0101-37 Soil remediation
Applies to establishments engaged in various types of remediation of soil contaminated with hazardous or toxic materials. Soil remediation can take place at the site of the contamination, or the contaminated soil may be hauled to another area for remediation. This classification also includes oil spill cleanup on land. Equipment used will include backhoes and front end loaders, as well as other types of dirt moving equipment.
The methods used for soil remediation 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' 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.
- 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.
- 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.
- Thermal disabsorption: A process similar to mobile incineration.
- 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.
This classification excludes oil spill cleanup involving diking or ditching work which is to be reported separately in classification 0201.
0101-39 Pool or pond excavation
Placement of pool or pond liners
Applies to contractors engaged in the excavation of pools or ponds. Work contemplated by this classification involves excavating or digging of earth to form the hole such as for a swimming pool or pond. Work contemplated by this classification includes excavation of rocks and boulders, removal of tree stumps, clearing or scraping land of vegetation, grubbing, piling or pushing of earth, earth excavation, cutting, filling or backfilling, etc. Equipment used by contractors subject to this classification includes a variety of earth moving equipment such as, but not limited to, shovels, bulldozers, backhoes and dump trucks. This classification includes the placement of plastic pool and pond liners provided it is not in connection with concrete work.
This classification excludes concrete construction which is to be reported separately in the applicable concrete construction classification.
0101-40 Mowing or chemical spraying of roadway median strips, roadsides, and/or power line right of ways
Applies to contractors engaged in mowing, grooming, picking up litter, and chemical spraying of roadway median strips and edges, roadsides, and power line right of ways. Work contemplated by this classification includes spraying chemicals to control weeds and unwanted vegetation, tall grass, brush, brambles and tree seedlings as part of a roadway, roadside or right of way maintenance contract. Equipment used by contractors subject to this classification includes, but is not limited to, a variety of equipment such as backhoes, tractors, push mowers, brush mowers, weed eaters, as well as hand tools such as machetes, sickles, and pruners.
This classification excludes mowing and/or grooming of roadway median strips, roadsides, and power line right of ways when performed by employees of cities, counties, state agencies, or other municipalities which is to be reported in the classification applicable to the type of municipality performing the work; forest, timber or range land contract work which is to be reported separately in the classification applicable to the work being performed; and the felling and removal of trees by chain saw which is to be reported separately in classification 5001.
