    (1) ``A'' for fires in ordinary combustible materials where the 
quenching and cooling effects of quantities of water, or solutions 
containing large percentages of water, are of first importance.
    (2) ``B'' for fires in flammable liquids, greases, etc., where a 
blanketing effect is essential.
    (3) ``C'' for fires in electrical equipment where the use of a non-
conducting extinguishing agent is of first importance.
    (c) The number designations for size will start with ``I'' for the 
smallest to ``V'' for the largest. Sizes I and II are considered 
portable extinguishers. Sizes III, IV and V are considered semi-portable 
extinguishers which shall be fitted with suitable hose and nozzle or 
other practicable means so that all portions of the space concerned may

Sec. 146.140  Emergency Evacuation Plan.

    (a) The operator of each manned OCS facility shall develop an 
Emergency Evacuation Plan (EEP) for the facility which addresses all of 
the items listed in paragraph (d) of this section. The EEP may apply to 
more than one facility, if the facilities are located in the same 
general geographic location and within the same Coast Guard Officer in 
Charge, Marine Inspection (OCMI) zone; if each facility covered by the 
EEP is specifically identified in the EEP; and if the evacuation needs 
of each facility are accommodated. The EEP must be submitted to the OCMI 
having jurisdiction over the facility, 30 days before placing the 
facility in operation. The OCMI reviews the EEP to determine whether all 
items listed in paragraph (d) of this section are addressed for each 
facility included in the EEP. If the OCMI determines that all items in 
paragraph (d) of this section are addressed, the OCMI stamps the EEP 
``APPROVED'' and returns it, together with a letter indicating Coast 
Guard approval, to the operator. If the OCMI determines that any item is 
not addressed, the OCMI stamps the EEP ``RETURNED FOR REVISION'' and 
returns the EEP, together with an explanation of the EEP's deficiencies, 
to the operator.

blowouts, and environmental conditions, such as approaching hurricanes 
or ice floes, in which the facility or its personnel would be placed in 
jeopardy and a mass evacuation of the facility's personnel would be 
recommended;
    (10) For each of the circumstances and conditions described under 
paragraph (d)(9) of this section, list the pre-evacuation steps for 
securing operations, whether drilling or production, including the time 
estimates for completion and the personnel required;
    (11) For each of the circumstances and conditions described under 
paragraph (d)(9) of this section, describe the order in which personnel 
would be evacuated, the transportation resources to be used in the 
evacuation, the operational limitations for each mode of transportation 
specified, and the time and distance factors for initiating the 
evacuation; and
    (12) For each of the circumstances and conditions described under 
paragraph (d)(9) of this section, identify the means and procedures--

Sec. 147.1  Purpose of safety zones.

    Safety zones may be established around OCS facilities being 
constructed, maintained, or operated on the Outer Continental Shelf to 
promote the safety of life and property on the facilities, their 
appurtenances and attending vessels, and on the adjacent waters within 
the safety zones. Regulations adopted for safety zones may extend to the 
prevention or control of specific activities and access by vessels or 
persons, and include measures to protect the living resources of the sea 
from harmful agents. The regulations do not encompass the operating 
equipment or procedures used in the drilling for and production of oil, 
gas, or other minerals, or the transportation of oil, gas, or other 
minerals by pipeline except as they relate to the safety of life and 
property on OCS facilities and on the waters adjacent to OCS facilities 
or to the protection of the living resources of the sea within a safety 
zone from harmful agents.



Sec. 147.5  Delegation of authority.

    The authority to establish safety zones and to issue and enforce 
safety zone regulations in accordance with the provisions of this part 
is delegated to District Commanders.



Sec. 147.10  Establishment of safety zones.

    (a) Whenever it comes to the attention of the District Commander 
that a safety zone and regulations may be required concerning any OCS 
facility being constructed, maintained, or operated on the Outer 
Continental Shelf or its appurtenances and attending vessels, or the 
adjacent waters, the District Commander may initiate appropriate inquiry 
to determine whether a safety zone and regulations should be 
established. In making this determination, the District Commander 
considers all relevant safety factors, including existing or reasonably 
foreseeable congestion of vessels, the presence of unusually harmful or 
hazardous substances, and any obstructions within 500 meters of the OCS 
facility. If the District Commander determines that the circumstances 
warrant the establishment of a safety zone and regulations the District 
Commander takes action as necessary consistent with the provisions of 
this part.
    (b) Except as provided in paragraph (c) of this section, a safety 
zone and

[[Page 163]]

necessary regulations may be established concerning any OCS facility 
being constructed, maintained or operated on the Outer Continental 
Shelf, following publication of a notice of proposed rule making in the 
Federal Register and after interested parties have been given the 
opportunity to submit comments. A zone and necessary regulations may be 
in effect during any period when construction equipment and materials 
are within 500 meters of the construction site until the removal of all 
portions of the facility.
    (c) A safety zone and necessary regulations may be established 
without public rule making procedures when the District Commander 
determined that imminent danger exists with respect to the safety of 
life and property on an OCS facility constructed, maintained, or 
operated on the Outer Continental Shelf, its appurtenances and attending 
vessels or adjacent waters. A safety zone and regulations may be made 
effective on the date the rule is published in the Federal Register. 
However, if circumstances require, they may be placed into effect 
immediately, followed promptly by publication in the Federal Register. 
The District Commander may utilize, in addition to broadcast Notices to 
Mariners, Local Notices to Mariners, and Notices to Mariners, 
newspapers, and broadcasting stations to disseminate information 
concerning a safety zone and regulations pertaining thereto. The public 
may comment concerning the establishment of a safety zone or regulations 
under this paragraph. A safety zone or regulations may be modified or 
withdrawn, as appropriate, based on the comments received.
    (d) Geographic coordinates expressed in terms of latitude or 
longitude, or both, are not intended for plotting on maps or charts 
whose referenced horizontal datum is the North American Datum of 1983 
(NAD 83), unless such geographic coordinates are expressly labeled NAD 
83. Geographic coordinates without the NAD 83 reference may be plotted 
on maps or charts reference to NAD 83 only after application of the 
appropriate corrections that are published on the particular map or 
chart being used.

Sec. 147.15  Extent of safety zones.

    A safety zone establishment under this part may extend to a maximum 
distance of 500 meters around the OCS facility measured from each point 
on its outer edge or from its construction site, but may not interfere 
with the use of recognized sea lanes essential to navigation.



Sec. 147.20  Definitions.

    Unless otherwise stated, the term ``attending vessel'' refers to any 
vessel which is operated by the owner or operator of an OCS facility 
located in the safety zone, which is used for the purpose of carrying 
supplies, equipment or personnel to or from the facility, which is 
engaged in construction, maintenance, alteration, or repair of the 
facility, or which is used for further exploration, production, transfer 
or storage of natural resources from the seabed beneath the safety zone.
