In this video, we welcome Molly Alar, senior consultant at Parametrix, as she presents a real-world case study of a facility struggling to meet the requirements of Washington’s Industrial Stormwater General Permit (ISGP).-Molly walks us through how her team supported a food manufacturing site that faced multiple benchmark exceedances, including copper, zinc, turbidity, and visible oil and grease. You’ll hear how they addressed issues such as poor BMP implementation, missed sampling, and gravel storage yards by implementing targeted operational changes, which led to significant improvements in stormwater quality.
