Permit limits are developed using technology-based and water quality-based methods. Several industrial categories are subject to technology-based effluent limits, which are developed using federal effluent guidelines. Water quality-based effluent limits are developed based on the South Dakota’s Surface Water Quality Standards.
Industrial Categories subject to effluent guidelines can be found on EPA’s website: Industrial Categories
Additional effluent guideline information can be found on EPA’s website: Effluent Guidelines Information
