 strictly confined within the production site easement boun- 

 daries. Vegetation damage, equipment and supply storage, and 

 removal of fill materials from outside these boundaries are 

 prohibited, unless otherwise authorized in writing by the land 

 manager. 



U-43P The permittee shall provide the land manager with a design 



which restricts the pad size to the mininum area required to 

 conduct processing operations, store equipment and supplies, 

 and contain waste materials. Pad easement shall not exceed 

 5,000 m2 (1.25 acres) unless otherwise authorized in writing by 

 the land manager. 



L)-46P All primary drainage patterns within the production facility 

 easement shall be maintained uninterrupted by the use of con- 

 duit, culverts, bridges, or other applicable techniques as 

 specified and authorized by the land manager. 



Restoration. 



U-44P Upon completion of any oil and gas activity which no longer 



requires the use of an existing processing site, the permittee 

 shall, unless otherwise authorized by the land manager, remove 

 the pad and restore the entire easement to its original precon- 

 struction condition or better, as specified by the land manager. 

 Restoration measures shall include, but are not limited to: 

 reestablishment of former surface contours, restoration of soil 

 structure, fertilization, revegetation with native flora, restor- 

 ation of former drainage patterns, and removal of excess fill 

 materials from the refuge. 



U-45P Following removal of production facilities, the land manager 



may conduct an on-site inspection to verify that restoration or 

 mitigation of any environmental damages has been satisfactorily 

 completed and may, at that time, require additional conservation 

 measures necessary to satisfy permit requirements.
