UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 September 16, 2011 Mr. Chris Firestone Pennsylvania Department of Conservation & Natural Resources Bureau of Forestry - Plant Program Forest Advisory Services P.O. Box 8552 Harrisburg, PA 17105-1673

SUBJECT:

REQUEST FOR LIST OF PROTECTED SPECIES WITHIN THE AREA UNDER EVALUATION FOR THE LIMERICK GENERATING STATION, UNITS 1 AND 2, LICENSE RENEWAL APPLICATION REVIEW (PNDI NUMBER: 21136)

Dear Mr. Firestone:

The U.S. Nuclear Regulatory Commission (NRC or the staff) is reviewing an application submitted by Exelon Generation Company, LLC (Exelon), for the renewal of the operating license for Limerick Generating Station, Units 1 and 2 (Limerick). Limerick is located in Limerick Township of Montgomery County, PA, and is approximately 35 miles upriver of Philadelphia.

The application for renewal was submitted in a letter dated June 22, 2011, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) Part 54.

The NRC has established that, as part of the staff's review of any nuclear power plant license renewal application, a site-specific Supplemental Environmental Impact Statement (SEIS) to its "Generic Environmental Impact Statement for License Renewal of Nuclear Plants,"

NUREG-1437, will be prepared under 10 CFR Part 51, the NRC's regulation that implements the National Environmental Policy Act of 1969, as amended. The SEIS includes an analysis of pertinent environmental issues, including endangered or threatened species and impacts to fish and wildlife. This letter is being submitted under the provisions of the Endangered Species Act of 1973, as amended, and the Fish and Wildlife Coordination Act of 1934, as amended.

Limerick is a two-unit site with forced-circulation General Electric boiling-water reactors. The facilities consist of the reactor enclosures, turbine enclosures, cooling towers, electrical substations, independent spent fuel storage installation, Schuylkill River Pumphouse, and spray pond. Additional facilities are the cooling-tower blowdown discharge line and associated structures, which are submerged immediately downriver from the Schuylkill River Pumphouse.

The Limerick plant site contains a total of 645 acres, including 491 acres in Montgomery County and 154 acres in Chester County. The proposed action includes the use and continued maintenance of existing plant facilities and transmission lines. See Enclosures 1 - 5 for figures of the facilities and transmission lines. Exeion states that it has no plans for refurbishment or replacement activities to support renewal of the operating licenses.

As part of the SEIS preparation, the applicable transmission line corridors will be reviewed. The Limerick transmission system is comprised of the transmission lines and associated structures from the three main power transformers of Limerick Unit 1 to the Limerick 230-kV Substation, and the three main power transformers of Limerick Unit 2 to the Limerick 500-kV Substation:

both SUbstations are located on the plant site. The system also includes the substations,

C. Firestone - 2 transmission lines, and associated structures to connect Limerick to the regional electricity grid, including:

  • two 230-kV lines, designated 220-60 and 220-61, connecting the Limerick 230-kV Substation to the Cromby Substation located at Exelon Generation's Cromby Generating Station;
  • one 230-kV line, designated 220-62, connecting the Cromby SUbstation to the North Wales Substation and the regional electricity grid;
  • one 230-kV line connecting the Cromby Substation to the Plymouth Meeting Substation and the regional electricity grid, consisting of:

o One segment, designated 220-63, connecting the Cromby Substation to the Barbadoes Substation; and o One segment, designated 220-64, connecting the Barbadoes Substation to the Plymouth Meeting Substation; and

  • one 500-kV line, designated 5031, connecting the Limerick 500-kV Substation to the Whitpain Substation and the regional electricity grid.

Additionally, the transmission system includes the rights-of-way (ROWs) for the transmission lines. These ROWs were either pre-existing at the time Limerick was built (Le., the lines are being shared with other linear features that were already in place) or were added in conjunction with construction. The system is basically the same as originally constructed. See Enclosure 5 for an overview of the transmission line ROW routes, which traverse Montgomery County and Chester County.

The four offsite 230-kV lines exclusively serve Limerick, Unit 1, and the one offsite 500-kV line exclusively serves Limerick, Unit 2. Exelon states in the LRA, U[e]ven though these lines were constructed solely to serve the Limerick units, it is anticipated that some or all of these lines would continue to be used for transmitting electriCity produced by other generating sources even if the Limerick operating licenses are not renewed."

PECO, the energy delivery subsidiary of Exelon Corporation serving retail customers in southeastern Pennsylvania, owns in fee the offsite substations and a portion of the transmission line ROWs associated with the transmission system. A significant portion of the transmission system is located over or under highways, streets, other public places or property owned by others, for which PECO has permits, grants, easements, or licenses.

To support the SEIS preparation process and to ensure compliance with Section 7 of the Endangered Species Act, the NRC requests a list of species and information on protected, proposed, and candidate species and critical habitat that may be in the vicinity of Limerick and its associated transmission line ROWs. The applicant, Exelon, corresponded with your office by letter dated January 19, 2011. You replied by letter dated March 9, 2011 (PNDI Number: 21136), with a list of plant and terrestrial invertebrates species, and natural communities and geologic features potentially occurring in the vicinity of the plant and its associated transmission line ROWs. To avoid any duplicaton of effort, you may confirm that the list previously provided to Exelon from your office is still current rather than compiling a new list.

If any information is

C. Firestone -3 not current, please provide any applicable updates. Both the January 2011 letter from Exelon and the March 2011 letter from The Pennsylvania Department of Conservation and Natural Resources are enclosed for your reference. In addition, please provide any information you consider appropriate under the provisions of the Fish and Wildlife Coordination Act.

The NRC staff plans to hold two public license renewal overview and environmental seeping meetings on September 22, 2011, in the area of Limerick. The first session will be held in the afternoon and an identical session will be held later that evening. Both sessions will be held at the Sunnybrook Ballroom, 50 North Sunnybrook Road, Pottstown, PA 19464. The afternoon session wi" be from 2:00 p.m. until 4:00 p.m. and the evening session will be from 7:00 p.m.

until 9:00 p.m. In addition, the NRC plans to hold a one hour Open House prior to each meeting to answer public questions. You and your staff are invited to attend the public meetings and Open House. Your office will receive a copy of the draft SEIS along with a request for comments. The anticipated publication date for the draft SEIS is August 2012.

The Limerick license renewal application is available on the internet at http://www.nrc.gov/reactors/operating/licensing/renewal/applications/limerick.html. If you have any questions or require additional information, please contact Mrs. Lisa Regner, License Renewal Project Manager, by phone at 301-415-1906 or bye-mail at Lisa.Regner@nrc.gov.

Box 8552 Harrisburg, PA 17105-1673 Re; Renewal of Operating Licenses for Limerick Generating Station, Units 1 and 2 Request for Information on Listed Threatened and Endangered Species Dear Ms. Firestone; In mid-2011, Exelon Generation Company, LLC (Exelon Generation; a subsidiary of Exelon Corporation) plans to apply to the U.S. Nuclear Regulatory Commission (NRC) for renewal of the operating licenses for Limerick Generating Station, Units 1 and 2 (LGS). The existing license for Unit 1 will expire on October 26, 2024 and the existing license for Unit 2 will expire on June 22,2029. The renewal term for each unit would be an additional twenty years beyond the existing license expiration date.

The NRC requires that license renewal applications include environmental reports assessing potential environmental impacts from license renewal activities. One such impact would be effects of license renewal activities on threatened and endangered species that are listed or proposed for listing in accordance with the Endangered Species Act (ESA) (16 USC 1531, et seq.) (10 CFR 51.53(c)(3)(ii){E>>. Accordingly, we are contacting you to obtain input for use in addressing these effects in the LGS license renewal environmental report. Later, NRC may also request an informal consultation with your office consistent with Section 7 of the ESA (16 USC 1536(a>>.

Project Features LGS existing features that are relevant to the effects of license renewal on threatened and endangered species include the following; Enclosure 7

Ms. Chris Firestone January 19, 2011 Page 2 of 4

1. The LGS plant site, which hosts the two generating units, is located on Exelon Generation-owned properties that are mostly situated in Limerick Township.

Montgomery County, but some of which are in the adjacent Lower Pottsgrove Township, Montgomery County or directly across the Schuylkill River in East Coventry Township, Chester County.

2. The LGS makeup water supply system, which conveys water from approved sources to LGS for use in its circulating water system, is composed of the following components:

o The Perkiomen Pumphouse, located in Graterford Township, Montgomery County, and an associated underground 7.6-mile long Perkiomen Pumphouse-to LGS pipeline; both are located along an easement held by Exelon Generation within an electrical transmission line right-of-way (ROW) controlled by PECO, a subsidiary of Exelon Corporation; o The Bradshaw Reservoir and Bradshaw Pumphouse, which are both situated in Plumstead Township, Bucks County, on Exelon Generation-owned properties totaling 42 acres; o The Bedminster Water Processing Facility, which is situated in Bedminster Township, Bucks County, on a 3-acre Exelon Generation-owned property; and o An underground water transmission main, which is routed within a natural gas pipeline ROW along an easement held by Exelon Generation that runs from the Bradshaw Pumphouse to the East Branch Perkiomen Creek by way of the Bedminster Facility.

The buried Perkiomen Pumphouse-to-LGS water pipeline and the underground water transmission main are located below ground within ROWs that exist for other purposes, and their operation requires no independent vegetation management or ground disturbing activities along these ROWs. Hence, these underground components of the makeup water supply system are assumed to have no effects on threatened and endangered plant species.

3. The LGS transmission system is composed of the following components:

o Two electrical transmission lines constructed to connect the LGS main power transformers with two onsite electrical substations (these components are located on the LGS plant site); and o Four 230-kiioVolt (kV) and one 500-kV electrical transmission lines, with associated structures and offsite electrical substations, constructed to connect the onsite electrical substations to the regional electricity grid.

All offsite substations and transmission lines are operated by PECO and are located in ROWs situated in Montgomery and Chester Counties either on PECO-owned properties or on properties for which PECO holds pennits, grants, easements, or licenses. On site transmission lines traverse only land that was disturbed during initial station construction.

Figures 1 through 9 showing the locations of the existing LGS project features are provided in .

Ms. Chris Firestone January 19, 2011 Page 3 of 4 Activities During the License Renewal Terms LGS license renewal will involve no new construction, refurbishment, ground disturbing activities, changes to operations, or changes to existing land-use conditions. Operation and maintenance activities during the terms of the renewed LGS licenses are only expected to occur in previously disturbed areas or existing ROWs. Hence, no new adverse impacts to threatened and endangered plant species are anticipated from license renewal.

Identification of Threatened and Endangered Species Resources Using the Pennsylvania Natural Diversity Inventory (PNDI) Environmental Review Tool, a web based application sponsored by the Pennsylvania Natural Heritage Program (PNHP), Exelon Generation has reviewed the potential for the LGS plant site area and the properties associated with the LGS makeup water supply system to adversely affect known occurrences of species or natural communities of concern. Receipts for PNDI search #s 20100421240174 (LGS plant site), 20100421240163 (Perkiomen Pumphouse area), 20100406237563 (Bradshaw Reservoir and Pump house area), and 20100407237630 (Bedminster Water Processing Facility area) are attached (Attachment 1). One "Special Concern Species" was identified for the LGS plant site:

tooth-cup (Rotala ramosior). The responses for the other project sites stated that no impact is antiCipated to threatened and endangered species and/or special concern species or resources.

Given the sizable acreage and distances associated with the LGS transmission line corridors, no PNDI searches were conducted for this project component. For review by your office in identifying species of concern, we instead offer the figures in Attachment 3 showing the routes and widths of the corridors.

A review of the PNHP web site for state-listed endangered and threatened species indicates that numerous state-listed plant species could occur in Montgomery, Chester, and Bucks Counties. The enclosed Attachment 2 contains a list of these species. One perennial orchid species, the small whorled pogonia (lsotria mede%ides), state-listed as endangered, with Chester County as its recorded location, also is federally-listed as threatened. Although the American Holly (/lex opaca), which is state-listed as threatened, was observed on the LGS plant site in 1978, Exelon Generation is not aware of the recent presence of any state-listed plant species on or near the properties associated with LGS and its associated transmission lines.

Also, Exelon Generation and PEeO adhere to regulatory requirements regarding sensitive areas that could contain state-listed threatened and endangered plant species and work closely with your department to protect these resources.

Because license renewal involves no new construction, refurbishment, ground disturbing activities, changes to operation, or changes to existing land use conditions, Exelon Generation does not expect LGS license renewal to adversely affect threatened and endangered plant species located near the LGS plant site, makeup water supply system, or transmission system ROWs. Nevertheless, we are requesting your help to identify issues we may have overlooked that need to be addressed in the LGS license renewal environmental report. We are also interested in learning of any information your staff believes could help expedite the NRC's review of the LGS license renewal application. Hence, in closing, we would appreciate receiving a response from you detailing such issues and information for the LGS plant site, makeup water supply system and transmission system. We would also welcome your confirmation of our conclusion that LGS license renewal would not adversely affect threatened and endangered plant species.

Ms. Chris Firestone January 19, 2011 Page 4 of 4 Because we plan to incorporate a copy of your response, as well as this letter, into the LGS license renewal environmental report that will be submitted to the NRC as part of the LGS license renewal application, your response will be most helpful if we receive it by March 10, 2011.

Please call Nancy Ranek (610-765-5369), our License Renewal Environmental Lead, jf there are questions or you require additional information.

BUREAU OF FORESTRY March 9, 2011 PNDI Number: 21136 Michael P. Gallagher, PE Exelon Nuclear 200 Exelon Way KSA/2-E Kennett Square, PA 19348 Re: Renewal of Operating Licenses for Limerick Generating Station, Units 1 and 2 Chester, Montgomery, & Bucks Counties

Dear Mr. Gallagher,

Thank you for your submission of the Pennsylvania Natural Diversity Inventory (PNDI) Environmental Review Large Project Number 21136 for review. PA Department of Conservation and Natural Resources screened this project for potential impacts to species and resources of concern under DCNR's responsibility, which includes plants, terrestrial invertebrates, natural communities, and geologic features only.

No Impact Anticipated PNDI records indicate species or resources of concern are located in the vicinity of the project. However, since the renewal does not involve new construction, refurbishment, ground disturbance, changes to operations or existing land use conditions, DCNR has determined that no impact is likely to occur to species of special concern under our jurisdiction as a result of this project.

For your information, we have included details on the species of special concern which are known near the rights of way of the LGS transmission corridors. If plans change to include earth disturbance in these locations, please coordinate with us further.

Limerick to Cromby 230kV Transmission Line Route Rotolo romosior (Tooth-cup, PA Rare): habitat is described in Plants of PA, by Rhoads and Block as wet, sandy shores and other swampy open ground; flowers July-Sept. Tooth-cup is known in a wet wooded stretch along the west side of the Schuylkill River.

Cyperus schweinitzii (Schweintiz's fiatsedge, PA Rare): habitat includes dry or moist sand flats and dunes; flowering and fruiting time is mid-summer to early fall. Schweinitz's flatsedge was found in association with Tooth-cup in a wet wooded area along the west side ofthe Schuylkill River.

Arabis miss(iuriensis (Missouri rock-cress, PA Endangered): habitat includes dry slopes; flowers April early June. Missouri rock-cress was found nearby in a dry forested slope with scattered outcrops of Brunswick red shale. If work is planned (especially ROW widening) in the future for the eastern Limerick

-Cromby 220-60 Line, please coordinate with us further, Arabis patens (Spreading rock-cress, Currently Unlisted, Proposed PA Threatened): habitat is moist, rocky woods; flowers April-July. Spreading rock cress was found nearby in a shaded NW-facing rock face.

Cromby to North Wales 230kV Transmission Line Route Enclosure 7 conserve sustain enjoy p.o, Box 8552, Harrisburg, PA 17105-8552717-787-3444 (fax) 717-772-0271 dcnr.state,pa, us

PNDI Number: 21136 Arabis patens (Spreading rock-cress, Currently Unlisted, Proposed PA Threatened): habitat is moist, rocky woods; flowers April-July. Spreading rock cress was found nearby in a shaded NW -facing rock face.

Iris prismatica (Slender Blue Iris, PA Endangered): habitat is moist meadows and sandy or gravelly shores; flowering time is late May-June. Slender blue iris was found nearby in gently sloping land, open with scattered red maples in a mossy floodplain of the Perkiomen Creek.

Ranunculusfascicularis (Tufted buttercup, PA Endangered): habitat includes dry, think woods and exposed calcareious slopes and edges; flowers April-May. Tufted buttercup was found nearby in a ridgetop glade near trails in a state park.

Cromby to Plymouth Meeting 230kV Transmission Line Route Arabis patens (Spreading rock-cress, Currently Unlisted, Proposed P A Threatened): habitat is moist, rocky woods; flowers April-July. Spreading rock cress was found nearby in a shaded NW -facing rock face.

Andropogon gyrans (Elliott's beardgrass, Currently unlisted, Proposed P A Rare): habitat is dry or moist fields or open woods; flowering time is September to October. Elliott's beard grass was found nearby in an old field.

Cuscula campestris (Dodder, Currently Unlisted, Proposed PA Threatened): habitat includes thickets and waste ground, parasitic on wild and cultivated hosts; flowers June-September, fruits July-October. This dodder species was previously found in an old impounding basin, near the Schuylkill River.

Rotola romos;or (Tooth-cup, P A Rare): habitat includes wet, sandy shores and other swampy open ground; flowers July-Sept. This population of Tooth-cup was found on an exposed mud flat and sandy-cobbly shores of seasonally flooded shallow basins.

Limerick to Whitpain Meeting 500kV Transmission Line Route Ranunculus fasciculoris (Tufted buttercup, P A Endangered): habitat includes dry, think woods and exposed calcareious slopes and edges; flowers April-May. Tufted buttercup was found nearby in a ridgetop glade near trails in a state park.

Iris prismatica (Slender Blue Iris, PA Endangered): habitat is moist meadows and sandy or gravelly shores; flowering time is late May-June. Slender blue iris was found nearby in gently sloping land, open with scattered red maples in a mossy floodplain of the Perkiomen Creek.

This response represents the most up-to-date summary of the PNDI data flIes and is valid for oneQ..)xear from the date of this letter. An absence of recorded information does not necessarily imply actual conditions on-site. Should project plans change or additional infonnation on listed or proposed species become available, this detennination may be reconsidered. Should the proposed work continue beyond the period covered by this letter, please resubmit the project to this agency as an "Update" (including an updated PNDI receipt, project narrative and accurate map).

This finding applies to impacts to DCNR only. To complete your review of state and federally-listed threatened and endangered species and species of special concern, please be sure the U.S. Fish and Wildlife Service, PA Game Commission, and the Pennsylvania Fish and Boat Commission have been contacted regarding this project as directed by the online PNDI ER Tool found at www.naturalheri!:1!ge.state.pa.us.
