Reading monitoring data findings on a CAR
Monitoring conditions — stack tests, effluent sampling, MCERTS continuous monitors, annual returns — produce the data Environment Agency officers compare to permit limits during a Compliance Assessment Report (CAR) visit. This guide helps you read monitoring-related non-compliances as printed on the form. Source: published EA assessing and scoring guidance (OGL v3.0).

Where monitoring findings sit on the CAR
Monitoring breaches usually appear under assessed areas such as emissions to air, discharges to water, or reporting / management systems. Each row includes:
- Permit condition reference — link to your PDF via linking CAR findings to permit conditions.
- Description — exceedance, missing data, flawed methodology, late reporting.
- Risk category and points under the Compliance Classification Scheme.
- Actions required and deadline — see CAR response deadlines.
Exceedance vs missing records
Officers may record two related but distinct issues:
| On the CAR | Plain-English reading |
|---|---|
| Limit exceedance with data attached | A sample or monitor reading breached a numeric permit limit. |
| Monitoring not undertaken / records not available | Compliance cannot be demonstrated — may score even without a numeric exceedance. |
| MCERTS / calibration issues | Data reliability challenge — methodology breach. |
| Late annual return | Reporting breach — may sit under management systems. |
Foreseeable impact scoring
Unlike amenity conditions (odour, noise — see odour, dust and noise findings), most monitoring breaches use reasonably foreseeable impact if unresolved. A minor exceedance may print as C3 at 4 points; sustained or serious breaches may reach C2 at 31 points. CARBrief quotes categories exactly as printed.
Link back to the permit schedule
Monitoring limits live in permit schedules — frequency, methods, alert thresholds. Use how to read an environmental permit to find the cited condition table. Improvement conditions may add extra monitoring deadlines — see improvement conditions.
Evidence operators typically hold
CARBrief does not audit your files — but after a monitoring finding, operators often review:
- Raw data and lab certificates for the inspection period.
- MCERTS calibration and maintenance logs.
- Submitted returns vs permit reporting frequency.
- Corrective actions already taken before the CAR arrived.

Questions
How are monitoring breaches scored on a CAR?
Most permit monitoring breaches use reasonably foreseeable impact scoring unless the condition is in the amenity group. The category and points printed on the CAR are what CARBrief extracts — we do not re-score.
What if monitoring records were missing during the inspection?
Missing records may be recorded as a reporting or management breach separate from an exceedance. Read each non-compliance row and the cited permit condition.
Does CARBrief validate MCERTS calibration?
No. CARBrief reads what the EA recorded on the published CAR. You hold monitoring QA evidence and lab certificates.
