What is one of the two situations where a compliance letter can be issued without taking dust samples?

In the context of lead risk assessment and inspection, a compliance letter signifies that a property meets safety standards regarding lead exposure. One situation where this letter can be issued without taking dust samples is during a risk assessment conducted in accordance with a Previous Compliance Assessment Document (PCAD) when there are no new hazards identified.

When a PCAD indicates that past assessments found no hazardous levels of lead and that there have not been changes or new hazards introduced (such as renovations or new occupants), the inspector can confidently issue a compliance letter without the need for further dust sampling. This is based on the assumption that the previously documented conditions remain valid and that no new lead exposure risks have arisen.

This practice acknowledges that continuous monitoring and documentation are essential for maintaining lead safety, and relying on past results is appropriate in stable situations without the introduction of new hazards. Therefore, for properties that are well maintained and have a history of compliance, issuing a compliance letter without new sampling is justified.
