What is the essential requirement for interim controls that does not involve abatement?

Interim controls are strategies designed to reduce lead exposure without the need for complete removal or abatement of lead-based paint. The core requirement for these interim measures is to utilize non-permanent means to manage lead exposure effectively. This can include actions such as regular cleaning, repairing surfaces to prevent deterioration, and implementing practices that minimize lead dust or hazards while maintaining the existing lead-based paint.

The approach focuses on managing and minimizing risk rather than removing lead hazards entirely, which differentiates interim controls from full abatement that often involves permanent solutions. The emphasis on non-permanent means is crucial because it allows for flexibility and cost-effectiveness while ensuring that lead hazards are controlled until an appropriate permanent solution can be implemented.
