Section 990.240 - General(a) PHAs will be provided opportunities for appeals. HUD will provide up to a two percent hold-back of the Operating Fund appropriation for FY 2006 and FY 2007. HUD will use the hold-back amount to fund appeals that are filed during each of these fiscal years. Hold-back funds not utilized will be added back to the formula within each of the affected fiscal years.(b) Appeals are voluntary and must cover an entire portfolio, not single projects. However, the Assistant Secretary for Public and Indian Housing (or designee) has the discretion to accept appeals of less than an entire portfolio for PHAs with greater than 5,000 public housing units.
