I <br /> have a bulk density ranging from 6.5 to 8.5 lbs per cubic foot and particle <br /> sizes ranging from 0.09" (#8 mesh) to 0.38" (3/8" mesh). <br /> • Zeolite Media: Zeolite media shall be made of naturally occurring <br /> clinoptilolite. The zeolite media shall have a bulk density ranging from <br /> 44 to 50 lbs per cubic foot and particle sizes ranging from 0.13" (#6 mesh) <br /> to 0.19" (#4 mesh). Additionally,the cation exchange capacity(CEC) of <br /> zeolite shall range from approximately 1.0 to 2.2 meq/g. <br /> • Granular Activated Carbon: Granular activated carbon (GAC) shall be <br /> made of lignite coal that has been steam-activated. The GAC media shall <br /> have a bulk density ranging from 28 to 31 lbs per cubic foot and particle <br /> sizes ranging from a 0.09" (#8 mesh) to 0.19" (#4 mesh). <br /> Applicant: Contech Engineered Solutions <br /> Applicant's Address: 11835 NE Glenn Widing Dr. <br /> Portland, OR 97220 <br /> Application Documents: <br /> The applicant's master report, titled, "The Stormwater Management StormFilter <br /> Basic Treatment Application for General Use Level Designation in Washington", <br /> Stormwater Management, Inc.,November 1, 2004, includes the following reports: <br /> • (Public)Evaluation of the Stormwater Management StormFilter Treatment <br /> System:Data Validation Report and Summary of the Technical Evaluation <br /> Engineering Report(TEER) by Stormwater Management Inc., October 29, 2004 <br /> Ecology's technology assessment protocol requires the applicant to hire an <br /> independent consultant to complete the following work: <br /> 1.
