Summary
The
Office of the Inspector General, at the request the Glynn Environmental
Coalition, has reviewed claims that a
Glynn County, GA Superfund site
contaminated with Toxaphene is receiving inadequate clean up. At the heart
of
the dispute is a testing method that fails to detect most of the toxic congeners and degradation products of toxaphene,
thus underestimating the
extent of contamination. Use of the biased testing method was approved by a
closed partnership
between EPA Region 4, the Georgia Environmental
Protection Division (GaEPD) and Hercules, Inc. that failed to include
community representatives. Both the OIG and a previous review by the Agency
for Toxic Substances and Disease Registry
(2002), have recommended that EPA
should discard this flawed method in favor of established tests that
identify toxaphene
degradation products.
The
Glynn County contaminated sites, predominately populated by low-income
African-American families, provide EPA
with an immediate opportunity to work
with the community, apply appropriate scientific methods, and force the
stringent
clean up that was promised to the community over two decades ago
when this site was listed as a National Priority Superfund site.
History of the site[3]: twenty years is too long
Hercules Inc., a former pesticide
plant, manufactured toxaphene as an insecticide at its plant in the city of
Brunswick,
Glynn County, Georgia, from 1948 to 1980. In these comments, we
will use the term “polychlorinated camphene”
(PCC) to describe toxaphene, a
mixture of over 670 chemicals of concern, and its residues and conversion
products.
The Hercules 009 Landfill Superfund
Site in the city of
Brunswick, in Glynn County, Georgia operated from 1975 until 1980,
and was
listed on the National Priorities List (NPL) in 1984, over 20 years ago[4].
The Brunswick area has a commercial
fishing port and a thriving seafood
industry, as well as recreational fishing and crabbing. 9
The Hercules 009 Landfill is described
as a 16.5 acre property that is bordered by Georgia State Highway 25 on the
west;
an automobile dealership on the north; a juvenile slash pine forest on
the east; and several homes, a church, a school, and a
strip shopping center
to the south/southeast of the property.[5]
Until required by the Clean Water Act
to treat waste water in 1972, Hercules reportedly released up to 200-300
pounds of
PCC per day as waste water,[6]
ranged from 2,332 parts per billion (ppb) in 1970 to 6.4 ppb in 1974.[7]
PCC has been
reported at levels exceeding 15,000 parts per million (ppm) at
the Hercules 009 Landfill Site.[8]
In 1976 PCC discharge
was restricted to a daily maximum of 1 pound per day
and a daily average of 0.5 pounds per day. Subsequent discharge
was limited
to 0.00081 ppm, though violations were recorded.[9]
In July 1988, Hercules
and EPA entered into an Administrative Order on Consent for conducting a
remedial investigation/feasibility
study (RI/FS)[10]
to assess the risk to human and environmental health and evaluate treatment
approaches.[11]
In 2002, the Agency for Toxic
Substances and Disease Registry (ATSDR), an agency of the U.S. Department of
Health and
Human Services, conducted a public health assessment of some of
the Hercules waste areas in
Brunswick.[12]
In that report,
ATSDR recommended limiting consumption of fish from the
contaminated areas.
Both the ATSDR and the Office of the
Inspector General (OIG) specifically identified the method advocated by EPA
Region 4
and Hercules as insensitive, inadequate, and likely to
significantly underestimate contamination levels, and instead recommended
the use of pre-validated and scientifically accepted measurement methods.
[13]
[14]
Current clean up issues: intentionally insensitive methods fail to detect
contamination
The Hercules Landfill Superfund Site
and five other sites contaminated by PCC in
Glynn
County, Georgia are slated for a
sub-standard clean up that will leave at
risk the community and the environment. This is being pushed through because
of a
closed partnership between EPA Region 4 and Hercules that excluded
community participation. This pairing of between state
regulators and the
regulated industry was self-titled the Toxaphene Task Force. Among numerous
biased and discredited
pronouncements of this task force was use of a
measurement method that failed to detect most of the over 600 congeners,
residues, and degradation products of PCC contamination. The Region 4
assessment, relying on the flawed method, was
strongly criticized by the ATSDR in a 2002 report as underestimating the exposure.[15]
The OIG specifically noted that
the methods used by Region 4 and Hercules
are not designed to measure toxaphene degradation products, and instead
recommended established testing methods that specifically test for toxaphene degradates.[16]
The stubborn insistence by Region 4 to
continue to rely on a biased and unscientific method that has been rejected
by the
ATSDR and the OIG can cynically be viewed as a blind, ideological
adherence to fiction in the face of facts. The result of
these actions,
whether ignorant or intentional, is a failure to provide the protection for
human and environmental health that
is promised in the mission[17]
of the EPA.
Hazard information: Toxaphene is persistent, bioaccumulative, and banned
Toxaphene is a toxic
chlorinated-hydrocarbon persistent bioaccumulative banned pesticide. It is a
mixture of over 670 chemicals
of concern, and is approximately 40 to 75%
chlorine by weight. In 1982 toxaphene was restricted in the
US,
and then fully
banned in 1990. Although it has low solubility in water, it
is readily adsorbed in soil and sediments, and bioconcentrates in aquatic
organisms including fish. It is highly acutely toxic to fish, even at
concentrations that are low parts per billion (ppb; one ppb is one
part in
109, or roughly a drop in an Olympic-sized swimming pool) or high
parts per trillion (ppt; one ppt is one part in 1012, or
roughly
one second in 320 centuries).[18]
[19]
[20]
In
its 2002 report of the
Brunswick
area, ATSDR described the relevant toxicity literature. Animal testing that
pre-birth and
post-natal exposure to toxaphene may interfere with normal
development.[21]
When pregnant rats were fed a diet contaminated
with toxaphene, effects
included poor righting ability and poor swimming ability, compared with
healthy control animals.[22]
The exposed rats eventually attained normal swimming ability. ATSDR also
noted that, “when the rats took a maze test at the age
of 70 days, those
previously exposed to PCC components had difficulty remembering the path
leading to the food”. ATSDR
recommended that, “pregnant women and nursing
mothers should avoid consuming large quantities of contaminated fish and,
obviously, avoid ingesting contaminated soil” to protect the developing
fetus and child. ATSDR warned that exposure to PCC
through contaminated fish
and surface soils, should also be minimized in infants and young children.[23]
Air exposures should
also be considered hazardous; PCC is up to 8% in soils
at the Hercules Plant.
National interest: a bad job here may lead to failed clean-ups nationally
NPL sites are the most serious sites
across the country, slated for possible long-term cleanup by EPA's Superfund
program.
Altogether, there are 1,246 final sites across the country, of
which 18 sites across 9 states include toxaphene as a contaminant.[24]
Therefore, the level of clean up that EPA will require at this site is
likely to impact requirements across the country.
The document record is clear that it is
the intention of Hercules to submit its toxaphene review to the EPA
database, the Integrated
Risk Information System (IRIS),
which contains
EPA’s scientific positions on potential human health effects from
environmental
contaminants. While not an enforceable regulatory standard
per se, information on IRIS is
considered by
regulators at the state and
federal level and others worldwide to set
pollution cleanup standards and various exposure standards for air, water,
and soil.
Hercules advocated a reduction in the
cancer potency factor 10-fold on the IRIS database[25]
from 1.1 mg/kg/day to 0.11
mg/kg/day, and stated that it has already gone so
far as to submit its proposed factor to Office of Solid Waste and Emergency
Response (USEPA/OSWER), based on “new information”[26]
citing a 1998 report. This would likely severely impair clean-up
action at
contaminated sites all over the country.
In addition to weakening the cancer
potency factor, Hercules also proposed to weaken the non-cancer “safe”
level, known as
a Reference Dose (RfD), posted on the IRIS database. In its
comments to ATSDR, Hercules states that it has submitted an
alternative RfD
of 0.0007 mg/kg/day for the IRIS database.[27]
This is approximately 3-fold more permissive than the old IRIS
RfD of
0.00025 mg/kg/day (IRIS, 1993), which has now been removed from the IRIS
database. Hercules specifically notes that
use of its alternate RfD value
would raise the screening level from 3 ppm to 7.5 ppm toxaphene in fish.[28]
It should be extremely concerning to
taxpayers that a scientific article that proposes to disregard all but a
handful of PCC congeners
is co-authored by scientists from EPA Region 4 and
the Georgia Environmental Protection Division (Simon and Manning, 2006).
Though no source of funding is disclosed, it is published in a journal,
Regulatory Toxicology and Pharmacology, well-known to
be biased towards
industry perspectives. In fact, in 2002 the journal was targeted in a letter
by over forty scientists, including noted
international experts and journal
editors, citing concerns about, “apparent conflicts of interest, lack of
transparency, and the absence
of editorial independence”.[29]
Specifically, their letter cites, “the journal’s apparent bias in favor of
industries that are subject to
governmental health and environmental
regulations”. The letter goes on to identify financial supporters of the
journal sponsor, including,
the American Chemistry Council, Dow AgroSciences,
R.J. Reynolds Tobacco Co., and others. Moreover, the letter identified a
“significant percentage” of the editorial board with financial ties to
companies whose products are the subjects of studies published in
the
journal. Is it any wonder, then, that this article advocating a weakening of
cancer potency of toxaphene found its way to this journal?
But, the fact
that the authors are public employees suggests a disconcerting level of
partnership between Hercules and the regulatory agencies.
Environmental Justice: EPA fails to act on Executive Order 12898
The
State and Federal agencies charged with the protection of human and
environmental health are faced with a moral test of
deciding whether to
unfairly burden
Glynn
County families with health risks that they are not likely to bear
themselves, and that
are not shared equally across the nation.
Glynn
County is comprised of 72% white population and 26.5% black population, more
diverse than the National average of
80% white and 13% black (2004 Census
data).[30]
However, the
Brunswick
city has a total population of approximately
15,600 people, of which 36% are
white and 60% are black (2000 Census data as reported by ATSDR).[31]

county has approximately 27,000 households (2000 data), with a median
household income of $38,600, less than the
National median of $43,300 (2003 data). However,
Brunswick
City has a median household income of only $22,200
(2000 data), much lower
than the county and national. This leaves 15% of
Glynn
County residents living below poverty
(2003 data), more than the National
average of 12.5%. However, 30% of Brunswick City residents live below
poverty
(2000 census data). In summary, Glynn County residents are more
likely to be black and/or to be poor than the average
American.
In
addition to the Hercules 009 Superfund site, the Brunswick area is the site
of two additional industrial facilities that have
been classified as
Superfund sites, and 17 other potentially hazardous waste sites.[36]
Maybe the unfair distribution of toxic
dump sites and other industrial
facilities is a significant factor in the higher rate of cancer and other
diseases among black residents
compared with white residents of Glynn
County. In the health service area that extends from Duval County
(Jacksonville) FL to
Glynn County GA, EPA reports that the overall cancer
rate per 100,000 population is 177 for white males compared with 257.7
for
black males.[37]
The cancer rate for white females is 118.4, compared with 135.1 for black
females. Childhood leukemia
rates are almost 2-fold higher for black males
(14.1 per 100,000), compared with white males (8.9 per 100,000);[38]
data for
females is similar for white (6.1) and black (4.9) populations.
The
EPA provides a description of environmental justice on its website:
Environmental Justice is the fair
treatment and meaningful involvement of all people regardless of race,
color, national origin,
or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.
EPA has this goal for all communities and persons across this
Nation. It will be achieved when everyone enjoys the same
degree of
protection from environmental and health hazards and equal access to the
decision-making process to have a healthy
environment in which to live,
learn, and work.[39]
Despite this laudable and critical recognition of the unfair distribution of
risk and disease across this country, a study just released
in September
2006 by the Office of the Inspector General is highly critical of EPA’s
failed record on taking action to correct these
injustices.[40]
The IG recommended that EPA review its programs appropriately and take
action consistent with Executive Order
12898 to address the unfair impact of
industrial waste on communities.[41]
Take
action now to protect human health
We
generally support the OIG reports, and encourage the OIG to issue a strong
response to EPA to work with the community,
apply appropriate scientific
methods, and force the stringent clean up that was promised to the community
over two decades
ago when this site, predominately populated by low-income African-American
families, was listed as a National Priority
Superfund site.

ATSDR report (2002) Appendix F: Response to comments. ATSDR states, “On
April 14, 2000, ATSDR formally received an analytical protocol from USEPA, Region IV describing the "Procedures for the Determination of
Toxaphene," a three-page protocol dated August 14, 1997. This protocol,
which was intended to be used by USEPA-Region IV and Hercules, employed
"the last four to seven peaks in the 'back half' of the toxaphene
chromatogram for calibration and quantification of toxaphene."
The "four
peak in the back half" methods dates to the packed column days, when
there were only several usable peaks shown on the back half of toxaphene
chromatogram (USEPA 1986 Method 8080). This "four-peaks-in-back- half"
method was precise at that time... This method, however, has lost its
precision now because the powerful capillary column in modern gas
chromatography instruments generates dozens of peaks in the back half of
the chromatogram of toxaphene standard... Although the Method 8081A of
January 1995 kept this "four-peaks-in-back- half" method, the method was
purged from the official December 1996 version of Method 8081 A, as well
as the new Method 8081 B of January 1998. Recently, GA EPD repeated the
analysis of 56 samples from the old April 1997 samples with the specific
methodology of both GC-ECD and GC-MS at Skidaway Institute of
Oceanography.
On June 19, 2000, quantitative data for the 56 samples
became available and the PCC concentrations up to 26 ppm was found in
fin fish. This work was published in peer reviewed, open literature in
September 2001.”
