Each year, pesticide products are cancelled by the manufacturer or phased out by operations, leaving farmers and professional applicators with quantities of unwanted and/or unusable pesticides.  Due to the nature of these materials, there are often limited options available for responsible management.  The high cost of disposal prohibits many users from hiring waste disposal contractors to collect and dispose of these materials.  The waste pesticides may then become a safety hazard or environmental liability through long-term storage in barns and other areas in and around the farm or business.
CHEMSWEEP provides Pennsylvania farmers and other licensed pesticide applicators with a means to dispose of canceled, suspended or unwanted pesticide products.  By participating in this program, applicators can legally dispose of waste pesticides, generally at little or no cost.  Almost all of the waste pesticides collected are burned in EPA-approved incinerators.  The remaining pesticides are treated and placed in EPA-permitted hazardous waste landfills.
CHEMSWEEP has grown from the collection of a modest 30,000 pounds of pesticides from six counties in 1993, to a program that serves all of Pennsylvania, having collected over 2.3 million pounds of waste pesticides through 2015.
How to Participate:  Each year, CHEMSWEEP operates in a selected number of counties.  Licensed farmers, professional pesticide applicators and pesticide businesses in the counties selected for that year are eligible to participate.  If you are a pesticide applicator in agriculture, pest control, lawn care or other professional capacity, or a pesticide dealer, check the CHEMSWEEP 2016 map below to see if your county is eligible. If so, complete the CHEMSWEEP registration form and return to the address shown by the deadline of February 28. Future county collections will occur on the following schedule:
2017: Berks, Bedford, Bradford, Butler, Columbia, Cumberland, Fulton, Lawrence, McKean, Montour, Northumberland, Schuylkill, Sullivan, Warren, and York.
2018: Adams, Allegheny, Beaver, Cameron, Carbon, Centre, Chester, Clearfield, Clinton, Elk, Franklin, Jefferson, Lancaster, Lehigh, Monroe, Northampton, Pike, Potter and Washington.
2019: Bucks, Crawford, Dauphin, Erie, Fayette, Greene, Huntingdon, Juniata, Lycoming, Mercer, Mifflin, Montgomery, Perry, Philadelphia, Susquehanna, Tioga, Wayne, Westmoreland.
Each pesticide inventory received from farmers or other licensed applicators will be verified by a Pennsylvania Department of Agriculture (PDA) inspector.  PDA will then work with a waste disposal contractor to schedule the collections, which usually take place from July through October.  CHEMSWEEP will cover the cost of the first 2,000 pounds per participant. Participants with waste pesticides exceeding 2,000 pounds will be responsible for the cost of the excess amount and will be direct-invoiced by the PDA contractor at the contracted price at time of service.
Only pesticide products that are or have been registered for sale or use in the Commonwealth will be accepted in this program.  These materials are classified as Universal Waste Pesticides and will be collected, packaged, transported and disposed of in accordance with all applicable rules and regulations. The PDA contractor will become the generator of record for your waste pesticides at the time of collection.
Homeowners: CHEMSWEEP is not designed as a homeowner-oriented pesticide disposal program.  If you are a homeowner wishing to disposal of home and garden pesticides or other household waste items like used oil, paint, solvents, cleaners, etc., please see DEP’s Household Hazardous Waste Program or contact your county solid waste authority.
HHW Sponsors: If you are a municipal entity and wish to sponsor a Household Hazardous Waste collection event, it may be possible for you to utilize the CHEMSWEEP contract for your event. Please contact Donald Gilbert for additional information.
