FY 2018 ESTCP Solicitation Released

Posted: January 10, 2017

The Department of Defense's (DoD) Environmental Security Technology Certification Program (ESTCP) released a solicitation on January 5, 2017, requesting proposals for demonstrations of environmental technologies. Researchers from Federal organizations, universities, and private industry can apply for ESTCP funding via the appropriate solicitation. All proposals must respond to a Topic Area associated with the solicitation. Topic Areas for universities, private industry, and Federal organizations outside DoD differ from DoD Topic Areas. ESTCP projects are formal demonstrations in which innovative technologies are rigorously evaluated. ESTCP demonstrations are conducted at DoD facilities and sites to document improved efficiency, reduced liability, improved environmental outcomes, and cost savings. The due date for all pre-proposals is March 9, 2017 by 2:00 p.m. ET.

State Implementation Support Grant

Posted: January 2, 2017

EPA is announcing $1 million in a grant to provide state implementation support related to CERCLA 128(a). The EPA anticipates award of one cooperative agreement to support state implementation for CERCLA 128(a) and other brownfields related issues. The purpose of this cooperative agreement is to fund research, training, and technical assistance to promote and stimulate information exchange among State officials managing solid, hazardous and brownfields response programs (response programs), and EPA officials to jointly resolve Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Section 128(a) "co-implementor and co-regulator" issues, and identify emerging response program issues that are of interest to States. The maximum amount for the cooperative agreement is $1,000,000. The proposal deadline is January 31, 2017.

FY 2017 Brownfields Environmental Workforce Development and Job Training (EWDJT) Grants

Posted: January 2, 2017

These grants are provided to eligible entities, including nonprofit organizations, to develop environmental programs that recruit, train, and place unemployed and under-employed residents of communities affected by brownfields and other environmental contaminants with the skills needed to secure full-time, sustainable employment in the environmental field and in assessment and cleanup work taking place in their communities. Each Environmental Workforce Development and Job Training Grant may be funded up to $200,000 over a three year period. The proposal deadline is February 24, 2017.

EPA Adds Subsurface Intrusion to the Superfund Hazard Ranking System

Posted: December 8, 2016

The U.S. 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.

Voluntary Cleanup Report: Cross Manufacturing,, Inc., Lewis, Kansas

Posted: December 21, 2016

Past operations at the Cross plant included chrome plating. A voluntary cleanup in situ chromium reduction and fixation remedy was completed at the site between 2012 and 2015 to reduce Cr(VI) to the much less toxic and mobile Cr(III). This report describes the completed in situ Cr reduction and fixation remedy, performance monitoring, and site restoration activities. The remedy was completed by delivering the reducing agent calcium polysulfide through direct injection and amendment infiltration galleries, with treatments performed in October 2014 and May 2015.

Direct Push Optical Screening Tool for High-Resolution, Real-Time Mapping of Chlorinated Solvent DNAPL Architecture

Posted: December 21, 2016

This report describes the testing of a new direct-push optical screening tool for high-resolution 3D subsurface mapping of chlorinated solvent DNAPLs in unlithified sediments. The tool was field-tested at a formerly used defense facility in Massachusetts in fall 2013 (Geoprobe® delivery) and again in March 2014 (CPT delivery).The new tool, a laser-induced fluorescence (LIF) technology referred to as "DyeLIF™," was developed and validated during this project and is now commercially available.

Framework Guidance Manual for In Situ Wetland Restoration Demonstration

Posted: December 21, 2016

This manual is a guide to the use of in situ reactive amendment technologies for remediation of contaminated wetland hydric soils, providing a toolbox of methods with which to approach site characterization/monitoring, treatability testing and demonstration, and remedy implementation. This manual (1) provides a repository of literature sources for active in situ remedial projects; (2) outlines a conceptual approach to managing the remediation of wetland hydric soils; (3) offers suggestions for project objectives, metrics, and evaluation criteria; (4) discusses implementation means and methods; and (5) supports an assessment of technology cost. This guide is based upon a field demonstration conducted at Aberdeen Proving Ground to determine the most effective amendment to immobilize PCBs in wetland sediments among the following agents: powdered activated carbon slurry (Slurry Spray), two pelletized AC products (AquaBlok® and SediMite™), and an engineered manufactured soil cover system (sand control).

In-Situ Capping of Contaminated Sediments

Posted: January 19, 2017

This publication was developed to serve as a basis for the design and assessment of remediation alternatives to dredging by providing a technology overview of various capping-based techniques and describing their possibilities and limitations. The guide consists of a main text (Section 30-1E) plus several supporting but stand-alone appendices: a preliminary review of contaminated sediments in Sweden (30-2E); a general overview of established ex situ and in situ sediment remediation technologies (30-3E); a preliminary overview of remedial sediment capping projects worldwide (30-4E); a short discussion on anticipated challenges with capping Sweden's fiberbank sediments (30-5E); an extensive bibliography of international technical references (30-6E); and an overall summary (30-7E).
