Before system start up, the operator should visually inspect the pumps for leaks, signs <br /> of vandalism and fluid levels. <br /> 3.4.4 Water Quality Monitoring Box <br /> Both automated and hand testing equipment should be calibrated before every shift and <br /> documented. Chitosan lines should be checked for leaks and secondary containment <br /> checked for any spills. If any of the safety equipment was used during a shift, notify the <br /> NSC field manager so replacements can be ordered. <br /> 3.4.5 Sand Media Filter Unit <br /> Sediment build up on the sand filter media is back washed with clean treatment system <br /> filtrate and routed back to the pre-treatment tanks. Over a period of time, sand can be <br /> washed out with the back flush to the point additional bags need to be added. This <br /> material is readily available at a number of supply stores. <br /> 3.4.6 Connection Lines and Hoses <br /> A visual walk of the system and piping should be done during every day of operation. <br /> Extra pipe and fittings will be kept onsite to make any repairs. <br /> 3.4.7 Personal Protective Equipment <br /> System operators should have typical site safety equipment; hard hat, safety glasses, <br /> hearing protection available, gloves, high visibility clothing and steel toe boots. An eye <br /> wash is mounted in the WQMB near the chemical storage area. <br /> 3.4.8 Filtration System Safety <br /> Only Northwest Soil Cement LLC personnel or others, that are on the Washington State <br /> Department of Ecology Approved Operator list shall operate and maintain the filtration <br /> system as well as handling of the treatment chemicals. <br /> Temporary over land piping is being used to convey water throughout the filtration <br /> system. <br /> The filtration system is designed to be operated in multiple shifts over a 24-hour period. <br /> At times this will require operation during periods of darkness. The Water Quality <br /> Control Box is internally lit for night time operation. Light plants will be positioned to <br /> properly light all of the designated pedestrian corridors if this becomes necessary. <br /> 3.4.9 Treatment Chemical Handling and Storage <br /> City of Everett <br /> EVERETT Reviewed for Permit 10/20/2021 <br /> WASHINGTON <br /> 14 <br />
