The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
Summary 
This report summarizes the Toxic Substances Control Act (TSCA) and the major regulatory 
programs dealing with chemical production and distribution in U.S. commerce. The text is 
excerpted, with minor modifications, from the corresponding chapter of CRS Report RL30798, 
Environmental Laws: Summaries of Major Statutes Administered by the Environmental Protection 
Agency, coordinated by David M. Bearden, which summarizes more than a dozen environmental 
statutes. Issues related to TSCA implementation are addressed in CRS Report RL34118, The 
Toxic Substances Control Act (TSCA): Implementation and New Challenges, by Linda-Jo 
Schierow. 
The President’s Council on Environmental Quality proposed comprehensive federal legislation in 
1971 to identify and control potentially dangerous chemicals in U.S. commerce that were not 
adequately regulated under other environmental statutes. President Ford signed TSCA into law on 
October 11, 1976. Subsequently, five titles were added to address specific concerns—asbestos in 
1986 (Title II, P.L. 99-519), radon in 1988 (Title III, P.L. 100-551), lead in 1992 (Title IV, P.L. 
102-550), environmental and energy issues in schools in 2007 (Title V, P.L. 110-140), and 
formaldehyde emissions from composite wood products in 2010 (Title VI, P.L. 111-199). In 2008, 
Congress added provisions to Title I, Section 6 and Section 12, banning certain activities with 
respect to elemental mercury (P.L. 110-414). 
TSCA authorizes EPA to identify potentially dangerous chemicals in U.S. commerce that should 
be subject to federal control. The act authorizes EPA to gather and disseminate information about 
production, use, and possible adverse effects to human health and the environment of existing 
chemicals, and to issue “test rules” that require manufacturers and processors of potentially 
dangerous chemicals to conduct and report the results of scientific studies to fill information gaps. 
For chemicals new to U.S. commerce, TSCA requires pre-market screening and regulatory 
tracking of new chemical products. 
If EPA identifies unreasonable risks associated with existing or new chemicals, TSCA requires the 
agency to initiate rulemaking to reduce risks to a reasonable level. EPA may regulate the 
manufacture, importation, processing, distribution, use, and/or disposal of chemicals. TSCA 
provides a variety of regulatory tools to EPA, ranging in severity from a total ban on production, 
import, and use to a requirement that a product must bear a warning label at the point of sale. 
However, TSCA directs EPA to use the least burdensome option that can reduce risk to a level 
that is reasonable, given the benefits provided by the chemical product or process. 
Title I of the original statute establishes the core program, directs EPA to control risks from 
polychlorinated biphenyls (PCBs), and bans certain activities with respect to elemental mercury. 
Title II directs EPA to set standards for asbestos mitigation in schools and requires asbestos 
contractors to be trained and certified. Title III directs EPA to provide technical assistance to 
states that choose to support radon monitoring and control. Title IV provides similar assistance 
with respect to abatement of lead-based paint hazards. Title V addresses environmental issues at 
schools, including energy efficiency. Finally, Title VI directs EPA to set standards for emissions 
of formaldehyde from composite wood products.

The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
Introduction 
The Environmental Protection Agency (EPA) is responsible for identifying and regulating toxic 
substances in U.S. commerce under the authority of the Toxic Substances Control Act (TSCA). 
This report defines key terms, provides a brief history of toxic substances control law, and 
describes key provisions of TSCA. In addition, this report lists several references for more 
detailed information about the act and provides a table that cross references sections of the U.S. 
Code with corresponding sections of the act. The report is descriptive rather than analytic, 
highlights key provisions rather than providing a comprehensive inventory of the act’s numerous 
sections, and addresses authorities and limitations imposed by statute, rather than the status of 
EPA implementation or other policy issues.  
Overview 
The Toxic Substances Control Act (15 U.S.C. 2601 et seq.) authorizes the EPA to screen existing 
and new chemicals used in manufacturing and commerce to identify potentially dangerous 
products or uses that should be subject to federal control. Both naturally occurring and synthetic 
chemicals are subject to TSCA, with the exception of chemicals regulated under other federal 
laws concerning food, drugs, cosmetics, firearms, ammunition, pesticides, tobacco, or mixtures. 
EPA may require manufacturers and processors of chemicals to conduct and report the results of 
tests to determine the effects of potentially dangerous chemicals on living things. Based on test 
results and other information, EPA must regulate the manufacture, importation, processing, 
distribution, use, and/or disposal of any chemical that presents an unreasonable risk of injury to 
human health or the environment. A variety of regulatory tools is available to EPA under TSCA, 
ranging in severity from a total ban on production, import, and use to a requirement that a product 
bears a warning label at the point of sale. TSCA directs EPA to use the least burdensome option 
that can reduce risk to a level that is reasonable, given the benefits provided by the chemical 
product or process.

The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
Federal legislation to control toxic substances was originally proposed in 1971 by the President’s 
Council on Environmental Quality. Its report, “Toxic Substances,” defined a need for 
comprehensive legislation to identify and control chemicals whose manufacture, processing, 
distribution, use, and/or disposal was potentially dangerous and not adequately regulated under 
other environmental statutes. The House and Senate each passed bills in both the 92nd and 93rd 
Congresses (in 1972 and 1973, respectively), but controversies over the scope of chemical 
screening prior to commercial production and distribution, level of costs, and the relationship to 
other regulatory laws stalled final action. Episodes of environmental contamination—including 
contamination of the Hudson River and other waterways by PCBs, the threat of stratospheric 
ozone depletion from chlorofluorocarbon (CFC) emissions, and contamination of agricultural 
produce by polybrominated biphenyls (PBBs) in the state of Michigan—together with more exact 
estimates of the costs of imposing toxic substances controls, opened the way for final passage of 
the legislation. President Ford signed the TSCA into law on October 11, 1976. The original 
legislation included a single title, which has since been designated Title I. 
TSCA (Title I) directs EPA to 
•  require manufacturers and processors to conduct tests for existing chemicals if 
(1) their manufacture, distribution, processing, use, or disposal may present an 
unreasonable risk of injury to health or the environment; or they are to be 
produced in substantial quantities and the potential for environmental release or 
human exposure is substantial or significant; (2) existing data are insufficient to 
predict the effects of human exposure and environmental releases; and (3) testing 
is necessary to develop such data (§4); 
•  prevent future risks through pre-manufacture screening and regulatory tracking 
of new chemical products (§5); 
•  control unreasonable risks already known, including risks from polychlorinated 
biphenyls (PCBs), as well as risks for existing chemicals that may be discovered 
in the future (§6); and 
•  gather and disseminate information about chemical production, use, and possible 
adverse effects to human health and the environment (§8). 
Authorization for appropriations for these activities and a state grant program for control of toxic 
substances in the environment expired on September 30, 1983, although appropriations for these 
programs have continued. 
In October 2008, Congress amended TSCA Title I when it enacted the Mercury Export Ban Act 
of 2008 (P.L. 110-414). It prohibits certain activities with respect to elemental mercury. 
Subsequently, five titles have been added to TSCA to address specific concerns—asbestos in 
1986 (Title II, P.L. 99-519), radon in 1988 (Title III, P.L. 100-551), lead in 1992 (Title IV, P.L. 
102-550), schools in 2007 (Title V, P.L. 110-140), and formaldehyde in 2010 (Title VI, P.L. 111-
199). Title II directs EPA to set standards for asbestos mitigation in schools, and requires asbestos 
contractors to be trained and certified. Title III directs EPA to provide technical assistance to 
states that choose to support radon monitoring and control. Title IV provides similar assistance 
with respect to abatement of lead-based paint hazards. Title V addresses environmental issues at 
schools, including energy efficiency. Finally, Title VI establishes limits on emissions of 
formaldehyde from composite wood products.

The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
Title I 
Testing of Chemicals 
Many chemicals, even some in widespread use, are not well characterized in terms of their 
potential health and environmental effects. One of the major goals of TSCA was to induce the 
development of test data by producers (i.e., manufacturers, importers, and processors) of 
chemicals in commerce. Section 4 of TSCA directs EPA to require the development of test data 
on existing chemicals when certain conditions prevail: (1) the manufacture, processing, distri-
bution, use, or disposal of the chemical “may present an unreasonable risk;” or (2) the chemical is 
produced in very large volume and there is a potential for a substantial quantity to be released 
into the environment or for substantial or significant human exposure. Under either condition, 
EPA must issue a rule requiring tests if (a) existing data are insufficient to resolve the question of 
safety, and (b) testing is necessary to develop the data. 
Because there were more than 55,000 chemicals in U.S. commerce at the time EPA was to begin 
developing test rules, Congress established a special interagency committee to help EPA 
determine which chemicals should be considered first, and to coordinate testing needs and efforts 
among government agencies. At least every six months the Interagency Testing Committee (ITC) 
must consider candidate chemicals for inclusion on a list of substances that the ITC recommends 
to EPA for development and promulgation of test rules. TSCA directs the ITC to “designate” a 
subset of chemicals on the list for EPA action within 12 months. The list can contain no more than 
50 “designated” chemicals at any time. When a chemical is designated, EPA has one year to 
respond by issuing a proposed test rule or a notice explaining why no testing is needed. 
TSCA requires the ITC to consider the following factors when it makes listing decisions: (1) 
quantity of the substance to be manufactured, (2) quantity of the chemical in environmental 
releases, (3) number of people who will be exposed occupationally and the duration of exposure, 
(4) extent of non-occupational human exposure, (5) similarity of the chemical to any other 
chemical known to present an unreasonable risk, (6) existence of data concerning environmental 
or health effects of the chemical, (7) the quantity of information to be gained by testing, and (8) 
the availability of facilities and personnel for performing testing. Chemicals known or suspected 
to cause or contribute to cancer, gene mutations, or birth defects are to be assigned a higher 
priority. In response to information that indicates “there may be a reasonable basis to conclude 
that a chemical ... presents or will present a significant risk of serious or widespread harm to 
human beings from cancer, gene mutations, or birth defects,” TSCA requires EPA action to 
prevent or reduce that risk or publication of a finding that the risk is not unreasonable. 
Pre-manufacture Notification for New Chemicals or Uses 
TSCA (§5) requires manufacturers, importers, and processors to notify EPA at least 90 days prior 
to producing or otherwise introducing a new chemical product into the United States. Any 
information or test data that is known to, reasonably ascertainable by, or in possession of the 
notifier, and that might be useful to EPA in evaluating the chemical’s potential adverse effects on 
human health or the environment, must be submitted to EPA at the same time. TSCA also requires 
EPA to be notified when there are plans to produce, process, or use an existing chemical in a way 
that differs from previously permitted uses, if the Administrator has determined by rule that new 
uses of the chemical may produce significant changes in human and environmental exposures and 
Congressional Research Service 
3 
The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
therefore require notification. The 90-day notice provides EPA with the opportunity to evaluate 
the chemical use and, if necessary, to prohibit or limit such activity before it occurs to prevent 
unreasonable risk of injury to human health or the environment. 
EPA has 45 days after notification (or up to 90 days if it extends the period for good cause) to 
evaluate the potential risk posed by the chemical. If EPA determines that there is a reasonable 
basis to conclude that the substance presents or will present an unreasonable risk, the 
Administrator must promulgate requirements to protect adequately against such risk. 
Alternatively, EPA may determine that the proposed activity related to a chemical does not 
present an unreasonable risk; this decision may be based on the available data, or, when no data 
exist to document the effects of exposure, on what is known about the effects of chemicals in 
commerce with similar chemical structures and used in similar ways. 
The purpose of EPA’s screening procedure is to identify potential hazards, and control them 
before use of a chemical becomes widespread. If data are inadequate to make an informed 
judgment and (1) manufacture, processing, distribution in commerce, use, or disposal may present 
an unreasonable risk; or (2) a chemical is to be produced in substantial quantities, and the 
potential for environmental release or human exposure is substantial or significant, EPA may 
issue a proposed order to prohibit or limit such activities until sufficient data are submitted. 
Although the legislative history of TSCA includes a presumption that testing of new products 
would take place before they were widely used, either as the chemical was developed, or as its 
markets grew, TSCA also forbids promulgation of blanket testing requirements for all new 
chemicals. This reflects concern that uniform testing requirements might stifle innovation in the 
chemical industry. Thus, EPA must decide which chemicals, or which categories of chemicals, 
warrant the costs of pre-market testing. EPA reviews approximately 1,000 new chemical 
manufacturing notices annually. 
Regulatory Controls for Hazardous Chemicals 
TSCA requires EPA to regulate manufacturing, processing, distribution in commerce, use, or 
disposal of a chemical if it will present an unreasonable risk of injury to health or the 
environment, and the risk cannot be reduced to a sufficient degree under another federal law 
administered by EPA. The alternative means available to EPA for controlling chemical hazards 
that present unreasonable risks are specified in Section 6 of TSCA. EPA has the authority to 
•  prohibit or limit the amount of production or distribution of a substance in 
commerce; 
•  prohibit or limit the production or distribution of a substance for a particular use; 
•  limit the volume or concentration of the chemical produced; 
•  prohibit or regulate the manner or method of commercial use; 
•  require warning labels and/or instructions on containers or products; 
•  require notification of the risk of injury to distributors and, to the extent possible, 
consumers; 
•  require record-keeping by producers; 
Congressional Research Service 
4 
The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
•  specify disposal methods; and 
•  require replacement or repurchase of products already distributed. 
EPA also may impose any of these requirements in combination or for a specific geographical 
region. However, EPA is required by TSCA to regulate only “to the extent necessary to protect 
adequately” against a risk, and to use the “least burdensome” regulatory approach, even in 
controlling unreasonable risks. 
Two chemical substances are directly addressed in Title I: PCBs and elemental mercury. TSCA 
directs EPA to regulate PCBs and to ban most uses. In addition, TSCA prohibits the sale, 
distribution, or transfer of elemental mercury by federal agencies. 
Information Gathering 
Section 8 of TSCA requires EPA to develop and maintain an inventory of all chemicals, or 
categories of chemicals, manufactured or processed in the United States. The first version of this 
inventory identified approximately 55,000 chemicals in commerce in 1979. All chemicals not on 
the inventory are, by definition, “new” and subject to the notification provisions of Section 5. 
These chemicals must be added to the inventory if they enter U.S. commerce. Chemicals need not 
be listed if they are only produced in very small quantities for purposes of experimentation or 
research. 
To aid EPA in its duties under TSCA, the agency was granted considerable authority to collect 
information from industries. EPA may require maintenance of records and reporting of chemical 
identities, names, and molecular structures; categories of use; amounts manufactured and 
processed for each category of use; descriptions of byproducts resulting from manufacture, 
processing, use, and disposal; environmental and health effects; number of individuals exposed; 
number of employees exposed and the duration of exposure; and manner or method of chemical 
disposal. 
Manufacturers, processors, and distributors of chemicals are required to maintain records of 
significant adverse reactions to health or the environment alleged to have been caused by a 
substance or mixture. Records of adverse effects on the health of employees must be retained for 
30 years from the date of reporting. Industry also must submit lists and copies of health and safety 
studies. Studies showing adverse effects previously unknown must be submitted to EPA as soon 
as they are completed or discovered. 
Imminent Hazards 
Section 7 provides EPA authority to take emergency action through the district courts to control a 
chemical substance or mixture which presents an imminent and unreasonable risk of serious 
widespread injury to health or the environment. 
Relation to Other Laws 
Section 9 requires EPA to report cases of chemical risk to other federal agencies with the 
authority to prevent or reduce the risk. If the other agency determines that the activity does not 
present the risk described by EPA in its report, or initiates action under the law to protect against 
Congressional Research Service 
5 
The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
the risk, TSCA prohibits EPA from taking regulatory action with respect to such risk. For statutes 
under EPA’s jurisdiction, TSCA gives the Administrator discretion to decide if a risk can best be 
handled under the authority of TSCA. 
Enforcement and Judicial Review 
Section 11 authorizes EPA to inspect any facilities subject to TSCA requirements and to issue 
subpoenas requiring attendance and testimony of witnesses, production of reports and documents, 
answers to questions and other necessary information. Section 13 mandates TSCA enforcement at 
the national borders by the Treasury Department. 
Section 15 identifies acts prohibited under TSCA, while Section 16 describes penalties for acts 
violating these prohibitions, as well as recourse available to anyone accused of such violations. 
Section 16 authorizes civil penalties, not to exceed $25,000 per violation per day, and affords the 
defendant an opportunity to request a hearing before an order is issued and to petition for judicial 
review of an order after it is issued. Criminal penalties also are authorized for willful violations. 
Section 17 provides jurisdiction to U.S. district courts in civil actions to enforce TSCA Section 15 
by restraining or compelling actions that violate or comply with it, respectively. Chemicals may 
be seized and condemned if their manufacture, processing, or distribution violated the act. 
Section 19 authorizes any person to file a petition for judicial review of specified rules within 60 
days of issuance under TSCA. The court is directed to set aside specified rules if they are not 
supported by substantial evidence in the rulemaking record taken as a whole. 
Section 20 authorizes civil suits by any person against any person in violation of the act. It also 
authorizes suits against EPA to compel performance of nondiscretionary actions under TSCA. 
Section 21 provides the public with the right to petition for the issuance, amendment, or repeal of 
a rule requiring toxicity testing of a chemical, regulation of the chemical, or reporting. 
Confidential Business Information 
Section 14 provides broad protection of proprietary confidential information about chemicals in 
commerce. Disclosure by EPA employees of such information generally is not permitted, except 
to other federal employees, or when necessary to protect health or the environment. Data from 
health and safety studies of chemicals are not protected unless their disclosure would reveal a 
chemical process or chemical proportion in a mixture. Wrongful disclosure of confidential data by 
federal employees is prohibited, and may result in criminal penalties. 
Chemical Categories 
Section 26 allows EPA to impose regulatory controls on categories of chemicals, rather than on a 
case-by-case basis. However, EPA cannot regulate a group merely because it is composed of new 
chemical substances. 
Congressional Research Service 
6 
The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
State Preemption 
TSCA Section 18 preempts state actions that establish or continue in effect requirements 
applicable to a chemical substance or mixture that is regulated under TSCA Section 5 or 6, unless 
the state requirement is identical to the federal requirement, implements another federal law, or 
prohibits use of the substance or mixture within the state. However, a state may ask EPA to allow 
a state requirement that provides a significantly higher degree of protection from risk than does 
the federal requirement. 
Other Provisions 
TSCA Section 10 directs EPA to conduct and coordinate among federal agencies research, 
development, and monitoring that is necessary to the purposes of the act. 
Section 12 excludes chemical products manufactured for export from TSCA requirements except 
for reporting and record keeping requirements in Section 8. In 2008, Congress excluded 
elemental mercury from this exemption, banning its export beginning in 2013, with the exception 
of mercury contained in coal. Other exemptions for essential uses may be granted by rule. 
Section 22 waives compliance when in the interest of national defense. 
Section 23 provides protection of employees who assist in carrying out the provisions of the act 
(i.e., “whistle-blowers”). 
The potential effects of TSCA rules on employment must be monitored by EPA, according to 
Section 24. 
Section 25 mandates study of the need for indemnification of people affected by federal laws 
administered by EPA and of the feasibility of establishing a standard classification system for 
chemical substances and of storing and retrieving information about them. 
Section 26 authorizes data sharing and cooperative action to facilitate TSCA implementation 
between EPA and other federal agencies. It also authorizes collection of fees for EPA processing 
of data submitted in response to an order under Section 4 or 5. EPA is directed to establish an 
office to assist the regulated community. The agency also must establish a procedure to ensure 
disclosure of financial interests in the regulated community by EPA employees. Final orders 
issued under TSCA must contain a statement of basis and purpose. Finally, Section 26 established 
within EPA a new Assistant Administrator for Toxic Substances. 
TSCA Section 27 authorizes research and development of test methods for chemicals by the 
Public Health Service in cooperation with EPA. 
Grants to states are authorized by Section 28 to establish and operate programs to prevent or 
eliminate unreasonable risks to health or the environment. 
Section 29 authorized appropriations through 1983. 
An annual report is mandated by Section 30.

The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
Title II (Asbestos in Buildings) 
Growing public concern about the presence of potentially hazardous asbestos in buildings, 
especially in schools, led to congressional efforts to address this problem. Title II of TSCA, the 
Asbestos Hazard Emergency Response Act (AHERA), was enacted in 1986 (P.L. 99-519) and 
amended in July 1988 (P.L. 100-368). It required EPA to set standards by October 1987, for 
responding to the presence of asbestos in schools. The standards, set at levels adequate to protect 
public health and the environment, identify appropriate response actions that depend on the 
physical condition of asbestos. Schools, in turn, were required to inspect for asbestos-containing 
material, and to develop and implement a plan for managing any such material. Plans for 
managing asbestos were to be submitted by schools before May 1989, and implementation was to 
begin by July 1989. The law contains no deadlines for schools to complete implementation. 
Title II requires asbestos contractors and analytical laboratories to be certified, and schools to use 
certified persons for abatement work. Training and accreditation requirements also apply to 
inspectors, contractors, and workers performing asbestos abatement work in all public and 
commercial buildings. EPA may award training grants to nonprofit organizations for asbestos 
health and safety programs. However, authorization of appropriations for this grant program 
expired September 30, 1995. Other Title II requirements (such as mandates that buildings be 
inspected for asbestos) have not been extended to non-school buildings. 
To enforce requirements, TSCA authorizes EPA to take emergency action with respect to schools 
if school officials do not act to protect children. The act also authorizes citizen action with respect 
to asbestos-containing material in a school and to compel action by EPA, either through 
administrative petition or judicial action. Civil penalties not to exceed $5,000 are authorized for 
violations such as failing to conduct an inspection or to develop a school management plan. 
Concern about how schools would pay for required actions was addressed in separate legislation 
(the Asbestos School Hazard Abatement Act of 1984, or ASHAA, P.L. 98-377). It established a 
program offering grants and interest-free loans to schools with serious asbestos problems and 
demonstrated financial need. Although EPA for several years did not request funding for this 
program, Congress appropriated funds. Authorization of appropriations for this program expired 
September 30, 1995, and Congress has not appropriated funds since FY1993; a total of $382 
million in grant and loan funds were appropriated from FY1984 through FY1993. Repaid 
ASHAA loans are returned to an Asbestos Trust Fund, established in TSCA Title II, to become a 
dedicated source of revenues for future asbestos control projects. 
Title III (Radon Programs) 
In October 1988, Congress amended TSCA by adding Title III—Indoor Radon Abatement (15 
U.S.C. 2661 et seq., P.L. 100-551). The basic purpose of Title III is to provide financial and 
technical assistance to the states that choose to support radon monitoring and control; neither 
monitoring nor abatement of radon is required by the act. 
Title III required EPA to update its pamphlet “A Citizen’s Guide to Radon,” to develop model 
construction standards and techniques for controlling radon levels within new buildings, and to 
provide technical assistance to states. EPA is to provide technical assistance by establishing an 
information clearinghouse; publishing public information materials; establishing a national 
Congressional Research Service 
8 
The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
database of radon levels detected, organized by state; providing information to professional 
organizations representing private firms involved in building design and construction; submitting 
to Congress a plan for providing financial and technical assistance to states; operating cooperative 
projects with states; conducting research to develop, test, and evaluate radon measurement 
methods and protocols; developing and demonstrating new methods of radon measurement and 
mitigation, including methods that are suitable for use in nonresidential child care facilities; 
operating a voluntary program to rate radon measurement and mitigation devices and methods 
and the effectiveness of private firms and individuals offering radon-related services; and 
designing and implementing training seminars. The proficiency rating program and certification 
for training programs collect fees for service, and therefore are meant to be self-supporting, but 
Congress authorized $1.5 million to be appropriated to establish these programs. Congress 
authorized $3 million to be appropriated for each of three years beginning in 1989 for the other 
provisions of Sections 303, 304, and 305. 
A matching grant program was established for the purpose of assisting states in developing and 
implementing programs for radon assessment and mitigation. For this program, $30 million was 
authorized to be appropriated over three years, with funds targeted to states or projects that made 
efforts to ensure adoption of EPA’s model construction standards and techniques for new 
buildings; gave preference to low-income persons; or addressed serious and extensive radon 
contamination problems or had the potential to reduce risk or to develop innovative assessment 
techniques, mitigation measures, or management approaches. 
Other sections of Title III require EPA to conduct a study to determine the extent of radon 
contamination in schools; identify and list areas of the United States with a high probability of 
having high levels of indoor radon; make grants or cooperative agreements to establish and 
operate at least three regional radon training centers; and provide guidance to federal agencies on 
radon measurement, risk assessment, and remedial measures. 
All authorizations for appropriations specific to this title expired September 30, 1991, although 
appropriations have continued. 
Title IV (Lead Exposure Reduction) 
The 102nd Congress added Title IV to TSCA when it enacted the Residential Lead-Based Paint 
Hazard Reduction Act of 1992 as Title X in the Housing and Community Development Act of 
1992 (P.L. 102-550). TSCA Title IV aims to accelerate federal efforts to reduce risks to young 
children who daily are exposed to lead-based paint in their homes. In addition, it was intended to 
stimulate development of lead inspection and hazard abatement services in the private sector, 
while ensuring that the services provided and any products employed are reliable and effective in 
reducing risk. To these ends, Title IV directs EPA to 
•  promulgate definitions of lead-contaminated dust, lead-contaminated soil, and 
lead-based paint hazards; 
•  ensure that people engaged in detection and control of lead hazards are properly 
trained and that contractors are certified; 
•  publish requirements for the accreditation of training programs for workers; 
Congressional Research Service

The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
•  develop criteria to evaluate the effectiveness of commercial products used to 
detect or reduce risks associated with lead-based paint; 
•  establish protocols, criteria, and minimum performance standards for laboratory 
analysis of lead in paint films, soil, and dust; 
•  establish a program to certify laboratories as qualified to test substances for lead 
content; and 
•  publish and distribute to the public a list of certified or accredited environmental 
sampling laboratories. 
Title IV explicitly applies these requirements to federal facilities and activities that may create a 
lead hazard. 
In addition, Congress directed EPA to conduct a study of lead hazards due to renovation and 
remodeling activities that may incidentally disturb lead-based paint. EPA is required to 
promulgate guidelines for the renovation and remodeling of buildings or other structures when 
these activities might create a hazard. 
Title IV directs EPA to establish a clearinghouse and hotline to distribute information about the 
hazards of lead-based paint, how to avoid exposure and reduce risk, and new technologies for 
removing or immobilizing lead-based paint. In addition, Congress mandated development of a 
lead hazard information pamphlet; public education and outreach activities for health 
professionals, the general public, homeowners, landlords, tenants, consumers of home 
improvement products, the residential real estate industry, and the home renovation industry; and 
information to be distributed by retailers of home improvement products to provide consumers 
with practical information related to the hazards of renovation where lead-based paint may be 
present. 
Title IV authorizes states to propose programs to train and certify inspectors and contractors 
engaged in the detection or control of lead-based paint hazards. States also may develop the 
required informational pamphlets. TSCA requires EPA to promulgate a model state program that 
may be adopted by any state. Congress gave EPA the authority to approve or disapprove 
authorization for state proposals and to provide grants for states to develop and implement 
authorized programs. A federal program must be established, administered, and enforced by EPA 
in each state without an authorized program. 
The Department of Health and Human Services also has responsibilities under Title IV of TSCA. 
It mandates a study by the Centers for Disease Prevention and Control (CDC) and the National 
Institute for Environmental Health Sciences to determine the sources of lead exposure to children 
who have elevated lead levels in their bodies. The National Institute for Occupational Safety and 
Health is directed to study ways of reducing occupational exposure to lead during abatement 
activities. 
The act established a rule-making docket to ensure the availability to the general public of all 
documents submitted to agencies that are relevant to regulatory decisions pursuant to this 
legislation. The docket is required to include the drafts of all proposed rules submitted by EPA to 
the President’s Office of Management and Budget (OMB), written comments on the drafts, and 
written responses to comments. In addition, the agency must provide an explanation for any 
major change to a proposed rule that appears in the final rule, and such changes may not be made

based on information not filed in the docket. Dockets are required to be established in each EPA 
regional office. 
Congress authorized to be appropriated “such sums as may be necessary” for TSCA Title IV. 
In addition to amending TSCA, Title X of the Housing and Community Development Act of 1992 
authorized grants to states for risk assessments and lead-based paint removal and immobilization 
in private housing for low-income residents; establishing state training, certification, or 
accreditation programs for inspectors and abatement contractors; and research at the Department 
of Housing and Urban Development (HUD). Authorization for appropriations for these grants 
expired September 30, 1994, but appropriations have continued. Title X directed HUD to 
establish guidelines for federally supported work involving risk assessments, inspections, interim 
controls, and abatement of lead-based paint hazards. In addition, the National Institute for 
Occupational Safety and Health (NIOSH) was provided $10 million for training people who 
remove or immobilize paint. 
Title V (Reducing Risks in Schools) 
At the end of 2007, the 110th Congress added a fifth title to TSCA, subtitled Healthy High-
Performance Schools. Enacted as Title IV, Subtitle E (§461) of P.L. 110-140, the Energy 
Independence and Security Act of 2007, TSCA Title V authorizes EPA to establish a state grant 
program to provide technical assistance for EPA programs to schools and develop and implement 
state school environmental health programs. State programs must include standards for school 
building design, construction, and renovation, and identify ongoing school building 
environmental problems and recommended solutions. Environmental problems specifically 
mentioned in the law include “contaminants, hazardous substances, and pollutant emissions.” 
EPA’s authority to provide grants expires five years after the date of enactment. 
Title V requires the EPA Administrator, in consultation with the Secretary of Education and the 
Secretary of Health and Human Services, to issue voluntary guidelines within 18 months of Title 
V enactment for selecting sites for schools (presumably new schools). The guidelines are to 
account for the “special vulnerability of children to hazardous substances or pollution exposures 
in any case in which the potential for contamination at a potential school site exists,” modes of 
transportation available to students and staff, efficient use of energy, and potential use of a school 
at the site as an emergency shelter. 
Title V also requires the EPA Administrator, in consultation with the Secretary of Education and 
the Secretary of Health and Human Services, to issue voluntary guidelines within two years of 
enactment for developing and implementing state environmental health programs for schools. 
These guidelines must take into account the findings of federal initiatives established under 
“relevant federal law with respect to school facilities,” including initiatives related to water and 
energy conservation authorized by Sections 431 through 441, and work related to high-
performance green buildings authorized by Section 492 of P.L. 110-140. In particular, the 
guidelines must take into account “environmental problems, contaminants, hazardous substances, 
and pollutant emissions”; natural day lighting; ventilation; heating and cooling; moisture control 
and mold; maintenance, cleaning, and pest control; acoustics; and “other issues relating to the 
health, comfort, productivity, and performance of occupants of the school facilities.” In addition, 
Title V requires that the guidelines provide “technical assistance on siting, design, management, 
and operation of school facilities”; collaborate with children’s environmental health centers in 
Congressional Research Service 
11 
The Toxic Substances Control Act: A Summary of the Act and Its Major Requirements 
 
school environmental investigations”; assist states and the public to better understand and 
improve the environmental health of children; and take into account “the special vulnerability of 
children in low-income and minority communities to exposures from contaminants, hazardous 
substances, and pollutant emissions.” 
Several provisions in Title V refer to entities established under other sections of the Energy 
Independence and Security Act of 2007 (P.L. 110-140). For example, Title V contains directives 
for the Federal Director of the Office of Federal High-Performance Green Buildings in the 
General Services Administration, which was created by Section 436(a). In addition, there is 
reference to the national high-performance green building clearinghouse established in Section 
423(1) “to carry out public outreach to inform individuals and entities of the information and 
services [related to high-performance green buildings] available governmentwide.” Title V 
requires the Federal Director to ensure, “to the maximum extent practicable,” that the public 
clearinghouse “receives and makes available information on the exposure of children to 
environmental hazards in school facilities.” The EPA Administrator is directed to prepare an 
annual report to Congress on activities carried out under Title V authority, and this report also 
must be made available to the public through the clearinghouse. 
For the purposes of carrying out the provisions of Title V, Congress authorized appropriations of 
$1.5 million annually through 2013.  
Title VI (Limiting Formaldehyde Emissions) 
In July 2010, Congress enacted the Formaldehyde Standards for Composite Wood Products Act 
(P.L. 111-199), adding a new Title VI to TSCA. The new title mandates specific formaldehyde 
emission standards for hardwood plywood, medium-density fiberboard, and particleboard that is 
sold, supplied, offered for sale, or manufactured in the United States. The standards are phased in 
over two years from enactment and are based on the voluntary national formaldehyde emissions 
standards established by ASTM International (formerly known as the American Society for 
Testing and Materials), method ASTM E-1333-96 (2002).  
The standards apply to plywood, particleboard, and medium-density fiberboard in the form of an 
unfinished panel or incorporated into a finished good. Certain products are excluded, including 
many forms of lumber and panels used for outdoor applications, such as structural plywood, 
prefabricated wood I-joists, most windows, antiques or other previously owned goods, and 
composite wood products used inside automobiles, trucks, rail cars, boats, and aircraft. 
EPA is required to promulgate regulations ensuring compliance with the emission standards and 
must include provisions relating to labeling, chain of custody requirements, sell-through 
provisions; ultra low-emitting formaldehyde resins, finished goods, third-party testing and 
certification; auditing and reporting of third-party certifiers; recordkeeping; enforcement, 
laminated products; and exceptions for products and components containing “de minimis 
amounts” of composite wood products. The new law prohibits stockpiling of products 
manufactured before the effective date of the act for sale after that date. Also prohibited is any 
requirement for labeling products manufactured prior to the “designated date of manufacture.” 
P.L. 111-199 requires an annual report to Congress on the status of implementation and the extent 
to which relevant industries have achieved compliance. Finally, the act directs the Secretary of 
Housing and Urban Development to update regulations concerning formaldehyde emissions from
