45 CFR § 2105.38
How will fee amounts be determined?
April 14, 2021
(a) The Agency will charge the types of fees discussed in this subpart unless a waiver of fees is required under §2105.37 or has been granted under §2105.43.
(b) Because the types of fees discussed in this subpart already account for the overhead costs associated with a given fee type, the Agency should not add any additional costs to those charges.
