If a spill occurs that directs contaminants to the catch basin entry points on site. Those spills shall be contained by closing the flap gates at the outfalls. Training of staff involved with implementing the Long-Term Pollution Prevention Plan is detailed below. List of Emergency contacts responsible for implementing the Long-Term Pollution Prevention Plan are listed above in the Basic Information section. Several types of structural and non-structural water quality controls in various combinations are proposed to treat stormwater generated on the site. These measures include grass channels and bioretention areas. These water quality treatment measures will result in the removal of total suspended solids (TSS) load in runoff prior to discharge from the site, consistent with DEP's TSS removal standard to the maximum extent practical. The following best management practices are specified in the proposed development program to mitigate the increase in stormwater runoff from the site. BMPs Used ➢ Grass Channels ➢ Bioretention Areas Post-Development Activities 1. The Grass Channels shall be mowed as needed during the growing season so that the grass height does not exceed 6 inches. 2. The Grass Channels shall be inspected semi-annually the first year and at least once a year thereafter. The grass shall be inspected for growth and the sides for signs of erosion. 3. The Grass Channel shall be replanted with an alternative grass species approved by the planning board if the original grass cover is not successfully established. 4. If the Grass Channels grass is impaired by winter road salt or other deicer use, re- establish the grass in the spring. 5. Remove trash and debris from Grass Channels prior to mowing. 6. Check Grass Channels for sediment build up on the yearly basis. Remove sediment with hand tools when sediment build up reduces the channel's capacity. 7. Inspect soils and repair eroded areas of Bioretention Area annually. Re-mulch voids as needed. 8. Remove litter and debris from Bioretention Area annually. 9. Treat diseased vegetation in Bioretention Area as needed. 10. Remove dead vegetation from Bioretention Area twice a year (spring and fall). 11. Re-mulch Bioretention Area every two years. 12. Remove invasive species from Bioretention Area annually (spring). 13. Prune Bioretention Area twice a year(spring and fall). 14. If Bioretention Area fails excavate Bioretention Area scarify bottom and sides, replace filter fabric and soil, replant, and mulch. 15. Never store snow in Bioretention Area. 16. All sediments removed from the site drainage facilities shall be disposed of properly and in accordance with all applicable local and state regulations. 17. All vegetated slope areas on the site shall be stabilized following completion of construction and maintained to control erosion. Any disturbed areas shall be re-seeded and stabilized by the application of jute mesh if the slope exceeds 3 feet horizontal to 1 foot vertical. 18. Salt or deicing materials such as calcium chloride, calcium magnesium acetate (CMA), magnesium chloride or approved equivalent may be used on for de-icing on the paved parking and driveway areas and walkways during the winter months in the minimum amount necessary to maintain public safety. No sodium chloride is permitted for de- icing. All structural BMP's and maintenance responsibilities as identified on the site plans and within this document will be owned and maintained by the owner of the property and shall run with the title of the property. Annual Reporting Form The Owner shall keep complete records of all BMP maintenance activities using the following form. Parties responsible for the operation and maintenance of a stormwater management facility shall provide records of all maintenance and repairs to the Planning Board upon request. Parties responsible for the operation and maintenance of a stormwater management facility shall make records of the installation and of all maintenance and repairs, and shall retain the records for at least five (5) years. These records shall be made available to the Planning Board during inspection of the facility and at other reasonable times upon request. If a responsible person fails or refuses to meet the requirements of the O&M Plan, the Planning Board, after thirty (30) days written notice (except, that in the event the violation constitutes an immediate danger to public health or public safety, 24 hours notice shall be sufficient), may correct a violation of the design standards or maintenance requirements by performing the necessary work to place the facility or practice in proper working condition. The Planning Board may assess the owner of the facility for the cost of repair work, which shall be a lien on the property. # CD � § � � 0 � ) /ƒ § _ CL -0 Zr- aaa k $ » 02 = � Eq $ ® 0E k§ � o E f t � > _ $ f7 f@ = 77 ƒ ) \7 ( k ƒ § � § f � > > § & § S2 \/ f / t � � } k } > E k k U) k /\ 0 2 2 . � / k m $ � \ ƒ . cc 0 m S 2 E § d ..

Plan of BMP's Reference is made to the Proposed Site Plans for the location of all BMP's. Post-Construction Snow Storage No snow will be stored on site. Maintenance of Natural Turf Fields The Maintenance of Natural Turf Fields (MNTF) contains a program of maintenance practices to be used on this site. This program is designed to serve as the maintenance blueprint and describe materials used, rates of application and where possible, and expected time of application. Fertilizing: Low Fertilizer Lawn Seed Mix (Earth Turf) has been specified for turf fields on the site. The seed mix uses MicroClover, a nitrogen fixing plant, to reduce the need for fertilizer application and maintenance. It is also designed to be drought tolerant and have a fast establishment time. Shade mixes of Earth Turf are also available for shady areas. Soil testing will be performed before establishment of the turf to determine soil amendment needs and to avoid unnecessary fertilization. The grow-in period often lasts up to 2 seasons and will require higher than normal annual inputs of fertilizers and limited use of pest control materials in order to promote rapid establishment of cover which reduces soil erosion and minimizes the likelihood of weed infestation. Fertilizer applied to establish the turf should be slow release or Water Insoluble Nitrogen. After establishment of the turf, the soil should be tested every 3-5 years for pH and nutrient levels, and only the recommended soil amendments applied. Applications should not be done in spring, when there is generally a high water table, or before heavy rainfalls. Fertilization should be minimized on slopes to limit runoff. Fertilizer and other soil amendments shall be stored in dry areas in their original containers. Fertilizers, if used, will be "phosphorous free". Mowinq: Lawns will be mowed at a height of three (3) inches during the active growing season. Longer grass helps shade the soil and gather moisture, while competing more effectively with weeds. Mowing frequency will vary with the growing season and should be set by the plant height and not a set date. It will often be necessary to mow twice a week during periods of surge growth to help maintain plant health and color. Mowing should be less frequent during periods of heat and drought. The basic rule of thumb is to never remove more than 1/3 of the grass blade in one mowing. Removing more than half of the grass blade at a time can put the plant into shock, thus making it more susceptible to stress, disease and pests. A sharp mower blade is also key for clean cuts that heal quickly, versus a worn blade that invites disease and looks unsightly. A final mowing in November should be at two (2) inches to avoid matting and over wintering diseases. Clipping Management: Clippings from all lawn areas will be left in place. Heavily clumped grass clippings are an indication of infrequent mowing, calling for an adjustment in the schedule. Heavy clumps must be raked in and dispersed by hand. Take care with the direction of mower machine movement - do not blow clippings into mulch beds and alternate patterns to assure an even cut and avoid soil compaction. Irrigation Management: The modem computer-controlled irrigation systems used on today's sites are very flexible to be able to irrigate to the amount needed for adequate plant growth while not over irrigating. Over-irrigation will make many disease problems more severe, can lead to a significantly greater likelihood for either pesticide or nitrate contamination, and can waste upwards of 50 % more water than is actually needed. Care must be made to prevent over-irrigation for both water conservation and maintaining a healthy lawn. Preparing turf for hot, dry summer weather requires that over-irrigation be avoided during the spring. Maintaining the root zone in a wet or saturated condition inhibits the establishment of a deep, fibrous root system during the spring, making summer survival more difficult. Recommended steps include: 1. Apply water as uniformly as possible (variable soil conditions and plant needs will require customized application in some instances). 2. Apply water only as fast as the soil can accept it. To avoid runoff, use short, repeated cycles or cultivate the soil (core, slice, spike) to improve infiltration. Irrigate when there is little wind and avoid mid-day irrigation during peak evaporation periods. 3. Use drip irrigation for tree and shrub areas with operational indicators. 4. A well-designed, correctly installed, properly utilized, automatic irrigation system provides the best means of conserving water. The irrigation system should be operating at peak efficiency and maintained thoroughly. Topdressing: Topdressing is a practice of adding a small amount of sterile compost to the surface of the turf to reduce the development of thatch. Fine lawns will be topdressed annually with an approved source of composted organic matter, or as needed based on the turfgrass growth rate. Integrated Pest Management: The basic goal and philosophy of the Integrated Pest Management (IPM) program is to produce a healthy, pest resistant lawn that will have little or no impact on the surrounding environment. Every available pest management practice will be utilized with the goal of using pesticides as a last resort after all other control options have been followed.A new site provides the opportunity to construct a system that is less prone to stress, which is often the main cause of pest damage or invasion of weedy species. The components of this IPM plan as established for New England sites are: proper grass selection, developing the site specific pest knowledge base, using action thresholds, soil, plant tissue and water testing, pest management options (cultural, biological and pesticidal) and yearly evaluation on the effectiveness of program and modification of plan. It is anticipated that, after the first year of establishment of this site, weed problems will tend to be minimal. This is a result of sound site practices that will produce a dense, competitive environment against weed encroachment. Thus, the anticipated weeds on this site will be limited to broad leaf weeds and crabgrass, and less frequently moss. Weed control measures will be minimized to prevent runoff to the river area. Inspections Training Training sessions must be provided by the Owner for property managers and operations personnel. The Training Log shall be kept up to date by the Owner. Updating the Operation and Maintenance Plan This Operations and Maintenance Plan must be modified as necessary to: • Include additional or modified BMPs that correct problems identified as a result of an inspection. Revisions must be completed with seven (7) calendar days following the inspection. • Ensure the effectiveness of the Manual in eliminating or significantly minimizing pollutants from stormwater and flood waters discharging from the site. • Prevent the reoccurrence of release of a hazardous material or oil. • Address a change in design, construction, operation, or maintenance which has or may have a significant effect on the potential for the discharge of pollutants. The owner of the stormwater management system must notify the Planning Board or its Agent of changes in ownership or assignment of financial responsibility. The maintenance schedule in the O&M Plan may be amended to achieve the purposes of this Stormwater Management and Erosion Control Bylaw and Regulations by mutual agreement of the Planning Board and the Responsible Parties. Amendments must be in writing and signed by all Responsible Parties. Responsible Parties shall include owner(s), persons with financial responsibility, and persons with operational responsibility.
