What triggers the issuance of a Commissioner's Order (CO)?

The issuance of a Commissioner's Order (CO) is specifically triggered when a regulated entity fails to resolve an Agreed Order for violations. An Agreed Order is a negotiated resolution to violations where the entity commits to specific corrective actions. If they do not comply with the terms of that agreement or fail to reach a settlement in the first place, this creates a situation where the regulatory authority must step in to enforce corrective measures.

It's important to understand that the other options do not directly lead to a CO issuance. Compliance with state health standards indicates that an entity is functioning as required under existing regulations. Routine inspection results, while they may identify issues that need addressing, do not automatically lead to a CO unless there is a failure to comply. Public appeals for water quality checks highlight community concerns but also do not initiate a CO unless there's a corresponding failure to address violations following an Agreed Order. Thus, the correct answer reflects the specific circumstances under which a formal legal order is necessary due to a lack of compliance in settling violations.
