The operator shall, without undue delay and in any event not later than 48 hours thereafter, notify the competent authority of any events likely to affect the stability of the waste facility and any significant adverse environmental effects revealed by the control and monitoring procedures of the waste facility. The operator shall implement the internal emergency plan, where applicable, and follow any other instruction from the competent authority as to the corrective measures to be taken.
The operator shall bear the costs of the measures to be undertaken.
At a frequency to be determined by the competent authority, and in any event at least once a year, the operator shall report, on the basis of aggregated data, all monitoring results to the competent authorities for the purposes of demonstrating compliance with permit conditions and increasing knowledge of waste and waste facility behaviour. On the basis of this report the competent authority may decide that validation by an independent expert is necessary.
