[Draft 1] -- Draft 2. "An environmental assessment of maintenance practices along Yukon highway rights-of-way was undertaken by the Environmental Protection Service during the summer of 1983. Maintenance practices which were compatible with environmental quality, as well as those which presented environmental concerns were documented. The environmental concern noted most frequently was the impact that maintenance practices had on water quality. This impact is discussed in relation to the roadway embankment, backslopes, drainage controls, and stream crossings. Other maintenance practices discussed include the calcium chloride and vegetation control programs"--Abstract.
