The Guam Environmental Protection Agency has received U.S. EPA approval to implement the Underground Injection Control (UIC) Program, as mandated by the Safe Drinking Water Act.
The Agency is regulating all applicable activities as set forth in the Guam's Underground Injection Control Regulations. The UIC program requires the issuance of operating permits for all existing injection wells/systems which were constructed prior to the approval of the regulations and are still in operation in addition to those wells/systems constructed after the effective date of the regulations.
The Agency has received an application from Gregorio F. Perez Plaza, Inc. dba: Agana Shopping Center, for a UIC operating permits for twenty-eight (28) drainage wells/systems that are located at Agana Shopping Center, Route 4, Hagatna, Guam. Agana Shopping Center is a retail shopping center with various establishment that includes offices, restaurants, stores, supermarket, and theaters with subsurface drainage wells/systems at the parking areas.
On the basis of a preliminary UIC requirement review, the Administrator proposes to issue UIC permits to allow discharges of stormwater runoff into the injection wells/systems.
The discharges for the proposed injection wells/systems consist of stormwater runoff only. No industrial discharges or any discharges are allowed into the injection wells/systems.
