Section Env-A 3103.03 - Mathematical Equation for Computation of DERs

The amount of DERs shall be calculated in accordance with the following equation:

DERs =₁Sn (AL_A x ER - E_A)

where:

(a) AL = the activity level during the generation period, expressed as a unit of activity, examples of which are:

(1) Gallons of solids applied for stationary sources of VOCs;

(2) Million BTU for stationary sources of NOx;

(3) 1,000 gallons of fuel burned for area sources;

(4) Number of persons affected for area sources; or

(5) Vehicle miles traveled (VMT) for mobile sources;

(b) Subscript A = actual;

(c) ER = the lowest allowable or historical actual emission rate that would have been emitted during the generation period, expressed as a mass per unit of production, examples of which are:

(1) Tons of VOC per gallon of solids applied for stationary sources of VOCs;

(2) Tons of NOx per million BTU for stationary sources of NOx;

(3) Tons of VOC or NOx per 1,000 gallons of fuel burned for area sources;

(4) Tons of VOC or NOx per capita for area sources; or

(5) Tons of VOC or NOx per VMT - for mobile sources;

(d) E = the amount (typically expressed in tons) of emissions; and

(e) n = the number of units comprising the Source.
