Greenhouse Gas Reduction Fund: Clean Communities Investment Accelerator is sponsored by ENVIRONMENTAL PROTECTION AGENCY. The Inflation Reduction Act amends the Clean Air Act to include Section 134 (42 USC § 7434), which authorizes the EPA to make competitive grants under the Clean Communities Investment Accelerator.
The Clean Communities Investment Accelerator is currently funded by $6 billion from Section 134(a)(3) (out of $8 billion provided in Section 134(a)(3)). The Clean Communities Investment Accelerator implements the statute’s use of funds for indirect investments under Section 134(b)(2).
Section 134(b)(2) directs recipients of funds for indirect investments to provide funding and technical assistance to establish new or support existing public, quasi-public, not-for-profit, or nonprofit entities that provide financial assistance to qualified projects at the State, local, territorial, or Tribal level or in the District of Columbia, including community- and low-income-focused lenders and capital providers.
Section 134(c)(3) provides that a qualified project is any project, activity or technology that (A) reduces or avoids greenhouse gas emissions or other forms of air pollution in partnership with, and by leveraging investment from, the private sector; or (B) assists communities in the efforts of those communities to reduce or avoid greenhouse gas emissions and other forms of air pollution.

On June 29, 2026, EPA announced it will waive the $25,000 WIFIA application fee and the credit processing fee — averaging roughly $156,000 per loan — for communities of 25,000 or fewer residents in fiscal years 2026 and 2027. Combined, that removes nearly $200,000 in upfront cost from the single most affordable federal water-infrastructure financing program, which carries roughly $11 billion in available capacity and can cover up to 80% of eligible project costs at Treasury-rate pricing. For small towns, rural utilities, and the nonprofits and districts that serve them, this is a rare instance of the federal government lowering the barrier to a program that has historically been out of reach for exactly the communities that need it most. Here is what changed, who qualifies, and how to move on a letter of interest before the window closes.
Read articleFor FY2026 and FY2027, EPA is waiving the $25,000 WIFIA application fee and the ~$156,000 credit-processing fee for water systems serving 25,000 or fewer people — a near-$200,000 discount on access to an $11 billion pool of low-cost federal financing. The waiver removes the single barrier that kept small and rural utilities out of WIFIA for a decade. Here is how WIFIA actually works, who qualifies, why the letter of interest is the real gate, and how a town of 8,000 should think about a program built for billion-dollar projects.
Read articleFor FY2026 and FY2027, EPA is waiving the WIFIA application and credit-processing fees for communities of 25,000 or fewer — saving nearly $200,000 per loan — against roughly $11 billion in flexible financing that covers up to 80 percent of project costs. Here is why WIFIA has been underused by small systems, how the loan actually works, and how a rural utility should build a WIFIA strategy in 2026.
