Introduction The NRC is considering issuance of amendments pursuant to § 50.54 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Conditions of licenses,’’ paragraph (q), to Renewed Facility Operating License No. DPR–49, held by NextEra Duane Arnold, LLC. (NextEra, the licensee) for the operation of Duane Arnold Energy Center (DAEC), located in Linn County, Iowa. In accordance with 10 CFR 51.21, the NRC has prepared an EA that analyzes the environmental effects of the proposed licensing action. Based on the results of the EA, and in accordance with 10 CFR 51.31(a), the NRC has prepared a finding of no significant impact (FONSI) for the proposed amendments. II. Environmental Assessment Description of the Proposed Action The proposed action would revise the DAEC Renewed Facility Operating License in order to set the DAEC Plume Exposure Pathway emergency planning zone (EPZ) boundary for an area beyond the 10-mile required EPZ pathway. The proposed action is in accordance with the licensee’s application dated March 31, 2017 (ADAMS Accession Nos. ML17102B183 and ML17102B184) and with current NRC’s regulations in 10 CFR 50.47, and 10 CFR part 50, appendix E. Notable proposed changes are (a) modification of Subarea 24 of the DAEC Plume Exposure Pathway EPZ by designating U.S. Highway 30 as its southern boundary, which will slightly decrease the total size of the EPZ, and (b) revision of the DAEC evacuation E:\FR\FM\05OCN1.SGM 05OCN1 46542 Federal Register / Vol. 82, No. 192 / Thursday, October 5, 2017 / Notices time estimate (ETE) study to account for the EPZ boundary changes. ethrower on DSK3G9T082PROD with NOTICES Need for the Proposed Action Nuclear power plant owners, government 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 helps decrease the consequences of an initiating event at a nuclear power reactor that proceeds 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 emergency plans to be implemented in the event of an accident. These emergency plans cover preparations for evacuation, sheltering, and other actions to protect residents near plants in the event of a serious incident. The NRC, as well as other Federal and state regulatory agencies review the subject plans to ensure that the condition of emergency preparedness 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 evaluating NextEra’s proposed changes to the EPZ boundary for DAEC. This review will be documented in the safety evaluation report for the proposed license amendment. The staff’s review will determine whether there is reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency in accordance with 10 CFR 50.47 and the requirements in appendix E to 10 CFR part 50. The proposed action is needed to make DAEC’s EPZ boundary more consistent with the existing roads and easier to implement more effectively. While changing the southern boundary to Highway 30 will decrease the size of the EPZ slightly, it will enhance local law enforcement’s ability to evacuate the affected population as well as improve their ability to control access back into the evacuated areas. The licensee states in its application (Adams Accession No. ML171028184) that the changes to the EPZ were approved by both the State of Iowa and the Federal Emergency Management Agency (FEMA). VerDate Sep<11>2014 19:52 Oct 04, 2017 Jkt 244001 Environmental Impacts of the Proposed Action The NRC has completed its evaluation of environmental effects of the proposed action. The proposed action consists of a modification to the DAEC EPZ boundary and revision to the DAEC ETE study to account for the EPZ boundary changes. Notable proposed changes are: (a) Modification of Subarea 24 of the DAEC Plume Exposure Pathway EPZ by designating U.S. Highway 30 as its southern boundary, which will slightly decrease the total size of the EPZ, and (b) revision of the DAEC ETE study to account for the EPZ boundary changes. The proposed changes would have no direct impacts on land use or water resources, including terrestrial and aquatic biota as the proposed action involves no new construction or modification of plant operational systems. There would be no changes to the quality or quantity of nonradiological effluents. No changes to the plant’s National Pollutant Discharge Elimination System permit are needed. Changes to the Southern boundary of the EPZ to Highway 30, a four-lane highway, could result in minor changes in vehicular traffic and associated air pollutant emissions, but no significant changes in ambient air quality would be expected. 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. Therefore, there would be no significant non-radiological impacts associated with the proposed action. The NRC has concluded that the proposed action would not significantly affect plant safety and would not have a significant adverse effect on the probability of an accident occurring. There would be no change to radioactive effluents that affect radiation exposures to plant workers and members of the public. No changes would be made to plant buildings or the site property. Changing the southern boundary of the EPZ to Highway 30 will slightly decrease the size of the EPZ; therefore, some residents that are located within the original EPZ boundary would no longer be subject to actions under the DAEC emergency plan. In the event of an accident, those residents not located in the EPZ could potentially receive a slightly higher radiation dose than those remaining within the modified EPZ, as they would no longer get mandated instructions from local law enforcement or other first responders pertaining to sheltering, evacuation, or other actions DAEC deems necessary to take under its PO 00000 Frm 00067 Fmt 4703 Sfmt 4703 emergency plan. However, as stated above, the NRC would only approve a reduction in the overall size of the DAEC EPZ if there is reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency in accordance with NRC’s regulations in 10 CFR part 50. As a result, the potential radiological dose increase to the residents located outside of the EPZ would not be significant, and in any event, residents located outside of the EPZ would be evaluated on an ad-hoc basis based on specific conditions. Therefore, the proposed action would not result in a significant change to the radiation exposures to the public or radiation exposure to plant workers. Accordingly, the NRC concludes that there would be no significant 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 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. Therefore, the environmental impacts of the proposed action and the denial of the exemption request would be similar. Alternative Use of Resources There are no unresolved conflicts concerning alternative uses of available resources under the proposed action. Agencies and Persons Consulted On September 8, 2017, the NRC staff consulted with the Iowa State official regarding the environmental impact of the proposed action. The state official had no comments. III. Finding of No Significant Impact The licensee has requested a license amendment pursuant to 10 CFR 50.54(q) to modify the DAEC Plume Exposure Pathway Emergency Planning Zone boundary. 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 non-radiological impacts. The reason the environment would not be significantly affected is because the proposed changes would only result in minor changes in associated vehicular traffic, along with resulting air pollutant emissions and would not result in a significant change E:\FR\FM\05OCN1.SGM 05OCN1 46543 Federal Register / Vol. 82, No. 192 / Thursday, October 5, 2017 / Notices to radiation exposures to the public or plant workers. 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.

SUPPLEMENTARY INFORMATION: 

I. Introduction

    The NRC is considering issuance of amendments pursuant to Sec.  
50.54 of title 10 of the Code of Federal Regulations (10 CFR), 
``Conditions of licenses,'' paragraph (q), to Renewed Facility 
Operating License No. DPR-49, held by NextEra Duane Arnold, LLC. 
(NextEra, the licensee) for the operation of Duane Arnold Energy Center 
(DAEC), located in Linn County, Iowa.
    In accordance with 10 CFR 51.21, the NRC has prepared an EA that 
analyzes the environmental effects of the proposed licensing action. 
Based on the results of the EA, and in accordance with 10 CFR 51.31(a), 
the NRC has prepared a finding of no significant impact (FONSI) for the 
proposed amendments.

II. Environmental Assessment

Description of the Proposed Action

    The proposed action would revise the DAEC Renewed Facility 
Operating License in order to set the DAEC Plume Exposure Pathway 
emergency planning zone (EPZ) boundary for an area beyond the 10-mile 
required EPZ pathway. The proposed action is in accordance with the 
licensee's application dated March 31, 2017 (ADAMS Accession Nos. 
ML17102B183 and ML17102B184) and with current NRC's regulations in 10 
CFR 50.47, and 10 CFR part 50, appendix E.
    Notable proposed changes are (a) modification of Subarea 24 of the 
DAEC Plume Exposure Pathway EPZ by designating U.S. Highway 30 as its 
southern boundary, which will slightly decrease the total size of the 
EPZ, and (b) revision of the DAEC evacuation

[[Page 46542]]

time estimate (ETE) study to account for the EPZ boundary changes.

Need for the Proposed Action

    Nuclear power plant owners, government 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 
helps decrease the consequences of an initiating event at a nuclear 
power reactor that proceeds 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 emergency plans to be 
implemented in the event of an accident. These emergency plans cover 
preparations for evacuation, sheltering, and other actions to protect 
residents near plants in the event of a serious incident.
    The NRC, as well as other Federal and state regulatory agencies 
review the subject plans to ensure that the condition of emergency 
preparedness 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 evaluating NextEra's 
proposed changes to the EPZ boundary for DAEC. This review will be 
documented in the safety evaluation report for the proposed license 
amendment. The staff's review will determine whether there is 
reasonable assurance that adequate protective measures can and will be 
taken in the event of a radiological emergency in accordance with 10 
CFR 50.47 and the requirements in appendix E to 10 CFR part 50.
    The proposed action is needed to make DAEC's EPZ boundary more 
consistent with the existing roads and easier to implement more 
effectively. While changing the southern boundary to Highway 30 will 
decrease the size of the EPZ slightly, it will enhance local law 
enforcement's ability to evacuate the affected population as well as 
improve their ability to control access back into the evacuated areas. 
The licensee states in its application (Adams Accession No. 
ML171028184) that the changes to the EPZ were approved by both the 
State of Iowa and the Federal Emergency Management Agency (FEMA).

Environmental Impacts of the Proposed Action

    The NRC has completed its evaluation of environmental effects of 
the proposed action. The proposed action consists of a modification to 
the DAEC EPZ boundary and revision to the DAEC ETE study to account for 
the EPZ boundary changes. Notable proposed changes are: (a) 
Modification of Subarea 24 of the DAEC Plume Exposure Pathway EPZ by 
designating U.S. Highway 30 as its southern boundary, which will 
slightly decrease the total size of the EPZ, and (b) revision of the 
DAEC ETE study to account for the EPZ boundary changes.
    The proposed changes would have no direct impacts on land use or 
water resources, including terrestrial and aquatic biota as the 
proposed action involves no new construction or modification of plant 
operational systems. There would be no changes to the quality or 
quantity of non-radiological effluents. No changes to the plant's 
National Pollutant Discharge Elimination System permit are needed. 
Changes to the Southern boundary of the EPZ to Highway 30, a four-lane 
highway, could result in minor changes in vehicular traffic and 
associated air pollutant emissions, but no significant changes in 
ambient air quality would be expected. 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. Therefore, there would be no significant non-radiological 
impacts associated with the proposed action.
    The NRC has concluded that the proposed action would not 
significantly affect plant safety and would not have a significant 
adverse effect on the probability of an accident occurring. There would 
be no change to radioactive effluents that affect radiation exposures 
to plant workers and members of the public. No changes would be made to 
plant buildings or the site property. Changing the southern boundary of 
the EPZ to Highway 30 will slightly decrease the size of the EPZ; 
therefore, some residents that are located within the original EPZ 
boundary would no longer be subject to actions under the DAEC emergency 
plan. In the event of an accident, those residents not located in the 
EPZ could potentially receive a slightly higher radiation dose than 
those remaining within the modified EPZ, as they would no longer get 
mandated instructions from local law enforcement or other first 
responders pertaining to sheltering, evacuation, or other actions DAEC 
deems necessary to take under its emergency plan. However, as stated 
above, the NRC would only approve a reduction in the overall size of 
the DAEC EPZ if there is reasonable assurance that adequate protective 
measures can and will be taken in the event of a radiological emergency 
in accordance with NRC's regulations in 10 CFR part 50. As a result, 
the potential radiological dose increase to the residents located 
outside of the EPZ would not be significant, and in any event, 
residents located outside of the EPZ would be evaluated on an ad-hoc 
basis based on specific conditions. Therefore, the proposed action 
would not result in a significant change to the radiation exposures to 
the public or radiation exposure to plant workers.
    Accordingly, the NRC concludes that there would be no significant 
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 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. Therefore, the environmental impacts of the 
proposed action and the denial of the exemption request would be 
similar.

Alternative Use of Resources

    There are no unresolved conflicts concerning alternative uses of 
available resources under the proposed action.

Agencies and Persons Consulted

    On September 8, 2017, the NRC staff consulted with the Iowa State 
official regarding the environmental impact of the proposed action. The 
state official had no comments.

III. Finding of No Significant Impact

    The licensee has requested a license amendment pursuant to 10 CFR 
50.54(q) to modify the DAEC Plume Exposure Pathway Emergency Planning 
Zone boundary. 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 non-
radiological impacts. The reason the environment would not be 
significantly affected is because the proposed changes would only 
result in minor changes in associated vehicular traffic, along with 
resulting air pollutant emissions and would not result in a significant 
change

[[Page 46543]]

to radiation exposures to the public or plant workers. 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.
    The related environmental document is the ``Generic Environmental 
Impact Statement for License Renewal of Nuclear Plants: Regarding Duane 
Arnold Energy Center, Final Report,'' NUREG-1437, Supplement 42. The
