The Commission's Rules of Practice require all intervenors filing documents with the Commission to serve a copy of that document on each person on the official service list for the project. Further, if an intervenor files comments or documents with the Commission relating to the merits of an issue that may affect the responsibilities of a particular resource agency, they must also serve a copy of the document on that resource agency.

k. This application has been accepted and is ready for environmental analysis at this time.

l. The existing Conowingo Project consists of a concrete gravity dam with a maximum height of approximately 94 feet. The dam consists of a 1,225-foot-long, non-overflow gravity section, a 2,385-foot-long ogee-shaped spillway section, a 950-foot-long intake-powerhouse section, and a 100-foot-long non-overflow gravity section. The spillway consists of a 2,250-foot-long section with a crest elevation of 86.0 feet, and a 135-foot-long section with a crest elevation of 98.5 feet.[1] The Start Printed Page 26344spillway is fitted with 50 Stoney-type crest gates and two regulating gates. Each Stoney crest gate is 22.5 feet high by 38 feet wide and has a discharge capacity of 16,000 cubic feet per second (cfs) at a reservoir elevation of 109.2 feet. The two regulating gates are 10 feet high by 38 feet wide and have a discharge capacity of 4,000 cfs per gate at a reservoir elevation of 109.2 feet.

Conowingo dam impounds the Susquehanna River, forming Conowingo reservoir (Conowingo pond) that extends 14 miles upstream from the dam. Total storage in the 9,000-acre reservoir is approximately 310,000 acre-feet, and total useable storage is about 71,000 acre-feet at the normal full pool elevation of 109.2 feet. The elevation of the normal river surface below the dam is approximately 20.5 feet. The impoundment provides approximately 89 feet of gross head for power generation purposes.

The power plant is integral with the dam and is composed of 13 turbine-generator units, draft tubes, and transformer bays. The first seven turbine-generating units (1-7) are completely enclosed within the powerhouse, and the last four units (8-11) are located outside. The hydraulic equipment for units 1-7 consists of Francis-type single runner hydraulic turbines. The hydraulic equipment for units 8-11 consists of four mixed-flow Kaplan-type hydraulic turbines. Units 1, 3, 4, 6 and 7 have 47.7-megawatt (MW) generators; Units 2 and 5 have 36.0-MW generators; and Units 8-11 have 65.6-MW generators. Additionally, two house turbines provide station service and “black-start” capability with each unit having a 1.6-MW generator. Water flowing through the turbines is discharged via the draft tubes into the tailrace immediately downstream of the dam.

Electricity generated at the project is transmitted by two individual 220-kilovolt (kV) transmission lines extending from the project substation to East Nottingham.

The Conowingo Project has an authorized nameplate generating capacity of 573 MW and generates an average of 1,836,125 megawatt hours annually. Exelon is not proposing any new or upgraded facilities or structural changes to the project at this time. Exelon is proposing to modify the project boundary in the vicinity of upper Broad Creek and downstream of the Conowingo dam. This modification will remove lands from upper Broad Creek, as well as downstream of Rowland Island. Originally included in the construction plans of the project, Exelon states these lands are no longer necessary for project operation. In addition, Exelon has engaged interested stakeholders to participate in the development of a comprehensive settlement agreement based on collaborative negotiation of specific terms and conditions for the new Conowingo license.
