Mike Abraczinskas, Deputy Director North Carolina Division of Air Quality
Mecklenburg County Air Quality Forum November 7, 2013
Overview
• DENR / DAQ
• Success! Update on Ambient Air Quality in NC
• Challenges / Priority issues
– New monitoring
– Biomass

DENR - Mission
• Protect NC’s environment and natural resources
• Fundamental principles:
– Be a resource of invaluable public assistance
– Consider cost/benefit analyses in doing our work
– Consider - with respect and understanding – input from
legitimate, diverse and thoughtful perspectives
• Outcome:
– A collaborative stewardship among the citizens, government
regulators and the business community will maintain and
enhance North Carolina's environment and natural resources for the benefit and enjoyment of everyone living in or visiting our great state.
DAQ Mission
• Work with the state's citizens to protect and improve
outdoor, or ambient, air quality in North Carolina for the
health, benefit and economic well-being of all.
• To carry out this mission, the DAQ has programs to:
– operate a statewide air quality monitoring network to measurethe level of pollutants in the outdoor air
– develop and implement plans to meet future air quality initiatives – assure compliance with air quality rules
– educate, inform and assist the public with regard to air quality

Success !!!
• Air Quality in NC continues to improve!
• Standards and goals set a decade ago have been met!
1997 Ozone standard 1997 Fine particle standard 2006 Lead standard
2010 Nitrogen dioxide standard 2010 Sulfur dioxide standard 2012 Fine particle standard
2008 ozone standard - work to do in Charlotte. 201415 ozone standard

On the right track!

Challenge – Near Road Monitoring
– Required by EPA’s NO2 - Jan 2010
– Initial rule required four sites by Jan 2013
• Charlotte, Raleigh, Greensboro, and Durham – Later modified due to funding issues
• Charlotte and Raleigh by Jan 2014 • Others in 2017 (if ever)
– Has since added additional required pollutants • CO and PM2.5 by Jan 2017
Challenge – Near Road Monitoring
• NO2 monitor must be within 50 meters of roadway
• Roadway must be among highest traffic levels
– Based on AADT
(annual average daily traffic)
– Extra weighting for
heavy-duty trucks
– Focus on peak NO2
concentration
• Safety concerns
– Motorists and our

Near Road Monitoring - Concerns
• No issue with a near-road research project
– But a regulatory monitor creates anxiety!
• EPA has not provided any insight or guidance on the
potential consequences of near road monitors showing
nonattainment
• Potential problems
– State has no authority to implement the necessary
control measures
• We already have vehicle emission inspections and
transportation conformity in place.
– What size nonattainment area will be designated?
– Mandatory control measures that will do nothing to
Near Road Monitoring - Concerns
• Need three full years of monitoring data, 2014-2016 to
compare to the ambient NO2 standard
• So we won’t know if we have an issue until early 2017.
Then what ???
• If the NO2 monitors meet standard, nothing.
• If they violate …
13
Biomass
• ~12 permit applications per year (recently)
– Wood fired boilers and wood pellet manufacturers• Biomass deferral rule vacated – July 12, 2013
• The effective date (i.e. mandate) of the vacatur of the
biomass deferral rule is not yet known.
15
Biomass Boilers
• Court decision vacating the biomass deferral rule
• Senate Bill 3 BACT
A key requirement of Senate Bill 3 is “Any new biomass
renewable energy facility that delivers electric power to
an electric power supplier shall meet BACT.”
Wood Pellet Manufacturing Facility Issues
• Court decision vacating the biomass deferral rule
• PSD or not? Emissions from pellet manufacturing may
be much higher than initially estimated.
– Recent testing in GA found significant amounts of VOCs coming not only from the dryers (where VOCs were controlled by thermal oxiders), but also from the pellet coolers and hammermills.
– After additional testing, VOC emissions were estimated to be 1300 TPY.
• Debate over environmental costs associated with pellet
manufacturing
17
Solid waste… or not?
• On August 7, 2013, the EPA promulgated revisions to the
Commercial/Industrial Solid Waste Incinerators (CISWI) regulations and the Solid Wastes Used as Fuels or Ingredients in Combustion Units rule (also known as the NHSM rule).
• Boiler or Incinerator ?
• 12-14 NHSM determinations per year involving materials like landfill
gas, swine gas and poultry litter.
• Key issues in NHSM Determinations include:
Demonstrating the material is managed as a valuable commodity. Demonstrating the material has meaningful heat content.
Demonstrating that the contaminants in the material are

Rule Changes – Vehicle Emissions Inspections
• Session Law 2011-145:
– DAQ and DMV Study: exempting new vehicles
would not have a negative impact on air quality.
– Exempting new vehicles slightly increases
emissions (…according to EPA’s mobile emissions
model)
– But !!! Compliance rates are actually higher since
the electronic authorization program was
implemented.
– Using the higher compliance rates in the State
Implementation Plan (SIP) more than offsets the
very slight projected increases in emissions from
the exemption.
Rule Changes – Vehicle Emissions Inspections
• Session Law 2012-199:
– Exempts 3 most recent model year vehicles with
less than 70,000 miles
– Rule changes necessary
– Effective on the later of:
• January 1, 2014; or
• Month after SIP amendment is approved and DMV’s Motor
21
Rule Changes – Vehicle Emissions Inspections
• Comment period ended October 14, 2013.
• Summary of comments:
– Only savings are for newer car owners
– From inspection station owners: requests and suggestions to reduce
uncertainty in implementation of the exemption
– Questions about applicability of the program at federal installations.
• Rule goes to Environmental Management Commission
on November 14, 2013 for approval.

Air Toxics – 2 years and counting…
• Sept/Oct 2011 - Environmental Review Commission (ERC)
meetings
• Oct 2011-Apr 2012 - Working group • May 2012 - Bill introduced, HB 952
• June 28, 2012 - Became law, SL 2012-91
• Sept. 25, 2012 - Meeting with interested parties
• December 1, 2012 - Report w/ recommendations submitted to ERC • March 20, 2013 - Stakeholder Meeting on Draft Rule incorporating
recommendations
• July 11, 2013 –Requested of EMC to Proceed to Hearing on Draft
Rules
Air Toxics – Summary of SL 2012-91
Section 1
– Exempts sources subject to certain federal regulations – Codifies “Director’s Call” provision
Section 2
– Requires rule amendments consistent w/ Section 1
Section 3
– Requires review of existing rules and their implementation
Section 4
25
Air Toxics – Section 3
• Requires DAQ to review the State air toxics rules and
their implementation to determine whether changes
could:
– Reduce unnecessary regulatory burden
– Increase the efficient use of DAQ resources while
maintaining protection of public health
• Conduct the review in consultation with interested
parties
• Report the results of the review and include
recommendations to the ERC by 12/1/12
Recommendations for Rule Changes
1. Develop an additional set of emissions
thresholds for pollutants coming from
unobstructed vertical stacks
2. Exempt natural gas and propane fired boilers
3. Exempt emergency engines
4. Eliminate SIC call
5. Clarify use of actual rate of emissions
27
Air Toxics – comments
• 44 Commenters
(Individual citizens, environmental groups, regulated community)– EMC should adopt the proposed rule amendments
– EMC should not adopt the proposed rule amendments
– DAQ is misinterpreting S.L. 2012-91
– DAQ should not model all exempt sources
– DAQ should define unacceptable risk
– DAQ should hold more public hearings
• DAQ currently reviewing and developing responses to
comments
• Hearing Officer’s Report scheduled for January 9, 2014
EMC meeting.

Challenges – Shale Gas
Challenges – Shale Gas
• Session Law 2012-143 (Senate Bill 820)
• Mining and Energy Commission, Environmental Management Commission, Public Health Commission • Develop a modern regulatory program for horizontal drilling and hydraulic
31
Shale Gas & Air Quality
• Understanding air emission sources and pollutant
profiles
• Reviewing regulatory framework
– New regulations are not needed.• Air Permitting and Compliance
– Understanding the processes, sources and emissions – Learning from other States
• Emissions Inventories
– What data are available / needed? – Estimate emissions per well site – Estimate air quality impacts
• Ambient Air Quality Monitoring Plan
Just a few more challenges…
Keeping up with litigation:
• Implementation of fine particle standards. • Startup, Shutdown, Malfunction emissions. • Interstate transport.
• Numerous suits related to Federal Standards. • Deferral of designations for Sulfur Dioxide.
• Coming soon: Implementation approach for Sulfur Dioxide.
Emerging Issues:
