Water: Class V Wells
Class V Regulations
In 1999, EPA added new requirements for large-capacity cesspools and motor vehicle waste disposal wells. The Class V Rule prohibited new large-capacity cesspools and new motor vehicle waste disposal wells nationwide as of April 2000. The rule also phased out existing cesspools nationwide by April 2005. Operators of existing motor vehicle wells in regulated areas must either close their wells or obtain a permit.
