Yes—if your project involves concrete, mortar, stucco, or grout, you are typically required to have a designated washout area. In New York City, this is reinforced by NYC Local Law 70, which requires proper containment and disposal of concrete washout materials.
Local and state regulations—including NJDEP and EPA stormwater rules—strictly prohibit dumping into streets, storm drains, or catch basins. A professional washout system - helps protect your project from violations and keeps inspections running smoothly.
