Updated January 2026
The Clean Water Act continues to prohibit the discharge of pollutants—including concrete washout—into waterways and storm systems. What’s changed in 2026 isn’t the law, but the level of enforcement. Agencies like the Environmental Protection Agency, along with state and local jurisdictions, are applying stricter oversight, aided by digital reporting, site inspections, and increased compliance requirements tied to stormwater permits. Civil penalties can reach $10,000 per day per violation—and enforcement is no longer rare.
At Outpak Washout, we’re hearing it every day: projects requiring washout systems in their specs, or contractors facing citations after an unexpected inspection. Compliance is no longer optional—it’s a standard part of doing business.
We get it. These challenges are real, and that’s exactly why Outpak products are built the way they are—by contractors, for contractors.
