Section 45-7-3 - Emission of Smoke and/or Particulate Matter Prohibited and Standards of Measurement3.1. No person shall cause, suffer, allow or permit emission of smoke and/or particulate matter into the open air from any process source operation which is greater than 20 percent opacity, except as noted in subsections 3.2, 3.3, 3.4, 3.5, 3.6, and 3.7.3.2. The provisions of subsection 3.1 shall not apply to smoke and/or particulate matter emitted from any process source operation which is less than 40 percent opacity for any period or periods aggregating no more than 5 minutes in any 60 minute period.3.4. New By-Product Coke Production Facility. No person shall cause, suffer, allow or permit the emission of smoke and/or particulate matter into the open air in excess of the following provisions from the operation of a new by-product coke production facility, other than a replacement by-product coke production facility that is constructed as per the provisions of subsection 3.3, that begins production after July 1, 1970: 3.4.1. Charging emissions from the charging of any 4 consecutive ovens shall not exceed an aggregate time of more than 60 seconds.3.4.2. Pushing emissions from pushing shall be vented into air pollution control equipment. The particulate matter emissions discharged from this air pollution control equipment shall not exceed a mass emission rate of 0.04 lb/ton of coal charged. The smoke and/or particulate matter emissions discharged from this air pollution control equipment and non-captured pushing emissions shall not exceed 20% opacity.3.4.3. Transport emissions from an enclosed quench car shall not exceed 20% opacity. Transport emissions from an open quench car shall not exceed 10% opacity.3.4.4. Coke side sheds and similar structures used to capture pushing and/or quenching emissions shall be designed and operated so as to prevent the escape of smoke and/or particulate matter emissions from points other than the stack of the air pollution control equipment.3.4.5. Coke oven topside emissions shall not exceed the following: 3.4.5.a. No more than 2% of the charging ports or charging port lids shall have smoke and/or particulate matter emissions excluding the last oven charged.3.4.5.b. No more than 5% of the off take piping shall have smoke and/or particulate matter emissions.3.4.5.c. No smoke and/or particulate matter emissions are permitted from the coke oven gas collector main or any other topside point, except as provided by paragraphs 3.4.5.a and 3.4.5.b.3.4.6. No more than 8% of the door areas of operating coke ovens shall have door area emissions, excluding the door areas representing the last oven charged. Any battery affected by subsection 3.4 shall be constructed in a manner that will allow for the retrofitting of the battery with hooding to capture door emissions and air pollution control equipment designed to at least a 90% particulate control efficiency.3.4.7. Quench towers shall employ, as a minimum, multiple row baffles and use make-up water not to exceed 800 milligrams per liter of total dissolved solids and 100 milligrams per liter of total suspended solids.3.4.8. Smoke and/or particulate matter emissions from combustion stacks shall meet the requirements of subsections 3.1 and 3.2 and shall not exceed a grain loading of 0.025 grains per dry standard cubic foot.3.4.9. Good operating practices must be maintained to prevent the atmospheric entrainment of particulate matter resulting from the spillage or other deposition of coal/coke.3.5. Non-Recovery Coke Production Facility -- No person shall cause, suffer, allow or permit the emission of smoke and/or particulate matter into the open air in excess of the following provisions from the operation of a non-recovery coke production facility:3.5.1. Charging emissions from charging of any 5 consecutive ovens shall not exceed an aggregate time of more than 50 seconds.3.5.2. No more than 2% of the coal charging ports shall have smoke and/or particulate matter emissions.3.5.3. No more than 2% of the coke oven doors. shall have smoke and/or particulate matter emissions excluding the ovens being charged and/or pushed.3.5.4. Pushing emissions shall be vented to air pollution control equipment. The particulate matter emissions from this air pollution control equipment shall not exceed a mass emission rate as determined by the following formula: E=C.09
Where:
E = particulate emission rate in pounds per push and
C = actual charge of coal in tons per oven.
3.5.4.a. The smoke and/or particulate matter emissions discharged from the air pollution control equipment and non-captured pushing emissions shall not exceed 20% opacity.3.5.5. Transport emissions from an enclosed quench car shall not exceed 20% opacity. Transport emissions from an open quench car shall not exceed 10% opacity.3.5.6. Coke side sheds and similar structures used to capture pushing and/or quenching emissions, shall be designed and operated so as to prevent the escape of smoke and/or particulate matter emissions from points other than the stack of the air pollution control equipment.3.5.7. Quench towers shall employ as a minimum, multiple row baffles and use make-up water not to exceed 800 milligrams per liter of total dissolved solids and 100 milligrams per liter of total suspended solids.3.5.8. Smoke and/or particulate matter from the combustion stack shall meet the requirements of subsections 3.1 and 3.2. The particulate matter emissions rate from combustion stacks shall not be greater than 0.060 grains per dry standard cubic foot or 1.0 lb/ton of coal charged, whichever is most restrictive.3.5.9. Good operating practices must be maintained to prevent the atmospheric entrainment of particulate matter resulting from the spillage or other deposition of coal and/or coke.3.6. Basic Oxygen Roof and Blast Furnace Cast House Roof Monitors. -- The provisions of subsections 3.1 or 3.2 shall not apply to smoke and/or particulate matter emitted from the roof monitor(s) of a basic oxygen process or from a blast furnace cast house. The following provisions will apply:3.6.1. Visible emissions from a basic oxygen process roof monitor shall not exceed 20% opacity except for a period or periods aggregating no more than 3 minutes in any 60 minute period where the average opacity for the aggregated period shall not exceed 40% opacity.3.6.2. Visible emissions from a blast furnace cast house shall not exceed 20% opacity except for a period or periods aggregating no more than 5 minutes in any 60 minute period where the average opacity for the aggregated period shall not exceed 40% opacity.3.7. No person shall cause, suffer, allow or permit visible emissions from any storage structure(s) associated with any manufacturing process(es) that pursuant to subsection 5.1 is required to have a full enclosure and be equipped with a particulate matter control device.
