Section 570.4 - Allocation of funds(a) The determination of eligibility of units of general local government to receive entitlement grants, the entitlement amounts, the allocation of appropriated funds to States for use in nonentitlement areas, the reallocation of funds, the allocation of appropriated funds to insular areas, and the allocation of appropriated funds for discretionary grants under the Secretary's Fund shall be governed by the policies and procedures described in sections 106 and 107 of the Act, as appropriate.(b) The definitions in § 570.3 shall govern in applying the policies and procedures described in sections 106 and 107 of the Act.(c) In determining eligibility for entitlement and in allocating funds under section 106 of the Act for any federal fiscal year, HUD will recognize corporate status and geographical boundaries and the status of metropolitan areas and principal cities effective as of July 1 preceding such federal fiscal year, subject to the following limitations: (1) With respect to corporate status as certified by the applicable State and available for processing by the Census Bureau as of such date;(2) With respect to boundary changes or annexations, as are used by the Census Bureau in preparing population estimates for all general purpose governmental units and are available for processing by the Census Bureau as of such date, except that any such boundary changes or annexations which result in the population of a unit of general local government reaching or exceeding 50,000 shall be recognized for this purpose whether or not such changes are used by the Census Bureau in preparing such population estimates; and(3) With respect to the status of Metropolitan Statistical Areas and principal cities, as officially designated by the Office of Management and Budget as of such date.(d) In determining whether a county qualifies as an urban county, and in computing entitlement amounts for urban counties, the demographic values of population, poverty, housing overcrowding, and age of housing of any Indian tribes located within the county shall be excluded. In allocating amounts to States for use in nonentitlement areas, the demographic values of population, poverty, housing overcrowding and age of housing of all Indian tribes located in all nonentitled areas shall be excluded. It is recognized that all such data on Indian tribes are not generally available from the United States Bureau of the Census and that missing portions of data will have to be estimated. In accomplishing any such estimates the Secretary may use such other related information available from reputable sources as may seem appropriate, regardless of the data's point or period of time and shall use the best judgement possible in adjusting such data to reflect the same point or period of time as the overall data from which the Indian tribes are being deducted, so that such deduction shall not create an imbalance with those overall data.(e) Amounts remaining after closeout of a grant which are required to be returned to HUD under the provisions of § 570.509 , Grant closeout procedures, shall be considered as funds available for reallocation unless the appropriation under which the funds were provided to the Department has lapsed.53 FR 34437, Sept. 6, 1988, as amended at 68 FR 69582 , Dec. 12, 2003; 69 FR 32778 , June 10, 2004
