o N en -..J The three entities, CLV, CCSD, and COH have joined together to form the Clean Water CoalitioUj and in 1998, began the Alternate Discharge Study, which is an effort to find alternative methods for disposal of increasing amounts of reclaimed wastewater back to the Colorado River System to insure return flow credits for Nevada while also insuring the environmental standards are met. The study, which has a 30 year planning horizon, has resulted in a number of options including improved treatment processes, pipelines to new locations and diffusers in Lake Mead or the Colorado River, which are currently under study and environmental review. Other Activities A program has been developed by CCSD, CLV, and CNLV to coordinate investigate, and encourage the implementation of management practices resulting in reduction of wastewater salinity. The principal emphasis of this program will be directed toward salinity control to meet the requirements of the NPDES permits issued to Clark County, the City of Las Vegas, and Henderson. New Mexico NPDES Permits Authority for issuing permits has not been delegated to the state of New Mexico. Currently, the program is being administered by EP A, Region VI, except for facilities located on the Navajo . Indian Reservation, which are administered by Region IX. EP A is following Forum policy in the administration of the permit program. All new or renewed discharge permits contain language requiring the permittee to adhere to Forum policy reglU'ding salt discharges. hi the Colorado River Basin within the state, the following permits have been issued: a. Industrial permits: electric power generation (3), coal mines (6), uranium mines (3), sand and gravel operations (3), small domestic sewage treatment plants (3), small process water treatment facility (2), and a drinking water treatment plant (1). b. Municipal discharge permits: major sewage treatment plants (3) minor sewage treatment plants (2), and federa1!Indian wastewater facilities (11). Water Quality Management Planning Work elements of the State of New Mexico Water Quality Management Plan (NMWQMP) and the New Mexico Nonpoint Source Management Plan (NPSMP) applicable to the Colorado River Basin ar~ stream bottom deposits and sediment control from many different sources, including hydromodification, silviculture and irrigated agriculture. The New Mexico Water Quality Control Commission is required to approve and adopt the NMWQMP's for New Mexico. The initial Plan was adopted in two parts in Qctober 1978 and May 1979. The most recent update to the NMWQMP was adopted in 1991. The most recent update of the NPSMP was in December 1999. Both plans 4-24
