The Idaho Department of Environmental Quality (DEQ) seeks comment on a draft reuse permit for Mayfield Ranch Water and Sewer District.
Mayfield Ranch Estates LLC. is planning a new development approximately 10 miles northwest of Mountain Home, Idaho. The development is seeking a reuse permit for a planned treatment plant and reuse system, designed for approximately 3000 homes via a central sewage system. The projected annual wastewater volume is 220 million gallons (MG) per year. Recycled water that meets Class A Recycled Water Standards will typically be sent to a 91 MG storage lagoon, which can then be used for irrigation throughout the development.
The draft reuse permit establishes monitoring requirements, limits on nutrient and hydraulic loading, and conditions established by DEQ to protect public health and the environment. As part of the permitting process, the facility was also required to show that its operation would not cause public health or environmental concerns.
Written comments on the draft permit will be accepted through July 15, at 5 p.m. Mountain Time. The draft permit and staff analysis are available for public review at DEQ’s state office (1410 N. Hilton St.), DEQ’s Boise Regional Office (1445 N Orchard St.), and below under related documents.
