SUPPLEMENTARY INFORMATION:
I. Introduction The NRC is considering issuance of amendments to the following licenses held by Exelon: (1) Renewed Facility Operating License Nos. NPF-72 and NPF-77 for the operation of Braidwood, Unit Nos. 1 and 2, respectively, located in Will County, Illinois; (2) Renewed Facility Operating License Nos.

DPR-29 and DPR-30 for the operation of Quad Cities, Unit Nos. 1 and 2, located in Rock Island County, Illinois.
In accordance with section 51.21 of title 10 of the Code of Federal Regulations (10 CFR), the NRC performed the following EA that analyzes the environmental impacts of the proposed licensing action. Based on the results of this EA, and in accordance with 10 CFR 51.31(a), the NRC has determined not to prepare an environmental impact statement for the proposed licensing action, and is issuing a FONSI.
II. Environmental Assessment Description of the Proposed Action The proposed action would revise the ERO positions identified in the emergency plan for each facility. The on-shift, minimum, and full-augmentation ERO staffing requirements listed in the emergency plan would be revised. The proposed revisions include eliminating ERO positions; adding ERO positions; changing position descriptions, duties, and duty locations; and relocating certain position descriptions to other parts of the emergency plan or to implementing procedures.
The proposed action is in accordance with the licensees application dated January 31, 2018 (ADAMS Package Accession No. ML18053A159).
Need for the Proposed Action Nuclear power plant owners, Federal agencies, and State and local officials work together to create a system for emergency preparedness and response that will serve the public in the unlikely event of an emergency. An effective emergency preparedness program decreases the likelihood of an initiating event at a nuclear power reactor 4
proceeding to a severe accident. Emergency preparedness cannot affect the probability of the initiating event, but a high level of emergency preparedness increases the probability of accident mitigation if the initiating event proceeds beyond the need for initial operator actions.
Each licensee is required to establish an emergency plan to be implemented in the event of an accident. The emergency plan, in part, covers preparation for evacuation, sheltering, and other actions to protect individuals near plants in the event of an accident.
The NRC, as well as other Federal and State regulatory agencies, reviews the emergency plan to ensure that it provides reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.
Separate from this EA, the NRC staff is performing a safety assessment of Exelons proposed changes to the emergency plan for each facility. This safety review will be documented in a safety evaluation. The safety evaluation will determine whether, with the proposed changes to the emergency plan for each facility, there continues to be reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency at Braidwood, Byron, Clinton, Dresden, LaSalle, or Quad Cities, in accordance with the standards of 10 CFR 50.47(b) and the requirements in appendix E to 10 CFR part 50.
The proposed action is needed to align the emergency plans for Exelons facilities with draft Revision 2 to NUREG-0654/FEMA-REP-1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants (ADAMS Accession Nos. ML14163A605 and ML17083A815). This change will provide Exelon with greater flexibility in staffing ERO positions, and reflects changes in NRC regulations and guidance and advances in 5
technologies and best practices that have occurred since NUREG-0654 was originally issued in 1980. The State of Illinois reviewed a draft of the licensees application and recommended its approval. The State of Iowa reviewed a draft of the license amendment request for Quad Cities, and had no comments or concerns.
Environmental Impacts of the Proposed Action The NRC staff has completed its evaluation of the environmental impacts of the proposed action.
The proposed action consists mainly of changes related to the staffing levels and positions specified in the emergency plans for Braidwood, Byron, Clinton, Dresden, LaSalle, and Quad Cities. The on-shift, minimum, and full-augmentation ERO staffing requirements listed in the emergency plan would be revised. The revisions include eliminating ERO positions; adding ERO positions; changing position descriptions, duties, and duty locations; and relocating certain position descriptions to other parts of the emergency plan or to implementing procedures.
With regard to potential nonradiological environmental impacts, the proposed changes would have no direct impacts on land use or water resources, including terrestrial and aquatic biota, as they involve no new construction or modification of plant operational systems. There would be no changes to the quality or quantity of nonradiological effluents and no changes to the plants National Pollutant Discharge Elimination System permit are needed. Changes in staffing levels could result in minor changes in vehicular traffic and associated air pollutant emissions, but no significant changes in ambient air quality would be expected from the proposed changes. In addition, there would be no noticeable effect on socioeconomic conditions in the region, no environment justice impacts, and no impacts to historic and cultural resources from 6
the proposed changes. Therefore, there are no significant nonradiological environmental impacts associated with the proposed action.
With regard to potential radiological environmental impacts, if the NRC staffs safety review of the proposed changes to the licensees emergency plans determines that, with the proposed changes, the emergency plans continue to meet the standards of 10 CFR 50.47(b) and the requirements in appendix E to 10 CFR part 50, then the proposed action would not increase the probability or consequences of radiological accidents. Additionally, the NRC staff has concluded that the proposed changes would have no direct radiological environmental impacts. There would be no change to the types or amounts of radioactive effluents that may be released and, therefore, no change in occupational or public radiation exposure from the proposed changes.
Moreover, no changes would be made to plant buildings or the site property from the proposed changes. Therefore, there are no significant radiological environmental impacts associated with the proposed action.
Environmental Impacts of the Alternatives to the Proposed Action As an alternative to the proposed action, the NRC staff considered denial of the proposed action (i.e., the no-action alternative). Denial of the license amendment request would result in no change in current environmental impacts. Accordingly, the environmental impacts of the proposed action and the no-action alternative are similar.
Alternative Use of Resources There are no unresolved conflicts concerning alternative uses of available resources under the proposed action.
7
Agencies and Persons Consulted No additional agencies or persons were consulted regarding the environmental impact of the proposed action.
III. Finding of No Significant Impact The licensee has requested license amendments pursuant to 10 CFR 50.54(q) to revise the ERO positions identified in the emergency plans for Braidwood, Byron, Clinton, Dresden, LaSalle, and Quad Cities by eliminating ERO positions; adding ERO positions; changing position descriptions, duties, and duty locations; and relocating certain position descriptions to other parts of the emergency plan or to implementing procedures. The NRC is considering issuing the requested amendments. The proposed action would not significantly affect plant safety, would not have a significant adverse effect on the probability of an accident occurring, and would not have any significant radiological and nonradiological impacts. The reason the environment would not be significantly affected is because the proposed changes would only result in minor changes in staffing levels and a small change in in air pollutant emissions associated with vehicular traffic. This FONSI incorporates by reference the EA in Section II of this notice. Therefore, the NRC concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the NRC has determined not to prepare an environmental impact statement for the proposed action.
