Section 8 Portability Process: Fill & Download for Free

No, maybe, yes.Only the agency that issued your Section 8 Housing Choice Voucher knows for sure."Portability" in the Housing Choice Vouchers (HCV) program refers to the process through which the family can transfer or "port" their rental subsidy when they move to a location outside the jurisdiction of the public housing agency (PHA) that first gave them the voucher when they were selected for the program.New families may not be able to port immediately; they may have to live in the jurisdiction of the initial PHA for a year before they can port. Initial PHAs may allow moves during this one-year period.Initial PHAs -The PHA that first gave the voucher to the individual when they were selected for the program.Receiving PHAs- The agency that will administer assistance in the area to which the individual moves.https://www.hud.gov/sites/documents/PORTABILITYRULE.PDF (12 page document)

Yes. Housing Choice Vouchers are portable.A Section 8 Housing Choice Voucher holder may transfer their voucher to a different area once specific conditions are met. This process is referred to as "portability."A HCV participant may only port out to a different area after one year of residency in the jurisdiction of the housing authority that issued the voucher. If the voucher holder was a resident in the jurisdiction when they initially applied for the voucher, they may request to port out to a different jurisdiction at any time. (For example, if you live in New York City, New York, and apply for the Chicago Housing Authority Section 8 waiting list in Illinois, you must live within the Chicago Housing Authority's jurisdiction with your voucher for 12 months before porting. But, if you live in Chicago, IL and apply for the Chicago Housing Authority Section 8 waiting list, you may port to a new area any time after you receive your voucher.)When searching for a new a new area, it's important to know the Section 8 Housing Choice Voucher income qualifications, as well. If your household does not qualify for the housing authority's income limits, you may not port there.Housing authorities are given a lot of leeway by HUD in their porting policy, so there may be other specific factors required to be able to port your voucher.To begin this process, you must first contact the housing authority that currently manages your voucher. You will then be instructed to contact the housing authority that serves the area you are interested in moving to. — How Do I Find a Unit After Receiving My Voucher?—-An eligible family that has been issued a housing choice voucher [section 8] may use that voucher to lease a unit anywhere in the United States where there is a housing agency operating a housing choice voucher program. — https://www.hud.gov/sites/documents/DOC_35623.PDF—-Yes, you can take your Section 8 Housing Choice Voucher to a different area once specific conditions are met. This process is referred to as "portability." You can read more about HUD's portability policy here.

Such a device would be an interesting bit of chemical engineering. In effect, you would need to build a small chemical processing plant to fit on the back of a diver.The concentration of dissolved oxygen in water in equilibrium with air is about 10 mg/liter at 15 deg C. This goes up at colder temperatures (almost 15 mg/liter at freezing) and down for higher temperatures (7.5 mg/liter at 30 deg C). Seawater in tropical regions with plant life normally has 5–8 mg of oxygen per liter.NASA estimates a human consumes about 550 liters per day of pure oxygen, or about 0.38 liters/min. Combat swimmers, swimming at their own pace, consume about 1.5 liters/min, decreasing to about 0.64 liters/min for resting divers. The U.S. Navy Diving Manual (Table 3.4) quotes values between 0.8 and 1.8 liters/min for swimmers. Based on this information, extracting 1 liter of oxygen (about 1.4 grams) per minute would be a minimum requirement to support meaningful underwater activity.Assuming 100% recovery, that amount of oxygen would require processing 2.9-4.7 liters of water per second. As I will explain below, a 30% recovery is about the most that could be achieved without requiring mechanical expansion and recompression of the breathing gas. 30% recovery would require processing between 10 and 15 liters of water per second. This is a formidable flowrate for a portable device. A typical garden hose, for example, has a flow rate of about 1.5 liters per second.To put this flowrate in context, the swimming speed of a skilled scuba diver swims is about 0.5 m/s. At that speed, a 15 liter/sec flow rate corresponds to a circular cross-section of 20 cm. So if a device could be constructed with minimal pressure drop, the diver’s forward speed might be enough to provide the necessary water flow. (Like a shark, if you think about it.)Permselective membranes for oxygen have been developed with permeabilities of 10**-8 cc*cm/cm2/sec/cmHg. (c.f., Highly Oxygen Permselective Membrane of Cobalt-Complexed Polyazomethine Containing Tridentate Ligand and Oligosiloxane in the Repeating Pairs of the Main Chain)We’ll make the following assumptions:Recover 30% of the oxygen in a countercurrent device, and maintain a partial pressure difference of 0.30*.21*760 = 4.8 cm Hg for the length of the device.A supported membrane 1 (= 0.0001cm) micron thick.A demand of 16.7 cc of oxygen per sec (equivalent to 1 liter of oxygen/minute).The device will be used at relatively shallow depths to avoid issues of oxygen toxicity and nitrogen narcosis.With these assumptions, the required membrane area would be 16.7*0.0001/4.8/10**-8= 35,000 square centimeters or 3.5 square meters of membrane surface area. This amount of area fits comfortably into a hollow fiber membrane module such as this oneThe problem here is liquid handling. Pumping 4 liter/sec through a small module like this would require a large pressure drop, perhaps enough to ruin the membrane.Fortunately, 3M sells larger hollow membrane modules designed for liquid degassing (3M™ Liqui-Cel™ Operating and Technical Guides). Their technical guides suggest an 8″ diameter (i.e, 20 cm) module at least 1 meter in length.The gas handling is more complex. The minimum partial pressure of breathing oxygen for divers is 0.16 bar. Assuming the surrounding water is equilibrated with the atmosphere for an oxygen partial pressure of 0.20 bar, a difference of 0.04 bar is available to drive oxygen mass transfer across the membrane. For humans, the partial pressure of oxygen leaving the lungs is typically 0.10 bar. For a countercurrent membrane separator in which the water and liquid gas streams move in opposite directions, the exit water would have a partial pressure no less than 0.10 bar. Parsimonious design suggests a constant driving force for mass transfer of 0.04 established at the entrance so we can estimate the exit water partial pressure of about 0.14 bar. On that basis, the maximum practical oxygen recovery is about 0.06/0.20 or 30%.Achieving higher recoveries would require a method to reduce the gas pressure, such as a mechanical device to expand then recompress the gas. The energy requirement for that mechanical device would be prohibitive. Some type of thermal cycling chemical separator, or a stripper/absorber might be possible, but again energy considerations would come into play.A second issue is that gas separation is only adequate to replace the consumed oxygen. A rebreathing apparatus will be needed to scrub out the carbon dioxide produced by the diver’s metabolism and recycle unconsumed oxygen. Fortunately, commercial rebreathing gear is available. Rebreather - WikipediaAn alternative to gas membrane separation might be to use an intermediate carrier fluid. This was proposed in the 1980’s using actual human hemoglobin, fish blood, and other carriers. The issue is in coming up with the right compound, and being able to perform the necessary liquid-liquid processing in a portable device.So a self-contained diving device to extract oxygen from water may be plausible. But make no mistake, significant engineering development would be required to adapt existing technologies into an apparatus suitable for practical underwater use.ADDENDUM: Wow, 3k upvotes!
