1. (1) Class 1 Counties: No person shall cause or permit the emission of particulate matter from fuel-burning equipment in a Class 1 County in excess of the amount shown in Table 4-1 for the heat input allocated to such source. For sources in Class 1 Counties, interpolation of the data in Table 4-1 for heat input values between 10 million BTU/hr and 250 million BTU/hr shall be accomplished by the use of the equation:

   E = 1.38H^-0.44

   where:

   E = Emissions in lb/million BTU

   H = Heat Input in millions of BTU/hr

2. (2) Class 2 Counties: No person shall cause or permit the emission of particulate matter from fuel-burning equipment in a Class 2 County in excess of the amount shown in Table 4-1 for the heat input allocated to such source. For sources in Class 2 Counties, interpolation of the data in Table 4-1 for heat input values between 10 million BTU/hr and 250 million BTU/hr shall be accomplished by the use of the equation:

   E = 3.109H^-0.589

   where:

   E = Emissions in lb/million BTU

   H = Heat Input in millions of BTU/hr

3. (3) For purposes of this Rule, the total heat input from all similar fuel combustion units which discharge particulate matter through a common stack at a plant or premises shall be used for determining the maximum allowable emission of particulate matter.

4. (4) New fuel-burning sources emitting particulate matter shall be subject to the rules and regulations for Class 1 Counties, paragraph (1) of this Rule, regardless of their location.

   Table 4-1 Allowable Particulate Matter Emission Based on Heat Input

5. (5) In lieu of the particulate emission limitations contained in paragraph (1) of this Rule for existing coal fired boilers at pulp mills in Talladega County having a rated capacity of up to 300 million BTU per hour, the allowable particulate emission limit shall be 0.1 lb/MMBTU.
