Dear Mr. Thompson and Mr. Nason:

This letter is in response to the application you submitted to the U.S. Army Corps of Engineers (USACE), New England District on June 9, 2025, for a Department of the Army general permit verification. We have assigned this project file number NAE-2025- 01420, which you should reference in all correspondence with this office.

Proposed work includes the permanent discharge of fill material within 423 square feet below the Ordinary High Water (OHW) mark of two unnamed intermittent streams and within 2,688 square feet of wetlands associated with the removal of an existing 30” corrugated metal pipe (CMP), replacement of an existing 30” CMP with a new 48” reinforced concrete arch pipe (RCP), extension of an existing 36” RCP, roadway reconstruction, construction of a shared use path, and installation of rip-rap scour protection. The work also includes the temporary discharge of fill within 482 square feet below the OHW mark of two unnamed intermittent streams and within 14 square feet of wetlands associated with temporary construction access and temporary erosion controls along Ayer Road and Gebo Lane in Harvard, Massachusetts. The work is shown on the enclosed plans titled “MASSACHUSETTS DEPARTMENT OF TRANSPORATION
