The Secretary of State may, after consultation with the Corporation, make regulations with respect to the action to be taken by the Corporation for alleviating cases of hardship suffered as a result of property being blighted by subsidence damage or the possibility of such damage.
The action which may be required by the regulations is—
the purchase of any blighted property at a price equivalent to its unblighted value; or
the payment of an amount equivalent to the difference between the value of any such property and its unblighted value.
Regulations under this section may make provision as to—
the making of claims under the regulations and the descriptions of persons who may make them;
the descriptions of property in respect of which such claims may be made and the circumstances in which such property is to be regarded as blighted for the purposes of the regulations;
the circumstances in which action is or is not required to be taken (including the circumstances in which a person is to be regarded as suffering hardship);
the determination of the value or unblighted value of any blighted property.
In this section "unblighted value", in relation to any blighted property, means the value which it would have if it were not blighted.
