Should a facility meet one of these criteria, then the facility is required to calculate emissions for Table 2A substances. These screening criteria are not the same as the contaminant reporting thresholds which are listed in Table 2A of the Step by Step Guideline for Emission Calculation, Record Keeping and Reporting. A facility has to report the emissions of the contaminants only if their respective contaminant reporting thresholds for Table 2A substances are exceeded. If a facility meets the screening criteria for Table 2A substances but does not meet or exceed the contaminant reporting thresholds, the facility is not required to report the contami
