 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Notice.
 SUMMARY: This notice announces the availability of EPA's draft ecological risk assessment for the registration review of inorganic nitrates - nitrites, carbon and carbon dioxide, and gas cartridge uses of sulfur, and opens a public comment period on this document. Comments and input may address, among other things, the Agency's risk assessment methodologies and assumptions, as applied to this draft risk assessment. Interested parties may also provide suggestions for mitigation of the risk identified in the draft ecological risk assessment. As part of the registration review process, the Agency has completed a comprehensive draft ecological risk assessment, including an endangered species assessment that identifies those species for which exposure and effects may occur for all inorganic nitrates-nitrites, carbon and carbon dioxide uses, as well as gas cartridge uses of sulfur. The risk assessment includes a species specific analysis and effects determination on 3 of 11 species found in the San Francisco Bay area that are listed as endangered or threatened under the Endangered Species Act (ESA). Concurrent with this public comment opportunity, EPA is initiating informal consultation with the U.S. Fish and Wildlife Service. After reviewing comments received during this public comment period, EPA will issue a revised risk assessment, explain any changes to the draft risk assessment, and respond to comments. The Agency may request further public input on risk mitigation before developing a proposed registration review decision for inorganic nitrates - nitrites, carbon and carbon dioxide, and sulfur. After a revised risk assessment is completed, EPA will also initiate further consultation, as needed, when appropriate, with the U.S. Fish and Wildlife Service regarding potential risks to federally listed threatened or endangered species and their designated critical habitat.

EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of any group, including minority and/or low income populations, 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 or disproportionately high and adverse human health impacts or environmental effects from exposure to the pesticide(s) discussed in this document, compared to the general population. II. Authority EPA is conducting its registration review of inorganic nitrates - nitrites, carbon and carbon dioxide, and sulfur pursuant to section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Procedural Regulations for Registration Review at 40 CFR part 155, subpart C. Section 3(g) of FIFRA provides, among other things, that the registrations of pesticides are to be reviewed every 15 years. Under FIFRA, a pesticide product may be registered or remain registered only if it meets the statutory standard for registration given in FIFRA section 3(c)(5). When used in accordance with widespread and commonly recognized practice, the pesticide product must perform its intended function without unreasonable adverse effects on the environment; that is, without any unreasonable risk to man or the environment, or a human dietary risk from residues that result from the use of a pesticide in or on food.

 III. Registration Reviews A. What Action is the Agency Taking? As directed by FIFRA section 3(g), EPA is reviewing the pesticide registrations for inorganic nitrates - nitrites, carbon and carbon dioxide, and sulfur to ensure they continue to satisfy the FIFRA standard for registration—that is, that inorganic nitrates - nitrites, carbon and carbon dioxide, and sulfur can still be used without unreasonable adverse effects on human health or the environment. Inorganic nitrates - nitrites, carbon and carbon dioxide are active ingredients and are mixed in some cases with sulfur, to create fumigant gas cartridges which release toxic fumes after ignition. These gas producing cartridges are placed in animal burrows to control small mammal pests. EPA has completed a comprehensive draft ecological risk assessment, including an endangered species assessment, for all inorganic nitrate - nitrite, carbon and carbon dioxide uses, as well as gas cartridge 
                    ( print page 29536)
                    uses of sulfur. All other uses of sulfur will be included in the upcoming ecological risk assessment for the registration review of sulfur, docket EPA-HQ-OPP-2008-0176. The risk assessment includes a species specific analysis and effects determination of the cartridges on 3 of 11 species found in the San Francisco Bay area that are listed as endangered or threatened under the Endangered Species Act (ESA). These species specific effects determinations were conducted in response to litigation brought against EPA by the Center for Biological Diversity in the United States District Court for the Northern District of California (Civ. No. 07-2794-JSC) where sodium nitrate and potassium nitrate were alleged to be of concern. Pursuant to 40 CFR 155.53(c), EPA is providing an opportunity, through this notice of availability, for interested parties to provide comments and input concerning the Agency’s draft ecological risk assessment for inorganic nitrates - nitrites, carbon and carbon dioxide, and gas cartridge uses of sulfur. Such comments and input could address, among other things, the Agency’s risk assessment methodologies and assumptions, as applied to this draft risk assessment. Interested parties may also provide suggestions for mitigation of the risk identified in the draft ecological risk assessment. Concurrent with this public comment opportunity, EPA is initiating informal consultation with the U.S. Fish and Wildlife Service for purposes of validating the list of potentially affected species, to identify the geographic areas in which each species may reside, and to assist EPA in determining how best to assemble information on the baseline status of each species. The ESA regulations provide for two types of consultation; formal and informal. Informal consultation is an optional process that includes discussions, correspondence, etc. between the Services and a Federal agency or a designated non-Federal representative (NFR) to determine whether a Federal action is likely to have an adverse effect on listed species or critical habitat. During informal consultation the Services may suggest modifications to the action that a Federal agency, permit applicant or non-Federal representative could implement to avoid likely adverse effects to listed species or critical habitat. If adverse effects are likely and those effects cannot be addressed through informal consultation, then formal consultation generally occurs. The Agency will consider all comments received during the public comment period and make changes, as appropriate, to the draft ecological risk assessment. EPA will then issue a revised risk assessment, explain any changes to the draft risk assessment, and respond to comments. EPA will also, at that time, initiate further consultation, as needed, when appropriate, with the U.S. Fish and Wildlife Service regarding potential risks to federally listed threatened or endangered species and their designated critical habitat. In the 
                    **Federal Register**
                     notice announcing the availability of the revised risk assessment, if the revised risk assessment indicates risks of concern, the Agency may provide an additional comment period for the public to submit suggestions for mitigating the risk identified in the revised risk assessment before developing proposed registration review decisions on inorganic nitrates - nitrites, carbon and carbon dioxide, and sulfur. B. Docket Content As described in detail in the Inorganic Nitrate-Nitrite Summary Document (see docket ID number EPA-HQ-OPP-2007-1118), Carbon and Carbon Dioxide Summary Document (see docket ID number EPA-HQ-OPP-2007-0705) the Agency believes that the human health risk assessments completed prior to registration review are adequate, and there are no human health risks that exceed the Agency’s level of concern. Thus, no additional human health data are expected to be needed for the registration review of inorganic nitrates - nitrites, carbon and carbon dioxide. In the Sulfur Summary Document (see docket ID number EPA-HQ-OPP-2008-0176) the Agency stated that revised occupational and residential exposure human health assessments for sulfur should be conducted in registration review. These human health assessments are still anticipated for all uses of sulfur, including the cartridge use, and will be included in the upcoming registration review risk assessment. 1.
