At the July 18, 2012, City Council meeting, representatives of Roseville Electric presented a proposal for the Roseville Energy Park Liquid Management System. The proposal is for Phase 3 of the system which would cover disposal of the wastewater generated from the power plant. As described, Phase 3 would consist of a 12-month process to obtain all the necessary permits and public outreach, to be followed by the actual 6-9 month construction period.
The Liquid Management System would replace the current costly method of disposing of the wastewater, saving well over $1 million per year. The proposed new system would consist of two injection wells which would inject the wastewater to a low permeable salt-water level below the Aquifer system. Details of the plan were presented to the Council, and can be seen as represented to the Roseville Public Utilities Committee on June 26, 2012 and a FAQ from Roseville Electric at the City’s website.
WFFNA President Sue Hallahan-Cook addressed the Council with concerns over any long range effects of injecting the wastewater into the Aquifer system and any other environmental impacts to the area. The West Roseville area will have 11 injection wells into the Aquifer System which will store drinking water when needed for the City’s residents.
Assurances were made that full CEQA studies will be done by both the Federal Environmental Protection Agency and the California Energy Commission. As part of the public outreach, the CEC will participate and meet with neighborhoods to answer questions and concerns about the Liquid Management System. Although one public meeting had already been held at Sun City, Mrs. Cook asked that all neighborhoods and residents, especially those in the West Roseville area adjacent to the power plant, be kept in the public process. WFFNA will keep you informed as we hear further.
