(c) When proposing site assessment activities in an area BOEM previously considered, BOEM will review your SAP to determine if its impacts are consistent with those previously considered. If the anticipated effects of your proposed SAP activities are significantly different than those previously anticipated, we may determine that additional NEPA and other relevant Federal reviews are required. In that case, BOEM will notify you of such determination, and you must submit information required in paragraph (b) of this section as appropriate.

Your SAP will be processed based on whether it is submitted before or after your lease is issued:

(a) BOEM will review your submitted SAP, and additional information provided pursuant to § 585.611, to determine if it contains the information necessary to conduct our technical and environmental reviews.

(1) Measures designed to avoid or minimize adverse effects and any potential incidental take of the endangered or threatened species or marine mammals;

(2) Measures designed to avoid likely adverse modification or destruction of designated critical habitat of such endangered or threatened species;

(3) Your agreement to monitor for the incidental take of the species and adverse effects on the critical habitat, and provide the results of the monitoring as required;

(4) Your agreement to perform any relevant terms and conditions of the Incidental Take Statement that may result from the ESA consultation; and

(5) Your agreement to perform any relevant mitigation measures under an MMPA incidental take authorization.

(a) If you, your subcontractors, or any agent acting on your behalf discovers a potential archaeological resource while conducting construction activities, or any other activity related to your project, you must:

(1) Immediately halt all seafloor-disturbing activities within the area of the discovery;

(2) Notify BOEM of the discovery within 72 hours; and

(3) Keep the location of the discovery confidential and not take any action that may adversely affect the archaeological resource until we have made an evaluation and instructed you on how to proceed.

(b) We may require you to conduct additional investigations to determine if the resource is eligible for listing in the National Register of Historic Places under 36 CFR 60.4. We will do this if:

(1) The site has been impacted by your project activities; or

(2) Impacts to the site or to the area of potential effect cannot be avoided.
