MACK’S OIL, VA PC#94-0486
Description of Role: Primary Environmental Contractor
Project Team Leader(s): Andrew Alden, Jeffrey A. Fisher, Jr.
DEQ Region and Case Coordinator: WCRO, Vince Maiden
Project Cost: $18,925.00
Time Period of Project Work: October 1999 to July 2003
Client: Mack’s Oil
Client Representative: Mr. Robert Saunders
Introduction:
Environmental Engineering, Inc. (EEI) is presenting this project as an
example of EEI’s ability to assume project management from a previous
consultant and provide additional characterization towards the
successful closure of a petroleum complaint generated by a diesel-range
petroleum release of unknown quantity at an AST farm.
Scope of Work:
This petroleum release was discovered in September of 1993 during the
installation of vapor monitoring wells inside the AST secondary
containment area at Mack’s Oil in Pocahontas, Virginia. Several
consulting companies handled this project before EEI was hired by Mack’s
Oil in April of 2000 to complete all required characterization and
cleanup activities. After the review of several CAP monitoring reports
submitted by NuTek, International, Inc., the DEQ requested that a CAP
Addendum be submitted for the site due to the continued presence of
elevated concentrations of residual-phase petroleum on-site. EEI
performed CAPA activities that included repair of several monitoring
wells, which had been damaged due to neglect and the improper collection
of water samples.
In August of 2000, EEI prepared and submitted a CAPA that included the
results of site monitoring and dissolved-phase sampling. This report
identified the potential receptors, presented up-to-date dissolved-phase
data, proposed endpoints, and outlined a course of action that included
additional characterization and the cessation of a bioremediation system
that was not performing efficiently.
EEI then performed two consecutive semi-annual dissolved-phase
monitoring events, the data from which suggested no evidence of
contaminant migration, nor any increase in concentrations with respect
to data presented in previous investigations. Based on these data, and
other information gathered to date, EEI recommended that the site be
considered for closure.
The DEQ approved this request, and in April of 2002 EEI properly
abandoned the seven monitoring wells and submitted documentation to that
effect in a Site Closure letter.
Staff and Resource Involvement:
Mr. Alden provided engineering oversight and project management
assistance throughout EEI’s tenure with this project. Mr. Fisher was
responsible for project management during the post CAPA monitoring
phase, which included drafting two post CAPA monitoring reports. EEI
field technicians collected all field data and operated all equipment
and machinery.
