City of Stockton, which operates its own landfill. However, the general public from the City of Stockton uses the Lovelace Transfer Station, and the cities of Manteca, Escalon, Ripon and all of the unincorporated areas haul to the transfer station and it is trans- ferred to Foothill. About 93 percent of Foothill's waste comes from the Lovelace Transfer Station. Comm. Jungeblut: What is the water table in the four monitoring wells? Mr. Horton: He thought the water table was about 125 feet below the site. Comm. Jungeblut: What type of soil will you run into at the 35 -foot excavation depth? Mr. Horton: They have run into clays, clay -sand, sandy clays, inter- mittent beds of different types of material. The permeabilities have ranged from 10 to the minus 4, to 10 to the minus 9 (10 to the minus 9 being the extremely tight soils; 10 to the minus 4 being very loose soils that drain more freely). Through that 35 foot excavation they ran into some very tight clays and they intend to separate those clays and use them for constructing a liner at the bottom of the site. The State requires the liner to be constructed with a permeability of 10 to the minus 6. Some of the soils on the site are tighter than what they would be required for development of a liner. Comm. Jungeblut: With your 65 -foot -maximum ground coverage, would you get more runoff with that type after it is filled? Mr. Horton: There is a potential for an increased runoff because we are going to be decreasing the amount of water that would infiltrate into the site. The EIR recommended that we install some retention basins and we will be doing that and so that it that will slow and hold the runoff and meter it on a slower fashion. PUBLIC HEARING CLOSED Staff noted that the staff recommendation is clarified to approve the Use Permit with the conditions and findings in the staff report, rather than adopting a resolution intending to approve the project (see motion). Chairman Bozzano said that if the Commission did want to approve this, he would agree with Mr. Horton that Mr. Burnett's request concerning the toxins, anything that the County would cause would be their problem, but not if it was caused by somebody else. John Eilers brought up a good point - that the Commission should not consider that the County has already bought it, and not consider that they have been working on it for years, but it is hard not to. I* Comm. Jungeblut said he is concerned, like some of the neighbors are, with water contamination. That is a serious problem. The City of PC: 6/1/89 -7- MINUTES
