An application fee of $1,000 is required with any permit to construct (PTC) application submitted to DEQ. DEQ will not begin processing the application until the application fee is received.
PTC Processing Fee
A PTC processing fee is assessed for each PTC that is issued, based on any increase in air pollution emissions resulting from the permitted project. DEQ calculates and assesses PTC processing fees according to the schedule (fugitive emissions are excluded).
|Permit to Construct||Fee|
|Emissions <1 ton per year||$1,000|
|Emissions = 1-10 tons per year||$2,500|
|Emmissions = 10-100 tons per year||$5,000|
|Emissions >100 tons per year|
(exempt under IDAPA 58.01.01.205.04)2
