Risk Assessments at Remediation Sites in Texas and Bills of Interest in the Texas State Legislature Introduced

The 2017 version of Conducting Ecological Risk Assessments at Remediation Sites in Texas (ERAG, RG-263) is now available through TCEQ’s ERA Home Page at: www.tceq.texas.gov/goto/era . Links for the new Supporting Documentation for the TCEQ’s Ecological Benchmark Tables and the accompanying Excel file that houses the numeric screening-level benchmarks – the combination of which comprises RG-263B – are also available through the home page. A case study that will include examples of a Tier 1 Exclusion Criteria Checklist, a Tier 2 Screening Level Ecological Risk Assessment, and an Ecological Services Analysis will be RG-263C when it becomes available. TCEQ and its contractor – West Texas A&M University (WTAMU) – have developed an Ecological Protective Concentration Level (PCL) Database that provides default PCLs for soil and sediment for a variety of wildlife receptors and contaminants. A WTAMU link to the database appears on the home page, making it available for public use and citation, as appropriate.
