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.

				  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),

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.
