This page contains the November 2016 ESL List. If you are in need of current ESLs, please go to the Toxicity Factor Database to search for ESLs. The Toxicity Factor Database is a one-stop-shop for information about all toxicity factors developed by the TCEQ Toxicology Division. The last Published ESL lists was November 2016.
The TCEQ oversees the investigation and cleanup of hazardous and nonhazardous pollutants released into the environment. Cleanup is conducted using a risk-based approach outlined in the Texas Risk Reduction Program (TRRP) rule (30 TAC Chapter 350). Major components of the rule include the requirements for assessment, exposure pathways evaluation, development of protective concentration levels (PCLs), property owner and public notice, remedy selection standards, and institutional controls. This page discusses cleanup value differences.
This document summarizes the differences in the way ESLs, inhalation reference values (ReVs), and unit risk factors (URFs) are used in air permitting and air monitoring, as well as introduces “air monitoring comparison values” or AMCVs as a new term.
