Commissioner Macht led discussion regarding the cost of <br />changing the chiller to comply with Environmental Protection Agency <br />(EPA) requirements, which must be accomplished by the end of fiscal <br />1995. <br />Mr. Lee Kendrick, project manager at Gee & Jenson, estimated <br />the cost at $80,000. The chiller could be expected to last another <br />5 or 6 years, but the chiller's capacity will be reduced by <br />approximately 20% *when it is retrofitted to accommodate the new <br />refrigerant, which may render it inadequate to serve the building. <br />Commissioner Bird led discussion about funding a project of <br />this magnitude. r <br />Administrator Chandler explained that staff is considering the <br />possibility of recommending the use of sales tax revenue. He <br />pointed out that another problem is that sections of the building <br />will have to be shut down for a minimum of 2 weeks for each <br />section. One reason staff requested a postponement of the sales <br />tax workshop was to allow more time to deal with these issues. <br />Commissioner Macht felt that it would be in the best interests <br />of the taxpayers in this county to treat this as a capital project <br />and finance it with sales tax revenue. <br />Commissioner Adams asked whether staff will present all the <br />alternatives to the Board, which would include doing nothing, <br />retrofitting the existing chiller for the new refrigerant, <br />following the recommendations of Gee & Jenson, or constructing a <br />new building. <br />Administrator Chandler responded that the cost might increase <br />significantly if we wait for the problem to become a crisis. He <br />advised that an analysis of various alternatives will be prepared <br />for presentation to the Board. <br />Mr. Grinell reminded the Board that it is necessary to comply <br />with requirements of the Americans with Disabilities Act (ADA) any <br />time major renovations are made. <br />Administrator Chandler stated that the County has taken a <br />proactive approach to complying with ADA requirements, and that <br />should not be a problem. <br />Chairman Tippin wondered why we have all these problems with <br />air quality that did not exist in earlier times. <br />Mr. Grinell explained that years ago most buildings had <br />terrazzo, tile, or wood floors rather than carpeting; they had <br />plaster instead of drywall; and they did not have spongy ceiling <br />tiles and -other materials that soak up moisture from the air. He <br />commented that carpeting tends to hold debris that can contribute <br />to indoor air quality problems. For that reason, many architects <br />are encouraging organizations to use hard flooring rather than <br />35 <br />a 92 PnE 59 <br />
