One of the following mechanisms may be used to meet the UIC requirements: <br />1. A Surety Bond along with a Standby Trust Fund <br />2. A Letter of Credit along with a Standby Trust Fund <br />3. A Trust Fund <br />4. State Mechanisms (the permittee needs to provide a copy of the state mechanism such as a surety <br />bond, a letter of credit, a certificate of deposit or a blanket bond) along with a letter requesting <br />acceptance of the state mechanism. Whenever a state blanket bond is used as a financial mechanism <br />to cover the cost of plugging the well, the pernuttee is required to provide a list of all wells <br />(producers and injectors) covered by the blanket bond and the estimated plugging cost for each well. <br />5. Financial Statement Coverage -the following are required when financial statement coverage is used <br />as financial mechanism: chief financial officer's letter, an independent auditor's opinion of <br />examination of the company's financial statements and a public accounting firm's statement of <br />validation of the financial information in the chief financial officer's letter. <br />Enclosed is a brochure discussing financial mechanisms. (This brochure will be scanned and made <br />available in the near future.) <br />3 0(5 5!28/99 5:37 PM <br />
