Appendix 2: UIC Business Rules Requirements



UIC Business Rules Requirements (7/2/2010)

Required 1: Submission of the business object or data element is mandatory. If a required object or element is missing (blank value), in an incorrect format, or has an unacceptable value, the data submission will be rejected by the data validation software and returned to the State/Region to be revised and re-submitted.

Required 2: Submission of the business object or data element is expected, but NOT mandatory. If a ‘Required 2’ object or element is missing (blank value), in an incorrect format, or has an unacceptable value, the data submission will be accepted. However, the validation software will strip the field of its value before it is accepted and produce a message to alert the submitting state/DI program that the expected data are missing or the value is not accepted.

There are 8 Inventory tables (of 18 tables totally) in the required-1 category: Facility, Contact, Permit, Permit Activity, Well, Well Type, Well Status, and Location. The other 10 tables are required- 2 category. Data collected from these tables is used to automate all UIC reporting requirements.

Data Type: Alphanumeric – letter, number, dash, and dot; Date – valid date in specified format; Numeric – number in specified format; String – letter, number and any special characters. Use Upper Case for values populated to each data field.

| | | |populated |the same value of Well ID. Each record will have a unique date. |

| | | | |So if a well changes different operating status in the same date, |

| | | | |make sure to use a date before for the old well operating status |
