616.01 Description. This work consists <strong>of</strong> applying water or dust palliative for<br />

the alleviation or prevention <strong>of</strong> dust nuisance originating from earthwork<br />

construction operations from within the project construction limits.<br />

616.02 <strong>Construction</strong> Requirements. Perform dust control operations at the<br />

time <strong>and</strong> location <strong>and</strong> in the amount ordered by the Engineer. Maintain control <strong>of</strong><br />

the application <strong>of</strong> water or dust palliative at all times to minimize dust but not to<br />

create saturated soil conditions. The Engineer will determine whether water or<br />

dust palliative is to be used to alleviate or prevent dust nuisance, <strong>and</strong> the amounts<br />

<strong>of</strong> each material to be used. Do not apply calcium chloride to areas that will be<br />

subsequently seeded or sodded.<br />

Furnish <strong>and</strong> apply water used for dust control by means <strong>of</strong> tanks equipped with<br />

suitable sprinkling devices.<br />

Use dust palliative consisting <strong>of</strong> 712.02 calcium chloride or a brine solution<br />

containing a minimum <strong>of</strong> 30 percent by weight <strong>of</strong> calcium chloride. Spread the<br />

calcium chloride uniformly over the surface.<br />

The <strong>Department</strong> will measure Calcium Chloride by the number <strong>of</strong> tons (metric<br />

tons) by weight measurement, furnished <strong>and</strong> applied. When brine is used, the<br />

<strong>Department</strong> will determine the weight <strong>of</strong> calcium chloride by multiplying the<br />

number <strong>of</strong> gallons (cubic meters) by the factor 0.0024 (0.575).<br />
