B-50P Containment and cleanup of an accidental spill shall be con- 

 ducted as soon as possible following its discovery, unless 

 otherwise specified by the land manager. 



Methods and techniques. 



B-51P In the control of spilled oil or oil-field substances, no dis- 

 persants, emulsifiers, or other chemical agents shall be used 

 without permission in writing from the land manager as to the 

 type or kind of chemical to be used and the rate, time, and 

 method of application. 



B-52P In the event of an accidental spill or discharge of oil or any 

 other petrochemical substance, the permittee shall take such 

 measures as may be necessary or requested by the land manager 

 to disperse and pervent waterfowl, wading birds, and shorebirds 

 from using oil-contaminated marsh areas. 



B-54P The permittee shall be permitted to immediately burn any oil 

 accidentally escaping anywhere in the field. 



B-55P The permittee shall take all reasonable percautions necessary 

 during the spill containment and cleanup phases to minimize 

 disturbances to the marsh surface, existing drainage patterns, 

 and marsh vegetation. 



B-56P The permittee shall take all necessary percautions to avoid 



damaging the root systems of oil-contaminated marsh flora. If 

 such vegetation is mechanically removed, only the aerial por- 

 tions should be taken. 



Restoration. 



B-57P Following the cleanup phase of a brine or oil spill, the per- 

 mittee shall, unless otherwise authorized by the land manager, 

 restore the affected area to its original preaccident or better 

 condition as specified by the land manager. Restoration mea- 

 sures shall include, but are not restricted to, reestablishment 

 of former drainage patterns and revegetation with native flora.
