Subject: Additional Information - Mill Pond Sewer Line - DWR 15 -0392
The Division of Water Resources (DWR) has performed a review of the 401 Water Quality Certification application
submitted for the referenced project. Please provide additional information so we can complete our review.
The Stream Crossing Detail provided on Figure 3.1 shows Class B Rip Rap from the typical high water depth to a
minimum of 6- inches below the stream bed. The DWR considers this a permanent impact. Please update the
impact tables on page 5 of the Pre - Construction Notification (PCN) form to reflect the proposed permanent
impacts. Alternatively, please update the Stream Crossing Detail to illustrate a temporary impact (e.g., remove
rip rap below the ordinary high water mark). Feel free to contact me for clarification on temporary and
permanent impacts.
Several of the listed stream impacts appear to occur under existing culverts as illustrated on the included impact
maps. Please clarify if the proposed sewer line will be installed under existing culverts and if the impact lengths
can be minimized.
Please provide this additional information by June 18, 2015.

Zan Price, P.E.
