(a) Maximum Emissions. Particulate matter is fine solid or liquid particles small enough to be carried in the air, including products of combustion such as soot and fly ash, industrial dust, and products of wind erosion.
The rate of emission of particulate matter from all sources within the boundaries of any lot shall not exceed the values in Table 40, subsection (b) hereof, as adjusted by the factors in Table 41, subsection (e) hereof.
(b) Table 40: Particulates Standards.
Use | Maximum Pounds Per Acre of Net Site Area Per Hour | Maximum Tonnage Per Acre of Net Site Area Per Year |
Heavy industrial | 5 | 10 |
Other | 1 | 5 |
(c) Measurement. The emission rate in pounds per hour from any single stack shall be determined by selecting the continuous four-hour period which shall result in the highest average emission rate.
(d) Control of Wind Erosion. Emission of particulate matter from materials, products or surfaces subject to wind erosion shall be minimized by paving, oiling, wetting, covering, landscaping, fencing or other means.
This shall apply to vacant lots; unpaved roads; yards and storage piles of bulk materials such as coal, sand, cinders, slag and sulfur; and similar sources of windborne particulates.
(e) Table 41: Adjustments to Particulates Standards.
