WORWEST <br /> COR PORAT ION <br /> To: Colorado Division of Reclamation, Mining, and Safety Ref# 591-6 <br /> CC: Jerald Schnabel,Transit Mix Date: October 3, 2017 <br /> From: Paul Kos <br /> Subject: Engineering Evaluation of Overhead Electric Distribution Lines <br /> Introduction <br /> Three segments of overhead electric distribution lines are existing structures located within 200 feet of <br /> the proposed Hitch Rack Ranch Quarry permit boundary. These locations are shown on Figure 1. This <br /> engineering evaluation discusses the structure locations and components before evaluating potential <br /> impacts quarry development could have on the structure and presenting what measures will be taken so <br /> that there is no adverse impact to the structure. <br /> Structure Description <br /> Overhead electric distribution lines exist within 200 feet of the proposed Hitch Rack Ranch Quarry <br /> permit boundary. These power lines are located along Highway 115 and along the access road, and <br /> none are located in the mining areas. The power line along Highway 115 includes a branch line that runs <br /> to Fort Carson, and this line is owned by Colorado Springs Utilities. The power line inside the Hitch Rack <br /> Ranch (RMBC Group, Inc.) property is owned by Black Hills Energy. Each overhead electric distribution <br /> line consists of elevated cables that transmit electricity. All of the powerlines are single phase lines that <br /> provide residential or local service. None are regional or triple phase transmission lines. <br /> Potential Impacts and Mitigation <br /> Potential Problem: Construction of the access road could damage the overhead electric distribution <br /> lines. <br /> Solution: Construction crews routinely work around utilities and have standard operating procedures <br /> for not impacting or damaging the utility lines. Activities and equipment with the highest risk of <br /> impacting a power line include those with potentially elevated components such as: cranes, drill rigs, <br /> excavators, and dump trucks. These procedures typically include signage on each side of the power line <br /> to remind operators of the hazard and using spotters if work is required near the power lines. Federal <br /> law requires at least 10 feet of clearance for voltages under 115,000-the higher voltage the greater the <br /> distance. Transit Mix will ensure that these practices are followed when working near utility lines. <br /> Hitch Rack Ranch Quarry Amendment Exhibit T <br /> October 3, 2017 <br /> S-8 <br />
