The Environmental Protection Agency (EPA) wants the public to weigh in on a $630 million plan to fix the region’s cross border pollution problems.

Federal officials have completed a draft environmental impact review on a project that would treat sewage in the waters along the U.S.-Mexico border near San Diego and they are looking for public comment.

The agency is recommending a sweeping plan to bolster the capture and treatment of sewage tainted flows on both sides of the international border.
