      • Louisiana Oil Spill Prevention and Response Act of 1991 (OSPRA)
  • NRDA Regulations
      • Federal – January 1996
      • State – March 1999
  • Goal of NRDA

To make the environment and public whole for injuries to natural resources and services resulting from an incident involving a discharge or substantial threat of a discharge of oil

Preassessment Workplans

“Aerial Surveys for Assessing Marine Mammals and Sea Turtles in the Region of the Mississippi Canyon 252 Incident“

  • Purpose:
      • Estimate abundance & distribution of marine mammals & sea turtles in coastal waters
      • Document occurrence of oil in coastal waters
      • Document oil exposure, distribution changes, & behavior changes of marine mammals & sea turtles
  • Data Collected:
      • Sightings of Species (Quantity &Location)
      • Environmental conditions (i.e., sea state, temperature)
      • Oil Slick Location

“Deepwater Horizon/MC252/BP Shoreline/Vegetation NRDA Pre-Assessment Plan”

  • Purpose:
      • Determine shoreline areas exposed to oil
      • Characterize exposed shorelines (habitat, vegetation and fauna)
      • Identify monitoring Stations for Injury Assessment
  • Data Collection
      • Delineate spatial extent and degree of oiling
      • Describe observed impacts to vegetation and biota
      • Oil sample collection

“Work Plan for Estimating Secretive Marsh Bird Mortality Deepwater Horizon (MSC 252) Oil Spill NRDA Bird Study #3”

  • Purpose:
      • Quantify abundance & density of secretive marsh bird species in un-oiled representative habitats
      • Quantify proportion of live oiled & live un-oiled birds in representative habitats through active capture of live individual birds
      • Estimate representative marsh bird mortality rates using radio telemetry
      • Quantify fiddler crab burrow densities to supplement our understanding of marsh-specific rail densities
  • Data Collection
      • Point counts &playback surveys
      • Fiddler crab densities
      • Radio Telemetry of adult rails and seaside sparrows

“Water Column Injury Ephemeral Data Collections Deepwater Horizon Oil Spill Plan for Adaptive Water Column Sampling Cruise Plan- American Diver 1 & Ocean Veritas 9”

  • Purpose:
      • Obtain near-field data on oil droplet size, water chemistry (oil and dissolved hydrocarbon concentrations), and other particulate (detritus, marine snow, plankton) densities
  • Data Collection
      • Salinity, temperature &water density, dissolved oxygen, and fluorescence
      • Oil droplet size distributions and concentrations
      • Concentrations of suspended sediments and detritus
      • Plankton concentrations (live and dead)
      • Pyrosomes
