The vault toilet will replace a former vault toilet at the site that has been removed. The vault toilet was formerly known as the Knott Creek Vault Toilet. It has been renamed the “Gridley Lake Vault Toilet” to avoid confusion with other locations and assets in the area. Attachments to this contract package using the name “Knott Creek Vault Toilet” may be considered the same site as “Gridley Lake Vault Toilet.”

When construction has taken place, applicants must seek coverage under the corresponding General Permanent Holding Tank permit by completing the corresponding Notice of Intent (NOI) form.

Application instructions, materials and forms are available through NDEP at:

https://ndep.nv.gov/water/water-pollution-control/permitting/holding-tank-program.
