Section 920. Determination of collection equipment efficiency factor

Latest version.

The efficiency factor for the collection equipment shall be established as follows:

1. For all collection equipment, except mechanical collectors, the efficiency factor shall be 1.0.

2. For mechanical collectors, the efficiency factor shall be the quotient of the design efficiency of the collector at rated capacity and the actual efficiency of the collector at the reduced actual load. The actual efficiency shall be the product of the design efficiency and the correction factor where:

Correction Factor =

1 + log₁₀ (actual load)

1 + log₁₀ (rated capacity)

3. For collection equipment where the owner does not wish to accept the efficiency factor established by subdivision 1 or 2 of this section, the owner may provide information and data as a substitute. Such information and data may be emissions test results or other conclusive evidence. If such information and data is found acceptable by the board, it may be used to establish the efficiency factor for the collection equipment.

	Correction Factor =	1 + log₁₀ (actual load)
	Correction Factor =	1 + log₁₀ (rated capacity)
