          This Internet seminar will focus on two case studies where
          ecological revitalization principles were practiced.


The Atlas Tack Superfund Site: An Example of Ecological Enhancement as
Part of Waste Site Remediation
Presenters: Elaine Stanley, Remedial Project Manager, EPA Region 1 and
Ken Finkelstein, NOAA

      Adjacent fresh and salt water wetlands were heavily contaminated
by discharge and fill of metal plating and enameling waste from the
Atlas Tack Superfund site, Fairhaven, MA . The site is situated
approximately 500 m northwest of Buzzards Bay, designated as an Estuary
of National Significance. The remedy includes the removal of nearly 5.5
acres of wetlands; the subsequent mitigation includes vital ecological
enhancements that will eliminate much invasive Phragmites vegetation,
develop a new fresh water marsh, reintroduce salt marsh to those areas
disturbed, and provide a means to eliminate storm water flooding.
      As part of the planning for the ecological enhancements, EPA made
use of National Oceanic and Atmospheric Administration (NOAA)'s Damage
Assessment and Restoration Program (DARP) who act as a Federal natural
resource trustee. NOAA contributed to the development of the sediment
remedial goals, the wetland removal plan, and greatly assisted the
design the mitigation resulting in ecological enhancements at no
additional cost to EPA.
      At the Atlas Tack site, the specific enhancements include the
removal of contaminated fill and the construction of a dike in the
northern wetland that will create new fresh and salt water marshes. The
EPA contractor, the Army Corps of Engineers (ACOE) and NOAA have jointly
designed separate fresh and salt water marshes that will out-compete the
Phragmites, provide a means to allow storm water to promptly discharge
into the estuary, and create additional estuarine habitat. This
Superfund site has used normal remedial funding to create a remedy that
enhances the previous ecology while working cooperatively with three
Federal agencies.

The Cache La Poudre River Site
Presenter: Paul Peronard, On-Scene Coordinator, EPA Region 8

      Encompassing 19 acres along a popular recreational waterway in
Fort Collins, Colorado, the Poudre River Site has proved to be an
interesting and unique cleanup for the EPA Removal Program. Polycyclic
aromatic hydrocarbons (PAH) have been observed in the soils of a former
gas plant, in the groundwater underneath a closed landfill, and in the
sediments of the Poudre River itself. The contaminants are likely the
remnants of former coal to gas processes. The cleanup and protection of
the Poudre River involves such intricacies as the creation of a barrier
wall, the redirection and treatment of contaminated ground water, and
the replacement of non-native vegetation with native species.


                 We look forward to your participation!
