▪ A matter of bias, discrimination or conflict of interest on the part of the evaluator;

▪ Errors in computing the score or Bid Price upon which award decisions are based; or

3. The determination by Energy Northwest shall either:

a. Find the protest lacking in merit and uphold Energy Northwest’s action; or

b. Find only minor technical or harmless errors in Energy Northwest’s acquisition process and determine Energy Northwest to be in substantial compliance and therefore reject the protest; or

c. Find merit in the protest and pursue correction including correcting the errors and reevaluating the Bids, and/or reissuing the solicitation to begin a new process; or

d. Make other findings and determine other courses of action, as appropriate.

E. Stay of Award of the Contract: Energy Northwest will stay award of the Contract for two business days following the issuance of its final decision. The term “business day” shall mean any day on which Energy Northwest is open for regularly conducted business.

F. Appeal: Any appeal must be filed within two business days of the determination being delivered by the Energy Northwest General Counsel to the aggrieved party.

An appeal must be in writing and submitted to the Energy Northwest General Counsel. The written statement of appeal must provide a substantial basis for an appeal, based on the information submitted as part of the original protest. New information or basis of protest will not be considered during the appeal process.

This shall be the final appeal provided to the protestor.

RCA.

B. In limited situations, Contractor equipment that cannot be freely released from an

RCA may be evaluated for cost reimbursement by Energy Northwest.

C. The following rules apply to Work in an RCA:

1. Contractor is responsible for their own equipment, tools and material brought into the RCA for the performance of the Work.

2. Decontamination of equipment, tools, and materials is the responsibility of the

Contractor. Energy Northwest will not be responsible for the decontamination of equipment, tools, and materials that are taken into an RCA.

a. Radiation Protection (RP) and plant labor force will perform decontamination of work areas and equipment as it is removed from the RCA. This decontamination is done to maintain radiological conditions in the work area. Contractor personnel shall be required to use good radiological practices in controlling the spread of contamination in their work areas. Contractor personnel are also required to use good radiological work practices to minimize contaminating equipment that is used in an RCA.

b. Energy Northwest will not support decontamination of non-radioactive equipment that is used inside an RCA and becomes contaminated.

Energy Northwest will not provide resources to decontaminate this equipment for free release. Energy Northwest will ship this equipment as radioactive to another radioactive material licensee at the Contractor’s expense.

c. Electronic equipment and specialized equipment that is brought into the

RCA will have to be protected from becoming internally contaminated.

Energy Northwest does not guarantee that this type of equipment will be freely released at the end of the project. Energy Northwest will work with the Contractor to perform pre-use radiological surveys, protection scheme and post-work surveys.

3. Energy Northwest reserves the right to conduct radiological surveys on equipment, tools and materials that arrive onsite for radiological contamination.

Items found to be contaminated will be controlled as radioactive material.

Processing costs will be charged to the Contractor. Contactor shall be responsible for any NRC violations that are found during the surveys.

4. Energy Northwest reserves the right to prohibit tools, equipment or materials from entry into or use in the RCA based on environmental, chemical, plant and radiological issues or concerns.

5. Energy Northwest does not guarantee that equipment, tools and materials used or brought into the RCA will be free released to unrestricted areas after the completion of Work.

6. Equipment, tools or materials that contain fans may not be freely released from an RCA without a release plan. The equipment, tools or materials that are not freely released will be controlled as radioactive material and shipped back to the Contractor’s designated location as a U.S Department of Transportation (DOT) radioactive shipment. If Energy Northwest supports the shipment of any items, the cost of shipping will be charged to the Contractor.

7. Equipment, tools or materials that come into contact or utilize potentially contaminated gases or fluids will not be freely released from the RCA. These items will be controlled as radioactive material and shipped back to the Contractor’s designated location as a DOT radioactive shipment. If Energy Northwest supports the shipment of any items, the cost of shipping will be charged to the Contractor.

8. Contractor is responsible for the removal and shipment of equipment, tools or materials that are radioactive after the completion of the Work. If Energy Northwest supports the shipment of any items, the cost of shipping will be charged to the Contractor.

9. Contractor shall have an NRC license to receive radioactive materials if equipment, tools or materials are to be shipped from Energy Northwest to the Contractor’s designated facility. If Energy Northwest supports the shipment of any items, the cost of shipping will be charged to the Contractor.
