B. Discrepancy Report
As a waste disposal site operator, you will be checking the Waste Shipment Record (WSR) that accompanies each asbestos waste shipment that arrives at your site to make sure that the information on the WSR accurately describes the waste shipment.
If you see that there is a discrepancy between the number of containers shown on the WSR and the number that you count in the truck you should note this in Item 12 of the WSR and contact the generator to determine if there is a reasonable explanation for the discrepancy.
If you are able to reconcile the apparent discrepancy, make a note of it on the WSR and forward it to the generator as you would normally do.
If you are unable to resolve the discrepancy within 15 days of accepting the waste, you must send a written discrepancy report immediately to the responsible agency in whose jurisdiction the generator of the waste is located.
The discrepancy report should describe the discrepancy in question and the steps you have taken to obtain an explanation for it, such as how and when you attempted to reach the generator.
A copy of the shipment's WSR must accompany the discrepancy report.
