1105 Particulate Emissions From Industrial Process Operations

Regulation No. 5 1105 Particulate Emissions From Industrial Process Operations

02/01/1981

Section 1 –

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 Regulation No. 4 7 DE Admin. Code 1104.

1.3 For all tables in this Rregulation, unless otherwise indicated, the emission limitation for a process weight rate between any two 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.

1.7 The provisions of this Regulation shall not apply to the start-up and shutdown of equipment which operates continuously or in an extended steady state when emissions from such equipment during start-up and shutdown are governed by an operation permit issued pursuant to the provisions of Section 2, Regulation No. 2 2.0 of 7 DE Admin. Code 1102.

7.0 Control of Potentially Hazardous Particulate Matter

7.1 Persons responsible for a source operation from which potentially hazardous particulate matter may be emitted such as, but not limited to, lead, arsenic, beryllium, silica, asbestos, and other such materials shall list such contaminants and their exit concentrations in a written report to the Department. The Department shall assign emission limits on an individual basis.
