Charlotte, Raleigh/Durham, and Winston

- Salem c arbon m onoxide m aintenance a reas was

submitted to the U. S. Environmental Protection Agency (USEPA). A request for public hearing,

Background

The Charlotte area experienced violations of the NAAQS in the late 1970's and was designated

as nonattainment for CO in 1978. The Charlotte, Raleigh/Durham, and Winston

- Salem areas

were recommended as nonattainment for CO by the Governor in a March 15, 1991 letter to the

US EPA Region IV Administrator as required by section 107(d)(1)(A) of the 1990 Clean Air Act

Amendment ( CAAA )

.

Although the Charlotte area had an attaining design value of 8.4 ppm, based on 1988 and 1989

data, the 1978 nonattainment designation was reaffir med by operation of law on the day of

enactment of the 1990 CAAA. Therefore, the Charlotte area was designated as "not

- classified"

and was given, under the CAAA, 5 years from the date of official designation to attain the

standard and therefore had an att ainment deadline of November 15, 1995.

The Raleigh/Durham and Winston

- Salem areas were designated as nonattainment and classified

as "moderate" under the provisions outlined in Sections 186 and 187 of the CAAA. The design

values were 10.9 ppm and 9.7 ppm (based on 1988 and 1989 data) for Raleigh/Durham and

Winston

- Salem, respectively. Since the design values were less than 12.7 ppm, both areas were

designated as "low moderate". With a moderate designation, both areas had until December 31,

1995 to attai n the standard.

In October 1994, the State of North Carolina submitted a redesignation request to the USEPA

and the area was designated attainment/maintenance for CO in September 1995.

In April 1994, the State of North Carolina submitted a request to the USEPA to redesignate the

Winston

- Salem area to maintenance status based upon three years of clean air quality data. In

November 1994, this area was redesginated to attainment/maintenance for CO.

# For the Raleigh/Durham area, the State submitted a request to the USEPA to redesignate this

area to maintenance in October 1994 and was redesignated to attainment/maintenance for CO in

September 1995. In October 1995, the State submitted a revision to the motor vehicle emission

budgets in the maintenance plan.

I n March 2005, the State submitted the second maintenance plan to the USEPA for all three

areas. This plan was approved by the USEPA in March 2006, and a clarification regarding this

approval was published in June 2007. The June 2007 clarification was wit h respect to moving

the oxygenated fuels program to the contingency measures.

North Carolina has chosen to use the limited maintenance plan option for this revision to the

second maintenance plan.
