Data Source and Calculation

Pounds of nutrients discharged each calendar year is obtained from permit data available in Comprehensive Environmental Data System (CEDS). It is then compared to the baseline data, collected during calendar year 2004.

201022,426,587.93There are three reasons why the nitrogen loads have decreased below the short-term target, and are very close to the long-term target: Installation of nitrogen removal facilities has proceeded on a expedited schedule; Operation of the installed facilities is better than design expectations; and, Wastewater flows remain below design capacity for most of the facilities. Design capacity was the basis for establishing the load target at each facility. As population increases in the future, flows will approach design capacity and operational efficiencies will also approach design efficiencies. Reporting period is identified as the calendar year, ending December 31. Updates are expected in May, annually. Data from earlier years was provided to give a historical context for the nutrient loading numbers provided.
