A. What Action is the Agency Taking?
EPA is releasing for public comment its human health and environmental fate and effects risk assessments and related documents for chlorine dioxide and encouraging the public to suggest risk management ideas or proposals. Chlorine dioxide, sodium chlorite and sodium chlorate are active ingredients in numerous products used in the control of bacteria, fungi and algal slimes. In addition, it is used to disinfect drinking water and as a microbiocide in cooling tower waters. EPA developed the risk assessments for chlorine dioxide 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).
At this time, products containing chlorine dioxide and sodium chlorite are intended for agricultural, commercial, industrial, medical and residential use. The agricultural premises and equipment uses include the disinfection of hard surfaces and equipment (such as hatching facilities Start Printed Page 24685and mushroom houses) and water systems (such as chiller water and humidification water in poultry houses). Commercial, industrial, and medical uses include disinfection of hard surfaces (e.g., floors, walls, and laboratory equipment), human drinking and industrial cooling water systems, pulp/paper mills, and food rinses. Residential uses include disinfection of swimming pools, hard surfaces (e.g., floors, bathrooms), heating ventilating and air-conditioning systems, and pool and spa water circulation system treatments. In addition, there is a continuous release gas product (sachet) for the home to control odors.
The Agency's risk assessments for chlorine dioxide 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 chlorine dioxide. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, or could address the Agency's risk assessment methodologies and assumptions as applied to this specific pesticide. Through this notice, EPA is providing an opportunity for interested parties to provide risk management proposals.
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 chlorine dioxide 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 of 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 chlorine dioxide, a modified, 4-Phase process with one comment period and ample opportunity for public consultation seems appropriate in view of its refined risk assessments, 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 chlorine dioxide. 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.Start List of Subjects
