| Description: |
This measure tracks the number of documented pass through and interference events that were caused by the introduction of pollutants by regulated industrial users (IUs) into the City's wastewater treatment plants that are a part of the City's approved Pretreatment Program. The Pretreatment Program objectives described as benefits above are met by implementing and enforcing the AWU's approved Pretreatment Program on its industrial users (IUs) through plan reviews, inspections, permitting, surveillance, sampling and monitoring and enforcement when applicable. Pass through and interference are federally defined terms that are a result of pollutants discharged by IUs to the publicly owned treatment works (POTW) at levels that would pass through the wastewater treatment plant or upset the plant such that a permit violation would occur. A lower number is better as indicated by 0 being the goal. |
