In 1990, permitting regulations were developed by the U.S. Environmental Protection Agency (EPA) under the National Pollutant Discharge Elimination System (NPDES). These regulations control stormwater discharges from industrial facilities with the potential to pollute waters of the United States. Zinc is a regulated pollutant in industrial stormwater discharges, and zinc concentrations in runoff from galvanized roofs is a concern across all industry sectors.

Whatever the nature of your business, and the activities you engage in to run your business, your roof runoff poses a risk of releasing contaminants such as TSS, organics and heavy metals into the watershed. You need to stay in compliance. We get it and we have solutions.
