Jay Christopher, Senior Scientist at Trihydro, will be presenting on  RSR Maintenance Vents.  Join him and other firms to learn several refineries’ practical approaches to tracking and documenting compliance with the smaller equipment maintenance vents.  These examples will also provide insights to how refining environmental staff have worked with their operations and maintenance personnel to update procedures to ensure compliance with the new maintenance vent provisions.  Real life lessons learned from implementing these procedures during unit recent turnarounds will also be shared.

Join Trihydro’s Chad Flynn for this session! The block session will provide several differing perspectives relating to industry’s continued challenges in dealing with the Refinery Sector Rule’s (RSR) benzene fenceline monitoring requirements. Past environmental conferences have focused largely on the early challenges associated with designing and implementing a fenceline monitoring program relating to EPA’s Methods 325A/B. Mr. Flynn will be on the panel discussing predictive and proactive tools designed to facilitate source identification and resolution of elevated benzene readings.
