[F1Article 8a U.K.
1. The decision to grant development consent shall incorporate at least the following information:
(a) the reasoned conclusion referred to in Article 1(2)(g)(iv);
(b) any environmental conditions attached to the decision, a description of any features of the project and/or measures envisaged to avoid, prevent or reduce and, if possible, offset significant adverse effects on the environment as well as, where appropriate, monitoring measures.
2. The decision to refuse development consent shall state the main reasons for the refusal.
3. In the event Member States make use of the procedures referred to in Article 2(2) other than the procedures for development consent, the requirements of paragraphs 1 and 2 of this Article, as appropriate, shall be deemed to be fulfilled when any decision issued in the context of those procedures contains the information referred to in those paragraphs and there are mechanisms in place which enable the fulfilment of the requirements of paragraph 6 of this Article.
4. In accordance with the requirements referred to in paragraph 1(b), Member States shall ensure that the features of the project and/or measures envisaged to avoid, prevent or reduce and, if possible, offset significant adverse effects on the environment are implemented by the developer, and shall determine the procedures regarding the monitoring of significant adverse effects on the environment.
The type of parameters to be monitored and the duration of the monitoring shall be proportionate to the nature, location and size of the project and the significance of its effects on the environment.
Existing monitoring arrangements resulting from Union legislation other than this Directive and from national legislation may be used if appropriate, with a view to avoiding duplication of monitoring.
5. Member States shall ensure that the competent authority takes any of the decisions referred to in paragraphs 1 to 3 within a reasonable period of time.
6. The competent authority shall be satisfied that the reasoned conclusion referred to in Article 1(2)(g)(iv), or any of the decisions referred to in paragraph 3 of this Article, is still up to date when taking a decision to grant development consent. To that effect, Member States may set time-frames for the validity of the reasoned conclusion referred to in Article 1(2)(g)(iv) or any of the decisions referred to in paragraph 3 of this Article.]
