Haulers
Guidance for companies hauling TWW for final disposal
Companies that are contracted to move TWW to disposal facilities, whether from job sites or transfer centers, have mandated responsibilities in transporting the TWW. See the information below and go to the specific topic under the TWW Basics section for detailed guidance.
| Identifying TWW | Determine whether the wood to be removed during projects is treated wood. See guidance |
| Handling | Follow overall recommendations. See guidance |
| Storage | Haulers must follow specific requirements in temporarily storing TWW to prevent unauthorized access and minimize run-off. These may include blocking and tarping, containerizing, storage buildings, containment pads and other methods. TWW may not be accumulated for more than one year from the date of generation. See guidance |
| Labeling | All TWW generated, accumulated, stored or transported by haulers within California must be clearly marked and visible for inspection. See guidance for sample label. |
| Transport | Haulers are considered handlers when transporting TWW and must follow specific requirements for consolidating TWW volumes and provide information that must accompany any shipments for disposal. See guidance |
| Notifications | Haulers are exempt from notification provisions, unless they handle more than 10,000 lbs. of TWW in any calendar year. See guidance |
| Recordkeeping | Haulers are required to keep records of TWW disposal, which may take the form of a log, invoice, manifest, bill of lading, shipping document, or receipt from an approved TWW facility. Such records must be maintained for a minimum of three years. See guidance |
| Reuse | Treated wood removed from its current use can only be reused under specific conditions. See guidance |
| Disposal sites | TWW must be disposed only at authorized disposal sites. Find disposal site |
