Notice of Construction (NOC) - Required prior to the construction, installation, replacement or modification of air contaminant sources, emissions units or air pollution control equipment in Spokane County.

Notice of Intent (NOI) - Must be obtained prior to operating a portable source installed at a specific site temporarily, not to exceed 12 consecutive months. The first time a portable source is installed and operated, a NOC is required.
