RECOMMENDED PRACTICES AND CONTROLS <br />For BLASTING OPERATIONS at <br />SUMMIT $RICKAND TILE CO.'S <br />CLAY MINES <br />CONCLUSIONS and SUMMARY <br />The following general summary of findings, which considers the impacts of the proposed <br />blasting and excavating work of Summit Brick and Tile Co. (Summit Brick) are reviewed <br />by Albuquerque Geological (AG). Conclusions and specific recommendations for <br />controlling specific aspects of the blasting and excavating work are included in sections of <br />this report addressing each individual mine owned and operated by Summit Brick. <br />1. After a careful review all of the potential impacts that blasting might have at the 1.J <br />Fox, 2.f forks, 3.) 8-Mile Clay, 4.) Beaver Greek, 5.J anon, 6.) Cedaswood, <br />and 7.J Edmundson mines on the local population; their dwellings, animals, structures <br />or buildings, water wells, and the environment in general, A G has found no cause or effect <br />that would prevent the proposed blasting and mining from being safely performed. In <br />order to make this determination, A G has used published blasting and engineering data, <br />as well as our experience directly involved in many projects where rock blasting was <br />performed without incident. Each mine was visited to determine site specific conditions <br />and requirements. <br />2. AG has found no evidence-suggesting that blasting and rock excavation-will have <br />any significant tong term impacts on the land that will be mined within Summit Brick's <br />.various permitted :mining -areas.-.Noise -and - vibration--from-blasting would exist only <br />temporarily during each event and they are not expected to cause any lasting damage. <br />The effect or impact on groundwater would be negligible, as the blasting is taking place at <br />the surface and the depth of groundwater in all cases is significantly below this level. <br />A site-specific plan has been made for each i~ividual min site and is shown above. There <br />maybe be slight variations to the information included within this report, however, in all <br />circumstances, all conditions stated here-in are to be considered a maximtun conditions or <br />amounts ofpowder used. <br />4 <br />
