northwest of the site. - <br /> Ground-water resources are utilized for the public supply and for <br /> nearby private residential supply. Thus, releases from this site <br /> could potentially affect the public potable water supply. <br /> 4.5 CURRENT USE OF THE SITE <br /> The Pitkin Iron Limestone Division site is presently owned by <br /> Pitkin Iron and the facility is idle. Mid-Continent Resources <br /> has provided the State of Colorado with a secured lien against <br /> the rockdust planes and the associated real estate. This lien, <br /> valued in 1988 at $3,000,000, is the reclamation bond held by the <br /> State for the Coal Basin Mine. The Coal Basin Mine is located <br /> several miles southwest of the site, on the west side of the <br /> Crystal River Valley. The mine was shut down during the early <br /> 1990s, and the corporation has declared bankruptcy. Because the <br /> ,. corporation is bankrupt and because the mining permit was <br /> revoked, the site reclamation required at the coal mine may be <br /> performed by the State of Colorado. The State may liquidate the <br /> Pitkin Iron Limestone Division property in order to defray the <br /> cost of reclamation of the coal mine property. <br /> 4.6 FORMER USE OF THE SITE <br /> As is noted in section 3. 3 .1, R.D. Piland and Associates <br /> Consultants interviewed two long-time employees of Pitkin Iron to <br /> develop its understanding of the previous site use. The <br /> following paragraphs summarize R.D. Piland and Associates <br /> Consultants' understanding of the previous site use, based upon <br /> interviews with the former employees. <br /> Pitkin Iron occupied the site for approximately 20 years as a <br /> crushing and bagging facility, beginning in 1971 and ending in <br /> 1992. During peak production, the plant employed about 12 <br /> people. Pitkin Iron utilized the site for production of <br /> limestone dust, magnetite dust, packwall aggregate, and nahcolite <br /> dust. The following processes were involved: <br /> Limestone crushing, drying, bagging, and bulk loadout; <br /> Nahcolite crushing, drying, bagging, and bulk loadout; <br /> Packwall aggregate crushing, drying, bagging, and bulk <br /> loadout; <br /> Magnetite crushing, drying, bagging, and bulk loadout. <br /> The crushed limestone and magnetite were used for dust control <br /> and to make packwall roof support for underground coal mining. <br /> The nahcolite was processed for NATECH Corporation for an unknown <br /> use. <br /> 18 <br />
