| (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.
