Title 7 Natural Resources and Environmental Control
1100 Air Quality Management Section
1105 Particulate Emissions from Industrial Process Operations
02/01/1981
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 qualityrequirements.
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 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 commonstack, 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 2.0 of 7 DE Admin. Code 1102.
