z The agreement calls for excavation and replacement of the pipeline before and after subsidence occurs. The pipeline must be replaced in accordance with applicable Department of Transportation regulations which require a minimum three feet of cover over the pipe. The CEC/Amoco agreement specifies that this three feet of cover material will be the material excavated from the pipe trench. Amoco or CEC will then seed the reclaimed pipe corridor with the rangeland seed mix in the Eagle mine permit or the cover crop mix on the disturbed ground, where appropriate. This burial of the pipeline and reseeding will restore the value of the disturbed land and assure that any reasonably foreseeable postmine use of the land is feasible, as required by Rule 4.20.1. 2. Existing regulatory authority of other government agencies over oil and gas pipelines. While our regulations ultimately hold CEC liable for mitigating structural damages and restoring the value of land affected by subsidence, at least two other government agencies also have jurisdiction over the proposed pipeline work and potential oil spills. The U.S. Department of Transportation regulations in 49CFR Part 195 include standards for pipeline construction, including the three foot cover requirement mentioned above. Associated DOT regulations also address response plans and damage prevention programs for pipeline operators. The Colorado Department of Health, Water Quality Control Division would be involved in any potential oil spill resulting from subsidence or pipeline excavation. The CDOH approved CEC's amendment to the mine's SPCC plan in regard to the containment sumps downhill from the pipeline. I believe the proposed pipeline work meets the regulatory requirements of DMG, OSM, DOT, and CDOH. 3. Existing "policy" and court rulings in regard to liability for subsidence damage. I did some library and phone research in an attempt to determine what the current status of the regulatory world's policy was in regard to the question, "Does land which is disturbed as part of subsidence control work need to be bonded and included in the mine's ten year liability?". As far as i can determine,
