3Case 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
childrens 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 refineries.
4General Description of Oil Refineries
- Purpose
- Oil refineries are complex process plants which
turn crude oil into a range of products,
including petroleum.
5Crude Oil
- Crude Oil is unprocessed oil.
-
- It is derived from decaying animal and plants
which lived millions of years ago.
6Crude Oil Hydrocarbons
- Crude oil contains hydrocarbons and form
different classes including
- - Paraffins
- - Aromatics
- - Napthenes or Cycloalkanes
- - Alkenes Dienes and Alkynes

8Refineries Perform 3 Basic Steps
- 1) distillation separates the complex mixture
of hydrocarbons in crude oil into components.
9Refineries 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
10Refineries 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.
11Function 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
asphalt
- 3) chemical industry feed stocks such as benzene
and propane
12Problems of Oil Refineries
- Toxic Pollutants of Oil Refineries and its effect
on Air Pollution
- 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.
13Problems 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.
14Problems of Oil Refineries
15Problems of Oil Refineries
- Oil refineries are responsible in allowing
hazardous toxins, otherwise know as fugitive
emissions to be emitted into the local and global
community. - 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).
16Problems 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
- tanks.
- 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
17Locations 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).
18Public 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)
19Public 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
20Public 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. -
21Public Health Issues
- Children, the elderly, and people with
respiratory conditions, including asthma are
especially susceptible to ozone pollution.
22Asthma
- Asthma is a chronic inflammatory disease of
the airways.
23(No Transcript)
24Asthma
- Asthma is a growing epidemic with the rate
of Americans suffering from asthma being doubled
in the last fifteen years, 1980-1996.
-
- (Department of
Health and Human Services, 2002).
25Asthma
- 9 million children are affected by asthma.
(Pudget Sound Clean Air Agency, 2002)
26Asthma
- - 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
27Asthma
- 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
disease. -
(Pudget Sound Clean Air Agency, 2002).
28Asthma
- Exacerbations can be triggered by exposures
and conditions such as outdoor air pollutants.
(Department of Health and Human Services, 2002).
29Serious 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).
30Social 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
- annually.
-
-
(American Lung Association)
31Social 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)
32Social Impacts of Asthma
- Disproportionate Burden of Asthma in Minority
Populations and Those Living in Poverty.
33Social 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).
34Social 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
35Environmental 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).

- 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). -
