June 5, 2013
John Lyons, DirectorKentucky Division for Air Quality
To Protect and Enhance Kentucky’s Environment
Topics Covered• Air Quality Trends
• Non-attainment Status
• Near Road Monitoring
• Mercury and Air Toxics Standards
• Air Toxics and Permitting
2
National Ambient Air Quality Standards• National Ambient Air Quality Standards (NAAQS) are set
for six widespread and common Criteria Pollutants• Particulate Matter• Ozone• Lead• Sulfur Dioxide• Nitrogen Oxides• Carbon Monoxide
• Section 109 of CAA: EPA shall propose regulations prescribing a NAAQS for each criteria pollutant
• These standards shall be based on a margin of safety adequate for protecting public health

NAAQS Review & Setting of New Standards
• The CAA requires NAAQS to be reviewed at 5 year intervals & revised as deemed necessary
• Reviewing the NAAQS is a lengthy undertaking and includes several major phases
• Planning• Science Assessment• Risk/Exposure Assessment• Policy Assessment• Rulemaking
7
Designation Process• When a new standard is set:
– States have 1 year to make designation recommendations to EPA based on
• Air quality data• Emissions data• Level of control of emission sources• Population density and degree of urbanization• Traffic and commuting patterns• Growth rate and patterns• Meteorology• Geography/topography • Jurisdictional boundaries
– EPA has 1 year to review state designation recommendations, modify the recommendations if necessary, and make final attainment/nonattainment area designations
8
State Implementation Plans• Clean Air Act requires states to create a specific plan to
achieve the NAAQS for each area designated nonattainment
• A State Implementation Plan (SIP) is an air quality plan that shows how to attain or maintain the NAAQS and bring an area back into attainment
• Each state is responsible for developing SIPs to demonstrate how standards will be achieved, maintained, and enforced
• Plans provide for the implementation and enforcement of emission control measures from all source categories
9
Attainment of the NAAQS
10
establishes every 5 years if deemed appropriate
1 year 1 year 3 years 2 years
Attainment Status
11
Nonattainment (partial county) – 2008 8-hour ozone Nonattainment (whole county) – 2006 PM2.5
Attainment
Near Road Monitoring• February 9, 2010 – EPA finalizes requirements for
new 1-hour NO2 standard.
• NO2 is a large component of mobile emissions
• Near road site location
• Core-based statistical area with population >500,000
• Site operational by January 1, 2014
• Site operated by LMAPCD
12
Proposed Jefferson Co. Site• Aerial photo of proposed site location – 1517 Durrett Lane, 0.90 miles north of the
I-264/I-65 interchange.
13
Mercury and Air Toxics Standard• Rule became effective on April 16, 2012
• Existing sources have 3 years to comply unless granted an extension
• New sources would have to comply upon startup
• Rule expected to reduce mercury emissions by 90%
• Other pollutants such as SO3 required to be controlled as well
• Multiple lawsuits have been filed on the rule
14
Air Toxics and Permitting• State has a different program than LMAPCD
• Broadly governed under one regulation – 401 KAR 63:020
• Requires screening of air toxics, up to and including a formal risk assessment
• Has been in place since 2006
