Provenance should inform—not automatically determine—a material approval decision. The US EPA says recovered-content claims can be supported by estimates and certifications, while ASQ says a quality control plan may specify product tolerances, testing parameters, and acceptance criteria. These sources provide useful inputs, but they do not establish automatic approval or a universal documentation rule.
What Provenance Can—and Cannot—Decide
In this context, provenance means the documented basis for a recovered-material claim. A review should establish:
- Which material or component is being assessed.
- What recovered-material content is being claimed.
- Whether an estimate or certification supports that particular claim.
- Which tolerances, testing parameters, and acceptance criteria apply, if a quality control plan specifies them.
This is a practical review framework assembled from the cited statements, not a set of requirements prescribed by the US EPA or ASQ. Neither statement identifies a universally required certification, test, threshold, or approval outcome.
How to Check the Approval Basis
-
Define the claim precisely. Identify the material and the recovered content being claimed. A broad environmental description does not replace a specific material claim.
-
Match the evidence to that claim. The US EPA identifies estimates and certifications as possible support for recovered-content claims. The relevant documents should therefore be checked against the exact material and content claim rather than accepted merely because they use similar terminology.
-
Examine the acceptance conditions. If a quality control plan exists, look for product tolerances, testing parameters, and acceptance criteria. ASQ states that a plan may specify these items; it does not say that every plan must contain them.
-
Reconcile the three parts of the review. Compare the stated claim, its supporting evidence, and any applicable acceptance conditions. Any mismatch should remain an open issue rather than be treated as resolved by assumption.
-
Record the basis for approval. A decision record should distinguish evidence that has been checked from evidence that remains unverified. It should also identify who has authority to approve the material and what that authority requires in the relevant context.
What the Reader Must Still Confirm
The two cited statements do not settle several decision-specific questions:
- Whether estimates, certifications, or both are appropriate for the exact claim.
- Which certification, if any, is acceptable, and who is qualified to verify it within the relevant process.
- Whether a quality control plan applies and which tolerances, testing parameters, and acceptance criteria it contains.
- Whether the evidence remains applicable to the material and claim under review.
- Who has approval authority and how any unresolved evidence must be handled.
The cited statements also provide no required certification type, test method, threshold, deadline, fee, or guaranteed result. Those points cannot be inferred and must be confirmed for the particular project.
Provenance shapes the approval decision by making the basis of a recovered-material claim inspectable: the claim itself, evidence that can support it, and any acceptance criteria specified by the quality control plan. It does not replace the reader’s need to confirm that each element is valid and applicable to the material being approved.
