Spring 2020 MWCC Technical Seminar:

Effective Application of Multiple
ITRC Guidance Documents to Hydrocarbon Sites

Monday, May 12, 2020
9:00 am - 4:00 pm

Kauffman Foundation Conference Center
Brush Creek Room, 4801 Rockhill Road

Kansas City, MO 64110


The Missouri Waste Control Coalition is pleased to bring this seminar to Kansas City’s Kauffman Conference Center in Kansas City, MO. This program is presented by nationally recognized state and industry leaders in project management, remediation, geology, and hydrogeology.

Hydrocarbon-impacted sites are subject to regulations and guidance directed at petroleum vapor intrusion, total petroleum hydrocarbons in soil, and LNAPL.  These regulations do not always acknowledge the interrelated nature of these concerns.  ITRC has worked over the past five years to provide guidance related to each concern; however, practical integration of the concepts in each of the three guidance documents is necessary to provide a comprehensive evaluation at most petroleum hydrocarbon sites.

This 6-hour course provides a high-level review of concepts presented in hydrocarbon-related ITRC documents.  The course invites audience participation in navigating case study examples of typical scenarios encountered at hydrocarbon sites addressing:

  • concepts of maximum extent practicable, LNAPL transmissivity, and NSZD to manage TPH risks.
  • risk assessment/management at former hydrocarbon sites undergoing redevelopment/land use change.
  • developing a comprehensive conceptual site model (CSM) to satisfy elements of all three ITRC guidance documents.

Real-world examples will illustrate how two or more of ITRC’s documents overlap in providing guidance and represent actual questions/concerns from regulators and practitioners.  When all three ITRC documents are reviewed together, they can provide a beneficial roadmap to guide practitioners through successful assessment and identifying closure pathways for their own projects.


Registration fee is $60 and includes the seminar, any materials and lunch.
