Appendix A Exhibits Nos. 419 & 420 York, Di 1 Micron Technology, Inc. Q PLEASE STATE YOUR NAME AND BUSINESS ADDRESS. 1 A Jessica A. York. My business address is 16690 Swingley Ridge Road, Suite 140, 2 Chesterfield, MO 63017. 3 Q WHAT IS YOUR OCCUPATION? 4 A I am a consultant in the field of public utility regulation and an Associate at 5 Brubaker & Associates, Inc., energy, economic and regulatory consultants. 6 Q PLEASE DESCRIBE YOUR EDUCATIONAL BACKGROUND AND 7 EXPERIENCE. 8 A This information is included in Appendix A to my testimony. 9 Q ON WHOSE BEHALF ARE YOU APPEARING IN THIS PROCEEDING? 10 A I am appearing on behalf of Micron Technology, Inc., a large customer of Veolia 11 Water Idaho Inc. (“Veolia,” “VWID,” or “the Company”). 12 Q WHAT IS THE PURPOSE OF YOUR TESTIMONY? 13 A The purpose of my testimony is to address the Company’s class cost of service 14 study (“COSS”), proposed revenue apportionment, base rate design, and 15 proposed Distribution System Improvement Charge (“DSIC”). My silence with 16 respect to any issues addressed by any other party’s testimony in this proceeding 17 should not be taken as tacit approval or agreement regarding those issues. 18 York, Di 2 Micron Technology, Inc. I. SUMMARY Q PLEASE SUMMARIZE YOUR CONCLUSIONS AND RECOMMENDATIONS. 1 A My conclusions and recommendations are as follows: 2 • The Company’s COSS follows the generally accepted Base-Extra Capacity 3 cost allocation method, which is a reasonable approach. However, the 4 Company’s COSS needs to be modified to improve the accuracy of the 5 measurement of its cost of providing service to each customer class. 6 o Specifically, the Company’s COSS does not recognize the fact that some 7 large customers are connected directly to transmission mains, and do not 8 utilize the smaller distribution mains. An adjustment should be made to the 9 allocation factors used for distribution main cost allocation for each class 10 to reflect this distinction in the infrastructure used to provide service. 11 • The Company’s proposed revenue apportionment should be rejected, as it 12 does not make a meaningful movement toward cost of service for each 13 customer class, and continues the interclass subsidies that have existed for 14 years. 15 o I recommend an alternative revenue apportionment where all classes are 16 brought to cost of service in this case, subject to the limitation that no class 17 receives an increase greater than 1.25x the system average increase. Any 18 remaining revenue deficiency can be spread to classes that would receive 19 a rate change below the system average, in proportion to each of the non-20 capped class’s total cost of service. 21 • The Company has not adequately supported the continuation of its existing 22 inclining block volumetric rate structure. I recommend the Commission direct 23 the Company to develop and present a declining block volumetric rate structure 24 in the next rate case. 25 • I recommend that the Company’s tariffs be modified to provide an economic 26 development rate, and/or to allow for service to be provided under a special 27 contract for certain qualifying customers. 28 • I recommend the Commission reject the Company’s proposed DSIC 29 mechanism. But, if the Commission adopts the Company’s proposed DSIC 30 mechanism, I recommend that the proposed DSIC be modified to track 31 changes in total net-plant investment related to the replacement and/or 32 rehabilitation of distribution system transmission and distribution mains, 33 services, hydrants, valves, meters and other infrastructure, and should not 34 track only incremental plant investments. Also, if the DSIC is adopted, it should 35 account for not only incremental rate base changes resulting from investments 36 made under the rider, but should also account for the change in legacy net-37 plant or rate base value during post-test year periods. 38 York, Di 3 Micron Technology, Inc. II. CLASS COST OF SERVICE STUDY 1 Q HAVE YOU REVIEWED THE COMPANY’S CLASS COST OF SERVICE 2 STUDY? 3 A Yes. The Company’s COSS is sponsored by Ms. Ann Bui. Her COSS is based 4 on the test year ended March 31, 2023, and uses the widely accepted Base-Extra 5 Capacity method for functionalizing, classifying and allocating costs to VWID’s 6 various customer classes. Investment in water utility plant and operating costs are 7 first functionalized according to the role they play in providing water service: water 8 supply, pumping, treatment, transmission, distribution, metering, and billing. Next, 9 these costs are classified into cost categories that reflect the causation of these 10 costs: Base, or average day rates of flow; Extra Capacity-Maximum Day and Extra 11 Capacity-Maximum Hour rates of flow; and Customer-related costs, such as 12 metering and billing. 13 Q IS THE COMPANY’S COSS REASONABLE? 14 A In general, the Base-Extra Capacity cost allocation method is a reasonable 15 approach to cost allocation. However, the Company’s COSS does not accurately 16 measure the cost of providing service to each customer class. Therefore, it should 17 not be relied upon as the basis for revenue apportionment in this proceeding. 18 Q WHY DO YOU BELIEVE THAT THE COMPANY’S COSS DOES NOT 19 ACCURATELY MEASURE ITS COST OF PROVIDING SERVICE TO EACH 20 CUSTOMER CLASS? 21 A There are two reasons. First, the Company initially made an error when allocating 22 depreciation expense and rate base investment associated with Transmission and 23 York, Di 4 Micron Technology, Inc. Distribution (“T&D”) Mains and Accessories. This error overstates VWID’s cost to 1 serve the Commercial class and understates the cost to serve Residential 2 customers. As discussed below, the Company acknowledged this error in 3 discovery and an adjustment has been made to reflect the correction. 4 Second, certain large customers are connected directly to VWID’s large 5 transmission mains, and therefore do not use and should not be allocated the costs 6 associated with the smaller distribution mains. However, there is no distinction in 7 the allocation of distribution mains costs to reflect this reality. As a result, the 8 Company’s COSS over-allocates distribution costs to customers that do not use 9 smaller distribution mains. 10 I discuss each of these reasons in further detail below. 11 II.A. VWID’s Error in the Allocation of T&D Mains and Accessories 12 Q PLEASE DISCUSS THE COMPANY’S ALLOCATION OF COSTS ASSOCIATED 13 WITH TRANSMISSION AND DISTRIBUTION MAINS AND ACCESSORIES. 14 A In the COSS included as Exhibit 14-2 to Ms. Bui’s direct testimony, transmission 15 and distribution costs were not separated by main size, and instead were lumped 16 together in one category. As shown on Bui Exhibit 14-2, page 5 of 40, O&M 17 expenses associated with T&D mains are allocated using Factor 6, which is 18 appropriate for these expenses because it reflects a base, maximum day, 19 maximum hour, and fire protection component. While the Company had correctly 20 allocated the O&M expenses associated with T&D mains on Factor 6, it did not 21 correctly allocate the corresponding plant investment in T&D mains, or the 22 associated depreciation expense. 23 York, Di 5 Micron Technology, Inc. Q PLEASE DISCUSS THE COMPANY’S ALLOCATION OF DEPRECIATION 1 EXPENSE AND PLANT INVESTMENT ASSOCIATED WITH T&D MAINS. 2 A The Company allocated the depreciation expense associated with T&D Mains and 3 Accessories using Factor 3.1 Similarly, the Company allocated the T&D Mains and 4 Accessories rate base using Factor 3.2 5 Factor 3 includes a base, maximum day demand, and fire protection 6 component. However, unlike Factor 6, it does not reflect a maximum hour extra 7 capacity demand component, and therefore does not accurately allocate the 8 distribution main-related expenses and rate base that are included in these line 9 items of the COSS. 10 Q DID YOU SUBMIT A DISCOVERY REQUEST TO THE COMPANY REGARDING 11 THIS ISSUE? 12 A Yes. Micron’s Discovery Request No. 47 to VWID raised questions about these 13 allocations.3 In response to this request, the Company acknowledged that its 14 original proposed allocations were in error.4 In addition, the Company provided a 15 corrected version of its COSS model and exhibits with that discovery response. 16 The Company has now correctly separated T&D plant investment and expenses 17 in its COSS, and allocated transmission costs using Factor 3, and distribution costs 18 using Factor 6. 19 1 Exhibit 14-2, Page 8 of 40. 2 Id.at 10. 3 Attached as Exhibit No. 419, pp. 1-29. 4 Id. York, Di 6 Micron Technology, Inc. Q WHAT WAS THE IMPACT OF THIS CORRECTION ON THE COMPANY’S 1 COSS RESULTS? 2 A A comparison of VWID’s original COSS results to its corrected COSS results is 3 presented below in Table 1. 4 As can be seen from the Table 1, this error was overstating VWID’s cost to serve 5 the Commercial class by $545,4525, and understating the cost to serve Residential 6 customers by about $469,031.6 7 While VWID acknowledged and corrected this error, the issue of the 8 distinction in main size used to serve some large customers must be resolved in 9 order to produce a more accurate measure of the cost of providing service to each 10 customer class. 11 5 $2,726,433 - $3,271,885 = $545,452. 6 $10,146,076 - $9,677,046 = $469,031.

Certain Large Customers Do Not Use the Distribution System 1 Q HOW DOES THE COMPANY DISTINGUISH TRANSMISSION MAINS FROM 2 DISTRIBUTION MAINS INSTALLED IN ITS SYSTEM? 3 A The Company defines transmission mains as those that have diameters of 12-4 inches and larger.7 VWID defines distribution mains as those with diameters of 5 less than 12-inches.8 6 Q HAS THE COMPANY ACKNOWLEDGED THAT SOME LARGE CUSTOMERS 7 DO NOT TAKE SERVICE FROM SMALL DISTRIBUTION MAINS, BECAUSE 8 THEY ARE CONNECTED DIRECTLY TO TRANSMISSION MAINS? 9 A Yes. The Company has acknowledged that there are at least two 8-inch meters 10 that are served from transmission mains.9 One meter is associated with a 24-inch 11 diameter main, and the other is associated with a 12-inch diameter service line.10 12 It is my understanding that Micron takes service directly from transmission mains 13 as well. 14 Q DOES THE COMPANY’S ALLOCATION OF COSTS ASSOCIATED WITH 15 DISTRIBUTION MAINS REFLECT THE FACT THAT SOME CUSTOMERS DO 16 NOT TAKE SERVICE FROM DISTRIBUTION MAINS? 17 A No. As a result, the Company’s COSS allocates distribution costs to customers 18 that are connected directly to the transmission system, and that do not take service 19 from the smaller distribution mains. This does not accurately reflect cost causation 20 7 VWID’s Response to Micron’s Discovery Request No. 17, attached as Exhibit No. 419, p. 30. 8 VWID’s Response to Micron’s Discovery Request No. 18, attached as Exhibit No. 419, p. 31. 9VWID’s Response to Micron’s Discovery Request No. 7, attached as Exhibit No. 419, p. 32. 10 Id. York, Di 8 Micron Technology, Inc. and is inequitable to large customers that are connected directly to the 1 transmission mains. 2 Q DO WATER UTILITIES IN OTHER JURISDICTIONS RECOGNIZE THE 3 DISTINCTION IN MAIN SIZE USED TO PROVIDE SERVICE IN THEIR COSS 4 MODELS? 5 A Yes. Several subsidiaries of American Water Works Company reflect such a 6 distinction in their COSS models, including Virginia-American Water Company 7 (Virginia State Corporation Commission (“VSCC”) Docket No. PUR-2021-00255), 8 Illinois-American Water Company (Illinois Commerce Commission (“ICC”) Docket 9 No. 22-0210), Indiana-American Water Company (Indiana Utility Regulatory 10 Commission (“IURC”) Cause No. 45142), and Missouri-American Water Company 11 (Missouri Public Service Commission (“MPSC”) Case No. WR-2022-0303). The 12 distinction in main size is appropriate based on cost causation principles and has 13 been agreed to by parties, or approved for use by these various state 14 Commissions. 15 Q HOW SHOULD THE DISTINCTION IN MAIN SIZE USED TO SERVE 16 CUSTOMERS BE REFLECTED IN THE COSS MODEL? 17 A The best approach is to establish a separate class in the COSS and for rate design 18 purposes for large customers that take service directly from transmission mains 19 and do not use the smaller distribution mains. The Commission should direct the 20 Company to create this separate class in the COSS for the next rate case. 21 In the meantime, an alternative approach would be to make an adjustment 22 to the allocation factors used to allocate distribution main costs to reflect the fact 23 that some customers do not use the distribution mains. 24 York, Di 9 Micron Technology, Inc. As an example, Missouri-American Water Company recognizes that there 1 are some customers in the commercial, industrial, and public authority classes that 2 are connected directly to the transmission system, and do not use the small 3 distribution mains. Therefore, it has historically reduced the amount of water 4 consumption used to develop its distribution cost allocation factors for these 5 classes. 6 For its Industrial class, Missouri-American Water Company has historically 7 relied on an analysis of the length of small distribution mains serving Industrial 8 customers as a fraction of the total distribution main installed on the system and 9 concluded that the Industrial units of service should be reduced by 90% in the 10 development of its distribution cost allocation factors for that class.11 11 In other jurisdictions, utilities are estimating the portion of water 12 consumption in the non-residential classes served directly from the transmission 13 system, and removing that portion of usage from an allocation of distribution 14 costs.12 While I do not agree with developing customer class distribution 15 multipliers strictly based on water usage, this approach could be used to improve 16 the accuracy in the measurement of VWID’s COSS in the instant case, while the 17 Company conducts a more detailed review of this issue prior to the next rate case. 18 11MPSC Case Nos. WR-2008-0311, WR-2017-0285, WR-2020-0344. MPSC Staff proposed to continue the same distribution multiplier in WR-2022-0303. 12 VSCC Docket No. PUR-2021-00255, Direct Testimony of Charles Rea at 48. ICC Docket No. 22- 0210, Direct Testimony of Charles Rea at 47. IURC Cause No. 45142, Direct Testimony of Constance Heppenstall at 10-11. York, Di 10 Micron Technology, Inc. Q ARE YOU RECOMMENDING A MODIFICATION TO THE COMPANY’S COSS 1 TO RECOGNIZE THE DISTINCTION IN SIZE OF MAINS USED TO SERVE 2 VARIOUS CUSTOMERS? 3 A Yes. I recommend the Commission direct VWID to recognize the fact that some 4 large customers take service directly from the transmission system, and therefore 5 should not be allocated costs associated with the smaller distribution mains that 6 are not used to provide service to them. I recommend that for the next rate case, 7 the Commission direct VWID to create a separate class in the COSS model and 8 for rate design for customers that are served directly from the transmission mains. 9 However, for purposes of this case, VWID should recognize this distinction 10 in the infrastructure used to provide service by developing a distribution multiplier 11 to remove the units of service that are not served by the distribution system from 12 the development of distribution main cost allocation factors by class. At this time, 13 VWID has not provided the data necessary for Micron to make a specific proposal 14 as to what distribution multipliers would be appropriate for each class. However, 15 at a minimum, allocation factors should be adjusted such that the test year units of 16 service for the two 8-inch meters identified by VWID in response to Micron’s 17 Discovery Request No. 7 are removed from an allocation of distribution costs. 18 III. REVENUE APPORTIONMENT 19 Q PLEASE DISCUSS THE COMPANY’S PROPOSED REVENUE 20 APPORTIONMENT. 21 A The Company’s proposed revenue apportionment does not reflect its actual cost 22 to serve each customer class, as demonstrated by its COSS. A comparison of the 23 York, Di 11 Micron Technology, Inc. Company’s proposed revenue apportionment to its COSS results is presented in 1 Table 2. 2 As shown above in the Table 2, the Company proposes no rate change for the 3 Private Fire class, despite the fact that the COSS shows a rate decrease is 4 warranted. The Company proposes to spread the remaining revenue deficiency 5 on an equal percentage basis across the Residential, Commercial, and Public 6 Authority classes, even though the COSS results do not support an equal 7 percentage increase. 8 Q IS THE COMPANY’S PROPOSED REVENUE APPORTIONMENT 9 REASONABLE? 10 A No. The Company’s proposed revenue allocation does not make meaningful 11 movement toward cost of service for all customer classes. Indeed, the Company’s 12 proposed revenue allocation maintains rates that are below cost of service for the 13 Current Line Customer Class Revenues Amount Percent Amount Percent (1)(2)(3)(4)(5) 1 Residential 35,139,116$ 10,146,076$ 28.9%8,451,646$ 24.1% 2 Commercial 15,042,723 2,726,433 18.1%3,618,134 24.1% 3 Public Authority 155,695 9,638 6.2%37,448 24.1% 4 Private Fire 1,344,703 (774,918) -57.6%- 0.0% 5 Total 51,682,238$ 12,107,228$ 23.4%12,107,228$ 23.4% Source VWID's revised cost of service study provided in response to Micron Data Request No. 47. Cost of Service Increase / (Decrease) TABLE 2 Veolia Water Idaho Inc. Cost of Service vs. Proposed Revenue Allocation Increase / (Decrease) to Reach VWID Proposed York, Di 12 Micron Technology, Inc. Residential class, and significantly above cost of service for all other classes 1 perpetuating existing cross-subsidies among rate classes. Further, the 2 Company’s proposed revenue apportionment is based on a COSS model that does 3 not accurately reflect its cost of providing service to its customers, as further 4 discussed above. Finally, an across-the-board increase has been applied in the 5 last several VWID rate cases, which suggests that there has been essentially no 6 movement toward cost of service for years. As a result, I recommend that the 7 Company’s proposed revenue allocation be rejected. 8 Q HOW LONG HAVE INTERCLASS SUBSIDIES EXISTED FOR VWID’S 9 CUSTOMERS? 10 A The subsidies have existed since at least the 2006 rate case, when VWID was still 11 United Water. Despite the COSS results presented in each rate case, the 12 Commission approved settlement agreements that resulted in an equal percent 13 increase for all customer classes in the 2006, 2009, 2015, and 2020 rate cases.13 14 In the 2011 rate case, a slightly different approach was taken where the parties 15 agreed to a two-step phase-in of the rate increase.14 16 Q HAS THE COMMISSION PREVIOUSLY RECOGNIZED THE IMPORTANCE OF 17 MOVING CUSTOMER CLASS RATES CLOSER TO COST OF SERVICE? 18 A Yes. In a previous Idaho Power Company rate case, the Commission noted the 19 following: 20 “Nonetheless, the passage of time since the Commission’s last 21 examination of IPCo’s rates has allowed several classes to drift 22 further away from cost-of-service rates. Recognizing that cost-of-23 13 See Settlement Agreement and Orders in Dockets UWI-W-06-02, UWI-W-09-01, UWI-W-15-011, and SUZ-W-20-02. 14 See Settlement Agreement and Order in Docket UWI-W-11-2. York, Di 13 Micron Technology, Inc. service studies are not precise, we think it is important that cross 1 subsidies among customer classes should be minimized. 2 Accordingly, as outlined below, we take significant steps to move 3 each class closer to its indicated cost of service.”15 4 Q ARE YOU RECOMMENDING AN ALTERNATIVE REVENUE 5 APPORTIONMENT? 6 A Yes. I recommend bringing each class to cost of service in this case, based on 7 my recommended corrections to the Company’s COSS model discussed above, 8 with the limitation that no class receive an increase greater than 1.25x the system 9 average increase. Any remaining revenue deficiency could be spread to classes 10 that would receive a rate change that is less than the system average percentage 11 increase, in proportion to each non-capped class’s allocated cost of service. 12 An example of this proposed revenue allocation is shown in Table 3 below. 13 For illustrative purposes, Table 3 assumes that my recommended correction to the 14 allocation of distribution main costs would show that the Residential class requires 15 a 1.26x system average increase to reach cost of service. However, the actual 16 impact will need to be determined by VWID, and may not create a need for any 17 class to be capped.16 18 15 Idaho Public Utilities Commission Case No. IPC-E-94-5; Order No. 25880 at 20. 16 The Company’s COSS shows that the Residential class needs a 1.23x system average increase to reach cost of service. If my recommended correction to the COSS does not increase this index above 1.25x, then no cap would be needed. York, Di 14 Micron Technology, Inc. Table 4, below, shows the results of the revenue apportionment presented in 1 Table 3 based on Mr. Gorman’s recommended revenue increase of $6.4 million, 2 or 12.4%. 3 Current Line Customer Class Revenues Amount Percent Index Amount Percent Index (1)(2)(3)(4)(5)(6)(7) 1 Residential 35,139,116$ 10,396,076$ 29.6%1.26 10,289,737$ 29.3%1.25 2 Commercial 15,042,723 2,476,433 16.5%0.70 2,578,490 17.1%0.73 3 Public Authority 155,695 9,638 6.2%0.26 10,601 6.8%0.29 4 Private Fire 1,344,703 (774,918) -57.6%(2.46) (771,599) -57.4%(2.45) 5 Total 51,682,238$ 12,107,228$ 23.4%1.00 12,107,228$ 23.4%1.00 Note: *For illustrative purposes, this example assumes that Micron's recommended corrections to the allocations of distribution main costs would show that the Residential class requires an increase of 1.26x system average to reach cost of service.

Existing Volumetric Block Rate Structure 4 Q PLEASE DISCUSS VWID’S CURRENT RATE STRUCTURE. 5 A Currently, VWID has a rate structure that consists of a fixed meter charge by size, 6 and volumetric charges that vary by season. For the winter period from October 7 through May, a single flat volumetric rate per hundred cubic feet (“CCF”) applies. 8 The summer period consists of two volumetric rate blocks where the first block is 9 priced at the same rate as the winter period and captures the first 3 CCF of usage. 10 The second summer rate block captures all additional CCF and is more expensive 11 than the first block. 12 This rate structure applies to all customer classes. 13 Current Line Customer Class Revenues Amount Percent Index Amount Percent Index (1)(2)(3)(4)(5)(6)(7) 1 Residential 35,139,116$ 5,495,468$ 15.6%1.26 5,439,256$ 15.5%1.25 2 Commercial 15,042,723 1,309,067 8.7%0.70 1,363,015 9.1%0.73 3 Public Authority 155,695 5,095 3.3%0.26 5,604 3.6%0.29 4 Private Fire 1,344,703 (409,630) -30.5%(2.46) (407,875) -30.3%(2.45) 5 Total 51,682,238$ 6,400,000$ 12.4%1.00 6,400,000$ 12.4%1.00 Note: *For illustrative purposes, this example assumes that Micron's recommended corrections to the allocations of distribution main costs would show that the Residential class requires an increase of 1.26x system average to reach cost of service.

Example Revenue Apportionment Limiting the Residential Class to 1.25x System Average Example Increase / (Decrease) Needed to Mitigated Proposed at Mr. Gorman's Recommended Revenue Requirement York, Di 16 Micron Technology, Inc. Q HAS VWID PROPOSED ANY CHANGES TO ITS EXISTING RATE 1 STRUCTURE? 2 A No. VWID proposes to maintain the existing rate structure, with all rate 3 components increased by an equal percentage to recover the Company’s 4 requested revenue requirement. 5 Q HAS THE COMPANY EXPLAINED WHY IT BELIEVES IT IS REASONABLE TO 6 MAINTAIN ITS INCLINING BLOCK RATE STRUCTURE? 7 A No. The Company’s testimony does not specifically address this issue. 8 Q DO YOU HAVE ANY CONCERNS WITH THE COMPANY’S INCLINING BLOCK 9 VOLUMETRIC RATE STRUCTURE? 10 A Yes. First, if the purpose of this rate structure is to promote water conservation, it 11 is not clear that the existing rate structure accomplishes this objective. The first 12 summer rate block captures the first 3 CCF, or about 2,200 gallons, of usage. For 13 the Residential class, only about 6% of summer usage falls into the first block with 14 the remaining 94% in the second, more expensive block.17 For the Commercial 15 class, the first summer block captures about 2% of the summer water usage, and 16 98% falls into the second block.18 Thus, since the second block is essentially 17 unavoidable, this rate structure does little or nothing to encourage customers to 18 use less water during the higher priced summer period. 19 Second, under the Company’s existing volumetric rate structure, 20 customers with seasonal water use may not be making a great enough contribution 21 to the Company’s recovery of fixed costs during the non-summer months. As a 22 17 VWID’s workpaper WP 14.6, Proof of Revenue. 18 Id. York, Di 17 Micron Technology, Inc. result, large water customers with relatively steady water use year-round may be 1 subsidizing customer classes with seasonal peak water demands. 2 In addition, an inclining block rate structure could inhibit economic 3 development by deterring potential new large water users from locating in the 4 Company’s service territory or deter existing large water users from expanding 5 operations. 6 A declining block volumetric rate structure that primarily targets fixed cost 7 recovery in the more expensive first blocks, and volumetric cost recovery in the tail 8 block would be more appropriate. In the event that the Commission determines it 9 is appropriate to maintain a single rate structure for all customer classes, then a 10 declining block rate design could be used to more closely align rates with the cost 11 of providing service to each class and support economic development. The 12 Company should be directed by the Commission to explore a new rate structure 13 prior to its next rate case or provide evidence explaining why its proposal to 14 maintain the existing volumetric rate structure is just and reasonable. 15 IV.B. Large Customer Rate Options 16 Q ARE THERE ANY OTHER RATE DESIGN ISSUES THAT YOU WOULD LIKE 17 TO RAISE? 18 A Yes. The Company’s current COSS and rate design do not separately identify an 19 Industrial class, as the Company claims that no customers currently meet its 20 definition of an Industrial customer. As noted by Ms. Bui, the Company’s current 21 tariff includes an Industrial classification, but no active customers are in this 22 class.19 Further, in response to a discovery request from Staff, the Company 23 19 Bui, Appendix B at 8. York, Di 18 Micron Technology, Inc. claimed that based on the Company’s existing definition of Industrial customers, 1 no customers currently meet this definition.20 2 Q WHAT IS THE COMPANY’S CURRENT DEFINITION OF AN INDUSTRIAL 3 CUSTOMER? 4 A The Company’s tariff defines an industrial customer as follows: 5 “Industrial customer shall designate any building or combination of 6 buildings in the same compound whose primary use is for the 7 manufacture, fabrication, and/or assembly of any product.”21 8 Q DOES MICRON FIT WITHIN THE DEFINITION OF AN INDUSTRIAL 9 CUSTOMER? 10 A According to the Company, Micron does not currently fit the definition of an 11 Industrial customer. VWID indicates that currently Micron’s water use is primarily 12 for office space and private fire protection, and therefore it fits the definition of a 13 Commercial customer.22 14 Q SHOULD THE DEFINITION OF AN INDUSTRIAL CUSTOMER BE TIED TO THE 15 PURPOSE FOR WHICH WATER IS USED? 16 A No. The definition of customer classes should take into consideration load 17 characteristics and the infrastructure used to provide service. The purpose for 18 which water is used is not relevant. 19 20 VWID’s Response to Staff’s Discovery Request No. 154, attached as Exhibit No. 419, p. 34. 21 Sheet No. 36 of the Company’s Current Tariff, attached as Exhibit No. 420. 22 VWID’s Response to Micron’s Discovery Request No. 42, part c (ii), attached as Exhibit No. 419, pp. 35-37. York, Di 19 Micron Technology, Inc. Q IS MICRON EXPECTED TO FIT WITHIN VWID’S DEFINITION OF AN 1 INDUSTRIAL CUSTOMER IN THE FUTURE? 2 A Yes. It is public knowledge that Micron is doing a major expansion in Boise, Idaho. 3 Indeed, Micron has announced plans to invest about $15 billion through the end of 4 the decade in advanced memory manufacturing in Boise.23 Construction is 5 expected to begin in 2023 with production beginning in 2025.24 Micron’s expansion 6 will include a water treatment facility to ensure incoming water meets high-purity 7 specifications for manufacturing.25 Water sources will include on-site groundwater 8 and service from Veolia.26 Water will be a crucial element to Micron’s 9 manufacturing process, and its water consumption is expected to increase 10 significantly when operations commence. Thus, Micron will require industrial use 11 water from VWID. 12 In addition, Micron’s expansion is expected to create over 17,000 Idaho 13 jobs, including 2,000 direct Micron jobs.27 Micron also intends to increase 14 investment in K-12 STEM education programs, build on partnerships with 15 community colleges and universities, and identify new ways to provide education 16 and training to underrepresented and rural populations.28 17 23 Micron Breaks Ground on Leading-Edge Manufacturing Fab in Boise, Idaho. September 12, 2022. https://investors.micron.com/news-releases/news-release-details/micron- breaks-ground-leading-edge-manufacturing-fab-boise-idaho 24 Id. 25 Micron Boise Expansion Plans Coming into View, October 28, 2022. https://www.ktvb.com/article/news/local/growing-idaho/boise-micron-expansion-planning-zoning- new-fab-semiconductor/277-35909baa-0305-430a-8dda-9492a1a6a105 26 Id. 27 Micron Breaks Ground on Leading-Edge Manufacturing Fab in Boise, Idaho. September 12, 2022. 28 Id. York, Di 20 Micron Technology, Inc. Q WHEN MICRON’S EXPANDED MANUFACTURING OPERATIONS 1 COMMENCE, WILL IT BE APPROPRIATE FOR MICRON TO BE INCLUDED IN 2 THE COMMERCIAL CLASS? 3 A No. Micron’s consumption will increase significantly and will be used for purposes 4 that fit the current Industrial class definition. In addition, it is my understanding that 5 Micron takes service directly from VWID’s transmission mains, and therefore it 6 should not be paying for the costs associated with small distribution mains through 7 its rates. 8 It is clear that at least one of VWID’s largest customers will qualify as an 9 Industrial customer in the next couple of years. If the utility cannot or will not 10 negotiate a special contract, or offer an economic development rate as discussed 11 below, then at the very least, I recommend that the Commission direct VWID to 12 identify a separate class in its next COSS, such as the Industrial class, for large 13 water users connected directly to the transmission system and establish a 14 separate rate that recovers that class’s cost of service. 15 IV.C. Potential Special Contract 16 Q WOULD IT BE REASONABLE FOR MICRON TO BE ELIGIBLE FOR A 17 SPECIAL CONTRACT OR ECONOMIC DEVELOPMENT RATE WITH VWID? 18 A Yes. Micron is already one of VWID’s largest customers in terms of annual water 19 consumption, and its water usage is expected to grow.29 As explained above, 20 given Micron’s significant investment in Boise and the associated benefits to the 21 state and local community, it would be reasonable for VWID to provide service to 22 Micron’s facilities under a special contract or economic development rate that more 23 29 VWID’s Response to Micron’s Discovery Request No. 44, attached as Exhibit No. 419, p. 38. York, Di 21 Micron Technology, Inc. accurately reflects VWID’s cost of providing service to Micron. In addition, Micron’s 1 expansion plan includes groundwater as a source of supply, as well as the 2 development of its own water treatment facility. A special contract or economic 3 development rate that more accurately reflects VWID’s cost of providing service to 4 Micron could improve the competitiveness of VWID’s rates relative to the cost of 5 Micron’s own water treatment process. 6 Q DOES VWID’S CURRENT TARIFF PROVIDE FOR THE ESTABLISHMENT OF 7 A SPECIAL CONTRACT, OR AN ECONOMIC DEVELOPMENT RATE? 8 A It does not appear that VWID’s current tariff identifies either of these approaches 9 as an option for new customers or existing customers with increasing consumption. 10 Q WHAT IS YOUR RECOMMENDATION WITH RESPECT TO A SPECIAL 11 CONTRACT OR ECONOMIC DEVELOPMENT RATE? 12 A I recommend that the Commission direct VWID to analyze the potential for offering 13 special contracts, or an economic development rate to certain customers, and 14 present its analysis and recommendations in the next rate case. 15 IV.D. DSIC 16 Q PLEASE DISCUSS THE COMPANY’S PROPOSAL WITH RESPECT TO THE 17 DSIC MECHANISM. 18 A The Company proposes to establish a DSIC mechanism related to the 19 replacement and/or rehabilitation of distribution system transmission and 20 York, Di 22 Micron Technology, Inc. distribution mains, services, hydrants, valves, meters, and other infrastructure.30 1 This mechanism would allow the utility to increase rates between general rate case 2 proceedings, which specifically relate to non-revenue producing investments to 3 replace aging utility infrastructure.31 4 Q DO YOU HAVE ANY CONCERNS WITH THE COMPANY’S PROPOSAL TO 5 IMPLEMENT A DSIC? 6 A Yes. First, this request is an example of single issue ratemaking, as it proposes 7 to focus on a single component of the utility’s cost of providing service and address 8 it separately from a general rate case. The Commission has previously rejected 9 single-issue, or piecemeal, ratemaking as it considers a single cost item without 10 considering other potentially offsetting revenues, and can lead to an improper 11 matching of costs and revenues and potentially unjust and unreasonable rates.32 12 Second, the Company’s proposed method of calculating the DSIC 13 incremental revenue requirement ignores offsetting reductions in the value of plant 14 investment included in base rates. 15 In light of these concerns, the Commission should reject the DSIC. 16 30 Direct Testimony of James Cagle at 3. Note that the page numbering may be mislabeled, and the correct page number may be 2 (i.e., the second page of questions and answers in the testimony). 31 Id. at 4. 32 See Intermountain Gas Company Case No. INT-G-17-07, Order No. 34090 at 6-7, where the Commission rejected Intermountain Gas Company’s proposed Infrastructure Integrity Management Mechanism. York, Di 23 Micron Technology, Inc. Q IN THE EVENT THE COMMISSION APPROVES THE COMPANY’S DSIC 1 PROPOSAL, DO YOU HAVE ANY SUGGESTED CHANGES? 2 A Yes. The Company’s capital investment costs from the replacement of DSIC 3 eligible investments should be synchronized with the investment costs included in 4 base rates. Currently, base rates include the return “of” and “on” investments 5 related to distribution system transmission and distribution mains, services, 6 hydrants, valves, meters, and other infrastructure. 7 Specifically, the Commission should ensure that VWID’s investment 8 included in base rates is synchronized with the incremental eligible investment that 9 would be subject to the DSIC. Synchronizing a utility’s total investments is fair to 10 both the utility and its customers and will ensure that a utility does not recover 11 excessive charges from its customers. 12 Q WHAT IS YOUR SPECIFIC RECOMMENDATION? 13 A The level of depreciation expense included in base rates associated with the same 14 type of infrastructure that is proposed to be eligible for the DSIC should be used to 15 offset the DSIC eligible investment prior to the rate of return calculation for the 16 DSIC surcharge. This will ensure that the utility properly recovers the incremental 17 revenue requirement associated with eligible infrastructure replacement and that 18 the utility is not allowed to charge excessive surcharges through the DSIC. 19 Once rates are set in a rate case, the utility recovers depreciation expense 20 in post-test year periods, which increases accumulated depreciation and reduces 21 net-plant balances, ultimately reducing test year rate base in the post-test year 22 periods. Post-test year plant investments offset this decline in rate base because 23 plant added to rate base offsets the increase in accumulated depreciation. If rate 24 base investments are recovered in base rates, the utility can time rate cases to 25 York, Di 24 Micron Technology, Inc. adjust rates only if a rate adjustment is justified. However, recovering post-test 1 year plant additions in a separate rate mechanism, like the DSIC, has the real 2 potential to harm ratepayers, via excess charges, for total net-plant investments 3 being used to provide service. 4 The proposed DSIC surcharge does not appear as though it would reflect 5 the decline in rate base that has occurred since base rates were last set. Thus, in 6 the years between rate cases, customers would be charged both depreciation 7 expense for plant already depreciated and new depreciation expense for new 8 investments through the incremental DSIC charge. As such, the DSIC charge as 9 proposed by VWID would result in excessive charges to customers and would 10 harm customers. It is a fundamental tenant of cost of service ratemaking that if 11 new investments cause rate base to grow at the level of depreciation, all other 12 things held constant, it is unnecessary to change customer rates for the utility to 13 fully recover the costs of the new investments. 14 My proposal will synchronize the net-plant balance for transmission and 15 distribution mains, services, hydrants, valves, meters, and other infrastructure that 16 would not be subject to DSIC replacement with the increased net plant investment 17 levels associated with the DSIC eligible investment. In this way, total charges to 18 customers, including base tariff rates and the DSIC, will track net-plant investment 19 being used to provide service during post-test year periods. 20 Q WHY SHOULD DEPRECIATION EXPENSE IN BASE RATES BE REQUIRED AS 21 AN OFFSET TO RATE BASE WHEN DETERMINING THE APPROPRIATE 22 LEVEL OF SURCHARGE REVENUE? 23 A Depreciation expense that is included in a utility’s base rates increases the utility’s 24 internal cash flow, which is used as a funding source for new plant investments 25 York, Di 25 Micron Technology, Inc. including the plant investments necessary to replace a utility’s aging or obsolete 1 infrastructure. In terms of rate base, recovering this depreciation expense in a 2 utility’s existing base rates reduces test year rate base via increases to 3 accumulated depreciation, and is used as an internal cash source to fund new 4 infrastructure capital investments that are included in post-test year utility rate 5 base. 6 This can be illustrated with an example. Assume that a certain utility has 7 annual rate case proceedings and has $10 million in annual depreciation expense 8 and $10 million in annual new capital investment. If post-test year capital 9 investment is at the same amount as post-test year depreciation expense 10 recovery, the utility’s net-plant and rate base will not grow in the post-test year 11 period. In which case, the base tariff rate revenue recovered by the utility will 12 provide it sufficient revenue to fully recover its cost of service in the post-test year 13 period. A separate charge, like the DSIC, above the base tariff rates for the 14 incremental plant investments in this example would result in excessive rates that 15 are not just and reasonable, and customers would be harmed. 16 Now assume the utility implements a rider surcharge, without recognizing 17 the declining value to existing rate base (depreciation offsets), instead of annual 18 base rate proceedings. In the case of the utility recovering the incremental 19 revenue requirement for new investment through a rider surcharge, customer rates 20 would go up to account for the $10 million spent by the utility on eligible 21 infrastructure, but the surcharge would not reflect the reduction for the $10 million 22 of depreciated rate base. Customers would pay higher bills, via the combination 23 of existing base tariff rates and the incremental DSIC, despite the utility’s net-plant 24 investment amount remaining the same. 25 York, Di 26 Micron Technology, Inc. Q PLEASE SUMMARIZE YOUR RECOMMENDATION WITH RESPECT TO THE 1 DSIC. 2 A The DSIC mechanism, as proposed by the Company, should be rejected. If the 3 Commission adopts the DSIC, I recommend modifying the DSIC revenue 4 requirement calculation to reflect depreciation expense for similar plant included in 5 base rates as an offset to the incremental DSIC plant investment for the purpose 6 of calculating a return on DSIC investment. 7 Q DOES THIS CONCLUDE YOUR DIRECT TESTIMONY? 8 A Yes, it does. 9 Appendix A York, Di 27 Micron Technology, Inc.

CASE VEO-W-22-02 FIFTH PRODUCTION REQUEST OF THE COMMISSION STAFF Preparer/Sponsoring Witness: Bui REQUEST NO. 154: The Load Study, page 7, states a key objective is to "establish a basis for selecting maximum day and maximum hour ratios for each appropriate customer classification and the total system." Please provide the specific information in the Load Study and the analysis that was performed to justify that the Company's currently defined customers are the appropriate customer classifications. RESPONSE NO. 154: The Company currently has established customer classes of Residential, Commercial, and Industrial, Public Authority, and Fire Protection. Such a classification system is consistent with typical water utility practice and norms and as suggested by AWWA Manual M1 Principles of Water Rates, Fees, and Charges. Based on the existing definition of industrial customers per the Company’s rate schedule, it is understood that no customers currently meet this definition. The scope of the Load Study examined the available data for customers in the Company’s billing system. Obtaining additional information on customer characteristics (e.g., the size of a residential lot) was beyond the scope of the study. Thus, the analysis conducted was limited to readily available customer billing information. VWID’s current classification of customers is appropriate and reflects industry norms. It represents a suitable balance between a fair segmentation of customers based on broad similarities in customer characteristics and administratively complex additional data capture and maintenance requirements.
