Regulation of Air
Impacts EPA Proposal – Sampling of Comments, cont’d: North Central Texas Council of Governments: VOC controls should not apply to storage tanks at 6 tpy threshold, but at 15 tpy (“most cost-effective level” ) Interstate Natural Gas Association of America (INGAA): “EPA’s recently proposed oil and natural gas regulations are portrayed as regulating emissions of [VOCs]. These rules would have far- reaching impacts on our industry, yet, for natural gas transmission and storage companies, VOC emissions are relatively minimal. This leads us to believe that the actual aim of these proposed standards is to regulate greenhouse gases (GHGs) . . . . [INGAA] strongly objects to these proposed regulations because they do not address VOCs but instead clearly target GHG emissions.” “[T]he cost to comply would be very high. . . .
