Narrative:

While working local control at capitol airport, I had given the runways to ground for snow removal as there was no traffic. 15 mins later atx X called for takeoff clearance. Complacency on the position with 1 aircraft, I cleared atx X for takeoff and he had to abort observing a plow grossing the runway downfield. Aviation requires attention to detail and awareness at all times, not just when you get busy.
