We, the Navajo Nation Environmental Protection Agency, envision a highly technical, competent, sovereign environmental center built upon partnerships, enforcement, restoration, local outreach, and sustainable financial resources.

With respect to Diné values, protect, preserve, and enhance, our Navajo Environment for present and future generations by developing laws, implementing and enforcing strong environmental laws; and to foster public awareness and cooperation through education.
