Rapid City Solid Waste Division Customers:

As part of a continuing quality assurance effort, the Rapid City Solid Waste Division periodically tests the yard waste compost products to determine the quality of the compost offered for sale.  Recently, as part of that testing, the presence of three herbicides was detected.  The herbicides detected are: Clopyralid, Quinclorac, and MCPP. Since the discovery of these herbicides in our yard waste compost products, more extensive testing is being conducted.

What are these herbicides?

• Generally speaking, these herbicides target broadleaf plants, and are not harmful to turf grass.
• Clopyralid is considered a persistent herbicide or PH. Which means that it can be detected anywhere from several months to several years in soils or in compost that was made from vegetation previously treated with the herbicide.

How did these herbicides get into the compost?

• The Rapid City Solid Waste Division adds only water to the feedstock material from which the compost material is made. Our feedstock includes: tree branches, leaves, grass clippings, animal manures, untreated lumber products, and other organic material.
• These herbicides are used in our communities. Most likely one or more of our compost feedstock materials was treated with the herbicide, and at some point, delivered to the Solid Waste Facility for processing. Herbicides ARE NOT used as part of the yard waste composting process.

What will happen if I use compost products from the Solid Waste Division?

• At this point the recommendation is to not use the compost for any application where broad leaf plants (including ornamental plants) will be grown. This includes, but is not limited to, most common garden plants such as tomatoes, potatoes, legumes, lettuce, peppers, etc.

What is the Rapid City Solid Waste Division doing about this?

• More extensive testing is being conducted, including testing the different feed stocks separately in an effort to narrow down where these herbicides may be coming from. If a particular material is found to be the source of the herbicide, that waste stream will be managed separately to ensure that herbicide residues are kept out of the compost to the greatest extent possible.

What can I, the customer, do to help?

• Make sure you are not using any of the herbicides listed above on any yard waste material you bring to the Solid Waste Facility.
• If you do bring in material that may have herbicide residue, please let the Solid Waste Division staff know, so appropriate measures can be taken to segregate the material.

When using any herbicide, please follow all instructions and warnings provided by the manufacturer.
