amended by adding language to clarify applicability to devices produce steam or heat water 

or other heat transfer medium through indirect means.

Paragraph 3.6(a) relating to particulate matter emission limits based on process weight rate 

was amended to clarify that the emission limit applies to the manufacturing process including 

any associated stacks, vents, outlets, or combination thereof.

Paragraph 3.7 “Open Burning” regarding permits from the Mississippi Forestry Commission 

was updated in accordance with current requirements.

Paragraph 3.8 “Incineration” was amended by adding subparagraph c to clarify applicability.

Clean Air Mercury Rule (CAMR) provisions in Section 8. Paragraph 4. were updated as of 

October 3, 2008, in accordance with recent federal promulgations.
