Major category -A processing or monitoring category requiring more than 50 hours of agency time to process an application for a special use authorization (processing category 6 and, in certain situations, processing category 5) or more than 50 hours of agency time to monitor compliance with the terms and conditions of an authorization (monitoring category 6 and, in certain situations, monitoring category 5). Major categories usually require documentation of environmental and associated impacts in an environmental assessment and may require an environmental impact statement.

Minimum vegetation clearance distance -the calculated distance (stated in feet or meters) that is used to prevent flashover between conductors and vegetation for various altitudes and operating voltages. The MVCD is measured from a conductor's maximum operating sag to vegetation on NFS lands within the linear right-of-way for a powerline facility and on NFS lands adjacent to either side of the linear right-of-way for a powerline facility for purposes of felling or pruning hazard trees, which the owner or operator uses to determine whether vegetation poses a system reliability hazard to the powerline facility.
Minor category -A processing or monitoring category requiring 50 hours or less of agency time to process an application for a special use authorization (processing categories 1 through 4 and, in certain situations, processing category 5) or 50 hours or less of agency time to monitor compliance with the terms and conditions of an authorization (monitoring categories 1 through 4 and, in certain situations, monitoring category 5). Minor categories may require documentation of environmental and associated impacts in an environmental assessment.
Monitoring -Actions needed to ensure compliance with the terms and conditions in a special use authorization.
National Forest System land -all lands, waters, or interests therein administered by the Forest Service.
