Vegetative Management Plan Goals and Objectives:
Establish and sustain vegetation that will not require irrigation, regular fertilization, or pest management
Comply with all applicable regulatory requirements, including Linn County ordinances for ground cover, erosion and sediment control, stormwater management, and weed control Construction Phase
Cover Crops will be installed to:
o Maximize soil retention o
Aid in weed suppression o
Increase soil organic matter Operations Phase
Solar Panel Array Zone:
The solar panel array zone will consist of predominantly native perennial vegetation that would:
o Establish quickly o
Minimize erosion o
Manage runoff o
Build soil 20 Filed with the Iowa Utilities Board on November 23, 2021, GCU-2021-0002
Low growing perennial vegetation under panels will provide several benefits Solar facilities planted with locally appropriate low growing grasses could result in a 124% increase in pollinator supply, 22% increase in soil carbon storage, 90% increase in sediment capture, and 9% increase in storm water retention capacity (1)
The Projects are coordinating with Linn County to design a diverse seed mix that is expected to result in a further increase in benefits Allows land to remain fallow, promotes accumulation of organic material, and improves soil and water quality Inclusion of legumes will fix nitrogen into soils Minimal maintenance for vegetation in contrast to some tillage and agricultural practices that can weaken soils Typical maintenance includes mowing Limited herbicide spot-treatments for invasive or woody species as needed Land can return to agricultural use after decommissioning of the Project

Projects located on 100% voluntary easements At the conclusion of construction, the Project owner will meet with landowners to discuss and settle any confirmed construction damages.
Such confirmed construction damages may include crop compensation and repair to drainage tiles damaged as a result of Project construction.
Landowners are free to negotiate specific terms applicable to their property.
Conclusion of Construction 24 Filed with the Iowa Utilities Board on November 23, 2021, GCU-2021-0002
At the end of the Projects useful life, the Project owner will assess whether to cease operations and decommission the Project or to replace equipment and attempt to extend the life of the Project.
In general, decommissioning activities would include:
Dismantling and removal of all above ground equipment (solar panels, racking, transformers, Project Substation, BESS equipment, etc.);
Removal of all above ground cabling; Removal of posts; Break-up and removal of concrete pads and foundations; Pumping and break-up of any septic tank (backfilled with clean soil) and abandonment of leach field (if applicable);
Removal and/or abandonment of underground utilities; and Scarification of compacted areas within and contiguous to the solar plant facility (including but not limited to internal and external access roadways).
For the Gen-Tie line and collector substation, dismantling would include:
Dismantling and demolishing above ground structures; Removal of concrete foundations; Excavation and removal of soils and broken concrete from the site; and Surface contouring to return the disturbed areas to near-original conditions.

Questions?
28 Filed with the Iowa Utilities Board on November 23, 2021, GCU-2021-0002
December 20, 2021 Thank you for the opportunity to provide comment on the Post Shutdown Decomission Activities Report submitted by NextEra Energy on April 2, 2020.
There are three areas that appear to be worthy of consideration by the Nuclear Regulatory Commission in light of the proposed Utility Solar development by NextEra Energy which will border Duane Arnold Energy Center (DAEC).
Tritium Under section 2.3.6 Groundwater Protection and Radiological Decommissioning Records Program it is noted In 2012, measureable amounts of tritium began to be detected in some of the groundwater monitoring wells in an area immediately adjacent to the south side of the Turbine and Reactor buildings, continuiing for a short distance to the southeast on the plant property.
The document then goes on to state, As a result of the ongoing mitigation and given a tritium half-life of 12.3 years, no tritium mitigation is expected to be required at the end of the SAFSTOR period.
The questions we would like nuclear regulators to consider.
1.) Will the driving of beams repeatidly in the soil cause disruption of underground water which could cause the previously controlled tritium plume to disperse?
2.) Will the distruption and/or damage of field drainage tile sytems near DAEC due to construction of Duane Arnold Solar (DAS) disrupt groundwater and change the containment of the tritium?
Fire Management In 2.2.1.4 Fire Protection Systems indicates the ability to protect spent fuel and other radioactive materials from potential fire induced releases.
The outstanding question we would like the Nuclear Regulatory Commission to verify is the facility ready to handle potential fire risk from a nearby utlity solar and battery installation with volunteer fire department support?
Security requirement discussed in 2.2.2 Dormancy is Security during the dormancy period will be conducted primarily to safeguard spent fuel on site and prevent unauthorized entry. The key words we observed in this paragraph are unauthorized entry.
There appears there may be two different security challenges due to construction of the Utility Solar facility.
1.) the increased amount of traffic that will be within proximity to the facilty during the period of construction and 2.) the reduced visibilty upon conclusion of the construction due to rows of solar panels that will project approximately 13 into the air at maximum height.
Will these changes need to impact operational plans during the decommisssioning period?
Fund Segregation Finally, in the letter dated February 20, 2020 regarding the Request for Exemptions from 10 CFR 50.82(a)(8)(i)(A) and 10 CFR 50. 75(h)(1 )(iv) submitted by Dean Curtland of NextEra Energy Duane Arnold Energy LLC indicated Section (a)(S)(i)(A) of 10 CFR 50.82, "Termination of license," states the following:
Decommissioning trust funds may be used by licensees if -- (A) The withdrawals are for expenses for legitimate decommissioning activities consistent with the definition of decommissioning in § 50. 2.
Would the regulator make sure that if any issues occur at DAEC due to construction or operation from Duane Arnold Solar facilities, that those items are not paid from the DAEC decommissioning trust funds?
Included with this document is the presentation NextEra Energy submitted to the Iowa Utilites Board on November 23, 2021 to provide size, scope and placement of the project.
Again, thank you for the opportunity to provide comment and raise questions.
Sincerely, Bari Richter 915 Duroe St.
