~. SAMPLE NUMBERS/SAMPLE ADEQUACY <br />For the purposes of this monitoring, set numbers of samples were established for the <br />parameters to be sampled by CDMG and Coors Energy Company. In the revegetated <br />area, ten cover transects were collected per reclamation year, and fifteen herbaceous <br />production quadrats were collected.per reclamation. year. In the Osgood Sand <br />Reference Area, ten cover transects were collected, and thirty (30) herbaceous <br />production quadrats were collected. <br />Since the purpose of this sampling is the monitoring of the vegetative condition at the <br />_ revegetated areas of the mine and Osgood Sand Reference Area, sampling was not <br />required to meet sample adequacy.
