SAN LUIS OBISPO COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 403 - PARTICULATE MATTER EMISSION STANDARDS
(Adopted 8/2/76)

A. PARTICULATE MATTER

Except as otherwise provided in Rule 403.C.1 a person shall not discharge into the atmosphere from any source particulate matter in excess of 0.3 grains per cubic foot of dry gas at standard conditions.

B. DUST AND FUMES

A person shall not discharge in any one hour from any single source whatsoever dust or fumes in total quantities in excess of the amount shown in the following table.

To use the following table, take the process weight per hour as such is defined in Subsection 61 of Rule 105. Then find this figure in the table and number to the right is the maximum number of pounds of contaminants which may be discharged into the atmosphere in any one hour. As an example, if A has a process which emits contaminants into the atmosphere and which process takes 3 hours to complete, he will divide the weight of all materials in the specific process, in this example 1,500 lbs, by 3 hours giving a process weight of 500 lb/hr. The table shows that A may not discharge more than 1.77 lbs in any one hour during the process. Where the process weight per hour falls between the figures in the left hand column, the exact weight of permitted discharge may be interpolated.

C. COMBUSTION CONTAMINANTS

  1. A person shall not discharge into the atmosphere from any existing single source of emission whatsoever combustion contaminants, in any state or combination thereof, exceeding at the point of discharge 0.3 grains per cubic foot of gas calculated to 12 percent of carbon dioxide (CO2) at standard conditions. 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).
  2. A person shall not build, erect, install or expand any non-mobile fuel burning equipment unless the discharge into the atmosphere of contaminants, as defined in Rule 105, will and does not exceed 10 pounds per hour derived from the fuel.

For the purpose of this subsection, a fuel burning equipment unit shall be comprised of the minimum number of boilers, furnaces, jet engines or other fuel burning equipment, the simultaneous operation of which are required for the production of useful heat or power.

Fuel burning equipment serving primarily as air pollution control equipment by using a combustion process to destroy air contaminants shall be exempt from the provisions of this Rule.

Nothing in this Rule shall be construed as preventing the maintenance or preventing the alteration or modification of an existing fuel burning equipment unit which will reduce its mass rate of air contaminant emissions.
