What the source says
This regulation applies to sources of air toxics in two separate source categories: asphalt processing facilities and asphalt roofing manufacturing facilities. Asphalt processing facilities produce “blown” asphalt for use in the asphalt roofing manufacturing industry and elsewhere. Asphalt roofing manufacturing facilities produce shingles and roll roofing products by applying the “blown” asphalt to a fiberglass or felt substrate. Both types of facilities can be located together but asphalt processing facilities can also be located at refineries.
