Please keep the Watchdogs <br />informed regarding the DMG's progress in the bonding for the cemem kiln demolition <br />and disposal. <br />Less than a month after the DMG inspection, Ms.Gabi Hcefler and Ms. Pamela Mihnce, <br />Boulder County Health Department, conducted an unannounced "Complaint <br />Investigation for Fugitive Dust" on September 30, 2002 at Cemex-Lyons. A copy of this <br />investigation is enclosed <br />The last several months have been a back slide. Plumes are still present from the CKD <br />disposal pit and from the factory complex. The investigation by Ms. Hcefler and Ms. <br />Mihnce confirms our suspicions that housekeeping problems are still issues. The <br />improper handling of materials in the clinker pit; and the lack of compliance for cleaning <br />up piles of dust noted in previous inspections may well have been the source of the recent <br />plumes blowing off the company's properly into the community. <br />This week, three plumes were reported to the Boulder County Health Department and to <br />Cemex-Lyons on October 6, 2002. The compliance manager at the facility seeks refuge <br />behind the 30 mph regulation. The community; however, has no refuge from Portland <br />cement dust blowing in the wind <br />One of the problems with this industry coming into compliance with an effective fugitive <br />dust control plan could be that most inspections are "announced," which gives the plant <br />time to clean up their housekeeping problems before the inspectors come. <br />The St. Vrain Watchdogs have been stewards of this area for several years out of <br />necessity not choice. No one from the county or the State is within visibility of this plant <br />to directly see these dust events, so we continue to have to alert government officials such <br />as you. We would rather be living our lives in the peace and beauty of this gem of a <br />valley. We hope that the practice of giving this company advance notice that an <br />°Prorset Mtmt'r ebsett m~w,r Mmrt r~~ai.h+spar and~ow mugs.^ <br />
