What is a PCW Transporter? A PCW Transporter is a person who transports PCW off-site by rail or over public roads. A Transporter who is not a producer or who does not engage in the ultimate recovery of product from PCW must not store PCW on-site for more than 35 days. [Rule 62-740.200, FAC]

Notification Requirements A Transporter of PCW destined for recovery must be a hazardous waste Transporter in compliance with Chapter 62-730, FAC, or receive an EPA ID number by notifying the Department on form 62-730.900(a)(b) of its intent to transport PCW. [Rule 62-740.200, FAC]

Storage Container Requirements A Transporter that stores PCW in containers and tanks not required to be registered in accordance with Chapters 62-761 or 62-762, FAC, must comply with the following: Ensure that the container or tank is made of or lined with material that is compatible with PCW; Keep the container or tank closed and stored in a safe manner; Label or mark the container or tank clearly with the words Petroleum Contact Water and the date when PCW accumulation first begins after the existing PCW in the container or tank has been removed; Not handle the container or tank in a manner that may rupture it or cause it to leak; and Inspect the container or tank for leaks and deterioration at least weekly [Rule 62-740.200, FAC].
