   Case Study: Oil Refineries in
      Contra Costa County
   This presentation focuses on the emissions of
pollutants from oil refineries, with Contra Costa County
as a case study, and how the noxious wastes affects the
high level of children’s asthma.
   Furthermore the presentation is designed to describe
how toxins from oil refineries effects the public health of
the surrounding community.
    The presentation will analyze and describe the
purpose, function, problems, and locations of oil
refineries in Contra Costa County.
   Moreover it pays particular attention to the social,
environmental, and public health impacts of the process
associated with the emissions of toxins from oil
      General Description of Oil
• Purpose:
  – Oil refineries are complex process plants which turn
    crude oil into a range of products, including
                Crude Oil
“Crude Oil” is
unprocessed oil.

It is derived from
decaying animal and
plants which lived
millions of years ago.
    Crude Oil & Hydrocarbons
Crude oil contains hydrocarbons and form different
  classes including:
  - Paraffins
  - Aromatics
  - Napthenes or Cycloalkanes
  - Alkenes Dienes and Alkynes
 Refineries Perform 3 Basic Steps
1) distillation: separates the complex mixture of
    hydrocarbons in crude oil into components.
 Refineries Perform 3 Basic Steps

2) conversion: splits or re-forms the
    backbone of carbon atoms in a
    hydrocarbon molecule in order to make
    new components of higher value
  Refineries Perform 3 Basic Steps

3) Treating: substitutes hydrogen atoms for
    sulphur atoms in the hydrocarbons, thereby
    reducing the pollution caused when the ultimate
    products are burned
      - followed by blending together of the resulting
      components to make finished products.
  Function of Oil Refineries
1) use physical, thermal, and chemical
    separation techniques to separate crude oil
    into several components, including fuel
2) non-fuel products such as solvents and
3) chemical industry feed stocks such as
    benzene and propane
        Problems of Oil Refineries

•   Toxic Pollutants of Oil Refineries and its effect on Air
    –   Oil refineries are one of the largest sources of air pollution in
        the Unites States
    –   Refineries are the fourth largest industrial source of toxic
        emissions and the single largest industrial source of benzene
        emissions, a known human carcinogen.
    Problems of Oil Refineries
2)Emissions of volatile organic compounds (VOCs).

   a) Refineries are the single largest stationary source of
   volatile organic compounds (VOCs), the primary
   precursor of urban smog.

    b) refineries release approximately 492 million pounds
    of VOCs each year.

   c) oil refineries release more than twice as many VOCs
   as the next highest sector, organic chemical plants.
Problems of Oil Refineries
    Problems of Oil Refineries

Oil refineries are responsible in allowing hazardous toxins, otherwise
   know as fugitive emissions to be emitted into the local and global
         a) oil refineries vastly underreport leaks from valves to
            federal and state regulators

        b) these unreported fugitive emissions from oil refineries add
           millions of pounds of harmful pollutants to the atmosphere
           each year, including over 80 million pounds of volatile
           organic compounds (VOCs) and over 15 million pounds of
           toxic pollutants (Waxman, 1999).
  Problems of Oil Refineries
Furthermore if these industries complied with Clean Air
 Act, much of the pollution would be eliminated.
   c) Fugitive emissions come from a number of
      sources, including leaking valves, pumps, seals,
      connectors, pressure relief devices, and storage
   d) The majority of toxic pollutants from oil refineries
      are released a fugitive emissions. According to
      TRI data, rep oil refineries reported releasing 31
      million pounds of toxic fugitive emissions in 1997,
      more than half of the 58.7 million pounds of toxic
      air pollutants released
    Locations of Oil Refineries

United States oil refineries are located in:
 - Texas:         27 refineries
 - California:     24 refineries
 - Louisiana:     20 refineries
 - Pennsylvania: 6 refineries
 - New Jersey: 6 refineries
 - Illinois:       6 refineries
                                       (Waxman, 1999).
Public Health Issues
          • Air pollutants are considered
            “toxic” when they have the
            potential to cause serious
            adverse health effects, such as
            cancer, neurotoxicity, or
            reproductive toxicity.
          • Examples of these toxic air
            pollutants include benzene, a
            known human carcinogen, and
            xylenes, which depress the
            central nervous system,
            damage the kidneys, and
            irritate the respiratory system.
            (Waxman, 2000)
      Public Health Issues
Refineries are the single largest stationary
source of VOCs, the primary precursor
of urban smog.

Ground level ozone, a toxic gas that is the
primary ingredient of urban smog, is
formed when emissions of VOCs react
with nitrogen oxide (NOx) emissions in
the presence of sunlight
       Public Health Issues

High levels of smog have been linked to serious
health problems, including irritation of the
respiratory system. Smog also aggravates
preexisting respiratory diseases such as asthma.
       Public Health Issues
Children, the elderly,
and people with
respiratory conditions,
including asthma are
especially susceptible
to ozone pollution.

Asthma is a chronic inflammatory disease of
the airways.
Asthma is a growing epidemic with the
rate of Americans suffering from asthma
being doubled in the last fifteen years,

               (Department of Health and Human Services, 2002).
• 9 million children are affected by asthma.
  (Pudget Sound Clean Air Agency, 2002)

- Asthma sufferers feel
    their lungs constrict
       and experience,
   each new breath as
     if drawn through a
        narrow straw.

 - Asthma is the most
     prevalent chronic
      disease among
   children in California
 According to a California study,
researchers show that children who
breathe heavily polluted air are more
likely to develop asthma.
 •   The study reports, “the strongest evidence yet
     that smog can not only aggravate existing
     childhood asthma, which has reached epidemic
     proportions among American youth, but may
     actually be one cause of the life-threatening
                         (Pudget Sound Clean Air Agency, 2002).

Exacerbations can be triggered by exposures
and conditions such as … outdoor air
pollutants.” (Department of Health and Human
Services, 2002).
Serious Health Impacts of Asthma

Asthma is a potentially fatal, chronic
disease responsible for over 1.8 million
emergency room visits per year, over 460
thousand hospitalizations per year and
over five thousand deaths per year

              (Department of Health and Human Services, 2002).
Social Impacts of Pediatric Asthma
                   Besides health impacts
                   on children there are
                   many social impacts that
                   affect asthmatic children.
                     1) School Absenteeism
                        a) Asthma accounts
                         for 14 million lost
                         school days

                             (American Lung Association)
Social Impacts of Pediatric Asthma

Millions of lost hours at work for parents who must nurse
 sick kids.

The estimated annual cost of treating asthma in those
 under 18 years of age is $3.2 billion. (American Lung Association)
   Social Impacts of Asthma
Burden of Asthma in
Minority Populations
and Those Living in
    Social Impacts of Asthma
• Although asthma affects Americans of all
  ages, races and ethnic groups, recent data
  indicate that children, low-income and
  minority populations have been most
  severely affected

               (Department of Health and Human Services, 2000).
   Social Impacts of Asthma
The reasons for the disparities are due to
interaction of factors including: lack of
access to quality medical care, high levels
of exposure to environmental allergens
and irritants, language barriers, and lack of
financial resources and social support to
manage the disease effectively on a long-
term basis
    Environmental Injustices
Environmental racism and environmental
inequity are, “…evidence that
environmental hazards are not distributed
equally among various groups of people, either
in the United States or throughout the world.
Instead, communities of color and to lesser
extent, poor people in general are exposed to
hazardous and toxic wastes, dangerous working
conditions, polluted air and water, and other
environmental insults to a greater degree than
are non-colored communities and people of
higher incomes.”                     (Newton, 1996).

  A Case Study of Contra Costa
   County and Richmond, CA
Since 1989, there have been 35 major industrial
accidents in Contra Costa County, California, making it
one of the most dangerous places to live in the nation.
(University of Michigan).

Between 1989 and 1995, there were over 1900 different
incidents reported in the county, making it the eleventh
worst area in the entire United States with regards to
toxic accidents (University of Michigan).

Chevron had 304 accidents between 1989 and 1995 --
major fires, spills, leaks, explosions, toxic gas releases,
flaring, and air contamination (University of Michigan).
