23 ROW Alternative Energy CDOT Alternative ROW Source Giga-Watt Hours/Year- Solar 554,700/55,500 (10% efficiency) Wind 380 Biomass 5 Geothermal 8530 acres Hydropower Very limited Colorado 2007 Energy Demand 5,547,000 GWh/year

24 Potential Impacts of Solar Arrays On Highway Safety and Operations Leasing land to energy developer Solar array generated energy Interstates 76 and 70 model locations Identify impacts and mitigation strategies Safety Environmental Operation and Maintenance Guidance document

26 R&D Approach Task 1- Literature review/communication Task 2- Impact and risk identification Task 3- Solar array design and criteria Task 4- Report development/presentation

27 Low Risk Elements Environmental Wildlife attraction Bird migration NEPA process Hazardous waste Safety Natural hazards (steep slopes/floodplains) Driver awareness Traffic controls Security fencing Operation/Maintenance Mowing alterations

28 Medium Risk Elements Environmental General wildlife habitat impact Prairie dog colonies Noxious weeds Safety Glint/glare Working in the ROW Solar array framework integrity Solar array access Operation/Maintenance Snow blowing/plowing

29 Higher Risk Elements Environmental Stormwater management/revegetation T&E habitat Community acceptance Safety Immovable structure Traffic controls Security fencing Operation/Maintenance Snow drifting and deposition Magnesium chloride

30 Environmental Permitting Considerations Coordinate with CDOT Regions for NEPA requirements (Categorical Exclusion) Stormwater Management Plan and Construction Stormwater Permit (greater that one acre) Phase I and Phase II Hazardous Waste Assessment Permanent Stormwater Best Management Local government permitting identified Public outreach and education

31 Siting Criteria Elements Site, utility and road access available to project for duration of use/agreement 3-phase power or capability At least 95% total solar resource fraction Fiber optic connectivity for security and data transmission Project must be in CDOT owned right of way Array system within the clear zone area at least 30 feet from edge of travel lane Project area not within or adjacent to threatened and endangered species flora or fauna

32 Siting Criteria Elements Project site at least 5 acres Project area has 24/7 year round access Project Area within 1/2 mile of existing electricity grid Project site has less that 5% slope Project site has southern exposure Project site not within designated floodplains, wetland area or protected stream corridors Project area not within or adjacent to threatened and endangered species flora or fauna Reference- Oregon Solar Highway

33 Areas of Study Snow drifting and deposition Snow fencing models Glare and glint Safety mitigation measures in Clear Zone Breakaway design for array framework Guardrail placement Protective berms Maximize distance from roadway Magnesium chloride
