SFTP Standard = SFTP Standard1-[0.35 * (FTP Standard1-Current FTP Standard)]
Where:
SFTP Standard = Applicable full life weighted SFTP standard for NMHC + NOX, PM or CO. The NMHC + NOX and PM standards must be rounded to two decimal places and the CO standard must be rounded to one decimal place.
SFTP Standard1 = Applicable full life Tier 1 SFTP standard for NMHC + NOX or CO from Table S04-5. For PM only, use FTP Standard1 for SFTP Standard1.
FTP Standard1 = Applicable full life Tier 1 FTP standard from Table S04-6 in this paragraph (f). For the Tier 1 NMHC + NOX standard, add the applicable NMHC and NOx standards.
Current FTP Standard = Applicable full life FTP standard from Table S04-1 in paragraph (c) of this section. For the current NMHC + NOX standard, add the NMOG and NOX standards from the applicable bin.
