PASI Webinar Series
Hosted by U.S. EPA
Office of Superfund Remediation and Technology Innovation

The CERCLA Education Center (CEC) Preliminary Assessment and Site Inspection (PA/SI) Webinar Series is an intermediate training course designed for personnel who are required to compile, draft and review PA, 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 PA/SI Webinar Series provides an introduction to the Superfund site assessment process and describes the preliminary assessment and site inspection phases of this process. The course will incorporate a mix of lecture and exercises using Quickscore for each of the four pathways. The objective of the exercise is to give participants the opportunity to evaluate and score PA information using the HRS Quickscore software. Participants will use information from a fictitious site to (1) evaluate and calculate a preliminary HRS score, and (2) develop release and target hypotheses that should be pursued in an SI.

PA/SI Module 1: Overview of the Site Assessment Process under CERCLA
This introductory module will provide an overview of key provisions of CERCLA and the response process established by the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). In addition, it will provide an overview of the purpose, scope and requirements for performing a remedial preliminary assessment (PA) and remedial site inspection (SI) at sites regulated by CERCLA.

PA/SI Module 2: Basics of Performing Site Assessments and Conducting the PA
This module will provide an overview of the basics of performing site assessments including the purpose and scope of the different steps in the site assessment process and the roles and responsibilities of the different parties involved. It will identify and explain procedures for performing a remedial PA.

PA/SI Module 3: Site Evaluation and Scoring Site Sources
This module focuses on the specific elements of the scoring process that participants must understand to successfully apply the scoring model to a PA.

In the second half of this module, the instructors will apply the Quickscore software to an example PA. It will review “sources” for the purpose of the HRS. Participants will review appropriate site information and the instructors will lead them through inputting the information into the Quickscore software.

PA/SI Module 6: PA Scoring Exercise: Soil Exposure and Air Migration Pathways
This module will review the soil exposure and the air migration pathways. Participants will review appropriate site information and the instructors will lead them through inputting the information into the Quickscore software.

PA/SI Module 7: Conducting the SI, Overview of SI Strategies, and Site Sources
This module will identify the step-by-step activities for conducting a remedial SI, including discussion of health and safety considerations for field activities, establishing data quality objectives and developing sampling strategies to obtain data for HRS scoring, validating data and preparing a final report to document the decision-making process. It will provide an overview on how to develop SI sampling strategies that consider and address the needs of the HRS. In particular it will review SI sampling strategies for sources as well as general considerations.
