Except as otherwise provided in these Rules, and except where the context otherwise indicates, words used in these Rules are used in exactly the same sense as the same words are used in the Health and Safety Code of the State of California.

Air Contaminant or Pollutant.
Any discharge, release, or other propagation into the atmosphere directly, or indirectly, caused by man and includes, but is not limited to, smoke, dust, charred paper, soot, grime, carbon, noxious acids, fumes, gases, odors, or particulate matter, or any combination thereof.

Air Pollution Control Officer
The Air Pollution Control Officer of the Air Pollution Control District of El Dorado County.

Allowable Emissions
The emission rate calculated using the maximum design capacity of the source unless the source is subject to Permit to Operate conditions which limit the operating rate or hours of operation, or both, which is the most stringent of applicable emission limitations contained in these Rules and Regulations or the emission rate, if any, specified as a Permit to Operate condition.

Any addition to, enlargement of, replacement of, or any major modification or change of the design, capacity, process, or arrangement, or any increase in the connected loading of equipment or control apparatus, which will significantly increase or effect the kind or amount of air contaminants emitted.

Architectural Coatings
For the purpose of this rule, an architectural coating is defined as any coating applied to stationary structures and their appurtenances, mobile homes, pavements, or curbs.

  2. the date an application for Authority to Construct is deemed complete by the Air Pollution Control Officer for nonattainment pollutants.
Best Available Control Technology
An emission limitation, based on the maximum degree of reduction for a criteria pollutant or precursor which would be emitted from any source or modification which the Air Pollution Control Officer, on a case-by-case basis, taking into account energy, environmental and economic impacts, and other costs, determines is achievable for such source or modification through application of production processes or available control methods, systems and techniques, for such Pollutant. In no case shall application of best available control technology result in emissions of any pollutant of precursor which would exceed the emissions allowed by 40 CFR Part 60 and 61.

If the Air Pollution Control Officer determines that technological or economic limitations on the application of measurement technology to a particular class of sources would make the imposition of an emission standard infeasible, he may instead prescribe a design equipment, work practice or operations standard, or combination thereof. Such standard shall, to the degree possible, set forth the emission reduction achievable by implementation of such design, equipment, work practice or operation and shall provide for compliance by means which achieve equivalent results.
