How to Participate in MassDEP Hazardous Waste Permitting Decisions

MassDEP seeks input from the public - including individuals, communities, and groups - before it issues certain types of hazardous waste management permits or approvals.

Either when a proponent applies for a hazardous waste license or permit, or before MassDEP makes a final decision, the agency accepts public comment on the proposal for a specific period of time. In some cases, MassDEP also schedules a public hearing or meeting so it can provide additional project information and/or receive public feedback. Learn more below.

The information on this page is intended to help you understand how and when you can be part of the review and decision-making process. See also: MassDEP Public Hearings & Comment Opportunities

Hazardous Waste Facilities and Processes

Permit Category & Explanation:

Hazardous Waste Treatment, Storage, or Disposal Facility License or Renewal

A proposal for a new hazardous waste treatment, storage or disposal facility in Massachusetts must undergo extensive review by several state and local agencies. Steps in the process include:

  • Massachusetts Environmental Policy Act (MEPA) review by the Executive Office of Energy and Environmental Affairs;
  • Site Assignment reviews and determinations by the local Board of Health and the Massachusetts Hazardous Waste Site Safety Council (currently represented by MassDEP);
  • Development of a Siting Agreement between the facility developer and the “Local Assessment Committee” of the host municipality; and
  • Issuance of a Hazardous Waste Treatment, Storage or Disposal Facility License by MassDEP.

There are opportunities for public involvement at every step of this process. As part of its review of a new facility license application, MassDEP provides opportunities for the public to comment on a draft license or proposed license denial. The agency considers public comments before making a final determination. There also are opportunities for the public to comment when new facility proposals undergo MEPA and Site Assignment review, in each case provided by the state or municipal reviewing agency.

MassDEP hazardous waste treatment, storage or disposal facility licenses are issued for terms of five years. A facility owner/operator must apply to renew an existing license for another five years before the initial term expires. Unless the renewal involves expansion of the facility, neither MEPA nor Site Assignment review are required. Similarly, if the renewal does not require changes in the initial Siting Agreement between the facility developer and the host community's Local Assessment Committee, the initial Siting Agreement remains in place. See Additional Resources below to learn more.

Levels of MassDEP Oversight

MassDEP regulates facilities of varying sizes and complexity in different ways:

  • Large, complicated operations are required to obtain project- or site-specific permits or approvals before they can be built and/or begin operating.
  • Many smaller facilities and simpler processes are subject to general permits that contain specific performance standards established by regulation.
  • Other operations are required to periodically report data to MassDEP and/or certify to the agency that they are complying with the environmental requirements that apply to them.

While there are no public notice or comment periods associated with facilities subject to general permits or reporting/certification requirements, most of the documents they submit to MassDEP are available for public inspection at the agency's regional offices.
