What organization was established to help protect California's coastline from pollution?

The California Coastal Commission is recognized as a key organization dedicated to protecting California's coastline, primarily from pollution as well as development that could harm coastal resources. Established in 1976, the Commission's mission includes the protection and enhancement of the coastal zone's natural environment, ensuring public access, and balancing coastal development pressures.

This organization plays a vital role in regulating land use along the coast, reviewing coastal development permits, and promoting conservation efforts. Its focus on pollution prevention encompasses a broad range of concerns, including water quality and the ecological health of coastal habitats, thus directly aligning with the need to protect California's coastal areas from environmental harm.

In contrast, other options like the California Environmental Protection Agency focus more broadly on environmental issues across the entire state, while the California Water Resources Board pertains specifically to water management and resources. The Pacific Ocean Protection Agency mentioned does not formally exist, making it not a viable entity for this question's context.
