Calbag Metals Co., a nonferrous scrap metal recycling facility in Portland, Ore. had difficulty consistently meeting its Oregon 1200Z General Industrial Stormwater Discharge Permit benchmarks for lead, copper and zinc. Over a two-year period, particulate metal had been building up gradually on the 2.5 asphalt-paved acres surrounding the facility. After trying several ineffective methods to address the problem, the company turned to a best management practice (BMP) involving two, above ground CatchBasin StormFilters™ filled with permeable media to solve the problem.
