Current through Register Vol. 48, No. 38, September 20, 2024
The Agency must consider the following practices to determine whether an operator is controlling and treating waters containing elevated levels of total dissolved solids, chloride, or sulfate discharged from the site:
a) Regulating discharges when other control methods are insufficient and chemical treatment is economically unfeasible, including:
1) Regulating the flow
of discharges high in total dissolved solids according to fluctuating or
intermittent stream flows so that the total dissolved solids concentration
remains within established water quality standards; or
2) Regulating the flow or fluctuation of
receiving streams by timely discharge of water from existing impoundments that
have suitable discharge control structures.
b) Rerouting over economically feasible distances, involving collecting discharges and conveying them to more suitable discharge points, such as large holding ponds located adjacent to more suitable receiving streams where dilution or water quality is better.
