on Figure 1. Well Installation and Construction The installation of three additional groundwater monitoring wells is proposed to define the downgradient extent of the dissolved phase groundwater plume south and east of the Facility. Two additional 4-inch diameter wells to be used as soil vapor extraction (SVE) wells are also proposed to be installed within the contaminant plume. Finally, four 1-inch diameter wells are proposed to be installed east and west of the contamination center to serves as air sparge (AS) wells. All wells will be approximately 40-feet deep. Proposed locations for the three monitoring wells, two SVE wells and four AS wells are shown on Figure 1. During advancement of all well borings, soils will be continuously screened using a photoionization detector (PID) and will be characterized using the Unified Soil Classification System (USCS). Three bids were solicited for monitoring well and SVE well installation; Boland Construction was the low bidder and will be awarded the work. Enviroprobe will be contracted to install the AS wells. Subcontractor bids are included as Attachment A. Following boring completion, monitoring wells will be constructed with 2-inch, schedule 40 PVC casing and 0.010-inch factory slotted screen installed across the water table, with a total of approximately 10 feet of well screen. Exact screen lengths and intervals will be determined in the field based on observed zones of contamination, lithology, and historical free product and water level data. Monitoring wells will be developed following installation using a surge block, submersible pump, and/or air lift pump. Construction specifications for AS and SVE wells are detailed in the following sections.

Typical SVE System Design SVE Wells will be constructed with 4-inch schedule 40 polyvinyl chloride (PVC) well casing and 0.020-inch factory slotted screen. The annular space will be filled with 10-20 silica sand to approximately one foot above the screened intervals and sealed to approximately three to five feet below the surface with hydrated bentonite chips. The upper three to five feet of annulus will be backfilled with unimpacted drill cuttings or silica sand. Typical SVE wells will be installed to a total depth of 40 feet and screened 15 feet at the bottom, allowing for effective capture of vadose zone vapors. This screen length is expected to allow for capture of vapors 5 feet above the high groundwater table and up to 15-feet above the seasonal low groundwater table.


Each SVE well will be completed with a 4x4x4-inch PVC T fitting, connecting the well casing to the 4-inch lateral piping, which ultimately connects to the blower manifold. The top of the T fitting will house a threaded cap should access to the well be required. The cap will also be fitted with a quick connect fitting for pressure readings. The laterals will be trenched to the blower manifold that will be housed inside of a small shed. Trenching and manifold details for systems A, B, and C are provided in Figures 3, 4 and 5, respectively. Typical SVE well completion details are provided in Figure 6. The well heads will be completed with flush monuments and cemented in place. Three bids were solicited for well installation; Boland Construction was the low bidder and will be awarded the work. Subcontractor bids are included as Attachment A. Piping laterals will be installed in a trench, approximately 3-feet deep and 2-feet wide, which will extend from each wellhead to a remediation shed. Piping will be bedded in appropriate bedding material such as sand, pea gravel, or road mix to at least 6” above the top of the pipe. The remainder of the trench will be backfilled and compacted using the native soils removed during excavation. The laterals will be installed at a gradient of approximately 1%, sloping up from the individual wells to the shed which will limit the amount of water that enters the moisture separator drum and improve the longevity of the system. Under the remediation shed the pipes will be directed at right angles up through a square cut hole in the shed floor. The pipes will be manifolded together in parallel to a central 4-inch, schedule 40 PVC lateral, connected to a moisture separator drum and then the vacuum blower (Attachment B). The blower exhaust will be vented to the atmosphere. A 4-inch PVC ball valve will be installed on each well leg allowing discreet flow adjustments to individual wells. Sample ports and gauges will be installed on each well leg, the main manifold, and the exhaust to allow photoionization detector (PID), vacuum pressure, and flow rate measurements to be collected at several locations. Process and instrumentation diagrams for the AS/SVE systems (A, B, and C) are included in Figures 3, 4 and 5, respectively. The blower can produce 195-cubic feet per minute (cfm) at a vacuum pressure of 60-inches of water (iow) at a frequency of 60 Hz. Three bids were solicited for trenching and system construction. M&D Construction, Inc. was the low bidder and will be awarded the work. Subcontractor bids are included as Attachment A. SVE well construction details are provided in Figure 6.

As part of system installation, a new single-phase electrical service will be installed on-site to provide power to the AS/SVE system sheds. Three bids were solicited for electrical installation and are included as Attachment E. United Electric was the low bidder and will be awarded the work. Typical AS Design

AS Wells will be constructed with 1-inch schedule 40 polyvinyl chloride (PVC) well casing. AS wells will be installed to a depth of approximately 40 feet, or 10 feet below the high-water table. The bottom 2.5-feet of the injection well will be constructed out of 0.020-inch factory slotted screen. This depth will allow for effective year-long sparging of the upper portion of the groundwater table. The annular space will be filled with 10-20 silica sand to approximately one foot above the screened intervals and sealed to approximately three to five feet below the surface with hydrated bentonite chips. The upper three to five feet of annulus will be backfilled with unimpacted drill cuttings or silica sand. AS wellheads will be completed similarly to the SVE wellheads. Each AS well will be completed with a 1x1x1-inch PVC T fitting, attached to the well casing and the 1-inch HDPE lateral connected to the compressor manifold. The top of the T fitting will house a threaded cap should access to the well be required. The cap will also be fitted with a quick connect fitting for pressure readings. The laterals will be trenched to the compressor manifold that will be housed inside of a small shed. Trenching and manifold details are provided in Figures 3, 4 and 5. Typical AS well completion details are provided in


Figure 7. The well heads will be completed with flush monuments and cemented in place. Enviroprobe will be contracted to install the AS wells. Subcontractor bids are included as Attachment A. As shown in Figure 7, the 1-inch PVC of the AS wells will connect to 1-inch high-density polyethylene (HDPE) pipe, which will also be trenched to a hole in the in the utility shed. The HDPE will be barbed and stepped up to 2-inch steel pipe, connected by a manifold to a main air supply line. A heat exchanger will be plumbed between the C-DLR-60 air compressor and the manifold, to maintain low injection temperatures. The C-DLR-60 air compressor (Attachment C) produces an airflow of approximately 40 cubic feet per minute (cfm) at 60 pounds per square inch (psi). Each AS line will receive approximately 10 to 15 cfm. Air sparge wells are assumed to have a zone of influence similar to that of SVE wells (40-feet).

System A Design System A will be comprised of four SVE wells be located across the center to northeast corner of the Facility parcel. Each SVE well of System A is expected to extract approximately 40 cfm of air, at an expected vacuum of 15 to 20 iow. Actual wellhead vacuum and pressure losses from the blower to the wellhead will be assessed in the field. The air flow will be provided by a Gast R5125Q-50 Blower that will be repurposed from pervious remediation work at this Facility. The proposed well locations and their expected zones of influence (ZOI) are displayed on Figures 1, 2, and 3. These locations have been selected to treat the area exhibiting the greatest groundwater impacts, while repurposing RW 3-1 and RW 3-2, which are existing product recovery wells. Existing product recovery wells RW3-1 and RW3-2 will be converted into SVE wells and have total depths of 38-feet and 43-feet, respectively. The bottom ten feet of RW-3-1 and bottom 20-feet of RW-3-2 are screened with 0.020 factory slotted screen. The proposed two new SVE wells will have anticipated total depths of 38-feet and a 10-feet screen interval from 28-feet to 38-feet bgs. This screen interval extends 2-3-feet above the historical high groundwater level (30-feet bgs) and 4 feet below the historical low groundwater level (36-feet bgs). Exact screen lengths and intervals will be determined in the field based on observed zones of contamination, lithology, and historical product and water level data. The primary objective during well construction will be to select screened intervals that will provide adequate air flow in the portion of the vadose zone with hydrocarbon impacts, while minimizing short circuiting in un-impacted, shallower zones, where enhanced air flow would not be beneficial.

System B Design System B will consist of both AS and SVE type remediation wells. This system will be located in the vacant lot to the southeast of System A. This well layout was selected after discussion with DEQ to address the downgradient potion of the 1-2 Dichloroethane contamination plume, as well as elevated benzene and naphthalene concentrations, observed in monitoring well MW-18, shown on Figure 1. System B will also utilize existing infrastructure from previous remediation work. The AS/SVE system will be housed in the existing shed onsite and will repurpose existing RW-4 wells from a previous product recovery system installed by WET in 2009. The SVE component of System B, shown on Figures 1, 2 and 4, will include wells RW-1, RW-2, RW-3, and RW-4. Each of these wells was installed to a depth of 40-feet bgs and are screened from 40-feet to 20-feet bgs. This will result in 10-feet to 15-feet of screen available for soil vapor capture. The vacuum will be provided by a Gast R5125Q-50 Blower (Attachment B) that will be repurposed from previous remediation work at this Facility. The pipes will be manifolded together in parallel to a central 4-inch, schedule 40 PVC main lateral line connected to an air/water separator (KO Drum) and then the vacuum blower. The blower


exhaust will be vented to the atmosphere. A process and instrumentation diagram is included as Figure 4. Each SVE well of System B is expected to receive approximately 40 cfm of flow, at an expected vacuum of 15 to 20 iow. Actual wellhead vacuum and pressure losses from the blower to the wellhead will be assessed in the field. Well details for the SVE wells are provided in Figure 6. The AS component of System B will include three 1-inch AS wells, shown in detail on Figure 4. AS Wells will be constructed with 1-inch schedule 40 polyvinyl chloride (PVC) well casing. AS wells will be installed to a depth of approximately 40 feet, or 10 feet below the high-water table. This depth will allow for effective year-long sparging of the upper portion of the groundwater table. Air Sparge well completion details are provided in Figure 7. The three AS laterals will be trenched to a centrally located utility shed, where the pipes will be directed at right angles up through a square cut hole in the shed floor. The AS laterals will be manifolded together in parallel and connected to a C-DLR-60 Claw Compressor (Attachment C). Each of the three wells will received approximately 20 cfm of air flow.

System C Design

After discussion with DEQ, additional work has been requested to remediate the elevated benzene and naphthalene concentrations observed to the northwest of the county shop building, in monitoring well MW-26 (see Figure 1). System C will consist of a single air sparge well located near MW-26 as shown on Figure 1 and Figure 5. This system is located far enough from structures that vapor accumulation in buildings should not be a concern. Vacuum readings will be taken at nearby wells (RM 2-1 and RW-1) as part of the system startup activities to quantify the extent of the pressure influence and verify that it does not extend into any residences or workplaces. Air samples will also be collected from these wells by evacuating the stagnant air in the well with a vacuum box before filling a tedlar bag, using a hand pump or vacuum box to fill. The bags will then be field screened with a photo ionization detector (PID). A small shed that was used during previous remediation work at the Facility, currently located downhill of the proposed location, will be relocated and used to house System C. As shown in Figure 7, the 1-inch PVC of the AS well will connect to 1-inch high-density polyethylene (HDPE) pipe, which will also be trenched to a hole in the in the utility shed. The HDPE will be barbed and stepped up to 2-inch steel pipe, connected by a manifold to a main air supply line. The C-DLR-60 Claw Compressor (Attachment C) produces an airflow of approximately 60 cfm at 60 psi. The single AS line in this system will receive the majority of this air flow. The system relief value will be utilized to adjust air flows to appropriate pressures. These exact values will be determined in the field based on system performance and professional judgement. Investigation Derived Waste (IDW) Drill cuttings will be continuously screened for evidence of petroleum contamination using a sheen test and a photoionization detector (PID) and the heated headspace method. If cuttings display evidence of petroleum contamination including visible sheen, staining, and/or elevated PID readings (>50 ppm), soils will be containerized in 55-gallon drums and one sample will be collected per drum to characterize soil for disposal. Once soils are characterized, WET will request permission for landfill disposal. Excess excavation spoils will be stockpiled onsite and will undergo field PID screening. If all results of field screening are below 50 parts per million (ppm), the material will be land spread on site. If any results of field screening are above 50 ppm, the material will be placed on plastic sheeting and either bermed so that runoff will not occur or covered with a tarp. One five-point composite sample will be collected for each 400 cubic yards of material. IDW will be analyzed for EPH, VPH, and lead scavengers. Following receipt of laboratory analytical results, the material will be land spread if all concentrations are below appropriate RBSLs or characterized and scheduled for disposal at an appropriate facility. Purge water generated from well development and groundwater monitoring will be


disposed of in accordance with the DEQ purge water disposal guidance. The site is located on pervious loose gravel and wells containing free product will not be sampled; therefore, purge water will be discharged to the ground. Should conditions exist that preclude purge water disposal (i.e. impervious ground), purge water will be containerized and properly disposed of. Well Survey Newly installed AS/SVE and monitoring wells will be surveyed for location and top-of-casing elevations by a licensed surveyor. The location coordinates will be presented in the 1983 North American Datum (NAD83), Montana State Plane with units of international feet. Elevations will be expressed in units of feet above sea level (AMSL) relative to the 1988 North American Vertical Datum (NAVD88).

AS/SVE Startup and Optimization, System Checks, Operation and Maintenance WET will conduct monitoring of the remediation system during startup, including both pre-startup baseline monitoring and subsequent quarterly routine system monitoring. Monitoring activities will include a combination of field and laboratory measurements to establish a baseline to evaluate system performance and future monitoring needs. AS/SVE system monitoring will take place on the following schedule:

Baseline laboratory air sampling conducted immediately after system optimization, along with PID, vacuum, and flow rate measurements.

Quarterly checks thereafter, with laboratory air sampling completed each quarter. Flow and velocity at all sample locations will be measured using a handheld air velocity meter. Concentrations of volatile organic compounds (VOCs) in the vapor stream will be collected using a Mini Rae 3000 Photoionization Detector (PID) at all locations during regular O&M events. Vacuum, pressure, and temperature readings will be measured using inline factory gauges. In addition to laboratory air sample collection and routine PID, vacuum, and flow measurements, one respirometry testing event is proposed following approximately one year of continuous system operation. Respirometry measurements will be collected using the procedures outlined in the bioventing pilot test work plan, which was submitted to DEQ on February 7, 2019. Data acquired from respirometry measurements will be used to assess the performance of the AS/SVE system and may aid in estimating the time to release closure and/or determining other future remedial actions at the site. Operation and maintenance costs are estimated for one year following the initial year of operation as the system will continue to run and be maintained during the reporting period and for the duration of any subsequent workplan request, submittal, approval, and fund obligation. AS/SVE System Air Monitoring An air sample will be collected from the SVE vapor stream on Systems A and B immediately after startup and quarterly thereafter for one year from the combined influent line, likely between the vacuum blower and the discharge stack. The samples will be collected in a certified clean Summa canister and submitted to Pace Laboratory in Minneapolis, MN for analysis of the following methods: 3C-Fixed Gas %, TO-3, TO-3M (Methane), TO-13 (PAH), TO-14, TO-15 (Full VOCs), and TO-15 Short List. These analyses will provide results for a wide range of volatile organic compounds, including major BTEX constituents and lead scavengers. Groundwater Monitoring and Water Level Measurements Following installation and development of wells, WET personnel will conduct a baseline groundwater monitoring event of existing facility wells MW-7, MW-8, MW-11, MW-13, MW-14, MW-16, MW-17,


MW-18, MW-21, MW-25R, MW-26, MW-30 along with the three proposed monitoring wells (MW-32, 33, and 34). Monitoring will include measuring depth-to-water and depth-to-product (if present) of all facility wells and collecting groundwater samples from the monitoring wells specified above. If product is detected in a well, that well will not be sampled. Samples will be collected using a portable bladder pump and disposable polyethylene tubing. Monitoring wells will be purged prior to sampling. Purging will be conducted until field parameters stabilize within a 10% difference over a five minute collection interval. If stabilization does not occur after 30 minutes, then the final parameters will be recorded, and the sample will be collected. Groundwater field parameters including temperature, dissolved oxygen, pH, specific conductivity, oxidation reduction potential, and turbidity will be measured during purging, and once parameters stabilize, a groundwater sample will be collected in laboratory-supplied bottles and analyzed for volatile petroleum hydrocarbons (VPH), extractable petroleum hydrocarbons (EPH) and the lead scavengers ethylene dibromide and 1,2-dichloroethane. Samples will be submitted to Energy Laboratories in Helena, Montana. A duplicate and field blank will be collected during each groundwater monitoring event. The duplicate and field blank will be labeled DUP-YYYY-MM-DD and FB-YYYY-MM-DD, respectively. Location collections will be recorded on the field sheet.

WET personnel will conduct a total of three groundwater monitoring events: one prior to AS/SVE system startup (baseline), and two semiannual groundwater monitoring events following AS/SVE system startup. The first semi-annual monitoring event will be conducted approximately 6 months after the AS/SVE system startup, and the second event will be conducted approximately 12 months after the AS/SVE system startup.

Project Reporting Within 90 days of receipt of the last laboratory analytical results, WET will submit a Standardized Generic Applications Report (Report AR-07) that summarizes the field activities discussed in this work plan. The report will contain:

a discussion of project goals and how the system is achieving those goals; discussion for system installation and how the system could be improved or optimized; tabulated PID and soil sampling results; tabulated AS/SVE effluent air sample results; tabulated new and historical groundwater sampling results; a discussion of follow-up reports that will be necessary to report on the remediation system’s

effectiveness; and a discussion of a path to closure for the release.

Schedule WET will begin implementing this work plan upon DEQ approval and funds obligation by the Petroleum Tank Release Compensation Board and will notify DEQ prior to conducting the first field activities. Budget The costs to implement this work plan are estimated to be $218,742.04. A detailed cost estimate is included as Attachment D.
