To limit polluted runoff into county waterways as a result of road work, Clark County's Operations Department limits spray applications to the tops of shoulder areas in rural settings, and mainly uses mechanical means such as mowing or brush cutting to control nuisance vegetation. The department also uses alternatives to diesel to clean asphalt/oil equipment and tools, and has installed drip pans to help collect excess oil from equipment. Additionally, they have reduced the amount of oil used in cold mix overlays and now use polymer modified oil in chip sealing to reduce the chance of oil runoff.

Noxious weeds are controlled through a contract with Clark County Vegetation Management, which uses a spot-spray program that targets only the noxious weeds for control, greatly reducing the amount of pesticides applied.
