• Generally Not Eligible: Reimbursement for regular pay of exempt employees performing Category B work (emergency work) is typically not allowed.
• Internal Policy Check: You should refer to your organization's pay policy that existed before the disaster. This policy might have provisions for overtime pay or compensatory time for exempt employees in such situations.
• FEMA Reference: The FEMA Public Assistance Program and Policy Guide (PAPPG) provides specific guidance.  Chapter 2, Section V. Costs Eligibility details eligibility criteria for applicant (force account) labor.  Subpart A, Section 2 focuses on eligibility based on employee type and work performed, specifically for supervisors.

Here are some additional points to consider:

• Overtime for Exempt Employees: While regular pay might not be reimbursed, some FEMA programs might allow reimbursement for overtime pay of exempt employees engaged in Category B work, depending on your internal policy.
• Clarity on Supervisor Eligibility: The FEMA reference you provided (Chapter 2, Section V, Subpart A, Section 2) might offer specific details on supervisor eligibility, which could be relevant for some exempt employees with supervisory duties.

Overall, for a definitive answer on exempt employee reimbursement under Category B work, it's crucial to consult both your pre-disaster internal pay policy and the specific FEMA PAPPG guidelines relevant to your situation.  There might be exceptions or specific circumstances that could affect eligibility.
