Particulate Emissions from Industrial Process Operations

1100 Division of Air Quality 1105 Particulate Emissions from Industrial Process Operations 1.0 General Provisions 1.1 The emission of particulate matter from industrial process equipment shall be controlled to a limit that shall meet the ambient air quality requirements. 1.2 The provisions of this regulation shall not apply to indirect heat exchangers which shall be controlled by 7 DE Admin. Code 1104 . 1.3 For all tables in this regulation, unless otherwise indicated, the emission limitation for a process weight rate between any 2 consecutive process weight rates shall be determined by linear interpolation. 1.4 For all tables in this regulation, unless otherwise indicated, the emission limitation for process weight rate above the maximum process weight rate or below the minimum process weight rate shall be determined by linear extrapolation. 1.5 For purposes of this regulation, the allowable mass emission rate of particulate matter shall be determined for individual units of equipment. 1.6 For operations involving similar units which are manifolded to a common stack, control techniques shall be such that no unit is emitting particulate matter at a rate which is in excess of the mass emission rate allowed by this regulation. 20 DE Reg. 556 (01/01/17) 28 DE Reg. 585 (02/01/25) 2.0 General Restrictions No person shall cause or allow particulate emissions into the atmosphere from any source not provided for in subsequent sections of this regulation in excess of 0.2 grains per standard cubic foot. 20 DE Reg. 556 (01/01/17) 28 DE Reg. 585 (02/01/25) 3.0 Restrictions on Hot Mix Asphalt Batching Operations 3.1 No person shall cause or allow particulate emissions from a hot mix asphalt batching plant into the atmosphere in excess of the quantity as listed in Table 3-1 of this regulation.

For the purpose of interpolation and extrapolation calculations, "Coke Burn-Off Rate" shall be construed to be equivalent to "Process Weight Rate."

The Department shall assign emission limits on an individual basis. 12 DE Reg. 347 (09/01/08) 20 DE Reg. 556 (01/01/17) 28 DE Reg. 585 (02/01/25)
