The Metals Translator
Guidance for Calculating a Total Recoverable Permit Limit from a Dissolved Criterion
EPA-823-B-96-007
The metals translator is a tool for environmental scientists and permit writers to use in calculating the amount of a metal that may be discharged from a facility to a surface water body based on how the metal is distributed (partitioned) between water and sediments in the receiving stream. This technical guidance explains how the translator is used in setting limits on the amount of a metal that can by discharged in both simple and complex situations involving single dischargers or multiple dischargers, and still protect aquatic life. The guidance discusses how these translators can be developed for specific water bodies to reflect various naturally occurring circumstances. It also includes information on clean sampling and analytical procedures that the user may elect to follow.
