Item I, A, G - A request for a Certified Mine Map <br />as covered by 30 CCR, Subpart M was not realized; <br />rather a recommendation to combine the Ventilation <br />Map with the Mine's Certified Map. Simply, I did <br />not realize a request for the Certified Map in a <br />Ventilation Plan letter. <br />As agreed with Mr. Knepp and our Engineering De- <br />partment, three copies of the up-to-date Certified <br />Map will be submitted by June 9th. <br />5. The ventilating air at the belt portal was shown as <br />belt entry velocity as was requested in the past. <br />The belt portal is now defined as a mine opening <br />and the volume of air entering the mine as request- <br />ed. This amount has been shown. <br /> 6. The true Ean readings were entered into the fan <br />• data boxes. Mr. Knepp stated the total intaking <br /> air currents should be within 15$ of the total <br /> exhausting air currents due to-anemometer inaccura- <br /> cies. <br /> 7. Panels "E", "C", "G" and "II" are currently venti- <br /> lated by return air entering Panel "E" and venti- <br /> • lacing across "["' and "G" and exiting out the right <br /> entry of both panels "G" and "H". Directional <br /> arrows are shown on the map. <br /> 8.
