In future
submissions, OMB requests the agency provide more specific CFR
citations to the requirements described in each information
collection to avoid confusions about the scope of approvals.

EPA is revising its engine emission
standards for new marine diesel engines with per cylinder
displacement at or above 30 liters (called Category 3 marine diesel
engines) installed on U.S. vessels, under section 213 of the Clean
Air Act. The final standards are equivalent to the nitrogen oxides
(NOx) limits recently adopted by the International Maritime
Organization and are based on the position advanced by the United
States Government as part of the international negotiations.
Near-term standards will begin to apply to new engines in 2011 and
to existing engines as soon as certified remanufacture systems
become available. Long-term standards for new engines call for an
80 percent NOx reduction from Tier 1 and will take effect in 2016.
The levels for the final standards are consistent with the
provisions of Section 213. We are also creating a revision to our
diesel fuel program under Section 211 of the Act to allow for the
manufacture and sale of marine diesel fuel with a sulfur content up
to 1000 ppm for use in Category 3 engines. This rule is part of a
coordinated strategy for ensuring that all ships that affect U.S.
air quality will be required to meet stringent NOx and fuel sulfur
requirements. Another component of this strategy consists of
pursuing Emission Control Area (ECA) designation in accordance with
Annex VI of the International Convention for the Prevention of
Pollution from Ships. ECA designation will ensure that all ships
are required to meet stringent NOx and fuel sulfur requirements
while operating within 200 nautical miles of most U.S. coasts. The
U.S. Government forwarded a proposal to IMO to amend Annex VI to
designate U.S. coasts as an ECA. This proposal to amend Annex VI
was approved in principle and circulated for adoption. We expect
the proposed ECA amendment will be adopted at MEPC 60, in March
2010. If this amendment is not adopted in a timely manner by IMO,
we intend to take supplemental action to control emissions from
vessels that affect U.S. air quality.
This is a new regulation under
the Clean Air Act. We have adopted emission standards for Category
3 marine diesel engines, which were previously unregulated. The
previous collection was limited to Category 1 and Category 2
commercial marine diesel engines (up to 30 liters per cylinder),
industrial spark-ignition engines, and recreational marine diesel
engines.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
