Wasteload allocations for the implementation of mineral constituent criteria

to protect the Agriculture beneficial use If either Cd(YMS) or Cd(SS) exceeds its respective criterion, a water quality-based permit limit is required for that mineral constituent. WLAYMS and WLASS are calculated for each mineral constituent exhibiting reasonable potential. Background levels used in calculating agriculture- based WLAs are described in OAC 252:606-6-10 through 6-13 and 6-16. (1) WLAYMS. Equation N-1 is used to calculate WLAYMS. (2) WLASS. Equation N-2 is used to calculate WLASS.
