Raleigh Regional Office
The Division of Energy, Mineral, and Land Resources (DELMR), received a complete Stormwater
Management Permit Application for the subject project on October 12, 2017. Staff review of the plans

Regulations set forth in Title 15A NCAC 2H.1000 rules. We are forwarding Permit No. SW5171002, for
the construction, operation and maintenance of the subject project and the stormwater system. This permit
shall be effective from the date of issuance and shall be subject to the conditions and limitations as
specified therein, and does not supersede any other agency permit that may be required.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings

become established (commonly six weeks).
- Snow, mulch or any other material will NEVER be piled on the surface of the bioretention cell.
- Wheeled or tracked equipment will NEVER be driven over the bioretention planting surface.
- Special care will be taken to prevent sediment from entering the bioretention cell.
- If standing water is present 2 days after rainfall, conduct an infiltration test of the soil media.
After the bioretention cell is established, inspect it quarterly. Inspection activities shall be performed as follows and maintenance activites shall
commence immediately to remediate any problems observed per the table below.
