(3) Additional long-term studies and monitoring requirements to 

 ensure that effects, if any, to listed species are detected 

 and mitigated prior to the development of conditions that 

 could lead to jeopardizing the continued existence of any of 

 these species; and 



(4) Additional permit conditions to minimize any adverse effects 

 to listed species and marine habitat. 



Specific conservation recommendations contained in the biological 

 opinion include: 



• The U.S. Geological Survey hydrodynamic dilution model under 

 stratified conditions should be completed and reviewed prior 

 to discharge. 



• EPA should provide NMFS with a detailed characterization of 

 the effluent and the reaction of its contaminants with sea 

 water. Additionally, information regarding particulate and 

 toxic transport, re-suspension, and accumulation should be 

 evaluated to identify long-term depositional sites. 



• Studies should be conducted to provide information on the 

 distribution and composition of plankton patches in 

 Massachusetts and Cape Cod bays and to provide predictive 

 information on the effects of the proposed discharge.
