Pioneer Units 1 and 2 Site Redress Plan Construction Permit Application Part 1 Holtec International Copyrighted Material HI-2251680 Revision 2 1-1 1 Site Redress Plan This limited work authorization (LWA) application requests approval to perform construction activities for a dual-unit SMR-300 plant, with units individually named Pioneer 1 and Pioneer 2, at the Palisades Energy Center (PEC) Site in Covert, Michigan.
In accordance with 10 CFR 50.10(d)(3)(iii), an LWA application must include a plan for redress of activities performed under the LWA should limited work activities be terminated by the holder, the LWA be revoked by the U. S. Nuclear Regulatory Commission (NRC), or the Commission denies the associated construction permit (Part Two of the SMR-300 construction permit application).
10 CFR 50.10(g) requires that if construction is terminated, the holder must begin implementation of the redress plan in a reasonable timeframe and complete it within 18 months.
1.1 Purpose This site redress plan identifies and describes actions to mitigate or stabilize environmental impacts incurred during LWA activities. The purpose of the site redress plan is to ensure that if construction is terminated during or following LWA activities, the site is returned to an environmentally stable and aesthetically acceptable condition.
Redress will be completed in accordance with applicable land-use and or zoning requirements of local, state, and federal agencies. The scope of site redress will be proportionate with the extent of land modification resulting from LWA activities.
Two site redress options will be considered:
Establishment of preconstruction land contours and surface drainage features.
Potential completion or addition of site development features that enhance the value of the site for potential reuse.
Implementation of this plan will provide reasonable assurance that site redress will achieve an environmentally stable and aesthetically acceptable site.
1.2 Background
Enclosure I of this LWA application describes the construction activities that are planned under the LWA. It also provides general information concerning SMR, LLC (SMR), the applicant.
The preliminary safety analysis report (PSAR) included as Enclosure II describes the structures, systems, and components that will be installed under the LWA, including their locations on the PEC site. The Environmental Report (ER), included as Enclosure III of this LWA application, provides a detailed description of the site and describes the environmental impact of the planned activities, as well as plans to mitigate environmental impacts.
LWA activities will include installation of permanent excavation supports, soil improvement, and placement of backfill to support installation of foundations for the major structures. Concurrently, SMR is pursuing an exemption request to perform additional construction, including installation of the Steel-Concrete Containment Vessel and some internal structures of the Reactor Building and Reactor Auxiliary Building. Installation of buried duct banks and buried piping throughout the site is also planned.
Pioneer Units 1 and 2 Site Redress Plan Construction Permit Application Part 1 Holtec International Copyrighted Material HI-2251680 Revision 2 1-2 1.3 Discussion If redress is required, engineered plans and construction specifications will be developed before implementation. A schedule will also be developed.
1.3.1 Demolition and Grading Structures will be demolished below plant grade, consistent with typical decommissioning practices. Below-grade structures will be retired in place. Structures or features that enhance the value of the site for potential reuse may be retained.
Debris will be removed from the LWA area and properly disposed.
Site redress will include grading of the LWA area within the PEC Site and bounded by the project area to conform to the adjacent land surface, allow stormwater runoff, and prevent soil erosion. Backfill will be placed in accordance with good engineering practices and written specifications. Material from the original excavation will be used, if available. The disturbed LWA area will be revegetated to ensure surface stabilization and a visually-pleasing landscape.
1.3.2 Impacts During Redress Impact mitigation controls will ensure environmental protection and regulatory compliance during site redress. Controls will be consistent with the controls described in the ER for comparable activities.
During redress activities, ambient noise levels are expected to be similar to those during site preparation and LWA construction activities. The heavy equipment needed for demolition, clearing, excavating, grading, trash disposal, and land filling operations will be the potential source of noise pollution. Controls are expected to be consistent with those described in Section 4.4.1.5 and Section 4.11 of the ER. Noise will be controlled to maintain compliance with all local, state, and federal regulations.
The workforce necessary to perform redress is expected to be smaller than that necessary for LWA construction. Section 4.42 and Section 4.12.5.4 of the ER describe impacts associated with the workforce necessary for LWA activities.
Onsite and offsite traffic control will follow applicable local, state, and federal requirements, as well as existing PEC rules. Highway access to the project area is expected to experience traffic during redress activities at a level similar to that for LWA construction work. Workers will access the site via the construction access road. Section 4.4.1.3 of the ER describes traffic impacts associated with LWA activities.
A heavy haul road is planned to support LWA activities. The road is expected to have an interchange with Blue Star Highway in the northeast corner of the site. No other new access roads or road improvements are proposed. Equipment that exceeds highway weight and size limits will be transported to the site as heavy-haul, oversize cargo, or both. Heavy-haul and oversize loads are expected to utilize existing transportation infrastructure and their transport to the site will be planned and coordinated with state and local transportation departments as required.
Stormwater runoff from the site is expected to be collected in either catch basins or drainage swales dispersed around the facility. Once collected, the stormwater runoff will be conveyed through a combination of shared culverts and swales to a stormwater management system,
Pioneer Units 1 and 2 Site Redress Plan Construction Permit Application Part 1 Holtec International Copyrighted Material HI-2251680 Revision 2 1-3 consistent with the controls described in the ER. Section 4.2.3.1 and Section 4.11 of the ER describe planned stormwater management practices during LWA activities. As the stormwater is conveyed, it is expected to go through a series of treatments to improve the quality of discharge from the site. The system will be designed to meet the Michigan Department of Environment, Great Lakes, and Energy (EGLE) National Pollutant Discharge Elimination System discharge limits. Treatments will be based on the EGLE best management practices and may include bioretention cells, treatment swales, dry ponds, and various other techniques required to meet the county and state standards.
Dust, smoke, and engine exhaust are sources of air pollution. During redress activities, controls are expected to be imposed to mitigate air emissions from such sources, consistent with the controls employed during LWA activities. Controls will ensure compliance with applicable regulations and demonstrate that ambient air quality standards will not be threatened or exceeded by the facility's operation. Section 4.7.1 and Section 4.11 of the ER describe planned controls on air pollution during LWA activities.
Specific measures that are expected to be implemented to minimize and control fugitive dust include:
Stabilizing construction roads and unsuitable soils piles Limiting speeds on unpaved construction roads Using water for dust suppression Performing housekeeping Covering haul trucks when loaded or unloaded Minimizing material handling, such as limiting drop heights and double handling Ceasing grading and clearing activities during high winds Phasing grading to minimize the area of disturbed soils Revegetating road medians and slopes Emissions from construction activities and equipment will be unavoidable; however, programmatic measures can minimize impacts to local ambient air quality and the nuisance impacts to the public close to the project. The mitigation measures can include performing proper maintenance of construction vehicles to maximize efficiency.
During redress activities, there are expected to be different possible pollutant sources (e.g., effluents, wastes, spills, and material handling). Best management practices will be followed to ensure protection of soils, groundwater, and surface water from accidental spills or releases of pollutants. Any spills during redress activities will be remediated, consistent with the procedures implemented during LWA activities. Section 4.2.4.1, Section 4.2.4, Section 4.9.1, and Section 4.11 of the ER describe measures to address pollutants introduced during construction.
1.3.3 Responsibility and Reporting It is the financial responsibility of Holtec to provide funding to redress the LWA area on the project area in the event that limited work activities are terminated by the holder or the LWA is
Pioneer Units 1 and 2 Site Redress Plan Construction Permit Application Part 1 Holtec International Copyrighted Material HI-2251680 Revision 2 1-4 revoked by the NRC, or upon effectiveness of the Commissions final decision denying the associated construction permit or combined license application, as applicable.
SMR will provide a final report documenting that redress activities provide an environmentally stable condition and aesthetically acceptable site.
SMR will notify the NRC upon completion of site redress activities as described in this plan. The site will be made available for inspection by the NRC to confirm the satisfactory completion of the redress activities.
1.4 Summary This site redress plan is provided to meet the requirements of 10 CFR 50.10(d)(3)(iii). If required, redress activities will begin in a reasonable timeframe and be completed within 18 months, consistent with 10 CFR 50.10(g). During redress activities, controls are expected to be implemented, consistent with those used during LWA construction to minimize impacts. The impacts during redress will be less than or equal to those experienced during LWA activities.
Redress will be completed to return the site to an environmentally stable and aesthetically acceptable condition.
