The existing area consists of a paved driveway entrance apron, a dirt/gravel driveway,grassed areas, moveable boat racks, a failed bituminous concrete boat launch that extends into the Lake, and a cobble and concrete retaining wall along the water's edge.The retaining wall is currently held up by tree roots that have grown into and around the wall and pieces of the existing asphalt boat launch have broken off into the Lake.A project locus map is provided in Appendix B. Lake Cochichewick serves as the Town's drinking water supply source. Boating on the Lake is limited to watercraft designed to be propelled manually or with the use of electric motors. The maximum length of motorized craft is 15-feet.All gasoline or diesel-powered engines, and the use or backing of trailers into lake waters, are prohibited from use on the Lake without a special permit. The Boat Launch's secondary purpose includes emergency access for the North Andover's Fire Department boat.The fire department requires access to this boat launch to respond to water- based emergencies.

In North Andover, all CPA decisions are overseen by the Community Preservation Committee (CPC). According to the Town of North Andover's website, "Watershed protection of Lake Cochichewick, North Andover's sole drinking water source, is a major priority of CPA." The Town of North Andover developed the Lake Cochichewick Watershed Plan to ensure the availability of safe drinking water. The Watershed Plan was established under the standards of the US Environmental Protection Agency and the Massachusetts Department of Environmental Protection. The Project is in line with the goals established in the Watershed Plan including improving water quality and maintaining the viability of ecological features and values of Lake Cochichewick.

The CPC meets monthly to discuss potential projects and holds one annual public forum to discuss CPA funded projects. The Proponent has submitted several project updates to the CPC throughout the preliminary design process and welcomed all Committee feedback. The Proponent held public meetings with the North Andover Conservation Commission and Planning Board to review the preliminary site design and incorporated feedback from both groups and the public into the site design. The Proponent also meets regularly with a Town Group that was specifically convened for this project.The group is made up of interested citizens of North Andover, and several specific design features have been implemented based on discussions with this group. The Project has gone through the local approval processes during which public hearings were held to discuss the Project.All public hearings required public notice and newspaper advertisement. Following a public hearing held for the North Andover Planning Board on August 27, 2024, the local newspaper,the Eagle Tribune, issued an article on August 30, 2024 summarizing the meeting and describing the proposed project and next steps. The article is provided in Appendix F of this filing. SECIITION 4 ALIITERNAIITIVES ANALYSIS The purpose of this alternatives analysis is to consider the potential environmental impacts of alternative concepts. Environmental Partners analyzed each major feature separately. Key analysis factors considered were,wildlife habitat,wetland resources, stormwater, safety, accessibility, and resiliency. 11 ONE III uuu°°u umuWA���� uuuuuu um uuumu Y&��S uuumuuu our 41111111111 umi uuuuumu uuuuumu uuuuumu uuuuumu uuuuuum uuuuumu uuuuumu • Alternative 1: Mechanically Stabilized Earth (MSE) Concrete Block Wall • Alternative 2:Vegetated Retaining Wall • Alternative 3: No-Alteration Alternative 1: Mechanically Stabilized Earth (MSE) Concrete Block Wall - consists of a modular pre- cast block retaining wall to replace the failed concrete wall adjacent to the boat launch.The block retaining wall provides long term stability and resiliency, aesthetics, shorter construction duration impacts, and is consistent with the existing wall type.Alternative 1 was the preferred option due to Lake Cochichewick's known wave-action that has caused severe erosion along its banks. Based on our analysis,we believe this Alternative will reduce maintenance and potential future wall failures, which would be more impactful to the area. Alternative 2:Vegetated Retaining- consists of a constructed mechanically stabilized earth that is vegetated with plugs, stakes, and/or seed mix. Once growth is complete,the roots prevent failure of the wall.This option provides good bank habitat. However, Lake Cochichewick's high wave-action has caused severe erosion along much of its northern bank.

Alternative 2 will not provide enough resiliency for long-term success. Furthermore, the Town does not have the maintenance capabilities to consistently maintain plantings within the wall. Alternative 3:The No-Alteration -The existing wall is currently failing. Concrete debris is visible in the Lake. If this wall is left in place, concrete will continue to fall into the Lake.A potential full failure may allow the discharge of backfill soil behind the existing retaining wall to migrate into the Lake. ISO I ............... uuumuuu 11111111111111 uuuuumu uuuuumu Y&��S Alternative 1: Rip Rap- consists of placing large stones or boulders along the slope.This method is highly effective at absorbing wave energy of and protecting the slope from further erosion. Alternative 1 was the preferred option due to Lake Cochichewick's known wave-action that has caused severe erosion along its banks, specifically in this area. Based on our analysis,we believe this Alternative will reduce maintenance and prevent future erosion to the area. Alternative 2:Vegetated Cover- consists of planting native grasses, shrubs, and trees to stabilize the soil with their root systems. This option provides good bank habitat. However, Lake Cochichewick's high wave-action has caused severe erosion along much of its northern bank. Based on our knowledge of the erosion,Alternative 2 will not provide enough resiliency for long-term success. Furthermore,the Town does not have the maintenance capabilities to consistently maintain plantings along the lake shoreline. Alternative 3:The No-Alteration -The existing erosion is significantly reducing the landmass. Concrete debris is visible in the Lake. The longer erosion is left unchecked,the more expensive and challenging it may become to implement effective solutions later. A no-action approach wouldn't be suitable here.

Permeable pavers are a good option between a soft solution and an impervious surface, such as pavement or concrete. In addition, large boulder revetment will stabilize the side slopes, offering some potential habitat. Permeable pavers combined with stone revetment will be a safe walking surface for hand carry boaters and will provide emergency access for the fire department. In addition, during the work pavement and concrete debris would be removed from the lake from the failed boat launch.This option is the preferable alternative. Alternative 2: Concrete Boat Launch with Concrete Retaining Wall - consists of cast in place or precast concrete slab with a concrete retaining wall for soil support. Concrete surfaces and walls are resilient but provide little to no environmental benefits. In addition, during the work pavement and concrete debris would be removed from the lake from the failed boat launch. iiiiumIII III;IIIIII 7 IVY111,j iur .ii IIL.... h iii III iii IIk III�,�,�,: t IIL....a t j iiri c 1i O .dlk,, ir 2024. Alternative 3: No-Alteration - Consists of the existing earthen/failed pavement at the location of the boat launch. The area does not have stable footing and is difficult to access. In addition, asphalt pavement is littered in the Lake from the failed boat launch. No cleanup would be completed in this option. 4 4 WAYS uuuuuum IIIIIIIII uuuuu uuuuumu uuum uuuuumu uuuuumu uuuuumu uuuuuum Y&���S uuuuumu • Alternative 1: Permeable Pavers • Alternative 2:Asphalt Pavement • Alternative 3: Dense Grade Gravel Alternative 1: Permeable Pavers - Consists of concrete permeable pavers with large gaps that are filled with stone, sand, or grass. This option provides is eco-friendly, low impact paving alternative to asphalt. Permeable pavers can maintain permeability,filtrate pollutants, reduce urban heat island effect, and provides long-term resiliency. Grass filled permeable pavers will denote the parking area, and stone filled pavers will denote the driveway areas.This is the preferred alternative for Driveways and Parking Areas. Alternative 2: Asphalt- Consists of a paved asphalt pavement site. Pavement is less costly but provides a resilient and safe solution for users. Pavement in impervious and will create stormwater concerns for peak flows and total suspended solids. Alternative 3: Dense Grade Gravel - Consists of a dense compacted gravel surface. Gravel surfaces are cost effective and relatively easy to maintain. The disadvantages consist of poor stormwater infiltration,yearly regrading of the site, and low resiliency. 4uuuuuum IIIIIIIII5 mu umu uuuuumu um uuum° uu mu umi uuuuuum uuuuumu uuuuumu um uuuuuum Y&���S uuuuumu • Alternative 1: Bioretention Areas • Alternative 2: Underground Stormwater • Alternative 3: No-Alteration Alternative 1: Bioretention Areas - Bioretention areas, also known as rain gardens were selected as a Best Management Practice(BMP) to treat and store stormwater runoff from a portion of Great Pond Road and the Site. The Preferred Alternative (the Project) includes two bioretention areas, an overflow structure, conveyance piping, and riprap-lined swale to manage runoff quality and quantity. Alternative 2: Underground Stormwater- Consists of underground stormwater grey infrastructure including drainage inlets, pipes, and a hydrodynamic separator to collect and treat runoff prior to discharging at an existing outfall southwest of the Site. This alternative includes additional maintenance (short term and long term)and little environmental benefits. iiiiumIII III;IIIIII8 IVY°J iur .ii IIL.... h iii III iii IIk III�,�,�,: t IIL....a t i iiri c 1i O .dlk', ir 2024. Alternative 3: No-Alteration -The No-Alteration alternative maintains existing conditions at the Project Site, leaving the untreated stormwater runoff to sheet flow towards the Lake. SECIITION 5 ENVIRONMENIITAL IMPACIITS Based on our review of 310 CM 10.00:Wetlands Protection and wetland delineation performed by Pinebrook Consulting in September 2022, a summary of the resource areas and potential impacts from the proposed work are provided in the following sections.

Lake Cochichewick is registered as a Great Pond in Massachusetts due to its size, according to a 1996 Waterways Program Study, revised through September 2017. Lake Cochichewick is also listed as an Outstanding Resource Water due to its significance as a public drinking water supply source. The Lake is the sole drinking water source in the Town of North Andover, so protection of this resource and its watershed is paramount. Lake Cochichewick is listed as a Category 5 - "Waters requiring a TMDL", in the Massachusetts Year 2022 Integrated List of Waters. Category 5 is for waters "Impaired for one or more uses and requiring a restorative action plan..."The pollutants causing the impairments in the water body are for Mercury in the fish tissue. ONE mu ME IIIIII uuuuuuuuu uuuuuum uuuuumu uuum uuuuuum um uuuuuum There are four jurisdictional wetland resources on-site regulated under WPA Regulation (310 CMR 10.00).These include a bordering vegetated wetland (BVW), inland bank to Lake Cochichewick, land under waterbody of Lake Cochichewick, and bordering land subject to flooding(FEMA Flood Zone A). All resource areas are associated with the Lake. The limits of the wetland resource areas located in and around the Project Site are shown on the Design Plans. • Inland Bank- 301 CMR 10.54:The banks were measured as the portion of land surface that occurs between a water body and upland area.The top of bank(TOB)flagging coincides with the mean high water(MHW)flagging. TOB is identified by TOB-1 through TOB-36 flag series on the Plans and in the wetland delineation sketch. The project will temporarily disturb approximately 202-linear feet of the Inland Bank associated with the North Lake Cochichewick Boat Launch Project.The work in this resource area is required to install the turbidity curtain and establish a work area to replace the existing retaining wall with a new MSE block wall from the water's edge. iiiiumIII III;IIIIII u IVY°J iur .ii IIL.... h iii III iii IIk III�,�,�,: t IIL....a t i iiri c 1i O .dlk,, ir 2024.

The physical stability of the bank along the Lake will be improved under proposed conditions. The new retaining wall extents will be located upland of the limits of the bank,the stone rock along the face of the retaining wall will be replaced, and the failing boat launch ramp will be replaced. The alteration to the Bank will not adversely impact the wildlife habitat,with the exception of conditions set forth by the Natural Heritage of Endangered Species Program (NHESP)for"Eastern Pondmussels." • Bordering Vegetated Wetland (BVW) - 310 CMR 10.55: No work is proposed within this resource area. BVW are located to the East and West of the work area, and outside of the limits of work.Work will occur within the 100-foot buffer zone of the BVW. • Land Under a Waterbody/Waterway- 310 CMR 10.56: This resource was measured as the area enclosed by the top of bank flagging. The work in this resource area is required to replace the retaining wall and stone rock along the face of the wall, construct the new boat launch ramp, and install the temporary turbidity curtain to establish the work area. The proposed work includes approximately 812 square feet of impacts to this resource area. • This resource was measured as the area enclosed by the top of bank flagging, which generally corresponds to elevation 111-feet within the project limits. The proposed activities within this resource area include installing the turbidity curtain to establish the work zone, constructing a new boat launch ramp, grading along the shoreline, and removing the existing retaining wall and stone rock along the base of the wall.The associated grading work will convert 237 square feet of upland area to land under water. This work will alter 4,838-square feet and replace 5,075 square feet of this resource area. • Bordering Land Subject to Flooding-310 CMR 10.57:This resource was measured between the top of bank flagging and the extents of the FEMA BFE (Flood Zone or Bordering Land Subject to Flooding). The proposed work occurs in the FEMA Flood Zone A. The total area of work within the resource area is 1,540 square feet.The proposed construction of the retaining wall and associated grading will have permanent impacts to BLSF. Specifically, 237 square feet of upland area will be converted to land under water body. However,this impact will be offset by the addition of 237 square feet of flood storage area in front of the proposed retaining wall. As a result,there will be no overall net change to the BLSF area.

Erosion and sedimentation control devices will be inspected daily during construction.The filter sock will control sedimentation and erosion from the upland areas and also serve to define the limits of work. The turbidity curtain shall enclose any construction activity within the Lake and sediment disturbed from dredging operations. • Stockpiles of aggregate materials(sand, gravel, and stone)will be maintained on-site as needed. The proposed stockpile location is shown on Sheet C-2 of the Design Drawings.The final location and limits of all on-site storage areas shall be reviewed and coordinated with the North Andover Conservation Commission prior to placement.Any unsuitable material excavated will be stockpiled separately of all other construction materials. All material stockpiles shall be placed on a plastic liner with hay bales or filter sock surrounding the stockpile. Disturbed areas will be limited to the areas within the limit of work.The limit of work was restricted to the maximum extent practicable.All disturbed areas will be stabilized and restored to original conditions with loam and seed after construction. Seeding of disturbed areas will be with a New England Conservation Seed Mix or similar. Loam will be low nitrogen and native to the surrounding area. • Temporary Portable Cofferdams will be installed to allow for lake draw down and for construction activities to occur"in the dry."The cofferdam structures will be installed within the Lake to allow for construction of the new boat launch and MSE retaining wall.A dewatering pump will be required to keep the work area dry. The discharged water shall pass through filter fabric, silt bags,frac tanks or a combination of all, settling out any solids prior to discharging back into the lake.

A description of the source of dredging and fill/excavation is as follows: • Dredging, as defined by 314 CMR 9.00, will be required to demolish the existing boat launch, retaining wall, and to install the slope stabilization along the Lake's edge. The total area to be dredged is approximately 812 square feet; the total volume is approximately 63 cubic yards. • Fill and excavation, as defined by 314 CMR 10.00,will occur within Land Under Water Bodies for the new boat launch, and to install the slope stabilization along the Lake's edge. The new retaining wall will be constructed inland of the Ordinary High Water (OHW) mark. No fill or excavation will take place within Bordering Vegetated Wetlands.The fill and excavation associated with these activities is anticipated to be 67 cubic yards. The dredged material will be disposed off-site in accordance with the Massachusetts Bureau of Waste Prevention (BWP) Policy#BWP-94-037, MassDEP water quality certification (WQC) of dredging projects under 314 CMR 9.00, and Interim Policy COMM-94-007: Dredged Sediment Reuse or Disposal. A Soil Management Plan (SMP) shall be submitted by the Contractor to manage excavated material that will be generated as part of the North Lake Cochichewick Boat Launch project in North Andover, MA. The SMP shall be submitted to the Owner or Engineer and/or their representative for review and approval at least three weeks prior to beginning any intrusive work at the site. The SMP shall outline measures for sampling,field screening, laboratory analysis, and disposal/off-site reuse of soils and wastes generated at the Project site. Additional soil management will be guided by the Project Specifications to be prepared by Environmental Partners as part of the final Contract Documents. It is expected that approximately 63 cubic yards of material will be dredged from Lake Cochichewick for the construction of the new hand carry boat launch, block retaining wall, and associated work. The excavated material will either be stockpiled on and covered by polyethylene sheeting, and/or directly loaded into lined and covered roll-off dumpsters and allowed to dewater. Stockpiled materials that are to be disposed of shall remain on-site for only as long as it would reasonably take to characterize, load and transport off-site to an approved disposal facility. The appropriate sediment and free water management practices shall be implemented around the stockpile/dumpsters to prevent migrations. A proposed stockpile location is shown on the Design Plans. iiiiumlll III;IIIIII 1 IV�111,j iue III°,ii IIL....aIke C h iii III iii III III�,�,�,: t IIL....a t i uri c 1i O .dlk,, ur 2024.

Minority groups comprise 40% or more of the population; 3. 25% or more of households lack English language proficiency; 4. Minority groups comprise 25% or more of the population and the annual median household income of the municipality in which the neighborhood is located does not exceed 150% of the statewide annual median household income; or 5.The Secretary has determined that a particular neighborhood should be designated as an EJ population. The Project Site is located within one mile of one block group and within five miles of an additional 110 block groups that meet the criteria of EJ populations.The block groups within five miles of the project site are primarily located in neighboring Lawrence, Massachusetts. The EJ block group located within the Designated Geographic Area ("DGA") is listed in Table 2. Per MEPA's EJ Protocol, a five-mile radius is used for Projects that will generate 150 or more daily diesel truck trips over a one-year period. The Project is not anticipated to trigger this threshold. Therefore, the analysis is focused on the Block Group with an EJ population within one mile of the Project Site.

As part of this approach, a series of mapping tools have been developed that focus on, (1)the rates of four vulnerable health criteria as it relates to statewide averages, (2) existing past and current polluting activities, (3)a review of the RMAT Climate Resilience Output Tool, (4)the use of the USEPA EJ Screen, and (5) any specific concerns raised or feedback received during pre-filing consultations from CBOs, tribes or other individuals. Each of these steps are described in detail below along with an assessment of the specific results for the EJ populations within the DGA. Section 8A.1 Vdknerable „ i ��„�Heal'th The vulnerable health Ei criteria are four environmentally related health indicators to identify populations with evidence of higher-than-average rates of environmentally related health outcomes. Multiple terms are used to describe the vulnerable health EJ criteria as it relates to the EJ populations.These terms are defined and described below. iiiiumIII III;IIIIII26 IVY°J iur .ii IIL.... ke C h iii III iii III III�,�,�,: t IIL....a t i iiri c 1i O dlk', ir 2024. The MA DPH EJ tool provides information on four different vulnerable health EJ criteria: heart attack hospitalizations, childhood blood lead exposure, low birth weight, and childhood asthma for the most recent five-year period of available data. It should be noted that each of these datasets are available at different geographies, heart attack hospitalizations and childhood asthma are available at the community level,while low birth weight and childhood blood lead exposure are available at the census tract level. Each of these specific criteria, reported by census tract, are described below along with the results of the analysis for the designated geographic area. 8.4.1 .1 ��H e a r1t Att a C��k, ��H 0 S P��i t µ m s It was found that the heart attack rate for North Andover is 25.6 per 10,000 individuals.This is less than 110% of the state-wide heart attack rate of 28.7 per 10,000. North Andover, at the community level, does not meet the Vulnerable Health Criteria for heart attack rate. 8A.1 .2 Elevat alence 110% of the state-wide rate for elevated blood lead levels between 2017-2021 was 15 per 1,000 individuals.At the community level, North Andover's blood lead level rate of 6.3 cases per 1,000 is less than 110% of the state-wide rate. The childhood blood lead level is considered stable and is lower than the state-wide level. North Andover, at the community level, does not meet the Vulnerable Health Criteria for elevated blood lead prevalence. 8A.1 . 'i Weight 110% of the state-wide rate for low birth weight was 238.5 per 1,000 individuals between 2011-2015. North Andover's community-level rate is 196.6 per 1,000,which is below the state-wide average. North Andover does not meet the Vulnerable Health Criteria for low birth weight. 8.4.1 .4. C The childhood asthma indicator is available on a community level. It was found that the childhood asthma rate for North Andover is 21.7 per 10,000 individuals.This rate is significantly less than 110% of the state-wide childhood asthma rate of 72.5 per 10,000. North Andover, at the community level, does not meet the Vulnerable Health Criteria for childhood asthma. 8.4.1 .5 VL.ikrierable Healtlh Crlteri�a SUrnrriary Based on the information described above, Norwood does not meet any of the vulnerable health criteria. Based on the descriptions provided above,the EJ communities in the designated geographic area are not considered vulnerable and are not subject to existing environmental burdens.

MassDEP Major Air and Waste Facilities MassDEP major air and waste facilities are facilities that have air operating permits, treat, store, generate or recycle large quantities of hazardous waste, or utilize large quantities of toxics.These facilities are further specified in the following sections and include airports, facilities with air permits, draft NPDES permits, hazardous waste,treatment, storage, recycling, or disposal facilities, large quantity generators, large quantity toxic users, land disposal of solid waste, and toxics release inventory sites.' Within a one-mile radius of the Project Site,there is one facility with an air operating permit. This is not located within an EJ block group boundary. There is one large quantity generator within the EJ block group boundary that is partially located within one mile of the project site. However,the generator itself is not located within one mile of the project site. M.G.L. c. 21 E Sites 21 E Sites are sites that have experienced a release of a hazardous material above a certain threshold. Once a release is reported to MassDEP it must be cleaned up within a year or it is classified as Tier I,Tier ID, or Tier II.A Tier I site poses an immediate hazard, a Tier 1 D site has not posed a permanent solution or final classification of the site while a Tier II site does not meet the criteria for an immediate hazard. There is one 21 E site (Tier 1 D)within a one-mile radius of the Project Site. This is not located within an Ei block group boundary. Tier 11 Facilities A facility is required to submit a Tier II report to emergency response agencies if it uses over a certain threshold of hazardous chemicals during calendar year. The purpose of Tier reports is to help facilitate emergency response in the event the fire department would need to respond to an emergency at the facility. Within a one-mile radius of the Project Site,there is one Tier II facility.This is not located within an EJ block group boundary. There is one Tier II facility within the EJ block group boundary that is partially located within one mile of the project site. However,the Tier II facility itself is not located within one mile of the project site. MassDEP Sites with AULs An Activity Use Limitation ("AUL") provides notice of the presence of oil and/or hazardous material contamination remaining at the location after a cleanup has been conducted pursuant to Chapter 21 E and the MCP.The AUL is a legal document that identifies activities and uses of the property that may and may not occur, as well as the property owner's obligation and maintenance conditions that must be followed to ensure the safe use of the property.

There are two facilities with AULs located within one mile of the Project Site. Neither of these facilities are located within an EJ block group boundary.The Project will not impact these AULs in a manner that adversely impacts EJ populations with the Designated Geographic Area. MassDEP Groundwater Discharge Permits This dataset contains the locations of permitted discharges of groundwater.This includes discharges from: Sanitary sewage more than 10,000 gallons per day(gpd), coin operated laundromats, car washes, industrial facilities, and reclaimed water(used in cooling towers and other closed-loop systems, no actual discharge). There were no identified MassDEP Groundwater Discharge Permits identified within one mile of the Project Site. Wastewater Treatment Plants The MA DPH tool provides information on facilities that have received a National Pollutant Discharge Elimination System ("NPDES") permit. NPDES is a permit for facilities that treat wastewater. There are no facilities located within one mile of the Project Site that hold a draft or final NPDES permit. MassDEP Public Water Suppliers This dataset contains locations of public community surface and groundwater supply sources based on data available in the DEP's Water Quality Testing System database for tracking water supply data. A community water system refers to the public water system which services at least 25 year-round residents. There are no MassDEP Public Water Suppliers within a one-mile radius of the project site. Underground Storage Tanks The MassDEP regulates the registration, installation, operation, maintenance, inspection, and closure of petroleum fuel and hazardous substances of underground storage tank(UST) systems. There are two USTs located within one mile of the Project Site. Neither of these USTs are located within an EJ block group boundary. The Project is not proposed to maintain an underground storage tank as a part of this Project. EPA Facilities EPA facilities are defined as Toxic Release Inventory("TRI")facilities.TRI facilities use and/or release over a certain threshold of toxic chemicals to the environment. There are 777 individual chemicals and 33 chemical categories covered by the TRI program.2 There are no EPA Facilities within one mile of the Project Site. 2 https://enviro.epa.gov/facts/tri/ef-facilities/#/Facility/01082KNZKS2000M iiiiirmIII III;:IIIIII29 IVY111�i iue .ii IIL.... h iii III iii IIk III�,�,�,: t IIL....a t i iiri c 1i O .dlk', ir 2024. Road Infrastructure The Project Site is located off Great Pond Road, which is a Massachusetts Department of Transportation ("MassDOT") State Road. No changes are proposed to Great Pond Road as a part of the Project. MBTA Bus and Rapid Transit The Massachusetts Bay Transit Authority data includes all MBTA bus routes, stops, commuter rails, commuter rail stations, parking lots, and rapid transit stops. There are no public transit stations or infrastructure within a one-mile radius of the Project Site. Other Transportation Infrastructure Other transportation infrastructure includes airports, freight yards, water taxis, railroad tracks, and ferry routes.There are no freight yards,water taxis, or ferry routes within one mile of the Project Site. One railroad track exists within the EJ block group within a one-mile radius of the Project Site. The Lawrence Municipal Airport is partially located within a one-mile radius of the Project Site. The proposed Project is not anticipated to impact the railroad track or airport in any way as a part of this Project. Regional Transit Agencies There is one Merrimack Valley RTA stop within one mile of the Project Site. Energy Generation and Supply The Energy Generation and Supply layer includes nuclear power plants, power plants, and transmission lines from Massachusetts Geographic Information Systems (MassGIS)and the United States Geological Survey(USGS) databases.There are transmission lines localized for energy supply within the Lawrence Regional Airport located within one mile of the Project Site. Sectilon 8.43 Cklma,te Ada p,ta,tiion (IRMAT) The state's RMAT Tool provides the proposed Project with information about sea level rise/storm surge, heat, and extreme precipitation impacts. The RMAT Tool results in Appendix F denote the proposed Project would be considered "High" risk for: Extreme Precipitation - Urban Flooding, Extreme Heat, and Extreme Precipitation - Riverine Flooding. However,there are inaccuracies in the tool due to its reliance on MassGIS data. Based on the design information,the Project is not at risk for riverine flooding. Sectioli"i 18.4.4, USEPA EJ Screen As described in the MEPA Interim Protocol for Analysis of Projects Impacts on Environmental justice Populations the next step of the existing environmental burden analysis focuses on using the USEPA EJ Screen.The USEPA EJ Screen tool was run with the"compare to state"option turned on, and the "EJ Index"data layer turned off,for the EJ community within one-mile of the Project Site. iiiiumIII III;IIIIII30 IVY111�j iue .ii IIL.... h iii III iii IIk III�,�,�,: t IIL....a t i iiri c 1i O .dlk,, ir 2024. The EJ block group was less than the 50-percentile value for the following indicators: Particulate Matter 2.5 • Ozone • Air Toxics Cancer Risk • Air Toxics Respiratory HI • Toxic Releases to Air Traffic Proximity • Lead Paint Compared to state data, the EJ block group was above the 50 percentiles for the following indicators: • 60-70 percentile Diesel Particulate Matter • 60-70 percentile Superfund Proximity • 70-80 percentile RMP Facility Proximity • 60-70 percentile Hazardous Waste Proximity • 60-70 percentile UST • 70-80 percentile Wastewater Discharge The EJ block group does not exceed the 80 percentiles for any USEPA indicators.

It does not change the current land use and is not expected to incur any adverse effects on the environment or to the surrounding communities. The proposed Project does not result in targeted disproportionate effects to the EJ block groups within the DGA. When compared to the non-EJ communities in the surrounding area - an appropriate comparable population due to proximity, geography, and shared infrastructure - it is seen that: 1) While there are several existing MassDEP-regulated facilities near the Project Site,these facilities are compliant with regulations, do not present a risk, and do not occur in numbers that indicate a targeted approach to locating such facilities. 2) traffic during construction and daily operation associated with the Project will primarily be routed along Great Pond Road and not within residential areas located in close proximity. The traffic will generally avoid direct impacts to the EJ block groups within one-mile of the Project Site. 8IIIIIIIIII 11111111111111� IIIIIIIIII IIIIIIIIII III 11111111111111� IIIIIIIIIIIIIII IIIIIIIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIIIIIIII IIIIIII IIIIIIIIIIIIIII IIIIIIIIII IIIIIIIII IIIIIIIIIIIIIII IIIIIIIIIIIIIII IIIIIIIIIIIIIII IIIIIIIIII IIIIIIIIII 11� 1111111� (IIIII IIIIIIIIIII IIII IIIIIIIIIII (IIIIIIIIIII IIIIIIIIII IIIIIIIIIII IIIII IIIIIIIIIII IIII IIIIIIIIIIII IIIIIIIIIIII IIIIIIIIII uuuuuum loom IIIIIIIII uuuuumu uuuu uuuuumu uuuuuum %) IIIN uuuuumu uuuuumu uuuuumu uuuuuu uuuuuum uuuuuum ou In addition to analyzing adverse impacts, a proponent should analyze any project benefits that improve environmental conditions or the public health of the EJ population, or otherwise reduce the potential for unfair or inequitable effects on the EJ population. Emphasis should be given to project benefits that are intended to reduce any existing environmental burdens or public health iiiiumIII III;(IIIII31 Ili°'J r III°�ii IIL....

The Project is not expected to directly or indirectly, cause damage to the environment which would affect the identified Ej populations.There will be temporary impacts associated with construction including construction traffic and noise.The Project does not exceed any MEPA thresholds for a mandatory Environmental Impact Report, relative to the thresholds for wastewater(301 CMR 11.03(5)), air emissions (11.03(8)), and solid and hazardous waste (11.03(9)). The Project is expected to provide benefits to the Ej populations located within one mile of the Project Site. Project Benefits include the following: • Increase pedestrian area safety-The proposed boat launch project will include a new hand carry boat launch at a suitable grade of 12.5%for pedestrian access. The new retaining wall will include a safety railing that is consistent with current building code. The driveways and walkways will allow good walking surfaces.All of these design features will mitigate site safety to falls and other pedestrian accidents. • Increased vehicular safety-The proposed boat launch will include a one-way driveway and parking spaces with adequate turnaround capabilities. This will allow for additional vehicle safety. • Emergency access improvements -The boat launch has been designed for fire department access to the Lake for water emergencies by including collapsible bollard to allow for their trailer mounted boat quick access. In addition, driveway turning radii will allow fire department vehicles access and the ability to drive-thru the site. • The beneficial impacts to Ej population include the following: o A net decrease in impervious area on the Property of at least 5,000 square feet through replacement of packed gravel with permeable pavers; o New and improved stormwater management facilities,which are designed to increase groundwater recharge, reduce scour to North Lake Cochichewick, and enhance water quality of this public drinking water source relative to existing conditions; o Increase the total area of land under waterbody, increasing the size of the resource area and enhancing benefits associated with the resource area; o Improved community access to North Lake Cochichewick via the new public hand carry boat launch. o Improve Lake access for emergency vehicles and Fire Department water access. • Stormwater treatment improvements -The project will include two stormwater bioretention areas, and pervious pavers. This will be a general improvement over existing conditions. iiiiumIII III;IIIIII32, IVY111�j iue .ii IIL.... h iii III iii IIk III�,�,�,: t IIL....a t i iiri c 1i O .dlk,, ir 2024. uuuuX A ii�st r,'i��b ut'i��o ri 'i��st MEPA DISTRIBUTION LIST Massachusetts Environmental Policy Act(MEPA)Office Email: MEPA@mass.gov MEPA Office 100 Cambridge Street, Suite 900 Boston, MA 02114 Department of Environmental Protection, Boston Office Email: helena.boccadoro@mass.gov .................................................................................................................................................................................Commissioner's Office One Winter Street Boston, MA 02108 MassDEP Northeast Regional Office Email:jQbDAyjQja@maaaZQv DEP/Northeast Regional Office Attn: MEPA Coordinator 150 Presidential Way Woburn, MA 01801 Massachusetts Department of Transportation - Boston Email: MassDOTPPDU@dot.state.ma.us .................................................................................................................................................Public/Private Development Unit 10 Park Plaza, Suite#4150 Boston, MA 02116 Massachusetts Department of Transportation - District#4 Office Email:timoth.........�paris@dot.state.ma.us MassDOT District#4 Attn: MEPA Coordinator 519 Appleton Street Arlington, MA 02476 Massachusetts Historical Commission *Hard Copy Only* The MA Archives Building 220 Morrissey Boulevard Boston, MA 02125 EEA Environmental justice Director Email: l EP E( mas s® �ov .........................................................................

Sea Level Rise/Storm Surge This project received a "Not Exposed" because of the following: • Not located within the predicted mean high water shoreline by 2030 • No historic coastal flooding at project site • Not located within the Massachusetts Coast Flood Risk Model (MC-FRM) Extreme Precipitation- Urban Flooding This project received a "High Exposure" because of the following: • Historic flooding at the project site • Maximum annual daily rainfall exceeds 10 inches within the overall project's useful life • No increase to impervious area • Existing impervious area of the project site is between 10%and 50% Extreme Precipitation- Riverine Flooding This project received a "High Exposure" because of the following: • Part of the project is within a mapped FEMA floodplain,outside of the Massachusetts Coast Flood Risk Model(MC-FRM) • Part of the project is within 100ft of a waterbody • Project is potentially susceptible to riverine erosion • No historic riverine flooding at project site Extreme Heat This project received a "High Exposure" because of the following: • 30+ days increase in days over 90 deg.F within project's useful life • Existing trees are being removed as part of the proposed project • Existing impervious area of the project site is between 10%and 50% • Located within 100 ft of existing water body • No increase to the impervious area of the project site Scoring Rationale - Asset Preliminary Climate Risk Rating A Preliminary Climate Risk Rating is determined for each infrastructure and building asset by considering the overall project Exposure Score and responses to Step 4 questions provided by the user in the Tool. Natural Resource assets do not receive a risk rating.The following factors are what influenced the risk ratings for each asset.

Engineers on the project painted a picture of where the project stands and what users can expect of the hand-carry boat launch when completed during the Planning Board meeting Monday. The project is in its design phase.Environmental Partners,engineers who represent the town,have also applied for a watershed special permit. The Community Preservation Committee is funding the boat launch's restoration and construction.Voters approved the cost for the boat ramp's restoration during town election. The new hand-carry boat launch will be constructed,along with a mechanically stabilized earth concrete block retaining wall,paved driveway and parking lots and recreational lawn space,in addition to an updated stormwater management system.The current boat launch will be demolished. Director of Planning Jean Enwright said the project has been phased in over the last few years. Jamie Veillette,a senior project engineer at Environmental Partners,presented the updates to the Lake Cochichewick Lake boat launch project which is in the design stage. She went before the Planning Board nearly two years ago when the project was in its preliminary stages. Veillette discussed how the current boat launch and retaining wall are in disrepair. The proposed plan includes a new layout to have the boat racks closer to the boat launch. This will reduce the walk to get to the ramp and help pedestrians stay as they will no longer be crossing through the gravel,Veillette said. The area under the boat rack will have grass instead of gravel. The boat launch's slope will not be as steep, increasing safety for those using it,the engineer added. Engineers have additionally updated where the FEMA flood zone line will be and moved the retaining wall 2 feet inland to reduce any impacts to the flood zone. A new traffic pattern will be established at the site with a circular driveway.Accessible parking and spaces for trailers are planned,along with a walkway to get to the boat launch from the parking area. The trailer parking has been added to accommodate those with hand-carry boats,kayaks and canoes. Planning Board member Peter Boynton said this is a tremendous improvement for the site and applauded the move to have the racks close to the hand carriers. At this time,there are no plans for a sidewalk on Great Pond Road or any lighting fixtures related to this project. The public hearing on the boat launch will continue Sept. 10.A peer review regarding the stormwater system is planned to be discussed. a ir e S e c i s w i�("I i-f'e, inr",iatiurii " - DIVISION OF r FISHERIES & WILDLIFE 1 Rabbit Hill Westborough,a , ;1I 15 " -(508)1389---6300 f-(508)1389_-7890 AWIILLIFE March 15,2024 Jamie Veillette Environmental Partners Group,LLC 1900 Crown Colony Drive,Suite 402 Quincy,Massachusetts 02169 RE: Applicant: Jamie Veillette Project Location: Great Pond Road Project Description: North Lake Cochichewick Boat Launch NHESP File No.: 24-17147 Dear Applicant: The Natural Heritage&Endangered Species Program of the Massachusetts Division of Fisheries&Wildlife(the "Division")received the MESA Project Review Checklist and supporting documentation for review pursuant to the Massachusetts Endangered Species Act(MESA)(MGL c.131A)and its implementing regulations(321 CMR 10.00).

On behalf of the Town of North Andover, Environmental Partners is submitting this due diligence review and sampling analysis plan (SAP) in support of the Lake Cochichewick Boat Launch project located in North Andover, Massachusetts. 1 The project generally consists of the reconstruction of the existing boat launch,which has fallen into disrepair, a new mechanically stabilized earth (MSE) concrete block retaining wall to replace the existing concrete and cobble retaining wall, and rip rap slope stabilization adjacent to the wall. The project does not trigger any 401 Water Quality Certification (WQC)thresholds except that it is within an outstanding resource water. The purpose of the sampling described in this plan is to collect sediment quality data to support 401 WQC application and the development of a Sediment Management Plan. The due diligence review and sampling analysis plan (SAP) is attached for your review.The SAP was developed in general accordance with the Massachusetts Department of Environmental Protection (MassDEP)401 WQC regulations, 314 CMR 9.00. We estimate the dredging of approximately 51 cubic yards for the new boat ramp and retaining wall within Lake Cochichewick(an Outstanding Resource Water). In accordance with the 401 WQC dredge material sampling and analysis requirements outlined at 314 CMR 9.07(2)(b), one sample core should be collected and characterized physically and chemically for every 1,000 cubic yards of proposed dredge material for projects up to 10,000 cubic yards,with a minimum of two samples collected.Therefore,we propose two samples; located at the boat launch, where the majority of work will occur.The samples shall be collected 3-ft below existing grade,which is the proposed maximum dredge depth. The two samples will be analyzed for parameters listed in 314 CMR 9.07(2)(b)6. No additional parameters are anticipated to be sampled for at this time. Additionally,we've completed a due diligence review of publicly available records associated with the Project area and the general surrounding area. This review was performed to determine the potential for contamination in the dredged material.The due diligence review consists of current and past land uses of the surrounding area in addition to documents obtained from the Bureau of Waste Site Cleanup and the Massachusetts Department of Environmental Protection. A review of the land use and documentation showed nearby properties with open waste cleanup activities. The Town's 2021 Lake Cochichewick Watershed Plan was also reviewed for any other pertinent information to potential contaminants in the vicinity that could impact the sediment.The Watershed Plan includes a comparison of water quality data from 1986 vs. 2021 showing a general increase in the Lake's ecological health. Please refer to attachment 2 for files associated with the due diligence review. Please let me know if the sampling plan (provided in attachment 1) is acceptable and we'll proceed with sampling prior to submitting the 401 WQC application.

The Proponent also requested that, if a rollover EIR were not granted, a Single EIR be allowed to be submitted in accordance with 301 CMR 11.06(8) in lieu of the usual two-stage Draft and Final EIR process. In light of the fact that a Proposed EIR was not included the submittal, I am denying the rollover request. In accordance with Section 11.06(8) of the MEPA regulations, I hereby grant the request to file a Single EIR, which the Proponent should submit in accordance with the Scope included in this Certificate. Project Description As described in the EENF, the Town of North Andover proposes site improvements at the existing boat ramp located on Great Pond Road. These improvements include the demolition of the existing paved boat launch, cobble and concrete retaining wall, and gravel parking area. The project includes the construction of a new hand-carry boat launch, a Mechanically Stabilized Earth (MSE) block wall, and permeable paver parking areas and a paved driveway apron. Additionally, two bioretention areas will be installed to manage stormwater, along with tree EEA# 16850 EENF Certificate August 16, 2024 plantings. Security measures will include a double swing gate with locking bollards at the boat launch entrance to restrict access when the boat launch area is closed. Project Site The 0.74-acre project site is located on the north side of Lake Cochichewick' (the lake) on a parcel along Great Pond Road owned by the Town of North Andover(the Town). The site is situated across from 1939 Great Pond Road, in an area formerly occupied by the Town's North Sewer Pump Station, which was previously demolished and removed. The existing site includes a boat launch with a dirt/gravel driveway, boat racks, a deteriorating bituminous concrete launch extending into the lake, and an old cobble and concrete retaining wall along the lake's edge. Wetland resource areas present in the vicinity of the project area include Boarding Vegetated Wetlands (BVW) Inland Bank (Bank), Land Under Waterbodies and Waterways (LUWW), and Bordering Land Subject to Flooding (BLSF). The North Lake Cochichewick Boat Launch project will occur within the mapped Estimated or Priority Habitat of Rare Species as delineated by the Natural Heritage and Endangered Species Program (NHESP) in the 15th Edition of the Massachusetts Natural Heritage Atlas. The Massachusetts Historical Commission (MHC) has determined that the project is unlikely to affect significant historic or archaeological resources listed in the State Register of Historic Places or the MHC's Inventory of Historic and Archaeological Assets of the Commonwealth. According to supplemental information submitted electronically on August 13, 2024 by Jaimie Veillette the proposed work is situated in a FEMA Flood Zone (FEMA Flood Zone A) where a specific Base Flood Elevation (BFE) has not been determined. The project is located within an Outstanding Resource Water(ORW), specifically Lake Cochichewick, which serves as the Town's drinking water supply. Lake Cochichewick is an impaired water body for mercury in fish tissue. The project site is within one mile of an Environmental Justice (EJ) population characterized as Minority in the town of North Andover. The site is also located within five miles of multiple EJ Populations characterized as Minority, Minority and Income, Minority and English Isolation, and Minority, Income and English Isolation, in the towns of Haverhill, Lawrence, Methuen, and North Andover. There are no languages spoken by 5% or more of residents within the EJ populations located within a 1-mile radius of the project site. As described below, the EENF identified the "Designated Geographic Area" (DGA) for the project as one mile around EJ Populations, included a review of potential impacts and benefits to the EJ Populations within this DGA, and described public involvement efforts undertaken to date. Environmental Impacts and Mitigation Potential environmental impacts associated with the project include the alteration of 202 linear feet(If) of Bank, 594 square feet (sf) of LUWW, and 28,148 sf of BLSF. In addition, the project will include 63 cubic yards (cy) of improvement dredging. 1 Lake Cochichewick is identified in the current"Massachusetts Great Ponds List"document available at www.mass.gov. 310 CMR 9.02 defines a great pond as"any pond which contained more than ten acres in its natural state, as calculated based on the surface area of lands lying below the natural high-water mark." 2 EEA# 16850 EENF Certificate August 16, 2024 Measures to avoid, minimize, and mitigate environmental impacts include a proposed stormwater management system with two bioretention areas (rain gardens), designed to increase groundwater recharge, reduce scour to Lake Cochichewick, and improve water quality. Prior to the initiation of work, a search will be conducted by a biologist approved by the Massachusetts Division of Fisheries & Wildlife for state-listed mussels, and mussels found during the search will be moved out of areas that will be altered through the project. The project will also increase the total area of land under the waterbody by removing the existing boat launch and constructing the new boat launch and alterations to the bank needed to install the new MSE block wall, expanding the resource area. According to the EENF, the project includes a net decrease in impervious area of at least 5,000 square feet through replacement of packed gravel with permeable pavers. Construction-period mitigation measures will include the use of erosion and sediment controls, a turbidity curtain, and a cofferdam. Traffic during construction and daily operation associated with the project will primarily be routed along Great Pond Road and not within residential areas located in close proximity. According to the EENF, the traffic will generally avoid direct impacts to the EJ block groups within one mile of the project site. Jurisdiction and Permitting This project is subject to MEPA review and the preparation of an ENF pursuant to 301 CMR 11.03 (3)(b)(1)(c) of the MEPA regulations because it requires Agency Action and will result in the alteration of 1,000 or more sf of salt marsh or outstanding resource waters. The project will require a Combined Chapter 91 License & 401 Water Quality Certification from the Massachusetts Department of Environmental Protection (MassDEP), a Massachusetts Endangered Species Act(MESA) Project Review by NHESP, and submittal of a Project Notification to the Massachusetts Historical Commission(MHC). The project will apply for an Order of Conditions (OOC) from the North Andover Conservation Commission; in the case of an appeal, a Superseding Order of Conditions from MassDEP will be required. The project will also require the submittal of aPre-Construction Notification(PCN) to the U.S. Army Corps of Engineers (ALOE) seeking authorization under the General Permits for Massachusetts in accordance with Section 404 of the Clean Water Act. Because the project is not seeking Financial Assistance from an Agency, MEPA jurisdiction for any future reviews would extend to those aspects of the project that are within the subject matter of required or potentially required permits, and that are likely, directly or indirectly, to cause Damage to the Environment. Request for a Rollover EIR or Single EIR The EENF included a request that I allow a Rollover EIR in accordance with 301 CMR 11.06(9) or alternatively, a Single EIR in accordance with 301 CMR 11.06(8). The MEPA regulations provide that for projects required to submit an EIR under 301 CMR 11.06(7)(b), the Proponent may submit an EENF/Proposed EIR with a request that I allow a Rollover EIR in accordance with 301 CMR 11.06(13). To support this request, the EENF must be accompanied by a Proposed EIR, which, if the request for Rollover EIR is granted, would be published as a Final EIR in a subsequent Environmental Monitor in lieu of the typical two-stage Draft and Final EIR process. 3 EEA# 16850 EENF Certificate August 16, 2024 In order to allow a Rollover EIR, I must find that the dual EENF and Proposed EIR: a. presents a complete and definitive description and analysis of the project and its alternatives, and an assessment of its potential environmental and public health impacts and mitigation measures sufficient to allow a Participating Agency to fulfill its obligations in accordance with M.G.L. c. 30, §§ 61 and 62K and 301 CMR 11.12(5) b. demonstrates that the project will not materially exacerbate any existing unfair or inequitable Environmental Burden and related public health consequences impacting an EJ population, and will not result in a disproportionate adverse effect or increased climate change effects on an EJ Population c. describes measures taken to provide meaningful opportunities for public involvement by EJ Populations prior to filing the dual ENF and Proposed EIR, including any changes made to the project to address concerns raised by or on behalf of EJ Populations d. shows that comments received on the dual ENF and Proposed EIR do not raise substantial issues not previously considered by the Proponent The MEPA regulations indicate that a Single EIR may be allowed provided I find that the EENF: a. describes and analyzes all aspects of the project and all feasible alternatives, regardless of any jurisdictional or other limitation that may apply to the Scope; b. provides a detailed baseline in relation to which potential environmental impacts and mitigation measures can be assessed; and, c. demonstrates that the planning and design of the project use all feasible means to avoid potential environmental impacts. To support a Single EIR request for any Project for which an EIR is required in accordance with 301 CMR 11.06(7)(b), I must also find that the EENF: d. describes and analyzes all aspects of the Project that may affect EJ Populations located in whole or in part within the Designated Geographic Area around the project; describes measures taken to provide meaningful opportunities for public involvement by EJ Populations prior to filing the EENF, including any changes made to the project to address concerns raised by or on behalf of EJ Populations; and provides a detailed baseline in relation to any existing unfair or inequitable Environmental Burden and related public health consequences impacting EJ Populations in accordance with 301 CMR 11.07(6)(n)(1) Consistent with this request, the EENF was subject to an extended comment period under 301 CMR 11.05(7). As noted, for any project that is required to file an EIR in accordance with 301 CMR 11.06(7)(b), and has submitted a dual Expanded ENF and Proposed EIR in accordance with 301 CMR 11.05(9), the Secretary may allow a rollover EIR. However, as no Proposed EIR was included in the submittal, I am denying the request to treat this EENF filing as a rollover FEIR. For the reasons stated below, I hereby grant the request to file a Single EIR. 4 EEA# 16850 EENF Certificate August 16, 2024 Review of the EENF The EENF provided a project description, alternatives analysis, existing and proposed conditions plans, estimates of project-related impacts, a Stormwater Report and identification of measures to avoid, minimize and mitigate environmental impacts. It included a description of measures taken to enhance public involvement by EJ Populations and baseline assessment of any existing unfair or inequitable Environmental Burden and related public health consequences impacting EJ Populations in accordance with 301 CMR 11.07(6)(n)l.). Consistent with the MEPA Interim Protocol on Climate Change Adaptation and Resiliency, the EENF contained an output report from the Climate Resilience Design Standards Tool prepared by the Resilient Massachusetts Action Team (RMAT) (the "MA Resilience Design Tool"),2 together with information on climate resilience strategies to be undertaken by the project. Alternatives Analysis The EENF evaluated a range of alternatives to achieve the proj ect's objectives of providing a functional and long-lasting hand-carry boat launch site for community use, enhancing the area's environmental sustainability, and aesthetic appeal, and maintaining emergency access for the North Andover Fire Department while minimizing environmental impacts. The EENF evaluated the following alternatives: Alternative 1: Boat Launch w/LID Elements, Alternative 2: Concrete Boat Launch, Alternative 3: No Action. Alternative 1, the (Preferred Alternative), entails comprehensive site redevelopment, including the reconstruction of the boat launch ramp and the replacement of the existing retaining wall with a new Mechanically Stabilized Earth (MSE) concrete block wall. This alternative also features enhanced parking areas and driveway access, recreational lawn space, and the installation of two bioretention areas. The redevelopment incorporates Low Impact Development (LID) elements, such as native plantings in the bioretention areas and permeable pavers for the new ramp, driveways, and parking lot. Additionally, a curved block wall will be installed in a curvilinear layout to follow the natural contours of the water's edge. According to the EENF, this approach aims to replace the existing failed boat launch, replace the failed concrete and stone retaining wall along Lake Cochichewick, re-organize the parking, driveway, and boat rack areas, as well with LID elements to reduce stormwater runoff volumes and minimize pollutants introduced from impervious areas, thereby helping to restore the watershed's ecological functions and improve water quality. Alternative 2 involves the replacement of the failed boat launch with a new concrete ramp and an in-kind concrete-stone retaining wall along the shoreline. This alternative also proposes the construction of a new paved parking lot and driveway. The layout of the parking and driveway features remains the same between Alternatives 1 and 2, with the primary distinction being the material selection for the parking lot, driveway, boat ramp, and retaining wall. Unlike Alternative 1, which incorporates Low Impact Development (LID) elements, Alternative 2 uses traditional concrete and pavement, maintaining a conventional approach to infrastructure development which would result in greater stormwater runoff, with potential erosion and transport of pollutants into the lake Therefore, this alternative was dismissed. 2 Available at: https:Hresilientma.mass.gov/rmat_home/designstandards/ 5 EEA# 16850 EENF Certificate August 16, 2024 Alternative 3, the No Action Alternative, would maintain existing conditions at the project site, leaving the failing boat launch in place. Although this alternative would not result in any new impacts, it would not advance the proj ect's goal of replacing the existing failed boat launch, failed concrete and stone retaining wall, nor would it provide other benefits inherent to the proposed redevelopment, such as the incorporation of stormwater best management practices (BMPs) into the upland site. For this reason, Alternative 3 was not selected. Environmental Justice (EJ)/Public Health As noted above, the project site is within one mile of one (EJ) population characterized as Minority. There are numerous additional EJ populations located within 5 miles of the project. Within the census tracts containing the above EJ populations within 1 mile of the project site, there are no languages spoken by 5% or more of residents who also identify as not speaking English very well (Limited English Proficiency (LEP) individuals). The EENF indicates that the DGA for the project is 1 mile. Effective January 1, 2022, all new projects in"Designated Geographic Areas" ("DGA," as defined in 3 01 CMR 11.02, as amended) around EJ populations are subj ect to new requirements imposed by Chapter 8 of the Acts of 2021: An Act Creating a Next-Generation Roadmap for Massachusetts Climate Policy (the "Climate Roadmap Map") and amended MEPA regulations at 301 CMR 11.00. Two related MEPA protocols the MEPA Public Involvement Protocol for Environmental Justice Populations (the "MEPA EJ Public Involvement Protocol") and MEPA Interim Protocol for Analysis of project Impacts on Environmental Justice Populations (the "MEPA Interim Protocol for Analysis of EJ Impacts") are also in effect for new projects filed on or after January 1, 2022. Under the new regulations and protocols, all projects located in a DGA around one or more EJ populations must take steps to enhance public involvement opportunities for EJ populations, and must submit analysis of impacts to such EJ populations in the form of an EIR. The EENF describes public involvement activities conducted prior to filing, including advance notification of the project circulated to a list of community-based organizations (CBOs) and tribes/indigenous organizations (the "EJ Reference List") provided by the MEPA Office. Information circulated by the Proponent included the EJ Screening Form which identified who to contact in order to request a meeting with the Proponent. According to the EENF, the Proponent held public meetings with the North Andover Conservation Commission on November 16, 2022, Planning Board on December 6, 2022, and the North Andover Community Preservation Committee, on February 8, 20243 to review the preliminary site design and incorporated feedback from both groups and the public into the site design. The Proponent also meets regularly with an informal town group of interested residents of North Andover, and several specific design features have been implemented based on discussions with this group. Baseline Conditions and Project Impacts The EENF contains a baseline assessment of existing unfair or inequitable Environmental Burden and related public health consequences impacting EJ populations in accordance with 301 CMR 11.07(6)(n)I and the MEPA Interim Protocol for Analysis of EJ Impacts. The EENF 3 Supplemental information received electronically from the Proponent's consultant on August 16,2024 identified the dates the proponent held these public meetings. 6 EEA# 16850 EENF Certificate August 16, 2024 indicates that North Andover does not meet any"vulnerable health EJ criteria"; this term is defined in the DPH EJ Tool to include any one of four environmentally related health indicators that are measured to be 110% above statewide rates based on a five-year rolling average.4 In addition, the EENF indicates that the following sources of potential pollution exist within the identified EJ populations, based on the mapping layers available in the DPH EJ Tool: • Major air and waste facilities: 1 • 21E site (Tier 1D): 1 • Toxics Release Inventory Site ("Tier II"): 1 • MassDEP sites with AULs: 2 • Underground Storage Tanks: 2 • Road Infrastructure: 1 • Railroad: I • Airport: I • Regional Transit Agencies (bus stop): 1 • Energy Generation and Supply (transmission line): 1 The EENF also included an analysis of existing environmental burden using the USEPA EJ Screen. The USEPA EJ Screen tool was run with the "compare to state" option turned on, and the "EJ Index" data layer turned off, for the EJ community within the one-mile DGA. The EJ block group was less than the 50-percentile value for the following indicators: • Particulate Matter 2.5 • Ozone • Air Toxics Cancer Risk • Air Toxics Respiratory HI • Toxic Releases to Air • Traffic Proximity • Lead Paint Compared to state data, the EJ block group was above the 50 percentiles for the following indicators: • 60-70 percentile Diesel Particulate Matter • 60-70 percentile Superfund Proximity • 70-80 percentile RMP Facility Proximity • 60-70 percentile Hazardous Waste Proximity • 60-70 percentile UST • 70-80 percentile Wastewater Discharge The EENF indicates that the identified EJ census block group does not exceed the 80 percentiles for any USEPA indicators. 4 See https:Hmatracking.ehs.state.ma.us/Environmental-Data/ej-vulnerable-health/environmental-justice.html. Four vulnerable health EJ criteria are tracked at the municipal level in the DPH EJ Viewer(heart attack hospitalization, childhood asthma, childhood blood lead,and low birth weight);of these,two(childhood blood lead and low birth weight)are also available at the census tract level. 7 EEA# 16850 EENF Certificate August 16, 2024 According to the EENF, the North Lake Cochichewick Boat Launch Project's primary objectives are to replace the existing failed boat launch, replace the failed concrete and stone retaining wall along Lake Cochichewick, and re-organize the parking, driveway, and boat rack areas. These improvements to public open space, which are publicly available recreational resources, are also beneficial for surrounding Environmental Justice (EJ)populations. The area serves as a key access point for residents engaging in recreational non-motorized boating on Lake Cochichewick during the spring, summer, and fall seasons. The proposed stormwater management system is designed to increase groundwater recharge, reduce scour to Lake Cochichewick, and enhance water quality of the lake, a public drinking water source, relative to existing conditions. Additionally, the enhancements will facilitate emergency access for the North Andover Fire Department's boat, thereby improving public safety and community resilience. The EENF asserts that potential impacts to EJ Populations are expected to be limited to construction period impacts and will be mitigated through construction period BMPs. Traffic during construction and daily operation associated with the Proj ect will primarily be routed along Great Pond Road and not within residential areas located in close proximity. The traffic will generally avoid direct impacts to the EJ block groups within one-mile of the project Site. According to the MA Resilience Design Tool discussed below, the project is rated as having High exposure for Extreme Precipitation(Urban Flooding) and Extreme Heat. As noted in the EENF, to address the climate risks, the project reduces overall impervious area and includes two bioretention area BMPs which are sized for the current 2-, 10-1 25-, and 100-year, 24-hour storms. To minimize the risks associated with Extreme Heat, the project will selectively remove only trees identified as required to construct the proposed block retaining wall. Additionally, the project includes native tree and native shrub plantings. The proposed stormwater improvements will treat and detain stormwater, and permeable pavers will be used to eliminate impervious area and promote groundwater recharge. According to the EENF, these outcomes are expected to provide a benefit for the EJ populations within the one-mile radius, Wetlands and Waterways/Chapter 91 As noted above, the project will result in the alteration of 202 linear feet (If) of Bank, 594 sf of LUWW, and 28,148 square feet (sf) of BLSF. In addition, the project will involve 63 cubic yards (cy) of maintenance dredging. The North Andover Conservation Commission will review the project for its consistency with the Wetlands Protections Act (WPA), the Wetland Regulations (310 CMR 10.00), local bylaws, and associated performance standards. The EENF indicates that a 401 WQC pursuant to 314 CMR 9.04 is required due to planned dredging activities associated with the proposed project. Work within LUWW will include the removal of the failing existing boat launch and construction the new boat launch. Work impacting Bank will include the removal of the existing retaining wall and installation of the new block wall. These alterations will result in a permanent increase in the area of LUWW. The proposed work activities within waters of Lake Cochichewick require a Combined Chapter 91 & 401 Water Quality Certification License. Comments from MassDEP note that the Department did not identify concerns regarding the proposed project and looks forward to submittal of a WWO 1 Water-Dependent License Application after the completion of the MEPA process and includes the minimum necessary 8 EEA# 16850 EENF Certificate August 16, 2024 filing requirements. Additionally, MassDEP notes that portions of the proposed project will occur within the waters of Lake Cochichewick, a geographic area subject to jurisdiction pursuant to 310 CMR 9.04(1)(a). Impervious Area/Stormwater According to the EENF, the proposed stormwater management system consists of two (2) bioretention areas, an overflow structure, conveyance piping, and riprap-lined swale to manage runoff quality and quantity. The project is a redevelopment project and will provide a net reduction in impervious area. The hydrologic analysis of the project was conducted using the 2-, 10-, 25-, and 100-year, 24-hour storms. The project is reducing overall impervious area and implementing bioretention area BMPs which are sized for all design storms. The project is improving upon existing site conditions and therefore making the project site more resilient to climate risks. According to the EENF, the project will result in a net reduction in impervious surfaces of at least 5,000 square feet of impervious area on the property by replacing packed gravel drive and parking areas with permeable pavers. The project incorporates LID elements, such as native plantings in bioretention areas and permeable pavers for the new ramp, driveways, and parking lot. Additionally, a curved block wall is designed to follow the natural contours of the water's edge. The new and improved stormwater management facilities are designed to increase groundwater recharge, reduce scour to Lake Cochichewick, and enhance the water quality of this public drinking water source relative to existing conditions. Rare Species As described previously, the proposed work will occur within an area mapped as Priority Habitat and Estimated Habitat for the "Ligumia nasuta," also known as the "Eastern Pondmussel" as delineated by NHESP in the 15th Edition of the Massachusetts Natural Heritage Atlas. This species and its associated habitat are protected pursuant to the MESA and its implementing regulations (312 CMR 10.00), as well as the rare species provision of the WPA. The Proponet submitted a MESA project review checklist to NHESP on February 8, 2024. NHESP responded with a review letter (File No. 24-17147) on March 15, 2024, which concluded that the project will occur within the actual habitat of the "Ligumia Nasuta," also known as the "Eastern Pondmussel." The conditions set forth in the NHESP review letter required to be followed to prevent a"prohibited take," include the following: • A time of year restriction for the lake drawdown; • A Mussel sweep must be conducted prior to the initiation of work; and • Submittal of a Compliance Report within 30 days of project completion. Consistent with the NHESP issues "List of Conditions for the Project" included in the EENF, a mussel sweep shall be conducted prior to the initiation of work by a Massachusetts Division of Fisheries & Wildlife-approved biologist. Any mussels identified will be relocated to suitable habitats outside the area subject to alteration. Historical and Cultural Resources 9 EEA# 16850 EENF Certificate August 16, 2024 As previously noted, the Massachusetts Historical Commission (MHC) has determined that the project is unlikely to affect significant historic or archaeological resources listed in the State Register of Historic Places or the MHC's Inventory of Historic and Archaeological Assets of the Commonwealth. Climate Change Adaptation and Resiliency Effective October 1, 2021, all MEPA projects are required to submit an output report from the MA Resilience Design Tool to assess the climate risks of the project. Based on the revised output reports, the project has a "High" exposure rating based on the proj ect's location for the following climate parameters: extreme precipitation (urban flooding and riverine flooding) and extreme heat. Based on the 50-year useful life and the self-assessed criticality of the boat launch and parking/driveway, the MA Resilience Design Tool recommends a planning horizon of 2070 and a return period associated with a 10-year (10% chance) storm event when designing for the extreme precipitation parameter. The tool recommends planning for the 50th percentile with respect to extreme heat (which indicates an increase in extremely hot days as compared to a historical baseline). The MA Resilience Design Tool output indicates high exposure to extreme precipitation —urban flooding due to historic flooding at the project site and the maximum annual daily rainfall exceeds 10 inches within the overall proj ect's useful life. In addition, existing trees are being removed as part of the proposed project, and the project site is anticipated to have a 3 0+ days increase in days over 90 degrees Fahrenheit within proj ect's useful life. These factors are indicated in the Tool as contributing to the "High" exposures for the extreme precipitation(urban flooding and riverine flooding) and extreme heat climate parameters. According to the MA Resilience Design Tool output, the projected 24-hour precipitation depth associated with a 2070 10-year storm event is 6.8 inches. Therefore, it appears that the stormwater system, which is designed to convey and provide recharge for the current 100-year storm event (7.93") would be resilient to the future (2070) 10-year storm event as recommended by the Tool. I note that the 10- year storm recommendation is based on assets with a "Low" criticality assessment based on user inputs. The EENF notes that the project includes reducing overall impervious area and implementing bioretention areas sized for to the current 100-year design storm, includes native tree and shrub plantings in two bioretention areas, permeable pavers for the ramp, driveways, and parking lot, and a curved block wall following the water's natural contours. These improvements are designed to reduce stormwater runoff volumes, mitigate pollutants, and restore and support the natural processes that maintain clean water by enhancing groundwater recharge. According to the project plans submitted with the EENF, the project will require the removal of approximately 16 existing trees and shrub including those adjacent to the existing boat ramp and retaining wall whose roots have grown into and around it. Approximately 15 native trees will be planted as part of the project, eight of which are show in the EENF project plans to be planted in the bioretention area. 5 Proponent submitted a revised output report on 7/23/2023 that included an assessment for the proposed boat launch. 10 EEA# 16850 EENF Certificate August 16, 2024 Greenhouse Gas Emissions (GHG) According to the EENF, the project did not perform GHG analysis in accordance with the MEPA GHG Policy because it does not exceed any mandatory EIR thresholds and is not expected to generate 2,000 or more tons per year(tpy) of GHG(CO2) emissions from conditioned spaces that are likely to be used or occupied by EJ Populations. Rather, the EENF states that the project is not expected to generate any increase in greenhouse gas (GHG) emissions compared to existing conditions. Construction Period All construction and demolition (C&D)activities should be managed in accordance with applicable MassDEP regulations regarding Air Pollution Control (310 CMR 7.01, 7.09-7.10), and Solid Waste Facilities (310 CMR 16.00 and 310 CMR 19.00, including the waste ban provision at 310 CMR 19.017). The project should include measures to reduce construction period impacts (e.g., noise, dust, odor, solid waste management, etc.) and emissions of air pollutants from equipment, including anti-idling measures in accordance with the Air Quality regulations (310 CMR 7.11).I encourage the Proponent to require that its contractors use construction equipment with engines manufactured to Tier 4 federal emission standards, or select project contractors that have installed retrofit emissions control devices or vehicles that use alternative fuels to reduce emissions of volatile organic compounds (VOCs), carbon monoxide (CO) and particulate matter(PM) from diesel-powered equipment. Off-road vehicles are required to use ultra-low sulfur diesel fuel (ULSD). If oil and/or hazardous materials are found during construction, the Proponent should notify MassDEP in accordance with the Massachusetts Contingency Plan(MCP; 310 CMR 40.0000). All construction activities should be undertaken in compliance with the conditions of all State and local permits.I encourage the Proponent to reuse or recycle C&D debris to the maximum extent.
