AUSTIN, Texas (March 30, 2015) – According to a newly released environmental analysis, Ozone NAAQS Proposed Rule – Evaluation of the Science, the EPA’s recommendation to lower the current ozone standard is unsubstantiated by the evidence provided by the agency. The extensive review, conducted by Zephyr Environmental Corporation and commissioned by the Texas Pipeline Association, revealed that the current standard of 75 parts per billion continues to be protective of public health and welfare, with an adequate margin of safety.

On November 25, 2014, EPA proposed to update the air quality standard for ground-level ozone. EPA claims that the proposed updates would better protect the public and the environment, however, the agency hasn’t identified any studies that indicate a clear causal relationship between ozone concentrations less than 88 ppb and clinically relevant adverse human health impacts.

“Zephyr’s analysis confirms that EPA’s proposed rule is unsupported,” said Thure Cannon, president of TPA. “EPA has failed to point to any persuasive body of scientific evidence supporting its proposal. Unnecessarily tightening the ozone standard would simply add to the already cumbersome bureaucracy tied to the midstream industry and other industries and would impose enormous additional costs, with no offsetting benefit.”

TPA submitted the analysis, in addition to written comments opposing the proposed rule to EPA, on March 13, 2015. After reviewing the comments submitted by TPA and other members of the public, the agency will make a final decision on the ozone standard, which is expected in October 2015.
