When a toxic waste site is hit by a hurricane or a flood, the chemicals buried there can wash into people's yards or local water supplies. As extreme weather becomes more frequent, cleanups designed decades ago may no longer be enough to hold back the waste. This bill aims to prevent environmental disasters by ensuring that toxic sites are 'future-proofed.' If this becomes law, it could prevent the massive costs and health crises that occur when a cleanup fails during a natural disaster. Without it, many cleanups remain vulnerable to the changing environment.
