Classifying MRR masses – step by step

MRR – Less Than Negligible Risk (Mindre än Ringa Risk) – determines whether excavated masses can be used without notification or permit. The concept is often confused with "clean masses" or soil guideline values. Download the guide for the framework, the responsibilities and how Sweden's new Chapter 15 of the Environmental Code changes the picture from 1 July 2026.

What's inside

  • What MRR actually is – and why it's not the same as "clean masses".
  • The three review levels and what they mean for notification or permit.
  • The four foundational questions to answer before classification.
  • Sampling, analysis and comparison against the Swedish EPA's Handbook 2010:1.
  • What the new Chapter 15 of the Environmental Code changes – and what it doesn't.
  • Checklist: before, during and after classification.
