- Monitor effluent levels and change out Carbon Units as appropriate.
- Plan to collect another product sample for verification purposes per request of USCG NPFC.
- Need to control constant algae buildup.  Received approval from State and City to inject EPA approved biocide to remove the algae inside of each well.
- Pump out 1,000 gallon AST as needed.
- Operate groundwater depression and oil recovery systems.

***** Continue to collect water quality samples of the effluent.
***** Continue operation and maintenance plan for the product and groundwater systems.
***** Replace Carbon Units per water quality sample results.

EPA will operate these systems for another 6 months and then re-evaluate.

*****EPA completed a revised Oil Removal Action Plan increasing total site costs from $495,000 to $590,000 to cover an additional six months of oil removal.  
*****The pumps and treatment system are continuing to be fouled by algae buildup.  Received approval from State and City to implement mitigation options.
