Kansas City Ozone Update

March 2008 Kansas Air Quality Seminar

Presented by Thomas Gross

slide3

Overview

  • Ground Level Ozone
  • KC Region Ozone History
  • Current Status - Violation
  • 8-hour Ozone Maintenance Plan
  • Contingency Measures
  • Future Activities

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide4

Ozone Primer

  • Identical to upper atmosphere ozone
  • Caused by reaction of volatile organic chemicals (VOCs) and oxides of nitrogen (NOx)
  • Highest when conditions are hot, sunny and calm
  • VOCs and NOx emitted by cars, trucks, small businesses, utilities & large industry
  • Can trigger breathing problems, especially in those with respiratory conditions

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide5

Causes of KC Ozone

  • Natural background levels
  • Transport
  • Homegrown
  • Other factors
      • Clean Air Interstate rule
      • Tier 2 Vehicle and fuels rule
      • Heavy Duty Diesel rule
      • Regional Haze rule
      • Voluntary programs
      • Flint Hills burning

Our Vision – Healthy Kansans living in safe and sustainable environments.

8-Hour Ozone Standard

  • 2003 - EPA transitioned from 1-hour to 8-hour standard
  • NAAQS 8-hour standard = 0.08 ppm (80 ppb)
    • Due to rounding EPA allows up to 84 ppb
  • Design value
    • Worst monitor in planning area
    • Based on a rolling three-year average
  • To meet standard, the design value must be lower than 85 ppb

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide9

KC Region Ozone History

  • From mid-1970s through early 1990s, KC did not meet 1-hour ozone standard
  • In 1992, area was redesignated attainment for 1-hour ozone standard
  • Area violated 1 hour standard in mid-1990s
  • Area has met the 1-hour standard in recent years

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide10

KC Region Ozone History

  • KC designated “unclassifiable” in June 2004
    • Result of Flint Hills burning
  • KC designated “attainment” in June 2005
    • fluke of weather – record cool summer in 2004
  • 2005 & 2006 ozone seasons were high

Our Vision – Healthy Kansans living in safe and sustainable environments.

Effectiveness of Controls

Estimated location of highest

8-hr ozone concentration

slide15

So what are we doing to fix the problem?

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide16

Clean Air Action Plan

  • Coordinated by MARC
  • Developed in 2004
  • Comprehensive voluntary plan for reducing emissions
  • Targets both stationary and mobile sources
  • Short, intermediate and long-term measures

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide17

Area Source ReductionPrograms

  • Solvent metal cleaning rule
  • Technical Seminars
      • Lawn and Garden
      • Printing
      • Painting
      • Solvent metal cleaning

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide18

Mobile Source Reduction Programs

  • Low RVP gasoline
  • Gasoline tank truck vapor testing
  • Ozone alerts
  • Bus RideShare
  • Gas cap testing programs
  • Employee carpool incentive program
  • AirQ workplace initiative
  • Idle reduction seminars

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide19

EPA Regulatory Options

  • Maintenance Plan
  • SIP Call
  • Nonattainment Designation
  • Curtails economic development
  • Less flexibility in selecting control options
  • Transportation plan conformity with SIP
  • Potential sanctions for failure to meet standard
  • AND a bunch of additional work for KDHE

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide20

What Happened?

  • KDHE developed Maintenance Plan
  • EPA approved the plan
  • KC violated the 8-hour ozone standard on June 15, 2007
  • Triggered contingency measures in the plan
  • EPA agreed to allow implementation of the plan

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide21

What now?

  • Implementation of Maintenance Plan’s Phase I contingency Measures
    • Heavy duty diesel idle reduction rule
    • Large NOx source emission reductions
  • Maintenance Plan includes additional measures if air quality does not improve
    • Phase II menu of options
    • Includes triggers for implementation

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide22

Phase I - Contingency Measures

  • Kansas – Phase I
    • Idle Reduction Rule
    • NOx RACT rule for point sources > 1000 tons of actual emissions per year
      • Boilers
      • Furnaces
  • Missouri – Phase I
    • Idle reduction rule
    • NOx RACT rule for point sources >1000 tons of actual emissions per year (CAIR)

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide23

Idle Reduction Rule

  • In Kansas & Missouri
  • Commercial, public and institutional heavy-duty diesel vehicles
    • Idle no more than 5 minutes in any 60 minute period
    • Exceptions
  • Load/Unload locations
    • shall cause no vehicles covered by this regulation to idle for a period greater than 30 minutes in any 60 minute period

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide24

NOx Emission Limits

  • Coal fired boilers
    • NOx emission rate of

0.23 lb/MMBtu

  • Furnace – flat glass
    • NOx emission rate of

7.0 lb/ton glass produced

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide25

Time Frame for Phase 1 Controls

  • Violation occurred during the 2007 ozone season
  • EPA letter to states validating data on September 12, 2007
  • States begin regulation implementation
    • Idle rule and NOx rule under review
  • EPA target for implementation of controls is 24 months after EPA letter

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide26

Phase II – Triggers

  • Phase II contingency measures triggered if:
    • Three consecutive years exceeding 84 ppb
    • Single three-year design value of 89 ppb
    • Investigate any three-year design value over 84 ppb

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide27

Potential Phase II Control Measures

  • NOx RACT rule for point sources >100 tons per year
  • NOx RACT rule for large NOx sources (>1000 tons) in Miami and Linn Counties
  • Open burning restrictions
  • Lower threshold for VOC RACT rules to 75 tons per year
  • VOC control for Architectural and Industrial Maintenance Coatings
  • Diesel Engine Chip Re-flash regulation

Our Vision – Healthy Kansans living in safe and sustainable environments.

slide28

Future Plans for KC

  • Implement Phase I contingency measures in Johnson and Wyandotte Counties.
  • Implement voluntary emission reduction programs
  • Continue to evaluate Phase II controls
    • Effectiveness
    • Timely
    • Cost
