F^'=.e:~rcc~ <br />December 30, 1981 <br />Mr. Richard Domingue <br />Mined Land Reclamation Division <br />423 Centennial Building <br />1313 Sherman <br />Denver, Colorado 80203 <br />Dear Mr. Domingue: <br />By this letter Wyoming Fuel Company is complying with Stipulation <br />#20 of Wyoming Fuel Company's Canadian Strip Mine Permit. <br />The stipulation reads as follows: <br />"Wyoming Fuel Company shall develop a biennial revegetation <br />success program and submit it to the Division for review and <br />approval by December 31, 1981." <br />The overall objective in evaluation of Wyoming Fuel Company's <br />revegetation program is to insure on a regular basis that we are <br />meeting premining vegetative standards. This regular evaluation <br />will provide Wyoming Fuel Company with information which can be <br />used to modify our reclamation approach as necessary. <br />The primary vegetative characteristics of interest for this <br />evaluation will be vegetative cover and species composition. Since <br />reclamation is conducted in phases it will be necessary to evaluate <br />each phase individually. For this reason, we are proposing to <br />establish ten (10) permanent baselines located in each reclamation <br />phase. These baselines will be randomly located. Steel posts will <br />be established at the beginning end point of each baseline. Trans- <br />ects for estimating vegetative characteristics will be randomly <br />located and run perpendicular to each of these baselines. The number <br />of transects run during an evaluation period will depend upon the <br />statistical confidence desired. <br />At this time it is anticipated that these permanent baselines <br />will also be used in evaluation of revegetation success for bond <br />release. This procedure will allow us to evaluate revegetation over <br />a period of years rather than relying on a one time sampling effort. <br />
