PORTLAND, Ore., March 7, 2005 (PRIMEZONE) -- The Washington state Department of Ecology and New Jersey Department of Environmental Protection now allow the StormFilter(r) for use in treating stormwater runoff as a stand-alone BMP. Washington's issuance of a General Use Level Designation (GULD) for Basic Treatment, and the New Jersey Extension Approval to Conditional Interim Certification, make the StormFilter the first and only proprietary BMP allowed for use as a stand-alone for total suspended solids (TSS).
New Jersey is one of the states participating in the Technology Acceptance Reciprocity Partnership (TARP), a workgroup that has collaborated to develop guidelines for evaluating emerging stormwater technologies. Washington, which has developed its own program for testing stormwater BMPs, and the TARP states are leading the stormwater industry with their efforts to define guidelines for monitoring, sampling, and analyzing the performance of emerging treatment technologies. These programs will greatly benefit jurisdictions across the country as they can look to Washington and the TARP workgroup to assist in treating stormwater runoff.
In Washington, the StormFilter was evaluated through extensive field monitoring over a two year period at multiple sites. With influent particle size distributions ranging from silt to silt loam, it was demonstrated that the StormFilter consistently satisfied Washington's stormwater treatment goals for the removal of total suspended solids utilizing ZPG(tm) media at an individual cartridge flow rate of 7.5 gpm. ZPG is a blend of three types of filter media: zeolite, perlite and granular activated carbon.
Stormwater Management is currently working to complete a similar evaluation in the field for the StormFilter in New Jersey.
Proven to Work in the Field
The stand-alone designation marks a significant achievement for Stormwater Management, as the StormFilter has met Ecology's Basic Treatment standards through rigorous field testing. "For 10 years, Stormwater Management has committed time and energy to demonstrating that the StormFilter can achieve Ecology's Basic Treatment requirements," said Senior Vice President Jim Lenhart. "We are now applying the research and engineering principles we have developed to demonstrate the StormFilter's performance in other states, including the TARP states."
The StormFilter removes the most challenging target pollutants - including TSS, soluble heavy metals, oil and grease, and nutrients - through a patented passive filtration system that uses a variety of sustainable media. Proven to be highly reliable and easy to maintain, the StormFilter is recognized across the US as a versatile BMP. With over 30,000 cartridges installed and over 600 BMP approvals, this stormwater treatment solution meets even Washington's stringent standards.
