# Disposal standards for owners/operators of non-municipal non-hazardous waste disposal units that receive Conditionally Exempt Small Quantity Generator (CESQG) waste.
**CFR Correction**
In Title 40 of the Code of Federal Regulations, parts 190 to 259, revised as of July 1, 2003, on page 376, § 257.5 is corrected by reinstating the definition of *Uppermost aquifer* to read as follows:
§ 257.5
(b) * * *
*Uppermost aquifer* means the geologic formation nearest the natural ground surface that is an aquifer, as well as, lower aquifers that are hydraulically interconnected with this aquifer within the facility's property boundary.
