Dry Season = facilities sized for May 1 through September 30 loads but operate year round; year round = facilities sized for year round loads and operated year round. 2. The GHG Emissions are based on the flow and load reduction average over the project. The average flow and nutrient load reduction over the 10-year project duration for optimization and 30-year project duration for sidestream and upgrades. 3. Based on ammonia/nitrogen removal only. 4. Based on phosphorus removal only. * The plant is not removing additional phosphorus load during for the dry season optimization.
