Protecting the Bay From Trump's EPA

The Trump administration has reached a new low in its assault on clean water.  Trump’s Environmental Protection Agency is claiming that San Francisco Bay water isn’t water. The agency recently decided that the South Bay salt ponds are land and don’t need Clean Water Act protection. 

This bizarre decision is dangerous for San Francisco Bay. 

Corporations created the South Bay salt ponds by building levees in the Bay before the Clean Water Act was enacted. In an abrupt reversal of its own 2016 draft opinion, EPA says the timing of those levees now means that the ponds are land instead of water.  

It’s a thinly veiled scheme to allow Cargill, the multinational corporation that owns the area, to pave over the ponds without worrying about meeting Clean Water Act safeguards. In reality, if the levees are removed, Bay waters will flood the area again and eventually return the ponds to their former wetland state. 

That’s why Baykeeper is suing the Trump administration in federal court, fighting to overturn this decision. 

The areas at the heart of the battle are the brightly colored salt ponds you can see from the window of a plane flying over the Bay Area. Cargill’s goal is to fill two square miles of these salt ponds along the Redwood City shoreline so that developers can build offices, homes and retail spaces.  

Baykeeper is joining with Save the Bay, Citizens Committee to Complete the Refuge and Committee for Green Foothills to defend this part of the Bay’s shoreline. And our partners are also working to prevent Cargill from getting the state and local permits needed before construction can begin.    

The salt ponds have been used for industrial-scale salt harvesting for over 100 years. But for centuries before, the ponds were salt marshes where the native people of the Bay Area harvested small amounts of salt for everyday use. 

Erecting buildings on these former wetlands is a bad idea. In 50 to 80 years, sea level rise will put those buildings partly underwater. And the area is currently home to thousands of shorebirds and local wildlife that would be displaced if the ponds were paved. 

Restoring the ponds to wetlands will help protect the Redwood City shoreline against sea level rise. Restored wetlands will also protect the nearby Silicon Valley tech campuses and infrastructure like sewage treatment plants that, if flooded, could badly pollute San Francisco Bay. Wetlands additionally provide food for seasonal and year-round birds, plus habitat for endangered species. 

And there are even more reasons to overturn the Trump administration’s giveaway to Cargill.  

Because the Trump decision removes the need for a federal development permit, it increases the ponds’ market value. That allows Cargill to profit even more by destroying the Bay. A higher market value also makes it harder, and more expensive, for taxpayers to save the Redwood City ponds through a public purchase.     

And if the Trump decision stands, it will be easier for Cargill, and any other corporation, to pave other parts of the Bay, including salt ponds on the Newark shoreline.
