Post -construction Stormwater Runoff Controls for New Development a. In order to fulfill the post -construction minimum measure program requirement the permittee may use the Department's model ordinance, design its own post -construction practices that meet or exceed the rules found in 15A NCAC 02H 1000, or develop its own comprehensive watershed plan that is determined by the Department to meet the post -construction stormwater management measure required by 40 Code of Federal Regulations § 122.34(b)(5) (1 July 2003 Edition). b. The permittee shall meet the requirements of the post -construction program for construction projects that are performed by, or under contract for, the permittee. To meet this requirement, the permittee may either develop the necessary requirements for post -construction controls that will pertain to their own projects, or develop procedures to ensure that the permittee meets these requirements by complying with another entity's Phase II Stormwater Management Programs for post -construction. If the permittee decides to rely on another program for compliance with these program areas for their own projects, they shall indicate in their Stormwater Management Program that the permittee will fully comply with the requirements of the second party's post -construction programs. C. Pursuant to 15A NCAC 02H .0150, for areas draining to Nutrient Sensitive Waters, permittees, delegated programs, and regulated entities must use stormwater control measures (SCMs) that reduce nutrient loading in order to meet local program requirements, while still incorporating the stormwater controls required for the project's density level. Documentation shall be provided where it is not feasible to use stormwater control measures (SCMs) that reduce nutrient loading. In areas where the Department has approved a Nutrient Sensitive Water Urban Stormwater Management Program, the provisions of that program fulfill the nutrient loading reduction requirement. The design volume of SCMs shall take into account the runoff at build out from all surfaces draining to the system. Where streets "convey" stormwater, all SCM shall be sized to treat and control stormwater runoff from all surfaces draining to the SCM including streets, driveways, and other impervious surfaces. 11 PERMIT NO.
