STAR Regulation 5.30 Technical Information

STAR Program: Strategic Toxic Air ReductionThe STAR 5.30 Stakeholder Group began its work in July 2006 and reached consensus on the Report and Plan of Action at its last meeting in August 2007.

Chemicals of Concern

Regulation 5.30 requires that the Report and Plan of Action assess and address the risk to human health and welfare from ambient air concentrations of toxic air contaminants from minor stationary, area, mobile and non-road mobile sources. However, the regulation does not identify the contaminants that are to be evaluated. In general, APCD developed chemical profiles for individual source categories. The chemicals identified as being emitted from a source category were then evaluated for potential risk. Regulation 5.23 contains a complete list of toxic air contaminants

Source Categories of Concern

Minor and Area Sources

Published July 19, 1999, the EPA’s Integrated Urban Strategy (64 FR 38706) included a list of 70 toxic air contaminant emitting area source categories. To date, standards have been promulgated for 15 area source categories; 55 source categories remain to be addressed. Of the 70 categories identified for listing, only 16 area source categories (listed below) are represented in Louisville.

  • Dry cleaning facilities
  • Municipal landfills
  • Portland cement
  • Publicly owned treatment works
  • Stationary internal combustion engines
  • Hospital sterilizers
  • Gasoline distribution Stage I
  • Industrial boilers
  • Paint and allied products
  • Plastic parts and products (surface coating)
  • Clay ceramics manufacturing
  • Auto body refinishing
  • Institutional/commercial heaters
  • Miscellaneous organic chemical manufacturing
  • Industrial organic chemicals manufacturing
  • Synthetic rubber manufacturing

If the District becomes aware of sources in Louisville in the remaining source categories, the District would perform a similar review of this additional area source category.

Mobile and Non-road Mobile Sources

There are two categories of mobile sources of air pollution:

  • On-road mobile sources are cars and trucks designed to operate on streets and highways. The phrase "mobile sources" has often been used to refer specifically to such vehicles.
  • Non-road mobile sources are (durable) air pollution sources that can move or be readily be moved, including aircraft, trains, ships and boats, construction equipment, agricultural and lawn care equipment, portable generators and other equipment.

STAR Regulation 5.30 Stakeholder Group Report and Plan of Action

The STAR 5.30 Stakeholder Group Report and Plan of Action documents the STAR Regulation 5.30 process from beginning to end. The group reached consensus 35 recommendations to reduce risk from toxic air pollution (see Section 14), which were presented to the Air Pollution Control Board on September 19, 2007.

Hot Spots Monitoring

This report summarizes the results and the methodology for the Hot Spots monitoring project conducted by APCD. Analysis included reviewing the data results from the samples provided by Air Toxics Ltd., the meteorological data collected by APCD, and preparing visual summaries and comparisons of the data results. The purpose of the study was to identify findings and observations that were most significant and to help shape and direct the future toxics monitoring plan for Louisville Metro.

Risk Analysis Summary

The Risk Analysis Summary is a table summary of the results of risk modeling and analysis. The risk modeling included estimates of the current level of risk from a source and the level of risk that could be achieved through the implementation of reasonable risk-reduction measures.

Voluntary Programs and Grants

The following is a compilation of programs administered by the EPA that encourage voluntary activities aimed at reducing air pollution. These programs can be applied in our community to reduce the risk associated with toxics emissions. A number of these programs are focused on a specific source sector, while others have a broad, community-wide scope. Some programs provide grants to help recipients initiate these activities in their own communities while others seek to form partnerships or create clearinghouses of information. There are a myriad of opportunities for collaboration and partnership among different sectors of our community in the implementation of these programs; including government, private, and non-profit groups.
