Coming Soon! We are excited to announce the upcoming launch of our newly designed HWTS website in August, 2020. The new template design will be easier to navigate and more user-friendly.

Hazardous Waste Tracking System

The Hazardous Waste Tracking System (HWTS) is the Department of Toxic Substances Control’s data repository for hazardous waste Identification (ID) numbers and manifest information. HWTS generates reports on hazardous waste shipments for generators, transporters, and TSDFs. Reports from 1993 to the present are available by clicking on the Reports tab located at the top of this page. You can retrieve information from 10 public reports. These reports are subject to the limitations contained in the official Disclaimer and Data Limitations Statement.
