Purpose of the Rules
• Coordination among existing solid waste management ARMs to ensure definitions and other operational requirements are consistent.
• Part of a larger effort to customize Solid Waste Administrative Rules.
• Establish the regulatory framework according to potential impact to human health and the environment.
• Consistent and equitable application of requirements.

Facilities/operations exempt from Solid Waste licensure
• Landfarms at CECRA remediation sites.
• Landfarms located within the licensed area of a licensed Class II facility.

Before landfarming, consider…
• Landfill disposal costs vs. site development, long-term operation and management, post-closure, and liability.
• Upfront costs of landfilling vs. landfarming.
• Is landfarming still the best decision?

New Definition
One-time Landfarm – means a landfarm facility for remediation of less than 2,400 cubic yards of non-hazardous contaminated soil generated from a single site, regardless of the source, and will not be used to treat contaminated soil on an on-going basis.
Note: Contaminated soil does not include concrete, wood, metal, or any other non-soil material.
