The county's fuel-gas amendments exempt portable heating appliances, minor component replacements that do not change an appliance's approval or make it unsafe, portable ventilation appliances, portable cooling units, steam/hot-water/chilled-water piping within regulated equipment, portable evaporative coolers, and self-contained refrigeration packages. The general permit code's exemptions remain subject to all other laws and ordinances; deck/porch/pier construction in unincorporated Boone County requires a permit.
