Dear Mr. Smith:
Stormwater Permit No. SW7051002
Industry Ready Building, Lot 4
High Density Stormwater Project
Beaufort County
The Washington Regional Office received your request for a Name/Ownership
change for the subject project on October 1, 2012. An inspection conducted by Bill Moore
on November 19, 2012 revealed that the stormwater systems are constructed and working
properly, with only a few minor maintenance issues noted. An engineer's certification was
submitted on December 19, 2012 by Mr. Sam Jarvis indicating that the stormwater system is
built substantially according to approved plans. Based on our review of your
project/request, we are forwarding Permit No. SW7051002 dated December 20, 2012 to
X.S. Smith, Inc.
This permit shall be effective from the date of issuance until December 20, 2020 and
shall be subject to the conditions and limitations as specified therein. Please pay special
attention to"the Operation and Maintenance requirements in this permit. Failure to establish
an adequate system for operation and maintenance of the stormwater management system
will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable,
you have the right to request an adjudicatory hearing upon written request within thirty (30)
days following receipt of this permit. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless
such demands are made this permit shall be final and binding.

Infiltration Trench Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area of the infiltration trench will be carefully managed to reduce
the sediment load to the sand filter.
— The water level in the monitoring wells will be recorded once a month and after
every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
The infiltration trench will be inspected once a quarter and within 24 hours after every
storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of
operation and maintenance will be kept in a known set location and will be available
upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
