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 existing chemicals—those
already in commerce and subject to TSCA—to test the
toxic effects of a designated substance. EPA can only
exercise this authority by rule and only when it has
made certain statutory findings about the named chem-
ical and when industry fails to develop the needed data
on its own. The findings must show that the named
chemical may present an unreasonable risk; that there
are insufficient data available with which to perform a
reasoned risk assessment; and that testing is necessary
ANPR ON PHENYLENEDIAMINES
On January 8, 1982, EPA published (47 FR 973) on
Advanced Notice of Proposed Rulemaking (ANPR) on
phenylenediamines, a class of chemicals recommended
for testing by the ITC. EPA, after analyzing comments
about phenylenediamines in the ITC's Sixth Report (45
FR 35897), and after reviewing other data, belives there
is reason to proceed with detailed consideration of the
ITC recommendation for testing of phenylenediamines.
THe purpose of the ANPR was to obtain more data,
which would help determine whether there is sufficient
risk to pursue regulatory control of phenylenediamines.
The comment period closed March 9, 1982.
to generate such data. A testing rule may also be based
on an EPA finding of substantial production and expo-
sure to humans or the environment, in addition to find-
ings of sufficient data and need for testing.
Under section 4(e) an Interagency Testing Committee
(ITC) was established to recommend chemicals to EPA
for priority testing under section 4. The ITC cannot
recommend more than 50 chemicals or categories of
chemicals for testing and must consider revising its list
every six months. The EPA Administrator must respond
within one year to each recommendation by starting
rulemaking under section 4 or giving reasons for not
doing so.
GROUP TO TEST CHLORINATED PARAFFINS
On January 8, 1982 (47 FR 1017) EPA published a
notice that it will not at this time propose a section 4(a)
rule to require health and environmental effects testing
of chlorinated paraffins. In the initial report of the Inter-
agency Testing Committee (ITC), transmitted to EPA on
October 4, 1977, the Committee recommended to the
EPA Administrator the chemical category "chlorinated
paraffins" for consideration for testing. Earlier that year,
an internatonal group of chlorinated paraffin manufac-
turers had formed a consortium to test their products for
both health and environmental effects. EPA has dis-
cussed the planned testing with the consortium and
finds the consortium's proposal to test chlorinated
paraffins voluntarily for their health and environmental
effects to be acceptable.

EPA REAFFIRMS DECISION ON ALKYL
PHTHALATES AND BENZYL BUTYL PHTHALATE
The TSCA Section 4(e) Priority List
On January 5, 1982, (47 FR 335) EPA said, after a
complete review of public comments, it found no reason
to alter its October 30, 1981 (46 FR 53775) decision not
to propose a section 4(a) rule to require environmental
or health effects testing of alkyl phthalates or benzyl
butyl phthalate. The October 30 decision was based on
EPA's acceptance of a comprehensive voluntary testing
proposal of phthalate esters from the Chemical Manu-
facturers Assocation (CMA) on behalf of the Phthalate
Esters Program Panel. The CMA proposal was offered as
an alternative to a test rule under section 4. On October
4, 1977 the Interagency Testing Committee (ITC) had
recommended the chemical category "alkyl phthalates"
for consideration for testing of environmental effects.
On October 24, 1 977 the ITC further recommended ben-
zyl butyl phthalates for environmental effects tests.
NINTH INTERAGENCY TESTING
COMMITTEE REPORT TO EPA
On October 30, 1981, the ITC sent its Ninth Report to the
EPA Administrator. This report, which was published on
February 5,1982 (47 FR 5456), revised and updated the
ITC priority of chemicals and added three chemicals to
the list for priority consideration by EPA in the promulga-
tion of test rules under section 4(a) of TSCA (see table).
The report also noted the removal of four entries from
the priority list. The three additions to the list are chlor-
endic acid, 4-chlorobenzotrifluoride and tris(2-chloro-
ethyl) phosphite. The new deletions are dichloro-
methane, nitrobenzene, 1,1,1-trichlorethane and the
alkyltin compounds.

COMMENCEMENT OF MANUFACTURE NOTICES
...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 or import. On May 15, 1979 (44 FR
28564) EPA published a statement of interim policy
concerning section 5, premanufacturing notification
(PMN). In the statement EPA said any person who sub-
mits a PMN under the interim policy and who (after the
90-day period) begins to manufacture or import the new
substance for commercial purposes must inform EPA on
or about the date when manufacture or import com-
mences, so that the Agency can add the substance to the
TSCA Inventory. This reporting requirement is imposed
under section 8(b). Listed below and on the next few
pages are the latest commencement of manufacture
notices EPA has received. To date about 30 percent of
PMNs that have passed through the review process
have been commercialized and therefore placed on the
Inventory.

STUDIES & SUPPORT ACTIVITY
NEW DIOXIN DATA
Data collected at five municipal burn sites indicate that
emissions of tetrachlorinated dioxin released by the
combustion of municipal wastes were not a "credible
health risk,'' according to an EPA spokesman.
The new evaluation called "interim" was based on tests
at municipal resource recovery plants in Arkansas, Flor-
ida, Illinois, Iowa, and Ohio. EPA estimates there are
about 40 such municipal burn sites in the United States,
with more coming on stream. The EPA interim data on
the emissions did not fully represent the industry, but
was an indication of current nationwide conditions and
what might be expected in the future.
Public concern over tetrachlorinated dioxin emissions
surfaced in the late 1970s because of a municipal re-
covery plant in Hempstead, NY. Data from that facility,
closed in 1979 because of an unrelated odor problem,
were not included in the EPA interim evaluation. In
releasing the emissions analysis, Dr. John W. Hernan-
dez, Jr., EPA's Deputy Administrator, said the approach
used in EPA's analysis was "extremely conservative, in
that the assumptions err on the side of public health
protection. The conclusions reached concerning public
health risks are likely to be applicable to similar facilities
when those facilities are properly designed, constructed
and operated."
NO NEW RULE REQUIREMENTS. AA SAYS
"EPA, under the Reagan Administration, will not create
new rule assignments that Congress never intended,"
Dr. John A. Todhunter recently told a farm industry
conference in Las Vegas. Todhunter, EPA's Assistant
Administrator for the Office of Pesticides and Toxic Sub-
stances, stated the policy at the Beltwide Cotton Produc-
tion and Mechanization Conference.
As EPA administers its mandate to prevent unreasona-
ble risks to humans and the environment under the
Reagan Administration, it will also seek to simplify the
regulatory load on the chemical industry and reduce
unnecessary costs to chemical users, Todhunter stated.
These ends will be attained by improving the quality of
assessments by EPA scientists and scientists employed
by the Agency's contractors.
"Throughout EPA, scientists are being appointed to
positions where scientific assessments and judgments
form the rationale for policy decisions," Todhunter told
the conference. For major EPA scientific studies, a peer
review system is to be created. "I was amazed that such
a system did not already exist at EPA. I believe that it is
unfair and unconscionably expensive to allow short cut
or unreviewed studies to become the basis for regula-
tory action," he said. Todhunter, sworn in on November
17, 1981, had been chairman of Catholic University's
biochemistry program.
Under the Agency's plan for a peer review program,
many EPA-sponsored reports and industry studies will
be reviewed by the Scientific Advisory Board before
major EPA decisions are taken.
In his speech, Todhunter said that EPA also has consi-
dered the use of voluntary and negotiated agreements
with industry to bring more flexibility to its regulatory
requirements. He pointed out that voluntary agree-
ments have many advantages. Long, formal rulemaking
processes can be avoided, test data can be more quickly
evaluated, and if warranted, Agency action can be
speedily started with voluntary agreements. "At the
same time, industry can save the costs associated with
formal rulemaking and will be involved from the begin-
ning in case-by-case decisions concerning tests to be
required," he said.
OTS DIRECTOR'S MESSAGE
In a recent message to the staff of the Office pf Toxic
Substances, Don R. Clay, the Director of OTS, provided
guidance on priorities for the OTS program.
Clay's priorities focused on three goals: "to provide bet-
ter guidance for OTS implementation of its new chemi-
cals and existing-chemicals programs, to develop more
cost-effective means for achieving industry compliance
with OTS policies, and to strengthen OTS operations."
OTS will focus on problems that are potential or actual
"significant risks" to health or the environment. Minor
risks "even if they could be controlled quickly or at little
cost will not be addressed." Better TSCA guidance will
be achieved, according to Clay, by having OTS meet all
statutory and court-ordered obligations, through estab-
lishing priority among discretionary TSCA authorities, to
state clearly the reason and assumptions for OTS deci-
sions, and to improve the scientific basis for OTS
decisions.
To achieve the cost-effective compliance goals, Clay
wrote, OTS employees should increase efforts to
achieve voluntary action by industry and eliminate
unnecessary burdens on industry caused by TSCA
actions. However, he told his staff to use TSCA authority
when voluntary action is inadequate.
To improve OTS internal operations, the staff manage-
ment capabilities must be strengthened. Clay also
emphasized better interaction with all government
agencies and improved OTS relations with industry,
labor, and public interest groups.
How OTS handles its new and existing-chemical pro-
grams is the key to TSCA, the Director stressed. PMNs
will be given high priority with meaningful reviews.
Submitter's will be required to give only essential infor-
mation, with requests for additional data as needed. A
PMN exemption process for low risk chemicals will be
developed by OTS and a follow-up program will place
bounds on risks associated with new
chemicals.
On existing chemicals, OTS will now concentrate on
reducing unreasonable existing health and environ-
mental risks by encouraging voluntary control by indus-
try and the public. To achieve this goal, OTS will focus on
evaluating specific problem areas and will seek to
exchange technical information with industry, labor
groups, and others early in the OTS evaluation.

AVAILABILITY OF TSCA RECORDS
Nonconfidential TSCA records and other information
relating to the Act's rulemaking activities are open for
public inspection in Room 106, East Tower at 401 M
Street, SW, Washington, DC.
Specifically the following types of TSCA records and
services are available for review:
— all official records of rulemaking and exemptions
(Sections 2, 4, 5, 6, 8, 12, 13, 20, and 21)
— premanufacture notifications
— trademark exemptions
— notices of substantial risk
— notices of export
— citizen's petitions
— civil actions
— indices and logs of records. (Many users find these
indices helpful because they provide an overview
of the information contained in the various records
and a system for locating the documents).
— a list of all manufacturers, and chemicals reported
to the TSCA Inventory, are available on micro-
fiche. The CICIS on-line data base may also be
used to obtain more specific inventory data.
— copies of all requests submitted under the Free-
dom of Information Act.
— photocopying facilities. (There is no charge for
duplicating the first 49 pages, but at page 50there
is a $ 10 fee and a 20C charge for each additional
page (i.e., 51 pages cost $10.20).
The Public Reading Room is open from 8 a.m. to 4 p.m.
Monday through Friday. Information specialists are
available to answer questions and assist visitors in their
review of documents. For further information call Ms.
Deborah A. Williams at 202-382-3602.
NEW NTIS PUBLICATION
An EPA contractor report, "Chemical Testing Industry:
Profile of Toxicological Testing," is now available from
the National Technical Information Service (NTIS). The
impetus for this report is the TSCA requirement that all
chemical substances that present unreasonable risks to
either health or the environment shall be tested for their
toxicological effects. The report provides an economic
profile of the toxicological testing industry, its supply
and demand attributes, and contains a list of laborato-
ries that service the chemical testing industry. To pur-
chase the report in hardback or microfiche, cite only the
NTIS number: PB 82-140773. Contact NTIS at (703-
487-4650) or:

REPORTS ON GLOBAL ENVIRONMENTAL
PROTECTION
Controlling hazardous chemicals is a global matter and
the United States government, through its officials and
through international cooperative ventures, is deeply
committed to protecting public health and the environ-
ment. For persons interested in the international aspect
of environmental protection and the part TSCA plays in
global matters, the IAO has the following materials:
* A speech on implementing chemical hazard eva-
luation within the framework of TSCA, presented
before a European Community meeting, in Rome,
by Dr. John A. Todhunter, the EPA Assistant
Administrator for Pesticides and Toxic Substances.
* Three December 1981 descriptions: on the World
Health Organization's International Program on
Chemical Safety; on the Organization for Economic
Cooperation and Development's "Chemical Pro-
gramme"; on the International Register of Poten-
tially Toxic Chemicals.
* A speech on PMN's under TSCA, presented at an
OECD Chemicals Forum in Paris by Don R. Clay,
Director, Office of Toxic Substances, EPA.
CONTENT CHANGE
This is the first issue of the TSCA Bulletin that does not
list the latest PMN notices received by EPA. This is an
economy move. Persons interested in obtaining the
PMN list can call the IAO toll-free number.
As announced on March 12, 1982 (47 FR 10900), the
Federal Register notices summarizing individual PMNs
and TMEs (test marketing exemption applications) will
now appear in an abbreviated format. However, the
notices will contain essentiallythe same information as
before.
PMN AIDS
The Office of Toxic Substances (OTS) has two support
programs for persons considering the submission of a
PMN or preparing the forms. Ms. Mary Cushmac, of the
OTS Notice Review Branch, will respond to PMN ques-
tions. She can be reached by telephone at (202-382-
3734), or by letter at TS-794, EPA, Washington, DC,
20460.
For persons within a 200-mile radius of either Chicago,
IL, or Summit, NJ, OTS has a PMN consultancy service
for small chemical manufacturers, importers and pro-
cessors. Triton Corporation, a Washington DC based
management consultancy firm, provides the service free
under contract with EPA. The Triton specialists have
backgrounds in industrial chemicals and were further
trained by the OTS personnel responsible for processing
and approving PMNs. The Triton specialists have been
cleared by EPA to handle Confidential Business Infor-
mation. Executives of firms in the Chicago area should
call Ms. Maricel Quintana at (314-454-0562). In the
Summit, NJ region, contact Mr. Alan Schneider at (201 -
277-0060), or 25 Glendale Road, Summit, NJ, 07901.
