As you know, periodic groundwater monitoring is required by the MA Department of Environmental Protection (MassDEP) and Brewster Water Quality Review Committee (BWQRC) under the outstanding Administrative Consent Order, through the start of construction, as part of the permitting process for Landfill Closure and Post -Closure Reuse of the former stump dump. Laboratory analyses included standard water quality parameters, total metals, volatile organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs), consistent with the parameters outlined in Appendix A of the Woodwaste Guidance Document (BWP-98-006), and with previous testing. Groundwater samples were collected by BEA personnel on December 12, 2023, from monitoring wells MW -1A, MW -2, MW -3, and MW -4. A Monitoring Well Sampling Log is attached for reference. Prior to sampling, depth -to -groundwater measurements were taken at each monitoring well location. The wells were then purged in accordance with MassDEP standard practices and BEA Quality Assurance & Quality Control (QA/QC) methods. Field parameters measured during sampling activities included temperature, pH, conductivity, dissolved oxygen (DO) and oxidation-reduction potential (ORP). The samples were collected using a variable -speed 2" submersible pump, using low -flow sampling methodology. Sample containers were prepared by Alpha Analytical and kept in a cooler or refrigerator pending pick up by a lab courier and transported following chain of custody procedures. Well gauging data from the date of sampling reports depth to groundwater ranging from 47.62 to 82.72 feet below grade, with groundwater elevations ranging from 25.08 to 23.04 feet (NAD83), as measured from the top of the well casings. The December 2023 gauging event shows groundwater flows southeasterly towards Pleasant Bay, consistent with data from previous monitoring events. Depth -to -groundwater measurements and corresponding elevations are EMERGENCY SPILL RESPONSE 6 WASTE SITE CLEANUP t SITE ASSESSMENT 6 PERMITTING 6 SEPTIC DESIGN & INSPECTION DESIGN BUILD 6 OPERATION & MAINTENANCE 6 WATER SUPPLY DEVELOPMENT 6 WASTEWATER TREATMENT 6 FIELD SERVICES 1 JANUARY 11, 2024 NEXTGRID/K11273 PAGE 2 OF 2 0 MID CAPE HIGHWAY-BREWSTER presented on the enclosed Monitoring Well Sampling Log. Groundwater contours are represented on the enclosed Site Plan. Laboratory results were received on December 28, 2023. The results were compared to the Massachusetts Drinking Water Standards (MDWS), published by MassDEP. These standards include Massachusetts Maximum Contaminant Levels (MMCLs), Secondary Maximum Contaminant Levels (SMCLs) and Office of Research and Standards Guideline (ORSG) concentrations. In addition, the results were compared to the MCP Reportable Concentrations for the RCGW-1 groundwater categories. A tabulation of the laboratory data for the December 2023 sampling event, along with a comparison to the above standards, is presented in Table 1. A comparison with historical data is presented in Table 2. The results reported elevated concentrations of manganese, sodium, and iron in both upgradient and downgradient wells, above the SMCLs, consistent with previous testing. SMCLs are not health -based standards but were established to preserve the aesthetic qualities of drinking water. Manganese was also reported above the ORSG values in MW -4. The ORSG for Manganese considers lifetime exposure (0.3 mg/L) and acute exposure (1.0 mg/L) for the general population, as well as a precautionary standard for acute exposure for children <1 year old (0.3 mg/L). Trace concentrations of Naphthalene were reported in MW -4, and trace concentrations of Chloroform were reported in MW -1A and MW -3, the concentrations reported were all below the corresponding MMCL and RCGW-1 Standards. Otherwise, no significant groundwater impairment was reported with all parameters below the respective MMCLs, or RCGW-1 concentrations. At the time of this reporting, woodwaste recovery operations at the property are complete and BEA is preparing the SW -43 Landfill Closure permit application package for MassDEP review.

Serial_No:12282318:01 Page 3 of 81 NEXTGRID-CULIG K11273 Project Name: Project Number: Lab Number: Report Date: L2373630 12/28/23 Case Narrative The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report. Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter (i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target Compound List, even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE", respectively. When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications. Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located at the back of the report. HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air canisters will be disposed after 3 business days from the date the project is completed. Please contact Project Management at 800-624-9220 with any questions.

SEMI-ANNUAL GROUNDWATER MONITORING REPORT November 2023 Cape Sand & Recycling, LLC Wood Waste Reclamation Facility Brewster, Massachusetts K10740A JANUARY 22, 2024 1 CAPE SAND & RECYCLING, LLC WOOD WASTE RECLAMATION FACILITY (WWRF) SEMI-ANNUAL GROUNDWATER MONITORING REPORT NOVEMBER 2023 SAMPLING EVENT 1.0 INTRODUCTION This Groundwater Monitoring Report has been prepared to provide the Massachusetts Department of Environmental Protection (MassDEP) and the Town of Brewster Water Quality Review Committee (WQRC) with results of the most recent groundwater sampling event, associated with the Wood Waste Reclamation Facility (WWRF) located at 1515 Freemans Way in Brewster, Massachusetts, and currently operated by Cape Sand & Recycling, LLC (CS&R). Groundwater sampling was performed by Bennett Environmental Associates, LLC (BEA) on November 14, 2023. The laboratory analyses were performed by Alpha Analytical, as a laboratory certified to perform the requisite analyses. This report is being filed with the Mass DEP and the BWQRC as part of the conditional approvals for the small WWRF. 2.0 GROUNDWATER MONITORING PROGRAM 2.1 Background On December 29, 2009, the MassDEP issued a Provisional Approval – Authorization to Operate (ATO) a Small Handling Facility/Wood Waste Reclamation to CS&R. The ATO approval included requirements to continue the groundwater monitoring program previously developed to comply with the MassDEP “Wood Waste Reclamation Facilities Siting and Permitting Requirements” Guidance Document - #BWP-98-006 (the WWRF Guidance Document). The ATO approval also declared the Site “Adequately Regulated”, pursuant to the provisions of 310 CMR 40.0110 of the Massachusetts Contingency Plan (MCP). This determination was related to concentrations of arsenic and Bis(2ethylhexyl) phthalate reported in groundwater at the site in November 2007. The concentrations reported exceeded the applicable RCGW-1 Reportable Concentrations, triggering a 120- day release notification requirement resulting in release tracking number (RTN) 4- 21361. The ATO document stated that the Adequately Regulated determination is valid provided that the required monitoring continues and that all previously buried materials be excavated, and any unacceptable materials be removed. On October 19, 2010, MassDEP issued a Provisional Approval – Modification of a Small Handling Facility/Wood Waste Reclamation Facility. The Modification Approval 2 authorized reducing the number of groundwater sampling locations from six (6) monitoring wells to four (4), including MW-1 (later replaced by MW-1R), MW-3A, MW- 4A and MW-5. Based on information submitted by the consultant at the time (Prime Engineering), MassDEP found that the reduction in the number of wells would not compromise the sufficiency of the network to monitor groundwater and would remain consistent with the standard Mass DEP requirements for WWRFs. The Modification Approval document also reaffirmed that the Site had been declared “Adequately Regulated” pursuant to the provisions of both the MCP and the Solid Waste Regulations (310 CMR 19.00). As such, monitoring wells MW-1R, MW-3A, MW-4A and MW-5 are sampled on a semi- annual basis for the parameters included in the Groundwater Monitoring Appendix of the WWRF Guidance Document. Total Phosphorus was added as a parameter in November 2015 at the request of the BWQRC. In addition, the WQRC has requested sampling two (2) additional downgradient monitoring wells (MW-3B and MW-5B), to evaluate groundwater conditions up-gradient of the Timberlane Drive neighborhood, where private potable wells are currently in-use. These monitoring wells are typically sampled for Total Manganese to evaluate concentrations in these downgradient wells. Monitoring wells MW-3B and MW-5B are also sampled for nitrogen-related parameters when concentrations of Nitrate or Nitrate/Nitrite are reported above the MMCL of 10 mg/L, in any of the MW-3A, MW-4A or MW-5 monitoring wells. During the November 2023 sampling event, MW-3B and MW-5B were also sampled for Total Arsenic, and Total Dissolved Solids due to intermittent spikes in concentrations of these analytes reported in MW-3A in May 2020 and May 2022. Monitoring well locations are shown on the enclosed Site Plan. 2.2 Groundwater Sample Collection Groundwater samples were collected by BEA personnel on November 14, 2023, from monitoring wells MW-1R, MW-3A, MW-3B, MW-4A, MW-5, and MW-5B. A Monitoring Well Sampling Log is attached for reference. Prior to sampling, depth-to-groundwater measurements were taken at each monitoring well location. The wells were then purged in accordance with MassDEP standard practices and BEA Quality Assurance & Quality Control (QA/QC) methods. Field parameters measured during sampling activities included temperature, pH, conductivity, dissolved oxygen (DO) and oxidation-reduction potential (ORP). The samples were collected using a variable-speed 2” submersible pump, using low-flow sampling methodology. Sample containers were prepared by Alpha Analytical and kept in a cooler or refrigerator pending pick up by lab courier and transported following chain of custody procedures. 3 2.3 Groundwater Gauging Data Well gauging data from the date of sampling reports groundwater elevations ranging from 20.77 to 22.12 feet above mean sea level, as measured from the top of the well casings. The November 2023 gauging event shows groundwater flows easterly towards Pleasant Bay, consistent with data from previous monitoring events. Depth-to- groundwater measurements and corresponding elevations are presented on the enclosed Monitoring Well Sampling Log. Groundwater contours are represented on the enclosed Site Plan dated 12/5/23. 3.0 LABORATORY ANAYLTICAL RESULTS Laboratory results for the November 2023 sampling event were received on November 27, 2023. The results were compared to the Massachusetts Drinking Water Standards (MDWS), published by MassDEP. These standards include Massachusetts Maximum Contaminant Levels (MMCLs), Secondary Maximum Contaminant Levels (SMCLs) and Office of Research and Standards Guideline (ORSG) concentrations. In addition, the results were compared to the MCP Method 1 Risk Characterization Standards for the GW-1 (ingestion) and GW-3 (discharge to surface water) groundwater categories. A tabulation of the laboratory data for the November 2023 sampling event, along with a comparison to the above standards, is presented in Table 1: November 2023 Groundwater Analysis Summary. The results of semi-annual groundwater data over the past three (3) years are presented in Table 2: Temporal Groundwater Analysis Summary – November 2020 through November 2023. 3.1 Total Metals Groundwater samples collected from MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for Total Arsenic, Barium, Cadmium, Chromium, Copper, Iron, Lead, Manganese, Mercury, Selenium, Silver, and Zinc. Monitoring wells MW-3B and MW-5B were sampled for Total Manganese and Total Arsenic only. Arsenic was reported above the Massachusetts Drinking Water Standard (0.01 mg/L) and the Method 1 GW-1 Risk Characterization Standard in monitoring well MW-1R (0.0578 mg/L) and in monitoring well MW-3A (0.0595 mg/L). All other monitoring wells sampled reported Arsenic as Non-Detect. As previously mentioned, Release Notification was made to the DEP for the presence of similar concentrations of Arsenic in groundwater in 2007 (RTN 4-21361). In 2009, the 4 Site was listed as Adequately Regulated by the DEP and therefore Release Notification is not required. Similar concentrations of Arsenic have been reported in monitoring wells MW-1 (May 2014) and MW-3A (Nov. 2007 and May/Nov. 2012). Arsenic has consistently been reported above the MA Drinking Water Standard and Method 1 GW-1 Standard in monitoring well MW-1R since the well was installed in 2016, with concentrations ranging from 0.0175 mg/L to 0.058 mg/L. The elevated concentrations of total metals reported at MW-1R are attributed to naturally occurring metals leaching from native soils in a reducing environment, as a result of decaying organic matter associated with previously buried wood waste in contact with groundwater in the area where the well is installed. The elevated concentrations of total metals reported at MW-3A may be related to dissolved organic materials leaching to groundwater during the increased rainfall events in the autumn months, wherein higher concentrations are reported during November and the concentrations decrease in May. The effect appears to be limited to a small area, with concentrations of arsenic reported as non-detect in well MW-3B located further downgradient. Total Iron was reported at concentrations exceeding Secondary Drinking Water Standards (SMCLs) in groundwater samples collected from MW-1R, MW-3A, and MW-5. The highest concentration of Total Iron was reported at MW-1R (63.5 mg/L). SMCLs are not health-based standards but were established to preserve the aesthetic qualities of drinking water. In October 2013, MassDEP adopted an Office of Research and Standards Guideline (ORSG) for Manganese, based on a modified version of the US EPA Health Advisory for this element. The ORSG considers lifetime exposure (0.3 mg/L) and acute exposure (1.0 mg/L) for the general population, as well as a precautionary standard for acute exposure for children <1 year old (0.3 mg/L). Total Manganese was reported at concentrations exceeding the SMCL (0.05 mg/L) and OSRG values for chronic and acute exposures in MW-1R, MW-3A, MW-4A, and MW-5. Monitoring well MW-3B exceeded the SMCL and the ORSG value for chronic/infant exposures. Monitoring well MW-5B only exceeded the SMCL. Iron and Manganese dissolve more readily in low oxygen environments and where the groundwater is slightly acidic, which is consistent with conditions at the site. The tracking charts below show concentrations of Total Arsenic, Iron, and Manganese reported during the semi-annual monitoring events since May 2019. 5 0102030405060708090 mg / L Sampling Date Total Iron Concentrations in Selected Wells - May 2019 through November 2023 MW-1R MW-4A MW-3A MW-5 6 3.2 Volatile Organic Compounds (VOCs) Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for VOCs via EPA Method 8260B. No VOCs were reported in any of the wells above the laboratory detection limits. Various compounds that were reported as Non-Detect had reporting limits that exceeded different standards. Though, with the lack of any similar compounds reported no VOCs are presumed present. 3.3 Poly-nuclear Aromatic Hydrocarbons (PAHs) Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for PAHs. No PAHs were reported above the laboratory detection limits in any of the monitoring wells sampled. Future sampling events will continue to monitor PAH concentrations at these wells. 3.4 Aggregate Organic Constituents Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for Tannin & Lignin, Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC). Tannin & Lignin and COD were detected in monitoring wells MW- 1R, MW-3A and MW-5. There are no regulatory standards established for these parameters. Concentrations of TOC were reported in all wells. The highest concentrations of Aggregate Organic Constituents were reported at MW-1R. These parameters were reported at concentrations consistent with previous sampling events. 7 3.5 Formaldehyde Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for formaldehyde. No concentrations of formaldehyde were detected in any monitoring wells above the method detection limits. 3.6 General Chemistry Groundwater samples collected from MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for general chemistry parameters including Alkalinity, Color, Chloride, Total Cyanide, Sulfate, Sulfide and Total Dissolved Solids (TDS). Monitoring wells MW-3B and MW-5B were sampled for TDS only. Historic data for the general chemistry parameters is presented in Table 2.  The highest alkalinity value of 373 mg/L was reported at MW-1R, which is a historic high for that parameter. Concentrations reported in the remaining wells were consistent with previous data. There are no regulatory standards for alkalinity.  Color was reported above the SMCL of 15 Color Units (C.U.) in each of the wells except MW-4A. The Color units reported are consistent with historical data.  Chloride was detected in all wells at concentrations between 20 mg/L and 63 mg/L. All of the wells reported Chloride below the SMCL of 250 mg/L. The highest chloride value was reported at monitoring well MW-3A (63 mg/L).  Total Cyanide concentrations were reported as Non-Detect in all monitoring wells.  Sulfate concentrations were reported in MW-3A and MW-5, while MW-1R and MW-4A reported Sulfate as Non-Detect. The concentrations reported in MW-3A and MW-5 were below the Secondary Maximum Contaminant Levels and consistent with historic data, as shown in Table 2. Sulfide was reported in MW-1R at a concentration of 0.09 mg/L. All of the remaining wells reported sulfide as Non-Detect. There is no standard for sulfide.  TDS concentrations were reported above the SMCL of 500 mg/L in MW-3A (530 mg/L). The remaining wells reported TDS concentrations below the SMCL and consistent with historical results. Low TDS was reported in downgradient wells MW-3B (40 mg/L) and MW-5B (31mg/L). Future groundwater testing will include TDS at the down gradient MW-3B and MW-5B locations while TDS concentrations remain elevated at upgradient locations. Groundwater samples collected from MW-1R, MW-3A, MW-4A, MW-5 were also analyzed for Total Kjeldahl Nitrogen (TKN), Nitrate, Nitrite, Total Nitrogen and Total Phosphorus. 8  Nitrate was reported in MW-4A at 3.74 mg/L, below the MMCL of 10 mg/L. All other wells reported Nitrate as Non-Detect. Concentrations of Nitrate reported are consistent with historical results and trends.  Nitrite was reported as Non-Detect (<0.05) in all wells.  Nitrogen, including Nitrate and Nitrite was reported in MW-4A (3.7 mg/L) and MW-5 (0.1 mg/L). Monitoring wells MW-1R and MW-3A reported concentrations of Nitrate/Nitrite as Non-Detect (<0.1mg/L). All of the concentrations reported were below the MMCL of 10 mg/L.  Concentrations of TKN were reported in samples from MW-1R, MW-3A, and MW-5 ranging from 5.3 mg/L in MW-3A to 9.41 mg/L in MW-1R. Concentrations of TKN in MW- 4A were reported as Non-Detect (<0.3 mg/L). There is no groundwater standard for TKN.  Total Phosphorus was detected in each of the wells sampled, with concentrations ranging from 0.036 mg/L in MW-4A to 1.2 mg/L in MW-1R. There is no state or federal groundwater standard for Phosphorus. 3.7 Field Parameters Field parameters [temperature, pH, specific conductivity, dissolved oxygen (DO) and oxidation-reduction potential (ORP)] were recorded during the May 2023 groundwater sampling event. The historical data for the field parameters are presented in Table 2.  Groundwater temperatures varied between wells, ranging from 58.0 to 67.1 degrees Fahrenheit (F). Groundwater at downgradient wells MW-3B and MW-5B reported temperatures of 58.2°F and 58.0°F, respectively. Monitoring wells MW-4A and MW-5 reported groundwater temperatures of 59.6°F to 60.1°F, respectively. While monitoring wells MW-1R and MW-3A reported temperatures of 64.0°F and 67.1°F, respectively.  Monitoring wells MW-4A, MW-5, MW-3B, and MW-5B reported pH values below the SMCL (<6.5 S.U.). The values ranged from 4.87 to 6.00 and are consistent with previous results. Monitoring wells MW-1R and MW-3A reported pH values of 6.63 and 6.51, respectively.  Conductivity readings ranged from 1,031 uS/cm to 61.9 uS/cm, with higher conductivity observed in MW-1R (1,031 uS/cm), MW-3A (704 uS/cm), and MW-5 (491 uS/cm) and lower conductivity observed in MW-4A 134.2 uS/cm), MW-3B (96.0 uS/cm), and MW-5B (61.9 uS/cm).  Dissolved oxygen (DO) concentrations ranged from 0.74 mg/L to 5.44 mg/L, with lower concentrations of DO were observed in MW-1R (0.74 mg/L) and MW-3A (0.87 mg/L), and higher concentrations noted at MW-4A (1.16 mg/L), MW-5 (1.03 mg/L), MW-3B (1.01 mg/L), and MW-5B (5.44 mg/L). 4.0 CONCLUSIONS The following is a summary of the key findings of the November 2023 groundwater monitoring event: • Total Arsenic was reported in MW -1R and MW -3A above the MA Drinking Water Standard (0.01 mg/L) and Method 1 GW-1 Risk Characterization Standard (0.01 mg/L). However, the Site is considered Adequately Regulated under the MCP, and therefore no Notification to MassDEP is required. All remaining wells, including downgradient wells MW -3B and MW -5B, reported arsenic concentrations as Non -Detect. • Various parameters (Color, pH, TDS, Total Iron and Total Manganese) were reported at concentrations exceeding SMCL and/or OSRG parameters. These findings are consistent with previous results. The low pH reported is typical and inherent to the entire Cape Cod aquifer. • Nitrate and Nitrogen (Nitrate/Nitrite) were not detected at concentrations exceeding regulatory standards at any monitoring well during this sampling event. • No PAHs were reported in any of the monitoring wells. • No VOC compounds were detected in any of the monitoring wells.

Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report. Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter (i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target Compound List, even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE", respectively. When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications. Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located at the back of the report. HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air canisters will be disposed after 3 business days from the date the project is completed. Please contact Project Management at 800-624-9220 with any questions.

Members Absent: John Keith Guests: Item 1: Update on Solar Array Project, Freemans Way – BOH approval letter for termination of the Site Assignment as part of the Landfill Closure and Post-Closure Use under DEP regulations. Amy gave a quick update because we have done a lot of work with the applicant on that as part of the solar array project. As part of the DEP approval for that site, because it did have an open landfill permit for its prior use, BOH was required to approve the site assignment. Because that landfill has now been closed, DEP, as part of the administrative process for closure of the landfill, BOH formally voted to close the site assignment that had been earmarked for that property on 12/6. They are continuing to move forward with that process through DEP to get that property developed with a new solar array project. Just FYI for everybody. They do still have monitoring wells that they will be forwarding those results to us on an annual basis. No further questions. Item 2: Discussion to prioritize upcoming topics for WQRC to review and make recommendations: a. Review and revise application and renewal process for WQRC certificates b. Continue discussion of current and future role of WQRC c. Continue discussion of Zoning Bylaw pertaining to the Water Quality Protection District, its current function, and future needs to be addressed Amy said this was derived from the conversation from our last meeting where Jon Idman, Town Planner, gave a thorough background on the zoning bylaw and how he interprets it and how the bylaw defines the role of this committee, which is narrow as it is currently written in the bylaw. It was TOWN OF BREWSTER Water Quality Review Committee 2198 Main Street Brewster, Massachusetts 02631-1898 (508) 896-3701 x1121 FAX (508) 896-8089 WQRC Meeting Minutes 12-22-2023 2 written for a reason at the time. Right now, there is a strong need to review the bylaw and figure out what needs to be revised. Bottom line, this is going to involve a much broader and higher-level policy decision with our new water quality resource taskforce and Select Board Policy decision. It is going to affect how we review certificates. This will be presented at the next taskforce meeting in January. Amy’s recommendation is to place certificates on hold for 2024 until that decision is made. Chris asked if we should vote to extend all existing permits, so they are not delinquent in the next year, or are we planning to do something different. We probably won’t solve this in the next 6 months. Amy said the way she sees it, we’ve all of 2024 to renew these. She is not concerned as she doesn’t know any that have had changes. Chris asked if it’s useful to have a Board to review these so staff aren’t under as much pressure from businesses. Amy agreed. She doesn’t think this board process would change, just the procedure for renewals. Robert asked if it was useful to think about two separate processes – special permit with change of use, versus the renewal? Chris said there have been many changes in the last few years and we are looking at many big changes coming. The original WQRC delt with the area around the wells, and that expanded to the wells on both sides of town and included the watershed from pleasant bay and the Herring River Watershed. We are going to have a much larger charge going forward. We may need to get a professional to draft it. Amy said water quality issues are not going away, it’s a matter of how we can be more efficient. We need to update how we are addressing our water quality issues. Ned said he would be comfortable holding off on renewals at this time. Robert thinks it would be a good idea to proactively let these certificate holders know that things are in flux for now and we are re-addressing this, so they don’t waste their time and effort. Ned said we will wait for some feedback from the taskforce before moving forward. Robert asked what would trigger another WQRC Meeting – it would meet on an as needed basis. Amy said we probably wouldn’t meet next until February after we get information from the taskforce. She will also look into Cape Sand and see what to do there.
