Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
P.O.- 1
INTRODUCTION
The Metropolitan St. Louis Sewer District (MSD or District) was formed on February 9, 1954,
when voters approved the Plan of the District to provide a metropolitan-wide system of wastewater
treatment and sewerage facilities for the collection, treatment, and disposal of sewage. MSD began
operations in January 1956 in an area roughly composed of the City of St. Louis and the portion
of St. Louis County located east of Interstate 270. It took over the publicly owned wastewater and
stormwater drainage facilities within its jurisdiction and began the construction of an extensive
system of collector and interceptor sewers and treatment facilities. Most of the remainder of St.
Louis County was annexed by MSD in 1977.
MSD’s Rate Commission was established in 2000. The Commission consists of 15 member
organizations that represent a broad cross-section of the customers and community MSD serves.
The Commission’s purpose is to provide public input into how MSD sets its rates. The
Commission is required by Charter to review all Rate Change Proposals (Rate Proposal(s)) and
render an opinion before submitting Rate Proposals to the Board of Trustees for approval.
The Rate Commission process includes multiple public hearings throughout the St. Louis
metropolitan area where MSD customers have an opportunity to provide feedback on the Rate
Proposal. The entire Rate Commission proceedings may take up to 165 days from the date the
District submits a Rate Proposal for consideration. All Rate Commission meetings are open to the
public. The date, time and location of Rate Commission meetings are posted on the MSD website.
MSD’s Rate Proposal is the product of the District and is based on the strategic and financial
implications of its regulatory defined Wastewater (WW) service obligations to the St. Louis region
and its ongoing stormwater operations. The District’s development of its Rate Proposal reflects
consultative and analytical assistance from Raftelis Financial Consultants, Inc. (Raftelis).

SECTION 4 – Proposed Wastewater Rates
This section provides the details of the District’s proposed change in its wastewater rates. The
District proposes the use of a combination of issuing additional revenue bonds and increasing WW
user charges to fund its WW operating and maintenance costs (O&M) as well as EPA Consent
Decree (CD) requirements and other regulatory requirements. The CD mandates the
implementation of a multi-decade Capital Improvement and Replacement Program (CIRP). The
Rate Proposal reflects capital projects and related O&M needed over the next four years to comply
with the CD. The explanation and basis for the proposed WW funding, its underlying assumptions,
resulting rates and impact on MSD customers are contained in this Section. Additional detail
supporting the assumptions used to design the proposed change in WW rates may be found in the
Appendices in Section 8.
SECTION 5 – Proposed Stormwater Capital Funding
This section provides the details of the District’s proposed plan to fund SW capital improvements
within its boundaries. Currently, the District levies two Districtwide ad valorem property taxes to
fund SW regulatory and operation and maintenance (O&M) activities, but there is no Districtwide
funding source for SW capital improvements. This Stormwater Capital Proposal includes new
funding for Districtwide SW capital improvements. Revenues for this new program will be
generated through a combination of a new ad valorem property tax on residential customers and
an impervious area-based rate for all non-residential customers. Additional details supporting the
assumptions used to determine the SW charges can be found in the Appendices in Section 8.
SECTION 6 – Customer Rate Impact
This section provides information on the impacts of the proposed rate adjustments on typical
residential, commercial and industrial customers of the District.
SECTION 7 – Alternative Proposed Wastewater Rates
This section provides information on an alternative rate scenario in the event the District’s voters
do not authorize new bonds. If voters reject the District’s proposed revenue bond authorization,
the District will need to finance its major capital improvement program on a 100% PAYGO basis.
In recognition of this possibility, financial analyses identical to those presented earlier in this
proposal were used to reflect the impact of rates without the benefits of additional bond
authorization.
SECTION 8 – Appendices
This section contains appendices providing additional detail underlying the key assumptions used
in the District’s rate design.

EXECUTIVE SUMMARY
3.1 Existing WW and SW Billing Structures
All customers pay a base charge as well as a variable volume charge based on their water usage as
provided by their respective water providers. While the billing rate is the same for all customers’
volume charge, the billing structure for customers varies depending on the method used to measure
their water usage. Customers fall within two types, metered or unmetered. Single family and multi-
family customers may be either metered or unmetered primarily based on where they live in the
St. Louis area. For the most part, single family and multi-family customers residing in St. Louis
County are metered with water usage measured in Ccf and the volume charge assessed on a per
Ccf basis. Single family and multi-family customers in the City of St. Louis are primarily
unmetered with water usage measured in attributes and the volume charge assessed on a per
attribute basis. All non-residential customers are metered. All non-residential customers also pay
a tiered compliance charge based on the amount of required environmental monitoring. Some non-
residential customers also pay extra-strength charges where applicable.
Regarding the SW billing structure, all customers pay for SW regulatory and O&M services
through ad valorem property taxes. A small portion of the District located between the City of St.
Louis municipal boundary and interstate 270 are in Operation, Maintenance, Construction, and
Improvement (OMCI) sub-districts and also pay for SW capital improvements through ad valorem
property taxes.
3.2 WW Rate Proposal Assumptions
The District’s proposed WW rates are based on rate design application and analysis conducted by
MSD’s rate consultant, Raftelis, in conjunction with District staff. The principal assumptions used
in the WW Rate Change Proposal are as follows:
1. Raftelis has relied on certain historical, financial and statistical data supplied by District staff.
While such data is considered reliable, Raftelis has not independently verified or audited the
detailed accuracy of such data.
2. Billed WW volume will decrease overall throughout the forecast period as analyzed by the
District.
3. The District’s WW O&M expense will have inflationary increases over the forecast period
as shown in Section 4.5 of this Rate Proposal and discussed in more detail in Appendix 8.1.1.
4. The District’s estimates of content, scheduling and cost of the four-year WW CIRP totaling
approximately $1.65 billion for FY 2025 through FY 2028 present a reasonable projection
of the future construction program. More details about the District’s WW CIRP can be found
in Section 4.6 of this Rate Proposal as well as Appendices 8.1.2, 8.2.1, 8.2.2, 8.2.3 and 8.2.4.
SECTION 3 – Executive Summary
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
ES- 2
5. The CIRP is primarily funded through a combination of WW service charges, WW revenue
bonds, and miscellaneous other customer fees. MSD's new rate plan, which runs from July
1, 2024 to June 30, 2028, includes increases in WW charges, as well as $507 million in senior
revenue bonds to help fund needed improvements over the forecast period. MSD will receive
limited financial support from the federal government for this construction program in the
form of $133 million in state-administered subordinate series of revenue bonds issued under
the Missouri State Revolving Fund (SRF). More details on the CIRP financing plan can be
found in Section 4.6.1.
6. A Bond election will be held in April of 2024 and the District voters will be requested to
authorize $750 million of additional WW revenue bonds.
7. If the District does not obtain additional revenue bond authority, the District will implement
the alternative WW rates presented in Table 6-3 of this report.
8. Debt service for the senior revenue bonds and SRF financing proposed to be issued during
the study period will be approximately $173 million, as estimated.
9. The District will maintain a minimum operating reserve balance at all times that is equal to
at least 60 days of operating expenditures.
3.3 WW Rate Proposal
Overall, the analyses indicate that the District will require increases in revenues averaging 7.25%
over the Rate Proposal period. The District’s complete financial forecast is presented in Table ES-
1 and discussed in Section 4.8 of this Rate Proposal.

ES- 4
Raftelis performed a detailed cost-of-service analysis using industry standard principles endorsed
by the Water Environment Federation (WEF), which allows the District to demonstrate that rates
have not been set in an arbitrary manner and one class of customer is not subsidizing another to an
unjustifiable extent, or in a manner that is not approved and supported by the District. The
District’s existing, approved, and proposed user charges are shown in Table ES-2.
Table ES-2 Wastewater User Charges
These rates will provide the District with the necessary levels of revenue while recovering the
District’s costs in a fair and equitable manner from its customers.

3.5 Total Impact on Customer Bills
Table ES-3 presents a comparison of typical WW service bills under existing rates, rates currently
approved through FY 2024, and under the proposed FY 2025 through FY 2028 rates, for various
billable WW volumes and customer classes. As indicated by this table, the monthly bill for a
typical metered single family residential customer contributing 5 Ccf of WW each month to the
sewer system is projected to increase $18.19 from FY 2024 to FY 2028 (about 7.2% on average in
each year from FY 2025 through FY 2028).

PROPOSED WASTEWATER RATES
4.1 Current Wastewater Rate Structure
The District’s current WW rate structure consists of base service charges and volume charges
applicable to all MSD customers. The base service charges include a billing and collection charge
and a system availability charge. The volume charge is assessed to all customers based on their
respective water usage. Billing data is provided by the customers’ respective water providers on
either a metered or unmetered basis. All non-residential customers are also assessed one of five
tiered compliance charges based on the amount of inspection and testing of WW needed to comply
with current regulations and extra strength surcharges where applicable. Extra strength surcharges
are applied to monitored non-residential customers generating excess biochemical oxygen demand
(BOD), chemical oxygen demand (COD), and total suspended solids (TSS).
The District’s historical and existing WW rates are presented in Table 4-1. The existing rates have
been in effect since July 1, 2022, and the approved rates for FY 2024 will go into effect on July 1,
2023.

4.2 Customer Account Projections
The District’s ratepayers are classified into three customer classes for the purpose of designing its
WW charges. These classes are single family, multi-family, and non-residential. MSD’s WW
revenue reflects the assessment of the specific rate components discussed earlier to each customer
class as applicable. As a result, fluctuations in the number and class of customers served by the
District are a key variable in determining future WW rates.
The historical and projected average numbers of WW customers served by the District are provided
in Figure 4-1 and Table 4-2. As indicated in Table 4-2, the number of total customer accounts
increased by an average of 0.15% per year between FY 2018 and FY 2022. Based on this trend,
the number of customer accounts is projected to increase by 0.24% annually throughout the
forecast.

4.3 Contributed Volumes and Wastewater Flows
Billed WW volume is the estimated amount of water volume contributed to the WW system by
MSD customers. This volume is estimated on either a metered or unmetered basis. The amount of
contributed WW volume from metered customers is measured in Ccf (one hundred (100) cubic
feet, which equates to approximately 748 gallons). The volume from unmetered residential
customers is likewise measured in Ccf as determined based upon estimates of indoor water usage
per fixture and the number of rooms within these properties, referred to as attributes throughout
the Proposal.
Billable WW volumes for all metered residential customers are determined based on water used
during the period best equated to contributed WW volume. MSD defines its best equated period
as a 90-to-92-day period of water usage between December and March of the preceding winter
period. This period most closely reflects the water entering the MSD WW system by avoiding
spring and summer water usage for activities such as lawn sprinkling and the filling of swimming
pools.
Based on previous studies, most recently updated in 2022 1 , billable wastewater volume for
unmetered customers is based on the following attributes:
Attribute Volume Contributions

Rooms 14.5 gpd 12.5 gpd
Water Closet 54.2 gpd 46.7 gpd

The contributed WW volume of all non-residential customers is measured on a metered basis and
billed based on actual usage, less applicable exemption allowances for any water that does not
enter the WW system. Metered multi-family customers are billed based on either actual annual
water usage or the average annual water usage established during the best equated period,
depending on the billing method selected by each multi-family customer. The selected billing basis
is permanent and cannot be changed. Figure 4-2 and Table 4-3 present a summary of historical and
projected billed WW volume.

The projections of contributed volumes are based on the historical trends in billed volumes and
number of customers per customer class. From FY 2018 through FY 2022, the District has
experienced annual reductions in total billed volumes of approximately 1.5%, which is a
cumulative 5.8% reduction. The decrease in billed WW volume is due in part to conservation
measures, increased efficiency of appliances and fixtures, and the impact of the national economy.
Future billable WW volumes are expected to gradually decrease from FY 2022 volumes by an
overall average of 1.8% annually.
4.4 Historical and Projected Wastewater Revenue from Existing Rates
WW revenue under the currently approved rates for the period FY 2023 through FY 2028 is
presented in Table 4-4 on the next page. Estimated revenues for FY 2025 through FY 2028 use
FY 2024-approved rates. The District’s historical WW revenue for FY 2022 is based on actual
rates, customer account and usage data. Projected revenue from WW user charges is based on
projected customer demands and the rates approved through FY 2024 (revenue in FY 2025-FY
2028 assumes no changes in the approved rates for FY 2024). The WW user charge revenue under
existing rates would decrease from $468.2 million in FY 2024 to a projected $454.0 million in FY
2028. This change is due to a combination of key factors: the impact of economic conditions,
projected fluctuations in excess strength WW revenue due to more extensive pre-treatment
programs and projected changes in WW volume consistent with historical trends. As customer
volumes continue to decrease over the projection period, the revenue would be expected to
decrease as well.
WW billing adjustments are determined based on current budget estimates and projected based on
historical trends. These adjustments include late charges, refunds, and other adjustments. The
provision for bad debt has steadily declined over the last several years and is to escalate from FY
2022 budget at the same rate as the base rate and volume rate. This projection is based on predicting
the propensity to pay for all MSD customers with account balances delinquent greater than 30
days.

4.5 Wastewater Operating Expenses
The revenue needed to support the ongoing operation of the District’s WW system must be
sufficient to meet its cash requirements. MSD’s operating revenue requirements consist of the
following:
1. Total WW system O&M expenses
2. Expenditures for routine capital improvements
3. Components of the CIRP funded directly from revenues (i.e., PAYGO)
4. WW revenue bond debt service
5. A minimum 60-day operating reserve
4.5.1 Wastewater Operation and Maintenance Expense
A summary of actual and projected WW O&M for FY 2022 through FY 2028 is presented in Table
4-6. These projections are based on the principal financial assumptions listed below.
1. Customer and Water Usage Growth/Decline
2. Customer Impacts
3. Inflation Rates
4. Bad Debt and Collection Efforts
5. Customer Assistance Program
6. Overhead Rates
7. Basis for cost-of-service indirect/direct cost allocation
8. Average Water/ Wastewater Utility Bill Comparison
9. Salary Projection
10. Wastewater/Stormwater Segmentation
11. Infiltration/Inflow Assumptions
These assumptions have been applied to the District’s O&M from its FY 2023 budget estimates
through the proposed 4-year rate cycle ending in FY 2028. Inflation percentages vary by expense
type. Salary expenses and other related lines are increased annually at 3.65% for the years FY
2025 to FY 2028. Appendix 8.1.1 has a description of the method and calculations used to derive
this factor. Health Insurance expense is projected to increase annually at 5.0 to 8.5%, while general
supplies and contractual services are expected to increase 2.1% annually over the same four-year
period. More detailed information regarding inflation rates is provided in Appendix 8.1.1. Future
WW O&M expense is projected to increase from $185.8 million in FY 2022 to $237.7 in FY 2028.
4.5.2 Wastewater Routine Capital Improvements
Expenditures for routine annual capital improvements include those costs that tend to be routinely
incurred each year for normal replacements such as vehicles, office equipment, and minor
SECTION 4 – PROPOSED WASTEWATER RATES
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
4-13
improvements or repairs (Line 16 of Table 4-10). Since the costs of these improvements are a
continuing expense to be met each year, the District appropriately finances these expenditures from
current WW revenues. These expenses are included in the District’s annual budgets as capital
outlay costs.
4.5.3 Wastewater Capital Projects
Capital projects funded in the O&M budget typically consist of expenditures that do not result in
a new District asset. In general, these projects include infrastructure repairs, watershed planning,
rainfall data gathering, and streamflow sampling, which are all required to maintain existing assets.
The District also funds capital improvements to computer software and hardware out of the O&M
budget. Due to the nature of these projects, they are ineligible for bond or SRF funding; therefore,
they are budgeted as operating expenses.

4.6 Wastewater Major Capital Improvement & Replacement Program
The Capital Improvement and Replacement Program, or CIRP, is the primary cost driver for the
District’s financial plan, representing about three fifths of anticipated expenditures in the FY 2025
to FY 2028 period. In 2012, the District entered into a Consent Decree (CD) with the United States
Environmental Protection Agency and the Missouri Coalition for the Environment for compliance
with the Clean Water Act. The CD requires the District to make investments in the wastewater
system to ensure it has adequate capacity and is properly maintained (Asset Management), to
eliminate sanitary sewer overflows (SSO), to eliminate, reduce, and control combined sewer
overflows (CSO), and to reduce the risk of flooding in the combined sewer area (Cityshed). This
multi-decade CD effort is estimated to cost $7.2 billion (in 2023 dollars), with $2.5 billion
appropriated from FY 2013 through the end of FY 2022. Additional detail is provided in Appendix
8.2.1.
The estimated CIRP needs for the next six years are presented in Figure 4-3 and Table 4-7. The
anticipated CIRP for the next 4-year rate cycle period, FY 2025 through FY 2028, is $1.65 billion.
The largest components of the CIRP over this period will be capital investment related to capacity
improvements in the WW system, and sewage sludge incineration. The CIRP includes
improvements necessary to comply with the CD, with permit and regulatory requirements outside
of the CD, and with asset management renewal at the treatment plants. Additional details are
presented in Appendix 8.2.2.

4.6.1 Wastewater Capital Program Financing
MSD’s CIRP projects are primarily funded by the issuance of senior revenue bonds and SRF loans
with the smaller remaining work funded by the PAYGO revenue stream. Debt financing of the
majority of the CIRP allows the financing burden to be appropriately shared by both present and
future users benefiting from the WW system improvements. Capital improvements routinely
incurred each year as determined by the District’s comprehensive asset management program
(Table 4-7, Lines 1 and 2) are more appropriately financed with PAYGO revenue generated from
annual WW service revenue.
District staff, together with their financial advisor, PFM, has developed a proposed capital
improvement financing plan to fund the CIRP. This plan, presented in Table 4-8, anticipates the
proposed capital improvements will be financed from a combination of WW user charge revenues,
available fund balances, senior revenue bonds, WIFIA loans, Missouri SRF loans, grants and
contributions, and interest income.
Table 4-8 – Capital Improvement and Replacement Program Financing Plan
New senior revenue bonds totaling par value of $507.4 million and $133.1 million in additional
SRF loans are expected to be issued between FY 2025 and FY 2028 to provide this funding. Total
senior revenue bonds, Water Infrastructure Finance and Innovation Act (WIFIA) loans, and SRF
loans are expected to finance approximately 60% of the four-year major capital improvement
program costs, when including the $278 million WIFIA loan in FY 2025. The amount and timing
for each of these issues was developed by the District and affirmed by PFM taking into
FY 2023 FY 2024 FY 2025 FY 2026 FY 2027 FY 2028

consideration the CIRP capital funding needs, current policies, other sources of capital
improvement program financing, and debt service coverage requirements.
The cash financing of capital improvements from annual revenues is expected to total $584 million
between FY 2025 and FY 2028, as indicated on Line 5 of Table 4-8. A portion of the total CIRP
expenditures reflects associated internal labor costs (line 13 in Table 4-7 and line 6 in Table 4-8).
This cost is also expected to be covered by annual PAYGO revenues.
The District anticipates receiving grants and contributions of $3 million between FY 2025 and FY
2028. These sources are expected to fund various improvement projects scheduled to be
constructed during the proposed rate cycle.
Interest earnings are projected to yield an average 1% in annual interest income from FY 2023 to
FY 2028. Line 8 of Table 4-8 provides the estimated interest income earned on all available CIRP
fund balances.
4.6.2 Existing and Projected Wastewater Debt
The District issued its first Districtwide revenue bonds in April 2004. Additional senior revenue
bonds have been issued in 2006, 2008, 2010, 2011, 2012, 2013, 2015, 2016, 2017, 2018, 2019,
2020, 2021, and 2022. The principal remaining on all of the District’s senior revenue bonds issued
to date is approximately $1.32 billion as of June 30, 2022. The District has also participated in
multiple subordinate series of revenue bonds issued under the Missouri SRF loan program. The
total amount of principal remaining on all the District’s SRF Loans issued to date is approximately
$477.8 million as of June 30, 2022, with an additional $125 million issued early in FY 2023. Figure
4-4 shows a projection of the District’s existing and proposed outstanding debt and forecasts of
available bond authorization. The blue line, representing currently available bond authorization,
indicates that the District will not have sufficient authorization to complete the CIRP as proposed
in FY 2025 and would require alternative rates, described in Section 7. The gray line shows bond
authorization each year if the voters were to approve additional authorization of $750 million as
the District intends to request in April 2024.

Figure 4-4 – Outstanding and Projected Debt Principal
The projected amortization of future revenue bond issues has been determined by PFM and is
based on current market conditions and certain assumptions regarding future market conditions.
Generally, future senior revenue bonds are assumed to have a 30-year term and annual coupon rate
of 5.0%. Future SRF loans issued to fund the CIRP program are expected to have 20-year terms
and a net effective annual interest and administration cost of below 3% per year. In addition to the
interest cost of future debt, the District will incur issuance costs with each senior revenue bond
issue, SRF loan, and WIFIA loan. The issuance costs for senior revenue bonds are estimated at
1.0% of the total issuance amount. Issuance costs for SRF loans are expected to be 0.65% of the
total SRF loan amount.
Based on these assumptions, the total annual debt service during the forecast period for existing
debt and future proposed debt is expected to increase from $123.9 million in FY 2022 to $205.6
million in FY 2028 as indicated by Table 4-9.

4.7 Wastewater Operating Reserve
The operating reserve is a balance maintained to accommodate fluctuations in annual revenues and
expenditures. The District has a minimum operating reserve target equal to 60 days of annual
operating expenses. The existing revenue bond covenants require the District to maintain a
minimum balance equal to 45 days of O&M expense. The self-imposed 60 day minimum provides
a buffer to allow for potential timing issues involved with funding requirements, provides
increased operational flexibility, and helps support future bond ratings. The WW operating reserve
is projected to exceed the minimum balance throughout the forecast period. Figure 4-5 presents
the estimated end of year balance in the WW operating reserve throughout the forecast period.

4.8 Summary of Wastewater Revenue and Revenue Requirements
WW revenues must at least be sufficient to finance the WW utility’s O&M expense, routine annual
capital improvements and debt service costs on existing and proposed senior revenue bonds and
SRF loans, while maintaining an adequate operating reserve and complying with all revenue bond
debt service coverage requirements. Annual revenues or existing reserve funds can also be used to
finance the WW utility’s major capital improvement program. Figure 4-6 below presents the
estimated financial plan of the WW enterprise, which shows that annual WW revenues under
existing rates are not sufficient to meet the total revenue requirements of the WW utility during
the forecast period without future revenue increases.

A summary of the financial plan showing projected WW revenues and WW revenue requirements
for the District during the forecast period is presented in Table 4-10. Line 1 of Table 4-10 shows
projected WW user charge revenue that is required in order to balance the revenue and the revenue
requirements through FY 2028. The magnitude of the increase shown for each year was selected
based on consideration of three principal criteria:
(1) Total revenue necessary to meet cash requirements for normal WW operations. This
includes consideration of a one-month lag in the receipt of additional user charge revenue
from increased rates,
(2) Annual increases in WW revenues available to cash finance a portion of the WW utility
related major capital improvements, and
(3) WW revenue required to meet certain financial metrics, based on comments from the
District’s rating agencies, including debt service coverage levels and strong liquidity
position over the Rate Proposal period.

In addition to the WW revenue generated from WW user charges, other revenue identified in line
2 of Table 4-10 includes other operating revenue, interest earnings, and connection fee revenue
(previously presented on Table 4-5). Total revenue is projected to be $467.0 million in FY 2023
and increase to $608.6 million in FY 2028, as shown by line 3 of Table 4-10.
The WW utility’s O&M expenses, previously introduced in Table 4-6, are shown on line 6 of Table
4-10. Line 24 of Table 4-10 shows the estimated net revenue remaining after deducting WW O&M
expenses from total WW revenues (line 3 minus line 6, plus interest income from Table 4-8, Line
8). Anticipated debt service requirements on senior revenue bonds and SRF and direct loans are
presented on lines 7 through 13, as presented previously on Table 4-9. These projected debt
obligations will require the District to obtain additional revenue bond authorization in the amount
of $750 million before the start of FY 2025. Sewer service charge revenue used to finance a portion
of the major capital improvement program are reported as a cost on line 14. Line 15 shows the
non-recurring projects and studies, which are completely financed by annual revenues.
The total annual surplus or deficit is presented in line 20. Positive balances indicate a projected
increase in the operating reserves, while negative balances indicate the need to draw down
available fund balances. The beginning and ending balance of the operating reserve is shown on
lines 21 and 22.
An additional consideration in measuring the adequacy of revenues is the provision of sufficient
debt service coverage to meet the actual debt service paid to the bondholders on the senior revenue
bonds and on the SRF loans as previously presented in Table 4-9. Line 26 shows the debt service
coverage of the senior revenue bond debt service, i.e., the ratio of net revenue (line 24) to total
senior revenue bond debt service (line 25) for each year of the study period. Line 28 shows the
debt service coverage of the combined senior revenue bond and SRF debt service, i.e., the ratio of
net revenue (line 24) to total debt service (line 27) for each year of the study period. Current WW
revenue bond covenants require the District to provide debt service coverage equal to at least 125%
(>1.25x) of the annual principal and interest payment on all senior revenue bonds and 115%
(>1.15x) of the combined annual principal and interest payment on all WW senior revenue bonds
and all SRF loans.
Further, the rating agencies have all noted that the District’s current credit rating could be
compromised if projected debt service coverage narrowed or fell below targeted levels. The Rate
Proposal is designed to maintain a senior debt service coverage ratio of at least 2.5x and a total
debt coverage ratio of at least 1.8x over the Rate Proposal period.
4.9 Cost-of-Service Analysis
The basic principle in the establishment of cost-of-service rates is to achieve general fairness in
the recovery of costs from various classes of customers. The approach used in this Rate Proposal
SECTION 4 – PROPOSED WASTEWATER RATES
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
4-26
is based on the principles endorsed by the Water Environment Federation (WEF), which allows
the District to demonstrate rates have not been set in an arbitrary manner and one class of customer
is not subsidizing another to an unjustifiable extent, or in a manner that is not approved and
supported by the District.
It is common for utilities to use a test year when performing a cost-of-service study. FY 2025 is
being used as the cost-of-service test year for all subsequent tables presented in this report. Test
year refers to the year used to design rates. For FY 2026 through FY 2028, across-the-board rate
increases have been applied to all charges with the understanding that the test year is representative
of operating conditions for the next few years.
The cost-of-service process begins with the total District expenditures for the test year. WW
system costs have been allocated between customer classes based on their estimated demand
requirements and recognizing the different costs associated with serving different customer
classes. Factors considered in determining service requirements include the volume of WW
contributed, peak WW contributions, WW strength, number of accounts and the relative
responsibility for infiltration/inflow entering the WW sewer system. Figure 4-7 presents a
schematic of the general steps involved in a cost-of-service process.
As seen in Figure 4-7, the cost-of-service process takes the total District costs and allocates those
costs between WW and SW services. The allocation of WW costs to functions and customer
classes is discussed in greater detail in the remainder of Section 4.

4.9.1 Cost Allocations
As mentioned previously, the test year for performing the cost-of-service analysis is FY 2025.
Revenue requirements identified as part of the Rate Proposal were used as the basis for the cost-
of-service allocations and were shown in Table 4-10. The cost-of-service methodology
necessitated that the revenue requirements be allocated into functional categories presented in
Figure 4-7. The revenue requirements were allocated to the functional categories based on
allocation factors developed by District staff using available data, and generally accepted industry
practices, and were then reviewed to ensure the appropriate allocation factors were applied. For
example, operating costs for the customer service center were allocated to customer service and
billing; costs for operating the treatment plants were allocated to treatment; and collection costs
were allocated between collection and conveyance. General and administrative cost elements are
allocated based on the weighted average allocation of the direct costs.
Capital costs (debt service requirements and rate-funded capital) were allocated based on the
allocation of the District’s fixed assets and not on the allocation of specific debt issuances. The
estimated test year FY 2025 plant investment consists of assets in service as of June 30, 2022, and
the estimated costs of proposed capital improvements to be placed in service through the FY 2025
test year. Total plant investment, on an original cost less accumulated depreciation basis, was
allocated to functional cost components. For example, the investment in the sanitary sewer system,
consisting of mains and pumping stations, is related to maximum rates of flow and is allocated to
the capacity cost component. Test year plant investment in WW facilities on an original cost less
depreciation value basis is projected to total $2.89 billion in FY 2025. The allocation of total plant
investment is used as the basis to allocate total routine capital improvements, cash-financed capital,
and annual debt service requirements.
The test year cost of service to be recovered by the District is equal to $499.4 million with
operating expenses equal to $209.1 million and capital costs equal to $290.3 million, as shown in
Table 4-11, which presents the allocation of total District costs and revenue offsets into operating
and capital components. For the test year FY 2025, approximately 42% of total annual revenue
needs are related to operating expenses and the remaining 58% is due to capital expenditures.

The allocations of these costs to each functional category are also shown in Table 4-12. These
costs are offset by miscellaneous revenue sources to arrive at the net functional category costs that
are used to develop unit costs of service. The detailed allocations and calculations performed can
be followed in the electronic rate model.

Table 4-12 – Cost Functionalization Summary
4.9.2 Cost Classification
The functionalized costs are next allocated to their cost components in accordance with how the
facilities are designed. In this step of the cost-of-service process, costs are apportioned to the
functional cost drivers of volume, capacity, compliance, WW strength, and customer and billing.
The separation of costs into functional cost components provides a means for distributing such
costs to the various cost drivers on the basis of respective responsibilities for each particular type
of service. The following are the principal functional cost components:
- Volume Costs are those which vary directly with the quantity of WW contributed and
include capital costs related to investment in system facilities sized on the basis of WW
volume and O&M expense related to those facilities.
- Capacity Costs are related to facilities that are designed to meet the maximum or peak
rates of WW flow.
- Compliance Costs are those incurred running the commercial monitoring and
compliance program.
- Customer & Billing Costs are related to the costs of customer service functions, such
as billing and support, collections, etc.
- WW Strength Costs (TSS/BOD/COD) consist of the O&M and capital costs related to
system facilities that are designed principally on the basis of the quantity of pollutants
in the WW. Strength costs are further separated into biochemical oxygen demand

chemical oxygen demand (COD) at the treatment plant and for certain high strength
customers. Since historical data have consistently indicated a stable relationship
between BOD and COD loadings, the COD and BOD surcharge units of service are
combined as equivalent BOD units and presented as a single functional cost
component.
Other operating and non-operating revenues are used to offset the allocated costs of service and

4.9.4 Development of Customer Class Units of Service
The total cost responsibility for each customer class is determined by developing WW system unit
costs of service for each cost component and applying these unit costs to the respective service
requirements of each customer class. In accomplishing this, each customer class is allocated a
share of volume, capacity, strength and customer costs for which it is responsible.
Customers are divided into customer classes that represent a particular type of service requirement
or load on the system. The residential customer class includes residents living in single family and
multi-family dwellings. The non-residential class includes all customers not included in the
residential class such as commercial, government, industrial etc. WW strengths exceeding the
normal WW strength thresholds, which are contributed by a portion of the non-residential class,
are segregated into a separate surcharge customer group.
The determination of customer class responsibility for costs of service requires that the customer
classes be allocated a portion of the volume, capacity, strength and customer costs of service
according to their respective service requirements. Service requirements or units of service for the
respective customer classes are developed in Table 4-14 for FY 2025. Annual contributed WW
volume and number of bills are based on the projected number of WW customers served by the
District according to the growth assumptions identified in Section 4.2.
As previously discussed, billable WW volume for unmetered residential customers is based on
water usage as determined by indoor water usage attributes. Billable WW volume for metered
residential customers is based on water usage as measured during the best equated period, and
billable WW volume for all non-residential customers is based on measured water usage less
exemption allowances for water not contributed to the sewer system.
Infiltration/inflow (I/I) includes flow entering the sewer system from illegal roof and foundation
drains, groundwater infiltration through sewer service pipe and main joints and SW runoff or
inflow from the combined sewer system. Based on an analysis of five years of data from the
District’s wastewater treatment plants and billing system, Districtwide I/I is approximately 62%
of the total WW flow.
Each customer class should bear its proportionate share of the costs associated with I/I, as the WW
system must be adequate to convey and process the total WW flow. The amount of I/I to be
recovered directly from WW service charges is assigned to customer classes on the premise that
40% of the total is distributed based on the number of customers within each class, with the
remaining 60% allocated based on contributed WW volume. These percentages are based on
independent engineering studies completed in October 2022 by Stantec and presented in Exhibit
SECTION 4 – PROPOSED WASTEWATER RATES
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
4-33
MSD 66. There are no known changes in the system that would significantly change this
assumption.
The responsibility for collection system capacity related costs varies with the peak flow of both
contributed WW and I/I attributable to each customer class. Contributed flows are estimated to
have a peak to average flow ratio of 1.16 times, while the I/I is estimated to have a peak to average
flow ratio of 5.14 times the average flow for I/I.
The BOD and TSS responsibility of each customer class is based on average strength
concentrations and contributed WW volume for each class. Recent operational statistics for the
existing WW treatment plants indicate that the 5-year average influent strength of WW is 106
milligrams per liter (mg/l) for BOD and 160 mg/l for suspended solids. Deducting allowances for
I/I and excess strength units subject to surcharge from the total WW strength units, results in an
average contributed WW strength of approximately 265 mg/l for BOD and 285 mg/l for suspended
solids. Average contributed WW strengths are estimated to be the same for all customer classes
recognizing that the type of residential and non-residential development in the District suggests
that differences in average WW strengths among the classes are not likely to be significant.
Customer billing and collection costs are distributed to customer classes on the basis of the number
of bills for each customer class. Environmental compliance costs are based on a five-tier system
to recover costs more equitably from non-residential customers. To allocate costs for this proposed
rate structure, non-residential customers must be expressed in terms of equivalent bills. Equivalent
bills are used to equate relative cost responsibility of higher tier customers to those of Tier 1
customers. For example, one Tier 5 customer pays the equivalent compliance charge of 67 Tier 1
customers. The units of service are presented in Table 4-14.
Table 4-14 – Wastewater Units of Service
4.9.5 Distribution of Costs to Customer Classes
The costs of service to be recovered from WW charges include net O&M costs and total net capital

of the unit costs of service to respective service requirements as shown in Table 4-15. Unit costs
of service for each functional cost component are based on the total cost divided by the total
applicable units of service. Applying these common unit costs of service to the respective service
requirements of each customer class determines the total allocated cost of service for each class.
Table 4-15 – Development of Wastewater Unit Costs of Service
After identifying the unit costs of service for each of the system functions, the costs are allocated
to specific customer classes based on the proportionate demand each places on the system. The
development of costs allocable to each customer class is presented in Table 4-16. After allocating
costs to each class, the I/I costs have been redistributed to each customer class based on the
proportional share of the system (both on an account and volumetric basis).

Once the costs have been allocated to each customer class, the allocated costs are compared to the
level of revenue recovery under the approved rates for FY 2024 to determine the magnitude of
indicated revenue increases for each customer class that provides equitable and sufficient revenue
recovery. The comparison presented in Table 4-17 shows that an overall revenue increase of 7.5%
is needed to meet the revenue requirements in FY 2025. These increases are projected with slight
variations to each customer class based on the cost-of-service results. The specific rates
recommended to meet the cost-of-service results are presented in section 4.10.2.
Table 4-17 Comparison of Existing Revenue to Wastewater Cost of Service
4.10 Wastewater Rate Adjustments
The principal consideration in designing WW rate schedules is to establish charges to customers
that are reasonably commensurate with the cost of providing WW service. Theoretically, the only
method of assessing entirely equitable charges for WW service would be determination of each
customer’s bill based upon the customer’s particular service requirements. Since this is impractical
for the thousands of customers served by the District, schedules of rates are normally designed to
meet average conditions for groups of customers having similar service requirements. Practicality
also requires that rates be reasonably simple to apply, recover costs proportionately from all classes
and be subject to as few misinterpretations as possible.
4.10.1 Existing Wastewater Rates
The FY 2023 schedule of rates for WW service shown in Table 4-1 became effective on July 1,
2022. The rates consist of base service charges, a variable volume charge, and extra strength
surcharges for BOD in excess of 300 mg/l or COD in excess of 600 mg/l and suspended solids in
excess of 300 mg/l. The base service charges include a billing and collection component and a
system availability component that are applicable to all customer classes and a tiered compliance
charge that is applicable only to non-residential customers. The variable volume charge is
determined by a rate ($/Ccf) multiplied by the amount of each customer’s water usage. The same

rate is used for all customers, but water usage is determined depending on whether the customer
is metered or unmetered. For metered customers, water usage is measured in Ccf and the charge
is expressed on a per Ccf basis. For unmetered customers, water usage is determined by each
customer’s attributes (as converted to Ccf) and the charge is expressed on a per attribute basis.
4.10.2 Impact on Customer Classes with Proposed Wastewater Rates
The proposed WW rates presented in Table 4-18 were developed using a rate model and are based
on cost of service and policy considerations. These rates are assumed to be effective on July 1,
2024 (upon commencement of the District’s FY 2025). Table 4-18 shows a comparison between
existing FY 2023 rates, rates approved for FY 2024, rates proposed for test year FY 2025, and
WW rates proposed for FY 2026 through FY 2028.

4.10.3 Customer Assistance Charges
The District provides a 50% discount on WW service charges for low-income residential
customers participating in the MSD Customer Assistance Program (CAP) based on established
District policy. The current customer participation is approximately 4,200 customer accounts or
1% of the District’s total number of single family and multi-family (up to 6 units) ratepayers.
Figure 4-8 shows the historical 5-year trend in the program, and the program guidelines are
presented in Table 4-19.

Table 4-19 – CAP Poverty Guidelines
The first CAP rate was adopted by the Board of Trustees in 1993 by Ordinance 9031. Since that
time numerous changes have been made to the program to remain current with the changing
demographics of MSD ratepayers. Current policy defines CAP eligibility as residential customers
with household income for the previous year less than 200% of the most recent Health and Human
Services (HHS) poverty guidelines by household size and less than 250% for disabled individuals
or those ages 62 or older. Table 4-19 shows household income limits by family size used to check
a customer’s eligibility to participate in the CAP as of the date of this report. The District’s
eligibility criteria include Multi-Family residential customers residing in Multi-Family housing
consisting of six units or less. In November 2014 the MSD Board approved a one-time 50%
reduction in any outstanding service charges for those accepted into the program. These changes
were made to assist the District’s continuing efforts to increase the number of customers
participating in the program. Considerable focused outreach efforts are also a significant
component of promoting the CAP. Examples of these efforts can be found in Appendix 8.6.
The cost impact of the District’s current CAP program on a typical single family residential
customer not eligible for assistance and discharging 5 Ccf per month of WW is expected to be
about $0.23, or 0.37% per month of the District’s FY 2025 WW service charge revenue.
4.10.4 Excess Strength Wastewater Surcharges
The proposed WW volume charges shown in Table 4-18 are designed to recover costs for volume
associated with normal strength contributed WW. To provide for the recovery of costs associated
with above average strength contributions, an extra strength surcharge rate is applied to WW

loadings that exceed normal strength limits of 300 mg/l for suspended solids and 300 mg/l for
BOD or 600 mg/l for COD. Cost-of-service based rates for excess strength WW are equal to the
unit costs shown on line 6 of Table 4-15 and are expressed on a cost per ton basis.
The cost-of-service analysis indicates a significant increase in the surcharge rates for BOD, COD,
and TSS. This increase is caused by several factors, most significantly that the capital cost
allocated to these functional categories increased substantially due to the District’s fluidized bed
incinerator (FBI) projects used to dispose of solids as part of the treatment process. Additionally,
units of service for extra strength BOD and COD decreased by 15% and TSS decreased by 13%
from FY 2018 through FY 2022. These factors result in an increase in rates that is larger than other
rate components.
4.10.5 Compliance Charge
Costs incurred by the District to monitor the quality of WW volume from non-residential
customers is recovered by a 5-tier structure of compliance charges. This tiered system allocates
costs to customers in proportion to the number of inspections and sophistication of monitoring
required. The total cost to monitor customers in this regulatory required compliance program is
based on estimates by District environmental compliance program staff.
Tier 1 – Non-Residential Customers Not Subject to Inspections with no Sample
Point.
Tier 2 – Non-Residential Customers Subject to Inspections with No Sample Point
Tier 3 – Non-Residential Customers Subject to Inspections with One Sample
Point
Tier 4 – Non-Residential Customers Subject to Inspections with Two Sample
Points.
Tier 5 – Non-Residential Customers Subject to Inspections with Three or More
Sample Points
95% of the District’s non-residential customers are classified as Tier 1. For rate design purposes,
customers in the other 4 tiers are based on an equivalent basis with Tier 1 customers by dividing
their respective unit costs by the unit cost indicated for Tier 1 customers. Multiplying these cost
ratios by the Tier 1 rate derives the proposed compliance rates shown in lines 4-8 of Table 4-18.
Tier 1 non-residential customers currently pay $4.71 per month, and the approved charge for FY
2024 is $4.85 per month. Under the Proposed rates this charge increases to $7.44 per month in FY
2025.

4.10.6 Wastewater Revenue under Proposed Rates
A comparison of allocated cost-of-service results for FY 2025 with WW revenue under the existing
rates is shown in Table 4-17. As indicated, revenues under the previously approved rates are
inadequate to meet the total revenue requirements. The recommended rates presented in Table
4-18 adequately recover the total cost of service, and equitably recover the allocated cost of service
from each customer class. The allocation of these costs was adjusted to reflect current volume and
costs. The District has not changed its rate structure in determining this re-allocation. In addition
to the recovery of cost of service, the proposed rates have been designed to support the financial
requirements of the system as identified throughout this Section. Table 4-20 presents a comparison
under the recommended rates to the allocated costs of service.
Table 4-20 – Comparison of Revenue under Proposed Rates to Cost of Service
4.11 Proposed Wastewater Rate Change Meets MSD Charter Criteria
The MSD Charter Plan, Section 7.270, requires that any change in a Rate recommended to the
Board by the Rate Commission be accompanied by a statement of the Rate Commission that the
proposed Rate change and all portions thereof meet five criteria. The following is a list of each
criterion and an explanation of how each has been met by the current Rate Proposal.
1. Is the Rate change consistent with constitutional, statutory or common law as
amended from time to time?
Yes. The wastewater user charge is consistent with the District’s Charter.
Under Section 3.020(16), the District may “establish by ordinance a schedule or schedules
of rates, rentals, and other charges, to be collected from all the real property served by the
sewer facilities of the District, whether public or private, and to prescribe the manner in
which and time at which such rates, rentals, and charges are to be paid, and to change such
schedule or schedules from time to time as the Board may deem necessary, proper, or
advisable, and to collect or enforce collection of all such charges.” Therefore, the Proposed

SECTION 4 – PROPOSED WASTEWATER RATES

Wastewater Rate Change complies with the rate change procedures set forth in Charter
Section 7.280.
In addition, in Missouri Growth Association v. Metropolitan St. Louis Sewer District, 941
S.W.2d 615 (Mo. App. E.D. 1997), the Missouri Court of Appeals held that the District’s
wastewater service charges were user fees, not taxes, and therefore rate increases did not
require voter approval pursuant to Article X, Section 22(a) of the Missouri Constitution
(the Hancock Amendment).
The structure of the wastewater charge contained in the Proposed Wastewater Rate Change
is the same as that approved in the Missouri Growth decision.
2. Does the Rate change enhance the District’s ability to provide adequate sewer and
drainage systems and facilities, or related services?
Yes. The Proposed Rate Change will provide the funding necessary to allow the District
to operate and maintain its systems and make necessary capital improvements to meet the
commitments of the Consent Decree and comply with existing permit regulations. In
addition, it provides the funds needed to continue adequate O&M in the collection systems,
pump stations, and wastewater treatment plants. The CMOM program should continue to
improve the operations of the collection system and reduce overflows and basement
backups.
3. Is the Rate change consistent with and not in violation of any covenant or provision
relating to any outstanding bonds or indebtedness of the District?
Yes. The Proposed Wastewater Rate Change is consistent with all outstanding bonds and
indebtedness and will not cause the District to violate any provisions or covenants related
to said bonds or indebtedness. Examples of provisions and covenants are requirements to
provide revenue to cover O&M expenses, to provide reasonable Revenue Fund reserves,
to produce Net Operating Revenues sufficient to meet minimum Debt Service
Requirements, and to make all required payments into Debt Service Reserve Accounts.
4. Does the Rate change impair the ability of the District to comply with applicable
Federal or State laws or regulations as amended from time to time?
No. The Proposed Wastewater Rate Change is necessary to provide the District with the
funds necessary to address the aging wastewater system and resulting wet weather impact.
The District is subject to an array of Federal and State environmental laws concerning such
things as discharge and effluent levels, each of which carry with them the imposition of
SECTION 4 – PROPOSED WASTEWATER RATES
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
4-42
financial fines of various amounts. Administration of the Federal Clean Water Act has
been delegated to the Missouri Department of Natural Resources (MDNR) by the U.S.
Environmental Protection Agency (EPA). The District is regulated by the MDNR to ensure
compliance with the requirements established under the Clean Water Act. The Clean
Water Act provides for statutory penalties up to $50,000 per violation per day. Failure to
meet the requirements imposed at the Federal and State level would be extremely
burdensome financially and could directly hamper or even thwart the efforts of the District.
In addition, Section XI of the Consent Decree outlines stipulated penalties for which MSD
may be liable if the District does not comply with the Consent Decree. These penalties
range from $500 to $4,000 per day depending upon the type and length of noncompliance.
Therefore, the Proposed Wastewater Rate Change is necessary to meet legal requirements
imposed upon the District. Failure to construct mandated projects or properly maintain
existing lines and facilities will expose the District to the possibility of immediate and
direct legal and financial consequences.
5. Does the Rate change consider the financial impact on all classes of ratepayers in
determining a fair and reasonable burden?
Yes. The District’s cost of service analysis (see Table 4-20) reflects that the proposed rate
adjustments by customer class closely aligns with the cost to provide wastewater services
to each customer class. In addition, the District commissioned a study of the contributed
water volumes associated with various attributes of unmetered property (see MSD Exhibit
65). This study was used to ensure that the rate revenues received from these customers
aligned with the cost to provide wastewater service. Also, the Rate Change Proposal (see
Appendix 8.6) continues to provide funding for the District’s Customer Assistance
Program (CAP). CAP eligibility is based on income and household size and provides a
50% discount of the current charges for wastewater services.
SECTION 5 – PROPOSED STORMWATER Capital FUNDING
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
5-1
PROPOSED STORMWATER FUNDING
MSD submits this Stormwater Capital Proposal to fund projects to address flooding and erosion
control, consisting of an ad valorem property tax on residential customers and an impervious area-
based rate for non-residential customers (sometimes collectively the “SW capital charges”).
5.1 Stormwater Revenue Requirements
The revenue required to provide for the continued operations of the District’s SW utility must be
sufficient to meet its cash requirements for system operation. Revenue requirements include (1)
regulatory expenses; (2) total SW system O&M expenses; (3) expenditures for capital
improvements, particularly deferred capital; and (4) provision for an adequate operating reserve.
5.1.1 Stormwater Regulatory Services
MSD has certain regulatory obligations it must comply with to meet SW quality requirements
outlined by federal and state statutes and regulations. The District is the lead co-permittee in an
MS4 permit for the St. Louis region. Under this permit, MSD must implement Best Management
Practices (BMP) to address SW quality issues. MSD is required to have a public education and
outreach program, an illicit discharge detection and elimination program, and a SW pollution
prevention program. MSD and the co-permittees are also required to regulate and enforce the
construction and continued maintenance of water quality features (Stormwater BMP) to control
pollutants in SW runoff from development projects both during and after construction is complete.
The 2 cent SW regulatory property tax levied by the District provides adequate funding to meet
MSD’s current regulatory obligations. Whether or not this Rate Proposal is implemented, this tax
will remain in place to fund these services.
5.1.2 Stormwater Operation and Maintenance Expense
Revenue collected from the existing 10 cent stormwater O&M property tax is available to fund
SW related O&M expenditures. These activities include removing blockages, open channel
cleaning, repair of storm sewer line failures, and limited inlet inspections and cleanings.
The FY 2023 adopted budget is the basis for projecting the majority of existing SW O&M expenses
and is adjusted for the same inflation and growth factors as other MSD O&M expenses. Table 5-
1 shows FY 2023 SW expenditures to be $44.2 million. The policy for how the SW utility is
operated and maintained is contained in Exhibit MSD 64.

Table 5-1 – Stormwater Expenditures
5.1.3 Stormwater Capital Improvement Program
The SW CIRP outlined in this proposal is comprised of three major categories. The proposed SW
capital charges would fund an average of approximately $35 million of capital expenditures
annually to address flooding and erosion. The two remaining categories are paid for with existing
fund balances in OMCI funds and a small percentage of the O&M tax revenue. These two
categories represent approximately $49 million of the projects identified in this Rate Change
Proposal. However, once the OMCI funds’ balances are fully depleted and the projects identified
to be funded from the O&M tax revenue are completed, no funding source will be available for
SW CIRP without approval of the proposed SW capital charges.

Figure 5.1 – Stormwater CIRP Needs
5.1.4 Operating Reserve
The SW operating reserve is necessary to provide protection for unplanned expenses. Under the
existing funding mechanism, SW revenues are collected from ad valorem taxes which are collected
annually in the City and County. Due to this annual revenue collection schedule, it is necessary for
the SW fund to maintain a reserve balance that provides sufficient working capital to meet the
regular operating expenses in the first six months of a fiscal year after which a new year’s revenues
will be collected. The District targets an operating reserve equal to 240 days of SW O&M expense
in the existing Regulatory and Districtwide O&M Stormwater funds. The existing OMCI funds
do not have a minimum reserve requirement as it is intended to completely spend those funds down
as projects in each OMCI area are undertaken. The proposed SW capital rate fund does not have
a fund balance requirement because it will be used to fund capital projects as funds are available.

5.2 Existing Stormwater Funding Methods
The District currently has three existing funds for SW related activities: the OMCI Funds,
Regulatory Fund, and O&M Funds.
5.2.1 OMCI Funds
The OMCI Funds’ ad valorem taxes are collected from specific service areas within the District to
fund projects within those specific service areas. After voters approved the Districtwide O&M
property tax in 2016, these OMCI tax rates were all set to zero, though subsequently taxes have
been collected in seven districts at the request of the communities they serve. Table 5-2 shows
recent and projected revenues and expenditures from these funds.
Table 5-2 –OMCI Funds
5.2.2 Regulatory Fund (2 cent property tax)
The Regulatory Fund is funded by the 2 cent SW regulatory property tax. This fund is intended to
fund regulatory activities related to SW throughout the District’s service area and is collected from
all properties within the District’s service area. Table 5-3 shows recent and projected revenues and
expenditures from this fund.

Table 5-3 –Regulatory Fund
5.2.3 Districtwide Stormwater Fund for O&M (10 cent property tax)
The Districtwide Stormwater Fund for O&M is currently funded by the 10-cent tax approved under
Proposition S in April 2016. The current tax levy is assessed to most properties within the service
area; however, those properties within certain levee districts are excluded because those levee
districts provide the SW services that would otherwise be paid for by this fund (see section 5.4 for
additional information). Table 5-4 shows recent and projected revenues and expenditures from
this fund.

5.3 Proposed SW Capital Funding
This Stormwater Capital Proposal supports implementing a stormwater capital funding program if
approved by the voters of the District. This program would be used to fund capital improvements
primarily to address flooding and erosion control in the SW system.
The Stormwater Capital Proposal consists of two funding mechanisms. First, for residential
customers, stormwater capital funds will be recovered using an ad valorem property tax of 7.45
cents per $100 assessed valuation. This tax rate was determined based on feedback from the
community about the level at which they would be willing to support a stormwater capital program.
Second, for non-residential customers, stormwater capital funds will be recovered using a rate
based on the amount of each property’s impervious area.
The proposed non-residential impervious rate was developed to correspond to the residential
property tax rate based on the following considerations. First, the proportion of revenue to be
collected from non-residential customers was determined based on the ratio of total impervious
area of non-residential customers divided by the total impervious area of residential customers
(43%/57%). Then, the amount of revenue generated by the residential customers (approximately
$19.3 million/year) was then multiplied by this ratio to determine the revenue to be collected from
the non-residential customers (approximately $14.8 million/year). The proposed impervious area
rate of $1.05 per 1,000 square feet was determined based on the proposed non-residential capital
improvement program revenue ($14.8 million) divided by the estimated units of non-residential
impervious area in the District’s service area. Impervious area will be measured, and customers
will be charged based on units of 1,000 square feet.
The proposed capital improvements to be funded by this Stormwater Capital Proposal will address
local flooding, regional flooding, and erosion within the District.
Table 5-5 shows projected revenues and expenditures from this fund.

Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
5-7
Table 5-5 –Proposed SW Capital Fund
5.4 Levee Districts
The rate proposal recommends that Levee Districts currently under agreements with MSD 2 be
exempt from the proposed SW capital charges. The Levee Districts possess, pursuant to statutory
authority, the responsibility to provide stormwater services within their respective service areas,
including capital improvements to address flooding and erosion. Accordingly, MSD will not
charge the SW capital charges within the Levee Districts. With that, as was previously agreed to,
MSD and the Levee Districts will continue agreements (See Exhibit MSD 62 for Levee District
Agreements) that outline these responsibilities. The current agreements require MSD to provide
only certain regulatory services within the Levee Districts. Revenues to cover this regulatory
expense will be from the continuation of the regulatory tax currently assessed throughout the MSD
service area, including the Levee Districts.
5.5 Proposed Stormwater Rate Change Meets MSD Charter Criteria
The MSD Charter Plan, Section 7.270, requires that any change in a Rate recommended to the
Board by the Rate Commission be accompanied by a statement of the Rate Commission that the
proposed Rate change and all portions thereof meet five criteria. The following is a list of each
criterion and an explanation on how each has been met by the current Rate Proposal.
1. Is the Rate change consistent with constitutional, statutory or common law as
amended from time to time?
Yes. The Stormwater Capital Proposal is consistent with the District’s Charter.
2 All levee districts in MSD’s service area except Missouri Bottoms-Hazelwood Levee District have entered into an
agreement with the District. Customers in the Missouri Bottoms-Hazelwood Levee District pay the 10 cent O&M tax
and would pay the proposed stormwater capital charges.
SECTION 5 – PROPOSED STORMWATER Capital FUNDING
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
5-8
The proposed impervious area-based charge on nonresidential customers is consistent with
MSD Charter Plan Section 3.020(16), which states the District may “establish by ordinance
a schedule or schedules of rates, rentals, and other charges, to be collected from all the real
property served by the sewer facilities of the District, whether public or private.”
The proposed ad valorem property tax on residential customers is consistent with MSD
Charter Plan Section 3.020(20), which states the District may “levy, assess, and collect
taxes on all taxable property within the District....”
The Stormwater Capital Proposal is also consistent with the Missouri Constitution.
Article X, § 22(a) of the Missouri Constitution (the Hancock Amendment) prohibits a
political subdivision of Missouri from “levying any [new] tax, license, or fee, …without
the approval of the required majority of the qualified voters of that … political
subdivision voting thereon.” The Stormwater Capital Proposal will be taken to the voters
for approval.
2. Does the Rate change enhance the District’s ability to provide adequate sewer and
drainage systems and facilities, or related services?
Yes. MSD currently has sufficient revenue sources to provide only Stormwater Regulatory
Services and Stormwater O&M Services throughout the entire District. However, under
the District’s Charter, MSD is empowered also to provide the flooding and erosion type of
services being proposed. The District has regularly surveyed its customers and other
stakeholders to determine whether they would like another opportunity to vote on a
proposition like the current Stormwater Capital Proposal. As a result of public requests
regarding flooding and erosion issues as well as other public input, we have concluded that
our customers should have the opportunity to vote on whether MSD should collect revenue
to provide this additional service.
3. Is the Rate change consistent with and not in violation of any covenant or provision
relating to any outstanding bonds or indebtedness of the District?
Yes. This Rate Proposal will not have any impact on the District’s outstanding debt
because stormwater revenue is not pledged for repayment of the District’s outstanding
debt.
4. Does the Rate change impair the ability of the District to comply with applicable
Federal or State laws or regulations as amended from time to time?
SECTION 5 – PROPOSED STORMWATER Capital FUNDING
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
5-9
No. The Stormwater Capital Proposal does not address any particular federal or state law
or regulation. The Stormwater Capital Proposal is based upon MSD customers’ needs and
wants to address flooding and erosion in our region.
5. Does the Rate change consider the financial impact on all classes of ratepayers in
determining a fair and reasonable burden?
Yes. A review of how the Stormwater Capital Proposal was developed will demonstrate
that the financial impact on all classes of rate payers was considered in determining a fair
and reasonable burden. First, an ad valorem property tax rate of 7.45 cent per hundred
dollars assessed valuation was determined to be the maximum amount that the residential
customers would reasonably support for stormwater capital projects. This will generate
approximately $19.3 million per year in revenue. Customers supported the use of ad
valorem property taxes to pay for stormwater O&M services at the April 2016 Stormwater
O&M election, and they have historically paid for MSD stormwater services through ad
valorem property taxes. In addition, the use of property valuation in determining the share
of revenue to be provided by each individual residential customer will allow those who
reside in lower valued properties to have a smaller annual payment.
Second, the corresponding amount of revenue to be provided by the non-residential
customers was determined by comparing the ratio of impervious area attributable to the
residential customer class versus the impervious area attributable to the non-residential
customers. This calculation shows that approximately $14.8 million per year should be
provided by non-residential customers. This revenue will be collected at a rate of $1.05 per
month for every thousand square feet of impervious area for our non-residential customers.
To provide a fair burden for this set of customers, these charged customers shall include
all non-residential customers even if they are tax exempt. The use of an impervious area-
based rate only for non-residential customers will also significantly reduce the annual cost
of the stormwater revenue collection process.
Finally, the program expenditure goals will address the requirements of this factor. The
program will consist of a goal of spending 50% of the revenues on stormwater capital
projects Districtwide on a prioritized basis using MSD’s cost/benefit analysis, a goal of
providing 30% of the revenues to the municipalities and county in our service area (share
to be determined by population) in the form of grants to allow for prioritization of any
stormwater project by the individual entities, a goal of spending 10% of the revenues on
stormwater capital projects within Environmental Justice areas using MSD’s cost/benefit
analysis, and finally a goal of spending 10% of the revenues on projects identified by MSD

OVERALL CUSTOMER IMPACTS
The District must generate annual revenues that are sufficient to meet the current operating, capital,
and financial policy requirements to support the WW and SW service levels. Sections 4 and 5
identified the individual Rate Proposals for WW rates and SW capital charges that are sufficient
to meet the District’s needs. District customers will be asked to support the utilities and it is
important to understand the potential impacts to District customers from the WW and SW utilities.
6.1 Typical Wastewater and Stormwater Bills by Customer Class
Table 6-1 presents a comparison of typical WW service bills under existing rates, rates currently
approved through FY 2024, and under the proposed FY 2025 through FY 2028 rates, for various
billable WW volumes and customer classes. As indicated by this table, the monthly bill for a
typical single family residential customer contributing 5 Ccf 3 of WW each month to the
wastewater system is projected to increase by $18.19 from FY 2024 to FY 2028.
3 5 Ccf typical bill is based on the latest available billing data. The residential average bill at the time of the 2019 Rate
Proposal was 6 Ccf per month.

Table 6-1 Typical Wastewater Bills
Billable WW volumes for unmetered customers are derived from volumes attributed to household
attributes. Based on a prior study of unmetered customers, the most common or “typical”
unmetered customer was one with five rooms, one water closet and one bath. The volume
associated with a customer with these housing attributes is approximately 6 Ccf. Table 6-2 presents
sample unmetered bill impacts. The WW bill for a typical unmetered residential customer would
increase by $15.22 from FY 2024 to FY 2028.

SECTION 7 – Alternative Proposed Wastewater Rates
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
7-1
7.1 Alternative Proposed Wastewater Rates (without new bond authorization)
The financial planning and rate design analyses presented in this Rate Proposal for WW are
contingent upon the authorization of an additional $750 million of revenue bonds by District
voters. If voters reject the District’s proposed revenue bond authorization, the District will need to
finance its major capital improvement program on a 100% PAYGO basis once current bonding
authorization of approximately $628 million is depleted, as shown in Table 7-1. In recognition of
this possibility, financial analyses identical to those presented earlier in this proposal were used to
reflect the impact of rates without the benefits of additional bond authorization.
This is a proposed scenario to be reviewed and considered if the additional bond authorization is
not approved by voters. The alternative rates also finance the entire CIRP previously presented by
Table 4-7. Due to the significant non-recurring expense of the fluidized bed incinerator project,
the alternative rates in this scenario increase sharply in FY 2025 and FY 2026 before decreasing;
rates do not decrease back to their 2025 levels in order to maintain funding capacity for capital
projects outside the FY 2025- FY 2028 period, though rate increases would be needed in that
period as well. This scenario requires a 37% increase in rate revenue in FY 2025, a 35% increase
in FY 2026, a 20% decrease in FY 2027, and 5% increases per year in FY 2028 and beyond. The
full financial plan in shown in Table 7-2, and the rate resulting from the cost-of-service process
change to those shown in Table 7-3. The typical single family customer bill throughout the Rate
Proposal timeframe is presented in Table 7-4 to show the impact of not using debt financing for
the CIRP beyond what has already been authorized.

Appendix 8.1 Key Proposal Assumptions
Appendix 8.1.1 Inflation Assumptions
Inflation assumptions are used in the rate model as a way to account for anticipated price increases
for the goods and services acquired by the District in fulfillment of its mission.
The District has chosen to use The Budget and Economic Outlook: 2022 to 2032 (1) published by
the Congressional Budget Office of the Congress of The United States (CBO) as a source for
inflation rates related to operations and maintenance expenses. Published in May of 2022, this
document provides a 10-year forecast that best matched the District’s rate model time horizon.
Figure 2-4 in that publication contains the Core PCE Price Index (excluding food and energy)
which the District used in the model for most expenses. The index ranged from 2.0 to 2.5 in the
years from 2023 to 2032, and The District has chosen to use a flat 2.1% for operating expenses
except in the case of salaries, benefits and utilities.
In that same figure, a Consumer Price Index reported numbers in the 2.0 to 2.3 range. This index
is computed differently, but most importantly it includes food and energy which were excluded
from the Core PCE Price Index. Since the index which includes energy forecasts a higher inflation
rate, a higher rate was used for utilities in the rate model. The District performed trend analyses
on utility expenses over a five-year time period. The combination of changes in usage and rate
over the last five years results in average increases of 5% for Natural Gas and 4% for Water which
were used in the rate model to predict future expenses for these utilities. The District has chosen
to use a 2.54% increase annually in the rate model to predict future electricity expenses based on

the 10-year compound annual growth rate on the retail price for Missouri industrial users.
Management provided the following criteria for salary growth rates.
For A Schedule, include a 4.0% per year increase
For B Schedule, include a 3.0% per year increase to each grade
For BT Schedule, include a 3.5% per year increase to each grade
For C (includes U) Schedule, include a 3.5% per year increase
Using these criteria, an analysis was performed to determine a blended growth rate for use in the
model. The first factor considered was that B and BT schedule employees that are not at the top
step receive not only the grade increase indicated above, but they also move up a step each year.
The step increases were modeled to take place halfway through each year. The resulting weighted
average increases for B and BT employees at the top step and those employees below the top step
were 3.66% and 3.62%, respectively. Finally, a weighted average annual increase for all
employees was computed to be 3.65%.
Group insurance was inflated at rates of 8.00% to 8.50% based on projections provided by the
District’s insurance consultant, Arthur J. Gallagher & Company (2). In the following pages the
projections provided by the District’s insurance consultant are reproduced.

Appendix 8.1.2 Wastewater CIRP Appropriation Adjustments
The project list that makes up the CIRP budget over this period consists of projects needed to meet
the region’s obligations under the consent decree. These include:
1. Projects identified in the SSO Master Plan to ensure system capacity and enable the
removal of sanitary sewer overflows
2. Projects to meet compliance with the CSO Long Term Control Plan
3. Projects to renew the wastewater system to meet consent decree goals
4. Projects to meet consent decree targets for Cityshed and Green Infrastructure investment
These consent decree specific projects are supported by numerous other capital program budget
items which are needed to deliver the program. Also, projects include reinvestment in the area’s
wastewater treatment and pump station facilities to ensure operating permit and air quality permit
compliance, sustainability, and the continued, proper operation of these industrial facilities. The
most significant of these include the replacement of sewage sludge incinerators to replace older
technology with new technology with much lower emissions. Where economically beneficial, a
number of sustainability projects are included to keep MSD cost competitive and efficient.
Projects are scheduled to build the highest priority projects first, while still meeting consent decree
deadlines. Many projects must be built in a specific sequence due to their size, the interaction
between various sections of the wastewater system, and to prevent any increase in environmental
pollution while the projects are being constructed.
The cost estimates that the CIRP budget is based on are conceptual in nature and are in fiscal year
2023 dollars, which were updated for inflation. At this stage, there is typically limited information
on public and private inflow and infiltration sources, and, for sewer and tunnel projects, a minimal
amount of detailed information available regarding geotechnical conditions, utility relocation
requirements, easement requirements, and other site-specific issues that have the potential to
significantly affect the project’s eventual construction cost. As projects proceed through design,
these issues are fully evaluated and their impacts are incorporated into final design cost estimates,
which are reflected annually in the District’s CIRP budget supplement, which details the capital
program anticipated for the next fiscal year.
For large or multi-year projects, budgeting incorporates a phasing approach, so that the annual
appropriation amount for a given project in a given year equals the anticipated spending need in
that year. For example, a tunnel project which is expected to take six years to construct will have
its budget spread out over those six years. This phasing is evaluated and implemented on a project-
by-project basis, and lessens the annual amount of appropriations requested, to better match
anticipated needs.

WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
8-8
To initiate the CIRP budget preparation, Engineering provides Finance with a project list,
including conceptual budget costs, as well as cost summary schedules that group projects in
multiple ways. The first grouping is by wastewater or stormwater. Wastewater projects are
additionally grouped by type, such as treatment plant, combined sewer overflow, or asset
management. The estimated costs are further broken down depending on whether they are for
engineering or construction services. These summary numbers are then adjusted for three different
factors.
The first adjustment involves inflating estimated costs to account for price increases between now
and the time the project starts. The Engineering News-Record 4 was the source for inflation
assumptions related to the CIRP. They provide, on their website, a city construction cost index
for their subscribers. After analyzing 10-years of data from that index, 3.7% was the rate employed
in the rate modeling process to annually inflate project cost estimates from fiscal year 2023 dollars.
The following page includes the index data and information about the calculation to arrive at 3.7%.
The second adjustment performed on the CIRP conceptual estimates accounts for delays in
appropriation timing that can occur, due to such factors as the easement acquisition process or
condemnation. Capital program appropriations are spread throughout the fiscal year, as it is
impractical to deliver the entire annual program immediately at the start of the fiscal year. When
delays occur, some appropriations will shift from one fiscal year to the next. Appropriations during
FY 2018 through FY 2022 averaged 93% of the annual budgeted appropriations. Using this 93%
factor, an appropriation delay was introduced into the numbers. The inflated costs for any given
year were reduced by 7%, and that 7% was shifted into the next fiscal year, thus reducing the total
expected appropriations slightly over the course of the 4-year rate cycle.
Finally, it is common for projects to finish with some of their related appropriations left unspent.
We refer to these dollars which are returned to fund balance at the end of a project as liquidations.
Liquidations occur if projects do not need to utilize their full utility relocation allowance, if the
full budget contingency for change orders is unused, or if final in place quantities of constructed
items are less than bid estimates. An analysis of completed projects revealed that on average,
9.28% of a project’s appropriation is liquidated at the end of the project. While the timing of these
liquidations vary from project to project, it is common for these liquidations to occur
approximately three years after the appropriation. Therefore, projected appropriations in each year
were decreased by 9.28% of appropriations three years prior. One exception to this adjustment
was made for the Fluidized Bed Incinerator (FBI) project. Due to the type of project, management
believes it is appropriate to expect all appropriations to be utilized. Therefore, no liquidation
adjustment is applied to the FBI project.

Through FY 2022, CAP enrollment was trending slightly better than projected during the March
2019 Rate Change Proposal. In FY 2019, many existing CAP accounts were required to reapply
to the program to show they were still eligible, but many did not. Since that time, modest increases
in enrollment have taken place.

Appendix 8.9 Impervious Area Determination
Building an impervious surface dataset that can be used for billing purposes is a process that begins
with Aerial Photography (See Figure 1). Aerial Photography must be flown before an impervious
surface can be captured. This flight is always scheduled at the beginning of the year when the
leaves are off the trees allowing technicians
more visibility when looking for impervious
surfaces. The photographs are also taken
orthogonally, or at a 90-degree angle to the
earth, to ensure proper perspective for area
measurements.
In the past, Aerial Photography was used by
technicians employing stereoscopic photo-
interpretation and planimetric techniques to
manually delineate outlines of various
impervious surface features such as Building
Main Structure Footprints, Paved Roads,
Driveways, Sidewalks, and others. The
original set of impervious surface outlines
was obtained by MSD in 2005 using Aerial
Photography from that time. Subsequently, new Aerial Photography flown in 2007, 2009, 2012,
2018, and 2020 was used to update the original data. With a view to increase efficiency and cost
effectiveness, footprints of existing structures were left unchanged, but any changes – such as
addition of new structures, or demolition or modification of existing structures – were used to
update the existing impervious surface outlines.
Aerial Photography was once again flown in
2022. This time however, digital files of the
aerial imagery will be processed by a
computer using Artificial Intelligence (AI)
algorithms to classify the image and delineate
footprints of the constituent ‘classes’
mentioned above, such as Building
Footprints, Sidewalks, Driveways, and
others. Replacing manual photo-
interpretation with AI algorithms will
achieve significant time savings overall, and
substantive cost savings in the medium and
long terms, all while achieving comparable
levels of accuracy and better levels of
currency.

Impervious surface boundaries are combined with Parcel boundaries (See Figure 2) to determine
the impervious area within each customer’s parcel and thus determine the dollar amount each
customer is billed. The City and County of St. Louis each maintain their own Parcel Base. MSD
obtains the two Parcel Bases and stitches them together into a single Parcel Base, taking care to
remove any overlaps. This precludes the possibility of double billing a customer.
The two basic datasets used in impervious surface billing - impervious surface boundaries with
their various classifications, and an integrated Parcel Base, are then processed by MSD to develop
a ‘billable’ impervious surface area for each customer. Impervious surfaces such as roads and
sidewalks in public areas and rights-of-way are removed because they cannot be attributed to a
particular customer since they are for public use and/or not located on a parcel assigned individual
ownership. Figure 3 shows an aerial photo with the parcel base and classified impervious surfaces.
Red indicates a main building, green is driveways, blue is patios, and yellow is private sidewalks.
For the updated impervious datasets, following the original capture, the process must also take
“Status” into account. During the update process, all impervious surfaces are assigned a status of
Existing, Modified, New, or Deleted. All surfaces with a status of Deleted are then left out of
calculations moving forward. Next, all impervious surfaces that exist outside of a parcel in the
right of way are clipped off to be removed.
The process then looks at the underlying
parcel data for the rest of the impervious
areas and determines with its land use code if
the parcel is residential or not. The parcel
information that MSD receives does not
always align with impervious surfaces, so
efforts are made to ensure the data is
correctly handled for billing purposes. For
example, residential properties are typically
located within property lines. Therefore, in
the event that a home or driveway is shown
slightly crossing a property line, the
impervious surface will be assigned to the
parcel where it has the greatest overlap. The
parcels are not adjusted because MSD does
not own that data and leaves the maintenance
to the St. Louis City and County. Because nonresidential scenarios can vary so greatly, all
impervious surfaces on them are split on the property line. As both residential and nonresidential
impervious surfaces are being processed, they are assigned the Parcel Identification Number (PIN)
of the parcel they sit on. This final set of impervious surfaces that have been clipped, and assigned
the proper attributes is called Assigned Impervious. Using this data, impervious area totals can be
figured for every customer and provided to billing.

Appendix 8.10 Assessed Valuation Trend Analysis
Appendix 8.11 Stormwater CIRP Appropriation Adjustments
The project list that makes up the stormwater CIRP budget over this period consists of projects
needed to meet the region’s needs to provide proper stormwater management. MSD monitors
the District’s watersheds and maintains a customer service and managed maintenance system
that records customer complaints. Based on this information, MSD then identifies projects to
address specific stormwater problem areas. The current database of projects includes 561
projects with a conceptual cost estimate of $696 million in the following categories: regional
flooding, local flooding, erosion, and other types of projects.
To initiate the rate case preparation, Engineering provides Finance with a project list, including
conceptual budget costs, as well as cost summary schedules that group projects in multiple
ways. The first grouping is by funding source; taxes, fund balance or capital rate. The estimated
costs are further broken down depending on whether they are for engineering or construction
services. These summary numbers are then adjusted for three different factors.
The first adjustment involves inflating estimated costs to account for price increases between
now and the time the project starts. The Engineering News-Record was the source for inflation
assumptions related to the CIRP. They provide, on their website, a city construction cost index
for their subscribers. After analyzing 10-years of data from that index, 3.7% was the rate
employed in the rate modeling process to annually inflate project cost estimates from fiscal year
2023 dollars. The following page includes the index data and information about the calculation
to arrive at 3.7%.
The second adjustment performed on the CIRP conceptual estimates accounts for delays in
appropriation timing that can occur, due to such factors as the easement acquisition process or
condemnation. Capital program appropriations are spread throughout the fiscal year, as it is
SECTION 8 – Appendices
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL
8-60
impractical to deliver the entire annual program immediately at the start of the fiscal year. When
delays occur, some appropriations will shift from one fiscal year to the next. Appropriations
during FY 2018 through FY 2022 averaged 93% of the annual budgeted appropriations. Using this
93% factor, an appropriation delay was introduced into the numbers. The inflated costs for any
given year were reduced by 7%, and that 7% was shifted into the next fiscal year, thus reducing
the total expected appropriations slightly over the course of the 4-year rate cycle.
Finally, it is common for projects to finish with some of their related appropriations left unspent.
We refer to these dollars which are returned to fund balance at the end of a project as liquidations.
Liquidations occur if projects do not need to utilize their full utility relocation allowance, if the
full budget contingency for change orders is unused, or if final in place quantities of constructed
items are less than bid estimates. An analysis of completed projects revealed that on average,
9.28% of a project’s appropriation is liquidated at the end of the project. While the timing of these
liquidations vary from project to project, it is common for these liquidations to occur
approximately three years after the appropriation. Therefore, projected appropriations in each year
were decreased by 9.28% of appropriations three years prior.

Appendix 8.12 Stormwater CIRP Description
The stormwater CIRP (see appendix 8.12.2 of the Rate Change Proposal) provides a listing,
schedule and cost of needed additions and improvements to the stormwater sewer and drainage
system to address issues of flooding, erosion, and maintenance.
The stormwater CIRP is primarily made up of projects identified from historical records and
engineering studies to address customer complaints about flooding and erosion. Identified projects
are segmented into three main categories: Local Flooding (small scale flooding caused by
overland flow or smaller streams), Regional Flooding (large scale flooding in locations of major
creeks and rivers), and Erosion (loosening and washing away of soil due to the actions of water,
usually adjacent to creeks and rivers). More specifically, types of stormwater flooding problems
listed in order of severity include structure flooding, roadway flooding, and yard flooding. Types
of erosion problems listed in order of severity include stream erosion threatening a structure,
stream erosion threatening a road, and yard erosion. The CIRP includes the proposed funding for
planning, design, construction, easement acquisition, buyouts, and general service agreements for
support services such as survey, system investigation and geotechnical services necessary to
accomplish this work, as well as repair and replacement of existing stormwater infrastructure
failing due to age.
The District currently has identified 159 million dollars for the stormwater CIRP for fiscal years
2025 through 2028, which includes 79 projects to address flooding and erosion issues to be
constructed. The projects currently identified will require approximately 78 million dollars to
complete. The stormwater CIRP also includes 46 million in funding for stormwater grants to third
parties to promote flooding and erosion control, and green infrastructure. In addition, the
stormwater CIRP includes 35 million dollars for construction of repairs and rehabilitation of the
existing stormwater system over those years, funded with the District’s O & M tax. MSD will
continue to assess the existing project listing and anticipates additional projects will be identified
as new issues arise.
The District is proposing a new stormwater rate with revenue collected by the use of property taxes
for residential customers and an impervious area rate for non-residential customers. MSD’s
program goal will be to expend the revenues in four buckets: 50% of the program to be allocated
to the Districtwide projects prioritized by our current benefit/cost (B/C) ratio; 10% for a
stormwater resiliency fund; 10% used for projects in identified Environmental Justice (EJ) areas
of the District using the B/C methodology for prioritization; and 30% offered as municipal grants.
Some capacity in the proposed new stormwater rate’s 50% bucket has been left unprogrammed,
as a reserve for newly identified high priority projects that we expect will arise as the program is
implemented.
SECTION 8 – Appendices
Metropolitan St. Louis Sewer District
WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL

For the 10% of the program allocated to a stormwater resiliency fund, MSD would present its
recommendations for the expenditure of these funds to an advisory committee (currently
anticipated to come from the Municipal League of Metro St. Louis plus a representative from the
City of St. Louis) which would also consider project needs from other sources. The advisory
committee would convey its recommendations to the MSD staff, but MSD would hold the right of
final decision making. Any unused funds from this 10% would be defaulted back to the 50%
Districtwide program.
The District proposes to allocate 10% of the revenue generated by a new stormwater rate to focus
capital improvement work to be constructed by the District in underserved areas. MSD has
identified environmental justice areas within the District by using “qualified census tracts”. A
qualified census tract (QCT) is defined under the Internal Revenue Code as any census tract which
is designated by the Secretary of Housing and Urban Development (HUD), that (for the most recent
year for which census data is available on household income in the tract), either 50 percent or more
of the households have an income which is less than 60 percent of the area median gross income
(AMGI) for the year, or which has a poverty rate of at least 25 percent. This methodology was
utilized for submitting EJ criteria for State of Missouri ARPA grant funding and was found to be
acceptable. The geographic area for these projects has been defined, and the capital improvement
program costs have been identified for projects within these areas using the District’s normal
benefit/cost prioritization process. More details can be found in appendix 8.16 and 8.17 of the
Rate Proposal.
The District proposes to offer approximately 30% of the revenue generated by a new stormwater
rate to municipalities in the form of grants. These grants would facilitate local stormwater
priorities being addressed at the local level. This grant program would be modeled on the
successful OMCI taxing district grant program for municipalities that has been implemented by
the District over the last few years. This grant revenue would be offered to municipalities based
on population. 7 population ranges or groupings are envisioned, with each municipality within a
given range receiving the same grant amount. Grants would range from $30,000 to $1,550,000.
More details can be found in appendix 18 of the Rate Proposal. Unused funds from the 30%
municipal grants program would be made available for projects in the Districtwide program (50%)
or the EJ program (10%) as appropriate.

Appendix 8.14 Revised Stormwater Policy
The existing Stormwater Policy is contained in Exhibit MSD 64. If the proposed stormwater
capital rate is approved Section 3.5 of the Stormwater Policy would be revised as shown below.
3.5 Capital Improvement Projects: MSD maintains a Districtwide revenue source for the
funding of stormwater capital improvement projects. The stormwater Capital Improvement
and Replacement Program (CIRP) is made up of projects identified from historical records and
engineering studies to address flooding and erosion issues reported to and confirmed by the
District. Identified projects are segmented into three main categories: Local Flooding,
Regional Flooding, and Erosion. More specifically, types of stormwater flooding problems
listed in order of severity include but are not limited to structure flooding, roadway flooding,
and yard flooding. Types of erosion problems listed in order of severity include but are not
limited to stream erosion threatening a structure, stream erosion threatening a road, and yard
erosion. As projects are identified, these severity categories are used to prioritize the
projects. Project solutions may include the design and construction of new storm sewer
systems, storm system upgrades, storm system extensions, stormwater detention, property
buyouts, channel protection and restoration, or green infrastructure improvements. Projects
are implemented annually based on priority and availability of funds.

Appendix 8.15 Property Tax Alternative
Appendix 8.16 Environmental Justice
The Metropolitan St. Louis Sewer District (District) proposes to allocate 10% of the revenue
generated by the new stormwater capital charges to focus capital improvement work in
environmental justice (EJ) areas identified through Missouri state guidelines. This allocation of
funds would deliver capital improvements on stormwater priorities being addressed within these
EJ areas. The geographic area for these projects has been defined, and the capital improvement
program costs have been identified for projects within these areas using the District’s normal
benefit/cost prioritization process.
To implement the program fairly, and ensure equality and equity in the decision-making process,
the state guidelines for EJ areas use the term “qualified census tract”. A qualified census tract
(QCT) is defined under the Internal Revenue Code as any census tract which is designated by the
Secretary of Housing and Urban Development (HUD), and for the most recent year for which
census data are available on household income in the tract, either in which 50 percent or more of
the households have an income which is less than 60 percent of the area median gross income
(AMGI) for the year, or which has a poverty rate of at least 25 percent. The Missouri Department
SECTION 8 – Appendices

WASTEWATER AND STORMWATER RATE CHANGE PROPOSAL

of Natural Resources considered this term in prioritizing the distribution of federal grant funds
related to the American Rescue Plan Act. The source data consisting of HUD defined QCTs was
downloaded from the following link:
https://hudgis-hud.opendata.arcgis.com/datasets/HUD::qualified-census-tracts/about .
A map has been generated to identify projects within the environmental justice areas. The map
includes all QCT tracts within the District.

Appendix 8.18 Proposed Grant Program
The Metropolitan St. Louis Sewer District (District) proposes to offer approximately 30% of the
revenue generated by a new stormwater rate to municipalities in the form of grants. These grants
would facilitate local stormwater priorities being addressed at the local level. This grant program
would be modeled on the successful OMCI taxing district grant program for municipalities that
has been implemented by the District over the last few years.
This grant revenue would be offered to municipalities based on population. 7 population ranges
or groupings are envisioned, with each municipality within a range receiving the same grant
amount. For instance, any municipality with a population of less than 1,000 would be eligible for
a $30,000 grant annually, while at the upper range those municipalities with populations between
20,001 and 100,000 would be eligible for a $300,000 grant annually. Unincorporated St. Louis

GLOSSARY
Ad Valorem Tax: A state or local tax based on the assessed value of real or personal property.
Assessed Value: Assessed value is the appraised value multiplied by a statutory assessment
percentage (e.g., 19% for residential, 32% for commercial).
Appraised valuation determines the value of a residence for tax purposes and takes comparable
home sales and inspections into consideration. It is the price placed on a home by the
corresponding government municipality to calculate property taxes.
Base Charge: Fixed monthly wastewater service charge that is equal to the sum of the Billing and
Collection Charge and the System Availability Charge.
Best Equated Period: MSD defines its best equated period as a 90-to-92-day period of water
usage between November and April of the preceding winter period. This period most closely
reflects the water entering the MSD WW system by avoiding spring and summer water usage for
activities such as lawn sprinkling and the filling of swimming pools.
However, if a water bill issued during such period covers water usage for a period less than 90
days or more than 92 days, the Best Equated Period shall mean a 91-day period and water usage
shall be calculated based on average daily usage for the actual billing period.
Billing and Collection Charge: Monthly charge imposed by the District to recover the wastewater
program’s share of the costs associated with issuing and collecting wastewater and bills.
Biochemical Oxygen Demand (BOD): A measure of the quantity of oxygen utilized by
microorganisms to break down complex organic materials into simple, more stable substances.
BOD measurements are used as a measure of the organic strength of wastewater.
Board: Refers to the Board of Trustees of the District. The Board is comprised of six (6) members,
three appointed by the Mayor of the City of St. Louis and three appointed by the County Executive
of St. Louis County.
Bondholder: The registered owner of one or more Bonds issued by the District.
Bonds: This financial instrument means: a certificate issued by a government or company
promising to pay back borrowed money at a fixed rate of interest on a specified date. The term
“Bonds” within this Rate Proposal includes, but is not limited to, obligation in the form of bonds,
notes, contracts, lease obligations, bond anticipation notes, commercial paper, and certificates of
participation. The term “Bond” or “Bonds” does not include any obligations incurred by the
District on a subordinated basis.

Budget: An estimate of proposed expenditures for a defined period and purpose and a schedule of
revenues available to finance the proposed expenditures.
Capacity: The maximum rate of flow that can be carried by a sewer or received by a treatment
plant without causing an upset of the biological material contained within that treatment system.
Capital Improvement and Replacement Program: Refers to the District’s comprehensive plan
consisting of construction and/or renovation of major sewer system and wastewater treatment plant
projects intending to enhance or restore system capabilities.
Clean Water Act: Common term for the Federal Water Pollution Control Act of 1948, with major
amendments in 1972 (PL 92 500), in 1977 by the Clean Water Act (PL 95 217) and in 1987 by the
Water Quality Act (PL 100 4), as further amended, 33 U.S.C. 1251, et seq.
Code of Federal Regulations: Law of the United States issued under several Titles. Title 40
deals with protection of the environment. Part 35 deals with specific regulations, including user
charge requirements for wastewater utilities that have accepted construction grants from the
Federal Government, which may be found at:
http://www.ecfr.gov/cgi-bin/text-idx?tpl=/ecfrbrowse/Title40/40cfr35_main_02.tpl
Combined Sewers: Sewers designed and constructed to receive both wastewater and
stormwater or surface water.
Compliance Charge: A charge imposed by the District that recovers costs for inspecting and
regulating non-residential users in accordance with certain federal environmental regulations. This
charge is recovered from all non-residential customers. Non-residential customers are assessed one
of five tiered compliance charges based on the amount of inspection and testing of WW needed to
comply with current regulations. Extra strength surcharges are applied to monitored non-
residential customers generating excess biochemical oxygen demand (BOD), chemical oxygen
demand (COD) and total suspended solids (TSS).
Consent Decree: Agreement between MSD (“District”), the EPA, and the Missouri Coalition for
the Environment settling litigation related to alleged violations of the Clean Water Act by the
District and requiring expenditures of at least $4.7 billion (in 2010 dollars) over 23 years to prevent
future violations. The Consent Decree went into effect on April 27, 2012. In 2018, the Consent
Decree was extended by five years due to regulatory changes that compelled the District to
accelerate certain projects that do not fall within the scope of the Consent Decree. The time
extension allowed the District to address new regulatory requirements in a fiscally responsible
manner. The Consent Decree was amended in 2023 to allow the District to replace two wastewater
storage tunnels with a single storage tunnel. The single tunnel limits the impact on nearby

Contributed (Billable) Wastewater Volume: Billed WW volume is the estimated amount
of water volume contributed to the sewer system by MSD customers. This volume is measured on
either a metered or unmetered basis. The amount of contributed WW volume from metered
customers is measured in Ccfs (One Hundred (100)) cubic feet (approximately 748 gallons).
The volume from unmetered residential customers is likewise measured in Ccfs as determined
based upon estimates of indoor water usage per fixture and the number of rooms within these
properties referred to as attributes throughout the Rate Proposal.
Based on analysis, the unit water consumption estimates of gallons per day (gpd) was used to
calibrate billable WW volumes based on property attributes applicable to unmetered single family
and multi-family customers. These volumes are:
Attribute Assumed Volume
Contributions
Rooms 12.5 gpd
Water Closet 46.7 gpd
Baths 40.0 gpd
Separate Showers 40.0 gpd
Cost Allocation: Process of distributing cost of service (revenue requirements to be
recovered from rates) to Functional Cost Components and then to Customer Classes on the basis
of their relative use of the system (Units of Service) through application of unit costs.
Customer Class: A group of customers having homogeneous characteristics.
Customer Costs: Costs which tend to vary in proportion to the number of customers
connected to the system. These include costs related to acquisition of water utility billing data,
billing, collecting and accounting.
Customer Impact: The financial restraints possible from the results of the proposed rate
adjustments on typical residential, commercial and industrial customers of the District.
