§148.400   What does this subpart do?

(a) This subpart prescribes requirements under 33 U.S.C. 1504(b) for the activities that are involved in site evaluation and pre-construction testing at potential locations for deepwater ports and that may:

(1) Adversely affect the environment;

(2) Interfere with authorized uses of the Outer Continental Shelf; or

(3) Pose a threat to human health and welfare.

(b) For the purpose of this subpart, “site evaluation and pre-construction testing” means studies performed at potential deepwater port locations, including:

(1) Preliminary studies to determine the feasibility of a site;

(2) Detailed studies of the topographic and geologic structure of the ocean bottom to determine its ability to support offshore structures and other equipment; and

(3) Studies done for the preparation of the environmental analysis required under §148.105 of this part.

§148.405   What are the procedures for notifying the Commandant (CG-5P) of proposed site evaluation and pre-construction testing?

(a) Any person who wants to conduct site evaluation and pre-construction testing at a potential site for a deepwater port must submit a written notice to the Commandant (CG-5P) at least 30 days before the beginning of the evaluation or testing. The Commandant (CG-5P) advises and coordinates with appropriate Federal agencies and the States concerning activities covered by this subpart.

(b) The written notice must include the following:

(1) The names of all parties participating in the site evaluation and pre-construction testing;

(2) The type of activities and the way they will be conducted;

(3) Charts showing where the activities will be conducted and the locations of all offshore structures, including pipelines and cables, in or near the proposed area;

(4) The specific purpose for the activities;

(5) The dates when the activities will begin and end;

(6) The available data on the environmental consequences of the activities;

(7) A preliminary report, based on existing data, of the historical and archeological significance of the area where the proposed activities are to take place. The report must include contacts made with any appropriate State liaison officers for historic preservation; and

(8) Additional information, if necessary, in individual cases.

(c) For the following activities, the notice only needs the information required in paragraphs (b)(1), (b)(2), and (b)(5) of this section, as well as a general indication of the proposed location and purpose of the activities, including:

(1) Gravity and magneto-metric measurements;

(2) Bottom and sub-bottom acoustic profiling, within specified limits, without the use of explosives;

(3) Sediment sampling of a limited nature using either core or grab samplers, and the specified diameter and depth to which the sampling would penetrate if geological profiles indicate no discontinuities that may have archeological significance;

(4) Water and biotic sampling if the sampling does not adversely affect shellfish beds, marine mammals, or an endangered species, or if the sampling is permitted by another Federal agency;

(5) Meteorological measurements, including the setting of instruments;

(6) Hydrographic and oceanographic measurements, including the setting of instruments; and

(7) Small diameter core sampling to determine foundation conditions.

(d) A separate written notice is required for each site.

§148.410   What are the conditions for conducting site evaluation and pre-construction testing?

(a) No person may conduct site evaluation and pre-construction testing unless it complies with this subpart and other applicable laws.

(b) Measures must be taken to prevent or minimize the effect of activities under §148.400(a) of this part.

[USCG-1998-3884, 71 FR 57651, Sept. 29, 2006, as amended by USCG-2013-0397, 78 FR 39177, July 1, 2013]

§148.415   When conducting site evaluation and pre-construction testing, what must be reported?

(a) When conducting site evaluation or pre-construction testing, the following must be immediately reported by any means to the Commandant (CG-5P):

(1) Any evidence of objects of cultural, historical, or archeological significance;

(2) Any adverse effect on the environment;

(3) Any interference with authorized uses of the Outer Continental Shelf;

(4) Any threat to human health and welfare; and

(5) Any adverse effect on an object of cultural, historical, or archeological significance.

(b) Within 120 days after the site evaluation or pre-construction testing, a final written report must be submitted to the Commandant (CG-5P) that contains:

(1) A narrative description of the activities performed;

(2) A chart, map, or plat of the area where the activities occurred;

(3) The dates when the activities were performed;

(4) Information on the adverse effects of items reported under paragraph (a) of this section;

(5) Data on the historical or archeological significance of the area where the activities were conducted, including a report by an underwater archeologist; and

(6) Any additional information required by the Commandant (CG-5P) on a case-by-case basis.

[USCG-1998-3884, 71 FR 57651, Sept. 29, 2006, as amended by USCG-2013-0397, 78 FR 39177, July 1, 2013]

§148.420   When may the Commandant (CG-5P) suspend or prohibit site evaluation or pre-construction testing?

(a) The Commandant (CG-5P) may order, either in writing or orally, with written confirmation, the prohibition or immediate suspension of any activity related to site evaluation or pre-construction testing when the activity threatens to harm:

(1) Human life;

(2) Biota;

(3) Property;

(4) Cultural resources;

(5) Any valuable mineral deposits; or

(6) The environment.
