No waste facility shall be allowed to operate without a permit granted by the competent authority. The permit shall contain the elements specified in paragraph 2 of this Article and shall clearly indicate the category of the waste facility in accordance with the criteria referred to in Article 9.
Subject to compliance with all requirements under this Article, any permit produced pursuant to other national or Community legislation may be combined to form a single permit, where such a format obviates the unnecessary duplication of information and the repetition of work by the operator or competent authority. The details specified in paragraph 2 can be covered by one single permit or several permits, provided that all requirements under this Article are complied with.
