Re: EAI Project#: 12-39501 City Engineer U.S. Biological City of Salem 4 Technology Way 120 Washington Street, 4th Floor Salem, MA Salem, MA 01970 Dear Mr. Knowlton: On behalf of our client, U.S. Biological, Engineering Alliance, Inc. (EAI) is pleased to submit the following for your review regarding the above referenced project: • One (1) copy of a plan entitled "As-Built Plan" prepared by Leblanc Survey Associates, Inc. and dated December 17, 2012. • One (1) copy of a letter by Roome & Guarracino, LLC Consulting Structural Engineers dated January 21, 2013. Representatives from EAI have been on-site at various times since June, 2012 to witness construction activities at the subject property. Based on our review of the enclosed As-Built Plan and inspection of the site, we find the project to have been constructed in substantial compliance with the approved plans, Planning Board Decision and Order of Conditions issued by the Salem Conservation Commission. The As-Built plan illustrates some deviations from the approved plans; however, based on our review, we feel that overall the plan is in substantial compliance with all approvals and generally accepted engineering practices. The deviations include the following: • CB-2 shown on the approved plan was eliminated and replaced with a high point and CB- 3 was shifted to the north. Although this results in a slight change to the grading and drainage, all storm water runoff generated from the site is captured on-site, treated and discharged to the proposed storm water detention facility. The storm water detention facility was built in accordance with the approved plan. In addition, the slopes of all drainage pipes meet or exceed the designed values (many were designed at 0.05 ft/ft, and most were constructed at 0.08 ft/ft). Based on our review, the storm water management system is functioning as designed and meets the goals of the original drainage design. • The transformer and generator were relocated from the area shown on the approved plan (South side of building)to the south side of the parking lot. The relocation of this equipment does not appear to have an impact on the layout of the site. The additional parking spaces that were added to the rear of the building offset the spaces that were lost due to the relocation of the generator and transformer. • The landscaped island to the rear of the building is smaller than the previously approved plan. Although this area is smaller than shown on the original plan, all storm water generated from the site is captured, treated and discharged to the down gradient storm water facility. The storm water detention facility has ample capacity to handle this modest increase in impervious area. Mr. David Knowlton, P.E. Page 2 January 31, 2013 • A stone wall was constructed on the northerly side of the site in lieu of the modular block wall and a 1:1 stone slope was constructed on the south side of the parking lot in lieu of the proposed ledge cut. The stone wall and rip rap slope were inspected by Roome & Guarracino, LLC Consulting Structural Engineers and determined to be structurally stable and adequate. Overall, the site was found to be stable, well constructed and functioning as the original design and approvals intended. We are hopeful that upon your review of the site and this information, a recommendation for a final occupancy permit may be granted for this project.

I highly recommend having a representative present at this meeting in order to address the commission's questions and concerns. In the meantime, I have the following comments: 1. Due to snow cover, I could not verify that crushed stone was installed at the base of the detention basin or that it had been loamed and seeded. The commission needs to know that the basin was built in accordance with the approved plans. 2. In patches around the basin where snow has melted, I couldn't see grass. The commission will need to either see that grass is growing or have an arrangement in place to guarantee that grass will take hold. 3. If the site is stabilized, erosion controls should be removed. 4. The commission will want the order of conditions for the Technology Way (64-522) utility trench to be closed out. That is, that order must be recorded, all of the conditions complied with, and a certificate of compliance obtained. Please let me know if you have further questions.

We have some issues concerning the property located at 4 Technology Way and we have decided to bring.these issues forward now. During Farfard's clearing & grading of the industrial park, they had brought the buildable portion of their property, to the same elevation as the rear of our property(see Photo 1). We understand, for your reasons, you required that water run off from 4 Technology Way be routed through the storm drain system at Technology Way. We concur as we do not want their water run off entering our property either. We assume that is why Farfard had then raised the topography of their lot. They did so by delivering a large amount of soil and spreading it out over their property in order to grade their topography to a considerably higher elevation where their property abuts ours. You may not be aware that, in doing so, Farfard had spread some of this soil over the stone boundary that had remained after their first grading (see Photo 2). This stone boundary, now covered, had continued along the same line as a fieldstone boundary that delimits their property from ours. We state that, we reserve the right that if and when alterations are to be made to our topography, they would be in a manner acceptable to us and at a time of our choosing. We are displeased that Farfard had altered this, though small, portion our topography, regardless of their intentions in this act. Second, since Farfard had raised their topography above ours, no retaining wall had been placed against the edge of this higher elevation of soil (see Photo 2 again) which is technically required. Without a wall in place, their soil will spread further onto our property from the compressing and squeezing out of the soil caused by the motion of construction equipment during future construction, and from the continuous changing weight distribution of the future parking lot along that edge, and also from weathering against that open edge. All of the above will result in an erosion and a lessening of the current slope of the grade along this edge of their property, which may also be of concern to you. MMBUTTERM7d27 f Ultimately we seek correction of these conditions as follows: 1) The removal of the soil that currently extends onto our property. 2) The construction of a wall, on their property, to retain their soil. We would assume that customarily, the seller being the cause of, would be responsible for, regardless of any potential buyer, and in this situation, the most skilled and able to make these corrections; would offer to make these corrections prior to the property's sale, so as not to hinder a buyer's efforts. Though now that the seller and buyer are under agreement, they could re-negotiate their terms to include these corrections, we hope, amicably, and swiftly, if they have not already done so. So, for the present: We ask that the buyer& seller determine which party will be responsible to make these corrections. We ask for the party assuming these corrections to provide us with a written agreement stating that the corrections will be made within two years, or prior to further development, whichever occurs first; in lieu of immediate correction. We.nckAr the City Of Salem to attach a proviso onto the building permit requiring that these corrections are to be made prior to further development, and that they provide us with the written agreement to correct, stated above. We pray that the City Of Salem will consider our requests and concur with us. Sincerely, George J.

Portions of the site have been disturbed by prior grading activities and the construction of Technology Way. The proposed project ' is the construction of a two story structure and associated parking and utilities to service the building. ' Drainage Areas The property consists of about 4.77 acres. The drainage areas subdivide into several drainage areas. These drainage areas are shown on Figures 1 and 2,the Watershed Plans ' for Pre- and Post-Development conditions. The figures are found in the attached pocket at the back of this report. For purposes of this study, the Pre-Development condition is comprised of two drainage ' areas. Drainage area DA-1 is composed of drainage within the site that flows to the wetland area at the easterly portion of the site. Drainage area DA-2 is composed of drainage within the site that flows to the wetland area at the northerly portion of the site. For the Post-Development condition seven drainage areas are considered instead of the two areas discussed in the pre-development condition. These additional areas consider ' the proposed building,parking areas, drainage facilities and remaining open space.. Table 2, gives information on post development drainage areas. Figure 2 shows their location. The times of concentration and travel paths for the pre- and post-development drainage ' areas are depicted on Figures 1 & 2 in the attached pocket at the back of this report.

The development has been planned to attenuate runoff on site through a sediment forebay and infiltration/detention basin.Non structural measures including ' pollution prevention and source reduction through use of street and parking lot sweeping are included in the operations and maintenance plan. Storm Runoff Volumes for Water Quality ' Calculations for storm water runoff for water quality have been based on 0.5 inches of runoff multiplied by the total impervious area of the post-development site. Table 3 ' presents the results of these calculations. As shown, total impervious area for this project post-development increases to about 2.624 acres. Of this figure, about 0.994 acres is from rooftops. Volume of storm water runoff for water quality Post Development totals about 0.068-acre feet (2,958 cubic feet). Which is proposed to be routed to a sediment forebay for pretreatment prior to discharging to the detention/infiltration basin.

As noted in the Checklist, cursor-do not the Stormwater Report must contain the engineering computations and supporting information set forth in use the return key. Volume 3 of the Massachusetts Stormwater Handbook. The Stormwater Report must be prepared and certified by a Registered Professional Engineer(RPE) licensed in the Commonwealth. The Stormwater Report must include: • The Stormwater Checklist completed and stamped by a Registered Professional Engineer(see page 2) that certifies that the Stormwater Report contains all required submittals.' This Checklist is to be used as the cover for the completed Stormwater Report. • Applicant/Project Name Project Address • Name of Firm and Registered Professional Engineer that prepared the Report • Long-Term Pollution Prevention Plan required by Standards 4-6 • Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan required by Standard 82 • Operation and Maintenance Plan required by Standard 9 In addition to all plans and supporting information, the Stormwater Report must include a brief narrative ' describing stormwater management practices, including environmentally sensitive site design and LID techniques, along with a diagram depicting runoff through the proposed BMP treatment train. Plans are required to show existing and proposed conditions, identify all wetland resource areas, NRCS soil types, critical areas, Land Uses with Higher Potential Pollutant Loads (LUHPPL), and any areas on the site where infiltration rate is greater than 2.4 inches per hour. The Plans shall identify the drainage areas for both existing and proposed conditions at a scale that enables verification of supporting calculations. As noted in the Checklist, the Stormwater Management Report shall document compliance with each of the Stormwater Management Standards as provided in the Massachusetts Stormwater Handbook. The soils evaluation and calculations shall be done using the methodologies set forth in Volume 3 of the Massachusetts Stormwater Handbook. To ensure that the Stormwater Report is complete, applicants are required to fill in the Stormwater Report Checklist by checking the box to indicate that the specified information has been included in the Stormwater Report. If any of the information specified in the checklist has not been submitted, the applicant must provide an explanation. The completed Stormwater Report Checklist and Certification must be submitted with the Stormwater Report. ._......- T _ 'The Stormwater Report may also include the Illicit Discharge Compliance Statement required by Standard 10. If not included in the Stormwater Report,the Illicit Discharge Compliance Statement must be submitted prior to the discharge of stormwater runoff to the post-construction best management practices. 3 For some complex projects,it may not be possible to include the Construction Period Erosion and Sedimentation Control Plan in the Stormwater Report. In that event,the issuing authority has the discretion to issue an Order of Conditions that approves the project and includes a condition requiring the proponent to submit the Construction Period Erosion and Sedimentation Control Plan before commencing any land disturbance activity on the site. swcheck.doc•04/01/08 Stormwater Report Checklist•Page 1 of 8 ' Massachusetts Department of Environmental Protection Bureau of Resource Protection - Wetlands Program Checklist for Stormwater Report B. Stormwater Checklist and Certification The following checklist is intended to serve as a guide for applicants as to the elements that ordinarily need to be addressed in a complete Stormwater Report. The checklist is also intended to provide ' conservation commissions and other reviewing authorities with a summary of the components necessary for a comprehensive Stormwater Report that addresses the ten Stormwater Standards. ' Note: Because stormwater requirements vary from project to project, it is possible that a complete Stormwater Report may not include information on some of the subjects specified in the Checklist. If it is determined that a specific item does not apply to the project under review, please note that the item is not applicable(N.A.)and provide the reasons for that determination. 1 A complete checklist must include the Certification set forth below signed by the Registered Professional Engineer who prepared the Stormwater Report. ' Registered Professional Engineer's Certification I have reviewed the Stormwater Report, including the soil evaluation, computations, Long-term Pollution ' Prevention Plan, the Construction Period Erosion and Sedimentation Control Plan (if included), the Long- term Post-Construction Operation and Maintenance Plan, the Illicit Discharge Compliance Statement(if included)and the plans showing the stormwater management system, and have determined that they i ' have been prepared in accordance with the requirements of the Stormwater Management Standards as further elaborated by the Massachusetts Stormwater Handbook.

Portions of the site have been disturbed by prior grading activities and the construction of Technology Way. The proposed ' project is the construction of a two story structure and associated parking and utilities to service the building. Portions of the development will take place within the buffer zone of a Bordering Vegetative Wetland. No wetland alterations are ' proposed as part of this development. Upon completion of the project the proponent "United States Biological' will own and have operational control over the site. 1 1 r r r r r r r r 3 1 COMPREHENSIVE SPILL MANAGEMENT PLAN 1 UNITED STATES BIOLOGICAL IN SALEM, MASSACHUSETTS DATE: 10 SEPTEMBER 2010 i i 4 ' Pollution Prevention and Spill Management Team: ' Pollution Prevention and Spill Management Team will be under the supervision of Project proponent United States Biological. The proponent will identify ' appropriate personal on site to implement this plan. Comprehensive Spill Management Plan: ' Properly managing hazardous and toxic substances and petroleum products in ' the project site will greatly reduce the potential for pollution by these substances. Good housekeeping practices, along with proper use and storage of these ' substances, form the basis of proper management of potentially harmful substances. The proper use of materials and equipment, along with general common sense, greatly reduce the potential for contaminating resource areas. Following is a list ' of good housekeeping practices to be implemented. • Storage of hazardous materials, chemicals, fuels, and oils and fueling of ' equipment will not take place within 100 feet of any drainage, wetland, ' stream, or other water feature. • Materials stored on-site will be stored in their appropriate containers ' Products will be kept in their original containers with the original manufacturer's label. Substances will not be mixed with one another. • The entire product will be used before its container is discarded. 1 5 1 • Manufacturer's recommendations for proper use and disposal of a product will be followed. • If surplus product must be disposed of, the manufactures or the local and ' state recommended methods for proper disposal will be followed. Because of the chemical composition of certain products, specific handling and storage procedures are required to promote the safety of handlers and prevent releases of the product to soil and receiving waters. Care will be taken to follow all directions and warnings for products used on the site. All pertinent information 1 can be found on the Material Safety Data Sheet (MSDS) for each product. The ' MSDS will be kept for each product container. On-site vehicles will be monitored for fluid leaks and will receive regular maintenance to reduce the chance of leakage. Petroleum products will be stored in tightly sealed containers that are clearly labeled. t 1 ' In addition to the material management practices discussed above, the following spill control and clean up practices will prevent pollution. t • Spills will be contained and cleaned up immediately upon discovery. ' • Manufacturer's methods for spill cleanup of a material will be followed as described on the MSDSs. 6 I � I ' . Materials and equipment needed for cleanup will be kept readily available on-site. Equipment to be on-site will include-but not limited to-brooms, dust pans, shovels, granular absorbents, sand, sawdust, absorbent pads ' and plastic and metal trash containers, gloves, and goggles. ' . Spill kits, traps, will be kept on site. • Personnel will be made aware of cleanup procedures, the location of spill , ' cleanup equipment, and proper disposal procedures. t . Toxic, hazardous, or petroleum product spills will be reported to the appropriate federal, state, and local agencies as regulations require. ' . Spills will be documented and a record of the spills will be kept. ' . If a spill occurs that is reportable to the federal, state, the proponent will be responsible for the reports. - ' • All spills are reportable to the local town agencies; the proponent will be - ' responsible for the reports. ' If a spill is reportable, the proponent will notify: Federal — EPA National Response Center ' (800) 424-8802 State— Department of Environmental Protection ' (888) 304-1133 All spills are reportable, the contractor's superintendent will notify: Local - Salem Conservation Commission (978) 619-5685 ' Salem Fire Department (978) 744-6990 Salem Department of Public Works ' (978) 744-3302 7 1 A written description of reportable releases will be submitted to the appropriate ' agencies. This submittal must include a description of the release, including the type of material and an estimate of the amount spilled, the date of the release, an ' explanation of why the spill occurred, and a description of the steps taken to ' prevent and control future releases. ' All waste material will be collected and stored in a secure container and removed ' from the project site. The waste container will be inspected regularly, and the contents will be discarded properly by the proponent. No waste oil or other ' petroleum-based product will be disposed of on-site, but will be removed off-site ' for proper disposal. Any Litter generated on site will be picked up and properly discarded. 1 s 1 DRIVEWAYS AND PARKING AREAS: ' ACTION: Sweeping ' FREQUENCY: Bi-Annually ' DESCRIPTION: Driveways and paved parking areas shall be swept bi- annually.
