Revisor ID: R-04556
The MPCA plans to amend existing Minnesota Rules governing permits and solid waste landfills (chapters 7001 and 7035). This rulemaking was identified previously as the Construction and Demolition Debris Land Disposal Facilities (CDL) Rule, but is also called the C&D Rule.
The goal is to update these rules by incorporating lessons learned about the potential for groundwater impacts of unlined C&D landfills. MPCA monitoring has found pollutants in groundwater around unlined C&D landfills at levels which exceed standards to protect human health and the environment. Major rule concepts were developed using a variety of sources including information from other states in our region, a rule advisory committee known as the Rule Advisory Panel (RAP), the 2019 Report on Groundwater Impacts, the Sustainable Building Group, and Minnesota statutes and rules. An updated rule is now being drafted based on these major concepts. Public comment on the rule is part of the rulemaking process.

Background resources
MPCA draft rule summary (April 2025)
This is an overview of key provisions under consideration for these new rules. Many provisions described within the summary reflect changes made to rule concepts based on stakeholder feedback received to date. The main purpose of the document is to inform construction and demolition waste management planning grant awardees as they draft work plans in spring of 2025. The agency intended to publish draft rule text to support this planning work but has experienced delays.
This document is also being made available to key stakeholders and the public about proposed regulatory updates that affect landfill design, operation, monitoring, and closure requirements. These updates are consistent with modern landfill design and largely consistent with Minnesota rules governing mixed municipal solid waste (MSW) landfills. Concepts outlined are preliminary and subject to further refinement.
Informational meeting (August 2024)
In August and September 2024, MPCA staff shared the concepts behind the upcoming proposed rule changes at a series of stakeholder sessions across the state. Each session included information and discussion tailored to each location, including waste management strategies and potential options within that region. The session held at the MPCA office in Saint Paul on August 13 was also offered virtually and recorded (135 min).
Rulemaking update (November 2023)
Letter to facilities and via GovDelivery informing affected facilities of the proposed changes to the C&D rules so they could begin planning for transition to the new rules.
Rule advisory panel (2019-2021)
The rule advisory panel (RAP) was formed as a rule advisory committee to advise the agency on potential content of the new C&D Rule. The panel met from fall 2019 to spring 2021 and again in summer 2023. Members focused on the end-of-life management of C&D material. The role of the panel was to discuss and advise MPCA on topics directly related to C&D landfills, such as design and operation, prevention aspects, and water quality.
RAP members were selected based on expertise, ability to communicate within their sector, geographic area, ability to work on a team, ability to attend meetings and allocate time to the effort. Representation included C&D landfill owners and operators, environmental consultants, environmental organizations, county staff and one private citizen.
