Remediation Management of Complex Sites (RMCS-1, 2017), provide a recommended holistic process for management of challenging sites, termed 'adaptive site
management.' By participating in this training course we expect you will learn to apply the ITRC guidance document to: identify and integrate technical and
nontechnical challenges into a holistic approach to remediation; use the Remediation Potential Assessment to identify whether adaptive site management
is warranted due to site complexity; understand and apply adaptive site management principles; develop a long-term performance-based action plan; apply
well-demonstrated techniques for effective stakeholder engagement; access additional resources, tools, and case studies most relevant for complex sites;
and communicate the value of the guidance to regulators, practitioners, community members, and others. For more information and to register, see https://www.itrcweb.org

12, 2020, 1:00PM-3:00PM EST (18:00-20:00 GMT). The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental
Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums.
The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant
and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform
to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals.
The presentation in Philadelphia focused on remedial design, construction, and operation of the in situ thermal treatment and enhanced bioremediation remedies.
The webinar will provide an update on site progress since the end of 2017 and focus on the technical, contractual, and financial challenges associated with
transitioning the project from EPA to the New Mexico Environmental Department after 10 years of RA-O. It will also cover the process of transitioning from ERD
to monitored natural attenuation and long-term vapor intrusion mitigation and lessons learned. Finally, the webinar will present the GIS-based dashboard
that we're using to integrate operation, VOC, geochemical, and microbial data to support continued system optimization (particularly ahead of the transition
of RA-O to the state). For more information and to register, see https://clu-in.org/live. ITRC Characterization and Remediation of Fractured Rock - February 13, 2020, 1:00PM-3:15PM EST (18:00-20:15 GMT). The basis for this training course is
the ITRC guidance: Characterization and Remediation of Fractured Rock. The purpose of this guidance is to dispel the belief that fractured rock sites are too
complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated
porous media, yet there are important differences. By participating in this training class, you should learn to use ITRC's Fractured Rock Document to guide
your decision making so you can: develop quality Conceptual Site Models (CSMs) for fractured rock sites, set realistic remedial objectives, select the best
remedial options, monitor remedial progress and assess results, and value an interdisciplinary site team approach to bring collective expertise to improve
decision making and to have confidence when going beyond containment and monitoring -- to actually remediating fractured rock sites. For more information

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 provide 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.

1:00PM-3:15PM EST (18:00-20:15 GMT). After participating in this ITRC training course, the learner will be able to apply ITRC's Decision Making at Contaminated
Sites: Issues and Options in Human Health Risk (RISK-3, 2015) document when developing or reviewing site-specific risk assessments by: identifying common
issues encountered when alternatives to default parameters and scenarios are proposed during the planning, data evaluation, toxicity, exposure assessment,
and risk characterization and providing possible options for addressing these issues; recognizing the value of proper planning and the role of stakeholders
in the development and review of risk assessments; and providing information (that includes links to additional resources and tools) to support decision
making when alternatives to default approaches, scenarios and parameters are proposed. For more information and to register, see https://www.itrcweb.org

federal cleanup sites being evaluated and addressed under federal programs, including the Comprehensive Environmental Response, Compensation, and Liability
Act (CERCLA or Superfund) and corrective action under the Resource Conservation and Recovery Act (RCRA). The recommendations in this guidance may also be
useful for state, tribal, or other regulatory authorities (e.g., federal facility cleanup programs and approved state RCRA corrective action programs);
though, many states have promulgated state standards that may be considered ARARs under CERCLA. View or download from http://www.epa.gov/pfas/interim-recommen ...
Evaluation of Rotating Cylinder Treatment System? at Elizabeth Mine, Vermont (EPA 600-R-19-194). This report presents a case study of the rotating cylinder
treatment system? (RCTS?) operated at the Elizabeth Mine in Strafford, Vermont. Historical mining at the Elizabeth Mine resulted in mining wastes and mine
drainage contaminating Copperas Brook, Lord Brook, and the West Branch of the Ompompanoosuc River, which led to the mine site being listed on the Superfund
list in 2001. Lime treatment of mining-influenced water is a conventional and effective treatment; however, there are historical issues with high-volume
lime treatment plants being energy-intensive, requiring constant monitoring, having low lime-efficiency rates from less than ideal mixing, and difficulties
in installing at remote locations. The RCTS? is an innovative system designed to address those issues. Following several activities to manage mining wastes
at Elizabeth Mine, an RCTS? system, followed by a sedimentation basin, was constructed to treat high concentrations of iron originating from the base of the
combined tailings pile. Performance was evaluated from eight years of data. Over the eight years, the maximum annual total iron concentration treated was
about 1,700 mg/l and the minimum annual total iron concentration treated was 50 mg/l. The system effectively removed iron to low concentrations, with generally
less than 1 mg/l in the effluent from the sedimentation basin. This report covers operation of the treatment system from May 2009 through November 2017 and data
analysis was completed August 22, 2018. View or download from https://cfpub.epa.gov/si/si_public_recor ...
Alternative Treatment Technologies to Open Burning and Open Detonation of Energetic Hazardous Wastes (EPA 530-R-19-007). The EPA developed and issued
this report in response to inquiries that EPA has received regarding whether there are alternative treatment technologies available to use in place of open
burning and open detonation (OB/OD) of energetic hazardous waste, also commonly referred to as waste explosives. This report communicates the current state
of alternative technologies that may be applicable for energetic hazardous waste including: munitions and explosives; consumer and commercial fireworks;
marine, roadside, and signal flares; auto air bag explosives; and hobby rocket propellants. Specifically, it identifies and describes alternative technologies
that have been developed and their status, the types of waste munitions or energetics a technology can treat, and where deployments have occurred. Thus, it
provides the formative steps for evaluating the efficacy and the pros and cons of the technologies for particular applications. View or download from http://www.epa.gov/hwpermitting/report-a ...
