						  and submit an amended registration form to the Department within 30 days in
						  accordance with §
													245.41 (relating to tank
						  registration requirements).
(b)
						  Owners and operators shall continue operation and maintenance of corrosion
						  protection in accordance with §
													245.432 (relating to operation and
						  maintenance including corrosion protection), while the tank is temporarily

													245.435 (relating to reporting and
						  recordkeeping).
(c) Owners and
						  operators shall empty a tank being placed temporarily out-of-service prior to
						  submission of the registration form to the Department unless directed otherwise
						  by the Department. Removed contents shall be reused, treated or disposed of in
						  accordance with State and Federal requirements, such as Chapter 299 (relating
						  to storage and transportation of residual waste) and 29 CFR Part 1910 (relating

						  tank system, remain in the system. Owners and operators shall maintain release
						  detection records required under §

						  functioning.
