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.
