In the first three years of operation STIS obtained slitless spectra ofapproximately 2500 fields in parallel to prime HST observations as part of the STIS Parallel Survey (SPS). The archive contains almost 300 fields at highgalactic latitude (|b|>30) with spectroscopic exposure times greater than 3000seconds. This sample contains 220 fields (excluding special regions andrequiring a consistent grating angle) observed between 6 June 1997 and 21September 2000, with a total survey area of about 160 square arcminutes. Atthis depth, the SPS detects an average of one emission line galaxy per threefields. We present the analysis of these data, and the identification of 131low to intermediate redshift galaxies detected by optical emission lines. Thesample contains 78 objects with emission lines that we infer to be redshifted[OII]3727 emission at 0.43
