State Formula Allocations for Sewer Overflow and Stormwater Reuse 
Grants

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is announcing the 
allocation formula for the Sewer Overflow and Stormwater Reuse 
Municipal Grants Program as required by the Clean Water Act (CWA). EPA 
is required to establish a formula to allocate proportional shares of 
the amount appropriated to state entities to fund actions that will 
help manage combined sewer overflows, sanitary sewer overflows, and 
stormwater. EPA was directed to develop a formula based on the relevant 
infrastructure needs submitted in the latest Clean Watersheds Needs 
Survey (CWNS) along with additional information considered appropriate 
by the EPA Administrator. A summary of the formula is included in this 
document. This document reflects EPA's consideration of public comments 
received in response to its August 4, 2020 Federal Register 
publication.

FOR FURTHER INFORMATION CONTACT: For additional information, please 
contact Michael Goralczyk, Office of Water (mail code 4204M), 
Environmental Protection Agency, 1200 Pennsylvania Avenue NW, 
Washington, DC 20460; telephone number: 202-564-7347; or email:

I. Background

    The America's Water Infrastructure Act (AWIA) of 2018 aims to 
improve water quality, expand infrastructure investments, enhance 
public health, increase jobs, and bolster the economy. Section 4106 of 
the AWIA amended Section 221 of the Clean Water Act (CWA) to 
reauthorize the Sewer Overflow and Stormwater Reuse Municipal Grants 
Program. This amended statute directs EPA to award grants to the 
states, the District of Columbia, and U.S. territories (collectively 
referred to as ``states'') for the purpose of providing grants to a 
municipality or municipal entity for planning, design, and 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.
    EPA announced a proposed formula and methodology in the Federal 
Register on August 4, 2020 (85 FR 47205), and requested public comment 
on the methodology of this allotment formula including the factors and 
data used in determining CSO, SSO, and stormwater infrastructure needs. 
The final formula announced in this document reflects EPA's 
consideration of public comments. EPA's response to comments is 
available at https://www.regulations.gov/, Docket ID No. EPA-HQ-OW-
2020-0282.

II. Statutory Language for the Allocation Formula

    According to the CWA, funds appropriated for this program shall be 
allocated to the states according to their total proportional needs for 
municipal CSOs, SSOs, and stormwater as identified in the most recent 
CWNS and any other additional information considered appropriate by the 
EPA Administrator. This is described in Section 221(g)(2) of the CWA:

``the Administrator shall use the amounts appropriated to carry out 
this section for fiscal year 2020 and each fiscal year thereafter 
for making grants to States under subsection (a)(1) in accordance 
with a formula to be established by the Administrator, after 
providing notice and an opportunity for public comment, that 
allocates to each State a proportional share of such amounts based 
on the total needs of the State for municipal combined sewer 
overflow controls, sanitary sewer overflow controls, and stormwater 
identified in the most recent detailed estimate and comprehensive 
study submitted pursuant to section 516 of this title and any other 
information the Administrator considers appropriate.''

    The CWNS includes documented infrastructure needs. However, the 
most recent CWNS in 2012 did not include complete CSO, SSO, and 
stormwater infrastructure needs for every state and territory. In order 
to equitably allocate appropriated funds based on existing 
infrastructure needs, as directed in the amended Section 221 of the 
CWA, it is appropriate to include additional factors to fully 
characterize needs for CSOs, SSOs, and stormwater management. EPA 
consulted with state representatives and EPA regional coordinators 
experienced in managing EPA grants at the state level on a series of 
supplemental factors. With the feedback of these partners, EPA selected 
three additional factors based on the common availability of data 
across the states and the ability of these factors to serve as 
surrogates for CSO, SSO, and stormwater infrastructure needs. The three 
additional factors are annual average precipitation, total population, 
and urban population. The rationale for these additional factors 
includes the following:
    (1) Annual average precipitation is a factor because higher amounts 
of precipitation lead to greater CSO, SSO, and stormwater 
infrastructure needs to manage greater flows.
    (2) Total population is a factor because the larger the population 
of a state, the more infrastructure is generally required to serve 
them.
    (3) Urban population is a factor because there are relatively 
higher CSO, SSO, and stormwater infrastructure needs in urban 
environments from increased impervious surfaces, which generate 
increased wet weather flows during precipitation events.
    When combined with the needs determined in the CWNS, these three 
factors improve the representation of the CSO, SSO, and stormwater 
infrastructure needs in each state. This collective approach for 
assessing CSO, SSO, and stormwater infrastructure needs is the basis 
for this proposal on how to derive an allocation formula for 
appropriating funds for this program.

III. Allocation Formula

    EPA will use the following methodology to allocate appropriated 
funds to the states for the Sewer Overflow and Stormwater Reuse 
Municipal Grant Program.

Methodology

    1. Reserve 1% of the federal appropriation for EPA's administrative 
expenses per Section 221(h) of the CWA.

[[Page 11288]]

    2. Allocate the remaining amount (federal appropriation minus EPA 
administrative set-aside) based on several factors to characterize the 
``need allocation'' of each state. In addition to the most recent CWNS, 
EPA chose additional objective factors to help characterize the 
infrastructure needs of each state, as permitted by CWA Section 
221(g)(2). EPA assigned weights to each of the factors in the 
allocation formula. The CWNS needs are weighted at 50% and the 
additional factors were weighted evenly to collectively account for the 
remaining 50%. The combination of the following factors forms the need 
allocation for each state.
    [ssquf] Clean Watersheds Needs Survey: This factor is included as 
the statute directs EPA to use the needs submitted pursuant to CWA 
Section 516. Each allocation year, EPA will use the latest available 
CWNS information that provides a comprehensive assessment of CSOs, 
SSOs, and stormwater infrastructure needs. This factor represents 50% 
of the need allocation as these needs were directly identified in the 
survey.
    [ssquf] Annual Average Precipitation: This factor is included to 
account for the volume of annual precipitation a state receives which 
suggests the amount of stormwater runoff that needs to be managed. This 
factor represents 16.67% of the need allocation.
    [ssquf] Total Population: This factor is included to represent the 
proportional need of each state's population size acknowledging that 
higher populations generally have greater infrastructure needs. This 
factor represents 16.67% of the need allocation.
    [ssquf] Urban Population: This factor is included to represent the 
needs that urban centers have for CSOs, SSOs, and stormwater management 
due to high concentrations of impervious surfaces. This factor 
represents 16.67% of the need allocation.
    3. Adjust the allocation proportions to ensure that no state 
receives an allocation below 0.5%. Any adjustments to raise states to 
this base allocation amount will be taken at a proportional basis from 
states that were above this base amount. Once adjustments are made to 
ensure that each state receives at least 0.5% of the remaining amount 
(federal appropriation minus EPA administrative set-aside), this 
allocation will be considered the final state allocation for the 
applicable fiscal year.
    In following this methodology, the results for each state's 
allocation proportion are shown in Table 1.
