This Order does not grant any property rights or any exclusive privileges; it does not authorize any injury to private property or invasion of property rights. However,the NACC, agent of the NACC or the Department of Environmental Protection(DEP) reserves the right to enter and inspect the property at all reasonable times until a Certificate of Compliance is issued, to evaluate compliance with this Order of Conditions, the Act (310 CMR 10.00), the North Andover Wetland ByLaw and Regulations, and may require any information, measurements,photographs, observations, and/or materials, or may require the submittal of any data or information deemed necessary by the NACC for that evaluation. Further,work shall be halted on the site if the NACC, agent or DEP determines that any of the work is not in compliance with this Order of Conditions. Work shall not resume until the NACC is satisfied that the work will comply and has so notified the applicant in writing. 26. This Order does not relieve the permittee or any other person of the necessity of complying with all other applicable federal, state or local statutes, ordinances, by-laws or regulations. - 27. The work authorized hereunder shall be completed within three years from the date of this order. 28. This Order may be extended by the issuing authority for one but not more than two periods of up to one year each upon application to the issuing authority at least thirty days (30) prior to the expiration date of the Order (Refer to Section 8.3 of the North Andover Wetland Regulations). 29. The NACC reserves the right to amend this Order of Conditions after a legally advertised public hearing if plans or circumstances are changed or if new conditions or information so warrant. 30. Where the Department of Environmental Protection (DEP) is requested to make a determination and to issue a Superseding Order, the Conservation Commission shall be a party to all agency proceedings and hearings before the Department. 31. Any future project which proposes a wetland crossing in order to access certain portions of the property will not be qualified as a limited project roadway under 310 CMR 10.53(e). 32. The following wetland resource areas are affected by the proposed work: Buffer Zone to Isolated and Bordering Vegetated Wetland (IVW/BVW), Riverfront Area and Inland Bank. These resource areas are significant to the interests of the Act and Town ByLaw as noted above and therein. The applicant has not attempted to overcome the presumption of significance of these resource areas to the identified interests. 242-1588,464 Appleton Street subdivision 3 NACC 5/10/2013 DEP FILE #242 - 1588 33. The NACC agrees with the applicant's delineation of the wetland resource areas on the site as shown on the plans dated referenced herein and approved in the ORAD issued under DEP File #242-1556. Mean Annual High Water of Mosquito Brook (downstream of Blue Ridge Road) is only shown on Riverfront Analysis Plans Figures A-D referenced herein. Mean High Water Delineation will be added to the as-built plan prior to the issuance of a Certificate of Compliance (COC). 34. The NACC finds that the intensive use of the upland areas and buffer zone proposed on this site will cause further alteration of the wetland resource areas. In order to prevent any alteration of wetland resource areas a twenty five foot (25') No- Disturbance Zone and a fifty foot 50') No-Construction Zone shall be established from the edge of Bordering Vegetated Wetland (BVW), Inland Bank and Isolated Vegetated Wetland. The Conservation Administrator and/or other agents of the NACC do not have the authority to waive these setbacks as established under the local bylaw. No disturbance of existing grade, soils or vegetation is permitted in the No-Disturbance zone. (See Section 3.2 &Appendix F of the local Regulations). r-- 35. f T he NACC.findis the.applicant`s proposal!for restoration of'the:stream:flow through four box culverts (two of which are i paired);under,Blue Ridge,Road and the? i'nstal'lation of improved storm,water management(in B'llue,Raedge�R�oadl) as.shown on the herein referenced Plan,,to;be adiequate�mitigation and improvements to the Riverfront of Mosquito Brook. 36. This document shall be included in all construction contracts, subcontracts, and specifications dealing with the work proposed and shall supersede any conflicting contract requirements. The applicant shall assure that all contractors, subcontractors, and other personnel performing the permitting work are fully aware of the permits terms and conditions. Thereafter, the contractor will be held jointly liable for any violation of this Order resulting from failure to comply with its conditions. 37.

Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan i Revised March 12, 2013 STORMWATER MANAGEMENT CONTROLS The purpose of this section is to identify the types of temporary and permanent erosion and sediment controls that will be used during construction activities. The controls will provide soil stabilization for disturbed areas and structural controls to divert runoff and remove sediment. This section will also address control of other potential storm water pollutant sources such as construction materials (paints, concrete dust, solvents, and plaster), waste disposal, control of vehicle traffic, and sanitary waste disposal. 2.4 Temporary and Permanent Erosion Control Practices A list of best management practices (BMPs) is included as Table 3; a number of the BMPs listed have been developed to serve as post-construction storm water controls. 2.5 Site Wide Control Measures To prevent soil from washing into adjacent resource areas the following BMPs will be implemented: 2.5.1 Silt socks, silt fence, and/or straw hay bale barriers will be placed along the perimeter of the area to be cleared and graded before any clearing or grading takes place. 2.5.2 Check dams shall be installed above the upgradient end of all driveway culverts as soon as the drainage swales are brought to rough grade. 2.5.3 Influent.points to the infiltration basins will be stabilized with rip- rap to avoid washout. Check dams shall be installed below the rip-rap. 2.5.4 To the extent practical, all cleared and graded soils will be sloped to the roadway drainage swales. Disturbed areas are to j be brou'ght to final finished grade and stabilized. Bare ground that can not be permanently stabilized within 30 days shall be stabilized with mulch, hay or jute mats. 2.5.5 Soil stockpiles are to be surrounded by silt fencing, and shall be i covered with erosion control blanket or stabilized with vegetation if they are to remain for periods greater than 14 days. i Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan Revised March 12, 2013 2.6.5 Fertilizers will be applied only in the minimum amounts recommended by the manufacturer. 2.6.6 Fertilizers will be worked into the soil to limit exposure to storm water. 2.6.7 Fertilizers will be stored in a covered shed and partially used bags will be transferred to a sealable bin to avoid spills. 2.6.8 All vehicles on site will be monitored for leaks and receive regular preventative maintenance to reduce the chance of leakage. 2.6.9 Petroleum products will be stored in tightly sealed containers which are clearly labeled. 2.6.10 Spill kits will be included with all fueling sources and maintenance activities. 2.6.11 Any asphalt substances used on-site will be applied according to the manufacturer's recommendation. 2.6.12 Sanitary waste will be collected from portable units a minimum of three times a week to avoid overfilling. 2.6.13 A covered dumpster will be used for all waste materials. 2.6.14 All paint containers and curing compounds will be tightly sealed and stored when not in use. Excess paint will not be discharged into the storm sewers, but will be properly disposed of in accordance to the manufacturer's instructions. 2..6.15 Materials and equipment necessary for spill clean up will be kept in the temporary material storage trailer on-site. Equipment will include, but not be limited to, brooms, dust pans, mops, rags, gloves, goggles, kitty litter, sand, saw dust, and plastic and metal trash containers. 2.6.16 Spray guns will be cleaned on a removable tarp. 2.6.17 All spills.Will be cleaned up upon discovery. Spills large enough to reach the storm water treatment system will be reported to the engineer, environmental monitor, North Andover Conservation Commission and the Nation Response Center at (800) 424-8802. 2.6.18 Concrete trucks will not be allowed to wash out or discharge surplus concrete or drum wash water on the site. 2.6.19 Form release oil used-for building foundations will be applied over a pallet covered with an absorbent material to collect excess fluid. The absorbent material will be replaced and disposed of properly when saturated. 2.6.20 When testing/cleaning water supply lines, the discharge from the tested pipe(s)will be collected and conveyed to a completed section of the storm sewer for discharge into the sedimentation basin. Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan Revised March 12, 2013 2.7 Coordination of BMPs with Construction Activities Structural BMPs will be coordinated with construction activities so the BMP is in place before construction begins. The following BMPs will be coordinated with construction activities: f 2.7.1 The temporary perimeter controls (silt socks or silt fence and hay bales)will be installed before any clearing and grading begins. j 2.7.2 Clearing and grading will not occur in an area until it is necessary for construction to proceed. 2.7.3 The stabilized construction site entrance will be constructed before clearing and grading begins. j 2.7.4 The infiltration basins will be constructed prior to the construction of the upstream drainage system. 2.7.5 Once construction activity ceases permanently in an area, that area will be stabilized with permanent seed and mulch. 2.7.6 After the'entire site is stabilized, the accumulated sediment will be removed from the sediment basins or other structural BMPs. 2.7.7 The temporary perimeter controls (silt socks, silt fence, and hay bales)will not be removed until all construction activities at the site are complete and soils have been stabilized. 3.0 CERTIFICATION OF COMPLIANCE WITH FEDERAL, STATE AND LOCAL REGULATIONS i This Operation and Maintenance Plan reflects the storm water management requirements of the Town of North Andover and the Commonwealth of Massachusetts, as well as the requirements of the US EPA's National Pollutant Discharge Elimination System (NPDES) permit. There are no other applicable State or Federal requirements for sediment and erosion site plans (or permits) or stormwater management site plans (or permits). 4.0 INSPECTION AND MAINTENANCE OF STORMWATER MANAGEMENT CONTROLS: Visual inspections of cleaned and graded areas should be performed weekly(silt sock/silt fence/ha :bale barriers should be inspected daily b the General Y P Y Y Contractor)and within 24 hours of a rainfall event of 0.25 inches or greater. The inspection will be conducted:by the Erosion Control monitor. The inspection will, at _. a minimum, verify that the structural BMPS listed in Table 3 of this plan are in good condition and are effectively minimizing erosion. Any entrapped silt shall be removed to an area outside of the buffer zone and wetland resource areas; silt i i Regency Place North Andover, Mass. Pollution Prevention and operations and Maintenance Plan Revised March 12, 2013 socks, silt fence, and hay bales shall be replaced as necessary. The inspection will also verify that the procedures used to prevent storm water contamination from construction materials and petroleum products are effective. The maintenance inspection report will be made after each inspection. Copies of the report forms to be completed by the Erosion Control Monitor are provided in Appendix C of this report. Completed forms will be maintained on-site during the entire construction project. Copies of the forms will be sent weekly to the environmental monitor, design engineer, and North Andover Conservation Commission. Following construction, the completed forms will be retained at the general contractor's office for a minimum of one year. If construction activities or design modifications are made to the site plan which could impact storm water, this plan will be amended appropriately. The amended plan will have a description of the new activities that contribute to the increased pollutant loading and the planned source control activities. 4.1 Construction Phase 4.1.1 Erosion Control shall be inspected and maintained/reinforced on a daily basis during construction. 4.1.2 Sediment built up along sedimentation barriers will be removed when it has reached 6 inches in depth. 4.1.3 Sedimentation barriers will be inspected for depth of sediment, for tears, to see if the fabric is securely attached to the fence posts,'and to see that fence posts are securely in the ground. 4.1.4 All exposed soil finish surfaces shall be immediately landscaped and stabilized; or loamed, seeded and mulched with a layer of mulch hay. Outside of the growing season, surfaces shall be covered with a layer of mulch hay until climate conditions allow for seeding. 4.1.5 Immediately upon installation of any catch basin or storm drain, erosion control devices shall be set and staked around the inlet to prevent sediment from entering the drainage system prior to paving. After binder pavement Siltsacks shall be installed in each catch basin and shall be maintained until all upgradient contributing areas are stabilized 4.1.6 All stockpile areas are to be covered if they are to remain for over'14 days, and should have silt fencing staked around the base. 4.1.7 During construction, all drainage structures shall be cleaned on an as�needed basis and/or after heavy rainfalls. Prior to the placement of any impervious materials on site, all drainage structures, swales, and infiltration basins shall be properly installed and functional. I Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan Revised March 12, 2013 4.1.8 The infiltration areas will be inspected for sediment, and built up sediment will be removed upon identification. The proposed infiltration basins are not intended to be used as sedimentation basins during construction. The check dams in the upgradient swales shall be the primary sediment traps during construction. If any sediment builds up in an infiltration basin the affected area shall be excavated and rebuilt to preserve the infiltrative capacity of the basin. 4.1.9 During construction (after paving) street sweeping shall be performed on a monthly basis to remove sediment before it enters the catch basins and drainage system. 4.1.10 Temporary and permanent seeding will be inspected for bare spots, washouts, and healthy growth. 4.1.11 The sediment forebay will be inspected for depth of sediment and built up sediment will be removed when it reaches 6 inches in depth. 4.2 Post-Construction: I The following maintenance schedule for stormwater controls shall be established in accordance with Table 3 of this plan. 4.2.1 Deep Sump, Hooded Catch Basins & Stormceptor 4.2.1.1 Inspect units four (4) times per year and at the ' end of the foliage and snow removal seasons. 4.2.1.2 Sediment shall be removed four(4)times per year or whenever the depth of sediment is greater than or equal to one half the depth from the bottom of the invert of the lowest pipe in the. basin. Removal should be completed with either a clamshell bucket or vacuum truck, a vacuum truck is the preferred method for removal. 4.2.2 Grassed Swales 4.2.2.1 Inspect the swales twice per year for slope integrity, soil moisture, vegetative health, soil ' stability, soil compaction, soil erosion, ponding, and sediment accumulation. 4.2.2.2 Mow channels at least once per month during the growing season. Do not cut the grass shorter than three to four inches. Keep grass height under 6 inches to maintain the design depth necessary to serve as a conveyance. 4.2.2.3 Remove sediment and debris manually at least i u Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan Revised March 12, 2013 once per year. Re-seed periodically to maintain the dense growth of grass vegetation. 4.2.3 Infiltration Basins 4.2.3.1 Inspect after every major storm for the first few months to ensure it is stabilized and functioning properly and if necessary take corrective action. Note how long water remains standing in the basin after a storm; standing water within the basin 48 to 72 hours after a storm indicates that the infiltration capacity may have been overestimated. If the ponding is due to clogging, immediately address the reasons for the clogging (such as upland sediment erosion, excessive compaction of soils, or low spots) 4.2.3.2 Thereafter, inspect the infiltration basin at least twice per year. Important items to check during the inspection include: Signs of differential settlement, Cracking, Erosion, Leakage in the embankments, Tree growth on the embankments, Condition of riprap, Sediment accumulation, and the health of the turf. 4.2.3.3 At least twice a year, mow the buffer area, side slopes, and basin bottom. Remove grass clippings and accumulated organic matter to prevent an impervious organic mat from forming. Remove trash and debris at the same time. 4.2.3.4 Remove sediment at inlet once per year or as needed. 4.2.3.5 Use deep tilling to break up clogged surfaces, and re-vegetate immediately. Remove sediment from the basin as necessary, but wait until the floor of the basin is thoroughly dry. Use light equipment to remove the top layer so as to not compact the underlying soil. Deeply till the remaining soil, and re-vegetate as soon as possible. 4.2.3.6 Remove sediment from forebay once per year. C t Regency Place j North Andover, Mass.

Any future project which proposes a wetland crossing in order to access certain portions of the property will not be qualified as a limited project roadway under 310 CMR 10.53(e). 32. The following wetland resource areas are affected by the proposed work: Buffer Zone to Isolated and Bordering Vegetated Wetland (IVW/BVW), Riverfront Area and Inland Bank. These resource areas are significant to the interests of the Act and Town ByLaw as noted above and therein. The applicant has not attempted to overcome the presumption of significance of these resource areas to the identified interests. 33. The NACC agrees with the applicant's delineation of the wetland resource areas.on the site as shown on the plans dated referenced herein and approved in the ORAD issued under DEP File #242-1556.

Mean High Water Delineation will be added to the as-built plan prior to the issuance of a Certificate of Compliance (COC). 34. The NACC finds that the intensive use of the upland areas and buffer zone proposed on this site will cause further alteration of the wetland resource areas. In order to prevent any alteration of wetland resource areas a twenty five foot(25')No- Disturbance Zone and a fifty foot(50') No-Construction Zone shall be established from the edge of Bordering Vegetated Wetland (BVW), Inland Bank and Isolated Vegetated Wetland. The Conservation Administrator and/or other agents of the NACC do not have the authority to waive these setbacks as established under the local bylaw. No disturbance of existing grade, soils or vegetation is permitted in the No-Disturbance zone.

The absorbent material will be replaced and disposed of properly when saturated. 2.6.20 When testing/cleaning water supply lines, the discharge from the tested pipe(s)will be collected and conveyed to a completed section of the storm sewer for discharge into the sedimentation basin. Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan Revised March 12,2013 socks, silt fence, and hay bales shall be replaced as necessary. The inspection will also verify that the procedures used to prevent storm water contamination from construction materials and petroleum products are effective. The maintenance inspection report will be made after each inspection. Copies of the report forms to be completed by the Erosion Control Monitor are provided in Appendix C of this report. Completed forms will be maintained on-site during the entire construction project. Copies of the forms will be sent weekly to the environmental monitor, design engineer, and North Andover Conservation Commission. Following construction, the completed forms will be retained at the general contractor's office for a minimum of one year. If construction activities or design modifications are made to the site plan which could impact storm water, this plan will be amended appropriately. The amended plan will have a description of the new activities that contribute to the increased pollutant loading and the planned source control activities. 4.1 Construction Phase 4.1.1 Erosion Control shall be inspected and maintained/reinforced on a daily basis during construction. 4.1.2 Sediment built up along sedimentation barriers will be removed when it has reached 6 inches in depth. 4.1.3 Sedimentation barriers will be inspected for depth of sediment, for tears, to see if the fabric is securely attached to the fence posts,and to see that fence posts are securely in the ground. 4.1.4 All exposed soil finish surfaces shall be immediately landscaped and stabilized; or loamed, seeded and mulched with a layer of mulch hay. Outside of the growing season, surfaces shall be covered with a layer of mulch hay until climate conditions allow for seeding. 4.1.5 Immediately upon installation of any catch basin or storm drain, erosion control devices shall be set and staked around the inlet to prevent sediment from entering the drainage system prior to paving. After binder pavement Siltsacks shall be installed in each catch basin and shall be maintained until all upgradient contributing areas are stabilized 4.1.6 All stockpile areas are to be covered if they are to remain for over'14 days, and should have silt fencing staked around the base. 4.1.7 During construction, all drainage structures shall be cleaned on an as needed basis and/or after heavy rainfalls. Prior to the placement of any impervious materials on site, all drainage structures, swales, and infiltration basins shall be properly installed and functional. Regency Place North Andover, Mass. Pollution Prevention and Operations and Maintenance Plan Revised March 12, 2013 once per year. Re-seed periodically to maintain the dense growth of grass vegetation. 4.2.3 Infiltration Basins 4.2.3.1 Inspect after every major storm for the first few months to ensure it is stabilized and functioning properly and if necessary take corrective action. Note how long water remains standing in the basin after a storm; standing water within the basin 48 to 72 hours after a storm indicates that the infiltration capacity may have been overestimated. If the ponding is due to clogging, immediately address the reasons for the clogging (such as upland sediment erosion, excessive compaction of soils, or low spots) 4.2.3.2 Thereafter, inspect the infiltration basin at least twice per year. Important items to check during the inspection include: Signs of differential settlement, Cracking, Erosion, Leakage in the embankments, Tree growth on the embankments, Condition of riprap, Sediment accumulation, and the health of the turf. 4.2.3.3 At least twice a year, mow the buffer area, side slopes, and basin bottom. Remove grass clippings and accumulated organic matter to prevent an impervious organic mat from forming. Remove trash and debris at the same time. 4.2.3.4 Remove sediment at inlet once per year or as needed. 4.2.3.5 Use deep tilling to break up clogged surfaces, and re-vegetate immediately. Remove sediment from the basin as necessary, but wait until the floor of the basin is thoroughly dry. Use light equipment to remove the top layer so as to not compact the underlying soil. Deeply till the remaining soil, and re-vegetate as soon as possible. 4.2.3.6 Remove sediment from forebay once per year. Regency Place North Andover, Mass.
