Explanatory Notes:

[1] Includes any unique chemical substance that contains the listed metal as part of that chemical's infrastructure, excluding barium sulfate. Barium sulfate has been delisted as a toxic air pollutant and should not be included as part of the metals and compounds emissions. Concentrations are based on [MICRO]g (x)/m3, where x is the elemental form of the metal.
[2] Includes only 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), and octachlorodibenzo-p-dioxin (OCDD).
[3] Includes all isomers of chlorinated dibenzo-furans.
[4] Includes o-, m-, and p-cresol, and mixed isomers.
[5] Includes 2,4- and 2,6-dinitrotoluene and mixed isomers.
[6] Glycol ethers refers to the following compounds:

Ethylene glycol monomethyl ether (CAS Number 109864)

Ethylene glycol monomethyl ether acetate (CAS Number 110496)

Ethylene glycol monoethyl ether (CAS Number 110805)

Ethylene glycol monoethyl ether acetate (CAS Number 111159)

Diethylene glycol dimethyl ether (CAS Number 111966)

Ethylene glycol dimethyl ether (CAS Number 110714)

[7] Includes organic compounds with more than one fused benzene ring and which have a boiling point greater than or equal to 100°C. Those compounds listed as Naphthalene and Methylnaphthalene are not to be included as PAHs for the purposes of this regulation.
[8] Includes toluene-2,4- and 2,6-diisocyanate and mixed isomers.
[9] Includes o-, m-, and p-xylene, and mixed isomers.
[10] Excludes soil or foliar application of ammonia in agricultural practices.
[11] Includes the following compounds: Naphthalene (CAS Number 91-20-3), Methylnaphthalene (CAS Number 1321-94-4), 1-Methylnaphthalene (CAS Number 90-12-0), 2-Methylnaphthalene (CAS Number 91-57-6).
[12] Zinc chromates and zinc arsenates are Class I TAPs regulated as carcinogens under Chromium VI (and compounds) and arsenic (and compounds) TAP categories.

Explanatory Notes:

* For pollutants listed in Table 51.3 of this Section, minimum emission rates and ambient air standards have not been established. Certain requirements of this Subchapter do not apply to these pollutants. For example, the provisions of LAC 33:III.5109, MACT and Ambient Air Standard Requirements and Standard Operating Procedure requirements, do not apply. Emissions of Table 51.3 pollutants shall not be counted toward a facility's total toxic air pollutant emissions in determining whether a stationary source is a major source for the purposes of this Subchapter. The provisions of LAC 33:III.5107.A, B, and C, Reporting Requirements and Availability of Information, do apply to emissions of Table 51.3 pollutants. Such emissions shall be reported on the Annual Emissions Reports provided for under LAC 33:III.5107.A.1 and 2, beginning with the report due July 1, 1993. To determine the applicability of other provisions to the pollutants listed in this table, refer to the text of this Subchapter.

[1] Coke manufacturers to which the reporting requirements of this Subchapter apply should report emissions of listed Louisiana toxic air pollutants in the same format used by all other affected major sources in the state.
[2] Includes mineral fiber emissions from facilities manufacturing or processing glass, rock, or slag fibers (or other mineral derived fibers) of average diameter 1 micrometer or less.
[3] Excludes those glycol ethers listed in Table 51.2 of this Section. Those glycol ethers listed in Table 51.2 of this Section are subject to all provisions of this Subchapter. Includes any other mono- and di-ethers of ethylene glycol, diethylene glycol, and triethylene glycol R(OCH2CH2)n-OR'

where:

n = 1, 2, or 3;

R = alkyl or aryl groups;

R' = R, H, or groups which, when removed, yield glycol ethers with the structure: R(OCH2CH)n-OH. Polymers are excluded from the glycol category.

[4] X'CN where X = H' or any group where a formal dissociation may occur. For example KCN or Ca(CN)2.
