EPA Project Planning & Contractor Supervision 2 — Questions and Answers
Question 1: What is a 'scope of work' document in the context of a lead abatement contract?
- A warranty for the abatement work
- A detailed description of all surfaces to be abated, methods to be used, and project boundaries (Correct answer)
- A list of materials to be purchased
- A schedule of subcontractor payments
Correct answer: A detailed description of all surfaces to be abated, methods to be used, and project boundaries
The scope of work defines exactly which surfaces will be abated, the methods to be employed, work boundaries, and any exclusions, forming the basis of the abatement contract.
Question 2: When subcontractors are used on a lead abatement project, who bears regulatory responsibility for their compliance with EPA requirements?
- The subcontractors bear sole responsibility
- The property owner
- The certified firm that hired the subcontractors (Correct answer)
- OSHA, not the EPA
Correct answer: The certified firm that hired the subcontractors
The certified firm overseeing the project is responsible for ensuring all subcontractors comply with EPA lead regulations, and can face penalties for subcontractor violations.
Question 3: What should a lead abatement supervisor do if unexpected lead hazards are discovered beyond the original project scope?
- Immediately abate the newly found hazards without informing the owner
- Stop work on the newly discovered areas, notify the owner and regulatory authority if required, and expand the scope of work (Correct answer)
- Cover the unexpected hazards with plastic sheeting and continue
- Ignore them if they are not on the original inspection report
Correct answer: Stop work on the newly discovered areas, notify the owner and regulatory authority if required, and expand the scope of work
Discovering unexpected hazards requires stopping work on those areas, notifying the owner, and potentially expanding the scope of work with regulatory notification, ensuring full compliance.
Question 4: How should an abatement supervisor handle a worker who refuses to wear required respiratory protection?
- Allow the worker to continue if exposure levels are uncertain
- Remove the worker from the lead work area immediately and document the refusal (Correct answer)
- Issue a verbal warning and allow the worker one more chance
- Report the worker to OSHA and continue the project
Correct answer: Remove the worker from the lead work area immediately and document the refusal
A worker refusing required PPE must be removed from the lead work area immediately to prevent exposure; documenting the refusal protects the supervisor and firm from liability.
Question 5: What does 'phased occupancy' mean in a large lead abatement project?
- Billing in multiple installments
- Completing abatement and clearance testing in sections so occupants can return to finished areas while other areas are still being worked on (Correct answer)
- Hiring workers in shifts rather than all at once
- Inspecting the building in phases over multiple years
Correct answer: Completing abatement and clearance testing in sections so occupants can return to finished areas while other areas are still being worked on
Phased occupancy allows occupants to return to completed, cleared sections of a large building while abatement continues in other areas, minimizing displacement time.
Question 6: Which document provides the property owner evidence that lead abatement was completed and the premises are safe for re-occupancy?
- The abatement firm's invoice
- A clearance report issued by a certified inspector or risk assessor after passing clearance tests (Correct answer)
- A letter from the abatement supervisor
- An OSHA compliance certificate
Correct answer: A clearance report issued by a certified inspector or risk assessor after passing clearance tests
A clearance report from a third-party certified inspector or risk assessor, documenting that dust wipe samples passed EPA clearance standards, is the official evidence of safe re-occupancy.
