DMR quality guide
A DMR is a period-bound evidence package
A valid-looking value is unsafe when it belongs to the wrong period, parameter, unit, monitoring location or permit limit.
Period control
Bind every result to the permit-defined reporting period and due date.
Parameter control
Preserve parameter, monitoring location, unit, frequency and limit mappings.
Missing data
NODI decisions require customer facts and permit context. Software should surface the decision, not invent it.
Operational boundary: This guide explains a controlled workflow. Contract terms, permits, portal instructions and official decisions remain authoritative.
