Document Description
Phibro-Tech Inc. (PTI) requested the DTSC to approve a Class 2 Permit Modification (titled Revised Request for Determination of Class 2 Permit Modification for Wastewater Tank Replacements, dated Sept. 22, 2016. The proposed Class 2 Permit Modification (Project) allows for the on-site construction of four new wastewater treatment tanks in different locations which replace the existing waste water tanks W-1, W-2, W-3, and W-4 to enable the Pond 1 closure activities to commence without interrupting the ongoing operation of the facility, and expansion of existing on-site containment areas to accommodate wider aisle space (30 inches) in two permitted container storage areas CS-1 and CS-2. For the proposed replacement of waste water treatment tanks W-1 and W-2 and W-7 and W-8, replacement tanks will be installed in a different location, and will be named W-7 and W-8 and tanks W-1 and W-2 will be closed. Tanks W-7 and W-8 will be of the same nominal capacity as tanks W-1 and W-2. To make the location available for the new W-7 and W-8 wastewater treatment tanks, it is necessary to remove and replace an operating filter press (FP-#2) with a new, similarly designed filter press, designated FP-#2A. Design details for tanks W-7 and W-8, the new tank containment area, container pumping station, and filter press FP-#2A were included in the Class 2 Permit Modification submittal. When tanks W-7 and W-8 become operational, tanks W-1 and W-2 will be simultaneously shut down so that there will be no change in operational capacity. For the proposed replacement of waste water treatment tanks W-3 and W-4 with J-6 and J-7, the new tanks J-6 and J-7 will be constructed and Tanks W-3 and W-4 will be closed. Tanks W-3 and W-4 and the Filter Press FP-#2 currently operate under a 1988 variance issued from the Dept. of Health Services (DTSC's predecessor). They are located adjacent to the Pond 1 containment area. The former Pond 1 area is currently used for W-1 and W-2. When Pond 1 closure commences, soil will be excavated up to about 12 feet below the base of tanks W-3 and W-4. Removing these tanks prior to the excavation associated with Pond 1 closure will increase safety during excavation and associated closure activities. Prior to removal of Tanks W-3 and W-4, new tanks J-6 and J-7, each with the same capacity (12,500 gallons) as tanks W-3 and W-4, will be installed in a new J containment area. Design details for Tanks J-6 and J-7 and the containment area are provided as part of the Class 2 permit modification request. Once Tanks J-6 and J-7 become tanks W-7 and W-8, are operational, the Facility will be able to initiate Pond 1 closure. When tanks J-6 and J-7 become operational, tanks W-3 and W-4 will be simultaneously shut down so that there will be no change in operational capacity. Modifications are also requested for increasing the physical size of two existing container storage areas, CS-1 and CS-2, without changing the currently authorized storage capacity in Permit No. 91-3-TS-002. PTI submitted this Class 2 Permit modification request to provide a minimum of 30-inch aisle space, rather than the current 24 inches. In addition, the expanded CS-1 area is adjacent to the new J-area, and it would be preferable to modify CS-1 concurrently with the new J-area construction for replacing Tanks W-3 and W-4. As the closure of Pond 1 is a priority, work to expand the surface area of the containment areas will be scheduled so as not to delay the implementation fo installing new tanks and associated tank containment areas for W-7, W-8, J-6, and J-7 and for initiating Pond 1 closure.
