• air quality standards in tlic vicinity of t:i.ne 1 and fipple 3. <br />Additional control measures implemented by Energy Fuels have <br />brought these sources into compliance as indicated. A de- <br />scription of the control measures added by Energy Fuels a-:: <br />their resultant parameters as used in the air quality stud; <br />are presented below. ' <br />The use of Cohere::, or other dust suppressant of comparable <br />effectiveness, to control road dust around ;fine 1 would be <br />expanded to achieve an average of 85`; control efficiency <br />for haul roads. This control program would supplant the <br />i <br />existing use of Coherex and wataring. <br />At Tipple 3, an expanded water spray system with antifreeze <br />added during winter months would be used to spray raw and <br />processed coal at all times, 12 months a year. In addition <br />I to spraying the raw coal at the receiving bin, spray points <br />ti would be added before the prir:.ary crusher and secondary <br />J crusher/screening station and at the transfer station be- <br />[weep the stockpile and load-out bin. It is assumed ChaC <br />the watering system will provide a 50% control efficiency <br />throughout the year on emissions from receiving, crushing, <br />screening, transfer and conveying at Tipple 3. <br />Tables 4-19 indicate [he average daily and worse case daily <br />emission rates for all phases and areas of Energy Fuel's <br />mining operation. As indicated in the proceeding paragrapi;s <br />and as~confirmed by Energy I'ue15 (personal communications, <br />• 10/L4ilA) the Energy Fuels operation is in eompliancc with <br />78 <br />,.._.. _. <br />
