Option 2 -Install Emissions Controls on Units 3 & 4 Option 2 could be adopted if EPA kept to its present regulations. Emissions controls could be placed on the Cooper-Bessemer engine and the large Worthington engine. The two smaller Worthington engines could be designated Emergency Units To place emissions controls on Units 3 & 4 would require a cost of $400,000. In 2010, the two units provided capacity credits of $309,936, plus reimbursements for fuel and labor for URGE tests. If ERMU were faced with the choice of putting on the emissions controls, or losing the engine credits, the choice should be to install the emissions controls because the payback would be about 15 months. The emissions controls on each Unit would include a combination direct oxidation catalyst and exhaust silencer to take the place of the existing exhaust silencer. The new system must include a closed crankcase ventilation system, or filtered open crankcase system. An emissions monitoring system must be installed with ongoing emissions records kept at the job site. Approved low sulfur fuel oil must be used in the diesel. After the conversions are completed, testing needs to be done to reduce emissions by 70%, or to 23 ppmvd. All units must be compliant with NESHAP by 5/3/2013. Option 3 -Install Emissions Controls on Units 1 & 2 Under Option 3, the same package of emissions controls that are described above for Units 3 & 4 would be installed for Units i & 2. Because Units 1 & 2 are slower in speed and are smaller, the cost/KW of emissions controls would be higher. To install emissions controls on Units 1 & 2 would require a total expenditure of $110,000. In 2010, Units 1 & 2 provided capacity credits of $42,504, plus reimbursement for fuel and 12
