> Request for Proposals
2014 ITRC Projects in the Remediation Area. The Interstate Technology &
Regulatory Council (ITRC) requests proposals for 2014 ITRC projects in the
remediation area only. ITRC would like to focus proposals on the following topical
areas: site characterization, sampling, and monitoring; soil and groundwater
contamination, specifically groundwater or contaminant fate and transport modeling;
and long term stewardship, land use controls, and institutional controls. Proposals on
other topics will be considered, but preference will be given to those that address one
of the areas above. Proposals are due by 5:00 pm Eastern time on Friday, June 14,
2013. For more information and instructions, see

> Upcoming Live Internet Seminars
NARPM Presents...RECs, Renewables and Remediation - June 6, 2013,
1:00PM-3:00PM EDT (17:00-19:00 GMT). This introductory level session provides an
overview of the spectrum of options available to reduce, or at least offset, the energy
footprint of your sites. We explain what renewable energy credits (REC) really are,
provide information about generating small-scale renewable energy on-site using
mobile systems and cover the basics of how to evaluate the feasibility of using on-site
renewable energy to power a remedy. The session includes a presentation on a
Screening-Level Renewable Energy Assessment that was conducted for a site in the
EPA Region 3, which systematically evaluated the existing energy infrastructure
available for the site and options for onsite electricity generation via wind, solar,
biomass, geothermal and hydropower. Our goal is that participants leave the session
with sufficient information to feel comfortable evaluating and selecting greener energy
strategies for their sites. This course should be suitable for all RPMs. For more
information and to register, see httn://ciu-in.nm/iive .

ITRC Development of Performance Specifications for Solidification/Stabilization -
June 25, 2013, 2:00PM-4:15PM EDT (18:00-20:15 GMT). The ITRC technical and
regulatory guidance document Development of Performance Specifications for
Solidification/Stabilization (S/S-1, 2011) and associated Internet-based training provide
an approach to assist practitioners and regulators with measuring and determining
acceptable S/S performance. This approach developed by the ITRC
Solidification/Stabilization Team provides information for developing, testing, and
evaluating appropriate site-specific performance specifications and the considerations
for designing appropriate long-term stewardship programs. In addition, the approach
provides useful tools for establishing an appropriate degree of treatment and regulatory
confidence in the performance data to support decision-making. This training and
guidance is intended to be beneficial to anyone involved with CERCLA, RCRA,
Brownfields, UST or any other regulatory program where S/S has been selected or
implemented as a remedial technology. For more information and to register, see
http://www.itrcweb.ora OP http://clu-in.ora/live .
ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation -
June 27, 2013, 11:00AM-1:15PM EDT (15:00-17:15 GMT). This training, which is
based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and
Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and
conventional fuels specific to release scenarios, environmental impacts,
characterization, and remediation. The trainers will define the scope of the potential
environmental challenges by introducing biofuel fundamentals, regulatory status, and
future usage projections. Participants will learn how and when to use the ITRC biofuels
guidance document for their projects. They will understand the differences in biofuel
and petroleum behavior; become familiar with the biofuel supply chain, potential
release scenarios and release prevention; be able to develop an appropriate
conceptual model for the investigation and remediation of biofuels; and select
appropriate investigation and remediation strategies. For more information and to
register, see http://www.itrcweb.ora Or http://clu-in.ora/live .
How Enforcement Actions can Support Reuse at Superfund Sites - June 27, 2013,
2:00PM-4:00PM EDT (18:00-20:00 GMT). EPA's enforcement program strives to
balance our primary mission of ensuring that polluters pay for cleanups through an
enforcement first strategy with strong support for EPA's contaminated site reuse
goals. As such, the enforcement program helps facilitate site cleanup by pursuing
responsible parties, but also recognizes that supporting reuse efforts can be a powerful
incentive to encourage expeditious cleanups, save limited federal and state cleanup
resources and help us all achieved our cleanup and enforcement goals to protect
human health and the environment. This webinar will discuss the role of EPA's cleanup
enforcement program in supporting the appropriate reuse of Superfund sites and will
share case study examples of how enforcement tools, such as institutional controls,
bona fide prospective purchaser (BFPP) criteria and continuing obligations, and
negotiations to help address liability concerns, can help facilitate beneficial reuse at
Superfund sites. For more information and to register, see http://ciu-in.ora/iive .

Water Contamination Site Second Street Subsite is located in Hastings, Adams County,
Nebraska. The Second Street Subsite has been divided into two OUs: (1) OU 12
addresses the contaminated soils and source materials at the subsite, and (2) OU 20
addresses the contaminated groundwater that extends from the source area and has
migrated beyond the Second Street Subsite boundaries. The Second Street Subsite is
a former manufactured gas plant (FMGP); benzene, toluene, ethyl benzene, xylenes
(collectively referred to as BTEX) and other VOCs (for example, styrene) and
polynuclear aromatic hydrocarbons (PAHs) have been detected in the Second Street
Subsite soil and groundwater, indicating that wastes remaining from the FMGP have
contaminated the soil and groundwater (May 2013, 70 pages). View or download at

Technology News and Trends (EPA 542-N-13-002). This issue highlights vapor
intrusion (VI), which generally refers to migration of hazardous vapors from any
subsurface contaminant source such as contaminated soil or groundwater through the
vadose zone and into indoor air. Vapor intrusion can occur in a broad range of land use
settings, including residential, commercial, and industrial properties, and can affect
buildings with virtually any type of foundation such as basement, crawl space, or slab
on grade. The VI pathway has become a standard consideration during investigations
at hazardous waste sites, especially those subject to the Superfund, underground
storage tank (UST), and Resource Conservation and Recovery Act programs operated
by federal or state agencies. The U.S. EPA currently is finalizing its guidance on
subsurface VI. In addition, 24 states issued draft or final VI guidance as of April 2013,
and other state guidance continues to evolve (May 2013). View at http://ciu-in.ora/tnandt/0513 .
Use of Amendments for In Situ Remediation at Superfund Sediment Sites
(OSWER Directive 9200.2-128FS). This document introduces the most promising
amendments for in situ remediation of sediments and summarizes some of the
information on contaminated sediment sites that have already employed these
amendments. This document is not a guidance or design document and provides
information on the state of the practice of the use of amendments for in situ remediation
of contaminated sediments, as well as three case studies where these amendments
have been used. This document also focuses on the use of amendments either by
themselves or in conjunction with a conventional isolation cap or a thin layer cap and
enhanced Monitored Natural Recovery (EMNR). The amendments discussed are
designed to treat hydrophobic organic contaminants, metals, or both. Some of these
amendments may also be effective in reducing risks from NAPL (April 2013, 61 pages).

In Situ 'Deliverability' Trials Using Calcium Polysulphide to Treat Chromium
Contamination at Shawfield, Glasgow. Following earlier field trials that indicated the
effectiveness of calcium polysulfide (CaSx) application in reducing Cr(VI) associated
with chromite ore processing residue, another field trial was conducted in 2009 to
identify the most effective CaSx delivery mechanism into the subsurface.The methods
investigated for CaSx delivery were (1) a groundwater recirculation system (which also
achieved situ flushing of contaminated soil); (2) direct-push injection using close grid
spacing; and (3) soil mixing. All three trials provided evidence of total Cr mobilization
as a combination of chemical-physical action (February 2013, 8 pages). View or
