If you conduct geophysical operations, you must do all of the following:
(a) Use surveying methods that minimize the need for vegetative trimming and removal.
(b) Locate source points using industry-accepted minimum safe-offset distances from pipelines, telephone lines, railroad tracks, roads, power lines, water wells, oil and gas wells, oil- and gas-production facilities, and buildings.
(c) Use equipment and methods that, based upon the specific environment, will minimize impacts to Service-administered lands and waters, and resources of refuges; visitor uses and experiences; and visitor and employee health and safety.
(d) If you use shot holes, you must:
(1) Use biodegradable charges;
(2) Plug all shot holes to prevent a pathway for migration for fluids along any portion of the bore; and
(3) Leave the site in a clean and safe condition that will not impede surface reclamation or pose a hazard to wildlife or human health and safety.
