( 2 ) Limitations that are identified in the Area Contingency Plans for the COTP zones in which the vessel operates, including— ( i ) Ice conditions;
( ii ) Debris;
( iii ) Temperature ranges; and
( iv ) Weather-related visibility.
( b ) The COTP may reclassify a specific body of water or location within the COTP zone. Any reclassifications will be identified in the applicable Area Contingency Plan. Reclassifications may be to— ( 1 ) A more stringent operating environment if the prevailing wave conditions exceed the significant wave height criteria during more than 35 percent of the year; or
( 2 ) A less stringent operating environment if the prevailing wave conditions do not exceed the significant wave height criteria for the less stringent operating environment during more than 35 percent of the year.
( c ) Response equipment must— ( 1 ) Meet or exceed the criteria listed in table 1 of appendix B of this part;
( 2 ) Be capable of functioning in the applicable operating environment; and
( 3 ) Be appropriate for the petroleum oil carried.

Note 1:
Gulf Coast Tier 1 is higher due to greater potential spill size and frequency in that area, and it is assumed that dispersant stockpiles would be centralized in the Gulf area. Alternative application ratios may be considered based on submission to Coast Guard Headquarters, Office of Marine Environmental Response Policy (CG-MER) of peer-reviewed scientific evidence of improved capability.
( 3 ) Dispersant stockpiles, application platforms, and other supporting resources must be ensured available in a quantity and type sufficient to treat a vessel's worst case discharge (as determined by using the criteria in Section 8 of appendix B), or in quantities sufficient to meet the requirements in Table 155.1050(k), whichever is the lesser amount.
( l ) The owner or operator of a vessel carrying groups I through IV petroleum oil as a primary cargo must identify in the response plan, and ensure their availability through contract or other approved means, response resources necessary to provide aerial oil tracking to support oil spill assessment and cleanup activities. Vessels operating on inland rivers are not required to comply with this paragraph. ( 1 ) Aerial oil tracking resources must be capable of arriving at the site of a discharge in advance of the arrival of response resources identified in the plan for tiers 1, 2, and 3 Worst Case Discharge response times, and for a distance up to 50 nautical miles from shore (excluding inland rivers).
( 2 ) Aerial oil tracking resources must include the following: ( i ) Appropriately located aircraft and personnel capable of meeting the response time requirement for oil tracking in § 155.1050(l)(1) of this section;
( ii ) Sufficient numbers of aircraft, pilots, and trained observation personnel to support oil spill operations, commencing upon initial assessment, and capable of coordinating on-scene cleanup operations, including dispersant, in-situ burning, and mechanical recovery operations;
( iii ) Observation personnel must be trained in the protocols of oil spill reporting and assessment, including estimation of slick size, thickness, and quantity. Observation personnel must be trained in the use of assessment techniques in ASTM F1779-08 (incorporated by reference, see § 155.140), and familiar with the use of pertinent guides, including, but not limited to, NOAA's “Open Water Oil Identification Job Aid for Aerial Observation” and the “Characteristic Coastal Habitats” guide; and

( m ) [Reserved]
( n ) The owner or operator of a vessel carrying groups I through IV petroleum oil as a primary cargo must identify in the response plan and ensure the availability of, through contract or other approved means, response resources necessary to perform shoreline protection operations. ( 1 ) The response resources must include the quantities of boom listed in table 2 of appendix B of this part, based on the areas in which the vessel operates.
( 2 ) Vessels that intend to offload their cargo at the Louisiana Offshore Oil Port (LOOP) marine terminal are not required to comply with the requirements of this paragraph when they are within the offshore area and under one of the following conditions: ( i ) Approaching or departing the LOOP marine terminal within the LOOP Shipping Safety Fairway, as defined in 33 CFR 166.200.
( ii ) Moored at the LOOP marine terminal for the purposes of cargo transfer operations or anchored in the designated anchorage area awaiting discharge.
( o ) The owner or operator of a vessel carrying groups I through IV petroleum oil as a primary cargo must identify in the response plan and ensure the availability of, through contract or other approved means, an oil spill removal organization capable of effecting a shoreline cleanup operation commensurate with the quantity of emulsified petroleum oil to be planned for in shoreline cleanup operations. ( 1 ) The shoreline cleanup resources required must be determined as described in appendix B of this part.
( 2 ) Vessels that intend to offload their cargo at the Louisiana Offshore Oil Port (LOOP) marine terminal are not required to comply with the requirements of this paragraph when they are within the offshore area and under one of the following conditions: ( i ) Approaching or departing the LOOP marine terminal within the LOOP Shipping Safety Fairway as defined in 33 CFR 166.200.
( ii ) Moored at the LOOP marine terminal for the purposes of cargo transfer operations or anchored in the designated anchorage area awaiting discharge.
( p ) Appendix B of this part sets out caps that recognize the practical and technical limits of response capabilities for which an individual vessel owner or operator can contract in advance. Table 6 in appendix B lists the contracting caps that are applicable, as of February 18, 1993, and that are slated to apply on February 18, 1998. The owner or operator of a vessel carrying groups I through IV petroleum oil as a primary cargo, whose required daily recovery capacity exceeds the applicable contracting caps in table 6, shall identify commercial sources of additional equipment equal to twice the cap listed for each tier or the amount necessary to reach the calculated planning volume, whichever is lower, to the extent that this equipment is available. The equipment so identified must be capable of arriving on scene no later than the applicable tier response times contained in § 155.1050(g) or as quickly as the nearest available resource permits. A response plan must identify the specific sources, locations, and quantities of this additional equipment. No contract is required.
( q ) The Coast Guard will continue to evaluate the environmental benefits, cost efficiency and practicality of increasing mechanical recovery capability requirements. This continuing evaluation is part of the Coast Guard's long term commitment to achieving and maintaining an optimum mix of oil spill response capability across the full spectrum of response modes. As best available technology demonstrates a need to evaluate or change mechanical recovery capacities, a review of cap increases and other requirements contained within this subpart may be performed. Any changes in the requirements of this section will occur through a public notice and comment process. During this review, the Coast Guard will determine if established caps remain practicable and if increased caps will provide any benefit to oil spill recovery operations. The review will include and evaluation of: ( 1 ) Best available technologies for containment and recovery;
( 2 ) Oil spill tracking technology;
( 3 ) High rate response techniques;
( 4 ) Other applicable response technologies; and
( 5 ) Increases in the availability of private response resources.
