The Division is hereby notifying you that permit SW8 060717 has been renewed on October 9, 2020, and shall be effective until October 26, 2028. For your records, please find enclosed a renewed, updated, and re -issued permit and a copy of the renewal application. Please keep this permit on file at all times. Please note that the renewed, updated, and re -issued permit does not impose new or different terms; it merely restates some of the previous terms to provide you with a better understanding of your obligations under the permit. The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the terms and conditions of this state stormwater permit.

This permit is 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 changes of 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. 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.
