Metal Fabricator Industrial Stormwater General Permit Support, Seattle, WA

A metal fabricator and electrical supplier was sued under the Clean Water Act for elevated concentrations in stormwater zinc just weeks before of a Level 3 Corrective Action deadline. Aspect quickly determined roofing was the primary source and negotiated installation of a roof downspout filter—meeting the deadline and greatly aiding settlement. After settlement, we assisted the client in coating the roof to avoid ongoing maintenance costs. The site now routinely meets all benchmarks.
