CERTIFIED MAIL February 13, 2008 Elizabeth Rennard, Esq. Salem—Solid Waste/COR City Solicitor Salem Landfill City Hall 12 Swampscott Road 93 Washington Street Facility No. 39974 Salem, MA 01970 Re: Noncompliance Landfill Closure NOTICE OF ENFORCEMENT CONFERENCE THIS IS AN IMPORTANT NOTICE. FAILURE TO RESPOND TO THIS NOTICE COULD RESULT IN SERIOUS LEGAL CONSEQUENCES. Dear Ms. Rennard: On May 11, 2006, at the request of the City of Salem representatives of the Department of Environmental Protection,Northeast Regional Office, Bureau of Waste(the "MassDEP") met with Mayor Driscoll, you and other representatives of the City of Salem (the "City") to discuss the closure of the Salem Landfill (the "Landfill"). The closure of the landfill is required pursuant to an Administrative Consent Order with Penalty, File No. ACOP-NE-01-4005, that was executed on April 4, 2002 (the "Order") between the MassDEP, the City, and Northside Carting. At the meeting the City represented that it did not have the funds to move forward with the closure of the Landfill. The City proposed instead to issue a Request for Proposal (the "RFP") for the sale or long-term lease of the property. The RFP would require the new owner to complete the closure of the Landfill in accordance with the Order and 310 CMR 19.000, the Massachusetts Solid Waste Regulations. On June 12, 2006, the City's consultant, Alliance Environmental Group, Inc. ("Alliance") submitted a schedule to the MassDEP for completing the RFP process and closing the landfill. The schedule provided for the issuance of the RFP by September 2006, selection of proposal by December 2006, and completion of the closure by June This information is available in alternate format.Call Donald M.Comes,ADA Coordinator at 617556-1057.TDD#864539-7622 or 617-574-6868. http://w v.mass.gov/dep•Fax(978)694-3499 C� Printed on Recycled Paper Salem Page 2 of 4 Salem Landfill NOEC This is an electronic facsimile of a document on file with the Massachusetts Department of Environmental Protection. 2008. On March 28, 2007, the MassDEP received a letter from you indicating that the City was evaluating two proposals in response to the RFP. As described, below the City is currently not in compliance with one or more laws, regulations, orders, licenses, permits or approvals enforced by the MassDEP. The noncompliance consisted of violations involving 310 CMR 19.000, the Massachusetts Solid Waste Management regulations, in particular, the failure to complete the closure of the Landfill in accordance with the terms of the Order, specifically: 1. Paragraph 15.C.7. of the Order requires in part that: "Within sixty(60) days of the Department's [MassDEP's] approval of the CAAA [Corrective Action Alternative Analysis], [the Parties] submit, for the Department's approval, a Corrective Action Design(CAD), if necessary in accordance with the regulations......" The MassDEP approved the CAAA on April 20, 2005. 2. Paragraph 15.C.8. of the Order requires that: "November 1, 2004, [the City and Northside Carting (the "Parties")] complete all necessary corrective actions, including the installation of an approved final cover system and obtaining approval of any existing unapproved post-closure uses, in accordance with the regulations, Guidance Manual [Landfill Technical Guidance Manual] and the approved CAD [Corrective Action Design]." 3. The Order provides that the City shall pay administrative penalties to the Commonwealth of Massachusetts for violations of the Order, specifically: a. Paragraph 20.B. of the Order provides that: "In the event the City violates any provision of this Consent Order, or further violates any of the requirements cited in Part II above, the City shall pay to the Commonwealth the sum of Thirteen Thousand Seven Hundred Fifty($13,750) Dollars within thirty(30) days of receipt of the Department's written notice thereof." b. Paragraph 21 of the Order provides that the City shall pay stipulated penalties of up to Two Thousand ($2,000) Dollars per day for violations of the Order. The Order further provides that stipulated penalties shall begin to accrue on the day of the violation(s) and shall to accrue until the day the violation is corrected. As of the date of this Notice the City has failed to comply with the requirements of paragraphs 15.C.7. and 8. of the Order. SalemLdf_City_NOEC08_02_l3.doc 2/13/08 Salem Page 3 of 4 Salem Landfill NOEC This is an electronic facsimile of a document on file with the Massachusetts Department of Environmental Protection. Due to these noncompliance issues,the MassDEP intends to take enforcement action against the City. Possible actions include issuance by the MassDEP of an ENFORCEMENT ORDER, a CIVIL ADMINISTRATIVE PENALTY and/or referral of the matter for ATTORNEY GENERAL'S OFFICE, CIVIL or CRIMINAL PROSECUTION. An enforcement conference has been scheduled at this office on the following date and time: LOCATION: MassDEP Northeast Regional Office 205B Lowell Street Wilmington,Massachusetts 01887 DATE: March 13, 2008 TIME: 2:00 PM The purpose of the enforcement conference is to provide you with the opportunity to reach a negotiated agreement with the MassDEP to return to compliance and pay a civil administrative penalty as appropriate. The MassDEP believes that prompt resolution of this enforcement case in a manner which ensures your expeditious return to compliance and resolves all penalty issues is beneficial and consistent with the MassDEP's environmental protection goals. The enforcement conference will provide you with the opportunity to discuss the alleged violations and return to compliance and/or penalty conditions of a final enforcement document. Prompt settlement may also decrease the resources you and the MassDEP might expend on protracted litigation of the issues. If you do not attend the enforcement conference and reach a negotiated settlement, the MassDEP will initiate appropriate enforcement action and you will have limited, if any, further opportunity to reach a negotiated settlement of this case. These enforcement actions by MassDEP may include but not be limited the issuance of a demand for the payment of the suspended penalty of Thirteen Thousand Seven Hundred Fifty ($13,750) Dollars pursuant to paragraph 20.B. of the Order, the assessment of stipulated penalties pursuant to paragraph 21 of the Order, and/or issuance of an Unilateral Administrative Order by MassDEP establishing a schedule for completion of the closure of the Landfill. By March 8, 2008, please contact me at 978-694-3299 to confirm your attendance at the Enforcement Conference and whether or not the City will have an attorney present.

It was reported that downgradient properties have experienced flooding . problems. These preliminary calculations are provided to indicate the intent to maximize the natural storage area for large storm events between the culvert and Highland Avenue while maintaining flow during normal conditions. Existing Condition: Topographic information is approximate and was based obtained from MassGIS 3-meter contours. Soils information is based on NRCS soil maps. The subcatchment area contributing to the culvert is approximately 93 acres. Upgradient flow from approximately 75 acres must pass through a 15 inch culvert under Highland Avenue. During larger stone events this pipe restricts flow and ponding occurs north of Highland Avenue. Outlet of this pipe plus additional runoff area from Highland Avenue and adjacent properties convey stormwater runoff to the existing 200 foot 48 inch culvert through the project site. Over the years debris and sediment have accumulated to significantly limit the inlet capacity of this pipe. Proposed Condition: The proposed design calls for daylighting approximately 60 feet of the 48 inch culvert. In order to simulate the blocked condition of the existing pipe a control structure is proposed to maximize the upgradient storage that most likely occurs today. As an added benefit to the daylighting additional storage capacity will be provided (see attached HydroCAD calculation). Conclusion: The proposed project and associated mitigation measures are provided to improve the existing conditon and will not adversely impact downgradient properties.

On behalf of Northside Carting, Inc. and the City of Salem, we have provided the following responses in bold text. Copies of the referenced documents are included as Attachments. ➢ Use of filter bags in lieu of haY bales and silt fence for erosion control at limits of work. tWe agreed to the use of Straw Wattles7m and/or FiltrexxTM filter socks in lieu of hay bales and silt fence, to avoid introduction of invasive species of plants. See tattached product sheet in Attachment A. ➢ What will be done with respect to general site cleanup includingstockpiled tockpiled pipes ' curbs and miscellaneous building materials? All existing surface debris around the property, including the shoreline along the ' western boundary of the property, will be cleaned up and disposed off-site, or incorporated under the DEP-approved landfill cap at this site. To the extent that the miscellaneous pipes, curbs and other stockpiled materials are desired by ' the City, they will be relocated by City forces to an alternative storage location. Otherwise, they will become the property of Northside Carting, Inc. upon transfer of the property and the materials will either be relocated for re-use, or ' demolished for placement under the landfill cap or under paved areas in accordance with DEP's conditional approval of the CAAA Report and the DEP's Asphalt, Brick and Concrete (ABC) Re-use Policy. 1 1 ' Lincoln,RI Norwood,MA Rocky Hill,CT Ms. Carey Duques, Agent ' March 7, 2008 Page 2 of 3 ' ➢ What will happen with the construction debris generated from demolition of the existing incinerator building and stack? ' In accordance with DEP's conditional approval of the CAAA Report, re-use of the demolition debris (after abatement of regulated building materials) will be ' permitted under the paved areas of the site to help achieve final grades. Care will be taken during placement of the C&D debris, including embedded gravel layers and compaction, to avoid future settlement. ' ➢ Have the building materials, ash and other"suspect" materials inside the incinerator building and stack been sampled for hazardous residuals? ' The answer is that most of the materials were sampled during a pre-demolition survey conducted in July 2005. The primary contaminants of concern include: ' ■ Asbestos containing building materials (roofing materials, wall panels, gaskets, duct insulation, mastics and floor tiles); ' • Lead based painted surfaces; and ■ Pigeon guano. The ash within the chimney has not yet been tested, but we plan to test the ash ' for heavy metals prior to demolition. In most cases, the ash will be similar to all of the other ash on the site and will be suitable for placement under the ' engineered cap. In the event the total metals exceed certain threshold values, we will perform toxicity characteristic leaching procedure tests to assess management requirements. ' ➢ Where will the drainage pipes be installed with respect to the engineered cap for the site? All drainage pipes will be installed above the engineered impervious liner; however, the drainage structures will be provided with a "geotextile skirt" sealed ' with bentonite to prevent infiltration of rainwater around the periphery of the drainage structures. The skirt will be similar to that illustrated on the guardrail detail included in Attachment C. Reference is also made to the Detail Sheet included in Attachment B. ' ➢ Will the guard rail supports be installed above or below the geotextile barrier? Reference is made to the detail included in Attachment C which illustrates the ' guard rail installation detail. The support will penetrate the geotextile fabric to an approximated depth of 4 to 6 feet below grade.

' BETA has performed a preliminary hydrologic analysis and determined that the existing 48-inch diameter culvert is oversized for the drainage basin. ' Furthermore, restoring its full flow capacity could result in worsening downstream flooding problems. Based upon the initial modeling results, we will likely recommend installation of a concrete headwall/structure with an inlet ' control device. In the event the existing culvert is not suitable for re-use, replacement with an 18-inch or 24-inch diameter reinforced concrete pipe will be recommended. Final modeling results will be available for the next public hearing on Thursday night (3/13). ➢ Details of the"r posed Stormceptor and manholes should be provided ' Details of the drainage manholes and inlet structures were included on the detail sheet submitted with the Supplemental NOI package submitted at the public hearing on February 28, 2008.

Compost and composted mulch are mostly organic matter and approximately 60 to 80% of the stable organic matter content in compost is in the form of humus. Humus, organic matter, and compost have each been ' well documented in the scientific research literature as effective pollutant filtration devices evaluated by sediment reduction, and absorption and adsorption of contaminants in soil and storm water (Brady and Weil, 1996). ' The Difference between SWFDs and SRDs Webster defines a filter as a porous material through which a fluid is passed to separate out matter in ' suspension. Compost filter socks are a new technology of an age-old, proven method to filter sediment and other pollutants from storm water runoff. Compost filter socks use one of nature's proven filtration devices (compost) in a contained system (sock) so compost filter socks can be used in a wider variety of ' contemporary storm water filtration and sediment control applications. Traditional sediment retention I devices (SRDs) only remove sediment from storm water(and therefore only the pollutants attached to sediment particles)by temporarily damming stormwater runoff to allow solids to settle— like a ' miniature sediment pond. Compost filter socks are a stormwater filtration device(SWFD)which allows water to flow through a porous matrix to separate sediment(same as SRDs) and other chemical pollutants that become soluble and/or migrate in storm water, including hydrocarbons, excess nutrients ' from fertilizers and manures, and some heavy metals—without temporarily damming the flow of stormwater runoff. Compost filter socks are more than just sediment retention devices they are stormwater filtration devices. The Advantages and Benefits of Stormwater Filtration Devices SRDs rely on ponding of stormwater to allow eroded soil in the form of suspended solids to settle, 1 ' whereas SWFDs actually filter the moving water with significantly less ponding, creating higher flow ; through rates and less hydraulic pressure behind the compost filter sock than traditional SRDs. The increase in hydraulic pressure from stormwater is what often leads to failure of SRDs(and poor ' ' installation), unlike SWFDs like compost filter socks. High ponding characteristic to SRDs, caused by low flow through rates and minor sediment clogging of their pores, is why engineers (as designers) and manufacturers of SRDs have continually increased their effective height—because the hydraulic head it ' creates often spills over the device. Compost filter socks and SWFDs are not designed to pond moving ' storm water, but to allow the water to flow through its three dimensional matrix and `filter' the water as i it moves through the sock. Traditional SRDs rely on blinding sediment concentrated runoff that flows to ' the device, as this occurs the hydraulic pressure increases significantly and will eventually push over, go under, or around the SRD. Compost filter socks, based on private and university research though particle size analysis and distribution, will not pond water as fast, thus relieving hydraulic pressure and the propensity for failure. Naturally, fast moving and high volume storm runoff is slowed by compost ' filter socks and sediment will accumulate on the up-slope side of the compost filter sock -as well as within the three dimensional filter.

More Advantages of Compost Filter Socks Compost filter media within compost filter socks can be customized through particle size distribution to allow for high flow rate conditions or low flow conditions. Compost generally weighs about 1000 to ' 1200 lbs per cubic yard of material. One cubic yard of compost generally fills 27 linear feet of 12 in compost filter sock and 12 linear feet of 18 in compost filter sock. At this rate, a 12 in filter sock weighs approximately 45 lbs per linear foot and an 18 in sock weighs about 100 lbs per linear foot—not exactly ' the lightest tool in the sediment control toolbox. The weight of compost filter socks alone makes them very resistant to movement from storm water runoff, particularly when installed and staked correctly. Additionally, compost filter socks that get run over by vehicles or heavy equipment will still filter storm ' water (to a diminished degree) until it is repaired, unlike most two dimensional SRDs that are rendered useless when run over by a vehicle. Finally, according some ecologists compost filter socks likely have less of an impact on wildlife migration patterns than silt fence, since compost filter socks can be easily ' scaled or traversed by terrestrial fauna, whereas silt fence is the equivalent of a wall to all terrestrial bound wildlife. i Support from Research Literature—the scientific facts A review of the scientific university and government agency research literature provides further evidence of the efficacy and environmental benefits compost and compost filter socks provide in j ' sediment control and stormwater management. i Simulated Rainfall vs Simulated Runoff ' As demonstrated by decades of stormwater runoff and soil erosion research conducted by universities, government agencies, and private industry the best way test soil erosion control devices of any kind is under natural rainfall and/or simulated rainfall conditions. Although simulated runoff tests can be ' valuable they leave out very important processes that occur naturally under rain generating runoff conditions. Only natural rainfall and specifically calibrated rain simulators can provide total and evenly j distributed water over a soil surface. The hydraulic force of rain impact affects the soil surface structure and soil aggregates (which effects runoff movement over, through, and into the soil -in addition to the soils capacity to hold water), and the rain drops explosive impact detaches soil particles (along with the action of runoff) and sends these particles in all directions it. In addition,rainfall often creates runoff ' simultaneously and uniformly across the soil surface area(Brady and Weil, 1996)—unlike runoff simulation studies; while the explosive and damaging impact to the soil surface helps to create the areas where rills will form from/with sheet flow of stormwater. In fact, soil is primarily detached by rainfall impact not runoff(Risse, 1999). In addition, the rainfall impact pulverizes soil particles and soil aggregates and thus creates more particles suspended in runoff water(i.e. greater suspended solids); these soil particles and aggregates are of a slightly different size and shape—notably smaller and therefore harder for SRDs and SWFDs to trap. This is a natural process and is not simulated in studies that only apply runoff without rainfall. In addition,runoff simulated studies rarely take into account the behavior of natural runoff. Runoff normally starts in very slow sheet flow dispersed evenly both FILTREXXT" Internmional L.L.C. 75481 Grafton Eastern Road• Grafton OH USA 44044 •"rel: 440-926-KA1 •Fax: 440.926.4021 • Mobile: 330-350-1706 !

THE CERTIFIED STANDARD P�1Ft IN EROSION CONTROL ! horizontally and vertically on a slope (not just as a source from the shoulder), as rainfall continues runoff ! rate and velocity normally increases creating interrill and rill erosion, and concentrated rills and ' channels (partially caused by the impact of the rain on the soil)which gradually increase as the rain continues. Additionally, rainfall (natural or simulated)naturally impacts the SRD or SWFD by the pounding action and corrosive effects of wind and water. The rainfall itself(aside from the runoff) can ' contribute to the undermining of a SRD or SWFD. Do not forget that in a rainstorm, the rain falls everywhere, and where SRDs disturb the soil surface as a requirement for installation (silt fence itself can be considered a soil disturbing activity),the rainfall that falls near and around the SRD will create a ' disproportionate amount of sediment— and the erosion on the down slope side of the SRD will go unchecked and in simulated runoffstudies unsampled. SWFDs such as compost filter socks do not disturb the soil surface upon installation. ' In studies that seek to scientifically evaluate SRDs and SWFDs a controlled area is necessary(often using borders to prevent run-on, effectively creating a watershed)to determine the calculable and ' probable or improbable effectiveness (through statistical significance and probability) of a device over a specific area that is receiving a prescribed (or measurable)quantity of rain water. Studies that do not employ these methods are considered demonstration sites and are not scientifically reputable projects. j ' University published runoff and erosion research studies have been conducted in plots as small as one square meter, and slope length is less of a factor than slope steepness (Brady and Weil, 1996). Field studies that only use simulated runoff do not replicate the natural conditions that occur in rainstorms that ' generate runoff and therefore are not as reliable for testing the effectiveness and efficacy of SRDs and SWFDs used in storm runoff applications. i ' Peer-reviewed Scientific Research Supports Compost and Mulch ? as a Storm water Filtration Device(SWFD) In independent field research conducted in Portland, Oregon by CH2M Hill, the Portland Metropolitan ' Services District, and W&H Pacific evaluating SWFDs and SRDs under natural rainfall (5 storm events) on 34% slopes 9 ft wide by 32 ft long found that compost SWFDs had 92%less total suspended solids ! (TSS), 73% less total P, and less metals in sediment concentrated runoff compared to 36 in silt fence ' (Stewart et al., 1993). In independent field research conducted by the University of Connecticut and the New England ' Transportation Consortium comparing the performance of erosion control and SRDs on slopes 5 ft wide by 30 ft long under 11 natural rainfall events reported the following: During a3/4 in. storm event hay bales lost approximately 300 g of solids (total load), silt fence 50 g, and the mulch filtration device 10 g. i During a 4.35 in storm event silt fence lost approximately 3200 g solids,hay bales 2900 g, and the mulch filtration device 250 g. The percent of sediment passing through the SRD/FDs as a ratio to bare soil were: hay bale 2.02, silt fence 1.63, mulch filtration device 0.20. On average, the silt fence and hay ' bale released an order of magnitude more sediment than the mulch filtration device (Demars et al, 2000). In a two year field study conducting by a team of soil scientists, engineers, and ecologists at The j ' University of Georgia comparing the environmental performance of compost and mulch erosion control and SWFDs to industry standard practices and SRDs on construction sites reported the following results. Under a series of storm events averaging 3.1 in/hr for one hour duration(equivalent to a 50 yr 1 j FILTRE}ik'*' International L.L.C, � 35431 Grahop Fa,�tern Road • Grafton OH USA 44444 -Tel: 440-926-8041 • Fax: 440.926.4021 - %lobile: 330-350-1706 ' Web: www.filirexxxom • Finail: info@filtrexxxorn i ri THE CERTIFIED STANDARD IN EROSION CONTROL i hr storm event for Athens, GA)mulch filtration devices had lower total sediment loads than silt fence j and averaged over all storm events mulch filtration devices had 35% less TS than silt fence. When the ' researchers compared the system of yard waste compost to industry standard practices (silt fence with hydroseed), the compost system had nearly 5 times less sediment loss, 27% less runoff, 2.5 times more time until before runoff commencement, 35%more time until peak runoff rates were achieved, 2.5 times less total nitrogen loss, 8 times less nitrate nitrogen loss, 6 times less total phosphorus loss, and 6 times less bioavailable phosphorus loss (Faucette, 2004). ' Independent laboratory testing with compost based Filtrexx Filter Media TM used in compost filter socks at the Soil Control Lab in Watsonville, CA has shown that this tool consistently removes total solids (TS) from simulated stormwater runoff on 3:1 slopes. Out of 27 trials conducted with compost filter ' socks, TS concentrations were reduced between 95 and 99%. In addition, flow through rates of 20-25 gallons/linear foot/minute of the compost filter socks were regularly achieved without diminished sediment and'/or pollutant removal rates. As a comparison, flow through rates for silt fence subject to high sediment concentrated runoff is 0.3 gal/linear ft/min and for clean water under lab conditions is 10 gal/linear ft/min according to the US ' EPA National Pollution Discharge Elimination System(2004). The US EPA goes on to say that silt fence should only be used where low level stormwater sheet flow is anticipated (2004). The US EPA also states the effectiveness ranges for silt fence constructed of filter fabric that are properly installed ' and well maintained are: silt-clay-loam removal = 0 to 20 %[typically the suspended solids fraction in water] and silt loam 50 to 80%"(2004). As stated earlier, compost is classified as a stormwater filtration device (SWFD) instead of a traditional { ' sediment retention device (SRD)because it functions to remove other pollutants in addition to sediment from stormwater runoff. According to the US EPA(1998) compost has been shown to degrade the ' following contaminants under controlled conditions and/or in field research programs: petroleum hydrocarbons (gasoline,diesel fuel,jet fuel, oil, grease), polynuclear aromatic hydrocarbons (wood preservatives,refinery wastes, coal gasification wastes), pesticides (herbicides and insecticides), and ' explosives (TNT, RDX, nitrocellulose). Petroleum contaminated areas amended with compost exhibited degradation rates of 375 mg kg-'/day compared to only 40 mg kg-'/day without compost (Stegmann et al, 1991 and Hupe et al, 1996). At the rate exhibited by the compost amended areas,typical petroleum t hydrocarbon contaminated soils (normal range is between 5,000 to 20,000 mg kg-1)would be completely degraded in 14 to 60 days (USEPA, 1998). In fact, hydrocarbon degrading microorganisms are often isolated from compost and used to inoculate bioremediation projects (Civilini et al, 1996 and Castaldi et ' al, 1995). Independent laboratory testing with compost based Filtrexx Filter MediaTM at the Soil Control Lab in ' Watsonville, CA has shown that this material can remove petroleum hydrocarbons (as motor oil) from simulated runoff at consistently high percentage rates. Out of 32 independent tests with motor oil concentrations in water between 100 and 1700 mg L-1, compost based filter media removed an average ' of 87% of the motor oil concentration in stormwater, while 20 of the 32 composts removed greater than 95%of the motor oil concentration in the simulated stormwater runoff.

The objective of this analysis is to show that the net peak rate and volume of stormwater discharge from Y P 9 the site in the Proposed Conditions will be equal to or less than the discharge under the Existing Conditions for the two, ten, and one hundred year rainfall events. Accordingly, development of the site as it pertains to stormwater runoff will not adversely impact adjacent or downgradient properties.

Soils within the construction limits is predominately Hinckley, loamy sand within the A hydraulic group. ' POINT OF ANALYSIS This entire project site is located within the Forest River watershed. The analysis rpoint is the river. 2 PROJECT DESCRIPTION The proposed project includes demolishing the incinerator building, capping the C\ landfill, building a new transfer station, paving access drives, loading and parking areas. It also includes constructing an area to allow for yard waste transfer. For the land fill site, stormwater will be collected in a system of catchbasins and pipes, routed through a water quality unit (Stormceptor) to obtain 80% TSS removal and be discharged to the Forest River. For the yard waste transfer site, the entire area will be surrounded by a vegetated treatment swale. Stormwater will sheet flow off pavement areas and be collected, treated and infiltrate in the swale. This will ' mitigate the impacts associated with the addition of impervious area. Standards for peak rate of runoff, infiltrations and water quality will be met with the design as proposed. COMMENTS AND CONCLUSIONS ' This analysis has demonstrated that there will be no measurable increase in peak ' rate of stormwater runoff or stormwater runoff volume due to the proposed development of this site. The proposed stormwater management system has been designed in accordance with DEP's Stormwater Management Policy and will be a significant improvement over the exiting condition. Although any site construction can impact local hydrology and water quality, the plans as presented incorporate many design features intended to mitigate adverse effects to downgradient wetlands and aquifers. 3 1 SUMMARY OF PEAK RATE OF STORMWATER RUNOFF Salem Landfill, Salem MA Peak Flows in cfs Storm Event: Exist Prop 2 Year 8.3 5.9 10 Year 17.2 12.6 100 Year 31.4 23.5 i� BETA Group, Inc. 3/3/2008 Stormceptor CD Sizing Program United States Version 4.0.0 Project Details Project Salem Transfer Station Project# 3407 Location Salem Company BETA Group Date Mar.3,2008 Contact Phil Paradis Selected Rainfall Station Particle Size Distribution State Massachusetts Diam.(um) Percent(%) Spec.Gravity Name ROCKPORT1 ESE ID# 6977 20 20 1.30 Elev.(ft) 79 60 20 1.80 Latitude N 42 deg 39 min ' Longitude W 70 deg 36 min 150 20 2.20 400 20 2.65 Site Parameters 2000 20 2.65 Total Area(ac) 4.1 Imperviousness(%) 42 Impervious Area (ac) 1.72 ' Stormceptor Sizing Table ' Stormceptor Madel %Runoff Treated %TSS Removal STC 450 56 72 , STC 900 75 80 STC 1200 75 80 ' STC 1800 75 80 STC 2400 86 84 STC 3600 86 85 STC 4800 93 88 STC 6000 93 88 STC 7200 96 90 STC 11000 98 93 STC 13000 98 93 STC 16000 99 94 Comments RU:JWMATERIALS" Concrete Pipe Division STC 900 Precast Concrete Stormceptor Stormceptor (900 U.S. Gallon Capacity) p 32110 Frame and Cover Grade Adjusters to Suit Finished Grade 5" 24"0 Outlet 6"0 Oil Pipe F, 430"0 Port 6"0 Orifice ---jF J Plate 72"0 ° 6" a 7" 'Varies Stormceptor - - Insert - — - - — — _ Outlet - - Inlet / Outlet Inlet Weir --------- r 6"0 a PDr Orifice Plate ° 55" Access opening 6"0 Oil Min. opee (See note 42) Port Inlet Pipe 24"4Drop 8„ Oupplan VleW a a a 8., a 17 a n Section Thm Chamber Notes: 1.The Use Of Flexible Connection is Recommended at The Inlet and Outlet Where Applicable. 2.

Soils are ' assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. , The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly ' wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. , Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained ' soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist ' chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. ' Group D. Soils having a very slow infiltration rate (high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is ' for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

On behalf of Northside ' Carting, Inc. and the City of Salem, we have provided the following responses in bold text. Copies of the referenced documents are included as Attachments. t ➢ How will the material exposed during the process of day-li hting the river be handled? Will it be capped? The waste materials will be removed from the subject portion of the river and placed under the area to be capped to the east of the Forest River. All materials will be capped in accordance with the detail presented as Attachment A. ➢ New plans to reflect the removal of the 60 feet of culverted river. ' Reference is made to Attachment B. ➢ Width of the roadway leading to the rear of the site, proposed drop-off area for residents, can it accommodate two cars? The width or the roadway to the yard waste and recyclable drop-off area will be a minimum of 26 feet to accommodate two-way traffic and large vehicles used to ship the yard wastes and recyclables from the site. That change will be reflected ' in updated site plans to be submitted to the Commission. ➢ Detail of guardrails to be located along roadway leading to the rear of the site. ' Reference is made to the Details Sheet included as Attachment C. 1 Lincoln,RI Norwood,MA Rocky Hill,CT ' Ms. Carey Duques, Agent February 28, 2008 ' Page 2 of 3 ➢ Profile showing layers that make up the cap. Reference is made to the capping detail included as Attachment A. ➢ Concerns about existing catch basin(s) on site and procedure to discontinue it/them All existing catch basins will be removed and the associated drainage lines will either be crushed and placed under the cap of the landfill or removed and disposed of off-site. ' ➢ Location of proposed guardrails throughout entire site, retaining walls are noted but not guardrails. IReference is made to the Site Plan included as Attachment B which illustrates the location of the guard rail. ➢ Lack of curbs; how will cape cod berms hold up to the plows during winter; what is outlined in the O&M plan? The O&M Plan will include a provision for annual spring inspection and repair ' of any damaged sections of the Cape Cod berm. ➢ Phase II Comprehensive Site Assessment, mentioned that you could bring a map to ' the next meeting showing the location of the test pits. We have included to location plans for test borings (not test pits) as Attachments ' D and E. They illustrate the locations of all test borings taken at the site; copies of boring logs are included in the Appendix to this submittal. ' ➢ Section of property that is outside of the property line— How to handle? The City Solicitor has contacted the Property Owner (North Shore Self Storage) and a tentative agreement to execute a construction easement to allow site access for purposes of landfill closure has been reached. That agreement is currently under development and will be executed soon. Northside Carting, Inc. may, at its discretion, acquire that portion of the adjacent parcel after transfer of the City-owned property to Northside Carting, Inc. ' ➢ Final restoration plans, details about plantings, what and how restoration would occur along river bank and other sections of the site. No plantings will be permitted on any portions of the capped landfill and no other adjacent areas will be disturbed. The slopes of the landfill, including those along the river,will be re-seeded with a "slope mix" specifically developed with ' Ms. Carey Duques, Agent February 28, 2008 Page 3 of 3 deep rooted grasses that will hold the embankment from sloughing off to the river. Reference is also made to Attachment A. On the west side of the river, we will have an opportunity to provide indigenous ' plantings at the periphery of the site, but landscaping will be kept to a minimum. We trust that these responses adequately address the concerns of the Commission at this time. Please call me with any further questions or concerns. Very truly yours, BETA GROUP, INC. L Alan D.

(BETA) in 2000 on behalf of the City of Salem, Department of Public Works, for the v same property located at 12 Swampscott Road. The 2000 NOI resulted in an Order of Conditions (OOC) issued on July 27, 2000 (DEP File Number 64-308). That OOC, which expired in 2003, ' was invalidated in January 2008 at the request of the City, Northside Carting and BETA, as the work described in the NOI had never been started. The purpose of this NOI is to obtain an OOC to complete the work described in the 2000 NOI/OOC. ' The proposed work is also substantially the same as that contemplated by the City, Massachusetts Department of Environmental Protection(DEP), and Northside Carting (NSC, the ' operator of the facility) during negotiations of an Administrative Consent Order (ACO) and, subsequently, as part of Option 94 presented in BETA's Corrective Action Alternatives Analysis (CAAA) Report as approved by DEP in a conditional letter of approval dated April 20, 2005. ' The majority of the work proposed under this NOI remains within the category of "limited project" as defined at 310 CMR 10.53(3). ' Demolition of Existing Building The former incinerator building (currently being used as part of the existing transfer station operations) will be demolished as part of the Site improvements. The demolition will include the ' building and smoke stack. The demolished incinerator building will be replaced by a new r transfer station building as described below. ' In accordance with the DEP letter dated April 20, 2005 regarding the conditional approval of the landfill CAAA, the construction and demolition (C&D) debris from the demolition of the incinerator will be used as backfill for the incinerator building foundation hole and to re-grade ' the area around the existing foundation. The landfill cap will subsequently be extended to include the transfer station foundation as part of the landfill closure design. A waiver of the local Demolition Delay Ordinance will be sought. Capping of Closed Landfill Landfill closure is defined as a Limited Project in accordance with 310 CMR 10.53(3)(p). The waste at the site consists of ash, C&D debris, and municipal solid waste. The contours of the ' proposed capped landfill will be designed such that slopes to the Forest River will not exceed three feet horizontal by one foot vertical (3:1). Retaining walls will be used in the central portion of the cap to allow the proposed layout of the driveway as shown on the attached schematic plan. ' The landfill cap is proposed to consist of re-grading of the existing soil cap to proposed grades, followed by installation of a flexible membrane liner (FML) of HDPE, or equivalent. The FML will be covered by a 12-inch sand drainage layer and a 12-inch layer of topsoil and turf. Note: ' A geotextile membrane with integral drainage layer may be installed in lieu of the sand drainage layer. After final placement of topsoil and grading to final elevations is completed, the surface of the ' entire landfill cap will be covered with jute erosion mats held in place with soil nails. An ' - 1 1 Notice oflntent 12 Swampscott Road, ' Salem,MA February 11,2008 ' approved meadow seed mix will be spread over the upper portions of the cap and a wetland seed mix will be used on the lower, river bank portions of the cap. ' Refer to the "Site Plan-East Side of Forest River" in Section N for limits of the proposed landfill cap. ' Construction of Transfer Station Building Construction ' The proposed new transfer station will include an enclosed metal building on a pile-supported poured-concrete foundation with proposed dimensions of approximately 75 feet by 100 feet. The new building footprint will not exceed by more than 10% the footprint of the current incinerator ' building. The building will be approximately two stories high(35 feet at the eaves). The building will contain two upper level truck bays designed for off-loading (dumping) waste into open top trailers parked immediately below in the lower level. A 1,500-square foot office and break room ' will also be included in the building. The construction of this proposed building will be permitted through a minor modification to the ' existing site assignment for this facility. Repaving The driveways associated with the new transfer station will be similar in layout to the existing ' paved driveways. All existing pavement will be removed and replaced as part of the transfer station upgrade. Additional paved driveways will be added to allow for the smooth flow of truck traffic within the site. Refer to the attached figure for a depiction of the paving planned for this project. 1. Amount of Paving currently at Transfer Station: 25,000 Square Feet ' 2. Total Area Proposed to be Paved: 43,000 Square Feet 3. Amount of Proposed Paving within Wetland Buffer Zone: 25,000 Square Feet 4. Amount of Proposed Paving Within Riverfront Area: 27,000 Square Feet Parking Lot Included within the totals listed above, a portion of the paved area at the transfer station will be used for parking - one area for employee parking and three parking spots for trucks used in the transfer station operations. Refer to the attached Site Plan in Section G for layout. ' Operations NSC proposes to operate the transfer station at a capacity of 400 tons per day. The waste will consist of construction and demolition debris, municipal solid waste, and commercial solid ' waste. Relocation of Leaf and Yard Waste Composting/Recycling Area ' Paving Limited project in accordance with 310 CMR 10.53(3)(e) The current leaf and yard waste composting area is an unpaved handling area that is used only by ' NSC trucks. In order to make this area useable by resident's automobiles, the travel lanes will be -2- Notice of Intent 12 Swampscott Road, ' Salem,MA February 11,2008 ' paved to the extent shown "Site Plan - West Side of Forest River" included in Section N. The paving will include an access road that will connect the leaf and yard waste composting/recycling area to the Transfer Station site, as well as to existing site access and ' egress points (curb cuts) to Swampscott Road. This access road meets one of the definitions of a limited project, i.e., "the construction and maintenance of a new roadway or driveway ...where reasonable alternative means of access from a public way to an upland area" of the site is ' unavailable. 1. Amount of Paving currently at Composting Area: 0 Square Feet ' 2. Total Area Proposed to be Paved: Yard Waste/Recyclables Area 9,400 Square Feet ' Connecting Roadway 9,800 Square Feet 3. Amount of Proposed Paving within Wetland Buffer Zone: 9,800 Square Feet ' 4. Amount of Proposed Paving within Riverfront Area: 19,200 Square Feet Concrete Block Push Walls t A 22,000+/- square foot area will be graded and leveled for the Yard Waste Drop-Off/Recycling Area. A push wall will be constructed of monolithic concrete blocks to facilitate loading of the leaf mulch and yard wastes for off-site transport. Note that the proposed Leaf and Yard Waste ' Composting/Recycling Area has been situated to minimize the amount of activity within the 100- foot buffer zone. Operation NSC proposes to continue the operation of the leaf and yard waste composting area on a 6-day per week, year round basis. Sunday hours will be added during three week periods in the spring and fall. ' Leaf and yard wastes will be loaded and shipped from the Site, as required. During periods of heavy usage, the leaf and yard wastes may be shipped as frequently as daily. However, during ' most times of the year, shipments will be on the order of one to four times a month. Site Improvements ' Partial Removal of Forest River Culvert The proposed plan includes the removal of approximately sixty (60) linear feet of the upstream portion of the concrete culvert that conveys the Forest River under the existing access road to the composting area located on the west side of the Site. The material excavated to allow removal of that portion of the culvert will be placed on-site within the limits of the waste and incorporated into the capped portion of the landfill. t Before any disturbance of soil and/or waste occurs, a continuous row of staked hay bales and silt fence will be installed along the water's edge. During any excavation along river bank, temporary silt curtains will be installed where the depth of the river makes their use possible. ' After the culvert removal is completed, the remaining material forming the banks of the Forest River will be landfill solid waste and/or ash and will thus be capped as part of the landfill closure. The pre-capping grade of the waste/ash will be altered such that (1) no slope is steeper than three horizontal to one vertical and (2) sufficient room is created to allow the placement of -3- Notice oflntent 12 Swampscott Road, 1 Salem,MA February 11,2008 ' the landfill cap (proposed to consist of a leveling layer of soil or sand, followed by flexible membrane liner constructed of HDPE, or equivalent, covered by a sand drainage layer and a 12- inch layer of topsoil and turf). As final grading and placement of topsoil to final elevations is completed, landfill slopes leading down to the Forest River will be covered with jute erosion mats held in place with soil nails. An approved wetland seed mix will be spread over the newly- created landfill cap. ' Removal of Debris from River Visible debris from the Forest River will be removed through the use of an extended boom on an ' excavator. The excavator will be located at the top of the embankment, so as to minimize damage during debris removal. The removed material will either be incorporated into the capped portion of the landfill or transported off-site for recycling or disposal. Storm Water Managementt ' The work proposed under this NOI is defined as a "Redevelopment' project because the site is already in use as a transfer station. In accordance with the revised Wetlands Protection Act Regulations, 310 CMR 10.05(6)(k), a redevelopment project is generally required to meet the storm water standards to the extent practical. Where applicable, a discussion of the means by which the project will meet these standards is provided below: ' No new storm water conveyances The project will not result in any new discharges of untreated storm water runoff, therefore, the project meets this standard. Peak Discharge Rates Peak flow rates will not increase as a result of this project, despite the additional paved surfaces. Therefore, there will be no adverse impact to the Forest River on the east side of the Forest River. The rate of runoff from the area west of the Forest River will actually be reduced due to construction of the proposed water quality swale. ' Loss of Annual Recharge to Groundwater ' Redevelopment will meet this standard to extent practicable. The project includes the capping of the landfill with approximately two feet of permeable material (grass, soil, and sand) over an impermeable liner. As a result, the soil portion of the cap is expected to absorb the majority or storm water that falls on it, with eventual discharge to the river after flowing through the sand drainage layer and the geotextile liner(if provided with integral drainage). In the leaf and yard waste composting / recycling area, storm water runoff from the newly- paved area will be directed to a perimeter drainage swale where the runoff will accumulate and percolate into the subsurface. ' Total Suspended Solids Reduction Redevelopment will meet pretreatment and structural best management practice requirements of this standard. The Operator will implement a program of periodic street sweeping (at least ' annually, with more frequent cleaning as required) to minimize solids accumulation in the Notice oflntent 12 Swampscott Road, ' Salem,MA February 11,2008 ' storm water conveyance system. To achieve the total suspended solids (TSS) reduction required under the current regulations, runoff from the east side of the site will be routed through a Stormceptor®prior to discharge to the Forest River. Source Control and Pollution Prevention ' During Construction - Because the proposed construction at the Site will impact more than one acre, a construction SWPPP will be prepared in accordance with the NPDES regulations. The SWPPP is required to provide for the minimization of construction- related storm water pollution by implementation of Best Management Practices (BMPs) such as site inspections, site stabilization (e.g., by vegetation or artificial erosion and sedimentation control), sediment traps and/or sediment basins, and velocity dissipation devices at discharge locations. Upon completion of the SWPPP, a Notice of Intent will be submitted to the U.S. Environmental Protection Agency for coverage under the EPA's ' Construction General Permit (CGP). BETA will prepare this plan prior to construction and will provide a copy to the Commission. During Operation - The Site is the location of category 5 (landfill) and category 6 ' (recycling facility) industrial activities, and as such is an "Industrial Facility" under U.S. EPA's National Pollutant Discharge Elimination System(NPDES) Industrial Storm water ' permit regulations. A Storm Water Pollution Prevention Plan (SWPPP) will be prepared to cover these operational activities, in accordance with the NPDES regulations. Prior to 2005, operators of industrial facilities submitted a Notice of Intent to the U.S. Environmental Protection Agency for coverage under the EPA's Multi-Sector General Permit (MSGP). However, the previous 2000 MSGP expired in October 2005 and the t replacement general permit has yet to be issued by EPA. In accordance with EPA's current guidance, BETA will prepare a SWPPP based on the 2000 MSGP requirements. The 2000 MSGP required BMPs be implement to minimize storm water pollution such ' as: improved housekeeping practices, regular site inspections, and prevention of non- storm water discharges, Submittal of a Notice of Intent will be required upon EPA's promulgation of the new MSGP. Storm Water Discharges Near Public Water Supply or to any Other Critical Area No public water supply or other critical areas have been identified at or in the vicinity of the ' Site. Construction Erosion, Sedimentation, and Pollution Prevention Plan BETA will prepare the required construction SWPPP as described above prior to construction and will provide a copy to the Commission. ' Long-Term O&M Plan BETA will prepare the required Long-Term O&M Plan, as described above, and will provide a copy to the Commission. ' -5- Notice oflntent 12 Swampscott Road, ' Salem,MA February 11,1008 Illicit Discharges The proposed redevelopment will not include the construction or continuance of any illicit discharges (i.e. floor drains, sanitary discharges, etc.). A direct connection to the City's sanitary sewer will be provided and any current subsurface sanitary systems will be decommissioned. Compatibility with Neighborhood ' During initial design activities, care was taken to locate the transfer station as far from residential areas as possible and to orient the building to shield area residents from day-to-day activities. To that end, the main access doors to the proposed transfer station are located on the northwest side of the building. Since that portion of the site is nestled into the embankment, most of the trucking activity will be screened from view and noise impacts to the neighborhood will be minimized. A layout of the proposed transfer station is illustrated on Figure 1 included in ' Section N. The layout of the main access drive off Swampscott Road has been modified to allow for more streamlined access to and from the scale house. Currently, larger vehicles sometimes create traffic delays while they negotiate the tight turning radius into the site as they approach from the north. ' We have also held informal meetings with City officials and Fafford Development residents and agreed to change the proposed color of the building to green in an effort to blend the facility with the environment. We are committed to continue to work with area residents to finalize the ' layout, design and features of the transfer station to minimize any adverse impacts to the neighborhood. On behalf of the City and NSC, BETA has performed significant site investigations and monitoring, including groundwater sampling and analyses, subsurface investigations, evaluation of landfill closure alternatives and initial design of a new transfer station. Those efforts ' culminated in the submission of a Corrective Action Alternatives Analysis (CAAA) Report that was submitted to the DEP in March 2005. In April 2005, MADEP issued a conditional approval letter that involves the planned demolition of the existing incinerator building and stack and ' construction of a new 400-ton per day transfer station. 1 1 NOTICE OF INTENT FORM 1 1 1 1 1 1 1 1 1 1 1 1 1 Massachusetts Department of Environmental Protection Provided by DEP: ' 1 , Bureau of Resource Protection - Wetlands DEP File Number WPA Form 3 - Notice of Intent Document Transaction Number Massachusetts Wetlands Protection Act M.G.L. c. 131, §40 City/town henfanT.

Soils are ' assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation,are thoroughly wet,and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups(A, B, C, and D)and three dual classes(A/D, BID, and CID).The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep,well drained to excessively drained sands or gravelly sands.These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet.These consist chiefly of moderately deep or deep,moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture.These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet.These consist ' chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate(high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer ' at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group(AID, BID, or CID),the first letter is for drained areas and the second is for undrained areas.Only the soils that in their natural condition are in group D are assigned to dual classes.

However, minor temporary alteration of the wetland resource area (450+/- square feet) will be required to accommodate installation of the landfill cap. For mitigation, at the Commission's option, we propose to ' eliminate the 60+/-foot upstream section of the existing culvert, thereby creating approximately 600 square feet of resource area to compensate for the temporary ' alteration of the river's edge during construction of the cap. ➢ Protection of Rare Species 10.58(4)(b) The Site has not been identified as the habitat of any rare species and, therefore, ' meets this performance standard. ➢ Practicable and Substantially Equivalent Economic Analysis 10.58(4)(c) ' The Site is an existing landfill that is required to be closed under MassDEP Solid Waste Regulations at 310 CMR 19.00. The City of Salem has entered into an ' Administrative Consent Order with MassDEP which provides for certain deadlines to be met to achieve closure. There are no viable alternatives to closure of the landfill. In addition, the site has a Site Assignment under DEP Solid waste ' regulations and a minor modification to the Site Assignment will be submitted to the Board of Health No other site in Salem is currently permitted to serve as a transfer station. ➢ No Significant Adverse Impact 10.58(4)(d) The purposes of the work proposed under this NOI are as follows: • To terminate current composting operations within the Riverfront Area; ' . To complete the required landfill closure in accordance with applicable state regulations; To replace the existing incinerator building (retrofitted for use as a transfer ' station) with a new transfer station; and To install new recycling and yard waste composting facilities for use by ' residents of the City of Salem. ' By achieving these purposes, the project will have a netosu itive impact on the riverfront area. The proposed construction will include landfill capping and slope 1 — 1 — Notice oflnlent 11 Swampscott Road, ' Salem,MA February 11,2008 ' stabilization provisions that will substantially reduce the current landfill leachate(storm water infiltrating through the landfill) entering the Forest River, site erosion and tongoing siltation of the river. In addition, wastes and debris currently located along the river's edge will be removed and incorporated into closure of the landfill. All of these activities will result in a significant improvement in the water quality of the Forest River at and downstream of the Site. ' In order to minimize the impact of the work to the wetlands and riverfront, the Applicants propose to remove the upstream portion of the existing culvert so that approximately 60 linear feet of the river is returned to open channel flow. All slopes ' along the river will be stabilized with dumped rip-rap and, if necessary, geotextile fabric and stone for stability. In addition, the yard waste drop-off and recycling area ' has been located as far away from the resource areas as possible. Site Specific Information ' The following site-specific information is provided to show that the riverfront area of the Site will not have an adverse effect on the following interests: ' ➢ Private or Public Water Supplies There are no public water supplies within the City of Salem. The water supply for the City of Salem is provided from surface water reservoirs operated by the Massachusetts Water Resources Authority, none of whose reservoirs are located ' in the City of Salem. No private water supplies are know to exist within a half- mile radius if the Site. Therefore, it is BETA's opinion that the proposed project will not have an adverse effect on this interest. ' ➢ Groundwater BETA has reviewed the on-line MassGIS Priority Resource Map which shows ' that the site is not within or within the vicinity of a mapped Zone II or interim wellhead protection area, productive or potentially productive aquifer, or other area indicating the current or future potential use of the Site as a groundwater supply. Therefore, it is BETA's opinion that the proposed project will not have an adverse effect on this interest. ➢ Flood Control ' BETA has reviewed the August 15, 1985 Flood Insurance Rate Map published by the Federal Emergency Management Agency National Flood Insurance Program Map number 250102 0005 B shows the site and area within at least a 2,000-foot ' radius to be in Zone C — an area of minimal flooding. On the basis of this ' — 2 1 Notice oflntent 12 Swampscott Road, ' Salem,MA February 11,2008 ' classification, it is BETA's opinion that the proposed project will not have an adverse effect on this interest. Also note that the proposed design of the landfill cap includes the removal of visible waste material within the river. The purpose of this removal is to enhance ' the aesthetics of the river and to increase the stability at the toe of the landfill cap. The effect of the removal of this material, along with removal of the upsteam ' portion of the existing culvert, will result in a slight increase in flood storage capacity at the Site. ' Careful consideration will also be given to clearing the existing culvert of obstructions. Currently, due to debris accumulation, the culvert appears to be ' serving as a controlled orifice outlet for the upstream reach of the river. The obstructed culvert appears to effectively attenuate peak rates of storm water runoff to downstream areas. ' ➢ Land Containing Shellfish The Site is approximately two miles from the Atlantic Ocean. Surface water at the ' Site consists of a very small river (Forest River) and a portion of an associated unnamed pond. Neither of these surface water bodies are tidally influenced or support any shellfish. Therefore, it is BETA's opinion that the proposed project will not have an adverse effect on this interest. 1 Other The remaining interests may be affected by the proposed project: • Pollution Prevention; • Prevention of storm damage; ' Fisheries; and • Wildlife habitat. For each of these interests, BETA presents the evidence in the following sections that there are no practicable and substantially equivalent economic alternatives to the ' proposed project with less adverse effects on the [remaining] interests listed in M.G.L. c.131 § 40 (i.e., flood control, prevention of storm damage, prevention of pollution, and wildlife habitat) and that the work, including proposed mitigation, will have no ' significant adverse impact on the riverfront area to protect the interests identified in 1 ' —3— Notice oflntent 12 Swampscott Road, Salem,MA February 11,2008 M.G.L. c.131 § 40. ' ➢ Prevent Pollution Approximately 60 %of the Site is located within the Riverfront Area of the Forest ' River. The Site contains an operating transfer station. The purpose of the work proposed to be performed under the anticipated OOC will result in the minimization of leachate entering the Forest River (by capping), mitigation of ' debris currently in the river (by its removal), and reduction of siltation and erosion into the river (by the capping and slope stabilization). Each of these proposed ' activities will result in an improvement in the water quality of the Forest River at the Site. ' It is BETA's opinion that the work will have no adverse impact on the riverfront area's ability to protect the interest of pollution prevention identified in M.G.L. 0.131 § 40. Conversely, completion of the work proposed under this NOI will ' significantly curtail leachate migration to the Forest River and greatly enhance the interest of pollution prevention. ' ➢ Prevent Storm Damage For similar reasons to those described above, the permanent closure of the ' existing landfill and the rehabilitation of the transfer station activities will improve Site conditions including the prevention of storm damage. Currently, ' portions of the Site have minimal or no vegetative cover and erosion of Site soil and/or waste into the Forest River may be occurring during storm events. The presence of a properly capped and vegetated landfill cover will prevent such erosion, and act to absorb stormwater, minimizing direct overland flow of stormwater into the river. Wildlife Habitat In addition to the environmental improvements to the Forest River and its banks ' described above, the project will provide a permanent cap to the solid waste and ash currently in-place at the Site. The cap will be finished with topsoil and seeded with a meadow seed mix. The presence of the cap will prevent exposure to the ' waste and ash and substitute grass and other low, shallow-rooted vegetation for the exposed soil and brush currently at the site. It is BETA'S opinion that the work ' will have no significant adverse impact on the riverfront area's ability to protect the interest of wildlife habitat identified in M.G.L. c.131 § 40. In fact, completion of the work proposed under this NOI will likely increase the ability of the ' riverfront area at the Site to protect the interest of wildlife. It is BETA'S ' —4— Notice oflntent 11 Swampscott Road, Salem,MA February 11,2008 experience that capped landfills provide habitat for numerous plant and animal species including birds and small ground animals. These species typically will ' return or expand their habitat into a capped landfill shortly after the completion of construction. ➢ Fisheries The Site is approximately two miles from the Atlantic Ocean. Surface water at the Site is at an elevation of approximately 70 feet above sea level and consists of a small river (Forest River) and a portion of an associated unnamed pond. Neither of these surface water bodies is tidally influenced. According to the October 4, 2001 USGS quadrangle for the area, the Forest River flows into Thompson's Meadow approximately V2-mile southeast of the Site before discharging onto Salem Harbor. No river channel is shown within Thompson's Meadow. As previously described, the presence of the cap will prevent exposure to the waste and ash and will greatly reduce runoff from the landfill into the Forest River. It is BETA's opinion that the work will have no significant adverse impact on the Forest River and will likely increase the ability of the riverfront area to protect the interest of fisheries identified in M.G.L. c.131 § 40. t r —5— 1 � OPERATION & MAINTENANCE PLAN 1 1 1 1 1 1 1 ' 1 1 1 i 1 1 1 1 1 1 1 1 1 OPERATION & MAINTENANCE PLAN 1 FOR THE STORMWATER SYSTEMS FOR 1 Closure of the Salem Landfill & 1 Operation of the Salem Transfer Station 12 Swampscott Road 1 Salem, Massachusetts 1 Prepared For: 1 City of Salem 93 Washington Street Salem, Massachusetts 01890 1 and 1 Northside Carting, Inc. 210 Holt Road North Andover, Massachusetts 01845 1 1 1 1 BETA Group, Inc.

' General Information ' Project Name: 12 Swampscott Road Type of Development: Landfill Closure and Transfer Station Address: 12 Swampscott Road, Salem, MA 1 Owner: City of Salem ' Address: 93 Washington Street, Salem, MA 01970 Operator: Northside Carting, Inc. Address: 210 Holt Road,North Andover, MA 01845 tSite Manager: Kevin Thomson tConstruction Activities 1. Contact the Conservation Commission at least three(3) days prior to start of ' construction. 2. Install a hay bale and silt fence at the periphery of all work areas, except where ' removal of wastes from the Forest River and/or wetlands areas is actively being performed. Temporary measures shall be undertaken during non-working hours, or during runoff periods, to prevent migration of fines in runoff from the construction site to the wetlands and/or the Forest River. 3. The Site Contractor shall disturb the minimum area necessary, with particular ' emphasis on the western portion of the site where the yard waste drop-off and recycling facilities will be located. ' 4. Erosion and sedimentation control measures shall be maintained for the duration of the project. ' 5. During landfill closure activities involving disturbance within the Forest River and the immediately adjacent wetlands, a floating silt curtain will be installed to promote settlement of any suspended solids, so as to significantly minimize the ' migration of fines to the river and downstream areas. Closed cells will be created 1 ' for each work azeanp for t0 disturbance of wastes within the river and the immediately adjacent wetland area. ' 6. Erosion control fabric(jute) shall be installed on the finished grade of all slopes greater that I%. The area of surface disturbance at any time during construction without erosion control fabric shall be 1 acre(43,560 so. 7. The entire project area shall be swept upon completion of construction and prior to removal of the erosion control devices. ' Post-Development Activities 1. Pavement: Paved areas shall be swept annually, on or prior to April 1, to remove excess sand and/or residuals. This will result in a decreased sediment load that the drainage system will have to remove from the runoff. Use of salt for de-icing purposes on the roadway is prohibited within 100 feet of any resource area. ' 2. Catch Basins: Catch basin grates shall be checked periodically and following heavy rainfalls to verify that the inlet openings are not clogged by debris. Debris ' shall be removed from the grates. Catch basin sumps shall be inspected and cleaned of all accumulated debris each spring, after the winter sanding season. Catch basins with hoods shall be inspected to check for build-up and any ' obstructions. All material removed from catch basins shall be disposed of in accordance with all applicable regulations. ' 3. Stormceptor: The stonnceptor shall be inspected annually. Debris and accumulated sediment shall be removed and disposed of all in accordance with applicable local, state, and federal guidelines and regulations. t4. Water Quality Swale: The water quality swale around the proposed recyclable collection and yard waste drop-off areas shall be inspected annually. Any debris and accumulated sediment shall be removed and disposed of in accordance with applicable local, state, and federal guidelines and regulations. t 5. Maintenance Responsibilities: All post construction maintenance activities should be documented and kept on file and made available to the Conservation Commission upon request. All post construction maintenance activities shall survive the Order of Conditions and shall run with the title of the property. Every effort shall be made to work with the Conservation Commission and the abutters regarding maintenance and operation of stonnwater management system components. All structural BMP's installed at this site shall be owned and maintained by the owner of the property and shall run with the title of the property. 1 ' 3 ' SITE PHOTOGRAPHS ' i \ LEGEND: \ \ / PHOTOGRAPH LOCATION REFERENCE / ---------- N/F CITY OF SALEM / MAP 7 PARCEL 68 / - -- ""-- \ 9.20 ACRES \ / / ___ ____,`,• I_'1 \ Bp _1 12 �- .]�. __- __ ___ _ _ _ __ _ ______________________________ ___ _ _ _'0 :'!,. ,•-.

The application was prepared on your behalf by BETA Group,Inc.,-Norwood,Massachusetts. ' The recommended alternative provides for: - 1. Demolition of the existing transfer station(former incinerator)and replacement with a new suncture designed-for.use as a transferstation,, ' 2.

The Department concurs that the C&D ' materials-both from demolition of the existing building and from relocation of materials from the culvert area- may be used to backfill the building foundation hole and re-grade the area around the existing foundation. ' The application proposes to effect the use of the C&D debris as backfill pursuant to a Beneficial Use Determination(a BUD,310 CMR 19.060). The Department has determined that a BUD is not the appropriate mechanism for the effecting the use of the C&D as proposed by this project. In consideration of the origin and character of the C&D debris,the debris must be placed as part of the waste materials in the landfill,and the landfill cap extended to include the transfer station foundation. The Department will entertain disposal of the C&D materials in this manner as an integral component of the site remediation and landfill closure design. Based on the site use history and the soil conditions identified by the Comprehensive Site Assessment (CSA),the Department has determined that the construction of the salt shed does not require Department approval. The Department approves the CAAA and concurs with the selection of Option 4 for the design of closure of the landfill subject to the following conditions: 1. TL,closure design shall: ' a. Extend the limits of the cap to cover the C&D waste materials. In accomplishing this extension of the cap,either the FML may be extended under the new building with the FML and related layers designed to accommodate the loads,or the building foundation I shall be integrated into the impervious layer of the cap. ' b. Design the new building foundation to protect the building and its occupants from explosive gases. ' 2. The Corrective Action Design(CAD,i.e.the closure plans)application shall be signed by the appropriate official of the City of Salem. Reports,plans,etc.,shall be signed and sealed by the engiueer of record. Each shall include certification pursuant to 310 CMR 19.011,as required. ' 3. The Department reserves the right to amend,modify,suspend or revoke this approval as necessary,to protect the public health, safety or the environment, or as otherwise necessary to insure compliance vrith applicable law and/or regulation. ' 4. The City shall obtain and comply with the requirements of all applicable state,federal and local laws, regulations, and permits. Concurrently with submitting the CAD application the City shall submit documentation that the applications for such other permits and approvals as may be required have been applied for. 5. In consideration of the commercial operating nature of the transfer station by Northside Carting ' Inc. and the interdependence of the reconstruction of the transfer station on the corrective action design,the Department's review ofthe CAD shall not be subject to the exemption from application fees granted to municipalities. The application shall be subject to payment of the applicable fees ' for privately owned/operated facilities as established at 310 CMR 4.00. 6. The Department reserves the option to requireNorthsideCarling,Inc.to obtain a permit,issued to i�Toj thside Cat ting,Inc.,for future operation of the facility,and/or otherwise pay an annual co=mpliance fee as applicable to privately operated facilities.

Option 1 is rejected as the results ofthe Comprehensive Site Assessment(CSA) did not indicate a need. ' The City's engineers recommend the selection of Option 4 for the closure of the landfill: ' Under Option 3: The axisting landfill would be capped with a low permeability soil or FML cap. ' * All waste would be retained within the existing waste limits. * The River Front of the Forest River would be remediated by: 1. excavating the waste from the edge of the river, II. constructing a concrete bin type retaining wall along the edge of the river, iii. backfilling the retaining wall with the excavated waste. ' . This option would not make any:changes to the existing transfer station or other improvements to the site outside of the existing limits waste. ' Option describes using an FML to construct the cap along the slopes facing the river. ' As described the F-MI,would be placed at a.gradieut of 3:1, and excavated waste would Ve "stored"behind.a retaining wall constructed next to:the river. The Department assumes it is meant that the excavated waste will be used as permanent backfillbehind . the retaining.wall. ' The described River Front remediation would result in waste materials being.placed above the cap, This element of the design does not comply with minimal requirements +. ' for the capping of the waste material. However,the design is amenable to alteration to correct this deficiency. Under Option 4 the landfill would be capped with a low permeability soil or FML cap as included at Option In addition: * The old incinerator building(of which part is used as the existing transfer ' station)would be razed. , . . _ s1f5D409is.doc 04/14/05 t ' FACT SHEET File Number: W062414 t Salem Landfill & Transfer Station Page 4 of 4 Corrective Actions Alternatives Analysis ' * The River Front of the Forest River would be remediated by excavating waste from along the river and regarding the landfill slope, (currently varying from 1:1 to 2:1)to a gradient of 3:1. Forest River will be further remediated by removal of the C&D waste ' materials from the area of the culvert and reconstructing the river crossing with clean fill. * The C&D debris from razing the incinerator, along with the waste ' excavated from the River Front would be used to backfill the area of the incinerator building. * A new transfer station,with access driveways and aprons,would be t constructed. * A new salt shed would be constructed on the portion of the property on the opposite side of the Forest River(the area currently used for the Town's ' leaf&yard waste composting area.). As proposed the new building would retain the same setback from the street side property line as the current building (circa 40 feet). Option 4 proposes to use the C&D debris and excavated waste as fill under the new, transfer station pursuant to a Beneficial Use Determination(BUD). This type of approval will not likely appropriate. However, the design will likely be amenable to extension of the waste area and crap to beneath the new transfer station building. Option 4 includes construction of a new salt shed on the property. As identified in the plans available at this time, the area where the salt shed is proposed has not been used for solid waste (ash, MSW) disposal. The area is currently being used for leaf&yard waste ' composting- an activity exempt pursuant to 310 CMR 16.05(4)(b). As described in the CSA and noted on the plan included with the CAAA,waste disposal at the site was limited principally to the portion of the site east of Forest River. Some construction& ' demolition waste (C&D debris) disposal also occurred within the immediate vicinity of the Forest River as part of establishing access across the Forest River to the portion of the west of the river- an approximately 160 foot reach of the river was placed into a culvert and the river channel at the culvert was filled with C&D debris materials. The Departrient, therefore, deems the portion of the site west of the Forest River(not ' including the area of C&D disposal) to be a separate and distinct area from the waste disposal area of the site. Therefore, the area where the salt shed is to be located is not subject to review and approval as a post closure use for the purpose of constructing a salt ! ' shed as proposed.

(NSC) since September 1994. A portion of the incinerator building, located on the northeastern portion of the site and originally constructed in 1963, was converted to the current transfer station in 1975. The landfill portion of the Site is located on the eastern portion of the ' property. A yard waste composting area, currently operated on the southwestern portion of the property, is separated from the landfill/transfer station portion of the property by the Forest River, which bisects the site. A roadway was built over a portion of the Forest River by the City ' of Salem to connect the two portions of the property circa 1969. Historically, wastes disposed of at the incinerator included municipal solid waste (MSW) and construction and demolition (C&D) debris. Due to a public need circa 1994, a portion of the incinerator building was converted to operation as a Transfer Station by NSC. Since that time, wastes transferred from the site have been almost exclusively construction and demolition debris, ' with only minimal amounts of MSW. A more complete discussion of the background and compliance history of the site is available in ' the CAAA Report prepared by BETA and submitted to the MA DEP in March 2005. Proposed Re-Use for 12 Swampscott Road ' On behalf of NSC, BETA performed significant site investigations and landfill monitoring, including groundwater sampling and analyses, subsurface investigations, evaluation of landfill closure alternatives and initial design of a new transfer station. Those efforts culminated in the ' submission of a Corrective Action Alternatives Analysis (CAAA) Report that was submitted to the DEP in March 2005. In April 2005, MADEP issued a conditional approval letter that involves the planned demolition of the existing incinerator building and stack and construction of ' a new 400-ton per day transfer station. The proposed layout of the site is illustrated on Figure 1 included in the Appendices. ' The proposed re-use of 12 Swampscott Road is substantially the same as that contemplated by the City, MADEP and NSC during negotiations of an Administrative Consent Order (ACO) and, subsequently, as part of Option#4 presented in the CAAA Report and approved by DEP in April ' 2005. Now that site investigation activities have been substantially completed and the transfer station design is 70+/-% complete, we have been able to develop more accurate estimates of probable construction costs. Consequently, we have been able to prepare an attractive financial ' package to the City. The cost proposal is included in Section C of this proposal (separately bound). ' 031607 Salem Transfer Station Page A-1 Excerpt from Northside Carting Proposal dated March 16, 2007 Compatibility with Neighborhood During initial design activities, care was taken to locate the transfer station as far from residential ' areas as possible and to orient the building to shield area residents from day-to-day activities. To that end, the main access doors to the proposed transfer station are located on the northwest side of the building. Since that portion of the site is nestled into the embankment, most of the ' trucking activity will be screened from view and noise impacts to the neighborhood would be minimized. A layout of the proposed transfer station is illustrated on Figure 1 in Appendix 1. The current site aesthetics would be greatly improved with the proposed development plan. Reference is made to a color rendering of the proposed transfer station presented on the cover of this proposal. The layout of the main access drive off Swampscott Road has been modified to allow for more streamlined access to and from the scale house. Currently, larger vehicles sometimes create ' traffic delays while they negotiate the tight turning radius into the site as they approach from the north. ' We have also held informal meetings with City officials and area residents and agreed to change the proposed color of the building to green, in an effort to blend the facility with the environment. We are committed to continue to work with area residents to finalize the layout, design and features of the transfer station to minimize any adverse impacts. Public Benefit Continued use of the site as transfer station provides for the following benefits to the public at large: ➢ Cleanup and capping of a blighted site. Reference is made to the front cover of this proposal for"before" and "after" views of the site; ➢ Readily available solid waste management facilities for local residents and businesses; ➢ Ongoing environmental monitoring for protection of human health and the environment; ➢ Community Drop-off Area for recyclable materials (paper, plastics, and glass) and ' yard wastes; and ➢ Lower tax rate, based upon the value of services offered to the City, as described in the following section.

OF PLANNING& Carey Duques, COMMUNITY DEVELOPMENT Salem Conservation Commission 120 Washington Street Salem, MA 01970 Dear Ms Duques: I am writing to the Commission in support of the proposal by North Side Carting top cap the landfill on Swampscott Road. I have followed this issue in the local media and feel that the time for action is long overdue. This proposal is environmentally sound and is allowing the City of Salem to avoid enormous financial costs. The Commonwealth has been very patient in waiting for action by the City and I feel we should allow this project to move forward. North Side Carting has done an excellent job in operating the Transfer Station since they began operations over 10 years ago. I recall how the facility was previously run and their operation is a great improvement. For these environmental and financial reasons, I strongly recommend the Commission's approval.

As an abutter and neighbor of Northside Carting, we appreciate the time and care the company has put into the design and landscaping of the facility, and support their proposal to clean the site at a cost of $2.8 million. These proposals, as well as the continued tax revenue and the creation of local job opportunities the transfer station project will generate, are all positive developments for the city of Salem We also note that Mayor Kimberly Driscoll and the Salem News have voiced their support of this project.

As a resident,taxpayer, and pro-active business owner in the city of Salem for over 25 years, I strongly support the proposal presented by NorthSide Carting. The Proposal is truly beneficial for both parties,as it erases the liability to the city and Promotes a strong and accountable in base for years to come. Legally and Plscally this makes sense. N.S.C. has demonstrated throughout the years to be an asset to the city, They have conducted a fair and professional business for many years while providing a valuable service to the nearby residents and businesses of Salem. My opinion is strongly supported by the fact that N.S.C. is located within 200 yards of my business.and,therefore,have spoken to many neighbors and surrounding businesses,finding widespread support, It is incumbent upon the city of Salem to reach an accord with N.S.C. and,finally get closure to an ongoing problem that could be economically crippling to the city, ids, c Gary . adeau 02/13/2008 16:59 9786863086 NORTHSIDE CARTING PAGE 01 Northside C=ing Inc.

As the former Salem City Solicitor, I was fully involved in the Transfer Station matter throughout my tenure with the City's Legal Department and ultimately negotiated a new lease for the Station,as well as a mandatory environmental clean-up at the site. As you know,the Department of Environmental Protection has ordered the City to clean up and cap the site,and has levied fines against the City for failure to do so. The proposed plan would relieve the City of clean up costs,mounting finks, and provide a much needed revenue source. Again,I am pleased to offer my full support for the plan submitted by the City of Salem and Northside Carting, Inc. Thank you for your thoughtful consideration. Very truly yours ohn D.

During this timeframe,the City of Salem has been ordered to clean-up this property or risk the assessment of fines from the Department of Environmental Protection (DEP)that could equal as much as $25,000 daily for noncompliance. According to a recent estimate prepared by BETA Group Inc. the cost for closure and monitoring of the Salem landfill, in essence the clean-up costs, assuming the Transfer Station is not built on the site, is $2.85 million. As you can imagine,the City does not have the funds to pay for clean-up of the site or to cover the potential DEP fines. In addition,the City's Planning Department has been quite aggressive in seeking out grant funding to assist with the environmental clean-up costs to no avail. Northside Carting,the operator of the Salem Transfer Station, had a lease with the City that expired on June 30, 2007. In February of this year,the City issued a Request for Proposals (RFP) seeking redevelopment proposals,either through purchase or long-term lease, for the site including, but not limited to,proposals for its continued use as a transfer station. This site contains approximately 9.2 acres of property of which only 3.8 acres is buildable. The property is located in BPD Zoning District. As part of the RFP,the selected bidder will be responsible for all clean-up costs and were required to submit a plan for site mitigation that complies with DEP regulations. The RFP was aggressively marketed to area developers especially those interested in office or commercial development. Not only did the City market and promote this property to potential developers but we also highlighted the City's willingness to provide financial incentives to assist with purchase of the property including Tax Increment Financing (TIF), District Improvement Financing(DIF) and the City's Small Business Loan Program. Also,the competitive financial programs offered through MassDevelopment were highlighted. While many prospective developers reviewed the RFP and despite our best efforts the City only received two bid responses—both for the continued operation of a transfer station. Northside Carting,the current operator,was selected as most advantageous as per the RFP and City officials are in discussions to finalize purchase terms. As it looks,the City stands to flip an Salem City Hall—93 Washington Street—Salem, MA 01970-3592 Ph.978-745-9595 Fax 978-7449327 approximate $2.85 liability, along with potential daily fines from DEP, into a productive property generating approximately$200,000 annually in property taxes and host fees. The deal would also ensure the appropriate clean-up of a major brownfield site in the City. Due to the high clean-up costs associated with the property,both bids received by the City included an increase in daily tonnage allowed at the Transfer Station. Northside Carting's bid included the smaller increase of the two which is one of the main reasons they were selected. In addition,Northside Carting maintains services for residents,including yard waste and limited household trash drop-off. Lastly,the City's Transfer Station Committee successfully negotiated mitigation language related to the increase in tonnage and its anticipated impact on traffic and air quality. Further limitations on tonnage were agreed to by restricting Northside Carting from exceeding 25%of the daily tonnage,or 500 tons,to make up any shortfalls that may have been incurred in a prior period. With regard to traffic concerns,Northside Carting estimated that an additional 300 tons per day may result in 25 more trucks,or 50 more truck trips,per day. 50%or more of these trucks is estimated to be Northside Carting vehicles. Due to the size of the current vehicles that utilizes the transfer station(cars,pickups and small dump),there may be a reduction in the number of those vehicles from 25-35 per day to that of 15-20 per day. Lastly, Northside Carting has agreed to mitigate impacts to air quality by planting additional trees, purchasing alternative low-sulfur fuel for their waste handling vehicles,retrofitting all yard vehicles and up to ten collection vehicles that service the Salem area with diesel reduction filters and stricter enforcement of the idling policy imposed by the state. Given the current situation, especially the City's fiscal exposure with regard to this facility,I think we are proceeding in a reasonable manner and urge the Conservation Commission to approve the Notice of Intent for this project.

I have not heard from Kevin yet regarding rescheduling the site visit but will be in touch as soon as I hear. i Questions/concerns: - How will the material exposed during the process of day-lighting the river be handled? Will it be capped? - The new plans should reflect the removal of the 60 feet of culverted river - Concerns about the width of the roadway leading to the rear of the site, proposed drop-off area for residents, can it accommodate two cars? - Requested detail of guardrails to be located along roadway leading to the rear of the site - Requested profile showing layers that make up the cap - Concerns about existing catch basin(s)on site and procedure to discontinue it/them - Question about location of proposed guardrails throughout entire site, retaining walls are noted but not guardrails - Question about lack of curbs; you explained how cape cod berms will be used but the question was raised about how they will hold up to the plows during winter; what is outlined in the O&M plan? - Question about Phase 11 Comprehensive Site Assessment, mentioned that you could bring a mp to the next meeting showing the location of the test pits. - Questions raised about section of property that is outside of the property line - Questions about final restoration plans, details about plantings, what and how restoration would occur along river bank and other sections of the site. I hope this helps. Please feel free to call or email me with questions. Also if you decide to continue please let me know as soon as possible.
