- a local limit exists for each pollutant discharged and the user was in compliance with each limit directly prior to, and during, the pass through or interference; or
- no local limit exists, but the discharge did not change substantially in nature or constituents from the user’s prior discharge when the City was regularly in compliance with its NPDES permit, and in the case of interference, the City was in compliance with applicable sludge use or disposal requirements.
