Cutts" <rcuutts l6ndeneng.com> Jennifer &Jean, Just want to let you know that I have reviewed the June 14, 2016 response and revisions to the DPW facility design from Linden Engineering. In general, the design revisions are consistent with the discussions at our meeting last week and do a much better job of meeting the stormwater standards "to the maximum extent practicable". My comments are as follows: 1. The plan shows an approximately 32-ft riprap apron extending into the wetland at the terminus of the existing 36-inch outlet. It is not clear what the basis for the sizing of the apron is since there is only a small amount of flow being added to the existing pipe, and conditions at the outlet are likely to have already stabilized. The Stormwater Handbook calls for sizing calculations based on the anticipated 10- year storm flow from the pipe, but even that may be more than is necessary if there is not significant potential for erosion. 2. A note calling for the existing 36-inch drain to be inspected for structural integrity and cleaned as necessary should be added to the plan. i believe this was discussed at our meeting. 3. It is unclear what the stone drip trench detail on Sheet C-6A pertains to. Sheet C-3A of the plan shows a crushed stone ground cover around the DPW building addition, however it was my understanding that the addition will have a flat roof with the roof drains internally plumbed. While a drip trench may make sense for the new salt storage building there is nothing on the plan that calls for one. 4. The note regarding snow storage on the site should be included in the O&M Plan and/or operational SWPPP and should indicate that all drainage structures are to be kept clear of snow and that excess snow should be removed from the site. The ConCom may also want to require signage along the wetland boundary. 5. The third (existing) CB along Wayne Street should be included in the O&M figure, cleaned, and maintained on an ongoing basis. 6. As discussed, the Boards may want to make the updating and implementation of the operational SWPPP for the facility within a reasonable time frame a condition of approval. 7. 1 was unable to find the note pertaining to the NPDES Construction General Permit (my previous comment#11) on the revised plans. Let me know if you have any questions. Lisa D. Eggleston, P.E.

This letter was briefly discussed at the public hearing before the Conservation Commission on June 8, 2016. In addition, a meeting was held at the North Andover DPW building on June 13, 2016 with the Conservation Administrator, the Peer Review Consultant, the Assistant Town Manager, the DPW I Director, the Architect and our firm to discuss the comments and revisions to the project. l The following are the comments contained in the peer review letter report and our responses to the comments. We have also revised the design plans prepared by our firm for the project and the revised u design plans dated June 14, 2016 are attached to this letter. 1. "The proposed project qualifies as a redevelopment project under MA Stormwater Standard 7, hence it is required to comply with Standards 2 and 3 and the pretreatment and structural best i management practice requirements of Standards 4, 5 and 6 only to the maximum extent i, practicable. However, as set forth in the DEP Stormwater Handbook, to the maximum extent practicable"means that the proponent has made all reasonable efforts to fully meet all of the Standards, and that the highest practicable level of sformwater management for the project is being implemented. In addition, all redevelopment projects are required to improve existing the proposed project would likelynot increase the rate of Based on the plan submitted, conditions. p p P p J runoff from the site and would provide some improvement in the water quality of the runoff discharged through the two new outfalls. I also concur that the recharge of sformwater is neither feasible nor appropriate for this site. As is described further in my comments below however, the proposed plan would not provide full compliance with the Stormwater Standards and 1 do not believe that the Applicant has satisfactorily demonstrated that full or at least better compliance is not practicable." As discussed at the meeting on June 13th, the options available for the site to reach full compliance with Stormwater Standards 4, 5 &6 are limited by the soils, groundwater conditions and topography at the site. The incorporation of LID measures such as a Rain Garden are not possible as at the front of the site the proposed building has roof drains that are collected and internally piped. The discharge pipes from the building discharge with a minimum of 3 feet of cover placing Civil—Environmental Engineering including Storm water,Wastewater,Water Supply,Highway&Infrastructure Design Land Planning,Land Subdivision,Site Design,Environmental Permitting,Wetlands Permitting&Land Development Permitting Town of North Andover Conservation Commission Re: Response to Peer Review Letter Report, MADEP File No. 242-1681 North Andover Department of Public Works, 384 Osgood Street, North Andover, MA June 14, 2016, Page 2 of 5 the pipe invert nearly 4 feet below existing grade, The use of a rain garden would require excavation five feet below grade in poor soils. Any water in the rain garden would not percolate through the soils in 72 hours as required and disturbance of Bordering Vegetated Wetlands and Bank would be necessary for the outlet from the rain garden. At the rear of the site the same limitations in terms of soils, groundwater and topography exist making the use of LID measures unfeasible. 2. "The proposed drainage design includes inline Stormceptor proprietary separators as the sole BMP to treat the runoff discharged through the two new outfalls, and the TSS calculations assume a removal rate in the of 80% TSS in the units. Based on data presented by Tom Maguire of MassDEP and Jerry Schoen of MaSTEP in their 2013 workshop on evaluating proprietary separators (http://www.mastep.net/documents/MassDEP Evaluating Nonrated Stormwater Treafinent.pdo, a more realistic TSS removal rate for proprietary separators in general is somewhere in the vicinity of 25-50 percent, but even this does not take into account the presence of upgradient catchbasins, which would already have removed some of the same coarse sediments that are most effectively treated in the Stormceptor units. The Stormwater Handbook(Volume 2, Chapter 2, pg 10) states that proprietary separators must be used for pretreatment and be placed first in the treatment train to receive TSS removal credit. Proprietary separators may be used as treatment BMPs in redevelopment projects where it has been demonstrated that suitable alternatives do not exist, however no documentation of alternatives considered was included in the materials I reviewed. With the proposed addition of the two new outfalls 1 also don't believe that the proposed sformwater management for the site would comply with Stormwater Standard 1, since it specifically states that"no new sformwater conveyances (e.g. outfalls) may discharge untreated sformwater directly to or cause erosion in wetlands or waters of the Commonwealth."" As was discussed at the meeting, the data and information on proprietary separators varies depending on the source used. We provided data with the Notice of Intent indicating that the Stormceptor is acceptable for a 75% TSS removal rate by NJ CAT. However, the proposed project is only required to meet the 80% TSS removal requirement to the extent practicable. Given the soils, groundwater and topographic limitations the only available treatment options are proprietary separators which is what we are proposing for the project. 3. "Per DEP criteria, the separators would need to be placed in an offline configuration to maximize treatment effectiveness and prevent carryover of accumulated sediments." The Stormceptor units proposed have an internal bypass weir to bypass flows in excess of the treatment flow without re-entraining the solids previously settled out of the runoff stream. In addition, the unit proposed for the front area has a treatment flow (3.4 cfs) which is greater than the full 100 year flow from the roof and parking area (2.14 cfs). As discussed at the June 131h meeting, the separator at the rear of the site has been upsized and moved to be on the 36' drain so that with i i Town of North Andover Conservation Commission Re: Response to Peer Review Letter Report, MADEP File No. 242-1681 North Andover Department of Public Works, 384 Osgood Street, North Andover, MA June 14, 2016, Page 3 of 5 the reconfigured drainage it will treat the on-site runoff from the new catch basins and a large portion of the runoff from the�abutting neighborhoods ' 4. "Per DEP criteria, the separators would need to be placed in an offline configuration to maximize treatment effectiveness and prevent carryover of accumulated sediments." Per a discussion with Mr. Thomas Maguire of the Mass DEP, the roof runoff is exempt from the pre-treatment requirements but it is not exempt from the 80% TSS treatment requirements. In addition, the unit proposed for the front area has a treatment flow (3.4 cfs) which is greater than the full 100 year flow from the roof and parking area (2.14 cfs). 5. "The Alternate Bid portion of the project site constitutes a Land Use with Higher Potential Pollutant Loading(LUHPPL) therefore the 5formceptor treating runoff from that area needs to be sized for a one-inch water quality volume on an equivalent flow basis." The comment is correct and the revised sizing calculation is as follows: Impervious Area =17499 s.f., time of concentration = 0.10 hours WQF = (qu)(A)(WQV) WQF = (774 csmlin)((17499/43560) acres)(0.0015625 mi2/acre)(1.0 in) WQF=0.48 CFS Note: The Unit chosen is a Stormceptor STC-2400 which can treat 5.4 cfs. Therefore, the unit will be fully capable of treating the water quality volume from the captured impervious areas at the rear of the site and has a large excess capacity to treat the runoff from the neighborhood in the 36" pipe. 6. "It is not clear from the plan where the roof runoff from the new salt shed would be discharged." The salt shed has no roof drains and runoff from the structure spills onto the adjacent pavement. 7. "As proposed, only a portion of the runoff from the Alternate Bid portion of the site would undergo any stormwater treatment; the majority of the runoff would continue to drain untreated to adjacent wetland areas. Again, no documentation of alternatives considered or demonstration that the proposed plan constitutes compliance to the "maximum extent practicable"has been provided in the materials I reviewed. As these areas contain some of the dirtiest operations of the site in terms of stormwater quality i believe that significantly more can be done to improve existing conditions both through the addition of stormwater BMPs and operational improvements aimed at minimizing pollutant sources. As discussed at the meeting on June 13th, the options available for the rear of the site to reach full compliance with Stormwater Standards 4, 5 &6 are limited by the soils, groundwater conditions and topography at the site. The incorporation of LID measures such as a Rain Garden are not possible due to the soils, high groundwater and extremely flat topography. The use of a rain garden would require excavation into the groundwater. On the revised plan, additional stormwater i i Town of North Andover Conservation Commission Re: Response to Peer Review Letter Report, MADEP File No. 242-1681 North Andover Department of Public Works, 384 Osgood Street, North Andover, MA June 14, 2016, Page 4 of 5 treatment has been provided by the addition of a new double rim catc_h.basin opposite the fuel. ,island, adding Eliminator catch basin hoods to the two other catch basins along Wayne Street and placing a Stormceptor STC 2400 on the 36" discharge pipe to provide some treatment of the runoff fro m this portion of the"sit'e and the neighborhood prior to discharge to the brook. 8. "in addition to structural BMPs, Stormwater Standard 4 requires a Long Term Pollution Prevention Plan identifying suitable practices for source control and pollution prevention, and Stormwater Standard 5 requires the implementation of source controls and pollution prevention measures on the LUHPPL to eliminate or minimize pollutant exposure to stormwater. Redevelopment projects are not exempted from complying with these requirements fully. If the Town already has a Pollution Prevention Plan for Municipal Operations as is required by EPA's NPDES Phase 2 Permit for Small MS4s that should fulfill the requirements of Standards 4 and 5, however there was no reference to such a plan in the materials i reviewed and it does not appear that one is currently being implemented on the site. The "Good Housekeeping BMPs"included with the O&M Plan are generic and not specific to the operations on the site." The Town of North Andover Department of Public Works has a Pollution Prevention Plan which contains all of the required information, The plan is entitled, "Stormwater Pollution Prevention Plan For the Department of Public Works Facility, 384 Osgood Street, 225073.08, North Andover, MA" prepared by Woodard and Curran dated June 29, 2012. Reference is made to this plan for Standards 4 & 5. 9. "It is unclear why the plan calls for a portion of the pavement to the north of the new salt shed to be removed and replaced with a gravel surface. If these areas of the site are to continue to be used for materials and equipment storage an impervious surface is more easily swept to remove excess sediments etc. and provides more opportunity for spill control and containment." Based on the discussions at the June 13th meeting the plans have been revised to retain the paved areas around the salt shed as pavement and not as gravel. 10. "The catchbasin outlet hood should be specified on the plan; 1 recommend the LeBaron Snout or Eliminator brands." The detail on the plans has been revised to specify the use of the Eliminator brand hoods. i 11. "If the Alternate Bid is included, the proposed project would entail the disturbance of more than one acre of land and be subject to EPA's NPDES Construction General Permit(CGP). Prior to the initiation of work the selected contractor will need to file a Notice of Intent for coverage under the CGP, and prepare a Stormwater Pollution Prevention Plan (SWPPP) to be implemented during construction. This requirement should be clearly noted on the plans. The Conservation Commission may also want to require proof of filing of the NOl and the opportunity to review the SWPPP prior to the start of work." A note regarding this has been added to the plans. i I I I i Town of North Andover Conservation Commission Re: Response to Peer Review Letter Report, MADEP File No. 242-1681 North Andover Department of Public Works, 384 Osgood Street, North Andover, MA June 14, 2016, Page 5 of 5 12. "1 have the following comments on the Operation and Maintenance (O&M) Plan included in the Stormwater Report: • Short-term, construction related measures should be removed from the O&M Plan and included in a separate construction SWPPP. The long-term plan should be structured as a standalone document to be maintained on site. • Catchbasins on the site should be inspected at least 4 times per year and cleaned a minimum of once per year, not just when sediment thresholds are reached. • Stormceptor units should also be cleaned a minimum of once per year, with a vacuum truck. • The plan should include a maintenance checklist and a simple figure showing the locations of all stormwater BMPs to be maintained. • Designated snow storage locations should also be shown on the plan/figure. To the extent possible, snow storage should be located upgradient of the stormwater BMPs. The Operation and Maintenance (O&M) Plan has been revised and is attached to this letter. 13. "Stormwater Standard 10 prohibits all illicit discharges to the stormwater management system and requires proponents to submit an Illicit Discharge Statement demonstrating that no illicit connections exist on the project site. Redevelopment projects must fully comply with this requirement, and must also document all actions taken to identify and remove illicit discharges, including, without limitation, visual screening, dye or smoke testing, and the removal of any sources of illicit discharges to the stormwater management system. This requirement has not yet been met for this project. Since the proposed plan calls for portions of the existing drainage infrastructure and some of the buildings to remain on the site they will need to be thoroughly investigated before such a statement can be made." This investigation has previously been made by the Department of Public Works and a signed Illicit j Discharge Statement is attached to this response. i We look forward to discussing the project, the report, our responses and any questions that the Conservation Commission may have at the continued public hearing for the project.

No spilled hazardous materials or hazardous wastes will be allowed to come in contact with storm water discharges. If such contact occurs, the storm water discharge will be contained on site until appropriate measures in compliance with state and federal regulations are taken to dispose of such contaminated storm water. It shall be the responsibility of the site superintendent to properly train all personnel in spill prevention and clean up procedures. In order to minimize the potential for a spill of hazardous materials to come into contact with storm water, the following steps will be implemented: 1. All materials with hazardous properties (such as pesticides, petroleum products, fertilizers, detergents, construction chemicals, acids, paints, paint solvents, cleaning solvents, additives for soil stabilization, concrete curing compounds and additives, etc.)will be stored in a secure location, with their lids on, preferably under cover, when not in use. 2. During construction, liquid petroleum products and other hazardous materials with the potential to contaminate groundwater may not be stored or handled in areas of the site draining to an infiltration area, An "infiltration area" is any area of the site that by design or as a result of soils, topography and other relevant factors accumulates runoff that infiltrates into the soil. Dikes, berms, sumps, and other forms of secondary containment that prevent discharge to groundwater may be used to isolate portions of the site j for the purposes of storage and handling of these materials I 3. The minimum practical quantity of all such materials will be kept on the site at all times. 3 j 4. A spill control and containment kit (containing, for example, absorbent materials, acid neutralizing powder, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal trash containers, etc.) will be provided at the storage site. Catch basin inlet cover blankets and inflatable pipe plugs will be used to seal the openings in the outlet pipes and isolate product in the drainage system should a spill occur. 5. Manufacturer's recommended methods for spill cleanup will be clearly posted and site personnel will be trained regarding these procedures and the location of the information and cleanup supplies. € In the event of a spill, the following procedures should be followed: 1 All spills will be cleaned up immediately after discovery. v 2. The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to 'i prevent injury from contact with the hazardous substances. 3. The project manager and the Engineer of Record will be notified immediately. Operation And Maintenance Plan, Town Of North Andover Department Of Public Works Improvements To The Public Works Building, 384 Osgood Street, North Andover, Ma May 27, 2016, Revised June 14, 2016, Page 4 of 6 4. Spills of toxic or hazardous materials will be reported to the appropriate federal, state, and/or local government agency, regardless of the size of the spill. 5. If the spill exceeds a Reportable Quantity, MADEP must be notified and provided with a description of the release, the circumstances leading to the release, and the date of the release and all abatement and followup measures implemented. The site superintendent will be the spill prevention and response coordinator. He will designate the individuals who will receive spill prevention and response training. These individuals will each become responsible for a particular phase of prevention and response. The names of these personnel will be posted in the material storage area and in the office trailer onsite. Allowable Non-Stormwater Discharge Management Certain types of will be allowed under the conditions that no pollutants will be allowed to come into contact with the water prior to or after its discharge. The control measures that have been outlined previously in this O & M Plan will be strictly followed to ensure that no contamination of these non-stormwater discharges takes place. The following non-stormwater discharges that may occur from the site include: • Discharges from fire-fighting activities • Fire Hydrant flushings • Waters used to wash vehicles where detergents are not used • Water used to control dust in accordance with off-site vehicle tracking • Potable water including uncontaminated water line flushings • Routine external building wash down that does not use detergents • Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents are not used • Uncontaminated air conditioner compressor condensate • Uncontaminated ground water or spring water • Foundation or footing drains where flows are not contaminated with process materials such as solvents • Uncontaminated excavation dewatering • Landscape irrigation 3 Post-Construction BMP's I Several types of structural and non-structural water quality controls in various combinations are proposed to treat stormwater generated on the site. These measures include deep sump catch basins with hoods and stormwater treatment units. These Water quality treatment measures will result in the removal of a n minimum of 80 percent of the total suspended solids (TSS) load in runoff prior to discharge from the site, consistent with DEP's TSS removal standard.

BMPs Used Drainage Inlet with Deep Sump i i Stormceptor Proprietary Treatment Unit Post-Development Activities 1. Paved Areas: Paved Areas shall be mechanically swept during the dry weather to remove excess sediments, thereby reducing the amount of sediments that the drainage system will have to remove from the runoff. Paved areas shall be mechanically swept a minimum of once each year(in the spring). 2. The use of salt or chemicals for de-icing on the paved areas during the winter months shall be limited to the amount necessary to maintain pedestrian and vehicle safety. 3. Catch Basins with Deep Sump and Hood: The catch basins shall be inspected at least four timeslyear and at the end of the snowfall and foliage seasons to verify that the inlet openings are not clogged by debris. Debris shall be removed from the inlet grates and disposed of properly. The catch basin sumps shall also be inspected a minimum of four times per year and shall be cleaned whenever the j depth of the sediment is 25% or more of the sump depth or at least a minimum of twice per year. Material 3 shall be removed from the catch basin sumps shall be disposed of in accordance with all applicable 3 regulations. 4. The Stormceptor Stormwater Treatment Unit shall be inspected and cleaned with a vacuum truck a minimum of four times per year for the first year and cleaned with a vacuum truck a minimum of two times per year every year after the first year of operation. Cleaning shall be in strict conformance with the manufacturer's recommendations which are attached to this report. 1 a All maintenance responsibilities as identified within this document will be owned and maintained by the owner of the property and shall run with the title of the property. Annual Operating Budget The estimated annual operating budget for the O & M Plan for the base bid project is $ 750. The estimated annual operating budget for the O & M Plan for the bid alternate project is $ 1,250.

I also conducted a brief site visit on June 2, 2016 to observe existing drainage patterns. My primary focus in this technical review is on the overall stormwater management approach and design concepts used in the project, as well as its compliance with the Town of North Andover's Site Plan Review regulations, the Massachusetts Department of Environmental Protection (DEP) Stormwater Management Standards and Regulations, and the North Andover Wetlands Bylaw. It is my understanding that a Notice of Intent (NOI) application for the project has been filed concurrently with the Conservation Commission. My review is aimed at assisting both boards in their respective reviews of the project. 32 Old Framingham Rd Unit 29 Sudbury MA 01776 tel 508.259.1137 DPW Building Improvements 2 June 8, 2016 The project site is an approximately 3.58-acre parcel at the intersection of Osgood Street and Wayne Street. It is currently occupied by the North Andover Department of Public Works and includes a large storage/office building with associated parking, salt storage building, vehicle fueling depot and exterior materials and equipment storage. There are presently only a few drainage structures along the western (Wayne Street) edge of the site, which discharge via a 36-inch drain across the site toward Cochichewick Brook to the north. The site is relatively flat and much of the drainage is overland directly to the adjacent wetlands to the north and west. The proposed Base Bid plan calls for a two-story addition to the existing building and reconfiguration of the existing parking area. As proposed, runoff from the new parking area would be collected in a closed drainage system with deep sump catchbasins and drain through a Storrnceptor treatment unit prior to discharge via a new outall to the wetlands associated with Cochichewick Brook. Roof runoff from the building addition would also be drained through the Stormceptor unit and discharged through the new outfall. - The work proposed under the Alternate Bid includes removal of the existing storage building and construction of a new salt shed as well as regrading and repaving of the areas surrounding the new shed. As proposed, the runoff from a portion of the pavement area would be collected in a closed drainage system with deep surnp catchbasins and drain through a Stormceptor treatment unit prior to discharge via a new outall to the wetlands associated with Cochichewick Brook. My comments on the propsed design are outlined below. Please note that these comments should be considered preliminary at this time, as I have not yet had the opportunity to review the full Conservation Commission submittal packet: l. The proposed project qualifies as a redevelopment project under MA Storniwater Standard 7, hence it is required to comply with Standards 2 and 3 and the pretreatment and structural best management practice requirements of Standards 4, 5 and 6 only to the maximum extent practicable. However, as set forth in the DEP Stormwater Handbook, "to the maximum extent practicable" means that the proponent has made all reasonable efforts to fully meet all of the Standards, and that the highest practicable level of stormwater management for the project is being implemented. In addition, all redevelopment projects are required to improve existing conditions. Based on the plan submitted, the proposed project would likely not increase the rate of runoff from the site and would provide some improvement in the water quality of the runoff discharged through the two new I outfalls. I also concur that the recharge of stormwater is neither feasible nor appropriate for this site. As is described further in my comments below however, the proposed plan would not provide full compliance with the Stormwater Standards and I do not believe that the Applicant has satisfactorily demonstrated that full or at least better compliance is not practicable. Y G 0 P k ¢G DPW Building Improvements 3 June 8, 2016 2. The proposed drainage design includes inline Stormceptor proprietary separators as the sole BMP to treat the runoff discharged through the two new outfalls, and the TSS calculations assume a removal rate in the of 80% TSS in the units. Based on data presented by Tom Maguire of MassDEP and Jerry Schoen of MaSTEP in their 2013 workshop on evaluating proprietary separators (bP..://w.w.w—,.I...II...gust l t�1 q ments/MassDEP Evaluat tngl catlrated...to.r..m......w....a..te.r..Treatment.p_df.), a more realistic TSS removal rate for proprietary separators in general is somewhere in the vicinity of 25-50 percent, but even this does not take into account the presence of upgradient catchbasins, which would already have removed some of the same coarse sediments that are most effectively treated in the Stormceptor units. The Stormwater Handbook (Volume 2, Chapter 2, pg 10) states that proprietary separators must be used for pretreatment and be placed fast in the treatment train to receive TSS removal credit. Proprietary separators may be used as treatment BMPs in redevelopment projects where it has been demonstrated that suitable alternatives do not exist, however no documentation of alternatives considered was included in the materials I reviewed. With the proposed addition of the two new outfalls I also don't believe that the proposed stormwater management for the site would comply with Stormwater Standard 1, since it specifically states that "no new stormwater conveyances (e.g. outfalls) may discharge untreated stormwater directly to or cause erosion in wetlands or waters of the Commonwealth." 3. Per DEP criteria, the separators would need to be placed in an offline configuration to maximize treatment effectiveness and prevent carryover of accumulated sediments. 4. As proposed, roof drainage frorn the building addition would be discharged through the Stormceptor unit located in the front parking area. Since roof drainage is considered clean it does not need to be treated, hence the addition of this flow would merely reduce the Stormceptor's effectiveness in treating the pavement runoff. 5. The Alternate Bid portion of the project site constitutes a Land Use with Higher Potential Pollutant Loading (LUI-IPPI.,) therefore the Stormceptor treating runoff from that area needs to be sized for a one-inch water quality volume on an equivalent flow basis. 6. It is not clear from the plan where the roof runoff from the new salt shed would be discharged. 7. As proposed, only a portion of the runoff from the Alternate Bid portion of the site would undergo any stormwater treatment; the majority of the runoff would continue to drain untreated to adjacent wetland areas. Again, no documentation of alternatives considered or demonstration that the proposed plan constitutes compliance to the "maximum extent practicable" has been provided in the materials I reviewed. As these areas contain some of the dirtiest operations of the DPW Building Improvements 4 June 8, 2016 site in terms of storrnwater quality I believe that significantly more can be done to improve existing conditions both through the addition of stormwater BMPs and operational improvements aimed at minimizing pollutant sources. 8. In addition to structural BMPs, Stormwater Standard 4 requires a Long Term Pollution Prevention Plan identifying suitable practices for source control and pollution prevention, and Stormwater Standard 5 requires the implementation of source controls and pollution prevention measures on the LUHPPL to eliminate or minimize pollutant exposure to stonnwater. Redevelopment projects are not exempted from complying with these requirements fully. If the Town already has a Pollution Prevention Plan for Municipal Operations as is required by EPA's NPDES Phase 2 Permit for Small MS4s that should fulfill the requirements of Standards 4 and 5, however there was no reference to such a plan in the materials I reviewed and it does not appear that one is currently being implemented on the site. The "Good Housekeeping BMPs" included with the O&M Plan are generic and not specific to the operations on the site. 9. It is unclear why the plan calls for a portion of the pavement to the north of the new salt shed to be removed and replaced with a gravel surface. If these areas of the site are to continue to be used for materials and equipment storage an impervious surface is more easily swept to remove excess sediments etc. and provides more opportunity for spill control and containment. 10. The catchbasin outlet hood should be specified on the plan; I recommend the LeBaron Snout or Eliminator brands. 11. If the Alternate Bid is included, the proposed project would entail the disturbance of more than one acre of land and be subject to EPA's NPDES Construction General Permit (CGP). Prior to the initiation of work the selected contractor will need to file a Notice of Intent for coverage under the CGP, and prepare a Stormwater Pollution Prevention Plan (SWPPP) to be implemented during construction. This requirement should be clearly noted on the plans. The Conservation Commission may also want to require proof of filing of the NOI and the opportunity to review the SWPPP prior to the start of work. 12. 1 have the following comments on the Operation and Maintenance (O&M) Plan included in the Stormwater Report: Short-term, construction related measures should be removed from the O&M Plan and included in a separate construction SWPPP. The long-term plan should be structured as a standalone document to be maintained on site. ■ Catchbasins on the site should be inspected at least 4 tunes per year and cleaned a minimum of once per year, not just when sediment thresholds are reached. Stormceptor units should also be cleaned a rninimurn of once per year, with a vacuum truck. a t DPW Building Improvements 5 June 8, 2016 ■ The plan should include a maintenance checklist and a simple figure showing the locations of all stormwater BMPs to be maintained. Designated snow storage locations should also be shown on the plan/figure. To the extent possible, snow storage should be located upgradient of the stormwater BMPs. 13. Stormwater Standard 10 prohibits all illicit discharges to the stormwater management system and requires proponents to submit an Illicit Discharge Statement demonstrating that no illicit connections exist on the project site. Redevelopment projects must fully comply with this requirement, and must also document all actions taken to identify and remove illicit discharges, including, without limitation, visual screening, dye or smoke testing, and the removal of any sources of illicit discharges to the stormwater management system. This requirement has not yet been met for this project. Since the proposed plan calls for portions of the existing drainage infrastructure and some of the buildings to remain on the site they will need to be thoroughly investigated before such a statement can be made. I appreciate the opportunity to assist the North Andover Planning Board and Conservation Commission with the review of this project, and hope that this information is suitable for your needs.
