Environmental Protection Agency (EPA).
Withdrawal of proposed rule.
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.Start Further Info

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 Start Printed Page 71525sewer 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® 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® protective coveralls. In the 1987 study, acrylamide was found on dermal exposure monitoring pads placed inside the Tyvek® protective coveralls and against the skin of workers engaged in both sewer line and manhole sealing activities. This finding indicates that Tyvek® 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 Start Printed Page 71526effective 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® 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® 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®.
a. Concerns regarding the use of Tyvek® suits for dermal protection from acrylamide grout. The following information is drawn from EPA documentation (Ref. 7). Tyvek® is a proprietary, porous non-woven polyethylene fabric designed for disposable use as protection against exposure to dry particulate matter, not liquids. Because Tyvek® 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®, 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® 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® 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® 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® 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® against any liquid is to test the fabric against the liquid. EPA is unaware of any such tests of Tyvek® 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® protective overalls. The manufacturer of Tyvek® does not claim that it is an effective barrier against liquid acrylamide solutions. While it is possible that PPE made with Tyvek® may be effective in some situations for use with certain liquid chemicals, it appears unlikely that PPE made with Tyvek® 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® SL suit, along with nitrile gloves of an appropriate thickness (Ref. 7). Tychem® SL is a nonporous laminate of Tyvek® and Saranex® 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 Start Printed Page 71527which 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® 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.

Other documents relevant to this action can be found in docket OPPTS-62089, which is the docket for the proposed ban on acrylamide and NMA.
