Any permit effluent limitation, standard, or prohibition for a metal must be expressed in terms of "total recoverable metal" as defined in 40 C.F.R. Part 136, adopted by reference in 18 AAC 83.010, unless

(1) an applicable effluent standard or limitation has been promulgated under 33 U.S.C. 1251 - 1387 (Clean Water Act) and specifies the limitation for the metal in the dissolved, valent, or total form;

(2) in establishing permit limitations on a case-by-case basis under 40 C.F.R. 125.3, it is necessary to express the limitation on the metal in the dissolved, valent, or total form to carry out the provisions of 33 U.S.C. 1251 - 1387 (Clean Water Act); or

(3) all approved analytical methods for the metal inherently measure only its dissolved form, such as hexavalent chromium.
