7-14 Air

Please clarify whether a control device is proposed for installation on the Emergency Generator, since the estimated Benzene emission rate calculated using the method shown above is an order of magnitude less than the values contained in Table 2.

RESPONSE 7-14

 

The emergency generator will not be equipped with a control device.  The potential benzene emissions from the emergency generator were listed as 4.5 pounds per year in Table 2. The potential emissions of benzene from the emergency generator were estimated as follows:

                 

[7.76 x 10-4 lb/MMBtu] x [19.5 MMBtu/hr] x [300 hours/yr] = 4.5 lb/yr
