Ecological Risk Assessments (HHRA). Based on the review of the responses and discussions on specific wells to be included in the exposure units, the Division agrees with ATK’s current proposal. It is understood that additional details on the Groundwater HHRA will be provided in the near future in a
work plan to address two of the comments. If you have any questions, please call Jeff Vandel at [phone]. Sincerely,
