EPA Says California Is Failing To Protect Its Water Systems

The EPA has raised concerns about water pollution in California, particularly in San Francisco, due to human waste from the homeless population. EPA Administrator Andrew Wheeler has urged California to comply with federal clean water laws, threatening action if not addressed. San Francisco officials, including Mayor London Breed, deny the claims, attributing them to political retaliation by the Trump administration. President Trump has also announced revoking California's emission standards, escalating tensions between the state and federal government.

What was the deadline given by Wheeler for California to respond to the concerns outlined in the letter?
