The current status of the ponds must be shown accurately on a map. The 1994 closure plan shows the pond in the southeast comer of All Pure's fenced area as being lined. This pond was not lined when I visited the site in January and March of 1996. The currant and past uses of each pond also must be reported. The closure plan needs to be complete. Appendices A and B :vere missing from the closure plan. Of particular importance is Appendix A which includes the i; ell logs for the four monitoring wells on the All Pure facility. The closure plan should include the means of closure and ;ost closure r.: "c� for all pods to be closed. It is appropriate to include this now since WDks will not be issued for the ponds to be closed. The 1994 closure plan stated that All Pure intended to build a warehouse on top of the site of the closed ponds. If this is still planned, a schedule for construction should be included. If the building will not be constructed for some time, if the building is not planned, or if the building will not cover the area of all ponds closed, then All Pure needs to prepare an alternative plan for post closure maintenance of the ponds. Additional details which must be provided in the closure plan include the method of emptying the ponds, method of soil sampling, analyses to be performed on the soil samples, and a regrading plan. A schedule for closing the ponds is needed, including dates for emptying the ponds, soil sampling, reporting results of the sampling with a work plan to remove or remediate any contaminated soils, and regrading. Please submit a revised closure plan which addresses the above comments no later than 7 June 1996. If you have any questions you may call me at(916) 255-3048.
