These sources of impacts and ananageincnt thereof (1-nore fully explained below) have been, to date, governed by a series of Erdorcemerit Orders, The Cornini ssian is of the opinion that the sources and nature of impacts are now sufficiently characterized, so that the means and methods of their long--term manageinent/treatment are better understoad. The NACC finds that this body ,of knowledge serves to better inform the public whir additional conditions that have been incorporated into the Amended Order, which will result in a comprehensive, recordable, regulatory document.

COSTS The estimated annual cost for the operation and maintenance is $80500*00. 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 nonstructural 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 resit in measureable stormwater quality, volume and velocity controls. Ultimately, the m onitoring and successful operations of all permanent stormwater measures, shall be the Property Manager's 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 and proper insurances, as applicable.

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 followi ng: ➢ The left side of the entry drive from Osgood Street to the Princeton leasing office. )Po- Behind the fool 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 wail in the rear parking dot of Residential Building E The wetland resources and Wrisdictlonal 100 foot buffer pones 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 and 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 lire surface flow into deep sum catch basins with owlet hoods. The project- s main stormwater practices are underground storage systems, using the "Stormtech" proprietary chamber system and Rainstore 3 . Each of the Stormtech system contains isolator rows with an inlet control manholes that are also connected to the Rainstore 3 chambers. Collectively, the chosen stormwater systems will meet or exceed local, state and federal standards as designed, when operated, monitored and maintained properly. ------------- ...... .......

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 fiimes per year for sediment levels. Each of the thirty-three (39) 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 agas/oil hoods but the constant water level in the catch basin generally indicates this elevation . A gape measure can be used to measure the depth from the rim grate to the water level, then the depth of the wader can be measured and compared to the four feet. The distance sham of four feet equals the sediment level, Catch basins must be pumped when the sediment level exceeds one ( 1) fort through the use of a vacuum extractor or once every year. Disposal of the accumulated sediment and hydrocarbons must be in ' accordance with applicable local, stake, and federal guidelines and regulations. Area drains ( 10 Total} ' The area drains should also be maintained similar -to the Deep sump hooded catchbasins above. STaRMTECH I.SOLATOR ROW ( 13 TOTAL) Routine inspection schedule reeds 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 flay a critical role in determining the actual frequency of inspection and maintenance practices, At a minimum the StormTech system 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 precious observation of sediment' deposition , Thy I solato r Row incorporates a combination of standard manhole(s) and strategically located inspection ports (as needed ). The inspection parts allow for easy access to the system from the surface, eliminating the need to perform a confined space entry for inspection purposes. If upon visual inspection it is found that sediment has accumulated, a stadia rod should be inserted to determine the depth of sediment. When the average depth of sediment exceeds 3 inches throughout the length of the Isolator Row, clean-out should be performed, The Isolator Row was designed to reduce the cost of penodic maintenance. By "isolating" sediments to jest one row, casts are dramatically reduced by eliminating the need to clean out each raw of the entire storage bed . If inspection indicates the potential need for maintenance, access is provided via a manhole(s) located an the end(s) of the row for cleanout. If entry into the manhole is required, please follow local and OSHA rules for a confined space entries. 5tormwater operations and Maintenance Plan � � 6 1 P a g e i HANCO.CK I-hi toy at North Andover Ali�� Inie �t Homes 1210 Osgood St, Noi-th Andover Loiig Terin Storinwater Operaflojis & Mabiteitance Plait Revised1 -1 -1 ��+r+,•,• r•,�+vr�y�. �....,w,�::•:'•r:'t r,'f•.;� ,v•,i:v.'' �'•}'.+:;:;^.,'•"i f,.y.++r.,,,..••::'::x+ 1 ,7 ,f Sr+,rf4":+ ,:?.': rS'lM1i.r'i::i r',r r�. :++"„'''�+'.f.� fl; ?�.'
