The Environmental Protection Agency (EPA) is proposing to establish a federal Clean Water Act (CWA) selenium water quality criterion applicable to California that protects aquatic life and aquatic-dependent wildlife in the fresh waters of California. In 2016, the EPA published a revised recommended aquatic life selenium criterion for freshwater based on the latest scientific knowledge. The EPA is proposing to amend the California Toxics Rule to include a revised statewide chronic selenium water quality criterion for California fresh waters to protect aquatic life and aquatic-dependent wildlife which builds upon the science in the EPA's 2016 Final Aquatic Life Ambient Water Quality Criteria for Selenium--Freshwater.
The agency’s own summary, as published.
