Infernal leaf blower on Paseo

Does anyone know the best way to lodge a complaint about the leaf blower used by the clean-up crew to sweep off the Paseo del Pescador? It's a labour-saving device that saves no labour (they have a person with a broom following behind anyway) and is a prolific generator of noise and air pollution. It takes about an hour to sweep around the bay and you hear its infernal drone every inch of the way. The bahia is a boisterous noisy joyful place but that thing is an abomination.

The thought of the fecal matter that blower is putting into the air is nauseating.
