After reading this message on the IFlub Board, I have to assume that certain poster's will be required to have an EPA permit to post there.

" The purpose of permits is to ensure compliance with all state and federal air pollution control rules, which are designed to protect public health and the environment.

Any business or industry (source) in Idaho that emits, or has the potential to emit, pollutants into the air is required to have an air pollution control permit from DEQ. Permits are issued when new sources begin operation and when existing sources modify their facilities."
