2,2-Dibromo-3-nitrilopropionamide; Toxic Chemical Release 
Reporting; Community Right-to-Know; Stay of Reporting Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Administrative stay; request for comment on petition to delist.

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

SUMMARY: EPA is granting a request submitted by the Dow Chemical Co. 
for an administrative stay of the reporting requirements under section 
313 of the Emergency Planning and Community Right-to-Know Act of 1986 
(EPCRA) and section 6607 of the Pollution Prevention Act of 1990 (PPA), 
for 2,2-dibromo-3-nitrilopropionamide (DBNPA)(Chemical Abstracts 
Service (CAS) No. 10222-01-2). This chemical was added to the 40 CFR 
part 372 Subpart D list of toxic chemicals in a final rule published in 
the Federal Register of November 30, 1994. Since promulgation of the 
final rule, the Agency has preliminarily determined that it categorized 
certain effects that supported the listing decision incorrectly. The 
effect of this stay is to suspend reporting on this chemical while the 
Agency completes its reassessment of the data for this chemical. The 
Agency has also received a petition to delist DBNPA based on new 
information. The Agency is making this information available for public 
comment and is seeking comment on whether DBNPA should remain on the 
EPCRA section 313 list of toxic chemicals. After evaluating public 
comment, the Agency will issue a final decision on the delisting 
petition which will either delete or retain this chemical on the 
section 313 list. In either case, the Agency's decision on the petition 
to delist will serve to dissolve this administrative stay. This action 
affects only EPCRA section 313 and PPA section 6607 toxic chemical 
reporting for DBNPA.

DATES: The administrative stay is effective October 27, 1995. Written 
comments on the petition to delist must be received by November 27, 
1995.

ADDRESSES: Written comments should be submitted in triplicate to : OPPT 
Docket Clerk (7407), TSCA Nonconfidential Information Center (NCIC), 
Office of Pollution Prevention and Toxics, Environmental Protection 
Agency, Rm. NE-B607, 401 M St., SW., Washington, DC 20460.

SUPPLEMENTARY INFORMATION:

I. Background

    Section 313 of the Emergency Planning and Community Right-to-Know 
Act of 1986, 42 U.S.C. 11023 (EPCRA) requires certain facilities 
manufacturing, processing, or otherwise using listed toxic chemicals to 
report their environmental releases of such chemicals annually. 
Beginning with the 1991 reporting year, such facilities also must 
report pollution prevention and recycling data for such chemicals, 
pursuant to section 6607 of the Pollution Prevention Act (42 U.S.C. 
13106). Section 313 established an initial list of toxic chemicals that 
was comprised of more than 300 chemicals and 20 chemical categories. 
Section 313(d) authorizes EPA to add to or delete chemicals from the 
list, and sets forth criteria for these actions. Under section 313(e), 
any person may petition EPA to add chemicals to or delete chemicals 
from the list. EPA has added and deleted chemicals from the original 
statutory list. Pursuant to EPCRA section 313(e)(1), EPA must respond 
to petitions within 180 days either by initiating a rulemaking or by 
publishing an explanation of why the petition has been denied.
    EPA issued a statement of petition policy and guidance in the 
Federal 

[[Page 54950]]
Register of February 4, 1987 (52 FR 3479), to provide guidance 
regarding the recommended content and format for petitions. On May 23, 
1991 (56 FR 23703), EPA issued a statement of policy and guidance 
regarding the recommended content of petitions to delete individual 
members of the section 313 metal compound categories. EPA has published 
a statement clarifying its interpretation of the section 313(d)(2) and 
(3) criteria for adding and deleting chemicals from the section 313 
toxic chemical list (November 30, 1994; 59 FR 61439).
    In the Federal Register of November 30, 1994 (59 FR 61432), the 
Agency published a final rule adding 286 chemicals and chemical 
categories to the EPCRA section 313 list of toxic chemicals. DBNPA was 
included among the 286 chemicals and chemical categories in the 
November 1994 final rule. The Agency found that DBNPA met the section 
313(d)(2)(B) criteria for chronic human toxicity because of chronic 
respiratory effects. (See 59 FR 61452).

II. Description of Request and Basis for Administrative Stay

    Since the promulgation of the final rule adding DBNPA to the list 
of toxic chemicals, it has been brought to the Agency's attention that 
it may have incorrectly categorized the effects observed in studies 
which were reviewed prior to promulgation. Some members of the 
regulated community have also expressed concern that the basis for the 
Agency's final action on this chemical was inadequately described in 
the rulemaking record.
    On December 29, 1994, Dow Chemical Co. requested that the Agency 
administratively stay the reporting requirements for DBNPA, based on 
their contention that the new information submitted with their request 
(which includes a study report dated August 2, 1994 and further 
analyses of studies in the record) demonstrates that the original basis 
for listing (chronic respiratory toxicity) is not valid (Ref. 1). 
Subsequently, on February 24, 1995, Dow Chemical Co. petitioned the 
Agency pursuant to EPCRA section 313(e) to delete DBNPA from the EPCRA 
section 313 list of toxic chemicals, contending that the new 
information submitted with the request for an administrative stay 
demonstrates that DBNPA does not meet the listing criteria (Ref. 2).
    Based on its reassessment of the information supporting the listing 
of DBNPA, EPA agrees preliminarily that DBNPA does not cause chronic 
respiratory toxicity. Therefore, the Agency believes that it is 
important and appropriate to administratively stay the effective date 
of the listing of this chemical.
    EPCRA section 313(d)(2) states that a chemical may be listed if any 
of the listing criteria are met. Therefore, in order to add a chemical, 
EPA must demonstrate that at least one criterion is met, but does not 
need to examine whether all other criteria are also met. Conversely, in 
order to remove a chemical from the list, EPA must demonstrate that 
none of the criteria are met. In reviewing the petition to delist DBNPA 
pursuant to EPCRA section 313(d)(3), EPA believes that DBNPA meets the 
criteria described in section 313(d)(2)(B), based on subchronic gastric 
toxicity; and the criteria described in section 313(d)(2)(C), based on 
environmental toxicity. Because the bases for meeting these criteria 
are different than those for which comments were originally received in 
response to the January 12, 1994 Federal Register notice, EPA is 
seeking comment on the initial determination for this chemical; the 
additional information which has been brought to the Agency's 
attention; and, generally, comments (and any supporting data) on 
whether the Agency should either grant or deny the petition to delete 
DBNPA.
    Under the November 1994 final rule, reporting for DBNPA is required 
to begin for activities during the 1995 calendar year, with the first 
reports due on or before July 1, 1996. However, because of the decision 
to issue this administrative stay, facilities will not have to prepare 
and submit Toxic Release Inventory (TRI) Form R reports for the 1995 
reporting year. Moreover, pending a decision by the Agency of whether 
to grant the petition and propose a rule to delete DBNPA or to deny the 
petition and affirm the listing, the reporting requirements of EPCRA 
section 313 and PPA section 6607 for DBNPA will continue to be 
administratively stayed. EPA's decision will be made promptly after 
consideration of public comment submitted on this Federal Register 
document.

III. EPA's Technical Review of the Petition

A. Chemistry/Use Profile

    1. Physical properties. DBNPA is a white, crystalline solid in its 
pure state. It has moderate water solubility (15 grams per liter (g/L)) 
and a very low vapor pressure at room temperature (less than 4 x 
10-5 mm Hg at 25  deg.C). DBNPA is degraded through hydrolysis in 
water, but this is a pH-dependent process which is most rapid under 
alkaline conditions (Ref. 4).
    2. Industrial uses. DBNPA is used as an algicide, bactericide, 
fungicide, and a preservative additive. The target microorganisms are 
coliform bacteria; slime- and odor-forming algae, bacteria and fungi; 
yeasts; and sulfide producing bacteria (as found in enhanced oil 
recovery applications). DBNPA's use as a pesticide is regulated under 
the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). It is 
used to control microorganisms in industrial water systems (such as 
cooling water and pulp and paper manufacturing); oil field 
applications; and a variety of products such as adhesives, glues, 
industrial coatings, metal cutting fluids, paints, emulsions, waxes, 
polishes, and inks. Currently, 26 companies have a total of 44 FIFRA 
registrations for DBNPA or products containing this chemical. At the 
present time, 80 percent of the total consumption of DBNPA in the U.S. 
(approximately 850,000 pounds in 1994) is in paper mills, 18 percent is 
used in recirculating water cooling systems and 2 percent is used in 
once-through cooling water systems. DBNPA is expected to be commonly 
used in rotation with other biocides in order to prevent acquired 
resistance by strains of the target organism or in combination with 
other biocides if there is a build-up of a particular organism. DBNPA 
is believed to be too expensive to be used as a primary biocide in many 
applications (Ref. 6).

B. Toxicological Evaluation of DBNPA

    1. Acute toxicity. EPA has reviewed the clinical signs, such as 
dyspnea, evidenced in 4- and 13-week rat studies by gavage. When EPA 
originally reviewed these studies for the November 1994 rule, EPA 
concluded that the effects observed in these studies represented 
chronic respiratory toxicity. Upon further analysis, EPA agrees with 
Dow Chemical's contention that the observed dyspnea was secondary to 
the method of treatment and that it is the result of acute irritation 
of the trachea and epiglottis due to reflux of the test material. 
Although some uncertainty exists as to the mechanism by which the 
dyspnea (and in some cases death) occurred, a NOEL (no observed effect 
level) of 5 milligrams per kilogram per day (mg/kg/day) and a LOEL 
(lowest observed effect level) of 13 mg/kg/day were established. DBNPA 
is corrosive, particularly to the eyes and, at least, is severely 
irritating to the respiratory tract (Refs. 3 and 7).
    2. Developmental toxicity. In a developmental study in rabbits, 

[[Page 54951]]
    developmental effects were reported at a dose of 30 mg/kg/day, with no 
evidence of maternal toxicity until the next higher dose (60 mg/kg/
day). Because the 30 mg/kg/day dose group was performed at a different 
time than the rest of the study (this group was initiated after the 
death of six rabbits) and did not have a concurrent control group for 
comparison, no statistical analysis can be validly performed. This 
treatment group cannot be considered as a valid part of the study 
(Refs. 3, 7, and 12).
    3. Chronic toxicity. As indicated above, a developmental study in 
rabbits showed evidence of maternal toxicity at a dose of 60 mg/kg/day. 
Deaths due to treatment were caused by ulcerative and hemorrhagic 
gastritis and occurred in 6 of 14 treated rabbits (dams). Evidence of 
effects did not occur immediately in the study, and deaths did not 
occur until after 10 days of dosing. These effects are considered to be 
subchronic in nature. Further support for the subchronic, rather than 
acute, nature of the effect is that in a range finding study in which 
rats were administered the test material by gavage at similar doses for 
up to 2 weeks, no gastritis was seen (except in one female at the end 
of 2 weeks treatment). Due to the deletion of the 30 mg/kg/day dose 
level from the evaluation of the developmental study, the maternal NOEL 
for this study has been reassessed as 10 mg/kg/day (no effects were 
observed at dose levels of 0 and 10 mg/kg/day), with a maternal LOEL of 
60 mg/kg/day (Refs. 3 and 7).
    4. Environmental toxicity. Only the 96-hour (h) EC50 (median 
effective concentration) of 0.300 mg/L (milligram per liter) for DBNPA 
was reported for freshwater green algae based on the growth rate. This 
result was based on nominal concentrations derived from a water-based 
stock solution used to initiate the test. Had this effective 
concentration been based on mean measured concentrations of the test 
substance during the test period, EPA believes that the EC50 
values would have been lower. Assuming a hydrolysis rate (t\1/2\) of 63 
hours at pH 7 (the pH of the algal medium was 7.5), concentrations were 
predicted at time (t)=0 h, t=63 h, and t=98.5 h and averaged. The mean 
concentrations were predicted to be 64 percent of the concentrations at 
t=0 h. Based on these predicted mean concentrations, EPA calculated the 
green algal 96-h EC50 as 0.010 mg/L. Saltwater green algal 
toxicity was not measured. The reported value for daphnid chronic 
toxicity is a LOEC (lowest observed effect concentration) of 0.020 mg/
L; this was the lowest dose tested. Using the dose-response curve data 
from the test report, chronic EC10 (ten percentile effective 
concentration) values were predicted for total mean young per female 
(0.005 mg/L) and for total young (0.008 mg/L). DBNPA slows oyster shell 
deposition and has a 48-h EC50 less than 0.070 mg/L. It is not 
known whether this is a direct effect of DBNPA on the oysters 
themselves or an indirect effect of DBNPA on oysters because of direct 
effects on oyster food sources, i.e., phytoplankton or saltwater green 
algae. Because the toxicity of DBNPA towards saltwater green algae was 
never measured, this issue could not be resolved (Refs. 8, 9, and 10).

C. Exposure to DBNPA in the Environment

    In making listing determinations under EPCRA section 313, there are 
limited circumstances under which it is appropriate for EPA to consider 
exposure factors (See 59 FR 61440). The Agency believes that exposure 
considerations are appropriate in making determinations (1) under 
section 313(d)(2)(A), (2) under section 313(d)(2)(B) for chemicals that 
exhibit low to moderately low toxicity based on a hazard assessment 
(i.e., those chemicals for which the value of listing on the EPCRA 
section 313 list on hazard alone is marginal), and (3) under section 
313 (d)(2)(C) for chemicals that are low or moderately ecotoxic or do 
not induce well-documented serious adverse effects. The Agency believes 
that exposure considerations are not appropriate in making 
determinations (1) under section 313(d)(2)(B) for chemicals that 
exhibit moderately high to high human toxicity based on a hazard 
assessment, and (2) under section 313(d)(2)(C) for chemicals that are 
highly ecotoxic or induce well-established adverse environmental 
effects. Based on its most recent reassessment, EPA has preliminarily 
determined that DBNPA is acutely toxic to humans, highly chronicly 
toxic to humans and highly ecotoxic.
    EPA has, as part of the review of DBNPA, conducted an exposure 
analysis. Based on a screening level assessment, EPA estimated the 
likelihood of exposure at facility boundaries at levels which are 
reasonably likely to cause acute toxicity. Further, because of 
uncertainties encountered initially regarding the degree of 
environmental toxicity of DBNPA, EPA also conducted an exposure 
analysis which estimated the likelihood of exposure to the environment. 
Because the analyses were conducted, the results of this environmental 
exposure analysis are presented below. However, the determination that 
the listing criterion of EPCRA section 313(d)(2)(C) is met is based 
solely on the hazard of the chemical, not on estimated exposures.
    Due to its very low vapor pressure, DBNPA is not expected to be 
released in significant quantities to air. Since DBNPA is manufactured 
and imported as a liquid and is soluble in water, land releases are 
also anticipated to be low. However, there is a concern for aqueous 
releases of DBNPA to the environment; especially from paper mills and 
cooling water systems (Ref. 10).
    1. Paper mills. There are a variety of applications for which DBNPA 
can be used in paper mills. DBNPA is used to control microorganisms 
which can grow in aqueous systems affected by machine deposits (such as 
starch, which acts as a nutrient) and other sources of biological 
contamination. Many of the additives used in this industry are 
preserved with biocides. DBNPA is continuously added at a rate of 0.03-
0.1 lb per ton of pulp or paper (on a dry basis) and it is assumed that 
DBNPA is used to treat the pulp or paper every day (Ref. 6). DBNPA's 
primary removal mechanism is hydrolysis, which is highly pH sensitive. 
At neutral pH, the overall removal during wastewater treatment 
operations with a total residence time of 12 hours is estimated to be 
15 percent (the typical pH of waste water treatment plants in the 
United States is 7.2). All of the DBNPA used within the mill is 
expected to be sent to on-site treatment or directly to a publicly 
owned treatment works (POTW) (Refs. 5 and 6).
    Based on these assumptions, EPA calculated the predicted releases 
of DBNPA daily at each site, stream concentrations at low and mean 
flow, and potential daily dose rates for human exposure to drinking 
water for a variety of paper mill operations. Based on this screening 
level assessment, EPA believes there is little to no likelihood for 
dyspnea associated with general population drinking water exposures in 
this use application. However, at the usage rate indicated, the 
concentration of concern for environmental effects on freshwater green 
algae and daphnids would be exceeded essentially every day throughout 
the year (364-365 days) (Ref. 10).
    2. Cooling water systems. Cooling systems are treated to maintain 
efficient heat exchange, to prevent plugging of orifices, to prevent 
potential health concerns and for aesthetics. Typical biocide 
treatments have use levels of less than 100 mg/L and the biocide may be 
added continuously or intermittently. There are an estimated 40,000 

[[Page 54952]]
recirculating open-water cooling systems in the U.S. (average size 
20,000 gallons) and an estimated 4,000 once-through water cooling 
systems with an average size of 1,000,000 to 20,000,000 gallons. 
Although there are far more recirculating than once-through systems, 
the total volume of water discharged from once-through towers is 
estimated to be approximately the same as from recirculating systems. 
In recirculating systems, DBNPA is used at a rate of 2.5-24 mg/L. DBNPA 
is used to treat the water 1-3 times per week throughout the year 
(Refs. 5 and 6). Based on the above usage rate and the estimated annual 
use of DBNPA in recirculating water cooling systems (153,000 lb/yr), 
the annual use of DBNPA is calculated at 64-640 lb/site-yr at 239-2,390 
sites. All of the DBNPA used in recirculating water cooling systems is 
expected to be sent to on-site treatment or directly to a POTW (Refs. 5 
and 6). Calculated at the maximum usage rate for DBNPA and the lowest 
stream flow, a screening level assessment similar to that conducted for 
paper mills demonstrated no likelihood for dyspnea to the general 
population (Ref. 10). For recirculating water cooling systems, the 
concentration of concern for environmental effects on freshwater green 
algae and daphnids would be exceeded 160 days per year (Ref. 10). The 
average use rate of DBNPA in once-through cooling systems is estimated 
at 200 pounds per site-year (lb/site-yr). DBNPA is used to treat the 
water less than 100 days during the year, which is an application rate 
of less than 2 lb/site-day. All of the DBNPA used in recirculating 
water cooling systems is expected to be sent to on-site treatment or 
directly to a POTW (Refs. 5 and 6). A screening level assessment 
indicated that there is little to no likelihood for dyspnea associated 
with general population drinking water exposures in this use 
application (Ref. 10). For once-through water cooling systems, the 
concentration of concern for environmental effects on freshwater green 
algae and daphnids would be exceeded 99 days per year (Ref. 10).

IV. Technical Summary

    Based on EPA's most recent assessment, the Agency has preliminarily 
determined that DBNPA: (1) Can reasonably be anticipated to cause 
subchronic gastrointestinal effects; and (2) can reasonably be 
anticipated to cause toxicity to freshwater green algae, chronic 
effects on freshwater invertebrates, and chronic effects on oysters, at 
relatively low concentrations. EPA's toxicological evaluation of DBNPA 
indicates that it exhibits acute toxicity only at levels that exceed 
the expected releases and resultant exposures.

V. Administrative Stay

A. Rationale for Decision

    EPA is granting the request for an administrative stay of the 
listing of DBNPA on the EPCRA section 313 list of toxic chemicals. EPA 
proposed to list DBNPA because scientific evidence showed that it 
exhibited chronic human toxicity effects, specifically citing 
respiratory toxicity (59 FR 1807). The Agency affirmed this finding in 
the final rule (59 FR 61452). In the final rule, the Agency responded 
to commenters who argued that the respiratory effects cited were a 
result of an acute toxic reaction to direct exposure to the respiratory 
system from the gavage dosing methodology. At that time the Agency 
stated that ``. . .the dyspnea observed in the 4-week and 13-week rat 
gavage studies cited in the proposed rule may have been due to severe 
irritation of the trachea and lungs from accidental or incidental 
delivery of small amounts of the DBNPA dosing solutions into the 
larynx, pharynx, trachea, and/or lungs during the procedure. However, 
this suggestion of possible cause can be neither refuted nor confirmed 
based upon the available data.'' Since the publication of the final 
rule, the Agency has preliminarily determined that it had incorrectly 
categorized the effects in studies which were reviewed prior to 
promulgation. EPA currently believes that these data serve to confirm 
the acute nature of the respiratory toxicity of DBNPA. EPA's further 
review of DBNPA data also indicates that DBNPA causes gastric toxicity 
and environmental toxicity, and meets the 313(d)(2)(B) and 313(d)(2)(C) 
listing criteria on that basis.
    Although the statutory basis for the determination that DBNPA meets 
the listing criteria of EPCRA section 313(d)(2) would not change, the 
Agency now believes that the listing should be based on effects other 
than that listed in the final rule. EPA recognizes that, although its 
ultimate decision would remain unchanged, interested parties may 
disagree with the Agency's position that the information on subchronic 
gastric effects supports a finding under section 313(d)(2)(B) or its 
position that the information on environmental toxicity supports a 
finding under section 313(d)(2)(C). EPA believes good cause exists to 
issue this Administrative Stay to allow parties time to prepare and 
submit comment and information on these points.

B. Legal Authority

    The Agency believes that this administrative stay is appropriate 
and in the interest of justice, given the fact that EPA incorrectly 
categorized the effects observed in certain data relating to DBNPA 
prior to promulgation of the final rule adding this chemical to the 
EPCRA section 313 list of toxic chemicals. Although the Agency does not 
regard today's stay as a rule, were it to be viewed as a rule, the 
Agency believes that there is good cause for issuing it without prior 
notice and opportunity for comment and for making it immediately 
effective. Under section 313(a), facilities face a current and ongoing 
obligation to collect information about releases, transfers, and waste 
management of DBNPA. Until such time as the issues described in this 
document are resolved, EPA believes that this administrative stay is 
necessary. As stated above, EPA has begun addressing these issues and 
will move quickly toward final resolution of the status of DBNPA under 
EPCRA section 313.
    In addition, this administrative stay is authorized by 5 U.S.C. 
section 705, which provides that an agency may postpone the effective 
date of any action taken by it when justice so requires, pending 
judicial review. Although no petition for review has been formally 
filed as of this date with respect to DBNPA, the Agency believes that 
rather than going through costly and potentially protracted litigation, 
an Administrative Stay coupled with a Federal Register notice and 
opportunity to comment is both consistent with the goal of the TRI 
program to involve the public in the resolution of important issues and 
in the interest of justice.

C. Effective Date of Administrative Stay

    This administrative stay, which applies only to the listing of 
DBNPA on the EPCRA section 313 list of toxic chemicals is effective 
October 27, 1995.
