Statement of Facts Forward, Inc. Page 2 During the spring of 1984, the ponds were cleaned, and the dried sludge and contaminated soil were excavated to a depth of one foot beneath the ponds and placed into Trench 4 of WMU-A. Removal reportedly was completed during October, 1984. A temporary earthen cover was placed over WMU-A. The facility submitted the Closure Plan for WMU-A in September, 1987. After review of this plan by RWQCB and DHS, a Notice of Deficiency was sent to Forward, Inc. to request additional information for the closure. The additional information was submitted in April, 1988. After review of the Closure Plan and addendum to the Closure Plan with response from RWQCB, a Closure Plan package was compiled. The Closure Plan was approved on July 29, 1988, by DHS and EPA after a 30 day public notice period. Modifications to the closure plan, including additional groundwater monitoring wells and a modification of the clay cover, were submitted and approved on April 1989 after a 30 day public notice period. The current proposal is for a Post Closure Monitoring permit which is required by State and Federal regulations when hazardous waste is left in place and capped. The Part A application, Post Closure Plan, Notice of Deficiency and Post Closure Plan Addendum are included in the public notice package. The Post Closure Permit will make the Plan an enforceable document and specify additional requirements. Post Closure Plan/Permit Description The Closure Plan as approved in April 1989, after a 30 day public notice, consisted of an engineered clay cover system for the hazardous waste landfill unit and a groundwater monitoring system. State and Federal regulations require that the cover system and groundwater monitoring system be maintained and monitored for a minimum of 30 years. The plan consists of the following: 1) Periodic sampling and analysis of groundwater wells; 2) Inspection of cover integrity including rodent intrusion, subsidence, and erosion; 3) Repair of any breaches of cover integrity; and 4) Reports to DHS, at least annually, of groundwater sampling results and inspection and repair procedures.
