Appendix A Grant for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 1 Appendix A Project Description This project will continue the work to investigate per- and polyfluoroalkyl substances (PFAS) at Oakland County International Airport (PTK or Airport, Facility ID No. 63005342) that has been ongoing since 2019 and will further determine the nature and extent of PFAS impacts in groundwater on and off Airport property. This project will fulfill the following objectives: • Testing and Monitoring: o Identify the presence or absence of PFAS in groundwater on Airport property. In particular, in the vicinity of the northwestern (i.e., the area located north of Taxiway D and west of Taxiway M) and northern (i.e., area located north of Taxiway D and northwest of the Aircraft Rescue Fire Fighting [ARFF]/Maintenance building) portions of the airfield. Additionally, in the eastern portion of the property (i.e., grassy area located east of Airport Road and south of Tubbs Road). o Identify the presence or absence of PFAS in groundwater off Airport property at 7580 Highland Road, which is in the vicinity of the southwestern corner of PTK property (i.e., north of Highland Road and east of Sherwin Court). o Further determine the nature and extent of PFAS impacts in groundwater off Airport property in the vicinity of the southeastern corner of PTK property (i.e., the area located east of Airport Road and north of Northridge Circle). o Continued monitoring of PFAS impacts in groundwater near the nine (9) known releases of aqueous film-forming foam (AFFF) on Airport property and existing off-site monitoring wells (i.e., MW26-17 and MW26-18) located at 5983 and 6743 Highland Road. o Delineate soil impacts at past known AFFF release areas (i.e., suspected source areas); in particular, grassy areas near MW-5 and MW-8/MW-9. Appendix A Grant for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 2 • Equipment Cleanout: o Transition one (1) aircraft rescue and firefighting (ARFF) vehicle equipped with AFFF for the use of fluorine-free foam (F3) (“equipment cleanout and replacement” funding category). It is expected that the proposed work will be completed by the end of December 2027, assuming grant award and executed grant agreement by September 15, 2026. Contents This grant application is organized as follows: • Conceptual site model and background: Pages 3-9 • Work Plan: Pages 10-16 • Schedule: Page 17 • Budget: Page 18 • References: Page 19 Appendix A Grant for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 3 Conceptual Site Model The Airport is a general aviation and commercial service airport located approximately one (1) mile from the center of Waterford Township in Oakland County, Michigan. A general layout of the Airport, which covers approximately 750 acres, is shown in Figure 1, along with the nine (9) known locations where AFFF was released in the past (1996 to present). The Airport is bounded on the south by State Highway M-59 (Highland Road), on the west by Williams Lake Road, on the east by Airport Road, and on the north by Hatchery Road and North Service Drive. Topography Topography at the Airport is nearly level and ranges from approximately 960 feet North American Vertical Datum of 1988 (NAVD 88) to 996 feet NAVD 88; slightly higher elevations are located in the south-central portion of Airport property. There is also a topographical gradient to the southeast towards Clinton River. Hydrology The Airport straddles the Pontiac Lake-Huron River, Loon Lake-Clinton River, and Pontiac Creek-Clinton River watersheds. The western portion of the airfield is located within the Pontiac Lake-Huron River watershed, a 21 square mile subwatershed of the Woodruff Creek-Huron River watershed, which drains into Lake Erie (via the Huron River). The northern portion of the airfield is located in the Loon Lake- Clinton River watershed, a 26 square mile subwatershed of the Stony Creek-Clinton River watershed, which drains into Lake St. Clair (via the Clinton River). Lastly, the southern portion of the airfield is in the Pontiac Creek-Clinton River watershed, a 48 square mile subwatershed of the Stony Creek-Clinton River watershed, which again drains into Lake St. Clair (via the Clinton River). Surface water bodies in close proximity (i.e., within a 1-mile radius) to the Airport include Clinton River to the southeast, Clam Lake (northeast), Huntoon Lake (northeast), Lake Goodrich (south), Lotus Lake (north), Pontiac Lake (west), Watkins Lake (southeast), White Horse Lake (south), and Williams Lake (north). According to National Oceanic and Atmospheric Administration (NOAA) records, average annual precipitation at the Airport is about 30 inches. All stormwater runoff from PTK’s property is conveyed by catch basins and storm sewer drains to the Airport’s oil/water separator (located near the southern Appendix A Grant for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 4 property boundary along Highland Road) and storm effluent is subsequently discharged into the Wilmont Relief Drain at Outfall 001 (see black triangle on Figure 1). Geology According to the Farrand and Bell (1982) and Leverett and Taylor (1951), Quaternary geology (or surficial geology) in the vicinity of the Airport consists of the glacial deposits comprised of glacial outwash sand and gravel overlain by postglacial alluvium (Farrand and Bell, 1982 and Leverett and Taylor, 1951). The outwash channel is known as the Drayton Gravel Plain. Bedrock geology underlying the Drayton Gravel Plan is the Coldwater Shale, which is a Mississippian-age geologic formation that is composed predominantly of gray to bluish-gray shale that underlies much of Michigan's Lower Peninsula. The Drayton Gravel Plain, where Oakland County International Airport is located, is a distinct outwash plain bounded and separated from adjacent areas by morainic ridges. It is separated from the Commerce Gravel Plain to the south by a ridge extending northwestward from Orchard Lake to White Lake, and from the Oxford Gravel Plain to the north by another ridge extending eastward from the village of Clarkston. Geologically, the Drayton Gravel Plain was formed primarily by meltwater from the retreating Saginaw ice lobe. This origin is reflected in its present day topography, which slopes southeasterly from the Saginaw lobe's moraine toward the Clinton River. The Clinton River forms the southeastern boundary of the gravel plain and served as the principal drainage pathway for glacial meltwater. According to the United States Department of Agriculture (USDA) Soil Conservation Service (SCS; no known as the Natural Resource Conservation Service [NRCS]), unconsolidated material at the Airport consists of soil associated with the Blount-Oshtemo-Houghton Association, which states the soil in this part of Oakland County are deep, very poorly and well drained loamy and organic soils on depressional to steep topography. They have low to very high available water capacity, and rapid permeability (USDA SCS, 1981). Furthermore, soil borings advanced during recent investigations show that the geology consists of mostly brown or gray fine to coarse grained sand, with some interbedded layers of silty sand, clayey sand, silt, and clay. Bedrock geology was not encountered in any advanced boring. Appendix A Grant for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 5 Hydrogeology Groundwater is relatively shallow, with saturation starting at approximately eight (8) feet below ground surface (bgs). Saturation was observed at a deeper depth in MW-14, with a depth to water measurement of approximately 35.5 feet bgs; however, MW-14 is located within the topographically higher portion of the Airport. Overall, groundwater elevations range from approximately 964.5 to 949.5 feet NAVD 88. Soil borings conducted as part of site investigation activities at PTK have been drilled up to 50 feet bgs, which show the aquifer extends to at least that depth in the vicinity of the Airport. Static water level measurements from monitoring wells at the Airport show groundwater flow is primarily to the south, with a slight southeasterly component as shown on Figure 2. Summary of Groundwater PFAS Impacts The groundwater investigations completed to date were performed both on and off Airport property; particularly, near the known AFFF release areas (i.e., on PTK property) and off PTK property at 5983 Highland Road and 6743 Highland Road. Results from these investigations indicated the presence of PFAS in groundwater in these areas; specifically, PFOA, PFOS, PFHxS, PFBS, PFHxA, and PFNA (see Figure 3). However, the detections of PFHxA were under respective Part 201 drinking water criterion. Previous groundwater investigations also suggest the following observations: • PFHxS is the most commonly detected PFAS in groundwater at PTK. • Analytical results indicate that MW-8 and MW-9, located near the ARFF/Maintenance building, and MW-5, located south of Taxiway D and east of Taxiway H, have the highest concentrations of PFAS. • PFAS impacts have been detected in groundwater monitoring wells installed along the Airport’s southern boundary. Appendix A Grant for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 6 Data Gaps The following data gaps currently exist at PTK: • PFAS impacts in groundwater off Airport property in the vicinity of the southeastern corner of PTK property have not been fully delineated. • Potential PFAS sources upgradient of the Airport have not been fully investigated; especially, along the northern property boundary. These data gaps will be addressed by scope of work detailed in the Phase 2 Subsurface Investigation (Task 2) and Groundwater Monitoring Well Sampling (Task 3) portion of grant funding under this grant request.

Testing Grant Funding Work Plan The purpose of the requested grant funding for sampling is to determine the absence or presence of potential PFAS impacts in groundwater in the northern, northwestern, and eastern portions of the Airport and in the off-site property adjacent to the southwestern portion of Airport property. Additionally, grant funds will be used to further delineate PFAS impacts in groundwater detected in the vicinity of the southeastern corner of PTK property. Grant funding is also requested for the continued monitoring of PFAS impacts in groundwater near the nine (9) known AFFF release areas on Airport property and observed PFAS impacts at off-site monitoring wells located south of Airport property. The scope of work to be completed is summarized below. Task 1. Quality Assurance Project Plan and Sampling Plan (Grant Administration) A quality assurance project plan (QAPP) will be prepared describing the data quality objectives for the sampling effort, as well as the data quality assurance measures to be taken during sampling to ensure that the data are accurate and reliable. A field sampling plan will be prepared describing the sampling work to be performed, reflecting any modifications made to the plan between this application and implementation of the work. Other pre-field work will be completed under this task as well, including coordination of utility clearances, preparation of a health and safety plan, and coordination of field activities with Airport operations. The QAPP will be submitted to EGLE for review and approval prior to the commencement of any monitoring activities under this grant. Task 2. Phase 2 Subsurface Investigation (Investigation and Sampling) This second phase of the investigation will include the advancement of soil borings, installation of new permanent monitoring wells, and groundwater sampling on and off Airport property (Figure 4). The Phase 2 Subsurface Investigation work will consist of the advancement of five (5) soil borings, installation of five (5) new permanent monitoring wells, and the groundwater sampling of the five new monitoring wells as shown on Figure 4 (see wells labelled MW #1 through MW #5). One (1) groundwater sample will be collected from each monitoring well, for a total of five (5) groundwater samples. Appendix A Grant Application for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 11 Figure 4. Proposed and Existing Monitoring Well Sampling Locations at PTK. Appendix A Grant Application for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 12 All sampling performed under this scope of work will be performed in accordance with EGLE PFAS sampling guidance and applicable LimnoTech standard operating procedures. Samples will be submitted for PFAS analysis via United States (U.S.) Environmental Protection Agency (EPA) Method 1633 or EPA Method 8327 to either SGS North America or Eurofins for analysis. The final lab selection will be made based on ability to measure all required analytes, ability to achieve necessary method detection limits, ability to meet required turnaround time, and cost. All results will be submitted to EGLE upon receipt from the lab. If permission (i.e., access) to install the two (2) off-site monitoring wells is denied or is not obtained within an acceptable timeframe, these wells will be relocated and converted to onsite wells (i.e., installed on Airport property likely along the northern property boundary). Task 3. Groundwater Monitoring Well Sampling (Investigation and Sampling) This task will include supplemental groundwater sampling and the collection of static waters levels from monitoring wells that were installed during previous investigations at PTK (Figure 4). Specifically, one (1) full set of groundwater samples will be collected from the twenty-four (24) existing groundwater monitoring wells (i.e., one [1] groundwater sample per well) and one (1) full round of static water levels will be collected. These data are intended to verify groundwater flow direction, assess groundwater impacts, and detect plume movement, if any. Again, all sampling performed under Task 3 will be performed in accordance with EGLE PFAS sampling guidance and applicable LimnoTech standard operating procedures. Samples will be submitted for PFAS analysis using EPA Method 1633 or EPA Method 8327 to the same lab that was selected for Task 2 samples. Appendix A Grant Application for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 13 Task 4. Soil Sampling in AFFF Release Areas (Inspection and Sampling) Under this task, soil borings and discrete soil sampling will be performed in the vicinity of the a few of the known AFFF release areas (Figure 5); specifically, in the grassy area near MW-5 (located south of Taxiway D and east of Taxiway H) and the grassy areas near MW-8 and MW-9 (located in vicinity of the ARFF/Maintenance building). The exact number and location of proposed soil borings will depend on the budget remaining following completion of Task 2 and Task 3. However, it is anticipated that the source area delineation will likely include the following elements: • Advancement of at least twelve (12) soil borings. Again, the exact number and location of these borings, and perhaps additional borings, will depend on budgetary constraints. • Soil borings will be advanced to a depth of approximately twelve (12) feet bgs or until top of saturation is encountered, whichever is shallower. • Soil samples will be collected at the following approximate intervals: o Shallow soil sample – 0’-1’ bgs; o Intermediate soil sample – 5’-6’ bgs; and o Deep soil sample – immediately above the top of saturation (approximately 10’-11’ bgs). Again, all sampling performed under Task 4 will be performed in accordance with EGLE PFAS sampling guidance and applicable LimnoTech standard operating procedures. Samples will be submitted for PFAS analysis using EPA Method 1633 to the same lab that was selected for Task 2 and Task 3 samples. Task 5. Data Review, Mapping, and Reporting (Grant Administration) Under this task, data generated from field sampling activities will be compiled, undergo quality assurance review, and mapped. A final report will be prepared describing all field activities completed under the grant and presenting the data and findings with text, tables, and figures. Thirty (30) days prior to the end date of the grant agreement, a draft final report will be provided to EGLE for review and comment. The final report, incorporating EGLE’s comments (if any), will be submitted to EGLE within thirty (30) days from the end date of the agreement. Task 6. Grant Management, Quarterly Status Reports (Grant Administration) This task includes work necessary to manage the grant, including coordination and communication with EGLE personnel regarding field activities, preparation of quarterly status reports, and meetings with EGLE and other stakeholders (including preparation of presentation materials for those meetings).

Proposed Soil Boring and Soil Sampling Areas at PTK. Appendix A Grant Application for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 15 Equipment Cleanout Grant Funding Work Plan Requested grant funding for equipment cleanout in the transition to F3 use will be used towards removing AFFF from the foam tanks of PTK’s 2019 Oshkosh Striker 4x4 vehicle that has a water tank capacity of 1,500 gallons and a foam tank capacity of 210 gallons. Task 7. ARFF Vehicle Cleanout Implementation PTK plans to use an experienced F3 transition contractor to remove AFFF from the ARFF vehicle that can meet the requirements defined in this work approach. Taplin Group was initially selected to perform the work; however, PTK plans to reach out to other F3 transition contractors and airports that have undertaken F3 transitions before deciding on a contractor to perform the work. Regardless of who is selected, all work will need to be in accordance with the following approach. The transition to F3 will include both the bumper turret and handline hose. A multiple-rinse procedure with post-rinse testing to verify the level of PFAS removed will be requested. Rinsing fluids for the process will be asked to be free from any detectable concentrations of Comprehensive Environmental Response, Compensation, & Liability Act (CERCLA) listed hazardous substances. All rinse water used for this process will need to be collected and treated for the removal of PFAS prior to offsite discharge, with certifiable removal requested prior to an offsite discharge that meets applicable federal, state, and local environmental regulations. Taplin Group proposed use of the PFASigator technology developed by Enspired Solutions using photoactivated reductive defluorination (PRD) to break down PFAS molecules from rinse and other waste generated by the rinsing process. AFFF concentrate removed from the truck was also proposed to be sent for offsite destruction which included documentation verifying the destruction of the concentrate by disposal facility staff. Should a different contractor be selected to perform the work, a similar process will be requested using a destructive technology to breakdown PFAS in rinse and offsite disposal of AFFF removed from the ARFF vehicle. The contractor selected for the work will be responsible for the offsite discharge including the coordination for applicable permitting that may be needed. Contractors will be asked for details about the estimated volume of waste that will be generated requiring off-site disposal. This will include rinse water, rinse water sediments, slurry, filter media, etc. as well as waste streams generated during demobilization/rinsing of the technology equipment. Should replacement of a vehicle component be needed to achieve a mass reduction in detected PFAS Appendix A Grant Application for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 16 compounds, the contractor will be asked to provide a list of anticipated vehicle components for grant reimbursement consideration at the discretion of EGLE. Use of a laboratory certified by the U.S. EPA using Method 1633A in analyzing the removal of PFAS from the waste stream will be requested. For implementation of the work, secondary containment of all equipment containing contaminated media, products, or waste will be required. Any temporary storage of contaminated materials during the rinsing process will be required to be in closable containers. After the process to remove AFFF is complete, testing for the absence of PFAS compounds from the ARFF vehicle will be requested for both the bumper turret and handline hoses. An overview for inclusion in the final report will be requested summarizing the entire effort including details of mobilization, the approach used to remove AFFF, the method to dispose of waste, and the sampling results of rinse material prior to disposal. Documentation of the sampling to determine how much PFAS have been removed from the ARFF vehicle and the process to equip the vehicle with F3 will also be included. Task 6 will also include the completion of the survey provided by EGLE in capturing information such as type of foam used, gallons of foam removed, method of rinsing used, and other similar information. Appendix A Grant Application for Per- and Polyfluoroalkyl Substances (PFAS) Response Activities Oakland County International Airport July 21, 2026 Page | 17 Schedule The anticipated schedule for the completion of Phase 2 Subsurface Investigation (Task 2) and Groundwater Monitoring Well Sampling (Task 3) is presented in the table below, based on the timing of the notice-to-proceed, subcontractor availability, and weather conditions. This proposed schedule allows for the completion of Task 2 work while affording sufficient time to implement the additional sampling event (Task 3).
