1. The operator of an installation applying for free allocation pursuant to Article 4 or 5 must, except where a monitoring methodology plan has already been approved in relation to the installation under this Article, draw up a monitoring methodology plan containing, in particular, a description of the production processes and a detailed description of monitoring methodologies and data sources. The monitoring methodology plan shall comprise a detailed, complete and transparent documentation of all relevant data collection steps, and shall contain at least the elements laid down in Annex VI.

2. For each parameter listed in Annex IV, the operator shall select a monitoring method based on the principles laid down in Article 7 and on the methodological requirements laid down in Annex VII. Based on the risk assessment in accordance with Article 11(1) and control procedures referred to in Article 11(2), when selecting monitoring methods, the operator shall give preference to monitoring methods that give most reliable results, minimise the risk of data gaps, and are least prone to inherent risks, including control risks. The selected method shall be documented in the monitoring methodology plan.
