that is to build an additional 3 MGD plant, a Plant 4 and that he would not recommend building another full 3 MGD plant without interconnecting capabilities. He said there are other potentials; however, it would require working with the Regional Board to see if there are other options to put in pumping and piping that would allow the City that flexibility. He said this is done on a case by case basis because there is no written law or regulation that tells you this is how it is done. Councilmember Sanders said essentially the plants will remain separate and interconnected. Mr. Mowry said that is how they are showing it because some of the existing plants are nearly 50 years old, they are at the end of their expected life. Mr. Mowry said the question is, does the City of Colton want to invest money in repairing the old, or does it wish to build a new facility to replace the old one. This is what the City will have to decide and it must give the engineer some discretion on what you would like to see. He said the repairs to the old plant may save the City a few dollars today, but in the long run would likely cost the City more as the old plant would have to be replaced in the near future. Mr. Mowry said this is why the report is not complete, CH2MHILL is requesting that the City provide them guidance and in the next three days, they will modify the report to go in the direction that the City and the Utility Commission would like to see. Discussion took place with regard to meeting the stringent requirements of AQMD. Mr. Mowry said that he was not sure what AQMD would require; that it was important on what facilities are modified and how AQMD views the work. He said in any event a full disclosure of the work to be done will be sent to AQMD and the City will have to wait and see what they say. Councilmember Hutton asked, regarding Plant I being the oldest, if parts could be found for repairs, would it meet today's requirements of the Regional Board. Mr. Mowry replied that he was not sure because the Board would be looking at the City's ability to continue to maintain the facility. Mr. Mark Adelson, Santa Ana Regional Water Quality Control Board, stated that Plant 1, was probably capable of performing to a level necessary to produce effluent, that with further treatment, could meet Regional Board requirements. He said that because the unit has exceeded its expected design life, in particular the mechanical systems, the Board would consider that the reliability of that unit is marginal at best. Councilmember Hutton said it would be questionable then, if the City could even find replacement parts for the facility. Mr. Adelson said he was doubtful that replacement parts could be found for the system. He said it would be necessary to remove the existing mechanical systems and replace them with contemporarily designed and engineered mechanical systems. Councilmember Hutton asked Mr. Adelson if he had an opportunity to 6 JUL 1 0 1995
