For several source categories, emissions either prior to or beginning with 1985 are not available at the more detailed level but are contained in the more aggregate estimate.

One short ton = 2,000 pounds.

" Other" categories may contain emissions that could not be accurately allocated to specific source categories.

Zero values represent less than 500 short tons/ year.

4 of 54 1/ 24/ 05 DCTM_ ARP. xlsCO 1/ 24/ 05 In order to convert emissions to gigagrams ( thousand metric tons), multiply the above values by 0.9072.

Some columns may not sum to totals due to rounding.

For several source categories, emissions either prior to or beginning with 1985 are not available at the more detailed level but are contained in the more aggregate estimate.

One short ton = 2,000 pounds.

" Other" categories may contain emissions that could not be accurately allocated to specific source categories.

Zero values represent less than 500 short tons/ year.

In order to convert emissions to gigagrams ( thousand metric tons), multiply the above values by 0.9072.

Some columns may not sum to totals due to rounding.

For several source categories, emissions either prior to or beginning with 1985 are not available at the more detailed level but are contained in the more aggregate estimate.

One short ton = 2,000 pounds.

" Other" categories may contain emissions that could not be accurately allocated to specific source categories.

Zero values represent less than 500 short tons/ year.

No data was available after 1984 to weigh the emissions from residential wood burning devices.

In order to convert emissions to gigagrams ( thousand metric tons), multiply the above values by 0.9072.

Some columns may not sum to totals due to rounding.

One short ton = 2,000 pounds.

Except for residential wood combustion, combustion source emissions for 1999 2001 include both the condensible and filterable PM fractions;

emissions prior to 1999 include only the filterable PM fraction. Residential wood combustion emissions include both the condensible and filterable PM fractions for all years.

" Other" categories may contain emissions that could not be accurately allocated to specific source categories.

Zero values represent less than 500 short tons/ year.

In order to convert emissions to gigagrams ( thousand metric tons), multiply the above values by 0.9072.

Some columns may not sum to totals due to rounding.

For several source categories, emissions either prior to or beginning with 1985 are not available at the more detailed level but are contained in the more aggregate estimate.

One short ton = 2,000 pounds.

Except for residential wood combustion, combustion source emissions for 1999 2001 include both the condensible and filterable PM fractions;

emissions prior to 1999 include only the filterable PM fraction. Residential wood combustion emissions include both the condensible and filterable PM fractions for all years.

" Other" categories may contain emissions that could not be accurately allocated to specific source categories.

29 of 54 DCTM_ ARP. xlsPM 10 1/ 24/ 05 Zero values represent less than 500 short tons/ year.

In order to convert emissions to gigagrams ( thousand metric tons), multiply the above values by 0.9072.

Some columns may not sum to totals due to rounding.
