The mission of the U.S. Environmental Protection Agency is to protect human health and to safeguard the natural environment–air, water, and land–upon which life depends.
UNITED STATES CODE : TITLE 42 : CHAPTER 85
Sec. 7571. Establishment of standards
(A) The Administrator shall, from time to time, issue proposed emission standards applicable to the emission of any air pollutant from any class or classes of aircraft engines which in his judgment causes, or contributes to, air pollution which may reasonably be anticipated to endanger public health or welfare.
(3) The Administrator shall hold public hearings with respect to such proposed standards. Such hearings shall, to
the extent practicable, be held in air quality control regions which are most seriously affected by aircraft emissions. Within 90 days after the issuance of such proposed regulations, he shall issue such regulations with such modifications as he deems appropriate. Such regulations may be revised from time to time.
Sec. 7415. International air pollution
(a) Endangerment of public health or welfare in foreign countries from pollution emitted in United States
Whenever the Administrator, upon receipt of reports, surveys or studies from any duly constituted international agency has reason to believe that any air pollutant or pollutants emitted in the United States cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare in a foreign country or whenever the Secretary of State requests him to do so with respect to such pollution which the Secretary of State alleges is of such a nature, the Administrator shall give formal notification thereof to the Governor of the State in which such emissions originate.
(b) Prevention or elimination of endangerment
The notice of the Administrator shall be deemed to be a finding under section 7410(a)(2)(H)(ii) of this title which
requires a plan revision with respect to so much of the applicable implementation plan as is inadequate to prevent or eliminate the endangerment referred to in subsection (a) of this section. Any foreign country so affected by such emission of pollutant or pollutants shall be invited to appear at any public hearing associated with any revision of the appropriate portion of the applicable implementation plan.
Sec. 7427. Public notification
(a) Warning signs; television, radio, or press notices or information
Each State plan shall contain measures which will be effective to notify the public during any calendar
 on a regular basis of instances or areas in which any national primary ambient air quality standard is exceeded or was exceeded during any portion of the preceding calendar year to advise the public of the health hazards associated with such pollution, and to enhance public awareness of the measures which can be taken to prevent such standards from being exceeded and the ways in which the public can participate in regulatory and other efforts to improve air quality. Such measures may include the posting of warning signs on interstate highway access points to metropolitan areas or television, radio, or press notices or information.
Sec. 7491. Visibility protection for Federal class I areas
(a) Impairment of visibility; list of areas; study and report
(1) Congress hereby declares as a national goal the prevention of any future, and the remedying of any existing,
impairment of visibility in mandatory class I Federal areas which impairment results from manmade air pollution.
(2) Not later than six months after August 7, 1977, the Secretary of the Interior in consultation with other Federal
land managers shall review all mandatory class I Federal areas and identify those where visibility is an important
value of the area. From time to time the Secretary of the Interior may revise such identifications. Not later than
one year after August 7, 1977, the Administrator shall, after consultation with the Secretary of the Interior,
promulgate a list of mandatory class I Federal areas in which he determines visibility is an important value.
