The Interstate Technology Regulatory Council (ITRC) Unexploded Ordnance (UXO) Team recently released the Munitions Response Historical Record Review. This guide provides a methodology for planning and implementing what should be one of the first steps when initiating a munitions response (MR) program – the historical records review (HRR). Reviewing historical records in an organized, site-tailored approach sets the foundation for later steps, such as investigation and remediation, in the MR process. This manual benefits regulators and stakeholders in many ways. A breakdown of content shows that the document includes guidance for the following areas: - Commonly used terminology - Importance of historical document review - Department of Defense (DOD) MR program outline - HRR team assembly - Stakeholder communication - Project objectives and planning - Site visits - Work plan development - Data source identification, quality, and archival - Site modeling - Data and site research - Analysis and interpretation - Results reporting and review process This guide is meant to serve as an educational tool and as a template that can be customized to fit different regulatory protocols and frameworks. Also, it uses diagrams and tables to present the flow of the MR HRR project phases. (Date Approximate)
