7#b7 ,advanced leak detection technology
  7,a7 ,in general ,advanced leak       
detection technology referred to in     
paragraph 7#a7 includes-- 7i7 a high    
sensitivity methane detector mounted on 
a vehicle or aircraft1 including a      
drone1 equipped with ,global            
,positioning ,system technology1 if that
 high sensitivity methane detector and  
,global ,positioning ,system technology 
meet the minimum performance standards  
described in subparagraph 7,b72 and     
7ii7 any other technology or combination

 of technologies that meet the minimum  
performance standards described in      
subparagraph 7,b74  7,b7 ,minimum       
performance standards ,the high         
sensitivity methane detector and ,global

referred to in subparagraph 7,a77i7     
shall1 at a minimum--  7i7 collect      
latitude and longitude coordinates and  
methane concentration data              
simultaneously2  7ii7 measure methane   
concentrations in parts per billion2 and
  7iii7 collect data points at a rate of
 at least twice per second4  7#c7

natural gas when making repairs to the  
pipeline facility2  7#b7 use the best   
available technology1 including1 as     
applicable1 advanced leak detection     
technology described in section         
#fjaji7;h77#b71 to search for and       
identify leaks in the pipeline facility2
  7#c7 develop or participate in a      
replacement or repair program for       
pipeline facilities that-- 7,a7 are of a
 design1 age1 or material known to be   
leaky2 or  7,b7 are known to be leaky   
based on operating history2 and  7#d7   
report to the ,secretary any event that 
involves a release of gas from a        
pipeline facility that results in an
