Description

CertainTeed is an existing facility that produces fiberglass insulation located in Madera County. The site is in an area zoned for heavy industrial uses. Current surrounding land uses are primarily agricultural. The proposed project will not result in any alteration of the present or planned land use. The project entails the modication of one fiberizer line to allow an increase in fiberglass production. The facility has proposed modifications to existing Air District permit units C-261-1 (Batch Material Handling Operation, to increase annual throughput limits from 105,374.6 tpy to 170,820 tpy), C-261-2 (Main Furnace, to increase the daily glass production limit from 325 metric tons/day to 390 metric tons/day and increase the annual glass production from 118,625 metric tons/year to 142,350 metric tons/year), C-261-3 (C-11 Production Line, there is no physical modification proposed for this permit unit; the facility has only proposed to modify the permit conditions that contain the hourly emission rate from the final stack), and C-261-4 (C-12 Production Line, to install two (2) new 4.8 MMBtu/hr fiberizers (for a total of 8 fiberizers for this production line) and to install a new wet cyclonic scrubber serving as a material collector (for a total of 4 wet cyclonic scrubbers)).
