James Stark 7. DRMS - NECC is proposing to drill exploration hole NE -01 -12 in the AVF along the Purgatoire River. This hole will be different from exploration holes drilled in bedrock and may require a different sealing plan. Please provide a description of how NECC will seal exploration hole NE- 01 -12, which is located in the Purgatoire River AVF, to ensure the protection of the essential hydrologic Junction of the AVF. Please include a generalized description of this sealing on permit page 2.05 -54. NECC - As explained above NE -01 -12 is not located in an AVF. In any case, it is standard practice of Agapito to fill all exploration holes with cement. Agapito has the drilling company mix neat cement and pump from bottom up to surface. To ensure all water is lifted out of the hole. 8. DRMS' - In the cover letter NECC states that, while exploration hole NE -01 -12 will be drilled in the Purgatoire River AVF, it will be more than 100 feet from the Purgatoire River. Proposed Map 20 indicates that the location of exploration hole NE -01 -12 is approximately 500 feet from the Purgatoire River. The current proposed location for exploration hole NE- 01 -12 is acceptable to the Division. However, pursuant to Rule 4.05.18, please ensure that exploration hole NE -01 -12 remains more than 100 feet away, from the Purgatoire River. NECC - NECC will ensure that exploration hole NE -01 -12 remains more than 100 feet away from the Purgatoire River. Sincerely, J. E. over, P.E.
