Passive Air Monitoring System (PAMS) Data
The Shell Polymers Monaca (SPM) site conducts bi-weekly passive sampling for Chemicals of Potential Concern, which include Benzene, Hexane, 1-3 Butadiene, toluene, and Naphthalene. To conduct this monitoring, Shell has installed twenty (20) Passive Air Monitoring System (PAMS) locations.
The PAMS samples are collected and analyzed in accordance with 40 CFR 63.658(e)(1)-(2).These regulations prescribe methods for passive absorption sampling in which clean absorbent tubes are deployed and collected every two weeks and sent to a third-party analytical laboratory for analysis.Upon collection of the used sampling tubes, a new set of tubes are deployed to begin sample collection for the next two-week period. Benzene concentration delta [or (Δc)] is reported from the 2-week sample period and is calculated using the minimum and the maximum individual monitoring point sample results.If the 2-week Δc is greater than the applicable Action Threshold, then an investigation is initiated within 24-hours.
