PHMSA is committed to providing pipeline related data to pipeline operators complying with integrity management programs and to community officials. PHMSA will verify the contact information provided by all requesting individuals. THERE HAVE BEEN NO UPDATES TO USA DATA LAYERS SINCE THEIR ORIGINIAL RELEASE.
