Specific Permit Conditions:
1. Prior to the start of constrnction and issuance of a Building Permit, the applicant shall
record an executed Stormwater Operation, Maintenance, and Inspection Agreement that
is binding on all subsequent owners of land served by the private storrnwater
management facility by recording it in the land records of the Registry of Deeds. The
maintenance schedule and responsibility for maintenance of all components of the
proposed stom1water management system must be adequately specified in Attachment A
to this Agreement. The draft Stormwater Operations and Maintenance Manual that was
submitted as part of the Storm water Management Report referenced above can be used
for Attachment A but must be revised to include additional items including but not
limited to: 1) inspection and maintenance of the proposed stone trenches and 2) ongoing
inspection and maintenance throughout the site of erosion and concentration of flows in
rills and gullies that may result from the flow of stormwater off of the solar panels. This
agreement shall be approved by the Northampton DPW and signed by the owner and the
Mayor of Northampton. The Northampton Storm water Management Ordinance (Chapter
281) provides additional guidance for the requirements ofthis agreement.
2. This project will be required to submit a Notice of Intent (NOI) to the U.S. EPA for
coverage under the NPDES Stormwater Construction General Permit. A copy of the final
NOT and Stormwater Pollution Prevention Plan (SWPPP) shall be submitted to the
Northampton DPW for approval prior to the start of construction and prior to issuance of
a building permit for each phase of construction.
3. Prior to the start of construction and prior to issuance of a building permit, construction
plans shall be submitted to the DPW for approval.
4. The proposed project and stormwater management system is designed to mitigate peak
storm water flows and discharge clean storrnwater. n: after construction of the proposed
system, the system is found to increase storrnwater flows or result in the discharge of
sediment or other pollutants to adjacent properties, to resource areas or to municipal
roadways and drainage systems, the owner shall redesign and reconstruct the drainage
system to prevent increased storm water flows and the discharge of pollutants.
