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 E.C. Development Corporation for UIC operating permits of three (3) injection systems which are located at the Calvo Commercial Center, Harmon Loop Road, Dededo, Guam. The Calvo Commercial Center is a business center for broadcasting, cable services, finncial institution, beauty salon, and a dialysis center. The center has subsurface drainage 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 systems.
The discharges for the proposed injection systems consist of stormwater runoff only. No industrial discharges or any discharges are allowed into the injection systems.
The permits for the above application will require:
(1) only stormwater runoff to be discharged into the injection systems
(2) semi-annual monitoring of water quality for MBAS, Oil and Grease, NO3-N, Endrin, Lindane, Toxaphene, 2, 4-D, 2, 4, 5-TP Silvex, Heptachlor, Methoxychlor, Lead, Benzene, Ethylbenzene, Xylene, Toluene, MTBE, Boron, COD, and pH;
(3) assurance regarding repairs, replacement, or abandonment of the wells/systems in the event of failure;
(4) a laboratory analysis report of runoff water actually taken from the designated sampling points of the system; and
(5) compliance with other UIC requirements.
