MEMORANDUM 

SUBJECT: Addition of F-factors for Municipal Wastes to Method 19 

FROM: Lori T. Lay, Test Support Section t-Ti-

Emission Measurement Branch, ESED (MD-19) 

TO: Walt Stevenson, Regulations Development Section 

Standards Development Branch, ESED (MD-13) 

In reference to my memorandum of July 23, 1987, regarding the revision 

of Method 19, I have researched the possibility of adding additional 

F-factors for municipal wastes. 

Data were analyzed from the following tests: (1) Municipal 

Incinerators Tests at Chicago Solid Waste Disposal System in May 1973; 

(2) St. Louis Union Electric in August 1974; and (3) Dade County, Florida 

in October 1975. 

The Fc and Fj factors were calculated from fuel analysis data according 

to the equations in Method 19. The F« factors were also calculated for 

comparison. The values are shown in Table 1. The recommended F-factors are 

the midpoint values of the test averages which are shown in Table 2. 

The midpoint Fc factor is 1820 dscf/106 Btu (0.4880 x 10~7 dscm/J) 

with a range of +6 percent to -5 percent. The midpoint F^ factor for the 

wastes is 9570 dscf/106 Btu (2.570 x 10~7 dscm/J) with a range of +4 percent 

to -3 percent. The midpoint F0 value is 1.100 with a range of +5 percent 

to -7 percent. The range for the values was based on all individual 

data points. The values have been rounded off to be consistent with 

Method 19. 

The Florida data are not included in the table because no information 

was available to determine the Fc and F<j values for the wastes. In 

addition, there was an analytical equipment deficiency. However, the 

average F0 value (1.10) for the Florida tests fell within the range of the 

other two tests which indicated that the nature of the municipal waste was 

similiar to the other two. 
P.3 

The Fc and F^ factors listed in Table 1 are consistent for both the 

Chicago and the St. Louis tests, and it appears that the F-factors will not 

be appreciably different in other parts of the country; therefore, the 

midpoint values shown above may be listed in Table 19-1 of Method 19 to be 

used in the calculation of emission rates from municipal incinerators.
