NAAQS. This NPRM also proposed to approve into Maines SIP amendments to state regulations at 06096 CMR
Chapter 110, Ambient Air Quality Standards, and several conflict of interest COI provisions in Maines statutes, which support the states infrastructure submittal for the 2015
ozone NAAQS. The NPRM also proposed, based on the Chapter 110
amendments and the COI provisions, to convert to full approval a number of EPA conditional approvals of earlier Maine infrastructure SIP submissions for other NAAQS. The NPRM also proposed to approve a Maine SIP
submission that provides the states determination, via a negative declaration, that there are no facilities within its borders subject to EPAs 2016
Control Technique Guideline CTG for the oil and gas industry for the 2008 and 2015 ozone standards.
The NPRM addressed the following submissions from the Maine Department of Environmental Protection Maine DEP: A February 14, 2020, submission addressing infrastructure requirements for the 2015 ozone NAAQS; a May 28, 2019, submission of amendments to the aforementioned regulations; a September 4, 2019, submission of several COI provisions in Maine state law; and a May 14, 2020, negative declaration for the 2016 CTG for the Oil and Natural Gas Industry for the 2008
and 2015 ozone standards.
The rationale for EPAs proposed action is given in the NPRM and will not be restated here. No public comments were received on the NPRM.
II. Final Action EPA is approving most of the elements of the infrastructure SIP
submitted by Maine on February 14, 2020, for the 2015 ozone NAAQS.
Todays action does not include the good neighbor provisions i.e., CAA
section 110a2Di, also known as a states Transport SIP. EPA will address Maines Transport SIP for the 2015
ozone NAAQS in a future action.
EPA also is approving, and incorporating into the Maine SIP, the following regulation, submitted on May
