Projects that do not meet the Low Density requirements shall meet the following requirements: 1. Stormwater runoff from the entire site must be treated by structural stormwater controls (BMPs) that are designed to remove eighty-five percent (85%) of the average annual amount of Total Suspended Solids (TSS). Stormwater runoff that drains directly to Nutrient Sensitive Waters (NSW) must also be treated to remove thirty percent (30%) of Total Nitrogen (TN) and Total Phosphorus (TP),' 2. All BMPs must be designed in accordance with the version of the NC DWQ Stormwater Best Management Practices Manual that is in place on the date of stormwater management plan submittal. Alternative designs may be approved if the applicant can show that the design provides equal or better water quality protection than the practices specified in the manual.9 3. DWQ may add specific stormwater management requirements on a case-by- case basis in order to ensure that a proposed activity will not violate water quality standards. t0 4. DWQ may approve Low Impact Developments (LIDs) that meet the guidance set forth in the Low Impact Development; A Guidebook for North Carolina." 5, Proposed new development undertaken by a local government solely as a public road project shall follow the requirements of the NC DOT BMP Toolbox rather than Items (1)-(4) above. 12 B. Submittal Requirements. The that require written authorization as projects that require an Isolat be sent to the Wetlands, Buffe listed below apply only to projects icable General Certification as well iy required documentation shall mpliance and Permitting Unit at i. Projects that are Subject to Another DWQ Stormwater Program: If the project is subject to another DWQ stormwater program, such as the 20 Coastal Counties, HQW QRW or state -implemented Phase ll NPDES, then the applicant shall submit a copy of the stormwater approval letter before any impacts occur on site. 13 ii. Projects that are Subject to a Certified Community's Stormwater Program. If the project is subject to a certified local government's stormwater program, then the applicant shall submit one set of approved stormwater management plan details and calculations with documentation of the local government's approval before any impacts occur on site.5 iii. Projects Not Covered Under Items (i) or (li). If the project is not subject to another DWQ Stormwater Program or a Certified Community's stormwater program, then it shall be reviewed and approved by the DWQ through the Water Quality Certification authorization process. a. Low Density. For low density projects, the applicant shall submit two copies of the DWQ Low Density Supplement Form with all required items.13 Water Quality Certification No. 3890 10 Water Quality Certification No. 3890 b. High Density. For high density projects, the applicant shall submit two copies of a DWQ BMP Supplement Form and all required items at the specified scales for each BMP that is proposed.13 iv. Phasing. Stormwater management pians may be phased on a case-by-case basis, with the submittal of a final stormwater management plan per Items (i) -(iii) above required for the current phase and a conceptual stormwater management plan for the future phase(s). The stormwater management plan for each future phase must be approved by the appropriate, entity before construction of that phase is commenced. The approved stormwater managementplan for each future phase must be constructed and operational before any, permanent building or other structure associated with that phase is occupied. v, Stormwater Management Plan Modifications. The stormwater management plan may not be modified without prior written authorization from the entity that approved the plan. If the project is within a Certified Community, then the applicant shall submit one set of approved stormwater management plan details and calculations with documentation of the local government's approval for record' -keeping purposes. If the project is subject to DWQ review, then the applicant shall submit two copies of the appropriate Supplement Forms per Item (iii) above for any,BMPs that have been modified for DWQ's review and approval,15 The stormwater requirement for 401 applications is codified in 15A NCAC 02H .0506(b)(5) and x (c)(5) Non erosive discharge rates are required in SL 2008-211§2(b)(1).
