Section 326IAC6-4-6. Exceptions

   The following conditions will be considered as exceptions to this rule (326 IAC 6-4) and therefore not in violation:

(1) Release of steam not in combination with any other gaseous or particulate pollutants unless the condensation from said steam creates a nuisance or hazard in the surrounding community.

(2) Fugitive dust from publicly maintained unpaved thoroughfares where no nuisance or health hazard is created by its usage or where it is demonstrated to the commissioner that no means are available to finance the necessary road improvements immediately. A reasonable long-range schedule for necessary road improvements must be submitted to support the commissioner's granting such an exception.

(3) Fugitive dust from construction or demolition where every reasonable precaution has been taken in minimizing fugitive dust emissions.

(4) Fugitive dust generated from agricultural operations providing every reasonable precaution is taken to minimize emissions and providing operations are terminated if a severe health hazard is generated because of prevailing meteorological conditions.

(5) Visible plumes from a stack or chimney which provide adequate dispersion and are in compliance with other applicable rules.

(6) Fugitive dust from a source caused by adverse meteorological conditions.
