A brief history of this project is provided below: • A Notice of Intent(NOI) was filed in September 1997 to perform the following: o Raze buildings; o Convert the area formerly occupied by the buildings to a parking lot with landscaped island; o Improve stormwater management; o Resurface Colonial Rd and parking areas; and o Add plantings. • An OOC was issued to Univar in November 1997; • In 1998, work completed on the property included: o Removal of buildings B, C and D; o Paving of a portion of the area previously occupied by buildings; I 05 October 2015 Environmental Page 2 Resources i Management o Constructing a landscaped island where Buildings B and C stood; o Installing a granite curb along sections of the perimeter of the property; and o Modifying the stormwater drainage system. Univar and other personnel who prepared the Notice of Intent are no longer available; therefore, ERM peformed the following tasks: • Conducted a file review at the Salem Conservation Commission on 29 September 2015 to review the NOI, OOC, and project notes included in the project file; • Compared the drainage system configuration proposed in the NOI and referenced in the OOC with the current configuration of the storm water system; and • Reviewed available project documentation. Based on these evaluations, it is clear that buildings B, C and D have been removed and a vegetated island has been installed. The former locations of buildings B, C and D and the current location of the vegetated island and adjacent paved areas are shown in Figure 2. The existing stormwater drainage system, with rim elevations at each catch basin, is shown on Figure 3. Granite curbing was installed at the edge of the parking lot, adjacent to Mill Pond. The removal of buildings and installation of a vegetated parking lot island, and the current configuration of the stormwater drainage system are generally consistent with proposed drainage plans referenced in the OOC. In addition to Form 8A, ERM respectfully submits the attached partially completed WPA Form 8B for your convenience and use should the Commission grant a Certificate of Compliance for this project. 05 October 2015 Environmental Page 3 Resources Management Please do not hesitate to contact me at 617-823-1065 if you have any questions regarding this submittal.

Portions of the proposed activities will occur within previously altered Riverfront Area and the Buffer Zone to Bordering Vegetated Wetland(BVW). ' LEC Environmental Consultants,Inc.(LEC)conducted field investigations on March 28, 1997 to identify and characterize existing wetland resource areas protectable under the Massachusetts Wetlands Protection ' Act(M.G.L.c. 131,s.40),its Regulations(3 10 CMR 10.00),the Rivers Protection Act(St. 1996,c.258), and the Salem Wetlands Protection Ordinance. Based upon the existing site conditions this NOI Application has been submit for Redevelopment Within Previously Developed Riverfront Area in ' accordance with 310 CMR 10.58(5). The floristic,edaphic,and surficial hydrologic attributes of the wetland resource areas have been utilized in the preparation of this Notice oflntent Application and Wetland Resource Area Analysis. This report also describes proposed activities and mitigating measures intended to minimize potential impacts to wetland resource areas and improvements to existing site conditions. Details ' of the proposed activities and mitigating measures are shown on the accompanying Site Plan prepared by Meridian Engineering,Inc.(MEI)and Planting and Dimension Plan prepared by Osbome Architects (Appendix Q. 2. Wetland Boundary Determination Methodology LEC conducted site evaluations on March 28, 1997 to identify and characterize wetland resource areas located on or adjacent to the site. The extent of BV W was determined through observations of the existing plant communities and hydrologic indicators in accordance with 310 CMR 10.55(2). Specifically,soil characteristics and vegetative densities were analyzed in accordance with Delineating Bordering Vegetated Wetlands under the Massachusetts Wetlands Protection Act,A Handbook (March 1995). Riverfront Area ' was determined according to 10.58(2)(a)3 which states that Riverfront Area is the area of land between o river's mean annual high-water line measured horizontally outward from the river and a parallel line located 200 feet away...and section 10.58(2)(a)2 which states that The mean high tide line serves as the ' mean annual high water line for tidal rivers. ' 2.1 Measurement of Floristic Characteristics 2.1.1 Plant Species Identification LEC identified plant species comprising 5%or more of the vegetative cover in the existing BV W. Identifications were made to the species level when morphologically possible and were used to define the boundary of BV W in accordance with definitions and criteria in 310 CMR 10.00. A summary of findings ' can be found in Tabular Form in Appendix B. ' Page I of 9 Noticc of Intent Application Van Waters&Rogers Colonial Road,Salem,MA - ' 2.1.2 Identification of Wetland Indicator Species The regional wetland indicator status of all identified plant species was obtained from the classification ' - system described in the National List of Plant Species that Occur in Wetlands:Massachusetts(Reed, 1988). This classification system divides plant species into six categories(`wetland indicator status")based on the frequency of their occurrence in wetland habitat and has been adopted by the Department of Environmental ' Protection(DEP)as the definitive source regarding the indicator status of wetland plants. - 2.1.3 Measurement of Relative Abundance ' The relative abundance of each plant species occurring in each wetland resource area was determined visually and ranked according to the following classification system:"++"=occasional or rare,"+"=less than 5%,"1"=5%- 10%, "2"=10%-25%, "3"=25%-50%,"4"=50%-75%,and "5"=75%- 100%. ' This methodology was obtained from Mueller-Dombois and Ellenberg(1974). 2.1.4 Measurement of Vegetative Distribution ' The relative pattern of plant distribution was determined visually and ranked according to the following classification system:"1"=single plants,"2"=groups,clumps,or clusters,"3"=small patches of large groups,"4"=large patches or broken mats,and"5"=nearly complete,extensive mats. This methodology ' was obtained from Mueller-Dombois and Ellenberg(1974). In addition,this classification system represents a modification of the methodology utilized under DEP policy guidelines for wildlife habitat evaluations(Wetlands Program Policy 88-1 and Wetlands Wildlife Advisory#2, 1988). 3. General Site Description ' The site encompasses approximately 11.7 acres located east of Jefferson Avenue in an industrialized area of Salem,Massachusetts. The site is bounded to the east,southeast,and northeast by the Boston and Maine railroad right-of-way while the southern portion of the site is bound by residential and commercial/industrial ' development. A tidal steam,associated tidal flats,persistent emergent marsh,and overhead utility wires are located north and northwest of the site. Topography gently slopes westerly with a steep rock outcrop occurring in the extreme southern portion of the site. The site is dominated by industrial development ' characterized by warehouse and distribution of packaged and bulk food additives and chemicals,office space,and parking lots. ' Existing vegetation present on the site is limited to a narrow bands of upland including red maple(Acer rubrum)and black locust(Robinia pseudo-acacia)saplings,staghorn sumac(Rhus typhina),Japanese knotweed(Polygonum cuspidatum),common reed(Phragmites australis),purple loosestrife(Lythmm ' salicaria),goldenrods(Solidago sp.),and grasses(family Poaceae sp.). 3.1 State Listed Endangered Wetlands Wildlife Species According to the Ipswich quadrangle of the Massachusetts Natural Heritage and Endangered Species ' Program Atlas of Estimated Habitat ofState-listed Rare Wetlands Wildlife,no areas of rare or endangered wetlands wildlife exists on the site(Appendix A,Figure 3). ' 3.2 Floodplain Designation Based on the 1985 Federal Emergency Management Agency Flood Insurance Rate Map for the City of Salem,Massachusetts,(Community Panel No.250102 005 B)the site is located within,Zone C: Areas of ' minimal flooding and Zone B: Areas between limits of the 100-year flood and 500 year flood;or certain Page 2 of 9 Notice of Intent Application Van Waters&Rogers Colonial Road,Salem,MA ' areas subject to 100 year flooding with average depths less than one(])foot or where the contributing drainage area is less than one square mile;or areas protected by levees from the base flood. ' 4. Wetland Resource Areas ' Pursuant to the Massachusetts Wetlands Protection Act(M.G.L.c. 131,s.40),its Regulations(3 10 CMR 10.00),the Rivers Protection Act(St. 1996,c.258),and the Salem Wetlands Protection Ordinance the tidal stream,associated tidal flats,and persistent emergent marsh located on or adjacent to the site include the t following wetland resource areas: Tidal Stream,Tidal Flats,Bordering Vegetated Wetland(BVW),and Riverfront Area. A tidal stream,associated tidal flats and persistent emergent marsh are located in the northeastern,northern, ' and northwestern portions of the site. The stream is characterized by a well defined,meandering channel approximately five feet wide and two to three(2-3)feet deep with a mud streambed. The aforementioned tidal flats are 15-35 feet wide. Approximately 6-24 inches of slowly,westerly flowing water was ' observed within the channel and across the tidal flats at the time of the evaluation. During the incoming tide the stream inflows the site from the east through two five foot square,granite culverts located beneath the aforementioned railroad right-of-way and outflows the site to the west/southwest through four,four foot ' diameter culverts located beneath Jefferson Avenue. Topography within the aforementioned marsh is flat. A steep,northerly sloping embankment of fill material(road debris,tires,concrete slabs,etc.)abuts the southern boundary of the marsh. Two twelve inch storm drains discharge into the marsh from parking lots and storage areas located to the south. Vegetation within the marsh is dominated by a dense,continuous stand of common reed(Phragmites communis). The wetland/upland boundary is demarcated with flagging stations LECI through LEC52. III ' Riverfront Area extends 200 feet southeasterly from mean high water(elevation 4.92). The majority of the Riverfront Area is characterized by warehouse,office space,and parking lots. Vegetation within the Riverfront Area consists of a narrow band adjacent to the BV W. This narrow band of vegetation is ' dominated by invasive and/or exotic species including red maple(Acer rubrum)and black locust(Robinia pseudo-acacia)saplings,staghom sumac(Rhus typhina), and Japanese knotweed(Polygonum cuspidatum) in the shrub layer and common reed(Phragmites australis),purple loosestrife(Lythrum salicaria), ' goldenrods(Solidago sp.),and grasses(family Poaceae sp.)in the ground cover. 5. Proposed Activities The Applicants propose to raze portions of an existing industrial building,convert the area to a parking lot ' with landscape islands,improve stormwater management,resurface Colonial Road and the existing parking lot,and add enhancement plantings. Portions of the proposed activities will occur within previously altered Riverfront Area and the Buffer Zone to Bordering Vegetated Wetland(BV W). ' The existing warehouse encompasses approximately 149,840 square feet. A portion of this warehouse (65,840 s.f.)will be razed and converted to office space,parking and loading areas and landscape islands. Approximately 3,350 s.f of this conversion will occur within Riverfront Area. In addition,portions of the Page 3 of 9 ' Notice of Intent Application Van Waters&Rogers Colonial Road,Salem,MA i ' existing parking area located adjacent to the BV W will be reconfigured,eliminating approximately 1 I parking spaces. This reconfiguration will reduce the square footage of parking area located within ' Riverfront Area and the Buffer Zone to BV W by approximately 3,600 square feet.This area will be landscaped with enhancement plantings as described in section 6,Mitigation Measures. As outlined in the Stormwater Analysis and Calculations prepared by MEI(Appendix B),this reconfiguration has resulted in tan overall reduction in impervious area for the site when comparing the existing and proposed condition. ' 6. Mitigation Measures The Applicants propose to implement the following mitigation measures to minimize site disturbance, ' improve existing conditions,and conform with the pertinent performance standards. 6.1 Stormwater Management ' Under current conditions stormwater from the site is directly discharged via surface sheet flow and a culvert that discharges stonni lows into the BV W resulting in periodic impacts to water quality during storm events. The Applicants propose to improve this condition by installing a curb between the parking area and BV W ' and directing all storm flows from the parking area into the storm drainage system. Four existing catch basins located with the upper drainage area will be replaced and two new catch basins will be installed,each equipped with four foot sumps and oil/grease traps to capture and retain particulates In addition,several ' drain lines will be upgraded with new larger pipes,and new lawn landscape areas will be created. As proposed,this system will result in a net improvement to the water quality of storm water runoff. For additional detail see Stormwater Analysis and Calculations prepared by MEI(Appendix B). ' 6.2 Enhancement Plantings The Applicants propose to establish a landscaped enhancement plantings in the parking area islands. Additionally,a vegetative buffer strip of enhancement plantings is proposed along the northern perimeter of the site between the limit of the parking area and the adjacent BV W. These enhancement plantings are intended to improve wildlife habitat within Riverfront Area,and provide a vegetative screen to limit access to the wetland resource(s),thereby deterring unauthorized encroachment or alteration of the wetland. ' During installation of the vegetative buffer,invasive and or exotic species currently growing within the area will be selectively removed. The vegetative buffer and parking area island will be planted with a variety of deciduous,evergreen,and flowering trees and shrubs to provide a cover and food source for wildlife. 6.3 Erosion and Sediment Control The Applicants propose to implement an erosion control program to protect adjacent wetland resource areas ' from sedimentation during the proposed activities. The plan for the control of potential impacts to these . resource areas is based in part on guidelines contained in the Field Guide for Low-Maintenance Vegetation Establishment and Management(Environmental Laboratory, 1986)and BPM's contained within the ' Megamanual(Massachusetts Nonpoint source Management Manual)published by the DEP Office of Watershed Management. Siltation barriers composed of double-staked hay bales and a fabric filter fence will be installed. All barriers will remain in place until the proposed vegetative buffer and disturbed areas ' are stabilized by vegetation. Locations and details of the existing and proposed siltation barriers are shown on the site plan prepared by MEI(see Appendix C). ' Page 4 of 9 Notice of Intent Application Van Waters&Rogers - Colonial Road Salem,MA ' 7. Summary The Applicants,Van Waters&Rogers,Inc.and Exeter International Realty Corporation,propose to raze portions of an existing industrial building,convert the area to a parking lot,improve stormwater ' management,and resurface Colonial Road and the existing parking lot with landscape islands within previously altered Riverfront Area and the Buffer Zone to Bordering Vegetated Wetland(BVW). The Applicants propose to implement an erosion control program to serve as the limit of work,thereby ' minimizing disturbance and proposes to improve the existing stormwater management system to improve water quality prior to discharge. Finally the Applicants have proposed to enhance the Riverfront Area by establishing landscaped enhancement plantings in the parking area islands and a landscape buffer between ' the parking lot and BV W to improve wildlife habitat and provide a vegetative screen to limit access to the resource area and deter unauthorized encroachment or alteration of the BV W. The proposed mitigating measures conform with the performance standard enumerated in the Massachusetts Wetlands Protection Act ' (M.G.L.c. 131,s.40),its Regulations(3 10 CMR 10.00),the Rivers Protection Act(St. 1996,c.258),Final Regulatory Revisions to the Rivers Protection Act Amendments to the Massachusetts Wetlands Protection Act(Effective October 6, 1997), and the Salem Wetlands Protection Ordinance,and represent an overall ' enhancement to water quality and wetland functional values of the site. t. 1 tPage 5 of 9 Literature Cited ' Boutiette,Jr.,L.N.and C.L.Duerring. 1994.Massachusetts Nonpoint Source Management Manual, "The Megamanual"A Guidance for Municipal Officials.

As you recall, the Company is in the process of a major site upgrade which includes extensive work to the existing warehouse, installation of a new tank farm, and demolition of two old buildings (buildings marked C & D on the plans filed with the Order of Conditions) . In the course of construction the Company has determined that it is advisable to take down two more old buildings on the site consisting of the old laboratory and a storage building. These buildings are marked "laboratory" and "chemical storage building H" on the attached sketch plan and correspond to buildings B and F on the original plans filed with the above Order of Conditions. The proposal is to remove the buildings B and F to their slabs. No underlying soil beneath the slabs will be disturbed. In the case of each building, a portion of it lies within the two hundred foot buffer zone as shown on the original plans, which results from the application of the Rivers Act. Steven Dibble, Coordinator Conservation Commission August 27, 1998 Page Two. The applicant submits that there would be no impact from the additional demolition on either the resource areas or the buffer zones and requests that the Commission issue an amendment to the above Order approving the additional demolitions at its earliest convenience. A Company representative will plan to attend the next meeting on September 10, 1998 and will be available to answer any questions. Thank you for your cooperation. Very truly yours, hn R.

Determine the capacity and effectiveness of the existing stormwater systems. ii. Determine mitigative measures that can be implemented to promote stormwater ' quality. ' SELECTION OF STORM EVENTS The storm events have been compiled from the Soil Conservation Service Technical ' Report No. 55 and the U.S. Department of Commerce Technical Paper No. 40. The rainfall frequency data has been provided as follows: ' Frequency (Years) Rainfall (24 hour event finches)) ' 2 3.1 10 4.5 100 6.5 1 OVERVIEW- EXISTING SITE CONDITIONS In the existing condition,the site is used as an industrial lot and is approximately 12.5 acres in size. Multiple buildings are located on site. The remainder of the site is ' predominantly a paved area and is completely developed. The site is divided into an upper and lower area and contains five (5)major catchment areas. These areas are shown on the pre-development drainage plan as A through E. The upper area is comprised of catchment A, B and C and the lower area catchments D and E. Each area contains its own separate stormwater system. ' In the upper area, catchment A, discharges through a 12"pipe to the west of the site near wetlands along Mill Pond, a tidal water body. Catchment B flows overland to Mill Pond. ' Catchment C flows overland off site. In the lower area, catchment D discharges through a containment house to Mill Pond on ' the north side of the site. Catchment E flows overland to Mill Pond. The existing site is completely developed with a significant portion of the site being paved areas and buildings leaving only a very small area of open space. The work on this site is to be ' considered a redevelopment project as per the Massachusetts DEP Stormwater Management Guidelines. 1 SOIL CONDITIONS ' Soil conditions have been established by Soil Survey of Essex County (SCS). Slopes at the site range from flat near Mill Pond across the site to a steep slope at the edge of the ' site along the southern property line. On site soils conditions have been classified as Urban Lands, which lie in Group D, by the USDA, Soil Conservation Service. EXISTING STORMWATER SYSTEM Upper Area (Catchments A, B & C) I ' The drainage study performed on the upper area, catchments A and B concentrates on the stormwater runoff flowing to what is shown as Design Point AB on the subcatchment ' plan. There are two separate catchment areas A and B discharging to this point. Catchment C discharges overland to the railroad tracks to the east side of the lot. Catchment A, approximately 2.78 acres in size,consists of a portion of the existing warehouse roof and parking areas which are collected and discharged to Design Point AB through the existing upper area stormwater system. Catchment A contains many ' subcatchment areas collecting stormwater through various catchbasins. ' Catchment B, approximately 1.62 acres in size,consists of overland flow to Design Point AB from the area west of the warehouse along Colonial Road and contains a portion of the warehouse roof,parking and landscaped areas. A large portion of the existing roof ' directly discharges to the parking area and flows overland to Design Point AB. Catchment C, approximately 3.69 acres, consists of the open space to the south of the warehouse,parking areas to the east of the warehouse and a portion of the warehouse roof. A large portion of the existing roof directly discharges to the parking area and flows overland to Design Point C. The existing stormwater system servicing catchment A consists of a series of interconnected catchbasins connected in series discharging to wetlands located to the ' west side of the site. The subcatchment area draining to this stormwater system consists of approximately one third of the upper area. This system of catchbasins and ' interconnecting pipes were evaluated to determine its capacity and effectiveness at conveying stormwater and removing pollutants. 1 Below is a summary of the catchment areas located on the upper area. ' Peak Flow(cfs) Catchment 2 Year 10 Year 100 Year ' Aand B 6.4 8.3 10.9 ' C 7.2 11.7 18.1 ' Volume (acre-feet) Catchment 2 Year 10 Year 100 Year ' A and B 0.84 1.25 1.82 C 0.55 0.90 1.40 The carrying capacity of the existing drainage pipes in the series is undersized to convey the two (2) year storm event which will peak at more than 7 cfs. Observations in the field ' indicate that localized ponding occurs over the catchbasins as well as runoff flowing overland to the wetlands near Design Point A.B. The calculations indicate that stormwater bypasses the collection system thus "treatment' of stormwater is not being ' performed efficiently. ' Lower Area (Catchments D & E) ' The lower area contains two catchment areas, D and E. The drainage study done on the lower lot analyzes the existing stormwater collection system draining to the containment house, catchment D. This system outlets into the Mill Pond at Design Point DE. Catchment D, 3.42 acres in size, consists of Buildings A through F, and H, with a portion of G and paved parking and loading areas. The roof discharge directly to the paved ' surfaces and flow overland to the catchbasins. Catchment D contains 100% impervious surface areas. ' Catchment E consists of a portion of the roof to Building G and open space to the north of building G. This catchment flows overland to the Mill Pond. The stormwater collection system servicing Catchment D consists of interconnected catchbasins in series discharging to the containment house. This catchment contains the majority of the lower lot. The study of this collection system was made with the assumption that all of the gates located on this drainage system are in a fully opened position. The gates being in any other point of operation would seriously skew the results ' of this study. Below is a summary of the catchment areas located in the lower area. I ' Peak Flow(cfs) Catchment 2 Year 10 Year 100 Year D and E 4.5 5.5 7.0 Volume(AF) ' Catchment 2 Year 10 Year 100 Year D and E 0.79 1.17 1.57 PROPOSED STORMWATER SYSTEM The proposed construction on site is limited to the upper area, leaving the lower area ' virtually undisturbed. Therefore,the upper drainage system will be limited to this area. The stormwater management system has been upgraded in three ways: new catch basins ' with 4 foot sumps and oil/grease traps will be added, several drain lines will be upgraded with new larger pipes, and new lawn/landscaped areas will be added. ' The existing catch basin CB 1 will be replaced with a new catch basin PCB 1 (with 4 foot sump and oil/grease trap) and placed in line from CB2 to the outfall. This will provide treatment for all stromwater entering the upper area drain lines, as all of the upper drain ' lines will pass through PCB 1 before discharging to the outfall near design point A.B. A new catch basin(PCB2)will be added in the new parking area adjacent to the new office area of the warehouse. PCB2 also has a 4' sump and an oil\grease trap to provide ' 25%TSS removal. PCB2 will be connected to PCB1 via a 12"CLDI pipe. Three existing pipes will be replaced with new larger and smoother pipes that will ' increase flow within the reach. The 12"RCP drain line from CB3 to CB2 will be replaced by an 18" CLDI pipe. The 12" CMP pipe from CB2 to the outfall will be ' replaced by an 18" CLDI pipe running from CB2 to PCB 1 and then to the outfall. All inverts will remain as is. The larger pipe diameter will promote an increase in flow through the stormwater system,thus allowing a larger volume of water to be treated tbefore being released into the wetlands near design point AB. Two new grassed areas will be added near the new office area and adjacent to the existing building B. The area of new grassed/landscaped area is 0.45 acres. The new grassed area Mill directly treat stormwater by the processes of sedimentation, filtration and infiltration. ' Below is a summary of the flow and volumes for the proposed conditions. Peak Flow(cfs) Catchment 2 Year 10 Year 100 Year ' A and B 10.3 14.2 14.3 C 7.4 11.8 17.9 D and E 4.5 5.5 7.0 Volume (acre-feet) ' Catchmen 2 Year 10 Ye 100 Year A and B 0.81 1.21 1.78 C 0.57 0.91 1.38 D and E 0.77 1.17 1.56 POLLUTANT "FIRST FLUSH" REMOVAL The Massachusetts Department of Environmental Protection, (DEP) Stormwater Management Guidelines measure the amount of pollutant removal by the removal of total suspended solids, TSS, from the stormwater runoff. This removal is based on generally ' accepted methods as outlined in the Massachusetts DEP Stormwater Management Guidelines. Pollutant removal is now considered by the DEP to be as critical a measurement of the effectiveness of a drainage system at its carrying capacity. ' Due to the age and method of construction of the existing stormwater system, the system provides no pollutant removal. The existing catchbasins contain no sumps. Catchbasins ' with sumps are given a TSS removal rate of 25%. The existing drain lines are undersized which leads to ponding over the catchbasins. This ponding allows stormwater to drain ' directly into the wetlands without receiving any treatment. To promote treatment two (2) catchbasins (PCB1 and PCB2) with 4' sumps and ' oil/grease traps will be added to the drainage system and three (3) existing drain lines will be upgraded with new larger diameter pipes. The new catch basins with sumps and oil/grease traps will provide a TSS of 25%. The new drain lines will decrease ponding over the catch basins causing more stormwater to go through the system and receive treatment. 1 Conformance to the groundwater recharge criteria for the site would not be required due to the classification of the on site soils as Group D soils by the Soil Conservation Service. 1 SUMMARY OF PEAK FLOWS AND VOLUMES ' Design Point AB (Reach 1) ' Storm Event Existing Conditions Proposed Conditions ' 2 Year(3.1 in.) 6.4 cfs/0.84 AF 10.3 cfs/0.81 AF. 10 Year(4.5 in.) 8.3 cfs/1.25 AF 14.2 cfs/1.21 AF.

For design points C and DE the flows also change very little. The flows for design point AB do increase in the proposed condition as the new pipes with larger diameter allow more stormwater to ' enter the stormwater drainage system thus reducing ponding over the catch basins. Although the total flow discharging to design point AB will increase in the proposed conditions, the amount of treatment that the stormwater receives is much greater than in the existing conditions. CONCLUSION ' The existing on-site stormwater system is deficient in both its capacity and treatment of stormwater. The upper drainage basin, which comprises of catchments A and B, by calculation is not able to handle the two year storm event. During heavy storm events water bypasses the collection system and discharges overland into Mill Pond. The bypassing of the collection system causes stormwater to enter the resource area "untreated". The existing catchbasins do not have sumps nor traps to collect sediment. The lack of sumps and traps allows sediment to freely flow into the collection system which in accordance with the DEP Stonnwater Management Standards does not provide ' an effective nor efficient system to remove potential pollutants. The proposed revisions to the stormwater collection system,within the upper drainage ' area, will include the replacement of the existing catchbasins with new structures which contain four foot sumps and oil/grease traps. The sumps will allow sediment to settle to the bottom of the sump prior to being discharged into the piped system. The oil/grease ' traps will contain potential pollutants within the catchbasin and not allow the discharge of these potential pollutants into the piped system. The pipes within the upper drainage system have been re-designed to handle a five year storm event. The larger pipes will allow a greater storm event to be contained within the collection system, thereby, not allowing water to discharge overland during the smaller and more frequent storm events. The proposed work also will provide approximately one-half (0.5) an acre of new lawn/landscaped areas which will assist in the process of sedimentation removal and will provide some exfiltration into the ground. The combination of the new catchbasin structures with sumps and traps, the larger pipes within the upper drainage area and the newly created lawn/landscaped areas will provide an improved stormwater system that promotes water quality to a site that is currently developed. fAxinword\npoM\3018dc2 1 1 1 ' EXISTING CONDITIONS ROUTING DIAGRAM 1 Data for 3018 Van Waters & Rogers (exist. conditions) TYPE III 24-HOUR RAINFALL= 3 .1 IN fHrepared by MERIDIAN ENGINEERING, INC. 5 Sep 97 vdroCAD 4 .00 000428 (c) 1986-1995 Applied Microcomputer Systems 'WATERSHED ROUTING 1 O O 111 ' s �z ie O_)F3 II� us Ifi ' lax ❑1 2 lis a 1 I01 100 yll ❑ 100 OSUBCATCHMENT REACH QPDND LINK 'SUBCATCHMENT 100 = Catchment B (overland to D.P.

The Department of Environmental Protection (DEP) recommends that ' applicants submit this form with the Notice of Intent, as well as supporting documentation and plans, to provide stormwater information for conservation commission review. If a particular stormwater management standard cannot be met, information should be provided to demonstrate how adequate water quality and water quantity ' protection will be provided by the project. DEP encourages engineers to use this form to certify that the project meets the stormwater management standards as well as acceptable engineering standards. This form should be completed by checking the appropriate boxes for each standard and by signing and stamping the back of this form- ' Project Location: 0 Colonial Road, Salem, Massachusetts ' ❑ The proposed project is/ it(circle one)exempt from one or more of the stormwater management standards. If project is exempt, explain why: The site is an existing developed site which has buildings ' and impervious areas covering approxima e y o 0 Stormwater runoff volumes to be treated for water quality are based on the following calculations: ' (check one that applies) ❑ 1 inch of runoff x total impervious area of post-development site for critical areas (e.g.,Outstanding Resource Waters and shellfish growing areas) ' ❑ 0.5 inches of runoff x total impervious area of post-development site for other resource areas Standard#1: Untreated stormwater (See plan (See attached Supplement) ' ® The project is designed so that new stornawater conveyances (outfalls/discharges)do not discharge untreated stormwater into, or cause erosion to, wetlands or waters. ' Standard#2: Post-development peak discharge rates (See plan_� (See attached Supplement) ❑ Post-development peak discharge rates do not exceed pre-development rates on the site either at the point of discharge or downeoradient property boundary. ® NIA:project site contains waters subject to tidal action,so standard is not applicable. ❑ Stormwater controls have been designed for the 2-year and 10-year,24-hour storms. ' ❑ The project's stormwater design will not increase flooding impacts offsite from the 100-year,24-hour storm. ' Standard#3: Recharge to groundwater (See plan (See attached Supplement) ® The annual groundwater recharge for the post-development site approximates annual recharge from existing site conditions. ' ❑ Soil types have been identified according to either the U.S.Natural Resources Conservation Service(NRCS) County Soils Survey or onsite soil evaluation. Calculations on stormwater flow are based on a soil hydrologic group of .and total impervious area of (square feet). ❑ Soil types at each planned point of stormwater runoff infiltratign include: ❑ Infiltration Best Management Practices (BMPs) used for this project include: ' Standard#4: 80% TSS removal (See plan (See attached Supplement) ' 11 The proposed Stormwater management systems will remove 80%of the post-development site's average annual load of Total Suspended Solids (TSS). ® The BMPs selected for this project include (list BMPs with TSS removal rates): t Catchbasins with deep sumps and oil/grease traps within the catchbasins. None of the existing catchbasins have sumps nor oil/grease traps. 1-10 stormwater Management (Volume One) 1 ' SUPPLEMENT TO THE STORMWATER MANAGEMENT FORM ' Standard#1: The proposed work consists of replacing the existing catchbasins, within the upper drainage area,with new structures that have four(4') foot sumps and oil/grease traps,re-designing the pipe system with larger pipes to convey additional stormwater, ' construction of lawn/landscaped islands and the installation of curbing adjacent to the resource area. All of the above proposed work will assist in the improvement of stormwater quality. ' Standard#2: The peak discharge rates from pre to post conditions in the upper drainage area(Catchments A&B) increase due to the proposed larger pipes. The larger pipes ' have been designed contain stormwater within the collection system, thereby promoting stormwater quality. The flow of all stormwater from the site discharges into Mill Pond which is subject to tidal action, therefore the standard to reduce peak discharge rates from ' pre to post conditions is not applicable. Because of the proposed lawn/landscaped areas, the overall volume of runoff decreases from pre to post conditions. ' Standard#3: The annual discharge of groundwater from pre to post conditions is approximately the same. The post conditions may actually promote additional surface ' water to recharge into the ground due to the proposed lawn/landscaped areas. The soils are classified as Group D and any proposal to infiltrate stormwater into the ground would not be feasible. ' Standard#4: The existing site is a fully, completely developed site that has impervious coverage on approximately eighty-five (85%)percent of the site. The proposed work -� does include newly created lawn/landscaped areas,however given the location of the existing buildings and structures, a proposal to meet the eighty(80%)percent removal of total suspended solids (TSS) is not possible. The proposal includes the following best ' management practices. ' Description Design Removal Rate * Catchbasin with deep sumps and hooded pipe outlets 25% ' * Installation of larger pipes No Credit Given ** * Creation of newly lawn/landscaped areas No Credit Given ** * Installation of curbing adjacent to the resource area No Credit Given ** ' ** The Stormwater Management Standards issued by the Massachusetts Department of Environmental Protection does not address the total suspended ' solid removal rates for the above described activities. 1 1 ' 10.
