A. JUSTIFICATION
A.1. Circumstances Making the Collection of Information Necessary
The National Institute of Environmental Health Sciences (NIEHS) is responsible for conducting
research on chemical, physical, and biological factors in the environment that affect human health. The
GuLF Study, with its focus on potential short- and long-term health effects associated with oil spill
clean-up activities and exposures surrounding the Deepwater Horizon disaster, is supported by the
mandate of NIEHS as defined by US Code Title 42, Chapter 6A, Subchapter III, Part A, Section 281, as
amended by the Health Research Extension Act of 1985, which is “the conduct and support of research,
training, health information dissemination, and other programs with respect to factors in the environment
that affect human health, directly or indirectly.”
There has been little research on the long-term health effects from oil spills despite the fact that
between 1970 and 2009, there were 356 spills of more than 700 tons from oil tankers, with approximately
38 of these spills affecting coastal populations [International Tanker Owners Pollution Federation Limited
(ITOPF) 2009, Aguilera, et al. 2010]. The Deepwater Horizon disaster, with its release of approximately 5
million barrels (~680,000 tons) of crude oil into the Gulf of Mexico, is far larger than any of these tanker
spills. Given the magnitude of this spill and the scope of the potential exposures – at least 55,000 workers
involved in clean-up efforts and countless residents of the affected areas – study of the human health
effects of this spill is urgently needed to monitor Gulf clean-up workers and to understand the adverse
consequences of oil spills in general.
This research effort is designed to investigate potential short- and long-term health effects among
workers engaged in clean-up activities surrounding the Deepwater Horizon oil spill. Given the very
limited health effects research conducted to date on oil spill clean-up workers, the GuLF Study is
designed not to study a few narrow a priori hypotheses, but rather to allow the investigation of a wide
range of potential adverse health effects, including physical, psychological, and biological effects. The
long-term goal of this study is not only to identify adverse health outcomes related to clean-up activities

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 4 of 18

among the Deepwater Horizon responders, but also to assemble information that can be used for
prevention and intervention of adverse health outcomes in any future similar disasters.
The over-arching hypotheses of this study are:
1. Exposure to constituents of oil, dispersants, and oil-dispersant mixtures, and to spill-related stress
by workers engaged in clean-up of the Deepwater Horizon oil spill are associated with adverse
health effects, particularly respiratory, neurological, hematologic, and psychological or mental
health.
2. There are exposure-response relationships between the above exposures and health effects.
3. Biomarkers of potentially adverse biologic effects are associated with the above exposures.

A.2. Purpose and Use of the Information
Information collected in this study will be used to further scientific understanding of the shortand long-term health effects associated with oil spill clean-up activities and exposures to a range of
known and suspected toxins in crude oil, burning oil, and dispersants, to excessive heat, and possibly to
stress due to widespread economic and lifestyle disruption. Epidemiologists and biostatisticians at NIEHS
and their collaborators at other institutions will be responsible for testing the hypotheses of interest and
disseminating results through the scientific literature. Results will be published in medical and
epidemiologic journals as well as basic science journals when appropriate. Results will be presented at
scientific meetings and to other interested groups. Given the very limited health effects research
conducted to date on oil spill clean-up workers, the GuLF Study is designed not to study a few narrow a
priori hypotheses, but rather to allow the investigation of a wide range of potential adverse health effects,
including physical, psychological, and biological effects. The long-term goal of this study is not only to
identify adverse health outcomes related to clean-up activities among the Deepwater Horizon responders,
but also to assemble information that can be used for prevention and intervention of adverse health
outcomes in any future similar disasters.

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 5 of 18

The purpose of the GuLF Study is to investigate potential short- and long-term health effects
associated with oil spill clean-up activities and exposures surrounding the Deepwater Horizon disaster;
and to create a resource for additional collaborative research on focused hypotheses or subgroups. Over
55,000 persons participating in oil-spill clean-up activities have been exposed to a range of known and
suspected toxins in crude oil, burning oil, and dispersants, to excessive heat, and possibly to stress due to
widespread economic and lifestyle disruption. The purposes for collecting data on stress exposures of oilspill workers is to explore how stress may affect health outcomes and biomarkers for health outcomes.
Additionally, we have an opportunity to contribute information to the topic of mental health aspects of the
oil spill environmental disaster although we recognize that because this is a secondary aim of the study,
we have not designed a definitive study of the impact of the spill on mental health.
Exposures range from negligible to potentially significant, however, potential long-term human health
consequences are largely unknown due to insufficient research in this area. A cohort of 55,000
participants will be recruited from across job/exposure groups of primarily English, Spanish, or
Vietnamese speaking adults (accommodations for other languages developed as appropriate) who
performed oil-spill clean-up-related work (“exposed”) and similar persons who did not (“unexposed”
controls), and followed in either an Active Follow-up Sub-Cohort (N~24,000) or a Passive Follow-up
Sub-Cohort (N~31,000). Exposures will be estimated using detailed job-exposure matrices developed
from data from monitoring performed by different agencies and organizations during the crisis,
information obtained by interview, and the available scientific literature. We will investigate acute health
effects among all cohort members via self-report from the enrollment interview, and via clinical measures
and biological samples from Active Follow-up Cohort members only. All cohort members will be
followed for development of a range of health outcomes through record linkage (e.g., cancer, mortality)
and possibly through linkage with routinely collected health surveillance data (collected by health
departments and the CDC) or with electronic medical records. Recruitment of subjects should begin in
early 2011, with telephone interviews and the baseline home visits conducted within 24 months.

GuLF Study—OMB 2010: Supporting Statement A REVISED

[A Biomedical Surveillance Sub-cohort (N~5,000) will be nested within the Active Follow-up
Cohort, and will participate in clinical assessment after an initial home visit, including pulmonary
function testing, neurological testing, and collection of additional biological and environmental samples.
Periodic follow-up of the Biomedical Surveillance Sub-cohort will include clinical evaluations (e.g.,
spirometry, neurological testing) and collection and analysis of additional biospecimens (e.g.,
immunologic parameters, liver function, renal function, DNA damage). Clinical protocols for the
Biomedical Surveillance Sub-cohort will be developed and carried out in collaboration with local
university partners identified through a request for proposals (RFP). Clinical Exemption will be sought
separately for the Biomedical Surveillance sub-cohort.]
The type and amount of information we will collect at baseline and at subsequent intervals fulfill
many scientific and clinical needs. Many of the exposures of interest, including endogenous hormone
levels, micronutrients, and some environmental exposures, are measured most accurately in biological
samples collected before the onset of disease or treatment and their associated symptoms and biological
and lifestyle changes. The cohort design allows us to collect data on exposures, including biological
exposure measures, diet and lifestyle, before the onset of disease. Instruments for baseline data collection
activities are appended (Appendices I & J).
Brief self-administered forms will be used annually to update changes in contact information.
Biennial updates will record changes in health, lifestyle, occupational and environmental exposures
within the Active Follow-up sub-group (~24,000 participants).
Clinical exemption will be sought separately for more extensive testing and long-term follow-up
of a small group (5000 of the Active sub-group) who will comprise a Biomedical Surveillance Subcohort.

A.3. Use of Information Technology and Burden Reduction
Computer Assisted Telephone Interview, or CATI, a special data collection approach designed to
reduce the burden to respondents and improve quality control, will be used for the initial eligibility

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 7 of 18

questionnaire (administered to all respondents), enrollment questionnaire (administered to all enrolled
participants), and biennial questionnaire (administered to Active sub-group). This technology allows
several advantages over the traditional pencil and paper method. First, it requires less paper. Second, there
is no “mail wait” to get the information from participants. Also, the telephone interview requires little
reading for the participants, an important factor when a segment of the population has low educational
level or poor eyesight. Last, data extraction is more efficient with the CATI system as compared to the
keyed entry method because skip patterns are automated and response inconsistencies can be queried at
the time of the interview. Web-based questionnaire options will be explored as needed to increase
response rates.
Name, address, SSN, date of birth, and medical information will be collected. Personal identifiers
will be stored encrypted and separately from all other data. PII will be used to address Update materials.
A Privacy Impact Assessment will be completed for the information management system.

A.4. Efforts to Identify Duplication and Use of Similar Information
The information we will collect is not available from other sources. There has been little research
of the long-term health effects from oil spills. The few studies that have evaluated the human health
consequences of oil spills have primarily focused on acute physical effects and psychological sequelae.
These studies have examined the Exxon Valdez (Alaska, 1989), Braer (Shetland Islands, UK, 1993), Sea
Empress (Wales, UK, 1996), Nakhodka (Oki Islands, Japan, 1997), Erika (Brittany, France, 1999),
Prestige (Galicia, Spain, 2002) and Tasman Spirit (Karachi, Pakistan, 2003) oil tanker spills. Most of
these studies were cross-sectional and limited in breadth. Appendix A contains the full list of references
reviewed. We are unaware of any duplication of this project with any other project now underway at
other organizations.

A.5. Impact on Small Businesses or Other Small Entities
No small businesses will be involved in this study.

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 8 of 18

A.6. Consequences of Collecting the Information Less Frequently
Annual updates take ~15 minutes, and biennial questionnaires will be ~30 minutes. Annual contact is
necessary to preserve reliability and completeness and will facilitate maintenance of the cohort and
tracing of those who are lost to follow-up. Biennial contact cannot be done less frequently because the
analysis relies on exposure and health-status changes over time, and ascertaining cases close to the time
of diagnosis is important. A participant’s recall diminishes greatly with time, and death may occur.

A.7. Special Circumstances Relating to the Guidelines of 5 CFR 1320.5
There are no special circumstances relating to the guidelines of 5 CFR 1320.5 and the project fully
complies.

A.8. Comments in Response to the Federal Register Notice and Efforts to Consult Outside Agency
A 60-Day Federal Register Notice was published 7 October 2010 on pages 62132-3. One public
comment suggested that since BP was supposed to pay for medical costs associated with the spill, that
service records billed to BP should contain all information necessary for the study, and thus no survey is
needed at the public’s expense.
Agency Response: BP covered the medical costs of workers who required care while they are
engaged in clean-up efforts. There are no provisions for BP coverage for short-term medical care needed
when workers have completed their service. Thus focusing only on medical records will potentially
seriously underestimate the extent of illness linked to the oil spill and will not assess any latency or
persistence of effects. There is no systematic assessment of health care needs or disease incidence.
Focusing only on those who sought care at the time they were working can lead to serious bias – either
underestimating illnesses because workers may have been afraid of retribution or job loss if they reported
a problem, or over-reporting because clinics provided free care during work and did not require the
symptoms or conditions to be oil-spill related. BP is contributing to the cost of this research. They made
$10M available to NIH via a gift for health research. About $6M will go toward this study. The door is

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 9 of 18

still open to other gifts from BP in future years. The DHHS is carefully tracking costs associated with
health care research including the GuLF Study so that they will be in a position to seek reimbursement
from BP from any funds made available in the future either voluntarily or as a result of governmental or
legal actions.
The GuLF Study is an NIEHS intramural study designed to allow for trans-NIH and extramural
collaboration. A GuLF Study Scientific Advisory Board will be established as a subcommittee of the
NIEHS Board of Scientific Counselors to provide additional oversight. This Board will include one or
more members of the Board of Scientific Counselors, scientific experts, community representatives and
Federal agency representatives. A separate Community Advisory Board, consisting of representatives of
key study populations in the affected states, also will be established. The Institute of Medicine has
reviewed the initial study plans, and periodically will review progress and findings. An Interagency
working group made up of representatives from each Federal Agency involved in some aspect of the oil
spill response met in August 2010, and is expected to meet regularly to provide study oversight. In
addition we have established contacts with community organizations, representative worker
organizations, advocacy groups, and state and local governments to identify the primary health issues of
concern locally and to discuss study implementation issues across the five state area. Further, we will
identify Community Outreach Coordinators to organize and implement outreach activities in each of the
Gulf States. In addition to the continuing efforts with public health and community group representatives,
we have been conducting and will continue webinars, dockside chats, and phone and in-person briefings
with key stakeholder groups and health departments. These activities are itemized in detail in section
2.4 of the attached study protocol (Attachment 1).
Potential participants will be identified via tremendous cooperation among organizations and
agencies providing access to relevant worker databases: the NIOSH Voluntary Worker Roster, Petroleum
Education Council (PEC; access provided by BP), and we will seek a similar agreement to obtain other
known lists of individuals involved in clean-up activities (e.g., parish responder lists, BP contractor
payroll, and lists of Federal workers and contractors deployed to, or otherwise engaged in, on-site clean-

up activities in, the Gulf, including the Coast Guard, OSHA, NIOSH, NOAA, EPA, Fish and Wildlife
Service, US Geologic Survey, National Guard, etc.). We will work closely with academic and federal
partners such as OSHA and NIOSH to convene a panel of experts to systematically work through
exposure assessment issues and develop a scientifically sound method for assigning exposures to the
study participants.
Advisory to the study principal and lead investigators in regular monthly meetings are the study
team, all of whom will contribute to study oversight, and have the experience necessary to provide this

A.9. Explanation of Any Payment or Gift to Respondents
In addition to non-monetary incentives such as refrigerator magnets, chip clips, stationery, and pens,
participants in the Active Follow-up Sub-cohort will receive remuneration for their time and effort in the
form of pre-paid gift cards or phone cards. A monetary incentive will be offered to participants at the
baseline home visit. Gift cards with a $50 value will be given to participants immediately upon
completion. Participants will be asked to acknowledge their receipt of their gift card by completing a form
(Appendix V), which will be returned by the HVA to the study office with other study materials. If the
Participant also provided an additional Quality Control Sample for the study, they will be given an
additional $10 gift card, receipt of which will also be acknowledged on this form.

Additional incentives for recruitment and participation such as drawings for prizes such as
sporting event tickets, and recruitment events featuring food bank distributions, community health fairs,
or other community events will be explored based on feedback from the community and assessment
during the run-in phase of the study. We will confer with the appropriate scientific, community,
institutional and ethical advisory boards to determine the appropriateness of these additional incentives.

A.10. Assurance of Confidentiality Provided to Respondents
Procedures to protect the confidentiality of the study population and the data collected include the
following:
•

The data constitute a system of records under the Privacy Act System (#09-25-0134; Federal
Register Notice of System of Recordsm published December 29, 1993.

•

All study personnel will be required to complete on-line training in the protection of human
research subjects. The investigators and study staff will strictly maintain participant
confidentiality to the extent permitted by law. This confidentiality will be extended to cover
questionnaire data, clinical assessments, biological samples, and environmental samples.

•

All study-related information will be stored securely. All study datasets, laboratory specimens,
and administrative forms will be identified by a coded number in order to maintain participant
confidentiality. All records that contain names or other personal identifiers will be stored

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 12 of 18

separately from study records identified by code number. All databases will be secured behind
firewalls with password-protected access systems. Worksheets, lists, logbooks, appointment
books, and any other documents that link participant ID numbers to other identifying information
will be stored in a separate, locked file in an area with limited access.
•

A Federal Certificate of Confidentiality will be obtained for this study. The Certificate will help
protect against disclosures of study-related information by Federal, State or local civil, criminal,
administrative, legislative, or other proceedings, although it will not guarantee that data cannot be
released. Participants will be informed about the certificate during the informed consent process.

•

The proposal was initially reviewed by the Institutional Review Board of NIEHS on 11/09/2010
and approved after revisions in response to stipulations.

•

Informed consent forms spells out the steps taken to protect privacy. Similar information is
provided verbally at the time of enrollment.

•

The GuLF Study will follow NIH policies on data sharing. We will be required to send deidentified datasets to an approved NIH repository such as DbGaP (where data from GWAS
studies and studies like the Framingham Study are now stored) — http://www.ncbi.nlm.nih.gov/gap.
Currently, investigators are required to sign confidentiality agreements and agree to use the data
just for the purposes specified in their request. They must agree to not attempt to contact any
individuals in a study. Security procedures and requirements can be found at —
http://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/GetPdf.cgi?document_name=dbgap_2b_security_procedures.pdf.

An NIH committee reviews the request and assesses the qualifications of the requestor. The goal
is to provide data to as many qualified individuals as possible while attempting to protect
participants from disclosure of identity, and to allow for maximal and rapid use of a government
funded resource. Open access to de-identified data is being driven by the NIH director.
Traditional identifying information will not be shared. This includes name and address, complete
date of birth, social security numbers, and GPS coordinates.

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 13 of 18

•

The biological and environmental samples collected will be stored indefinitely in a secure
building for future testing and may be disposed of at any time at the Investigator’s discretion.
Specimens are labeled with ID number only. Specimens shared with outside researchers— only
with the approval of the IRB— will be assigned a new identification number; the code linking the
new and the old identification number will be known only to the NIEHS contractor responsible
for the GuLF Study field work. This new identification number will not be linked to any
identifying information.

•

Participants may elect to leave the study at any time. As explained in the Informed Consent
documents, no new data will be collected from individuals who elect to drop out, but the data
already provided will continue to be used in some analyses unless a written request to destroy
data and specimens is received. Screening data on respondents who are found to be ineligible
will not be retained.

A.11. Justification for Sensitive Questions
Exposures and health outcomes experienced by oil spill clean-up workers are likely to be
complex. Sensitive questions such as personal and family history of illness and detailed medical history
are critical to study hypotheses. For example, alcohol use, while part of a standard medical history, may
be perceived by some to be too personal, but it must be accounted for in analyses exploring health
outcomes. Some questions, such as about mental health or social support, may be perceived as especially
sensitive, but the study seeks to understand effects that stress exposures during the clean-up work may
have on health. The baseline questionnaire, administered to the Active Follow-up group, elicits
information not included in the enrollment questionnaire, including more detailed information on
residential and occupational history, personal and family medical history, alcohol and tobacco
consumption, mental health and anxiety, and recent eating and drinking and use of medications.
Information is collected directly from participants. Participation is voluntary, and respondents can
withdraw from the study at any time. Participants may refuse to answer specific individual questions,

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 14 of 18

including those they find to be too sensitive or personal. All information is kept confidential to the extent
provided by law. At no time will any individualized genetic results be given out. A Certificate of
Confidentiality will be sought for this study.

A.12. Estimates of Hour Burden Including Annualized Hourly Costs
Frequency of Response: Participation will include one enrollment telephone interview (0.65 hr);
collection of biological and environmental samples, basic clinical measurements, and GPS coordinates
(2.75 hr) from the Active Follow-up Cohort only; annual contact information update (0.25; Active and
Passive) or biennial follow-up telephone or web interviews (0.5 hr; Active only) for 10 years or more.
We also anticipate shorter eligibility screening times (~13.5 minutes) for ~31,000 ineligible respondents.
Affected Public: Individuals or households. Type of Respondents: Workers involved in Deepwater
Horizon disaster clean-up, and similar individuals not involved in clean-up effort. The annual reporting
burden is as follows: Estimated Number of Respondents: Active Follow-up Cohort (N~24,000) and
Passive Follow-up Cohort (N~31,000). Estimated Number of Responses per Respondent: See table
below. Average Burden Hours Per Response: 0.60 hour; and Estimated Total Burden Hours Requested:
155,975 (over 3 years). The average annual burden hours requested is 51,992. The annualized cost to
respondents is estimated at $12 (assuming $20 hourly wage X 0.60 hour). There are no Capital Costs to
report. There are no Operating or Maintenance Costs to report.

GuLF Study—OMB 2010: Supporting Statement A REVISED

page 17 of 18

Given the very limited health effects research conducted to date on oil spill clean-up workers, the
GuLF Study is designed not around a particular a priori hypothesis, but rather to allow investigation of a
wide range of potential adverse health effects, including physical, psychological, and biological effects.
These include both short-term and long-term effects focused on, but not limited to, the following areas:
respiratory, cardiovascular, hematologic, dermatologic, neurologic, cancer, reproductive, mental health,
immunologic, hepatic, and renal. A priori outcomes of greatest interest based on previous studies are
respiratory effects, neurological dysfunction, and genotoxic and hematologic effects.

A.17. Reason(s) Display of OMB Expiration Date is Inappropriate
None

A.18. Exceptions to Certification for Paperwork Reduction Act Submissions
There are no exceptions to certification for this submission.
