The following is an itemized list of our response to the hazardous waste violations for the Louise Avenue Water Treatment Facility: Violation#101 Managed a hazardous waste without an identification number. The City has an identification number, which is inactive. The City has submitted an application to reactivate identification#CAL000379085, which is attached. Violation#105 Failed to determine if a waste is a hazardous waste or retain waste analysis on site for 3 years. On May 25, 2016, a waste analysis was performed by BSK Laboratories for both the filter cake and the liquid from the filter press (filtrate); see attached analysis. The analysis is now kept on site inside the operations building. The summary of violation indicated the liquid from filter press was discharging into the storm drain. This is incorrect and the liquid, which is water is actually being discharged into the sanitary sewer drain. All barrels on the property,whether cut in half or not had been properly rinsed and cleaned after all hazardous material was used. The City had kept the barrels on site until they could be properly dispose, or used as garbage and recycling cans. When the barrels are rinsed they are triple rinsed with water and the water used to triple rinse the barrels is captured and emptied into the spray rig, which is used to spray pesticide. The half-cut barrels that had a liquid in them was rain water caused by recent rain events. These half-cut barrels had previously been rinsed and cleaned prior to rain water accumulating in them. After the inspection and concern from EHD the City retrieved all barrels, emptied all rain into the sanitary sewer from the barrels, and took them to San Joaquin County for recycling; see attached receipt and recycling program information. The ferric chloride tank which stores ferric chloride for the removal of arsenic from the water supply had leaked into the secondary containment area and also sprayed ferric chloride onto the rocks surrounding the containment. The leak was caused by a break in the chemical feed line. Ferric Chloride caused excessive staining to the rocks and the rocks remain in place. The ferric chloride, which leaked into the secondary containment was cleaned up by spraying down with water and using the vactor to pick up the water and ferric chloride. The vactor emptied the ferric/water into the 20-yard sludge storage container. The vactor was rinsed and scrapped with water to clean, and the water was dumped into the 20-yard storage container. The City also moved the rocks that had been sprayed with ferric chloride, and removed any soil containing ferric chloride with a shovel and placed in the bucket of a tractor. The bucket of the tractor emptied the waste into the 20-yard storage bin. The rocks were put back in place, but still show the staining of ferric chloride. See attached photo of ferric chloride tank area. Violation#106 Failed to prepare and implement a contingency plan. The City has completed and implemented a contingency plan, and a copy is attached. Violation#107 Contingency plan is incomplete. The City has completed and implemented a new contingency plan, and a copy is attached.
