Program objective
The objective of the OSG Program is to award grants to the states, the District of Columbia, and U.S. territories for the purpose of providing grants to a municipality or municipal entity for the planning, design, or construction of: 1) treatment works to intercept, transport, control, treat, or reuse municipal combined sewer overflows (CSOs), sanitary sewer overflows (SSOs), or stormwater; and 2) any other measures to manage, reduce, treat, or recapture stormwater or subsurface drainage water. State recipients shall continue to provide funding to municipalities based on the following priorities: 1. financially distressed communities that meet the affordability criteria established by the state; 2. implementing a long-term control plan for CSOs or SSOs; 3. requesting funds for a project included on a state’s Intended Use Plan for the Clean Water State Revolving Fund; or 4. an Alaskan Native Village. State recipients may select which priorities from this list are most relevant for their program when determining which municipalities to fund. Furthermore, to the extent there are sufficient eligible project applications, at least 20% of a state’s allocation must be used for green infrastructure, water and energy efficiency improvements, or other environmentally innovative activities. To the extent there are sufficient eligible project applications, a State shall use not less than 25 percent of their allocation amount to carry out projects in rural communities or financially distressed communities. Of this 25 percent amount, at least 60 percent of this amount should go toward rural communities (Population of 10,000 or less).
