43 CFR 3281.16 - When must a Plan of Development be submitted to BLM?
(b) Subsequent Plans of Development that were not already provided must be submitted to address future unit activities to be conducted throughout the term of the unit agreement. For example, if the Plan only addressed activities until a unit well is completed, the subsequent Plan must address activities including the drilling of additional unit wells until a producible well is completed. Once a producible well is completed, the Plan or subsequent Plan must address those activities related to utilizing the resource.
(c) There is no requirement to submit a Plan of Development once unitized resources begin commercial operation.
