285.617—What activities require a revision to my SAP, and when will MMS approve the revision?

(a) You must notify MMS in writing before conducting any activities not described in your approved SAP, describing in detail the type of activities you propose to conduct. We will determine whether the activities you propose are authorized by your existing SAP or require a revision to your SAP. We may request additional information from you, if necessary, to make this determination.
(b) The MMS will periodically review the activities conducted under an approved SAP. The frequency and extent of the review will be based on the significance of any changes in available information and on onshore or offshore conditions affecting, or affected by, the activities conducted under your SAP. If the review indicates that the SAP should be revised to meet the requirements of this part, we will require you to submit the needed revisions.
(c) Activities for which a proposed revision to your SAP will likely be necessary include:
(1) Activities not described in your approved SAP;
(2) Modifications to the size or type of facility or equipment you will use;
(3) Changes in the surface location of a facility or structure;
(4) Addition of a facility or structure not contemplated in your approved SAP;
(5) Changes in the location of your onshore support base from one State to another, or to a new base requiring expansion;
(6) Changes in the location of bottom disturbances (anchors, chains, etc.) by 500 feet (152 meters) or greater from the approved locations. If a specific anchor pattern was approved as a mitigation measure to avoid contact with bottom features, any change in the proposed bottom disturbances would likely trigger the need for a revision;
(7) Structural failure of one or more facilities; or
(8) Changes to any other activity specified by MMS.
(d) We may begin the appropriate NEPA analysis and other relevant consultations when we determine that a proposed revision could:
(1) Result in a significant change in the impacts previously identified and evaluated;
(2) Require any additional Federal authorizations; or
(3) Involve activities not previously identified and evaluated.
(e) When you propose a revision, we may approve the revision if we determine that the revision is:
(1) Designed not to cause undue harm or damage to natural resources; life (including human and wildlife); property; the marine, coastal, or human environment; or sites, structures, or objects of historical or archaeological significance; and
(2) Otherwise consistent with the provisions of sub section 8(p) of the OCS Lands Act.
