The fume suppressant annual costs documented in an MRI memorandum to 

EPA dated August 4, 1988, have been updated from October 1986 dollars to 

November 1988 dollars. Costs were updated using the Chemical Engineering 

(CE) plant index, from the February 1989 issue of Chemical Engineering. 

The most recent final CE plant index was for November 1988. Therefore, 

November 1988 was chosen as the basis for the updated costs. The ratio of 

the CE Plant Indices for November 1988 (347.8) and October 1986 (319.3), 

equal to 1.09, was used to update costs. 

The revised annual costs of permanent and temporary fume suppressants 

for the decorative chromium electroplating model plants, in November 1988 

dollars, are shown in Tables 1 and 2. The average annual cost of 

permanent fume suppressants for the chromic acid anodizing model plants, 

in November 1988 dollars, is presented in Table 3.
