• 2.05.6(6) <br />A table at the end of this section presents a listing of springs ponds and <br />water rights. The table presents the elevation of each feature and the <br />estimated depth each lies above the coal seam to be mined. Generally no <br />subsidence protection will be provided for springs unless they are a decreed <br />water right and only then if the spring has an overburden depth of less than <br />800 feet. Most of the springs and ponds within the permit boundary and <br />adjacent area have overburden depths which exceed 800 feet. <br />A limited extraction zone as referenced below is defined as an area in which, <br />if mined, will be limited to first mining only with no pillar slabbing. The <br />proposed location of the limited extraction zones are presented on Map 27, <br />Subsidence and Maps 14 & 14B, Mine Plans. <br />Pond P-1 is located in a zone of greatest subsidence impact. For this <br />reason, this pond will be protected by a limited extraction zone. The limited <br />extraction zone is defined by extending a safety zone a distance of fifty feet <br />around the pond and then projecting a line down at the angle of draw until it <br />• intersects the coal seams. <br />Pond P-2 is located in a zone of intermediate subsidence, however the <br />overburden below P-2 is nearly 1,000 feet. For all practicable purposes P-2 <br />is in a zone of minor subsidence. Therefore, no limited extraction zone will <br />be provided for Pond P-2. <br />Ponds P-3 through P-6 are located in a zone of minor subsidence in an area <br />of overburden greater than 1,000 feet. Therefore, no limited extraction zone <br />will be provided for Ponds P-3, P-4, P-5 and P-6. <br />Five additional ponds are located within the permit boundary in zones of <br />minor subsidence. They are Pond 33-3, Spriny/Pond 33-5, Pond 33-7, <br />Spring/Pond 34-2 and Spring/Pond 34-11. Two ponds are located outside <br />of the permit boundary in zones of minor subsidence. They are Pond 32-3 <br />and Spring/Pond 33-6. Refer to Map 9, Hydrologic Location Map for location <br />information. <br /> <br />TR-031 <br />2.05 - 107 - 02/04 <br />/~l PPR o vED <br />s/„boy <br />
