Foot Notes

[1] Hazardous Waste Incinerators were only included in the 

May 1999 Report for dioxins/furans; additionally, those 

emissions were all attributed to major sources

[2] May 1999 Report categories Animal Cremation and Human 

Cremation were grouped into Other Solid Waste Incineration 

(Nov. 2002 Inventory) and broken out again into Animal 

Cremation and Human Cremation for mercury in this inventory

 [3] Mercury Cell Chlor-Alkali Plants (Nov. 2002 Inventory) 

combines two May 1999 categories: Mercury Cell Chlor-Alkali 

Plants and Chlorine Production

[4] Plastics Materials and Resins Manufacturing (Nov. 2002 

Inventory) was titled Polymers and Resins (I,II,IV) in the May 

1999 Report

[5] Mercury emissions from Portland Cement area source 

based on 20% of 112(c)(6) inventory

[6] Stainless and Nonstainless EAF (Nov. 2002 Inventory) 

combines two May 1999 categories: Stainless and 

Nonstainless EAF and Blast Furnaces and Steel Mills' area 

sources 

[7] Three source categories had mercury emissions in the May 

1999 Report, but were removed in the Nov. 2002 Inventory: 

Chemical Manufacturing: Alkalies and Chloride (not subject to 

Chlorine Production MACT), Primary Copper Smelting, and 

Stationary Internal Combustion Engines; alsoAnimal Cremation 

was determioned not to be a source of mercury emissions after 

the Nov. 2002 Inventory

[8] Primary Copper Smelting was removed from the 2002 

Inventory
