§ 3-103 — Aircraft deicing

Sec. 3-103. - Aircraft deicing.

(a) Aircraft deicing (the removal or prevention of snow and/or ice with chemical substances) shall only be accomplished after the director's written acceptance of the user's detailed deicing plan. (b) Before granting written permission for aircraft deicing, the director will review the deicing plans, deicing manuals, and training materials; inspect any deicing equipment; and accept the containment and recovery plan that will be used by the lessee for aircraft deicing. (c) Use of chemical substances for the purpose of removing snow and/or ice shall comply with all regulatory measures, as they may change from time to time. (d) All deicing and anti-icing shall be performed in accordance with the airport's deicing program, which contains authorized deicing locations and procedures. The airport's deicing program is available from the operations division at (210) 413-4928 or the environmental stewardship division (210) 207-3862. (e) Best management practices should be used to minimize the use of glycol through proper application techniques. (f) To the extent possible, other deicing and anti-icing techniques should be used to minimize the use of glycol. These techniques are described in detail in FAA Advisory Circular 20-117 Hazards Following Ground Deicing and Ground Operations in Conditions Conducive to Aircraft Icing. (g) For safety reasons, efforts must be made to collect overspray from ramp areas if feasible to keep ramp surfaces clean and to avoid deicing fluids from entering the storm drains. Designated deicing areas have been established at the west, south, and east ramps. Deicing at the gates is prohibited. (h) Collected aircraft deicing and anti-icing fluids shall be disposed of or recycled in accordance with the Clean Water Act and U.S. Environmental Protection Agency Effluent Limitation Guidelines (ELGs), if any. (i) Weekly, each aircraft owner who uses deicing fluids must report quantities and concentrations of deicer used (inclusive of quantities disposed of or recycled) to the environmental stewardship division designated representative if any aircraft deicing fluids are used during the week. The week shall run Sunday through Saturday. Reports are due on Tuesday for the prior week. (j) As required by the TCEQ Texas Pollutant Discharge Elimination System Multi-Sector General Permit, deicing season is identified for SAT from October through March. Implementation of control measures, including best management practices, facility inspections and monitoring must be conducted with particular emphasis throughout the defined deicing season. (k) Each aircraft owner who uses deicing fluids must track and record the use of aircraft deicing fluids for the deicing year (July 1st—June 30th), including inventories on hand at the start and end of the deicing year. If a deicing contractor is used, the owner of the aircraft is still responsible for filing the annual report. These data shall be reported annually for use in projecting future infrastructure and staffing needs, and may become a reporting requirement of the airport's industrial stormwater permit. The annual aircraft deicing fluid use and inventory report must be submitted to the director by the end of the deicing year (June 30th). The report must include total gallons (neat) of Type I and Type IV deicing fluid applied during the deicing year just completed, as well as Type I/IV inventories on hand at the start and end of the deicing year.
