Not at this airport. Even though they are encouraged to use the spray area bull-pen, they spray anywhere they want to. Without some sort of strong message from airport management, they continue to de-ice at their perspective gates which causes continual recovery issues.
Just get them to quit spraying at their gates!! How can you be expected to recover any Glycol? I guess the pilots would rather slop through the puddles doing their pre-flight inspection than have their ground crew push back and then deice.
