HOT Supervisor examination and license

Effective March 15, 2000, individuals who supervise work at heating oil tank cleanup and voluntary decommissioning projects are required to be licensed by DEQ. This is a new license category and requires that a HOT examination be taken and passed before issuance of the HOT Supervisor License. The new license does NOT authorize the performance of supervisory services for regulated tanks.
The "Oregon HOT Supervisor" examination is given by the International Code Council. The Dec. 18, 2009 ICC UST/AST Examination Information bulletin contains information about the examination, including scheduling instructions, computer based testing services, test locations and sample questions. The fee for the exam is $75, which must be paid by cashier’s check, money order, or government check at the exam center or by credit card at the time you make your reservations or up to three days before the date of the exam. To request a copy of this bulletin, call ICC at 1-888-422-7233 x33823, or visit their web site.
