June 11, 2020
(a) You may file a request for a variance from the requirements of §3200.4 for your approved drilling operations. Your request must include enough information to explain:
(1) Why you cannot comply with the requirements of §3200.4; and
(2) Why you need the variance to control your well, conserve natural resources, or protect public health and safety, property, or the environment.
(b) We may approve your request orally or in writing. If BLM gives you an oral approval, we will follow up with written confirmation.
