Annual Operating Cost Summaries for 



Alternative 2: Semifixed Plant 



Actual Indian River Inlet annual operating costs (provided by Mr. Robert Henry of the Delaware 

 Department of Natural Resources and Environmental Control (DNREC)) averaged for the 5-year 

 period from 1990 through 1995 (attached) are used as a guide for estimating the annual costs for 

 Shinnecock Inlet. Assumptions and rationale are described below. 



a. For a three-person operating crew, average annual costs are $104,200 (average of $34,733 

 per person). Comments from U.S. Army Engineer District, New York, have suggested 

 that $35,000 cost per person including overhead is too low and should be approximately 

 doubled. Therefore, Shinnecock costs for a five-person crew are $350,000. 



b. Electric utilities for the operations building should be approximately equal; therefore, use 

 $1,000. 



c. Plant fuel (diesel for pumps (two) and crane) averages $8,000. At Shinnecock, assume 

 $4,000/year/pump, so with three pumps (supply, primary booster, one extra booster), use 

 $12,000. 



d. Vehicle fuel averages $600/year at Indian River Inlet. Because of increased driving due 

 to multiple booster pumps, use $1,200. 



e. At Indian River Inlet, Contract Services, Supplies and Material (CS, S&M) averages 

 $27,000/year. This category is for miscellaneous (catch-all) costs. Assume because of 

 the complexity of multiple boosters and longer pumping distance that this cost is double 

 for Shinnecock. Use $54,000.
