It would also be helpful if you provided the name, date, and Federal Register citation related to your scientific views. II. Background and Today's Action A. What Are Recommended Water Quality Criteria? Recommended water quality criteria are the concentrations of a chemical in water at or below which aquatic life are protected from acute and chronic adverse effects of the chemical. Section 304(a)(1) of the Clean Water Act requires EPA to develop and publish, and from time to time revise, criteria for water accurately reflecting the latest scientific knowledge. Water quality criteria developed under section 304(a) are based solely on data and scientific judgments. They do not consider economic impacts or the technological feasibility of meeting the criteria in ambient water. Section 304(a) criteria provide guidance to States and Tribes in adopting water quality standards. The criteria also provide a scientific basis for EPA to develop Federally promulgated water quality standards under section 303(c). B. What Is Diazinon and Why Are We Concerned About It? Diazinon is an organophosphorus pesticide used throughout the U.S. to control insects in agricultural areas, [[Page 75557]] households and urban settings. It is mobile and moderately persistent in the environment. Due to its chemical properties and widespread use, diazinon is frequently found in effluents from wastewater treatment plants and in storm water runoff in both urban and agricultural areas. Diazinon is known to be extremely toxic to birds and aquatic life, particularly invertebrates. For these reasons, EPA has developed the following water quality criteria: C. What Are the Draft National Recommended Water Quality Criteria? Freshwater: Aquatic life should not be affected unacceptably if the: One hour average concentration of diazinon does not exceed 0.10 ug/ L more than once every three years on the average (Acute Criterion) and if the four-day average concentration of diazinon does not exceed 0.10 ug/L more than once every three years on the average (chronic criterion). Saltwater: Aquatic life should not be affected unacceptably if the: One-hour average concentration of diazinon does not exceed 0.82 ug/ L more than once every three years on the average (acute criterion) and if the four-day average concentration of diazinon does not exceed 0.40 ug/L more than once every three years on the average (chronic criterion). D. What Specific Questions of Science Does EPA Want Views On? Though the public is welcome to submit scientific views on any component of the diazinon aquatic life criteria document, EPA is specifically interested in scientific views on the following issues of science: [sbull] The derivation of final chronic values (FCVs) as protective of chronic effects to freshwater and saltwater aquatic life using the available acute and chronic data; [sbull] Scientific information or data made available since the literature search was completed in 1997. For example, information regarding the sub-lethal effects of diazinon (e.g., olfactory or predator-prey response). E. Where Can I Find More Information on EPA's Revised Process for Developing New or Revised Draft Criteria? The Agency published detailed information about its revised process for developing and revising criteria in the Federal Register on December 10, 1998 (63 FR 68354) and in the EPA document entitled, National Recommended Water Quality--Correction (EPA 822-Z-99-001, April 1999). The purpose of the revised process is to provide expanded opportunities for public input, and to make the criteria development process more efficient. Also, EPA notified the public of its intent to develop aquatic life criteria for diazinon in the Federal Register on October 29, 1999 (64 FR 58409). At that time, EPA solicited any pertinent data or scientific views that would be useful in developing the draft aquatic life criteria for diazinon. Dated: December 23, 2003. Geoffrey H. Grubbs, Director, Office of Science and Technology. [FR Doc. 03-32210 Filed 12-30-03; 8:45 am] BILLING CODE 6560-50-P
