note
Action Date: March 4, 2026; Effective Date: April 1, 2026; Expiration Date: March 31, 2031. No public notice number or comment period end date found in the document. Permit action is likely 'new' given application number OH0085863 (no prior permit cited), but could be a renewal — document does not explicitly state. Outfall 1PX00010588 is a sludge monitoring station (not a discharge outfall). Sampling station 1PX00010001 coordinates: N 39.454167, W -83.932778.

⚠ Gaps in the record
  • permit_action inferred as 'new' — document does not explicitly state renewal or new; application number OH0085863 suggests a new facility
  • No public notice number or comment period end date present in the document
  • stream_network only partially stated: unnamed tributary of Todd Fork — no further downstream chain provided
