New research facilities planned for the primate center on the University of California, Davis, campus and the extension of a main sewage line to the primate center are the subjects of two draft environmental impact reports released July 29 and Aug. 2 for public review and comment. Copies of the draft EIRs are available at the reserve desk in Shields Library and at the Yolo County Library in Davis or may be obtained from the UC Davis planning and budget office. Public hearings will be held Aug. 19 for the primate center draft EIR and Aug. 26 for the wastewater connection draft EIR, both at 7 p.m. in Room 002 of Wellman Hall on campus. Deadlines for public comment are Sept. 13 for the wastewater draft EIR and Sept. 16 for the primate center draft EIR. Plans for the California Regional Primate Research Center facilities had been discussed during an informational public meeting held last February. "The winter forum gave the university a chance to hear questions and comments from neighbors and other interested people and speak directly to them in the draft EIR," said campus planner Bob Segar. "It was helpful." The primate center draft EIR covers three new buildings designed to house research animals as well as proposals to construct a small AIDS research laboratory, a facility to house the Center for Comparative Medicine and a small quarantine building. The wastewater draft EIR covers a proposal to extend a main sewage line to the primate center to connect it with the main wastewater treatment plant on campus. The line would also be capable of handling potential campus development west of Highway 113. The primate center, located on the rural western edge of the campus at the intersection of Hutchison Drive and Road 98, is more than 30 years old. One of seven national primate centers supported by the U.S. Department of Health and Human Services, it has been the site of studies in AIDS, respiratory diseases, developmental and reproductive biology, behavioral biology, immunology and virology.
