OVERVIEW<br />
<strong>FY</strong> <strong>2010</strong> Major Recommended Activities <strong>and</strong> Changes<br />
• Maintain full compliance with the National Pollutant Discharge Elimination Systems (NPDES) permit<br />
• Actively participate in chemicals procurement to ensure lowest cost<br />
• Continue to minimize Plant <strong>and</strong> biosolids odor<br />
• Continue implementation of operator cross training <strong>and</strong> wastewater treatment operator trainee programs<br />
• Continue implementation of High Priority Rehabilitation Program to ensure critical process equipment remains in service<br />
• Continue operation of treatment facilities during construction of the following Capital Improvement Program (CIP) projects:<br />
- Filtration & Disinfection Facilities Upgrade Phase II - scheduled for completion in calendar year <strong>2010</strong><br />
- Process Control Computer System (PCCS) - partially operational since <strong>FY</strong> 2005<br />
- Raw Wastewater Pump Stations I - scheduled for completion in <strong>FY</strong> <strong>2010</strong><br />
- Nitrification/Denitrification Facilities Upgrade - scheduled for completion in <strong>2011</strong><br />
- Biological Sludge Thickening - scheduled for completion in 2012<br />
- Digester Demolition <strong>and</strong> Site Preparation - scheduled for completion in <strong>2011</strong><br />
• Continue to conduct wastewater treatment process research <strong>and</strong> development in various areas including:<br />
- Optimization of chemical phosphorus removal<br />
- Digestion process hydrolysis<br />
- Side-stream treatment for nitrogen removal<br />
- Biosolids product quality improvement<br />
• Continue to work with surrounding jurisdictions (Maryl<strong>and</strong> <strong>and</strong> Virginia) on regulatory requirements for biosolids <strong>and</strong> l<strong>and</strong><br />
applications<br />
<strong>FY</strong> <strong>2011</strong> Major Recommended Activities <strong>and</strong> Changes<br />
• Continue to implement the liP recommendations to improve Plant efficiency <strong>and</strong> effectiveness<br />
• Continue operation of treatment facilities during construction of the following CIP projects:<br />
- Process Control Computer System<br />
- Nitrification/Denitrification Facilities Upgrades - scheduled for completion in <strong>2011</strong><br />
• Continue to conduct wastewater treatment process research <strong>and</strong> development<br />
Impact of Capital <strong>Proj</strong>ects on <strong>FY</strong> <strong>2010</strong> <strong>and</strong> <strong>FY</strong> <strong>2011</strong> <strong>Operating</strong> Expenditures<br />
• Full implementation of dissolved oxygen (DO) control in secondary treatment will reduce energy consumption<br />
• Fine bubble aeration in the nitrification process will enhance aeration process efficiency <strong>and</strong> reduce energy consumption
