Protecting the Environment

In partnership with our customers, Sausalito-Marin City Sanitary District has developed plans and programs to safeguard our beautiful local environment.

The District uses advanced technology to prevent spills and leaks. We encourage our customers to do their part by properly disposing of household hazardous waste, and avoid flushing it down the drain or toilet.

Regulatory Matters -

The District operates under a permit issued by the San Francisco Regional Water Quality Control Board. The permit is for a limited period and is subject to review, modification and renewal.

The permit contains conditions on the type and amount of pollutants that can be discharged into San Francisco Bay. This is in accord with the federal Clean Water Act of 1972 that seeks to restore and maintain the chemical, physical and biological integrity of the Nation's waters.

The District strives to fully comply with the permit regulations to protect public health and the environment and to avoid penalties.

Currently, the District and other local agencies are operating under an Administrative Compliance Order from the US Environmental Protection Agency (USEPA) to improve our systems.
