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.
