WASTE DISCHARGE REQUANTS NO. 5-01-114 -4- PILKINGTON NORTH AMERICA, INC. PILKINGTON GLASS FURNACE FACILITY SAN JOAQUIN COUNTY dispose of approximately 1.7 million gpd of process water. Because the land application areas require improvements, technical reports documenting preparation of the land areas for the application of wastewater are required prior to increasing allowable flow rates. 25. Industrial wastewater is discharged to the sump lift station prior to being discharged to the concrete lined storage pond, and subsequent land application areas. The storage pond and land application areas are presented on Attachment B, which is attached hereto and made part of this Order by reference. 26. The land application areas consist of the lawn areas (11.4 acres), Site A flood irrigation area (42 acres), and Site C sprinkler area(8.5 acres). Crops are not presently grown on Sites A or C. The Discharger is proposing adding Site B (13.5 acres) to the land application area. This area may not be used until the Executive Officer approves the report required by Prohibition A.8. The land application areas are not bermed with the exception of a partial berm on the north side of Site A. 27. Staff conducted a site inspection on 3 April 2001 and found that wastewater is not being evenly applied throughout Site A. Instead it has been allowed to pond and infiltrate at the east end of the field. The area is not fenced or signed to restrict access, nor is it graded to allow the even application of wastewater over the entire 42 acres. In addition, it is not bermed to the degree shown on Attachment B. 28. Site B has not been used for wastewater application in the past. Before it can be used,the Discharger will need to install pipes to transport the wastewater to the field and evenly distribute it, build berms, level the land, plant a crop, complete perimeter fencing, and install signs warning of the use of reclaimed water. During the 3 April 2001 inspection, staff found that an unknown source of water was discharging into a standpipe at the northwest end of the field. This Order requires the Discharger to determine the source of this water, and if wastewater, to cease the discharge until the field has been prepared to accept the waste. 29. The lawn application area is irrigated with wastewater daily year round. The sprinklers overspray the lawn and wet the roads within the facility. This overspray is allowed under this Order only because all stormwater falling on the facility is collected and treated with the industrial/domestic wastewater. Overspray onto areas where storm water is not collected(i.e. along Louise Avenue) is prohibited. A portion of the lawn area is fenced; however, there are no signs warning the public about the use of reclaimed water. 30. The pond has two sumps designed for pumping water into and out of the pond. The inflow pumping sump is equipped with four pumps (three 1,000 gpm and one 550 gpm). The outflow sump has four pumps (two 1,000 gpm, one 550 gpm, and one dedicated for fire suppression). Except for the fire suppression pump, the outflow pumps are manifolded to pump to the lawn area, Site A,and Site C. 31. The pond is equipped with pumps to deliver fire suppression water to the facility. A minimum of 500,000 gallons of wastewater is required at all times for fire suppression. With
