2009 & 2010 Biosolids Report
Regulatory Issues
In 2010, the FDEP notified OCU that Shelley’s Environmental Systems’ operating permit for its
residual facility would not be renewed. To avoid any interruption in operation and to maintain
compliance with regulations, the OCU management team initiated a temporary contract arrangement
with N-Viro Florida to haul and process biosolids generated at the EWRF and the NWRF. This facility
produces a stabilized product called N-Viro Soil, which is distributed and marketed as fertilizer in
Central Florida. As an alternative, arrangements were also made with the Orange County Landfill for
accepting the biosolids produced at the EWRF and the NWRF. Later, Shelley’s Environmental
Systems received its operating permit with an administrative order.
In accordance with state of Florida and Orange County procurement procedures, OCU solicited for a
contractor for hauling, processing, and land applying the biosolids produced at the EWRF and the
NWRF and again awarded the contract to Shelley’s Environmental Systems. The contract with
Shelley’s Environmental Systems now includes additional conditions to ensure compliance with the
contract provisions.
Management Support
The management team is committed to following the NBP’s Code of Good Practice in managing its
Biosolids EMS. This has allowed OCU to continue to make progress in meeting the Biosolids EMS
goals and implementing best management practices. Several projects, including a biosolids quality
enhancement project at the EWRF, a biogas energy recovery project at the SWRF, and a new master
plan to address short-term and long-term needs, were recently initiated. The management team
supports proactive maintenance strategies for an efficient and effective Biosolids EMS.
2011 Goals
• Maintain 100% beneficial reuse.
• Continue to maintain compliance with all applicable regulatory and certification requirements.
• Improve the quality of biosolids by installing centrifuge dewatering systems at the EWRF.
• Increase skill levels of operators with regard to biosolids operations.
• Complete interim audits in accordance with the NBP’s requirements.
