Box 535 Somerset, Colorado 81434 Re: Request for Fugitive Particulate Emissions Control Plan Gentlemen: Your attention is directed to the Colorado Air Ouetity Control Commission's Regulation Number 1, Section III.D.(a copy is enclosed), and specifically Section III.D.1.a(i), which reads as follows: "Every owner or operator of a source or activity which is subject to this Section III.D. shall employ such control measures and operating procedures as are necessary to minimize fugitive particulate emissions into the atmosphere through the use of all available practical methods which are technologically feasible and economically reasonable and which reduce, prevent and control emissions so as to facilitate the achievement of the maximum practical degree of air purity in every portion of the State." Your attention is further directed to Regulation Number 1, Section III. D.2.d.(ii), which reads as follows: "Any owner or operator of any new or existing mining operation from which fugitive dust particulate emissions will be emitted shall be required to use all available, practical methods which are technologically feasible and economically reasonable in order to minimize such emissions in accordance with the requirements of Section III. D., of this Regulation." An invest igation resulting from complaints received by this Division concerning coal dust from the Somerset Mining Company operations at Serller~et, Colorado was conducted. The investigation revealed excessive amounts of coal dust covering the buildings and yards within the town of Somerset. Evidence of coal was noted in multiple layers in the snow accumulated on roofs. Coal was noted "peppering' snow in yards, on sidewalks, etc. In addition, interviews with occupants of one of the closer buildings to Somerset Ilinina Company's operation indicated a significant increase in coal dust emissic~lls. 5T1°~TE G~= COLC III IIIIIIIIIIIII III C ~ ~.i~ lekl•~: e/~~ ~~~ \~C ~~ 999 - 17071)7]-907k (( ~ UO)17A1J79 ~l \ :'~ • • ~ s l ~. ~ ~ ~S'X J / / e, k~ ^n , ~C 8rsc~ 4W Roma Gaemor / ~ ~-/ ~ ~ T1wm•f M.
