ITRC Groundwater Statistics for Environmental Project Managers - January 24, 2017, 1:00PM-3:15PM EST (18:00-20:15 GMT). Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training specifically for environmental project managers who review or use statistical calculations for reports, who make recommendations or decisions based on statistics, or who need to demonstrate compliance for groundwater projects. The training class will encourage and support project managers and others who are not statisticians to: use the ITRC Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make better decisions for projects; apply key aspects of the statistical approach to groundwater data; and answer common questions on background, compliance, trend analysis, and monitoring optimization. ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation, and communication of groundwater statistical methods and should lead to greater confidence and transparency in the use of groundwater statistics for site management. For more information and to register, see http://www.itrcweb.org or https://clu-in.org/live.

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - January 26, 2017, 1:00PM-3:15PM EST (18:00-20:15 GMT). Chemical contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI) occurs when these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants. Petroleum vapor intrusion (PVI) is a subset of VI and is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. The ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and this associated Internet-based training provides regulators and practitioners with consensus information based on empirical data and recent research to support PVI decision making under different regulatory frameworks. The PVI assessment strategy described in this guidance document enables confident decision making that protects human health for various types of petroleum sites and multiple PHC compounds. This guidance provides a comprehensive methodology for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live.

Webinar on the CERCLA 108(b) Financial Responsibility Formula - January 30, 2017, 2:00PM-3:00PM EST (19:00-20:00 GMT). EPA plans to host an informational public webinar to describe key aspects of the financial responsibility formula included in the proposed financial responsibility requirements under CERCLA 108(b) for classes of facilities in the hardrock mining industry. EPA has set up an electronic mailbox for participants to submit questions prior to the webinar, and EPA will seek to respond during the webinar. However, due to the volume of questions anticipated, EPA may not be able to respond to all questions. Please submit any advance questions relating to the financial responsibility formula to: 108bwebinarquestions@epa.gov with the subject line "Formula". The deadline for submitting advance questions is January 23, 2017. EPA also expects to accept questions during the webinar. Do not submit comments on the rule to this mailbox. The comment period will begin after publication of the proposed rule in the Federal Register. To ensure EPA considers them, comments on the proposed rule must be submitted in accordance with the instructions provided with the published version of the proposed rule in the Federal Register. For more information and to register, see http://clu-in.org/live.

Revisions to EPA's Preliminary Remediation Goals for Radionuclides (PRG) Electronic Calculator. EPA has finished making revisions to its online risk assessment tool the PRG calculator. The +D and +E isotopes have been removed from the selection list. Now, a user may select the 'Include daughters' checkbox to see PRG output for the entire chain. In the resident, farmer, and indoor worker soil external exposure equations, a new variable has been added (GSFb) to account for the gamma shielding provided by clean soil cover under a building. It is combined with GSFi, the shielding provided by the building, to reduce exposures to receptors inside a building which is on top of clean soil over contaminated soil. Previously, produce intake rates were based on general fruit and vegetable consumption rates. Now, the produce intake rates are derived from 22 individual produce items, found in the 2011 Exposure Factors Handbook, that contribute to the overall produce ingestion PRG. Mass loading factors (MLFs) were also improved, from a single MLF that was applied to all produce, to 22 individual MLFs that correspond with the 22 individual produce items that make up the new produce intake rates. In site-specific mode, users will now able to select additional animal products including Goat Milk, Sheep Milk, Goat Meat, and Sheep Meat, which are not included in the default animal product PRGs. Users will also be able to select Rice and Grains, which are not included in the default produce PRG. Formerly, the transfer factors used in this risk assessment tool were specific to element only. Now, the transfer factors are element, climate zone, soil type, and produce specific. For more detailed information, "Biota Modeling in EPA's Preliminary Remediation Goal and Dose Compliance Concentration Calculators" explains where these new intake rates, MLFs, and transfer factors were sourced and how they will be applied to the PRG calculator. The paper "Biota Modeling in EPA's Preliminary Remediation Goal and Dose Compliance Concentration Calculators" may be found at https://epa-prgs.ornl.gov/radionuclides/20161130_Biota_TM_KLM_Final.pdf. The revised version of the PRG calculator is available at: https://epa-prgs.ornl.gov/radionuclides/.

EPA Adds Subsurface Intrusion to the Superfund Hazard Ranking System. EPA has finalized a proposal to expand the hazards that qualify sites for the Superfund National Priorities List (NPL). EPA assesses sites using the Hazard Ranking System (HRS), which quantifies negative impacts to air, groundwater, surface water and soil. Sites receiving HRS scores above a specific threshold can be proposed for placement on the NPL. Subsurface intrusion is the migration of hazardous substances, pollutants or contaminants from contaminated groundwater or soil into an overlying building. Subsurface intrusion can result in people being exposed to harmful levels of hazardous substances, which can raise the lifetime risk of cancer or chronic disease. This regulatory change does not affect the status of sites currently on or proposed to be added to the NPL. This modification only augments criteria for applying the HRS to sites being evaluated in the future. For more information on the rulemaking, see https://www.epa.gov/superfund/hrs-subsurface-intrusion.
