Section 1000.336 - How may an Indian tribe, TDHE, or HUD challenge data or appeal HUD formula determinations?(a) An Indian tribe, TDHE, or HUD may challenge data used in the IHBG Formula and HUD formula determinations regarding:(4) Formula Current Assisted Stock (FCAS);(5) Total Development Cost (TDC);(6) Fair Market Rents (FMRs);(7) Indian Health Service projections based upon birth and death rate data provided by the National Center for Health Statistics; and(8) The undisbursed funds factor.(b) An Indian tribe or TDHE may not challenge data or HUD formula determinations regarding Allowable Expense Level (AEL) and the inflation factor.(c) The challenge and the collection of data and the appeal of HUD formula determinations is an allowable cost for IHBG funds.(d) An Indian tribe or TDHE that seeks to appeal data or a HUD formula determination, and has data in its possession that are acceptable to HUD, shall submit the challenge or appeal in writing with data and proper documentation to HUD. An Indian tribe or TDHE may appeal the undisbursed funds factor no later than 30 days after the receipt of the formula determination. Data used to challenge data contained in the U.S. Census must meet the requirements described in § 1000.330(a) . Further, in order for a census challenge to be considered for the upcoming fiscal year allocation, documentation must be submitted by March 30th.(e) HUD shall respond to all challenges or appeals no later than 45 days after receipt and either approve or deny the appeal in writing, setting forth the reasons for its decision. (1) If HUD challenges the validity of the submitted data HUD and the Indian tribe or TDHE shall attempt in good faith to resolve any discrepancies so that such data may be included in the formula allocation.(2) If HUD denies a challenge or appeal, the Indian tribe or TDHE may request reconsideration of HUD's denial within 30 calendar days of receipt of HUD's denial. The request shall be in writing and set forth justification for reconsideration.(3) HUD shall in writing affirm or deny the Indian tribe's or TDHE's request for reconsideration, setting forth HUD's reasons for the decision, within 20 calendar days of receiving the request. HUD's denial of a request for reconsideration shall constitute final agency action.(4) If HUD approves the Indian tribe or TDHE's appeal, HUD will adjust to the Indian tribe's or TDHE's subsequent fiscal year allocation to include only the disputed fiscal year(s).(f) In the event HUD questions whether the data contained in the formula accurately represents the Indian tribe's need, HUD shall request the Indian tribe to submit supporting documentation to justify the data and, if applicable, to provide a commitment to serve the population indicated in the geographic area. 72 FR 20025 , Apr. 20, 2007, as amended at 81 FR 83681 , Nov. 22, 2016 As amended at 81 FR 83681, 11/22/2016
