The higher of 250 mg/L or the limiting LTA is used to develop chloride and sulfate permit limitations. The higher of 700 mg/L or the limiting LTA is used to develop TDS permit limitations.

1. (1) MAL. MAL_CL, MAL_SO4 and MAL_TDS are each determined on a 95% probability basis according to Equations N-8, N-9, and N-10, respectively.
2. (2) DMLs. DML_CL, DML_SO4 and DML_TDS are also determined on a 95% probability basis according to Equations N-11, N-12, and N-13, respectively.
