Kilgore Companies, LLC dba Elam Construction <br /> 556 Struthers Avenue, <br /> Grand Junction, Colorado 81501 <br /> August 8th, 2019 <br /> Mr.Tyler Adams <br /> US Army Corps of Engineers <br /> Colorado West Regulatory Branch <br /> 402 Rood Ave., Room 142 <br /> Grand Junction, CO 81501 <br /> Gehrman Pit—Yampa River Breach <br /> Dear Mr.Adams: <br /> We would like to notify the United States Army Corps of Engineers (COE)that on June 22,2019 a portion <br /> of the Yampa River located approximately 2 miles east of Craig, Colorado had flooded and subsequently <br /> breached into the Gehrman Pit (Mine ID per the Colorado Division of Reclamation, Mining&Safety M- <br /> 2009-078).The latitude and longitude of the inflow breach is as follows: Lat: 40.503257*, Long:- <br /> 107.507932'. <br /> Based on the weather experienced in the high country(Steamboat Springs, Colorado)with a record high <br /> precipitation on June 21, 2019,followed with higher temperatures,created an extreme amount of <br /> runoff. The water level had surpassed the rivers embankment and flooded into the Gehrman Pit. <br /> Thereafter,the water level did not dissipate causing the erosion of the Gehrman Pit back to the rivers <br /> bank ultimately diverting the Yampa River channel through the Gehrman Pit.The Gehrman Pit is now <br /> captured by the Yampa River and is not flowing in its natural meandering path.We are now contacting <br /> COE to take the necessary steps in curing this diversion to the Yampa River, and eventually re-armoring <br /> the breached embankment. <br /> Elam originally expected the river to eventually subsided and continue on its natural course, however <br /> that is not the case. In the interest of maintaining a working partnership with the COE, Elam has <br /> retained the services of Greg Lewicki and Associates to act on our behalf in this matter and resolve this <br /> issue. We want to emphasize that Elam is committed to working with the COE in a cooperative manner <br /> and look forward to resolution of this issue. <br /> Sincer ly, <br /> V <br /> Jim Doody <br /> Environmental Manager <br /> Kilgore Companies, LLC dba Elam Construction <br /> 556 Struthers Avenue, Grand Junction, Colorado 81501 <br /> Jim.Doody@elamconstruction.com <br /> 970-242-5370 <br /> Xc: Mr.Travis Marshall, Colorado Division of Reclamation, Mining&Safety(DRMS) <br />
