[Effective date: May 28, 1985]

[page 1 of 1]



§550.1 Policy

The Department of Environmental Conservation, having been entrusted with the basic responsibility for administering to and regulating activities relative to the natural resources of oil and gas within the State, does hereby promulgate the following rules and regulations. These have been formulated after consultation with landowners, producers and other interested persons involved and a public hearing relative thereto. The rules have as their objectives:

(a) the fostering, encouragement and promotion of the development, production and utilization of the natural resources of oil and gas in such a manner as will prevent waste;

(b) the operation and development of oil and gas properties in such a manner that a greater ultimate recovery of oil and gas may be had;

(c) full protection of the correlative rights of all owners and the rights of all persons, including landowners and the general public;

(d) similar provisions for the underground storage of gas.

§550.2 Organization

(a) To carry out the functions outlined in section 550.1 of this Part, the Department of Environmental Conservation has created a Bureau of Mineral Resources.

(b) The Bureau of Mineral Resources is headed by a chief who is responsible for the administration and enforcement of all rules, regulations, orders and amendments thereof of the Department of Environmental Conservation relating to the exploration and drilling for, and production, transportation, purchase, processing and storage of oil and gas and the prevention of any pollution resulting therefrom.

(c) The chief of the Bureau of Mineral Resources shall be responsible for the directing, supervising and proper performance of the Bureau of Mineral Resources.

(d) The chief of the Bureau of Mineral Resources is aided by an assistant chief who acts in the former's absence. At those times, the assistant chief bears both the responsibilities and authorities of the chief.

(e) To carry out field responsibilities, the Bureau of Mineral Resources is organized into several regions, each headed by a regional supervisor, who acts as the chief's deputy in all relevant matters.
