- 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 252:690-3-10 through 3-13 and 3-16.(1) WLAYMS. Equation H-1 is used to calculate WLAYMS.(2) WLASS.
