Location and Number of Acres Affected During the YeaxC010. ~epl. Of Pti32~:tal I~E60UrC3~ <br />Refer to the attached map illustrating the affected areas. <br />A summary of the affected areas to date is given as follows: <br />Additional Area Disturbed the Past Year: 0.25 ac. <br />Approximate Area Disturbed to Date: 9 ac. <br />2. Location and Number of Acres Reclaimed the Past Year <br />Most of the disturbed area remains active. No reclamation took <br />place during the past year. <br />3. Location and Number of Acres in the Various Stages of Reclamation <br />Due to a reduction in the demand for brick the past several years, <br />the rate of mining has been somewhat less than originally <br />anticipated. The attached map portrays the areas disturbed to <br />date. The mining plan involves the removal of a knoll, mined in <br />a southerly direction. Backfilling of overburden is not involved <br />in this operation because a pit is not created. <br />4. Location of Species and Vegetation Planted <br />No revegetation has occurred to date because most of the disturbed <br />area is used for various purposes (stockpiling, overburden placement, <br />and mining). However, some natural invasion of grasses has occurred <br />on the northeast portion of the overburden dump where calcined-clay <br />overburden was deposited a few years ago. <br />5. Types and Quantity of Fertilizer Used <br />Not applicable at the present time. <br />6. Appraisal of Reclamation Efforts <br />Not applicable at the present time. <br />7. Estimate of the Area to be Affected in the Coming Year <br />For the most part, it is anticipated that operations will be <br />confined to the existing disturbed area as illustrated on the <br />attached map. <br />
