to an enforcement action by the Division of Water Quality in accordance with North Carolina General Statute
143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from complying with any and
all statutes, rules, regulations, or ordinances which may be imposed by other government agencies (local,
state, and federal) which have jurisdiction.
