I <br /> Applicant's Use Level Request: <br /> General use level designation as a Basic, Enhanced, and Phosphorus treatment device in <br /> accordance with Ecology's Guidance for Evaluating Emerging Stormwater Treatment <br /> Technologies Technology Assessment Protocol—Ecology(TAPE)January 2011 Revision. <br /> Applicant's Performance Claims: <br /> • The MWS—Linear Modular wetland is capable of removing a minimum of 80-percent <br /> of TSS from stormwater with influent concentrations between 100 and 200 mg/l. I <br /> • The MWS—Linear Modular wetland is capable of removing a minimum of 50-percent <br /> of Total Phosphorus from stormwater with influent concentrations between 0.1 and 0.5 <br /> mg/l. <br /> • The MWS—Linear Modular wetland is capable of removing a minimum of 30-percent <br /> of dissolved Copper from stormwater with influent concentrations between 0.005 and <br /> 0.020 mg/l. <br /> • The MWS—Linear Modular wetland is capable of removing a minimum of 60-percent <br /> of dissolved Zinc from stormwater with influent concentrations between 0.02 and 0.30 <br /> mg/l. <br /> Ecology Recommendations: I <br /> • Modular Wetland Systems, Inc. has shown Ecology, through laboratory and field- <br /> testing, that the MWS - Linear Modular Wetland Stormwater Treatment System filter <br /> 111 <br /> system is capable of attaining Ecology's Basic, Total phosphorus, and Enhanced <br /> treatment goals. <br /> Findings of Fact: I <br /> Laboratory Testing <br /> The MWS-Linear Modular wetland has the: I' <br /> • Capability to remove 99 percent of total suspended solids (using Sil-Co-Sil 106) in a <br /> quarter-scale model with influent concentrations of 270 mg/L. I <br /> • Capability to remove 91 percent of total suspended solids (using Sil-Co-Sil 106) in <br /> laboratory conditions with influent concentrations of 84.6 mg/L at a flow rate of 3.0 <br /> gpm per square foot of media. 111 <br /> • Capability to remove 93 percent of dissolved Copper in a quarter-scale model with <br /> influent concentrations of 0.757 mg/L. I <br /> • Capability to remove 79 percent of dissolved Copper in laboratory conditions with <br /> influent concentrations of 0.567 mg/L at a flow rate of 3.0 gpm per square foot of <br /> media. <br /> • Capability to remove 80.5-percent of dissolved Zinc in a quarter-scale model with <br /> influent concentrations of 0.95 mg/L at a flow rate of 3.0 gpm per square foot of media. <br /> • Capability to remove 78-percent of dissolved Zinc in laboratory conditions with influent <br /> concentrations of 0.75 mg/L at a flow rate of 3.0 gpm per square foot of media.
