Climax Molybdenum Company <br /> Permit No.1977-342 Technical Revision JR-35) <br /> 3. OTHER AGENCY PERMITS AND AUTHORIZATIONS <br /> The state and local permits and approvals that will be required from agencies other than the DRMS specifically <br /> for the WTP are described below. No federal permits or approvals have been identified as required for the WTP. <br /> 3.1 Air Permit <br /> Henderson holds an active Air Permit (#02GR0546.CP5) issued by the Air Pollution Control Division (APCD) of <br /> the Colorado Department of Public Health and Environment (CDPHE). The lime silo and emergency generators <br /> to be located at the WTP represent the only identified sources associated with this project that may have regulated <br /> air emissions. The lime silo emissions are anticipated to be permit exempt. As detailed specifications for the <br /> emergency generator are developed, permitting requirements will be determined and a modification request will <br /> be submitted to the APCD, if necessary. Dust control measures during construction will be employed to minimize <br /> the generation of dust and maintain compliance with the opacity limits in the air permit. <br /> 3.2 Grand County Activity of State Interest <br /> The WTP falls under the classification of Municipal and Industrial Water Projects under the Grand County <br /> Administrative Regulations for Areas and Activities Designated as Matters of State Interest. Henderson is in the <br /> process of obtaining what is known as a 1041 permit through the County Planning Department. <br /> 3.3 Grand County Building Permits <br /> The Building Permit will be submitted to Grand County following substantial completion of the design. The Building <br /> Permit application will include the following information: <br /> Building Permit application form <br /> General drawings including: Cover sheet, plot/site plan (showing property lines, setbacks, structures, <br /> topography, driveway, water features, sanitation features) <br /> Building plans (foundation plan, floor plans, roof plans, exterior elevations, details, building sections) <br /> Structural plans (foundation Plan, foundation details, floor framing plans, roof framing plan, structural <br /> details) <br /> Additional information which may be requested i.e., ceiling plans, lighting and power plans, <br /> mechanical equipment plans, landscaping plans, interior finish details etc. <br /> The building permit also requires the following: <br /> Proof of Legal Sanitation - OWTS Application (Septic permit) <br /> Proof of Legal Drinking Water <br /> Proof of Fire Impact Fee <br /> Contractor Verification Form or Acknowledgement of Contractor Insurance <br /> 3.4 Grand County Septic Permit <br /> An application for an onsite septic system permit will be submitted to Grand County for the WTP prior to <br /> construction of the system.

This system will provide potable water at an <br /> approximate average rate of 2.8 gpm and will include a 1,000 gallon storage tank and small bladder tank for <br /> April 2022 <br />
