CHEMSWEEP provides Pennsylvania farmers and other licensed pesticide applicators with a means to dispose of canceled, suspended or unwanted pesticide products. Through CHEMSWEEP, applicators can legally dispose of unwanted pesticides, generally at little or no cost. Almost all 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 collected over 3.2 million pounds of unwanted pesticides through 2023!

CHEMSWEEP operates in a selected number of counties each year. 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 2024 map below to see if your county is eligible. If so, complete the CHEMSWEEP registration form ​on the link to the right, (Public Inventory Submissions) and submit by the deadline of March 31, 2024.

Please note - Public Inventory Submissions website opens in December.


Future collections will occur on the following schedule:

2024: Armstrong, Blair, Cambria, Chester, Clarion, Delaware, Forest, Indiana, Lackawanna, Lancaster, Lebanon, Luzerne, Snyder, Somerset, Union, Venango, Wyoming.

2025: Bedford, Berks, Bradford, Butler, Columbia, Cumberland, Fulton, Lawrence, McKean, Montour, Northumberland, Schuylkill, Sullivan, York, and Warren.

Each pesticide inventory submitted 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.

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 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 James Cunningham for additional information.​
