A federal court this week restricted the use of 75 pesticides in eight Bay Area counties and ordered the Environmental Protection Agency to study the impacts the chemicals have on wildlife.

The injunction, issued Monday in U.S. District Court in San Francisco, was an effort to protect 11 endangered snakes, insects, birds, fish, mammals, crustaceans and amphibians that live in areas where spraying occurs.

“All of these species were chosen because there is evidence of potential harm,” said Jeff Miller, a conservation advocate for the Center for Biological Diversity, which sued the EPA in 2007. “These pesticide use restrictions will protect some of the Bay Area’s most vulnerable wildlife.”

The order, part of a settlement agreement, prevents registered pesticide applicators, including municipalities, farmers and wineries, from using the 75 pesticides for five years in areas where the listed species reside.

It does not restrict individuals from using the pesticides on their gardens or around their homes. Instead, it requires the EPA to mandate that warnings be placed on all products that contain the chemicals advising people that the pesticide can be harmful to wildlife.

EPA administrators in San Francisco referred inquiries Wednesday to their Washington office, where officials could not be reached for comment.

Miller said the lawsuit was filed because EPA officials consistently ignored their obligation under the Endangered Species Act to consult with the U.S. Fish and Wildlife Service to determine whether pesticides being considered for registration harm listed species or their habitat.
