31. Grounds for the cancellation of a licence

A licence issued by the Council may at any time by a notification sent to the licencee in that behalf, be cancelled where-

the licencee has acted in violation of any condition of the licence or in contravention of any provision of this Act or any regulation or rule made thereunder, which pose an unacceptable threat or risk to public health or a danger to the environment;

the licencee has failed without reason, to comply with any directives issued by the Council under section 39;

the licencee has ceased to conduct or operate the practice for which the licence was issued;

due to any prevailing circumstances the Council determines that the continued conduct of the practice for which the licence was issued, would pose an unacceptable threat or risk to public health or a danger to the environment; or

the receiving environment has altered or changed due to certain natural and other causes which renders the continued conduct of the practice a risk to public health or a danger to the environment.
