The failure, neglect or refusal of a tenant to furnish information concerning his income or that of any member of his household, or to cooperate in the verifying of such reported income will be considered as non-cooperation and will be assumed to indicate excess income. Such tenant will be notified of his ineligibility, increased to the vacating rent, and legal action taken to obtain his eviction as not complying with the rules and regulations of the authority. However, upon submission of proper documents, surcharges, if any, will be assessed on basis of verified income. In no event will credit be given for excess surcharges already assessed as a result of failure, neglect or refusal of tenant to cooperate in income determination as set forth in this section.
