(a) Protection of the best usage of fishing shall include standards and guidance values for protection of the health of wildlife consumers of aquatic life and water. Such values are referred to as Wildlife values.

(b) Standards and guidance values to protect wildlife shall be derived using levels of chemicals known to be toxic to wildlife in conjunction with a bioaccumulation factor and wildlife consumption rates of aquatic life and water.

(c) Where the available data are deemed insufficient for deriving a value on the basis of subdivision (b) of this section, a value may be based on correlation to a chemical for which a standard or guidance value has been established pursuant to that subdivision. Values based on chemical correlation may be established where similar toxic effects are anticipated because of similarity of functional groups or metabolic or toxicologic pathways.
