Case: Mosquito Bay, Louisiana
Release: Between 100,000 and 126,000 gallons of natural gas condensate oil
The Trustees, in cooperation with the responsible party and its
representatives, conducted a pre-assessment and an injury assessment to
determine the nature and extent of potential injuries to trust resources in
Mosquito Bay associated with the pipeline discharge. Analyses of source oil
samples, shoreline habitat, water samples, sediment samples, and field
observations were used to assess the ecological impact from the oil discharge.
The total area of marsh affected by the incident was 106.0 acres. 12.7 acres of
marsh sediments and vegetation were directly affected by natural gas condensate
oil and a controlled burn. An additional 93.3 acres were not affected by
natural gas condensate oil, but were affected by the burn after the fire
escaped its planned boundaries and burned the marsh vegetation.
