The Agencies developed a restoration plan for the resource injuries caused by
the spill. That plan is found within the Final Damage
Assessment and Restoration Plan and Environmental Assessment for the
December 7, 1997 Alafia River Spill released in 2000. The Agencies recovered
the anticipated costs to implement the restoration actions outlined in that
plan in a 2003 settlement with the Mulberry Phosphates, Inc. (MPI) and its
insurer. The restoration actions identified in that plan are expected to
improve the health of the Alafia River and the Tampa Bay watershed by restoring
and creating wetlands and productive fisheries habitat, and increasing fishery
abundance.
The Agencies will monitor these projects to ensure that they restore the
natural resources harmed by the release. Moreover, these projects will help
improve scientific understanding of habitat restoration, so that future
environmental problems - whether from acidic releases or other causes - can be
mitigated.
The restoration actions identified in that plan are:
Project: Release of juvenile snook into Alafia River
Status: Completed in 1998
This fish release project was undertaken in 1998 to directly replace snook in
the Alafia River, in order to partially offset the spill’s kill of similar
sized snook. In April 1998, Agencies were notified of the availability of a
limited number of juvenile snook suitable for potential release into the Alafia
River. The fish had been reared at the Florida
Department of Environmental Protection's
Stock Enhancement Research Facility and pending funding for transport, were
ready to be returned to the Alafia River. The fish were transported, acclimated
and released into the Alafia on May 22, 1998 after being tagged and passing a
health certification. A total of 154 snook averaging 11 inches in length were
released in six locations between the I-75 Bridge and the mouth of the river
and six locations east of the bridge.
Project: Freshwater wetland restoration
Funding: $2.3 million (from MPI settlement)
Status: In planning phase
At least 18 acres of freshwater habitat will be created by converting
non-native uplands, such as agricultural lands or filled historic riverine
habitat, into freshwater floodplain wetlands, or by returning disturbed
vegetative communities to an original or more desirable wetland community
structure.
Projects of this nature will restore higher quality wetland vegetation and
provide a comparable array of ecological services as the freshwater wetlands
that were injured. Restoration of freshwater wetlands will, over time, also
help remove amounts of nitrogen similar to the amounts added to the system due
to the release.
The funding for this project includes estimated costs for site identification,
land acquisition (if needed), permitting, construction, performance monitoring,
and any mid-course corrections needed to ensure restoration success.
FDEP and the FWS are leading this planning effort.
Project: Estuarine wetland restoration and oyster reef creation
Funding: $1.3 million (from MPI settlement)
Status: In planning phase
The goal of the estuarine wetland restoration and oyster reef creation project
planning effort is to create at least four acres of oyster reef habitat and
restore at least four acres of estuarine wetlands (or equivalent combinations)
in the lower Alafia River or nearby areas of Tampa Bay. Estuarine wetlands and
oyster reef are each productive fisheries habitats and projects of both types
will be used to replace the fishery biomass lost. Projects of these types
will also benefit birds-which depend on fish as a food source, the water
column-as oyster reefs assist in removing suspended sediments from the water
column, benthos-as wetlands provide productive habitat for benthic organisms,
and recreational anglers-who depend on fish for their catch.
Wetland restoration projects may involve converting non-native uplands or
previously filled wetlands into tidally influenced habitat, or replacing
nuisance or exotic-dominated vegetation communities in estuarine areas with
more productive estuarine vegetation.
Oyster reef creation projects will involve the placement of hard substrate in
open water, on shoreline or in intertidal areas to create three-dimensional
structure suitable for colonization by oysters. Created reef areas will enhance
the availability of prey items, create new foraging opportunities for fish and
other aquatic fauna, and enhance fisheries production.
The funding for this project includes the estimated costs of site
identification, land acquisition (if needed) , project design, permitting,
construction, performance monitoring, and any mid-course corrections needed to
ensure restoration success.
FDEP and the NOAA are leading these planning efforts.
