Section 301.267 Conversion Factor

“Conversion Factor” means the fraction of the total metal found as dissolved in the

toxicity tests used to derive the water quality standards of Part 302. The conversion

factors are used to convert total metals water quality standards to dissolved standards.

Section 301.313 Metals Translator

“Metals Translator” means the fraction of total metal that is dissolved in the effluent or

downstream water. The metals translator calculates a total metal permit limit from a

dissolved metal water quality standard. In the absence of site-specific data for the

effluent or receiving water, the metals translator is the reciprocal of the conversion factor.

Section 301.413 Total Metal

NOTICE OF PROPOSED AMENDMENTS

“Total Metal” means the dissolved fraction of metal in a solution plus the suspended
