where
n is the number of different coatings used during the calendar month, and
m is the number of different VOC solvents added to coatings used during the calendar month.
Where:
n is the number of different coatings used during the calendar month.
For the initial performance test, the overall reduction efficiency (R) shall be determined as prescribed in paragraphs (c)(2)(i) (A), (B), and (C) of this section. In subsequent months, the owner or operator may use the most recently determined overall reduction efficiency (R) for the performance test, providing control device and capture system operating conditions have not changed. The procedure in paragraphs (c)(2)(i) (A), (B), and (C) of this section, shall be repeated when directed by the Administrator or when the owner or operator elects to operate the control device or capture system at conditions different from the initial performance test.
Equation 5
Where:
l is the number of gas streams entering the control device, and
p is the number of gas streams emitted directly to the atmosphere.
Equation 6
Where:
n is the number of gas streams entering the control device, and
m is the number of gas streams leaving the control device and entering the atmosphere.
The owner or operator of the affected facility shall construct the VOC emission reduction system so that all volumetric flow rates and total VOC emissions can be accurately determined by the applicable test methods and procedures specified in § 60.466 . The owner or operator of the affected facility shall construct a temporary enclosure around the coating applicator and flashoff area during the performance test for the purpose of evaluating the capture efficiency of the system. The enclosure must be maintained at a negative pressure to ensure that all VOC emissions are measurable. If a permanent enclosure exists in the affected facility prior to the performance test and the Administrator is satisfied that the enclosure is adequately containing VOC emissions, no additional enclosure is required for the performance test.
If the overall reduction efficiency (R) is equal to or greater than 0.90, the affected facility is in compliance and no further computations are necessary. If the overall reduction efficiency (R) is less than 0.90, the average total VOC emissions to the atmosphere per unit volume of coating solids applied (N) shall be computed as follows.
If the overall reduction efficiency (R) is equal to or greater than 0.90, the affected facility is in compliance and no further computations are necessary. If the overall reduction efficiency (R) is less than 0.90, the average total VOC emissions to the atmosphere per unit volume of coating solids applied (N) must be computed as follows.
Where:
n is the number of coatings used during the calendar month without the control device in operation.
Where:
n is the number of coatings used during the calendar month with the control device in operation.
Where:
n is the number of different coatings used without the control device in operation during the calendar month, and
m is the number of different VOC-solvents added to coatings used without the control device in operation during the calendar month.
Where:
n is the number of different coatings used with the control device in operation during the calendar month, and
m is the number of different VOC-solvents added to coatings used with the control device in operation during the calendar month.
