Interim Records of Decision Paper

The ASTSWMO Remedial Action Focus Group developed this report to provide information to States and EPA regarding the use of Interim Records of Decision (Interim RODs) at sites subject to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) also known as Superfund.

Sediment Site Recontamination Paper

ASTSWMO’s Sediments Focus Group developed this report to evaluate efforts coordinated across CERCLA and Clean Water Act authorities that were aimed at preventing sediment recontamination. The Focus Group presents several case studies of CERCLA sites that involve a component of sediment remediation through which to explore application of collaborative recommendations jointly developed by several EPA offices.

National Priorities List (NPL) Designation report

ASTSWMO’s Site Assessment Focus Group developed a National Priorities List (NPL) Designation report, which presents results from a research project analyzing States’ views regarding whether additional NPL top-priority designations would be beneficial, and information about unsuccessful site listings.

Site Assessment Program Analysis

ASTSWMO’s Site Assessment Focus Group facilitated the collection of nationally representative data about States’ use of, and recommendations for, the Site Assessment Program tools. Based on information obtained from States regarding the Site Assessment process, the Focus Group developed this report to present key findings.

Transitioning Sites to Post Construction Report

ASTSWMO’s CERCLA Post Construction Focus Group developed this report to provide examples of challenges experienced by various States during the transition of sites from the EPA to a State and present National Priorities List site examples that illustrate opportunities for possible solutions to aid in facilitating more successful transitions.

Superfund State Contracts- A Reference for States and Territories: How to Get the Most Out of Your Superfund State Contract

The ASTSWMO Remedial Action Focus Group developed this report to assist States with the preparation, negotiation, and implementation of their Superfund State Contracts. This document is intended to help States recognize and understand these decision points and provide some implementation strategies to assist with the successful site cleanup. The paper describes statement of work, funding, State assurances, institutional controls, and more.

The Clean Water Act and Sediment Remediation: Using the Data Quality Objectives Process to Help Assure that Remediated Sediment Sites are not Re-Contaminated

The ASTSWMO Sediments Focus Group developed this report for environmental authorities over both the CWA and Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) in a jurisdiction including State, federal, Territorial and/or tribal decision makers. This paper suggests a planning method to help identify possible sources of pollutants that could prevent a site from reaching remedial cleanup levels, remedial action objectives and/or from being recontaminated following the implementation of a successful remedial action.

Post Removals Site Controls: Ensuring the Long-Term Integrity of Removal Actions

The Removals Focus Group developed this report as an update to their 2010 report “Transition Issues Analysis”. One area that needed additional review was Post Removals Site Controls (PRSCs). Timely input from the State is needed throughout the removal decision making process. The document includes Institutional, Proprietary and Government Controls, as well as zoning, groundwater use restrictions, fish consumption advisories, and more.

Analysis of Superfund Site Assessment Program Cooperative Agreements with States: Benefits of Flexibility During Pre CERCLA Screening

In Benefits of Flexibility During Pre CERCLA Screening, this project relies upon feedback from States, EPA OSRTI data and case studies to examine the States’ use of Pre-CERCLA Screening Assessments and how they can be applied most effectively. This report focuses on the PCS process and the beneficial outcomes obtained by States through use of the PCS tool. This report furthers the work of the May 2014 research findings by focusing on States’ use of the PCS process. The goals of this report are to:

  • Obtain additional information about States’ use of PCSs and whether additional flexibility in use of federal funds during the PCS process would be beneficial;
  • Report on number of PCSs performed and their outcomes; and
  • Provide recommendations about the PCS process with supportive, illustrative case studies.

Analysis of Superfund Site Assessment Program Cooperative Agreements with States: Benefits of Effective State and Federal Partnerships

In this Analysis of Site Assessment Program Cooperative Agreements with States report, the Focus Group is following up on the findings of the Superfund Site Assessment Program: Benefits Beyond NLP Listing reports.  The previous reports collected and reported the numbers of non-NPL outcomes on a national scale, however, their scope did not include investigating how these beneficial outcomes occur.  The goals of this report include showing how States leverage CERCLA Site Assessment work products to achieve cleanup outcomes, both NPL and non-NPL.  Additional goals included gathering and analyzing information on how States:

  • Use their Site Assessment Cooperative Agreement funding;
  • Employ efficiencies and best practices to improve the Site Assessment program; and
  • Track non-NPL beneficial outcomes of sites evaluated with their Site Assessment Cooperative Agreement funding.

This Analysis paper reports on the Focus Group’s research methods and shows how States use Site Assessment work products to achieve both NPL and non-NPL cleanup outcomes, multiplying the benefits of the Site Assessment Program. The report also describes: trends in the Site Assessment Program; State’s recommendations for improving the Site Assessment Program; availability of State programs to address NPL-caliber sites; and tracking non-NPL outcomes.
