1 Federal Clean Air Act (CAA) State Air Resources Board (ARB) San Joaquin Valley Air Pollution Control District (SJ APCD) and their effects on Kern County Bakersfield ASSE Safety Symposium March 28, 2012 Michael Geyer, PE, CIH, CSP Project Director KERNTEC Environmental

2 Federal Clean Air Act (CAA) U.S. Law authorized the U.S. EPA to establish National Ambient Air Quality Standards (NAAQS) to protect public health and public welfare, and to regulate air emissions from stationary and mobile sources. Goals of the CAA was to set and achieve NAAQS in every state by 1975 in order to address the public health and welfare risks posed by air pollution. REF:

3 State Air Resources Board (ARB) Based on a new U.S. EPA methodology, the ARB determines that 9,000 people die annually due to the amount of fine particulate air pollution in California. The new methodology established that fine particulate matter has a causal link to premature mortality. REF:

4 San Joaquin Valley Air Pollution Control District (SJV APCD) Despite documented air quality progress and the encouraging growth of zero-emission technologies and vehicles, substantial air quality challenges remain for the Valley. The Valley s bowl-shaped topography and consistently-stagnant weather patterns exacerbate the formation and retention of high levels of air pollution. Furthermore, the District does not have direct jurisdiction over the mobile sources that generate about 80% of the Valley s NOx emissions, the most critical precursor for PM2.5 and ozone attainment. REF: SJV APCD Annual Report:

5 San Joaquin Valley Air Pollution Control District (SJV APCD) Challenges will intensify under increasingly stringent National Ambient Air Quality Standards (NAAQS) being considered by the EPA. The EPA has recently proposed several changes to the ozone and PM2.5 NAAQS. Under the anticipated NAAQS changes, even some of the Valley s cleanest counties could begin to record NAAQ S violations despite improving air quality here in the Valley. REF: SJV APCD Annual Report:

6 San Joaquin Valley Air Pollution Control District (SJV APCD) Valley businesses are subject to some of the most stringent air regulations in the nation. Since 1980, emissions from Valley businesses have been reduced by approximately 80-percent. However, new health-based standards established by EPA will demand further reductions in emissions; which will require new technologies that do not yet exist. REF: SJV APCD Annual Report:

7 San Joaquin Valley Air Pollution Control District (SJV APCD) When the Valley exceeded the federal 1-hour ozone standard on seven days in 2010, a $29-million per year non-attainment federal penalty was triggered; to be imposed on the Valley s businesses. This resulted in the District s Governing Board devising a creative solution that minimized individual impact on Valley residents and ensured these funds would return to the Valley for investment in clean-air projects.

8 History of the CAA Legislation enacted by the U.S. Congress Law: U.S. Code Title 42, Chapter 85 Section 7401 to 7671 Regulation: Code of Federal Regulations: 40 CFR 50 to 97 Clean Air Act pre-1970 (1955, 1963 and 1967) Clean Air Act of 1970 Clean Air Act Amendments of 1977 Clean Air Act amendments of 1990 REF:

9 History of the CAA (CONTINUED) Air Pollution Control Act of 1955 First federal legislation involving air pollution. Provided funds for research in air pollution. Clean Air Act of 1963 First federal legislation regarding air pollution control. Established a federal program within the U.S. Public Health Service. Authorized research into monitoring and controlling air pollution. Air Quality Act of 1967 Enacted in order to expand federal government activities. Enforcement proceedings were initiated in areas subject to interstate air pollution fate and transport. First legislation to conduct extensive ambient monitoring studies and stationary source inspections. Expanded studies of air pollutant emission inventories, ambient monitoring techniques, and control technologies. State of California got a waiver to set and enforce its own air standards

10 History of the CAA (CONTINUED) Clean Air Act of 1970 Resulted in a major shift in the federal government's role in air pollution assessment and control. Authorized the development of comprehensive federal and state regulations to limit emissions from both stationary (industrial) sources and mobile sources. Four major regulatory programs affecting stationary sources were authorized: National Ambient Air Quality Standards (NAAQS), State Implementation Plans (SIPs), New Source Performance Standards (NSPS), and National Emission Standards for Hazardous Air Pollutants (NESHAPs). Enforcement authority was substantially expanded. Requirements for control of motor vehicle emissions.

11 History of the CAA (CONTINUED) Clean Air Act Amendments of 1977 Major amendments added to the Clean Air Act. Prevention of Significant Deterioration (PSD) of air quality in areas attaining the NAAQS. Contained requirements pertaining to sources in nonattainment areas for NAAQS. (A non-attainment area is a geographic area that does not meet one or more of the federal air quality standards.) Established major permit review requirements to ensure attainment and maintenance of the NAAQS.

12 History of the CAA (CONTINUED) Clean Air Act Amendments of 1990 Major amendments again added to the Clean Air Act. Substantially increased authority and responsibility of the EPA. New regulatory programs were authorized: Control of acid deposition (acid rain) Issuance of stationary source operating permits. NESHAPs were incorporated into a greatly expanded program for controlling toxic air pollutants. Provisions for attainment and maintenance of NAAQS were substantially modified and expanded. Other revisions: phase out of ozone-depleting chemicals, increased enforcement authority, and expanded research programs in human health risks of air pollution.

15 Clean Air Act - Terms & Conditions National Ambient Air Quality Standards (NAAQS) The Clean Air Act, amended in 1990, requires the EPA to set National Ambient Air Quality Standards for pollutants considered harmful to public health and the environment. (40 CFR Part 50) The Clean Air Act identifies two types of national ambient air quality standards. Primary standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings. REF:

16 CAA - Terms & Conditions (CONTINUED) National Ambient Air Quality Standards (NAAQS) EPA has set National Ambient Air Quality Standards for six (6) principal pollutants, which are called "criteria" pollutants - listed below. Units of measure for the standards are parts per million (ppm) by volume, parts per billion (ppb) by volume, and micrograms per cubic meter of air (µg/m 3 ) Carbon Monoxide Ozone Lead Particulate Pollution Nitrogen Dioxide Sulfur Dioxide

28 History of Air Pollution Actions in California City of Los Angeles began its air pollution control program Los Angeles County Air Pollution Control District is established. It is the first of its kind in the nation. June 10, 1947, California Governor Earl Warren (R) signs into law the Air Pollution Control Act, authorizing the creation of an Air Pollution Control District in every county of the state California Bureau of Air Sanitation is formed within the State Department of Public Health, and the Bay Area Air Pollution Control District is established. Federal Air Pollution Control Act of 1955 enacted

29 History of Air Pollution Actions in California (CONTINUED) California enacted legislation requiring the state Department of Public Health to establish air quality standards and necessary controls for motor vehicle emissions The California Motor Vehicle Pollution Control Board is established.

California regulations further reduce pollution-causing chemicals from consumer products including: bug sprays and a variety of household and professionally-used cleaners. ARB approves the State s cap-and-trade regulations. ARB makes new changes to diesel regulations for owners of on-road and off-road equipment.

42 California s Air Districts

43 San Joaquin Valley

44 San Joaquin Valley Air Pollution Control District The SJV APCD is made up of eight counties in California s Central Valley: San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare and the San Joaquin Valley Air Basin portion of Kern County. This Air District is governed by an 15-member Governing Board consisting of representatives from the Board of Supervisors of all 8 counties, one Health and Science member, appointed by the Governor, one Physician, appointed by the Governor and five Valley city representatives.

49 SJV APCD OZONE Ozone emissions have been reduced to historically low levels, however, Valley meteorology has become the predominant controlling factor in causing 1-hr ozone exceedances ozone NAAQS - 84 parts per billion 2008 ozone NAAQS - 75 parts per billion Despite significant progress in reducing the Valley s 8-hour ozone Design Value and annual number of exceedances, attaining the NAAQS is proving to be more challenging in the San Joaquin Valley than in any other region in the nation. The enormity of this challenge is primarily due to the Valley s meteorology and topography; which create ideal conditions for generating and trapping ozone. Technology does not currently exist to achieve all emission reductions that are necessary to reach the Federal NAAQS. REF: SJV APCD Annual Report:

59 Human Health Risk Assessments The District s Check Before You Burn program, which is based on District Rule 4901 (Wood Burning Fireplaces and Wood Burning Heaters), has been reducing harmful PM-2.5 s when and where those reductions are most needed: in impacted urbanized areas when the local weather is forecast to hamper PM dispersion. In 2008, the Central Valley Health Policy Institute found that District wood burning curtailments on high pollution days reduced annual exposure by about 13% in Bakersfield and Fresno, resulting in 30 to 70 avoided cases of annual premature mortality.

60 Valley Air Pollution Study Landmark Study Links Air Pollution to Valley Illness The District provided a grant to CSU-Fresno s Central Valley Health Policy Institute and UCSF-Fresno s School of Medicine to conduct an air quality epidemiological study of Valley residents. Using medical records and air quality data for Bakersfield, Fresno, and Modesto, the study examined whether daily emergency room (ER) or hospital admissions for respiratory and cardiovascular diseases rose in relation to increased PM-2.5 or ozone levels. Data on adults and those 19 and younger were examined separately. By looking at daily ER/hospital admission rates following the top 20% most polluted days vs. the cleanest 20% of days, researchers found the following

61 Valley Study (CONTINUED) Compared to winter days with clean air, during the Valley s worst wintertime PM2.5 pollution Youth are: 49% more likely to be admitted to an ER for asthma, and 67% more likely to be admitted to hospitals for asthma. Adults are: 29% more likely to be admitted to an ER for asthma, 80% more likely to be admitted to hospitals for asthma, 28% more likely to be admitted to an ER for acute bronchitis, and 13% more likely to be admitted to hospitals for heart attack. Compared to summer days with clean air, during the Valley s worst summertime ozone pollution Youth are 69% more likely to be admitted to an ER for asthma. REF: SJV APCD Annual Report:

62 Direction of Federal NAAQS and SJV APCD s Response Clearly, the Valley faces unique and significant difficulties in achieving the anticipated NAAQS, which are approaching the Valley s naturally occurring background concentrations. Attainment of the new NAAQS will require transformative, new air pollution controls, including zero-emission technologies, alternatives to long-practiced development patterns and transportation systems, and perhaps even the elimination of fossil-fuel combustion in the Valley. REF: SJV APCD Annual Report:

63 In Summary The Federal Clean Air Act (CAA) is the most significant and furthest reaching of any environmental regulation to date. The CAA will affect. Where we live/work, How we live/work, What we can (or cannot) buy, The price we pay for commodities, and The taxes (they call them fees ) we will pay. RESULT.Higher prices and limited choices.

64 In Summary Given history of the EPA to reduce NAAQS, coupled with the arid southwest, coupled with the topography and meteorology of the San Joaquin Valley The SJV may not meet NAAQS attainment unless. Soil is not disturbed Fossil-fuel combustion ceases Dairies, farms and ranches cease to operate All roads are closed to automobile and truck traffic Then, maybe just maybe, the San Joaquin Valley might be a healthy place to live.
