FAQS - PETROLEUM MARKETERS/UST

Q:How do I become Trust Fund eligible?
A: An application with the Mississippi Department of Environmental Quality (MDEQ), Underground Storage Tank (UST) Branch, will need to be submitted for review and approval.
Q:Does it matter who I hire to do work at my UST facility?
A:Yes. You should always ask any contractor for qualifications, certification and experience (references).
Q:If my facility happens to need Groundwater and/or Soil Remediation, how long will it take to clean up?
A:Depending on geological conditions, remediation averages 36 months (based on MDEQ records). At HAZCLEAN we believe that faster clean up time will be achieved utilizing our remediation system design and implementation. (We have remediated three (3) sites within twelve (12) months from startup. How many other firms are doing that?)
Q:Why does a Preliminary Subsurface Investigation need to be conducted?
A:A release of motor fuel into the environment has occurred at the facility. Soil Borings/Monitoring Wells need to be installed to determine the extent (vertical and horizontal) of the contamination.
Q:What do I need to do with all the paperwork that MDEQ and my contractor send me?
A:Keep all reports, correspondence, and associated paperwork for future reference. If any questions arise, call your contractor Project Manager.
Q:Why do you sample groundwater?
A:Groundwater samples are required to establish constituents of concern, such as Benzene, Toluene, Ethylbenzene, and Total Xylenes (BTEX). If the laboratory results are above the MDEQ, UST Branch Action Levels for any of the analyzed parameters, more action will need to be addressed at the site in order to receive No Further Action status from the MDEQ.
Q:What is the purpose of boring holes in the ground if you already know where the contamination is coming from?
A:The motor fuel which was released is migrating through the soils until encountering a confining layer or groundwater. Since the Free Product is migrating, soil borings are required to define the extent of contamination – vertically and horizontally. We need to know how far and how deep in order to quickly and efficiently remediate your facility.
Q:How do you determine where to place your monitoring wells?
A:Guidelines have been set by MDEQ for proper placement of groundwater monitoring wells. The wells should be placed upgradient and downgradient of the release and near product lines, dispensers, USTs and property lines to fully determine the vertical and horizontal extent of contamination.
Q:What do you sample for when sampling the groundwater monitoring and/or tankbed observation wells?
A:If the MDEQ requests a Preliminary Subsurface Investigation (PSI) at your facility, the soil and groundwater samples will be analyzed for BTEX and Polynuclear Aromatic Hydrocarbons (PAHs). If continuing sampling event are necessary and PAH results were all below detection levels during the PSI, likely no PAH samples will be collected during future sampling activities. BTEX samples will be taken if required during follow up sampling activities.
Q:What is the purpose of a vacuum truck?
A:A vacuum truck is used on sites which need remediation of small plumes of contamination or for Pilot Test Studies for designing remediation system criteria. Usually (based on experience) vacuum trucks will not be a cost-effective remediation tool.
Q:Why do you need a groundwater remediation system (GRS) if you can use a vacuum truck?
A:A GRS is a dedicated system which operates 24 hours a day, seven days a week, 365 days a year to clean up your site. Having a vacuum truck and operator work those hours is not feasible. A vacuum truck is utilized for short term problems.
Q:When a gasoline dispenser, or a UST leaks, how does the plume of contamination migrate through the soil?
A:Migration of contamination occurs through pore spaces (voids) within the soil. Different soil types contain different voids. Depending on the soil type, contaminant migration will occur at different rates. Sands usually transport contaminants quickly, where clay soils transport slowly. Thus, when you ask, “How long will my site take to clean up?” you could already know that a sandy soil will clean up faster than a clayey soil.
Q:What is the purpose of the Leaking Underground Storage Tank (LUST) Trust Fund?
A:It is more or less an insurance policy for UST owners who keep up their yearly tank fees, maintain their tanks to regulatory standards, monitors tanks and associated piping, and contacts MDEQ with release information.
