         &EPA  The  Class   V   Rule
                             A  Quick Reference Guide  for Regulators
    Title of Rule:
    Purpose:
    General Description:
Revisions to the Underground Injection Control Regulations for Class V Wells
64 FR 68545-68573, December 7,1999.

Prevent contamination of underground sources of drinking water by limiting injection of
wastes through Class V wells.

Adds requirements for two sub-categories of Class V wells: large-capacity cesspools and
motor vehicle waste disposal wells. Links Class V program to source water assessment program.
                                              Rule Requirements
               Large-capacity cesspools
Definition: typically dry wells that receive sanitary waste from multiple
dwellings and community or regional establishments.

 New large-capacity cesspools banned nationwide as of April 5, 2000

 Existing large-capacity cesspools closed by April 5, 2005

 Owners or operators notify the UIC Program Director 30 days
  prior to closing their large-capacity cesspool
                                           Motor vehicle waste disposal wells
                                 Definition: receive or have received fluids from vehicular repairs or
                                 maintenance activities, such as auto body repair, automotive repair, car
                                 dealerships, or other vehicular repair work.
                                   New motor vehicle waste disposal wells banned nationwide as of
                                   April 5, 2000
                                   Existing motor vehicle waste disposal wells banned in regulated
                                   areas.  States may allow owners and operators to seek a waiver
                                   from the ban and obtain a permit.
                                   Owners or operators notify the UIC Program Director 30 days
                                   prior to closing their well
 Minimum permit requirements for existing motor vehicle waste disposal wells

 1.  Fluids must meet Maximum Contaminant Levels (MCL) and other health-based standards at point of injection.
 2.  Best Management Practices must be specified.
 3.  Monitoring requirements must be specified to characterize the quality of the injectate and sludge, both initially and on an ongoing basis.
Requirements for existing motor vehicle waste disposal wells would be phased-in as follows:

First - in source water protection areas for community and non-transient non-community water systems that use ground water as a source of drinking
water. These areas are being delineated and assessed as required by 1453 of the Safe Drinking Water Act and are called ground water protection areas.

Second - in other sensitive ground water areas that States identify as being crucial for protecting underground sources of drinking water. These areas
may include areas overlying sole source aquifers, karst aquifers, or other sensitive or vulnerable hydrogeologic settings such as glacial outwash
deposits, eolian sands and fractured bedrock.

If a State does not complete its assessments for ground water protection areas or delineate other sensitive ground water areas by January 1, 2004, the
rule requirements apply statewide.
