414.1599 Diversion programs; determination of need.—If federal regulations require a determination of needy families or needy parents to be based on financial criteria, such as income or resources, for individuals or families who are receiving services, one-time payments, or nonrecurring short-term benefits, the department shall adopt rules to define such criteria. In such rules, the department shall use the income level established for Temporary Assistance for Needy Families funds which are transferred for use under Title XX of the Social Security Act. If federal regulations do not require a financial determination for receipt of such benefits, payments, or services, the criteria otherwise established in this chapter shall be used.
