Where:
MP = Production-based PM mass emission rate, grams of PM per kilogram (pounds of PM per ton) of glass produced.
ER = PM mass emission rate measured using Methods 5 or 17 during each performance test run, grams (pounds) per hour.
P = Average glass production rate for the performance test, kilograms (tons) of glass produced per hour.
Where:
MPM = Production-based metal HAP mass emission rate, grams of metal HAP per kilogram (pounds of metal HAP per ton) of glass produced.
ERM = Sum of the metal HAP mass emission rates for the glass manufacturing metal HAP that are added as raw materials to the glass manufacturing formulation and are measured using Method 29 during each performance test run, grams (pounds) per hour.
P = Average glass production rate for the performance test, kilograms (tons) of glass produced per hour.
