Foot Notes

[1] Aluminum Foundries (casting) (Nov. 2002 Inventory) 

combines two May 1999 categories: Aluminum Foundries and 

Aluminum Foundries (casting)

[2] Cyclic Crude and Intermediate Production was titled Cyclic 

Crude and Intermediate Production (not subject to petroleum 

refining MACT) in the May 1999 Report

[3] Hazardous Waste Incinerators were only included in the 

May 1999 Report for dioxins/furans; additionally, those 

emissions were all attributed to major sources

[4] Portland Cement was only included in the 1999 inventory 

for dioxins/furans

[5] Pressed and Blown Glass and Glassware Manufacturing 

(Nov. 2002 Inventory) combines two May 1999 categories: 

Pressed and Blown Glass and Glassware Manufacturing and 

Glass Containers

[6] Primary Nonferrous Metals - Zn, Cd & Be (Nov. 2002 

Inventory) combines three May 1999 categories: Cadmium 

Refining and Cadmium Oxide Production, Primary Smelting 

and Refining of Zinc, and Primary Nonferrous Metals
