Piney Point ITN
• Preference for proposals that use proven and tried
methods, and higher ranking given to plans that
minimize ammonia nitrogen loadings to surface
waters.
• Respondents can utilize DEP water management
plan or develop their own.
Late 2006/Early 2007
Water Management Plan
• After site closed process water will consist
of 0.3 MGD seeping from the closed stacks
• Potential Post Closure Water Management
Options
• Spray Evaporation
• Spray Irrigation
• Tie in to Manatee County sewer
