Hazard Ranking System (HRS) is a 4-day training course designed for personnel who are required to compile, draft and review preliminary assessments (PA), site inspections (SI), and HRS documentation records and packages submitted for sites proposed for the National Priorities List (NPL). This course is open to EPA, federal, state, tribal and contractor personnel who support site investigation programs.
The HRS course provides a detailed review of the HRS model and how the model is applied to various site conditions. The course is intended to enable staff to prepare HRS packages for the National Priorities List (NPL) and to plan and implement preliminary assessments (PA) and site inspections (SI) to address future HRS scoring issues. By taking the course, participants will achieve the following objectives:
Explain the site assessment process under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the role of HRS. The course provides an overview of key provisions of CERCLA and the general response process established under the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The course discusses procedures and requirements for conducting site assessments and using the HRS to score sites for placement on the NPL.
Define and explain the HRS in detail. The course explains the overall structure and elements of the HRS and how a site score is calculated. The course also provides a detailed explanation of each scoring factor (likelihood of release, waste characterization and targets) for each pathway (groundwater, surface water, soil exposure and air) evaluated by the HRS. In addition, the course addresses HRS rules for scoring sites with releases of radionuclides.
Illustrate a general approach to scoring sites using the HRS and preparing an HRS package. The course provides an introduction to the process by which HRS packages are prepared, identifies the elements of a complete package and discusses accurate site scoring. The course examines documentation and analytical data quality needed to support HRS packages.
Identify and use guidance and software to successfully prepare an HRS package. The course will identify regulations and guidance issued by the EPA applicable to HRS scoring packages and has participants prepare an HRS score for a site.
