St. Charles County, MO Trash & Recycling: Yard Waste Collection (2026)

430, adopted under the county's Solid Waste Management Code (Chapter 240, Article IV), lists the duties every permitted solid waste hauler owes residential customers. Subsection (A)(2) requires each permittee to "make available for an additional fee collection of yard waste once a week between April first (1st) and November thirtieth (30th) of every year" and to deliver everything collected to an approved transfer station or composting facility, so haulers cannot simply landfill it. The same subsection sits alongside the permittee's other core duties: weekly trash collection with an optional twice-weekly upgrade under (A)(1), on-request weekly recyclables collection under (A)(3), and billing residential customers at prevailing fair market rates under (A)(4).

201 defines "yard waste" broadly as source-separated leaves, grass clippings, yard and garden vegetation generated by residential activities, plus Christmas trees, stumps, roots, shrubs with intact rootballs, logs, felled trees and tree limbs "regardless of size," a definition the county amended by Ordinance No. 23-092 in October 2023 to add the tree and limb language. 420's permit-issuance standards. Because the November 30 cutoff falls outside the primary spring/summer growing season, residents who generate yard waste in December through March have no guaranteed hauler pickup and must hold or self-haul it to a transfer station until the seasonal service resumes April 1.
