This permit shall be effective from the date of issuance until January 8, 2022, and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS 1. This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. 2. This stormwater system has been approved for the management of stormwater runoff as described in Section 1.7 of this permit. The stormwater control has been designed to handle the runoff from a total of 137,650 square feet of impervious area, which includes 67,083 sf of proposed BUA for Regional Comm Station (P-726); 8,712 sf of existing BUA; 13,939 sf of offsite BUA; 31,363 sf of proposed BUA for CH53K' Maintenance Bldg.

A 50' wide vegetative buffer must be provided and maintained adjacent surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and rivers and the mean high water line of tidal waters. 4. The orifice discharge from the wet detention pond must be directed into a 30-foot vegetated filter strip designed to pass the peak flow from the design storm in a diffuse, non -erosive manner. All runoff in excess of the design storm shall bypass the filter. The BMP will be limited to the treatment of that maximum amount of built -upon area indicated in Sections 1.2 and 1.7 of this permit, and per approved plans. The built -upon area for any future development is limited to 16,553 square feet. 6. The runoff from all built -upon area within the permitted drainage area of this project must be directed into the permitted stormwater control system.

The records will indicate the date, activity, name of person performing the work and what actions were taken. 5. Decorative spray fountains will not be allowed in the stormwater treatment system because the permanent pool volume is less than 30,000 cubic feet.

The new P-676 facility will be situated with its long axis orientated in an east -west direction and the short axis parallel to McAvoy Street. A new concrete apron and access drive will be provided from McAvoy Street to the south side of the new facility and extended to the north side of the existing AS255 building. A POV parking area with 108 vehicles will be constructed to the north of the P-676. The POV parking area will also include six motorcycle spaces, three visitor spaces and five accessible parking areas. The parking lot will have two entrances from the adjacent streets — one from Curtis Rd and one from McAvoy Street. Emergency vehicle access will be maintained at the site by extending the reinforced grass geocell system in front of P-726, along the north side of P-676, to McAvoy Street. The geocell system will be restrained by using a flush barrier curb system on both sides. The P-676 site will be developed with a post -developed impervious area that exceeds the pre - developed impervious area by only 6,099 SF.. The storm water management features provided as part of the P-726 will provide the required water quality from the P-676 site to meet the North Carolina Department of Environment and Natural Resources (NCDENR) requirements. The NCDENR Stormwater Management Permit for the P-726 project provided for water quality and quantity for 58,370 SF of the P-676 site to include 47,916 SF of impervious. The current design for P-676 calls for a total of 49,658 SF of the total site including-31,363:SF=of=impervious:going:to> the permitted forebay and detention pond. This 31,363 SF of impervious being treated more than compensates for the additional 6,099 SF increase between pre and post development. Bypass runoff from the northern parking lot and concrete apron have been designed such that the pre -development rate and volume to the existing northeast and southeast outfalls will not be exceeded in the post development design in accordance with Energy Independence and Security Act (EISA) Section 438 requirements. Low Impact Development (LID) strategies have been implemented throughout the site by minimizing the use of curbs, allowing storm water runoff to sheet flow onto grassed areas, installing a geocell system for emergency vehicles, and providing landscaped areas within the proposed parking lot. As discussed at our scoping meeting with NCDENR on Thursday August 14, 2014, we were advised to revise the existing storm water plans for the P-726 project to incorporate the new P-676 project. The revised permit plans, BUA calculations, application form and permit fees are attached herewith for review and approval. EROSION AND SEDIMENT CONTROL An Erosion and Sediment Control Plan has been prepared for the P-676 project. This plan along with the applicable application forms and review fees will be submitted concurrently with the Stormwater Management Permit Plan Revision to NCDNER for review and approval. `It`,,,%111111,/I/ .1 rA/ /.
