City staff unveils proposed Nuclear Industrial Overlay zoning for K‑25, Horizon Center and Bear Creek areas
Loading...
Summary
Planning staff presented a draft 'Nuclear Industrial Overlay' (NIO) that would restrict long‑term storage, set hazard/security plan and financial‑assurance requirements, and apply initially to three western Oak Ridge industrial areas; council members pressed staff on time and quantity limits and whether IND‑2 is the proper base zoning.
Planning staff presented a draft Nuclear Industrial Overlay (NIO) at the March 17 work session, describing a text amendment and corresponding map changes intended to identify where nuclear‑regulated industrial uses may locate in Oak Ridge and to add site‑specific safeguards.
Miss Williams said the overlay is designed to layer onto the city’s IND‑2 industrial zoning and would use NAICS codes to identify regulated nuclear uses. The draft would require a site plan, security and hazard analyses, and financial assurances for new or redeveloped nuclear uses. “It will not preempt federal regulation of the nuclear industry,” she told council.
Staff proposed applying the overlay initially to three areas: the Heritage Center/ETTP (K‑25), a portion of the Horizon Center industrial park, and parts of the Bear Creek Road area including TVA property and nearby private parcels. The plan as presented excludes still‑federally owned (FIR) property; staff said if property is transferred to private ownership the usual rezoning process would apply.
Council members asked several technical and policy questions. Some members said they expect certain nuclear companies will require large buildings and heavy infrastructure and asked why the overlay was tied to IND‑2 rather than IND‑3 zoning. Miss Williams replied the overlay was intentionally framed to allow nuclear uses while eliminating other IND‑3 uses that have raised concern and that the overlay’s map can limit where it may be applied.
On long‑term storage, staff said the draft removed the word “waste” and instead uses a trigger based on whether there is a plan for future off‑site relocation: absence of a relocation plan distinguishes permanent storage from temporary process‑related storage. The draft does not currently include specific time limits (months/years) or fixed quantity thresholds; council members urged clearer guidance on timeframes, quantities, and distinctions between spent fuel, materials in process, and waste.
Staff said they have briefed existing nuclear businesses, mailed proposed text to property owners, and worked with the Oak Ridge Corridor Development Corporation; no businesses have formally opposed the draft, staff said. Miss Williams told council the item will return to the planning commission for consideration and then to council for any rezoning decisions.
Next steps: the planning commission will review the draft NIO language and map and return recommendations to city council; staff noted additional outreach and refinement may address council concerns about time/quantity definitions and appropriate base zoning.
