1 Exhibit MSD 1 METROPOLITAN ST. LOUIS SEWER DISTRICT RATE CHANGE PROPOSAL FEBRUARY 26, 2015

2 INTRODUCTION The Metropolitan St. Louis Sewer District (MSD) was formed on February 9, 1954, when voters approved the Plan of the Districtt 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 composedd 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 extensivee system of collector and interceptor sewerss and treatment facilities. Most of the remainder of St. Louis County was annexed by MSD in MSD s Rate Commission was established in 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 mayy 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 andd is based on the strategic and financial implications of its regulatory defined Wastewater (WW) and Stormwater (SW) service obligations to the St. Louis region. The District s development of its Rate Proposal reflects consultative and analytical assistance from Raftelis Financial Consultants, Inc. ( RFC) and Vertex Business Services (Vertex). Raftelis Financial Consultants Inc. (RFC) RFC is a financial consulting firm specializing in rate design, financial planning, bond feasibility studies for water, wastewater and SW utilities. Headquartered in Kansas City, RFC has offices in North Carolina, California, Ohio, Colorado and Texas. RFC conducted a comprehensive analysis of the District s current and projected funding needs. Based on thiss analysis, RFC designed the wastewater rates and SW funding approach contained inn the District s Rate Proposal. RFC will also assist the District in articulating the complexities underlying its proposed rates and analyze alternative rate designs and Rate Proposals as presented during the Commission s review. RFC developed the WW and SW rates contained in the Rate Proposal based on industry standard rate design methods. The Proposed rates were calculated using an RFC rate model customized

3 for the District s unique needs. A flash drive containing this model is included as part of the Rate Proposal. Vertex Business Services (Vertex) Vertex is a consulting and technology solution provider serving water/wastewater, electricc and natural gas utilities across North America. Headquartere ed in Richardson, Texas, Vertex currently hosts the District s billing and collection system and on-site calll center giving them unique access to detailed data on the District s WWW and SW revenues, customer accounts, water usage and customer behaviors and attributes. Vertex s Analytics and Consulting practice assisted the District in bridging its billing and collection data with outside dataa sources as the basis for key assumptions in the District s Rate Proposal. Vertex worked in conjunction with RFC to develop the customer growth and water usage projections used in the rate design; determine the universe of potential ratepayers who may benefit from the District s Customer Assistance Program; provide data to recalibrate the Ccf (centum cubic feet or 100 cubic feet) basis for thee District s unmetered wastewater rate components, and provide detailed taxpayer attributes to assess the customer impact of the District ss WW and SW charges contained in this Rate Proposal. Public Financial Management, Inc (PFM) The PFM Group, ncluding Public Financial Management Inc. (PFM) and its affiliates, is a national leader in providing independent financial advice as well as investment advisory, management and consulting services to local, state, and regional government and nonprofit clients. Headquarter red in Philadelphia, Pennsylvania, ass of December 2014, the PFM Group has 37 locations nationwide. Nine of these offices are located in the Midwest, including an office in St. Louis. PFM has served as the District ss financial advisor since 2000, advising on all aspects of District debt policy development, financial planning, debt transaction management including credit structure development and credit ratings presentations s and on-going debt monitoring. PFM worked with the District to develop a financial plan in considerationn of this Rate Proposal to the Commission. The financial plan recommends senior lien debt issuance levels designed with the objectivee to maintain credit ratings metrics consistent with strong credit ratings and in consideration of the District s operational and capital funding needs..

4 RATE PROPOSAL ORGANIZATION WASTEWATER & STORMWATER RATE CHANGE PROPOSAL RATE PROPOSAL ORGANIZATION The Rate Proposal is organized into 9 Sections outlined below. Rate Proposal Sections: Section 1 Section 2 Section 3 Section 4 Section 5 Section 6 Section 7 Section 8 Section 9 Abbreviations and Acronyms Rate Table & Figure Index Executive Summary Proposed Wastewater Rates Proposed Stormwater Funding Customer Impact Appendices Glossary Index Flash Drive A flash drive accompanies the Rate Proposal to provide easier accessibility to this document. It also contains the District s Direct Testimony, RFC rate design model used by the District and supplemental exhibits anticipated to be used during the Commission s review. A summary of each section follows: SECTION 1 Abbreviations and Acronyms This section contains a list of definitions of the abbreviations and acronyms frequently used in the Rate Proposal. SECTION 2 Rate Table & Figure Index This section contains a listing of all the numeric tables and graphs. SECTION 3 -- Executive Summary This section provides an overview of the proposed WW rates and SW funding presented in this Rate Proposal. This section also outlines the basic construct and foundational assumptions underlying the District s rate change request including the impact on its customers. P.O.- 1

5 RATE PROPOSAL ORGANIZATION WASTEWATER & STORMWATER RATE CHANGE PROPOSAL SECTION 4 -- Proposed Wastewater Rates This section provides the details of the District s proposed change in its WW 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. 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 4 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. This Section also provides a 100% user charge (PAYGO) scenario as an alternative to incurring additional debt. Additional detail supporting the assumptions used to design the proposed change in WW rates may be found in the Appendices in Section 7. SECTION 5 -- Proposed Stormwater Funding This section provides the details of the District s proposed plan to fund SW operations within its boundaries. This proposed funding plan replaces the SW impervious based fee structure, as approved by the Rate Commission in calendar year The SW impervious based fee structure was found by the Missouri Supreme Court to be a tax that required voter approval. MSD proposes the use of a District-wide tax structure to replace the flat rate charge and the multi-layered taxes now assessed on the real estate value of its customers property. This proposed funding is designed to cover the cost of SW maintenance services, limited capital projects and associated O&M. This section provides the basis for the District s SW component of its Rate Proposal, its underlying assumptions, proposed tax structure and impact on MSD customers. Additional details supporting the assumptions can be found in the Appendices in Section 7. SECTION 6 Customer Impact This section provides information on the impacts of the proposed rate adjustments on typical residential, commercial and industrial customers of the District. This section also discusses implications of the proposed rate adjustments relative to customer impacts within the District. SECTION 7 -- Appendices This section contains 7 appendices providing additional detail underlying the key assumptions used in the District s rate design. SECTION 8 Glossary SECTION 9 - Index P.O.- 2

11 SECTION 3 EXECUTIVE SUMMARY EXECUTIVE SUMMARY WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 3.1 Existing WW and SW Billing Structures Wastewater All customers pay a volume charge based on their water usage as provided by their respective water providers. The billing rate 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 usage charged on a per Ccf basis. Single family and multi-family customers in the City of St. Louis are primarily unmetered with water usage charged on a per attribute basis. All non-residential customers are metered and billed monthly. 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 Stormwater The SW user charge is assessed to all properties in the MSD service area. Single-family and nonresidential customers are charged a monthly 24 fee. Multi-family accounts are charged 18 per unit per month. In addition a property tax is assessed to each taxable property in the MSD service area. The amount of the tax levy ranges from $.0197 to $.1879 per $100 of assessed value depending where the property is located. Figure ES-1 provides a summary of the various taxing districts: those properties in red pay a levy of $.0197 per $100 of assessed value, those in yellow pay levies of $.0682 and $.0197 per $100 of assessed value while those in the green areas pay levies totaling a minimum of $.0879 to a maximum of $.1879 per $100 of assessed value.

13 SECTION 3 EXECUTIVE SUMMARY 3.2 WW Rate Proposal WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The District s proposed WW rates are based on rate design application and analysis conducted by MSD s rate consultant, RFC in conjunction with District staff. The principal assumptions used in the WW Rate Proposal are as follows: 1. RFC has relied on certain historical, financial and statistical data supplied by District staff. While such data is considered reliable, RFC has not independently verified or audited the detailed accuracy of such data. 2. Billed WW volume will decrease throughout the forecast period, consistent with historic District and industry trends, as analyzed by the Vertex Group and presented in Appendices and 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 The District s estimates of content, scheduling and cost of the four-year WW CIRP totaling approximately $1.50 billion for FY17 through FY20 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 and 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, 2016 to June 30, 2020, includes increases in WW charges, as well as $918.6 million in senior revenue bonds to help fund approximately $1.49 billion in needed improvements over the forecast period. MSD does not anticipate receiving financial support from the federal government for this construction program other than the $100 million in federallyfunded and state-administered subordinate series of revenue bonds issued under the Missouri State Revolving Fund (SRF) financing shown in the CIRP financing plan. More details on the CIRP financing plan can be found in Section A Bond election will be held in calendar year 2016 and the District voters will authorize $900 million of additional WW revenue bonds. 7. If the District does not obtain additional revenue bond authority, the Board will approve the alternative WW rates presented in Table 4-24 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 $477.2 million, as estimated. 9. The District will maintain a minimum operating reserve balance at all times that is at least equal to 60 days of operating expenditures. ES- 3

14 SECTION 3 EXECUTIVE SUMMARY WASTEWATER & STORMWATER RATE CHANGE PROPOSAL Overall the analyses indicate that the District will require increases in revenues averaging 9.8% each year of 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.

15 SECTION 3 EXECUTIVE SUMMARY WASTEWATER & STORMWATER RATE CHANGE PROPOSAL RFC performed a detailed cost of service analysis using industry standard principles endorsed by the 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.

ES- 5

16 SECTION 3 EXECUTIVE SUMMARY 3.3 SW Rate Proposal WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The District s proposed SW rates are based on rate design application and analysis conducted by MSD s rate consultant, RFC, in conjunction with District staff. The principal assumptions used in the SW Rate Proposal are as follows: 1. RFC has relied on certain historical, financial and statistical data supplied by District staff. While such data is considered reliable, RFC has not independently verified or audited the detailed accuracy of such data. 2. Total taxable assessed property value will increase slightly over the forecast period as projected by District staff. 3. The District s SW O&M expense will have inflationary increases over the forecast period as shown in Section of this Rate Proposal and discussed in more detail in Appendix The District s estimates of content, scheduling and cost of the four-year SW CIRP totaling approximately $70.9 million for FY17 through FY20 present a reasonable projection of the future construction program. More details about the District s SW CIRP can be found in Section and Appendix of this Rate Proposal. The SW CIRP is funded without the use of debt to fund SW capital improvements. The funding approach contained in this Rate Proposal for the District s SW operations proposes to simplify the funding structure by replacing the patchwork of various tax levies discussed previously in Section with a uniform levy of the existing $.0197 to recover the cost of providing regulatory compliance services throughout the District s service area as well as a $.10 levy throughout the District s service area (except for properties served by a levee district) to provide a more uniform level of service throughout the District. A more detailed discussion of the service levels to be provided by the District under this proposed funding is contained in Appendix The overall financial plan for the District s SW operations based on these assumptions and proposed revenues is shown in Table ES-3.

18 SECTION 3 EXECUTIVE SUMMARY 3.4 Total Impact on Customer Bills WASTEWATER & STORMWATER RATE CHANGE PROPOSAL Table ES-4 presents a comparison of typical WW service bills under existing rates, rates currently approved through FY16, and under the proposed FY17 through FY20 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 7 Ccf of WW each month to the sewer system is projected to increase $20.14 from FY16 to FY20 (about 10.6% on average in each year from FY17 through FY20). Table ES-4 Typical Monthly Wastewater Bills Historical Approved Projected FY 2013 FY 2014 FY 2015 FY 2016 FY 2017 FY 2018 FY 2019 FY 2020 Wastewater Bills Single Family Residential (Metered) 1. 1 ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ ccf per month (Typical Customer) $ $ $ $ $ $ $ $ % Change 13.1% 9.8% 10.8% 10.8% 10.8% ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ Multi-Family Residential (Metered) ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ Non-Residential (Normal Strength Wastewater) ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ Non-Residential (Excess Strength Wastewater) (1) ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ ccf per month $ $ $ $ $ $ $ $ 1, (1) The 70, 100, and 160 ccf bills assume excess strength of 150, 200, and 250 mg/l, respectively, of suspended solids and BOD. Billable WW volumes for unmetered customers are derived from volumes associated with certain 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 very close to the billable volume of a typical metered residential customer. Table ES-5 presents sample unmetered bill impacts. The WW bill for a typical unmetered residential customer contributing 7.7 Ccf of WW each month would increase by $17.86 or by 9.1% on average each year from FY17 to FY20. ES- 8

22 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL PROPOSED WASTEWATER RATES 4.1 Current Wastewater Rate Structure The District s current WW rate structure consists of monthly service charges and volume charges applicable to all MSD customers. All non-residential customers are also assessed a compliance charge and extra strength charges where applicable. The monthly service charges include a billing and collection charge and a system availability charge. A volume charge is assessed to all customers based on their respective water usage. Water usage information is provided by customers respective water provider on either a metered or unmetered basis. 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. 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, 2014 and the approved rates for FY16 will go into effect on July 1,

24 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 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 rate components discussedd earlier to each and non-residential. MSD s WW revenue reflects the assessment of the specific 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 WWW customerss served by the District are providedd in Figure 4-1 and Table 4-2 below. The projected change in the number of customers is based on a 10 year average historical trend using a US Census based cohort-component methodology. As indicated in Table 4-2, the number off total customer accounts declined by an average of 0.26% annually between FY 2011 and FY Based on this trend, the number of customer accounts is projected to decline by 0.1% annually throughout the forecast. Additional detail on the development of this assumption can be found in Appendix Figure 4-1 Wastewater Customer Accounts 4-3

26 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 4.3 Contributed Volumes and Wastewater Flows 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 Ccf s (one hundred (100) cubic feet, which equates to approximately 748 gallons). The volume from unmetered residential customers is 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 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. The District engaged Vertex Business Services to assist in analyzing the relationship of water usage between metered and unmetered residential customers. This analysis was performed by members of Vertex s Analytics and Consulting practice using a combination of actual District data and multivariate analytics. The analysis determined the demographic drivers of water volume among metered customers, then applied those drivers to unmetered customers with identical matching demographic profiles. Based on this analysis, the unit water consumption estimates of gallons per day (gpd) was used to recalibrate billable WW volumes based on property attributes applicable to unmetered single family and multi-family customers. Additional detail regarding this analysis can be found in Appendix Attribute Rooms Water Closet Baths Separate Showers Assumed Volume Contributions 14.5 gpd 54.2 gpd 45.2 gpd 45.2 gpd 4-5

27 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The contributed WWW volume of all non-residential customers is measured on a metered basis and billed based on actual quarterly usage less applicable exemption allowances for any water that does not enter the sewer system. Metered multi-family customers are either billed based on 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 contributed, or billed, WW volume.

29 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The projections of contributed volumes are based on the historical trends in billed volumes and number of customers per customer class. Since FY06, the District has experienced annual reductions in total billed volumes of approximately 3.0%, which is a cumulative 24% 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 FY15 volumes by an overall average of 0.91% annually. Additional information related to this assumption can be found in Appendix The FY14 reduction was partially impacted by discontinuities in data that were experienced by Missouri American Water during implementation of a new customer information system. This has been reconciled and is anticipated to return to typical levels in FY15 and beyond. 4.4 Historical and Projected Wastewater Revenue from Existing Rates WW revenue under the approved rates for the period FY13 through FY20 is presented in Table 4-4 on the next page. Estimated revenues for FY17 through FY20 use FY16 approved rates. The District s historical WW revenue for FY13 and FY14 is based on actual rates, customer account and usage data. Projected revenue from WW user charges are based on projected customer demands and the rates approved through FY16 (revenue in FY17-FY20 assumes no changes in the approved rates for FY16). Projected billed WW revenue does not include allowances for bad debt, refunds or billing adjustments. These billing adjustments are included with other operating revenues in Table 4-5. The WW user charge revenue under existing rates increased from $236.1 million in FY13 to a projected $313.6 million in FY16. This change is due to a combination of key factors: approved rate increases, the impact of economic conditions, projected fluctuations in excess strength WW revenue due to more extensive pre-treatment programs and projected decreases in WW volume consistent with historical trends. As customer volumes continue to decline over the projection period, the revenue would be expected to decline as well. 4-8

31 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The projection of other WW revenue is presented in Table 4-5. 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 projected at 1.5% of total WW user charge revenue throughout the forecast. This projection is based on predicting the propensity to pay for all MSD customers with account balances delinquent greater than 30 days. The methodology used in the Rate Proposal matches that used to determine the provision for bad debt in the District s audited statements ending June 30, The change to this calculation resulted in a net revenue, rather than expense, for bad debt in FY14 of $7.2 million as shown in Table 4-5, line 2. Additional detail on this propensity-to-pay analysis may be found in Appendix Revenue from inspection and plan review fees are projected to remain stable throughout the forecast. Waste hauler permit revenue is projected to decline dramatically from FY14 levels when the Bridgeton landfill begins treating and piping leachate rather than trucking it to MSD for treatment. Other non-operating revenue in FY14 is negative $4.9 million due to demolition of assets in the trickling filter and secondary clarifier areas at the Missouri River WWTP. These assets, with a combined book value of $5.1 million, were removed as part of a project to expand the treatment plant and add disinfection facilities. All other miscellaneous revenue is projected to also remain stable at currently budgeted levels. Based on these projections, total other operating WW revenue is forecasted to decline from a budgeted amount of $5.7 million in FY15 to $1.6 million in FY20. The reduction is primarily due to the increases in the bad debt provision as WW user charge revenue increases. 4-10

33 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 4.5 Wastewater Operating Expenses The revenue needed to support the O&M 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 Wastewater Operation and Maintenance Expense A summary of projected WW O&M for FY15 through FY20 is presented in Table 4-6. These projections are based on the principle 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 FY15 budget estimates through the proposed 4-year rate cycle ending in FY20. Inflation percentages vary by expense type. Salary expenses and other related lines are inflated annually at rates between 3.1% and 3.2% for the years FY17 to FY20. Health Insurance expense is projected to increase annually at rates between 8.1% and 9.6%, while general supplies and contractual services are expected to increase annually between 1.9% and 2.0% over the same four-year period. More detailed information regarding inflation rates is provided in Appendix Incremental and additional one-time O&M costs are presented on line 22 of Table 4-6. Future WW O&M expense is projected to increase from $169.4 million in FY15 to $193.1 in FY 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 4-12

34 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL minor improvement or repairs (Line 25 of Table 4-6). 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 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. 4-13

36 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 4.6 Wastewater Major Capital Improvement & Replacement Program The primary cost driver for the District s financial plan is the CIRP. The District has agreed to a multi-decade, $4.7 billion (20100 dollars) CD program with the US EPA and Missouri Coalition for the Environment Foundation. This program requiress the District to make investments in the WW system to eliminate sanitary sewer overflows (SSO), combined sewer overflows (CSO) and help reduce the risk of flooding customer properties. The District s Engineering department regularly updates the scheduling of CIRP projects to ensure compliance with the CD. The current estimated CIRP needs are presented in Figure 4-3 and Table 4-7 for FY15 through FY20. The total CIRP project cost for this six-year period is projected to be $1.975 billion. The largest component of the CIRP over the next six years will be capital investments related to mitigating SSOs throughout the WW system. Additional needs include other improvements to comply with regulatory requirements outside of the CD and the rehabilitation and replacement of existing system assets. CSO projects begin to substantially impact the CIRP as this component reaches $158.3 million in FY20. Table 4-7 presents the summary CIRP needs throughout the 4-year proposed rate cycle. Additional detail on the long-term CIRP is presented in Appendix Figure 4-3 Projected CIRP Needs 4-15

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, line 10) are more appropriately financed with PAYGO revenue generated from annual WW service revenue. District staff, together with their financial advisor, Public Financial Management, Inc (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, Missouri SRF loans, grants and contributions, and interest income.

38 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL New senior revenue bonds totaling par value of $1.07 billion and $180 million in additional SRF loans are expected to be issued between FY15 and FY20 to provide this funding. At the end of FY16, it is estimated the District will have issued approximately 70% of its current debt authorization of $945 million. This will require the District to obtain voter approval for authorization of $900 million of additional debt financing prior to FY18. As indicated by Line 6 of Table 4-8, the District plans to take advantage of the SRF loan program but expects to be limited to $25 million each year from FY17 through FY20. Total senior revenue bonds and SRF loans are expected to finance approximately 69% of the six-year major capital improvement program costs. The amount and timing for each of these issues was developed by PFM taking into 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 $440.0 million between FY15 and FY20, as indicated on Line 4 of Table 4-8. A portion of the total CIRP expenditures reflects associated internal labor costs (line 12 in Table 4-7 and line 5 in Table 4-8). This cost is also expected to be covered by annual PAYGO revenues. In total, cash financing is expected to fund 26.3% of the total CIRP between FY15 and FY20. The District anticipates receiving grants and contributions of $3.5 million between FY15 and FY20. These sources are expected to fund various improvement projects scheduled to be constructed during the proposed rate cycle. The majority of Line 7 of Table 4-8 represents a capital contribution from the City of Arnold (Arnold) as repayment of a District loan to fund the share of the capacity provided by the Lower Meramec River Regional Wastewater Treatment Plant which started operation in Interest earnings are projected to yield an average 0.5% in annual interest income from FY15 to FY20. Line 8 of Table 4-8 provides the estimated interest income earned on all available CIRP fund balances. Total revenues obtained from grants, contributions, and interest income along with use of fund balance will provide approximately 4.7% of the total CIRP funding Existing and Projected Wastewater Debt The District issued its first District-wide revenue bonds in April Additional senior revenue bonds have been issued in 2006, 2008, 2010, 2011, 2012, and The principal remaining on all of the District s senior revenue bonds issued to date is $740.7 million as of December 31, 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 of the District s SRF Loans issued to date is approximately $315.4 million as of December 31,

39 SECTION 4 PROPOSED WASTEWATER RATES Figure 4-4 Outstanding and Projected Debt Principal WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The projected amortization of future revenue bond issues has been determinedd by PFM and is based on current market conditions and certain assumptions regarding future market conditions. Generally, future senior revenuee bonds are assumed to have a 30-year term and annual coupon rates between 5.0% and 5.5%. Future SRF loans issued d to fund the CIRP program are expected to have 20-year terms and a net effective annual interest t and administration cost of about 3% per year. In addition to the interest cost of future debt, the District will incur issuance costs with each senior revenue bond issue and SRF loan, and be requiredd to maintain a debt service reservee fund for the senior revenue bonds. 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. A Debt Service Reserve Fund is established in an amount equal to the lesser of (1) the maximumm amount of principal of and interest due in any MSD fiscal year on all outstanding senior revenue bonds, (2) 125% of the average annuall debt service on outstanding senior revenue bonds, or (3) an amount not in excess of f 10% of the par value of the outstanding senior revenue bonds. 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 $65.55 million in FY15 to $ million in FY20 as indicated by Table

The District has a minimumm operating reserve target equal to 60 days of annual operating expenses. The existing revenue bond covenants requiree the District to maintain a minimumm 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, provide 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 balance in the WW operating reserve throughout the forecast period. Figure 4-5 Wastewater Operating Reserve 4-19

41 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 4.8 Summary of Wastewat ter Revenue and Revenue Requirements WW revenues must be at least sufficient to finance the WW utility s O&M expense, routine annual capital improvements and debt service costs onn 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. Figure 4-6 Wastewater Financial Plan 4-20

42 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 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 Line 1 of Table 4-10 shows projected WW user charge revenue that is required in order to balance the revenue requirements through FY20. 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.

44 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL In addition to the WW revenue generated from WW user charges, other revenue identified in line 2 through 4 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 $286.5 million in FY15 and increase to $459.1 million in FY20, as shown by line 6 of Table This represents an overall annual compound increase of 9.6% during this time period. The WW utility s O&M expenses, previously introduced in Table 4-6, are shown on line 7 of Table Line 8 of Table 4-10 shows the estimated net revenue remaining after deducting WW O&M expenses from total WW revenues (line 6 minus line 7). Anticipated debt service requirements on senior revenue bonds and SRF loans are presented on lines 9 through 15, 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 $900 million before the start of FY18. Sewer service charge revenue used to finance a portion of the major capital improvement program are reported as a cost on line 16. Line 17 shows the non-recurring projects and studies, as previously presented on Table 4-7, line 11, which are completely financed by annual revenues. Operating reserve deposits required to maintain the minimum balance in the WW operating reserve are shown in line 18. Since the balance is projected to exceed the minimum, no planned contributions to the fund are included. The total annual surplus or deficit is presented in line 21. 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 22 and 23. 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 27 shows the debt service coverage of the senior revenue bond debt service, i.e., the ratio of net revenue (line 8) to total senior revenue bond debt service (line 24) 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 8) to total debt service (line 26) 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 senior debt service coverage fell below the 2.4x to 2.9x range and projected total debt coverage fell below the 1.6x to 1.8x range. The Rate Proposal is designed to maintain a senior debt service coverage ratio of at least 2.50x over the Rate Proposal period. 4-23

45 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 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 Study 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. FY17 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 FY18 through FY20, across-the-board rate increases have been applied to the base service and volume charges with the understanding that the test year is representative of operating conditions for the next few years. Compliance charges and high strength surcharges are projected to increase consistent with future operating cost increases. The cost of service process begins with the total District expenditures for the test year, and these costs are allocated between the two distinct services provided by the District: WW and SW. As is necessary, the SW costs are presented throughout this section but have been segregated and are kept off to the side while performing the cost allocations for the WW system. Once separated from the SW costs, the 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 a portion of them to SW services. The allocation of costs to functions and customer classes primarily centers around the WW system and the SW cost recovery is discussed in greater detail in Section

47 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL Cost Allocations As mentioned previously, the test year for performing the cost of service analysis is FY17. 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 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 FY17 plant investment consists of assets in service as of June 30, 2016, and the estimated costs of proposed capital improvements to be placed in service through the FY17 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 $2.84 billion in FY17. 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 $373.9 million with operating expenses equal to $197.1 million and capital costs equal to $176.8 million, as shown in Table The allocations of these costs to each functional category are also shown in Table 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. 4-26

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 (BOD) and total suspended solids (TSS) related costs. The District also monitors chemical oxygen demand (COD) at the treatment plant and for certain high strength 4-27

49 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL customers. Since historic data has 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. - SW Costs are those operating and capital costs that will be incurred to deliver the increased service level for the SW utility beginning in FY17. Other operating and non-operating revenues are used to offset the allocated costs of service and are therefore deducted from total test year revenue requirements at this point. The net results of the cost classification are presented in Table Additional detail behind specific allocation factors and support can be found in the electronic rate model.

District operations and engineering staff have developed an estimated level of service that has been used in preparing the allocations. The supporting information is presented in Appendix A summary of the costs of service is shown in Table 4-14 which shows approximately 92% of total costs are allocable to the WW utility. The multiple step, base-extra capacity COS allocation methodology that is used to develop these cost allocations is built on and consistent with industry-accepted standards. The allocation of costs used to develop the financial plan (Table 4-10) is performed more holistically as general cost sharing between utility services. While the financial plan has been linked to the cost of service results, these different processes may result in slightly different costs recovered from each utility. The recommended rates comply with cost of service principles and equitably recover revenues as outlined in the cost of service. 4-29

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 in excess of the normal WW strength thresholds, which are contributed by a portion of the nonresidential 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 4-15 for FY17. Annual contributed WW 4-30

52 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 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 indoor water usage attributes. Billable WW volume for metered residential customers is based on water usage during the best equated period, and billable WW volume for all non-residential customers is based on actual 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. District-wide I/I is approximately 50% of the total WW flow reaching the treatment plants on an annual basis. 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 on the basis of the number of customers within each class, with the remaining 60% allocated on the basis of contributed WW volume. These percentages are based on independent engineering studies completed in January 2005 by CDM and presented in the February 2007 WW and SW Rate Proposal. The results of this study were reviewed and are still considered reasonable. The responsibility for collection system capacity related costs varies with the peak flow of both contributed WW and infiltration/inflow attributable to each customer class. Contributed flows are estimated to have a peak to average flow ratio of 1.21 times, while the I/I is estimated to have a peak to average flow ratio of 3.72 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 average influent strength of WW is 100 milligrams per liter (mg/l) for BOD and 170 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 275 mg/l for BOD and 200 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. 4-31

53 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 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 eighty-five Tier 1 customers.

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 Existing Wastewater Rates The existing schedule of rates for WW service shown in Table 4-1 became effective on July 1, The rates consist of monthly service charges, a uniform 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 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 only applicable to non-residential customers.

58 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 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 2,200 customer accounts or 0.61% of the District s total number of single family andd 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 Figure 4-8 Customer Assistance Program Participants Table 4-20 CAP Poverty Guidelines Persons in Family HHS Poverty Guidelines 1 $ 11,670 2 $ 15,730 3 $ 19,790 4 $ 23,850 5 $ 27,910 6 $ 31,970 7 $ 36,030 8 $ 40,090 For each additional $ 4,060 person, add Annual 200% (CAP Eligible) $ 23,340 $ 31,460 $ 39,580 $ 47,700 $ 55,820 $ 63,940 $ 72,060 $ 80,180 $ 8,120 Annual 250% (CAP Eligible Elderly) $ 29,175 $ 39,325 $ 49,475 $ 59,625 $ 69,775 $ 79,925 $ 90,075 $ 100,225 $ 10,

59 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The first CAP rate was adopted by the Board of Trustees in 1993 by Ordinance 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 65 or older. Table 4-20 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 recently expanded the eligibility criteria to 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 The cost impact of the District s current CAP program on a typical single family residential customer not eligible for assistance and discharging 7 Ccf per month of WW is expected to be about $0.18, or 0.42% per month of the District s FY16 WW service charge revenue. This impact is calculated by dividing the revenue reduction associated by the CAP proposed WW rates by the general WW service volume. The impact of the change in eligibility requirements is expected to increase participation in subsequent years as the District continues to actively promote this program and increase the number of qualified low-income customers Excess Strength Wastewater Surcharges The proposed WW volume charges shown in Table 4-19 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 lines 15-17, of Table 4-19 and are expressed on a cost per ton basis Compliance Charge Costs incurred by the District to monitor the quality of WW volume from non-residential customers had historically been recovered by a single monthly compliance charge applied uniformly to all non-residential customers. To provide greater cost recovery equity, a 5-tier structure of compliance charges was implemented as part of the last Rate Commission and 4-38

60 SECTION 4 PROPOSED WASTEWATER RATES WASTEWATER & STORMWATER RATE CHANGE PROPOSAL adopted by the Board in 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 Tier 1 non-residential customers currently pay $9.00 per month, and the approved charge for FY16 is $2.15 per month. Under the Proposed rates this charge increases to $2.86 per month in FY Wastewater Revenue under Proposed Rates A comparison of allocated cost of service results for FY17 with WW revenue under the existing rates is shown in Table 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 4-21 presents a comparison under the recommended rates to the allocated costs of service. 4-39

If voters reject the District s proposed revenue bond authorization, the District will be forced 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 section were used to reflect the impact of rates without the benefits of additional bond authorization. This is a worst-case scenario and has only been developed for comparison purposes. The alternative rates also finance the entire CIRP previously presented by Table 4-7. The resulting rate components change to those shown in Table This change results in an 9.8% increase in the FY17 average single family residential monthly bill, a 65.0% increase in FY18, a 13.1% increases in FY19 and a 15.0% increase in FY20. The typical single family customer bill throughout the Rate Proposal timeframe is presented in Figure 4-9 and shows the impact of not using debt financing for the CIRP beyond what has already been authorized. 4-40

66 SECTION 5 Proposed Stormwater Funding WASTEWATER & STORMWATER RATE CHANGE PROPOSAL PROPOSED STORMWATER FUNDING MSD proposes the use of a District-wide tax structure to replace the multi-layered taxes now assessed on the real estate value of its customers property. This proposed funding is designed to cover the cost of SW maintenance services, capital projects and associated O&M. This section provides the basis for the District s SW component of its Rate Proposal, its underlying assumptions, proposed tax structure and impact on MSD customers. Additional details supporting the assumptions may be found in Appendices 7.5 and History SW is generated when rain or snowmelt is not able to be absorbed into the ground because it falls on a hard or impervious surface, the ground is already saturated or it rains faster than the water can be absorbed. This excess water flows over the ground and then into SW inlets, sewers or directly to local ponds and streams. Unlike WW or combined sewers, SW sewers do not connect to the WW treatment plants (WWTP). Anything that is picked up by SW including trash, pesticides, pet waste, etc., as it flows over yards, streets, and parking lots will make its way into nearby lakes, creeks, and rivers. As of 2013, MSD owns and maintains approximately 3,028 miles of SW sewers and force mains, but does not own or maintain lakes and creeks. MSD is involved in helping the St. Louis region to curb water pollution by partnering with 58 municipalities (co-permittees) and St. Louis County to comply with SW permit requirements for the St. Louis Metropolitan Small Municipal Separate Storm Sewer System (MS4). Likewise, MSD actively works to reduce pollutants that SW picks up and carries into local bodies of water through the St. Louis County Phase II SW Management Plan. MSD maintains public storm sewers, plans and designs improvements to SW infrastructure, regulates SW drainage and floodplain impact related to development projects, and helps coordinate regional efforts to address pollution carried in or caused by SW runoff. 5.2 Existing Stormwater Rates and Taxes District SW revenue is now derived principally from ad valorem taxes. Other sources of income include a flat fee, interest earnings, late charges and other operating income. Existing SW rates and taxes levied by the District are presented in Table 5-1. On March 8, 1988 a majority of the voters approved SW service charges To be collected only in those areas within the boundaries of The where the District has assumed or may in the future assume responsibility for O&M of stormwater and drainage facilities, which election was called pursuant to Ordinance No. 7358, adopted December 23, In addition, flat rate charges of

67 SECTION 5 Proposed Stormwater Funding WASTEWATER & STORMWATER RATE CHANGE PROPOSAL cents per month for residential and non-residential properties and.18 cents per unit for multiresidential were also approved. The outcome of William Zweig et al. v. MSD, appeal No. ED96110 (consolidated with Nos. ED96165 and ED96393) has resulted in the District reverting to a system of flat rate SW user charges, which have not increased since their implementation in 1988, and a system of ad valorem taxes that can only support basic SW operations. The current SW charges and taxes provide significantly less revenue than the former impervious area based user charges. The lower revenue levels postpone needed improvements and contribute to a deterioration of the SW system resulting from inadequate maintenance and delayed improvements. Table 5.1 Existing & Proposed Stormwater Charges Type of Charge Current Rate Proposed Rate Regulatory Tax (District-wide per $100 Assessed Value) Stormwater O&M Tax (City and Near County per $100 Assessed Value) $.0197 $.0197 $.0682 $0 OMCI Specific Subdistrict Taxes (per $100 Assessed Value) $ $0.10 $0 Fixed Monthly Charge Multi-Family Residential ($/unit) Fixed Monthly Charge Single Family & Non-Res ($/account) District-wide Stormwater Tax (proposed) (per $100 Assessed Value) $0.18 $0 $0.24 $0 N/A $.1000 SW revenues consist of monthly flat rate user charges and ad valorem taxes for District-wide, SW operating costs as well as other sub-district specific taxes which fund capital projects and O&M work specific to each sub-district s geographic area. The application of SW ad valorem taxes varies by SW service area. All WW customers are charged the flat rate user charges. All property in the MSD service area is charged $ per $100 of assessed value District-wide tax, but only customers within the District s original service area are charged the additional $ SW O&M tax. OMCI taxes are levied for specific areas within the original service area. These dedicated sub-district taxes range from $0.05 to $0.10 per $100 of assessed property value. 5-2

68 SECTION 5 Proposed Stormwater Funding WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The subdivided funding results in varying levels of SW services across the District. Customers paying just the District-wide tax receive only the minimal SW service needed to comply with regulatory requirements. Customers paying both the District-wide and SW O&M tax receive regulatory services and a level of maintenance up to the limits of the revenue generated by these SW taxes. Those customers paying specific OMCI taxes in addition to the District-wide and SW O&M taxes receive the highest level of SW services. This is, however, still substantially below the level needed to provide a comprehensive SW program as previously funded by the impervious area based SW charge that the State Supreme Court determined was in violation of the Hancock Amendment. 5-3

70 SECTION 5 Proposed Stormwater Funding 5.3 Stormwater Revenue Requirements WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The revenue required to provide for the continued, and expanding operations of the District s SW utility must be sufficient to meet its cash requirements for system operation. Revenue requirements include (1) total SW system O&M expenses, including regulatory; (2) expenditures for routine and any major capital improvements; and (3) provision for an adequate operating reserve Stormwater Operation and Maintenance Expense Revenue collected from the existing SW user charge and ad valorem taxes are available to fund SW related O&M expenditures. However, these revenue sources are not sufficient to fund the District s SW operations. Therefore, the majority of SW O&M activities are the result of failures in the existing collection and conveyance system or as a reaction to customer complaints. These activities include removing blockages, open channel cleaning, repair of storm sewer line failures, and limited inlet inspections and cleanings. The specific operating divisions that provide direct service to the SW system are as follows: Collection System Mintert, Sulphur, and Grand Glaize services Facilities, Garages and Shops Operation Support Services (includes Materials Management, Customer Care and Administration) SW Pump Stations The FY15 adopted budget is the basis for projecting existing SW O&M expenses and is adjusted for the same inflation and growth factors as WW. Table 5-2 shows FY15 SW O&M expenses to be $15.0 million. In FY17, the District plans to expand SW service levels in order to meet the needs of the community. District staff from the engineering and operations divisions have developed a comprehensive estimate for what this level of service will be, including estimated number of maintenance and field crews, capital and construction needs, personnel additions, etc. The total costs also include an appropriate portion of District services that are shared between WW and SW. These costs include things such as the administration, human resources, and finance department costs. Additionally, as part of accounting for SW O&M, a charge for materials and vehicle use is passed on to the SW utility from the WW utility to offset the cost of supplies and routine capital expenditures made by the WW system. The costs just described appear in Table 5-2, line 12. A comprehensive discussion of this level of service is provided in Appendix

71 SECTION 5 Proposed Stormwater Funding WASTEWATER & STORMWATER RATE CHANGE PROPOSAL The total operating costs in FY17 are estimated to be approximately $20.7 million. A projection of the SW O&M costs is presented in Table 5-2 below.

The first are capital projects within the OMCI sub-districts to complete the investments that those customers have supported through their specific taxes. The second are infrastructure rehabilitation projects that will be performed throughout the District and will be funded with a new, proposed District-wide tax for SW (this is discussed in Section 5.4). The estimated level of SW CIRP needs is presented in Figure 5-2, and a list of SW CIRP is in Appendix

72 SECTION 5 Proposed Stormwater Funding Figure 5-2 Stormwater CIRP Needs WASTEWATER & STORMWATER RATE CHANGE PROPOSAL Stormwater Regulatory Services MSD has certain regulatory obligations it must comply with to meet stormwater quality requirements outlined by Missouri Department of Natural Resources. The District is a co-permittee in a State-issued Municipal Separate Storm Sewer System (MS4) permit. Under this permit, MSD must implement Best Management Practicies to address stormwater quality issues. MSD is required to have a public education and outreach program, an illicit discharge detection and elimination program, and a stormwater 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 stormwater runoff from development projects both during and afterr construction is complete. The District- funding to meet our current regulatory obligations. Under the new tax structure and Rate wide ad valorem tax of $.0197 per $100 Assessed Valuee levied by the District provides adequate Proposal, this tax will remain in place to maintain these services Operating Reserve The SW operating reserve is designed to addd a layer of protection for unplanned expenses. Under the proposed funding mechanism, SW revenues will be 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 and capital expenses in the first 6 months of a fiscal year 5-7

74 SECTION 5 Proposed Stormwater Funding 5.4 Proposed Funding Methods WASTEWATER & STORMWATER RATE CHANGE PROPOSAL Meeting the proposed increased level of SW service beginning in FY17 requires that the District develop a more equitable and consolidated SW charge. The District is proposing, and will seek voter approval, to assess a District-wide SW tax to replace the current SW O&M Tax and flat rate charges. The proposed District-wide tax rate is $0.10 per $100 of assessed property value. The subdistrict specific OMCI taxes will be eliminated as part of this Rate Proposal as well; however, the regulatory tax will remain in place. Charging this new SW District-wide Tax will provide the District with the necessary funding to meet the operating requirements of the expanded service levels. Additionally, this proposed structure will eliminate the disjointed revenue sources and provide a funding source that allows for a cohesive plan across the entire District. A summary of SW revenues under existing and proposed rates and taxes is presented in Table 5-3 for the period FY15 through FY20. The SW tax revenues shown in Table 5-3 are developed from detailed records provided by District staff. Projected SW tax revenues shown in Table 5-3 through FY16 are based on staff projections developed for the District s FY15 budget. This budget was approved on June 11, Table 5-1 also presents the proposed new SW Tax which will be assessed to all customers of the District.

The increased level of service can be seen from the increased revenue in FY17 O&M expense (line 14), is a summary of the detailed amounts presented in Table 5-2 and shows the portion of operations that are tied directly to regulatory requirements. Line 15 is the amount of cash financing available for major SW capital improvements which are planned to begin in FY17. The OMCI Capital Projects on line 18 have been identified by the engineering department for each of the subdistricts and will be completed to fully utilize the investments made by each jurisdiction. Line 23 presents the net annual surplus or deficit by the SW operating revenues. The negative balance in FY16 through FY20 represent use of existing fund balances to cash finance the OMCI and District capital needs. Capital spending in the OMCI funds will be $23.9 million from FY17 through FY20. During this same time period, capital spending in the SW O&M Fund and the proposed District-wide SW Fund is projected to be $46.9 million. Capital funding in the District-wide SW fund is made up of $.012 of the proposed $.10 per $100 assessed value tax levy. The declining operating reserve balance is presented in lines and this is being reduced to fund SW activities while maintaining the District s 240 day target balance for the SW operating reserve.

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 very close to the billable volume of a typical metered residential customer. Table 6-3 presents sample unmetered bill impacts. The WW bill for a typical unmetered residential customer contributing 7.7 Ccf of WW each month would increase by $17.86 from FY16 to FY20, or by approximately 9.1% each year. 6-3

82 SECTION 6 Customer Rate Impacts WASTEWATER & STORMWATER RATE CHANGE PROPOSAL 6.3 Stormwater Impacts by Location and Customer Class Table 6-4 below presents a comparison of the current and proposed tax burden by location and by customer class. The impact to customers varies by location due to the varied tax rates described previously in Section 5.2. District-wide, the average single/multi-family annual tax burden would increase $7.50, while the average low income customer participating in our CAP would see an annual decrease of $2.06 and the average non-residential customer would see an annual increase of $ Customers in the City of St. Louis and near St. Louis County (the original boundary area) would see an increase to their overall tax bill of 0.3% on average. Customers in the OMCI area would see a decrease in their total annual tax bill of approximately 0.6% from the changes proposed in this document, while those customers in the Annexed area would see a 1.0% to 1.2% increase on average in their total annual tax burden.

88 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 rate model uses inflation rates for operating and maintenance expenses as well as the construction, improvement, and replacement program (CIRP) expenses. William T. Gavin, Vice President and Review Editor, at the Federal Reserve Bank of St. Louis was consulted in determining what inflation assumptions to use in the rate model. Mr. Gavin reviewed a sample of the District s historical pricing data and determined that analysis of District specific information was unnecessary. Mr. Gavin stated that, in general, a 2% inflation rate for goods and services was a reasonable assumption. In support of this statement, he referred the District to multiple indices published by Federal Reserve Banks, the Social Security Administration, and the Congressional Budget Office to name a few. After performing a review of the recommended sources, the District chose to use The Budget and Economic Outlook: 2014 to 2024 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 February of 2014, this document provided a 10 year forecast that best matched the District s rate model time horizon. Additionally, Table G 1 in this publication presented the Core PCE Price Index (excluding food and energy) which closely matched the 2% inflation rate recommended by Mr. Gavin. It is that index which was used in the model for most expenses. In that same table, a Consumer Price Index reported numbers slightly higher than 2%. 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. Also on Table G 1, was an Employment Cost Index. This index was used as the basis for projected salary increases ranging from 2.9% to 3.2% over the 8 year period ending June 30, Adjustments were made to the CBO projections to account for regional differences, State and local government differences to private industry, and to remove benefits. Each of these adjustments served to lower the projected rate increases published by the CBO. Group insurance was inflated at rates ranging from 8% to 10% based on projections provided by the District s insurance consultant, Arthur J. Gallagher & Company.

92 Customer Growth Overall, the MSD Customer base is projected to experience a decline over the coming years in the Residential and Commercial sectors (1.35% by 2025). Based upon the general population movement within the City and County of St. Louis, the Residential sector is projected to experience a larger decline for Residential and Multi Family Metered customers (1.23%) than their unmetered counterparts (0.24%). The Commercial sector is projected to experience the greatest decline of any account type by 2025 (6.41%) as the downward trend experienced within the past few years is expected to continue. This overall movement of the customer base is projected to have a direct impact on the projected usage as would with any shift in usage patterns occurring within the customer base. Analysis Summary Data Used Calculation Basis (Approach) Customer Growth Overall, the MSD Customer Base is projected to experience a small decline of 1.35% by 2025 (Graph 1.1). Analysis of customer growth in the Residential sector was rooted within the projected population movement data of the entire City and County of St. Louis as provided by State and National Governments. Leveraging the general movement of the population within the City and County, a proportionate movement factor was applied to the MSD customer base to create projections. To provide greater accuracy, projections were calculated based upon the specific account types and appropriate mathematical factors were applied. Specifically, Residential and Multi Family metered accounts are projected to decline by 1.23%, Residential and Multi Family unmetered accounts are projected to decline by 0.24%. Commercial accounts were projected using recent trends within the commercial sector and are projected to decrease by 6.41% by Missouri Department of Corrections, 1994, Institutional Admission and Release Reports.

The data provided by the Government was structured in 5 year increments and by age groupings. The 5 year data was mathematically split into a year over year increments and then used to create a year over year movement factor which was applied to the entire MSD customer base (using yearend FY14 account numbers from the ecis system) based upon the specific account types to create customer projections through Specifically, metered Residential and Multi Family customer projections were calculated using the population movement factor within the City and County combined. Unmetered Residential and Multi Family customer projections were calculated using the population movement within the city. The unmetered accounts used the city movement factor due to the fact nearly all unmetered customers reside within the City of St. Louis. Commercial account projections were calculated using historical values across all tiers of Commercial accounts (COM1 COM5) for FY11 FY13. The year over year change in accounts was averaged across the 3 year timeframe to create a commercial movement factor. The movement factor was applied to the yearend FY13 commercial accounts data to create projections through 2025.

95 Customer Usage Two primary drivers of customer usage were accounted for and analyzed, the overall movement of the MSD customer base (calculated within the Customer Growth appendix) and shifts in usage patterns occurring within the customer base. To quantify shifts in usage within the customer base, changes in usage patterns within the customer population were analyzed to create a complete picture for the usage projections. Results showed the makeup of the non commercial customer base is projected to shift in the coming years as a larger proportion of customers will be comprised of younger generations who show to be more conscientious about their water conservation efforts. With a greater percentage of the customer base conserving more and projected slight reduction in the overall number of MSD customers, overall usage is expected to decline 6.68% by Specifically, the Residential sector is expected to decline by 2.91% and similar to the Commercial sector Customer Growth, Commercial usage is projected to continue a steady decline of 11.46% by Analysis Summary Data Used Calculation Basis (Approach) Customer Usage Across all MSD metered accounts the projected usage is expected to decline by 6.68% by the year 2025 (Graph 1.1) based upon several factors. For Residential and Multi Family metered accounts usage projections were created through a two step process. The first step of the usage analysis leveraged the customer growth analysis data to see how the MSD customer base movement would impact usage (i.e. fewer customers leading to decreased usage or more customers leading to increased usage). The second step of the analysis projected consumption by means of usage profiles as determined by Generational segmentation. Accounts were tagged as a specific Generation (Gen X, Gen Y, Baby Boomers, etc.) and an associated average consumption by generational group was created (Graph 1.2). Yearover year movement within each generational group was calculated (i.e. to what extent each Generational group is growing/shrinking), applied to the group average consumption and summed to determine overall projected usage. Combining these two factors (customer base movement and generational grouping consumption movement) was used to determine the overall change in consumption by identifying to what extent the overall MSD customer base numbers would grow/shrink and how usage patterns within the customer base will change. The overall Customer Usage projections, like the Customer Growth projections, were broken down and calculated based upon account type.

The generational usage segmentation piece of the analysis started with customer account tagging. Each customer account was tagged through the process of adjoining the Experian demographic data with the ecis customer account data to identify the age of the head of the household per account, allowing each account to be segmented into Generational groupings. Once generationally grouped, the average consumption for each Generation was calculated using the billing data from the ecis system. Next, the population movement by age data from the Census Bureau was overlaid on the generational groupings to identify the amount of growth/shrinkage occurring within each of the generation groupings for each year (subset shown in Graph 1.3). The percentage of the population represented by each generation was applied to their associated average consumption to create an overall weighted average consumption each year for all customers. The year to year movement provided a consumption movement factor based upon how consumption is projected to change within the population. The overall customer base movement factor along with the generational based consumption movement factor were combined and applied to yearend 2014 usage numbers from the ecis system to create the overall usage projections for

99 Metered/Unmetered Customer Comparison To be able to correctly compare metered to unmetered customers required calculation of an unknown variable, unmetered customer usage. To try and provide a usage estimate for these unmetered customers, a mathematical decomposition of the current basis for rates formula, which calculates billing based upon rooms, baths, etc., was completed to provide such an estimate for these customers based upon how they are currently being billed. Using this approach it was estimated the average usage for unmetered customers was 7.7 CCFs, which is higher than the known usage for metered customers at 6.3 CCFs. Understanding unmetered usage could easily be higher than, but not necessarily as high, as the estimated billed usage of 7.7, a second analysis was completed to estimate usage for unmetered customers. The second analysis was based upon demographic attributes of the customer account and leveraged attributes of the customer such as age, # of people in the household, region, etc. to determine an estimated average usage. Results of this analysis showed an average usage of 6.9 CCFs, roughly 10% higher than metered customer usage and nearly 10% lower than estimated unmetered usage by billing. Analysis Summary Data Used Calculation Basis (Approach) Metered vs. Unmetered The metered vs. unmetered analysis targeted the identification of estimated usage for unmetered customers to see how it compared with the known usage of the metered customers. Since usage is known for metered customers, the average CCFs was pulled from the billing system data (6.3 CCFs) to create a baseline for comparison against the unmetered customers. In order to create the comparison there had to be a CCF estimate calculated for their unmetered counterparts. To do this, estimated usage for unmetered customers was calculated through a reverse engineering approach to the current basis of rates for unmetered customers formula (based upon # of rooms, water closets, bath/showers) in tandem with account information data that provided the # of rooms, baths, etc. for unmetered accounts. The billing based analysis estimated usage for unmetered customers at 7.7CCFs. Understanding the above estimate is based upon billing and that it s unlikely the unmetered customer s usage is exactly the same as the metered customer s at 6.3 CCFs, an additional analysis was completed based upon demographic attributes of each customer to determine an estimated usage. This analysis targeted the various demographic characteristics of the people within the property to determine their estimated usage. The results from the analysis estimated an average usage of 6.9 CCFs for unmetered customers, roughly 10% lower than the Current Basis of Rates estimated usage (7.7 CCFs) and 11% above known metered customer average usage of 6.3 CCFs (Graph 1.1). While the imputed usage is only slightly higher, the variance between billed amounts shows a greater discrepancy, approximately 29% higher for Unmetered customers (Graph 1.2). ecis customer account data (account #, premise #, address, lat/long etc.) ecis customer billing data (usage, bill amount etc.) Experian Enrichment Summary report including a wide variety of demographic variables (the INSOURCE Database contains coverage on approximately 235 million consumers in 113 million living units with more than 2,500 data elements, INSOURCE encompasses a wide range of consumer information). A data pull from the ecis billing system was used to sum then average the usage for metered customers. The estimated usage analyses completed for the unmetered customers had two different approaches. The first analysis leveraged the current MSD Basis of Rates for the unmetered customers formula (Image 1.1), which calculates usage based upon the number of rooms ( CCFs per), water closets ( CCFs per), and baths/showers ( CCFs per). The total number of rooms, water closets, and bath/showers were summed for all unmetered customers from the ecis system and multiplied by their corresponding CCF rate calculation to create a total estimated usage for all unmetered customers. This aggregate usage was then divided amongst the total number of unmetered customers to create a per unmetered customer estimated average usage. The second analysis calculated estimated usage for unmetered accounts using a statistical method referred to as Multiple Imputation of Chained Equations (MICE). Whereas most statistical procedures exclude observations with any missing values from the analysis, the MICE algorithm replaces each missing value (usage) with a set of plausible values that represent the uncertainty about the right value to impute. The multiple imputed data sets are then analyzed by using standard procedures for complete data and combining the results from these analyses. The result in this analysis being the known variables (various

103 Capital Improvement and Replacement Program (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. As well, projects include reinvestment in the area s wastewater treatment and pump station facilities to ensure operating permit compliance, sustainability, and the continued, proper operation of these industrial facilities. Where economically beneficial, a number of sustainability projects are included to keep MSD cost competitive and efficient. A minimal amount of stormwater projects are included, as well, located in those areas where taxing districts exist to pay for such work. 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 dollars. 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 budget supplement, which details the capital program anticipated for the next fiscal year. For large or multi year projects, budgeting incorporate a phasing approach, such 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.

104 To initiate the CIRP budget preparation, Engineering provides Finance with a project list, including estimated 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 1 was the source for inflation assumptions related to the CIRP. They provide, on their website, a city construction cost index for their subscribers. The average annual construction inflation rate for the 12 months ended August 31, 2014, in the St. Louis area is 2.5%. That rate was employed in the rate modeling process to annually inflate project cost estimates from fiscal year dollars. The second adjustment performed on the CIRP 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 the two most recent years averaged 86% of the annual budgeted appropriations. Using this 86% factor, an appropriation delay was introduced into the numbers. The inflated costs for any given year were reduced by 14%, and that 14% 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 the appropriation left unspent. We refer to these dollars which are returned to fund balance 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, 8% 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 8% of appropriations three years prior. After inflation, appropriation delays, and liquidations, the resulting wastewater program is valued at $1,493,379,657 over four years. This number is lower than the base projection of $1,505,144,000 by 0.8%. 1

148 Benchmark Metrics from 2013 Water Environment Research Foundation (WERF) Survey of Wastwater Utilities WERF Survey Data MSD Data BENCHMARK DEFINITION UNIT MAX MIN AVERAGE MEDIAN MSD SIGNIFICANCE EMPLOYEE METRICS Employees per 1,000 PE served Employee per mgal of wastewater treated Higher management employees REGULATORY COMPLIANCE Total number of exployees/total population equivelent (PE) served x 1,000 Employees/1, Total number of employees/mgal of wastewater treated daily Employees/mgal Number of full time equivalent employees dedicated to directors, central administation, strategic planning, marketing and communications, legal affairs, environmental management, business development/total number of employees x 100 % Current number of PE served by WWTP Compliance with discharge consents - last complying with discharge consents/total PE calendar year served x 100 % % UTILIZATION AND EFFICIENCY Treatment plant utilization - secondary treatment Energy consumption Population coverage SEWER MAINTENANCE Sewer inspection Sewer cleaning Manhole chamber inspection Average daily volume of wastewater which received secondary treatment/total daily capacity for secondary treatment x 100 % Monthly energy used by the utility/mgal of wastewater treated every month Kwh/mgal 2,614 1,396 2,037 1, Total Population served/total population of the service area x 100 % Length of sewer inspected (miles) last calendar year/total length of sewer (miles) x 100 % Length of sewer (miles) cleaned last calendar year/total length of sewer (miles) x 100 % Total number of manhole chambers inspected last calendar year/total number of manhole chambers x 100 % MSD is leaner than the average or median comparable sewer utility. MSD has only 985 employees where the average utility with a population our size would have over 1300 employees. MSD is also leaner the the average or median comparible sewer utility based on wastewater treated, with an average daily flow of 330 millon gallons a day and 985 employees. The average comparable utility would have over 1600 employees treating flows this large. This measure shows that MSD is not top heavy, with 23 directors, assistant directors, legal and communication and enviornmental management staff. The median utility would employee 33 staff in such positions. MSD has 99.9% compliance with regulatory compliance of treatment plant permits. This is above the industry average and is the expectation of the District. With plant capacity utilization of nearly 75% MSD is not overbuilt and amoung industry leaders. Regulations do not allow utilzation over 80% without expanding. MSD electrical consumption per million gallons shows that usage is among the lowest, or our efficeincy is among the highest(159million kw/yr /292mgd) MSD provides service to nearly all homes within its service area. This helps improve utilization and effiecency MSD inspected 511 miles of the total 6350 miles pipe this is slightly better than average but not excessive MSD cleaned 1371 miles of pipe(928 miles non plastic and 443 miles of plastic) of the 6350 miles of pipe. This meets the Districts goal of cleaning sewers approximately every 5 years. This proactive approach has led to a 70 % reduction in basement backups and 50% reduction in overflows. MSD inspected manholes out of 162,000 or 10.5%. This is in line with the average utility and meets our regulatory requirements. Sewer replaced/rehabilitated last calendar year Length of sewer (miles) replaced or rehabilitated last calendar year/total length of sewer (miles) x 100 % MSD rehabilitated miles of the 6340 miles of pipe. This is nearly 2% of the system and above the goal of 90 miles/yr. The 2% is driven by overflow reduction and removal needs and is not excessive, 1.5% is needed just to rehab sewers on a 67 year cycle.. Sewer blockage last calendar year CUSTOMER CALL Total number of sewer blocks last calendar year/total length of sewer x 100 Number/100 mile MSD had 326 sewer blockages that caused basement backups and/or sewer overflows. This is down from historical levels of 1000/yr. Due to our continued maintenacne efforts our rate of 5 blockages/100 miles of pipe is much lower than the average.

149 Total service inquiries per 1,000 PE served SAFETY Working accidents: Percentage of employees injured last calendar year Total number of inquiries last calendar year/ttotal PE served x 1,000 Number/1000 PE served Number of employees injured on the job last calendar year/total number of employees x 100 % MSD aveages about customer calls per year. This equates to 10 calls per 1000 persons served. This puts us among the higher surveyed, but it is hard to to interpret this number. We don't know if it translates to more problems or better communications. We take both wastewater and stormwater calls Being lean on management does not translate to poor safety. MSD averaged 3.75 lost time injuries per 100 employees in This is about half the average.

151 Date: August 27, 2014 To: From: Janice Zimmerman Audit File Pamela Reid, Interim Accounting Manager Subject: Accounts Receivable Allowance Bad Debt Change During fiscal year 2014, the accounting personnel completed an analysis on the wastewater sewer service charges collection patterns using a new analytical tool. The analysis was based on billings as far back as 1981; however, the account detail moved into the analytical tool was 2006 to present. The collections for wastewater sewer service charges were consistently collected 98% of the time by the fifth year after billed. The billing and collection data was verified to ensure that the information used with the analytical tool was valid. Using a random sample of customer accounts, accounting personnel verified the accuracy. No issues were found in the data. Prior to fiscal year 2015, the allowance for bad debt was calculated using aging buckets and percentages associated with the aging. The aging buckets and their percentages are as follows: Unbilled 2% 1 90 DAYS 5% DAYS 10% DAYS 20% 360+ DAYS 100% Based on the analysis completed, it appeared that recording the allowance at 100% for the wastewater sewer service charges receivable balance for accounts aged at 360 or more was excessive. As of June 30, 2014, MSD will no longer use the buckets to determine the reserve. The new calculation will now use the billed revenue to record the reserve. MSD changed the allowance calculation using 2.15% of the wastewater sewer service billed revenue to correlate with the analytics completed. The data went as far back as 1981 which was included in the database; however, the information relating to 1997 and

152 prior was limited information. The collection trend proved that 98% of the billings were collected within five years. The accounting department reviewed several periods of collections data using numerous combined years. Some examples of the results to make the determination on the rate to use are as follows: Years Billings Collections Rate 1981 to 2014 $2,390,617, % 2.80% 2009 (5 years ago only one year) 222,679, % 2.10% 2008, 2009, ,508, % 2.10% 2006, 2007, 2008, 2009, ,059,434, % 1.70% Based on the above, the District chose to make the adjustment for years 2006 thru June 2014 billing cycle using 2.15% (conservative approach) for the billings on wastewater sewer service charges. In addition, for the years 1981 to 2005, the District chose to record the uncollected balance which was less than the 2.15%. The adjustment of $9,765, was recorded at the end of FY14. This adjustment represents an accumulated estimate recorded in prior years. The revised process to be used starting in FY15 is as follows: 1. Determine the new uncollectible rate for years 2006 thru 5 years from the fiscal year end. 2. Apply the new percentage to billings in the current year. 3. In addition, any items collected relating to 1981 to 2005 will be reduced from the reserve balance. 4. During the months of May and June, the prior year reserve balance would be reviewed and adjusted to ensure the reserve reflects the current collection period. In FY15, the storm service charge will be adjusted using the same process to calculate the reserve balance described above for wastewater sewer charge. This adjustment is planned to be made in December FY15. Metropolitan St Louis Sewer District 2350 Market Street St. Louis, MO (fax)

157 Customer Assistance Program (CAP) Analysis The Customer Assistance Program analysis focused on identifying current MSD customers who qualify for the CAP program based upon predefined eligibility requirements (for both 2014 and 2012) and where these customers are located geographically. Analysis showed that 12.2% of Residential customers qualify for the CAP program based upon the 2014 criteria and only 4.2% would qualify using the 2012 eligibility criteria. The expansion of the income requirements from 2012 to 2014 nearly tripled the amount of qualified customers for CAP program enrollment. When analyzed geographically, the majority of CAP qualified customers reside within the OMCI Region (61%), compared to 32% which live within the City. A geographical overlay of 2014 CAP qualified customers aggregates and maps account location by the premise zip code (Image 1.1) to provide high level geographical view of eligible customers. Analysis Summary Data Used Calculation Basis (Approach) Customer The purpose of the CAP analysis was to use the Experian variables were merged with Assistance predefined criteria to identify Residential MSD ecis customer data based on account, customers who qualify for the CAP Program. The customer, and premise numbers. These Program analysis looked at results for both the 2012 CAP variables included data such as income, (CAP) criteria as well as the current 2014 CAP criteria education, number of persons in (see Tables 1.1 and 1.2 below). household, region, age, gender and many others. Results of this analysis showed that using 2014 CAP criteria, 38,982 customers (12.2%) met either CAP Eligible or CAP Eligible Elderly requirements. More specifically, 30,719 (9.6%) qualified by CAP Eligible requirements and 18,382 (5.7%) qualified by CAP Eligible Elderly requirements. Using 2012 CAP criteria, 13,423 customers (4.2%) met either CAP Eligible or CAP Eligible Elderly requirements. More specifically, 11,193 (3.5%) qualified by CAP Eligible requirements and 5,664 (1.8%) qualified by CAP Eligible Elderly requirements. Regionally it was discovered that 26% of the City region included CAP Eligible, CAP Eligible Elderly, or customers already enrolled in the CAP Program (EA customers). 15% of the OMCI region included CAP Eligible, CAP Eligible Elderly, or EA customers. 3% of the Extension region included CAP Eligible, CAP Eligible Elderly, or EA customers. It was also determined that CAP Eligible, CAP Eligible Elderly, and EA customer head of households are more likely to have a high school diploma as the highest level of education and are likely to have 4 5 persons living in the household. It was noted that as the number of people in the household increased a greater percentage of that customer group were qualified for the CAP program (Graph 1.1). Overall, the Customer Assistance Program analysis helped to identify CAP Eligible or CAP Eligible Elderly customers, understand regionally where they tend to reside, and provide additional demographic information on the characteristics of this group of customers. ecis customer account data (account #, premise #, address, lat/long etc.) ecis customer billing data (usage, bill amount etc.) Experian Enrichment Summary report including a wide variety of demographic variables (the INSOURCE Database contains coverage on approximately 235 million consumers in 113 million living units with more than 2,500 data elements, INSOURCE encompasses a wide range of consumer information). Generational Data ( /2011/05/living/infographic.boom er/) 2012 and 2014 CAP eligibility requirements (see Tables 1.1 and 1.2 below) were utilized to create customer account flags to identify customers who fell into each of the CAP Eligible or CAP Eligible Elderly categories. These identifiers were merged with ecis and Experian customer data. The variables used to create customer account flags included Number of Persons (in household), Median Family Household Income, and Age. Based on the number of persons in the household, if the median family household income is at or below the CAP Eligible criteria, these customers were flagged as CAP Eligible. Based on the number of persons in the household, if the median family household income is at or below the CAP Eligible Elderly criteria AND the age of the head of household was 62 or greater, these customers were flagged as CAP Eligible Elderly. Once these CAP Eligibility identifiers were merged with the overall data, the findings included in the analysis summary were discovered by slicing the data by the various data elements available from the Experian data such as region, household size, etc.
