Subject: Notice of Intent for 99 Buck Island Road Infiltration Basins
This Notice of Intent (NOI) is to provide information on the proposed return of highly treated
wastewater effluent via infiltration basins at 99 Buck Island Road in the Town of Yarmouth. The
proposed project is part of the first Phase of the Town’s Comprehensive Wastewater Management Plan
(CWMP). This CWMP is designed to reduce nitrogen loads to estuaries and harbors which will improve
water quality by collection and centralized treatment of wastewater which current enters the aquifer
through septic systems. The proposed project may potentially have indirect impacts to wetland
resource areas by increasing groundwater levels. There will not be construction (i.e. direct impacts) in
the wetland resource areas or buffer zones as part of this proposed project.
Enclosed please find 1 hardcopy of the attachments listed below. Six additional copies of the NOI form,
Attachment 5 (Yarmouth WRRF Site Plan), Attachment 6a (Wetlands Monitoring Plan), Attachment 6b
(Groundwater and Surface Water Monitoring Plan) and Attachment 9b (Wetlands Areas Sheet R1
Highlighted Wetland Resource Area Delineation Mapping) are provided for the Commission’s review.
The Notice of Intent form and supporting documentation have been submitted electronically to
MassDEP through the eDEP filing site under transaction #1688398.
I look forward to speaking with the Conservation Commission about this project.
