The plan submitted has been found acceptable with modification and subject to the following stipulations: 1. This is not a stormwater.discharge permit approval. If you receive comments from DENR concerning the slromwater permit, and the plans change, you. will have to make anew full submittal as stated in note P2. Provide a copy of approved stormwater plans and calculations along with a copy of the permit when issued. 2. Provide plans for final signature. PW will require 3 full size sets, 1 scaled -half size set, and a PDF copy of signed/sealed plans. 3. Indicate tree protection location on plans. 4. ,. Provide a note stating that the existing sewer service to be removed shall be coordinated with TOSP for . disruption and reconnection. S. Clarify fire line to be DIP with a dedicated utility easement. 6.: In order to ensure the early coordination and implementation of the erosion control for this project, it. is requested that.a pre -construction conference be held. Representatives of the owner, engineer, contractor, and this office should attend. Please notify Mn Barry Hinson at (910) 692-1983 when scheduling this conference. 7. At the pre -conference, the representative of this office will deliver a set of plans clearly marked as approved for erosion control .by the Town. After the installation of temporary erosion control measures and devices the representative of this office will issue the Town of Southern Pines Grading Permit. The Grading Permit must be posted on the job site. During all phases of construction, the contractor must work only from a set of approved plans. The marked set of plans and a copy of this letter most be on the site at the time of any construction activity. 8. The developer is responsible for obtaining any and all permits and approvals necessary for the development of this project prior to the commencement of this land -disturbing activity. This could include the Division of Environmental Management under storm water regulations, the US Army Corps of Engineers under Article 404 jurisdiction, local county or town agencies under their local ordinances, or others that may be required. This approval cannot supersede any other permit or approval; however; in the case of a Cease and Desist Order from the Corps of Engineers, that Order would only apply to wetland areas. All other lands must still be in compliance with the Sedimentation Pollution Control Act. 9. If any area.omsite falls under the jurisdiction of Section 404 of the 'Clean Water Act:, the developer is responsible to the orders of the US Army Corps of Engineers. Any erosion measures that fall within jurisdictional wetland areas must be relocated to the transition point between the wetlands and the highlands to assure that the migration of sediment will not occur. If that relocation presents a problem or contradicts any Phone: 910-692-1983 Fax: 910-692-1085 requirements of the Corps of Engineers, it is the responsibility of the developer to inform the Erosion Control Inspector so that an adequate contingency plan can be made to assure sufficient erosion control on -site. Failure to do so will be considered a violation of the approval. 10. This project is subject to the National Pollutant Discharge Elimination System (NPDES) and covered by the enclosed general storm permit NCGO10000 (Construction Activities). Should you have questions concerning this permit, contact Ms. Belinda Henson, Division of Environmental Management, at 910-433-3300. It. Any borrow material brought onto this site must be from a legally permitted mine site or other approved source. A single use borrow or waste area site is only permissible if it is operated under control of the financially responsible person or firm that is developing this site. An approved erosion and sediment control plan is required for all single use borrow and waste sites. 12, Following the installation of all initial erosion control measures, you should notify this office to request an inspection prior to proceeding with any grading. 13. Following completion of the project, you should notify this office to schedule a final inspection. The purpose of this inspection is to ensure that all erosion control requirements have been met. 14. This permit ie valid only for 8:e land uwner(s) and financially responsible person(s) as listed on the plans and Financial Responsibility/Ownership Form. Any changes must be reported to this office on an amended Financial Responsibility/Ownership form. 15. With this approval the construction inspector for the Town of Southern Pines or his agent has the right to enter the permitted property to provide for periodic inspection of the land -disturbing activity in accordance with North Carolina general statue 113a-61.1. 14. The approval of this plan, by the Town of South ern Pines, in no way is meant to relieve the design professional of his or her responsibility for the project design. This approval is subject to the satisfactory performance of the erosion control measures under field conditions. Should it be determined that the requirements of the Sedimentation Pollution Control Act of 1973 (G.S. I I3A, 51- 66) and the Soil Erosion and Sedimentation Control Ordinance of the Town of Southern Pines are not being met, revisions to the plan and its implementation will be required. This permit allows for a land disturbance, as called for on the application plan, not to exceed 3_6 acres and/or the construction limits as shown on the plans. Exceeding these limits will be a violation of this permit and would require a revised plan and additional application fee. Amendments to the plan should be submitted to this office under the same procedure as followed for the original plan. We look forward to working with you on this project.

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).

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, 1 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 be repaired immediately. BMP element: Potentialproblems: How I will remediate theproblem: The entire BMP Trash/debris is present. Remove the trash/debris.

Mulch is breaking down or has floated away. Soils and/or mulch are clogged with sediment. An annual soil test shows that pH has dropped or heavy metals have accumulated in the soil media. How I will remediate the problem: Regrade if necessary to route all flow to the pretreatment area. Restabilize the area after grading. Search for the source of the sediment and remedy the problem if possible. Remove the sediment and restabilize the pretreatment area. Provide additional erosion protection such as reinforced turf matting or riprap if needed to Remove the weeds, preferably by hand. Prune according to best professional practices. Determine the source of the problem: soils, hydrology, disease, etc. Remedy the problem and replace plants. Provide a one-time fertilizer application to establish the ground cover if a soil test indicates it is necessary. Remove tree stake/wires (which can kill the tree if not removed). Spot mulch if there are only random void areas. Replace whole mulch layer if necessary. Remove the remaining much and replace with triple shredded hard wood mulch at a maximum depth of three inches. Determine the extent of the clogging - remove and replace either just the top layers or the entire media as needed. Dispose of the spoil in an appropriate off -site location. Use triple shredded hard wood mulch at a maximum depth of three inches.
