40 CFR § 35.2152 - Federal share.
(a) General. The Federal share for each project shall be based on the sum of the total Step 3 or Step 7 allowable costs and the allowance established in the grant agreement under appendix B. Except as provided elsewhere in this section, the Federal share shall be:
(1) 75 percent for grant assistance awarded before October 1, 1984;
(2) 55 percent for grant assistance awarded after September 30, 1984, except as provided in paragraph (a)(3) of this section; and
(3) Subject to paragraphs (c) and (d) of this section, 75 percent for grant assistance awarded after September 30, 1984 and before October 1, 1990, for sequential phases or segments of a primary, secondary, or advanced treatment facility or its interceptors, or infiltration/inflow correction provided:
(ii) The Step 3 grant for the initial phase or segment of the treatment works described in (a)(3)(i) of this section is awarded prior to October 1, 1984; and
(iii) The phase or segment that receives 75 percent funding is necessary to (A) make a phase or segment previously funded by EPA operational and comply with the enforceable requirements of the Act, or (B) complete the treatment works referenced in (a)(3)(i) of this section provided that all phases or segments previously funded by EPA are operational and comply with the enforceable requirements of the Act.
(b) Innovative and alternative technology. In accordance with § 35.2032, the Federal share for eligible treatment works or unit processes and techniques that the Regional Administrator determines meet the definition of innovative or alternative technology shall be 20 percent greater than the Federal share under paragraph (a) or (c) of this section, but in no event shall the total Federal share be greater than 85 percent. This increased Federal share depends on the availability of funds from the reserve under § 35.2020. The proportional State contribution to the non-Federal share of building costs for I/A projects must be the same as or greater than the proportional State contribution (if any) to the non-Federal share of eligible building costs for all treatment works which receive 75 or 55 percent grants or such other Federal share under paragraph (c) of this section in the State.
(c) A project for which an application for grant assistance has been made before October 1, 1984, but which was under judicial injunction at that time prohibiting its construction, shall be eligible for a grant at 75 percent of the cost of its construction.
(d) Uniform lower Federal share.
(1) Except as provided in § 35.2032 (c) and (d) of this section, the Governor of a State may request the Regional Administrator's approval to revise uniformly throughout the State the Federal share of grant assistance for all future projects. The revised Federal share must apply to all needs categories (see § 35.2015(b)(2)).
(e) Training facilities. The Federal share of treatment works required to train and upgrade waste treatment works operations and maintenance personnel may be up to 100 percent of the allowable cost of the project.
(1) Where a grant is made to serve two or more States, the Administrator is authorized to make an additional grant for a supplemental facility in each State. The Federal funds awarded to any State under section 109(b) for all training facilities shall not exceed $500,000.
(2) Any grantee who received a grant under section 109(b) before December 27, 1977, may have the grant increased up to $500,000 by funds made available under the Act, not to exceed 100 percent of the allowable costs.
