Circumstances of Change Request for OMB #0923-0044

This is a nonmaterial/non-substantive change request for OMB protocol #0923-0044 (expiration date: October 31, 2015). OMB approval was granted for data collection for a cooperative agreement program involving three state health departments (Michigan Department of Community Health, New York State Department of Health and Minnesota Department of Health).

We are requesting to change the proportion of study participants (shoreline anglers) attributed to each of two Michigan areas. In the original sampling frame, a target sample size of 200 people from the Detroit River area and 200 people from the Saginaw River/Bay area was planned. During the course of screening, high water levels in the Saginaw River flooded the study site and thus prevented shoreline fishing. Therefore, we anticipate that study participants will include 50 people from Saginaw River/Bay area and 350 people from the Detroit River area. The target total number of urban anglers remains 400.

Attached please find revised Supporting Statement A which incorporates the change in requested burden costs and revised Supporting Statement B. The total estimated annualized burden cost is increased slightly due to the higher estimated wage and the higher proportion of urban anglers in the Detroit Metropolitan Statistical Area.

The overall number of respondents and requested burden hours from Michigan remains the same. The aim was to estimate only pooled statistics combining results from both areas. As such, we would appreciate your expedited consideration of this request.
