This case addresses violations of the Safe Drinking Water Act's Underground Injection Control regulations by the Gay and Robinson company on Kauai. EPA's regulations banned the use of large capacity cesspools after April 2005. A large-capacity cesspool is one that discharges untreated sewage from multiple dwellings, or from a non-residential location that serves 20 or more people per day. Gay and Robinson agreed to pay a penalty of $110,000 for failing to close 40 large-capacity cesspools on Kauai. EPAÂs enforcement Order required the company to close its Kaumakani Avenue large-capacity cesspool and the Camp 6 cesspools by May 2010, and its large-capacity cesspools at Pakala Village by September 2011.
