Guam - The Guam Environmental Protection Agency board listened to closing arguments Monday night regarding the appeal of Cyfred's denied proposed pilot sewer system for the sewerless Gill-Baza Subdivision. GEPA spokesperson Tammy Jo Anderson Taft says GEPA is most concerned as the property sits above the island's northern aquifer, where we get more than 80 percent of our drinking water

"In Guam EPA's opinion," she said, "it's not a sewer system it's an individual wastewater system, which is essentially a septic tank in a leaching field which is by regulation not allowed on lots less than a half-acre size for various reasons including density things like that."

The GEPA board has instructed their hearing officer to prepare their decision in writing to be reviewed at GEPA's November board meeting.
