EXHIBIT A GENERAL SCOPE OF SERVICES

Grease Interceptor MCI Services at HJAIA Exhibit A; General Scope of Services

The Grease Interceptor (“GI”) Maintenance, Cleaning and Inspection (“MCI”) Services is essential for maintaining operational efficiency of Hartsfield-Jackson Atlanta International Airport (“H-JAIA”). The GI systems play a crucial role in ensuring the minimal interruption of food and beverage concessions, supporting the airport's broader objectives in providing exceptional customer service and operational efficiency. The primary goals of this contract include the prevention of grease buildup, the protection of the City’s capital investment, the insurance of regulatory compliance, and the reduction of disruptions to airport operations.

2. Project Description The Contractor will be responsible for the comprehensive maintenance of all GIs located within H-JAIA’s Central Terminal Passenger Complex (“CPTC”). At time of award, there will be sixty-nine (69) Grease Interceptors in operation, including fifty-five (55) below ground and fourteen (14) above ground. Of the fifty-five (55) Below Ground GIs, approximately ten (10) are located 5 to 10 feet below the surface and are designated as Deep Below Ground (“BG-D”). By the end of the 5-year contract, the total number of GIs will increase to seventy-six (76). Services shall be performed in accordance with the requirements outlined in this scope of work. See Figure 1 below for complete Grease Interceptor Inventory.

Note: The City of Atlanta, Department of Watershed Management, now uses the term Grease Trap (“GT”) for all grease waste collection devices. This scope uses "GI" to refer specifically to larger, exterior grease traps (1,500 gallons or above) for which MCI services are sought. Interior, Point-of-Use (“POU”) GTs under 200 gallons located within concession spaces are not included in this scope of work.
