Staff review of the plans and specifications has determined that the project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session Law 2008-211, as applicable. We are forwarding Permit No. SW8 020612 dated October 30, 2015, for the construction, operation and maintenance of the BMP's and built -upon areas associated with the subject project. This permit shall be effective from the date of issuance until August 16, 2024, and shall be subject to the conditions and limitations as specified therein. Please pay special attention to the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed restrictions, procedures for changing ownership, transferring the permit, and renewing the permit. Failure to establish an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions, to transfer the permit, or to renew the permit, will result in future compliance problems. The following modifications are included and covered by this permit: 1. The increase in approved built -upon area to account for an additional building to be constructed as part of the Steam Decentralization Project as well as a small amount of future built -upon area. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes, and must be filed with the OAH within thirty (30) days of receipt of this permit.
