California Voters Pass Coastal Initiative (Regional)  By a 55% margin, voters approve a statewide proposition establishing the California Coastal Commission, mandating creation of a state coastal conservation plan, limiting coastal development, prohibiting widening coastal Highway 1 into a freeway, and allowing increased public access to the shoreline.

EPA Bans DDT (National)  An EPA regulation bans use of this long-lived pesticide, which builds up to toxic levels as it passes up the food chain, poisoning birds and animals that eat fish from contaminated waters.

Congress Passes Clean Water Act (National)  New law requires secondary sewage treatment; restricts other pollutants in rivers, lakes, and streams.  In 1972, only 30% of U.

Endangered Species Act (National)  Congress approves, and President Nixon signs (on December 28), a new law to strengthen and expand the weaker 1966 endangered species law.

Enforcement Against Smelters' Air Pollution (Regional)  The EPA begins enforcement action against eight ore smelters in Arizona and Nevada which emit a total of two million tons of sulfur dioxide annually.  By the mid-1980s, some of these smelters install pollution controls; others shut down.  By the 1990s, SO2 emissions from these facilities decrease by 94%.


CFCs Shown To Harm Ozone Layer (National)  University of California scientists Mario Molina and Sherwood Rowland publish their finding that chlorofluorocarbons (CFCs) used in spraycans, styrofoam, and in air conditioners and refrigeration equipment, is damaging the earth's stratospheric ozone layer, which protects life from harmful ultraviolet radiation.

EPA Completes Clean Water Permits Effort (Regional)   EPA's completes an intense three- year effort to issue strict new permits for all major wastewater dischargers, such as factories and sewage treatment plants, in Arizona, California, Nevada, and Hawaii.  The permits mandate an estimated 90% reduction in pollutants entering surface waters.
