3261.21 How do I get approval to change an approved drilling operation§ 3261.21 How do I get approval to change an approved drilling operation?
(a) Send BLM a Sundry Notice, form 3260-3, describing the proposed changes. Do not proceed with the changes until we have approved them in writing, except as provided in paragraph (c) of this section. If your operations such as redrilling, deepening, drilling a new directional leg, or plugging back a well would significantly change your approved permit, BLM may require you to send us a new drilling permit (see 43 CFR 3261.13). A significant change would be, for example, redrilling the well to a completely different target, especially a target in an unknown area.
(b) If your changed drilling operation would cause additional surface disturbance, we may also require you to submit an amended operations plan.
(c) If immediate action is required to properly continue drilling operations, or to protect public health, safety, property or the environment, BLM may provide oral approval to change an approved drilling operation. However, you must submit a written Sundry Notice within 48 hours after we orally approve your change.
