Code of Federal Regulations Title 50. Wildlife and Fisheries § 50.29.111 What general facility design and management standards must I meet?

(a) Design, construct, operate, and maintain access to your operational site to cause the minimum amount of surface disturbance needed to safely conduct operations and to avoid areas we have identified as containing sensitive resources.

(b) Install and maintain secondary containment materials and structures for all equipment and facilities using or storing contaminating substances. The containment system must be sufficiently impervious to prevent discharge and must have sufficient storage capacity to contain, at a minimum, the largest potential spill incident.

(c) Keep temporarily stored waste in the smallest area feasible, and confine the waste to prevent escape as a result of percolation, rain, high water, or other causes. You must regularly remove waste from the refuge and lawfully dispose of the waste in a direct and workable timeframe. You may not establish a solid waste disposal site on a refuge.

(d) Use engines that adhere to applicable Federal and State emission standards.

(e) Construct, maintain, and use roads in a manner to minimize fugitive dust emissions.

(f) Design, operate, and maintain your operations and equipment in a manner consistent with good air pollution control practices so as to minimize emissions and leaks of air pollutants and hydrocarbons, including intentional releases or flaring of gases.

(g) Control the invasion of noxious and invasive plant and animal species in your area of operations from the beginning through final reclamation.

(h) Avoid conducting ground-disturbing operations within 500 feet of any surface water, including an intermittent or ephemeral watercourse, or wetland, or any refuge structure or facility used by refuges for interpretation, public recreation, or administration. We may increase or decrease this distance consistent with the need to protect Service-administered structures or facilities, visitor uses or experiences, or visitor or employee health and safety;  or to ensure that you have reasonable access to your non–Federal oil and gas. Measurements for purposes of this paragraph are by map distance.
