More than 100 House lawmakers consistently voted for legislation to weaken safeguards against toxic chemicals, according to a recent report by the Environmental Working Group (EWG) Action Fund released Tuesday.

The political arm of the environmental group found in its first scorecard of the voting patterns of lawmakers on chemical policy measures that a number of largely Republican lawmakers voted for measures that aim to weaken chemical standards or place obstacles in front of new chemical protections.

Looking at 17 separate bills and amendments voted on during the 114th and 115th Congresses, the report found that over 100 lawmakers voted for these measures at every chance they got. Additionally, the analysis found that 140 House members voted against toxic chemical safeguards in every of the measured instances. In contrast, 149 members voted consistently for chemical safety protections.

All three politicians were among a group that introduced their own bills that in some fashion could make it easier for chemicals to pass regulatory hurdles.

According to EWG Action Fund, Lewis introduced a bill that could require agencies to submit chemical safety plans for congressional review, which the group says could delay or block the implementation of the safeguards.

A spokeswoman for Lewis's office pushed back against the characterization, saying the bill would only affect guidance documents believed to lead to an annual effect of at least $100 million, and that there is "no reason to believe" that chemical safety measures would be one of them.

"It’s no surprise that the EWG, which has a long history of supporting candidates and controversial causes backed by more extreme environmental groups, think that more transparency and taxpayer accountability are negatives," said Lewis in a statement to The Hill.

"EWG has no interest in the open process my legislation provides, they are clearly more interested in putting workers at Pine Bend out of work.”

EWG Action Fund is the advocacy arm of the nonprofit environmental group that focuses on raising money and legislative awareness on a trove of environmental and chemical issues.

Their report also highlighted Republican lawmakers who voted for legislation that would increase chemical standards, including Rep.

Concerns about chemical safety standards have grown under the Trump administration as the Environmental Protection Agency (EPA) and other departments move to implement a number of new policies critics say weaken environmental protections.

The EPA this summer has been criticized over its new plans to regulate asbestos. Asbestos is largely not banned on the federal level, but a 2016 law gave the EPA authority to prohibit the carcinogen.

The EPA’s proposal, released in June, was criticized as opening the door to widespread use of asbestos. EPA officials ardently denied the accusations, saying the proposed regulations would effectively ban the substance.
