lliiki <br /> ACUVated Car on U ilizatlon <br /> ,- The initial charge of 4,000 pounds of virgin 4 x 6 mesh activated carbon in reactors 1 <br /> and 2 were changed out and replaced with 4,000 pounds of virgin 4 x 6 mesh <br /> activated carbon on January 19, 1990. The partial saturation of the third reactor on <br /> January 19, 1990 did not warrant changeout since the third reactor is solely for the <br /> purpose of trapping fugitive emissions from the first two reactors. The carbon in all <br /> three reactors became saturated on February 5, 1990 and was replaced February 14, <br /> 1990. Another carbon changeout was required on March 16, 1990. The rate of carbon <br /> utilization has been less than one pound per day since June 11, 1990. Tltius, <br /> changeout of the carbon should not be required throughout the remaining remediation <br /> effort. <br /> a <br /> F <br /> t <br /> i <br /> 6 <br /> VAPOR EXTRACTION TECHNOLOGY, INC. <br />
