MARIPOSA COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 102 - DEFINITIONS
Except as otherwise specifically 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.
Agricultural Operation. The growing and harvesting of crops, or raising of fowl or animals for the primary purpose of making a profit, or providing a livelihood, or the conduction of agricultural research or instruction by an educational institution.
Agricultural Waste. Are (a) unwanted or unsellable materials produced wholly from agricultural operation and (b) materials not produced from agricultural operations, but which are intimately related to the growing or harvesting of crops and which are used in the field, such as fertilizer and pesticide sacks or containers where the sacks or containers are emptied in the field. This does not include, however, such items as shop wastes, demolition materials, garbage, oil filters, tires, pallets, and the like.
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 Mariposa 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.
Alteration. 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
Approved Ignition Devices. Means those instruments or materials that will ignite open fires without the production of black smoke by the ignition device, this would include such items as liquid petroleum gas (L.P.G.), butane, propane, or diesel oil burners, flares, or other similar material as approved by the Air Pollution Control Officer. This does not include tires, tar, tar paper, oil and other similar materials.
A.R.B. The California State Air Resources Board, or any person authorized to act on its behalf.
Atmosphere. The air that envelopes or surrounds the earth. Where air pollutants are emitted into a building not designed specifically as a piece of air pollution control equipment, such emissions into the building shall be considered to be an emission into the atmosphere.
Attainment Pollutant.A criteria pollutant in an Air Pollution Control District or sub-District zone designated by the Environmental Protection Agency as an attainment area or unclassified area for such pollutant.
Baseline Concentration. The ambient concentration level reflecting actual air quality as monitored or modeled as of (1) January 1, 1981, minus any contribution from major stationary facilities and major modifications on which construction commenced on or after January S, 1975, for attainment pollutants; and (2) the date an application for Authority or 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.
Board. The Mariposa County Air Pollution Control Board.
Breakdown Condition.
