Jogi Khanna, M.D. , M.P.H. April 16 , 1986 -2- Soil samples would also be obtained and analyzed at varying depths during the drilling of this well . take this o We would like to again t opportunity to pp Y explain Caltrans ' involvement in this matter. The removal of the tank was necessitated by the imminent construction of the freeway. Caltrans is constructing the freeway under a construction and maintenance agreement with the Southern Pacific Railroad and a Right of Entry which allows us to enter and contruction on their property and to modify as necessary for construction. This agree- ment will be converted to an easement for the freeway across the railroad property and perhaps a condemnation of some of the rail- road property for freeway purposes. These actions are pending and should be resolved in the near future, however . In the meantime, the tank and the site of the tank remain the property of the Southern Pacific Railroad. Caltrans has contracted to remove the tank and has sampled and removed much of the soil beneath the tank. Further excavation did not seem practical under the existing contract because ct the low level of contamination and it was desirable to backfill the excavation to prevent accumulation of surface waters in the hole, remove the hazard of the open hole, and prepare the site for freeway construction. Agreement on this was reached at our meeting on April 1 in your office subject to the requirement for further testing of the soil and groundwater. Consequently, with regard to the three items required of Caltrans in your March 25 , 1986 letter, we ask your concurrence with the following actions: 1 . The requirement for a groundwater testing well be modified to reflect the agreement we have described above as a result of our meeting with the Central Valley Regional Water Quality Control Board. 2 . Caltrans has complied with this requirement and agrees that freeway construction will reduce and perhaps prevent percolation of surface water through the soil at the site. 3 . The construction of an elevated freeway will not prohibit further site analysis and clean up if required. CVRWQCB engineers stated that the most appropriate method of clean up would probably involve only pumping and recycling of groundwater. However, Caltrans does not accept responsibility for further site assessment and soil and/or groundwater clean up. We ask that this requirement be eliminated and suggest that this responsibility remain with the property owner, Southern Pacific Transportation Company,. It is our understanding that current law requires registration of underground tanks and compliance with abandonment pro- cedures and that your agency is the enforcement agency for this law.
