Information about petitions to require agency rulemaking

All Current DEP Rules (off-site, Secretary of State)

The Department has two paths for rulemaking.

  • A process for routine technical rulemaking which is performed by the department's Commissioner, and
  • A second which requires all major substantive rulemaking to be performed by the Board of Environmental Protection.

Note: Categorizing rules as routine technical or major substantive is a matter of legislative discretion. Major substantive rules are reviewed by the Legislature before final adoption by the agency.

For more information contact Jeff Crawford (207) 287-7647.


Meetings

The Department generally holds meetings for considering rulemaking actions and public hearings on proposed rulemaking the first and third Tuesdays of the month or as needed. Major substantive rule proceedings are conducted by the Board of Environmental Protection. See the BEP meeting calendar for information.

Capter 101, Visible Emissions Regulation - Re-posting

Fact Sheet (PDF) :: Draft Rule (PDF) :: MAPA 3 Notice (PDF)

Concise Summary:

The Department is proposing to amend its Chapter 101: Visible Emissions Regulation. As the result of legal action against the U.S. Environmental Protection Agency (EPA), such exemptions have been found to conflict with Clean Air Act (CAA) requirements. As a result, the EPA has issued a State Implementation Plans (SIP) Call, identifying each state and state rule deemed in conflict with such CAA requirements. This proposed rulemaking rectifies language and requirements to bring the Chapter in compliance with the SIP Call and CAA requirements. These amendments will be submitted to the U.S. Environmental Protection Agency for approval in Maine's State Implementation Plan.

On July 18, 2018, the Department posted this proposal to a 30-day public comment period with an opportunity to request a public hearing; the comment period closed on August 17, 2018.

These changes include:

  • Specific exclusions have been added to Section 1(C) to clarify the Department's intent to exempt equipment subject to a visible emission standard under New Source Performance Standards (40 C.F.R. Part 60) or National Emission Standards for Hazardous Air Pollutants (40 C.F.R. Part 63) as well as units with a wet plume subject to operating limits for control of PM under National Emission Standards for Hazardous Air Pollutants (40 C.F.R. Part 63);

  • Section 2(A)(5) has been revised to retain the original visible emission standards for biomass and multifuel boilers, minus the periods of unlimited opacity;

  • Section 3(C) has been added to retain the ability for facilities to amend their license to establish alternative (site-specific) work practice standards during periods of startup and shutdown;

  • For units monitored by a Continuous Opacity Monitoring System (COMS), higher alternative limits have been added for up to 5% of the unit's operating time on a quarterly basis in lieu of utilizing work practice standards for periods of startup, shutdown, and malfunction; and

  • Sections 2(A)(4) and 3 have been revised to clarify requirements for combustion turbines as opposed to reciprocating engines.

Citizen Petition for Rulemaking to Reduce Greenhouse Gas Emissions - Comment Period Extension

Fact Sheet (PDF)

Concise Summary:

On January 24, 2018, the Department of Environmental Protection received a citizen petition (Citizen Petition for Rulemaking to Require the Maine Department of Environmental Protection to Fulfill its Statutory, Constitutional, and Public Trust Obligations to Reduce Greenhouse Gas Emissions Along a Trajectory that is Based on the Best Climate Science and that will Reduce the Impacts of Climate Change in Maine (GHG Petition)) to initiate rulemaking pursuant to 5 M.R.S. § 8055. The GHG Petition was signed by 696 registered voters,[1] and the Petition was verified and certified as required by Maine law. Therefore, pursuant to 5 M.R.S. § 8055, the Department is required to initiate rulemaking.

The Petitioners' proposed rules seek greenhouse gas emission reductions of at least 8 percent each year, which correlates to Maine reducing its greenhouse gas emissions to approximately 75 percent below 2003 levels by the year 2035. The proposals would: (1) create a new "Greenhouse Gas Emission Standards" rule which establishes a statewide greenhouse gas emission limit for each year beginning in 2020, and requires submission of greenhouse gas emission reduction plans for certain stationary sources and vehicle fleets; (2) establish a new rule addressing sulfur hexafluoride (SF6 - a greenhouse gas) emissions from gas-insulated electrical switch gear; and (3) amend ten existing rules to incorporate greenhouse gas standards and cross-reference the new Greenhouse Gas Emission Standards rule. For proposed amendments to Chapters 146, 148, 150 and 305, the Petitioners proposed language establishing emission limits for greenhouse gases, but left blanks for the actual numerical limits.

The GHG Petition, the Petitioners' proposed rules, and Materials Circulated During Petition Drive may be found here: http://www.maine.gov/dep/ftp/GHG_Petition/ A listing of verified voter signatures along with youth and non-voter signatures is available for review at the Department's Augusta Office.

Major Substantive

Chapter 692, Siting of Oil Storage Facilities

Fact Sheet (PDF) :: Draft Rule (PDF)

Concise Summary:

The Department is proposing to amend its Chapter 692 Siting of Oil Storage Facilities rule to provide flexibility to municipalities and businesses siting oil storage facilities, as long as certain criteria and design standards are met. This proposed language adds variance language to allow for more areas to be developed without negatively impacting groundwater or drinking water. Additional municipalities and businesses would be able to site oil storage facilities including those that were previously proposed and denied. These facilities would need to meet certain criteria and design standards to ensure that the risk or oil discharges and the likelihood of future groundwater contamination has been effectively minimized.

Proposed changes include:

  • Eliminating the need to confirm mapping already completed by the Maine Geological Survey by conducting a site-specific evaluation thus creating less work for applicants;
  • Allowing flexibility to expand on a contiguous parcel if owned as of September 30, 2001 for UST facility and September 30, 2008 for an AST facility if expansion on the contiguous parcel does not increase fuel storage capacity or facility area by more than 30%;
  • Allowing a variance procedure for a municipality located on a significant sand and gravel aquifer as long as certain standards are met;
  • Allowing for a variance procedure for a facility on a polluted high yield significant sand and gravel aquifer;
  • Clarifying the design standards for facilities subject to variance requests under sections 3(B), 4(C), 4(D) or 4(E);
  • Adding a variance transfer procedure; and
  • Modifying language including correcting typographical errors and providing definitions and language clarification
