Management of National Air Quality
  • Emission Standards
  • Air Quality Standards
  • Pollution Taxes
  • Cost - Benefit Analysis
  • Risk Standards
air pollution
Air Pollution
  • Often disregarded as a health and safety issue.
  • May not have been properly appreciated by the public. Serious health related problems take a long time to show up as a result of exposure to air pollutants.
  • The health costs of air pollution traditionally have been greatly under-estimated.

Water Pollution

  • Problems are more noticeable and immediate in their effect.
  • Often recognized before it reaches crisis proportions.
  • Public complaints are immediate.
kinds of law
Kinds of Law
  • Common Law
    • The body of law that has grown out of common tradition and usage, as stated in court decisions - usually concerns private rights

Statute Law

    • The body of law that has been passed by legislators (e.g: US Congress) and stated in formal documents - usually concerns rights of general public
    • Statute laws usually do not take away a citizen\'s right to sue
other legal terms
Other Legal Terms
  • Tort : A willful or negligent injury to a person, property, or reputation
  • Nuisance : Unlawful invasion of a possessor\'s interest in the reasonable use and enjoyment of property
    • Private Nuisance
      • Only the plaintiff or a small, well defined class of plaintiffs are affected
      • Plaintiff(s) could take action
    • Public Nuisance
      • Many people in the community are affected
      • Only government could take action
history of air pollution
History of Air Pollution
    • Prior to 1940     : Very little by way of formal regulations. Air Pollution Control Ordinance (around 1815)
    • 1940 - 1955       : Initiation of practical efforts in the US as a result of LA type fog
    • 1955 - 2010   : Development, Implementation & Modification of Regulations
    • 2001: New approaches to apply standards
  • Note :
  • Before Passage of 1970 Clean Air Amendments, Air Pollution Laws were sometimes similar to Water Pollution Laws

  • To protect human health and the air environment
  • To establish a national research and development program to prevent and to control air pollution
  • To provide federal assistance and leadership to state and local governments for air pollution programs
  • To develop specific standards for hazardous air pollutants
clean air act amendments of 19701

  • Important legal event in the US federal air pollution control field
  • Creation of Environmental Protection Agency

Policy

air quality criteria
Air Quality Criteria
  • Expressions of the latest scientific knowledge based on the knowledge of experts.
  • Describe the effects that can be expected to occur beyond "excedence" pollutant level for a specified time period.
  • Miscellaneous
    • Exposure
    • Combination of pollutants etc
air quality standards
Air Quality Standards
  • Prescribe the pollutant levels that cannot be legally exceeded during a specific time period in a specific geographic region
  • 1970 :
    • Primary Standards
      • Protection of public health (to be achieved regardless of cost and within the specified time limit)
    • Secondary Standards
      • To protect public from known and anticipated adverse effects
      • Time schedule to be determined by state and local governments
emission standards
Emission Standards
  • Emission Standards
    • " _ _ _ _ _ _ to limit the amount or concentration of a contaminant that may be emitted from a source ".
  • Visible emission standards.
  • Particulate emission standards.
  • Particulate process weight (or mass) standards.
  • Gas concentration standards.
  • Prohibition of emissions.
  • Regulation of fuel.
  • Zoning restrictions.
  • Dispersion based standards.
case for national standards
Case For National Standards
      • Unfair economic advantages (by state)
      • Competition for lower standards.
  • Federal Standards for :
    • automobiles
    • aircraft
    • industries supplying basic needs
    • "New Source " performance standards
  • Initial NSPS issued on December 23, 1971
    • Steam Generators
    • Portland Cement Plants
    • Incinerators
    • Nitric acid and H2SO4 plants
prevention of significant deterioration program division of u s
Prevention of Significant Deterioration ProgramDivision of U.S.
  • Class I :This class covers pristine areas of the country and no change from current air quality will be allowed
  • Class II :Almost all other areas where moderate change in air quality will be allowed
  • Class III:Industrialized areas where substantial growth will be allowed, and where the increase in concentration of pollutants up to the federal standards will be insignificant
prevention of significant deterioration
Prevention Of Significant Deterioration

1. Applies to new or modified sources constructed after March 19,1979.

2. Potential emissions of 100 tons/year of any single pollutant, or a combined total of 250 tons/year of all pollutants.

3. Best available control technology (BACT) applies to all sources covered.

4. In regions where ambient air quality standards are not being met, a new source is required to provide “Emission Offsets”.
