If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. 1. Explain, in detail, the proposed use of the property. The solar array project will deliver energy to United Power under a 20-year power purchase agreement (PPA) and must commence commercial operation no later than December 31, 2015. The project is designed for un-manned operation except for bi-annual inspections and routine maintenance. As such, this facility will not represent any traffic impact to the Town of Mead or the region following the construction phase. The solar array will be located on a parcel of land that is 214 acres in size, and the footprint of the solar array will comprise of approximately 45 acres of land . Of this 45 acres, approximately 401 of that area will remain open space. The solar modules will be mounted on single-axis tracking structures, which are designed to follow the sun's E-W path throughout the day. The modules will be mounted approximately five feet above grade with four (4) inverter stations positioned within the array field interior to the project site, these inverters stand approximately 12' in height and the solar array panel will be a maximum of 8' above grade with the modules at full-tilt. No significant visual impact are anticipated to adjacent or nearby properties or roadways. As part of Silicon Ranch's standard operation procedures, and upon the termination of the PPA, the solar arrays will be dismantled and the land will be restored to historic conditions. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. Section 22-4-40 of the Weld County Code describes allowing development that encourage clean air and emissions of hazardous pollutants. This development uses solar power and converts it to electrical power. This development will not discharge any air emissions into the atmosphere. Section 22-4-60 of the Weld County Code describes how noise shall be considered . This development will not generate any perceivable noise and therefore complies with this development requirement. Section 22-5-110 and NR Goal 5 of the Weld County Code describes that other natural resources shall be utilized . The proposed solar array is a renewable natural resources that would be supportable. Section 22-4-140 and section 22-4-160 of the Weld County Code specifically encourages large scale solar collection for energy support facilities. Sec. 22-4-40. Air.

(Weld County Code Ordinance 2008-13) 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. Sec. 23-3-40. Uses by special review D. Public Utilities facility, including: 3. MAJOR FACILITIES OF PUBLIC UTILITIES OR PUBLIC AGENCIES, subject to the provisions of Section 23-4-420. Sec. 23-4-420. Public utilities facilities. Applicants for activities reviewed pursuant to Article II, Division 5 of this Chapter as MAJOR FACILITIES OF PUBLIC UTILITIES shall have the burden of proof to demonstrate that there is a need for the facility within the proposed area of service, and the Planning Commission shall be satisfied that a need exists as part of the determinations for any such permit. 4. What type of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). The property surrounding this site is a mix of agricultural, Oil/Gas infrastructure, irrigation center pivots, and Weld County Road 34. As described above, this site is fully contained and will not hinder the production, or landscape, of its neighbors. 5. Describe, in detail, the following: a. Number of people who will use this site This site will be un-manned. b. Number of employees proposed to be employed at this site During construction it is anticipated that there will be a maximum of 25 employees and contractors on the site. Post construction the facility will be un-manned. c. Hours of operation 24/7, 365 days a year. Silicon Ranch has a Power Purchase Agreement with United Power for a 20 year Power Purchase Agreement ( PPA) . After the term of the contract has S 1 - expired then there is an option to extend the agreement on a yearly basis until the contract is terminated . Upon termination, the solar array will be dismantled and the site reclaimed and returned to historic conditions. d. Type and number of structures to be erected (built) on this site No structures are proposed with this development. The Solar array will be un-manned and therefore no buildings are needed . There will be one (1) sea-can brought onsite to store maintenance material and basic repair parts. The sea-can will be enclosed to provide security and protection to the stored material from the natural elements. e. Type and number of animals, if any, to be on this site No animals will be on this site. f. Kind of vehicles (type, size, weight) that will access this site and how often During construction, semi-trucks and trailers will be used to bring the material onsite. It is expected that construction will last a maximum of 3 months. Once construction is completed then a light duty maintenance truck or rental car will visit the site bi-annually to inspect the site and perform general maintenance. If major repairs are needed then it may be necessary to bring in a larger maintenance truck to perform the needed repair. Major repairs are not anticipated to occur on a regular basis. g. Who will provide fire protection to the site Mountain View Fire Protection District h. Water source on the property (both domestic and irrigation) Since this an un-manned facility, a domestic water tap is not needed with this development. Low growing, dry land grass will be planted and water will be hauled in as needed from a local water service provider or other means available. Once the dryland grass is established then there will not be a need for irrigation. During construction water will be hauled in by a local water service provider to control dust and erosion . I. Sewage disposal system on the property (existing and proposed) Port-A-Potty during will be provided during construction. Once constructed, this will be a un-manned facility and therefore a sanitary sewer tap is not needed with this development. j. If storage or warehousing is proposed, what type of items will be stored It is proposed to keep on-site basic repair materials and general maintenance items. All items will be contained an enclosed sea-can and will be locked. No oils or hydrocarbons S s. — — — will be stored in large quantities. If hydrocarbons are stored in the sea-can then they will be stored in the manufactures provided containers and in quantities less than 5 gallons. 6. Explain the proposed landscaping for the site. The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. Landscaping will be low growing, native dry land grasses. Grass will be mowed on a needed basis and a minimum of 2 times a year. Landscaping will be minimal and will be keep in a clean manicured condition . 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Upon the termination of the Power Purchase Agreement (PPA), Silicon Ranch will remove all improvements and either recycle, reuse, or repurpose the materials. The contours of the land will be smoothed and any disturbed land will be reseeded with a native dryland seed mixture and allowed to establish to historic conditions. 8. Explain how the storm water drainage will be handled on the site. Stormwater will be conveyed to a water quality pond and then discharged in historic discharge areas. Water quality pond is designed in accordance to Weld County standards and requirements, see included drainage letter provided with the USR submittal . Stormwater will be discharged to the Supply Ditch . 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. The construction of the site is scheduled to begin the first week in July, 2015. The construction schedule will last approximately 3 months after mobilization . Per the Power Purchase Agreement this facility MUST be operational by December 31, 2015. Silicon Ranch will submit for an early grading and building permit so that construction can begin as soon as possible to meet the strict deadlines of the project. Construction of the solar array will begin as soon as all permit approvals are in place. It is anticipated that construction will take 3 to complete. 10. Explain where storage and/or stockpile of wastes will occur on this site. During construction all trash generated will be placed in an approved trash or recyclable receptacle and will be hauled away and properly disposed . Once construction id completed, all trash generated during a site visit will be removed from the site on that visit. Since this is an un-manned facility, there is no need for regular trash service. There will be no storage or stock piling of wastes onsite. t ins /i • • 11. Please list all proposed on-site and off-site improvements associated with the use (example: landscaping, fencing, drainage, turn lanes, etc.) and a timeline of when you will have each one of the improvements completed. All improvements will be completed in a single phase that will last approximately 3 months. Many of the improvements will be constructed concurrently. Proposed improvements include the following and in the general order as following: o Stormwater BMP's o Access road to access the solar array. o Inverter for solar array, see site plan . o Solar Array, see site plan . o 6' Black Vinyl coated chain link fence. o Disturbed areas shall be seeded with low grow, dry land seed mix. Since this development will not generate an increase in traffic, there are no public roadway improvements with this development. 1 • WASTE HANDLING PLAN SILICON RNCH SOLAR ARRAY FACILITY WELD COUNTY, COLORADO Silicon Ranch has detailed policies and procedures in place that will be applied to the specifics of any waste generated and disposal from the facility. If present, any waste will be disposed of in accordance to the governing jurisdiction . Solid Waste Solid waste will not be generated by the daily operations of the facility. If solid waste is observed or generated then it will be collected and removed by the personal visiting the site. Disposal of collected solid waste will be removed from the site on each visit and properly disposed . No trash receptacles or trash hauling service will be provided at this facility. Chemicals It is not anticipated that any chemicals, lubricants or solvents will be stored at on the proposed facility, however if chemicals, lubricants or solvents are stored on-site then they will be stored in an enclosed structure where it protected from the natural elements and in accordance with the manufactures recommendations. Any stored chemicals, lubricants or solvents will be less than 5 gallons in size. It is anticipated that any chemicals, lubricants or solvents to be used on-site will be brought in by the maintenance personal . If necessary, disposal of chemicals, lubricants and solvents will be completed according to the manufacturer and state requirements. Hazardous Waste No hazardous waste will be generated , stored or used on-site. Leaving a Legacy of Enduring Improvements to Our Communities - PURPOSE STATEMENT ENGINEERS SURVEYORS PLANNERS ft DUST ABATEMENT PLAN SILICON RANCH SOLAR ARRAY FACILITY WELD COUNTY, COLORADO Throughout the life of this project, Silicon Ranch will utilize on-site vegetation and other best management practices to control fugitive dust from being generated and transported offsite . During construction (0 to 3 months) Silicon Ranch contractors will utilize water trucks as needed to control fugitive dust from any disturbed areas and from the access road . Vehicle speeds will be limited to ten miles per hour or less to reduce dust being generated by vehicles accessing the site. To minimize water usage, the site contractor may treat the access roads with approved dust suppression or dust abatement products. Water used for dust suppression during the construction phase will be provided by a local water provider as selected by the site contractor. It is expected that the construction phase will last 3 months. Post construction (3 months to 20+ years) Silicon Ranch will seed any disturbed areas with a native dryland seed mix and will nurture until the vegetation is considered established , thereby reducing fugitive dust in the ultimate condition . Once the solar array is constructed , it is anticipated that maintenance trucks will only visit the site on a bi-annual basis to inspect the site or to perform facility maintenance and repair. Daily traffic will not be generated by this development. If it is found that additional dust mitigation is needed , then Silicon Ranch will treat with approved dust abatement products. If any vegetated areas are disturbed during facility maintenance activities, these disturbances will be re-vegetated as soon as practical , but in no case longer than 3 months shall pass . Once construction is completed , water used for dust suppression and for the establishment of the landscaping will be provided by contracting with a local water provider.

More specifically the project is located on Lot D of Recorded Exemption RECX13-0049 which is approximately 214 acres in size and situated approximately 0.8 miles west of the intersection of Weld County Road (WCR) 5 and WCR 34. The site is roughly 1 .7 miles west of Mead, Colorado. General Description of Project It is proposed to utilize approximately 45 acres of the 214 acres for the solar array project. The solar array will deliver renewable energy to United Power under a 20-year power purchase agreement (PPA). Upon termination of the PPA, the solar panels will be removed and the land restored to historic conditions. Drainage Design . Of the 45 acres being developed, approximately 40% of that area will remain open space and vegetation will be allowed to grow underneath the solar panels, therefore it has been calculated that very little imperviousness is added to the site from the proposed improvements, therefore a waiver is requested to only provide a water quality pond to treat runoff from the solar array project. Two water quality ponds will be constructed within the proposed drainage swale areas that are located along the south side of the solar arrays. Storm water will surface flow in historic routing to the proposed drainage swales and to the water quality ponds. Collected stormwater will be discharged into the existing Supply Ditch and the Highland Ditch. Evaluation of water quality capacity was done by employing the Weld County sizing requirements. See Use By Special Review (USR) planning documents for the location of the proposed drainage swales and water quality ponds and the attached calculations for water quality sizing. Sediment and Erosion Control During construction, land grading activates will be minimized to allow for the installation of the solar arrays and BMP's will be installed where needed to minimize the offsite transport of sediment. Once the project is completed then any disturbed areas will be reseeded with a native low growth dryland Leaving a Legacy of Enduring Improvements to Our Communities - PURPOSE STATEMENT ENGINEERS SURVEYORS PLANNERS seed mix. Once vegetation is considered established, then BMP's will be removed. The established vegetation will provide permanent sediment and erosion control for the site. If it is found that additional erosion control measures are needed after the site has been completed, then additional erosion and sediment control practices will be implemented . Conclusions Overall storm water runoff will be allowed to sheet flow generally consistent with historic conditions and patterns, with the additional benefit of water quality ponds. The water quality ponds will enhance any storm water being conveyed offsite and to the Supply Ditch or the Highland Ditch. Overall the proposed site improvements will generally result in no significant change to peak runoff rates or volume. This development will not cause additional health or safety risks to neighboring properties. If you have any questions or concerns, please feel free to contact us at your convenience.

More specifically the project is located on Lot D of Recorded Exemption RECX13-0049 which is approximately 214 acres in size and situated approximately 0.8 miles west of the intersection of Weld County Road (WCR) 5 and WCR 34. The site is roughly 1 .7 miles west of Mead, Colorado. General Description of Project It is proposed to utilize approximately 45 acres of the 214 acres for the solar array project. The solar array will deliver renewable energy to United Power under a 20-year power purchase agreement (PPA). Upon termination of the PPA, the solar panels will be removed and the land restored to historic conditions. Drainage Design . Of the 45 acres being developed, approximately 40% of that area will remain open space and vegetation will be allowed to grow underneath the solar panels, therefore it has been calculated that very little imperviousness is added to the site from the proposed improvements, therefore a waiver is requested to only provide a water quality pond to treat runoff from the solar array project. Two water quality ponds will be constructed within the proposed drainage swale areas that are located along the south side of the solar arrays. Storm water will surface flow in historic routing to the proposed drainage swales and to the water quality ponds. Collected stormwater will be discharged into the existing Supply Ditch and the Highland Ditch. Evaluation of water quality capacity was done by employing the Weld County sizing requirements. See Use By Special Review (USR) planning documents for the location of the proposed drainage swales and water quality ponds and the attached calculations for water quality sizing. Sediment and Erosion Control During construction, land grading activates will be minimized to allow for the installation of the solar arrays and BMP's will be installed where needed to minimize the offsite transport of sediment. Once the project is completed then any disturbed areas will be reseeded with a native low growth dryland Leaving a Legacy of Enduring Improvements to Our Communities - PURPOSE STATEMENT ENGINEERS SURVEYORS PLANNERS seed mix. Once vegetation is considered established, then BMP's will be removed. The established vegetation will provide permanent sediment and erosion control for the site. If it is found that additional erosion control measures are needed after the site has been completed, then additional erosion and sediment control practices will be implemented . Conclusions Overall storm water runoff will be allowed to sheet flow generally consistent with historic conditions and patterns, with the additional benefit of water quality ponds. The water quality ponds will enhance any storm water being conveyed offsite and to the Supply Ditch or the Highland Ditch. Overall the proposed site improvements will generally result in no significant change to peak runoff rates or volume. This development will not cause additional health or safety risks to neighboring properties. If you have any questions or concerns, please feel free to contact us at your convenience.

The proposed development is located in the northwest 1 /4 of Section 17, Township 3 north , Range 68 west. More specifically the project site is approximately 214 acres of land and is located approximately 0.8 miles west of the intersection of Weld County Road 5 and Weld County Road 34 . The site is roughly 1 .7 miles west of Mead on the south side of Weld County Road 34. The facility proposed as a photovoltaic solar facility that will provide electrical power to United Power electric grid system . Electrical power generated by this facility will provide a renewable energy resource for the United Energy portfolio.

U fPP5Ufl SO - • R INVERTER W LL_ Power Electronics ' Freesun HEC and HEC + rd generation of outdoor modular and redundant inverters are the most powerful and reliable air cooled Utility Scale PV Inverters in the market . 1000Vdc class upgraded inverters offer extended MPPt voltage range and maximum eff biency in three different AC output voltages 360 Vac , 380 Vac and 400Vac , covering all commercial and utility - scale PV facilities. �. Freesun HEC and HEC + are based on a modular & redundant topology with up to 10 modules ranging from 150 kVA to 170 kVA that provides the competiveness of central inverters and the availability of string inverters . The Freesun HEC and HEC+ are featured with an outdoor IP54 stainless steel enclosure , 50mm rockwool isolation panel and the most advance iCOOL filter- less system that makes it suitable for the most demanding conditions. Freesun HEC can be equipped with customized internal ( HEC+ ) or external DC disconnection and protection subsystem that makes it compatible with any PV plant configuration and the highest DC :AC ratios .

It is constructed with independent modules from 150 to 170kVA , each module includes its own control board , power stage and cooling system , being coupled by the DC and AC buses. In the end , an issue only affects to one of the units and never the entire system . At the same time, the power of the faulty module is sent to an adjoining operative module, so that it only reduces the injected power when the maximum rated power is reached . If not , you won 't lose a kWh and you might probably never realize that a module is not operative. All the units work in parallel together commanded by the master. This master is the main governor of the system and is responsible of the MPPt tracking , synchronization sequence, overall protection . . . Freesun HEC is smartly designed to last . The automatic mode shifts every night the master role by comparing the register of energy production of every module. The one with less energy produced ( kWh) will act as a master next early morning with the first sunbeams. This feature enables a homogeneous wear and tear of all the components in the modules, extends the product lifetime and MTBF ratio .

TT FREESUN SOLAR INVERTER / POWER ELECTRONICS When addressing the selection of a solar inverter manufacturer, there are crucial points that should be considered first and inverter's eff biency is one of the most important . On low radiation conditions, a modular inverter operates at higher eff biency levels than a similarly sized central inverter. By shutting off unneeded power modules, modules load increases to get the maximum available eff biency. At the same time, a lower power rating of the inverter units allow to start feed -in earlier in the morning and to stop later in the afternoon . As a result , throughout the entire service life of the PV plant , HEC will generate higher yields than central or string inverters.

Our know how in mining , water treatment plants, CSP facilities in the most demanding locations all over the world have given us the necessary experience to develop the perfect technical solution for our outdoor solar inverters. Freesun HEC modules are divided into two main areas: clean area (electronics) and hot area (filters and heat sink) . The electronics are totally sealed and use a temperature control low flow cooling system that reduces filters clogging and maintenance intervals. The hot area integrates independent and speed controlled fans per each module, reducing to the maximum the Stand -by consumption at low capacity and boosting the cooling capacity for PV installation situated at higher altitudes than 3000 meters above sea level. a a r+ I Electronics l ‘ 1 1 1 , Filters and Heat sinks yl I y MAXIMUM YIELD r AND RELIABILITY • EXTENDED MPPTN Using the latest modulation techniques, inspired by the most accurate and powerful motor control applications, has lead to the widest MPPt full power window in the solar market .
