Welcome to the homepage for the San Luis Obispo COASTKEEPER® at EPI - Environment in the Public Interest

Environment in the Public Interest (EPI) is a 501(c)(3) organization providing educational, scientific and technical support services with a primary mission to advocate the public interest in preserving habitat and biodiversity.

EPI, (doing business in San Luis Obispo County as the San Luis Obispo COASTKEEPER), uses a science-based approach to advocate public trust resource protection before government agencies; provide environmental analysis and expertise; and offer educational and civic engagement opportunities to the public regarding how to participate in agency decisions and permit compliance issues with a goal of protecting the extraordinary wildlands, wildlife, and waters of the California Central Coast region.

EPI was incorporated specifically to be a force for environmental protection and we deploy our efforts in 3 program areas:

• San Luis Obispo Coastkeeper – our water quality initiative.
• Life on the Edge – our biodiversity initiative.
• Government and People – our civic engagement initiative.


The San Luis Obispo COASTKEEPER is remodeling this website.
