Duques, On behalf of my client A&H Auto Exchange, I have prepared this correspondence to respectfully request to withdraw without prejudice the application for the Truck Scale ramp Request for Determination of Applicability (RDA) at the February 22, 2007 Conservation Commission meeting . As you are aware the decision had been appealed by the abutters and the original intent of the separate filing was to construct the ramps before winter,therefore we have combined the Truck Scale work with the revised NOI filing of January 25, 2007. The runoff from the Truck Scale area will flow into the swale (#2) and into the detention pond for treatment. The road will be raised to prevent the runoff from flowing down the road or into the stream. Please call if you have any questions. Very truly yours, SP Engineering, Inc. 4A&H Auto Ex ge Inc.

What I require for the drainage alteration permit is informal. meaning there is no formal permit but they need to prepare a plan of the site showing existing conditions, proposed work, and a letter report describing the work with pre and post development run off. We require a reduction in post development run off and again the amount is a bit informal depending on the site. All this must be stamped by a registered professional engineer in Massachusetts.

David & Dana DiLisio are the Trustees of D & D Realty Trust which owns approximately three acres of land at the corner of Robinson Road and Swampscott Road in Salem. They operate a miniature golf course on the property. A stream and wetlands are located on the D & D property. The D & D property is generally . at a lower elevation than 15.Robinson Road and run-off from 15 Robinson Road travels onto their property, including a stream running through their property. 2. Carmine & Angelo Mongiello, as tenants in common, own approximately 7.8 acres of land at the corner of Robinson Road and Swampscott Road. They own residential rental properties and operate businesses on their property. The Mongiello property is generally at a lower elevation than 15 Robinson Road and run-off from 15 Robinson Road travels onto their property, including a stream and culvert running through their property. A part of their land is directly below the proposed work. Background The December 5, 2006 Salem Conservation Commission negative determination appealed from is attached hereto as Exhibit A. The Applicant seeks to build "temporary" ramps for a scale house within the buffer zone of an intermittent stream and wetlands. The scale house itself appears to have been constructed, or had substantial new work performed on it, within the buffer zone, without any filings with the Conservation Commission The overall site has a severe flooding and drainage problem. Photographs attached as. Exhibit B from earlier this year show drainage from the Applicants land over-running the banks of the intermittent stream and overwhelming the hay bales and siltation fence placed on Applicant's land as a temporary protection against erosion from drainage. The first two photos show substantial flooding within less than ten feet of an occupied residential dwelling. The persistent result of the existing conditions has been sediment, debris and floating scum in the stream and wetlands as a result of up-gradient erosion. The applicant's submittal with respect to the ramps relies on the clearly inadequate hay bales and siltation fence. The existing steep slopes and lack of natural vegetation on the applicant's site are exactly the type of circumstance DEP has recognized as increasing the potential for adverse impacts on resource areas. 310 C.M.R. § 10.53. The scale is intended to be used to weigh scrap metal which may be contaminated with pollutants. Applicant's site contains old salvage vehicles and waste oils and other pollutants, making run off and erosion from the site a more serious issue. The proposed ramps are, at points, as close as twenty feet from the intermittent stream. (See the unstamped plan submitted by Applicant attached hereto as Exhibit Q. The existing drainage is depositing silt and other refuse in the stream and nearby wetlands and threatening to block a culvert through which the stream passes. The ramps to the scale house are based on assumed grades, The grades have not yet been approved as part of the required drainage master plan and Applicant merely assumes that the grades will be approved during the NOI processing and review of the master plan. The applicant is under an existing order to submit a master plan addressing and correcting all the storm water drainage problems over the entire site. These corrections are supposed to alleviate problems the abutters are suffering presently from the drainage problems. To date no adequate set of drawings has been submitted and the hearing has been postponed four times times. The last inadequatemaster plan was submitted with the original NOI. There was no data or calculations presented to the Commission by the applicant showing the affect of the ramps construction regarding run off water and how it will affect existing flooding, the existing stream and the wetlands on the Mongiellos or the Dilisios properties. The scale house ramps will be new structures and will have a significant impact on the runoff and on the buffer zone and wetlands. Although categorized as "temporary" the type of construction proposed tends to be very long term if not permanent. This increase of the problem without a master plan solution of the storm water drainage problem is unacceptable to the abutters. 1111 plans of applicant. to date have not been prepared e by a registered land surveyor or engineer. The plans have been vague and incomplete. They do not show necessary and important topography and elevations and do not locate all resource areas. As noted above, there are residential properties on abutting land that are already being threatened by the applicants run off water from his site. These homes will be in even more danger if the scale house work is undertaken without the appropriate data, assessments and master plan. T1Se Applicanthas ahistory of failingto comply withiegulatory laws. (Exhibit . D). A site view of the existing scale showed significant new concrete work performed without any submittals. Given the severe existing problems at the site, the fact that the ramps as so close to the stream and will add to a significant drainage and erosion problem and that the Applicant is not reasonably responding to the required master plan, the Commission's negative determination is clearly erroneous. Basis for Anneal Negative act of additional run off into resource area and potential for flooding of gariv impact Mongiello and DiLisio properties- 1. The scale structure is within the 100' buffer zone of an inland bank and BVW. The proposed ramps are within twenty feet of an intermittent stream. The proposed work will alter a neighboring wetland. 2. The applicant did not present any plans or data to show that the construction of the ramps would not increase run off which presently is directed towards the resource area and the abutting (Mongiello and DiLisio) property. 3. The surface run off from the applicant's property carries with it silt, debris and potential contaminants into the resource area and the abutting property. Present efforts to prevent or limit the run off(placing of hay bales and a temporary silt fence) have not been successful. The appellants voiced their concerns at the public hearing and requested additional measures be taken to mitigate or prevent the run off from entering the resource area and spilling over onto their property. - The Commission declined to consider this request notwithstanding the known conditions and consequences of diverting the surface water run off: 4. The applicant has before the Commission a separate application / plan (DEP 464- 426) that has been delayed due to applicant's lack of detailed plans and follow up to the Commission's previous comments and requests. That applicatlon.was filed in July of 2006 and includes the area of the proposed temporary ramps. In delaying that application, the applicant has avoided addressing the immediate concerns of the Appellants. 5. In allowing the construction of the "temporary"ramps the Commission is permitting the applicant to implement work under the DEP filing (964-426) without regard to negative impact to the resource area and the abutting property and before the requirements of the master remediation plan are determined.. Relief Requested The appellate abutters request a superseding determination of the Salem Conservation Commission negative determination with a remand requiring that adequate plans and information be provided by the applicant, including elevations approved by the DEP as part of an approved remediation plan, and determining that a NOI for the work is required.

After observing a few vehicles and speaking with your grandson, it was determined that the material was unscrcencd loam that was being stockpiled and screened and ultimately returned to Swampscott where it originated. I was in touch with the D.F.P. to confirm that the operation was not in violation of the, orders previously issued. Over the phone, based on my description the D.E,P agreed there was no violation. However, as previously pointed out by this Department, expanding the use of your property beyond the Automobile Salvage Business violates Salem Zoning Ordinance. The additional use would require, as a minimum a Special errnit.

The truck scale would be used to weigh steel, white metal and other materials that are being recycled in bulk. The entire scale unit is located within the 100' buffer zone of an inland bank and BVW. The unit consists of five concrete pillars, which are in place, a suspended steel frame and steel plate cover,which are also in place.To complete the installation it is necessary to build an earthen ramp on each side of the scale for accessAnterlocked Jersey barriers would be placed along the ramp to prevent the fill from falling onto the driveway. The ramps on both sides will have curbing and guard rails. Some fill will be placed against the first and second barriers to pin the bottom . The R-bars will be coated steel and epoxy sealer will be used at the headwall base to retard corrosion. The final grading for fixture runoff control and BMP will change the contours and road elevations, eliminating the Jersey barriers. The top of the existing concrete pillars is at elevation 81.72 while the surrounding grade is 80-81.0. The top of scale is 3' higher than the concrete which means the ramp will require 4-5' of fill at the scale ends. To prevent fill from falling under the scale a concrete headwall 1' thick by 12' wide and 3' high would be constructed against the scale. The structure would be formed on existing grade and pinned to the pillars No excavation is required. The ramp would be 60' long by 10' wide and slope 10%on the Robinson Rd. side and 5%on the house side of the scale. The 10' section closest to the scale would be paved with asphalt underlain with 6" of 3/4" crushed stone. The remainder of the fill used for the ramp ( approx. 50 cubic yards for each side ) would be on-site material consisting of large rock (6"and under)mixed with 30-40% sand and gravel and 10% silt as is typical of the fill pile on the property. The material would be placed by an excavator and packed in with the bucket. A track mounted bulldozer would be used to level and compact the ramp. Crushed stone(3/4") and Lynnpac (approx. 40 cubic yards)would be brought to the site and spread on the ramps to stabilize the surface and prevent erosion. A row of hay bales and siltation fence are in place along the brook bank approx: 30-70' from the proposed ramps.This aspect of the facility upgrade has been prepared separately from the NOI because of the need to pour the concrete and pavement before the weather turns cold: The current drainage flow is split between the swale area beside the driveway,and the road itself.The road flow proceeds to the inter section of Robinson Rd. and then flows south into the brook at the property line.This plan proposes to restore the drainage ditch on the north side of the scale ramps to direct.runoff from the ledge (non-impacted) along the north side of the road and to fill the eroded area beside the brook 1-2' to redirect flow away from the brook. The drainage ditch would be extended along the north side of the road by removing 10-15' of ledge and creating a 2-3' wide ditch to carry the runoff approx. 100' to the turn-off downgradient of the brook. This will eliminate the direct discharge into the brook and the final BMP grading will capture all the runoff and direct it into a detention pond as proposed in the NOI application.

Track Scali Dear Mz.Duques, The property owner desires to rebuild the truck scale adjacent to the driveway from Robinson Rd.The truck scale would be used to weigh steel,white metal and other materials that are being recycled in bulk. The entire scale unit is located within the 100' buffer zone of an inland hank and BV W.The unit consists of five concrete pillars,which are in place,a suspended steel frame and steel plate cover,which are also in place.To complete the installation it is necessary to build an earthen ramp on each side of the scale for access.Jersey barriers would be placed along the ramp to prevent the fill f oni falling onto the driveway. The final grading for future runoff control and BMP will change the contours and road elevations,eliminating the Jersey barriers. The top of the existing concrete pillars is at elevation 81.72 while the surrounding grade is 80-81.0.The top of scale is 4' higher than the concrete which means the ramp will require 5-6'of fill at the scale ends.To prevent fill from falling under the scale a concrete headwall l' thick by 10' wide and 6' high would be constructed against the scale.The structure would be formed on existing grade and pinned to the pillars No excavation is required. The ramp would be 60' long by 10' wide and slope 0.10%on the Robinson Rd. side and 0.05%on the house side of the scale.The 10' section closest to the scale would be paved with asphalt underlain with 6"of '/4" crushed stoic. The remainder of the fill used for the ramp(approx. 50 cubic yards for cub side)would be on-site material consisting of large rock(6"and under)mixed with 30400/9 sand and gravel and 10%silt as is typical of the fill pile on the property. The material would be placed by an excavator and packed in with the bucket.A track mounted bulldozer would be used to level and compact the ramp. Crushed stone(3/4")and Lynnpac (approx.40 cubic yards)would be brought to the site and spread on the ramps to stabilize the surface and prevent erosion.A row of bay bales and siltation fence are in place along the brook bank approx. 5070' from the proposed ramps.This aspect of the facility upgrade has been prepared separately from the NOI because of the need to pour the concrete and pavement before the weather turns cold. Please call if you have any questions on this material. Very truly yours, SP Fargineering,Inc.

[PENGINEERING, INC. P.O. Box 848 • Salem, Massachusetts 01970 •Telephone: 978-745-4569 • Fax: 978-745-4881 November 8, 2006 Bruce Thibodeau - Salem Engineering Dept. 120 Washington Street Salem, MA 01970 Re: A&H Auto Exchange, 15 Robinson Road, Salem,Drainage Alteration Plan Truck Scale Dear Mr. Thibodeau, The property owner desires to rebuild the truck scale adjacent to the driveway from Robinson Rd. The truck scale would be used to weigh steel, white metal and other materials that are being recycled in bulk. The entire scale unit is located within the 100' buffer zone of an inland bank and BV W. The unit consists of five concrete pillars, which are in place,a suspended steel frame and steel plate cover ,which are also in place.To complete the installation it is necessary to build an earthen ramp on each side of the scale for accessAnterlocked Jersey barriers would be placed along the ramp to prevent the fill from falling onto the driveway. The ramps on both sides will have curbing and guard rails. Some fill will be placed against the first and second barriers to pin the bottom . The R-bars will be coated steel and epoxy sealer will be used at the headwall base to retard corrosion. The final grading for future runoff control and BMP will change the contours and road elevations, eliminating the Jersey barriers. The top of the existing concrete pillars is at elevation 81.72 while the surrounding grade is 80-81.0. The top of scale is 3' higher than the concrete which means the ramp will require 4-5' of fill at the scale ends. To prevent fill from falling under the scale a concrete headwall 1' thick by 12' wide and 3' high would be constructed against the scale. The structure would be formed on existing grade and pinned to the pillars No excavation is required. The ramp would be 60' long by 10' wide and slope 10%on the Robinson Rd. side and 5%on the house side of the scale. The 10' section closest to the scale would be paved with asphalt underlain with 6" of '/d' crushed stone. The remainder of the fill used for the ramp (approx. 50 cubic yards for each side ) would be on-site material consisting of large rock(6"and under)mixed with 3040%sand and gravel and 10% silt as is typical of the fill pile on the property. The material would be placed by an excavator and packed in with the bucket. A track mounted bulldozer would be used to level and compact the ramp. Crushed stone(3/4") and Lynnpac (approx. 40 cubic yards)would be brought to the site and spread on the ramps to stabilize the surface and prevent erosion. A row of hay bales and siltation fence are in place along the brook bank approx. 30-70' from the proposed ramps. This aspect of the facility upgrade has been prepared separately from the NOI because of the need to pour the concrete and pavement before the weather turns cold. The current drainage flow is split between the swale area beside the driveway,and the road itsel£The road flow proceeds to the inter section of Robinson Rd. and then flows south into the brook at the property line.This plan proposes to restore the drainage ditch on the north side of the scale ramps to direct runoff from the ledge (non-impacted)along the north side of the road and to fill the eroded area beside the brook 1-2' to redirect flow away from the brook. The drainage ditch would be extended along the north side of the road by removing 10-15' of ledge and creating a 2-3' wide ditch to carry the runoff approx. 100' to the turn-off downgradient of the brook. This will eliminate the direct discharge into the brook and the final BMP grading will capture all the runoff and direct it into a detention pond as proposed in the NOI application. The peak flows Pre and Post Truck Scale construction are included for review. The Site Plan and sections are enclosed. Please call if you have any questions on this material.

The truck scale would be used to weigh steel,white metal and other materials that are being recycled in bulk. The entire scale unit is located within the 100' buffer zone of an inland bank and BVW. The unit consists of five concrete pillars, which are in place, a suspended steel frame and steel plate cover,which are also in place.To complete the installation it is necessary to build an earthen ramp on each side of the scale for accessAnterlocked Jersey barriers would be placed along the ramp to prevent the fill from falling onto the driveway. The final grading for future runoff control and BMP will change the contours and road elevations, eliminating the Jersey barriers. The top of the existing concrete pillars is at elevation 81.72 while the surrounding grade is 80-81.0. The top of scale is 3' higher than the concrete which means the ramp will require 4-5' of fill at the scale ends. To prevent fill from falling under the scale a concrete headwall 1' thick by 12' wide and 3' high would be constructed against the scale. The structure would be formed on existing grade and pinned to the pillars No excavation is required. The ramp would be 60' long by 10' wide and slope 10%on the Robinson Rd. side and 5% on the house side of the scale. The 10' section closest to the scale would be paved with asphalt underlain with 6" of '/d' crushed stone. The remainder of the fill used for the ramp (approx. 50 cubic yards for each side) would be on-site material consisting of large rock(6" and under)mixed with 30-40% sand and gravel and 10% silt as is typical of the fill pile on the property. The material would be placed by an excavator and packed in with the bucket. A track mounted bulldozer would be used to level and compact the ramp. c J Crushed stone(3/4'� and Lynnpac (approx. 40 cubic yards) would be brought to the site and spread on the ramps to stabilize the surface and prevent erosion. A row of hay bales and siltation fence are in place along the brook bank approx. 30-70' from the proposed ramps. This aspect of the facility upgrade has been prepared separately from the NOI because of the need to pour the concrete and pavement before the weather turns cold. The current drainage flow is split between the swale.area beside the driveway,and the road itself The road flow proceeds-tu-the inter section of Robinson Rd. and then flows south into the brook at the property line.This plan proposes to restore the drainage ditch on the north side of the scale ramps to direct runoff from the ledge (non-impacted) along the north side of the road and to fill the eroded area beside the brook 1-2' to redirect flow away from the brook. This will eliminate the direct discharge into the brook and the final BMP grading will capture all the runoff and direct it into a detention pond as proposed in the NOI application. The Site Plan and sections are enclosed. Please call if you have any questions on this material. Very truly yours, SPP Engineering, Inc. Bruce M.

Chapter 131, Section 40) Instructions and Supporting Materials Instructions for Completing Application WPA Form 1 - Request for Determination of Applicability Please read these instructions before completing the Request for Determination of Applicability(WPA Form 1) for more information on certain items that are not self-explanatory. Purpose of the Request for Determination of Applicability The Request for Determination of Applicability is a process which provides applicants with the option of seeking a determination on the applicability of the Wetlands Protection Act (the Act) to a proposed site or activity. Before filing this form to confirm the boundary delineation of a resource area, the applicant should discuss other delineation review options with the Conservation Commission. The Commission may require the submission of WPA Form 4A(Abbreviated Notice of Resource Area Delineation), WPA Form 3 (Notice of Intent), or WPA Form 4 (Abbreviated Notice of Intent). The applicant is responsible for providing the information required for the review of this application to the issuing authority (Conservation Commission or the Department of Environmental Protection). The submittal of a complete and accurate description of the site and project will minimize requests for additional information by the issuing authority which may result in an unnecessary delay in the issuance of a Determination of Applicability. The issuing authority also may require that supporting materials (plans and calculations) be prepared by professionals including, but not limited to, a registered engineer, registered architect, registered landscape architect, registered land surveyor, registered sanitarian biologist, environmental scientist, geologist, or hydrologist when the complexity of the proposed work warrants specialized expertise. To complete this form, the applicant should refer to the wetlands regulations (310 CMR 10.00)which can be obtained from the Department's web site at www.state.ma.us/dep. Regulations are available for viewing at public libraries and county law libraries across the state, as well as at the Department's Regional Service Centers. Regulations also are available for sale from the State House Bookstore (617.727.2834) and State House Bookstore West (413.784.1378). Completing WPA Form 1 Section B: Determinations.The Request for Determination of Applicability can be used for a variety of purposes. Check one or more of the boxes under the following circumstances. 1 a.To determine whether the Act applies to a particular area of land. Areas subject to jurisdiction are described in the wetlands regulations at 310 CMR 10.02. 1 b. To confirm the precise boundaries of any delineated wetland resource area. NOTE: before checking Tb—, consult the Commission to determine whether it will provide confirmation of wetland resource area boundaries in response to the filing of WPA Form 1. If the request is filed for a determination of Bordering Vegetated Wetlands (BVW) boundary,the Commission may require applicants to file WPA Form 4A (Abbreviated Notice of Resource Area Delineation), WPA Form 3 (Notice of Intent), or WPA Form 4 (Abbreviated Notice of Intent)to obtain confirmation. 1 c. To determine whether the Act applies to work which is planned within a wetland resource area or within the Buffer Zone to a resource area. Work subject to jurisdiction is described in the wetlands regulations at 310 CMR 10.02. Massachusetts Department of Environmental Protection Bureau of Resource Protection —Wetlands Program WPA Form 1 Request for Determination of Applicability) Massachusetts Wetlands Protection Act (M.G.L. Chapter 131, Section 40) Instructions and Supporting Materials 1d. To determine whether the city or town has a local wetlands ordinance or bylaw which applies to any particular area of land and/or to work which is planned within this area of land. le. To determine the scope of alternatives to be considered for work in the Riverfront Area. The scope of alternatives which must be considered for various types of projects in the Rivertront Area is contained in the wetland regulations at 310 CMR 10.58(4)(c)2. In order for the reviewing agency to obtain a complete description of the project site, resource area boundaries must be clearly delineated. Further explanation of Boxes la— le follows. Resource Areas: Boundaries. For boundaries of inland resource areas (including the Rivertront Area, which may be either inland or coastal), refer to subsection (2), "Definitions, Critical Characteristics and Boundaries"for each resource area covered under 310 CMR 10.54— 10.58. For boundaries of coastal resource areas, refer to the definitions in 310 CMR 10.04 and 10.24 for each resource area covered under 310 CMR 10.25— 10.35, as well as in the text of Section 10.25—10.35. The boundary of the Buffer Zone is determined by measuring 100 feet horizontally from those areas specified in 310 CMR 10.02(1)(a). 1 a. Describe the site and, if possible, the boundary of any area that may be subject to protection under the Act (including the Buffer Zone). 1 b. As noted earlier, 1 b, should only be checked with approval of the Conservation Commission. If checked, submit: • plans identifying the precise boundaries of the resource area(s) delineated; • method used to determine the boundaries of Bordering Vegetated Wetland. Note whether the boundary was delineated based on the presence of one or more of the following: • 50% or more wetland indicator plants • Saturated/inundated conditions • Groundwater Indicators • Direct Observation • Hydric soil indicators • For disturbed sites: specific, credible evidence of conditions prior to disturbance. Use one of the methods indicated above to determine the boundaries of Bordering Vegetated Wetlands (BVW). On the form, check all the methods that are used to determine the boundary.These methods are discussed in the wetland regulations at 310 CMR 10.55(2)(c). When undertaking BVW delineations, whether by vegetation alone or by vegetation and other indicators of wetland hydrology, applicants are encouraged to use the Department's BVW Handbook: Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act(1995). This document is available for purchase from the State House Bookstore (617.727.2834) and State House Bookstore West (413.784.1378).The Department encourages applicants to complete the BVW Field Data Form contained in the handbook and submit it with the Request for Determination of Applicability.
