§ 128.21. St. Joe Resources Company; Potter Township, Beaver County, Pennsylvania.
(a) This section applies to the St. Joe Resources Company located in Potter Township, Beaver County, Pennsylvania, which includes the Coal Boiler # 1, Coal Boiler # 2, Sinter Machines (3) and the Roaster Plant (No. 9 Roaster or its equivalent).
(b) The sources identified in subsection (a) as Coal Boiler # 1 and Coal Boiler # 2 shall be relieved from compliance with the applicable requirements of § 123.22(d) (relating to combustion units) when in compliance with this section.
(c) The sources identified in subsection (a) as Sinter Machines (3) and Roaster Plant (No. 9 Roaster or its equivalent) may not emit sulfur dioxide in excess of 2,050 pounds per hour.
(d) The owner or operator may not cause or permit the emission of sulfur dioxide from the sources identified in subsection (a) as Coal Boiler # 1 and Coal Boiler # 2 in excess of all the following:
(1) 1.2 pounds SO2/million Btu maximum daily average.
(2) 1,175 pounds SO2 per hour, whichever is more restrictive.
(e) The owner or operator may not emit sulfur dioxide from the combination of sources identified in subsection (a) in excess of 3,127 pounds SO2/hour.
(f) The owner or operator may not emit sulfur dioxide from sources identified in subsection (a) in excess of the quantities calculated by the following equations when determined on a 7-day running basis except for a period up to 45 continuous days during calendar year for annual maintenance outage on the Roaster Plant and Sinter Machines (3):
Ea = A1B1 + A2B2 + 1.65x10-7 A3B3 + 2A4B4
Eb = 1.7 B10.86H10.14 + 1.7 B20.86H20.14 + 8.25x10-5B3 + 0.054B4
where Ea = The combined actual emission rate for the sources listed in subsection (a) in pounds SO2 per day.
Eb = The combined allowable emission rate as specified in Chapter 123 (relating to standards for contaminants) for the sources listed in subsection (a) in pounds SO2 per day.
A1 = The actual emission rate in pounds SO2 per million Btu for coal boiler # 1.
A2 = The actual emission rate in pounds SO2 per million Btu for coal boiler # 2.
A3 = The actual SO2 emission rate in parts per million volume (dry basis) for the roaster plant.
A4 = The actual sulfur content expressed as a decimal fraction by weight of the calcine and zinc scrap consumed in the sinter machines.
B1 = The actual heat input in millions Btu per day for coal boiler # 1.
B2 = The actual heat input in millions Btu per day for coal boiler # 2.
B3 = The actual volumetric gas flow rate in dry standard cubic feet per day for the roaster plant.
B4 = The actual calcine consumption rate in pounds per day plus the zinc scrap consumption rate in pounds per day for the sinter machines.
H1 = The actual hours of operation per day for coal boiler # 1.
H2 = The actual hours of operation per day for coal boiler # 2.
