Omissions PART V DEFINITIONS Permit No. NCG010000 PART I - NCGO1 PERMIT COVERAGE This permit applies to all owners or operators of stormwater discharges associated with construction activities such as clearing, grading, and excavation, that result in the disturbance of a land area greater than or equal to one acre, or that are part of a common plan of development of that size or greater that are also subject to the North Carolina Sedimentation Pollution Control Act of 1973 (SPCA). This permit may also be issued to stormwater discharges from like activities deemed by the Division of Energy, Mineral, and Land Resources (DEMLR) to be similar to these operations in process or stormwater discharges. This permit shall not apply to land -disturbing activities that are covered under the NCG020000 (Mining Activities) permit or the NCG120000 (Landfills) permit. The SPCA requires that the persons engaged in subject construction activities develop and adhere to an Erosion and Sedimentation Control (E&SC) Plan. The Sedimentation Control Commission and DEMLR have created and adopted a North Carolina Erosion and Sediment Control Planning and Design Manual describing recommended sedimentation control techniques for construction activities. A person seeking coverage under this permit shall take the following steps in the following order: 1. Develop an E&SC plan that adheres to the SWPPP requirements of this permit, the SPCA and 15A NCAC 048 .0101-.0132. The North Carolina Erosion and Sediment Control Planning and Design Manual shall be used as guidance in meeting the applicable requirements. 2. Obtain approval of the E&SC plan by either DEMLR or the appropriate state delegated local entity (hereafter known as the "E&SC plan authority"). 3. Submit an electronic Notice of Intent (e-NOI) to DEMLR with documentation of the E&SC plan approval scanned and uploaded. The e-NOI is available at https:lldeq.nc.gov/NCGO1. In addition, pay the general annual permit fee provided for in § 143-215.31). DEMLR shall email the COC within three business days (or 24 business hours for a project being reviewed under DEMLR's Express review program) after the submittal of a complete and correct a-NOI and the receipt of the general permitting fee. 4. Commence the construction activity after receipt of the COC. S. Abide by the conditions of both the NCGO1 permit and the E&SC plan until completion of the construction activity and establishment of permanent ground stabilization. 6. Contact the E&SC plan authority after construction is complete and the site is permanently stabilized, contact the E&SC plan authority for the final/close out inspection of the E&SC plan. 7. Submit an electronic Notice of Termination (e-NOT) with a scan of the close-out inspection report uploaded. The e-NOT is available at https://de-q.nc.gov/NCG01. DEMLR shall email confirmation of the close-out of the COC within three business days after the submittal of a complete and correct e-NOT. The discharges allowed by this General Permit shall not cause or contribute to violations of North Carolina Water Quality Standards for surface waters and wetlands (15A NCAC O213.0200). Discharges allowed by this permit must meet all applicable water quality certification or permit requirements as outlined in 15A NCAC 02H .0500 and 02H .1300. This permit does not relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree. This General Permit does not cover any other point source discharge to surface waters of the state, nor does it cover activities or discharges that are covered by an individual NPDES permit. Any owner or operator of a subject construction activity not wishing to be covered or limited by this General Permit may apply for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 02H .0100, stating the reasons supporting the request. Any application for an individual permit Page 1 of 26 Permit No. NCG010000 should be made at least 180 days prior to the time the permit is needed unless waived by the Director (see Part IV Section B of this permit).

SECTION C. ADDITIONAL DESIGN AND CONSTRUCTION STANDARDS IN HIGH QUALITY WATER (HQW) ZONES 1. Extent of the HQW Zone HQW Zones are those areas in the 20 Coastal Counties that are within 575 feet of High Quality Waters and for the remainder of the state, areas that are within one mile of and drain to HQWs. 2. Disturbed Area Limits in HQW Zones Disturbed areas in HQW zones shall be limited at any time to a maximum total area within the boundaries of the tract of 20 acres. Only the portion of the construction activity within a HQW zone shall be subject to the 20-acre limit. Larger disturbed areas may be allowed with the written approval of the Director upon providing adequate engineering justification with a specific construction sequence that addresses phasing, limited exposure, weekly submitted self -inspection reports and/or more conservative design than the 25-year storm. The Director may also include other conditions as necessary based on specific site conditions. 3. Additional Sediment Basin Requirements in HQW Zones Sediment basins that discharge to HQW Zones shall be designed and constructed to meet the following criteria unless the permittee demonstrates to the E&SC plan authority that meeting each of the basin design conditions below would result in design or operational hardships. Alternative control measures, such as quicker application of ground cover or use of sediment flocculants, shall be allowed as a substitute on a case -by -case basis if it can be shown that use of the alternate practices is expected to result in an equal or better sediment discharge reduction from the site. (a) Use a surface withdrawal mechanism except when the basin drainage area is less than 1.0 acre. (b) Have a minimum of 1800 cubic feet per of storage area per acre of disturbed area. (c) Have a minimum surface area of 325 square feet per cfs for the peak flow from the 25-year storm. (d) Have a minimum dewatering time of48 hours. (e) Incorporate three baffles unless the basin is less than 20 feet in length, in which case two baffles are sufficient. 4. Open Channels in HQW Zones Newly constructed open channels in HQW zones shall be designed and constructed with side slopes DO steeper than two horizontal to one vertical if a vegetative cover is used for stabilization unless soil conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices, structural devices or other acceptable ditch liners. The angle for side slopes shall be sufficient to restrain accelerated erosion. Page 6 of 26 Permit No. NC6010000 SECTION D: CONSTRUCTION ACTIVITY BUFFERS The requirements in Section D below shall not apply to a land -disturbing activity in connection with the construction of facilities to be located on, over, or under a lake or natural watercourse (NCGS 113A-57). 1. Buffers in Non -Trout Waters Unless wider buffers are required per NC rules or statutes, the width of the buffer shall be sufficient to confine visible sedimentation to the 25 percent of the strip closest to the land -disturbing activity. The width of a buffer adjacent to a non -trout water shall be measured from the edge of the water to the nearest edge of the disturbed area. Recommended buffer widths to achieve this standard are shown in Table 2 below. Table 2: Recommended Buffer Widths Slope of Suffer (a/o} Recommended Width of Undisturbed Vegetation Adjacent to Non -Trout Waters 0-1 15 feet 1-3 20 feet 3-5 25 feet >5 25 feet + (% of slope - 5) 2. Buffers in Trout Waters Unless wider buffers are required per NC rules or statutes, the minimum width for an undisturbed buffer adjacent to trout waters shall be 25 feet. The width of a buffer adjacent to a trout water shall be measured horizontally from the top of bank to the nearest edge of the land -disturbing activity. However, the Sedimentation Control Commission may approve plans that include land -disturbing activity along trout waters when the duration of said disturbance would be temporary and the extent of said disturbance would be minimal. (NCGS 113A-57(1)). SECTION E: GROUND STABILIZATION 1. Ground Stabilization Timelines Ground stabilization shall be achieved on any area of a site where land disturbing activities have ceased within the timeframes listed in Table 3 below. It is recommended to stabilize the ground more quickly if practicable. Extensions of time may be approved by the E&SC plan authority based on weather or other site -specific conditions that make compliance impracticable. Portions of a site that are lower in elevation and not expected to discharge during construction may be exempt from the temporary ground cover requirements if identified on the E&SC plan and approved by the E&SC plan authority. Page 7 of 26 Permit No. NCGO10000 Table 3: Required Ground Stabilization Timeframes Stabilize within Site Area this many calendar Timeframe Variations Description days after ceasing land disturbance (a) Perimeter dikes, 7 None swales, ditches, and perimeter slopes 7 None (b) High Quality Water (HQW) Zones N7 • If 10' less in length slopes are or and are not (c) Slopes steeper than steeper than 2:1, 14 days are allowed 3:1 • 7 days for slopes greater than 50' in length and with slopes steeper than 4:1 14 . 7 days for perimeter dikes, swales, ditches, (d) Slopes 3:1 to 4:1 perimeter slopes, and HQW Zones • 10 days for the Falls Lake Watershed • 7 days for perimeter dikes, swales, ditches, 14 perimeter slopes, and HQW Zones (e) Areas with slopes • 10 days for the Falls Lake Watershed unless flatter than 4:1 there is zero slope. 2. Permanent Ground Stabilization Timeline After the permanent cessation of construction activities, any areas with temporary ground stabilization shall be converted to permanent ground stabilization as soon as practicable but in no case longer than 90 calendar days after the last land disturbing activity. Temporary ground stabilization shall be maintained in a manner to render the surface stable against accelerated erosion until permanent ground stabilization is achieved. SECTION F: MATERIALS HANDLING Any structural controls installed to manage construction materials stored or used on site shall be included in the field copy of the E&SC plan. Requirements for handling materials on construction sites shall be as follows: 1.

No concrete or cement slurry shall be discharged from the site. (Note that discharges from onsite concrete plants require coverage under a separate NPDES permit - NCG140000.) Any hardened concrete residue will be disposed of, or recycled on site, in accordance with local and state solid waste regulations. 6. Earthen Material Stock Piles Earthen material stock piles shall be located at least 50 feet away from storm drain inlets and surface waters unless no other alternatives are reasonably available. SECTION G: OPERATION AND MAINTENANCE 1. Modifications to the E&SC Plan Modifications to the approved E&SC plan that require changes to the E&SC measure designs, the drainage areas, or the disturbed areas draining to E&SC measures shall be approved by the E&SC plan authority. Deviations from the approved E&SC plan, or approved revised E&5C plan, shall constitute a violation of this permit unless the deviation is to correct an emergency situation where sediment is being discharged off the site. The E&SC plan authority may allow deviations from the F&SC plan on a case -by -case basis if the deviations are minor adjustments to Page 9 of 26 Permit No. NCGO10000 address minor deficiencies. A minor adjustment shall be the addition of E&SC measures (e.g., silt fence, inlet protection, check dams, rolled erosion control practices, etc.), or the relocation of E&SC measures that would improve the overall stormwater management and sediment control onsite. Minor adjustments shall be noted on the approved E&SC plan and maintained at the job site. 2. Operation and Maintenance The permittee shall install and maintain all temporary and permanent E&SC measures as required by this permit and the approved E&SC plan. 3. Corrective Actions If self -inspections required by this permit identify a need for maintenance of control measures, modifications or additions to control measures, or corrective actions to control sediment or other pollutants, these actions shall be performed as soon as possible considering adverse weather and site conditions. 4. Draw Down of Sediment Basins for Maintenance or Close Out Sediment basins and traps that receive runoff from drainage areas of one acre or more shall use outlet structures that withdraw water from the surface when these devices need to be drawn down for maintenance or close out unless this is infeasible. The circumstances in which it is not feasible to withdraw water from the surface shall be rare (for example, times with extended cold weather). Non -surface withdrawals from sediment basins shall be allowed only when all of the following criteria have been met: (a) The E&SC Plan authority has been provided with documentation of the non -surface withdrawal and the specific time periods or conditions in which it will occur. The non -surface withdrawal shall not commence until the E&SC plan authority has approved these items, (b) The non -surface withdrawal has been reported as an anticipated bypass in accordance with Part III, Section C, Item (2)(c) and (d) of this permit, (c) Dewatering discharges are treated with controls to minimize discharges of pollutants from stormwater that is removed from the sediment basin. Examples of appropriate controls include properly sited, designed and maintained dewatering tanks, weir tanks, and filtration systems, (d) Vegetated, upland areas of the sites or a properly designed stone pad is used to the extent feasible at the outlet of the dewatering treatment devices described in Item(c) above, (e) Velocity dissipation devices such as check dams, sediment traps, and riprap are provided at the discharge points of all dewatering devices, and (f) Sediment removed from dewatering treatment devices described in Item(c) above is disposed of in a manner that does not cause deposition of sediment into waters of the United States. 5. Bypass of E&SC Measures Diversions of stormwater from E&SC measures when the design storm has not been exceeded are not allowed. Bypasses of E&SC measures shall be reported in accordance with Part III, Section C, Item (2)(c) and (d) of this permit. 6. Unavoidable Bypass for Public Safety A bypass may be allowed by the Director if the Director determines that all of the following conditions were met: (a) The bypass is unavoidable to prevent loss of life, personal injury or severe property damage, (b) There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention of stormwater or maintenance during normal periods of equipment downtime or dry weather. This condition is not satisfied if adequate backup controls should have been installed in the exercise of reasonable engineering judgement to prevent a bypass Page 10 of 26 Permit No. NCGO10000 which occurred during normal periods of equipment downtime or preventative maintenance, and (c) the permittee submitted a notice of the bypass per the record -keeping requirements in Part 111, Section C, Item (2)(c) and (d) of this permit. 7. Upset of E&SC Measures Diversions of stormwater from E&SC measures may be considered as an upset if the permittee can demonstrate that all of the following conditions have been met. In any enforcement proceeding, the permittee seeking to establish the occurrence of an upset has the burden of proof. (a) The permittee submitted notice of the upset as required in this general permit and identifies the cause(s) of the upset. (b) The permittee demonstrates that the upset was not caused by operational error, improperly designed treatment or control facilities, lack of preventive maintenance, or careless or improper operation. (c) The permittee agrees to take remedial measures if necessary. Page 11 of 26 Permit No. NCGO10000 PART III SELF -INSPECTION, RECORDKEEPING AND REPORTING SECTION A: SELF -INSPECTIONS Self -inspections are required during normal business hours in accordance with the table below. When adverse weather or site conditions would cause the safety of the inspection personnel to be in jeopardy, the inspection may be delayed until the next business day on which it is safe to perform the inspection. In addition, when a storm event of equal to or greater than 1.0 inch occurs outside of normal business hours, the self -inspection shall be performed upon the commencement of the next business day. Any time when inspections were delayed shall be noted in the Inspection Record.

Erosion and Sedimentation Control (E&SC) Plan A plan developed in compliance with the North Carolina Sedimentation Pollution Control Act of 1973 in G.S. 113A-50 et seq. to prevent sediment resulting from accelerated erosion from being transported off the site of the land -disturbing activity or in waters. 15. Erosion and Sedimentation Control (E&SC) Plan Authority The entity responsible for reviewing and approving the Erosion and Sediment Control Plan. Within some local governments' jurisdictions, this will be a delegated program. Elsewhere, it will be the Division. 16. Erosion and Sediment Control (E&SC) Measure Temporary and permanent practices and devices to prevent sediment resulting from accelerated erosion from being transported off the site of the land -disturbing activity or in waters of the State of North Carolina. E&5C measures, include, but are not limited to, sedimentation traps, sedimentation ponds, rock dams, temporary diversions, temporary slope drains, rock check dams, sediment fence or barriers, all forms of inlet protection, storm drainage facilities, energy dissipaters and stabilization methods of open channels. 17. Ground Cover Any vegetative growth or other material which, when applied to the soil surface, renders the soil surface stable against accelerated erosion. 18. Hazardous Substance Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. 19. Landfill A disposal facility or part of a disposal facility where waste is placed in or on land and which is not a land treatment facility, a surface impoundment, an injection well, a hazardous waste long-term storage facility or a surface storage facility. 20. Normal Business Hours These are generally considered to be between the hours of 6 a.m. and 6 p.m., or when workers are normally present on the construction site. Weekends, state and federal holidays are not considered normal business hours unless construction activities are taking place on the site during those times. Page 24 of 26 Permit No. NCGO10000 21. Notice of Intent The state application form which, when submitted to the Division, officially indicates the facility's notice of intent to seek coverage under a general permit. 22. Permanent Stabilization When all soil disturbing activity is completed and exposed soils have been stabilized with a vegetative cover with a density of at least 80% or covered with a structural stabilization method. Permanent perennial vegetation may include the use of sod, shrubs and ground cover plants mixed with mulching, aggregate or other landscaping techniques. Structural methods include concrete, asphalt, retaining wall or other stabilization techniques. 23. Permittee The person, firm or organizational entity that signed as the financially responsible party on the Erosion and Sedimentation Control Plan. 24. Point Source Discharge of Stormwater Any discernible, confined and discrete conveyance including, but not specifically limited to, any pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from which stormwater associated with industrial activity is or may be discharged to waters of the state. 2 S. Secondary Containment Spill containment for the contents of the single largest tank within the containment structure plus sufficient freeboard to allow for the 25-year, 24-hour storm event. 26. Section 313 Water Priority Chemical A chemical or chemical category which: (a) Is listed in 40 CFR 372.65 pursuant to Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) of 1986, also titled the Emergency Planning and Community Right -to -Know Act of 1986; (b) Is present at or above threshold levels at a facility subject to SARA title III, Section 313 reporting requirements; and (c) Meets at least one of the following criteria: Is listed in appendix D of 40 CFR part 122 on Table I1 (organic priority pollutants), Table III (certain metals, cyanides, and phenols) or Table IV (certain toxic pollutants and hazardous substances); Is listed as a hazardous substance pursuant to section 311(b)(2)(A) of the CWA at 40 CFR 116.4; or Is a pollutant for which EPA has published acute or chronic water quality criteria. 27. Soil Stabilization The use of vegetative, physical or chemical coverage techniques that will restrain accelerated erosion on disturbed soils for temporary or permanent control needs. 28. Stormwater Discharge Outfall (SDO) The point of departure of Stormwater from a discernible, confined, or discrete conveyance, including but not limited to, storm sewer pipes, drainage ditches, channels, spillways, or channelized collection areas, from which stormwater flows directly or indirectly into waters. 29. Stormwater Runoff The flow of water which results from precipitation and which occurs immediately following rainfall or as a result of snowmelt. Page 25 of 26 Permit No. NCGO10000 30. Stormwater Associated with Industrial Activity The discharge from any point source which is used for collecting and conveying stormwater and which is directly related to manufacturing, processing or raw material storage areas at an industrial site. Facilities considered to be engaged in "industrial activities" include those activities defined in 40 CFR 122.26(b)(14). The term does not include discharges from facilities or activities excluded from the NPDES program. 31. Stormwater Pollution Prevention Plan (SWPPP) The elements of the States stormwater pollution prevention program that provide the technology - based requirements designed to protect the state's waters from the adverse impacts of sediments. In North Carolina, the SWPPP for construction activities includes the Erosion and Sedimentation Control Plan, Ground Stabilization, Materials Handling, and Disturbed Area Limit for Special and Threatened Waters. 32. Temporary Stabilization When the establishment of ground cover over all disturbed areas (such as mulching, rolled erosion control products, vegetation, or other material) renders the surface stable against accelerated erosion. Stabilization shall be achieved with the establishment of a uniform and evenly -distributed (i.e., without large bare areas) ground cover with a cover density of at least 80%. 33. Toxic Pollutant Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act. 34. Upset An exceptional incident in which there is unintentional and temporary noncompliance with technology -based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment or control facilities, inadequate treatment or control facilities, lack of preventive maintenance, or careless or improper operation. 35. Visible Sedimentation Solid particulate matter, both mineral and organic, that has been or is being transported by water, air, gravity, or ice from its site of origin that can be seen with the unaided eye. 36. 25-year, 24-hour Storm Event The maximum 24-hour precipitation event expected to be equaled or exceeded, on the average, once in 25 years.
