 wells).                                       centimeters per minute or a gas leakage rate > 15 cubic feet per
                                               minute is observed, the device must be removed, repaired, and
                                               reinstalled or replaced. Testing must be according to API RP 14B
                                               (ISO 10417:2004) (incorporated by reference as specified in Sec.
                                                250.198) to ensure proper operation, or as approved in your

(ii) USVs...................................  Tested quarterly, not to exceed 120 days. If the device does not
                                               function properly, or if a liquid leakage rate > 400 cubic

                                               minute is observed, the valve must be removed, repaired and
                                               reinstalled, or replaced.
----------------------------------------------------------------------------------------------------------------
(iii) BSDVs.................................  Tested monthly, not to exceed 6 weeks. Valves must be tested for
                                               both operation and leakage. You must test according to API RP 14H
                                               for SSVs (incorporated by reference as specified in Sec.
                                               250.198). If a BSDV does not operate properly or if any fluid
                                               flow is observed during the leakage test, the valve must be
                                               immediately repaired or replaced.

(iv) Electronic ESD logic...................  Tested monthly, not to exceed 6 weeks.
----------------------------------------------------------------------------------------------------------------
(v) Electronic ESD function.................  Tested quarterly, not to exceed 120 days. Shut-in at least one
                                               well during the ESD function test. If multiple wells are tied
                                               back to the same platform, a different well should be shut-in
                                               with each quarterly test.
