NOTICE OF INSIGNIFICANT PROJECT CHANGE
(Modify Water/Wastewater Treatment System)
TRACY PEAKER PROJECT
(01-AFC-16C)

The Tracy Peaker Project is a nominal 168 megawatt natural gas-fired power plant currently under construction. The facility is located in an unincorporated portion of San Joaquin County, southwest of the City of Tracy.

On March 4, 2003, California Energy Commission (Energy Commission) staff received a petition from GWF Power, to amend the Energy Commission Decision for their project.

DESCRIPTION OF PROPOSED MODIFICATIONS

GWF Power is seeking approval to substitute the permanent water/wastewater treatment system with portable treatment systems as follows:

• A portable skid-mounted system would be used during the winter months when operation is less frequent. The ion exchange resin units on the skid would be replaced no more than once per month.


• A portable trailer-mounted system would be used during peak operation (May through October) which would allow about two months of operation before the ion exchange resin would need to be replaced.

The proposed modifications would eliminate the wastewater recovery system, eliminate or make minor changes to certain storage tanks, and reduce wastewater flow from the facility. Because less-frequent deliveries would be required by the use of portable units, the modification would also reduce traffic flows.

Pursuant to section 1769(a)(2), Title 20, California Code of Regulations, Energy Commission approval for the change is not required if Energy Commission staff determines: 1) That there is no possibility that the modification may have a significant effect on the environment, and 2) That the modification will not result in a change or deletion of a condition of certification, or make changes that would cause the project not to comply with applicable laws, ordinances, regulations, or standards. Energy Commission staff have determined that the proposed modifications to the water/wastewater treatment system meets these criteria because:

• Existing conditions of certification are sufficient to cover the proposed change without changes to or deletion of a condition of certification;


• The modification will not have any significant effect on the environment because it will reduce traffic and will decrease water use; and


• The modification of the water/wastewater treatment system will allow the project to remain in compliance with applicable laws, ordinances, regulations or standards.

Any person may file a written objection to staff's determination within 14 days of service of this notice on grounds that the change does not meet the criteria set forth in Section 1769(a)(2). If you have questions about this notice, please contact Connie Bruins, Compliance Project Manager, at the address above, or call (916) 654-4545, Fax (916) 654-3882, or e-mail cbruins@energy.state.ca.us. If no substantive objection is filed and received in writing by U.S. mail, other document delivery service, or Fax within 14 days of the service of this notice to the address or Fax number shown above, the requested change will be deemed approved, and a description of the change will be placed in the project file.
