What is a Development Support Document?
A Development Support Document (DSD) summarizes how chemical-specific toxicity values were derived based on RG-442, Guidelines to Develop Effects Screening Levels, Reference Values, and Unit Risk Factors.
When are Proposed and Final DSDs Published?
A proposed DSD is published at the TCEQ web site for a 60-day public review and comment period. After public comments are received, the TS will address and resolve all relevant issues and make scientifically defensible changes to the DSD and toxicity values, if needed.
The final DSDs with a Response to Comments, if applicable, are then published on the TCEQ website. Registrants on the Toxicology Announcement List will be notified by e-mail when proposed or final DSDs are posted.
Procedure to Submit Comments
The TD is not accepting comments at this time. Please register to join the Toxicology Announcement List, or stay tuned for more information.
