Subject: Permit No. SW7061128
ABHW Concrete
High Density Stormwater Project
Beaufort County
The Washington Regional Office received a completed Stormwater Application for the subject
project on January 9, 2007. Staff review of the plans and specifications has determined that the project, as
proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are
forwarding Permit No. SW7061128 dated July 26, 2011 for a wet detention pond to serve the ABHW
Concrete facility located at 347 South Wharton Station Road in Washington, NC.
This permit shall be effective from the date of issuance until March 20, 2017 shall void permit
SW7061128 issued on March 20, 2007 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. The issuance of this permit does not resolve any previous violations
of the stormwater rules for construction without a permit.
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, 6714 Mail Service Center,
Raleigh, NC 27699-6714. Unless such demands are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact
Samir Dumpor or me at [phone]. 1 1

When using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
actual impervious i % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal,. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the met detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed.
Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 7517o of the original design depth (see diagram below). Removed sediment shall be disposed
of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a wet detention basin or stream, etc,).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 3'O ltzr,
-il=� feet in the main pond, the sediment shall be removed.
