• a i r ~ ~ P MpHpGE MENI SEq ti' J yN0 Lit ~. S • 20 July 1987 Mr. R1Chard L. Stenzel °WINNING MOVES" Colorado Water Resources Division 1313 Sherman St., Room 818 Denver, Colorado 80203 ~ III IIIIIIIIIIIII III RE: Sterling Sand & Gravel Co.; Home Office Mine; Amendment permit application for the Colorado Mined Land Reclamation Division. Dear Dick: Attached is a copy of the above amendment application as submitted to the CMLRD. The amendment combines four existing permitted areas into one composite permit area. The following permits are involved: M-77-439; Pit #1 M-77-440; Pit #2 M-78-256; Reclamation Pit #1 M-86-049; Seaworth Pit. • Under the amendment, areas of planned excavation and estimates of final pond extent have been revised such that the surface area of ponds as presen~ed in the original permits has changed. Our concern is to obtain written assurance from the Colorado Water Resources Division that ponds that did not require augmentation under the original permits does not require augmentation when combined by this amendment. Under Exhibit F - Reclamation Plan Map, the approximate extent of final pond surface area is portrayed. The surface area in acres is detailed for each pond under Table VIII - Pond Surface Acreage and compared with the surface area in acres of the ponds as originally permitted. Ponds created prior to 1973 are not included and are not considered affected land even though they fall within the amended permit area. Table VIII, indicates that the surface area of ponds proposed by the amendment is now less than the total surface area of ponds not requiring augmentation under the original permit. The operator requests acknowledgement that augmentation will not be required for the pond areas presented in this amendment until and unless the final surface area in acres exceeds the total surface area in acres of ponds as represented under the original permits. In such an .event, augmentation would be required and complied with to the extent that the difference between any future excess pond surface area exceeds the surface area of ponds as represented in the original permits. The maps given in the original permit which represent the the pond surface areas are compiled and included here-in for your reference. Since the Seaworth Pit (M-86-049) is under augmentation, it is not to be considered as part of the concern expressed in this letter. . Thank-you for your time and kind assistance, ~~\ ' Sincerely, Bradford Janes, President 1510 York St., Ste. 329 • Denver, Colorado 80206 • (3031393-0214
