9VAC5-80-1105. Permit Exemptions.

A. The general requirements for minor NSR permit exemptions are as follows:

1. The provisions of this article do not apply to the following stationary sources or emissions units:

a. The construction of any stationary source or emissions unit that is exempt under the provisions of subsections B through F of this section. In determining whether a source is exempt from the provisions of this article, the provisions of subsections B through D of this section are independent from the provisions of subsections E and F of this section. A source must be determined to be exempt both under the provisions of subsections B through D of this section taken as a group and under the provisions of subsections E and F of this section to be exempt from this article.

b. Vegetative waste recycling/mulching operations that do not exceed 2100 hours of operation in any 12-month consecutive period at a single stationary source. To qualify as an exemption under this subdivision, the total rated capacity of all diesel engines at the source, including portable diesel engines temporarily located at the site, may not exceed 1200 brake horsepower (output).

c. The location of a portable emissions unit at a site subject to the following conditions:

(1) Any new emissions from the portable emissions unit are secondary emissions.

(2) The portable emissions unit is either subject to (i) a minor NSR permit authorizing the emissions unit as a portable emissions unit subject to this subdivision or (ii) a general permit.

(3) The emissions of the portable emissions unit at the site would be temporary.

(4) The portable emissions unit would not undergo modification or replacement that would be subject to this article.

(5) The portable emissions unit is suitable to the area in which it is to be located.

(6) Reasonable notice is given to the board prior to locating the emissions unit to the site identifying the proposed site and the probable duration of operation at the site. Such notice shall be provided to the board not less than 15 days prior to the date the emissions unit is to be located at the site unless a different notification schedule is previously approved by the board.

d. The reactivation of a stationary source unless a determination concerning shutdown has been made pursuant to the provisions of 9VAC5-20-220.

e. The use by any existing stationary source or emissions unit of an alternative fuel or raw material, if the following conditions are met:

(1) The owner demonstrates to the board that, as a result of trial burns at the owner's facility or other facilities or other sufficient data, the emissions resulting from the use of the alternative fuel or raw material supply are decreased. No demonstration will be required for the use of processed animal fat, processed fish oil, processed vegetable oil, distillate oil, or any mixture thereof in place of the same quantity of residual oil to fire industrial boilers.

(2) The use of an alternative fuel or raw material would not be subject to review under this article as a project.

2. The provisions of this article do not apply to the following stationary sources or emissions units provided the stationary source or emissions unit is (i) exempt under the provisions of subsections E and F of this section and (ii) meets any other applicable criteria or conditions set forth in this subdivision.

a. Replacement of an emissions unit subject to the following criteria:

(1) The replacement emission unit is (i) of an equal or lesser size and (ii) of an equal or lesser rated capacity as compared to the replaced emissions unit.

(2) The replacement emissions unit is functionally equivalent to the replaced emissions unit.

(3) The replacement emissions unit does not change the basic design parameters of the process operation.

(4) The potential to emit of the replacement emissions unit does not exceed the potential to emit of the replaced emissions unit. If the replaced emissions unit is subject to terms and conditions contained in a minor NSR permit, the owner may, concurrently with the notification required in subdivision (6) of this subdivision, request a minor amendment as provided in 9VAC5-80-1280 B 4 to that permit to apply those terms and conditions to the replacement emissions unit. However, the replacement emissions unit's potential to emit is not limited for the purposes of this subdivision unless (and until) the requested minor permit amendment is granted by the board.

(5) The replaced emissions unit is either removed or permanently shut down in accordance with the provisions of 9VAC5-20-220.

(6) The owner notifies the board, in writing, of the proposed replacement at least 15 days prior to commencing construction on the replacement emissions unit. Such notification shall include the size, function, and rated capacity of the existing and replacement emissions units and the registration number of the affected stationary source.

b. A reduction in stack outlet elevation provided that the stack serves only facilities that have been previously determined to be exempt from the minor NSR program.

3. In determining whether a facility is exempt from the provisions of this article under the provisions of subsection B of this section, the definitions in 9VAC5-40 (Existing Stationary Sources) that would cover the facility if it were an existing source shall be used unless deemed inappropriate by the board.

4. Any owner claiming that a facility is exempt from this article under the provisions of this section shall keep records as may be necessary to demonstrate to the satisfaction of the board that the facility was exempt at the time a minor NSR permit would have otherwise been required under this article.

B. Facilities as specified below shall be exempt from the provisions of this article.

1. Fuel burning equipment units (external combustion units, not engines and turbines) and space heaters in a single application as follows:

a. Except as provided in subdivision b of this subdivision, the exemption thresholds in subdivisions (1) through (4) of this subdivision shall be applied on an individual unit basis for each fuel type.

b. The uncontrolled emissions rate of any regulated air pollutant that would be emitted from the temporary facility during the operational period does not exceed the applicable exempt emission rate as set forth in 9VAC5-80-1105 C (exemption rates for new stationary sources) or 9VAC5-80-1105 D (exemption rates for projects).

2. If the particulate matter (PM10 or PM2.5) emissions for a stationary source can be determined in a manner acceptable to the board and the stationary source is deemed exempt using the emission rate for particulate matter (PM10 or PM2.5), the stationary source shall be considered to be exempt for particulate matter (PM). If the emissions of particulate matter (PM10 or PM2.5) cannot be determined in a manner acceptable to the board, the emission rate for particulate matter (PM) shall be used to determine the exemption status.
