KANSAS CITY, KANSAS; MISSOURI

Effective Redesignation Date: 7/23/92 (57 FR 27939, 6/23/92)

Maintenance Plan - Key Features

• 1988 base year, emissions budget through 2010
• maintain RVP of 7.8 psi
• Phase II volatility restrictions

Contingency Plan Trigger

• increase in VOC emissions which exceeds the "action line" level (encroaching into the emission margin of safety), but does not result in ozone violations
• violation of the ozone NAAQS

Contingency Measures

• VOC emissions offsets for new and modified stationary sources
• transportation control measures
• Stage II
• I/M program
• VOC controls on minor new sources
• RACT for sources covered by new EPA CTG documents

Schedule

• select, adopt, and implement measure before next ozone season

A violation has occurred in: Kansas City, Kansas-Missouri

Violation occurred on 7/13/95 at Missouri, Liberty monitor.

Actions - Information as of 10/18/95

- On 7/24/95, Region VII met with Air Quality Forum (state, local, and planning agencies). Kansas reluctant to speak, preferred to call violation an "exceptional event."

- On 7/28/95, the State of Missouri sent letter to Region VII; proposed to choose appropriate contingency measures that differ from ones specified in the original maintenance plan, such as:

• lower RVP (7.0 or 7.2 psi)
• reformulated gas (currently attainment areas cannot opt into reformulated gas programs; OMS plans to look into policy options allowing this).

- EPA suggested implementation of control measure(s) prior to next ozone season (4/1/96 to 9/15/96).

- Region VII responded on 8/17/95 to the letter from Missouri.

- On 8/28/95, Region VII met again with State and local representatives.

• Agreement by group to perform spot VOC modeling to determine where emissions are coming from and best location of controls
• Tried to select criteria to go into MOBILE model
• Will have VOC information by November 1995.

- EPA told representatives that they can substitute an equivalent contingency measure, i.e., one that gets similar reductions. However, Region VII wants more guidance as to what criteria to use to determine the adequacy of a contingency measure.

- EPA wants to get RACT rules (e.g., for bakeries and another source category) on the books before next ozone season and wants to include any additional Missouri sources since 1992.

Actions - Information as of 9/20/96

- Region VII met with local planning committee to get input on which contingency measures to use. The measures being considered include: I/M, lower RVP gasoline (7.0), clean fuel fleets, no fare transit, further evaluation of point sources for RACT, and public education campaign.

- Workgroups have been established to examine feasibility and strategies for each recommended measure.

- Review of 1994 - 1996 data shows the area is no longer violating. However, the Region is encouraging the state to continue to look at the need for additional measures and to replace the contingency measures that were originally listed in the maintenance plan.
