LOUIS SEWER DISTRICT JUNE 7, 2011 FIRST DISCOVERY REQUEST OF THE MISSOURI INDUSTRIAL ENERGY CONSUMERS Metropolitan St. Louis Sewer District Response ISSUE: WASTEWATER RATE CHANGE PROPOSAL WITNESS: METROPOLITAN ST. LOUIS SEWER DISTRICT SPONSORING PARTY: MISSOURI INDUSTRIAL ENERGY CONSUMERS DATE PREPARED: JUNE 17, 2011 Metropolitan St. Louis Sewer District 2350 Market Street St. Louis, Missouri 63103 BEFORE THE RATE COMMISSION OF THE METROPOLITAN ST. LOUIS SEWER DISTRICT For Consideration of a Wastewater Rate Change Proposal by the Rate Commission of the Metropolitan St. Louis Sewer District JUNE 7, 2011 FIRST DISCOVERY REQUEST OF THE MISSOURI INDUSTRIAL ENERGY CONSUMERS Metropolitan St. Louis District Response Pursuant to §§ 7.280 and 7.290 of the Charter Plan of the Metropolitan St. Louis Sewer District (the "Charter Plan"), Operational Rule 3(5) and Procedural Schedule §§ 17 (b)(i) and (ii) of the Rate Commission of the Metropolitan St. Louis Sewer District ("Rate Commission"), the Metropolitan St. Louis Sewer District ("District") thereby responds to the Missouri Industrial Energy Consumers June 7, 2011 First Discovery Request for additional information and answers regarding the Rate Change Notice dated May 10, 2011 (the "Rate Change Notice"). 2 JUNE 7, 2011 FIRST DISCOVERY REQUEST OF THE MISSOURI INDUSTRIAL ENERGY CONSUMERS Metropolitan St. Louis Sewer District Response Referring to Exhibit MSD 1, please provide an electronic copy, with all foliuulas intact, of the May 10, 2011 Metropolitan St. Louis Sewer District wastewater rate proposal performed by Black & Veatch. Please note whether or not any revised model has been made since May 10, 2011, and provide an electronic copy of the updated version. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: Exhibit MSD 4, Exhibit 4a and Exhibit MSD 5 provide all the tables, detailed calculations and formulas underlying the rate model used to develop the Rate Change Proposal (Exhibit MSD 1). No revisions have been made since its submittal to the Rate Commission. 1-2. Concerning the Black & Veatch wastewater rate proposal included in Exhibit MSD 1, please provide the following: a. All supporting analyses, and spreadsheets with formulas intact, supporting all key rate proposal assumptions outlined at page 1-3 of the report. RESPONDER: Jan Zimmeiiiian, MSD Director of Finance RESPONSE: Exhibit MSD 16A10 provides a cross reference of requested information for the key assumptions outlined at page 1-3 of the Rate Change Proposal (Exhibit MSD 1) b. A complete copy of all analyses supporting the projected decrease in wastewater volume from 69.3 million CCF in 2011 to 68.0 million CCF in 2016 due to a decline in non-residential and unmetered accounts stated at page 1-4 of the report. Please also explain how this decrease in non-residential volume was considered in estimating the decrease in revenue associated with the surcharges for BOD, COD and SS on that same page. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: A discussion of projected accounts and billed wastewater volume is presented on Pages 3-1 to 3-4 of the Wastewater Rate Proposal (Exhibit MSD 1). Table 3-2 of the report projects a 1.9 percent decline in billed volume for the five fiscal years of 2011 — 2015 with this decreased volume leveling out in 2016 versus a 12.5 percent decline for the preceding five years of 2006 — 2010. Detailed calculations supporting the projected billed wastewater volume are presented in Exhibit MSD 4a, Pages B-4 through B-9. Projections of surcharge loadings are not linked to billed wastewater volumes since a reduction in wastewater volume does not necessarily cause a reduction in wastewater strength loadings. 3 c. Please identify all routine capital expenditures noted at page 1-4 in item 8, and explain how MSD derived an increase in this level of expenditures. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Projected routine capital expenditures or capital outlays are treated as a separate line item without detail concerning individual equipment or vehicle purchases. A discussion of wastewater related routine capital improvements is presented on Page 3-11 of the Wastewater Rate Proposal (Exhibit MSD 1). Table 3-7 of the report shows the capital outlay projection on Line 22. Detailed calculations supporting the projected capital outlays for each Department are presented in Exhibit MSD 4a, Pages D-1 through D-19 where total wastewater related capital outlays are shown on Page D-19. d. Please provide all studies that show the available terms and current interest rates of rate revenue tax-exempt financing identified at page 1-5, paragraph 11, and the same for the term of the state revolving funds, and related interest rates. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Available terms and current interest rates of tax-exempt financing vary by utility and depend upon the utility's bond rating and current market conditions. Terms for current debt issuances can be found in a recent Bond Buyer publication or on the Bond Buyer's web site. Terms anticipated for future debt are summarized in paragraph 11 of Page 1-5 and Page 3-16 of Exhibit MSD 1. Detailed terms and calculations of debt service related to each existing traditional revenue bond are shown on Pages L-1 through L-4 and on Pages M-1 through M10 of Exhibit MSD 4a for SRF loans. A review of the 25 -Year Revenue Bond Index produced by Bond Buyer since 1991 shows an average interest rate over the 20 year period of 5.61 percent with current rates at about 5.3 percent (Exhibit MSD 16A). e. Concerning page 2-1, historical and projected operating expenses, please identify all major new operation and maintenance expense activities in the forecasted level, and escalation for existing operation and maintenance tasks used to develop the forecasted level of expenses. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: New operating expense activities include allowances for future rate change proceedings, decreased costs in contractual services for the Finance Department as costs to collect past due amounts by outside contractors decrease, increased contractual services for the Information Services Department to continue enhancements to the District's information systems and increased operating costs related to new facilities constructed during the study period. Operating expenses for FY14 and FY15 also reflect increases associated with regulations requiring disinfection at District treatment plants. Detail supporting these changes are presented at projected cost levels on Pages D-8 through D-13 of Exhibit MSD 4a for existing -4- facilities and on Page D -13a of Exhibit MSD 4a at a 2008 cost level for operating anticipated new facilities. Cost escalation factors are identified on Page 2-3 of Exhibit MSD 1 and Page D-1 of Exhibit MSD 1. Please provide all management reports where changes in current operation and maintenance activities, and costs associated with the same have been presented to executive board members of the MSD, and any engineering reports outlining the MSD Staffs recommended level of projected operation and maintenance activities. RESPONDER: Jon Sprague, MSD Director of Operations RESPONSE: The EPA Consent Decree (Decree) refers to the Capacity Management Operations and Maintenance (CMOM) activities required as part of this settlement. An ordinance, including support detail, providing District authority to sign the Decree was introduced at the June 9, 2011 meeting of the MSD Board of Trustees (Board) for its full consideration. The ordinance detail is provided as Exhibit MSD 11A32. While the District is not anticipating any major increases in its workforce to support CMOM activities, Staff responsibilities have been modified as represented in Exhibit MSD 16B. Additionally, Exhibit MSDB 1 outlines changes to current operations and maintenance activities recommended for FY12. g. Referring to page 2-4, Table 2-2, please provide the allocation between wastewater and storm water of direct operating costs as used in MSD's last rate filing, and explain any changes in the allocation between wastewater and stotiu water of common operating costs in this case relative to the last case. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The allocation of utility costs was previously provided as Table 2-2 on Page 2-4 of Exhibit MSD 1 from the 2007 rate case. The prior rate case was predicated on a new impervious area based user charge that would increase stormwater services with transitional support from the wastewater utility through fiscal year 2008. The current rate case assumes a level of stormwater service supportable by available stormwater revenues and thus decreases the relative level of stormwater costs. The allocations used in the current rate case were also compared with the District's segmented wastewater/stormwater utility financial records for verification purposes. h. Referring to page 2-7, Table 2-4, please provide a comparison of the allocation of other operating revenue between wastewater and storm water in MSD's last rate case, compared to the allocation proposed in this case in Table 2-4. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The allocation of miscellaneous income was previously provided as Table 2-10 on Page 2-17 of Exhibit MSD 1 from the 2007 rate case. The prior rate case was based on a new impervious area user charge that would increase stormwater services with transitional support from the wastewater utility through fiscal year 2008. The current rate case assumes a level of stormwater service supportable by available stormwater revenues from taxes and a small flat rate charge and thus decreases the relative level of stormwater costs that could be offset by operating revenues. The allocations used in the current rate case are thus more heavily weighted toward wastewater. i. Please provide a study of all changes in customer growth used and discussed at Section 3-1, under customer growth, and the related wastewater volume at that same page in paragraph 3.2. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Detailed calculations supporting expected changes in customer growth and projected billed wastewater volume are presented in Exhibit MSD 4a, Pages B-4 through B-9. With respect to the change in customer growth and volume growth, please provide copies of any state or local economic reports projecting changes in non-residential customer growth which can be used to gauge the relative outlook used in the Black & Veatch report for MSD relative to that used by state or local governments projecting future economic activity. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Customer growth was based on historic trends and projected billed volume was based on projected growth and expected billed volume per customer. State and local economic reports that may project changes in customer growth were not identified or considered in the proj ections. k. On an electronic spreadsheet with all formulas intact, please provide the analyses used to develop the wastewater service charge revenue for metered and unmetered services in paragraph 3-4 for wastewater revenue under existing rates. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Projected number of customers, projected billed volume and projected surcharge loadings were applied to fiscal year 2011 wastewater rates to project wastewater revenue under existing rates as discussed in Section 3.4 of the Wastewater Rate Proposal (Exhibit MSD 1). Detailed calculations supporting this calculation are shown on Pages B-1 through B-15 of Exhibit MSD 1 with the total revenue under existing rates, which matches Table 3-5 of the report, shown on Page B-15 of Exhibit MSD 4a. A formula showing the basic calculation of each page is typically included at the top of each calculation sheet along with page references of where values used in the calculation can be obtained. In addition formulas for each cell shown in Exhibit MSD 4a are available in Exhibit MSD 5. 1. Please provide a projection of wastewater revenues under proposed rates on an electronic spreadsheet with all formulas intact using the same billing determinants as used to develop the revenue charges under current rates in paragraph 3-4, page 3-6 of the report. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: A multi -year projection of wastewater revenue under proposed rates, similar to the projection under existing rates, is not available in the Wastewater Rate Proposal. However, revenue increases shown on Lines 2 through 6 of Table 3-11 on Page 3-18 of Exhibit MSD 1, together with revenue under existing rates (Line 1 of Table 3-11) should be representative of wastewater revenue under proposed rates. Total projected wastewater revenue is shown on Line 8 of Table 3-11. m. On an electronic spreadsheet with all formulas intact, please provide the spreadsheet used to produce the projected wastewater operating revenue. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: Exhibit MSD 4, Exhibit 4a and Exhibit MSD 5 provide all the tables, detailed calculations and formulas underlying the rate model used to develop the Rate Change Proposal (Exhibit MSD 1). n. For each category of projected wastewater operating cost shown in Table 3-7, please provide a description showing the rationale and expected inflation and other changes for annual operating costs for each of the identified operating cost categories. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Support for Table 3-7 is provided by Pages D-1 through D- 19 of the detailed calculations (Exhibit MSD 4a). Budget values for fiscal year 2011 are inflated at the rates shown in Page D-1 with any known changes in operating costs recognized. Costs for power and chemicals at pump stations and treatment plants are further adjusted for changes in billed wastewater volume. Similar support for additional O&M due to the completion of new facilities is available on Pages D -13a and D-30 of Exhibit MSD 4a. o. Please provide a complete copy of the 20- to 30 -year capital improvement program budget for MSD, and compare the capital improvements through 2016 shown on page 3-13 of the Black & Veatch report with that 20 -year CIP forecast. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: The CIRP numbers shown in the Rate Change Proposal (Exhibit MSD 1) for 2011 — 2016 are based on the same time period as in the 20 to 30 year capital program underlying the Consent Decree. An ordinance to authorization the District to sign the Decree was introduced for consideration by the Board at its June 9, 2011 meeting. However, the District is not a liberty to provide a complete version of the long term CIRP program until the Decree is lodged with the Court. P. q. Please explain how the capital improvement program shown at page 3-13 of the Black & Veatch report, compares with the current settlement for the Consent Decree which MSD recently entered into with the EPA. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: Same as response to Question 0 above. Referring to page 3-13 of the Black & Veatch report, wastewater capital cost financing, please identify any grants, low interest rate loans, or any other source of funding the Consent Decree capital programs available but where the MSD did not quality for them. Please explain the rationale for the source of funding actually considered by Black & Veatch in its rate projections. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The source of funding for low-cost SRF loans is limited to state-wide funds available for all qualified projects and the amount of qualified projects requesting such funding. The Wastewater Rate Report assumes the District will be able to obtain $35 per year of SRF loans. A $1 million grant is anticipated to be received in fiscal year 2013 for rehabilitation of a River Des Peres foul water interceptor. Additional information concerning SRF loans is provided in the District's response to Q1-31 and Q1 - 34. The District's response to Q1-33 addresses grant funding. r. Concerning pages 3-21 through 3-31, please provide a five-year history of all volume costs, capacity costs and wastewater strength costs used to develop the class cost of service study in the Black & Veatch report. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Historic data in this format is not determined or maintained by the District nor available in the rate model. s. Concerning page 3-21 of the Black & Veatch report, it identifies capital capacity cost as being related to facilities that are designed to meet the maximum or peak rates of wastewater flow. Please provide all workpapers used to develop the capacity cost units of service as shown at page 3-31 of the Black & Veatch report in Table 3-17. Please also clearly define what these units of service represent, and show what they have been over the last five years. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Capacity units of service shown in Table 3-17 of Exhibit MSD 1 were developed in Table 3-16 of the same exhibit. Support for these values is calculated on Page J-7 of Exhibit MSD 4a. Capacity related units of service represent relative peak flows during dry weather and wet weather conditions and are primarily used to allocate collection system and pumping related costs to customer classes. Historic data of this nature is not determined or maintained by the District. t. Please provide the same five-year history of number of units for volume, capacity, wastewater strength, and all customers and non-residential customers shown in Table 3-17 on page 3-31 of the Black & Veatch report. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Information in the detailed calculations (Exhibit MSD 4a) can be used to determine historic units of service for all parameters except capacity because historic capacity factors are not available. Total wastewater volume for all treatment facilities is summarized on Page J-4 in million gallons per day and converted to hundred cubic feet (Ccf) in the table below. Billed wastewater volumes can be compared with these values to determine average annual I/I for the five-year period of 54 percent. For the Wastewater Rate Proposal, an average I/I percent of 55 percent was used and applied to the test year billable volume to derive the total volume units shown in Table 3-17. Total wastewater strength loadings of the wastewater treatment plants are also summarized on Page J-4 of the detailed calculations and converted to pounds per year in the table below. Average wastewater strengths for the five year period was 96 parts per million (ppm) for BOD and 171 ppm for suspended solids. These values were rounded to 100 ppm and 170 ppm and applied to total wastewater volume to estimate test year wastewater strength loadings for the rate report. Total bills are summarized on Page B-4 of the detailed calculations. Historic non-residential equivalent bills can be approximated by multiplying non-residential accounts shown on Table 3-1 by a constant (K) determined in Table 3-22 of the rate report by dividing the 2010 number of equivalent bills (1,037,700) by the 2010 number of non- residential accounts (25,165).

Concerning the Consent Decree capital projects, and operation and maintenance expense projects included in the five-year rate plan developed in the Black & Veatch report, please explain the following: a. Explain how the Consent Decree alters or has influenced the capital program related to the collector system of the MSD throughout the rate forecast period. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: The CIRP as proposed matches that reflected in the Consent Decree. An ordinance authorizing the District to sign the Consent Decree was introduced to the Board on June 9, 2011. b. Please explain how changes in the collector systems, and volume of water will be changed as a result of the capital improvements necessary to comply with the Consent Decree? RESPONDER: Jon Sprague, MSD Director of Operations RESPONSE: While the specifics of the Consent Decree are still confidential, the accompanying fact sheet, provided as Exhibit MSD 11A32, spells out the CIRP requirement to reduce CSO's and eliminate SSO's. The reduction in CSO's and SSO's will require the increase of flows to treatment plants serving the combined sewer system and an estimated overall slight decrease in flow to treatment plants serving the separate sewer system. This will be accomplished through a combination of continued proactive maintenance of the existing system, increasing capacity through completion of CIRP projects and the controlled feeding of excess wet weather flows to treatment plants through temporary capture and storage. The Consent Decree is a long tent' program and these changes will happen over time. As the program progresses flows may increase or decrease in the interim as projects and the program progress. c. Please identify the capital projects needed to comply with the Consent Decree and separate them by impacts on collector systems, and pumping stations, and water treatment capacity. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: A categorized five year CIRP project list, including Consent Decree capital projects, is provided as Exhibit MSD 16C. The list is categorized by project type: CSO-Combined Sewer overflow, SSO-Separate Sewer Overflow, Cityshed, Treatment Plant, Asset management Renewal, and Asset Management Capacity. The project listing has not been segregated to the exact impacts listed above, but is similarly segregated. - 10 - d. Please identify any aspect of the Consent Decree which changes the MSD's cost for treating BOD, SS or COS in water treatment plant. RESPONDER: Jon Sprague, MSD Director of Operations RESPONSE: The Consent Decree projects are not expected to increase MSD's unit costs (e.g., dollars per pound treated) for treating BOD, SS, or COD at the wastewater treatment plants. The Consent Decree projects will ultimately result in larger quantities of these constituents being treated during wet -weather conditions, thereby increasing total treatment costs. e. Please identify any implications on the collector system for BOD, SS or COS in complying with the Consent Decree as it approaches the water treatment plant. RESPONDER: Jon Sprague, MSD Director of Operations RESPONSE: The Consent Decree projects are not expected to have a significant impact on BOD, SS, or COD concentrations in the collection system as it approaches the wastewater treatment plant. Concentrations of these constituents are not expected to change at all during dry -weather conditions as a result of the Consent Decree projects. Concentrations during wet -weather conditions may be nominally increased due to efforts to reduce wet weather flows by infiltration/inflow control in the sanitary sewer system and green infrastructure projects in the combined sewer system. For both 1-3d and 1-3e, please note the minimal impacts to plants or systems will be very gradual and years down the road. Due to the timeframe to implement projects, we would suspect limited if any change during the upcoming rate cycle. 1-4. Please provide a map of the entire MSD system showing locations of non- residential customers and the collector size mains used to serve these customers. Please provide the same information for residential customers. RESPONDER: Jonathon Sprague, MSD Director of Operations RESPONSE: The District maintains a GIS system which provides spatial data of the entire MSD system infrastructure. This data, however, does not provide a break down between residential and commercial customers. 1-5. Please provide a cost estimate of MSD's collector mains by size of pipe, or pressure of pipe. RESPONDER: Jonathon Sprague, MSD Director of Operations RESPONSE: An estimate of the replacement and rehabilitation costs of MSD's collector mains was prepared as part of the District bond due diligence in 2010. This is only an estimate based on general replacement and rehabilitation costs by pipe size and does not reflect actual conditions of the pipe or field conditions. The collection system is a gravity system and pressure has no impact on costs. This analysis is provided as Exhibit MSD 16D. 1-6. On an electronic spreadsheet with all formulas intact, including a copy of all tariff rate information, please provide copies of analyses performed by MSD, or Black & Veatch, comparing MSD's current and projected wastewater rates to wastewater rates of other wastewater utility systems around the country. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: A comparison of District wastewater rates with rates of other wastewater utilities was not conducted by the District or by Black & Veatch as part of the recent rate studies. However, information is provided in Section 5.5 of Exhibit MSD 1 concerning comparisons of typical residential bills of the District with those previously surveyed by Black & Veatch and a survey by the National Association of Clean Water Agencies (NACWA). In addition, Exhibit MSD 16A11 compares MSD to the 50 largest city survey by customer class and indicates as volume increases, the ranking of St Louis relative to the 50 largest cities significantly improves. This survey indicates MSD rates are more favorable to large customers than other cities. 1-7. Please provide all workpapers, analyses and studies used to support the assumption that billed wastewater volume will continue to decrease but will level off towards the end of the study period. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The assumption that billed wastewater volume will continue to decrease but will level off towards the end of the study period is based on historical trends, the realization there must be a limit to conservation efforts and an expectation the economy will eventually get improve. 1-8. Please provide copies of MSD's annual reports for the three most recently completed fiscal years. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: MSD's 2008, 2009 and 2010 annual financial reports known as the Comprehensive Annual Financial Report (CAFR) are provided as Exhibit MSD 16E, Exhibit MSD 11A2 and Exhibit MSD 11A3, respectively. The - 12 - District's Annual Reports for 2008, 2009 and 2010 may be found using the following link at MSD's website: http://w %.stl sd.com/aboutmsd/fiscal/annualreport 1-9. Please provide complete copies of all credit ratings reports of MSD issued by Moody's, Standard & Poor's, Fitch or any other firm that rates corporate and municipal debt credit rating, issued over the last two years. RESPONDER: Karl Tyminski, MSD Secretary / Treasurer RESPONSE: Complete copies of MSD's Moody's, Standard & Poor's and Fitch credit rating reports are provided as Exhibit MSD 16L, Exhibit MSD 16M and Exhibit 16N. The following questions relate to the direct testimony of Jeffrey L. Theerman, MSD Exhibit No. 9: 1-10. In reference to page 8, Q29, please identify all new regulations being considered by regulators and the potential dollar impact those new regulations may have on wastewater utilities. RESPONDER: Jeff Theerman, MSD Executive Director RESPONSE: New environmental regulations are in a constant state of development at both the Federal and State level. MSD includes involvement in that regulation development as part of its Strategic and Operating Plan. The most likely areas where regulatory decisions will affect the District include: Mississippi River Water Quality Standards — Since 2004 MSD has been in discussions with both State and Federal regulators about potential changes to the water quality standards for the 28 mile segment of the river at St. Louis. The District believes the river velocities, barge traffic, bank slope, river access, and a lack of any swimming in the segment make a swimming standard inappropriate. MSD has conducted two separate Use Attainability Analysis (UAA) have conclusively shown swimming is not a current use nor is it attainable for the above listed reasons. In spite of MSD's scientific data, the USEPA has insisted that the state promulgate a swimming standard. The State is currently contemplating requiring such a standard and has begun the process by reporting as such to the Missouri Clean Water Commission. While we continue to try to bring an appropriate conclusion to this issue, it remains to be seen what standard will be imposed. The potential financial impact of this decision was estimated in the development of the MSD CSO Long Term Control Plan as $1.5 Billion. This additional cost is over an above the estimated $4.7 Billion cost of the proposed Consent Decree. The District's Long Term Control Plan is available at the following link on the MSD website: https://www/stlmsd.com/educationoutreach/bestpractices/combinedseweroverflow Sewage Sludge Incineration Rules — EPA has promulgated new rules governing Sewage Sludge Incinerators. MSD currently incinerates approximately 60,000 - 13 - tons of sewage sludge each year at two treatment plants. This process has continued to be the most cost effective treatment and disposal alternative for this treatment plant byproduct. MSD has invested significantly in air pollution controls on these incinerators but may now have to accelerate plans to replace these incinerators with new technology. Current plans are to make a technology changes at the end of the useful life of the current incinerators ten or more years from now. It is unclear if this rule change will force the District to advance its investment in this area. MSD is a member of a group of over 40 utilities that is challenging this rule change on a number of grounds. The estimated cost of this rule, if it forces a process change at MSD, is estimated at $250 Million. This additional cost is over an above the estimated $4.7 Billion cost of the proposed Consent Decree. Nutrients — Nationally the issue of nutrient pollution is becoming significant. Nutrients, typically nitrogen and/or phosphorus, act as fertilizer in water bodies causing algae blooms and depleted oxygen levels. Nutrient pollution is responsible for the hypoxic zone in the Gulf of Mexico. The EPA and the States have been including nutrient removal requirements on treatment plants in the Chesapeake Bay, Florida, and several other regions. Nutrient removal is not a requirement at any of the MSD existing treatment plants on the Missouri or Mississippi Rivers. It is very likely that these facilities will have nutrient removal requirements within ten years. The cost of these process changes has not been estimated because the standards to be achieved are presently not determined. The additional cost would be over an above the estimated $4.7 Billion cost of the proposed Consent Decree. As stated in my testimony in Exhibit MSD 9, it is not possible to anticipate all new regulations. Other areas which may see increase regulatory burden include, immerging contaminants, climate change, mercury, increased treatment to comply with Total Maximum Daily Loan determinations, and security requirements. Although not part of this rate case, stormwater utilities are likely to see significantly increased regulation as well. 1-11. Please identify, state the amount, and describe any fines or penalties included in MSD's Rate Change proposal. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: No fines or penalties are included in the Rate Change proposal. This includes the $1.2 million civil penalty that is part of the recent Consent Decree settlement. However, the anticipated payment of this penalty is factored into fiscal year 2012 and will not affect the proposed rates. The impact of this civil penalty will be a reduction in the balances shown in Table 3-9 of the Wastewater Rate Proposal and a slight decrease in fiscal year 2012 debt service coverage since the civil penalty is considered to be an operation and maintenance expense. - 14 - The following questions relate to the direct testimony of Brian L. Hoelscher, MSD Exhibit No. 9B: 1-12. In reference to page 2, Q10, please identify all wastewater capital improvement adjustments that have been made over the last five years to address changing regulatory requirements and identify the total dollar impact on ratepayers associated with those adjustments. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: The largest regulatory change was the requirement to install disinfection at 4 of MSD's Treatment Facilities. At three of the facilities (Lemay WWTP- $25 million, Bissell WWTP- $28 million, Lower Meramec- $5 million) no disinfection requirements were anticipated. While disinfection requirements were anticipated at the Missouri River Treatment Plant, inability to re -use existing facilities as part of the overall expansion as originally planned increased costs by $30 million. Other regulatory requirements became apparent during the past five years as well, primarily originating from MSD's continuous discussions with EPA and MDNR. These include a $3 million Green Pilot Program to abate the impact of CSO's, a $10 million project in North St. Louis City to purchase a subdivision and install a detention basin where existing residents were severely impacted by surcharging combined sewers, and $16 million in Sewer Cleaning to proactively address overflows in the sewer system. All of these activities are referred to in the fact sheet for the proposed Consent Decree. The total dollar impact on the ratepayers during the last 5 years would be the total of these projects, or approximately $117 million. Planned projects were delayed to provide funding for these additional projects within the District's funding limits over the past 5 years, however, the delayed planned projects will eventually have to be addressed. 1-13. With regard to MSD's June 2 agreement with the U.S. Environmental Protection Agency, please provide an updated wastewater capital improvement and replacement program cost projection for the period FY 2011 through FY 2016 associated with the construction of only those projects necessary to comply with the terms of the June 2 agreement. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: No such update is available or necessary. The CIRP in the Rate Change Proposal (Exhibit MSD 1) reflects that in the Consent Decree introduced for signature authorization at the June 9, 2011 meeting of the MSD Board. - 15 - 1-14. Please identify all adjustments to MSD's engineering consultant delivery model to assure cost-effective and timely completion of MSD's capital improvement and replacement program. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: MSD will now be contracting with consultant teams to address geographic areas that have similar regulatory issues instead of going through a consultant selection process for every individual project. Time and cost will be saved by reducing the amount of effort required for the selection process, by having immediately available resources to evaluate time and cost saving opportunities, by having resources immediately available to pursue design opportunities that can save money and cost, by having resources immediately available to address unanticipated problems, and allow for better overall coordination of activity within each geographic area. MSD has completed the reorganization of its Engineering Department to be able to manage this process. The change in the consultant delivery model and the reorganization of the Engineering Department will allow it to execute the proposed capital program without an increase in Staff. 1-15. Please identify by rate year what portion of MSD's wastewater capital improvement and replacement program is required to comply with state requirements. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: All the CIRP projects reflected in the Rate Change Proposal (Exhibit MSD 1) are required to comply with State requirements per the Consent Decree introduced for signature authorization at the June 9, 2011 meeting of the MSD Board. Note that State and Federal regulatory requirements are essentially equal. 1-16. Please identify by rate year what portion of MSD's wastewater capital improvement and replacement program is required to comply with federal requirements. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: All the CIRP projects reflected in the Rate Change Proposal (Exhibit MSD 1) are required to comply with Federal requirements per the Consent Decree introduced for signature authorization at the June 9, 2011 meeting of the MSD Board. Note that State and Federal regulatory requirements are essentially equal. 1-17. In reference to page 3, Q16, Mr. Hoelscher states that all of the wastewater capital improvement and replacement program projects are designed to meet regulatory requirements and schedules anticipated based on the current status of the EPA mediation and therefore cannot be delayed. With regard to MSD's June 2 agreement with the EPA, please identify all wastewater capital improvement and - 16 - replacement program projects included in MSD's six -year study that could be delayed and identify the per year dollar reduction associated with those projects. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: None of the projects in the CIRP contained in the Rate Change Proposal (Exhibit MSD 1) may be changed. The CIRP correlates with that in the Consent Decree and as such is needed in its entirety to meet regulatory requirements. Note that there may be a few projects in the CIRP, such as the Prospect Hill Landfill project that is needed to meet regulations regarding the proper disposal of incinerator ash, that may not be specifically required by the Consent Decree but are required to meet environmental regulations in the most cost effective manner possible. 1-18. Please provide a copy of MSD's August 2009 Long Term Control Plan. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: The size of the Long Term Control Plan document makes a copy impractical to provide. The District's August 2009 Long Term Control Plan may be found using the following link on the MSD website: https://wmT.stlmsd.com/educationoutreach'bestpractices/combinedseweroverflow 1-19. Referring to page 5 of Mr. Hoelscher's testimony, he states that due to economic conditions, the District will be receiving bids for capital work that in some cases were 40% below traditional cost. With respect to this testimony, please identify how this below traditional cost construction bidding has impacted the projected level of capital expenditure costs included in the MSD's current rate filing, and provide a complete copy of all assessments the MSD Staff has taken to deteiiuine whether or not the current low capital improvement bidding costs can be used to minimize the construction projects budgeted to be completed over the next four years, 10 years and 20 years. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: Current economic conditions were not assumed to be in place during the current proposed rate study period, or during the 10 or 20 year horizon. If economic conditions during the current rate period continue to be favorable, MSD would continue its current practice of accelerating the program to take advantage of the associated cost savings and reduce the overall cost of the program. Any economic conditions beyond the current proposed rate study period would be taken in the account in the next rate change proceeding. 1-20. Referring to pages 5 and 6 of Mr. Hoelscher's testimony, please answer the following: a. Please identify the sanitary sewer overflows (SSO) and how these overflows are spread across MSD's collector systems. Specifically, please identify - 17 - whether or not the SSOs are directly related to certain sizes of sewer lines, pump stations or other measures on the system. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: A map of the constructed SSO and CSO locations is provided as (Exhibit MSD 16F). SSO's are not related to the size of sewer lines or pump stations and in all locations are most directly related to inflow and infiltration of stormwater and groundwater into the separate sanitary sewer system. b. Please answer the same question above but with respect to the combined sewer overflows listed above. RESPONDER: Brian Hoelscher, MSD Director of Engineering RESPONSE: A map of the constructed SSO and CSO locations is provided as Exhibit MSD 16F. The regulatory requirement regarding CSO abatement is not related to the size of sewer lines or pump stations. CSO's are directly related to the original design of the system in that they are constructed to activate and discharge upon a storm event that exceeds the capacity of the interceptor. The following questions relate to the direct testimony of Janice M. Zimmerman, MSD Exhibit No. 9D: 1-21. In reference to page 2, Q7, please provide a copy of all material relied on to support the statement that "The proposed wastewater rate increase is fair and reasonable in that it proportionately distributes the District's projected costs over all classes of ratepayers." RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: The basis for the cited quotation is the 1997 decision by the Missouri Court of Appeals following a retransfer of the case from the Missouri Supreme Court, which found MSD's sewer service charges to be a fee and not a tax. A general chronology of this past wastewater litigation is provided as an excerpt from the March 7, 2007 Direct Testimony given by Randy Hayman, the then MSD General Counsel, during the 2007 Rate Commission rate change proceeding. This excerpt is provided as Exhibit MSD 16G In addition, the October 25, 2002, August 13, 2007 and April 1, 2008 Rate Recommendation Reports submitted by each respective Rate Commission found the methodology used to design the District's wastewater rates did not "impose an unfair or excessive burden on one or more classes of ratepayers" per MSD Charter Section 7.300(b)(5). These recommendations may be found as following: 1) Exhibit MSD 16G1: 2002 Rate Commission Recommendation Report (prior to deliberations) - 18 - The last paragraph on page 60 of this Exhibit states "The Rate Commission, after consideration of all the facts and circumstances disclosed in the Proceeding, finds and determines that the Rate Commission Wastewater Rate Change Recommendation imposes a fair and reasonable burden on all classes of ratepayers." 2) Exhibit MSD 6 : 2007 Rate Commission Recommendation Report (prior to deliberations) The second paragraph on page 159 of this Exhibit states "The Rate Commission, after consideration of all the facts and circumstances disclosed in the Proceeding, finds and determines that the elimination of the resistance factor from the rates in the Rate Change Proposal results in rate for Wastewater Services that impose a fair and reasonable burden on all classes of ratepayers." 3) Exhibit MSD 7: 2008 Rate Commission Recommendation Report (prior to deliberations) The last paragraph on page 179 of this Exhibit states "The Rate Commission, after consideration of all the facts and circumstances disclosed in the Proceeding, finds and determines that the 2008 Proposed Rate Change imposes a fair and reasonable burden on all classes of ratepayers." All three recommendation reports included Minority Reports from various groups of Rate Commissioners. None of these Minority Reports contradicted the finding that the wastewater rate was fair and reasonable. The District's wastewater rate design has not changed since the Rate Commission's initial 2002 Rate Recommendation Report. 1-22. Please provide a detailed description as to how MSD's proposed five -tiered cost structure for recovering MSD's environmental compliance monitoring costs from non-residential customers was developed. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: A description of how MSD's proposed five -tiered cost structure for recovering MSD's environmental compliance monitoring costs from non-residential customers was developed and is provided in Section 3.9.2.3 of the Rate Change Proposal (Exhibit MSD 1). The underlying concept of the proposed five -tier rate structure is to better align relative costs of monitoring different groups of non-residential customers with the charges imposed on non-residential customers for such relative monitoring efforts. 1-23. Please identify MSD's projected environmental compliance costs for - 19 - non-residential customers for each year of MSD's six -year rate proposal and identify the portion of costs recovered from each customer tier level. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Total projected environmental compliance revenue for each year of the six -year study period by each tier is compared to allocated costs for the compliance program during the transition period in the table below. Revenue is projected by applying the 2010 percentage distribution of customers identified in Table 3-22 of Exhibit MSD 1 to the total number of non-residential accounts shown in Table 3-1, multiplying by 12 to get annual bill distributions and then multiplying these distributions by the respective monthly environmental compliance charges shown in Table 3-21. Revenues shown for Tier 2 through Tier 5 also represent costs of service for the four respective tiers in fiscal years 2013 through 2016. Costs to be recovered by the environmental compliance charge significantly decrease in fiscal year 2013 due to the reallocation of costs to all customers to reflect system wide benefits of the program. The Tier 1 charge is decreased over a four-year transition period to lessen the immediate rate impact on residential customers that are absorbing a large share of the costs foirnerly only recovered from non-residential customers. 2011 2012 2013 2014 2015 2016 $ $ $ $ $ $ Revenue Tier 1 8,741,900 8,981,500 6,439,600 4,479,700 2,509,700 655,300 Tier 2 162600 167,100 209,600 221,900 228,500 235,200 Tier 3 250,900 257,800 688,600 728,400 750,700 772,700 Tier 4 84,600 86,900 340,300 360,000 370,900 381,800 Tier 5 55,800 57,300 295,700 312800 322200 ` 331,800 Total 9,295,800 9,550,600 7,973,800 6,102,800 4,182,000 ' 2,376,800 Cost 9,295,800 9,550,600 2,113,900 2,229,600 2,304,600 2,372,500 1-24. Please provide a copy of the 2008, 2009, 2010, 2011 and 2012 preliminary operating budget and five-year Wastewater Improvement and Replacement Program supplemental budget presented to the District's Board in March. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: The requested budgets are provided as follows: 2008 Operating Budget 2008 CIRP Supplemental Budget 2009 Operating Budget 2009 CIRP Supplemental Budget 2010 Operating Budget 2010 CIRP Supplemental Budget 2011 Operating Budget 2011 CIRP Supplemental Budget 2012 Operating Budget 2012 CIRP Supplemental Budget Exhibit MSD 16H Exhibit MSD 16I Exhibit MSD 11A4 Exhibit MSD 11A6 Exhibit MSD 11A5 Exhibit MSD 11A7 Exhibit MSD 16J Exhibit MSD 16K Exhibit MSD 8 Exhibit MSD 8A - 20 - 1-25. Please provide a copy of all meeting minutes from the April 2011 Board of Trustees Finance Committee meetings to review in detail operating expenses, the CIRP and revenues projected for the budgeted 2012 year. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: A copy of the minutes from the April 2011 Board Finance Committee meeting is provided as Exhibit MSD 160. 1-26. Please identify and describe all inflation allowances used in the rate study report. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: All inflation allowances for operating costs are presented on Page 2-3 of the Wastewater Rate Proposal (Exhibit MSD 1) and on Page D-1 of the detailed calculations (Exhibit MSD 4a). A uniform inflation allowance of 3% per year is provided for CIRP projects. 1-27. Please provide a copy of all workpapers, analyses and studies used to develop MSD's identified inflation allowances used in the rate study report. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: See response to Question 1-26. Inflation allowances used in the rate study calculations are based on judgment with recognition of prior inflationary trends. 1-28. Please provide a complete copy of all of MSD's financial filings issued over the last five years. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: The requested financial filings are provided as follows: 2006 CAFR 2007 CAFR 2008 CAFR 2009 CAFR 2010 CAFR 2006 Annual Audit 2007 Annual Audit 2008 Annual Audit 2009 Annual Audit 2010 Annual Audit Supplemental Bond Ordinances Exhibit MSD 16P Exhibit MSD 16Q Exhibit MSD 16E Exhibit MSD 11A2 Exhibit MSD 11A3 Exhibit MSD 16R Exhibit MSD 16S Exhibit MSD 16T Exhibit MSD 11A2 Exhibit MSD 11 A28 Exhibits MSD 11L through 11V 1-29. Please provide a complete copy of all financial presentations MSD has made to credit rating agencies, or other sources of the state loan revolving agreement fund -21 - organization, or other sources of capital investigated by MSD to fund its capital improvement program. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: The requested information is provided as Exhibits MSD 16U through 16A1. The following questions relate to the direct testimony of Karl J. Tyminski, MSD Exhibit No. 9E: 1-30. In reference to page 2, Q6, please provide a copy of all credit rating agency median metrics material relied on to support the statement that "While projected debt coverage exceeds Master Bond Ordinance requirements the projected coverages are only in line with median metrics used by the credit rating agencies." RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: The requested information has been provided by Exhibits MSD 11C through 11J. 1-31. Please identify the max amount of State Revolving Fund (SRF) loans by rate year that MSD could receive over the course of MSD's proposed rate plan. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: The State will not commit in advance on available funding. Therefore, a projection using a "mosaic" approach was developed. This projection is initially based the State's FY2012 Intended Use Plan provided as Exhibit MSD 11W, which shows the resources of the State Revolving Loan fund (SRF) in conjunction with a graph of the size of the federal funding for State SRF funds provided as Exhibit MSD 16A2. This graph is also available from the EPA using the following link: http://www.americanwaterintel.com/archive/2/3/. An article from The Source Utility Enterprise Management magazine speaks to a 27% reduction in Federal funding to State revolving funds. This article is provided as Exhibit MSD 16A3. This information taken collectively provides the basis for the District's SRF funding projection. This projection, however, indicates the $35 million a year SRF funding assumed in the Rate Change Proposal (Exhibit MSD 1) may be overly optimistic. The District believes the State SRF program in future years will have receive $70 and $80 million in annual cash inflows from either repayments or new Federal monies to be made available statewide. MSD's historical share of the statewide pool has ranged from 20% to 40%. Currently MSD's share is closer to 40% because of its needs and strong credit rating. Assuming the SRF receives the higher funding level of $80 million and MSD share remains at 40%, the maximum anticipated SRF funding would be $32 million a year compared to the $35 million annual SRF funding assumed in the Rate Change Proposal (Exhibit MSD 1). This $12 million shortfall will need to be recovered through the issuance of a greater amount of revenue bonds, thereby placing additional pressure on maintaining the District's current AA bond rating. - 22 - 1-32. Please provide all internal and external communication that MSD has had regarding increased Missouri SRF program loans to help fund future MSD capital expenditure programs. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: MSD communications considered key to this response are provided as Exhibits MSD 16A4 through 16A8. Additional communications are unrealistically voluminous to provide. 1-33. Please provide all internal and external communication that MSD has had regarding contributions and grant monies from city, state or federal agencies. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: Exhibits MSD 16A represent the key MSD communications requested. Additional material is unrealistically voluminous to provide. 1-34. Please provide MSD's current level of Missouri SRF loan capability. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: The determination of MSD's current level of SRF capability requires the consideration of a number of uncontrollable variables which may be represented by the following four key questions: 1) Will the Missouri SRF be run as a cash basis or leveraged program? Historically until 2008, the State of Missouri has run a leveraged loan program which provided a large pool of available funds and was fairly flexible in terms of increased borrowing by a large borrower. This program worked due to the interest rate spread between the borrowing rate and the reinvestment rate resulting in a 70% subsidized rate to borrowers. The cost of borrowing at that time was in the 4% range while the reinvestment rate range was 5%, yielding an attractive positive spread. The 2008 economic downturn, however, in conjunction with the implementation of the Federal government's quantitative easing policy, has managed to keep a borrowing rate in the 4% range. The reinvestment rate, however, has dropped to 50 basis points resulting in an additional borrowing cost of 3.5% annually when compared to the historical SRF subsidized rates. Due to current budget constraints, the decision was made by the State to convert the leveraged SRF program, at least temporarily, to a cash basis. A cash basis program is constrained by the cash receipts in a given year plus any monies not taken by other entities. Currently, the repayment of existing loans is approximately $50 million annually. This is partially offset by "Federal CAP Grants" of approximately $30 million. The State, therefore, is expected to have $80 million available on an annual basis. Due to the 70% subsidized structure of this program, the $80 million statewide funding level can support approximately $115 million per year. The level of supported annually funding increases as the subsidy level - 23 - declines. For example, a 50% subsidy would support approximately $160 million in loans annually on a statewide basis. 2) What is the statewide demand for the program? The demand prior to the stimulus funding of 2009 (ARRA funding) was less than robust. However, the stimulus program coupled with DNR's pressure on smaller communities for Clean Water Compliance has increased the demand for Clean water SRF funds on a statewide basis. 3) At what point does a concentration of debt by MSD become a credit risk to the pool? MSD's current high credit rating serves as a benefit to the SRF program as it provides a partial offset for lower rated municipalities also participating in the funding pool. MSD's current rating coupled with its concentration of debt becomes a risk to the overall SRF pool at approximately $400 million. This amount will decline if MSD's credit rating deteriorates. 4) What is an equitable distribution of the total SRF available funds from a statewide allocation perspective? An allocation based on population is the most reasonable basis for an equitable distribution of available SRF funds. Since the St Louis metropolitan area has approximately 20% of the State's population, one can argue that at least 20% of the SRF loans should be concentrated in this region. This would result in a maximum loan amount of approximately $200 million. MSD's current and proposed debt levels are the first components to consider in order to translate the variables outlined above specifically to the District. Footnote # 7 of the District's financial statements included its 2010 CAFR (Exhibit MSD 11A3) begins this translation. As of June 30, 2010 the District had $605 of outstanding long term debt. The composition of the debt was $342 million of stand alone debt and $267 million of SRF debt. Since then the District has borrowed an additional $37 million in SRF debt, repaid $2 million of the stand alone debt and $30 million of the SRF debt. Therefore as of May 31, 2011 the District's total outstanding bonds equaled $610 million comprised of $340 million in stand alone debt and $274 million in SRF debt. In 2012, the District plans to issue approximately $52 million of stand alone debt and another $40 million of SRF debt. As are result, the proposal rate change period begins with approximately $300 million of total SRF debt. In summary there is no set answer. An amount between $200 million and $400 million is reasonable, or between 20% and 40% of the statewide SRF pool. MSD's share of the pool is currently in the middle of that range and has projected growing its relative percentage over the 2013 to 2016 rate cycle. 1-35. Please provide a copy of all workpapers, analyses and studies used to support - 24 - MSD's assumption that future revenue bonds will be issued at an average annual interest rate of 5.50 percent. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: A spreadsheet containing detailed information related to MSD's total outstanding debt as of April 30, 2011, is provided as Exhibit MSD 16A. The average coupon interest rate, per this data, was 5.11%. The 20 year average revenue bond rate is 5.61%. This average rate is based on the Bond Buyer 25 Year Revenue Bond Index provided as Exhibit MSD 16Al2. The Rate Change Proposal (Exhibit MSD 1) assumes a more conservative rate between short term and long term averages of 5.50%. 1-36. Please provide the interest rate, terms and associated issuance costs of MSD issued revenue bonds over the past seven years. RESPONDER: Karl Tyminski, MSD Secretary/Treasurer RESPONSE: All information related to the interest rate, terms and issuance costs of MSD's outstanding revenue bonds is provided as Exhibit MSD 11K through Exhibit 11V. The following questions relate to the direct testimony of Keith D. Barber, MSD Exhibit No. 9F: 1-37. In reference to page 4, response to Q11, Mr. Barber states "almost all of the proposed capital improvement projects are required to be constructed due to Federal and State environmental regulations." Please provide a listing and associated projected dollar costs associated with all proposed capital improvement projects that are not required to be constructed due to Federal and State environmental regulations that are included in MSD's six -year study period. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: All of the proposed capital improvement projects are required due to regulatory requirements. A 5 year CIRP project list is provided as Exhibit MSD 16C. 1-38. Please provide a copy of all workpapers, analyses and studies used to develop the projected number of wastewater customer accounts. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: See responses to Items 1-2b, 1-2i and 1-2j. 1-39. Please provide a copy of all workpapers, analyses and studies used to develop the projected average volume per bill for each metered customer class. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Projected average volume per bill for each metered customer class is available as Pages B-4, B-7 and B-8 of Exhibit MSD 4a. - 25 - 1-40. Please provide a copy of all workpapers, analyses and studies used to develop the projected average volume per bill for each unmetered customer class. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Projected average volume per bill for each metered customer class is available as Pages B-4, B-7 and B-8 of Exhibit MSD 4a. 1-41. In reference to page 14, response to Q44, please provide a copy of all workpapers, analyses and studies used to develop the projected inflation -related cost increases for each year of the six -year study. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Please see response to Item 1-26. 1-42. Please provide a table identifying historical annual costs and inflation cost adjustments during the period 2007 through 2011 associated with: (1) Wages, Salaries and Overtime; (2) Personal Services and Benefits; (3) Group Insurance; (4) Supplies, including chemicals; (5) Electric and Gas; (6) Contractual Services; (7) Bond and Liability Insurance; (8) Capital Outlay; and (9) Pension. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Historical annual costs for the combined wastewater and stormwater operations are presented in Table 2-1 on Page 2-2 of the Wastewater Rate Proposal (Exhibit MSD 1). Detailed historical costs for the combined utilities are available as Pages D-2 through D-7 of Exhibit MSD 4a. Information related to historic wastewater related costs is not available. 1-43. Please identify the current operating reserve level (number of days of expected operating costs) embedded in MSD's current rate levels. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Current operating reserves are set at 60 days of O&M and routine capital costs. 1-44. Please provide an electronic version of the May 5, 2011 MSD wastewater utility cost of service study (in Exhibit MSD 1), with all formulas and file references intact. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: This is regarded by Black & Veatch as proprietary information and not available to third parties. However, all calculation sheets with text formulas showing the basic calculations used and page references are available as Exhibit MSD 4a. In addition, formulas used in the rate model are included in Exhibit MSD 5. - 26 - 1-45. When compared with MSD's cost of service study used in the development of rates in its 2007 rate proceeding, please identify and quantify all customer class allocation differences made in MSD's May 5, 2011 cost of service study. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The methodology used to allocate costs to customer classes in the 2007 rate proceedings is the same methodology used in the current proceedings. The most notable difference is the allocation of environmental compliance costs to non-residential customers. A large portion of the costs recovered only by non-residential customers in the 2007 cost allocations are now recovered from all customers and the costs remaining in the non-residential functional cost component are now recovered on the basis of respective service requirements of five non-residential sub categories instead of a uniform charge. Increased costs and relative changes in customer class units of service will also impact how costs are allocated to the different customer classes. 1-46. Please provide an electronic version of MSD's rate model that supports the wastewater rate proposal, with all formulas and file references intact. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Please see response to Item 1-44. 1-47. In reference to Table 3-23 "Comparison of Wastewater Cost of Service with Revenue Under Proposed Rates Test Year 2013," please provide a detailed description as to why Non -Residential customers' portion of revenue as a percent of cost of service is set at 108.7% while the single family and multifamily portions of revenue levels are set at 96.4% and 97.9%, respectively. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Table 3-18 on Page 3-32 of the Rate Change Proposal (Exhibit MSD 1) indicates that the fiscal year 2013 cost of service increase over approved 2012 rates for non-residential customers is a negative 0.9 percent. This compares to an overall revenue increase of 11 percent for the system, 16.6 percent for single family customers and 15.7 percent for multifamily customers. This is due to the reallocation of costs formerly recovered only from non-residential customers through the environmental compliance charge to other cost components that are recovered by all customer classes. The indicated revenue increases are based on an immediate transition to cost of service in 2013. In contrast, the revenue as a percent of cost of service values shown in Column 3 of Table 3-23 show the proposed first year transition of the five -tier environmental compliance charge where Tiers 2 through 5 are immediately set at cost of service levels but the proposed charge for Tier 1 customers is lowered from the 2012 approved compliance charge but over recovers costs based on the revised cost allocation. This provides some relief to residential customers as the - 27 - Tier 1 compliance charge moves towards the indicated cost of service rate in 2016. The table below shows indicated cost recovery in 2016 when Tier 1 rates are fully transitioned to cost of service charges. See table on next page.

Please confirm that under MSD's rate proposal, the rates of MSD's non-residential customers would be set above cost of service while the rates of MSD's single family and multifamily customers would be set below cost of service. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Please see response for Item 1-48. - 28 - 1-49. Please provide MSD's basis for setting the rates of MSD's non-residential customers above cost of service. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Please see response for Item 1-48. The basis is to provide a four-year transition of Tier 1 rates so as to realign costs from the current uniform compliance charge to a reduced Tier 1 charge due to the reallocation of compliance related costs from only the non-residential customer class to all customer classes. 1-50. At page 17 of Mr. Barber's testimony, he states that certain operation, maintenance and construction improvement funds are not included in wastewater capital improvement financing plans since these funds are supported by ad valorem taxes from various districts and dedicated to local area projects. Please identify the exact amount of revenue MSD receives from ad valorem taxes from these districts, and the operation, maintenance and construction improvement funds and expenditures made for these districts. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Historically, the District has maintained two OMCI subdistricts solely dedicated for wastewater related capital improvements: Missouri River - Bonfils (Fund 5590) and the Lower Meramec River Basin (Fund 5591). At this time, taxes are not being assessed in these areas and only residual balances are maintained in each subdistrict fund. Per the 2012 Budget (Exhibit MSD 8, Pages 116 & 117), Missouri River - Bonfils is expected to have an end of year 2011 balance of $3,581,000 and the Lower Meramec River Basin is projected to have a 2011 end of year balance of $6,318,000. 1-51. Referring to page 19 of Mr. Barber's testimony, please provide all workpapers used to develop the debt service coverage ratios calculated at lines 2-10 of that testimony. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Debt service calculations are shown on Lines 35 and 36 of Table 3-11 from Page 3-18 of Exhibit MSD 1. The values on Line 35 are the result of dividing Line 18 by line 33 and the values on Line 36 are the result of dividing Line 18 by the sum of Lines 33 and 34 of Table 3-11. 1-52. Concerning the debt service coverage ratios developed on page 19, please state whether or not the ad valorem tax revenue receipts referred to at page 17 net of operation, maintenance and construction improvement expenditures are included in the development of debt service coverage ratios. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Tax revenues are solely related to the District's stormwater program which is not a component of the current Rate Change Proposal (Exhibit MSD 1). As such, tax revenue is not used in the debt service calculations. - 29 - 1-53. Referring to page 19, Mr. Barber states that the forecast includes $945 million of additional bond authorizations based on a 30 -year term and an interest rate of 5.5%. Please provide all supporting documentation relied on by Mr. Barber to estimate the 5.5% interest rate on tax-exempt municipal bond issuances. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Historic interest rates can be obtained from the Bond Buyer 25 -Year Revenue Bond Index (Exhibit MSD 16A). Based on this information, a reasonable estimate for future debt was determined to be 5.5 percent. See response to Q 1 — 35 for more information. 1-54. Referring to page 19 of Mr. Barber's testimony, please provide all supporting documentation describing the State Revolving Fund loans, interest rates and maturities used in the forecast. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Please see response for Item 1-2d. 1-55. Concerning page 19 of Mr. Barber's testimony, please describe the commercial paper program, provide support for the assumed 5% interest rates and issuance costs of $25,000 per issue. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Although the ability to issue commercial paper has been provided for in the rate model, no commercial paper is expected to be issued during the study period. 1-56. Referring to page 19 of Mr. Barber's testimony, please provide a detailed report describing how the targeted minimum debt service coverage ratios of senior and junior lien bonds of 220% and 150% were developed. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: These values were suggested by the District's financial advisors to help maintain the District's credit rating and provide reasonable assurances that the rate covenant and additional revenue bond coverage tests can be consistently met. 1-57. Referring to page 21 of Mr. Barber's testimony, please provide a copy of financial reports from MSD supporting the beginning of Fiscal Year 2011 fund balances. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The wastewater fund balance as of June 30, 2010 is determined on Page G-8 of Exhibit MSD 4a. The source document for these values is attached as Exhibit MSD 16A13. 1-58. Referring to pages 14 and 15 of Mr. Barber's testimony, please provide all supporting documentation used to develop the inflation rates for each of the O&M - 30 - expense items included at those pages. Please also provide a narrative explaining how the escalation rates were derived. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: See responses to Items 1-26 and 1-27. 1-59. Referring to page 27 of Mr. Barber's testimony, he states that certain wholesale customers may own and operate their own sewer collection system and may not be responsible for the smaller mains serving the utility's retail customers. With respect to this testimony, please answer the following: a. Are the larger mains serving wholesale customers connected to the smaller mains serving retail customers? RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: No, typically large mains from a wholesale customer connect directly to large mains of the utility providing service to the wholesale customer. The District currently serves the City of Arnold on a wholesale basis. By contract (Exhibit MSD 11X), the City of Arnold is charged for O&M costs based on their relative portion of wastewater contributed to the Lower Meramec Treatment Plant in addition to the loan repayment currently being paid to MSD for a share of the treatment plant's capacity. b. If the larger mains serving wholesale customers are connected to the smaller mains serving retail customers, why shouldn't wholesale customers pay a portion of those smaller mains? RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: For utilities that serve wholesale customers, where the wholesale customer is typically a municipality, the wholesale customer maintains its own sewer lines serving its customers within its city limits and typically sends it wastewater through large interceptor sewers to the contracting utility's interceptor sewer system for eventual treatment and disposal. The City of Arnold owns and maintains all sewer lines serving its customers. These lines are connected to a larger main that flows to the Lower Meramec Treatment Plant. In this case, due to Arnold's southern location, Arnold's interceptor goes directly to the treatment plant and is not connected to the District's interceptor sewer system as would typically occur as described above. 1-60. Is excluding an allocation of small main costs to wholesale customers, because they own their own sewer collection system, consistent with the Water Environment Federation (WEF) in its "Financing and Charges for Wastewater -31 - Systems" manual as identified by Mr. Barber at page 25 of his testimony? Please explain answer. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Yes, pages 160 — 161 of the WEF manual states: "if the wholesale customer owns and operates its own collection system and provides its own billing services, it should only be billed for transporting the wastewater from the connection point to the treatment plant and for handling and treating the wastewater." Wholesale customers typically own and maintain sewer lines serving their customers within their jurisdiction. Therefore, these customers typically only share in large sewer mains and treatment facilities owned and operated by the contracting wastewater utility. 1-61. Referring to page 28, please explain how I/I is allocated on both customer and volume basis in the rate manual in order to equitably allocate costs between customer classes. Please also identify where in the cost allocation component of the rate filing this I/I customer/volume allocation is made. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: An explanation of allocated I/I is provided on Page 3-28 of the Wastewater Rate Proposal (Exhibit MSD 1). A detailed allocation of I/I is provided on Page J-5 of Exhibit MSD 4a. This methodology is consistent with recovery methods allowed by Federal user charge requirements as mirrored 011 Page 132 of the WEF manual. In addition, the WEF manual states on Page 132 that: "The most common approaches have been to use contributed wastewater flow, the number of connections (or customers), or a combination of the two to allocate I/I related costs." 1-62. Referring to pages 28 and 29 of Mr. Barber's testimony, please identify the specific costs related to reviewing environmental compliance with specified pollutants identified by the EPA, and which were used to identify the tier ratio rate schedule proposed by MSD in this proceeding. Please provide a complete description of all cost elements, a billing unit breakdown for the tiered approach, and number of customers under each of the tier stacking procedure. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Costs are not specific to pollutants. EPA maintains a list of pollutants that may be contributed or stored on -site by various industrial users which could result in an industrial user being classified as a categorical industrial user. Information concerning the proposed compliance charge is available on Pages 3-37 and 3-38 of Exhibit MSD 1. - 32 - 1-63. Please provide a complete copy of the January 2005 CDM study included in the 2007 wastewater/storm water rate proposal as referenced at page 31 of Mr. Barber's testimony. RESPONDER: Jan Zimmerman, MSD Director of Finance RESPONSE: A copy of the January CDM Wet Weather Study is provided as Exhibit MSD 16A14. 1-64. Please provide a copy of all workpapers and supporting documents used to develop the capacity factors for contributed wastewater and infiltration and inflow volume stated at page 33 of Mr. Barber's testimony. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: The calculations used to develop the requested capacity factors stated in Q101 on Page 33 of the referenced testimony are based on prior analyses not readily available. The application of these factors is presented on Page J-7 of Exhibit MSD 4a. 1-65. Please provide copies of all resource documents and other supporting information used to determine whether or not the proposed wastewater rates are reasonably affordable for the ratepayers as discussed at page 36 and Q&A109 of Mr. Barber's testimony. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Affordability considerations are discussed in Section 5.6 of the wastewater Rate Proposal (Exhibit MSD 1, Pages 5-11 & 5-12). 1-66. Referring to page 36, Q110 of Mr. Barber's testimony, please identify all quantitative support for Mr. Barber's contention that his proposed wastewater rates were designed to recover costs of providing wastewater service. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: Quantitative support for recovery of costs to provide wastewater service is presented in the Rate Change Proposal (Exhibit MSD 1) in its entirety. The methodology presented in Exhibit MSD 1 is consistent with standard industry practice and all prior Rate Commission proceedings. 1-67. Referring to pages 38 and 39 of Mr. Barber's testimony, please provide complete copies of all supporting documentation supporting his contention that the MSD's - 33 - surcharges are comparable with rates currently charged by Kansas City, Missouri, and also provide copies of surcharge rate comparisons with any other wastewater system. RESPONDER: Keith Barber, MSD Rate Consultant RESPONSE: All Kansas City ordinances are available online at the City's web site (www.kcmo.org), including the referenced Ordinance 110167. A survey of excess strength charges levied by other wastewater utilities was not conducted as part of this rate change proposal. Respectfully submitted, Susan Myers, General Counsel ME 1ROPOLITAN ST.
