0101-37 Soil remediation
Applies to:
Businesses engaged in various types of remediation of soil contaminated with hazardous or toxic materials, including oil spill cleanup on land.
Note: Soil remediation can take place at the site of the contamination, or the contaminated soil may be hauled to another area for remediation.
Equipment used include, but are not limited to:
* Backhoes;
* Bulldozers;
* Dump trucks;
* Frontend loaders;
* Other dirt moving equipment;
* Tillers; and
* Incinerators.
Soil remediation methods used include, but are not limited to:
* Bio-remediation: Contaminated soil is mixed with nutrients, sawdust, and various other additives. Naturally occurring bacteria in the soil break down the pollutants;
* Encapsulation: Contaminated soil is enclosed in some type of protective material to prevent drainage into surrounding soil;
* Excavation and hauling to an approved disposal site;
* Hot air vapor extraction: A burner unit is mounted on a trailer. Contaminated soil is arranged in layers on which an aluminum perforated pipe system is placed at 2 foot intervals, with a return pipe on the top layer. The soil stack is enclosed in visqueen, then hot air is pumped into the piping system which creates the steam that is recycled through the system and carries the contaminants back through the catalytic burner. Because of the catalytic action there are virtually no contaminants exhausted into the atmosphere;
* In situ vitrification: Graphite electrodes are fed into contaminated soil at a specified rate, where high voltage "melts" the organic and inorganic materials in the soil and forms a solid, glasslike substance;
* Land farming: Contaminated soil is deposited and spread out by a farm type spreader on an area of ground dedicated for this purpose. Chemical or manure fertilizer is added to provide a medium for naturally occurring bacteria to thrive. (This part is similar to bio-remediation.) The soil is turned frequently by tillers or rototillers to assist in the aeration of the soil and in the growth of the bacteria. It may take anywhere from a month to two years to cleanse the soil, depending on the volatility of the contaminants. This method is used particularly with soil that is heavily contaminated with oil;
* Mobile incineration: Contaminated soil is loaded onto a conveyor belt which carries it into the hopper of a mobile unit mounted on a lowboy trailer. The unit is heated to burn off the contaminants in the soil. The mobile unit contains a type of dust-collecting mechanism which filters out gases and other nondesirable elements so only clean air enters the atmosphere as the refreshed soil is produced. There are various methods of mobile incineration, but the general process and the end result are similar;
* Soil vapor extraction: A series of holes are bored in the ground and vacuum pumps are used to suck the trapped gases which are drawn through carbon filters for decontamination;
* Stabilization: Concrete landfill cells are created by mixing cement with refuse or other contaminated soil to stabilize the material and reduce the seepage into the surrounding soil; and
* Thermal disabsorption: A process similar to mobile incineration.
Exclusions:
* Worker hours engaged in oil spill cleanup involving diking or ditching work are reported separately in classification 0201.
Notes:
* For rules on assigning and reporting in more than one basic classification, see WAC 296-17-31017 Multiple classifications.
* Classification 0101 is a construction industry classification (see WAC 296-17-31013).
0101-40 Mowing or chemical spraying of roadway median strips, roadsides, and/or power line right of ways
