IT APPEARING THAT:

1. ARCO Alaska, Inc. (ARCO) requested on February 6, 1987 the Alaska Oil and Gas Conservation Commission to authorize the continued use of BR WD-1 as a disposal well in the Beluga River Gas Field. ARCO will inject non-hazardous waste fluids generated by normal drilling and production operations.

2. Notice of an opportunity for a public hearing on March 26, 1987 was published in the Anchorage Daily News on February 23, 1987.

3. No protest or request for a public hearing was timely filed. Accordingly, the Commission will, in its discretion, issue an order without a public hearing.

FINDINGS:

1. ARCO, as operator of the Beluga River Gas Field, currently is authorized by EPA permit AK-2D0001-I, issued in conformance with the Safe Drinking Water Act as amended 42 USC 300f et seq, to utilize well BR WD-1 for injection of non-hazardous liquid wastes into the Sterling formation below the measured depth of 3060 feet.

2. All aquifers below 3030 feet within a one-mile radius around the well bore of well BR WD-1 Beluga River Gas Field, are exempted in E.P.A. Permit AK-2D0001-I for Class II injection activities.

3. Permeable strata, that will accept injected fluids, are present below 3060 feet in well BR WD-1.

4. A series of confining strata are present above 3060 feet in well BR WD-1 that will prevent upward movement of the injected waste fluids into non-exempt aquifers.

5. The strata into which fluids are to be injected will accept fluids at injection pressures which are less than the fracture pressure of the injection strata and their confining formations.

6. To ensure that waste fluids are confined to injection strata, the mechanical integrity of BR WD-1 will be demonstrated periodically and monitored routinely for disclosure of possible abnormalities in operating conditions.

7. BR WD-1 is constructed and has been tested in conformance with the requirements of 20 AAC 25.412.

CONCLUSIONS:

The geologic sequence present at the well site and maintenance of the mechanical integrity of well BR WD-1 will prevent movement of injected waste fluids into non-exempt aquifers.

NOW, THEREFORE, IT IS ORDERED THAT:

Non-hazardous oil field waste fluids may be injected in conformance with Alaska Administrative Code Title 20, Chapter 25, for the purpose of disposal into the Sterling formation below the measured depth of 3060 feet in well BR WD-1, Sec. 13, T13N, R1OW, S.M., Beluga River Gas Field.

DONE at Anchorage, Alaska and dated March 11, 1987.
