The operation will start in Adams and York Counties and move up the Juniata River and end in Huntingdon County.

The helicopter treating the Juniata River and creeks will be a black Bell 206 Long Ranger with the tail numbers N651HA.

Helicopter Applicators Inc. will be dispersing Vectobac SC, which is a Bti product manufactured by Valent Biosciences. Bti is short for Bacillus thuringiensis var. israelensis, which is a bacterial larvicide, not a chemical, and is the only product used in Pennsylvania's waterways for black fly suppression. Vectobac SC is a thick brown liquid resembling chocolate milk. The helicopter will fly low near tree top level and release the Vectobac SC at various predetermined positions on each stream.
