SBA Releases Final Rule Allowing WOSB and EDWOSB Sole Source
Effective October 14, 2015, the sole source authority will be allowed for industries in which WOSB or EDWOSB set-asides are authorized, and the CO – through market research – cannot identify two or more WOSBs or EDWOSBs that can perform the requirement at a fair and reasonable price but does identify one WOSB or EDWOSB that can perform. The sole source authority for WOSBs and EDWOSBs is limited to contracts valued at $6.5 million or less for manufacturing and $4 million or less for all other procurements.
