Mining and Safety <br />Priola Pit - M-2007-087 <br />Adequacy Review O1' <br />On behalf of my client Albert Frei and Soris, Inc., I will respond <br />to your adequacy review; in the order presented. We have continued the <br />decision date to June 1~,2, 2008 per our. discussion for time to. resolve <br />some of the items in your letter. <br />Rule 3.1.5 Reclamation Measures - Materials handlin_g <br />,Find attached the inert';filT affidavit ,for this mine. The backfll <br />material to be placed in the excavated area will be~ "Inert Material" <br />a as defined in Rule 1.1020). The. material placed from 2 .feet above. the <br />water line to the bottom of the excavated area will be a mixture of <br />crusher fines; and dirt mixed with minor amounts of aged concrete <br />fragments. This material.has no uni"que characteristics that would <br />cause it to have an imp'.;act on groundwater. Crusher fines are fine <br />materials-left from processing quarry rock we generate at another of <br />our mi"nes. Above this ',the fill material will be aged concrete, dirt,. <br />crusher fines, masonry products and asphalt. Any asphalt that is <br />delivered will be reserved and placed above the water line. <br />Rule 3.1.6 Water - General +'!Requirements ~ " <br />', -- <br />1_) .The well"in question is, 12 feet deep while the others are in <br />access- of .300 feet. deep. There is no "communication" between the <br />aquifers 'for these deep well. The reason we stated the shallow <br />well would be removed is it lies within the mined area and will <br />be easier to removed than mine around. The"landowners' may choose <br />to replace this well once filling is complete or abandon it. <br />Thank you for the',~information on abandonment, we will advise them <br />of your concerns and~let them make the decision on that issue <br />when. the time comes. ~ - <br />2) No dewatering is planned for- this mine. As noted on page 10 of <br />the application, the water table lies 6 to 10 feet below the <br />surface. In Exhibit L we explained that 9 feet of fill would be <br />needed to fill"the below water area to ari elevation that is 2 <br />~. <br />
