ACS <br />'~~ <br />October 30, 1978 <br />Statt~ of Colorado <br />Mined land Reclamation <br />1313 Sherman Street <br />Denver, Colorado 80203 <br />RE: Portland Limestone Quarry Permit Application 77-344 <br />Attn.; Mr. Roger Funston, Staff Specialist <br />A discussion prior to the Board's „<,~!,;.n,~,G approval of the subject <br />application at the September 26, 1978 meeting involved the status of <br />a fugitive dust permit for this quarry. Ideal was not prepared to <br />present facts relative to such a requisarent and offered to investigate <br />and advise. <br />Mr. R. J. Castelli, Ideal's Director of Environmental Quality, asked <br />Mr. John Clouse, Senior Air Pollution Control Specialist with the Colo- <br />rado Department of Health for a review and determination of the need <br />for a fugitive dust permit. A copy of the reply from Mr. Clouse, dated <br />October 13, 1978 is attached. Since Ideal has had no "substantial al- <br />terations" in the quarry operation after January 19, 1976, a fugitive <br />dust permit is not required. <br />Even though a fugitive dust permit is not c1>rrent requirement, Ideal <br />will continue to keep abreast of improv®ents in this field and utilize <br />equipment or processes that have a practical application to the quarry <br />operation. Mr. W. T. Springlnan, Portland Plant Manager, explained at <br />the Board Meeting that dust collection equipment is maintained on the <br />blast hole drill and crushing facilities. Fugitive dust from the private <br />quarry haul roads is controlled by the sprinkle application of water with <br />a chemical additive. <br />If additional information should be desired, please advise. <br />Sincerely, <br />~j, ~ ~~ <br />R.
