1.0 INTRODUCTION

By application dated December 17, 2004, Exelon Generation Company, LLC (EGC) and AmerGen Energy Company, LLC (AmerGen), the licensees, requested changes to Appendix B, Environmental Protection Plan (EPP), for Braidwood Station, Units 1 and 2; Byron Station, Units 1 and 2; Clinton Power Station, Unit 1; LaSalle County Station, Units 1 and 2; Limerick Generating Station, Units 1 and 2; Oyster Creek Nuclear Generating Station; Peach Bottom Atomic Power Station, Units 2 and 3; and Quad Cities Nuclear Power Station, Units 1 and 2.

This amendment addresses the licensees proposed changes for Limerick Generating Station, Units 1 and 2 (Limerick). Other amendments will be or were issued to address the proposed changes for the other operating units.

The proposed changes revise the EPP for Limerick, Units 1 and 2, by clarifying a number of items without changing the purpose, by removing the requirement for an annual report, by updating terminology, by deleting obsolete program information, and by standardizing wording in the EPP.

2.0 REGULATORY EVALUATION

The EPP was established during initial plant operation to monitor environmental issues such as potential erosion along the transmission lines and the cooling tower drift impact on vegetation, noise, and cultural resources issues. The regulatory basis for the establishment of the EPP is Section 50.36b of Title 10 of the Code of Federal Regulations (10 CFR), ?Environmental Conditions. This section authorizes the Nuclear Regulatory Commission (NRC or the Commission) staff to place conditions on a license to protect the environment. The regulation states that the conditions will identify the ?obligations of the licensees in the environmental area, including, as appropriate, requirements for reporting and keeping records of environmental data, and any conditions and monitoring requirement for the protection of the nonaquatic environment and that the conditions will be derived from the licensees environmental report and the NRCs evaluation in the record of decision. However, in the March 12, 1984, statements of consideration for the final rule that created 10 CFR 50.36b, the Commission stated that the NRC ?may also include additional environmental conditions as appropriate.

3.0 TECHNICAL EVALUATION

Cover Page and Table of Contents Requested Action Reference to the alternate unit has been removed from the title on the cover page and table of contents. This administrative change is incorporated for clarity. The documents are part of unit-specific Technical Specifications and should be labeled as such.

NRC Staff Analysis This change is administrative and has no impact on safety. The change is acceptable.

Section 1.0 Objectives of the Environmental Protection Plan Requested Action A change is proposed to remove references to facility construction from Section 1.0. This section contains the objectives of the EPP, which are to provide for protection of the environmental values during operation of the nuclear facility. Construction is complete at Limerick and, therefore, the reference to environmental effects of facility construction is deleted from sub-section (3).

NRC Staff Analysis The facility construction references were included to cover the impacts related to the latter stages of the construction of the plants. The associated activities were completed many years ago; therefore, the staff concludes that removal of these references is administrative and has no impact on safety. This administrative change is acceptable.

Section 3.1 Plant Design and Operation Requested Action The proposed change in Section 3.1, ?Plant Design and Operation, is to delete the reference to the Annual Environmental Operating Report. With the deletion of the Annual Environmental Operating Report in Section 5.4.1, a reference within this section is not required.

NRC Staff Analysis The staffs analysis and conclusion regarding the need for the annual report is discussed in the evaluation for Subsection 5.4.1. Without the annual report, the NRC staff will not receive summaries of the evaluations of changes by the licensees. However, these evaluations will be available for staff review at the plant. In addition, Section 3.1 will still require the licensees to obtain NRC staff approval for any changes that involve an unreviewed environmental question.

Therefore, the staff concludes that the removal of the requirement for annual reporting of the licensees evaluations for unreviewed environmental questions is acceptable.

Section 3.2 Reporting Related to the NPDES [National Pollutant Discharge Elimination System] Permit and State Certification Requested Action The proposed changes in Section 3.2 are to revise the reporting requirements related to approval or changes to the NPDES permit or State certification.

Currently, this section requires that changes and additions to the NPDES permit or the State certification shall be reported to the NRC. This section also requires that a proposed revision be sent to the NRC at the same time as it is submitted to the permitting agency. However, the NRC relies on the State regulatory agency to regulate these matters; therefore, proposed changes will no longer be provided to the NRC. Changes to the NPDES permit or State certification will continue to be provided to the NRC within 30 days of approval. Information related to environmental permits will continue to be available onsite for NRC review.

NRC Staff Analysis The EPPs require the licensees to provide the NRC staff with copies of proposed revisions to, or renewals of, the NPDES permits. However, the NRC staff does not have a role in determining the NPDES limits for the plants. This responsibility lies with the appropriate NPDES permitting authority. Therefore, requiring the licensees to submit proposed NPDES permit changes is of little value to the NRC staff. The paragraph that will remain in the EPP will still require the licensees to provide the staff with copies of the approved revised permits. This requirement will allow the NRC staff to remain cognizant of those environmental impacts of plant operations related to the permits. In addition, the EPPs will continue to require the licensees to evaluate plant changes for unreviewed environmental questions. This requirement ensures that significant changes to the environmental impacts of plant operation will receive an NRC staff review that is independent of the NPDES review by the permitting authority. While the NRC staff will have no role in setting the limits in the NPDES permits, the staff will consider other impacts (e.g., to threatened and endangered aquatic species) that may not be included in the NPDES review. Based on this information, the staff concludes that the proposed changes are acceptable.

Section 3.3 Changes Required for Compliance with Other Environmental Regulations Requested Action A change is proposed to replace the phrase ?required to achieve compliance with other with the phrase ?that are either regulated or mandated by. This section exempts those changes that are regulated or mandated by other Federal, State, and local environmental regulations from the requirements of Section 3.1. An additional sentence has been added to state,

?However, if any environmental impacts of a change are not evaluated under other Federal, State or local environmental regulations, then those impacts are subject to the requirements of Section 3.1. This is an administrative change to improve clarity and understanding and does not change the objective of the original statement.

NRC Staff Analysis The current Section 3.3 applies the exemption from Section 3.1 only to those changes, tests, or experiments that are required to achieve compliance with the regulations of various agencies.

The revision expands this exemption to include environmental impacts that are evaluated by these various agencies. This change has the effect of focusing Section 3.1 on those environmental impacts that will not otherwise receive a review by a cognizant Federal, State, or local agency. Impacts that are the subject of the expansion of the exemption will still be evaluated, but by the appropriate cognizant agency. Therefore, the NRC staff concludes that this change is acceptable.

Section 4.1 Unusual or Important Environmental Events Requested Action A change is proposed that if an event is reportable under 10 CFR 50.72, immediate notification requirements for operating nuclear power reactors, then a duplicate immediate report in accordance with the stations EPP is not required. Requirements are provided in the EPPs to report unusual or important environmental events to the NRC within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Unusual and important environmental events are defined as any occurrence of an event that indicates or could result in significant environmental impact causally related to plant operation. Such events shall be recorded and reported to the NRC within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and followed by a written report.

Similarly, 10 CFR 50.72(b)(2)(xi) states that the licensee shall notify the NRC as soon as practical and in all cases, within four hours of the occurrence of...?any event or situation, related to the health and safety of the public or onsite personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. The change proposed will relieve the administrative burden of making duplicate reports to the NRC for the same event. Follow-up written reports are still required to be submitted in accordance with the EPPs.

NRC Staff Analysis The change is a clarification to avoid potential duplicate reporting requirements. At the time the EPPs were developed, there was no environmental reporting requirements in 10 CFR 50.72.

Thus, there was no issue with the potential for duplicate reporting. Based on this information, the NRC staff finds the proposed changes acceptable.

Section 4.2.3 Maintenance of Transmission Line Corridors Requested Action A change is proposed to Section 4.2.3 to delete the records retention requirements for use of herbicides within the Limerick transmission line corridors. The use of herbicides (and pesticides) in the transmission line corridors shall be conducted in accordance with 40 CFR 171.7, ?Submission and approval of State plans for certification of commercial and private applicators of restricted use pesticides and Title 7, Section 128 of the Pennsylvania Code. The records related to the use of herbicides within the Limerick transmission line corridors are required to be maintained by the herbicide/pesticide ?application business in accordance with Title 7, Section 128 of the Pennsylvania Code. Section 128.35 requires the applicator to maintain records relating to type and use for a record-retention period of 3 years.

The record retention period is effectively changed from 5 years to 3 years and is consistent with Title 7, Section 128.35 of the Pennsylvania Code. The licensees will still maintain overall responsibility for use and application of herbicides in the transmission corridors by vendors.

NRC Staff Analysis The record-retention period is effectively changed from 5 years to 3 years and is consistent with Title 7, Section 128.35 of the Pennsylvania Code. The licensees will still maintain overall responsibility for use and application of herbicides in the transmission corridors by vendors.

The NRC staff concludes that these changes are acceptable.

Section 4.2.4 Noise Monitoring Requested Action A change is proposed to Section 4.2.4 to delete the historical requirements for sound surveys and insert a statement that all noise-monitoring programs identified in Section 2.3 have been completed and no further monitoring under these programs is required.

The general sound level surveys were performed and the program was terminated upon completion. The following reports listed contain detailed information which demonstrate the noise levels emanating from Point Pleasant Pumping Station, Bradshaw Reservoir, and Limerick met all applicable noise-related regulations. The surveys were documented as follows.

1.

Limerick Generating Station Environmental Noise Assessment Final Report (February 1991)

2.

Point Pleasant Pumping Facilities Operational Environmental Noise Assessment Report (December 1989)

3.

Bradshaw Reservoir Pumping Facilities Environmental Noise Assessment Final Report (March 1991).

With all noise issues raised by the NRC in the Final Environmental Statement for the Limerick Operating License (FES-OL) addressed, Section 4.2.4 may be deleted in its entirety.

NRC Staff Analysis The confirmatory sound level survey requirements were completed for the Limerick in 1989 and 1991. No further monitoring under these programs is required. The NRC staff concludes that these changes are acceptable.

Section 5.2 Records Retention Requested Action A revision is proposed to change the requirement of log and data retention and retention timeframe from the ?life of the station to ?until the date of termination of the operating license.

The justification presented in Section 4.1 of this license amendment request (LAR) is applicable to Limerick. This section requires retention of records relative to the environmental aspects of plant operation and modifications determined to potentially affect the continued protection of the environment. An administrative requirement to maintain logs is deleted. The requirement to maintain all records is maintained. There are no dedicated environmental logs maintained on site. Logs relative to the environment are required to be documented by specific State permits (i.e., NPDES permit) and EGC environmental administrative procedures. Such entries are maintained as part of station operating logs. The reference to environmental logs has been deleted for clarity but the purpose of the original statement is maintained.

The proposed change in the retention timeframe to the termination of the operating license makes the requirement consistent with similar requirements in other regulations (i.e., 10 CFR 50.59). This change has been proposed to provide clarity, but does not change the objective of the requirement.

NRC Staff Analysis The proposed change regarding the types of records retained simplifies the EPPs by requiring the retention of records associated with the EPPs. The existing reference to data and logs refers to information that would have been collected under the now-completed monitoring programs. The change to the stated retention period makes the requirement consistent with other similar requirements in the NRC regulations (e.g., 10 CFR 50.59, ?Changes, tests, and experiments). The NRC staff concludes that these changes are acceptable.

Section 5.4.1 Routine Reports Requested Action A change is proposed to delete the entire section relating to routine reports. The justification presented in Section 4.1 of this LAR is applicable to Limerick. Further justification specific to Limerick is discussed below.

This section requires that an annual environmental operating report be submitted to the NRC by May 1st of each year. The report includes a list of EPP noncompliances and the corrective actions taken to remedy them; a list of all changes in the station design or operation, tests, and experiments made in accordance with Section 3.1 involving potentially-significant unreviewed environmental questions; and a list of nonroutine reports submitted in accordance with Subsection 5.4.2 of the EPP.

As previously discussed in Section 4.2 of the EPP, ?Environmental Monitoring, no specific environmental monitoring is required. Environmental non-compliances are reported as required by 10 CFR 50.72, ?Immediate notification requirements for operating nuclear power reactors, or 10 CFR 72.75, ?Reporting requirements for specific events and conditions. Section 10 CFR 50.72(b)(2)(xi) states that the licensee shall notify the NRC as soon as practical and in all cases, within four hours of the occurrence of...?any event or situation, related to the health and safety of the public or onsite personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made.

Section 10 CFR 72.75(b)(2) states each licensee shall notify the NRC for ?any event or situation related to the health and safety of the public or onsite personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Significant EPP non-compliances and appropriate non-routine reports will be communicated to the NRC under these regulations. Corrective actions for environmental noncompliances are tracked through the stations Corrective Action Program and completed corrective actions are available to the NRC for review. Changes in the station design or operation, tests, and experiments involving potentially-significant unreviewed environmental questions are addressed by the EGC and AmerGen implementing procedures associated with 10 CFR 50.59. For activities that involve a change to the Environmental Protection Program, the 10 CFR 50.59 Applicability Review Form and the Exelon 50.59 Resource Manual refer to EGC Environmental Evaluation procedures. When the environmental evaluation indicates that such an activity involves an unreviewed environmental question, a written evaluation is required to be submitted to the NRC, and approval must be obtained prior to implementation. When such an activity involves a change to the EPP, a license amendment shall be submitted to the NRC in accordance with 10 CFR 50.90.

All the requirements for the annual report are addressed in 10 CFR 50.72,10 CFR 72.75, the EGC 10 CFR 50.59 Review Program, Environmental Evaluation Program, or are no longer required. Therefore, Section 5.4.1 may be deleted in its entirety.

NRC Staff Analysis Monitoring programs are either done, or are monitored by the cognizant State agency. Based on the existing requirements in NRC regulations, the NRC staff concludes that the annual report is not necessary and this requirement can be deleted.

Section 5.4.2 Nonroutine Reports Requested Action A change is proposed to Section 5.4.2 to revise a ?nonroutine event to be an ?unusual or important environmental event.

Currently, this section requires written reports to be sent to the NRC within 30 days of occurrence of a nonroutine event. An administrative change is being made to clarify the objective of the section to refer to an ?unusual or important environmental event as described in Section 4.1 of Appendix B. This change is also for consistency with all other EGC and AmerGen stations.

NRC Staff Analysis The NRC staff has reviewed the EPPs and concludes that the intent of Subsection 5.4.2 was to require a written report for the events described in Subsection 4.1. Therefore, the staff concludes that the proposed clarification is acceptable.

4.0 STATE CONSULTATION

In accordance with the Commissions regulations, the Pennsylvania State official was notified of the proposed issuance of the amendments. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change requirements with respect to record keeping, reporting, or administrative procedures or requirements with respect to the EPPs. Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration and there has been no public comment on such finding (70 FR 19115).

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
