In order to keep our air clean, the Borough of Sewickley participates in the Clean-Idle Program. Currently two dump trucks and the street sweeper are certified clean-idle. As vehicles age, they will be replaced by clean-idle certified replacements. The Borough has also posted anti-idling signs in front of schools within the Borough to alert drivers that idling is restricted in the state of Pennsylvania and is enforced by the Borough of Sewickley.
