I testified as the Rate Consultant to the Rate Commission in the 2007, 2008 and 23 2011 Rate Change Proceedings. 24 2015 Rate Change Proceeding 2 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q7. Please describe your role in this proceeding? 1 A. The scope of my assignment in this proceeding is as Project Director for RFC's assistance 2 to the District in preparing the Rate Change Proposal which recommends means of 3 financing MSD's wastewater and stormwater activities for fiscal years ending June 30, 4 2017 (FY17) through June 30, 2020 (FY20). As project Director, I provided leadership 5 and direction to our team of consultants engaged in this work for the District, as well as 6 technical advice during the conduct of our work. 7 8 General Matters 9 Q8. What requirements are you aware of that any proposed changes in wastewater, 10 stormwater or tax rates by the District must meet? 11 A. Pursuant to Section 7.040 of the Charter Plan of the District any proposed changes in 12 wastewater, stormwater or tax rates must be necessary to pay (i) interest and principal 13 due on bonds issued or to be issued to finance assets of the District, (ii) the costs of 14 operation and maintenance, and (iii) such other amounts as may be required to cover 15 emergencies and anticipated delinquencies. 16 Q9. How is it determined whether the District’s Rate Change Proposal is necessary? 17 A. This determination begins with the development of the District’s Comprehensive 18 Financial Plan which is a major component of the rate Change Proposal. As the rate 19 Consultant to the District, our work included the development of this Financial Plan in 20 collaboration with District Staff and the District’s other consultants. The forecasts set 21 forth in the Rate Change Proposal form the foundation of the level of revenues needed to 22 achieve the District’s operational and capital investment objectives. The Rate 23 Commission will examine the District’s projected revenue requirements to insure that 24 2015 Rate Change Proceeding 3 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 such revenue requirements are necessary and reasonable to meet the District’s near term 1 financial needs, that such revenue requirements do not overstate the District’s near term 2 financial needs, and that such revenue requirements are being recovered in a fair and 3 equitable manner. 4 Q10. What criteria are used to assess the Rate Change Proposal? 5 A. In accordance with Section 7.270 of the Charter Plan of the District, the Rate Change 6 Proposal, and all portions thereof, must: 7 (1) be consistent with constitutional, statutory or common law as amended from time to time; 8 (2) enhance the District’s ability to provide sewer and drainage systems and facilities, or 9 related services; 10 (3) be consistent with and not in violation of any covenant or provision relating to any 11 outstanding bonds or indebtedness of the District; 12 (4) not impair the ability of the District to comply with applicable Federal or State laws or 13 regulations as amended from time to time; and 14 (5) impose a fair and reasonable burden on all classes of ratepayers. 15 Q11. How should it be determined if the Rate Change Proposal is consistent with 16 constitutional, statutory or common law as amended from time to time? 17 A. In the past legal counsel has advised that issues concerning Charter Plan authority, 18 environmental laws and regulations, constitutional and statutory provisions and case law 19 should be evaluated. 20 Q12. How should it be determined whether the Rate Change Proposal enhances the 21 District’s ability to provide adequate sewer and drainage systems and facilities, or 22 related services? 23 A. The Rate Change Proposal should be assessed as to whether it enhances the District’s 24 2015 Rate Change Proceeding 4 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 ability to provide adequate sewer and drainage systems and facilities, or related services. 1 This can be done by examining the District’s submittal as well as the testimony filed in 2 support of the Rate Change Proposal by the District, the Rate Commission's Rate 3 Consultant testimony and advice as well as the testimony provided by interveners. 4 Q13. How should it be determined if the Rate Change Proposal is consistent with and not 5 in violation of any covenant or provision relating to any outstanding bonds or 6 indebtedness of the District? 7 A. Such a determination requires an analysis of covenants or provisions contained in the 8 resolutions or ordinances issuing any such outstanding bonds or indebtedness. It may be 9 determined that this condition is met by examining the District’s submittal as well as the 10 testimony filed in support of the Rate Change Proposal by the District. 11 Q14. How should it be determined whether the Rate Change Proposal impairs the ability 12 of the District to comply with applicable Federal or State laws or regulations as 13 amended from time to time? 14 A. It may be evaluated whether the Rate Change Proposal impairs the ability of the District 15 to comply with applicable Federal or State laws or regulations on the basis of testimony 16 provided by District staff and by others, including interveners. 17 Q15. How should it be determined if the Rate Change Proposal imposes a fair and 18 reasonable burden on all classes of ratepayers? 19 A. Whether the rate change imposes a fair and reasonable burden on all classes of ratepayers 20 may be determined by examining the Rate Change Proposal and the testimony filed in 21 support of the District's Rate Change Proposal as well as information provided by the 22 Commission's Rate Consultant, and other parties, including the interveners. 23 24 2015 Rate Change Proceeding 5 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q16. In the context of utility rate setting, what do the words “fair and reasonable” mean 1 to you? 2 A. In the context of utility rate setting, the word “fair” means to me that rates recover 3 revenues from customer classes in relation to the costs incurred in providing utility 4 services to those customer classes and be free from self-interest, prejudice or favoritism. 5 In the context of utility rate setting, the word “reasonable” means to me that the revenue 6 requirements upon which the rates are based reflect an appropriate level of funding to 7 enable the utility to provide adequate and sustainable service and support the financial 8 health of the utility. 9 Q17. Do you believe the Rate Change Proposal meets these criteria? 10 A. Yes. 11 12 Major Wastewater Rate Changes 13 Q18. What are the major wastewater rate changes contained in the Rate Change 14 Proposal? 15 A. For wastewater we are proposing rates in FY17 that reflect the results of the cost of 16 service analysis for that year and which will be discussed later in my testimony. The 17 proposed waster rates for FY18 through FY20 are approximately 10.75%. The resultant 18 impacts vary among the various rate and charges of the District as determined in the cost 19 of service analysis and discussed later in my testimony. Overall the Rate Change 20 Proposal does not contain any changes to the current wastewater rate structure as was the 21 case with the 2012 Rate Change Proposal which included the implementation of a tiered 22 compliance charge. 23 24 2015 Rate Change Proceeding 6 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q19. What are the major drivers of the rate change? 1 A. The largest factor in the requested rate change is the District's CIRP expenditures, which 2 as discussed in the testimony of Richard Unverferth, are driven by the District's Consent 3 Decree requirements. The District intends to fund the CIRP to the extent possible with 4 debt while maintaining coverage requirements that will maintain their existing debt 5 rating, as discussed in the testimony of Tim Snoke and Bethany Pugh. To a lesser extent 6 the rate change is also a result of inflation in the operating and maintenance budget, 7 additional operating and maintenance expense, and a projected decrease in both 8 customers and contributed volumes over the period covered by the Rate Change 9 Proposal. 10 11 Wastewater Revenue 12 Q20. How was wastewater revenue projected in the Rate Change Proposal? 13 A. Projected wastewater revenue is based in part on an analysis performed by The Vertex 14 Group for the District and discussed in Appendices 8.1.2 and 8.1.3 of the Rate Change 15 Proposal that projects number of customers and contributed volumes over the period of 16 FY17 through FY20. The projected number of customers and contributed volumes 17 information is shown in the Rate Change Proposal in Table 5-2, which includes projected 18 accounts by customer class, and Table 5-3, which includes projected contributed volumes 19 by customer class. Based on this information projected revenues under the District’s 20 approved FY16 rates for the period of FY17 through FY20 is shown in Table 5-4 while 21 other revenues for the District are shown in Table 5-5. Table 5-5 was developed in 22 conjunction with District Staff based on past experience and projected trends of each 23 revenue line item. 24 2015 Rate Change Proceeding 7 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q21. Were any other changes made that affect the District's projected revenue? 1 A. The District bills unmetered customers, which consist of most residential customers in 2 the City of St. Louis, using attributes of their property. These attributes are each room, 3 each water closet, each bath and each separate shower. The usage assigned to each 4 attribute was determined several decades previously based on data provided by the City 5 of St. Louis used to bill these customers for their water consumption. It was determined 6 that these attributes and the usage associated with them should be reexamined, and 7 Vertex performed a statistical analysis as described in Appendix 7.1.4 that determined a 8 reduction of usage associated with unmetered customers attributes would be appropriate, 9 and that reduction has been implemented in the proposed FY17 rates in the Rate Change 10 Proposal. 11 Q22. What is your opinion of the forecast of customers and contributed volumes? 12 A. Based on my past experience with the District, my experience with other urban utilities 13 throughout the United States, and general trends in wastewater flows throughout the 14 United States I believe the forecasts are reasonable. 15 16 Wastewater Revenue Requirements 17 Q23. What are the components of the District’s wastewater revenue requirements? 18 A. The District’s wastewater revenue requirements arise from three basic needs, O&M 19 expense, capital expense, and funding of reserves. Capital expense can further be broken 20 down between debt service requirements, which is the payment of debt used to fund 21 capital projects, and use of internally generated funds or cash funded capital, which is 22 also sometimes referred to as PAYGO capital, short for Pay As You Go. 23 24 2015 Rate Change Proceeding 8 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q24. Do the wastewater expenses included any costs that should be allocated to 1 stormwater? 2 A. During the course of the analysis wastewater and stormwater costs are separated. For 3 O&M expense each item in the budget is allocated to wastewater or stormwater based on 4 an analysis of the activities of each department. In total this results in approximately 5 89% of O&M costs being allocated to wastewater and 11% of the O&M costs being 6 allocated to stormwater in FY17. 7 Q25. How are wastewater O&M expenses projected over the period of the Rate Change 8 Proposal? 9 A. The District Finance Staff under the direction of Janice Zimmerman identified 10 appropriate inflation factors for the various items in their budget. Appendix 8.1.1 11 provides a discussion of the major assumptions and how they were determined for 12 inflation. The inflation rates used are shown in the table below. 13 Cost Category FY16 FY17 FY18 FY19 FY20 General Inflation Rate 3.0% 1.9% 1.9% 2.0% 2.0% Personnel 2.8% 3.1% 3.2% 3.1% 3.1% Health Insurance 7.5% 9.5% 8.9% 8.0% 8.1% Dental Insurance 6.8% 2.5% 6.1% 6.1% 6.1% Vision 0.0% 0.0% 0.0% 0.0% 0.0% Pension 3.2% 0.0% 0.0% 0.0% 0.0% Electric 5.5% 5.5% 5.5% 5.5% 5.5% Natural Gas 5.5% 5.5% 5.5% 5.5% 5.5% Other Utilities 3.0% 3.0% 3.0% 3.0% 3.0% Bond & Liability Insurance 5.0% 5.0% 5.0% 5.0% 5.0% Ash Hauling 3.0% 3.0% 3.0% 3.0% 3.0% Applying these inflation rates to the District's adopted FY15 budget results in the 14 projected wastewater O&M expense shown in Table 5-6 of the Rate Change Proposal. In 15 addition the District provided forecasts of additional O&M required beyond inflationary 16 increases, which is shown on Line 22 of Table 5-6. The Capital Funded in the O&M 17 Budget and Capitalized Internal Labor were provided by District Staff. 18 2015 Rate Change Proceeding 9 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q26. How are the District’s wastewater CIRP requirements projected over the period of 1 the Rate Change Proposal? 2 A. The District provided wastewater capital improvement and replacement program (CIRP) 3 requirements to be included in the financial planning and rate model. The figures 4 provided by the District include adjustments for the timing of the actual cash needs as 5 discussed in Appendix 8.1.6. The amount of the CIRP is inflated in FY17 through FY20 6 based on an analysis of regional Engineering News Record construction cost index data. 7 The resultant cash requirements for the CIRP are shown in Table 5-7 of the Rate Change 8 Proposal while additional detail on the District’s overall CIRP can be found in Appendix 9 8.2. 10 Q27. How does the District propose to fund the wastewater CIRP over the period of the 11 Rate Change Proposal? 12 A. The District and its financial advisor, PFM, provided a financing plan for the District’s 13 wastewater CIRP as discussed in the testimony of Bethany Pugh. A summary of the 14 overall mix of debt and cash is shown in Table 5-8 of the Rate Change Proposal. 15 Q28. How are the District’s wastewater debt service requirements determined in the Rate 16 Change Proposal? 17 A. Wastewater debt service requirements for all existing and proposed debt were provided 18 by the District’s financial advisor, PFM as discussed in the testimony of Bethany Pugh. 19 Q29. How are the District’s wastewater reserve requirements determined in the Rate 20 Change Proposal? 21 A. The District has a minimum operating reserve target equal to 60 days of annual operating 22 expenses. The existing revenue bond covenants require the District to maintain a 23 minimum balance equal to 45 days of operation and maintenance expense. The District 24 2015 Rate Change Proceeding 10 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 has determined that it is prudent to target a 60 day minimum which provides a buffer to 1 allow for potential timing issues involved with funding requirements, provide increased 2 operational flexibility, and helps support future bond ratings. 3 4 Wastewater Financial Plan 5 Q30. How are the overall wastewater revenue increases necessary over the Rate Change 6 Proposal period determined? 7 A. Based on the projected revenues under existing rates and the District’s revenue 8 requirements the financial planning and rate model can be used to determine the level of 9 wastewater revenue increases to meet the District’s financial objectives. Based on 10 discussions with District Staff as well as the District’s FA it was determined that the 11 driving factor in determining rate increases is the District’s desire to maintain a Senior 12 Debt Coverage level of 2.5, as discussed in the Testimony of Tim Snoke and Bethany 13 Pugh. Based on this goal and the desire to provide a smooth program of rate increases 14 over the Rate Change Proposal period it was determined that an annual average revenue 15 increase of approximately 10% will be necessary to meet the forecasted revenue 16 requirements. The District’s Wastewater Financial Plan is shown on Table 4-10. As can 17 be seen in Table 4-10 the District’s senior debt coverage level declines to 2.52 in FY20 18 with the proposed revenue increases. 19 20 Wastewater Cost of Service 21 Q31. What is a cost of service analysis? 22 A. The basic principle in a cost of service analysis is to achieve general fairness in the 23 recovery of costs from various classes of customers. The approach used in this Study is 24 2015 Rate Change Proceeding 11 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 based on the principles endorsed by the Water Environment Federation (WEF); which 1 allows the District to demonstrate rates have not been set in an arbitrary manner and one 2 class of customer is not subsidizing another to an unjustifiable extent, or in a manner that 3 is not approved and supported by the District. 4 Q31. What period was analyzed for the cost of service analysis? 5 A. A cost of service analysis typically identifies a single test year to be used as the basis of 6 the analysis. For this analysis the projected expenses for the first year of the Rate Change 7 Proposal period, FY17 are used. It is common for non-regulated utilities to use a 8 projected test year, as compared to regulated utilities which are often required by the 9 applicable regulatory body to use an historical test year with allowances for known and 10 measurable changes. 11 Q32. How are O&M costs assigned or distributed to functions in the cost of service 12 analysis? 13 A. The O&M costs were assigned or distributed to functional categories based on factors 14 developed with available data, District Staff, and generally accepted industry practices, 15 and were then reviewed to ensure the appropriate factors were applied. For example, 16 operating costs for the customer service center were assigned to customer service and 17 billing; costs for operating the treatment plants were assigned to treatment; and collection 18 costs were assigned and distributed between collection and conveyance. General and 19 administrative cost elements are allocated based on the weighted average allocation of the 20 direct costs. A summary of the functionalized O&M costs is shown in Table 4-11 of the 21 Rate Change Proposal. 22 23 24 2015 Rate Change Proceeding 12 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q33. How are capital costs assigned or distributed to functions in the cost of service 1 analysis? 2 A. Capital costs (debt service requirements and rate-funded capital) are assigned or 3 distributed based on an analysis of the District’s fixed assets. The estimated test year 4 FY17 plant investment consists of plant in service as of June 30, 2016, and the estimated 5 costs of proposed capital improvements to be placed in service through the FY17 test 6 year. Total plant investment, on an original cost less accumulated depreciation basis, is 7 assigned to functional cost components reflecting the function of the assets.. Test year 8 plant investment in WW facilities on an original cost less depreciation value basis is 9 projected to total $2.84 billion in FY17. The functionalization of total plant investment is 10 also used as the basis to allocate total routine capital improvements. A summary of the 11 functionalized capital costs is shown in Table 4-11 of the Rate Change Proposal. 12 Q34. How are the functionalized costs then used in the cost of service analysis? 13 A. The functionalized costs are next allocated to their cost components in accordance with 14 how the facilities are designed. In this step of the cost of service process, costs are 15 apportioned to the functional cost drivers of: 16 • Volume - costs related to the volume of wastewater flow received by the wastewater 17 system such as the portion of the collection and conveyance systems necessary to handle 18 average volumes of the wastewater system. 19 • Capacity - costs related to the peak flow of the system, in other words facilities sized not 20 just to meet typical volumes, but peak volumes, including preliminary treatment at the 21 wastewater treatment plants as well as the portion of the collection and conveyance 22 systems necessary to meet peak flows. 23 24 2015 Rate Change Proceeding 13 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 • Compliance - Cost associated with compliance for the District's pretreatment program for 1 commercial customers, specifically a portion of the costs of the Environmental 2 Compliance Division of the Engineering Department. 3 • Wastewater strength - Costs associated with treatment of the strength components of 4 wastewater flow, including primary and secondary treatment at the wastewater treatment 5 plants. 6 • Customer and billing - Costs associated with providing service to customers regardless of 7 their flows or other demands, including customer service and some regulatory services 8 he separation of costs into functional cost components provides a means for distributing 9 such costs to the various cost drivers on the basis of respective responsibilities for each 10 particular type of service. A summary of this analysis is shown in Table 4-12 of the Rate 11 Change Proposal. 12 Q36. How are the costs allocated to customer classes? 13 A. The total cost responsibility for each customer class is determined by developing 14 wastewater system unit costs of service for each cost component and applying these unit 15 costs to the respective service requirements of each customer class. In accomplishing this, 16 each customer class is allocated a share of volume, capacity, strength and customer costs 17 for which it is responsible. 18 The unit cost of service represent the cost of providing a unit of each cost component, 19 volume, capacity, strength, and customer and billing, to each customer regardless of their 20 other characteristics. Each customer class pays the same for each service they receive, 21 though they may receive different amounts of each service, which is the basis for 22 different costs by customer classes. In other words, differences in costs between 23 customers is based on a fair and equitable determination of the cost of providing specific 24 2015 Rate Change Proceeding 14 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 services and those differences in cost are a result in different levels of service and not 1 different pricing for the same service levels. 2 Customers are divided into customer classes that represent a particular type of service 3 requirement or load on the system. The residential customer class includes residents 4 living in single family and multi-family dwellings. The non-residential class includes all 5 customers not included in the residential class such as commercial, government, 6 industrial etc. Wastewater strengths in excess of the normal wastewater strength 7 thresholds, which are contributed by a portion of the non-residential class, are segregated 8 into a separate surcharge customer group. 9 The determination of customer class responsibility for costs of service requires that the 10 customer classes be allocated a portion of the volume, capacity, strength and customer 11 costs of service according to their respective service requirements. Service requirements 12 or units of service for the respective customer classes are shown in Table 5-15 of the Rate 13 Change Proposal. 14 Q36. How is the inflow/infiltration amount determined? 15 A. Infiltration/inflow (I/I) includes flow entering the sewer system from illegal roof and 16 foundation drains, groundwater infiltration through sewer service pipe and main joints 17 and stormwater runoff or inflow from the combined sewer system. We examined and 18 analyzed historic treatment plant and billed consumption data as well as recognizing the 19 District's improvements to the interceptors delivering wastewater to the treatment plants 20 and estimated that District-wide I/I is approximately 50% of the total wastewater flow 21 reaching the treatment plants on an annual basis. This is a decrease in the percentage of 22 I/I and reflects the improvements that the District has made in the interceptors 23 transporting flow to the wastewater treatment plants. 24 2015 Rate Change Proceeding 15 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q38. How is responsibility for I/I determined? 1 Each customer class should bear its proportionate share of the costs associated with I/I, as 2 the WW system must be adequate to convey and process the total wastewater flow. The 3 amount of I/I to be recovered directly from wastewater service charges is assigned to 4 customer classes on the premise that 40 percent of the total is distributed on the basis of 5 the number of customers within each class, with the remaining 60 percent allocated on 6 the basis of contributed wastewater volume. These percentages are based on independent 7 engineering studies completed in January 2005 by CDM and presented in the February 8 2007 Wastewater and Stormwater Rate Change Proposal. The results of this study were 9 reviewed and are still considered reasonable. This reallocation of I/I costs can be seen in 10 Table 5-17 of the Rate Change Proposal. 11 Q39. How do District’s existing rates compare to the cost of service analysis? 12 A. The results of the cost of service analysis are summarized in Table 5-18 and show the 13 amount that each class as a whole is being under-recovered by relative to the District’s 14 revenue requirements for FY17. While there are varying impacts among customer 15 classes, they do not vary significantly from the overall revenue increase of 10.75% which 16 indicates that on the whole there should not be significant differential impacts to 17 customers from the cost of service rate adjustments. 18 19 Wastewater Rate Adjustments 20 Q40. How are the cost of service rate adjustments determined? 21 A. Based on the units costs calculated in the cost of service analysis as shown on Table 5-16 22 of the Rate Change Proposal we can develop proposed rates that are cost of service based 23 and will provide an equitable recovery of costs from the District’s customer classes. 24 2015 Rate Change Proceeding 16 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 These rates are presented in Table 5-19 of the Rate Change Proposal. 1 Q40. Are these proposed rates fair and equitable? 2 A. A comparison of the revenues generated under the proposed rates to the calculated cost of 3 service is shown in Table 4-21 of the Rate Change Proposal, and as is indicated by the 4 percent difference in the far right column, the proposed rates over- or under-recover the 5 allocated costs of each customer class by a relatively small amount, which is a strong 6 indication that they will yield a fair and equitable recovery of the District’s revenue 7 requirements from the various customer classes. 8 9 Major Stormwater Rate Changes 10 Q42. What are the major stormwater rate changes contained in the Rate Change 11 Proposal? 12 A. The Rate Change Proposal includes changes in the property tax levies charged by the 13 District, eliminating the differential rates charged to various properties across the District 14 and replacing them with a more uniform structure of tax levies. This details of this 15 change are discussed in the testimony of Brian Hoelscher. 16 17 Stormwater Revenue 18 Q43. How was stormwater revenue determined? 19 A. We worked with District Staff to analyze billing data, tax information, and other revenue 20 data to determine the amount of stormwater revenue generated under existing tax rates as 21 well as projected revenue under proposed tax rates. A summary of the stormwater 22 revenues is shown in Table 6-3 of the Rate Change Proposal. 23 24 2015 Rate Change Proceeding 17 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Stormwater Revenue Requirements 1 Q44. What are the components of the District’s stormwater revenue requirements? 2 A. The District’s stormwater revenue requirements arise from three basic needs, O&M 3 expense, capital expense, and funding of reserves. Unlike the wastewater revenue 4 requirements, stormwater does not have any debt outstanding nor does the District intend 5 to issue any debt, so the capital expense revenue requirements arise only from capital 6 projects funded from cash (i.e., PAYGO). 7 Q45. How are stormwater O&M expenses projected over the period of the Rate Change 8 Proposal? 9 A. The District identified appropriate inflation factors for the various items in their budget, 10 as discussed in Appendix 8.1.1 as well as my answer to Question 23, which results in the 11 projected stormwater O&M expense shown in Table 6-2 of the Rate Change Proposal. In 12 addition the District provided forecasts of additional O&M required beyond inflationary 13 increases, which is shown on Line 23 of Table 6-2. The Capital Funded in the O&M 14 Budget and Capitalized Internal Labor were provided by District Staff. 15 Q46. How are the District’s stormwater CIRP requirements projected over the period of 16 the Rate Change Proposal? 17 A. The District provided stormwater capital improvement and replacement program (CIRP) 18 requirements to be included in the financial planning and rate model. The figures 19 provided by the District include adjustments for the timing of the actual cash needs as 20 discussed in Appendix 8.1.6. The amount of the CIRP is inflated in FY17 through FY20 21 based on an analysis of regional Engineering News Record construction cost index data. 22 A summary of the resultant cash requirements for the CIRP are shown in Figure 6-2. 23 24 2015 Rate Change Proceeding 18 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 Q47. How does the District propose to fund the stormwater CIRP over the period of the 1 Rate Change Proposal? 2 A. The District will fund the stormwater CIRP from cash generated through stormwater fees 3 and taxes. The District has indicated to me that they do not intend to issue debt to 4 finance the stormwater CIRP. 5 Q48. How are the District’s stormwater reserve requirements determined in the Rate 6 Change Proposal? 7 A. The District has a minimum operating reserve target equal to 240 days of annual 8 operating expenses. The 240 day minimum provides a buffer to allow for the timing of 9 tax receipts relative to its fiscal year period while protecting from potential timing issues 10 involved with funding requirements and providing operational flexibility. 11 12 Stormwater Financial Plan 13 Q49. Does the proposed tax levy provide sufficient funding for the stormwater utility? 14 A. Based on the projected levels of stormwater O&M expense, CIRP, and reserve 15 requirements, the District’s stormwater operations will have sufficient funding over the 16 forecast period as shown in Table 6-5 of the Rate Change Proposal. 17 18 Rate Model 19 Q50. Have you developed a rate model as the basis of the analysis you have described in 20 this testimony? 21 A. We have worked with MSD Finance Staff to develop a comprehensive financial 22 planning, cost of service and rate model that underpins the analyses described in my 23 testimony as well as throughout the Rate Change Proposal. The District is the owner of 24 2015 Rate Change Proceeding 19 MSD Exhibit No. MSD 3H Direct Testimony of William Stannard, Raftelis February 26, 2015 that model and will be providing electronic versions of the model to the Rate 1 Commission as well as any intervener who requests it. 2 3 Q51. Does this conclude your direct testimony in this matter? 4 A. Yes 5 6 2015 Rate Change Proceeding 20 MSD Exhibit No. MSD 3H
