COLUSA COUNTY AIR POLLUTION CONTROL DISTRICT

REGULATION II - PROHIBITIONS

RULE 2.16 - DUST AND FUMES

A person shall not discharge in any one hour from any source whatsoever, except as provided by Rule 2.14, subsections a. and c. of this regulation, dust or fumes in total quantities in excess of the amounts shown in the following table;

To use the following table, take the process weight per hour as such is defined in the attached definitions. Then find this figure on the table opposite which 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 four (4) hours to complete, he will divide the weight of all materials in the specific process, in this example 2,400 lbs., by '4', giving a process weight per hour of 600 lbs. The table shows that "A" may not discharge more than 1.83 lbs., in any one hour during the process. Interpolation of the data in the table for process weights up to 60,000 pounds/hour shall be accomplished by use of the equation:

E = 4.10 P0.67

and interpolation and extrapolation of the data for process weight rates in excess of 60,000 pounds/hour shall be accomplished by use of the equation:

E = (55.0 P0.11) - 40
