Ala. Admin. Code r. 335-3-4-.04
Current through Register Vol. 42, No. 8, May 31, 2024
Section 335-3-4-.04 - Process Industries - General(1)Class 1 Counties: No person shall cause or permit the emission of particulate matter in any one hour from any source in a Class I County in excess of the amount shown in Table 4-2 for the process weight per hour allocated to such source. For sources in Class I Counties, interpolation of the data in Table 4-2 for the process weight per hour values up to 60,000 lbs/hr shall be accomplished by use of the equation: E = 3.59 P0.62
(P<30 tons/hr)
and interpolation and extrapolation of the data for process weight per hour values equal to or in excess of 60,000 lbs/hr shall be accomplished by use of the equation:
E = 17.31 P0.16
(P>30 tons/hr)
where E = Emissions in pounds per hour
P = Process weight per hour in tons per hour.
(a) For the existing four (4) sinter machines in Jefferson County, the allowable filterable particulate limit from each windbox exhaust shall not exceed 0.030 grains per dry standard cubic foot with the additional requirement that total filterable particulate emissions from all windbox exhausts and discharge ends not exceed 140 pounds per hour. Compliance with the total emission limit shall be achieved by operating no more than three (3) of the four (4) sinter machines simultaneously.
(2)Class 2 Counties: No person shall cause or permit the emission of particulate matter in any one hour from any source in a Class 2 County in excess of the amount shown in Table 4-2 for the process weight per hour allocated to such source. For sources in Class 2 Counties, interpolation of the data in Table 4-2 for the process weight per hour values up to 60,000 lbs/hr shall be accomplished by use of the equation: E = 4.10 P0.67
(P<30 tons/hr)
and interpolation and extrapolation of the data for process weight per hour values equal to or in excess of 60,000 lbs/hr shall be accomplished by use of the equation:
E = 55.0 P0.11-40
(P> 30 tons/hr)
where: E = Emissions in pounds per hour
P = Process weight per hour in tons per hour.
(3) Where the nature of any process or operation or the design of any equipment is such as to permit more than one interpretation of this Rule, the interpretation that results in the minimum value for allowable emission shall apply.(4) For purposes of this Rule, the total process weight from all similar process units at a plant or premises shall be used for determining the maximum allowable emission of particulate matter that passes through a stack or stacks.(5) New sources subject to this Rule emitting particulate matter shall be subject to the rules and regulations for Class I Counties, contained in paragraph (1) of this Rule, regardless of their location.
