- Table 4 to Subpart BBBBBBB of Part 63—Continuous Compliance Demonstration Methods With the Emission Reduction and PM Concentration Requirements

If you are demonstrating compliance with the * * *	You must demonstrate continuous compliance by * * *	1. Requirement to route all process vent streams from equipment in target HAP service to a PM control device with a PM percent reduction efficiency of 95 percent (98 percent for new sources) or an outlet concentration of 0.03 gr/dscf or less	Using one of the following monitoring methods: a. A bag leak detector and alarm system, that notifies operators when a leak in the filter media is detected. b. A control device parameter monitor and alarm system, that notifies operators when the control device is operating outside of the upper or lower thresholds established by the control device manufacturer. Monitored parameters may include electricity supply to vent collection system fans, pressure drop across the control device, or scrubber liquor flow to the control device, as appropriate to the particulate matter control device being used. c. A CPMS, and maintaining records of data verifying that the vent collection system and control device were operated within the range of parameters established to comply with the emission reduction or 0.03 gr/dscf PM concentration requirements (i.e., according to manufacturer's recommendations or at the conditions used during the most recent performance test) while the chemical preparations operation was in target HAP service. The control device monitoring data are averaged over a 24-hour period or an overall average per batch, whichever is less, while the chemical preparations operation is in target HAP service. Monitored parameters may include electricity supply to vent collection system fans, pressure drop across the control device, or scrubber liquor flow to the control device, as appropriate to the particulate matter control device being used.	2. Certification that all process vent streams from equipment in target HAP service will not contain a PM concentration greater than 0.03 gr/dscf	a. Conducting monthly visual inspections of the vent collection system ductwork for leaks.
