The RICE NESHAP does not on its face apply to mobile sources, including marine vessels. However, OCS Air Regulations, codified at 40 CFR part 55, specify that vessels are OCS sources when they are (1) permanently or temporarily attached to the seabed and erected thereon and used for the purpose of exploring, developing or producing resources therefrom, within the meaning of section 4(a)(1) of the OCS Lands Act (43 U.S.C. § 1331,et seq.); or (2) physically attached to an OCS facility, in which case only the stationary sources aspects of the vessels will be regulated. 40 CFR 55.2. In addition, the OCS regulations provide that NESHAP requirements apply to a marine vessel that is an OCS source where the provisions are “rationally related to the attainment and maintenance of the Federal or State ambient air quality standards or the requirements of part C of title I of the Act.” 40 CFR 55.13(e). As a result, the commenters have requested that any marine vessel that becomes subject to the requirements of the RICE NESHAP as a result of the operation of 40 CFR part 55, be subject to maintenance-based management practices similar to those proposed for remote spark ignition (SI) engines, rather than the numerical emission limits otherwise applicable. The commenters indicated that these management practices are more appropriate as GACT for existing stationary CI RICE on vessels operating on the OCS. The management practices proposed for remote SI engines andcurrently required in the rule for smaller CI engines include changing the oil and filter, inspecting the air cleaner or spark plugs and inspecting all hoses and belts within specified intervals. Facilities have the option of using an oil analysis program to extend the oil change requirement. The EPA requests comment on the information provided in the public comments regarding compliance by existing stationary CI RICE on vessels operating on the OCS with the current RICE NESHAP emission limits, in particular, the comments related to technological feasibility.
