The plant discharges into the Pacific Ocean via the Santa Monica Bay, which is part of the Southern California Bight. This coastal region supports a rich marine ecosystem, including kelp forests, fish populations, and migratory seabirds. The bay is also a popular recreational area, making proper wastewater treatment critical for water quality and habitat preservation.
