WEEKLY NOTICES OF STATE RULEMAKING
Public Input for Proposed and Adopted Rules

Notices are published each Wednesday to alert the public regarding state agency rulemaking. You may obtain a copy of any rule by notifying the agency contact person. You may also comment on the rule, and/or attend the public hearing. If no hearing is scheduled, you may request one -- the agency may then schedule a hearing, and must do so if 5 or more persons request it. If you are disabled or need special services to attend a hearing, please notify the agency contact person at least 7 days prior to it. Petitions: you can petition an agency to adopt, amend, or repeal any rule; the agency must provide you with petition forms, and must respond to your petition within 60 days. The agency must enter rulemaking if the petition is signed by 150 or more registered voters, and may begin rulemaking if there are fewer. You can also petition the Legislature to review a rule; the Executive Director of the Legislative Council (115 State House Station, Augusta, ME 04333, phone (207) 287-1615) will provide you with the necessary petition forms. The appropriate legislative committee will review a rule upon receipt of a petition from 100 or more registered voters, or from "...any person who may be directly, substantially and adversely affected by the application of a rule..." (Title 5 Section 11112). World-Wide Web: Copies of the weekly notices and the full texts of adopted rule chapters may be found on the internet at: http://www.maine.gov/sos/cec/rules. There is also a list of rulemaking liaisons, who are single points of contact for each agency.


PROPOSALS

AGENCY: 06-096 - Department of Environmental Protection (DEP)
CHAPTER NUMBER AND TITLE: Ch. 101, Visible Emissions Regulation
PROPOSED RULE NUMBER: 2018-P157 (2nd publication)
BRIEF SUMMARY: Emissions into the ambient air from facilities, both licensed and unlicensed, are subject to visible emissions standards. These standards may be located in the Department’s Ch. 101, Visible Emissions Regulation, in State-determined Best Available Control Technology (BACT) and Best Practical Treatment (BPT) determinations, and in federal National Emissions Standards for Hazardous Air Pollutants (NESHAP) and/or New Source Performance Standards (NSPS). Emissions sources identified in this chapter include sources which may not otherwise be subject to visible emissions requirements.
Currently, Ch. 101 includes up to two six-minute exemptions from visible emissions standards per three-hour period for certain regulated emissions units. 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 and 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.
Ch. 101 was originally promulgated in 1972 and was most recently updated in 2003. Since that time, the Department and EPA have identified several revisions that will provide greater clarity and flexibility to the regulated sources while accommodating real and unavoidable fluctuations in operations. Changes in this proposed rulemaking are more consistent with applicable federal requirements and do not increase the regulatory burden on affected facilities.
The proposed changes include the following:
* Removal of the “unregulated” exemption periods and inclusion of new, alternate provisions for periods of startup, shutdown, or malfunction, allowing the option of compliance with work practice standards to minimize emissions during such times instead of a numerical opacity limit;
* Clarification of exemptions from the chapter, including units whose visible emissions are regulated through another State rule, visible air contaminants emitted for the purpose of visible emissions observer training, and visible air contaminants emitted for the purpose of Predictive Emission Monitoring Systems (PEMS) research that has been approved by the Commissioner and EPA;
* Clarification of the applicability of the annual capacity factor visible emission standard;
* Inclusion of a definition of distillate fuel, for the purposes of the chapter;
* Removal of specific visible emissions standards for Kraft recovery furnaces, since all such units are subject to visible emission standards in applicable federal rules.
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. After reviewing public comments, the Department revised its proposals and provided an opportunity for additional public comment pursuant to 5 MRS §8052(5)(B) on additional changes to the proposals that may be substantial. 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 CFR Part 60) or National Emission Standards for Hazardous Air Pollutants (40 CFR 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 CFR 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.
Please note that the Department is not accepting additional comments on other portions of the proposals at this time.
The Department may submit these amendments to the U.S. Environmental Protection Agency for approval as an amendment to Maine's State Implementation Plan. Copies of these rules are available upon request by contacting the agency contact person or on the DEP website at 
http://www.maine.gov/dep/rules/. Pursuant to Maine law, interested parties are publicly notified of the proposed rulemaking and are provided an opportunity for comment. Written comments may be submitted by mail, e-mail or fax to the contact person before the end of the comment period. To ensure the comments are considered, they must include your name and the organization you represent, if any. 
PUBLIC HEARING: No public hearing is scheduled (there is a 30-day written comment period). A public hearing will be held if requested before the end of the comment period.
COMMENT DEADLINE: November 2, 2018 - 5:00 p.m.
