(a) A permit for a Class I bedded salt cavern disposal well shall include expressly or by reference the following conditions.
  (1) A sign shall be posted at the well site which shall show the name of the company, company well number, and commission permit number. The sign and identification shall be in the English language, clearly legible, and shall be in numbers and letters at least one inch high.
  (2) An all-weather road shall be installed and maintained to allow access to the disposal well and related facilities.
  (3) The wellhead and associated facilities shall be painted, if appropriate, and maintained in good working order without detectable leaks.
  (4) Secondary containment of the wellhead shall consist of a diked, impermeable pad or sump.
  (5) The executive director may prescribe additional requirements for Class I bedded salt cavern disposal wells in order to protect underground sources of drinking water, and fresh or surface water from pollution.
  (6) The obligation to implement the plugging and abandonment plan and the post-closure plan survives the termination of a permit or the cessation of injection activities. The requirement to maintain an approved plan is directly enforceable regardless of whether the requirement is a condition of the permit.
(b) Pressure control equipment including blowout preventers or a wellhead with closeable valves shall be required to be installed and maintained in proper operating condition at all times at the casing head, extending from the time of advancing the surface casing hole after conductor casing is set, to the time of well closure, to safeguard against any pressure imbalance which might cause a backflow, blowout, or fracturing of the salt to occur.
