An Area of Review Variance Methodology
When the Underground Injection Control (UIC) Regulations were promulgated in 1980, existing Class II injection wells operating at the time the regulations became effective were excluded from Area of Review (AOR) requirements. The U.S. Environmental Protection Agency has expressed its intent to revise the regulations to include the requirement for AORs of such wells. A methodology for identifying areas that would be eligible for variance from AOR requirements has been developed. The methodology provides for evaluation of an area for variance based upon five criteria.
