New Jersey DEP Awards Stormceptor First Online Storm Water Treatment Device Approval

Imbrium Systems announced that Stormceptor STC, an oil and sediment (hydrodynamic) separator for storm water treatment, was approved by the New Jersey Department of Environmental Protection (NJDEP) for use as an online storm water treatment device. Based on the recently updated NJDEP storm water performance testing standards, Stormceptor technology is the only hydrodynamic device that is currently allowed for use in an online configuration. According to Imbrium, this performance-based approval can allow developers to save tens of thousands of dollars while still providing the best storm water quality treatment for their projects.

“The Stormceptor STC online approval is another demonstration of innovative technology-tested to standards that validate superior performance. Designing storm water treatment systems to capture pollutants is critical, but so is retaining those same pollutants,” said Scott Perry, group manager for Imbrium Systems. “Recent updates to the state’s technology verification and certification test standards provided an opportunity to better validate overall performance of these systems. The New Jersey DEP certification letter means that land developers can have complete confidence in Stormceptor’s performance while saving precious land space as well as construction dollars in this tough economy.”

Many states and jurisdictions across North America have been relying on NJDEP’s storm water technology verification and certification process (Technology Acceptance and Reciprocity Partnership), but may be unaware of the offline requirement. Several years ago, NJDEP reviewed its test standards and discovered pollutant washout, or scour, was a major issue with most hydrodynamic separators. As a result, NJDEP quickly modified its storm water device design requirements in early 2008 to address this concern. NJDEP mandated that all storm water manufactured treatment devices were only approved as offline water quality devices unless it received new test data to a more stringent standard that verified a device would not wash out silt-sized pollutants during intense, high-flow rain events.

“We believe our scientific research and continuous innovation are benchmarks for the storm water industry to follow and New Jersey DEP agrees,” said Perry. “Stormceptor STC is the first hydrodynamic separator to exceed New Jersey DEP’s rigorous testing standard for online certification and thus civil engineers and land developers can feel confident using Stormceptor STC when they begin their next project.”
