text: SECTION 1. SHORT TITLE.
  
      This Act may be cited as the ``Acid Deposition and Ozone Control 
  Act of 1997''.
  
  SEC. 2. FINDINGS AND PURPOSES.
  
      (a) Findings.--Congress finds that--
              (1)(A) reducing atmospheric nitrogen oxide will reduce 
          acidic deposition, and the serious adverse effects of acidic 
          deposition on public health, natural resources, building 
          structures, and ecosystems; and
              (B) acidic deposition has been demonstrated to result in 
          increased morbidity in fish and severe damage to water bodies 
          and forest lands;
              (2)(A) reducing atmospheric nitrogen oxide will provide 
          further benefits by decreasing ambient levels of tropospheric 
          ozone, fine particulate matter, and regional haze associated 
          with poor visibility; and
              (B) such conditions have been demonstrated to result in 
          severe threats to public health, including lung irritation, 
          increased incidence of asthma and bronchitis, and increased 
          human morbidity;
              (3)(A) nitrogen deposition into affected watersheds can 
          result in excessive nutrient enrichment leading to algal blooms 
          and increased biological oxygen demand; and
              (B) such conditions can lead to increased morbidity in 
          marine life and severe degradation of economic and recreational 
          opportunities;
              (4) additional reductions in sulfur dioxide beyond levels 
          currently required by the Clean Air Act (42 U.S.C. 7401 et 
          seq.) will result in decreases in acidic deposition, regional 
          haze, and ambient levels of fine particulates;
              (5) the allowance trading program established in the Clean 
          Air Act for the reduction of emissions of sulfur dioxide has 
          been highly effective at creating cost-effective control 
          measures;
              (6) the technology exists to inexpensively reduce sulfur 
          dioxide emissions beyond the levels currently required by the 
          Clean Air Act;
              (7) the ozone transport region established by the Clean Air 
          Act to reduce long-range transport of ozone does not currently 
          include all the States necessary to achieve the intended 
          reduction; and
              (8) this Act shall support the Environmental Protection 
          Agency's stated objective of controlling ground level ozone 
          through regional controls, as developed by the Ozone Transport 
          Assessment Group and referred to in the January 10, 1997, 
          advanced notice of proposed rulemaking for State implementation 
          plans under section 110(k)(5) of the Clean Air Act (42 U.S.C. 
          7410(k)(5)).
      (b) Purposes.--The purposes of this Act are--
              (1) to recognize the scientific evidence that emissions of 
          nitrogen oxide present a substantial threat to public health 
          and the environment;
              (2) to require reductions in the emission of nitrogen 
          oxide;
              (3) to recognize that the means exist to cost-effectively 
          reduce emissions of sulfur dioxide beyond the levels currently 
          required by the Clean Air Act;
              (4) to require reductions in the emission of sulfur 
          dioxide;
              (5) to recognize that tropospheric ozone is a regional 
          problem;
              (6) to recognize that the single ozone transport region 
          created by the Clean Air Act does not currently include all the 
          States necessary to adequately address the problem of ozone; 
          and
              (7) to amend the Clean Air Act to expand the membership in 
          the ozone transport region by using the best currently 
          available science to include those States that contribute to 
          ozone levels in noncompliance areas within the current single 
          ozone transport region.
  
  SEC. 3. CONTROL OF INTERSTATE OZONE AIR POLLUTION.
  
      (a) Additional States.--Section 184(a) of the Clean Air Act (42 
  U.S.C. 7511c(a)) is amended after the first sentence by inserting the 
  following: ``The Administrator, using the best available science and 
  models developed by the Ozone Transport Assessment Group, shall add any 
  State to the single ozone transport region that contributed 4 parts per 
  billion or more to ozone via aerial transport to the ozone level of any 
  noncompliant area in the single ozone transport region for any 1 of the 
  second through tenth worst ozone days that occurred during the previous 
  10 years.''.
      (b) Control Measures.--Not later than 18 months after the date of 
  enactment of this Act, any control measure adopted under section 184(a) 
  of the Clean Air Act (42 U.S.C. 7511c(a)) before the date of enactment 
  of this Act shall apply to any State added to the single ozone 
  transport region under the second sentence of section 184(a) of the 
  Clean Air Act (42 U.S.C. 7511c(a)) after the date of enactment of this 
  Act.
  
  SEC. 4. ADDITIONAL NITROGEN OXIDE EMISSIONS REDUCTIONS.
  
      Section 184 of the Clean Air Act (42 U.S.C. 7511c) is amended by 
  adding at the end the following:
      ``(e) Additional Emissions Reductions.--
              ``(1) In general.--Not later than 18 months after the date 
          of enactment of this subsection, the Administrator shall 
          promulgate regulations requiring reductions in the emissions of 
          nitrogen oxide and sulfur dioxide in any State added to the 
          single ozone transport region under the second sentence of 
          subsection (a) to \1/3\ of the 1990 levels by the year 2003.
              ``(2) Affected units.--The regulations shall apply to 
          affected units, as defined under section 402.
              ``(3) Allowance program.--The Administrator may establish 
          an allowance trading program to carry out this subsection.
              ``(4) Effect on other law.--This subsection shall not 
          affect any law (including regulations) that requires a greater 
          reduction in emissions of nitrogen oxide or sulfur dioxide than 
          is required by this subsection.''.
target: Acid Deposition and Ozone Control Act of 1997 - Amends the Clean Air Act to require the Administrator of the Environmental Protection Agency to add to the single ozone transport region (comprised of the States of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and the Consolidated Metropolitan Statistical Area including the District of Columbia) any State that contributed at least four parts per billion to ozone via aerial transport to the ozone level of any noncompliant area in the region for any one of the second through tenth worst ozone days that occurred during the previous ten years. Applies to any State so added, not later than 18 months after enactment of this Act, any control measure adopted under the ozone transport regions provisions. 
  Requires the Administrator to promulgate regulations requiring nitrogen oxide and sulfur dioxide emissions reductions in any State added under this Act to one-third of 1990 levels by the year 2003.
