Specifications include, but are not limited to: Winter Maintenance - i. The Contractor shall begin snow control efforts at a time no later than when two (2) inches of snow or one half (1/2) inch of slush has accumulated on runway or taxiway surfaces. In all cases, the contractor shall begin snow removal efforts with sufficient time to allow completion of normal snow removal on the runway, taxiway and apron surfaces before the first scheduled air carrier flight departure or arrival. Snowdrifts and berms will not be allowed to develop on the airport's aircraft movement areas (inside the edge lights or cones) unless the storm is so severe that reasonable efforts to remove snow are unsuccessful. In these conditions, the Contractor may cease snow removal operations until the storm subsides to the point where snow removal efforts are effective. ; Runway, Taxiway and Safety Area shall be plowed free of loose snow full width and length. Snow shall be placed off aircraft movement areas so as not to create any hazardous conditions, future drifting and maintenance problems Summer Maintenance - i. All areas on the airport where aircraft operate, except private leasehold property, will be maintained clear of rocks two (2) inches or more in diameter and any foreign objects. These areas will be maintained free of holes or depressions that exceed 3 inches in depth which may affect directional control of an aircraft. Should potholes, ruts, etc. develop, they will be smoothed out as soon as possible. ; Once each summer, all brush and weeds will be cut around the runway, ramps, taxiways, runway and taxiway lighting and threshold markers and the SREB. The Contractor shall conduct minor brush cutting one hundred (100) feet beyond the edges of the runway and one thousand (1,000) feet beyond the thresholds/ends, unless these dimensions encroach upon other than airport property, in which case, cutting will terminate at the property line.
