Emission factors are not provided for wet grinders because the high-moisture content in these operations can reduce emissions to negligible levels. The emission factors for dryers in Tables 11.24-1 and 11.24-2 include transfer points integral to the drying operation. A separate emission factor is provided for dryers at titanium/zirconium plants
