  (b) A permit is not required under this rule (327 IAC 3-4) for the discharge, by underground injection, of salt or sulfur-bearing water and waste liquids associated with the recovery of oil and natural gas, if the discharge is pursuant to a valid permit issued under IC 13-4-7-12 [Repealed by P.L.109-1988, SECTION 23.].
