You must take action if you have any of the following conditions:
(a)Any fixed platform well with a casing pressure exceeding its maximum allowable wellhead operating pressure (MAWOP);
(b)Any fixed platform well with a casing pressure that is greater than 100 psig and that cannot bleed to 0 psig through a 1/2-inch needle valve within 24 hours, or is not bled to 0 psig during a casing diagnostic test;
(c)Any well that has demonstrated tubing/casing, tubing/riser, casing/casing, riser/casing, or riser/riser communication;
(d)Any well that has sustained casing pressure
(SCP)and is bled down to prevent it from exceeding its MAWOP, except during initial startup operations described in § 250.522;
(e)Any hybrid well with casing or riser pressure exceeding 100 psig; or
(f)Any subsea well with a casing pressure 100 psig greater than the external hydrostatic pressure at the subsea wellhead. \[76 FR 64462, Oct. 18, 2011. Redesignated at 77 FR 50894, Aug. 22, 2012; 84 FR 21976, May 15, 2019\]
