9VAC5-40-6730. Compliance.

A. The provisions governing compliance shall be as follows:

1. With regard to the emissions standards in 9VAC5-40-6670 A, 9VAC5-40-6680, and 9VAC5-40-6690, the provisions of 9VAC5-40-20 (Compliance) apply.

2. With regard to the emission limits in 9VAC5-40-6570 through 9VAC5-40-6660 and 9VAC5-40-6670 B, the following provisions apply:

a. 9VAC5-40-20 B, C, D, and E;

b. 40 CFR 60.11; and

c. Subsections B through F of this section.

B. After the date the initial emission test and continuous emission monitoring system evaluation are required or completed, whichever is earlier, the owner shall meet the applicable emission limits specified in 9VAC5-40-6570 through 9VAC5-40-6660.

C. Initial and annual emission tests shall be conducted to measure the emission levels of dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash. The results of emission tests for dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, and fugitive ash shall be used to demonstrate compliance with the applicable emission limits. Compliance for carbon monoxide, nitrogen oxides, and sulfur dioxide shall be demonstrated as provided in subsection E of this section.

D. The owner shall (i) install continuous emission monitoring systems for certain gaseous pollutants, (ii) operate continuous emission monitoring systems correctly, (iii) obtain the minimum amount of monitoring data, and (iv) install a continuous opacity monitoring system.

E. The owner shall use data from the continuous emission monitoring systems for sulfur dioxide, nitrogen oxides, and carbon monoxide in order to demonstrate continuous compliance with the applicable emission limits specified in 9VAC5-40-6610, 9VAC5-40-6620, and 9VAC5-40-6580.

F. Municipal waste combustion unit capacity shall be determined as follows.

1. For a municipal waste combustion unit that can operate continuously for 24-hour periods, the municipal waste combustion unit capacity shall be calculated based on 24 hours of operation at the maximum charge rate. The maximum charge rate shall be determined by one of the following methods.

a. For municipal waste combustion units with a design based on heat input capacity, the maximum charging rate shall be calculated based on the maximum heat input capacity and one of the following heating values:

(1) If the municipal waste combustion unit combusts refuse-derived fuel, a heating value of 12,800 kilojoules per kilogram (5,500 British thermal units per pound) shall be used; or

(2) If the municipal waste combustion unit combusts municipal solid waste, a heating value of 10,500 kilojoules per kilogram (4,500 British thermal units per pound) shall be used.

b. For municipal waste combustion units with a design not based on heat input capacity, the maximum designed charging rate shall be used.

2. Batch municipal waste combustion unit capacity shall be determined by calculating the maximum design amount of municipal solid waste that can be charged per batch multiplied by the maximum number of batches that can be processed in 24 hours. The maximum number of batches shall be calculated by dividing 24 by the number of hours needed to process one batch. Fractional batches shall be retained in the calculation; for example, if one batch requires 16 hours, the municipal waste combustion unit can combust 24/16, or 1.5 batches, in 24 hours.
