As with existing hospitals and clinics however,the new operation <br /> must comply with pretreatment requirements including the Prohibited Discharge Standards specified in COE's <br /> pretreatment ordinance (3070-08/EMC 14.40).This includes source controls for wipes or various other <br /> debris/trash/solids that don't belong down drains(i.e. "...greater than one quarter inch (1/4")"), no medical waste <br /> discharges unless specifically authorized by the Director, no discharges with pH less than 5 or greater than 11 (could <br /> require buffering/attenuation of drainage from labs,for example), among others. Complete list of PDSs is in 14.40.050). <br /> Proper storage, handling and disposal of various chemicals, medications, toxics etc. is of course also required. In the <br /> checklist(p. 16-17, Part 7.a.3)—Table 1), it appears they (contractor) listed materials to be used during the project's <br /> development or construction. But it does not appear they have listed any(all)toxic or hazardous chemicals that might <br /> be stored, used or produced "...during the operating life of the project." <br /> Points of contact for the project are welcome to contact our office as needed for clarifications on requirements. <br /> Charles <br /> EQD/IPT <br /> 425-257-8224 <br /> 1 <br />
