General Statutes. [15A NCAC 02T .0105(c)(6)]
5. In the event the permitted facilities change ownership or the Permittee changes their name, a formal
permit modification request shall be submitted to the Division. This request shall be made on official
Division forms, and shall include appropriate property ownership documentation and other supporting
documentation as necessary. The Permittee of record shall remain fully responsible for maintaining
and operating the facilities permitted herein until a permit is issued to the new owner. [15A NCAC
02T .0104]
6. The Permittee shall retain a set of Division approved plans and specifications for the life of the facilities
permitted herein. [15A NCAC 02T .0108(b)(1)]
7. The Permittee shall maintain this permit until all permitted facilities herein are properly closed or
permitted under another permit issued by the appropriate permitting authority. [15A NCAC 02T
.01050)]

8. ° This permit is subject to revocation or unilateral modification upon 60 days' notice from the Division
Director, in whole or part for the requirements listed in 15A NCAC 02T .0110. [ 15A NCAC 02T .0110]
9. Unless the Division Director grants a variance, expansion of the permitted facilities contained herein
shall not be granted if the Permittee exemplifies any of the criteria in 15A NCAC 02T .0120(b). [15A
NCAC 02T .0120]
10. The Permittee shall pay the annual fee within 30 days after being billed by the Division. Failure to pay
the annual fee accordingly shall be cause for the Division to revoke this permit. [15A NCAC 02T
.0105(e)(3)]
