This program provides 100% grant funding for eligible projects that fall under CWA section 603(c), which is similar to the Clean Water State Revolving Fund. The OSG program has limited funding and allocations are typically released once per federal fiscal year. Eligible entities for this grant opportunity are municipalities or municipal entities. To apply, applicants should use the CWSRF application and indicate OSG as the funding source. The Construction Programs Bureau will maintain a list of eligible applicants for the OSG program.
