| 4 | Repairs. |
| 4.1 | In addition to the monthly and annual inspections, repairs shall be performed as needed. In the course of inspections, if a tank system is discovered to be inoperative (e.g. the automatic tank gauging system control panel is not functioning, or a leak is discovered) the Contractor will notify the COR. The Contractor will, to the best of his ability, map out the deficiency and the best course of action for correcting/repairing it. This will include an estimate of both cost and time for repair. After consultation with Environmental Division, the COR will notify the Contractor on the appropriate action to take to rectify the deficiency. |

The Government shall reimburse the Contractor for the balance of the parts cost that cumulatively exceeds $100.00. This cost shall be based on a per tank/inspection basis. |
| 4.1.3 | In the event minor repairs cannot be made at the time of discovery due to parts availability or other reasons beyond the Contractor’s control, the Contractor shall immediately notify the designated representative. The Contractor shall provide a written deficiency report within 24 hours of discovery of the deficiency. Once issues preventing the repairs have been resolved, the Contractor shall return to the deficient tank and perform needed repairs. Any deficiencies identified shall be reported utilizing the Contractor’s checklist form. |
| 4.2 | In the event a major repair is needed, the Contractor shall provide the COR with a written proposal within 24 hours or 1 normal working day after storage tank system was evaluated. The proposal shall be detailed and itemized, including start date, estimated labor hours required (lead technician and helper technician if required) and parts list including Contractor’s cost of parts and shipping cost. The Contractor’s quotes shall clearly indicate whether all parts are available for immediate purchase by the Contractor or the date of their expected availability. |

| 4.6 | The Contractor shall not perform any Repair Work that would exceed the approved quote. |
| 4.7 | Upon completion of Repair Work, the Contractor shall test and certify the fuel storage tank system. |
| 4.7.1 | The Contractor’s QC representative shall conduct a 100% inspection and acceptance test of all repair work to ensure proper operations of the work completed prior to opening the system to the public. |
