Which actions are part of interim controls or temporary abatement?

The option stating specialized cleaning and maintenance as part of interim controls or temporary abatement is correct because these actions are designed to reduce or manage lead hazards while more permanent solutions are developed and implemented. Interim controls typically involve a range of measures that may include the frequent cleaning of surfaces to reduce lead dust, maintaining painted surfaces to prevent deterioration, and ensuring that living environments remain safe until full lead remediation can take place.

Specialized cleaning is critical in environments where lead is present, as it helps to manage the immediate risks associated with lead exposure, especially for children and pregnant women. Maintenance ensures that any wear and tear on surfaces that could release lead into the environment is addressed proactively.

The other options, while they touch on actions related to lead hazard management, do not encompass the broader range of activities classified as interim controls. For instance, ongoing monitoring alone does not actively reduce exposure risks; removal of soil focuses on one specific area without addressing overall hazard management; and repainting, while a maintenance option, doesn't cover the comprehensive measures that specialized cleaning and maintenance provide to manage lead hazards effectively.
