Rationale for Recommendation to Approve 31
<br /> September 29, 2016
<br /> In Exhibit 6.5,the application describes the geotechnical investigations that have occurred on the proposed
<br /> mine site. Norwest Corporation carried out a site investigation in 2015, where a total of seven boreholes
<br /> were advanced to depths of 200 feet to 800 feet below existing grades. Six of the boreholes were advanced
<br /> in the area north of Little Turkey Creek, and one borehole was advanced in the area south of Little Turkey
<br /> Creek. All boreholes were logged in the field by a Norwest geologist, collecting both geological and
<br /> geotechnical information. The logs of six additional boreholes, advanced by others during a previous site
<br /> investigation were made available to Norwest Corporation to aid in the geotechnical review. These
<br /> boreholes were advanced to shallower depths between 150 feet and 250 feet below existing grade, and
<br /> limited geotechnical information was collected. The investigation found that granite and granite
<br /> composites are more prevalent than any other major rock type within the proposed quarry and pit wall
<br /> locations. Approximately 81%of the rock encountered has been classified as granite or granite composite.
<br /> Detailed geophysical logs, drill hole lithology logs, and drill hole completion reports were included in
<br /> Exhibit 6.5.
<br /> In the Exhibit 6.5 portion of the adequacy review response submitted on July 14, 2016, the response to
<br /> item no. 19 confirms the Applicant recognizes that data is limited in the South Pit area. Information
<br /> gathered while mining the North Pit area will be evaluated and used to develop supplemental geotechnical
<br /> investigation for the South Pit.
<br /> As noted previously, the application includes a surface and groundwater monitoring plan sufficient to
<br /> verify the protection of surface and groundwater resources. The Division determined the permit
<br /> application satisfied the requirements of Rule 6.4.7, and the applicable performance standards of Rule 3.1.
<br /> 29. Concerns regarding the hazardous intersection of the proposed access road at Hwy 115 (too
<br /> close to Little Turkey Creek Road entrance off of Hwy 115; blind corner exists; should move access
<br /> road further south; is only a two-lane road here;proposed access point historically dangerous place)

<br /> The Act and Rules do not specifically address traffic safety. Such issues are under the jurisdiction of El
<br /> Paso County and the Colorado Department of Transportation (CDOT). These issues should be addressed
<br /> through the permitting processes of El Paso County and CDOT.
<br /> 30. Concerns regarding the Emergency Action Plan submitted - should commit to notifying the
<br /> Division within 24 hours of a failure or imminent failure of an impoundment, embankment, stockpile,
<br /> or slope,per Rule 8; Concerns that the mining operation will increase fire risk/danger - Emergency
<br /> Action Plan should include response to wildfires

<br /> Rule 8 —Emergency Notification by Operators, and Emergency Response Authority of the Office, is not
<br /> a required exhibit for a Construction Materials Permit application. This rule outlines emergency
<br /> notification procedures which are enforceable requirements for all approved permits. The Emergency
<br /> Action Plan submitted in Exhibit T is not a requirement for 112c permit applications.
