Red shifted high velocity gas components (HVC) were detected in spectra of nine out of a survey of 47 stars. The properties of gas density and thickness of the material responsible for the HVC appear quite similar to those derived from direct observations of supernova remnants (SNR). The majority of the survey stars whose spectra show HVC lie close to the Galactic plane near l = 88 to 110 deg. A distance estimate places the HVC material within 190 pc. The improved mapping of the sky and the distance estimate to the HVC material are discussed in terms of an association with nearby radio loops. The possibility that the material may be produced by two interacting SNR (Loops 2 and 3) is considered.
