combination boilers was 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

promulgations of federal regulations as of October 3, 2008, for New
