[[SIGMA]LdjDdj will be 0 if no VOC solvent is added to the coatings, as received.] where n is the number of different coatings used during the calendar month and m is the number of different diluent VOC-solvents 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 (b)(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 for the performance test providing control device and capture system operating conditions have not changed. The procedure in paragraphs (b)(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.
where He an Hh shall be determined by a method that has been previously approved by the Administrator. The owner or operator may use the values of Se and Sh specified in table 1 or other values determined by a method that has been previously approved by the Administrator.

Two-piece aluminum or steel can: | ||
Exterior base coat operation | 0.75 | 0.25 |
Overvarnish coating operation | 0.75 | 0.25 |
