r SEP 24 N 8 4: C be no additional design costs, but inspection costs would be approximately another $7,000 only because you are adding on another 2 weeks of inspection time. Director Pinto went on to explain the difference between an industrial -and municipal well, noting. that the municipal well is built with a casing, and if you are going.to do an industrial well, you put another casing inside of it and put protection between those 2 casings to further prevent any possible leaks. Actually, you are building a double liner. Commissioner Scurlock pointed out that the extra casing does reduce the diameter significantly, and Director Pinto concurred that when you design the municipal well, if you are anticipating a conversion to an industrial well, then you have to design with that in mind, i.e,, the municipal well would be 24" and with a casing, it would be around 20".. This will be looked at much closer in design, What we want to decide today is whether to make this an industrial well immediately, and Director Pinto felt confident an industrial well will be needed in the future. Chairman Bird inquired what the determining factor is as to whether you go municipal or industrial. Commissioner Scurlock advised that it simply is what you put down it. For instance, if it is brine or leachate discharge in certain concentrations, it triggers an industrial well. He personally felt there is no question we should go ahead with preparation for industrial, especially with the extra protection it offers, and Director Pinto advised tha.t the thinking on the environmental side is that all wells should be built to the industrial grade. Commissioner Eggert asked about projections if you did the second phase - how many years from this might you do it and what effect would that have on construction costs. Director Pinto felt the driving force as to whether this well should be industrial is not a wastewater issue; it•becomes a landfill issue and a water issue. Later in the agenda we are talking about some expansion of our water plant, and it would greatly enhance our permitting capabilities for the water plant if we could just say we are taking it to a deep well. Fie noted that getting discharge permits now is very difficult, and even if we were to start today, it will be two years down the line for either a municipal or industrial well. Director Pinto at this point recommended that if we felt we wanted to spend the money, we should put the industrial well in without any pipe lines to the water plant because we can do that when needed. He advised that the important part in the permitting issue that is directly reflected in the engineering 68 M
