Dock Area PID Data (Historical)
About this Data
When a barge
with dredged material was located at the Confined Disposal Facility (CDF), the air was monitored near the dock using a photoionization detector (PID). This PID monitoring took place daily prior-to and during dredging. Conducting PID monitoring at the dock area provided data on the effects of sediment activity at the barge on emission levels for worker and community safety.
In the past, PID monitoring at the CDF dock face was conducted to monitor VOC emissions from the barges during placement of dredged material into the CDF. From 2012 through 2020, dock face PID monitoring measurements never exceeded site action levels for VOCs for implementation of emission control measures. Dock face PID monitoring will be discontinued during future dredging.
