Each limit is one EPA's ICIS-NPDES file holds on the permit's current version with a begin date after today, enforceable and numeric, either on a parameter the outfall was never limited on (new) or lower than the limit in force (tighter). Today's median is the plant's own reported values for the same outfall, statistic and unit between Oct 1, 2025 and Sep 30, 2026, with how many; none is shown where most were below a detection limit. Read the permit before relying on a value.
