Significant New Use
Under section 5(a)(2) EPA determines when certain uses of
chemical substances are significant new uses. A determi-
nation is made by a significant new use rule (SNUR) promul-
gated after considering all relevant factors. These factors
include the projected manufacturing (import) and process-
ing volume of the substance, the extent to which the sub-
stance's new use changes the type and form of exposure to
humans or the environment, the extent to which the sub-
stance's use increases the magnitude and duration of expo-
sure to humans or the environment, and the anticipated
manner and methods of manufacture, processing, distribu-
tion in commerce, use, or disposal of the substance. Under
section 5(a)(1)(B), persons must notify EPA at least 90 days
before manufacturing or processing a chemical substance
for a significant new use as determined by EPA. If the
substance is imported, the importer must comply with cer-
tification requirements of TSCA section 13. In addition, per-
sons who intend to export, for any purpose, a substance
that is subject to a proposed or promulgated SNUR must
notify EPA under section 12(b).
EPA proposes SNURs for chemical substances which are
on the TSCA chemical inventory. A SNUR may be proposed
in conjunction with a 5(e) order issued during the PMN
review period or may be proposed at any time following ad-
dition of a chemical to the chemical inventory. Section 5(e)
orders that allow use of a PMN substance under controlled
conditions are usually accompanied by a proposed SNUR
because the order applies only to the original submitter.
When the PMN submitter sends EPA a notice of commence-
ment of manufacture (see page 5) the Agency adds the PMN
substance to the chemical inventory. A SNUR is necessary
in order to assure that controls imposed by the 5(e) order
will also apply to anyone else who may decide to manufac-
ture or process the new chemical in question.
Section 5(e) Action Pending Development of Information
The Administrator may issue a section 5(e) order to take
effect at the end of the PMN review period. The order may
limit or prohibit manufacture (import), processing, distribu-
tion in commerce, use, or disposal of the PMN substance.
The action can be taken if information available to EPA is in-
sufficient to permit a reasoned evaluation of the risks, and
if the substance may present an unreasonable risk to either
health or the environment. A 5(e) order may also be issued if
there is insufficient information and the substance may be
produced in large quantities and may result in significant or
substantial human exposure, or substantial release to the
environment.
A 5(e) order can be a consent order or a unilateral order. In a
consent order EPA negotiates the terms of the order with
the company that submitted the PMN. The company agrees
to be bound by the order and waives its rights to file objec-
tions to the order. This waiver does not affect any other
rights that the company may have under TSCA. In a unilat-
eral order, EPA takes action to restrict or prohibit the
manufacture or use in commerce of the PMN substance.

REGULATION OF HAZARDOUS
SUBSTANCES .. . 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. Under 6(a), EPA is re-
quired to apply one or several requirements of the law to the
extent necessary to protect against the risk.
EPA Seeks Data on Risks of PCB Transformer Fires
EPA is seeking specific data on the risks posed by fires in-
volving electrical transformers that contain PCBs and how
to eliminate the risks. In a March 23, 1984 notice (49 FR
11070) the Agency asked that comments on the issues be
submitted by May 22, 1984. EPA may propose further con-
trol measures on the use of such transformers if the data
received indicates the need.
The Agency is asking the public for data in five general
areas: (1) the extent of the risks posed by PCB-transformer
fires: (2) the probability of PCB-transformer fires occurring,
and factors that increase this probability; (3) the formation
of polychlorinated dibenzofurons (PCDFs), and polychlori-
nated dibenzodioxins, (PCDDs) during fires; (4) the total
economic cost of such fires; and (5) the total cost and
benefits of additional EPA PCB-transformer regulations.
Comments and data should be submitted in triplicate to:
TSCA Public Information Office (TS-793), Office of Toxic
Substances, Environmental Protection Agency, Rm. E-108,
Washington, D.C. 20460. Comments should include the
docket number OPTS-62035.
EPA issued a final PCB rule on August 25, 1982 (47 FR
37342) that allowed the indefinite use of certain electrical
transformers containing PCBs. The Agency at that time
believed that fires including this equipment were rare.
However, since then, there have been two additional fires
involving PCB-Transformers. EPA now believes transformer
fires in or near buildings may pose a risk to humans from
the dispersion of toxic chemicals.
EPA has learned "the risks result from incomplete combus-
tion of PCBs by themselves and by the incomplete com-
bustion of PCBs mixed with certain of the common dilvants
(chlorinated benzenes)," according to EPA Deputy Adminis-
trator, Alvin Aim.
"Well-documented tests on laboratory animals show that
various levels of PCBs can cause reproductive effects,
developmental effects, skin lesions, and tumors," Aim said.
"By themselves, PCB combustion can result in the forma-
tion of polychlorinated dibenzofurans (PCDFs). Tests on
rats have shown PCDFs to be even more toxic than PCBs,
causing anemia and other blood problems. Mixed with
chlorinated benzenes, PCB fluid combustion can result in
the formation of polychlorinated dibenzodioxins (PCDDs).
PCCDs are a chemical family that includes the dioxin 2, 3, 7,
8-TCDO. Dioxin was found in soot samples taken after a
February 5,1981 fire and in the May 14, 1983 fire at the One
Market Plaza Office Building complex in San Francisco."
EPA to Take New Asbestos-in-Buildings Action
EPA, responding to a TSCA section 21 citizen's petition,
has begun new additional proceedings for abating asbestos
contamination in schools and other public buildings. Under
section 21 any person may petition EPA to initiate rule-
making to amend or to repeal any rule under sections 4, 6 or
8 of TSCA, or an order under sections 5(e) or 6(b)(2).
The Service Employees International Union, of the AFL-CIO,
petitioned EPA to (1) establish standards for determining
when friable asbestos-containing materials in schools are
hazardous: (2) establish requirements for corrective action
when triable asbestos containing materials are determined
to be hazardous; (3) establish requirements for inspection
and abatement of friable asbestos-containing materials in
public and commercial buildings; (4) establish standards for
the performance of abatement activities, including stand-
ards for the protection of persons performing such ac-
tivities. EPA granted, in substantial part, all of the petition.
In granting the petition, EPA Administrator William D.
Ruckelshaus said that "EPA is in full agreement with the
goals of the petition and intends to insure that human
health is protected to the fullest extent possible where
asbestos is concerned." However, Ruckelshaus continued,
"To date, the Agency has been unable to develop a general
rule tfiat will be appropriate for all friable asbestos-
containing situations in buildings. Nonetheless, EPA is
committed to examining regulatory approaches to address-
ing the abatement issue."
As a first step toward developing appropriate regulations,
the Agency will review written comments and convene a
public meeting to discuss regulatory and technical options
on how EPA should modify its asbestos-in-buildings pro-
gram. Written comments were to be received by April 23,
1984. The public meeting will be held on May 7, 1984 in
Washington, D.C.
In March 1979 EPA began a technical assistance program to
help schools identify and control friable asbestos-contain-
ing materials and in May 1982 issued a final rule on identifi-
cation and notification of friable asbestos-containing
materials in all public and private schools. Those schools
that find friable asbestos were required to keep records, in-
form employees, Parent-Teacher Associations, post
notices, and distribute a guide for reducing asbestos ex-
posure to custodial and maintenance personnel. The com-
pliance deadline was June 28, 1983. EPA is now taking
action against possible violations of the rule.
EPA Acts Against Noncotnplying School Districts
Civil complaints are being filed against school districts by
EPA for failure to meet the asbestos-in-school re-
quirements of TSCA. By mid April 1984 EPA inspectors had
visited over 2,500 schools in 788 school districts. Notices of
noncompliancce were sent to 303 school districts.
EPA issued several civil complaints. Speaking of the
$24,000 claim levyed against the first school district, EPA
Deputy Administrator Alvin Aim said "This action shows
that EPA will not hesitate to fine school officials anywhere
in this country who are negligent in telling parents about
any asbestos danger faced by their children."
A few days later on March 21, Don R. Clay, director of EPA's
Office of Toxic Substances told a House of Representatives
subcommittee that 693 recent school inspections found a
significant percent to be in violation. "Some of the viola-
tions, such as a failure to inspect and failure to notify
5
-------
parents or employees, are of particular concern to the Agen-
cy," Clay told the House members.
"In view of this relatively widespread noncompliance, the
Agency has begun to utilize, in a cautious and phased man-
ner, the remedies available to it under the Toxic Substances
Control Act. Since the inception of the regulatory program,
the Agency has issued over 300 notices of noncompliance
to violative Local Education Agencies (LEAs). These notices
inform the LEA of the violations found and give the LEA 30
days to achieve compliance. Where compliance is not
achieved the Agency may proceed to issue an administra-
tive civil complaint which proposes to assess a penalty.
This penalty may be rescinded in whole or in part, if the LEA
takes prompt action to come into full compliance. The
Agency has just recently entered the penalty assessment
stage of its regulatory program. Within the last week the
first six administrative civil complaints have been issued.
We anticipate that more administrative complaints will be
issued as other school systems fail to correct violations by
taking timely voluntary actions." By mid April the civil com-
plaints issued by EPA totaled 14.
REPORTING RULES
HEALTH AND SAFETY RULES . . . SECTION 8(d)
Section 8(d) authorizes EPA to promulgate rules that re-
quire manufacturers and processors of designated chemi-
cal substances and mixtures to submit lists and copies of
unpublished health and safety studies on those substances
and mixtures.
EPA Proposes 8(d) List Candidates
Five substances will be added to the 8(d) list if a proposed
rule [February 16,1984] (49 FR 5974)] becomes final. The five
chemicals are:
2-Methylpyridine
3-Methylpyridine
4-Methylpyridine
Methylpyridine
Maleic anhydride
109-06-8
108-99-6
108-89-4
1333-41-1
108-31-6
The data received by EPA will be used to support a more
detailed assessment of the health and environmental risks
of the chemicals.
Substantial Risk ... Section 8(e)
Under section 8(e) persons who obtain new information
which reasonably supports the conclusion that a substance
presents substantial risk of injury to human health or the
environment must notify EPA within 15 days. These notices
are then reviewed by the Office of Toxic Substances (OTS)
and an initial evaluation is prepared containing, if appropri-
ate, 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 information.
EPA publishes its evaluations of these notices to make this
section 8(e) information widely available and understand-
able 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 $10.00 fee and a 20$ charge for each
additional page (e.g., 51 pages cost $10.20).
Single copies of the 8(e) initial evaluation (not the full sub-
mission) are available from the TSCA Assistance Office.

These chemicals have been selected for preliminary assess-
ment review. Information should be sent as soon as possi-
ble to;
TSCA Document Control Office (TS-793)
ATTN: T. O'Bryan
Washington, D.C. 20460
Persons who have unpublished data about any of the chem-
icals, but who also want answers to questions prior to
responding should contact Justine Welch Schaetfer, of the
OTS Chemical Screening Branch, (202) 382-3470, as soon as
possible.
The OTS review of the chemicals when published will be in-
cluded in reports called Chemical Hazard Information Pro-
files (CHIPs). A CHIP is a brief summary of readily available
information concerning the health and environmental ef-
fects and potential exposure to a chemical. CHIP candi-
dates are chosen on the basis of information indicating a
potential for adverse health or environmental effects along
with the 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 reports and ail
other hard-to-obtain studies on the chemical selected for a
CHIP. Relevant studies from the public could include data
on health effects, environmental effects, commercial pro-
duction and uses, exposed populations, environmental
levels, or any other material that can aid in the assessment
of the chemical's impact on health or the environment. OTS
is also interested in knowing of current testing of a CHIP
candidate or assessment activities by other organizations.
The TAO will notify individuals and organizations by letter
every time OTS starts a new CHIP. Persons who think they
can aid the CHIP information-gathering process will have
their names added to the list if they contact the TAO. All in-
formation submitted in response to the solicitations will be
placed in a public file and made available for public inspec-
tion, unless the submitter is able to assert a claim of con-
fidentiality, in accordance with the provisions of section 14
of TSCA. EPA will handle all confidentiality claims in ac-
cordance with its procedures governing the confidentiality
of business information.
The TAO is distributing copies of

TSCA Fact Sheet: Leaking Underground Storage Tanks
(April 1984)
Background The U.S. Environmental Protection
Agency is actively concerned with
the potential problem of leaking
underground and aboveground
storage tanks and pipelines. Toxic
materials leaking from such sources
may contaminate many environmen-
tal components, including ground-
water used for drinking, thus posing
a public health hazard. Presently,
anecdotal information has come to
the attention of the Agency indi-
cating that there has been this type
of environmental contamination in
certain limited areas of the United
States.
The authority The Agency is currently studying
the different environmental laws it
administers to determine which
would be the most appropriate to
study and potentially regulate this
situation. The Toxic Substances
Control Act (TSCA) is among the
Scope of problem
Present activities
laws under consideration. The Office
of Toxic Substances, (OTS), which
administers TSCA, has been working
on this situation since November
1983.
The EPA preliminary review indi-
cates that the leaking underground
storage tank problem has the poten-
tial to be widespread in scope. The
major Agency focus at this time is
on engine fuel storage tanks, but
EPA is also considering other stored
materials. The OTS preliminary
perspective does, however, exclude
hazardous waste storage tanks,
which will be regulated under the
Resource Conservation and Recov-
ery Act. This law also is adminis-
tered within EPA.
The following activities are under-
way concurrently:
—Information Collection—Presently
most of EPA's activities are in
this area. The Agency is gathering
information to determine the

scope of the problem. Particular
emphasis is being placed on data
from the EPA regional offices, the
States, consultants, companies
and trade associations. Groups
having data are invited to submit
the information to the TSCA
Assistance Office, Office of Toxic
Substances, TS-799, Washington,
D.C. 20460.
—Survey Development—The Agency
plans to conduct a survey of fuel
storage tanks to determine the
age of tanks and presence of
leaks. Data needed to develop a
sampling frame and subsequent
statistical survey design are being
obtained.
— Inventory of Tank Measurement
Methods—Information regarding
the available methods to test
storage tanks for leaks is being
obtained.
— Environmental Fate Modeling-
Data and predictive modeling
techniques are being compiled to
describe transport and transfor-
mations of materials leaking into
soils and groundwater.
An EPA plan of action is now going
through internal review.
Consideration is being given to mak-
ing the survey of underground gaso-
line storage tanks a priority issue.

A videotape on how to correctly complete PMN forms
is now available on a short-term loan basis. The TAO
is lending the 18-minute tape, which is an overview of
the process and a step-by-step explanation of the
form filling procedure. An instruction manual and a
transcript of the tape are included in the package.
The tape and printed material can be reproduced so
long as the lending period is not extended.
Two other tapes and transcripts on the PMN process
are also being lent by the TAO. Commonly asked
questions regarding PMNs are included in "Ques-
tions and Answers About the Pinal PMN Rule." This
21-minute tape covers research and development
exemptions, confidential business information and
the EPA review process. Also available is a 44-minute
tape of the Office of Toxic Substances' 1983 PMN
seminar. This "PMN Seminar Highlights" explores
the diverse positions of environmentalists, labor and
the chemical industry on the PMN rule. EPA officials
also present policy decisions.
