(3) The closure procedure shall begin –

(a) when the conditions specified in the landfill permit are satisfied

(c) by a reasoned decision of the Chief Inspector which shall be set out in a closure notice served on the operator in accordance with regulation 16.

(b) the Chief Inspector –

(i) has assessed all the reports submitted by the operator;

(ii) has carried out a final on-site inspection; and

(iii) has notified the operator by notice in writing that he approves the closure.

(5) Following definitive closure of a landfill, after-care procedures shall ensure that –

(a) the operator remains responsible for the maintenance, monitoring and control for such period as the Chief Inspector determines is reasonable, taking into account the time during which the landfill could present hazards;

(b) the operator notifies the Chief Inspector of any significant adverse environmental effects revealed by the control procedures and takes the remedial steps required or approved by the Chief Inspector; and

(c) the operator is responsible for monitoring and analysing landfill gas and leachate from the landfill and the groundwater regime in its vicinity in accordance with Schedule 3 for as long as the Chief Inspector considers that the landfill is likely to cause a hazard to the environment.

(7) The operator shall not be relieved from liability under the conditions of the landfill permit by reason of the Chief Inspector’s approval of closure under paragraph (4)(b)(iii).
