Section 20.2.31.110 - EXISTING EQUIPMENT

A. The owner or operator of existing coal burning equipment shall not permit, cause, suffer or allow sulfur dioxide emissions to the atmosphere in excess of 28 percent on or after December 31, 1981 of that which is produced by the coal burning equipment averaged over any thirty-day period, if such coal burning equipment has a rated heat capacity greater than 3,000 million British Thermal Units per hour (higher heating value) and less than or equal to 5,000 million British Thermal Units per hour (higher heating value).

B. After December 31, 1984, The owner or operator of a coal burning station consisting of two or more units of existing coal burning equipment having a rated heat capacity greater than 250 million British Thermal Units per hour (higher heating value) shall not permit, cause, suffer or allow sulfur dioxide emissions to the atmosphere:

(1) In excess of 28 percent of that which is produced by such existing coal burning equipment, averaged over any thirty-day period, determined on a total station basis; or

(2) More than once per year, total sulfur dioxide emissions in excess of 17,900 pounds per hour, averaged over any three-hour period, determined on a total station basis.

C. Prior to December 31, 1984, the owner or operator of an existing coal burning station consisting of two or more units of existing coal burning equipment shall submit to the Department individual stack emission limitations expressed in pounds per hour for all stacks from which flue gases are released from existing coal burning equipment of the station such that total sulfur dioxide emissions from the station do not exceed 17,900 pounds per hour. Upon request of the owner or operator of an existing coal burning station, the Department may later approve alternative individual emission limitations for each stack serving existing coal burning equipment of the station as long as the total of the individual stack emission limitations from the station do not exceed 17,900 pounds per hour, averaged over any three-hour period. Until alternative individual stack emission limitations are approved by the Department, the previously approved individual emission limitations shall remain in effect.
