First Environment’s own Phillip Ludvigsen, PhD, and Josh Heltzer will be presenting “Reconstruction of Historic Processes: The Key to Quantifying Contaminant Mass Loading from Manufactured Gas Plants and Other Industrial Facilities” at Battelle’s Ninth International Conference on Remediation and Management of Contaminated Sediments taking place January 9-12 in New Orleans.

 

Battelle’s sediments conference series serves as a “forum for sharing research results, practical experiences, and opportunities associated with remediating, restoring, and managing the environmental and economic vitality of waterways. Maintaining the viability of these aquatic systems requires complex actions that affect a diverse group of stakeholders and raise a wide range of environmental, economic, political and social issues.”

 

“Reconstruction of Historic Processes: The Key to Quantifying Contaminant Mass Loading from Manufactured Gas Plants and Other Industrial Facilities”

 

Date and Time:    5:45 – 7:00pm Wednesday, January 11, 2017

Location:               Exhibit Hall

 

Background/Objectives

The operation of Manufactured Gas Plants (MGPs) going back more than 150 years has resulted in numerous and costly site remediations. Much of MGP contaminant mass loading occurred in the earlier part of the 20th century, when records on waste disposal were practically non-existent. This presentation will outline an industrial process-based approach to quantifying the mass loading from MGPs to nearby surface water and river systems. Learning objectives include the following:

 

Approach/ Activities

Our approach consists of combining production data with historic waste to production ratios to calculate levels of waste generation. Waste treatment and subsequent disposal is based on the standard-of-care applied at the time of production. We will demonstrate the ability to support clean-up cost allocations and apportionment of environmental impairment liabilities by applying this approach to remediation sites with data spanning the last 100+ years.

 

Results/Lessons Learned

A critical component of this approach is applying historic forensic analysis to establish waste generation capacity over the life of a given industrial facility. By focusing on available historic information or surrogate indicators as well as historic standard-of-care, we have developed a useful spreadsheet calculation approach to support fair and equitable clean-up cost allocations and apportionment of environmental impairment liabilities.
