We are requesting time through the NOAO Survey Program to carry out an extensive program of narrow-band H(alpha) imaging. Our two primary goals are to derive the most accurate value possible for the local star- formation rate (SFR) density and to explore possible environmental impacts on galaxian star-formation properties. Both projects require large, unbiased samples of galaxies. Our target sample is drawn from ALFALFA, a blind HI survey being carried out using the Arecibo 305-m radio telescope. We argue that this HI-selected sample provides the best available catalog of sources to be used for measuring SFRs. We have constructed a volume-limited sample of HI-detected objects (553 galaxies). Data for this new sample will be combined with the images from our ongoing narrow-band project currently taking place on the WIYN 0.9-m telescope to yield the largest (>1100), most comprehensive sample of H(alpha) images available beyond the Local Supercluster. We will also be able to use the survey data to address a number of important issues regarding galaxy evolution. All data from both projects will be made available to the community.
