Banks and Gesso, LLC <br />The air emissions testing proved that all air quality standards were complied with. A <br />toxicological report (prepared by Dr. Scott Klingensmith) concluded that no public health <br />hazard would result from fire burning. At the request of the Boulder County Health <br />Department, the Federal Agency for Toxic Substances and Disease Registry (A Division <br />of the Centers for Disease Control and an independent and highly qualified group) <br />reviewed the emissions test results and toxicology report. ATSDR concluded there is no <br />public health hazard associated with the fire burning. <br />6.0 Division of Minerals Geology Request for CKD Testing <br />The Division requested that Cemex sample and analyze CKD both before and during the <br />trial fire bum to determine if significant changes in CKD chemistry occurred. The <br />Division regulates CKD disposal on-site through the mining and reclamation permit. The <br />issue of concern stated by the Division was protection of the ground water resource in <br />the vicinity of the disposal cell. Cemex contacted Banks and Gesso, LLC to implement <br />the sampling and analysis. <br />Paul Banks attempted to determine the parameters to be analyzed in the lab through the <br />following efforts: <br />- Consultation with Richard Henry, URS Corporation <br />- Consultation with Scott Klingensmith, Flatirons Toxicology <br />- Consultation with Paul Ottenstein, Air Pollution Testing (they pertormed the air <br />emissions testing) <br />- Consultation with Harry Posey, Division of Minerals and Geology (who also <br />discussed the matter with representatives of Colorado Department of Public <br />Health and Environment) <br />- Internet research of Environmental Protection Agency publications <br />The results of this work provided no list of analytes specific to the use of tires as a <br />supplemental fuel source so we decided to analyze for a very comprehensive list of <br />parameters including: <br />' - organics <br />- inorganics <br />- metals <br />' - major ions <br />- radionuclides <br />- dioxins and furans <br />The lab costs were approximately $1,500 per sample. Two CKD samples were collected <br />and analyzed before tires were burned and two CKD samples were collected and <br />analyzed during the trial fire bum (a total of 4 samples). This is a very comprehensive <br />and proactive approach in terms of the ultimate goal of protecting ground water quality. <br />CKD from the baghouse that is destined for haulage to the disposal cell is emptied <br />directly from the baghouse through a chute and into a haul truck. All four samples were <br />taken directly from the haul truck containing freshly loaded CKD and delivered to the lab <br />that day. Sample jars were provided by the lab and chain of custody forms were <br />properly completed. <br />02053 Cemex, Inc. CKD Testing ¢ <br />
