Typically drivers are issued a loading rack identification number, or card, by their trucking company. This number provides the authorizing credential that allows drivers to load fuel into a truck. A study earlier this year by the New England Fuel Institute found that many transportation shipping facilities, including a handful of petroleum refineries and terminals not included under the federal Transportation Worker Identity Credential (TWIC), are requiring drivers to present TWIC cards in order to get beyond the facility gate. But unless bulk carriers recover all authorizing credentials when drivers cease employment, or unless the identification code is changed regularly at the terminal, product can be at risk of theft and/or tampering.
Identifying proper separation policies, and then following them each time an employee leaves the company, is something some bulk transporters, especially smaller carriers, may not see as efficient use of time. In the long run however, following strict separation procedures is easier than dealing with lost product, stolen tankers, or unhappy customers.
