1 State Implementation Plan (SIP) Development Process Presentation to: Granville County Board of Commissioners Donnie Redmond July 5, 2005

2 2 Summary What are the air quality issues? How do they affect Granville County? What is being done about it? What do you need to remember from this presentation?

3 3 What are the air quality issues? Federal Clean Air Act –Ozone –Fine particles (PM2.5) –Carbon monoxide –Greenhouse gases Ozone is the pollutant of primary concern –Entire metro area is included

4 4 How does it affect Granville County? Designation as nonattainment –New Source Review (NSR) –Transportation conformity –State Implementation Plan (SIP)

5 5 NC 8-hr Ozone Nonattainment Areas

6 6 What is being done about it? Attainment demonstration –Essentially, a modeling exercise to demonstrate that the State has a valid plan to attain the standard –I.e., computer projection of future air quality Redesignation request –Separate process undertaken once local field monitors show standards have been met –I.e., actual measurement of current air

7 7 Attainment Demonstration Why is it important? –Determine whether we have to add more environmental programs to meet the Federal standards

8 8 Attainment Demonstration How is it going? –Ozone is measured in the summer –Goal is <85ppm in 08 Measured94ppm03 Measured89ppm04 Modeledtbd08 Modeled80ppm09

9 9 Attainment Demonstration What does it mean? –It looks like we will be able to show attainment of the Federal ozone standard without adding new air pollution programs beyond what are already planned Federal control measures –Cleaner vehicles –Cleaner fuels –NOx SIP Call/Clean Air Interstate Rule State control measures –Better auto emissions testing procedure –Expanded auto emissions testing –Clean Smokestacks Act

10 10 Attainment Demonstration Timeline Summer 2005: Modeling results Fall 2005: Strategies (if needed) Spring 2006: Public hearings Fall 2006: Environmental Management Commission (EMC) approval Early 2007: Legislative review June 2007: Due to EPA

11 11 Redesignation Request Process that DAQ will undertake when actual measurement of the air shows it meets the Federal standard Why is it important? –Remove nonattainment label –Remove new source review (NSR)

12 12 AQ Monitor Network Overview

13 13 Current Ozone Values (Standard is less than 85 ppm) County average average Durham8986 Franklin9088 Granville9489 Person9187 Wake9288

14 14 Future: Potential Developments When we get through this current process, we cannot declare victory and go home … Growth assumptions may change Science may change –EPA is now reviewing ozone and PM standards Sept 2006: Fine particles Dec 2007: Ozone

15 15 Local Measures Focus on major emission sources Reduction in vehicle miles traveled Nonroad engines –Generators, construction equipment, lawnmowers, etc. Fleet turnover Alternative fuels Diesel retrofit, anti-idling policies Growth management Episodic controls

16 16 What do you need to take away from this … We think we will be able to show that our air will meet standards in 08 with our existing environmental programs We think the air will actually be under the standard this summer or next Be happy, but remember things may change in the future
