attainment emissions inventory; 2 a maintenance demonstration; 3 a commitment for continued air quality monitoring; 4 a process for verification of continued attainment; and 5 a contingency plan.2 PADEPs February 27, 2020 submittal fulfills Pennsylvanias obligation to submit a second maintenance plan and addresses each of the five necessary elements.
As discussed in the February 9, 2021
NPRM, EPA allows the submittal of a limited maintenance plan LMP to meet the statutory requirement that the area will maintain for the statutory period.
Qualifying areas may meet the maintenance demonstration by showing that the areas design value 3 is well below the NAAQS and that the historical stability of the areas air quality levels indicates that the area is unlikely to violate the NAAQS in the future. EPA evaluated PADEPs February 27, 2020 submittal for consistency with all applicable EPA
guidance and CAA requirements. EPA
found that the submittal met CAA
section 175A and all CAA requirements, and proposed approval of the LMP for the Erie Area as a revision to the Pennsylvania SIP. Other specific requirements of PADEPs February 27, 2020 submittal and the rationale for EPAs proposed action are explained in the NPRM and will not be restated here.
III. EPAs Response to Comments Received EPA received four comments on the February 9, 2021 NPRM but only one that was adverse and relevant to this action. All comments are in the docket for this rule action. A summary of the relevant adverse comment and EPAs response is provided herein.
Comment: The commenter asserts that the LMP should not be approved because Pennsylvania identifies no actual contingency measures.
According to the commenter, a contingency measure is supposed to be a known measure that can be quickly implemented by a state in order to prevent the violation of the NAAQS.
The comment asserts that the plans current contingency measures are defective because they allegedly will not be evaluated and determined until after an exceedance of the NAAQS has 2 Procedures for Processing Requests to Redesignate Areas to Attainment, Memorandum from John Calcagni, Director, Air Quality Management Division, September 4, 1992 Calcagni Memo.
3 The ozone design value for a monitoring site is the 3-year average of the annual fourth-highest daily maximum 8-hour average ozone concentrations.
The design value for an ozone nonattainment area is the highest design value of any monitoring site in the area.
