Ambient Monitoring


Hydrogen sulfide (H2S) monitoring at Pier 2 occurs only during prilled sulfur loading events. The Port uses deployable instrumentation to measure levels of H2S. The instrumentation automatically reports any exceedances or issues to appropriate Port staff via email and text message. Monitoring results are updated daily on this page during loading events.

UPDATE 3/23/2023: Prilled sulfur is loading at Pier 2. The loading will be complete by 3/31/2023. Hydrogen sulfide sensors are deployed and their data will be posted to this page daily. If you have any questions, please reach out to Kevin Anderson ( 360-299-1827).
