Trends in ash disposal (Figure 24) correspond with the company's coal usage during the same period. In 1976, Illinois Power disposed of 746,000 tons of ash; in 1979, disposal increased to 823,800 tons. The level of ash disposal fluctuated over the next twelve years, with an overall decline of 3% between 1976 and 1991, when tons were disposed. Using data submitted by IP to the Federal Energy Regulatory Commission, trends were developed for both fly ash and bottom ash. In 1976, fly ash and bottom ash disposal was 369,500 and 377,000 tons respectively. In 1991, fly ash disposal was 231,000 tons, a 37% decrease. Bottom ash, on the other hand, increased to 512,000 tons, a increase. Central Illinois Light Company Central Illinois Light Company (CILCO), headquar- tered in Peoria, is Illinois' fourth largest electric utility, serving 186,000 customers. Its service territories extend approximately 4,500 square miles through 150 communities in central and east central Illinois. CILCO's three plants in Peoria and Fulton counties have a total name plate rating of milUon kWh. With five major interconnections, the company sends its electricity through circular miles of high voltage transmission lines. Unlike Commonwealth Edison and Illinois Power, CILCO has no nuclear power plants; it relies wholly on fossil fuel for electricity generation. Between 1970 and 1990, its coal usage increased at an annual compound rate of , from million tons a year to million tons per year (Figure 25)..
