Yes the TWIC is a big deal. i work for a company located on the Ohio river that loads/unloads chemical barges as part of our plastic manufacturing. They are saying that everyone on site will have to have a TWIC card or that we will have to add even more security fence inside the perimeter of the plant to further secure areas from the workers without TWIC approvals This will include all personnel and contractors. Our plant is right at 1300+ workers and a few hundred contractors daily and as many as a 1000 contractors during our maintenance shutdowns.
