New Policies Could Force Increased OMB Oversight Of EPA Risk
Studies
A new memorandum from the White House
Office of Management & Budget (OMB) on federal risk assessment principles
appears to give OMB first-time authority to review “influential” EPA risk
assessments, a move that increases the office's power to review agency documents
and will likely prompt increased Democratic and activist criticisms.
The new principles could also shine a
spotlight on a long-awaited EPA risk review framework that gives OMB the central
role in conducting interagency reviews of agency risk assessments. The framework
has been stalled at EPA for months, and the Government Accountability Office
(GAO) is slated to question federal officials in the coming weeks on the
delay.
OMB officials Sept. 19 unveiled
the memorandum
as a scaled-back, and less formal, version of a controversial draft risk
assessment bulletin that drew significant criticism from the National Academy of
Sciences (NAS), EPA officials, congressional Democrats and others. After NAS
called for OMB to withdraw the bulletin in a January 2007 report, then-OMB
Director Rob Portman said the office would withdraw it “in its current
form.”
The new memo generally reiterates
Clinton-era risk assessment principles that require use of best available
science, qualitative and quantitative risk characterizations, detailed
assumptions and discussion of all relevant hazards. Like the earlier version,
the new document urges agencies to take cost-benefit considerations into account
when making risk management decisions and details a separate set of principles
for priority-setting using risk principles.
However, the memo also now indicates
that oversight of “influential” risk analyses should now fall to OMB, saying
agencies should refer to OMB’s recent bulletin on “good guidance practices” when
deciding on “best practices for . . . influential scientific information.” The
guidance bulletin cites Executive Order 13422, which gives OMB authority to
review agency guidances with an expected economic impact of at least $100
million, as the basis for its expanded review authority of agency documents.
The new memo defines “influential”
analysis as one for which “the agency can reasonably determine that
dissemination of the information will have or does have a clear and substantial
impact on important public policies or important private sector
decisions.”
Giving OMB review authority on the basis
of dividing assessments between influential and non-influential documents
contradicts NAS and senatorial criticism of the White House's now-defunct
proposed bulletin. NAS, for example, said the bulletin's “categories of risk
assessments, and thus the standards, are not based on inherent properties of
risk assessments but on aspects of risk management,” rejecting that approach as
“problematic.”
For instance, NAS said “the effort to
separate risk assessments arbitrarily into two broad categories does not
appropriately recognize the continuum of risk assessment efforts in terms of
potential impact on economic, environmental, cultural, and social values. Any
attempt to divide that continuum into two categories is unlikely to succeed and
will not substantially improve the quality of risk assessments.”
Sens. Joe Lieberman (I-CT), who chairs
the Senate government affairs committee, and Jeff Bingaman (D-NM), who chairs
the energy committee, raised similar concerns in a May 14 letter to
OMB.
A Bingaman spokeswoman now says the
administration has made some improvements in the document but may not have
adequately addressed all concerns. “It's better, but we're not sure if it's as
good as it could be,” the spokeswoman says, noting staff had not fully reviewed
the memo at press time.
OMB first issued its draft bulletin in
January 2006. However, NAS faulted its overly broad definition of risk
assessment, its prescriptive requirements and its adoption of approaches “in
conflict with long-established concepts and practices.” NAS also objected to the
proposed bulletin's definition of “adverse health effect,” which it found to be
too limiting for the purposes of risk assessment and mitigation. The definition
“ignores a fundamental public health goal to control exposures well before they
cause functional impairment,” the committee said.
The new risk memorandum, signed by OMB
Office of Information & Regulatory Affairs Administrator Susan Dudley and
White House Office of Science & Technology Policy official Sharon Hays, says
OMB decided “not to issue the [risk] bulletin in final form. Rather, we are
issuing this Memorandum to reinforce generally-accepted principles for risk
analysis upon which a wide consensus now exists.”
The memo acknowledges that environmental
and health analyses are its primary targets, saying in a footnote, “While many
of the principles presented in this Memorandum may be relevant to other fields .
. . the focus of this Memorandum is on those risk analyses related to
environmental, health and safety risks.”
That acknowledgment mirrors activist
concerns that the proposed bulletin, while applying to the entire federal
government, would have most strongly influenced EPA decision-making because of
the nature and scope of the agency's research and analysis
programs.
While the decision to release the memo
rather than finalize the bulletin may satisfy some skeptics because it is less
prescriptive than the proposed bulletin, allowing EPA to keep some flexibility
when conducting risk assessments, it has prompted criticism from activists who
say it continues to subordinate scientific rigor to cost-benefit analysis, which
has become a cornerstone of the White House's risk assessment and regulatory
approach.
The new memo directs risk managers
charged with making policy decisions to OMB Circular A-4, which lays out how to
conduct regulatory cost-benefit analysis. “Agencies should employ the best
available scientific, economic and policy analysis, and such analyses should
include explanations of significant assumptions, uncertainties, and methods of
data development,” the memo says.
The memo adds, “In making significant
risk management decisions, agencies should analyze the distribution of the risks
and the benefits and costs (both direct and indirect, both quantifiable and
non-quantifiable) associated with the selection or implementation of risk
management strategies.”
The memo also strongly supports the
highlighting of uncertainty in risk assessments, a priority of EPA Office of
Research & Development Assistant Administrator George Gray. Echoing Gray's
frequently stated position, the memo says, “Due to the inherent uncertainties
associated with estimates of risk, presentation of a single estimate may be
misleading and provide a false sense of precision. Expert panels agree that when
a quantitative characterization of risk is provided, a range of plausible risk
estimates should be provided.”
That approach to risk assessment has
drawn fire from several quarters, including from site cleanup managers who argue
a range of risk estimates cannot easily be extrapolated into a health or cleanup
standard.
The new memo is similar in some respects
to a version proposed by the industry-funded Center for Regulatory Effectiveness
(CRE), which was floated earlier this year “to focus peoples’ attention and get
the ball rolling,” a CRE source said at the time. For instance, the memo
highlights the role of the CRE-backed Information Quality Act (IQA) in future
risk assessment procedures, saying in a footnote that the entire memo “is
intended to complement and support” OMB implementation guidelines for the
law.
A CRE source now agrees that the new
memo means “all [OMB] regulations and procedures are now applicable to risk
assessment,” specifically noting its “incorporation by reference” of IQA
guidelines. The source also highlights the memo's “strong statement that they'll
follow up on how agencies comply. If they do that, it's a pretty significant
change.”
The source declined to discuss
parallels between the memo and CRE's draft, saying, “I don't want to go into
that. Ask other people.” -- Adam Sarvana
