the materials and construction of the stormwater management system was constructed in

in the Commonwealth of Massachusetts and approved by the DPW prior to submission of
the certification statement described above.

Construction is defined as clearing, grading, excavation, filling, and installation of

Specific Permit Conditions:
1. Prior to issuance of a Building Permit or start of construction, the applicant or property
owner(s) shall record an executed Stormwater Operation, Maintenance, and Inspection
Agreement that is binding on all subsequent owners of land served by the private
stormwater management facility by recording it in the land records of the Registry of
Deeds. The maintenance schedule and responsibility for maintenance of the proposed
stormwater management system must be adequately specified in Attachment A to this
Agreement. This agreement shall be approved by the Northampton DPW and signed by
the owner and the Mayor of Northampton. Section 22-85 of the Northampton Stormwater
Management Ordinance provides additional guidance for the requirements of this
agreement.
2. This project may be required to submit one or more Notice of Intent (NOi) to the U.S.
EPA for coverage under the NPDES Stormwater Construction General Permit. A copy of

the final NOi and Stonnwater 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 pennit.
3. The proposed stonnwater drainage system in the area of the proposed cell tower
compound shall be completed in accordance with sheet Z-1 which specifies a 3 '6" Wide
by 2' Deep Infiltration Trench outside of the southwestern and a portion of the
southeastern fence line.
4. Prior to the start of construction test pits shall be conducted by a Certified Soil Evaluator
or Certified Professional Soil Scientist in the area of the proposed infiltration trenches A
and B to confirm at least a two foot separation between the seasonal high ground water
and the bottom of the proposed trenches. Test Pit logs shall be submitted to the DPW for
approval.
5. The proposed stonnwater management system is designed to mitigate peak stonnwater
flows. If, after construction of the proposed system, the system is found to increase
stonnwater flows to Haydenville Road or to adjacent properties, or cause increased
erosion, the owner shall redesign and reconstruct the drainage system to prevent any
increased and/or erosive stonnwater flows.
6. Prior to construction, the applicant must secure all necessary pennits and approvals from
the Massachusetts Highway Department for construction work in the State Highway
System layout and proposed stonnwater discharges to the stonnwater system owned and
operated by the Commonwealth of Massachusetts.
7. All stonnwater systems shall be installed as proposed and stabilized prior to receiving
