IMPERIAL COUNTY AIR POLLUTION CONTROL DISTRICT



RULE 403. GENERAL LIMITATIONS ON THE DISCHARGE OF AIR CONTAMINANTS (Adopted11/19/85; revised 9/14/99)


A. Applicability

This Rule applies to the discharge of Air Contaminants, Combustion Contaminants, and Particulate Matter into the Atmosphere


B. Requirements

B.1 A Person shall not discharge into the Atmosphere from any single Emissions Unit, Particulate Matter, including lead and lead compounds, in excess of the rate shown in Table 403-1. For the purposes of this Rule, emissions shall be averaged over one complete cycle of operation or one hour, whichever is the lesser time period. Where the Process Weight Per Hour is between figures listed in the table, the exact weight of permitted discharge shall be determined by linear interpolation.

B.2 A Person shall not discharge into the Atmosphere from any single Emissions Unit, Air Contaminants in excess of the concentrations at Standard Conditions shown in Table 403-2. Where the volume discharged is between figures listed in the table, the exact concentration allowed to be discharged shall be determined by linear interpolation.

B.3 A Person shall not discharge into the Atmosphere from any single Emissions Unit, constructed after July 1, 1972, Combustion Contaminants exceeding in concentration at the point of discharge of 0.2 grains per dry cubic foot of gas, calculated to 12 percent of carbon dioxide (CO2) at Standard Conditions averaged over 25 consecutive minutes. In measuring the Combustion Contaminants from Incinerators used to dispose of Combustible Refuse by burning, the carbon dioxide (CO2) produced by combustion of any liquid or gaseous fuels shall be excluded from the calculation to 12 percent of carbon dioxide (CO2). Sources are exempt from the requirements specified in Section B.3 during start-up, and during changes in load when bringing the combustion process up to operating levels.

B.4 A Person shall not discharge Combustion Contaminants derived from the fuel in excess of 10 pounds per hour from a new or existing stationary Fuel Burning Equipment unit.
