The assessor's comments

Nearest public-use airport (TSO) is about 5 miles southeast. Structures are over 20,000 feet from the runway and under 200 feet, so no FAA Form 7460-1 notice is required. Low-potential (green) glare predicted at two residences and a short segment of Linnet Road; no glare at TSO approaches.

Worst case

If what is pending at the cut-off went badly, the same rule gives a higher rating.

Scenario: Final layout or tilt changes raise glare at residences R-11 and R-14, requiring vegetative screening or module adjustments.
Step still pending: Updated glare analysis on the final layout
Inputs in the worst case: Extent peripheral · Avoidable yes · Pathway standard · Impact likely yes

2What the record shows

The five inputs

Present: yes
A public-use airport (TSO) is documented about 5 miles southeast (C-22ecd9258b), and low-potential green glare is predicted at two residences and a short segment of Linnet Road (C-1a3c29d782, C-3a488792dd). Contrary absence findings (no yellow/red glare, no TSO approach glare, no microwave path, no private airstrip, no military/radar) cover different receptors and are consistent with this (C-06d00931f7, C-7fb4ed5f9f, C-cf1066cd5b, C-47b8505413, C-4c304fc268).
Cites C-22ecd9258b, C-1a3c29d782, C-3a488792dd, C-06d00931f7, C-7fb4ed5f9f, C-cf1066cd5b, C-47b8505413, C-4c304fc268
Extent: peripheral
All structures are over 20,000 feet from the nearest runway, no protected surface is penetrated (C-698d47b3cd, C-7ae4ad619f), no microwave path crosses the area (C-cf1066cd5b). Only low-potential glare at a few receptors remains (C-1a3c29d782).
Cites C-698d47b3cd, C-7ae4ad619f, C-cf1066cd5b, C-1a3c29d782
Avoidable: yes
No yellow or red glare is predicted (C-06d00931f7); the green glare is minor and no airport surface is affected (C-7ae4ad619f). Layout, tilt or screening can address any residual issue.
Cites C-06d00931f7, C-7ae4ad619f
Pathway: none
No FAA Form 7460-1 notice is required, as structures are beyond 20,000 feet of the runway and under 200 feet (C-698d47b3cd). The ODOT Office of Aviation permit does not apply to an OPSB-certificated facility (C-8022ac270d, OH-AIRPORT). The glare study is already complete.
Cites C-698d47b3cd, C-8022ac270d
Impact likely: no
No glare at TSO approaches, no hazard to airspace, and only low-potential green glare at two residences and a short road segment of limited duration (C-7fb4ed5f9f, C-1a3c29d782, C-3a488792dd). A hazard determination or redesign is not likely.

3Permits and requirements

The requirements tied to the rows of this report, by level. Each quote from dated law is shown with its source, the version in force on the cut-off and the basis for it.

Federal (1)

Form 7460-1 Notice of Proposed Construction or Alteration
F-FAA77 · Federal Aviation Administration
Applicability
Conditional
Instrument
14 CFR Part 77
Trigger
Structures or cranes meeting notice criteria near airports or over 200 feet above ground.
Description
Notice for construction that meets Part 77 notice criteria (for example structures over 200 feet, or within defined distances and slopes of public-use airports). FAA's 2021 glare policy covers solar on federally obligated airports, not off-airport projects.
Typical timeline
Notice on Form 7460-1 at least 45 days before the start date of construction or the date a construction-permit application is filed, whichever is earliest (14 CFR 77.7(b)); Part 77 sets no FAA decision deadline. A Determination of No Hazard expires 18 months after its effective date unless extended (14 CFR 77.33(b)). Typical: 2 to 4 months for an FAA aeronautical study determination (basis: practice, not stated in the sources).
As of the cut-off
As of the cut-off: FAA published its interim policy on solar energy systems at federally obligated airports (78 FR 63276). (2013-10-23) FAA's policy on solar energy system projects at federally obligated airports took effect (86 FR 25801), replacing the 2013 interim policy; it covers on-airport systems at towered airports.

State (1)

ODOT Office of Aviation permit for a structure that may obstruct air navigation near an airport; not required for a facility holding an OPSB certificate, which is reviewed through the OPSB process
OH-AIRPORT · Ohio Department of Transportation (ODOT), Office of Aviation (permit); Ohio Power Siting Board (OPSB) (certificated facilities, after consulting the Office of Aviation)
Applicability
Conditional
Instrument
ORC 4561.30 to 4561.39 (Ohio Airport Protection Act); ORC 4561.341; ORC 4906.10(A)(5)
Trigger
A structure or object of natural growth that will penetrate, or is reasonably expected to penetrate, a protected surface of an airport open to the public, for a project that has not received an OPSB certificate.
Description
No person may begin to install a structure or object of natural growth, any part of which will or is reasonably expected to penetrate an airport's clear zone, horizontal, conical, primary, approach or transitional surface, without an ODOT permit. "Airport" means one certified for commercial purposes by ODOT; ODOT's guidance applies the permit to airports open to the public, and a filed FAA Form 7460-1 meets the state application requirement. ODOT grants or denies the permit by deciding whether the height and location would obstruct air navigation. A person who receives an OPSB certificate is not required to apply. Instead, if the Office of Aviation finds an obstruction, it gives the OPSB that determination in writing with either the conditions needed to remove it or a statement that compliance may be waived, and the OPSB must consult the Office.
Typical timeline
File not less than thirty days nor more than two years before the planned start of installation; the department may waive this period for unforeseen emergencies (ORC 4561.33(B)).
