Project I: Characterization of Aquaculture Effluent, Environmental Impact Assessment for Effluent from Hawaiian Aquaculture Facilities

  1. Compile and review the pertinent federal, state, and local regulations applicable to aquaculture discharges.
  2. Categorize discharges based on the organisms being cultured and the culture system design.
  3. Compile existing data for representative culture systems and acquire new data as required.
  4. Characterize the quality of effluents discharged from typical Hawaiian aquaculture facilities in terms of chemical species, concentrations, and mass loadings.
  5. Perform a case study for an actual aquaculture facility.
  6. Categorize potential receiving waters for aquaculture discharges on the basis of their physical, chemical, and biological characteristics.
  7. Project the quality and quantity of discharge effluents from a range of typical aquaculture facilities.
  8. Assess the potential for environmental impact, whether positive, negative, or negligible, of the aquaculture effluents discharged into a variety of receiving waters in order to determine the combinations of facility design and discharge locations which present the optimal impact scenarios.

Project II: Effluent Treatment Processes

The overall goal of this component is to produce a state-of-the-art detailed baseline reference document “Engineering Opportunities and Constraints in the Treatment of Aquaculture Effluent.” General long-term objectives are to provide cost-effective aquaculture effluent discharge treatment technology as necessary to satisfy discharge limit regulations, and to obtain required operating permits. It is understood that the treatment process will vary with effluent characteristics and site discharge assimilation capacity as evidenced by environmental impact.

Project III: Education and Regulation Modification

This component has the singular objective of fostering a dialogue between aquaculturists, public regulators, and policy makers leading toward increased understanding and consideration of environmental regulations governing aquaculture effluent discharges into the environment. This proposal is targeted for one year, with proposed subsequent action for a second year.
