Electron-impact excitation cross sections for $\mathrm{OI}({}_{}{}^3{}_{}{}^{}P-3s{}_{}{}^3{}_{}{}^{}S_{}^0{}_{}{}^{})$ are calculated in unitarized Born, nonexchange, and close-coupling approximations. The close-coupling cross sections have the same energy dependence as measurements by Stone and Zipf but are lower in magnitude by a factor of 4. Two autodetaching levels of ${\mathrm{O}}^{-}\left[2\mathrm{}{p}^3\right({}_{}{}^4{}_{}{}^{}S_{}^0{}_{}{}^{}\left)3s3p{}_{}{}^{2,4}{}_{}{}^{}P\right]$ are found at 9.67 and 9.94 eV. The doublet state is tentatively identified as a state found experimentally by Edwards at 9.52 eV.
