All adopted classifications must conform to the standards and rules contained within R.61-68, Water Classifications and Standards, or site-specific standards listed within this regulation. Unless noted, site-specific standards apply only to the water named and not to tributary or downstream waters. B. Tributaries to Classified Waters. Where surface waters are not classified by name (unlisted) in this regulation, the use classification and numeric standards of the class of the stream to which they are tributary apply, disregarding any site-specific numeric standards for the named waterbody. In tidal areas, where an unlisted tributary may affect or flows between two differently classified waterbodies, regardless of whether the location is upstream or downstream, the more stringent numeric standards of the classified waters apply to the unlisted tributary, disregarding any site-specific numeric standards for those waterbodies. C. Status of Classifications and Reviews. The classification for all bodies of water contained herein supersedes all previous classifications. The classifications listed within this regulation shall be open to review to ensure that the classification use is still valid and justified. D. No Discharge Zone Designations. The Department may determine in accordance with Section 312 of the Clean Water Act that for some waterbodies (or portions of waterbodies), the designation of No Discharge Zone (NDZ) for Marine Sanitation Devices (MSDs) shall be enacted with application of the existing classified standards of the waterbody. The designation is listed in this regulation as an NDZ following the waterbody name. E. Class Abbreviations. F. Notations for Site-Specific Standards and Previous Class. An “sp” by the Class means the Department has established site-specific standards for certain parameters for that waterbody. The site-specific standards are listed in parentheses after the waterbody description. For convenience, on both ONRW and ORW waterbodies, the previous classification for the specific waterbody is given in parentheses after the Class listing. G. County Abbreviations. H.
