Management of mildly contaminated soils (MCS), including “urban fill”/background soils impacted by regulated contaminants from non-point sources, and soils impacted by point source releases at concentrations below NHDES Soil Remediation Standards (SRS), is a significant issue affecting development and construction projects in New Hampshire, with the potential to substantially increase costs due to off-site transportation and disposal of these soils.
NHDES regulations (Env-Or 600 rules) exempt from remediation, soils impacted by regulated contaminants that are due to “background conditions” including non-point sources; and allow for the on-site management of release-impacted soils with contaminant concentrations below SRS. However, if these mildly contaminated soils are removed off-site, then they are currently required to be managed at “an authorized treatment or disposal facility holding all requisite federal, state, or local permits, licenses, or approval” pursuant to Env-Or 611.06 (d).
In addition to the costs associated with off-site transport and disposal/treatment of these MCS, which may be sourced from New Hampshire or out-of-state, other important considerations include filling landfill disposal capacity that could otherwise be available for general solid waste, and the inappropriate use of these soils as fill that could potentially result in adverse impacts to human health and environmental degradation.
This program will highlight the current state of MCS in New Hampshire, including the considerable progress that has been made in the last year or so towards development of an effective management strategy and guidelines for the handling and disposition of these soils. Speakers will include representatives from NHDES and NHDOT, as well as practitioners from environmental consulting/contracting, and environmental attorneys.
