SEC. 3. IN-PORT MARINE VESSEL ZERO EMISSION STAND-
ARDS. 
Section 213 of the Clean Air Act (42 U.S.C. 7547) 
is amended by adding at the end the following: 
‘‘(e) IN-PORT MARINE VESSEL ZERO EMISSION 
STANDARDS.— 
‘‘(1) STANDARDS.—Except as provided in para-
graph (2) and not later than January 1, 2029, the 
Administrator shall promulgate (and from time to 
time revise) standards to eliminate, by not later than 
January 1, 2035, emissions of greenhouse gases and 
air pollutants for which air quality criteria have been 
issued under section 108 from vessels at anchorage 
or at berth in the contiguous zone of the United 
States (as described in Presidential Proclamation 
7219 (43 U.S.C. 1331 note; 64 Fed. Reg. 48701, 
49844)). 
‘‘(2) EXCEPTION.—If the Administrator deter-
mines that standards required by paragraph (1) are 
not technologically or economically feasible, the Ad-
ministrator shall promulgate standards that achieve 
the maximum reduction of the emissions described 
in that paragraph from the vessels described in that 
paragraph that is technologically and economically 
feasible.

‘‘(3) CONSIDERATIONS.—In determining tech-
nological and economic feasibility under paragraph 
(2), the Administrator shall take into account the 
net reduction of emissions of greenhouse gases, the 
net reduction of emissions of air pollutants for which 
air quality criteria have been issued under section 
108, and the potential adverse impacts on public 
health, safety, and the environment, including with 
respect to air quality, water quality, and the genera-
tion and disposal of solid waste.’’.
