1. The Future of Sludge Disposal: A Fresh Perspective after Sandy Jim Meehan – Executive Director Rahway Valley Sewerage Authority

2. Recent Plant Upgrade Recently completed a plant expansion, including: Increased pumping capacity based on 100 year storm Raised grade along river approximately 10 feet Upgraded backup electric including a Cogeneration facility, allowing us to go on “Island Mode” for 16 days during Superstorm Sandy (Approximate Construction Cost: $170M)

3. Storm Response Considerations Additional Storage Tanks; think outside the box: Utilize offline primary or secondary tanks Temporarily increase SVI in secondary Plan for out of state disposal sites Modify bid specifications for sludge disposal/hauling to include alternate

4. Review Possible Last Resort Options Disposal at garbage incinerator facilities – Establish which facilities are available to a plant – Review any technology limitations to accepting biosolids. – Review permit barriers and weather emergency approvals would be possible. Begin discussions with appropriate agencies. Onsite open air storage of dried/dewatered biosolids – Establish a location suitable for storage – Review storm water protection measures required

5. Conclusions: Advanced preparation will save time during emergency: » Plan a temporary thickening/dewatering scenario Involve vendors early to establish a plan of action and have the required utilities and piping connections available » Review options for power generation and establish backup locations where temporary generators can be connected to critical equipment May not be able to use plant distribution. Have equipment and/or building specific utility connection options.
