A-2.1.6 Floor and Ramp Construction
All floors and ramps must be constructed of concrete having a minimum of four inch thickness and shall include steel reinforcement of a type approved by the Airport Manager. A stiff broom finish is required on exterior ramps.
Bi-fold doors are recommended because of their ease of operation during the winter months. Approved swing out, overhead or sliding doors may also be used. All pedestrian doors must be of pit-finished metal construction.
The gradient of the finished floor of any proposed structure and the surrounding surfaces shall provide for positive flow of water into the existing airport storm sewer system. In areas where no storm sewer exists, the Airport Manager may require the installation of inlets and pipe designed for anticipated maximum flow and loading to be installed and attached to the existing storm sewer system. An approved system of oil/water separators may be required to prevent contamination of surface or ground water resources.
Oil/Water Separators Aviation repair facilities and paint shops, dealerships, fuel stations, equipment degreasing areas, and other facilities generating wastewater with oil and grease content are required to pre-treat these wastes before discharging to the sanitary sewer system. Pre-treatment requires that an oil/water separator be installed and maintained on site.
Oil/water separators for commercial/industrial processes must be sized on a case-by-case analysis of wastewater characteristics. Typically a minimum capacity of 750 gallons is required for small fuel stations, aviation repairs, and light commercial sites; 1500 gallon capacity for large-scale aircraft washing and steam cleaning facilities. The ultimate discharge must be directed to the sanitary sewer system. All units regardless of size shall be fitted with a standard final-stage sample box and spill-absorbent pillows.
Oil/water separators shall be commercially manufactured and sized for the intended discharge rates for the facility where it is to be installed.
