At the completion of mining operations, the New Access Road will be reclaimed and the area impacted by its construction will be returned to the natural topography. One exception to this will be the "cut- through" section of road. The reclamation grading in this area will maintain a maximum slope of 2:1 versus a historical slope of approximately 1.5:1. After reclamation grading has been completed, the disturbed areas will be planted with seed summarized in the approved mine permit and steep slopes will be protected with erosion control blankets to prevent erosion while the seed is establishing. Details of the reclamation work can be found in the Construction Drawings included in Appendix A. CONSTRUCTION IMPLEMENTATION PLAN This section includes a general description of the construction implementation for the New Access Road, discussion of the construction documentation and reporting procedures, the construction II quality control and assurance guidelines and the project closeout and final construction completion report. Construction implementation is anticipated to begin in June 2012. The roadway design will need to be approved by La Plata County and a variance will also need to be approved for the section of road for which the grade exceeds the County's standard of 12 %. Construction will begin with installation of necessary runoff and erosion BMP controls shown on the construction drawings. Initial work will also include installation of any necessary safety features and other controls required by MSHA or DRMS. Grading operations will begin after inspection of BMPs and verification that they are installed correctly has been completed. 1 Documentation and Construction Reporting A pre- construction meeting will be held with the construction contractor, owner and engineer prior to the start of any work on the New Access Road. This pre- construction meeting will cover topics such as roles and responsibilities, communication, health and safety, procedures for field and design changes during construction and schedule. Minutes of the pre- construction meeting will be issued to attendees within three work days following the meeting. During construction daily reports generated by the contractor will be reviewed by the field inspection technician and engineer of record. The technician will prepare regular construction quality assurance (CQA) reports describing his/her observations and actions taken to correct deficiencies in the work. Field test results and the contractor's reports will be included as attachments. The technician's CQA reports will be forwarded to the geotechnical engineer for review and action (if any is required). The geotechnical engineer will transmit weekly status reports to Mr. Dustin Czapla, DRMS, containing a brief summary of the work, including actions taken, outstanding issues to be resolved if any, and planned activities for the upcoming week. Quality Assurance and Control (QA/QC) Guidelines Wildcat will comply with the requirements described in the following QA/QC guidelines. Its purpose is to assure that construction is completed per the Construction Drawings and the Rule 6.5 Geotechnical Stability Report. Definitions • Quality Control — A mechanism performed by the contractor for ensuring that construction activities conform to the construction drawings and specification; • Quality Assurance — A mechanism performed by the Owner to ensure that construction activities conform to the construction drawings and specifications; • Regulatory Authority — Division of Reclamation, Mining and Safety and /or La Plata County; Page 5
