Fecal Coliform Newport Bay TMDL

Fecal Coliform Newport Bay TMDL

Amendment to the Water Quality Control Plan for the Santa Ana River Basin to Revise the Schedule for Attaining the Fecal Coliform Total Maximum Daily Loads for the Shellfish Harvesting Beneficial Use in Newport Bay.

A basin plan amendment was developed and adopted by the Santa Ana Water Board at the June 3 public hearing to extend the deadline for attainment of the water quality objectives (WQOs) for the shellfish beneficial use (SHEL) in Newport Bay, from December 31, 2022, to December 31, 2030. The purpose of the extension is to allow additional time to complete studies that are currently in progress to determine whether there is a correlation between fecal indicator bacteria in water and fecal indicator bacteria and pathogens in shellfish tissue. A dry season study of bacteria in the water column and bacteria in shellfish was completed by the Southern California Coastal Water Research Project. The study found no correlation between the SHEL WQOs in water and bacteria and pathogen levels in Pacific oysters in Newport Bay. A similar study has been planned for the wet season and is slated to begin in the fall of 2022.
