THE BRONX - In addition to grimy roadways, New York City's street sweepers might soon clean up something else: parking rule violators.

The Bloomberg administration is seeking state approval to install cameras on some of the Sanitation Department's street cleaners in a pilot program aimed at taking the burden off traffic agents in enforcing alternate-side parking rules. The cameras would capture the license plates of cars parked illegally.

If the plan is approved, violators would receive a letter containing the date, time and location of their vehicle's street-sweeper encounter and at least one photograph snapped by the street sweeper's onboard camera.
