• Grounding and lightning protection • Heat tracing • Cathodic protection E1 Site Development Re-powering Study for the Northport and Port Jefferson Power Stations Appendix VII Northport Capital Cost Estimate Descriptions This account includes the following required for new combined cycle equipment: • Subsurface investigation • Site preparation • General excavation and backfill • Piling • Erosion control • Roads and parking • Fencing • Landscaping • Drainage • Row of lighting poles to the north of existing road to be relocated (if required) to the new road. • Buried communication line (possibly fiber optic) that runs north from a utility pole on the north side of the existing road. • Miscellaneous buried conduits that run north (or northwest) from a utility pole on the southeast corner of the area. • Storm drain on the north edge of the area. • The existing recharge basin at the northwest corner of the area will be relocated F1/F2 Water/Wastewater Treatment Area The area includes: • Makeup water supply and treatment systems consisting of two 100-percent makeup water supply pumps, two-100% (130 gpm each) RO systems with electro deionization and including a 1,000,000 gallon storage tank for demineralized water. The tank will provide approximately 20 hours of storage when firing distillate oil and approximately 5 days of storage with natural gas firing. • Wastewater treatment for boiler blowdown, equipment washes, wastes and oily wastes from equipment area drains; will be directed to the existing wastewater treatment facility. Drains for plant equipment areas will be directed to oil/water separator(s) prior to discharge. Reject water from the RO system will be directed to the inlet lagoon. • It is assumed that the existing septic system(s) serving Unit 4 will be reused. A new septic system is included for sanitary waste from the new administration building. March 30, 2009 248
