SUPPLEMENTARY INFORMATION: On June 7, 2012, the EPA published in the 
Federal Register the proposed rule, ``National Emission Standards for 
Hazardous Air Pollutants for Reciprocating Internal Combustion Engines; 
New Source Performance Standards for Stationary Internal Combustion 
Engines'' (77 FR 33812). The June 7, 2012, action proposed to make 
specific amendments to the national emission standards for hazardous 
air pollutants (NESHAP) for stationary reciprocating internal 
combustion engines (RICE), as well as other regulations. The EPA 
received comments during the public comment period recommending that 
the RICE NESHAP be amended such that for any existing compression 
ignition (CI) RICE on offshore drilling vessels on the Outer 
Continental Shelf (OCS) that become subject to the RICE NESHAP as a 
result of the operation of the OCS regulations (40 CFR part 55), such 
engines may meet the NESHAP through management practices rather than 
numeric emission limits.\1\ This amendment was not contained or 
contemplated in the proposal that was published on June 7, 2012. 
However, the comments indicate several significant issues related to 
application of the NESHAP to regulation of existing marine vessel 
engines located in the OCS as a result of the OCS regulations; in 
particular, whether the numerical standards applicable to other CI 
engines located at area sources (marine vessels located in the OCS are 
generally located at area sources) are technologically feasible for 
existing marine engines located in the OCS. Some commenters note 
specific technological issues relevant to engines on marine vessels in 
the OCS. Commenters suggest that, to the extent marine vessel engines 
become subject to the NESHAP as a result of the OCS regulations, they 
should be subject to generally available control technology (GACT) 
requirements that they believe are more appropriate for these types of 
engines. Given the significance of these issues, the EPA believes it is 
appropriate to request comment on these issues in the context of this 
rulemaking.

    \1\ See document numbers EPA-HQ-OAR-2008-0708-0965 (comment from 
BHP Billiton Petroleum), EPA-HQ-OAR-2008-0708-1004 at p. 3 (comment 
from Truck and Engine Manufacturers Association), EPA-HQ-OAR-2008-
0708-1020 (comment from Anadarko Petroleum Corporation), EPA-HQ-OAR-
2008-0708-1071 (comment from Offshore Operators Committee), EPA-HQ-
OAR-2008-0708-1105 at p. 6 (comment from American Petroleum 
Institute), and EPA-HQ-OAR-2008-0708-1145 at p. 2 (comment from 
Alaska Oil and Gas Association).
---------------------------------------------------------------------------

    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. Sec.  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 and

[[Page 60343]]

currently 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.

How can I get copies of this document and other related information?
