The Stormwater Permitting Unit received a complete Stormwater Management Permit
Application for Byrd Professional Building on March 25, 2010; with additional information
received on March 30, 2010 and April 13, 2010. Staff review of the plans and specifications'has
determined that the project, as proposed, will comply with the Stormwater Regulations set forth
in-l"itle 15A NCAC 2H.1000 and Session Law 2006-246. We are forwarding Permit No.
SW5100301, dated April 14, 2010, for the construction, operation and maintenance of the
subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until April 14, 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 inspection 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

protective covenants forms can be downloaded from
httpJ/h2o.enr.state.nc.us/su/bmp forms.htin #deed restrictions. Download the Iatest versions for each submittal.

protective covenants for this project, if required, shall include all the items required in the permit and listed
on the forms available on the website, that the covenants will be binding on all parties and persons claiming
under them, that they will run with the land, that the reg6ired covenants cannot be changed or deleted
without concurrence from the NC DWQ, and that they will be recorded prior to the sale of any lot.

Bioretention Operation and Maintenance Agreement
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 operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
-- Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month 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
