Stormwater Fast-Track Permitting Stormwater Rules Review Re-Adoption Annette Lucas, PE NC Division of Energy, Mineral and Land Resources Stormwater Program
PERMIT Stormwater Fast ‐ Track Permitting
Fast ‐ Track: Legislative Mandate § 143-214.7B requires that the fast-track permitting program include: - Issuance of permits without a technical review. - A process for insuring compliance with MDC. - A process for establishing liability. - Specification of who is qualified to submit. Fast track permits must comply with state WQ standards.
Fast ‐ Track: The Team’s Approach Instead of reviewing plans at initial application, DEMLR will review as-builts for compliance with the MDC.
Is project Incomplete: May re ‐ submit. eligible & No Ineligible: May submit to regular application or express programs. complete? Yes Authorization to construct permit. Project constructed & completed. Applicant submits as ‐ builts. Applicant brings project into DEMLR reviews as ‐ builts within compliance with MDC and submits 15 days for completeness and updated as ‐ builts. 40 days for compliance. Yes Do the A Schedule for No as ‐ builts comply Compliance in with the MDC? 30 days? No No Yes Enforcement action. Final permit.
Regular V. Express Permitting Regular/Express Fast ‐ Track Who may submit Licensed prof. PE # of submittals/permits 1 2 Time for initial permit Up to 90 days Up to 30 days Vary from MDC? Yes No Engineer of record required? No Yes Yardstick for compliance Approved plans MDC
Rules Review & Re ‐ Adoption
Rule Re-Adoption: Legislative Mandate § 150B-21.3A directs state agencies to review and update their rules every 10 years. A single rule ‐ making Fast ‐ track/ Rules Review MDC & Re ‐ Adoption
Benefits of Rule Re-Adoption: • Decreases repetition • Clarifies requirements • Incorporates current technology • Improves consistency • Codifies policies that are requirements

Most updates are organizational. . . Several substantive changes: • MDC & fast ‐ track • Project density • Disconnection instead of swales • Treatment volume in Coastal Counties • Coastal County exemptions universal • Vegetated setbacks in Non ‐ Coastal HQW & ORW
Codifies method for computing project density BUA Density = Project Area BUA – existing BUA Density = Project Area – existing BUA Project area excludes: • Areas below the Normal High Water (NHW); and • Coastal wetlands.
Encourages disconnection instead of swales ( b) DIFFUSE FLOW. Projects shall be designed to maximize diffuse flow through vegetated areas and minimize channelization of flow; (c) VEGETATED CONVEYANCES. Stormwater that cannot be released as diffuse flow shall be transported by vegetated conveyances.

Andrew Anderson, NCSU ‐ BAE
Make Coastal County Exemptions Universal Stormwater program does not apply to: • Minor modifications. • Projects that already have a stormwater permit. • Projects with vested rights.
Vegetated setbacks in Non-Coastal HQW & ORW Current Proposed Low density 30 feet 30 feet High density None 30 feet Why? • NPDES has 30 feet for both low and high density. • Setbacks are needed to protect use support & avoid flooding problems.
