6.4.4(1) Explosives <br />Explosives will be used in accordance with the Blasting Report presented in the Geotechnical Exhibit <br />Section 6.5.4. Based on this assessment, blasting within the permit area can occur without structural <br />damage to adjacent manmade structures. Historically, underground blasting occurred on 2 by 2 foot <br />drill hole centers using maximum load of 200 pounds per blast. When surface blasting activities <br />were conducted, the drill hole spacing was approximately 6 by 6 foot spacing and no more than 200 <br />pounds of dynamite per blast. <br />Site blasting will be conducted by a third -party contractor. Explosives, blasting caps, etc. will not <br />be stored on site. Sunrise will conduct ground vibration monitoring on the first five blasts. <br />P. <br />
