EXHIBIT D MINING PLAN (cont) <br /> and west of the current clay pit, under the gravel, and will <br /> extend to the boundaries of the permit, less the required <br /> setbacks along the new ditch right-of-way. <br /> In the years of clay mining preceding 1976, the soil and <br /> overburden (sand and gravel) were stripped and stockpiled, <br /> generally unsegregated, on either side of the pit . These numerous <br /> piles have been mostly removed and processed for the rock they <br /> contain. As mining continues to progress, any remaining piles <br /> will also be removed and processed. The fines left over from this <br /> processing can be used as growth medium if additional soil is <br /> needed. Otherwise, the fines will be used for the construction of <br /> any compacted slopes . <br /> Since 1976, stripped materials have been segregated into <br /> soil and overburden before being stockpiled along the east, west <br /> and north sides of the permit area. Whenever possible, soil <br /> materials that have been encountered in the old waste piles have <br /> been saved and segregated into separate stockpiles along the <br /> perimeter setbacks. Soil and growth medium stockpiles have been <br /> planted with the same seed mixture as is used in reclamation <br /> revegetation in order to protect the soil from erosion and <br /> deterioration. <br /> There will be three types of material being removed from <br /> this mine, with each different mining operation having to work in <br /> harmony with the others. First, the sand and gravel is removed <br /> from over the clay and sandstone areas. This sand and gravel <br /> material is moved directly to the processing plant, as this saves <br /> from having to handle that material twice. The clay and sandstone <br /> are then mined once uncovered. The clay, sandstone, and aggregate <br /> operations are dependent on demand and will operate <br /> intermittently throughout the year, with long periods of <br /> inactivity punctuating periods of intense activity. <br /> Clay Mining <br /> The clay mining operation will continue as originally <br /> permitted. There will be no changes in mining methods in the clay <br /> area. After the area is stripped and once the sand and gravel has <br /> been mined, mining may begin from each of the four clay zones . <br /> The material is removed by dozer or excavator. It is then loaded <br /> onto a truck and hauled to the screening area on the south part <br /> of the permit area. Clay may also be screened and stockpiled to <br /> the east of the current clay pit . Other equipment used in the pit <br /> and stockpile areas includes, but is not limited to, a scraper, a <br /> front-end loader, various trucks, a Koleman screen, a grizzly, <br /> and water pumps . A clay processing area of approximately four <br /> acres has been established on the southwest side of the disturbed <br /> area. <br /> Lakewood Brick and Tile CO Church Pit— M-1979-045 <br /> Amendment 02 April 16, 2025 <br /> 11 <br />
