Public Comment Period and Joint Public Hearing Concerning Proposed Delaware River Basin Commission Draft Docket and Department of Environmental Protection Draft NPDES Permit for Exelon Generation Company, LLC, Limerick Generating Station


[42 Pa.B. 4479]
[Saturday, July 14, 2012]

 The Delaware River Basin Commission (Commission) and the Department of Environmental Protection (Department) are accepting comments on the proposed approvals related to applications filed with each agency by Exelon Generation Company, LLC (Exelon Generation) for its Limerick Generating Station (LGS) located in Montgomery County. The Commission will accept written comments on its draft doc. D-1969-210 CP-13 through 5 p.m. on October 27, 2012. The Department will accept written comments regarding its proposed National Pollutant Discharge Elimination System (NPDES) Permit No. PA0051926 for the LGS facility until 5 p.m. on October 27, 2012. The agencies will hold a joint public hearing on August 28, 2012, (details as follows) on the proposed agency actions.

 LGS is located on a 491-acre site adjoining the east bank of the Schuylkill River, almost entirely within Limerick Township, Montgomery County, but with a small area extending into Lower Pottsgrove Township, Montgomery County. The site is about 1.7 miles south of the Borough of Pottstown. The LGS property includes 154 acres adjoining the west bank of the Schuylkill River in East Coventry Township, Chester County; however, no plant features of LGS are situated in this area. LGS is a nuclear power plant with two generating units, each having a maximum Reactor Thermal Power of 3,515 megawatts, with circulating cooling water for the steam turbine condensers furnished from cooling towers and surface waters. Noncontact cooling water and boiler blowdown are discharged to the Schuylkill River adjacent to the LGS facility.

 The Commission's draft docket sets forth the terms and conditions of the Commission's proposed approval for both water withdrawals and discharges associated with the LGS facility. It would authorize surface water withdrawals from the Schuylkill River or Perkiomen Creek, or both, including an increase in the peak daily withdrawal from the Schuylkill River from 56.2 million gallons (mg) to 58.2 mg (44 mg consumptive plus 14.2 mg noncon-sumptive) and restricts the maximum monthly withdrawal to 1.7422 billion gallons. The draft docket also approves Exelon Generation's use of water from Tamaqua Area Water Authority, Wadesville Mine Pool and the Delaware Diversion (by means of Forest Park Water Authority and Exelon Generation's Bradshaw Reservoir) to augment the proposed withdrawals. The draft docket would approve the discharge of noncontact cooling water and boiler blowdown to the Schuylkill River.

 The proposed NPDES permit would renew the Department's approval for the continued discharge by LGS of cooling tower blowdown, treated process wastewater and stormwater to the Schuylkill River and Possum Hollow Run through various outfalls.


 The public hearing will take place on Tuesday, August 28, 2012, from 6 p.m. until 9 p.m. and will be preceded by an information session, running from 4:30 p.m. until 5:30 p.m. Written comments will be accepted until 5 p.m. on October 27, 2012.


 The hearing and information session will take place in the Sunny Brook Ballroom, 50 Sunny Brook Road, Pottstown, PA 19464.

 Written comments must be addressed separately to each agency. Written comments to the Commission may be submitted at the hearing and may also be sent to or in hard copy to the attention of the Commission Secretary, DRBC, either by fax to (609) 883-9522 or to P. O.

Regardless of the method of submission, comments should include the name, affiliation (if any) and address of the commenter and the subject line, ''Public Comment—Exelon LGS Docket.''

 • Registration to testify. Individuals who wish to speak at the hearing will be asked to complete separate, pre-numbered Commission/Department commenter cards as appropriate and will be summoned to the microphone in the order that their card number is called. Registrations to present oral testimony will begin at approximately 4:30 p.m. on the day of the hearing and will continue until the hearing is closed. There will be no advance registration.

 • Time allowances. To allow everyone who wishes to speak an opportunity to do so, individuals will be allotted no more than 3 minutes each. Speakers will not be permitted to cede their time to others; however, after everyone who desires to speak has had a chance to do so, the hearing officer may accept requests from those who wish to supplement their earlier remarks.

 • Stenographic record. A court stenographer will be present during the public hearing to capture verbal comments for the public record.

 • Other. The sole purpose of the hearing on August 28, 2012, is to provide members of the public with an opportunity for oral testimony on the proposed Exelon Generation Company, LLC, Limerick Generating Station and Surface Water Augmentation approvals. The Department and the Commission will not respond to comments or conduct any other business during this hearing. The Commission will not accept oral testimony on its draft Exelon LGS docket at any other time, including at the Commission's regularly scheduled public meetings in September and December.

Project Description. A detailed description of the project is included in each of the two draft approvals.

 Briefly, the proposed Commission docket would:

 1. Provide long-term authorization for water withdrawal and discharge operations based upon experience gained from the LGS Water Supply Modification Demonstration Project and the Wadesville Mine Pool Withdrawal and Streamflow Augmentation Demonstration Project.

 2. Consolidate within a single docket all conditions relating to the surface water withdrawals required to meet consumptive and nonconsumptive needs at LGS, and the facility's surface water discharge to the Schuylkill River of up to 14.2 million gallons per day of blowdown. Until this time, Commission water withdrawal and discharge conditions had been included in multiple dockets.

 3. Approve an increase in the maximum daily withdrawal from the Schuylkill River by LGS from 56.2 mg to 58.2 mg (44 mg consumptive plus 14.2 mg non-consumptive) and establish a maximum monthly withdrawal of 1.7422 billion gallons. The project water withdrawals are located in the Schuylkill and Delaware River watersheds. The water withdrawals primarily will be made from the Schuylkill River but also will be drawn from the Wadesville Mine Pool and the Borough of Tamaqua Water Authority's Still Creek Reservoir (by means of releases to the Schuylkill from these impoundments) and the Perkiomen Creek. Water withdrawn from the Perkiomen Creek is augmented by a withdrawal from the Delaware River conveyed by means of the Point Pleasant Pumping Station and Bradshaw Reservoir.

 4. Eliminate the current restriction on withdrawals from the Schuylkill River when ambient water temperatures reach 59° F; reduce from 4 days to 3 the travel time required for water from some augmentation sources to reach LGS intakes; modify river and stream monitoring requirements; and continue the Restoration and Monitoring Fund.

 The proposed NPDES permit would renew approval for the continued discharge by LGS of cooling tower blowdown, treated process wastewater and stormwater to the Schuylkill River and Possum Hollow Run through various outfalls.

 Additional public records of the Commission relating to the draft docket are available for review consistent with Article 8 of the Commission's Rules of Practice and Procedure (RPP) governing public access to records and information. The Commission's RPP are also available on the Commission's web site,
