Dear Mr Marshall
Effective August 1, 2013 the Post -Construction Stormwater Management Program has been transferred from the
Division of Water Quality ("DWQ") to the Division of Energy, Mineral and Land Resources ("DEMLR") All
previous references to DWQ will remain in older permits issued prior to August 1, 2013 until they are modified
Please note that this permit will now reference DEMLR as the Division responsible for enforcement of the permit
On August 5, 2009, the Governor signed Session Law 2009-406 This law impacted any development approval
issued by the former Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which
was current and valid at any point between January 1, 2008, and December 31, 2010 The law extended the
effective period of any permit that was set to expire during this time frame to three (3) years from its current
expiration date On August 2, 2010, the Governor signed Session Law 2010-177 which granted an extra year for
a total of four (4) years extension
The Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for
the subject permit on January 18, 2022 The Division is hereby notifying you that permit SW8060311 has been

Important maintenance procedures
- Immediately after the wet detention basin is established, the plants on the

needed, until the plants become established (commonly six weeks)
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin
- If the basin must be drained for an emergency or to perform maintenance the
flushing of sediment through the emergency drain should be mitumized to the
maximum extent practical
- Once a year, a dam safety expert should inspect the embankment
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 10 inches (or 15 inches if in a
Coastal County) Records of operation and maintenance should be kept in a known set

Project is a lot with a maximum allowed BUA of 5 000 sq ft that drains to class SC waters
Project proposes a 1 000 sq ft permeable concrete driveway with a 6 gravel base
Managed grass factor = 0 6
1000 x 0 6 = 600 square feet is counted as managed grass
1000 600 = 400 square feet is counted as built upon area
5000 400 = 4 600 square feet available for house and other BUA
Example #2
Project is a high density commercial site with a 5 000 square foot parking lot
Project is within 1/2 mile of and draining to SA waters An infiltration system is proposed
The parking lot will handle <100 cars per day and is a flexible pavement with a 4 gravel base
Managed grass factor is one half of 0 4 = 0 2
5000 x 0 2 = 1000 square feet is counted as managed grass
5000 1000 = 4 000 square is counted as impervious
The total BUA used to calculate the minimum volume draining to the
infiltration system can be reduced by 1 000 square feet
