RESOURCE REPORT 6 GEOLOGICAL RESOURCES SUMMARY OF FILING INFORMATION INFORMATION: DATA SOURCES: Minimum Requirements to Avoid Rejection 1. Identify the location (by milepost) of mineral resources and any planned or active Section 6.3 surface mines crossed by the proposed facilities. ( 380.12(h)(1&2)) Section 6.4 Describe hazards to the facilities from mining activities, including subsidence, blasting, slumping or landsliding or other ground failure, 2. Identify any geologic hazards to the proposed facilities. ( 380.12(h)(2)): Section 6.4 For the offshore this information is needed on a mile-by mile basis and will require completion of geophysical and other surveys before filing. 3. Discuss the need for and locations where blasting may be necessary in order to Section 6.5 construct the proposed facilities. ( 380.12(h)(5)). 4. For LNG projects in seismic areas, include the materials required by Data Not Applicable Requirements for Seismic Review of LNG Facilities, NBSIR84.2833. ( 380.12(d)(5)) 5. For underground storage facilities, how drilling activity by others within or Section 6.7 adjacent to the facilities would be monitored, and how old wells would be located and monitored within the facility boundaries. ( 380.12(h)(6)) 6. Identify any sensitive paleontological resource areas crossed by the proposed Section 6.6 facilities. (Usually only if raised in scoping or required by land managing agency.) 7. Briefly summarize the physiography and bedrock geology of the project area. Section 6.1 Section 6.2 8. If the application is for underground storage facilities: Section 6.7 Describe monitoring of potential effects of the operation of adjacent storage or Section 6.8 production facilities on the proposed facility, and vice versa; Describe measures taken to locate and determine the condition of old wells within the field and buffer zone and how the applicant would reduce risk from failure" of known and undiscovered wells: and, Identify and discuss safety and environmental safeguards required by state and Federal drilling regulations RR-6 Amendment Geological Resources.docx 3/24/2011 2:50 PM TABLE OF CONTENTS 6.0 INTRODUCTION............................................................................................. 1 6.1 REGIONAL GEOLOGY .................................................................... 1 6.2 LOCAL GEOLOGY .......................................................................... 2 6.2.1 Surface Geology.........................................................................2 6.2.2 Stratigraphy ................................................................................3 6.2.3 Crowville Salt Dome Geology ...................................................3 6.3 MINERAL RESOURCES ................................................................... 5 6.3.1 Oil and Natural Gas ...................................................................5 6.3.2 Surface Mines ............................................................................5 6.4 GEOLOGIC H
