APCD Multipollutant Stakeholder Group

Ozone - Louisville's persistent pollutantThe APCD's Multipollutant Stakeholder Group is a community stakeholder group that will develop strategies to reduce air pollution in Louisville.

This group will discuss current air pollution challenges and glean recommendations for our community’s next steps to improve local air quality and reduce health impacts from air pollution. As you may know, Louisville is currently not meeting the recently strengthened 8-hour Ozone National Ambient Air Quality Standard (NAAQS). Although our community has made great progress in reducing overall air pollution, ozone continues to be a major challenge.

The Multipollutant Stakeholder Group (MPSG) will also look at reducing fine particulate pollution and air toxics, which may provide co-benefits to the effort to reduce ozone. This is a departure from our past stakeholder convenings, in which only a single pollutant type was examined, but is in keeping with the current state of air quality planning needs and with our community’s public health goals. 

The group will bring together business officials from key sectors, community leaders, and relevant government, academia, and health representatives. Group members will be asked to participate in stakeholder discussion and asked to select at least one committee in which to participate. The process will begin by convening two sessions of the full MPSG, where current air quality data, modelling, and regulatory requirements (in particular, the 2015 8-hour Ozone standard NAAQS requirements) will be shared and discussed to develop a common baseline understanding among the stakeholders.

We anticipate the group will meet – either as a whole or in subject-specific committees – in twice-monthly two-hour meetings over the next six months. The first meeting will be on Wednesday, November 6, from 3-5 p.m. at the Edison Center, 701 W. Ormsby Ave.

The APCD will use emission reduction recommendations in the creation of a Multipollutant Air Quality Strategy document to guide its work in the coming years, including potential additions to the area’s federally enforceable State Implementation Plan (SIP) if required. Recommendations outside of the scope of the APCD’s work will be provided to other relevant entities or agencies with APCD support where possible.

MPSG Overview

List of Participating Organizations

Committee Participation

Sign up for a committee

The MPSG will be informed by the work of five committees – Point Source, Area Source, Mobile Source, Health, and Outreach/Education. Each committee will have a few initial goals set for its work, but will be encouraged to consider additional goals as needed. Examples of the expected committee work include discussion and development of recommendations for emission reduction strategies, outreach and engagement opportunities around air quality and health impacts, and additional lines of inquiry for how our community can protect public health from air pollution. You are welcome to join these committees and help develop next steps to improve air quality and public health in Louisville.
