O'Connor <br /> Re : King Coal Mine Raptor Protection <br /> Dear Peter: <br /> This letter is in response to your request concerning the raptor <br /> protection practices currently in effect at King Coal Mine . <br /> To our knowledge , there has never been a case of raptor <br /> electrocution at our mine. Due to the very small layout of our <br /> surface high voltage facilities , any large bird electrocution <br /> would be immediately noticed. We attribute this lack of raptor <br /> electrocution primarily to the surrounding topography which <br /> consists of high , steep hillsides which virtually surround the <br /> • mine site . To quote the publication entitled "Suggested Practices <br /> for Raptor Protection on Powerlines" distributed by Rapture <br /> Research Foundation , Inc . , "The use of powerline poles as perch <br /> sites varies according to topography, season and abundance of <br /> prey. Powerlines that traverse steep and broken terrain , where <br /> many natural perch sites are available, receive little ust. <br /> compared to those in flat , broad valleys where natural perch <br /> sites are absent. " <br /> In addition to topography making our powerlines unfavorable for <br /> use as raptor perches , exhibit No. 1 of the aforementi.onetl <br /> publication, concerning the use of wood crossarm braces , is also <br /> in effect . <br /> To the best of my knowledge, there are no other situations at the <br /> King Coal Mine site which endanger the raptor population in any <br /> way. <br /> If there are any questions in this matter, please contact Tom <br /> Bird at 303/385,452-9 <br /> Sincerely, <br /> Tom Bird <br /> Mine Superintendent <br /> June 1995. <br />
