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.
