The approved plans Drawing C- <br />2.2 identified a 8' x 16' Contech Stormfilter using ZPG media and a Hydrodynamic Separator model CD52015-4-C both <br />sized for 0.65 cfs flow. This equipment meets DOE GULD criteria and City standards. <br />The proposed equipment is Kristar FlowGard Perk Filter using ZPC media and a Hydrodynamic Separator model DD-4 <br />both sized for 0.65 cfs. This equipment also meets DOE GULD criteria and would be equal or better than the Contech <br />equipment. <br />The Kristar sales rep (Skip Short) met with me today, furnished copies of product literature and confirmed the <br />equipment sizing for the subject project. I verbally OK'd the equipment substitution. <br />Dave <br />David Voigt, P.E. <br />Senior Engineer, Project Manager <br />City of Everett, Public Works <br />Phone 425-257-8983 <br />Fax: 425-257-8882 <br />Email.� dvoiqt(a�ci.everett.wa.us <br />
