The National Association of Homebuilders had sought to invalidate the rule, claiming that only the federal government can regulate these activities. Cook says he would like to see the San Joaquin rule become a national model.

Gordon Nipp with the Bakersfield chapter of the Sierra Club sees no reason homebuilders should get a "free pass."

"The Indirect Source Rule only offsets about half of the air pollution associated with these projects. And of course, when new projects go in, our air gets dirtier. They really ought to be doing more than the Indirect Source Rule requires them to do."

Nipp credits some developers who are doing more than what's required. For example, he says developers such as Castle and Cook have signed agreements with the air district to offset all of the air pollution associated with their projects.
