Blasting Impacts Assessment for the Proposed GCC Rio Grande, Inc. Quarry in Pueblo County, Colorado <br />5.0 SUMMARY OF FINDINGS AND RECOMMENDATIONS <br />1. In order to prevent any possibility of significant ammonia or nitrate contamination of the <br />ground or water resources near the site, RAI recommends that blasting personnel should <br />have the proper tools to quickly and completely clean up any spilled explosive materials. If <br />bulk ANFO trucks are used to auger ANFO into boreholes, they should be fitted with <br />discharge hoses that can be lowered to the hole - collar to prevent wind losses of ANFO <br />fines. <br />2. To ensure effective charge confinement, blastholes should be stemmed with clean crushed <br />stone sized from 3/8 to 'h inches (9.5 to 13 mm). The height of stemming should b at least <br />10 charge diameters. For example, if the charge diameter is 6.5 inches (16.5 cm), at least <br />65 inches or 5.4 feet (1.6 m) of stemming should be used. <br />3. GCC Rio Grande should conduct a vibration study done for the purpose of developing site - <br />specific vibration attenuation characteristics. For ongoing compliance purposes, the <br />intensity of ground motion and air - overpressure generated by all subsequent blasts should <br />be measured at one or more locations between blast sites and structures of concern. <br />4. Based on the site - specific evaluations presented in this report, if the blasting operations at <br />the Red Rock site are conducted as indicated in the CGG permit application and further <br />controlled by the additional measures recommended above, it is extremely unlikely that <br />blasting of this type would cause any damage adjacent property, unduly disturb neighbors <br />and animals, or cause any harm to water resources, wells and buried pipes. <br />5. RAI also finds that there are no physical circumstances that would prevent the safe and <br />efficient operation of the proposed Red Rock limestone mining operation. <br />REVEY Associates, Inc.
