Current through June 25, 2024
For both galvanic and impressed current systems, if
						  more than 100 feet of piping exists between any two anodes, the reference
						  electrode must also be placed at the midpoint between the two anodes that are
						  separated by more than 100 feet (see Figure 12). In addition, if it is not
						  known where the piping anodes are located, there can be no more than 100 feet
						  of piping between any two test points. This midpoint placement is in addition
						  to any other reference electrode placement that may be required as noted above
						  in Sections 6.10.1 through 6.10.

Current through June 25, 2024
If any modification to the construction of the cathodic
						  protection system is made (e.g. supplemental anodes) it is necessary to show
						  the modification on the "as built" drawings. If no as built drawing is
						  available, you must indicate the location of any anode addition on the site
						  drawing that is constructed as part of the evaluation. As built drawings are
						  required whenever a cathodic protection system is installed or substantially
						  modified. The drawings should include: a) how many anodes were installed; b)
						  what type of anodes were installed; c) where were the anodes installed; d) how
						  deep were the anodes installed; e) what type of wire was used; 0 how were the
						  wires bonded, etc.

Current through June 25, 2024
Whenever a cathodic protection survey is conducted, a
						  site drawing depicting the UST system, the cathodic protection system and any
						  related features of the facility must be constructed. In addition, you must
						  indicate on the drawing where the reference electrode was placed for each of
						  the structure-to-soil potentials utilized to obtain a pass. Figure 13 is an
						  example of a site drawing that shows the type of information that is necessary
						  to properly complete the evaluation.
While it is understood that you will not always know
						  where all of the pertinent components of the cathodic protection system may be
						  buried, all that is known must be indicated. It is very important to show where
						  the anodes are located on the site drawing. If you do not know where the anodes
						  are buried, voltage gradients in the soil may help you determine the
						  approximate location as described in the raised earth discussion of Section
						  6.3.
Should any modifications to the cathodic protection
						  system be made, it is very important that such modifications be both visually
						  indicated on the site drawing and a written narrative made that describes the
						  work conducted. If as built drawings are available, it is acceptable to utilize
						  these drawings for the purposes of meeting the requirements of this rule. Any
						  modifications or changes to the UST and/or cathodic protection systems that
						  have been made since the construction of the as built drawings must be
						  included.

Current through June 25, 2024
Whenever a cathodic protection survey is conducted in
						  the State of Mississippi, the appropriate form (s) prescribed by the MDEQ
						  (Appendix K and/or L) must be utilized to document the survey. However, use of
						  the prescribed form(s) is not intended to limit other kinds of documentation
						  that may be desirable in order to complete the evaluation. For instance, it may
						  be necessary to provide a written narrative describing various aspects of the
						  evaluation or a repair/modification that are not captured by completion of the
						  form(s) them selves.
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 11-5-2-280.1 - GUIDELINES FOR THE EVALUATION OF UNDERGROUND STORAGE TANK CATHODIC PROTECTION SYSTEMS › Section 11-5-2-280.1-7 - DOCUMENTATION OF EVALUATION › Section 11-5-2-280.1-7.2 - Corrosion Expert's Evaluation

Current through June 25, 2024
Because the MDEQ has allowed those individuals who may
						only have minimal training in the principles of cathodic protection to conduct
						testing of such systems, it must be recognized that there will be instances
						where the expertise of someone who is more qualified and better understands the
						principles involved will be necessary.
Some of the more obvious scenarios where a person with a
						level of expertise equivalent to a "corrosion expert" {as defined in Section
						2.1 (280.12) of this document} are
						necessary are given below. If any of the conditions given below are met, a
						corrosion expert must evaluate the survey results obtained by a tester and/or
						conduct further testing and complete Section VII of the MDEQ cathodic
						protection system evaluation form(s). If the structure-to-soil potential survey
						is conducted by a person who is qualified as a corrosion expert, completion of
						Section VII of the MDEQ form(s) is all that is necessary.
A corrosion expert is required to evaluate and/or conduct
						the survey when:
1. Supplemental anodes
					 are added to a galvanic cathodic protection system and an accepted industry
					 standard is not followed and/or properly documented.
2. Supplemental anodes or other changes in
					 the construction of an impressed current system are made.
3. It is known or suspected that stray
					 current may be affecting the protected structure.
4. The repair and/or addition of supplemental
					 anodes to bare steel/galvanized piping that is galvanically protected (see
					 Section 5.1.3 ).
5. An inconclusive
					 was declared when testing a galvanically protected structure because both the
					 local and the remote potentials did not indicate the same result (one indicated
					 pass but the other indicated fail).
Although not specifically listed above, it should be
						recognized that there might be additional circumstances that may arise that
						will require evaluation, and/or design by a corrosion expert.
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 11-5-2-280.1 - GUIDELINES FOR THE EVALUATION OF UNDERGROUND STORAGE TANK CATHODIC PROTECTION SYSTEMS › Section 11-5-2-280.1-7 - DOCUMENTATION OF EVALUATION › Section 11-5-2-280.1-7.3 - What if the Evaluation Result is Fail?

Current through June 25, 2024
It is important to properly notify the tank owner if an
						evaluation of the cathodic protection system fails. Necessary repairs should be
						accomplished within 90 days of receipt of the "failed" evaluation. The tank
						owner is responsible for ensuring that the cathodic protection system is
						maintained in a manner that will provide adequate corrosion protection to the
						UST system.
As it is recognized that many factors may cause a lower
						than desired voltage to be obtained during a structure-to-soil survey, there
						may be several different courses of action appropriate to resolve the "fail".
						For instance, it is not uncommon to simply retest a sti-P3 tank that has failed
						a cathodic protection survey at a later date and achieve a passing
						result.
Therefore, a 90-day re-testing period is allowed whenever
						a fail is obtained during which no action is necessary to repair or modify the
						cathodic protection system. This applies only to those galvanic and impressed
						current systems that appear to be in good working condition. If there are
						obvious problems with a system or you are unable to achieve a pass within the
						90-day window, the tank owner must make any repairs and/or modifications that
						are necessary to achieve a pass. Repairs and/or modifications must be completed
						as soon as practical but no more than 90 days should be allowed after
						expiration of the "90 day window".

Current through June 25, 2024
Soil and/or groundwater samples must be collected to
						determine if a release has occurred. The importance of good sampling procedures
						is critical to the assessment of a site at a UST closure. Since gasoline and
						some other petroleum products consist largely of volatile organic compounds,
						special care in collecting samples is required. Special precautions must be
						taken to be certain that samples collected from each site are representative of
						the soil and/or groundwater at that location and that the sample is neither
						altered nor contaminated by the sampling and handling procedure.
When collecting samples for Benzene, Toluene,
						Ethylbenzene and Xylenes (BTEX) analysis, new disposable latex or nitrile
						gloves must be worn at each sample collection location. When collecting samples
						for Polynuclear Aromatic Hydrocarbons (PAH) analysis, new disposable vinyl or
						nitrile gloves must be worn at each sample collection location. Latex is not a
						suitable glove material when collecting samples for PAH analysis since PAH's
						have an affinity for latex.
The minimum number of sample containers (i.e. aliquots)
						that are stated in this document are only intended to be guidance. Always
						contact your laboratory to determine the sample size and aliquots that are
						required for a particular laboratory.
All samples must be placed in proper containers
						immediately upon collection, properly packaged and labeled with the following
						minimum information:
1. facility
					 name
2. sample location (e.g. NW
					 corner of tank bed, Sample #1, etc.)
3. date and time samples were
					 collected
4. depth samples were
					 collected
5. person collecting
					 samples
6. analytical test(s)
					 required
All
samples must be placed on ice
						immediately after collection and shipped to the laboratory within 24 hours of
						collection.

Current through June 25, 2024
Soil samples must be collected whenever evidence of soil
						contamination exists. However, if water is encountered, pump it out in
						accordance with all regulatory requirements and determine if the water in the
						tank excavation or borehole returns within 24 hours. If the water returns,
						assume that the water is true groundwater. If groundwater is present, water
						sample(s) must be collected. If groundwater is sampled, no soil sampling is
						required unless soil contamination is evident. If soil contamination is evident
						at either the tank excavation or the piping trench/dispenser island, soil
						samples must be collected in accordance with Sections 5-7 of this document in
						addition to any water samples.

Current through June 25, 2024
For BTEX analysis, collect at least one 4-oz sample
						  from each sampling point. The sampling procedure is as follows:
1. Use a stainless steel spoon, spatula or
						some other appropriate sampling device. NOTE: Sampling device must be
						decontaminated between each sampling location.
2. Soil samples should be tightly packed into
						the sample container using the stainless steel spoon or appropriate sampling
						device.
3. Completely fill sample
						container (4-oz widemouth amber glass container with a Teflon liner) so that no
						headspace is present.
4.

Current through June 25, 2024
For PAH analysis, collect at least one 8-oz sample from
						  each sampling point. The sampling procedure is as follows:
1. Use a stainless steel spoon, spatula or
						some other appropriate sampling device. NOTE: Sampling device must be
						decontaminated between each sampling location.
2. Soil samples should be tightly packed into
						the sample container using the stainless steel spoon or appropriate sampling
						device.
3. Completely fill sample
						container (8-oz widemouth amber glass container with a Teflon liner) so that no
						headspace is present.

Current through June 25, 2024
For BTEX groundwater analysis, collect at least three
						  (3) 40-ml samples from each sampling point.
1. Sampling containers should be pre-labeled
						before any sample collection begins.
2. Decontaminate bailer and use clean new
						string/line.
NOTE: In general, use a disposable bailer and not one
						  that must be decontaminated between borings or wells in order to lessen the
						  chance of cross-contamination.
3. Slowly lower the bailer into the water. Do
						not allow the bailer to free-fall.
4. Allow the bailer to go into the water as
						far as possible without touching the bottom of the boring and/or tank
						hole.
5. Remove the bailer from the
						water before it is completely immersed under the water.
6. Collect three aliquots:
a. transfer the sample from the bailer to
						amber 40-ml glass vials with Teflon-lined septum cap, leaving no head space;
b. each sample should be carefully
						poured down the inside of the vial to minimize turbulence;
c. verify no headspace by inverting the vial
						and tapping it gently to check for trapped air bubbles. If any are present, a
						new sample must be collected;
d. as
						a rule of thumb, it is best to gently pour the last few drops into the vial so
						that surface tension holds the water in a "convex meniscus". The cap is then
						placed on the vial and some overflow is lost, but air space in the bottle is
						eliminated;
e. Immediately store
						samples on ice and ship to the laboratory within 24 hours of
						collection.

Current through June 25, 2024
The goal of sampling a tank excavation at closure is to
						represent the contamination which may exist in a manner that is as accurate as
						possible while at the same time minimizing the number of samples that are
						necessary to achieve the stated purpose. Although the sampling locations
						described in this document are the minimum necessary, they are not intended to
						substitute for the conditions which may exist at a particular location.
						Therefore, a certain amount of professional judgement is necessary in order to
						evaluate and properly assess the site conditions at a tank closure.
When conducting sampling at a tank removal, all backfill
						materials must be removed from the excavation prior to sampling. Whether
						sampling the sidewalls or the floor of an excavation, all samples must be
						collected from a depth of at least one foot into the native soil. Soil samples
						shall be collected immediately after the removal of all backfill material. When
						closing tanks in place, the soil borings must be conducted in the native soil
						immediately surrounding the tank bed excavation. Soil samples shall be
						collected immediately after completion of the soil boring.
No compositing of samples (including sampling of the
						backfill) is allowed and each sample that is collected must be analyzed
						separately.
If "true" groundwater (refer to Section 3.2 ) is
						encountered during excavation activities, a groundwater sample must be
						collected from the excavation. No soil sampling is required if a groundwater
						sample is collected unless soil contamination is evident. Any soils that appear
						to be contaminated must be sampled in addition to sampling of the groundwater.
						Follow the soil sampling requirements as described in Sections 5-7 of this
						document when soil sampling is necessary.

Current through June 25, 2024
If no contamination is apparent in the sidewalls, only
						  floor sampling is required. Two samples must be collected from the floor of the
						  excavation at a depth of one foot into the native soil. The samples must be
						  collected from the areas of the floor that appear to be the most contaminated.
						  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 to be obviously contaminated, or
						  the floor appears to be uniformly contaminated, the samples must be collected
						  from each end of the excavation as shown in Figure 1.

Current through June 25, 2024
If
any of the sidewalls appear to be
						  contaminated, sidewall samples must be collected. As shown in Figure 2 below, a
						  minimum of three samples are required to assess the excavation when the
						  sidewalls are contaminated. Two samples must be collected from the sidewalls
						  and one from the floor of the excavation.
The first sidewall sample must be collected from the
						  sidewall of the excavation that appears to be the most contaminated. The second
						  sample must be collected from one of the three remaining sidewalls that appears
						  to have the greatest remaining contamination. If no other sidewall appears to
						  be contaminated, the second sample must be collected from the wall opposite of
						  the sidewall which appears to be the most contaminated. The third sample to be
						  collected must come from the floor of the excavation. The floor sample must be
						  collected from the area of the floor that appears to be the most contaminated.
						  If no area of the floor appears contaminated or if it appears uniformly
						  contaminated the sample must be collected from the center of the
						  excavation.

Current through June 25, 2024
If no contamination is apparent in the sidewalls, only
						  floor sampling is required. When the excavation is 50 feet or less in all
						  dimensions, four samples must be collected from the floor of the excavation at
						  a depth of one foot into the native soil. The samples must be collected from
						  the areas of the floor that appear to be the most contaminated. However, you
						  should also take into consideration the entire area of the excavation so that
						  no two of the samples are collected from the same general area. If no area of
						  the floor appears to be obviously contaminated, or the floor appears to be
						  uniformly contaminated, the samples must be collected from each corner of the
						  excavation as shown in Figure 3.

However, if the excavation is greater than 50 feet in
						  any dimension, additional samples must be collected along each dimension of the
						  excavation that is greater than 50 feet in length. The additional sample must
						  be collected from the center of that dimension of the excavation as shown in
						  Figure 4. Soil sampling must also be conducted in such a manner that no more
						  than 50 feet exists between any two sampling points as measured along each
						  dimension (side) of the excavation.

Current through June 25, 2024
If any of the sidewalls appear to be contaminated, all
						  of the sidewalls must be sampled. As shown in Figure 5 below, a minimum of five
						  samples are required to assess the excavation when the sidewalls are
						  contaminated. One sample must be collected from each of the four sidewalls and
						  one from the floor of the excavation. The sidewall samples must be collected
						  from the area of each sidewall that appears to be the most contaminated. If a
						  wall appears to be clean, the sample for that uncontaminated wall must be
						  collected from the same depth where the highest level of contamination appears
						  in the most contaminated wall of the excavation.
The fifth sample must come from the floor of the
						  excavation. The floor sample must be collected from the area of the floor that
						  appears to be the most contaminated. If no area of the floor appears
						  contaminated or if it appears uniformly contaminated, the sample must be
						  collected from the center of the excavation.
Soil sampling must also be conducted in such a manner
						  that no more than 50 feet exists between any two sampling locations along each
						  wall of the excavation.
