The Denver Brick Company MLRB Annual Report - 1988 Dawson Mine, File: M-77-392 Permit Anniversary Date: March 11 1. Location and Number of Acres Affected During the Year Refer to the attached map illustrating the affected areas. A summary of the affected areas to date is given as follows: Additional Area Disturbed the Past Year: 0.3± ac. Estimated Area Disturbed to Date: 9.9t ac. 2. Location and Number of Acres Reclaimed the Past Year Most of the disturbed area remains active. No reclamation took place during the past year. 3. Location and Number of Acres in the Various Stages of Reclamation The attached map portrays the areas disturbed to date. The mining plan involves the removal of a knoll, mined in a southerly direction. The rate of mining remains low, with only an estimated 10,000 to 12,000± tons removed from the site the previous year. Backfilling of overburden is not involved in this operation because a pit is not created. 4. Location of Species and Vegetation Planted No revegetation has occurred to date because most of the disturbed area is used for various purposes (stockpiling, overburden placement, and mining). However, some natural invasion of grasses has occurred on the northeast portion of the overburden dump where calcined-clay overburden was deposited a few years ago. 5. Types and Quantity of Fertilizer Used Not applicable at the present time. 6. Appraisal of Reclamation Efforts Not applicable at the present time. 7. Estimate of the Area to be Affected in the Coming Year For the most part, it is anticipated that operations will be confined to the existing disturbed area as illustrated on the attached map. For the coming year, it is anticipated that only a relatively small volume of material will be mined from the site -- similar to the amount removed the previous year.
