Potocnik said that two proceedings against Slovenia dealt with slow implementation of EU legislation, three with incomplete implementation and one with incorrect implementation.

The latter, which is the most important according to the commissioner, was the directive on water protection and management, dealing with identifying all the river basins covering the area of more than one member state.

He moreover said that Slovenia did not have to be warned more than once, meaning that motions did not have to be brought at the European Court of Justice.

Slovenia is mostly successful in implementing European legislation and "does not deviate on the downside from other countries," Potocnik added.

He believes Slovenia is "a normal EU member that sometimes has problems with implementing legislation in time, but is definitely trying hard to meet its responsibilities".

Potocnik however believes that Slovenia has the most trouble with managing waste and with air quality.

According to him, these are serious problems, while others, like trouble in implementing legislation, happen at the same level as with other members of the bloc.

Slovenia was late in implementing EU legislation on the quality of ambient air and cleaner air for Europe and the directive on sorting, marking and packaging substances and mixtures.

The three procedures dealing with Slovenia's incomplete implementation of legislation was related to the directive on managing mining and other extracting waste, the directive on packaging and packaging waste, and the directive on end-of-life-vehicles.
