No construction permits shall be required for the sources listed in Regulation 61-62.1, Section II (B)(1)(a) through (c) (pdf) which burn virgin fuel and which were constructed prior to February 11, 1971 and which are not located at a facility that meets the definition of a major source as defined in Regulation 61-62.70.2(r) (pdf) ; however, modifications at these facilities may trigger the requirement to obtain a construction permit.
No construction permits shall be required for the sources listed in Regulation 61-62.1, Section II (B)(2)(a) through (h) (pdf) , unless otherwise specified by Regulation 61-62.70 (pdf) or any other State or Federal requirement. A source's exemption status may change upon the promulgation of new regulatory requirements applicable to any of the sources listed in Section II (B)(2)(a) through (g), or to any other sources that have been determined to have total uncontrolled emissions less than the thresholds in Section II (B)(2)(h), or to any similar sources that have been granted an exemption by the Department.
Sources with a total uncontrolled emission rate of less than 1 lb/hr each of particulates, sulfur dioxide, nitrogen oxides, and carbon monoxide; and a total uncontrolled emission rate of less than 1000 lbs/month of VOC will not require construction permits. However, these sources may be required to be included in any subsequent construction or operating permit review to ensure that there is no cause or contribution to an exceedance of any ambient air quality standard or limit. For toxic air pollutant exemptions, refer to Regulation 61-62.5 - Standard No. 8, Toxic Air Pollutants (pdf).
