TAPs not on the Federal HAP List

The following list of chemicals are toxic air pollutants (TAPs) which are regulated by the Louisiana DEQ, but which are not regulated under the federal Clean Air Act, Title III, Section 112(b) -- Hazardous Air Pollutants (HAPs).  Louisiana's state air toxics regulation is more stringent than the federal regulations, as it also sets an ambient air standard for each of the listed TAPs.  The state list may be found in the Louisiana Administrative Code - LAC 33:III.Chapter 51, Tables 51.1 - 51.3.  To download this regulation, visit the LDEQ Rules and Regulations web page.  With regard to the federal regulations, DEQ has incorporated by reference the federal Maximum Achievable Control Technology (MACT) standards found at 40 CFR Part 63, as well as the original NESHAP standards found at 40 CFR Part 61.
