Victoria L, Holink i, CPA December 4, 2012 To the Board of Commissioners Golden Valley — Crystal —New Hope Joint Water Commission 7800 Golden Valley Road Golden Valley, MN 55427 Dear Board of Commissioners: We are pleased to confirm our understanding of the services we are to provide for the Golden Valley — Crystal — New Hope Joint Water Commission (the Commission) for the year ended December 31, 2012. We will audit the financial statements of the governmental activities, each major fund, and the aggregate remaining fund information, which collectively comprise the Commission's basic financial statements as of and for the year ended December 31, 2012. Accounting standards generally accepted in the United States of America provide for certain required supplementary information (RSI), such as Management's Discussion and Analysis (MD&A), to supplement the Commission's basic financial statements. Such information, although not a part of the basic financial statements, is required by the Governmental Accounting Standards Board (GASB) who considers it to be an essential part of financial reporting for placing the basic financial statements in an appropriate operational, economic, or historical context. As part of our engagement, we will apply certain limited procedures to the Commission's RSI in accordance with auditing standards generally accepted in the United States of America. These limited procedures will consist of inquiries of management regarding the methods of preparing the infonnation and comparing the information for consistency with management's responses to our inquiries, the basic financial statements, and other knowledge we obtained during our audit of the basic financial statements. We will not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance. The MD&A is required by accounting principles generally accepted in the United States of America and will be subjected to certain limited procedures, but will not be audited. We will perform the required State Legal Compliance Audit conducted in accordance with auditing standards generally accepted in the United States of America and the provisions of the Legal Compliance Audit Guide, promulgated by the State Auditor pursuant to Minnesota Statute § 6.65, and it will include such tests of the accounting records and other procedures we consider necessary to enable us to conclude that, for the items tested, the Commission has complied with the material terms and conditions of applicable legal provisions. Our services will not include an audit in accordance with the Single Audit Act Amendments of 1996 and the U.S. Office of Management and Budget Circular A-133, which would only be required if the Commission expended $500,000 or more in federal assistance funds during the year. If the Commission is required to have a Single Audit of federal assistance funds, this engagement letter would need to be modified. Malloy, Montague, Karnowski, Radosevich & Co., P.A. 5353 Wayzata BouLrard • Suite 4io • ,Minneapolis, MN 55116 1 Telghon,: 952-50.0424 - Telefax:; 952-545-D969 - wwr,mmkr.com Golden Valley -- Crystal — New Hope Joint Water Commission page 2 December 4, 2012 Audit Objectives The objective of our audit is the expression of opinions as to whether your basic financial statements are fairly presented, in all material respects, in conformity with accounting principles generally accepted in the United States of America and to report on the fairness of the supplementary information referred to in the second paragraph when considered in relation to the financial statements taken as a whole. Our audit will be conducted in accordance with auditing standards generally accepted in the United States of America and the standards for financial audits contained in Government Auditing Standards, issued by the Comptroller General of the United States, and will include tests of the accounting records of the Commission and other procedures we consider necessary to enable us to express such opinions, If our opinions on the financial statements are other than unqualified, we will fully discuss the reasons with you in advance. If, for any reason, we are unable to complete the audit or are unable to form or have not formed opinions, we may decline to express opinions or to issue a report as a result of this engagement. We will also provide a report (that does not include an opinion) on internal control related to the financial statements and compliance with laws, regulations, and the provisions of contracts or grant agreements, noncompliance with which could have a material effect on the financial statements as required by Government Auditing Standards. The report on internal control and compliance will include a statement that the report is intended solely for the information and use of management, the body or individuals charged with governance, others within the Commission, and specific legislative or regulatory bodies and is not intended to be, and should not be, used by anyone other than these specified parties. If during our audit we become aware that the Commission is subject to an audit requirement that is not encompassed in the terms of this engagement, we will communicate to management and those charged with governance that an audit in accordance with auditing standards generally accepted in the United States of America and the standards for financial audits contained in Government Auditing Standards may not satisfy the relevant legal, regulatory, or contractual requirements. Management Responsibilities Management is responsible for the basic financial statements and all accompanying information as well as all representations contained therein. As part of the audit, we will assist with preparation of your financial statements and related notes. You are responsible for making all management decisions and performing all management functions relating to the financial statements and related notes and for accepting full responsibility for such decisions. You will be required to acknowledge in the management representation letter our assistance with preparation of the financial statements and that you have reviewed and approved the financial statements and related notes prior to their issuance and have accepted responsibility for them. Further, you are required to designate an individual with suitable skill, knowledge, or experience to oversee any nonaudit services we provide and for evaluating the adequacy and results of those services and accepting responsibility for them. Management is responsible for establishing and maintaining effective internal controls, including monitoring ongoing activities, to help ensure that appropriate goals and objectives are met. You are also responsible for the selection and application of accounting principles; and for the fair presentation in the financial statements of the respective financial position of the governmental activities, the business -type activities, die aggregate discretely presented component units, each major fund, and the aggregate remaining fund information of the Commission and the respective changes in financial position and cash flows, where applicable, in conformity with accounting principles generally accepted in the United States of America. Golden Valley — Crystal — New Hope ,loint Water Commission Page 3 December 4, 2012 Management is also responsible for making all financial records and related information available to us and for ensuring that management and financial information is reliable and properly recorded. You are also responsible for providing us with (1) access to all information of which you are aware that is relevant to the preparation and fair presentation of the financial statements, (2) additional information that we may request for the purpose of the audit, and (3) unrestricted access to persons within the Commission from whom we determine it necessary to obtain audit evidence. Your responsibilities include adjusting the financial statements to correct material misstatements and for confirming to us in the representation letter that the effects of any uncorrected misstatements aggregated by us during the current engagement and pertaining to the latest period presented are immaterial, both individually and in the aggregate, to the financial statements taken as a whole. You are responsible for the design and implementation of programs and controls to prevent and detect fraud, and for informing us about all known or suspected fraud affecting the Commission involving (1) management, (2) employees who have significant roles in internal control, and (3) others where the fraud or illegal acts could have a material effect on the financial statements. Your responsibilities include informing us of your knowledge of any allegations of fraud or suspected fraud affecting the Commission received in communications from employees, former employees, grantors, regulators, or others. In addition, you are responsible for identifying and ensuring that the Commission complies with applicable laws, regulations, contracts, agreements, and grants for taking timely and appropriate steps to remedy any fraud, illegal acts, violations of contracts or grant agreements, or abuse that we may report. You are responsible for the preparation of the supplementary information in conformity with accounting principles generally accepted in the United States of America. You agree to include our report on the supplementary information in any document that contains and indicates that we have reported on the supplementary information. You also agree to present the supplementary information with the audited financial statements OR make the audited financial statements readily available to users of the supplementary information no later than the date the supplementary information is issued with our report thereon. Management is responsible for establishing and maintaining a process for tracking the status of audit findings and recommendations. Management is also responsible for identifying for us previous financial audits, attestation engagements, performance audits or other studies related to the objectives discussed in the Audit Objectives section of this letter. This responsibility includes relaying to us corrective actions taken to address significant findings and recommendations resulting fi-om those audits, attestation engagements, performance audits, or other studies. You are also responsible for providing management's views on our current findings, conclusions, and recommendations, as well as your planned corrective actions, for the report, and for the timing and format for providing that information. Audit Procedures— General An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements; therefore, our audit will involve judgment about the number of transactions to be examined and the areas to be tested. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements. We will plan and perform the audit to obtain reasonable rather than absolute assurance about whether the financial statements are free of material misstatement, whether from (1) errors, (2) fraudulent financial reporting, (3) misappropriation of assets, or (4) violations of laws or governmental regulations that are attributable to the Commission or to acts by management or employees acting on behalf of the Commission. Because the determination of abuse is subjective, Government Audi ing Nandardy do not expect auditors to provide reasonable assurance of detecting abuse. Golden Valley — Crystal — New Hope Joint Water Commission Page 4 December 4, 2012 Because of the inherent limitations of an audit, combined with the inherent limitations of internal control, and because we will not perform a detailed examination of all transactions, there is a risk that material misstatements may exist acid not be detected by us, even though the audit is properly planned and performed in accordance with auditing standards generally accepted in the United States of America and GovernmerrtAudilingStartdards. In addition, an audit is not designed to detect immaterial misstatements or violations of laws or governmental regulations that do not have a direct and material effect on the financial statements. However, we will inform the appropriate level of management of any material errors and any fraudulent financial reporting or misappropriation of assets that come to our attention. We will also inform the appropriate level of management of any violations of laws or governmental regulations that come to our attention, unless clearly inconsequential. Our responsibility as auditors is limited to the period covered by our audit and does not extend to any later periods for which we are not engaged as auditors. Our procedures will include tests of documentary evidence supporting the transactions recorded in the accounts, and may include tests of the physical existence of inventories, and direct confirmation of receivables and certain other assets and liabilities by correspondence with selected individuals, funding sources, creditors, and financial institutions. We will request written representations from your attonieys as part of the engagement, and they may bill you for responding to this inquiry. At the conclusion of our audit, we will require certain written representations from you about the financial statements and related matters. Audit Procedures — Internal Controls Our audit will include obtaining an understanding of the Commission and its environment, including arterial control, sufficient to assess the risks of material misstatement of the financial statements and to design the nature, timing, and extent of further audit procedures. Tests of controls may be performed to test the effectiveness of certain controls that we consider relevant to preventing and detecting errors slid fraud that are material to the financial statements and to preventing and detecting misstatements resulting from illegal acts and other noncompliance matters that have a direct and material effect on the financial statements. Our tests, if performed, will be less in scope than would be necessary to render an opinion on internal control and, accordingly, no opinion will be expressed in our report on internal control issued pursuant to Government Auditing Standards. An audit is not designed to provide assurance on internal control or to identify significant deficiencies. However, during the audit, we will communicate to management and those charged with governance internal control related matters that are required to be communicated under AICPA professional standards and Government Auditing Standards. Audit Procedures — Compliance As part of obtaining reasonable assurance about whether the financial statements are free of material misstatement, we will perform tests of the Commission's compliance with the provisions of applicable laws, regulations, contracts, agreements, and grants. However, the objective of our audit will not be to provide an opinion on overall compliance and we will not express such an opinion in our report on compliance issued pursuant to Government Auditing Standards. Audit Administration, Fees, and Other We understand that your employees will prepare all cash or other confirmations we request and will locate any documents selected by us for testing. Golden Valley — Crystal — New Hope Joint Water Commission Page 5 December 4, 2012 The assistance to be supplied by your personnel, including the preparation of schedules and analysis of accounts, typing all cash or other confirmations we request, and locating any invoices selected by us for testing, will be discussed and coordinated with you.

The Joint Water Commission (1WC) is in the process of evaluating an emergency drinking water supply system comprised of a series of Prairie du Chein-Jordan aquifer wells. The system would be used if there were a long term Interruption of supply from Minneapolis. As part of the planning process, Barr Engineering assisted the JWC with the evaluation of the potential for undesirable chemical reactions to occur upon blending Prairie du Chein-Jordan groundwater with the normal softened surface water supply from the City of Minneapolis. Chemical equilibrium modeling and bench tests were conducted to evaluate the potential for formation of precipitates and corrosion of copper service piping. Results were compared to an AWWARF blending study completed by the City of Bloomington. Chemical equilibrium modeling using background water quality data for the Prarie du Chein aquifer and treated Minneapolis water quality suggested that iron precipitation may occur, but will likely be controllable via application of a sequestering agent, depending on the actual concentration of iron in the well water. Computer water quality modeling was followed up with bench testing that indicated some blends of groundwater/surface water may exceed secondary drinking water criteria for iron (0.3 mg/i. iron), and that most water blends will be near saturation with respect to calcium carbonate. Calcium carbonate precipitation may be possible for blends containing at least 25-503 well water depending on the well location and the degree of pH change occurring during distribution. Recommendations Included application of a blended phosphate to the well water for iron sequestration/inhibition of copper corrosion and monitoring of system pH during emergency water use. The results of this study can provide useful information to consumers who notice a change in the aesthetic quality of their drinking water during emergency supply conditions.
