UNDERSTANDING EMISSIONS

Fight for Clean Air

Breathing easy

Air pollution has been a long standing issue in communities with bigger populations and industry. Staying healthy and keeping our air clean requires active participation by everyone to report visible emissions and smells that are good indicators of our local air quality.  

REPORT AN ISSUE

TAKING A CLOSER LOOK

POINT SOURCE

POINT SOURCE

POINT SOURCE

Point sources are generally emissions that are released from a discrete source like a stack or "chimney" of a coke oven battery.  They are a high source of particulate and contaminants.  They are often evaluated based on their opacity.

FUGITIVE

POINT SOURCE

POINT SOURCE

The emissions vary where they start and stop compared to a direct point like a stack.  They are normally captured by devices called baghouses and caused by leaks.  They can contain heavy metals, particulate and greenhouse gases.



SECONDARY FORMATION

ATMOSPHERIC POLLUTION

ATMOSPHERIC POLLUTION

Pollution can become worse and be more visible when particulate reacts with other contaminants already present in the air.  More particulate can results in greater amounts of precipitation and the formation of more greenhouse gases.

ATMOSPHERIC POLLUTION

When the weather is not favorable and operations are poor, you will see "bands" and "patches" of pollution that lower air quality.  They result from fugitive, point source and secondary formation.

REPORTABLE EMISSIONS

Coke Ovens (Cokemaking)

Stack Emissions (Cokemaking)

Stack Emissions (Cokemaking)

Coke ovens release many harmful contaminants that are carcinogenic such as benzene.  Emissions can occur from leaking doors, lids, standpipes and collection main. 



Stack Emissions (Cokemaking)

Stack Emissions (Cokemaking)

Stack Emissions (Cokemaking)

Coke Oven Battery (COB) stacks are a common and high source of particulate and contaminants.  Generally, darker emissions indicate higher amounts of contaminants.



Cokemaking operations

Stack Emissions (Cokemaking)

Bleeder Valves (Ironmaking)

 Charging (filling coke ovens with coal) and pushing (removing coke from the ovens) can results in large visible emissions when there are operational difficulties or deficiencies

Bleeder Valves (Ironmaking)

Casthouse Emissions (Ironmaking)

Bleeder Valves (Ironmaking)

The process of making molten iron in a blast furnace can result in a upset where bleeder valves open. When they open, they can release high levels of particulates and gases.

Casthouse Emissions (Ironmaking)

Casthouse Emissions (Ironmaking)

Casthouse Emissions (Ironmaking)

The removal of molten iron (tapping) from a blast furnace can result in the release of high amounts of particulate, often as iron oxides.  They are normally captured by a baghouse.

BOSP Emissions (Steelmaking)

Casthouse Emissions (Ironmaking)

Casthouse Emissions (Ironmaking)

The addition of molten iron and alloys to basic oxygen and ladle metallurgy furnaces to make steel can release numerous contaminants including heavy metals.
