SECTION 785:46-7-1. Applicability and scope
Latest version.
- (a) General. Rules in this Subchapter prescribe the method for determining regulatory flow and to determine whether there is a reasonable potential to exceed the criteria, all in order to implement numerical criteria to protect human health for consumption of fish flesh and/or water.(b) Applicable public and private water supply criteria. Applicable criteria for waters designated Public and Private Water Supplies are found in OAC 785:45-5-10(1) , OAC 785:45-5-10(6) and OAC 785:45 Appendix G.(c) Applicable fish consumption criteria. Applicable criteria for waters designated Warm Water Aquatic Community and/or Cool Water Aquatic Community and/or Trout Fisheries are found in 785:45-5-20 and OAC 785:45 Appendix G.(d) Appropriate criterion. If several criteria apply to human health implementation, the most stringent is used for implementation purposes.(e) Applicable receiving waters. The human health criteria apply in receiving waters designated as Public and Private Water Supplies and certain designated sub-categories of Fish and Wildlife Propagation. Some streams in Appendix A of OAC 785:45 are designated Habitat Limited Aquatic Communities, and are not designated for the Public and Private Water Supply beneficial use. Therefore, human health criteria do not apply to these streams. For implementation purposes these streams are considered conduits to the downstream water body. Human health criteria must be implemented on the first downstream water body to which they apply.
