Worst case

The same rule on the worst case gives no rating above the point.

Scenario

OPSB requires the gross $11.6 million bond with no salvage credit, and the amount is contested through the OPSB process, with landowner security adding further burden.

Revision

First verdict
weakened
First critique

Core inputs, the salvage uncertainty and the worst case are well supported. However, the '60 days before construction' and 'engineer' details appear in no cited quote. The Carroll County agency listing is unsupported, and two uncited claims (C-4e2febbe42, C-640e804855) are not used. Category 3 holds.

Revised once after the first critique. Rating unchanged.

The five inputs

Comments

ORC 4906.21 to 4906.222 require a decommissioning plan and performance bond. Bond equal to the estimate is due before construction, updated every five years, never reduced. Estimate is $11.6 million gross, $5.7 million net of salvage; OPSB treatment of salvage is unsettled. Leases require 36-inch removal and separate landowner security.

Critique

Verdict
upheld
Suggested direction for the rating
same
Summary

Assessment is largely supported by the cited claims, and OPSB is the right agency. Two minor problems: the Parcel 7 easement removal term is not in the quote, and the landowner security is framed as additional when the bond is meant to satisfy it.

Issues

  1. Severity minor · Kind unsupported_statement

    The extent rationale cites C-4e2febbe42 for a Parcel 7 easement requiring removal of above-ground equipment two years after operations stop. The quote only says something 'ends two (2) years after it permanently stops operating'. It names no parcel and mentions no removal obligation. Extent 'core' still holds on the other claims.

    Cites C-4e2febbe42

  2. Severity minor · Kind overstatement

    The worst case says landowner security adds further burden, and the avoidable rationale lists separate security as an extra term. C-f3daa0fd5a says the bond is intended to satisfy the per-landowner security requirement, so it is likely duplicative rather than additional. The next step on aligning lease security with the bond is appropriate.
