a If you select the regression model option to monitor influent liquid-to-gas ratio as described in Table 3 to this subpart, then you must also continuously monitor (i.e., record every 15 minutes, and use a daily averaging period) blower amperage, blower static pressure (i.e., fan suction pressure), and any other parameters used in the regression model that are not constants.
