Vol. 2, No. 2	APRIL 1981
This bi-monthly news bulletin is intended to inform all persons concerned with theToxic
Subtsances Control Act (TSCA) about recent developments and near-term plans. For
further information or to request copies of documents mentioned, write the Industry
Assistance Office (IAO), (TS-799) OPTS, U.S.E.P.A., Washington, D.C., 20460 or call

REGULATORY & REQUIRED ACTIONS
PREMANUFACTURE NOTIFICATION (PMN)...
SECTION 5
Under Section 5(a)(1) a person who intends to introduce
into commerce a chemical substance not on the TSCA
Inventory must notify EPA at least 90 days before begin-
ning manufacture. This rule applies also to imports. The
notice must give the chemical identity, production
volume, uses, byproducts, occupational exposure and
any health and environmental effects information in the
submitter's possession. EPA reviews this notification to
determine if the substance might present an unreason-
able risk that should be remedied through either an
order to develop sufficient information or an imme-
diately effective rule. Upon such a determination, EPA
issues an order to prohibit manufacture and then ap-
plies to the court for an injunction to this effect. This
order must be issued 45 days before the notification per-
iod ends. The original period may be extended by EPA for
up to 90 days for good cause. Absent such an order or
immediate rule, the manufacturer may proceed with his
plans. EPA publishes in the Federal Register a summary
of each PMN shortly after receipt and a report on all
current receipts each month. Copies of the revised pro-
posed forms for manufacturers, importers and exporters
are available from IAO for use by submitters during the
interim period (See 44 FR 28564, May 15, 1979 and 44
FR 59764, Oct. 16, 1979).

INTERAGENCY TESTING COMMITTEE (ITC).
4(e)
SECTION
Under Section 4(e), the ITC was established to recom-
mend to EPA substances which should be tested for
specified effects to determine their hazardous potential
to human health or the environment. Committee
members are: Council on Environmental Quality (CEQ),
Department of Commerce (DOC), Environmental Protec-
tion Agency (EPA), National Cancer Institute (NCI),
National Institute of Environmental Health Sciences
(NIEHS). National Institute for Occupational Safety &
Health (NIOSH), National Science Foundation (NSF) and
the Occupational Safety & Health Administration
(OSHA). The ITC may list up to 50 chemicals or catego-
ries of chemicals for testing and is to consider revising or
adding to its list every six months. The EPA Administra-
tor must respond within one year to each recommenda-
tion by initiating rulemaking under Section 4 or giving
the Agency's reasons for not doing so. Both the ITC
reports and EPA responses appear in the Federal
Register.
Date
No. of Single
Chemicals or
Categories
On January 9, 1 981, a federal district judge placed EPA
on a court-ordered schedule for making decisions con-
cerning all the chemicals designated for testing in the
first five ITC priority lists. EPA had been sued by the
Natural Resources Defense Council for its failure to
initiate rulemaking, or to offer an adequate explanation
why testing should not be required, within the one-year
time limit established in Section 4(e) of TSCA
In the ruling, Judge Lawrence W. Pierce, of the South-
ern District of New York, ordered EPA to proposed rules
or decisions not to test by the end of 1983 for ail chemi-
cals listed in the first five ITC reports. This schedule had
been submitted to theCourton September 12, 1980and
was accepted without charge. On February 13, 1981,
EPA filed its first required progress report with the
Court. It stated that EPA expects to comply with the
1981 schedule.

DENIAL OF CFC EXEMPTION SECTION 6
Under Section 6, EPA is authorized to control a chemical
as a hazardous substance if the Agency finds that the
chemical will present an unreasonable risk of injury to
human health or the environment.
EPA has recently denied a second request (46 FR 6062)
to use CFCs in aerosol sprays generating smoke and fog
for theatrical productions. On March 17, 1978, (43 FR
11318) EPA published a rule prohibiting almost all
manufacturing, processing and distribution in com-
merce of CFCs for aerosol propellant uses that are sub-
ject to TSCA. The intent of the rule, which became
effective on Octoboer 15, 1978, was to reduce CFC
emissions to the atmosphere in an attempt to reduce the
health and environmental risk caused by depletion of
the ozone layer. However, certain exmpetions based on
essential use were written into the rule Prior to issuing ,
the rule, EPA had considered and denied a request to
grant an exemption for inclusion of CFCs in the stage
product. EPA determined the use was not essential and
a CFC substitute could be found. In the recent petition
the distributor of "Fog Juice," which is a mixture of CFC
propellant and mineral oil, said no workable substitute
for CFCs could be found to produce the desired theatrical
effect. In the recent denial EPA said alternative pro-
ducts, if not perfect substitutes, do exist. Even without
substitutes, the Agency said exemptions would be
granted only if the health, environmental and economic
impacts of the removal were unacceptable.

REPORTING RULES
PRELIMINARY ASSESSMENT INFORMATION
SECTION 8(a)
Under Section 8(a), EPA may require manufacturers and
processors to submit various kinds of information
already in their possession on particular chemical sub-
stances or mixtures.
OnJanuary26, 1981 (46FR3199), EPA proposed a rule
that would require the reporting of quantities of asbes-
tos used in various processes, employee exposure and
monitoring data, waste disposal and pollution control
information, EPA had previously published, on October
17, 1979, an advanced notice of proposed rulemaking
(44 FR 60055) as part of a joint coordination of regula-
tory activities with the Consumer Product Safety Com-
mission. If the proposed rule later becomes a rule, EPA
collected information will be used to aid the Agency in
deciding the appropriate regulation action under TSCA.
For the purposes of this rule and to be consistent with
the definitions of TSCA, a manufacturer of asbestos is
any person who mines, mills or imports asbestos in bulk
or imports a product containing asbestos. A processor of
asbestos is any person who makes productsfordistribu-
tion in commerce that contain asbestos or any asbestos
containing component. To reduce the impact on small
businesses, EPA proposed to not require reporting from
companies of 10 or fewer employees. Additionally, the
proposal would require full reporting from only a repre-
sentative sample of the industry in most cases.
NOTIFICATION OF EXPORT... SECTION 12(b)
Under 12(b) exporters are required to submit a notice for
the first annual shipment of a substance to any given
country for any chemical substance or mixture subject
to final Section 4 testing rules; Section 5(b)(4) risk listing
for test data; proposed or final Section 5 and 6 rules;
orders issued under Section 5 or any action pending or
relief granted under Sections 5 or 7.
There is no notice form required, but the notice, sub-
mitted by mail to EPA, must include the exporter's name
and address, the name of the substance or mixture, the
date of export or intended export, the country of import
and the section of TSCA under which EPA has taken
action. Within five working days, EPA will advise the
foreign government of the impending exportation and
the U.S. regulatory action taken with respect to the sub-
stance or mixture.
The Section 12(b) rule as of March 1, 1981 applies to
the following chemicals by reason of the stated TSCA
actions:
F = final rule
P = proposed rule

ACTIVITY
CHEMICAL ACTIVITIES STATUS REPORT
The second edition of EPA's Chemical Activities Status
Report is now available. The two-volume report, current
to July 1 980, is a compilation of EPA's chemical related
activities relating to laws administered by the Agency,
including the Clean Air, Clean Water Acts, the Federal
Insecticide, Fungicide and Rodenticide Act; the
Resource Conservation and Recovery Act; the Safe
Drinking Water Act and TSCA. The chemical activities of
EPA's Office of Research and Development are
included Chemical substances are listed alphabetically
and by Chemical Abstract Service Number. There is also
a chemical name synonym list. This report includes
chemical regulatory activities, ongoing and completed
technical assistance information, preregulatory assess-
ments, chemical and biological testing and monitoring
programs and labeling requirements. Using the status
report, a researcher can quickly learn who in EPA regu-
lates a chemical and what scientific or technical work
has been done on the substance.
TSCA STATUS REPORT FOR EXISTING CHEMICALS
The latest TSCA status report booklet, Volume 2 Issue
1, listing all existing chemicals of interest to the TSCA
program, is now available. In this document the regula-
tory assessment status of each chemical is arranged
alphabetically by CAS number and there is an index of
regulatory assessment status within each TSCA pro-
gram. This booklet differs from the Chemical Activities
Status Report mentioned elsewhere in this Bulletin,
being limited to only TSCA activities, while the Chemical
Activities Status Report covers all programs of EPA.
Because of its more limited nature, the TSCA status
report is more up to date. It also uses different data
bases.
FIRST REPORT OF THE ITSDC
The first report of the Interagency Toxic Substances
Data Committee (ITSDC) will be published shortly and
IA0 is accepting reservations for the booklet. Under
Sections 10 and 25 of TSCA the committee is responsible
for Federal chemical information system development
and coordination. The ITSDC's goal is to systematize the
retrieval of toxicological and other scientific data to aid
those people responsible for research, risk analysis and
decisionmaking. This first report summarizes the pro-
gress to date.
EPA APPROVES PCB DISPOSAL UNITS
The use of two high-temperature commercial incinera-
tors capable of destroying concentrations of PCBs has
been approved by EPA. The facilities, the first chemical
waste incinerators ever to receive EPA approval, are
located in Texas and Arkansas and may be a major step
in dealing with one of the most important environmental
problems in the United States.
Enacted in 1 976, TSCA required EPA to prohibit manu-
facture, processing, distribution and use of PCBs and to
establish PCB storage and disposal rules. Since then,
EPA has ruled that wastes containing over 500 parts per
million of PCBs can only be destroyed in high tempera-
ture (above 1200°C) incinerators operated under con-
trolled conditions. Up to now no incinerators have met
6

-------
these EPA burn standards. EPA has estimated there are
more than 20 million pounds of PCB liquids in storage
awaiting destruction.
In announcing EPA's approval of the commercial incin-
erator in Deer Park, Texas and owned by Rollins Envi-
ronmental Services, Adlene Harrison, EPA's Region 6
Administrator said on January 23, "After exhaustive
testing and careful analysis, I am confident that the
facility at Rollins has demonstrated the ability to destroy
PCBs safely. The continued storage of millions of
pounds of these dangerous chemicals pose an eminent
threat to the American people and ourenvironment. It is
vital that we remove this material from our midst and
destroy it promptly. I am pleased that we can begin to do
so, providing safe destruction of PCBs already now
being stored and the nearly 750 million pounds still in
service which will have to be disposed of in the future."
On January 28, Harrison approved a second incinerator
at El Dorado, Arkansas, owned by Energy Systems Com-
pany. The El Dorado facility is capable of burning liquids
and solids. The Deer Park incinerator burns only liquids.
Tests on both incinerators in 1979 determined that they
destroy more than 99.9999 percent of the PCBs in high-
level waste oil. Additional tests were conducted to 1980
to insure that the local environment and public health
was not threatened by use of the incinerators.
PCBs, in use since 1929, do not decompose easily. Their
characteristics of low flammability and low conductivity
of electricity have made them popular during the past 50
years for use in fluids and lubricating oils especially in
transformers and capacitors. PCBs also were used in
varnish, wax, glue, carbonless copy paper, sealants,
printing ink and in many other products. Highly stable,
PCBs break down slowly and therefore not only persist
in the environment years after being discarded but also
accumulate in the fatty tissues of humans and animals.
In laboratory animals, PCBs have been shown to cause
cancer, reproductive failures, gastric disorders and skin
lesions. PCBs are suspected of causing cancer in
humans.
In the 1980 tests at the two incinerators, EPA closely
monitored for the presence of toxic byproducts.
Tetrachlorodibenzo-p-dioxins and tetrachlorodibenzo-
p-furans were detected at extreme low levels, in the
range of billionths of parts per gram the Agency said.
These tests were conducted so that EPA could estimate
the health risk to determine if there was any potential for
adverse impact. The intent of the estimate was to find
the highest conceivable risk. "It is highly improbable
that a significant health risk exists," Harrison said, of
the test at the Rollins facility. The worst possible situa-
tion she said, "is if someone lived near the Rollins facil-
ity and was exposed to the maximum ground level
concentration of emissions from PCB incinerators con-
tinually for 70 years." Even so, she said, "The chances
of any increased cancer would be less than one in
50,000."
IAO SLIDE SHOWS
The IAO has recently updated and made available, free
of charge, four TSCA slide shows. These shows espe-
cially directed toward chemical manufacturers, proces-
sors and importers, go into detailed explanations of
TSCA, TSCA testing, PMN, and 8(e) requirements.
1. TSCA—An Overview of Its Authorities and Major
Activities—Recently updated, the 25-minute presen-
tation covers major actions to date, reviews impor-
tant aspects of the law and how the Act is being
implemented.
2.	Testing Under TSCA—Highlights how chemicals are
selected for TSCA priority testing, how model stand-
ards for testing rules are developed, who benefits
from testing and current action under Section 4.
3.	Section 8(e)—Substantial Risk Notification—A 12-
minute explanation of the notification process, de-
scribing two types of reports, how a company
reporting system could be organized, who is respon-
sible for reporting, how to determine which health
and environmental effects would be considered sub-
stantial risk.
4.	Proposed Premanufacture Notification Regulations
and Interim Policy Guidelines—A comprehensive 28-
minute review of the PMN program, what determines
a new chemical substance, use of the Inventory, who
must submit PMN forms, how to fill out forms and
current action and information.
Call the toll free number to reserve one or all of the slide
shows. TSCA regional coordinators also have copies of
the four shows ready for loan. The regional coordinators
are listed elsewhere in this issue of the Bulletin.
CHEMICAL INFORMATON RESOURCES HANDBOOK
The IAO now has available a new handbook that gives
detailed information on more than 85, mostly auto-
mated, chemical information systems and how each
data base can be reached. The Chemical Information
Resources Handbook explains each system's scope, and
how access is gained. If available, a sample of each
system's search/output is included in the directory plus
the latest known cost of using each service. The hand-
book can aid in searches on chemical toxicology, envi-
ronmental effects, spill resources, disposal methods,
ambient air and water concentrations, control technolo-
gies and governmental regulations.
The IAO has available two March 10, 1981 Federal
Register notices on PCBs. Both notices are responses to
a recent U.S. Court of Appeals ruling that set aside parts
of EPA's PCB rule on classifying of transformers,
capacitors and electromagnets as totally enclosed. One
of the notices spells out the inspection and maintenance
procedures that will be in effect for an 18-month period.
The second notice is an advance notice of proposed
rulemaking. It discusses the court ruling, EPA's need for
more factual information about electrical equipment
and asks for comments about the propensity of electrical
equipment containing PCBs to leak, the nature of expos-
ure to PCBs and the cost of reducing or eliminating PCBs
in electrical equipment. EPA set December 7, 1981 as
the deadline for comments. Call the toll free number for
copies of both March 10, 1981 Federal Register notices.
REGIONAL TOXIC SUBSTANCES COORDINATORS
Each week, the IAO responds to between 500 and 1,000
telephone calls requesting clarification of TSCA's provi-
sions or literature published under the program. In addi-
tion, hundreds of letters are received each week.
Information about TSCA may also be obtained from the
10 regional offices EPA maintains under the program.
Listed below are the names of the regional TSCA Coordi-
nators, where their offices are located and the States
and areas they serve. They, too, will assist you.
