Reduced Groundwater Remediation: Protective Concen-tration Levels (PCLs) for Class 2 groundwater (GWGWIng) and Class 3 groundwater (GWGWClass3) do not apply within a PMZ. Rather, groundwater must only meet concentration limits (AirGWInhV) protective of vapor exposures on overlying properties and Attenuation Action Levels (AALs) protective of Floral A2 This Presentation will address the basic guidance for working on a TRRP regulated site. TCEQ has published Risk Tables that can be used to define Protective Concentration Levels (PCLs) of a chemical or metal for Constituent of Concern (COC). The tables provide universal (generic) risk PCL levels.

Ecological Risk Assessment Resources Conducting Ecological Risk Assessments at Remediation Sites in Texas (RG-263). 2021 Texas Risk Reduction Program Protective Concentration Level Tables – Excel Version The Critical Protective Concentration Level (PCL), as defined by TRRP, should be used as the risk based clean~up value for those contaminants of concern where this concentration is lower than the risk based concentration developed in the Baseline Human Health Risk Assessment and the ecological risk assessment.

For the purpose o,determining which releases are subject to TRRP,action levels are defned as the lowest applicable Tier I residential protective concentration level (PCL),or a given COC,assuming a 0.5-acre source area and Class 1 groundwater.The table below indicates the appropriate human health exposure pathway action level ,or each

The Texas Risk Reduction Program (TRRP) rule (30 TAC 350) and conforming rule changes were published in the Texas Register on September 17, 1999 and became effective on September 23, 1999. The rule was revised effective March 19, 2007, March 19, 2009, and again Screening Target COCs from PCL Development Overview Objective: To describe a stepwise process to determine if protective concentration levels need to be developed for target chemicals of concern. Audience: The regulated community and environmental professionals.

Introduction This guidance document describes a process to establish human health-based protective concentration levels (PCLs) for total petroleum hydrocarbons (TPH) in accordance with 30 TAC §350.76(g) of the Texas Risk Reduction Program (TRRP) rule. In many instances, the ability to establish PCLs for TPH will be a convenient tool to evaluate the protectiveness of a TCEQ 2016 Update to the Texas Risk Reduction Program (TRRP) – SSCI Environmental We just received the following update from the Texas Commission on Environmental Quality (TCEQ).

TRRP Protective Concentration Levels Provides information on cleanup standards for the Texas Risk Reduction Program (TRRP). The TRRP Tier 1 protective concentration levels (PCLs) are the default cleanup standards in the Texas Risk Reduction Program. Article Subchapter D of the TRRP rule outlines the process by which PCL cleanup levels are calculated. PCLs are risk-based concentration limits for contaminants in the affected environmental media (e.g., soil, groundwater, etc.) that are protective of human health and the environment. The rule describes a three-tiered methodology to calculate the PCLs. The tiers represent increasing Under the TRRP, remedial actions will be required for affected soil and groundwater which contain site contaminants in excess of applicable Protective Concentration Levels (PCLs).

1.1 Applicable Regulatory Requirements Under the Texas Risk Reduction Program (TRRP) rule, all groundwater-bearing units affected by, or reasonably anticipated to be affected by, chemicals of concern (COCs) having concentrations at or above residential groundwater assessment levels must be characterized with regard to the applicable groundwater resource classification, in This document is intended to explain the role of the critical protective concentration level (PCL) in the Texas Risk Reduction Program (TRRP) rule and outline the steps to determine the critical PCL on a site-specific basis. The classification affects which exposure pathways and groundwater protective concentration levels apply for assessing risk and selecting appropriate response actions at sites.

Introduction This document describes the soil and groundwater response objectives that must be achieved in order to attain Remedy Standard A or B. Response objectives are described in §350.31-.33 and .37 and define the performance that soil and groundwater protective concentration level exceedance (PCLE) zones must attain in order for a response action to
