California Attorney General Xavier Becerra yesterday joined a multistate comment letter objecting to the U.S. Army Corps of Engineers’ (Army Corps) directive to weaken states’ oversight of projects impacting water quality. The Army Corps’ directive would drastically shorten timeframes for state water quality certifications under Section 401 of the Clean Water Act (CWA). This abbreviated timeframe would prevent states from adequately assessing the water quality impacts of proposed federal projects to ensure states’ water resources are protected.
