Alkylbenzene Sulfonates Risk Assessment and Preliminary Risk 
Reduction Options; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's risk 
assessment, preliminary risk reduction options, and related documents 
for the pesticide alkylbenzene sulfonates which

[[Page 20091]]

encompasses sodium dodecylbenzene sulfonate; dodecylbenzene sulfonic 
acid; and benzenesulfonic acid, C10-C16 alkyl derivatives, and opens a 
public comment period on these documents. The public also is encouraged 
to suggest risk management ideas or proposals to address the risks 
identified. EPA is developing a Reregistration Eligibility Decision 
(RED) for alkylbenzene sulfonates through a modified, 4-Phase public 
participation process that the Agency uses to involve the public in 
developing pesticide reregistration and tolerance reassessment 
decisions. This is Phase 3 of the 4-Phase Process. Through these 
programs, EPA is ensuring that all pesticides meet current health and 
safety standards.

II. Background

A. What Action is the Agency Taking?

    EPA is releasing for public comment its human health and 
environmental fate and effects risk assessment, preliminary risk 
reduction options, and related documents for alkylbenzene sulfonates 
(encompassing sodium dodecylbenzene sulfonate; dodecylbenzene sulfonic 
acid; and benzenesulfonic acid, C10-C16 alkyl derivatives), and 
encouraging the public to suggest risk management ideas or proposals. 
The alkylbenzene sulfonates are both active and inert ingredients in 
pesticide products. As active ingredients, they are currently found in 
end-use products as a disinfectant, food-contact sanitizer, 
bacteriocide/bacteriostat, microbiocide/microbiostat, fungicide/
fungistat, and virucide. As inert ingredients, they are found in end-
use products, many of which are used in residential settings, and 
outdoors in agricultural settings. EPA developed the risk assessment 
and preliminary risk reduction options for alkylbenzene sulfonates 
through a modified version of its public process for making pesticide 
reregistration eligibility and tolerance reassessment decisions. 
Through these programs, EPA is ensuring that pesticides meet current 
standards under the Federal Insecticide, Fungicide, and Rodenticide Act 
(FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as 
amended by the Food Quality Protection Act of 1996 (FQPA).
    The alkylbenzene sulfonates are both active and inert ingredients 
in pesticide products. As active ingredients, they are currently in 23 
registered end-use products as a disinfectant, food-contact sanitizer, 
bacteriocide/bacteriostat, microbiocide/microbiostat, fungicide/
fungistat, and virucide. Alkylbenzene sulfonates are in cleaners and 
sanitizers that are designated for use in agricultural, food handling 
and commercial/institutional/industrial settings. Examples of 
registered uses for alkylbenzene sulfonates include, but are not 
limited to: Application to indoor hard surfaces e.g., urinals, shower 
stalls, toilet bowls, etc., food dispensing equipment (e.g., pre-mix 
and post-mix vending machines), food contact surfaces (glasses, dishes, 
silverware, countertops, etc.), agricultural tools, and fruits and 
vegetables (post-harvest). As active ingredients, there are no 
residential or outdoor uses currently registered. As inert ingredients, 
there are approximately 350 registered end-use products containing 
these chemicals. Many of these products are used in residential 
settings, and outdoors in agricultural settings. The Agency's risk 
assessment identified dietary, residential and occupational risks of 
concern for some exposure scenarios. Because limited information is 
available for some exposure scenarios conservative assumptions were 
sometimes used in the risk assessment. The Agency is interested in 
receiving any information that could assist in refining the risk 
assessment.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessment for alkylbenzene sulfonates. Such comments and input could 
address, for example, the availability of additional data to further 
refine the risk assessments, such as ecological data to fill data gaps 
for aquatic toxicity studies for freshwater fish and invertebrates, or 
could address the Agency's risk assessment methodologies and 
assumptions as applied to this specific pesticide. Through this notice, 
EPA is also releasing for public comment its preliminary risk reduction 
options for alkylbenzene sulfonates, and is providing an opportunity 
for interested parties to provide risk management proposals or 
otherwise comment on risk management.
    EPA seeks to achieve environmental justice, the fair treatment and 
meaningful involvement of all people, regardless of race, color, 
national origin, or income, in the development, implementation, and 
enforcement of environmental laws, regulations, and policies. To help 
address potential environmental justice issues, the Agency seeks 
information on any groups or segments of the population who, as a 
result of their location, cultural practices, or other factors, may 
have atypical, unusually high exposure to alkylbenzene sulfonates, 
compared to the general population.
    EPA is applying the principles of public participation to all 
pesticides undergoing reregistration and tolerance reassessment. The 
Agency's Pesticide Tolerance Reassessment and Reregistration; Public 
Participation Process, published in the Federal Register on May 14, 
2004, (69 FR 26819) (FRL-7357-9) explains that in conducting these 
programs, the Agency is tailoring its public participation process to 
be commensurate with the level of risk, extent of use, complexity of 
the issues, and degree of public concern associated with each 
pesticide. For alkylbenzene sulfonates, a modified, 4-Phase process 
with one comment period and ample opportunity for public consultation 
seems appropriate in view of its refined risk assessment, few complex 
issues, and/or other factors. However, if as a result of comments 
received during this comment period EPA finds that additional issues 
warranting further discussion are raised, the Agency may lengthen the 
process and include a second comment period, as needed.
    All comments should be submitted using the methods in ADDRESSES, 
and must be received by EPA on or before the closing date. Comments 
will become part of the Agency Docket for alkylbenzene sulfonates. 
Comments received after the close of the comment period will be marked 
``late.'' EPA is not required to consider these late comments.

B. What is the Agency's Authority for Taking this Action?

    Section 4(g)(2) of FIFRA as amended directs that, after submission 
of all data concerning a pesticide active ingredient, ``the 
Administrator shall determine whether pesticides containing such active 
ingredient are eligible for reregistration'' before calling in product 
specific data on individual end-use products and either reregistering 
products or taking other ``appropriate regulatory action.''
    Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to 
review tolerances and exemptions for pesticide residues in effect as of 
August 2, 1996, to determine whether the tolerance or exemption meets 
the requirements of section 408(b)(2) or (c)(2) of FFDCA. This review 
is to be completed by August 3, 2006.
