Specifications include, but are not limited to: 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. If such a condition develops the contractor will issue a Notice to Airman (NOTAM) to the appropriate Automated Flight Service Station (AFSS) or contact the Department representative in order to enable the representative to issue an appropriate Notice to Airman (NOTAM) describing the condition.
