110(a)(1) Maintenance Plan for 8-hour Ozone April 13, 2011

Public Notice Report 

For the Section 110(a)(1) Maintenance Plan 

for the 1997 8-Hour Ozone Standard for 

Greensboro/Winston-Salem/High Point 

1-Hour Ozone Maintenance Area 

On February 25, 2011, a draft version of the North Carolina Section 110(a)(1) maintenance plan 

for the 1997 8-hour ozone standard for Greensboro/Winston-Salem/High Point 1-hour ozone 

maintenance area (referred to as the Triad area) was submitted to the U. S. Environmental 

Protection Agency (USEPA). A request for public hearing, in accordance with 40 CFR 51.102, 

and the public comment period were noticed in the local newspapers on Wednesday, March 2, 

2011. The public comment period was open from March 2, 2011 through April 1, 2011. No 

request for public hearing was received and the public comment period elicited comments from 

the USEPA. 

Background

Section 110(a)(1) of the Clean Air Act requires that each state adopt and submit to the USEPA a 

plan which provides for implementation, maintenance and enforcement of primary standards for 

all areas within the state. The USEPA stated that a 110(a)(1) maintenance plan is required for 

those areas that are designated as attainment/unclassifiable for the 1997 8-hour ozone standard 

and are designated as attainment for the 1-hour ozone standard with an approved maintenance 

plan. The Triad area meets these conditions and therefore North Carolina is required to submit a 

110(a)(1) maintenance plan for the area. The requirements of the maintenance plan include an 

attainment emissions inventory, a maintenance demonstration with a future inventory year, a 

commitment to continue ambient air quality monitoring, a contingency plan to ensure that any 

violations of the 1997 8-hour ozone standard is promptly corrected and verification of a 

continued attainment tracking mechanism. 

Summary of Public Notice and Comment Period

The public comment period was open from March 2, 2011 through April 1, 2011. The only 

comments received were from the USEPA, which are attached following this report along with 

the NCDAQ’s response to comments. The comments were minor and will be addressed in the 

final submittal. 

Conclusions

The NCDAQ believes it has adequately addressed the USEPA’s comments. The NCDAQ will 

be moving forward with the final submittal to the USEPA of the North Carolina Section 

110(a)(1) maintenance plan for the 1997 8-hour ozone standard for Greensboro/WinstonSalem/High Point 1-hour ozone maintenance area.
