PART 149--SOLE SOURCE AQUIFERS--Table of Contents
 
  Subpart A--Criteria for Identifying Critical Aquifer Protection Areas
 
Sec. 149.3  Critical Aquifer Protection Areas.

    A Critical Aquifer Protection Area is either:
    (a) All or part of an area which was designated as a sole or 
principal source aquifer prior to June 19, 1986, and for which an 
areawide ground-water quality protection plan was approved, under 
section 208 of the Clean Water Act, prior to that date; or
    (b) All or part of a major recharge area of a sole or principal 
source aquifer, designated before June 19, 1988, for which:
    (1) The sole or principal source aquifer is particularly vulnerable 
to contamination due to the hydrogeologic characteristics of the 
unsaturated or saturated zone within the suggested critical aquifer 
protection area; and
    (2) Contamination of the sole or principal source aquifer is 
reasonably likely to occur, unless a program to reduce or prevent such 
contamination is implemented; and
    (3) In the absence of any program to reduce or prevent 
contamination, reasonably foreseeable contamination would result in 
significant cost, taking into account:
    (i) The cost of replacing the drinking water supply from the sole or 
principal source aquifer, and
    (ii) Other economic costs and environmental and social costs 
resulting from such contamination.
