Lyons Quarry, Permit No. M-1977-208, Wildlife Resource Assessment Report <br />Dear Ms. Crosby: <br />District Wildlife Manager Sharlene Haeger reviewed the Wildlife Resource Assessment Report <br />submitted by Michael Figgs of LREP on behalf of CEMEX, Inc. for the Lyons Quarry and discussed the <br />report with'DWM Lassiter. The report lists species of concern that aze known to occur on the site: Bald <br />Eagle, Ferruginous Hawk, Black-tailed Prairie Dog, and Preble's Meadow lumping Mouse. According to <br />NDIS, the site occurs in winter range for the Bald Eagle, overall range for White-tailed Deer, and <br />summer and winter range for Mule Deer. The report acknowledges that the water in "C" Pit presents a <br />potential hazard to wildlife that may come in contact with it, due to high selenium levels and pH of <br />approximately 12. <br />Upon reviewing.mitigation options outlined in the report, DWMs Haeger and Lassiter concur with the <br />recommendation "that removal of the water, and prevention of further excess accumulation of water in <br />the pit, be implemented as a long term solution, and that the most viable option or options be pursued <br />immediately and with diligence." They acknowledge that this option will likely take two to three years to <br />implement, and.that the potential threat to waterfowl and shorebirds will decline as the water level is <br />reduced. <br />In the shorf,term,.the nunor.mitigation option to install an 8' gate on the access road and to place 8' <br />construction, #'ence along the leading edge of the bank is recommended to prevent deer from entering the <br />area and possibly contacting the water or falling into the pit. Deer are known to occasionally fall into <br />steep concrete-lined canals; the same hazazd exists at "C" Pit. It is not known if the toxicity of the water <br />reduces the. attraction to wildlife seeking a water source. <br />During the site visit, DWM Lassiter voiced a concern that a plan for "A" Pit is necessary to address <br />toxicity that maybe detected during future monitoring efforts, since wildlife is known to use that pond. <br />Since the report pertains only to "C" Pit, this issue still needs to be addressed. <br />~j:> <br />DEPARTMENT OF NATURAL RESOURCES, Russell George, Executive Director <br />WILDLIFE COMMISSION, Philip James, Chair.
