- 1 For exceptions due to breakdowns or scheduled maintenance: see Chapter 35

– COMPLIANCE; EXCEPTIONS DUE TO STARTUP, SHUTDOWN, OR MALFUNCTION

001 No person shall cause, suffer, allow or permit the emission of particulates from

any processing machine, equipment, device or other articles, or combination thereof,

except indirect heating equipment and incinerators, in excess of the amounts allowed in

Table 20

- 2 during any one hour.

002 No person shall cause or allow particulate matter caused by the combustion of

fuel to be emitted from any stack or chimney into the outdoor atmosphere in excess of

the hourly rate set forth in Table 20

- 2 003 For the purpose of these regulations, the total heat input shall be the aggregate

heat content of all fuels whose products of combustion pass through a stack or

chimney, or the equipment manufacturer's or designer's guaranteed maximum input,

whichever is g reater. The total heat input of all fuel burning units at a plant or on a

premises shall be used for determining the maximum allowable amount of particulate

matter which may be emitted.

004 No person shall cause or allow emissions, from any source, which are of an

opacity equal to or greater than twenty percent (20%), as evaluated by an EPA

approved method, or recorded by a continuous opacity monitoring system operated and

maintained pursuant to 40 CFR Part 60 Appendix B except as provided for in section

005 of this chapter.

005 Exceptions:

005.01 No person shall cause or allow emissions from any existing teepee waste

wood burner which are of an opacity equal to or greater than forty percent (40%).

005.02 No person shall cause or allow emissions from any existing alfalfa

deh ydration plant dryer which are of an opacity equal to or greater than thirty

percent (30%).

005.03 Emission sources subject to monitoring requirements of Chapter 34, 005

of this Title are allowed to have one six minute period per hour of not more than 27

percent opacity.

005.04 Furnaces owned and operated by a law enforcement agency to dispose

of ammunition, fireworks or similar flammable or explosive materials are exempt

from the provisions of this Chapter solely while being used for this purpose.

006 All sources shall co mply with section 004 of this Chapter unless an opacity

standard applies as specified elsewhere in this Title

007 Interpolation of the data in this table for process weight rates up to 60,000 Lb/Hr

shall be accomplished by use of the equation E = 4.10 p .67 and interpolation and

extrapolation of the data for process weight rates in excess of 60,000 Lb/Hr shall be

accomplished by use of the equation E = 55.0 p .11

- 40, where E = rate of emission in

Lb/Hr and P = process weight rate in Tons /Hr. If two or more units discharge into a

single stack, the allowable emission rate will be determined by the sum of all process

weights discharging into the single stack.

008 Section 001 and Section 002 of this Chapter shall apply unless a more stringent

particulate matter standard is specified in the underlying requirements of an applicable

federal rule or is specified within a construction permit issued pursuant to this Title.
