SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Marine Vessel Emissions Reduction 
Act of 2007''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1) emissions of air pollutants from marine vessels 
        contribute significantly to dangerous air pollution in many 
        areas in the United States;
            (2) current levels of control on those emissions are not 
        adequate to protect air quality and public health;
            (3) to protect air quality and public health, efforts by 
        State and local governments to control emissions from marine 
        vessels must be augmented by the Federal Government;
            (4) although the Environmental Protection Agency may 
        require additional controls on domestic and international 
        marine vessels entering United States ports, significant 
        emission reductions must be achieved in the near future; and
            (5) it is urgent and necessary to require the Administrator 
        of the Environmental Protection Agency to establish standards 
        to reduce emissions of air pollutants from marine vessels in a 
        sufficient period of time to allow all areas in the United 
        States to meet air quality standards in accordance with 
        applicable deadlines.

SEC. 3. MARINE VESSEL FUEL SULFUR.

    Section 211 of the Clean Air Act (42 U.S.C. 7545) is amended--
            (1) by redesignating the first subsection (r) (relating to 
        fuel and fuel additive importers and importation) as subsection 
        (u) and moving that subsection so as to appear at the end of 
        the section; and
            (2) by inserting after subsection (o) the following:
    ``(p) Marine Vessel Fuel Sulfur.--
            ``(1) In general.--Subject to paragraph (3), not later than 
        December 15, 2008, the Administrator shall promulgate 
        regulations that, effective beginning on December 31, 2010, 
        require marine vessels described in paragraph (2) to use fuel 
        that contains not more than 1,000 parts per million of sulfur 
        in the main and auxiliary engines of the vessels.
            ``(2) Applicability.--The regulations promulgated pursuant 
        to paragraph (1) shall apply to all marine vessels, including 
        any vessel flagged in a country other than the United States, 
        at any time at which the vessels are, on entering or leaving a 
        port or offshore terminal of the United States--
                    ``(A) within 200 miles of the west coast of the 
                continental United States; and
                    ``(B) within such distance of the east coast or 
                Gulf coast of the United States, or the shoreline of 
                the Great Lakes or St. Lawrence Seaway, as the 
                Administrator determines to be appropriate for the 
                purpose of protecting public health and the 
                environment.
            ``(3) Interim requirement.--
                    ``(A) In general.--Notwithstanding the requirement 
                of paragraph (1), the Administrator may promulgate 
                regulations under that paragraph that permit marine 
                vessel fuel sulfur content in excess of 1,000 parts per 
                million if the Administrator determines that compliance 
                with the requirement of paragraph (1) is not 
                technically feasible by December 31, 2010.
                    ``(B) Regulations.--If the Administrator makes a 
                determination described in subparagraph (A), the 
                Administrator shall promulgate regulations that require 
                marine vessels--
                            ``(i) beginning on December 31, 2010, to 
                        use fuel that contains--

                        requirement of paragraph (1) on the earliest 
                        practicable date by which compliance is 
                        technically feasible.
            ``(4) Alternative compliance mechanism.--The Administrator 
        may provide for an alternative mechanism of compliance under 
        this subsection for a marine vessel if the Administrator 
        determines that--
                    ``(A) the vessel employs a control technology that 
                reduces emissions from the vessel of sulfur oxides and 
                particulate matter to at least the same degree as the 
                reduction that would be achieved by the vessel through 
                compliance with the applicable fuel sulfur content 
                limitation under this subsection; and
                    ``(B) the emission reductions achieved as described 
                in subparagraph (A) are in addition to any reductions 
                required to achieve compliance with an applicable 
                engine emission standard issued by the Administrator or 
                the head of another Federal agency.
            ``(5) No effect on other authority.--Nothing in this 
        subsection limits or otherwise affects any authority of the 
        Administrator to regulate fuels or fuel additives for use in 
        marine vessels or any other nonroad vehicle or engine under 
        this Act or any other provision of law.''.

SEC. 4. ADVANCED MARINE VESSEL EMISSION CONTROLS.

    Section 213 of the Clean Air Act (42 U.S.C. 7547) is amended--
            (1) by redesignating subsection (d) as subsection (f); and
            (2) by inserting after subsection (c) the following:
    ``(d) Advanced Marine Vessel Emission Controls.--

                    ``(A) In general.--Not later than December 15, 
                2008, the Administrator shall promulgate, and from time 
                to time revise, regulations that establish standards 
                for emissions of oxides of nitrogen, particulate 
                matter, hydrocarbons, and carbon monoxide from newly-
                manufactured and in-use main and auxiliary engines in 
                oceangoing marine vessels that enter or leave a port or 
                offshore terminal of the United States.

                subparagraph (A) shall require, effective beginning on 
                January 1, 2012, that the engines described in that 
                subparagraph achieve the greatest degree of emission 
                reduction achievable through the application of 
                technology that the Administrator determines, in 
                accordance with this paragraph, will be available for

Marine Vessel Emissions Reduction Act of 2007 - Amends the Clean Air Act to direct the Administrator of the Environmental Protection Agency (EPA) to promulgate regulations that, effective beginning on December 31, 2010, require specified marine vessels to use fuel that contains not more than 1,000 parts per million of sulfur in their main and auxiliary engines. Authorizes the Administrator to promulgate interim regulations upon determining that compliance with such requirement is not technically feasible by such date.

Authorizes the Administrator to provide for an alternative mechanism of compliance for a marine vessel if: (1) the vessel employs a control technology that reduces emissions of sulfur oxides and particulate matter to at least the same degree as the reduction that would be achieved through compliance with the applicable fuel sulfur content limitation; and (2) the emission reductions achieved are in addition to any reductions required to achieve compliance with an applicable engine emission standard.

Requires: (1) the Administrator, no later than December 15, 2008, to establish and periodically revise standards for emissions of oxides of nitrogen, particulate matter, hydrocarbons, and carbon monoxide from newly-manufactured and in-use main and auxiliary engines in oceangoing marine vessels that enter or leave a U.S. port or offshore terminal; and (2) such standards to require, beginning January 1, 2012, that the engines achieve the greatest degree of emission reduction achievable through the application of available technology.

Directs the Administrator, upon determining that the maximum level of control required by regulations applicable to on-road, nonroad, and stationary engines or achieved by sources from which control technologies may be transferred, including sources that use advanced aftertreatment technologies, will not be technically achievable by January 1, 2012, to promulgate: (1) standards that require the level of control that will be technically achievable by that date; and (2) additional standards that require either such maximum level of control or the level that will be technically achievable beginning January 1, 2016.
