Petroleum Tank Cleanup Section


Section Overview


The goal of the Petroleum Tank Cleanup Section is to protect human health and the environment from petroleum and hazardous substance releases from storage tank systems, both underground and above ground. Meeting this goal requires definition of the extent and magnitude of the contamination and implementation of the necessary corrective action. About the Program

The DEQ petroleum Tank Cleanup Section (PTC) and the Petroleum Tank Release Compensation Board (PTRCB) will be hosting an informational meeting next Tuesday, May 23.  In Helena, please join us at the Metcalf Building in Room 111 from 1:30-5:00.  If you are interested in joining via GoTo Meeting, please contact Amber Skillman at 444-6443.  You can go to either of our field offices as well. 

For PTC, the broad discussion topics will be: 

1) Pending PTC business process updates (See note below);

2) Electronic submittals

3) Data validation

4) Reporting releases on time

5) Landfarm review

PTC business process updates: PTC is committed to keeping you informed as we develop our improvement plan to implement some long-discussed business process improvements.  The detail in this email is initially high-level because PTC anticipates identifying more specific changes and seeking your input  over the next several months.   We intend to make our processes more streamlined and effective, and to promote quality and time savings in the spirit of dedicating energy and efforts towards actual boots on the ground remedial activities.  The changes we will propose over the next year will be to improve the corrective action plans and reports.  More specifically, you can expect to have an electronic-only (“paperless”) submittal requirement, as well as a CAP and report format improvements. PTC will also standardize formal CAP and report review process.

Emerging Cleanup Technology (9/14/2016)

Description: Aimed at state and tribal corrective action employees, this webinar will provide participants with information on:

  • High Vacuum Dual Phase Extraction
  • Activated Carbon Injection

Webinar Recording

Webinar Presentations:
High Vacuum Dual Phase Extraction - Noel Shenoi, CalClean, Inc.
Activated Carbon Injection - Tom Fox, CO Division of Oil and Public Safety; Edward Winner, KY UST Branch


Smart Characterization - The New Era of Site Investigations. 


This is a two hour recorded webinar that consists of the following topics: 

  • Smart Characterization and Return on Investigation: Newly developed tools and strategies for mapping source zones and dissolved-phase plumes. Using high-resolution, Smart characterization strategies to reduce total life-cycle costs of restoration by 3x-5x


  • Stratigraphic Flux: A new classification system that enables one to extend sequence stratigraphy to understand transport and restoration potential and improve restoration performance. The approach maps relative mass flux and plume maturity using high-resolution characterization data and classical geology interpretation. 


  • A new approach to NAPL Management: leveraging return-on-investigation and stratigraphic flux approaches to develop digital NAPL CSMs, and determine when to manage and when to remediate NAPL. Topics will include advanced NAPL mapping methods, how to evaluate NAPL mobility and risk, and how inclusion of natural source zone depletion in the NAPL CSM is critical to practical restoration decisions.


The training was led by Arcadis experts in ROI (Return on Investigation) and Smart Characterization:


Nick Welty, director of Site Investigations for North America, and Rick Ahlers, global lead for NAPL Management.
