4 EXHIBIT A SCOPE OF WORK FOR THE OPERATION AND MAINTENANCE OF ASHPHALT AND CONCRETE RECYCLE FACILITY MANAGEMENT A. INTRODUCTION Operator will operate and maintain two sites for the purposes of recycling asphalt and concrete removed from and then reused on projects at DEN. Receipt of asphalt and concrete from third parties is not allowed. Sales to third parties is allowed as described below. B. Facility Design/Construction Aerial photos of the two recycle yards as they generally exist at the time of execution of the Agreement are attached to Exhibit A as Fig. 1-1 and Fig These areas are referred to as the Recycle Yards. Within ten (10) calendar days of receipt of Notice to Proceed, the Operator is to develop and submit to the Project Manager an engineered yard layout identifying: receiving area(s), sorting and stockpiling area(s), finished product areas, locations of office trailer(s), scale(s), entrance/exit gates, site utilities, crusher, concrete wash out pit, perimeter fence, etc. for approval. The Operator will provide any additional signage, fencing, lighting, security and safety measures necessary. Stockpile heights above street-light level must be approved by the FAA through the FAA Form 7460 process. The Form 7460 process will be initiated through the DEN Project Manager. Within ten (10) calendar days of receipt of an approved site layout plan the Operator will proceed with implementation of the approved layout. The Operator will provide the Project Manager with a copy of the as-built site layout. All work, equipment and materials needed to plan and implement the approved site layout plan will be at the Operator s expense. For any structures and appurtenances that the Operator wishes to install, the Operator shall prepare and submit to the Project Manager for approval, a scaled site layout plan that identifies the location of the structure along with detail drawings and/or material information that clearly depicts the item(s) the Operator wishes to install. C. General Operation and Maintenance Requirements 1. The Operator will provide all equipment and staff necessary to operate and maintain asphalt, concrete and concrete slurry recycle facilities at DEN. This includes, but is not limited to; providing secure recycle yards, the inspection and acceptance of recyclable material from DEN, the acceptance and processing of concrete slurry, the crushing of material to meet DEN specifications, the ability to market and sell excess product to third parties, and meeting all federal, state and local laws and permit requirements to operate and maintain recycle facilities 2. The recyclable materials are stored in a yard at 71st Avenue & Jackson Gap Street (7230 Jackson Gap Street, Denver, CO 80249) and in a yard at 110th Avenue, west of Queensberg St. (7160 N. Scottsburg Place, Denver, CO 80249) (the "Recycling Yards"). Both Recycling Yards shall be kept secure so the Operator can inspect and monitor the receipt and sales of material. No utilities are provided at either yard.

5 3. Ownership of materials: a. Existing Materials are DEN property: Both raw and processed materials present in the Recycling Yards on the execution date of this contract are and shall remain the property of DEN. This includes all raw materials that have not been sized for crushing, all sized materials that are ready for crushing and any and all materials that have been processed and are ready for sales. These materials, regardless of quantity, may remain in the Recycling Yards at no charge to DEN, and Operator shall impose no charges on DEN or its contractors for use of these materials. b. Unfinished materials are DEN Property: Raw material delivered to the Recycling Yards during the contract and any materials that is sized and ready for crushing but otherwise are unprocessed are the property of DEN. Operator shall be paid a drop fee by DEN or DEN contractors to take delivery and size these materials to 2 x 2 pieces. No storage fees or similar charges may be imposed on DEN for unsaleable materials. c. Processed material: Operator may process received materials and existing sized materials into a marketable product at its own cost. Upon such processing, the materials will become the property of the Operator. d. To avoid excess accumulation of materials the Operator will be allowed to market and conduct third party (i.e. Customers that are neither DEN, FAA, nor their contractors) sales of recycled products subject to sales limitations as specified below. Operator shall accommodate fluctuations in DEN material requirements. Third party sales are limited to 45% of the total tons of materials produced unless the limitation must be raised to avoid excess accumulation of materials. Invoices for third party sales must be approved monthly by DEN. The negotiated 3 rd party sales commission must be applied to and paid to DEN for all such sales. DEN has been generating 100,000+/- tons of concrete rubble and 15,000+/- tons of asphalt for the past few years. The quantity of recycled material used has varied considerably, approximately k ton per year. These numbers are an approximation and DEN does not guarantee the actual quantities of rubble that will be generated or used. e. Providing finished material to DEN, FAA, and contractors: Upon request, Operator will provide finished material to DEN, the FAA, and their contractors at rates agreed upon in this contract. Typical gradations that will be required will be, but not limited to: Class 6 & Class 5 - CDOT Recycled Concrete Base Class 6 & Class 5 - CDOT Recycled Asphalt Base Class 6 & Class 5 - CDOT Recycled Comingled Base Class 1- CDOT Structural Fill -2" X ¾" Concrete Dry Screened Rock -4" X 2" Concrete Dry Screened Rock ASTM (#57/#67) Concrete Dry Screened Rock DIA Stone (6" & 12") 3/8" Fines Custom orders as may be requested 4. The Operator shall develop and maintain a Quality Control Program that includes the identification of testing required for processed materials, protocols and frequency. The Quality Control Program will be submitted to DEN for approval. 5. Equipment. The Operator must enumerate and submit a list of equipment that he intends to utilize to carry out and complete the tasks of receiving, crushing and grading of concrete and asphalt

6 materials, and selling of material to DEN or third parties.. Operator is expected to provide its own scales. However, the scale at the Queensburg Yard is owned by DEN. The Operator may use this scale but will be required to pay all costs of maintenance, operation, repair, and certifications. 6. Operation The Operator will conduct business at both yards as needed to accommodate firstparty, second-party and third-party sales. D. Environmental Requirements See Exhibit C for the full range of Environmental Controls that are the responsibility of the Operator. The Operator shall inspect and have the ability to detect contaminated materials upon the receipt of the materials or during handling and prior to processing. Physical and chemical analyses and tests may be required to determine if the material meets the criteria set forth in State of Colorado, CDPHE, Hazardous Materials and Waste Management Division (HMWMD) regulations. The Operator shall pay for such chemical analyses and will coordinate with local authorities to determine the quantity and origin of samples analyzed for any questionable material. The Operator will provide the classification of the material to the City. Regardless of when found, contaminated materials shall either not be accepted, or, if found after acceptance, the originator shall retrieve the contaminated materials. Otherwise, the Operator will be required to dispose of them at a state approved disposal site at no cost to DEN. The Operator will be responsible for the cleanup and proper disposal of contaminated materials to an approved site. Both recycle yards shall be kept neat and orderly. Clean dirt that accumulates from the receipt of recyclable material may be disposed of at existing stockpiles on DEN property as directed by the DEN Project Manager. Steel materials embedded in the recycled materials and salvaged shall be sold to metal recyclers when feasible. All waste materials shall be taken to Denver Arapahoe Disposal Site (DADS) as required by the Executive Order and described in Exhibit C on an as needed basis. E. Safety Plan The Operator will develop and provide two copies of its safety program to the DEN Project Manager for review at least ten (10) days before the on-site work begins. The Operator s program must meet at a minimum all applicable federal, state and local government requirements.
