J. Miscellaneous
- Brazing, soldering, or welding equipment. This exemption applies to conventional
brazing, soldering, or welding operations only; any internal combustion engine or other equipment associated with

- Source operation operated at one stationary source for not more than 45 days,
which is not a replacement for a specific application which lasts or is intended to last for more than 45 days
at one stationary source, and which emits less than two tons per year of any air contaminant. To qualify for this
exemption, a written request shall be made to the Control Officer including: identification of the source operation,
documentation emissions will not exceed two tons per year of any air contaminant, and proposed form and location
of records to be used to verify qualification for exemption. If the Control Officer does not respond to such request
within 30 days, it shall be deemed approved. To retain such exemption, the owner of a source operation shall reapply
biannually. Each request for exemption or reapplication shall be accompanied by a $104 filing fee.

and which have been documented with a written analysis by the Control Officer to:
a. emit no more than 10 pounds uncontrolled in any 24 hour period,
b. emit no more than 180 pounds in any quarter, and
c. not interfere with provisions of the newest adopted Air Quality
Attainment Plan.

Standards (NSPS), or EPA 40 CFR, Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAPS);
B. Those for which the Control Officer makes a determination
a permit shall be required because such source operation may not operate in compliance with all district rules
and regulations; or
C. Those proposed as part of soil or groundwater remediation projects.
IV. Recordkeeping
Recordkeeping shall be required to verify or maintain any exemption if such exemption
is based on a maximum daily emission limitation.
