Background

The Division of Surface Water (DSW) is in the process of conducting a review of Chapters 3745-2 and 3745-33 of the Administrative Code, governing the technical process for converting Ohio water quality standards (WQS) to wasteload allocations that can be used as wastewater permit limits and the administrative and technical requirements for writing and obtaining National Pollutant Discharge Elimination System (NPDES) permits. As part of this review, revisions to rule 3745-1-06 were necessary. The fact sheet below describes the draft changes.
