Air Quality

1950s and 60s

Manufacturing
Wood burning
agricultural
road building/dirt roads (sand)

Coal/Power Plants
Nitrous Oxide
Sulfur Dioxide
Particulates
Carbon Dioxide
Methel Mercury (bio cumulates in fish)

Vehicles
CO2
lead
CO
NOx

1970 Clean Air Act
  • Establishes National Ambient Air Quality Standards
    • 6 Criteria Polutents
      • NOx
      • SOx
      • Lead
      • Carbon Monoxide (CO)
      • Particulates
      • Ozone
    • This was about public health
      • EPA sets the standards
      • State Environmental Agencies
        • Command and Control Approach
          • can fine the company
          • compliance
          • cost on industry
            • obvi resistance from industry
    • Carbon Dioxide
      • EPA got sued to count CO2 as a pollutant
        • EPA can now regulate CO2 though they choose not to
  • Cap and Trade
    1. You set a limit (Cap)
    2. Reduce cap over time
  • Coal Fired Power Plants
    • Pre 1970s plants are exempt from the 1970 Clean Air Act
    • Producing 50-60% of our air quality problems
  • Vehicles
    • gas was so cheap. dirt cheap. renewable source of pollution?
      • fuel efficiency standards (CAFE 1977)
        • problems
          • average of your fleet rather than case by case
          • classify SUVs as their own sector
      • Catalytic converters (1975)
      • Speed limit 1973: 55 speed when car is most efficient particularly for pollution emissions.
  • 1990 Clean Air Act Amendments/1991 ISTEA
    • Last truly major environmental piece of legislation passed in this country
    • Created MPOs
      • get a say in how that money is going to be spent
      • recognized the link between transportation and air quality
      • do 3 plans
        • 20 year plan
        • TIP (Transportation Improvement Plan 3-5 years)
        • Projects
      • State Improvement Plans SIPs
        • create by 1990 Amendments
        • MPO plans must be consistent
          • don't have control over zoning
        • SIPs must be approved by EPA
          • non-attainment areas
            • use sanctions
              • main pollutants keeping them out of compliance
                • Ozone/O3 (poison) -->comes from cars
                • increase in VMP is greater than your increase in population -->indicator of sprawl
            • emissions budgets
              • EPA works ut a budget for the Metro area to follow and if they don't...SANCTIONS
            • Air Pollution permits
            • BACT/LAER
            • Offsets
            • Cap and trade
              • lead:
              • NOx : regional, used in the region until a few years ago
              • SOx : they met their target 9 years ahead of time and at a lower cost than what was anticipated
              • Chicago Central Exchange
    • Kyoto
      • took an American idea (cap and trade) and applied it to CO2
          • attainment areas
            • Denver is the only state to come into compliance
  • Denver
    • Attainment Report
      • PM-10
        • Particular Matter of 10 Micromillemeter
        • PM-2.5 is the new reg
      • State Agency dealing with air quality
      • AND regional agency
    • Mention no transportation control measures are going to be taken
      • weird cause they are dealing with supa sprawl
    • Denver just got light rail (T-Rex)
      • 56 stations
      • graduate of this program is in charge of finding out where these stations are going to go
---------------------------------------------------------------------------
What is Air?
  • 80% Nitrogen, 16% Oxygen, traces of argon, neon, carbon dioxide
  • 10,000 feet up
  • Air has the ability to assimilate pollution
  • an airshed is the local air supply
Air Quality in the City of Los Angeles
  • 15 million people
  • 20 million by 2030
  • 80% drive
  • mountain range holds smog in
  • breeze from ocean side
  • desert
Current situation
2nd smoggiest in the nation
90% of californians breath unhealth polluted air
78 days

TOD is their only hope
  • ozone levels go down as pop rises
  • LA region has a deadline of 2010 to meet all federal and state air quality standards. If they don't they don't get money federal highway funds
  • the gap between what is needed for federal attainment levels and what is possible with current technology is 450 tons of pollution per day.
Present Responses
  • Three government agencies with direct authority to address air quality concerns in the LA region:
  • California Air Resources Board
  • South Coast Air Quality Management District
  • Souther Cal Association of Governments (SCAG)
California Air Resources Board
  • Within Department of California EPA
  • 11 members appointed by the governor
  • Created by State Legislature in 1967; 3 goals:
    • Attain and maintain healthy air quality
  • What the ARB Does
    • Sets and enforces emission standards for motor vehicles, fuels, and consumer products
      • health based air qual standards
      • conducts research
      • monitors health
    • AQMD
    • 9 eleted members out of 12
    • makes regulations
      • must be approved by air resources board
    • SCAQMD
    • budget of 86 million
      • funded by fees to industrial polluters
    • Does not have authority to estalish emission standards but does issue permits
  • SCAG
    • Functions as the MPO for 6 county LA region. Covers 15 million people and 38,000
    • make plans
    • identify projects
  • Responses
  • San Joaquin Air Pollution Control District (located next to South Coast AQMD) is imposing air pollution impact fees on new development
  • CAFE and emissions standards are the toughest in the nation
  • Zero Emission Vehicles (ZEV) Program:
    • Requires automakers to sell 2% pure SEVs, 2% advanced technology partial ZEVs, and 6% partial ZEVs.
  • RGG=northeast states and california's cap and trade

Portland, Oregon
  • Thousand Friends of Oregon
    • stop the proposed highway because there will be more emissions
  • LUTRAQ Study
    • Transit Oriented Development
    • Reduce air pollution and the reliance on automobiles...
  • reduced the number of parking spots
  • put stations in
  • worked out
Orenco Station
  • one developer
    • 9 units/acre (you need at least 7/acre for mass transit)
    • mixed used

congestion tax


price (getting the prices right), technology, regulation (public health and welfare), spending programs (choosing to spend money on mass trans vs highways), lifestyles (conservation).
