The work associated with this Order(the "Project ") is (1) ❑ is not (2) O subject to the Massachusetts Stormwater Standards. If the work is subject to Stormwater Standards, then the project is subject to the following conditions; a) All work, including site preparation, land disturbance, construction and redevelopment, shall be implemented in accordance with the construction period pollution prevention and erosion and sedimentation control plan and, if applicable, the Stormwater Pollution Prevention Plan required by the National Pollutant Discharge Elimination System Construction General Page 5 of 9 * ELECTRONIC COPY Massachusetts Department of Environmental Protection Bureau of Resource Protection - Wetlands WPA Form 5 - Order of Conditions Massachusetts Wetlands Protection Act M.G.L. c. 131, §40 Provided by MassDEP: MassDEP File #:246 -0673 eDEP Transaction #:605234 City/Town:NORTHAMPTON Permit as required by Stonnwater Standard 8. Construction period erosion, sedimentation and pollution control measures and best management practices (BMPs) shall remain in place until the site is fully stabilized b) No stormwater runoff may be discharged to the post - construction stonnwater BMPs unless and until a Registered Professional Engineer provides a Certification that: i. all construction period BMPs have been removed or will be removed by a date certain specified in the Certification. For any construction period BMPs intended to be converted to post construction operation for stormwater attenuation, recharge, and/or treatment, the conversion is allowed by the MassDEP Stormwater Handbook BMP specifications and that the BMP has been properly cleaned or prepared for post construction operation, including removal of all construction period sediment trapped in inlet and outlet control structures; u.. as -built final construction BMP plans are included, signed and stamped by a Registered Professional Engineer, certifying the site is fully stabilized; iii any illicit discharges to the stormwater management system have been removed, as per the requirements of Stormwater Standard 10; iv. all post - construction stonnwater BMPs are installed in accordance with the plans (including all planting plans) approved by the issuing authority, and have been inspected to ensure that they are not damaged and that they are in proper working condition; v. any vegetation associated with post - construction BMPs is suitably established to withstand erosion. c) The landowner is responsible for BMP maintenance until the issuing authority is notified that another party has legally assumed responsibility for BMP maintenance. Prior to requesting a Certificate of Compliance, or Partial Certificate of Compliance, the responsible party (defined in General Condition 19(e)) shall execute and submit to the issuing authority an Operation and Maintenance Compliance Statement ( "O &M Statement ") for the Stormwater BMPs identifying the party responsible for implementing the stonnwater BMP Operation and Maintenance Plan ( "O &M Plan") and certifying the following: i.) the O &M Plan is complete and will be implemented upon receipt of the Certificate of Compliance, and ii.) the future responsible parties shall be notified in writing of their ongoing legal responsibility to operate and maintain the stormwater management BMPs and implement the Stormwater Pollution Prevention Plan. d) Post - construction pollution prevention and source control shall be implemented in accordance with the long -tetra pollution prevention plan section of the approved Stormwater Report and, if applicable, the Stonnwater Pollution Prevention Plan required by the National Pollutant Discharge Elimination System Multi- Sector General Permit. e) Unless and until another party accepts responsibility, the landowner, or owner of any drainage easement, assumes responsibility for maintaining each BMP. To overcome this presumption, the landowner of the property must submit to the issuing authority a legally binding agreement of record, acceptable to the issuing authority, evidencing that another entity has accepted responsibility for maintaining the BMP, and that the proposed responsible party shall be treated as a permittee for purposes of implementing the requirements of Conditions 190) through 190c) with respect to that BMP. Any failure of the proposed responsible party to implement the requirements of Conditions 190) through 19(k) with respect to that BMP shall be a violation of the Order of Conditions or Certificate of Compliance. In the case of stormwater BMPs that are serving more than one lot, the legally binding agreement shall also identify the lots that will be serviced by the stormwater BMPs. A plan and easement deed that grants the responsible party access to perform the required operation and maintenance must be submitted along with the legally binding agreement 1) The responsible party shall operate and maintain all stormwater BMPs in accordance with the design plans, the O &M Plan, and the requirements of the Massachusetts Stormwater Handbook. g) The responsible party shall: 1.

Make the maintenance log available to MassDEP and the Conservation Commission ( "Commission") upon request; and 3. Allow members and agents of the MassDEP and the Commission to enter and inspect the site to evaluate and ensure that the responsible party is in compliance with the requirements for each BMP established in the O &M Plan approved by the issuing authority. h) All sediment or other contaminants removed from stormwater BMPs shall be disposed of in accordance with all applicable federal, state, and local laws and regulations. Illicit discharges to the stormwater management system as defined in 310 CMR 10.04 are prohibited.
