REGULATORY & REQUIRED ACTIONS
TESTING OF CHEMICAL SUBSTANCES
AND MIXTURES ... SECTION 4
Section 4 of TSCA gives EPA authority to require manu-
facturers or processors of chemicals to test the toxic ef-
fects of a designated substance. To require testing EPA
must find that the chemical may present an unreasona-
ble risk; that there are insufficient data available with
which to perform a reasoned risk assessment; and that
testing is necessary to generate such data. A test rule
may also be based on an EPA finding of substantial pro-
duction and exposure to humans or the environment, in
addition to findings of insufficient data and need for
testing.
Under section 4(e) an Interagency Testing Committee
(ITC) was established to recommend chemicals to EPA
for priority consideration. The ITC can designate up to
50 chemicals or categories of chemicals for testing and
EPA must respond within one year by starting rulemak-
ing under section 4 or giving reasons for not doing so.
Section 4(f) TSCA requires EPA within 180 days after re-
ceipt of test data or other information that indicates a
chemical substance or mixture may pose a significant
risk of serious or widespread harm to human beings
from cancer, gene mutations or birth defects to: a) initi-
ate appropriate action under sections 5, 6, or 7 of TSCA
or b) publish a notice saying why the risk is not unrea-
sonable. The 180-day review may be extended for up to
90 additional days for good cause.
Section 4 Rule Proposed for MO
On July 5, 1983 EPA proposed a section 4 rule to require
manufacturers and processors of mesityl oxide (MO) to
test the chemical for various health effects (48 FR
30699).
The tests proposed to be required involve chronic toxic-
ity (with an emphasis on blood disorders) and mutage-
nicity. If positive results are obtained in the mutagenic-
ity tests, then EPA proposes that MO also be tested for
oncogenicity. In the July 5, 1983 notice, EPA responded
to the June 1, 1979 ITC designation of MO for priority
testing consideration including carcinogenicity, muta-
genicity, teratogenicity, other chronic health effects and
epidemiology studies.
The proposed rule does not include an epidemiology
study because EPA believes that no end point has been
sufficiently well-defined to make an epidemiology study
worthwhile at this time. EPA also did not propose that
MO be tested for teratogenicity because there is no evi-
dence to suggest the chemical produces teratogenic
effects.
Persons wishing to submit oral or written comments on
this proposed rule should call or write the TAO for full
details. EPA will hold a public meeting on the proposed
rule on September 19, 1983, in Washington, D.C., if
there is public interest in doing so.
4,4'-Methylenedianiline Under Accelerated Review
On July 11, 1983 (48 FR 31806) EPA said it is not initiat-
ing rulemaking at this time under section 4(a) to require
health effects testing of 4,4'-methy!enedianiline be-
cause it received data from a recent study that show the
chemical to be a carcinogen in both rats and mice. The
data EPA received are from a recently completed Na-
tional Toxicology Program (NTP) 2-year carcinogenicity
study. Based on the NTP data, EPA, under section 4(f)
1

-------
authority, initiated on April 27, 1S83 (48 FR 19078) a
180-day review of the chemical and said in the July 11,
1983 notice it doss not believe data obtained from
testing for other health effects are likely to change the
regulatory decisions lhat will be based on the NTP
information.
On June 1, 1979 (44 FR 31866) 4,4'-methylenedianitine
had been designated by the ITC for priority considera-
tion under section 4(e). The July 11, 1983 notice was
EPA's response to the ITC recommendation,
EPA Propose* Cresols Health Effacts Testing
EPA has proposed to require manufacturers and
processors of cresols to test these chemicals for certain
health effects. If the rule becomes final, the cresols
tests would be for carcinogenicity, mutagenicity, terato-
genicity, reproductive effects, neurotoxicity, skin sensi-
tization and subchronic toxicity. The proposed rule is
EPA's response to the ITC designation of cresols as pri-
ority candidates for testing for certain haafth effects.
In its designation of cresols, the ITC included testing for
environmental effects, specifically chronic effects in
fish and aquatic organisms [October 12, 1977 (42 FR
55026)1. EPA in its notice [July 11, 1983 (48 FR 21812)1
did not propose any additional environmental effects
testing, EPA said information is available for it to rea-
sonably predict that exposure of aquatic organisms to
cresols should not cause chronic effects. However, the
EPA decision not to tast for environmental effects is a
preliminary decision and the Agency is specifically re-
questing comments on that decision. If comments are
such that EPA decides thai environmental effects
testing is required, then chronic effects testing for
aquatic vertebrates and invertebrates (fresh water and
salt water) will be required in the final rule. Written
comments should be sent Dn or before September 8,
1983 to:
OPTS-42Q32 (DCNI
TSCA ITS-793)
E-108
Washington, D.C. 20460
EPA will hold a public meeting on the proposed rule on
September 28, 1983 in Washington, D.C. Persons
wishing to submit oral comments on the proposed rule
should call or write the TAO for full details.
4-CBTF Negotiated Test Program Stands
EPA has found [July 18, 1983 148 FR 32730)) no reason
to alter a 1982 decision not to initiate rulemaking under
section 4(a) to require environmental or health effects
testing of 4-chlorobenzotrifluoride (4-CBTF). The No-
vember 8, 1982 preliminary decision {47 FR 50S5S) was
made pending consideration of public comments on a
testing proposal submitted to EPA by Occidental Chem-
ical Corporation, the sole U.S. manufacturer of 4-CBTF.
EPA said the 1982 negotiated testing program, since
modified to respond to techncia) comments, would pro-
vide sufficient data to reasonably determine or predict
the health and environmental effects of 4-CBTF. The
chemical had been designated by the ITC in its 9th Re-
port, for health and environmental effects testing
consideration.
Data Reimbursement Rule Made Final
A final rule setting forth methods of determining fair
amounts for data reimbursement and for resolving dis-
putes arising over allocation of the costs of testing re-
quired by a section 4(a) test rule was published on July
11, 1983 (48 FR 31786). This rifle potentially affecls all
persons subject to a test rule under section 4(a). How-
ever, EPA believes that in most cases companies sub-
ject to a test rule will be able to work out voluntary cost
sharing arrangements. When parties cannot agree,
TSCA requires EPA 10 order fair and equitable reim-
bursment. The final rule provides for an independent
hearing officer to propose an order after an informal
hearing resembling commercial arbitration. The rule
also contains guidelines for the hearing officer's deci-
sion, suggesting that in most cases test costs and toe
fairly apportioned on the basis of market share. The
proposed order of the hearing officer may be appealed
to the Agency, and to a Federal district court.

REGULATION PENDING DEVELOPMENT OF
INFORMATION ... SECTION 5(e)
The Administrator may issue a section 5(e) order to
take effect at the end of the PMN review period. The or-
der may limit or prohibit manufacture, processing, dis-
tribution in commerce, use or disposal of the sub-
stance. The action can be taken if information available
to EPA is insufficient to permit a reasoned evaluation of
the risks, and if the substance may present an unrea-
sonable risk to either health or the environment. A 5(e)
order may also be issued if there is insufficient infor-
mation and the substance may be produced in large
quantities and may result in significant or substantial
human exposure, or substantial release to the envi-
ronment.
A 5(e) order can be a consent order or a unilatera •
der. In a consent order the company that submitte a
PMN negotiates the terms of the order with EPA, an
the company agrees that it is bound by the order an
waives its rights to file objections to the order,
waiver does not affect any other rights that the compa-
ny may have under TSCA.
In a unilateral order, EPA takes unilateral action in re-
stricting or prohibiting the manufacture, import, or use
in commerce of the PMN substance and EPA sets a date
for the proposed order to become an order.
EPA Issues 5(e) on Shale-Derived Syncrude
A 5(e) consent order has been issued for a PMN for a
full range, dewaxed, dearsenited shale oil (Syncrude).
The PMN subject to the order was submitted by the Un-
ion Oil Company of California. The consent order was
the first to be issued on the basis of substantial produc-
tion volume and substantial exposure and release. The
order mandates restrictions on production, volume,
worker exposure controls, and waste handling, pending
development of sufficient information. The order indi-
rectly controls the 105 expected shale-derived refining
streams that may be generated from Syncrude, which
were part of Union Oil's total PMN submission.
5(e) Order for Two Chlorinated Aio Pigment PMNs
EPA has determined in a recent proposed 5(e) unilateral
7

-------
order that the information made available to it in two
PMNs (82-678 and 82-679) is insufficient to permit a
reasoned evaluation of potential health effects.
EPA further determined thai the manufacture, importa-
tion, processing, and use of the two PMN substances
may present an unreasonable risk of injury to human
health by producing carcinogenic effects. The order will
take effect on August 28, 1983, unless the company,
which submitted both PMNs, files appropriate objec-
tions with EPA. The company claimed its identity, the
specific chemical identities and the estimated import
volumes to be confidential business information. EPA
used the generic term "chlorinated azo pigments" to
describe the susbtances in both PMNs. The company
said the PMN substances would be used as pigments in
paint formulations.
EPA said concern exists for both PMN substances due
to the potential for formation of metabolites that may
produce carcinogenic effects. If the substances undergo
azo reduction, each substance wauid produce a metab-
olite that is closely related to other substances already
found to be carcinogenic in test animals. Importation
will be banned pending development of data on the
PMN substances.
Issue 5(e) Orders for Two Dye Submissions
EPA has issued proposed 5(e) unilateral orders for two
separately submitted PMNs, because the information
available indicates that each PMN substance may be
carcinogenic. The PMNs, 83-401 and 83-418, are for
dyes for fibers and fabrics. Their generic names are
(83-401) naphthalenetrisulfonic acid, chlorotriaiinyl-
amino-methoxymethylphenylazo-, and (83-418)
benzendisulfotiic acid, chlorotriazinylamino-
dimethylphenylszo-sulfonaphthaleneazo. Each PMN
stated that the company intended to import the PMN
substance. In its order for each of the two PMNs, EPA
said it determined that the PMN substance may present
sn unreasonable risk to human health. Unless the sub-
mitter of 83-401 file objections, the proposed order will
take effect on September 4, 1983. The order for 83—416
becomes effective on September 14, 1983 unless the
submitter files objections.
Correction
On paQB 8 of the May 1983 Cftemicals-in-Proaress Bulle-
tin an incorrect date w#a flivan for the 6(e) consant order
for PMN 83-255. The correct date of the order is April 8,
1983.
REGULATION OF HAZARDOUS SUBSTANCES . SEC-
TION 6
Under section 6, EPA is author wad to control a chemi-
cal as a hazardous substance if the Agency finds that
the chemical will present an unreasonable risk of injury
to human health or the environment. Under 6ja), EPA is
required to apply one or several requirements of the
law to the extant necessary to protect against the risk.
EPA May Regulate MBOCA
EPA published an advanced notice of proposed rule-
making for 4,4'-methylene bis (2-chloroaniline). Also
known as MBOCA, it is used as a hardener or curing
agent in the manufacturing of certain polyurethane
plastics. MBOCA has been demonstrated to be carcino-
genic in animals, and EPA said that the risk from expo-
sure to MBOCA may be unreasonable [May 23, t983 <48
FR 22954)3, In the notice, EPA said it wilt explore a
range of regulatory options including a partial or com-
plete ban.
EPA has strong evidence that MBOCA is carcinogenic in
several species. MBOCA has produced malignant tu-
mors in the lung, liver, mammary gland and Zymbal's
gland in rats at statistically significant rates, In mice
and dogs MBOCA has produced malignant tumors and
the notice said "the carciriogencity of MBOCA in animal
studies demonstrates its potential for human car-
cinogencity."
MBOCA is used in the production of some coatabie
polyurethane elastomers and polyurethane surface
coatings. Most elastomers using MBOCA are industrial
products, such as belts, gaskets, gears, rollers and solid
tires. Other elastomers using MBOCA are consumer
products, including heels and soles for shoes, sport
boats and skate wheels.
In 1979 manufacture of MBOCA ended in the United
States. Current estimates of importation range from 1
to 3.5 million pounds a year. This supply is used in
some 200 to 400 polyurethane production plants, where
there are many opportunities for human exposure, es-
pecially in the workplace. Exposure to MBOCA occurs
primarily from dust during handling and from vapor
from heat curing.
Quarterly Progress Report to Court on PCB Rulemaking
EPA in the next few months will be able to reasonably
estimate safe levels of PCBa in uncontrolled PCB proc-
esses. These processes produce PCBs as byproducts in
products, or release PCBs to air, water, and wastes
above the limits of quantitation in these media. This
progress was recently described in an affidavit filed
with the U.S. Court of Appeals for the District of Colum-
bia Circuit. EPA, by filing the quarterly report, was com-
plying with a December 17, 1982 court order that stayed
a previous court mandate on uncontrolled PCB proc-
esses and orderd the Agency to file quarterly reports
describing the progress and status of its actions on
uncontrolled PCBs. EPA plans to propose the rule for
uncontrolled PCB processes in December 1983.
"The Agency's hazard assessment efforts on uncon-
trolled PCBs are focused on the review of data on carci-
nogenicity and reproductive/developmental effects of
PCBs," the EPA report said.
The purpose of the exposure assessment is to estimate
relative magnitudes of exposure to uncontrolled PCBs
under various scenarios, the court was told, "Because
of the number of chemicals potentially covered by this
(PCB) rule, snd the fact that the Agency lacks detailed
data on each chemical, an approach is being followed
that emphasizes hypothetical exposure scenarios based
on assumptions for frequency, duration, and other key
parameters needed for calculating exposure," the re-
port said. "As part of this effort, EPA has identified
chemicais that have a relatively high potential for gen-
erating PCBs as byproducts,"
S

-------
In addition to these internal EPA activities, on April 15,
1983, the Environmental Defense Fund, the National Re-
sources Defense Council, and the Chemical Manufac-
turers Association jointly submitted a proposal for a fi-
nal rule on the inadvertent generation of PCBs. The
proposal contains two parts: proposed regulatory lan-
guage and a document explaining why the proposed
regulatory language comports with section 6(e) and is
supportable by the available evidence.
EPA views this submission as a welcome contribution
to the uncontrolled rulemaking and has given it sub-
stantial review and consideration. EPA anticipates that
the basic framework fo the proposal will be incorpora-
ted into its proposed rule for uncontrolled PCBs.
Copies of the report to the court are available through
TAO.
REPORTING RULES
HEALTH AND SAFETY RULE ... SECTION 8(d)
Section 8(d) authorizes EPA to promulgate rules on
specifically listed chemicals and categories of chemi-
cals that would require manufacturers and processors
to submit lists and copies of health and safety studies
that they have conducted or were initiated by them.
EPA Adds 5 Chemicals to 8(d) List
An amendment to the 8(d) final rule has added five sub-
stances to the list for which lists and copies of unpub-
lished health and safety studies must be submitted to
EPA [June 1, 1983 (48 FR 24366)]. All five added sub-
stances had been designated for testing by the ITC in its
12th report (see the May 1983 Bulletin, p. 2). The sub-
stances and their Chemical Abstract Numbers are:
7-Nitro-2,2-dimethyl-2,3-
dihydrobenzofuran
13414-55-6
Calcium naphthenate
Cobalt naphthenate
Lead naphthenate
Methylolurea
2-Phenoxyethanol
61789-36-4
61789-51-3
61790-14-5
1000-82-4
122-99-6
EPA Proposes to Add Substances to 8(d) List
A proposal to add six substances and one mixture to
the section 8(d) list was made on June 22, 1983 (48 FR
28483). If this proposal becomes final, lists and unpub-
lished health and safety studies for these substances
voill have to be submitted to EPA. The chemical sub-
stances named in the proposed rule had been recom-
mended for testing by the ITC in its 11th report (see the
January 1983 Bulletin, p. 2). The one designated mix-
ture named is "aromatic C, fraction from petroleum
refining." EPA is adding this mixture because it has re-
sponded to the ITC's recommendations on mixed ethyl-
toluenes and trimethybenzenes by proposing that the
aromatic C, fraction containing these substances be
tested. The six substances, the designated mixture, and
their Chemical Abstract Numbers are:
Trimethybenzenes (mixed
isomers)	25551-13-7
1,2,3-Trimethylbenzene	526-73-8
1,3,5-Trimethylbenzene	108-67-8

7-Amino-2,2-dimethyl-2,3-
dihydrobenzofuran	68298-46-4
Designated Mixture
Aromatic C8 fraction from petroleum refining: The C9
fraction is primarily composed of
1,2,3,-trimethylbenzene (CAS No. 526-73-8),
1.2.4-trimethylbenzene	(CAS No. 95-63-6),
1.3.5-trimethylbenzene	(CAS No. 108-67-8), mixed
trimethylbenzenes (CAS No. 25551-13-7), ortho-
ethyltoluene (CAS No. 611-14-3), meta-ethyltoluene
(CAS No. 620-14-4), para-ethyltofuene (CAS No.
622-14-4), and mixed ethyltoluenes (CAS No.
25550-14-5) in varying proportions.
SUBSTANTIAL RISK ... SECTION 8(e|
Under section 8fe) persons who obtain new information
which reasonably supports the conclusion that a sub-
stance presents substantial risk of injury to human
health or the environment must notify EPA within 15
days. These notices are then reviewed by OTS and an
initial evaluation is prepared containing, if appropriate,
followup questions to the submitter, referrals to other
agencies, and recommended OTSIEPA followup actions.
The 8(e) notices represent a company's first review of a
situation and a judgment in compliance with the statute
to submit a notice within 15 days of obtaining the infor-
mation. EPA publishes its evaluations of these notices
to make this section 8(e) information widely available
and understandable to a broad public. The submissions
and the initial evaluations are located in the OTS Public
Reading Room, first floor, East Tower, Waterside Mall,
401 M Street, SW, Washington, D.C.
Persons wishing to obtain a copy of section 8(e) notices
may write: EPA, Freedom of Information, Ms. Jerri
Green, (A-101), Washington, D.C. 20460. There is no
charge for duplicating the first 49 pages, but at page 50
of a request for duplication there is a $10.00 fee and a
200 charge for each additional page (e.g., 51 pages cost
$10.20).
Single copies of the 8(e) initial evaluation (not the full
submission) are available from the TSCA Assistance
Office.

SUPPORT ACTIVITY
OTS Seeks MMT Information
The Office of Toxic Substances (OTS) is seeking infor-
mation from the public about methylcyclopentadienyl
manganese tricarbonyl (MMT) (CAS 12108-13-3) for a
Chemical Hazard Information Profile (CHIP), which it is
developing.
A CHIP is a brief summary of readily available informa-
tion concerning the health and environmental effects
and potential exposure to a chemical. CHIP candidates
are chosen on the basis of information indicating a po-
tential for adverse health or environmental effects
along with evidence of significant production or some
type of exposure.
When OTS searches the literature in preparing a CHIP it
generally limits the search to automated data bases and
reference works. But OTS encourages individuals and
firms to submit unpublished or recently published re-
ports, and all other hard-to-obtain studies on the chem-
ical selected for the CHIP. Relevant MMT studies from
the public could include data on health effects, environ-
mental effects, commercial production and uses, ex-
posed populations, environmental levels, or any other
material that can aid in the assessment of the chemi-
cal's impact on health or the environment. OTS is also
interested in knowing of current MMT testing or assess-
ment activities by other organizations.
Information about MMT should be immediately sent to:
TSCA Document Control Officer
TS-793
Attn: T. O'Bryan
Washington, D.C. 20460
The TAO continues to offer to notify individuals and or-
ganizations by letter every time OTS starts a new CHIP.
Persons who think they can aid the CHIP gathering
process will have their names added to the list if they
contact the TAO. All information submitted in response
to the solicitations will be placed in a public file and
made available for public inspection, unless the submit-
ter is able to assert a claim of confidentiality in accord-
ance with the provisions of section 14 of TSCA. EPA will
handle all confidentiality claims in accordance with its
procedures governing the confidentiality of business in-
formation (40 CFR Part 2 Subpart B).
The TAO is now distributing copies of the fol-
lowing recently completed CHIPs:

EPA Plans Asbestos Actions
Under TSCA, EPA plans in 1984 to propose a rule
banning certain asbestos product categories and that
would establish a staged production cap on all re-
maining asbestos uses.
This information was given to a U.S. Senate subcom-
mittee, on July 27, 1983, by Don R. Clay, Acting Assist-
ant Administrator, Office of Pesticides and Toxic Sub-
stances. A TSCA production cap on remaining asbestos
uses may start either as a proposed rule or as an ad-
vance notice of proposed rulemaking, Clay said.
The members of the Toxic Substances and Environ-
mental Oversight subcommittee were also told that the
Office of Toxic Substances (OTS) will soon begin to is-
sue risk management advisories (RMAs) on existing
chemicals. These nonregulatory advisories will focus
on specific problems with existing substances "and will
be used to encourage meaningful precautions," Clay
said. The RMAs will not be a substitute for rulemaking
but sometimes will be issued in connection with rule-
making activities, the Senators were told.
"One of the major objectives in the TSCA program dur-
ing the last two years was to get the existing chemicals
program off the ground," Clay said. An Existing Chemi-
cals Task Force is now in place and has reviewed 60
substances. Five of these chemicals have moved into
regulatory development and about 40 are targeted for
further analysis.
For new chemicals, the premanufacturing notice rule
(PMN) was postponed until September 10, 1983 to re-
spond to a petition by The Chemical Manufacturers As-
sociation and the Society of the Plastics Industry, Clay
told the subcommittee. EPA will publish a clarification
notice before that date.
A new chemicals Advisory Circular system will summa-
rize actions of specific categories of new chemicals or
describe specific PMN actions. "These circulars will
publicly advertise situations where EPA will likely need
more data in reviewing a PMN and as such will promote
early submission of such data," Clay said.
Other future TSCA new chemicals action will be in bio-
technology. "Biotechnology has until very recently
been a laboratory-scale phenomonon; however, com-
mercial uses potentially subject to TSCA regulations are
10

-------
now under development," Clay said. A copy of Clay's
testimony is available through the TAO.
DNA Chemicals Are Subject to TSCA
TSCA provides EPA with authority to regulate the prod-
ucts of biotechnology, including genetically engineered
organisms, according to Don R. Clay, the Acting Assist-
ant Administrator, Office of Pesticides and Toxic
Substances.
Clay testified before a subcommittee of the U.S. House
of Representatives on June 22, 1983. He said EPA does
not expect to see organisms containing genetically al-
tered DNA in wide industrial use for at least several
years.
But he cited two examples of why it is desirable to have
government review prior to commercial production of
organisms containing altered DNA, as would occur
through the premanufacturing notice process of TSCA.
It is presently unknown, Clay said, "whether genetically
engineered organisms, releasd into the environment,
can be infective or toxic to humans or other organ-
isms." Another unknown "is the possibility that a ge-
netically modified organism could disrupt existing
ecosystems," he said. Clay indicated that TSCA could
cover those applications not covered by other laws
such as FIFRA (pesticides) and FDA (drugs).
Guidance Report Available
A new booklet "TSCA Priorities and Progress" is now
available through the TAO. The report updates the 1982
"Priorities for OTS Operation." It describes the Office's
progress in carrying out the TSCA agenda and new di-
rections for the future. The purpose of the booklet is to
provide internal guidance to the OTS staff. The report is
being made available to the public for the same pur-
pose. OTS welcomes comments from the public on any
aspect of the report.
Federal Agencies Sign Task Force Chater
EPA, the Consumer Product Safety Commission and the
Occupational Safety and Health Administration have
signed a charter formally establishing a Federal Asbes-
tos Task Force. Other potentially interested agencies
will be invited to join. The goals of the task force are to
develop Federal perception of the asbestos health haz-
ard and to recommend and coordinate further research
and regulatory actions by the participating agencies.
For several months, subcommittees of the task force
have been meeting and sharing asbestos information,
identifying areas for joint efforts and developing a con-
sensus position on the asbestos risk issues.
EPA Organizes Chemical Symposium
EPA has organized a symposium on "Safer Chemicals
Through Molecular Design." The September 11-15,
1983 conference will be held at the Hyatt Regency Crys-
tal City, in Arlington, Va. The meeting is sponsored by
the Society of Toxicology. The registration fee is $80,
but is waived for government employees. However,
preregistration is necessary for all attendees.
Session titles listed in the preliminary program include:
Increasing Safety by Reducing Absorption
—Increasing Safety by Modifying Biotransformation
Pathways and Kinetics
Reducing Hazards to Aquatic Organisms
—Quantitative Structure Activity Approaches to Re-
