Archived — Compost Rule Amendments

Minnesota Revisor's ID: R-04110

  • Final adoption in State Register: 12/22/2014
  • Effective date: 12/30/2014

The goal of amending the compost rules was to create a new section specifically appropriate for facilities limited to certain source-separated organics (the emphasis was on facilities that accept food waste and yard waste in appropriate proportions). Because of the nature of this material, MPCA set standards stricter than existing yard waste composting facility rules but less strict than solid waste composting facility rules. MPCA made no changes to existing rules for yard waste composting and solid waste composting.

Biodegradable (organic) municipal solid waste consumes landfill space and produces significant greenhouse gas emissions when landfilled. Instead of landfilling, composted organic material can be used as a soil amendment — a resource that can potentially displace some amount of petroleum-derived synthetic fertilizer and some best (management) practices for reducing stormwater runoff and surface water pollution.

Changes to chapters 7001 and 7035 address the combination of food and yard waste with the addition of bulking agents and remove  existing barriers to expanded composting of organics by clarifying requirements. Minor changes also clarify requirements, updated requirements removed obsolete language.
