Universal Citation: MN Rules 7011.1405

Current through Register Vol. 49, No. 13, September 23, 2024

Subpart 1. Fluid catalytic cracking unit catalyst regenerator and incinerator-waste heat boiler.

No owner or operator of an existing fluid catalytic cracking unit catalyst regenerator or its incinerator-waste heat boiler at a petroleum refinery shall allow to be discharged into the atmosphere from the regenerator or its incinerator-waste heat boiler any gases that:

A. contain filterable particulate matter in excess of 10.0 lb/1000 lb (10.0 kg/1000 kg) of coke burn-off in the catalyst regenerator; or

B. exhibit greater than 30 percent opacity, except that 30 percent opacity may be exceeded for one six-minute period in any one-hour period. An exceedance of this opacity standard occurs whenever any one-hour period contains two or more six-minute periods during which the average opacity exceeds 30 percent.

If auxiliary liquid or solid fossil fuels are burned in the fluid catalytic cracking unit incinerator-waste heat boiler, particulate matter in excess of that permitted by item A may be emitted provided that the incremental rate of particulate emissions shall not exceed 0.4 pounds per million Btu (0.72 grams per million cal) of heat input attributable to such liquid or solid fossil fuel.

Subp. 2. Fuel gas combustion device and indirect heating equipment.

Flares subject to the conditions of Code of Federal Regulations, title 40, part 60, subpart Ja, are not subject to the limits of this subpart. No owner or operator of existing fuel gas combustion devices and indirect heating equipment at a petroleum refinery shall cause to be discharged into the atmosphere from such devices and equipment any gases which contain sulfur dioxide in excess of 1.75 pounds per million Btu (3.15 grams per million cal) heat input. The total emissions of sulfur dioxide from all existing fuel gas combustion devices and all indirect heating equipment shall be divided by the total heat input of all such devices and equipment to determine compliance with this section; provided that no owner or operator shall cause to be discharged from any one fuel gas combustion device or any one unit of indirect heating equipment any gases which contain sulfur dioxide in excess of 3.0 pounds per million Btu (5.4 grams per million cal) heat input.

Subp. 3. Indirect heating equipment.

The standards of performance in parts 7011.0500 to 7011.0530 for indirect heating equipment do not apply to indirect heating equipment at a petroleum refinery. Only the standards of performance for indirect heating equipment in this part apply to indirect heating equipment. No owner or operator of existing indirect heating equipment at a petroleum refinery shall allow to be discharged into the atmosphere from the equipment any gases that:

A. contain filterable particulate matter in excess of 0.4 pounds per million Btu (0.72 grams per million cal) heat input; or

B. exhibit greater than 20 percent opacity, except for one six-minute period per hour of not more than 60 percent opacity. An exceedance of this opacity standard occurs whenever any one-hour period contains two or more six-minute periods during which the average opacity exceeds 20 percent or whenever any one-hour period contains one or more six-minute periods during which the average opacity exceeds 60 percent.

Subp. 4. Definition.

For the purposes of this part, "existing" means equipment on which construction, modification, or reconstruction did not commence after June 11, 1973.
