Civilian Air Force Group Provides Pipeline Oversight

The Dominion Pipeline Monitoring Coalition (DPMC), headed by retired UVA Senior Scientist Rick Webb, seeks to keep  Virginia politicians, government bodies, and Dominion on their toes concerning environmental effects of pipelines and natural gas infrastructure. To identify potential problems, DPMC runs a civilian air force that takes photographs of existing and planned infrastructure sites. In their latest investigative effort, the DPMC… Read more
