APCD Multipollutant Stakeholder Group

The APCD's Multipollutant Stakeholder Group (MPSG) was a community stakeholder group that was convened in late 2019 to develop strategies to reduce air pollution in Louisville.

This group was formed in late 2019 to discuss current air pollution challenges and determine our community’s next steps to improve local air quality and reduce health impacts from air pollution. The group discussed some Louisville's most pressing air pollution issues, including ground-level ozone, fine particle pollution, and air toxics.

The group brought together business officials from key sectors, community leaders, and relevant government, academia, and health representatives. The MPSG met several times—as a full group and in subject-specific committees—in late 2019 and early 2020. Participants looked at current air quality data, modelling, and regulatory requirements (in particular, the 2015 8-hour Ozone standard NAAQS requirements) to develop a common baseline understanding among the stakeholders.

The MPSG was informed by the work of five committees – Point Source, Area Source, Mobile Source, Health, and Outreach/Education. Examples of the committee work included 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.

The APCD will use emission reduction recommendations in the Final Multipollutant Stakeholder Group Report 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 may be provided to other relevant entities or agencies where possible.
