Management of contaminated soils, including “urban fill” and soils impacted by a “release” (i.e., from a site with a confirmed release) and containing regulated contaminants (i.e., petroleum, hazardous materials), is a significant issue affecting development and construction projects in New Hampshire, with the potential to substantially increase costs due to the need for off-site transportation and disposal of these soils. In addition, these soils from New Hampshire as well as out-of-state sources, may be disposed or used as daily cover at New Hampshire landfills, filling disposal capacity that could otherwise be available for solid waste. Further, inappropriate use of these soils as fill could potentially result in adverse impacts to human health and the environment.

New Hampshire regulations (e.g., Env-Or 600 rules) require remediation (off-site disposal, on-site or off-site treatment) of soil impacted by a release resulting in concentrations of regulated contaminants above Soil Remediation Standards (SRS – pursuant to Env-Or 606.19). These impacted soils may also potentially be left in place if: a risk assessment demonstrates that they do not pose unacceptable risk, that the future use of the site is restricted by the establishment of Activity and Use Restrictions (AURs) that run with the property deed, and/or potential construction of containment structures/barriers (e.g., soil or asphalt cap). Env-Or 600 rules allow for the on-site management of release-impacted soils with contaminant concentrations below SRS (i.e., without the need for a risk assessment, AURs, containment); and exempt from the need for remediation, regulated contaminants that are due to “background conditions” pursuant to Env-Or 602.03, including so called urban fill soils. However, if these mildly contaminated soils or urban fill materials are excavated and moved off-site, then they are currently required to be disposed of at a permitted facility (Env-Or 611.06 (d)), currently restricted to a limited number of landfills and soil treatment facilities.

NHDES recognizes the need for clear regulatory options and is in the process of evaluating different approaches it may take to manage such impacted soils. As part of this effort, NHDES has established the Mildly Contaminated Soil (MCS) Work Group to provide a forum for discussion regarding the management of mildly contaminated soils and urban fill materials. In addition, NHDES is part of the Northeast Waste Management Officials Association (NEWMOA) Contaminated Soils Management Workgroup whose mission is to understand how mildly contaminated soils are currently regulated and managed by each member state (the 6 New England states, NY, NJ) and develop common reuse options and policies.

For this EBC New Hampshire Chapter program, speakers will include regulators from NHDES and the Massachusetts Department of Environmental Protection, as well as practitioners from environmental consulting/contracting, construction, and waste management facilities who will be discussing their experience and perspective on the management of these impacted soils.

Continuing Education Certificates are awarded by the EBC for this program (3.5 training contact hours). Please select this option during registration if you wish to receive a certificate.
