Post-RA O&M Cost Elements
Cost Element
Description
Includes post construction O&M (separate for each subsystem technology) of
342XX.11
the plant facility, based on the volume of waste material treated, including
Biological Treatment
portable treatment equipment which is charged on a time basis and can be used
on more than one project (342XX.11.(01.-14.)). Includes a separate item for
the yearly post construction O&M of a permanent plant facility
(342XX.11.50.). Biological treatment is the microbial transformation of
organic compounds. Biological treatment processes can alter inorganic
compounds such as ammonia and nitrate, and can change the oxidation state of
certain metal compounds. Includes in-situ biological treatment such as land
farming as well as activated sludge, composting, trickling filters, anaerobic,
and aerobic digestion. Includes process equipment and chemicals required for
treatment.
For transportation see "Transport to Treatment Plant"
(342XX.05.11, 342XX.06.08, 342XX.08.03 or 342XX.09.04).
Includes post construction O&M (separate for each subsystem technology) of
342XX.12
the plant facility, based on the volume of waste material treated, including
Chemical Treatment
portable treatment equipment which is charged on a time basis and can be used
on more than one project (342XX.12.(01.-14.)). Includes a separate item for
the yearly post construction O&M of a permanent plant facility
(342XX.12.50.). Chemical treatment is the process in which hazardous wastes
are chemically changed to remove toxic contaminants from the environment.
Type of treatment included in this system are oxidation/reduction, solvent
extraction, chlorination, ozonation, ion exchange, neutralization, hydrolysis,
photolysis, dechlorination, and electrolysis reactions. Includes process
equipment and chemicals required for treatment. For transportation see
"Transport to Treatment Plant" (342XX.05.11, 342XX.06.08, 342XX.08.03 or
342XX.09.04).
Includes post construction O&M (separate for each subsystem technology) of
342XX.13
the plant facility, based on the volume of waste material treated, including
Physical Treatment
portable treatment equipment which is charged on a time basis and can be used
on more than one project (342XX.13.(01.-32.)). Includes a separate item for
the yearly post construction O&M of a permanent plant facility
(342XX.13.50.). These treatment processes are the physical separation of
contaminants from solid, liquid or gaseous waste streams. The treatments are
applicable to a broad range of contaminant concentrations. Physical treatments
generally do not result in total destruction or separation of the contaminants in
the waste stream, consequently post-treatment is often required. Type of
physical treatment included in this system are filtration, sedimentation,
flocculation, precipitation, equalization, evaporation, stripping, soil washing,
and carbon adsorption. Includes process equipment and chemicals required for
treatment.
For transportation see "Transport to Treatment Plant"
(342XX.05.11, 342XX.06.08, 342XX.08.03 or 342XX.09.04).
