1	INTRODUCTION	

This document provides an overview of the conditions of use (COUs) considered for the draft
formaldehyde risk evaluation, pursuant to the Toxic Substances Control Act (TSCA) section 3(4)
definition of "conditions of use" and TSCA section 3(2) definition of "chemical substance." EPA does
not intend to directly assess risk from any formaldehyde exposures occurring from non-TSCA uses (e.g.,
exposures from biogenic production of formaldehyde or uses excluded from the TSCA section 3(2)
definition of chemical substance, such as pesticides used for embalming and taxidermy as well as any
food, food additive, drug, cosmetic, or device) in the draft formaldehyde risk evaluation. However, EPA
did consider potential background exposures from non-TSCA uses, as appropriate, to help inform the
Agency's risk determination for formaldehyde under the TSCA conditions of use. This document also
presents an explanation of the scope of certain conditions of use of formaldehyde and explains EPA's
rationale for any changes to the scope of the risk evaluation after publication of the Final Scope for the
Risk Evaluation for Formaldehyde CASRN 50-00-0 {U.S. EPA, 2020, 10617344} (2020 Final Scope).

2	RISK EVALUATION SCOPE	

The TSCA draft risk evaluation of formaldehyde comprises several human health and environmental
assessment modules and two risk assessment documents—the environmental risk assessment and the
human health risk assessment. A basic diagram showing the layout of these modular assessments and
their relationships is provided in Figure 2-1. In some cases, individual assessments were completed
jointly under TSCA and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). These
modules are shown in dark gray.

2.1 Conditions of Use Included in the Draft Risk Evaluation	

The Final Scope for the Risk Evaluation for Formaldehyde CASRN 50-00-0 {U.S. EPA, 2020,
10617344} (2020 Final Scope) identified and described the categories and subcategories of COUs that

EPA planned to consider in the formaldehyde risk evaluation. TSCA section 3(4) defines "conditions of
use" (COUs) as "the circumstances, as determined by [EPA], under which a chemical substance is
intended, known, or reasonably foreseen to be manufactured, processed, distributed in commerce, used,
or disposed of." Table 2-1 presents all COUs for formaldehyde.

In this draft risk evaluation, EPA has edited the formaldehyde COUs listed in the 2020 Final Scope.
These edits reflect EPA's improved understanding of formaldehyde's COUs based on further outreach,
public comments received, and updated industry code names under the Chemical Data Reporting (CDR)
for 2020. These edits included (1) updated additions based on new reporting in CDR for 2020, (2) name
changes based on new industry codes used in CDR for 2020, and (3) changes based on EPA's further
understanding of non-TSCA uses for formaldehyde that were initially included as TSCA COUs for
formaldehyde in the 2020 Final Scope. EPA further examined some COU subcategories included in the
2020 Final Scope and determined that the subcategories were not formaldehyde COUs, either because
EPA determined that the uses are excluded from the TSCA section 3(2) definition of "chemical
substance" or that the uses are not actually circumstances under which formaldehyde is intended,
known, or reasonably foreseen to manufactured, processed, distributed in commerce, used, or disposed
of. These subcategories are further discussed in Section 2.3 and have been removed from this draft risk
evaluation.

EPA may further refine the description of the formaldehyde COUs included in the risk evaluation when
the Final Risk Evaluation for Formaldehyde is published based upon peer review and public comment.

Table 2-1 presents the revised COUs that were included and evaluated in this Draft Risk Evaluation for
Formaldehyde.

a Life Cycle Stage Use Definitions (40 CFR § 711.3)

-	"Industrial use" means use at a site at which one or more chemicals or mixtures are manufactured (including
imported) or processed.

-	"Commercial use" means the use of a chemical or a mixture containing a chemical (including as part of an article)
in a commercial enterprise providing saleable goods or services.

-	"Consumer use" means the use of a chemical or a mixture containing a chemical (including as part of an article,
such as furniture or clothing) when sold to or made available to consumers for their use.

-	Although EPA has identified both industrial and commercial uses here for purposes of distinguishing scenarios in
this document, the Agency interprets the authority over "any manner or method of commercial use" under TSCA
Section 6(a)(5) to reach both.

b These categories of conditions of use appear in the Life Cycle Diagram, reflect CDR codes, and broadly represent
conditions of use of Formaldehyde in industrial and/or commercial settings and for consumer uses.
c These subcategories reflect more specific conditions of use of formaldehyde.

2.1.1 Additions and Name Changes to Conditions of Use Based on Updated 2020 CDR
Reported Data

After the 2020 Final Scope, EPA received updated submissions under the 2020 CDR reported data. In
addition to new submissions received under the 2020 CDR, the reporting name codes changed for the

2020 CDR reporting cycle. Therefore, EPA is amending the description of certain formaldehyde COUs
based on those new submissions and new reporting name codes. Table 2-2 summarizes the changes to
the COUs based on the new reporting codes in the 2020 CDR. These changes are included in Table 2-1.

2.2 Activities Determined Not to Be Conditions of Use

Section 2.2.2 of the 2020 Final Scope explained that EPA determined that several uses of formaldehyde
were outside the scope of TSCA, such as pesticidal uses regulated under FIFRA. Among other things,
TSCA section 3(2) excludes from the "chemical substance" definition "any pesticide (as defined in
[FIFRA]) when manufactured, processed, or distributed in commerce for use as a pesticide," "tobacco or
any tobacco product," and "any food, food additive, drug, cosmetic, or device (as such terms are defined
in.. .the Federal Food, Drug, and Cosmetic Act (FFDCA). . .) when manufactured, processed, or
distributed in commerce for use as a food, food additive, drug, cosmetic, or device" (TSCA section
3(2)(B)(ii), (iii), (vi)).

When developing this draft risk evaluation, EPA concluded that some subcategories of the conditions of
use listed in the final scope are either excluded from the TSCA section 3(2) definition of "chemical

foreseen to be manufactured, processed, distributed in commerce, used, or disposed of. Therefore, EPA

These activities were removed from the scope of the risk evaluation for the following reasons:

•	Processing, incorporation into a formulation, mixture, or reaction product, "Other: Preservative
in all other chemical product and preparation manufacturing" was removed after EPA
determined that this is a pesticidal use under FIFRA. These preservative products meet the
definition of "pesticide" under FIFRA (7 U.S.C. § 136(u)) and are therefore excluded from the
TSCA section 3(2) definition of "chemical substance" when manufactured, processed, or
distributed in commerce for these uses. (Related: see Commercial Use, Laboratory Chemicals,
"specimenpreservation, medical samples, mortuary science " below.)

•	Industrial Use, Non-incorporative activities, "agriculture, forestry, fishing, and hunting" was
removed after EPA determined that this is not a circumstance under which formaldehyde is
intended, known, or reasonably foreseen to be used. Based on additional information provided by
the submitter of the 2016 CDR submission identifying this subcategory, EPA believes that the
correct interpretation of the submission is of an incorporative activity involving the use of
formaldehyde in the manufacture of animal feeds for agriculture and aquaculture/hatchery usage
(Bakelite EPA-HQ-QPPT-2018-0438-0134). Depending on the particular facts, use of
formaldehyde in animal feed meets the definition of a food, food additive, or drug under the
FFDCA (21 U.S.C. § 321) and is therefore excluded from the TSCA § 3(2) definition of
"chemical substance" when manufactured, processed, or distributed in commerce for that use.
For example, FDA currently regulates the use of formaldehyde as a food additive in the
manufacture of certain animal feeds under 21 CFR § 573.460 and as an animal drug (Formalin)
to control external parasites on hatchery fish and their eggs under 21 CFR § 529.1004.

•	Commercial and Consumer Uses, "Personal care products (covered by TSCA) " under the
"Laundry and dishwashing products; Personal care products (covered by TSCA) " was removed
because, upon further investigation, EPA did not identify any formaldehyde-containing personal
care products covered by TSCA. Many personal care products meet the definition of cosmetic,
drug, or device under the FFDCA (21 U.S.C. §321) and are therefore excluded from the TSCA
section 3(2) definition of "chemical substance" when manufactured, processed, or distributed in
commerce for those uses. As noted in the final scope document for formaldehyde, such products
subject to FDA's jurisdiction were excluded from the final scope and could include eyelash
adhesives, hair treatments, moisturizers, mouthwashes, hand cleaning creams, shampoos,
conditioners, deodorants, certain nail treatments, perfumes and fragrances, shaving creams, and
certain body cleansers containing synthetic detergents. EPA did not identify any formaldehyde-
containing personal care products covered by TSCA.

•	Commercial Use, "Food packaging" under the "Food packaging; Paper products; Plastic and
rubber products; Toys, playground, and sporting equipment" EPA determined that the "food
packaging" meets the definition of food additive under the FFDCA (21 U.S.C. § 321(s)) and is
therefore excluded from the TSCA definition of "chemical substance" when manufactured,
processed, or distributed in commerce for that use.

Version - March 2024

• Commercial Use, Laboratory Chemicals, "specimen preservation, medical samples, mortuary
science " were removed as listed examples because these terms encompass pesticidal uses under
FIFRA. Specifically, EPA has identified the following types of products as pesticides that are
exempt from the requirements of FIFRA: embalming fluids; products used to preserve animal or
animal organ specimens, in mortuaries, laboratories, hospitals, museums and institutions of
learning; and products used to preserve the integrity of milk, urine, blood, or other body fluids
for laboratory analysis (see 40 CFR 152.25(c); 53 FR 15952, 15977 (May 4, 1988)). These
products meet the definition of "pesticide" under FIFRA (7 U.S.C. § 136(u)) and are therefore
excluded from the TSCA section 3(2) definition of "chemical substance" when manufactured,
processed, or distributed in commerce for these uses. Other uses of formaldehyde as a laboratory
chemical remain within the scope of the TSCA risk evaluation, such as fixative use for slide
preparation. Formaldehyde can be used in commercial laboratories for microscope slide
preparation and is used to bind proteins in order to make cells or tissues more structurally solid
in the short term. For example, an animal cell may be mobile on a glass slide so a fixative that
contains formaldehyde could be applied to that slide, so the cell is no longer mobile. EPA has
determined that these fixative purposes are in scope because this use is considered non-
pesticidal. Use for slide preparation could potentially have a short-term fixative (non-
preservation) purpose if there is not also an intent to preserve the tissue for later analysis.

2.2.1 Industries Affected by Activities Determined Not to Be Conditions of Use

Section 2.2.2 of the 2020 Final Scope explained that EPA determined that several uses of formaldehyde
were outside the scope of TSCA or were not considered. EPA is making additional clarifications and
added details for certain uses outside the scope of TSCA based on public request to explicitly state
which uses will not be covered under the draft formaldehyde risk evaluation.

Aquaculture, Hatchery, and Animal Feeds

In the 2020 Final Scope, EPA explained TSCA section 3(2) excludes from the definition of "chemical
substance" "any food, food additive, drug, cosmetic, or device (as such terms are defined in Section 201
of the Federal Food, Drug, and Cosmetic Act [21 U.S.C. 321]) when manufactured, processed, or
distributed in commerce for use as a food, food additive, drug, cosmetic, or device." However, EPA did
not list specific examples regarding animal feeds or animal drugs. Therefore, EPA is explaining that the
use of formaldehyde in animal feed or as an animal drug meets the definition of a "food, food additive,
[or] drug," respectively, under the FFDCA (21 U.S.C. § 321), and is therefore excluded from the TSCA
§ 3(2) definition of "chemical substance" when manufactured, processed, or distributed in commerce for
that use. For example, FDA regulates the use of formaldehyde as a food additive in the manufacture of
certain animal feeds under 21 CFR § 573.460, and as an animal drug (Formalin) to control external
parasites on hatchery fish and their eggs under 21 CFR § 529.1004.

Embalming and Taxidermy

In the 2020 Final Scope EPA explained TSCA section 3(2) also excludes from the definition of
"chemical substance" "any pesticide (as defined in the Federal Insecticide, Fungicide, and Rodenticide
Act [7 U.S.C. 136 et seq.]) when manufactured, processed, or distributed in commerce for use as a
pesticide." Products intended for use as a preservative for biological specimens in embalming and
taxidermy are considered pesticides under FIFRA. EPA has identified the following types of products as
pesticides that are exempt from the requirements of FIFRA: embalming fluids; products used to preserve
animal or animal organ specimens, in mortuaries, laboratories, hospitals, museums and institutions of
learning; and products used to preserve the integrity of milk, urine, blood, or other body fluids for
laboratory analysis (see 40 CFR 152.25(c); 53 FR 15952, 15977, (May 4, 1988)). Because these
products meet the definition of "pesticide" under FIFRA (7 U.S.C. § 136(u)), such formaldehyde-

Page 14 of 32


-------
PUBLIC RELEASE - DO NOT CITE OR QUOTE
Version - March 2024

containing products are therefore excluded from the TSCA section 3(2) definition of "chemical
substance" when manufactured, processed, or distributed in commerce for these uses.

Because embalming and taxidermy products intended for preservation of biological specimens are
considered pesticides under FIFRA and because FIFRA has a specific exemption for pesticides used for
biological preservation under the circumstances described in 40 CFR 152.25(c), uses that fall within the
40 CFR 152.25(c) exemption from regulation under FIFRA are not covered by either the Office of
Pesticide Programs formaldehyde registration review under FIFRA or by EPA's Office of Pollution
Prevention and Toxics (OPPT) in this draft TSCA risk evaluation.

2.2.2 Biogenic Sources of Formaldehyde Not Considered as Conditions of Use

EPA does not consider biogenic formation of formaldehyde, such as emissions from trees, plants, and
soil microbes, to be conditions of use under TSCA section 3(4). The biogenic formation can
significantly contribute to total formaldehyde concentration in ambient air. For purposes of this draft
risk evaluation for formaldehyde, EPA considered these as background exposures that are accounted for
in the ambient air exposure assessment.

2.3	Certain Combustion Sources and Secondary Formation of
Formaldehyde

Formaldehyde can be emitted from many types of combustion. In indoor settings these can include
burning candles, tobacco smoke, fireplaces and household appliances. These sources can also include
tailpipe emissions (including cars, trucks and boats), emissions from outdoor fires (including wildfires,
prescribed fires and agricultural burning), and emissions from industrial sources. Some combustion
activities that produce formaldehyde could occur during the manufacture, processing, use or disposal of
another chemical substance(s) or mixture(s).

Significant concentrations of formaldehyde are also found in the environment due to secondary
formation of the chemical after degradation of other compounds, for example, when a different chemical
undergoes chemical reactions in the air and forms formaldehyde.

Because combustion and secondary formation are so abundant and likely result in co-occurring
exposures, this draft risk assessment could not practically or reasonably differentiate secondary
formation, formation from combustion, and direct released of formaldehyde with certainty for this draft
risk evaluation. Secondary formation and combustion are the largest contributor of formaldehyde to
ambient air and indoor air concentrations. A full quantitative evaluation of exposure and risk from
formaldehyde produced during secondary formation and combustion was not practicable and would
impede efforts to conduct a scientifically sound and fit-for-purpose evaluation under TSCA within
statutory timeframes. For purposes of this TSCA draft risk evaluation for formaldehyde, EPA
considered these as background exposures that are accounted for in the outdoor and indoor air exposure
assessment.

2.4	Additions to the Scope Pertaining to Exposure Pathways and Risks
Addressed by Other EPA-Administered Statutes

Section 2.6.3.1 of the 2020 Final Scope explained that EPA would not consider certain exposure
pathways and risks addressed by other EPA-administered statutes. As announced on June 30, 2021, EPA
no longer intends to exclude exposure pathways that are addressed under other EPA-administered
statutes or regulatory programs from the scope of TSCA risk evaluations. As further explained in the
preamble to the proposed rule, Procedures for Chemical Risk Evaluation Under the Toxic Substances

Page 15 of 32


-------
PUBLIC RELEASE - DO NOT CITE OR QUOTE
Version - March 2024

Control Act (88 FR 74292, 74299-74300, October 30, 2023), EPA has reconsidered the text of the
relevant statutory provisions, overarching statutory structure and context, and legislative history, and no
longer interprets the law to authorize exclusion of exposure pathways from the scope of TSCA risk
evaluations because other EPA offices have already or could in the future regulate those chemicals.
Accordingly, EPA is no longer excluding from the scope of the Draft Risk Evaluation for Formaldehyde
the exposure pathways described below and in Section 2.6.3.1 of the 2020 Final Scope.

Composite Wood Products under TSCA Title VI

EPA stated in the 2020 Final Scope that the Agency had determined that three types of composite wood
products (hardwood plywood, particleboard, and medium density fiberboard [including thin-medium
density fiberboard]), and laminated products currently regulated under the Formaldehyde Emission
Standards for Composite Wood Products final rule (40 CFR part 770, promulgated under TSCA Title
VI), would not be included in the scope of the risk evaluation. Since the 2020 Final Scope's publication,
EPA no longer intends to exclude exposure pathways that are addressed under other EPA-administered
statutes or regulatory programs from the scope of TSCA risk evaluations, therefore all composite wood
products, including those regulated under TSCA Title VI, are included in the draft formaldehyde risk
evaluation.

EPA has determined that excluding TSCA Title VI regulated composite wood products from the
formaldehyde risk evaluation would reduce the comprehensiveness of the risk evaluation and introduce
complexities and uncertainties due to the regulated vs. non-regulated materials that may be present in a
finished good in indoor environment. However, the Agency also recognizes that allocating exposures
due to emissions from finished goods in indoor environments might be difficult due to the monitoring
data available for this draft risk evaluation which does not necessarily reflect information after the
implementation of TSCA Title VI.

Regulated composite wood products under TSCA Title VI include hardwood plywood, medium density
fiberboard, and particle board. Some examples of certain wood product containing COUs may include

•	Commercial use in floor coverings; foam seating and bedding products; furniture & furnishings
including stone, plaster, cement, glass and ceramic articles; metal articles; or rubber articles;
cleaning and furniture care products; leather conditioner; leather tanning, dye, finishing,
impregnation and care products; textile (fabric) dyes; textile finishing and impregnating/surface
treatment products;

•	Commercial use in construction and building materials covering large surface areas, including
wood articles; construction and building materials covering large surface areas, including paper
articles; metal articles; stone, plaster, cement, glass and ceramic articles;

•	Consumer use in floor coverings; foam seating and bedding products; cleaning and furniture care
products; furniture & furnishings including stone, plaster, cement, glass and ceramic articles;
metal articles; or rubber articles;

•	Consumer use in construction and building materials covering large surface areas, including
wood articles; construction and building materials covering large surface areas, including paper
articles; metal articles; stone, plaster, cement, glass and ceramic articles.

Exposure Pathways from Ambient Air, Drinking Water, Onsite Releases to Land, Disposal and Soil

The draft formaldehyde risk evaluation does not exclude from its scope exposure pathways from
ambient air, drinking water, onsite releases to land, disposal and soil as described in Section 2.6.3.1 of
the 2020 Final Scope document. The conceptual model depicted in Figure 2-15 of the 2020 Final Scope
document has been updated in Figure 1-7 of the Draft Human Health Risk Assessment for Formaldehyde
to reflect the exposure pathways, exposure routes and hazards to human receptors from releases and
wastes from industrial, commercial, and consumer uses of formaldehyde that EPA considered in the
draft risk evaluation.

2.5 Clarification Regarding Consideration of Formalin and
Paraformaldehyde in the Draft Risk Evaluation

Formalin

Formaldehyde is a gas that is distributed in solution as formalin. Formalin is a formulation of
formaldehyde in aqueous solution and is composed of three components—formaldehyde, methanol, and
water. It occurs as a colorless liquid at room temperature. Therefore, formalin was assessed as a part of
the formaldehyde risk evaluation under the TSCA COUs as listed in Table 2-1. It should be noted that
certain uses of formalin, such as the use as an animal drug as defined in the FFDCA to control external
parasites on hatchery fish and their eggs, are excluded from the TSCA section 3(2) definition of
"chemical substance" and therefore not included in the Draft Risk Evaluation for Formaldehyde.

Paraformaldehyde

Paraformaldehyde was not assessed since it is considered a different chemical substance with a different
CAS number (30525-89-4), and not prioritized or included in the Final Scope of the Risk Evaluation for
Formaldehyde CASRN 50-0-0.

substances for risk evaluation; and conduct risk evaluations
on at least 20 high priority substances no later than three
and one-half years after the date of enactment of the Frank
R. Lautenberg Chemical Safety for the 21st Century Act.

Formaldehyde is one of the 20 chemicals EPA designated
as a High-Priority Substance for risk evaluation under
TSCA (£ . December 30, 2019). Designation of
formaldehyde as high-priority substance constitutes the
initiation of the risk evaluation on the chemical.

TSCA Title VI sets formaldehyde emission standards for
composite wood products (i.e., hardwood plywood,
medium density fiberboard, and thin-medium density
fiberboard) and requires that any component parts or
finished goods fabricated with composite wood products
use compliant panels that have met the emission standards
and been tested/certified by an EPA recognized TSCA Title
VI third party certifier. The TSCA Title VI program also
has provisions for labeling, recordkeeping, import

Emergency Planning and
Community Right-To-
Know Act (EPCRA) -
Section 313

EPCRA Section 313 - also known as the Toxic Release
Inventory (TRI) - requires annual reporting from facilities
in specific industry sectors that employ 10 or more full-
time equivalent employees and that manufacture, process or
otherwise use a TRI-listed chemical in quantities above
threshold levels. A facility that meets reporting
requirements must submit a reporting form for each
chemical for which it triggered reporting, providing data
across a variety of categories, including activities and uses
of the chemical, releases and other waste management (e.g.,
quantities recycled, treated, combusted) and pollution
prevention activities (under section 6607 of the Pollution
Prevention Act). These data include on- and off-site data as
well as multimedia data (i.e., air, land and water).

Formaldehyde is a listed substance subject to reporting
requirements under 40 CFR 372.65 effective as of Januarv
1, 1987.

authority to cancel pesticide registrations if either (1) the
pesticide, labeling, or other material does not comply with
FIFRA; or (2) when used in accordance with widespread
and commonly recognized practice, the pesticide generally
causes unreasonable adverse effects on the environment.

published (EPAHO-OPP-2015-0739).

Federal Food, Drug, and
Cosmetic Act (FFDCA) -
Section 408

FFDCA governs the allowable residues of pesticides in
food. Section 408 of the FFDCA provides EPA with the
authority to establish tolerances (rules that establish
maximum allowable residue limits), or exemptions from the
requirement of a tolerance, for pesticide residues (including
inert ingredients) on food. Prior to issuing a tolerance or
exemption from tolerance, EPA must determine that the
tolerance or exemption is "safe." Section 408(b) of the
FFDCA defines "safe" to mean a reasonable certainty that
no harm will result from aggregate exposures (which
includes dietary exposures from food and drinking water as
well as nonoccupational exposures) to the pesticide.
Pesticide tolerances or exemptions from tolerance that do
not meet the FFDCA safety standard are subject to
revocation under FFDCA section 408(d) or (e). In the
absence of a tolerance or an exemption from tolerance, or
where pesticide residues in food exceed an existing
tolerance limit, a food containing that pesticide residue is
considered adulterated and may not be distributed in
interstate commerce.

Formaldehyde is no longer exempt from the requirement
of a tolerance (the maximum residue level that can remain
on food or feed commodities under 40 CFR Part 180.
Subpart I)).

limitation achievable through the application of the best
system of emission reduction (BSER) which (taking into
account the cost of achieving reductions and environmental
impacts and energy requirements) EPA determines has
been adequately demonstrated.



Clean Air Act (CAA) -
Section 112(b)

Contains the original list of 189 hazardous air pollutants
(HAPs) that Congress added in 1990. Under 112(c) of the
CAA, EPA must identify and list source categories that
emit listed HAPs and then set emission standards for those
listed source categories under CAA section 112(d). CAA
section 112(b)(3)(A) specifies that any person may petition
the Administrator to modify the list of HAP by adding or
deleting a substance. Since 1990, EPA has both removed
HAPs from and added HAPs to the original list.

Formaldehyde is listed as a HAP ( ).

Clean Air Act (CAA) -
Section 112(d)

Directs EPA to establish, by rule, National Emission
Standards for Hazardous Air Pollutants (NESHAPs) for
each category or subcategory of listed major sources and
area sources of HAPs (listed pursuant to Section 112(c)).
For major sources, the standards must require the maximum
degree of emission reduction that EPA determines is
achievable by each particular source category. This is
generally referred to as maximum achievable control
technology (MACT). For areas sources, the standards must
require generally achievable control technology (GACT)
though may require MACT. Section 112(d)(6) requires EPA
to review, and revise, as necessary, (taking into account
developments in practices, processes and control
technologies) the emission standards every 8 years.

years of promulgating the NESHAP.



Clean Air Act (CAA) -
Section 183(e)

Section 183(e) requires EPA to list the categories of
consumer and commercial products that account for at least
80 percent of all volatile organic compound (VOC)
emissions in areas that violate the National Ambient Air
Quality Standards (NAAQS) for ozone and to issue
standards for these categories that require "best available
controls." In lieu of regulations, EPA may issue control
techniques guidelines if the guidelines are determined to be
substantially as effective as regulations.

Formaldehyde is listed under the National Volatile
Organic Compound Emission Standards for Aerosol
Coatings ("40 CFR Dart 59. subpart E). Formaldehvde has a
reactivity factor of 8.97 g 03/g VOC.

Clean Water Act (CWA) -
Section 311(b) (2)(A) and
501(a) of the Federal Water
Pollution Control Act.

Requires EPA to develop, promulgate, and revise as may be
appropriate, regulations designating as hazardous
substances, other than oil, which, when discharged present
an imminent and substantial danger to the public health or
welfare, including, but not limited to, fish, shellfish,
wildlife, shorelines, and beaches.

Formaldehyde is a designated hazardous substance in
accordance with Section 311(b) (2)(A) of the Federal
Water Pollution Control Act (40 CFR Sectic . see
43 FR 10474 (March 13. 1978)).

Safe Drinking Water Act
(SDWA) - Section 1412(b)

Every 5 years, EPA must publish a list of contaminants
that: (1) are currently unregulated, (2) are known or
anticipated to occur in public water systems (PWSs) and (3)
may require regulations under SDWA. EPA must also
determine whether to regulate at least five contaminants
from the list every 5 years.

Formaldehyde was identified on both the Third (2009) and
Fourth (2016) Contaminant Candidate Lists (CCL) (74 FR
51850. October 8. 2009) and (81 FR 81099. November 17.

Resource Conservation and
Recovery Act (RCRA) -
Section 3001

Directs EPA to develop and promulgate criteria for
identifying the characteristics of hazardous waste, and for
listing hazardous waste, taking into account toxicity,
persistence, and degradability in nature, potential for
accumulation in tissue and other related factors such
as flammability, corrosiveness, and other hazardous
characteristics.

Formaldehyde is included on the list of hazardous wastes
pursuant to RCRA 3001. RCRA Hazardous Waste Code:

Formaldehyde was assessed under a Priority Existing Chemical designation (designated March 5, 2002) in response to
occupational and public health concerns. The main industrial use of formaldehyde is for the manufacture of formaldehyde-
based resins, which are widely used in a variety of industries, predominantly the wood industry. Formaldehyde is also used
directly or in formulations in a number of industries including medicine-related industries (such as forensic/hospital
mortuaries and pathology laboratories), embalming in funeral homes, film processing, textile treatments, leather tanning, and
a wide range of personal care and consumer products. The concentrations of formaldehyde in these products range from 40%,
such as in embalming and film processing solutions, to < 0.2%, such as in the majority of cosmetics and consumer products
