EPA Transparency Rule Will Bolster Science and Improve Rulemaking

When Rules are Based on the Best Available Data, Regulations are More Effective

Transparency is a cornerstone of the scientific process and a well-recognized goal long-extolled within the scientific community. As a 2014 editorial in the British publication Nature Geosciences explained, “Science thrives on reproducibility.” And reproducibility in science can only exist when researchers have access to two things: “full disclosure of the methods used to obtain and analyse data, and availability of the data that went into and came out of the analysis.” A recently proposed Environmental Protection Agency (EPA) rule to promote transparency of scientific data underlying major regulations would help advance this goal in the realm of public policy.

Yet the EPA rule has proven highly controversial because of political and ideological influences. On one side are those who advocate stringent regulations that would err on the side of caution, and on the other are those who seek to streamline and reduce regulatory burdens. However, the rule’s ultimate goal is not to determine how much regulation we will have, but whether the regulations will be effective and necessary to achieve public health and environmental goals. By helping ensure the underlying science is valid, transparency will increase the probability that regulations will actually generate public health benefits and not unintentionally undermine public health and well-being.

Arguments against the rule focus on privacy concerns as well as doubts whether transparency of regulatory science is attainable, and appear to be based on misinformation about what the rule actually does. As the following shows, the rule is actually far more modest and flexible than depicted by its critics, and its goals are in fact achievable.

Overview of the Transparency Rule. In April 2018, then-EPA Administrator Scott Pruitt proposed the rule “Strengthening Transparency in Regulatory Science,” which was modeled after the concepts underlying the Honest and Open New EPA Science Treatment (HONEST) Act (H.R. 1430, S. 1794.). The text of the rule is different from that of the HONEST Act, limiting the scope and allowing for exceptions.

The rule affords the EPA administrator considerable leeway to permit regulators to use research in cases where privacy or other concerns limit public availability. In fact, under some laws, such as the newly reformed Toxic Substances Control Act, the EPA must use such research if it constitutes the “best available science” on an issue. In that case, even if data were not fully available, the agency would still be required to rely on those critical studies. However, in cases where data can be more transparent without privacy concerns, the EPA could not refuse to release the data on arbitrary grounds.

A few key features of the rule include the following:

  • The scope of science to which the rule applies is limited. The rule covers “dose response data and models underlying pivotal regulatory science that are used to justify significant regulatory decisions regardless of the source of funding or identity of the party conducting the regulatory science.” Basically, that means the rule covers the key scientific studies the EPA uses to justify major regulations—those expected to impose costs of $100 million or more a year or that are expected to have other significant adverse impacts. Accordingly, it does not cover every EPA regulatory activity, such as routine permitting decisions, voluntary initiatives programs, or research programs. However, any EPA research used to justify major rules would need to meet transparency standards.
  • The rule protects privacy and confidential business secrets. It specifically directs the EPA to ensure data it relies upon is “publicly available in a manner sufficient for independent validation,” and to do so “in a fashion that is consistent with law, protects privacy, confidentiality, confidential business information, and is sensitive to national and homeland security.”
  • The rule allows the EPA to rely on research that is not publicly available in certain situations. The rule specifically stipulates that the EPA can still use research that the agency cannot make publicly available in cases when it is “not feasible” to do so in a way that is, again, “consistent with law, protects privacy and confidentiality, and is sensitive to national and homeland security.”

Improving transparency is an achievable goal. Transparency in scientific research has never been particularly controversial, and ongoing efforts to improve transparency prove that greater transparency is achievable. As the previously cited Nature Geoscience editorial proclaimed: “The question is no longer whether research data should be shared, but how to make effective data sharing a common and well-rewarded part of research culture.”

Similarly, scientists Chris Chambers of Cardiff University and Brian Nosek of the University of Virginia explain in the Guardian:

Transparency and reproducibility are the beating heart of the scientific enterprise. Transparency ensures that all aspects of scientific methods and results are available for critique, compliment, or reuse. This not only meets a social imperative, it also allows others to test new questions with existing data, makes it easier to identify and correct errors, and helps unmask academic fraud. Transparent practices such as sharing data and computer code, in turn, safeguard reproducibility: the idea that for a scientific observation to count as a discovery it must reveal something real and repeatable about the natural world.

Yet much scientific research does not achieve the goals of transparency for a number of reasons. Chambers and Nosek explain that transparency has become “undervalued” because researchers want to get published, and “the fierce competition of academia rewards those who secure large grants and publish innovative—if tentative—findings in prestigious journals, not scholars who instead focus on being transparent and careful.” As a result, researchers often avoid transparency out of fear that their novel findings may eventually be proven wrong when someone tries to replicate their work.

This reality has fostered both unintentional bias and scientific mischief, including the propensity for researchers to work the data until it generates a positive finding. As James Mills of the National Institute of Child Health and Human Development lamented back in 1993 in the New England Journal of Medicine: “‘If you torture your data long enough, they will tell you whatever you want to hear’ has become a popular observation in our office.” The scope of this problem is also detailed by the National Association of Scholars in its recent report, The Irreproducibility Crisis of Modern Science. The authors highlight one outrageous case where Professor Brian Wansink, head of Cornell University’s food behavior research lab, literally bragged in a blog post that he had schooled one of his students on how to churn data to generate positive results and get them published.

Even when researchers do not torture data, many positive associations will occur by mere chance or unintentional biases. Stanford Professor of Medicine John Ioannidis demonstrated in a research article in 2005 that most published research findings are false positives. He explained: “Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias.”

There are a number of other factors that reduce transparency even among researchers who strive to meet high standards. In an article for Nature, the authors point out that researchers are sometimes reluctant to share data for three reasons:

First, high-quality data are hard to obtain. Researchers should expect their fieldwork to yield one or several primary publications. The originality of these publications might be jeopardized if the data are widely available before they are published, or if individual data sets are amalgamated in large collective synthesis publications. The reluctance towards making hard-earned data publicly available is understandable—at least as long as the measurements have not been sufficiently exploited by those who obtained them.

Second, data are context dependent. Without appropriate contextual information, for example metadata regarding locations, methods and shortcomings, they can easily be misinterpreted and misused. Opening data sets to other researchers means that the circumstances of collection—known by those who performed the measurements—need to be carefully recorded and communicated.

The third factor is related to the previous one: significant effort is often necessary to prepare the data for reuse before they can be made available to the scientific community. In addition to contextualizing data, formats may have to be adjusted and a point of contact may be necessary in case there are questions.

However, these challenges are not an excuse for continued lack of transparency. Rather, the Nature article authors make recommendations to change the incentives. For example, journals should require data transparency for articles they publish, and government agencies should also require it for any study they fund. In addition, they note, the scientific community needs to develop systems to reward researchers for releasing data. One way to reward those who release data involves creating systems to credit the researchers who release data. When others use the data and cite it, the researchers who generated it gain stature and credibility within their fields. One example is the creation of Scientific Data, an entire publication—launched by Nature Research in 2014—focused on publishing data sets to reward those who share that data.

The Charlottesville-based Center for Open Science (COS), led by Nosek, is also taking a lead by creating open science guidelines and systems to reward researchers who follow them. “Our mission is to increase openness, integrity, and reproducibility of research,” COS explains on its website. “We envision a future scholarly community in which the process, content, and outcomes of research are openly accessible by default.” 

Some COS initiatives include:

  • Registered Reports. This program promotes a process that journals can use to essentially peer review a study design before data is collected. COS explains that registered reports “emphasize the importance of the research question and the quality of the methodology by conducting peer review prior to data collection. High-quality protocols are then provisionally accepted for publication if the authors follow through with the registered methodology.” The Open Science website says that 108 journals apply this approach.
  • Transparency and Openness Promotion (TOP) Guidelines. TOP guidelines “require open data, research materials, and analytic code, while encouraging disclosure of additional steps that can increase the credibility of inferential research.”
  • Preregistration of Research Plans. This program encourages researchers to preregister their research plan with COS before beginning to collect data. This approach reduces risk that researchers might “work” data to get positive results. Instead, COS notes, “you’re simply committing to your plan in advance.”
  • Badges. Under this program, journals can award COS-designed badges to researchers who follow certain transparency protocols. When a researcher follows specified transparency guidelines, a badge appears along with his or her article. These badges add credibility to a researcher’s published works, providing a strong incentive for researchers to follow standards for open science.

Yet, challenges remain, including concerns about the privacy of human research subjects. The TOP guidelines, for example, state:

In rare cases, despite authors’ best efforts, some or all data or materials cannot be shared for legal or ethical reasons. In such cases, authors must inform the editors at the time of submission. This will be taken into account during the review process. Authors are encouraged to anticipate data and material sharing at the beginning of their projects to provide for these circumstances. It is understood that in some cases access will be provided under restrictions to protect confidential or proprietary information.

The TOP guidelines highlight that exceptions to data release may be necessary, but only in “rare cases.” Such exceptions are not the rule or the goal. In fact, in the interest of making research more valuable, transparency guidelines will facilitate ways to release data as much as possible. Planning ahead—before collecting data and finalizing study design—should help researchers collect and code data in ways that protect privacy and allow legal release of data sets once they are complete. As COS notes on its website: “Requiring more transparent research practices, with reasonable exceptions for difficult situations, is possible.”

Facts and Misperceptions about the Transparency Rule. Robert Hahn, visiting professor at Oxford University and senior fellow at the Brookings Institution, addressed criticisms of the rule in a Washington Post op-ed appropriately titled, “Many mocked this Scott Pruitt proposal. They should have read it first.” First, he detailed why the rule is needed:

Taking steps to increase access to data, with strong privacy protections, is how society will continue to make scientific and economic progress and ensure that evidence in rule-making is sound. The EPA’s proposed rule follows principles laid out in 2017 by the bipartisan Commission on Evidence-Based Policymaking—humility, transparency, privacy, capacity and rigor—and moves us toward providing greater access to scientific data while protecting individual privacy.

Hahn had served on the U.S. Commission on Evidence-Based Policymaking, which was formed pursuant to the Evidence-Based Policymaking Commission Act of 2016. Sponsored by Rep. Paul Ryan (R-Wisc.) and signed by President Barack Obama on March 30, 2016, it set up a bipartisan commission of 15 experts “to study and develop a strategy for strengthening government’s evidence-building and policymaking efforts,” and produce a report within 18 months. Published in September 2017, the commission report addresses privacy issues, finding that transparency of data can be achieved without compromising privacy concerns:

Traditionally, increasing access to confidential data presumed significantly increasing privacy risk. The Commission rejects that idea. The Commission believes there are steps that can be taken to improve data security and privacy protections beyond what exists today, while increasing the production of evidence. Modern technology and statistical methods, combined with transparency and a strong legal framework, create the opportunity to use data for evidence building in ways that were not possible in the past.

The commission report provides detailed recommendations on how such data can be collected and managed to ensure privacy and transparency. Such efforts can inform regulators as they move forward with implementing the EPA’s transparency rule, which complements similar initiatives already underway in the private sector. Private researchers who want their research to inform regulators should follow such transparency guidelines as well.

Unfortunately, some researchers and transparency advocates seem to misunderstand how the rule would work. For example, Ioannidis says: “A new standard currently proposed for the Environmental Protection Agency aims to ban the use of scientific studies for regulatory purposes unless all their raw data are widely available in public and can be reproduced. If the proposed rule is approved, science will be practically eliminated from all decision-making processes. Regulation would then depend uniquely on opinion and whim.” And even Nosek appears critical of the transparency rule, recently tweeting a Washington Post article critical of the rule, with the comment: “WaPo: ‘Thanks a lot, Scott Pruitt. You’ve made transparency a bad word.’”

Hahn articulately addresses such criticisms in his Washington Post op-ed:

Here’s what the rule would actually do. First, it would require the EPA to identify studies that are used in making regulatory decisions. Second, it would encourage studies to be made publicly available “to the extent practicable.” Third, it would define “publicly available” by listing examples of information that could be used for validation, such as underlying data, models, computer code, and protocols. Fourth, the proposal recognizes not all data can be openly accessible in the public domain and that restricted access to some data may be necessary. Fifth, it would direct the EPA to work with third parties, including universities and private firms, to make information available to the extent reasonable. Sixth, it would encourage the use of efforts to de-identify data sets to create public-use data files that would simultaneously help protect privacy and promote transparency. Seventh, the proposal outlines an exemption process when compliance is “impracticable.” Finally, it would direct the EPA to clearly state and document assumptions made in regulatory analyses.

Here’s what the EPA’s rule wouldn’t do: nullify existing environmental regulations, disregard existing research, violate confidentiality protections, jeopardize privacy or undermine the peer-review process.

Advocates for transparency in science should applaud the EPA’s proposed rule. While much of the work can and should be done in the private sphere, government policy can provide better incentives to researchers on whose work they rely. Ironically, in the same article where he claims the transparency rule would “ban science,” Ioannidis makes some good points that actually support the need for the proposed transparency rule. He notes: 

In the USA and elsewhere, governments are major funders of research and their regulatory mandates provide powerful incentives for best science. Making widely applicable, reproducible research practices and sharing the default option for research (with sparse exceptions, when appropriately justified) will strengthen scientific investigation and maximize its benefits to society at large. Governments can bolster their legacy through such initiatives and scientists would be broadly supportive of such a transformative vision to promote a standard of openness in science.

Efforts to Undermine Transparency. Many critics of EPA’s transparency rule claim it is “anti-science” and represents an ideological attack on regulation. It is true that those who prefer less regulation hope that the rule would eliminate unnecessary regulations that are based on poor-quality science. And it is also true that many oppose the rule because they fear it will weaken regulation. But irrespective of these ideological views, increasing transparency in science, whether used for government regulation or not, is an inherently pro-science goal.

Consider a key argument against the transparency rule, as reported in a May 1, 2018 Science magazine news story, with the headline, “Critics allege EPA’s new transparency rule has hidden pro-industry agenda.” According to these critics, the rule is designed to undermine clean air regulations related to airborne particles smaller than 2.5 micrometers in diameter, known as PM2.5. One key study with unavailable data is the Harvard University Six Cities Study, which the EPA uses to justify very stringent air quality regulations. This 1993 study is a statistical analysis that reported an association between the life spans of people in six cities and the levels of PM2.5 found in the air. It claims that people who live in cities with higher PM2.5 have a life expectancy that is two to three years shorter than those in cities with lower PM2.5 levels.

Harvard researchers maintain that the study participants—whose medical information is part of that data—never agreed for their information to be released. And some critics say it is too difficult, if not impossible, to release the data and keep the subjects’ identities completely anonymous. Whether that is a legitimate concern remains to be seen, but it is not a good argument against the transparency rule. 

Privacy concerns might be a legitimate challenge for releasing some or all of the Six Cities data. If that is the case, the rule, as noted, provides exemptions for rare cases where data cannot be made anonymous and privacy must be maintained. Accordingly, regulators can still use the Six Cities data, if legitimate privacy concerns prevent full release.

In cases where the data can be made anonymous, it should be released regardless of whether it supports weakening or strengthening regulations. After all, if a study’s findings are valid, releasing the data will only strengthen claims about the benefits of these regulations. If the findings are not valid, then we know that regulatory costs may not be justified and that society actually suffers net negative effects because of those costs. Indeed, regulation can translate into higher prices for food, transportation, consumer products, and even medicines. The debate over the rule is not about whether it benefits industry or not, but about how it impacts public health and well-being overall.

According to the most recent Office of Management and Budget (OMB) report on the cost of federal regulations, EPA rules are the most expensive in the federal government. OMB explains “the large estimated benefits of EPA rules” emanate from the EPA air quality program and are “mostly attributable to” reductions in PM2.5. In the interest of public health and well-being, policy makers have an obligation to do their best to ensure that the science actually demonstrates those benefits; data access and replication are the gold standards to ensure it does.

Activists have also cited costs imposed on industries it seeks to regulate. For example, the Union of Concerned Scientists recently released EPA internal emails, obtained via a Freedom of Information Act request, that some say indicate the rule will harm businesses. Yet the only supposed evidence they show is that EPA Office of Chemical Safety and Pollution Prevention Deputy Administrator Nancy Beck had indicated via email that she was concerned about costs to industry and potential challenges with the pesticide and chemical approval processes. It appears that Beck simply recommended revisions to a draft version to address such potential concerns. Certainly, it is reasonable to avoid unnecessary barriers to innovation, but transparency should not be sacrificed because it is inconvenient.

Another criticism comes from a staff writer for The Atlantic, who warns that the costs associated with compliance are simply too high, pointing to a Congressional Budget Office report that said implementing the HONEST Act would cost $250 million a year, as the EPA would have to devote staff to removing confidential information from data. Even if true, this is a relatively modest amount for the agency, given that EPA regulations cost around $394 billion a year, according to estimates developed by Clyde Wayne Crews of the Competitive Enterprise Institute. Moreover, the EPA has plenty of funds within its $8 billion budget to pay for transparency. Heritage Foundation analyst Diane Katz suggests a number of programs that could easily be cut to save the agency billions of dollars a year. In the end, transparency might reduce costs for businesses and consumers, who ultimately pay the high costs of misguided regulations.

Apparently, many of these criticisms are based on misunderstandings about how the rule would work and what it contains. Much of the hype is from those who fear that transparency will weaken regulations, but whether it makes regulations more extensive or scales them back is not the point. The goal is to ensure that the best science informs regulators so that they can design rules to best protect public health. Promoting the fundamentals of good science—transparency and reproducibility—will help achieve that goal.

Conclusion. The EPA rule on transparency should be viewed as yet another tool in a larger effort to promote transparency and reproducibility within the scientific community, most of which is happening outside of government. Ultimately, the value and credibility of scientific research rests on the community’s ability to rein in questionable practices that undermine the scientific discovery process. Much work remains to be done, because the problem spans a wide range of scientific disciplines.

The EPA’s transparency rule will help bolster private pro-transparency efforts and should be the beginning of a government-wide effort. Transparency guidelines could also be applied to government research and government-funded research within all agencies, from the EPA to the National Institutes of Health, the Food and Drug Administration, and the Consumer Product Safety Commission.

Arguments against the rule that claim that it constitutes an assault on science, would violate privacy, or would prevent useful research from informing regulators are without merit. The rule simply supports fundamental principles of scientific research. It contains provisions to protect privacy and provide exceptions that allow regulators to consider quality research that is not fully transparent because of privacy concerns. It will help ensure that regulators are informed by the best science so they can design rules that protect public health while not imposing counter-productive burdens on society.
