What is the Consolidating Manifesting Procedure?

Consolidating manifesting (formerly known as modified manifesting or “milk runs”) is when a transporter’s and generator’s hazardous waste meets the conditions in Health and Safety Code 25160.2, to consolidate shipments of waste streams identified in subdivision (c) collected from multiple generators onto a single consolidated manifest, which is the Uniform Hazardous Waste Manifest (U.S. EPA Form 8700-22).

How to report consolidated waste in Step 8 of the eVQ, as a Generator or Transporter. 

Generator

Generators participating in consolidated manifesting activities must report their consolidated waste. A generator can find the generator ID number on a receipt, bill of lading, or a weight ticket that was provided by the transporter. 

Transporter

Transporters participating in consolidated manifesting activities must report their consolidated waste. The transporter must enter the ID number(s) used on a single manifest, that was used during the consolidated waste pick-ups. Transporters are required to report this information in DTSC’s Transporter Quarterly Report (TQR) system.

Waste Streams Under the Consolidated Manifesting Procedure

• Used Oil
• Contents of an oil/water separator
• Solids contaminated with used oil
• Brake fluid
• Antifreeze
• Antifreeze sludge
• Parts cleaning solvents, including aqueous cleaning solvents
• Hydroxide sludge contaminated solely with metals from a wastewater treatment process
• Paint-related wastes, including paint, thinners, filters, and sludges
• Spent photographic solutions
• Dry cleaning solvents (including perchloroethylene, naphtha, and silicone-based solvents
• Filters, lint, and sludges contaminated with dry cleaning solvent
