NOXIOUS WEED MANAGEMENT 



• Surface blading to remove weeds before the seed-set stage may be required on roads affected by 

 the proposal. 



• All tracked and wheeled equipment will be cleaned of noxious weeds prior to beginning project 

 operations. The contract-administrating officer will inspect equipment periodically during 

 project implementation. 



• Prompt vegetation seeding of disturbed roadside sites will be required. Roads used and closed 

 as part of this proposal will be reshaped and seeded. 



HERBICIDES 



To further limit the possible spread of weeds, the following integrated weed-management mitiga- 

 tion measures of prevention and control will be implemented: 



• Road-construction and skidding equipment will be cleaned of mud and weed plant parts prior 

 to entering the site. "^ "* 



• Disturbed roadsides and landings will be seeded with site-adapted grasses. So grass seeding 

 will be effective, seeding will be completed concurrently with road construction. 



Herbicide Application .^ i 



To reduce risk to aquatic and terrestrial resources, the following will be required: t 



• All herbicides will be applied by licensed applicators in accordance with laws, rules, and 

 regulation of the State of Montana and Flathead County Weed District. 



• All applications will adhere to Montana's Best Management Practices and the herbicide's 

 specific label guidelines. 



• Herbicide application will not be general, but site specific, to areas along roads where 

 noxious weeds are occurring. All no-spray areas will be designated on the ground before 

 applications begin. 



• Herbicides will be applied to areas where relief may contribute runoff directly into surface 

 water. 



• Application will applied on calm, dry days to limit drift and possible surface movement off 

 road prisms.
