Current through June 25, 2024
A change in service is when the contents of the tank
						  are changed from a regulated substance (e.g. gasoline) to an unregulated
						  substance (e.g. water). In order to accomplish a change in service, the same
						  notification and sampling requirements for the permanent closure of a UST
						  system must be followed. Sampling must be conducted in the same manner as tank
						  closure in place and the interior of the tank properly cleaned. In addition,
						  you must notify the UST Branch of the change in service by submittal of a
						  "Notification for Underground Storage Tanks" form which indicates what
						  unregulated substance is presently stored in the tank.

Four borings are required when closing in place a
						  single tank less than or equal to 25 feet in length. One borehole at each
						  corner the tank bed must be advanced to a depth of at least one foot below the
						  bottom of the tank and into the native soil as shown in Figure 6. In order to
						  determine the appropriate sampling depth and number of samples to collect,
						  conduct field screening of the soil column following the guidance Section
						  4.4.4.

Current through June 25, 2024
For closure in place of two or more tanks within a
						  common tank bed or a single tank that is greater than 25 feet in length, soil
						  borings must be conducted at intervals of every 25 feet along the perimeter of
						  the tank bed as shown in Figure 7. In order to determine the appropriate
						  sampling depth and number of samples to collect, conduct field screening of the
						  soil column following the guidance in Section 4.4.4.

Current through June 25, 2024
In order to properly evaluate the appropriate depths to
						  collect soil samples, conduct field screening in two foot intervals of the soil
						  column in each boring. Field screening involves placing the soil in a container
						  (normally a zipper-type plastic bag) and evaluating the headspace with a
						  suitable hydrocarbon meter.
Because soils must be relatively undisturbed to obtain
						  accurate field screening results, any boring that is conducted during sample
						  collection/screening must be accomplished in a manner that will produce a
						  "core" of the soil column. Cuttings produced from rotary drilling equipment are
						  not acceptable for either field screening or sample collection.
In order for the field screening to be evaluated by UST
						  staff, a boring log must be submitted along with the analytical results of
						  sampling. The boring log must show the type of soil encountered throughout the
						  length of the boring. The boring log must also show hydrocarbon vapor levels in
						  parts per million as determined by the field screening process for every two
						  feet of the boring. Please refer to Appendix G for an example of an acceptable
						  boring log.
Soil samples must be conducted at the depth at which
						  the highest levels of hydrocarbon vapors were detected during the field
						  screening process. If no significant variations are found during field
						  screening, samples must be collected from a depth of at least one foot below
						  the bottom of the tanks into the native soil. If the field screening process
						  reveals that all samples should be collected at less than maximum depths, at
						  least one additional sample must be collected from the borehole that had the
						  highest level of vapors found during the field screening process. This
						  additional sample must be collected from a depth of one foot below the bottom
						  of the tanks and into the native soil.

Current through June 25, 2024
Prior to beginning any sampling activity, all backfill
						  materials must be removed from the excavation. If no contamination of the
						  sidewalls is apparent, one soil sample must be collected from the floor of the
						  excavation. The sample must be collected at a depth of one foot below the
						  piping trench and into the native soil. The sample must be collected from the
						  area of the floor that appears to be the most contaminated. If no area of the
						  floor appears to be contaminated, the sample must be collected from the center
						  of the excavation when the dispenser island is less than or equal to 50 feet in
						  length as shown if Figure 8.
Two soil samples must be taken below each dispenser
						  island if the island is more than 50 feet in length. The samples must be
						  collected from beneath the piping trench at least one foot into the native
						  soil. The samples must be collected from the areas of the floor that appears to
						  be contaminated although no more than 50 feet may exist between any two sample
						  locations. If no area of the floor appears contaminated, the sample locations
						  must be spaced equally along the length of the island and such that no more
						  than 50 feet exists between any two sampling locations as shown in Figure
						  8.

Current through June 25, 2024
If any of the sidewalls of the excavation appear to be
						  contaminated, the sidewalls must be sampled. At least two samples are required
						  for dispenser islands less than 50 feet in length when sidewall sampling is
						  necessary. One sample must be collected from the area of the sidewall that
						  appears to be the most contaminated. The second sample must be collected from
						  the floor of the excavation where the most contamination appears to be present.
						  The second sample must be collected from the floor of the piping trench and at
						  least one foot into the native soil. If no area of the floor appears
						  contaminated or it appears uniformly contaminated, the sample must be collected
						  as shown in Figure 8.
If the dispenser island is greater than 50 feet in
						  length and sidewall sampling is necessary, at least three samples are required.
						  One of the samples must be collected from the area of the sidewall that appears
						  to be the most contaminated. The other two samples must be collected from the
						  floor of the excavation where the most contamination appears to be present.
						  However, you should also take into consideration the entire area of the
						  excavation so that both of the floor samples are not collected from the same
						  general area. If no area of the floor appears contaminated or if it appears
						  uniformly contaminated, collected floor samples as shown in Figure
						  8.

Current through June 25, 2024
Since potentially contaminated soils cannot be seen
						  during closure in place activities as when excavating, the sampling
						  requirements for closure in place are more conservative. You must follow the
						  exact guidelines given in this document unless special circumstances do not
						  allow such. Any alternative sampling plan must be submitted to the UST Branch
						  for approval at the same time the "Notice of Intent to Permanently Close UST
						  System(s)" form is submitted.
Soil borings must be conducted at each end of the
						  dispenser island and along the length of the island such that no more than 25
						  feet exists between any two borings as shown in Figure 9. The borings must
						  extend to a depth of at least one foot below the bottom of the piping trench
						  and into the native soil. Samples must be collected from each boring following
						  the field screening practices as described in Section 4.4.4. If "true"
						  groundwater (refer to Section 3.2) is encountered during soil boring
						  activities, groundwater samples must be collected from each boring that
						  contains groundwater and each sample must be analyzed separately. Soil sampling
						  must be conducted from those borings that do not have groundwater. In addition,
						  regardless of whatever soil and/or groundwater sampling that is conducted, one
						  soil sample must be collected from the boring that exhibited the highest level
						  of petroleum contamination during the field screening process.

Current through June 25, 2024
If any of the sidewalls of the piping trench excavation
						  appear to be contaminated, the sidewalls must be sampled. Samples must be
						  collected from the areas of the sidewalls that appear to be the most
						  contaminated. However, sampling must be conducted so that no more than 50 feet
						  exists between any two sampling points.
If the site conditions are such that the sidewalls are
						  the appropriate locations for all samples, at least one of the samples must be
						  collected from the floor of the piping trench excavation where the most
						  contamination appears to be present. The sample must be collected at a depth of
						  at least one foot below the piping trench and into the native soil. If no area
						  of the floor appears contaminated or it appears uniformly contaminated, the
						  sample must be collected at the midpoint of the piping
						  trench.

Current through June 25, 2024
All
excavated backfill material must be
						sampled unless it is disposed of in an approved sanitary landfill. This is
						because the soil samples collected from the native soil of the tank excavation
						may not be representative of the contamination levels of the backfill
						materials.
A minimum of one soil sample is required to be collected
						for each 100 cubic yards of material. Sample the backfill material as soon as
						possible after stockpiling. The samples must be collected at a point at least
						one foot into the stockpile following the same sample collection procedures as
						for any other soil sampling. The backfill samples must be analyzed for the same
						constituents as the tank excavation samples.
Mississippi Administrative Code › Title 11 - Mississippi Department of Environmental Quality › Part 5 - Underground Storage Tank Regulations › Chapter 2 - Mississippi Commission on Environmental Quality Underground Storage Tanks Regulations Technical Standards and Corrective Action Requirements for Owners and Operators of Underground Storage Tanks (UST) (Adopted March 22, 1989; Amended August 25, 2011, Last Amended August 23, 2018) › Appendix 11-5-2-280.4 - GUIDELINES FOR THE PERMANENT CLOSURE OF PETROLEUM UNDERGROUND STORAGE TANK SYSTEMS › Section 11-5-2-280.4-6 - BACKFILL SAMPLING › Section 11-5-2-280.4-6.2 - Backfill Handling Options

Current through June 25, 2024
Typically, all backfill material is contaminated and
						should be handled as such until laboratory analysis proves otherwise. The
						following are the options allowed for handling the backfill material:
a. Dispose of in an approved landfill
					 (Appendix B).
Conduct any sampling that may be required by the
landfill
and receive permission from the landfill you wish to
						utilize.
b. Stockpile on
					 site and await the lab results of sampling.
All backfill material should be placed on and covered
						with an impervious material (plastic sheeting). If the analytical results of
						the backfill material are below the action levels of the UST Branch, the
						backfill material may be placed back into the excavation. If the results are
						above our limits, your options are as described in paragraphs a, d or e of this
						rule.
c. Sample the
					 backfill material and return it to the excavation.
The backfill material may be returned to the
						excavation before the analytical results are obtained with the understanding
						that the backfill material may have to be re-excavated if the analytical
						results arc above the action levels of the UST Branch. If the results are above
						the action levels of the UST Branch, your options are as described in
						paragraphs a, d or e of this rule.
d. Aerate the backfill material on site.
If the analytical results indicate concentrations above
						the action levels of the UST Branch and the owner does not want to dispose of
						the backfill material in an approved sanitary landfill, the backfill material
						may be aerated on site. To aerate the backfill material, place the backfill
						material on an impervious material (plastic sheeting), spread the backfill
						material approximately one foot thick. Build a berm around the soil that will
						retain any rainwater and prevent any contamination from spreading. Cover the
						soil on rainy days; uncover the soil on sunny days. Disc or till the soil
						weekly. Contact a UST Branch Project Manager for instructions before initiating
						the aeration process.
e.
					 Stockpile the backfill material at a different location.
Before this is done, approval must be obtained from the
						MDEQ Groundwater Division-Special Waste Section.

Current through June 25, 2024
When circumstances do not allow the collection of samples
						from the locations required in this document, the owner must contact the UST
						Branch and receive prior approval of any alternative sampling plan. Draw a
						sketch of the facility that shows the tank system in relation to any obstacles
						and show the proposed sampling locations.

Current through June 25, 2024
While not generally a recommended practice, sampling
						requirements may be waived if the facility has monitoring wells as the method
						of leak detection and no evidence of a release has been noted. The UST Branch
						generally will only consider groundwater monitoring to grant a waiver. In order
						to request a waiver, submit the previous twelve months of monitoring well
						records at the same time the "Notice of Intent to Permanently Close UST
						System(s)" form is submitted and indicate you wish to have the sampling
						requirements waived.
However, if evidence of petroleum contaminated soil
						and/or groundwater is found during closure activities, samples must then be
						collected from the appropriate locations and analyzed as described in this
						guidance document.

Current through June 25, 2024
The samples must be analyzed for the product last stored
						in the UST (refer to the table below). However, if evidence of a leak from a
						previously stored product is found or it is known that the tank stored a
						different substance at one time, the samples must be analyzed for that
						substance also. For example, all of the tanks have stored gasoline for the past
						several years but it is known that one of the tanks was once used to store
						diesel fuel. Therefore, all samples collected from the tank excavation would
						have to be analyzed for both PAH and BTEX.
In addition, if an excavation contained tanks that stored
						substances that require both BTEX and PAH analysis (i.e. gasoline and diesel
						fuel), all samples collected from the excavation must be analyzed for both BTEX
						and PAH.

Current through June 25, 2024
Samples must be analyzed for the products last
						transferred in the piping. However, if evidence of a leak from a previously
						stored product is found or it is known that the piping transferred a different
						substance at one time, the samples must be analyzed for that substance
						also.
In addition, if both diesel fuel and gasoline piping are
						in the same trench/dispenser island, all samples collected from the piping
						trench/dispenser island must be analyzed for both BTEX and PAH.

Aliquot-
Part of the whole. One sampling
					 location may require two or more discreet containers in order to qualify as an
					 adequate sample. Each sample container is an aliquot.
Aquifer
- Underground bodies of sand or gravel
					 which contains groundwater.
Backfill
- All of the soil which was placed in
					 the excavation when the tank system was installed. In UST systems installed
					 after 1988, the backfill is normally easy to determine since tank systems were
					 required to be backfilled with clean sand or gravel and these materials are
					 easily differentiated from the native soil.
BTEX
- Benzene, Toluene, Ethylbenzene, and
					 Xylenes, the four major components of gasoline.
Convex Meniscus
- Curved or rounded like the
					 outside of
a
circle.
Decontamination
- A process in which to clean
					 and remove contaminants from sample equipment and devices with detergent wash
					 following a series of rinses with distilled water.
Groundwater
- For the purposes of UST
					 closures, it is the naturally occurring water that seeps into the tank
					 excavation from the aquifer.
Headspace
- The air space between the sample
					 and the top of the closed container.
Holding time
- The length of time allowed
					 between sample collection and analysis by the laboratory.
Native soil
- Soil which has been undisturbed
					 by activities of man.
PAH
- Polynuclear Aromatic
					 Hydrocarbons.
Preservative
- A chemical added to a water
					 and/or soil samples to prevent deterioration or to maintain the original
					 characteristics.
Repair
- To restore a piping system. Repair as
					 utilized in this document means that some minor component, such as a flex
					 connector or a coupling/union, of the piping system has been replaced or simply
					 tightened.
Septum cap
- A sample container cap that has a
					 membrane for extracting water with a syringe.
Stockpiling
- Storing excavated materials on
					 site. Correct stockpiling requires putting the excavated material on plastic at
					 a height not greater than 3 feet. A berm should surround the stockpiled
					 material in order to prevent rainwater run-off.
Teflon lined
- A synthetic liner used to line
					 the sides and caps of sample containers to prevent samples from
					 sticking.
VOC
- Volatile Organic Compounds - chemicals
					 which readily vaporize under normal atmospheric conditions.
