Bluebonnet to resume using herbicides in its vegetation management plan

A two-person crew sprays a herbicide to control vegetation in a utility right-of-way. Bluebonnet will resume using herbicides this year in some of its rights-of-way. It’s an environmentally safe, cost-effective method for the co-op to increase the miles of right-of-way it maintains per year.

With more than 11,000 miles of power lines to maintain, folks are probably used to seeing Bluebonnet’s crews or contractors cutting trees and vegetation in our utility easements. Workers wielding chain saws or skillfully guiding heavy equipment armed with multiple saw blades trim or remove vegetation that could encroach on power lines.

The work is performed to provide safe, reliable electric service and is done according to our vegetation management plan.

This year, we will resume using another method to remove trees and plants in our easements, or rights-of-way. For the first time since 2011, we will incorporate herbicides into our vegetation management plan. The herbicides will be used in areas that were mechanically cut within the last two or three years.

Using herbicides is a cost-effective way to increase the number of miles of right-of-way we maintain per year. Cutting trees, limbs and other vegetation costs more and has to be done more frequently. Cutting also causes many species of trees and shrubs to grow more limbs, but herbicides cause the vegetation to die and quickly decay.

Right-of-way maintenance in areas where herbicides are used won’t have to be addressed as often and will cost less because vegetation won’t grow back as quickly compared to areas maintained solely by mechanical cutting.

We use certified arborists to examine vegetation in our rights-of-way to determine if using herbicides is appropriate. If so, they will recommend the type and amount of herbicide to use.

Our contractors who spray the rights-of-way are licensed by the Texas Department of Agriculture for commercial application of herbicides. In the endangered Houston toad habitat, they will only use herbicides that are approved for use according to our habitat conservation plan, which was developed with the U.S. Fish and Wildlife Service and Texas Parks & Wildlife Department.

The herbicides will be applied only to vegetation near the ground by contractors walking the right-of-way using hand-held spray applicators or driving all-terrain vehicles with mounted spray applicators. The two-person crews typically consist of one licensed applicator and a worker to assist with driving the all-terrain vehicle and carrying the herbicides.

In January 2009, we held a series of public meetings throughout our service area to discuss with landowners and members of the community the use of herbicides to control vegetation in our rights-of-way. Some landowners and residents were concerned about the environmental impact of using herbicides, but most who attended the meetings either didn’t object or expressed support for the program.

Our contractors will contact residents before work is done near their homes or businesses, whether they will be doing mechanical cutting or spraying herbicides. If no one is home, a gate or door hanger is left with information about the work to be performed and a phone number to call with questions.

An overwhelming majority of the members we contact are supportive of spraying herbicides on their property. Some members ask what herbicides are used and how, when and where they’re applied before they consent to spraying on their property.

A few members have asked us not to use herbicides on their property and, of course, we respect their choice. In those cases, we mechanically cut the vegetation in those rights-of-way.
