EPA AND REGISTRANTS IN DINOSEB HEARING REACH
CANCELLATION SETTLEMENT
EPA and the remaininq registrants in the dinoseb	A1 Heier
pesticide cancellation hearing proceedings, Cedar	202-382-4374
Chemical Corp. and Drexel Chemical Co., have reached
a settlement which is expected to result in final
cancellation of all remaininq dinoseb registrations.
EPA and the registrants have submitted a joint motion
to the Administrative Law Judge requesting that
the settlement be implemented and that the cancel-
lation hearinq be terminated. The settlement includes
provisions that will permit temporary use under
stringent restrictions of remaining stocks of certain
dinoseb products on certain crops in certain states.
Under EPA regulations, other parties in the proceeding
will have 10 days to respond to the motion, and the
Administrative Law Judqe will then reach a decision
on implementation of the settlement agreement and
submit that decision to the EPA Administrator for
final determination. The Administrator has up to 90
days to issue a final order in the case.
Under provisions of the settlement, EPA would permit
existinq stocks of cancelled dinoseb to be distributed,
sold and used: 1) for weed control in dry peas, lentils,
chickpeas and qreen peas in the states of Washington,
Idaho and Oregon during the 1988 use season; and 2) for
vegetative cane control in caneberries (blackberries,
boysenberries, loganberries and raspberries) in the
states of Washington and Oregon during the 1988 and
1989 use seasons. Distribution, sale and use of dinoseb
will only be authorized for a particular crop in a
particular state if its state department of agriculture
expressly requests such authorization and agrees to
enforce the restrictions the final order would impose.
The proposed restrictions included in the proposed
cancellation order are stringent and detailed to
minimize the exposure and risk associated

with any further dinoseb use. EPA estimates that
up to 285,000 gallons of existing stocks may be
utilized under these provisions. Over two million
gallons of other remaining stocks of dinoseb,
labeled primarily for use on peanuts and soybeans,
have been reported to EPA by registrants and dealers.
The settlement agreement includes provisions intended
to establish the amount of indemnification that
the registrants are entitled to receive under the
Federal Insecticide, Fungicide and Rodenticide Act
(FIFRA). In the settlement agreement, EPA also agrees
to accept eligible dinoseb products for federal
disposal under FIFRA as soon as practicable, but no
later than Dec. 31, 1988. However, EPA will only be
able to meet this deadline if it receives adequate
funding for this purpose.
EPA issued a notice of intent to cancel the dinoseb
registration and an emergency order immediately
suspending all further distribution, sale and use of
pesticide products containing dinoseb in October
1986. These actions were based on the agency's
determination that continued use of dinoseb products
would pose an unacceptable risk of birth defects,
male reproductive effects and acute toxicity for
pesticide applicators and agricultural workers.
Emergency suspension of the sale, distribution and
use of pesticide products is the most stringent
action available to EPA under FIFRA and has been
exercised on only three previous occasions. The
notice of intent to cancel dinoseb was challenged
by Drexel and Cedar and acceptance of this agree-
ment by the Administrator will end the cancellation
proceedings.
MEYERS, LONG AND GUIMOND NAMED TO NEW POSITIONS

DELONGHI CONSENT AGREEMENT FILED
A consent aqreement between EPA and DeLonghi America Inc. Alicia Tenuta
was filed with the Chief Judicial Officer on Dec. 21.	202-382-4132
The aqency filed a $1.5 million complaint against the
company in 1986, alleging illegal importation and sub-
sequent export of a number of PCB-contaiminated oil-filled
radiator heaters. The consent agreement requires payment
of a $520,000 civil penalty. The agreement also requires
the establishment of a $200,000 "starter fund" for
handlinq return, replacement and disposal of contami-
nated heaters, testing and certification of all heaters
entering the U.S. and a consumer awareness program.
MIDWEST DEVELOPERS PENALIZED FOR WETLANDS DESTRUCTION
In the first use of administrative penalties for wetlands
violations under the Clean Water Act, EPA Region 5 in
Chicaqo has proposed administrative penalties against two
developers in Illinois and one in Minnesota for destroying
separate wetland areas. Administrative penalties were
first authorized by Congress in the 1987 Amendments to
the Clean Water Act and allow EPA to bypass the court
system and penalize companies directly. The three deve-
lopers and communities in which the violations took place
are Kirk Corporation, Streamwood, 111; Hoffman Group,
Hoffman Estates, 111.; and Woodland Development Corp.
Andover, Minn. Kirk allegedly filled in one acre of an
IB-acre wetland site and is being assessed with a proposed
penalty of $15,000. Woodland allegedly filled in 22
acres to develop a golf course and housing project and
may be required to pay $75,000. Hoffman allegedly filled
in six acres and may pay a $125,000 penalty. The developers
have 20 days to respond to the complaints.
MERCEDES-BEN2 PENALIZED FOR CLEAN AIR VIOLATIONS
Mercedes-Benz of North America Inc. and Daimler-	Martha Casey
Benz Aktiengesellschaft have agreed to pay a	202-382-4378
$148,000 civil penalty to settle alleged
violations of the Clean Air Act reporting require-
ments. The alleged violations include failure to
describe an emission-related part in the application
for certification and failure to update the application.
The aqency said the auto manufacturer also failed to
report changes to parts on its vehicles and to report
an emission-related defect as well as numerous main-
tenance tests on certification test vehicles. The
alleged violations occurred during the 1981 through
1986 model years. EPA relies, in part, on infor-

mation submitted by automobile manufacturers to
determine whether their motor vehicles comply with
the emission standards. As part of the settlement,
Mercedes-Benz also aqreed to devise and implement
compliance and employee education programs to prevent
similar situations from occurring.
EPA EXECUTIVES RECEIVE PRESIDENTIAL RANK AWARDS
Three EPA executives were among those career	Dave Ryan
government officials whose accomplishments were	202-382-2981
recognized by the 1987 Presidential Rank Awards.
Michael B. Cook, Director of the Office of Drinking
Water in the Office of Water, has reoriented the
drinking water program under the far-reaching Safe
Drinking Water Amendments of 1986; worked inten-
sively with congressional staff on the Hazardous
and Solid Waste Act of 1984 to improve the work-
ability and practicality of the amendments; and
established EPA policies, priorities, and mecha-
nisms to cope with these new requirements.
Rebecca W. Hanmer, Deputy Assistant Administrator
for Water, has been instrumental in recognizing
the expense and complexity of regulating toxic
entering the nation's waters and encouraging use
of more reliable, less expensive, b iomoni tor i ng
techniques; in negotiating with Congress as it
reauthorized the Clean Water Act; and in imple-
menting the pretreatment program for toxic control.
Alexandra B. Smith, Deputy Regional Administrator
for EPA Region 8, has played the lead role in
revamping and clarifying the relationships between
headquarters and regional offices for the pesticides
and toxic programs. From 1975-79, she helped
negotiate environmentally acceptable agreements
with the firms that developed and built the
Alaskan oil piplines. From 1979-84, she served as
deputy and then director of the air and waste manage-
ment division for Region 10 in Seattle.
NEW REGULATORY PRIORITY LIST FOR DRINKING WATER
CONTAMINANTS ANNOUNCED
EPA has announced a final action establishing a new	Dave Ryan
regulatory priority list of 53 drinking water con-	202-382-2981
taminants. EPA must regulate at least 25 contaminants
from this list within three years, as required by the
June 1986 Amendments to the Safe Drinking Water Act. In

addition, a new priority list must be published every
three years, and EPA must requlate a minimum of 53
contaminants from each new list every three years.
This list is in addition to an earlier requlatory
priority list--also required by the 1986 Amendments--
of 83 specified contaminants that must all be regulated
by June 1989 (The list of 83 includes 34 final standards
already set by EPA since the drinking water requlatory
program began in 1975). Today's announced action also
removes seven unregulated drinking water contaminants
from the priority list of 83 and substitutes seven
others in their place, as allowed by Congress in the
1986 Amendments. Congress requires, however, that
regulation of any substitute contaminants has to be
more protective of public health than would be regu-
lation of the contaminants removed from the list. The
seven contaminants EPA is removing from the list are
molybdenum, vanadium, dibromomethane, sodium, zinc,
silver and aluminum. The seven substituted are nitrite,
heptachlor, heptachlor epoxide, ethylbenzene, styrene,
aldicarb sulfoxide and aldicarb sulfone) . The seven
contaminants removed from the priority list of 83
are being placed on this new priority list of 53 for
reconsideration, as required by the Amendments. This
final action will appear soon in the Federal Register.
FEDERAL AGENCIES TO DISCLOSE HAZARDOUS-
SUBSTANCE ACTIVITY IN PROPERTY SALES
EPA has proposed requirements for federal agencies to	Robin Woods
disclose to purchasers information on the storage,	202-382-4377
release and disposal of hazardous substances on federally-
owned property when the property is sold or transferred.
The disclosure must be provided with the sales or transfer
contract. In addition, under the Superfund law, federal
agencies are required to state that all necessary remedial
action as a result of hazardous-substance activity has
been taken prior to the sale and that any future action
found necessary will be conducted by the federal agency.
Under the proposal, certain types of residential property
would be excluded. Also proposed are a storage reporting
level and a notice form. The proposal was published in
the Federal Register on Jan. 13. EPA is providing a
30-day public-comment period.
NEW CLEAN AIR RULES FOR SURFACE COATING
OF PLASTIC PARTS FOR BUSINESS MACHINES
The EPA Admi nistrator on Jan. 12 signed and sent to the	Christian Rice

coating of plastic parts for business machines. Spray
booths at an estimated 200 new, modified and recon-
structed plants will become affected by 1990, reducing
VOC emissions by approximately 2,400 tons per year.
This represents a 51-percent reduction below baseline
from total emissions from these facilities.
SAB MEETINGS SCHEDULED

EPA DEFERS
IMPLEMENTATION OF
PESTICIDE PROGRAM
TO PROTECT
ENDANGERED SPECIES
The U.S. Environmental Protection Agency announced
today that it is deferring implementation of its
pesticide program to protect endangered species until
the 1989 growing season.
The agency had considered implementing the plan
beginning in February 1988, but decided more time was
needed to develop an effective program.
In a Jan. 5 letter to the state commissioners of
agriculture, EPA's Assistant Administrator for
Pesticides and Toxic Substances, Dr. Jack Moore, pointed
out that recent meetings held with the U.S. Departments
of Agriculture and Interior, with state pest-control
officials and others revealed the consistent assessment
that basic elements of the endangered species program
were not sufficiently developed to begin the program
before the 1988 growing season as had originally been
planned.
Dr. Moore also said in the letter, "This decision
to defer the implementation phase and spend additional
time on plan development and communication with all
affected parties is in keeping with a recent
Congressional action that enjoins EPA to work with the
states and not seek to enforce the labeling program
before Sept. 15, 1988."
EPA's Office of Pesticide Programs has been working
for the past several years to strengthen its program to
protect endangered species as required by the Endangered
Species Act, which is administered by the Fish and
Wildlife Service (FWS) of the Department of Interior.
The Act states that actions authorized, funded or
carried out by any federal agency must not jeopardize
the existence of endangered species. The registration
R-4

of pesticides is considered an authorization for use, and thus is subject
to the Endangered Species Act.
Endangered species have been identified by FWS as being potentially
jeopardized by pesticide use in approximately 910 of 3,050 counties in the
United States. The current EPA program would have affected approximately
110 active ingredients in pesticide products. EPA1s original implementation
plan called for product labels to include a list of states and counties
containing endangered species potentially affected by certain pesticides.
The labels would refer users to county bulletins for further information
on the applicable restrictions on pesticide use. The bulletins would be
available in county agricultural extension offices as well as in places
where pesticides are sold.
EPA's endangered species original plan addresses pesticides in clusters
according to registered use including forestry, cropland, mosquito larvae
control and eradication, range and pastureland, non-cropland, alfalfa and
associated hays, aquatic herbicides and rice. Implementation of all clusters
has been deferred.
"During the coming year we will be working closely with each state to
customize this program to fit its needs," Dr. Moore stated. "We want to
ensure that the program is based upon accurate and practical information,
and that we take the time to obtain input from all affected groups."
Moore added, "I would hope that pesticide users will act voluntarily
to protect endangered species from pesticides while EPA works to develp a
program for 1989."
During 1988, EPA will be engaged in a number of activities to prepare
for implementation in 1989. EPA intends to solicit suggestions for revisions
to the program from the public, conduct a broad public-education effort,
refine the scientific data supporting the program and work with involved
federal and state state agencies.
"We believe this initial delay will ultimately result in improved
protection for endangered species. It will help us to develop a solid,
workable program for the long run. The goal of our efforts remains to
protect endangered species while at the same time avoid any unnecessary
disruption of agriculture or other uses," Moore continued.
Several states have informed EPA that they intend to develop state-
initiated plans, which will recommend alternative measures to protect
endangered species from pesticide use. These states have been asked to
submit their work plans to EPA by February 1988 and then to develop and
refine their plans later in the year.

CYANAZINE AS A
CONDITION FOR
CONTINUED
rh:g i strat ton
The U.S. Environmental Protection Agency is
requiring that risk-reduction measures he added to the
product labels of the pesticide cyanazine as a condition
for continued sale and use after determining that
exposure may result in unreasonable risk to persons
mixing, loading and applying this chemical.
Cyanazine (trade name Bladex®) is a pre- and
post-emergent herbicide used to control annual grasses
and broad leaf weeds.
EPA's action is based on animal studies which
showed that exposure to cyanazine caused birth defects
and may pose a significant risk to women of childbearing
aqe who handle this product. EPA's principal concerns
are risks to mixers, loaders and applicators resulting
from dermal exposure to this chemical. The risk from
dietary exposure to cyanazine is not considered to be
significant at this time.
Today's action reguires that the following use
modifications be included on cyanazine product labels:
the use of protective gloves for mixers and loaders (also
includes applicators associated with qround-boom
operation) and for adjusting, repairing or cleaning
equipment used with cyanazine; the use of a chemical-
resistant apron when mixina and loading cyanazine; and
the use of a closer] loading system when applying
cyanazine through aerial or cheTnigation methods (the
chemical is added in the process of irrigation). Pro-
duct formulations which cannot be used in a closed
loading system (i.e., wettable powder and granular
formulations) must prohibit aerial use and chemiqation
on their labels.

EPA EXTENDS	The U.S. Environmental Protection Agency announced
INTERIM
CERTIFICATION	today that it is extending through Dec. 31, 1988, the
PROGRAM ON
GRAPES	interim certification policy regarding the use of
sulfur dioxide pesticides (sulfites) on grapes. Under
this program, grapes imported or shipped in interstate
commerce must be certified to contain no detectable
residues of sulfites (less than 10 parts per million).
The interim certification policy which expires on
Dec. 31, 1987, contains additional options of tagging
40 percent of the grape bunches or placarding grapes
treated with sulfites. Under the extension issued today,
no such additional options are provided to certification
although they are still under consideration.
"We are not ruling out possible alternatives to
certification such as 100 percent tagging, but additional
time is needed to resolve this issue," said Doug Campt,
EPA's Director of the Office of Pesticides. "Right
now, we are still evaluating hundreds of comments
received on the revised interim policy. However,
because it will expire on Dec. 31, we need to proceed
with the certification program to enable the industry
to continue marketing grapes without disruption. This
action should effectively protect the sulfite-sensitive
population."
EPA is planning to hold meetings in early 1988
with other federal and state agencies, growers and
other interested parties to discuss alternatives to
certification, the content and operation of the certi-
fication programs during 1988 as well as the generation
of data underway for establishing a tolerance (allowable
residue level) of sulfites on grapes.

Sulfiting a^nts have been used for 40 years as fumigants on domestic
and imported grajMBS to prevent grey-mold or bunch-rot spoilage during
shipping or storage. These pesticides are applied in the form of gas or
pads (the pads are placed inside the shipping crates) impregnated with
sodium metahisulfite. Sulfites pose no health risk to most consumers, but
do pose a potential health risk to a relatively small number of sulfite-
sensitive individuals, the vast majority of whom are asthmatics.
In December 1986, the agency issued a one-year certification program
for marketing sulfite-treated grapes so that data could be obtained for
setting sulfur-dioxide tolerance levels. The certification policy allows
shippers and growers, foreign and domestic, to market grapes treated with
sulfiting pesticides provided they have a valid analysis certifying that
the grapes contain no detectable residues of sulfur dioxide (less than 10
parts per million).
A tolerance for sulfur dioxide on grapes was not required by EPA until
July 1986 because sulfites were "generally recognized as safe" (GRAS) by the
Food and Drug Administration (FDA). At that time FDA revoked the GRAS status
of the use of sulfites on fruits and vegetables to be served or sold raw to
consumers because sulf i te-sens it ive persons displayed adverse reactions to
sulfites. Although this action did not affect the use of sulfites on grapes,
EPA no longer considered the pesticide use to be GRAS.
Earlier this year, the California table-grape industry developed
information which indicates that repeated sulfite treatment during long-
term storage of grapes, necessary to maintain an even distribution of
grapes throughout the fall and winter months, may result in detectable
sulfur-dioxide residues (10 parts per million or higher). As a result,
the California table-grape industry petitioned EPA to consider amending
the interim certification policy and to allow placards or tags to be
displayed at points of sale for all sulfitetreated grapes. In August, EPA
granted the petition and required either placarding or tagging of 40 percent
of the grape hunches to notify consumers that the grapes had been treated
with sulfite.
The 1988 interim certification policy will permit shipment of tagged
grapes picked and packed prior to Dec. 31, 1987.

EPA TO CONSIDER	The U. S. Environmental Protection Agency has
OPTIONS FOR
REGULATING OIL	concluded that full-scale federal regulation of
AND GAS WASTES
wastes from the drillina and production of oil and
gas as hazardous wastes is not necessary at this time.
In a Report to Congress released today, EPA said
that present state and federal regulation of oil and
gas wastes appears to be generally adequate. The agency
also will consider working with states to review and
improve the design, implementation and enforcement of
existing state and federal programs to manage oil and
gas. The agency must recommend regulatory approaches
by June 1988.
Under the Resource Conservation and Recovery Act
(RCRA), the federal hazardous-waste-management law,
Congress must approve any regulatory action taken by the
agency on oil and gas wastes. Congress specifically
exempted oil and gas wastes from RCRA regulation,
pending completion of today's study and the regulatory
determination. However, the underground injection
of oil and gas wastes and waste discharges into
surface waters are currently regulated under the
federal Clean Water Act.
Dr. J. Winston Porter, EPA's Assistant Admini-
strator for Solid Waste and Emergency Response, said,
"We found that these wastes generally appear to be
adequately regulated at this time. Damage incidents
we documented from these wastes often occurred in
violation of current regulations, underscoring the
need for adequate enforcement of such requirements.
EPA will work closely with Congress over the next few
months to explore options for improving federal and
state controls and their enforcement, where necessary."

RECALLED FOR
EMISSION PROBLEM	that about half of the Alliances built by the American
Motors Corp. (AMC) in the 1983 model year are being
recalled to correct a hydrocarbon and carbon-monoxide
emissions problem. About 64,500 Alliances will have
an air-bleed assembly installed in a vacuum hose to
improve the air/fuel ratio. The repair also includes
a modification to an engine temperature sensor.
Automotive hydrocarbon emissions come from
unburned fuel that is releasd into the atmosphere.
Together with nitrogen oxides in the presence of
sunlight, these hydrocarbons can cause the formation
of ozone, a known respiratory irritant. Carbon monoxide
can reduce the body's capability to carry oxygen in the
blood.
The emission problems were discovered during EPA's
test program of in-use vehicles. AMC subsequently
agreed to recall the vehicles.
Dealers that sold Alliance cars are now known as
Jeep/Eagle dealers. Owners may take their vehicles to
any Jeep/Eagle dealer for free repair. Jeep/Eagle,
now a division of Chrysler Corp., began notifying owners
of the recall today.

EPA RESTRICTS
USE OF ALACHLOR
PESTICIDE AND
CONCLUDES SPECIAL
REVIEW
".'ne U.S. Environmental Protection Agency has placed
a number of restrictions on the use of the pesticide
alachi.or, including a requirement that use be limited to
certified applicators and that other label modifications
be included on alachlor products.
Today's action concludes a special review of
alachlor which EPA initiated in January 1985, based
on data which showed that exposure to alachlor resulted
in oncogenic effects (tumor causing) in mice and rats.
AI achlor is classified by EPA as a probable human
carcinogen. The occurrence of alachlor in ground water
ard surface-water supplies in areas of heavy use also
has been identified as a cause for concern.
Alachlor has been registered since 1969 as a
selective herbicide to control pre-emergent grasses and
broadleaf weeds. Annual use of alachlor is over 80
million pounds, making it one of the highest volume-of-
use herbicides in the United States.
Exposure to alachlor can occur through mixing,
loading and applying it to agricultural crops, eating
foods containing residues of it and drinking water
contaminated with residues.
As a result of all data evaluated since the special
review was begun, the agency has determined that
alachlor exposure to applicators can pose significant
risks, and the current actions are designed primarily to
reduce those risks. Dietary risk from alachlor,
assuming the actual percent of crops treated, is reason-
able given the benefits of continued use. The upper
bound risk of cancer from dietary exposure over a
lifetime is now calculated at about one person in one
million exposed.

Studies o£ over 50 mid-western community water supplies (surface water)
indicate that the levels which may occur in some cases are likely to be low
and usually seasonal in occurrence. The risks associated with alachlor
levels found in these surface-water supplies are generally in the one-in-
one-million range of cancer risk.
EPA will soon propose a Maximum Contaminant Level for alachlor in
public drinking water under the Safe Drinking Water Act. This would limit
alachlor contamination in public drinking water to a specific level which
does not pose unreasonable risks.
EPA found that available data were not adequate to make a definitive
evaluation of the risks of ground-water contamination which alachlor may
pose in areas of heavy use. To the extent that data are available from
well-water sampling, a small percentage of wells in areas of heavy use
contained alachlor, mostly in low concentrations (0.2 to 2.0 parts per
billion). Higher concentrations in well water appear to result from spills
and similar causes other than normal agricultural use. However, given the
widespread use of alachlor, the available data are too limited to be repre-
sentative. Thus, a determination on risk to ground water has been deferred
pending completion of an EPA required nationwide monitoring study by the
registrant due in 1989.
To reduce applicator, mixer/loader risks to reasonable levels, the
agency is requiring the following label modifications: restrict the use
of alachlor to certified applicators or persons under their direct supervi-
sion; require a mechanical transfer (pumping) system to mix and load alachlor
for all applicators who treat 300 acres or more annually with alachlor; and
reinstate aerial application with the provision that human flaggers are
prohibited. In addition, the following statements must appear on alachlor
product labels: "Restricted use due to oncogenicity"; "The use of this
product may be hazardous to your health"; and "This product contains alachlor
which has been determined to cause tumors in laboratory animals."
The benefits of alachlor were assessed in terms of economic effects
which would result if alachlor were cancelled and growers forced to use the
available alternatives. Cancellation of all uses of alachlor would result
in first-year losses at the farm level of $413 to $465 million, which
represents both increased costs for weed control and decreased value of
production. In addition, alachlor plays a significant role in conservation
tillage to prevent soil erosion. The overall benefits loss to society
would range from about S302 to $404 million the first year.
Alachlor is manufactured by Monsanto Chemical Co. under the trade name
Lasso®. Approximately 94 percent of the annual 80-84 million pounds of
this compound is used on three crops: corn (63 percent), soybeans (28 percent)
and peanuts (three percent). Other uses are on sweet corn, popcorn, cotton,
dry beans, grain sorghum, green peas, lima beans (green) and sunflowers.

EPA GIVES COMGRESS	Water quality in the United States has improved
STATUS OF NATION'S
WATER QUALITY	significantly in the past 15 years, despite population
and industrial growth, but persistent problems remain,
the U.S. Environmental Protection Agency told Congress
today. Basing its conclusions on information provided
by states, EPA says that toxic pollutants, ground-
water contamination, nonpoint source pollution and
wetland losses are among the important remaining problem;
affecting the nation's waters.
"The nation's commitment to improve water guality
has had significant results," said EPA Administrator
Lee M. Thomas. "About three guarters of the waters
we have assessed are clean enough for fishing and
swimming', and we have made substantial strides toward
improving pollution-control efforts at all levels of
government.
"Under the 1987 Clean Water Act amendments, new EPA
and state responsibilities are evolving in areas such
as toxics control and polluted runoff from diffuse
areas such as farms, construction sites and city streets
A basic challenge of the coming years will be to manage
these new responsibilities and maintain our aggressive
approach to controlling traditional pollutants from
factories and municipal sewage-treatment plants."
The report, titled "National Water Quality
Inventory, 1986 Report to Congress," is the sixth in a
series of biennial National Water Quality Inventories
published since 1975. It is based on water-quality
R-170

information provided to EPA in 1986 by states and other jurisdictions.
Water-quality conditions in about one-fifth of U.S. stream miles, one-third
of lake acres and one-half of estuarine waters are assessed in the report.
Estuaries are areas where fresh water meets salt water, such as bays and
mouths of rivers. The report says that 74 percent of assessed river miles,
73 percent of assessed lake acres and 75 percent of assessed estuarine and
coastal waters are clean enough to support the uses states have set for
them. Under the federal 1972 Clean Water Act, states were required to
designate bodies of water within their jurisdictions for different uses,
such as fishinq, swimming and drinking, and to set criteria or limits on
pollutants to guarantee these uses.
Of the roughly 25 percent of waters assessed in this report that do
not meet state use designations, nonpoint sources of pollution are cited
as the cause of water-quality degradation in 76 percent of lake acres, 65
percent of stream miles and 45 percent of estuarine waters . A nonpoint
source is one that cannot be traced to a specific spot. Examples include
agricultural fertilizer runoff or sediment from construction sites. By
contrast, of the roughly 25 percent of waters assessed in this report that
do not meet state use designations, point sources of pollution such as
sewage-treatment facilities and factories (which discharge wastes to waterways
through a pipe, conduit or other discrete point) are said to be the cause
of degradation in nine percent of assessed lake acres, 27 percent of assessed
stream miles and 34 percent of assessed estuarine waters. The remaining
waters *rith impairments are affected by natural conditions like low flow,
by miscellaneous sources like sediment contamination and acid rain or by
undetermined sources.
"Nonpoint sources appear to be increasingly important contributors
to use impairment," the report concludes. "Intensified data collection
efforts are certainly a factor in explaining their dominance. Another
explanation may be that nonpoint source impacts are becoming more evident
as point sources come under better control."
The report notes that progress in reducing the effect of point sources
has been well documented. Many rivers once seriously degraded by municipal
and industrial dischargers have been returned to health by the construction
of new treatment facilities. Loadings of key pollutants to waterways have
declined as levels of wastewater treatment have improved. Although nonpoint
sources are inherently more difficult to control, continued activity is
occurring in the application of nonpoint-source-management practices. The
report notes that EPA and the states will be expanding and improving their
water-pol lution-control programs under the impetus provided by Section 3 19
of the Clean Water Act amendments of 1987. In particular, new emphasis is
given to identifying waters impaired by nonpoint sources and toxic substances
and to implementing programs for their control.
Nevertheless, a variety of pollutants continues to be found in the
nation's waters at levels that prevent attainment of designated uses. The
most commonly reported pollutants include fecal coliform bacteria, excess
nutrients, turbidity, oxygen-demanding substances and toxic pollutants.
Nutrients contribute to eutrophication, a process in which a lake is choked
by abundant plant life. The toxic pollutants most often reported are
metals like mercury, copper and cadmium; polychorinated biphenyls (PCBs);
and pesticides like chlordane, DDT and dieldrin.
R-170

According to the report, 22 states found that 8,500 stream miles are
affected by toxic substances. Sixteen states found elevated levels of
toxics (above health or environmental protection standards) in 362,000
lake acres, and six states reported that 190 square miles of estuaries are
affected by toxics. Industrial discharges and agricultural runoff are
reported as the leading sources of elevated levels of toxics in the nation's
surface waters.
Contamination of fish tissue is also reported. Twenty-seven states
report finding detectable levels of toxics in some samples of fish tissue,
and 2 3 report concentrations in localised areas exceeding U.S. Food and
Drug Administration (FDA) action levels (levels above which FDA recoin'ien'ls
limiting consumption or not eating the substance at all). Tventy-four
states report 285 fishing advisories due to toxics. Fifteen states, nost
of which also reported having advisories, cite 108 fishing bans in selected
waters. Elevated levels of PCQs, mercury and chlordane are most often
cited as the reason for the bans and advisories.
These findings, EPA notes, may underestimate the number of advisories
and bans in U.S. waters, since not all states provided information on
fishing restrictions. Some bans and advisories may apply to different
segments of the same water body, or may apply differently to several species
of fish in the same water body.
Ground water, which provides drinking water for more than half of the
nation's population, is increasingly being recognized by the states as
vulnerable to contamination. The most freguently cited sources of ground-water
contamination are deficient septic systems, leaking underground storage
tanks and agricultural activities like fertilizer application. The states
report that sewage, nitrates (such as fertilizers) and synthetic organic
chemicals (such as petroleum hydrocarbons used in gasoline) are the three
most common contaminants affecting the nation's ground water.
EPA reports a significant increase in the past two years in the number
and variety of ground-water protection activities being conducted by the
states. Among these are the development of state strategies to protect
ground water .and expanded programs in ground-water classification, control
of pollutant sources and projection of wellhead areas (the land around
drinking-water wells).
Special concerns identified by the states, in addition to ground-water
protection and toxic substances, include nonpoint-source pollution, loss
o£ wetlands, funding needs, acid deposition and mine drainage into waterways.
The report discusses water-pollution-control programs being carried
out at the federal and state levels and includes information on a number
of new initiatives in estuarine protection, Great Lakes water quality,
water monitoring and sludge management. The report highlights and describes
the problems of a variety of U.S. waters, such as the Colorado River, the
Chesapeake Bay and Boston Harbor.

EPA PROPOSES	Calling urban ozone "the most widespread and
POLICY FOR AREAS
FAILING TO MEET	intractable air-pollution problem facing this country
AIR-POLLUTION
DEADLINES	today," U.S. Environmental Protection Agency Adminis-
trator Lee M. Thomas outlined a proposed new policy for
dealing with areas failing to meet the ozone and carbon-
monoxide pollution standards by the Dec. 31, 1987,
target date identified in the Clean Air Act. The policy
calls for sustained progress toward cleaner air without
severe social and economic disruptions—at least in the
near term.
EPA estimates that at least 50 areas, mostly larger
metropolitan areas, will fail to meet the standards for
either ozone or carbon monoxide, or both, by the end-
of-the-year date. The agency is waiting to compile
the 1987 air-quality data before making final deter-
minations.
"This policy is tough but reasonable," Thomas said.
"It will move cities steadily toward attainment of
the standards in two important ways. First, EPA will
continue to aggressively implement national air-
pollution-control measures such as the federal motor-
vehicle-control program, controls on gasoline
volatility and controls designed to reduce emissions
of gasoline vapors from cars and trucks. Second,
state and local governments in non-attainment areas
will implement additional measures designed to achieve
further reductions in ozone and carbon monoxide."
Thomas also noted that EPA's proposed strategy will
heiD C ?r e 53 in its deliber ".ions over r eaut n ? r : z a - : : ~

of the Clean Air Act. "This policy incorporates the kinds of measures that
can be implemented by federal, state and local governments," he said. "It
lays out flexible deadlines that we know cities and states can meet through
careful planning and determined implementation. It includes strong sanctions
against areas that fail to make adequate progress. And it proposes these
elements in a unified way for public scrutiny and comment. Congress will be
able to use this federal input as it works to extend and improve the federal
law."
EPA's proposed strategy prohibits construction of major new facilities if
attainment of the standards is not projected within three or five years o£
the agency's approval of required new state clean-air plans. The policy also
requires that most areas show reasonable progress toward attaining the
standards by committing to a minimum three-percent average annual reduction
in the pollutants, beyond federally-implemented measures and existing
requirements.
The requirement for continued annual improvement must be met after gaining
reductions to offset growth in the cities. Cities also cannot claim credit
toward the three-percent requirement for reductions achieved by such federal
measures as the motor-vehicle-control program or the eventual reductions due
to EPA's proposed plans requiring on-board canisters to reduce evaporative
emissions or changes in gasoline vapor pressure.
"Continued annual reductions in volatile organic compounds or carbon
monoxide will place great emphasis on the planning process, and rightly so,"
Thomas said. "The difficult decisions that must be made at the state and
local level will need the participation of all parties—the general public,
government officials, the health community, environmentalists, consumer
groups and various industry"representatives."
The agency intends to evaluate the 1987 air-quality data and issue calls
for new state clean-air plans (State Implementation Plans, or SIPs) early in
1988. The policy calls for certain commitments to near-term (1988-90) actions
and an inventory of all emission sources before submittal of the SIP for EPA
approval two years after the SIP call. EPA plans to issue its approval or
disapproval within one year of submittal.
"A thorough and accurate inventory of all sources, both large and small,
of volatile organic compounds is essential to the ultimate success of the
control plan," Thomas said.
EPA believes that in order to reach the standards, each non-attainment
area in the country will have to consider a range of stationary- and mobile-
source-control options. These may include the development of new technology,
the use of alternative fuels, innovative approaches to reducing vehicle
use, the development or improvement of mass-transit systems and the control
of numerous small pollution sources. The proposed policy establishes the
framework for areas to properly plan a long-term strategy to bring ozone
and/or carbon-monoxide levels down to the level of the standards which are
designed to protect public health.

The policy outlines the various sanctions available under the Clean Air
Act ranging from construction bans on major new sources to the withholding
of federal highway funds and clean-air and sewage-treatment grants. In the
near term, EPA is proposing that a construction ban on major new or modified
sources of volatile organic compounds (in the case of ozone) or carbon
monoxide be applied to areas not persuasively demonstrating attainment
within three years of EPA's approval of the plan. Areas may obtain a waiver
of two additional years if all reasonably available control methods do not
bring about attainment. The construction ban will also be applied to those
areas not meeting the commitments of currently approved plans. These bans
would be lifted only when an approved plan demonstrates attainment in the
near term (again, the following three or five years).
The agency proposes that highway funds (for certain areas), air grants,
and sewage-treatment grants be withheld if an area is not making reasonable
efforts toward implementing current or future plans. These sanctions will
be lifted only after the state makes such efforts or after a non-implemen-
tation finding is reversed. EPA is not proposing to apply sanctions to any
area for simply failing to attain tho standards.
In June, EPA announced a proposed disapproval of the clean-air plans
and a proposed construction ban for 14 areas of the country whose SIPs could
not persuasively demonstrate attainment of the standards by the end of the
year. In the case of one area, Cleveland, highway funding and clean-air-
grant sanctions were also proposed. Final determinations for these areas
are expected early next year. Today's proposed policy will likely apply to
those 14 areas.
Ozone is a photochemical oxidant and the major component of smog. While
ozone in the upper atmosphere is beneficial to life by shielding the earth
from harmful ultraviolet radiation given off by the sun, high concentrations
of ozone at ground level are a major health and environmental concern. Ozone
is not emitted directly into the air, but is formed through complex chemical
reactions between precursor "emissions of volatile organic compounds and
nitrogen oxides in the presence of sunlight. Both volatile organic compounds
and nitrogen oxides are emitted by transportation and industrial sources.
Volatile organic compounds are emitted from sources as diverse as autos,
chemical manufacturing, dry cleaners, paint shops and other sources using
solvents.
The health threat from ozone is particularly serious for those who suffer
from respiratory illnesses, but even healthy people can suffer adverse
effects. High levels of ozone can also substantially injure animals and
damage crops, forests and man-made materials.
The primary National Ambient Air Quality Standard for ozone is 0.12 parts
of ozone per million parts of air. It is a daily maximum one-hour average
that may only be exceeded three times in a three-year period.
Carbon monoxide is a colorless, odorless, poisonous gas produced by
the incomplete burning of fossil fuels. This pollutant tightly binds to
hemoglobin, the oxygen-carrying protein in blood, reducing the amount of
oxygen which reaches the heart, brain and other body tissues.- Exposure to
R-172

carbon monoxide particularly endangers people with coronary artery disease.
Even healthy people who are exposed to low levels of carbon monoxide can
experience headaches, fatigue and slow reflexes from lack of oxygen.
Motor vehicles account for almost two-thirds of the nationwide carbon-
monoxide emissions. The primary National Ambient Air Quality Standard for
carbon monoxide is an eight-hour average of nine parts per million not to be
exceeded more than once per year.
Today's proposed policy will appear in the Federal Register within the
next several days and will be open to public comment for 60 days.

EPA said 30,649 of the vehicles are California cars.
The affected models are the 1983 Chevrolet Impala,
Caprice Classic, Camaro, Malibu, Monte Carlo and
El Camino. Also included are the Pontiac Firebird,
Bonneville, Grand Prix and Parisienne and the GMC
Caballero. The models are equipped with 3.8, 5.0 and

598,588.
EPA said the problem is a defective thermal vacuum
switch (TVS) in the evaporative-emission control system
which fails to open and close properly causing the
vehicles to exceed the federal evaporative-emission
and carbon-monoxide limits.
GM began notifying owners of the recall today. An
improved TVS will be installed at no cost to the owners.
GM recalled nearly half a million 1982-model-year
vehicles in July which used the same TVS. The 1983-

UNITED STATES AND
CANADA SIGN AMEND-
MENTS TO GREAT
LAKES WATER
QUALITY AGREEMENT
Representatives of the United States and Canada
today signed amendments to the Great Lakes Water Quality
Agreement of 1972.
The amendments were signed by EPA Administrator
Lee M. Thomas and Canada's Minister of the Environment,
Tom McMillan, in Toledo, Ohio, at the biennial meeting
of the International Joint Commission.
"I am delighted that representatives from the
United States, Canada, the Great Lakes Basin states and
various public and private interest groups concerned
with the Great Lakes have made these crucial negotia-
tions such an unqualified success," said Thomas.
The original Great Lakes Water Quality Agreement,
also signed by the United States and Canada, addressed
the overall pollution and water deterioration in the
five lakes that resulted in excessive algae growth and
the contamination of fish. Amendments in 1978 broadened
the agreement, developing an integrated ecological
approach to researching and understanding the problems
of the lakes.
Thomas said that the latest amendments have been
designed to reflect the advancements in science and
technology since 1978. The amendments are also designed
to assure their prompt implementation.
The U.S. Department of State led the negotiations
of the amendments with Canada, while representatives
from the EPA's Great Lakes National Program Office
served as members of the negotiating team and provided
technical support.
The new amendments include the development of
individual lake management plans to control critical

pollutants; remedial action plans for severely polluted areas; programs to
address toxic substances entering the Great Lakes from air, land-runoff and
ground-water sources; and improved management and accountability procedures
to encourage better use of existing resources.
EPA Region 5 Administrator and National Program Manager for the Great
Lakes Valdas V. Adamkus said, "The amendments continue the giant strides the
United States and Canada have made in protecting and maintaining the Great
Lakes and their surrounding environment. In return, the lakes will continue
to enhance the quality of life, both economically and aesthetically, for the
entire region and beyond."

Christian Rice (202) 302—3324
EPA PROPOSES	New domestic regulations restricting production and
CUTBACKS IN
CFC PRODUCTION	consumption of the ozone-depleting chemicals called
TO PROTECT OZONE
LAYER	chlorofluorocarbons (CFCs) were proposed today by U.S.
Environmental Protection Agency Administrator Lee M.
i
Thomas.
"These rules will fully implement the Montreal
Protocol to protect the stratospheric-ozone layer,"
said Thomas. "Our proposal constitutes the American
response to the global commitment to reduce the risks
of stratospheric-ozone depletion."
The proposed rules require a freeze at 1986 produc-
tion and consumption levels of CFC-11, -12, -113, -114
and -115 on the basis of their relative ozone-depletion
weights. This freeze will be followed in mid-1993 by a
20-percent reduction from the 1986 levels and in mid-
1998 by a 50-percent reduction from the 1986 levels.
The rules would also prohibit production and con-
sumption of Halon 1211, 1301 and 2402 from exceeding
1986 levels on a weighted basis beginning in approxi-
mately 1992.
Imposed under Section 157 of the Clean Air Act, the
rules would constitute the United States' implementation
of the "Montreal Protocol on Substances That Deplete the
Ozone Layer" which was signed by 24 countries, including
the United States, on Sept. 16 in Montreal.
EPA proposes to allocate quotas reflecting the
allowable level of production and consumption to each
of the U.S. firms engaged in these activities in 1986.
Trading of allocated quotas would be permitted. Exports
and imports of the restricted chemicals will also be
allowed consistent with restrictions contained in the
Montreal Protocol. This approach will provide a
cost-effective means of achieving the regulatory goal,
R-177

spur technological innovation, minimize administrative requirements and
facilitate enforcement.
In a separate notice accompanying today's proposal, EPA is requiring
firms involved in producing, importing or exporting any of the regulated
chemicals in 1986 to report these activities to the agency.
"The spirit of cooperation exhibited by all parties concerned—the CFC
industry, the public interest groups, the scientific community and the
Congress—has enabled the United States to forge and maintain a position
of world leadership on the stratospheric-ozone issue," Thomas said.
The control requirements in today's proposal are scheduled to take effect
at the same time they are required under the Montreal Protocol. Article 16
of the Protocol provides that the Protocol will enter into force on Jan. 1,
1989, provided that 11 nations or regional economic integration organizations
representing two-thirds of 1986 global consumption have ratified the Protocol
by that date and that the Vienna Convention for the Protection of the Ozone
Layer has entered into force. Otherwise, the Protocol will enter into force
90 days after that condition has been satisfied.
The President of the United States is expected to transmit the Montreal
Protocol to the Senate for ratification as early as this month. U.S. ratifi-
cation is expected sometime in 1988.
Concern about possible depletion of the ozone layer from CFCs was first
raised in 1974 with publication of research which theorized that chlorine
released from CFCs could migrate to the stratosphere and reduce the amount of
ozone which shields the planet from harmful ultraviolet radiation. Because
some of the CFCs have an atmospheric lifetime of over 120 years and do not
break down in the lower atmosphere, they migrate slowly to the stratosphere
where higher energy radiation strikes them, releasing chlorine. Once freed,
the chlorine acts as a catalyst repeatedly combining with and breaking apart
ozone molecules. If ozone depletion occurs, because of the long atmospheric
lifetimes of CFCs, it will take from many decades to over a century for the
ozone layer to return to past concentrations.
In 1978, EPA and the Food and Drug Administration banned the use of CFCs
as aerosol propellents in all but essential applications. During the early
1970s, CFCs used as aerosol propellents constituted over 50 percent of total
CFC consumption in the United States. This particular use of CFCs now has
been reduced by approximately 95 percent of the amount consumed in aerosols
in 1974. Today's proposal does not affect the 1978 regulations. Since
1978, CFC use has continued to expand in other applications (e.g., as a
foam-blowing agent, refrigerant and solvent). Total production in the United
States now has surpassed pre-1974 levels. Since 1983, worldwide production
of CFCs has grown at an average annual rate of five percent.
EPA's regulatory impact analysis of today's proposed rules assessed the
costs and benefits over the period 1989-2075. Costs of reducing CFCs and
halons called for in the proposed rules are estimated at under SI billion
through the year 2000. For those areas where quantification was possible,
monetary benefits would far outstrip costs.

The proposal meets the requirements of an agreement settling a lawsuit
brought by the Natural Resources Defense Council in the District Court of
the District of Columbia seeking to compel EPA to promulgate regulations
under Section 157 of the Clean Air Act.
Today's proposed rules, which will appear in the Federal Register within
the next several days, have a 60-day public comment period. A public hearing
is planned and will be announced in the near future.
