Guidelines Manual for Minimizing Water Quality Impacts from Highway Maintenance Practices. Volume 4

摘要

The manual, Volume 6 in a four-volume series of reports relating to water quality impacts of highway maintenance practices, provides practical guidance to highway agency maintenance personnel for minimizing impacts to water resources from maintenance practices while keeping highway agency costs at a minimum. The manual identifies those maintenance practices most commonly employed by highway agencies throughout the United States and describes each in terms of its potential for causing adverse impacts to water quality. Available mitigation measures for maintenance practices with the potential to impact water quality are identified, and guidance is given for selecting the most cost-effective practices.
