It is anticipated this plan will be fully implemented by a single company specializing in the stormwater maintenance of underground systems. PERMANENT STORMWATER MEASURES Permanent stormwater measures are all those structural or non-structural practices intended to reduce or eliminate stormwater degradation and site erosion following construction completion, site stabilization and property occupancy. Specifically,these permanent measures are purposefully chosen, sized and placed in such a manner that will result in measureabie stormwater quality, volume and velocity controls. Ultimately, the I monitoring and successful operations of all permanent stormwater measures, shall be the Property Manager's i responsibility. it is highly recommended that a third party stormwater agent is contracted by the property manager for operation and maintenance responsibilities. Any and all such contractual arrangements will be added to the final Princeton at North Andover Apartment Homes and Forgetta Retail,/Commercial Center Stormwater Operations and Maintenance Plan, as an addendum with continual updates, business registrations, certifications l and proper insurances,as applicable.

Landscape contractors, pest management contractors and general maintenance staff shall follow all applicable product manufacturer,state and federal guidelines for the storage and handling of materials and chemicals on site. All debris shall be collected and disposed of offsite in a legal manner. Temporary snow storage may be permitted, in accordance with the approved permit plans in the pre-determined locations only. Yard waste and snow is prohibited from being deposited in or near the on site wetland resources.These areas include the following: 59 The left side of the entry drive from Osgood Street to the Princeton leasing office. > Behind the pool area > To the east of the parking area on the side of Residential Building D > Behind Building D > Over the wall between Residential Buildings D and E > Behind the garages to the side of Residential Building E > over the wall in the rear parking lot of Residential Building E The wetland resources and jurisdictional 100 foot buffer zones are shown on the figure below. STORMWATER SYSTEMS The permanent Princeton at North Andover Apartment Homes and Forgetta Retail/Commercial Center private stormwater systems are proven, reliable and affective stormwater treatment, storage and infiltration practices. The site is strategically graded to mimic the pre-development natural drainage patterns andl therefore maintains several individual and separate drainage systems. In general, all the clean roof runoff will be collected,stored and infiltrated through underground chamber systems, each with emergency overflows directing excess stormwater in the same locations as naturally occurred prior to development. The associated site access and parking areas are largely conventional bituminous pavement with various curbing types, all promoting gutter line surface flow into deep sum catch basins with outlet hoods. The project's main stormwater practices are underground storage systems, using the "Stormtech" proprietary chamber system and ADS N-12 watertight closed pipe systems. Each of the Stormtech system contains isolator rows with both dedicated inlet and outlet control manholes. Collectively, the chosen stormwater systems will meet or exceed local,state and federal standards as designed,when operated, monitored and maintained properly.

However, due to product knowledge,training andspecialty maintenance equipment re uired, it is strongly y recommended by the design engineer of record,the property manager secure and maintain a long term third party contract with an industry specific trained & licensed professional capable of operating, inspecting and maintaining the system. In general, good housekeeping, common sense responsible site operations and timely maintenance include the following activities: Site Maintenance: The site and all its components shall be kept in a neat, orderly and clean fashion. Routine upkeep ' i shall be performed by either Owner's representatives Property Management Staff and/or their assigned depending on the project's status. Typical site maintenance activities shall include, but not be limited to responsible construction practices, parking lot sweeping using a vacuum sweeper, landscape management including intensive spring and fall season cleaning and building maintenance. Trash Disposol: All common household waste materials will be collected and stored in a securely lidded metal dumpsters housed within lockable enclosure(s), maintained on site by a third party refuse collection agent. All incidental(small)site trash and debris will be deposited in the dumpster by the property manage or their assigned agent(s). The dumpster will be emptied on a regular schedule, prior to being over filled. All residents and property management personnel will be instructed on proper onsite waste disposal practices. in addition to onsite signage,all residents will receive specific onsite disposal services including recycling if applicable within their lease agreement documentation. i S ild Control& Containment: Good housekeeping and spill control practices will be followed to minimize storm water contamination from petroleum products, paints, and cleaning products. All resident vehicles will be routinely monitored for leaks with written notices distributed as required by property management staff. Habitual offenders f will be removed from the site with parking privileges revoked, if necessary. Emergency spill kits will be available on t site with operation and deployment managed by trained property management staff. I Snow ,Removal and Deicing: Snow plowing, removal and deicing operations shall be done under contract with a J reputable firm with experience with maintaining commercial sites with sensitive areas. No snow shall be plowed over retaining walls. Snow shall be placed in landscape areas so as not to damage landscape materials or inhibit vehicle visibility. When snow on site impairs vehicle movement and parking,snow shall be removed from the site and disposed of in accordance with applicable local,state and federal requirements.Deicing chemicals shall be applied in accordance t with standard practices in a responsible manner and only as required. 4 At no time will hazardous or dangerous materials or chemical storage be permitted on premises in any quantity by either property management representatives, tenants or residents.

Stormwater Management System Maintenance Deep Sump Hooded Catch Basins(33Total) The actual removal of sediments and associated pollutants and trash occurs only when inlets or sumps are cleaned out; therefore, regular maintenance is required. The more frequent the cleaning, the less likely sediments will be resuspended and subsequently discharged. In addition, frequent cleaning also results in more volume available for future storms and enhances the overall performance. At a minimum, water quality inlets and deep sumps should be Inspected monthly for general function and four times,per year for sediment levels. Each of the thirty-three (33) catch basins on site are equipped with a four (4)foot deep sump (the area in the catch basin below the elevation of the pipe leaving the basin), The pipe is not visible as It is equipped with a gas/oil hoods but the constant water level in the catch basin generally indicates this elevation. Atape measure can be used to measure the depth from the rim grate to the water level,then the depth of the water can be measured and compared to the four feet.The distance short offour feet equals the sediment level. Catch basins must be pumped when the sediment level exceeds one (1) hoot through the use of a vacuum extractor or once every year. Disposal of the accumulated sediment and hydrocarbons must be in accordance with applicable Kuua|, state, and federal guidelines and regulations. Bay Filter Treatment Units(4total) When BayFilters are initially installed,we recommend that an inspection be performed on the system in the first six (U) months. After that,the inspection cycle shall he semi-annual (twice a year), Easy access assures unobstructed and effortless on-the-spot inspection of any BayFi|t*rsystmm. The vaults shall be cleaned m minimum of once per year using a vacuum truck,The cartridges should be replaced once every three years or whenever the system up gradient of the filter is not draining down completely within 24 to 48 hours following a storm event,whichever is sooner.The drain-down time shall be tracked at least once per year following a storm ufome|nchormore.Thedraindouvnt|mecanheuseduxmnindicatmrastnvvhenthecmrtridgeis"apene^ w|th regard'tqoil &grease removal aswell aothe sediments.

Call BaySaver customer service representative who will provide a list of reliable contractors in the area. The maintenance cycle of the BayFilter system is driven mainly by the actual solids load on the filter. Inspection must be performed twice a year to be certain it is operating correctly. When BayFilter exhibits flows below design levels, the system should be inspected and maintained as soon as practical. The threshold for cartridge replacement should be when that volume is not draining down within 24-48 hours.An estimated replacement frequency of once every three years. j 1 Procedure: ( 1. Remove the manhole covers and open all access hatches. 2. Before entering the system make sure the air is safe per OSHA Standards or use a breathing apparatus. Use low 02, high CO, or other applicable warning devices per regulatory requirements. 3. Using a vacuum truck, remove any liquid and sediments that can be removed prior to entry. 4. Using a small lift or the boom of the vacuum truck, remove the used cartridges by lifting them out. t 5. .Any cartridges that cannot be readily lifted can be easily slid along the floor to a location they can be lifted via a boom lift. 6, When all the cartridges have been removed, it is now practical to remove the balance of the solids and water. Loosen the stainless clamps on the Fernco couplings for the manifold and remove the drainpipes as well. Carefully cap the manifold and the Fernco''s and rinse the floor, washing away the balance of any remaining collected solids. 7. Clean the manifold pipes, inspect, and reinstall. 8. Install the exchange cartridges and close all covers. 9. The used cartridges must be sent back to BaySaver Technologies for exchange/recycling and credit on undamaged units. ADS Solid Pipe Watertight Closed Underground Detention Systems(5 total) Maintenance is required for the proper operation of underground detention areas despite the measures implemented "up stream" of these facilities. Subsurface storage/infiltration systems should be inspected at least once a year following a storm of one inch or more to ensure that they are fully drained within 72 hours. If they are not,corrective action must be taken. Underground detention systems shall be inspected at least once per year to ensure that the systems are t operating as intended. Inspections should be at all inlet manhole inspection ports, at the outlet manholes and system interior inspection ports. > Sediment should be removed from the pipes at the inlet ports,system interior inspection ports and outlet manholes as necessary, and at least once every 5 years. ➢ The outlet structure should be inspected for evidence of clogging or outflow release velocities that are greater than design flow. > Potential problems that should be checked include: failure to drain within 24 hours of a storm event, pavement problems above systems and evidence of groundwater incursion into system indicated by base j flow duringdry periods(defined as no rain for at least 4 days).

During inspections, changes to the detention system or the contributing watershed should be not,ed, as these may affect basin performance. STO0&qTECHISOLATOR ROW/GTOTAL) Routine inspection schedule needs to be established for each individual location based upon site specific variables.The type,of land use (i.e. industrial',commercial', residential), anticipated pollutant load, percent imperviousness, climate, etc.all play a critical role in cletermining the actual frequency of inspection and maintenance practices.At a minimum the Storm-Fechsystem shall be inspected twice a year. Initially,the Isolator Row should be inspected every 3 months for the first year of operation. For sub sequent years,the inspection should be adjusted based upon previous observation of sediment deposition.The Isolator Row incorporates a oum&[nationofstamdardnnmnho|e/slmndstratmg]ca|Vy|ocntedinspectionports (aomeuded).Theinypectionports allow for easy access to the system from the surface, eliminating the need to perform a confined space entry for inspection purposes.

Note how long water remains standing in each system after a storm using a stadia rod through the inspection port located over each system (metal cover to grade);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 by contacting a Professional Civil Engineer.Thereafter, inspect the infiltration BMP at least twice per year.

If they are not, corrective action must be taken. Outlet Structures(15 total) Each of the ADS solid pipe systems and ADS—Stormtech systems have outlet structure (drain manholes)to control the rate of stormwater leaving the system at a controlled rate for various storm events.These manholes are equipped with weir plates dividing the inlet pipe(s) from the outlet pipe.The weir plates have one or more orifices drill in the plate allowing water to leave the system.The outlet structure should be inspected four times a year to see if the orifices are clear of any debris and the manholes is in good condition.There should be no standing water in these structures above the lowest orifice three days after a rain event. Mirrors on poles or cameras may be used to avoid a confined space entry. Follow OSHA regulations for confined space entry if entering manhole Riprap Aprons (3,total) The areas of stone at pipe outlets are,critical to reducing stormwater velocity and preventing scouring and erosion in the sensitive wetland buffers where they are located. Routine inception and maintenance are important to their long term functioning.The three are located as follows: To the left of the entry drive approximately 100 feet from Osgood Street and 70 feet off the drive. ➢ Southeast corner of side parking lot at Residential Building D, behind garage. > Southwest corner Residential Building D over retaining wall. ➢ Between Residential Buildings 0 and E over retaining wall. The aprons should be inspected four times per year. Remove any trash or debris that might inhibit flow, replace stones that may have moved, keep area free of vegetation.
