CEC Preliminary Assessment/Site Inspection (PA/SI) Webinar Series, Module 1: Overview of the Site Assessment Process under CERCLA

The CERCLA Education Center (CEC) is offering a nine-part Preliminary Assessment and Site Inspection (PA/SI) Webinar Series in June and July 2014. PA/SI is an intermediate training course designed for personnel who are required to compile, draft and review PA, SI and HRS documentation records and packages submitted for sites proposed for the National Priorities List (NPL). This course is open to EPA, federal, state, tribal and contractor personnel who support site investigation programs.

The PAS/SI Webinar Series provides an introduction to the Superfund site assessment process and describes the preliminary assessment and site inspection phases of this process. The course will incorporate a mix of lecture and exercises using Quickscore for each of the four pathways. The objective of the exercise is to give participants the opportunity to evaluate and score PA information using the HRS Quickscore software. Participants will use information from a fictitious site to (1) evaluate and calculate a preliminary HRS score, and (2) develop release and target hypotheses that should be pursued in an SI.

In order to receive credit for taking the course, participants must participate in each session. If you are unable to make one of the sessions, archived versions will be made available at www.clu-in.org that you can take to receive credit for the missed live session.

Soil Amendment Applications and Mine Site Restoration Impacts on Soil Ecosystem Services

The next webinar in our CLU-IN mining webinar series will address topics in soil remediation and restoration. Presenters will discuss their research on the use of soil amendments, the impact of soil restoration at mine sites on ecosystem function and services, and deliberate decision-making in site restoration that benefits the whole ecosystem.

Dr. Sally Brown will discuss how using residuals led to the development of new soil at a Jasper County, MO Superfund site. Her research team amended mine tailings at the site in the late 1990s and completed sampling in 2012. Dr. Brown will discuss the successful use of residuals at the site, as well as the ecological and economic values of using residuals even when replacement topsoil is readily available. The significance of considering the final fate of the site using a life cycle assessment will also be discussed.

Andrew Trlica will present his research that measured soil carbon storage in former surface mines under long-term reclamation. He compared areas reclaimed with biosolids-based soil amendments with areas reclaimed using conventional approaches. This study went on to use a life cycle assessment approach to examine the relative greenhouse gas balance and other ecosystem effects of different land reclamation strategies (for example, restoring a site to a low density residential use in comparison with restoring to a forest).

Superfund and Renewable Energy: Promising Futures for Sites with a Contaminated Past

EPA has placed national priority on showcasing opportunities for the development of clean and renewable energy projects on contaminated lands. EPA's Superfund Redevelopment Initiative (SRI) supports the use of renewable energy at Superfund sites and has actively provided site owners and local communities with technical support and resources to explore innovative reuse opportunities available at these sites. Highlighting SRI's support activities as well as case studies from sites with solar projects in place and generating electricity, this webinar will highlight how EPA worked with site stakeholders and solar developers to design and enable renewable energy project fully compatible with long-term protectiveness of a site. It will also focus on the challenges and benefits found in developing a large solar facility on formerly contaminated sites (e.g., landfills) and highlight the role of these sites in supporting development and how local communities and site owners can see economic and environmental impacts from renewable energy development on current and formerly contaminated lands.

Soil Sampling and Decision Making Using Incremental Sampling Methodology - Part 1

Interstate Technology Regulatory Council When sampling soil at potentially contaminated sites, the goal is collecting representative samples which will lead to quality decisions. Unfortunately traditional soil sampling methods don't always provide the accurate, reproducible, and defensible data needed. Incremental Sampling Methodology (ISM) can help with this soil sampling challenge. ISM is a structured composite sampling and processing protocol that reduces data variability and provides a reasonable estimate of a chemical's mean concentration for the volume of soil being sampled. The three key components of ISM are systematic planning, field sample collection, and laboratory processing and analysis. The adequacy of ISM sample support (sample mass) reduces sampling and laboratory errors, and the ISM strategy improves the reliability and defensibility of sampling data by reducing data variability.

ISM provides representative samples of specific soil volumes defined as Decision Units. An ISM replicate sample is established by collecting numerous increments of soil (typically 30 to 100 increments) that are combined, processed, and subsampled according to specific protocols. ISM is increasingly being used for sampling soils at hazardous waste sites and on suspected contaminated lands. Proponents have found that the coverage afforded by collecting many increments, together with disciplined processing and subsampling of the combined increments, yields consistent and reproducible results that in most instances have been preferable to the results obtained by more traditional (e.g. discrete) sampling approaches.

This 2-part training course along with ITRC's web-based Incremental Sampling Methodology Technical and Regulatory Guidance Document (ISM-1, 2012) is intended to assist regulators and practitioners with the understanding the fundamental concepts of soil/contaminant heterogeneity, representative sampling, sampling/laboratory error and how ISM addresses these concepts. Through this training course you should learn:

  • basic principles to improve soil sampling results
  • systematic planning steps important to ISM
  • how to determine ISM Decision Units (DU)
  • the answers to common questions about ISM sampling design and data analysis
  • methods to collect and analyze ISM soil samples
  • the impact of laboratory processing on soil samples
  • how to evaluate ISM data and make decisions

In addition this ISM training and guidance provides insight on when and how to apply ISM at a contaminated site, and will aid in developing or reviewing project documents incorporating ISM (e.g., work plans, sampling plans, reports). You will also be provided with links to additional resources related to ISM.

The intended users of this guidance and training course are state and federal regulators, project managers, and consultant personnel responsible for and/or directly involved in developing, identifying or applying soil and sediment sampling approaches and establishing sampling objectives and methods. In addition, data end users and decision makers will gain insight to the use and impacts of ISM for soil sampling for potentially contaminated sites.

Recommended Reading: We encourage participants to review the ITRC ISM document(http://www.itrcweb.org/ISM-1/) prior to participating in the training classes. If your time is limited in reviewing the document in advance, we suggest you prioritize your time by reading the Executive Summary, Chapter 4 "Statistical Sampling Designs for ISM," and Chapter 7 "Making Decisions Using ISM Data" to maximize your learning experience during the upcoming training classes.

Mining Waste Treatment Technology Selection

Interstate Technology Regulatory Council Mining produces millions of tons of waste each year. Contaminants from unreclaimed or unremediated areas have affected millions of acres of land and over 10,000 miles of stream. Historical mining practices and the absence of routine mined-land reclamation, remediation, and restoration have led to legacy sites with significant environmental and human health impacts. New mining operations continue to have severe waste issues that must be addressed during and after the actual mining operation. Conventional remedial solutions are often lengthy, expensive, and unacceptable to the regulated and regulatory communities, as well as to the public.

ITRC's Mining Waste Team developed the ITRC Web-based Mining Waste Technology Selection site to assist project managers in selecting an applicable technology, or suite of technologies, which can be used to remediate mine waste contaminated sites. Decision trees, through a series of questions, guide users to a set of treatment technologies that may be applicable to that particular site situation. Each technology is described, along with a summary of the applicability, advantages, limitations, performance, stakeholder and regulatory considerations, and lessons learned. Each technology overview links to case studies where the technology has been implemented. In this associated Internet-based training, instructors provide background information then take participants through the decision tree using example sites. Project managers, regulators, site owners, and community stakeholders should attend this training class to learn how to use the ITRC Web-based Mining Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints.

Biochemical Reactors for Treating Mining Influenced Water

Interstate Technology Regulatory Council Mining influenced water (MIW) includes aqueous wastes generated by ore extraction and processing, as well as mine drainage and tailings runoff. MIW handling, storage, and disposal is a major environmental problem in mining districts throughout the U.S and around the world. Biochemical reactors (BCRs) are engineered treatment systems that use an organic substrate to drive microbial and chemical reactions to reduce concentrations of metals, acidity, and sulfate in MIWs. The ITRC Biochemical Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013) and this associated Internet-based training provide an in-depth examination of BCRs; a decision framework to assess the applicability of BCRs; details on testing, designing, constructing and monitoring BCRs; and real world BCR case studies with diverse site conditions and chemical mixtures. At the end of this training, you should be able to complete the following activities:
  • Describe a BCR and how it works
  • Identify when a BCR is applicable to a site
  • Use the ITRC guidance for decision making by applying the decision framework
  • Improve site decision making through understanding of BCR advantages, limitations, reasonable expectations, regulatory and other challenges
  • Navigate the ITRC Biochemical Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013)

For reference during the training class, participants should have a copy of Figure 2-1, decision flow process for determining the applicability of a biochemical reactor. It is also available as a 1-page PDF at http://www.cluin.org/conf/itrc/BCR/ITRC-BCRforMIW-DecisionFlow.pdf.

Participants should also be familiar with the ITRC technology and regulatory guidance for Mining-Waste Treatment Technology Selection (MW-1, 2010) and associated Internet-based training that helps regulators, consultants, industry, and stakeholders in selecting an applicable technology, or suite of technologies, which can be used to remediate mining sites.
