The department should use best management practices when contracting for or performing maintenance on the state's highways and rights-of-way. Although the publication "Storm Water Management Guidelines for Construction Activities" was developed for construction, it is a good guide and has measures that can be used directly for maintenance activities. One of the basic principles is to ensure proper use, storage and disposal of materials to minimize and/or prevent storm water pollution. The development and implementation of best management practices minimize runoff of contaminants from pavements and bridges.
