I <br /> • "Heritage Marketplace Field Evaluation: Stormwater Management StormFilter <br /> with ZPGTM Media," is a report showing all of the information collected at Site A <br /> as stated in the SMI Quality Assurance Project Plan(QAPP). This document <br /> I contains detailed information regarding each storm event collected at this site, and <br /> it provided a detailed overview of the data and project. <br /> • "Lake Stevens Field Evaluation: Stormwater Management StoiiiiFilter with <br /> ZPGTM Media," is a report that corresponds to Site E as stated in the SMI QAPP. <br /> This document contains detailed information regarding each storm collected at <br /> this site, and includes a detailed overview of the data and project. <br /> • (Public) "Evaluation of the Stormwater Management StormFilter for the removal <br /> of SIL-CO-SIL 106, a standardized silica product: ZPGTM at 7.5 GPM" is a report <br /> that describes laboratory testing at full design flow. <br /> • "Factors Other Than Treatment Performance." <br /> • "State of Washington Installations." <br /> Above-listed documents noted as"public" are available by contacting CONTECH. <br /> Applicant's Use Level Request: <br /> That Ecology grant a General Use Level Designation for Basic Treatment for the <br /> StormFilter using ZPGTM media(zeolite/perlite/granular activated carbon) at a hydraulic <br /> loading rate of 1 gpm/ft2 of media surface area in accordance with Ecology's 2011 <br /> Technical Guidance Manual for Evaluating Emerging Stormwater Treatment <br /> Technologies Technology Assessment Protocol—Ecology (TAPE).. <br /> Applicant's Performance Claim: <br /> The combined data from the two field sites reported in the TER(Heritage Marketplace <br /> and Lake Stevens) indicate that the performance of a StormFilter system configured for <br /> inline bypass with ZPGTM media and a hydraulic loading rate of 1 gpm/ft2 of media <br /> surface area meets Ecology performance goals for Basic Treatment. <br /> Ecology's Recommendations: <br /> Based on the weight of the evidence and using its best professional judgment, Ecology <br /> finds that: <br /> • StonnFilter, using ZPGTM media and operating at a hydraulic loading rate of no more <br /> than 1 gpm/ft2 of media surface area, is expected to provide effective stormwater <br /> treatment achieving Ecology's Basic Treatment(TSS removal)performance goals. <br /> Contech demonstrated this is through field and laboratory testing performed in <br /> accordance with the approved protocol. StormFilter is deemed satisfactory with <br /> respect to factors other than treatment performance (e.g., maintenance; see the <br /> protocol's Appendix B for complete list). <br /> I <br /> CONTECH-StoonFilter®GULD Maintenance Update(November 2012) Page 15 <br /> I <br />
