Fugitive and Equipment Emissions Determination (Non -point Source):
Fugitive / Equipment Emissions
Page 1 of 2
Fugitive (FE) and Equipment Emissions (EE) are a function of the number of emission points in the
plant (valves, flanges, pump seals). The inventory shown below is conservative and based on plant
and process diagrams. Note that the calculations below include the following: (1) equipment emissions
emissiions not inside buildings, which are "fugitive" in nature and will be reported as such, and
(2) equipment emissiion in side buildings, which are not "fugitive" in nature and will be reported as
equipment emissions only.
A. Fugitive emissions from MMF equipment outside of the barricade:
Emissions from this equipment are not inside a building and are therefore "fugitive" in nature.
Valve emissions: 552 valves x 0.00036 Ib/hr/valve = 0.199 Ib/hr EE
Flange emissions: 100 flanges x 0.00018 Ib/hr/flange = 0.018 Ib/hr EE
Total equipment emission rate = 0.217 Ib r E
Days of operation = 107
On average 0.13 Ibs of HF are produced for every 1 pound of process material released
VOC: 0.217 Ib/hr EE
x 24 hours/day
x 107 days/year
= 556.5 Ib/yr VOC from EE
HF: 0.217 Ib/hr EE
x 24 hours/day
x 107 days/year
x 0.13 lb HF per lb VOC
72.3 Ib/yr HF from EE
B. Equipment Emissions From MMF Reactor and Transfer Tank
This equipment is inside a building, therefore emissions are not true Fugitive Emissions
Valve emissions: 88 valves x 0.00036 Ib/hr/valve = 0.032 Ib/hr FE
Flange emissions: 10 flanges x 0.00018 Ib/hr/flange = 0.002 Ib/hr FE _
Total fugitive emission rate = 0.033 Ib/hr FE
VOC: 0.033 lb. FE/hr HF: 0.033 lb. FE/hr
x 24 hours/day x 24 hours/day
x 107 days/year x 107 days/year
86.0 Ib/yr VOC from EE x 0.13 lb HF per lb VOC
11.2 Ib/yr HF from EE

Note: Speciated equipment emissions were estimated by assuming that each
compound's equipment emission concentration was equal to that compound's
stack emission fraction of the total stack emission.
Example: The DMC equipment emissions were determined by the ratio of the
DMC stack emission (254.7 lb) divided by the total stack emission (306.7 lb),
multiplied by the total equipment emissions (358.9 lb).
Specifically: 500.1 556.5 = 462.2 lb. DMC
