The Pennsylvania Department of Environmental Protection (DEP) will conduct a black fly suppression aerial spraying operation on Wednesday, August 1, 2012.  Aerial spraying will be conducted along the Delaware River in Northampton and Bucks Counties in PA and Warren, Hunterdon, and Mercer Counties in NJ.  The operational area will be between Slateford, PA/Columbia, NJ and Yardley, PA/Trenton, NJ.

This operation should begin at approximately 8 a.m. in Pottstown along the Schuylkill River in Berks County and continue to the Lehigh and Delaware rivers throughout the day.  Several landing sites may be utilized during this operation. Landing zones (LZ's) may include: Upper Mount Bethel Park,Upper Mt. Bethel Twp., Northampton Co.;Berry Hollow Road Farm, Lower Mt. Bethel Twp., Northampton Co.;Braden Airpark (Easton Airport), Forks Twp., Northampton Co.; Clemens Property, Durham Twp., Bucks Co.; Erwinna/Delaware Valley Fire Co., Tinicum Twp., Bucks Co.;Thorpe Farm,Upper Makefield Twp., Bucks Co.

Ag Air, LLC of Thomasville, PA is the scheduled contractor. The operation is scheduled to use a white and blue Bell Jet Ranger helicopter with tail number N16979.

DEP officials will be applying VECTOBAC 12AS to the waterways to reduce the numbers of adult black flies that hatch from the rivers and streams.  This product is a brown, slightly sticky liquid with an odor resembling fish oil.  The active ingredient in Vectobac is Bacillus thuringiensis israelensis (Bti) which is a naturally occurring soil bacterium and not a synthetic pesticide.  A product label and MSDS are available upon request.  Vectobac is applied perpendicular to the stream flow in multiple locations along the aforementioned rivers or streams by a low flying helicopter.  The discharge comes from a boom arm attached to a large tank mounted underneath the helicopter.
