Acrylamide and N-methylolacrylamide Grouts; Withdrawal of
Proposed Ban

AGENCY: Environmental Protection Agency (EPA).

ACTION: Withdrawal of proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is hereby withdrawing a proposed rule that would have
prohibited the manufacture, importation, distribution, and use of
acrylamide and N-methylolacrylamide (NMA) grouts. In 1991, EPA proposed
the rule in order to protect grouters from neurotoxic and carcinogenic
risks arising from significant dermal and inhalation exposure to the
acrylamide and NMA in these grouts. EPA found that grouters were
exposed when using these grouts, even while wearing the best practical
personal protective equipment (PPE) available at the time the rule was
proposed. EPA has found that there is now affordable PPE that provides
adequate protection from exposure to the acrylamide and NMA in these
grouts. EPA has determined that as long as appropriate PPE is used
during grouting operations, it is no longer necessary to prohibit the
use of these grouts to protect the health of grouters.

II. Background

A. What Action Did the Agency Propose to Take?

In 1991, EPA proposed to prohibit the manufacture, distribution in
commerce, and use of acrylamide grout (56 FR 49863, October 2, 1991)
(FRL-3767-7). In addition, EPA proposed to prohibit all uses of NMA
grout, except its use for

[[Page 71525]]

sewer line repair. EPA proposed to ban that use 3 years following
promulgation. EPA proposed that action because, based on the
information available to EPA at that time, EPA determined that it was
necessary to protect grouters (i.e., the individuals who routinely use
acrylamide and NMA grouts in the workplace) from the neurotoxic and
carcinogenic risks arising from significant exposures to the acrylamide
and NMA present in these grouts. EPA found that workers experienced
significant exposure even while wearing personal protective equipment
(PPE) (Ref. 1). For more information on acrylamide and NMA grouts and
their uses, see Unit II. of the preamble to the proposed rule. For more
information on the health effects of acrylamide and NMA, see Unit III.
of the preamble to the proposed rule. EPA issued the proposed rule
under the authority of sections 6(a) and 8(a) of TSCA. EPA based its
action on its determination that the use of acrylamide and NMA grouts
presented an unreasonable risk of injury to human health, and that a
prohibition of their manufacture, distribution in commerce, and use,
was the least burdensome action available to protect adequately against
these risks.

B. What Grouting Processes Were Covered by the Proposed Rule?

Grout is injected into and around concrete, rock, and soil to
strengthen its mass and restrict the flow of water. Following
application, the grout solidifies into a stiff, impervious gel.
Sewer rehabilitation is the major use of acrylamide and NMA grouts.
Sewer rehabilitation is discussed in this preamble as two separate
activities: sewer line sealing and manhole sealing. Both activities
seal cracks, holes, and joints in order to suppress infiltration of
rainwater, nonpoint source run-off, and ground water into sewer
systems. Preventing these inflows reduces demand on sewage treatment
capacity and wastewater treatment costs.
Sewer line sealing entails sealing main and lateral sewer line
pipes and joints using remotely operated equipment including closed-
circuit video cameras, an inflatable packer, and a grout delivery
system. The video camera is inserted into a sewer line and slowly
pulled through, transmitting images of the interior of the pipe to a
worker stationed at a control board inside a service truck. The worker
operates the packer from inside the truck to deliver the grout to seal
cracks and defective joints in the interior wall. The grout is forcibly
injected and flows through the crevices into the surrounding soil and
``gels,'' thereby sealing the fissures and preventing water
infiltration.
Manhole sealing is accomplished manually by a worker using a hand-
held device to inject grout into holes that have been drilled into the
sides of the manhole.

C. How are Workers Exposed to Acrylamide and NMA Grouts?

The following information is drawn from EPA's ``Assessment of
Airborne Exposure and Dermal Contact to Acrylamide During Chemical
Grouting Operations''; ``Regulatory Impact Analysis of the TSCA Section
6 Final Rule for Acrylamide Grout''; and ``Economic Analysis of a
Proposed Ban on Chemical Grouts Containing Acrylamide and N-
methylolacrylamide,'' and the related Addendums (Refs. 1, 2, 3, 4, and
5). Monitoring of acrylamide grouting operations conducted in 1987 by
EPA at four grouting sites, as well as the inherent nature of sewer
grouting work, established that workers were being dermally exposed to
acrylamide despite the use of PPE recommended at the time. A subsequent
field evaluation of acrylamide grouting operations by the Occupational
Safety and Health Administration (OSHA) (Ref. 6) also confirmed the
potential occurrence of significant exposures for workers using the
same recommended PPE. The following two sections describe exposures
experienced in different applications. Dermal exposures were invariably
the primary concern.
1. Dermal exposure--a. Manhole sealing. Sealing manholes presents
the greatest opportunity for dermal exposures because it is performed
with hand-held injection devices in tightly confined areas for extended
periods. Workers engaged in this process must be protected from
exposures to liquid acrylamide grout resulting from runoff and
splashes. Opportunities for exposure to liquid grout also occur during
mixing, gel testing, equipment disassembly, and clean up.
In the 1987 study, EPA measured dermal exposures of workers who
were sealing manholes while using the PPE recommended at the time,
including disposable Tyvek[reg] coveralls, eye goggles, half-mask air
purifying respirators, and rubber gloves. Workers sealing manholes
experienced dermal exposure ranging from 2.6 to 5.0 milligrams/hour
(mg/h).
b. Sewer line sealing. Sewer line sealing generates less of an
opportunity for dermal exposures because it is done with closed-circuit
video cameras and remotely controlled grout delivery systems, so that
little or no exposures occur during application. As with manhole
sealing, however, dermal contact can occur during mixing, gel testing,
equipment disassembly, and clean up.
EPA's 1987 monitoring study found dermal exposure levels in this
application ranging from 0.61 to 1.8 mg/h--less than one-third the
level experienced sealing manholes.
c. Effectiveness of Tyvek[reg] protective coveralls. In the 1987
study, acrylamide was found on dermal exposure monitoring pads placed
inside the Tyvek[reg] protective coveralls and against the skin of
workers engaged in both sewer line and manhole sealing activities. This
finding indicates that Tyvek[reg] coveralls are not an effective
barrier to acrylamide.
2. Inhalation exposure. Inhalation exposure to acrylamide and NMA
can occur during mixing, application, equipment disassembly, and clean
up. It may also occur when water from spilled solutions evaporates, and
the remaining dry powder becomes airborne. In EPA's 1987 field study,
monitored inhalation exposures to acrylamide ranged from one-fifth to
one-twentieth of measured dermal exposures. There was little variation
in inhalation exposures between sealing manholes and sealing sewer
lines; both applications generated virtually identical air
concentrations. Eight-hour time-weighted average (TWA) exposures within
the breathing zones of workers ranged from 0.008 to 0.12 mg/
m³. Three of the breathing zone samples exceeded the
American Conference of Governmental Industrial Hygienist's (ACGIH)
Threshold Limit Value (TLV), and the National Institute of Occupational
Safety and Health Recommended Exposure Limit (NIOSH REL) of 0.03 mg/
m³, although none exceeded the current 0.3 mg/m³
OSHA permissible exposure limit (PEL).

D. What is the Role of PPE in Protecting Workers?

Based on the 1987 field study described above, the Agency concluded
that even under the best of circumstances--in which informed and
motivated workers were properly using the best practical PPE and
practices available at the time the study was conducted--acrylamide
exposures would remain unacceptably high. In 2001, while preparing to
promulgate the proposed rule, EPA examined current data on PPE for use
with acrylamide and NMA grout to determine what equipment is currently
in use and whether equipment is available that can provide effective
and affordable protection for workers (Refs. 7, 8, 9, 10, 11, 12, 13,
and 14). EPA found that

[[Page 71526]]

effective and affordable equipment is now available, although it is not
yet in general use by grouting workers.
1. PPE currently being used with acrylamide grout may not be
effective. In the fall of 2001, EPA conducted a telephone survey to
determine what kind of protective equipment was being used by
acrylamide grout applicators (Ref. 14 ). EPA found that the most common
type of PPE used to prevent dermal exposure during acrylamide grouting
operations was a combination of Tyvek[reg] coveralls and gloves. Latex,
nitrile, and rubber were the most frequently reported glove types. This
type of PPE is the same as was being recommended and used in 1987 when
EPA conducted its field study (Ref. 1). In the EPA field study, dermal
exposure monitoring pads were placed under the Tyvek[reg] coveralls,
directly against the skin of the workers. In every case, acrylamide was
found on the dermal exposure monitoring pads at the end of the workday.
This finding indicates that acrylamide penetrated the Tyvek[reg].
a. Concerns regarding the use of Tyvek[reg] suits for dermal
protection from acrylamide grout. The following information is drawn
from EPA documentation (Ref. 7). Tyvek[reg] is a proprietary, porous
non-woven polyethylene fabric designed for disposable use as protection
against exposure to dry particulate matter, not liquids. Because
Tyvek[reg] is a porous fabric, the most important factor in determining
its effectiveness as a barrier to a liquid is the ability of the liquid
to penetrate the pores in the fabric. The ability of a liquid to
penetrate the pores is affected, in part, by the total amount of force
exerted on the liquid on the outer surface of the suit and by the
surface tension of the liquid. If enough pressure is applied to liquid
on the outer surface of Tyvek[reg], it can push the liquid through,
e.g., kneeling down while wearing a suit with acrylamide on the outer
surface of the suit could put enough pressure on the acrylamide to push
it through the suit.
In general, the lower the surface tension of a liquid, the easier
it is for it to pass through the pores of the fabric. Surface tension
causes a liquid to tend to contract to the smallest area possible. In
other words, a liquid with a high surface tension would tend to form
droplets on the surface of another material. Low surface tension
liquids on the other hand tend to spread out over the surface. Liquids
with sufficiently low surface tension can pass through the pores
without the application of external pressure. EPA has not been able to
find empirical data on the surface tension of aqueous acrylamide
solutions such as liquid acrylamide grout. EPA estimates, however, that
the surface tension of an aqueous acrylamide solution is well below the
level at which the manufacturer of Tyvek[reg] says liquids are likely
to penetrate the fabric.
The amount of liquid that gets on the fabric is also important,
particularly if the liquid has a low surface tension. When a porous
fabric such as Tyvek[reg] comes in contact with enough low surface
tension liquid, it can readily become saturated, even if the liquid is
in a mist form when it makes initial contact with the fabric.
Saturation of protective clothing such as a Tyvek[reg] suit may
actually increase the potential for dermal exposure, because it can
hold the liquid against the skin longer than would have occurred
otherwise.
Another concern involves the construction of Tyvek[reg] suits. The
seams of these suits are not generally sealed to prevent penetration by
liquids. Liquids can pass through gaps in the seams of such a garment
regardless of their ability to pass through the pores of the fabric.
This is particularly true of liquids which have low viscosity, such as
uncured acrylamide grout. Low viscosity fluids flow easily, and have
the ability to penetrate cracks and crevices such as the seams of an
unsealed garment.
The only way to be sure of the effectiveness of Tyvek[reg] against
any liquid is to test the fabric against the liquid. EPA is unaware of
any such tests of Tyvek[reg] against aqueous acrylamide solutions in
general, or acrylamide grout in particular, although in the 1987 field
study, acrylamide was found on dermal exposure pads worn inside
Tyvek[reg] protective overalls. The manufacturer of Tyvek[reg] does not
claim that it is an effective barrier against liquid acrylamide
solutions. While it is possible that PPE made with Tyvek[reg] may be
effective in some situations for use with certain liquid chemicals, it
appears unlikely that PPE made with Tyvek[reg] will be an effective
barrier against aqueous acrylamide solutions.
b. Concerns regarding the use of latex, nitrile, and generic
``rubber'' gloves with acrylamide grout. The following information is
drawn from EPA documentation (Ref. 7). EPA believes that gloves should
provide an effective barrier to acrylamide for a full work shift (at
least 8 hours) to be considered acceptable for use in acrylamide
grouting operations. A supplier of nitrile gloves reports that its 15
mil thick nitrile gloves are effective for at least 8 hours of exposure
to acrylamide (Ref. 9). Nitrile gloves that are too thin may not
provide adequate protection against uncured acrylamide grout over an 8-
hour period. Certain types of rubber gloves may be acceptable for
protection against uncured acrylamide grout, but other types may not
be. For example, it is likely that natural rubber, or latex will not be
effective for protection against uncured acrylamide grout, while butyl
rubber is more likely to provide adequate protection. Only testing of
the individual material and selected gauge will determine its
effectiveness against uncured acrylamide grout.
2. Effective and affordable PPE for acrylamide is now available. An
affordable and effective PPE combination for protection against dermal
exposure to acrylamide during grouting operations would be a PPE
product such as a Tychem[reg] SL suit, along with nitrile gloves of an
appropriate thickness (Ref. 7). Tychem[reg] SL is a nonporous laminate
of Tyvek[reg] and Saranex[reg] 23P film (Ref. 11). It is designed to
serve as a barrier to liquids and vapors. It is a widely available
material and has been tested by an independent laboratory and shown to
provide an effective barrier to acrylamide for 8 hours.
3. PPE for NMA. NMA grout is a chemical mixture consisting of about
90% NMA monomer and small amounts of acrylamide, formaldehyde, and
methylene bisacrylamide. In EPA's judgement, the structural properties
of NMA grout and acrylamide grout are sufficiently similar that
materials that provide an effective barrier against acrylamide are
likely to provide an effective barrier to NMA (Ref. 15).

E. Is the Use of Acrylamide Grout Related to the Finding of Acrylamide
in Cooked Food?

Earlier this year, the Swedish National Food Administration
reported that it had found acrylamide in certain foods (Refs. 19, 20,
and 21). Government agencies in Great Britain, Norway, and Switzerland
subsequently reported similar findings (Refs. 22, 23, 24, 25, 26, and
27). Detection of acrylamide in foods has also been confirmed by the
U.S. Food and Drug Administration (FDA) (www.cfsan.fda.gov). Acrylamide
was detected in fried and baked foods, but not in raw or boiled foods,
leading the researchers to conclude that acrylamide is formed during
the cooking process and is not present prior to cooking. The absence of
acrylamide in uncooked foods indicates that environmental contamination
from the use of acrylamide grout is not the source of the acrylamide.
FDA is working with other government agencies to coordinate research
related to assessment of risk from exposure to acrylamide. FDA is also
investigating the mechanisms by

[[Page 71527]]

which acrylamide is formed during the cooking process, and what steps
can be taken to minimize its formation. EPA has no evidence or reason
to believe that use of acrylamide grout is in any way related to the
acrylamide found in foods after cooking.

III. What Action is the Agency Taking Today?

A. Withdrawal of the Proposed Rule

EPA is withdrawing the 1991 proposal to ban the manufacture,
importation, distribution, and use of acrylamide and NMA grouts. This
action reflects the Agency's conclusion that affordable and effective
PPE is now available, and that workers who properly use such equipment
can be adequately protected while using acrylamide and NMA grouts. The
Agency no longer believes that it is necessary to ban acrylamide and
NMA grouts to protect workers.

B. Rationale for Withdrawal of the Proposed Rule

The 1991 proposed rule was based in large part on the determination
that, even when grouters used the best practical protective equipment
and techniques available at the time of the proposal, they were still
exposed to potentially significant levels of acrylamide and NMA. Given
the advancements in protective equipment and techniques that have
occurred since the 1991 proposed rule was issued, EPA has determined
that effective and affordable means of protecting grouters are now
available without banning the use of acrylamide or NMA.
On January 24, 2002, EPA met with the National Association of Sewer
Service Companies (NASSCO), and Avanti International Incorporated, the
sole supplier of acrylamide and NMA grouts in the United States (Ref.
16). EPA informed them of its findings concerning the inadequacies of
the PPE currently in general use in the industry and of the existence
of more suitable PPE. At the meeting NASSCO and Avanti International
expressed general agreement with EPA's findings and pledged to take
measures to incorporate the new information into their product
stewardship and worker safety programs.
Following the meeting, Avanti International modified its Safe
Operating Practices Program (SOPP) manual (Refs. 17, 18, and 28). The
revised manual recommends that employees who may be exposed to
acrylamide grout use protective clothing made from materials such as
Tychem[reg] SL which have been shown to be effective in laboratory
tests with acrylamide. The revised SOPP also recommends that workers
wear chemical resistant boots and gloves that have been shown to be
effective against acrylamide, and use full face respirators with P100/
organic vapor cartridges. The revised SOPP includes a checklist of
appropriate housekeeping procedures for workers to follow when handling
acrylamide grout. Avanti International has also developed a program
that addresses safe handling and mixing of chemical grouts, including
demonstrations of the recommended PPE and acrylamide grout mixing/
handling procedures (Ref. 28).
NASSCO stated that it has decided to develop an industry standard
guideline (ISG) on safe operating procedures for the use of acrylamide
grout (Refs. 17 and 18). The ISG is expected to adopt the
recommendations on PPE contained in Avanti International's SOPP. NASSCO
also stated that its guideline on safe operating procedures would be
referenced in a baseline standard for the application of chemical
grouts being developed by the American Society for Testing and
Materials (ASTM).
EPA welcomes these voluntary commitments by industry to improve
worker safety for grouters. EPA expects that as Avanti International
and NASSCO introduce and fully implement their revised programs, the
use of effective PPE and adherence to improved work practices will
become standard practice throughout the industry. EPA believes that the
best way to provide safety information to users of NMA and acrylamide
grouts is for grout suppliers to provide the information to their
customers through material safety data sheets (MSDSs), training
programs and other product stewardship efforts.
In view of the existence of affordable and effective PPE, and the
expectation that it will be generally adopted by the grouting industry,
EPA believes that it is not necessary at this time to promulgate the
proposed rule to protect grouting workers. EPA will continue to follow
Avanti International's and NASSCO's efforts and to encourage them to
make appropriate modifications to their worker safety programs. EPA
will monitor measures taken to protect workers in all sectors of the
grouting industry. If EPA determines that workers are not being
protected from exposure to acrylamide or NMA, it will reassess the
issue to determine whether further action is necessary.
