Dear Mr. Owens,

The Division of Water Resources (DWR) received a letter dated July 28, 2016, from SEPI Engineering &
Construction (at the behest of the Town) regarding the 401 Water Quality Certification/CAMA Major
Permit application for Bailey & Associates (Grandview Marina) at 202 Summer Rest Road in Wilmington.
The letter provided an engineering review of the proposed marina project relating to what impact the
project could potentially pose to the Town's Northeast Interceptor (NEI) sanitary sewer force main that
lies beneath the Atlantic Intracoastal Waterway (AIWW). After reviewing the letter above, all other
information within our files, and communicating with the original contractor who installed this portion
of the NEI, there appears to be an inconsistency pertaining to the type of material the NEI is made of in
the area of the AIWW crossing. The letter above states that the pipe in this area is 14 -inch ductile iron
pipe (DIP) whereas other correspondence from past staff of the Town indicates that the pipe is 14 -inch
HDPE. Knowing the type of pipe the NEI is made of in this location will aid us in finishing our review
under Section 401 of the Clean Water Act. If you could furnish this information to us as soon as
possible, we would greatly appreciate your assistance. Please contact Chad Coburn at [phone] or
at [e-mail] if you have any questions.
Sincerely,
Ji egson, Regional Supervisor
