It <br />hydrologic balance, we request that the operator show what impact their mining activity <br />has had on the 100-year flood water surface elevations and floodplain functions through <br />a FEMA approved LOMR prior to DMRS releasing the reclamation permit. <br />a ,DRMS Rule 34-32.5-116(4)(i) requires that areas outside of the affected land shall br, <br />protected from damage occurring during the mining operation and reclamation. Mining <br />and reclamation activities may have changed the conveyance of the floodplain in the <br />100-year flood. Since the currently mapped floodplain extends beyond the operator's <br />property, the potential exists for surrounding property owners to be impacted or even <br />damaged by the mining and reclamation activities that have occurred on the operator's <br />property. The operator can reduce their liability by obtaining a FEMA approved LOMR <br />which documents the impacts that mining has had on the FEMA mapped floodplain. <br />To summarize, in order to be consistent with applicable Federal, State, and Local <br />floodplain regulations, Weld County requests that the DRMS place a condition on the <br />amended permit to require a FEMA approved LOMR prior to the release/vacation of the <br />DRMS permit. This requirement will provide evidence that the mining operation has not <br />adversely impacted the hydrologic balance or adversely impacted properties outside of <br />the affected land from damage caused by the mining and reclamation operations. <br />Sincerely, <br />Cla immi, P.E., CFM <br />Drainage and Floodplain Engineer <br />Weld County Public Works <br />Original: Michael Cunninghanle, DRAIS <br />CC: Garrett Varra, Varra Compaides, 8130 Gage SI, Frederick, CO 80516 <br />him Ogle, PJnnniugScrvices <br />Page 2 of 2 <br />MAPLANNING - DEVELOPMENT REVIEW\7-DayCompletenessReviews\201 0\PA1 0-067 Floodplain Comments to DMRS 4-19-11.docx
