What the program funds
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).

Matching requirements
This program has no statutory formula. The Federal share for awards shall be 80% of the total award. Non-Federal share requirements cannot be passed on to rural communities and financially distressed communities. Recipients are required to provide a non-federal cost share/match for the remaining 20% of the total award, unless reduced by EPA after verifying that funds will support Rural (population of 10,000 of less) and/or Financially Distressed communities as defined by the state as described in 33 USC 1301(d)(2). Sources of Cost Share: statutory language in 33 USC 1301(d) describes: …The non-Federal share of the cost may include, in any amount, public and private funds and in-kind services, and may include, notwithstanding 33 USC 1383(h), financial assistance, including loans, from a State water pollution control revolving fund (CWSRF).” OSG-related expenses paid by the CWSRF fee accounts, held outside the Fund, may also be used as personal expenses provided, they are appropriately identified in the CWSRF Intended Use Plan (IUP) and CWSRF annual report. A CWSRF loan (including additional subsidization) to the same subrecipient or different subrecipients may be used to meet the cost share requirement. Only non-equivalency CWSRF agreements may be used. CWSRF proportionality rules do not apply to OSG grant funds. Recipients may coordinate with their EPA Regional Office for support in implementing Cost Share requirements. This program does not have a statutory formula.
