Development of permit limitations for the implementation of numerical

criteria for toxic substances to protect the Fish and Wildlife Propagation beneficial use [REVOKED] MALTOX and DMLTOX are calculated from LTATOX. MALTOX is compared with all applicable criterion MALs. The most stringent MAL and associated DML is used in the permit. (1) MALTOX. MALTOX is calculated using a 95% probability basis according to Equation F- 10. (2) DMLTOX. DMLTOX is calculated using a 99% probability basis according to Equation F- 11.
