OMB approves the
requested survey for purposes of exploratory research, consistent
with the limitations of the proposed experimental design. These
limitations include lack of blood sampling from controls for
purposes of comparison, reliance on a self-selected sample, lack of
a systematic approach to site selection and insufficient
information for determining study power. As such, OMB does not
approve the collection for purposes of developing public health
standards for microcystin levels, for assessing health risks
associated with microcystin exposures, or for providing
gerneralizable or representative data with respect to the effects
of microcystins on humans. Rather, this project may provide the
basis for developing more refined designs for future research.

The purpose of this data collection is
to assess human exposure to microcystins in recreational waters.
The study will focus on verifying exposure, collecting symptom
data, and assessing microcystins in serum. The results from this
study will be useful to health agencies in states whre seasonal or
year-round blue-green algae blooms occur. The methods for data
colletion include environmental sampling, questionnaires, and blood
sampling.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
