the tank's height to the nearest one-eighth of an inch [3.05 millimeters];
c. The regulated substance inputs are reconciled with delivery receipts by measurement of
the tank inventory volume before and after delivery;
d. Deliveries are made through a drop tube that extends to within one foot [0.30 meters] of
the tank bottom;
e. Product dispensing is metered and recorded within the local standards for meter
calibration or an accuracy of six cubic inches [98.32 milliliters] for every five gallons
[18.93 liters] of product withdrawn; and
f. The measurement of any water level in the bottom of the tank is made to the nearest
one-eighth of an inch [3.05 millimeters] at least once a month.

guidance in meeting the requirements.
2. Manual tank gauging. Manual tank gauging must meet the following requirements:
a. Tank liquid level measurements are taken at the beginning and ending of a period using
the appropriate minimum duration of test value in the table below during which no liquid
is added to or removed from the tank;
b. Level measurements are based on an average of two consecutive stick readings at both
the beginning and ending of the period;
c. The equipment used is capable of measuring the level of product over the full range of
the tank's height to the nearest one-eighth of an inch [3.05 millimeters];
d. A release is suspected and subject to the requirements of sections 33.1-24-08-40
through 33.1-24-08-43 if the variation between beginning and ending measurements
exceeds the weekly or monthly standards in the following table:
Monthly Standard

with a nominal capacity of five hundred fifty-one to one thousand gallons [2,085.76 to
3,785.41 liters] which meet the tank diameter criteria in the table in subdivision d may
use this as the sole method of release detection. All other tanks with a nominal capacity
of five hundred fifty-one to two thousand gallons [2,085.76 to 7,570.80 liters] may use
this method in place of inventory control in subsection 1. Tanks of greater than
two thousand gallons [7,570.80 liters] nominal capacity may not use this method to meet
the requirements of sections 33.1-24-08-30 through 33.1-24-08-35.
3. Tank tightness testing. Tank tightness testing (or another test of equivalent performance)
must be capable of detecting a one-tenth gallon [.38 liter] per hour leak rate from any portion
of the tank that routinely contains product while accounting for the effects of thermal

(2) Continuous in-tank leak detection operating on an uninterrupted basis or operating
within a process that allows the system to gather incremental measurements to
determine the leak status of the tank at least once every thirty days.
5. Vapor monitoring. Testing or monitoring for vapors within the soil gas of the excavation zone
must meet the following requirements:
a. The materials used as backfill are sufficiently porous (for example, gravel, sand, crushed
rock) to readily allow diffusion of vapors from releases into the excavation area;
b. The stored regulated substance, or a tracer compound placed in the tank system, is
sufficiently volatile (for example, gasoline) to result in a vapor level that is detectable by
the monitoring devices located in the excavation zone in the event of a release from the
tank;
c. The measurement of vapors by the monitoring device is not rendered inoperative by the
ground water, rainfall, or soil moisture or other known interferences so that a release
could go undetected for more than thirty days;
d. The level of background contamination in the excavation zone will not interfere with the
method used to detect releases from the tank;
e. The vapor monitors are designed and operated to detect any significant increase in
concentration above background of the regulated substance stored in the tank system, a
component or components of that substance, or a tracer compound placed in the tank
system;
f. In the underground storage tank excavation zone, the site is assessed to ensure
compliance with the requirements in subdivisions a through d and to establish the
number and positioning of monitoring wells that will detect releases within the excavation
zone from any portion of the tank that routinely contains product; and

than one;
b. Ground water is never more than twenty feet [6.07 meters] from the ground surface and
the hydraulic conductivity of the soils between the underground storage tank system and
the monitoring wells or devices is not less than one one-hundredths centimeter per

second (for example, the soil should consist of gravels, coarse-to-medium sands, coarse
silts or other permeable materials);
c. The slotted portion of the monitoring well casing must be designed to prevent migration
of natural soils or filter pack into the well and to allow entry of regulated substance on the
water table into the well under both high and low ground water conditions;
d. Monitoring wells must be sealed from the ground surface to the top of the filter pack;
e. Monitoring wells or devices intercept the excavation zone or are as close to it as is
technically feasible;
f. The continuous monitoring devices or manual methods used can detect the presence of
at least one-eighth of an inch [3.05 millimeters] of free product on top of the ground water
in the monitoring wells;
g. Within and immediately below the underground storage tank system excavation zone,
the site is assessed to ensure compliance with the requirements in subdivisions a
through e and to establish the number and positioning of monitoring wells or devices that
will detect releases from any portion of the tank that routinely contains product; and
h. Monitoring wells are clearly marked and secured to avoid unauthorized access and
tampering.
7. Interstitial monitoring. Interstitial monitoring between the underground storage tank system
and a secondary barrier immediately around or beneath it may be used, but only if the system
is designed, constructed, and installed to detect a leak from any portion of the tank that
routinely contains product and also meets one of the following requirements:
a. For double-walled underground storage tank systems, the sampling or testing method
can detect a leak through the inner wall in any portion of the tank that routinely contains
product;
b. For underground storage tank systems with a secondary barrier within the excavation
zone, the sampling or testing method used can detect a leak between the underground
storage tank system and the secondary barrier;
(1) The secondary barrier around or beneath the underground storage tank system
consists of artificially constructed material that is sufficiently thick and impermeable
(at least 10-6 centimeter per second for the regulated substance stored) to direct a
leak to the monitoring point and permit its detection;
(2) The barrier is compatible with the regulated substance stored so that a release from
the underground storage tank system will not cause a deterioration of the barrier
allowing a release to pass through undetected;
(3) For cathodically protected tanks, the secondary barrier must be installed so that it
does not interfere with the proper operation of the cathodic protection system;
(4) The ground water, soil moisture, or rainfall will not render the testing or sampling
method used inoperative so that a release could go undetected for more than thirty
days;
(5) The site is assessed to ensure the secondary barrier is always above the ground
water and not in a twenty-five-year floodplain, unless the barrier and monitoring
designs are for use under such conditions; and

(6) Monitoring wells are clearly marked and secured to avoid unauthorized access and
tampering.
c. For tanks with an internally fitted liner, an automated device can detect a leak between
the inner wall of the tank and the liner, and the liner is compatible with the substance
stored.
8. Statistical inventory reconciliation. Release detection methods based on the application of
statistical principles to inventory data similar to those described in subsection 1 must meet the
following requirements:
a. Report a quantitative result with a calculated leak rate;
b. Be capable of detecting a leak rate of two-tenths gallon per hour or a release of one
hundred fifty gallons within thirty days; and
c. Use a threshold that does not exceed one-half the minimum detectible leak rate.
9. Other methods. Any other type of release detection method, or combination of methods, can
be used if:
a. It can detect a two-tenths gallon [.76 liter] per hour leak rate or a release of one hundred
fifty gallons [567.81 liters] within a month with a probability of detection of ninety-five
hundredths and a probability of false alarm of five one-hundredths; or
b. The department may approve another method if the owner and operator can
demonstrate that the method can detect a release as effectively as any of the methods
allowed in subsections 3 through 8. In comparing methods, the department shall consider
the size of release the method can detect and the frequency and reliability with which it
can be detected. If the method is approved, the owner and operator must comply with
any conditions imposed by the department on its use to ensure the protection of human
health and the environment.

### § 33.1-24-08-37. Criteria for delivery prohibition.

1. An underground storage tank shall be classified as ineligible for delivery, deposit, or
acceptance of product upon determination by the department that the underground storage
tank meets one or more of the following conditions:
a. Spill prevention equipment as required by this chapter is not installed;
b. Overfill protection equipment as required by this chapter is not installed;
c. Leak detection equipment as required by this chapter is not installed;
d. Corrosion protection equipment as required by this chapter is not installed; or
e. Other conditions which the department determines may present an imminent and
substantial endangerment to public health and the environment.
2. The department may also classify an underground storage tank as ineligible for delivery,
deposit, or acceptance of product if the owner or operator of that tank has been issued a
written warning or citation (for example, field citation, warning letter, notice of violation), and
has failed to take corrective action, within a reasonable period of time determined by the
department, under any of the following circumstances:
a. Failure to properly operate or maintain leak detection equipment;
b. Failure to properly operate or maintain spill, overfill, or corrosion protection equipment;
c. Failure to insure owners and operators of underground storage tank systems have
designated class A, class B, and class C operators;
d. Failure to maintain financial responsibility;
e. Failure to protect a buried metal flexible connector from corrosion; or
f. Other conditions which the department determines may present an imminent and
substantial endangerment to public health and the environment.
3. The department shall retain the discretion to decide whether to identify an underground
storage tank as ineligible to deliver, deposit, or accept product based on whether the
prohibition is in the best interest of the public. In those cases where prohibition of delivery,
deposit, or acceptance of product to an underground storage tank is not in the best interest of
the public (for example, certain emergency generator underground storage tanks), the
department may classify an underground storage tank as ineligible to receive product, but
authorize an emergency delivery.
4. The department may also consider not treating an underground storage tank as ineligible for
delivery, deposit, or acceptance of product if such treatment would jeopardize the availability
of, or access to, motor fuel in any rural and remote areas. The department shall only defer
application of delivery prohibition for up to one hundred eighty days after determining an
underground storage tank is ineligible for delivery, deposit, or acceptance of product.

### § 33.1-24-08-38. Mechanisms for designating tanks ineligible for delivery.

1. Upon identifying an underground storage tank as ineligible for delivery, deposit, or acceptance
of product, the department shall notify tank owners or operators in writing (for example, field
notification or mail) prior to prohibiting the delivery, deposit, or acceptance of product into the
ineligible tank.
2. After reasonable effort is made to notify the underground storage tank owner or operator in
writing, the department may affix a "red tag" to the fill pipe of the noncompliant underground
storage tank system using a tamper-resistant strap or straps, fill pipe bag, or any combination
thereof so the tag clearly identifies the tank as ineligible to receive product.
3. The department shall develop a process and procedure for notifying transfer operators when
an underground storage tank is ineligible for delivery, deposit, or acceptance of product.
Notice shall be made available (for example, electronic listing) to transfer operators within
twenty-four hours of an underground storage tank being identified as ineligible to receive
product.

3. Monitoring results, including investigation of an alarm, from a release detection method
required under sections 33.1-24-08-31 and 33.1-24-08-32 that indicate a release may have
occurred unless:
a. The monitoring device is found to be defective, and is immediately repaired, recalibrated,
or replaced, and additional monitoring does not confirm the initial result;
b. The leak is contained in the secondary containment and:
(1) Except as provided for in paragraph 4 of subdivision b of subsection 7 of section
33.1-24-08-33, any liquid in the interstitial space not used as part of the interstitial
monitoring method (for example, brine filled) is immediately removed; and
(2) Any defective system equipment or component is immediately repaired or replaced.
c. In the case of inventory control, described in subsection 1 of section 33.1-24-08-33, a
second month of data does not confirm the initial result or the investigation determines
no release has occurred; or
d. The alarm was investigated and determined to be a nonrelease event (for example, from
a power surge or caused by filling the tank during release detection testing).

### § 33.1-24-08-42. Release investigation and confirmation steps.

Unless corrective action is initiated in accordance with sections 33.1-24-08-50 through
33.1-24-08-57, owners and operators must immediately investigate and confirm all suspected releases
of regulated substances requiring reporting under section 33.1-24-08-40 within seven days, or another
reasonable time period specified by the department, using either the following steps or another
procedure approved by the department:
1. System test. Owners and operators must conduct tests (according to the requirements for
tightness testing in subsection 3 of section 33.1-24-08-33 and subsection 2 of section
section 33.1-24-08-23).

a. The test must determine whether:
(1) A leak exists in that portion of the tank that routinely contains product, or the
attached delivery piping; or
(2) A breach of either wall of the secondary containment has occurred.
b. If the system test confirms a leak into the interstice or a release, owners and operators
must repair, replace, upgrade, or close the underground storage tank system, and begin
corrective action in accordance with sections 33.1-24-08-50 through 33.1-24-08-57 if the
test results for the system, tank, or delivery piping indicate that a release exists.
c. Further investigation is not required if the test results for the system, tank, and delivery
piping do not indicate that a release exists and if environmental contamination is not the
basis for suspecting a release.
d. Owners and operators must conduct a site check as described in subsection 2 if the test
results for the system, tank, and delivery piping do not indicate that a release exists but
environmental contamination is the basis for suspecting a release.
2. Site check. Owners and operators must measure for the presence of a release where
contamination is most likely to be present at the underground storage tank site. In selecting
sample types, sample locations, and measurement methods, owners and operators must
consider the nature of the stored substance, the type of initial alarm or cause for suspicion,
the type of backfill, the depth of ground water, and other factors appropriate for identifying the
presence and source of the release.
a. If the test results for the excavation zone or the underground storage tank site indicate
that a release has occurred, owners and operators must begin corrective action in
accordance with sections 33.1-24-08-50 through 33.1-24-08-57.
b. If the test results for the excavation zone or the underground storage tank site do not
indicate that a release has occurred, further investigation is not required.

a. Spill or overfill of petroleum that results in a release to the environment that exceeds
twenty-five gallons [94.63 liters] or another reasonable amount specified by the
department, or that causes a sheen on nearby surface water; and
b. Spill or overfill of a hazardous substance that results in a release to the environment that
equals or exceeds its reportable quantity under the Comprehensive Environmental
Response, Compensation, and Liability Act [40 CFR 302].
2. Owners and operators of underground storage tank systems must contain and immediately
clean up a spill or overfill of petroleum that is less than twenty-five gallons [94.63 liters] or
another reasonable amount specified by the department, and a spill or overfill of a hazardous
substance that is less than the reportable quantity. If cleanup cannot be accomplished within

twenty-four hours, or another reasonable time period established by the department, owners
and operators must immediately notify the department.
NOTE: A release of a hazardous substance equal to or in excess of its reportable quantity
must also be reported immediately (rather than within twenty-four hours) to the National
Response Center under sections 102 and 103 of the Comprehensive Environmental
Response, Compensation, and Liability Act and to appropriate state and local authorities
under title III of the Superfund Amendments and Reauthorization Act.

### § 33.1-24-08-82. Definitions (financial responsibility).

When used in sections 33.1-24-08-80 through 33.1-24-08-106, the following terms have the
meanings given below:
1. "Accidental release" means any sudden or nonsudden release of petroleum arising from
operating an underground storage tank that results in a need for corrective action or
compensation for bodily injury or property damage, or both, neither expected nor intended by
the tank owner or operator.
2. "Bodily injury" has the meaning given to this term by applicable state law; however, this term
does not include those liabilities which, consistent with standard insurance industry practices,
are excluded from coverage in liability insurance policies for bodily injury.
3. "Chief financial officer", in the case of local government owners and operators, means the
individual with overall authority and responsibility for the collection, disbursement, and use of
funds by the local government.
4. "Controlling interest" means direct ownership of at least fifty percent of the voting stock of
another entity.
5. "Department" means the North Dakota department of environmental quality.

6. "Financial reporting year" means the latest consecutive twelve-month period for which any of
the following reports used to support a financial test is prepared:
a. A 10-K report submitted to the securities and exchange commission;
b. An annual report of tangible net worth submitted to dun and bradstreet; or
c. Annual reports submitted to the energy information administration or the rural utilities
service.
"Financial reporting year" may thus comprise a fiscal-year or a calendar-year period.
7. "Legal defense cost" is any expense that an owner or operator or provider of financial
assurance incurs in defending against claims or actions brought:
a. By the environmental protection agency or a state to require corrective action or to
recover the costs of corrective action;
b. By or on behalf of a third party for bodily injury or property damage caused by an
accidental release; or
c. By any person to enforce the terms of a financial assurance mechanism.
8. "Local government" has the meaning given this term by applicable state law. The term is
generally intended to include:
a. Counties, municipalities, townships, separately chartered and operated special districts
(including local government public transit systems and redevelopment authorities), and
independent school districts authorized as governmental bodies by state charter or
constitution; and
b. Special districts and independent school districts established by counties, municipalities,
townships, and other general purpose governments to provide essential services.
9. "Occurrence" means an accident, including continuous or repeated exposure to conditions,
which results in a release from an underground storage tank.
NOTE: This definition is intended to assist in the understanding of these rules and is not
intended either to limit the meaning of "occurrence" in a way that conflicts with standard
insurance usage or to prevent the use of other standard insurance terms in place of
"occurrence".
10. "Owner or operator", when the owner or operator are separate parties, refers to the party that
is obtaining or has obtained financial assurances.
11. "Petroleum marketing facilities" include all facilities at which petroleum is produced or refined
and all facilities from which petroleum is sold or transferred to other petroleum marketers or to
the public.
12. "Property damage" has the meaning given this term by applicable state law. This term does
not include those liabilities which, consistent with standard insurance industry practices, are
excluded from coverage in liability insurance policies for property damage. However, such
exclusions for property damage shall not include corrective action associated with releases
from tanks which are covered by the policy.
13. "Provider of financial assurance" means an entity that provides financial assurance to an
owner or operator of an underground storage tank through one of the mechanisms listed in

sections 33.1-24-08-85 through 33.1-24-08-97, including a guarantor, insurer, risk retention
group, surety, issuer of a letter of credit, issuer of a state-required mechanism, or a state.
14. "Substantial business relationship" means the extent of a business relationship necessary
under applicable state law to make a guarantee contract issued incident to that relationship
valid and enforceable. A guarantee contract is issued "incident to that relationship" if it arises
from and depends on existing economic transactions between the guarantor and the owner or
operator.
15. "Substantial governmental relationship" means the extent of a governmental relationship
necessary under applicable state law to make an added guarantee contract issued incident to
that relationship valid and enforceable. A guarantee contract is insured incident to that
relationship if it arises from a clear commonality of interest in the event of an underground
storage tank release, such as coterminous boundaries, overlapping constituencies, common
ground water aquifer, or other relationship other than monetary compensation that provides a
motivation for the guarantor to provide a guarantee.
16. "Tangible net worth" means the tangible assets that remain after deducting liabilities, such
assets do not include intangibles such as goodwill and rights to patents or royalties. For
purposes of this definition, "assets" means all existing and all probable future economic
benefits obtained or controlled by a particular entity as a result of past transactions.
17. "Termination" under subdivisions a and b of subsection 2 of section 33.1-24-08-87 means only
those changes that could result in a gap in coverage as where the insured has not obtained
substitute coverage or has obtained substitute coverage with a different retroactive date than
the retroactive date of the original policy.

a. Taking corrective action;
b. Compensating third parties for bodily injury and property damage caused by sudden
accidental releases; or
c. Compensating third parties for bodily injury and property damage caused by nonsudden
accidental releases, the amount of assurance provided by each mechanism, or
combination of mechanisms must be in the full amount specified in subsections 1 and 2.
5. If an owner or operator uses separate mechanisms or separate combinations of mechanisms
to demonstrate financial responsibility for different petroleum underground storage tanks, the
annual aggregate required must be based on the number of tanks covered by each such
separate mechanism or combination of mechanisms.
6. Owners or operators shall review the amount of aggregate assurance provided whenever
additional petroleum underground storage tanks are acquired or installed. If the number of
petroleum underground storage tanks for which assurance must be provided exceeds one
hundred, the owner or operator shall demonstrate financial responsibility in the amount of at
least two million dollars of annual aggregate assurance by the anniversary of the date on
which the mechanism demonstrating financial responsibility became effective. If assurance is
being demonstrated by a combination of mechanisms, the owner or operator shall
demonstrate financial responsibility in the amount of at least two million dollars of annual
aggregate assurance by the first-occurring effective date anniversary of any one of the
mechanisms combined (other than a financial test or guarantee) to provide assurance.
7. The amounts of assurance required under this section exclude legal defense costs.
8. The required per-occurrence and annual aggregate coverage amounts do not in any way limit
the liability of the owner or operator.

guarantee that conforms to the requirements of this section. The guarantor must be:
a. A firm that:
(1) Possesses a controlling interest in the owner or operator;
(2) Possesses a controlling interest in a firm described under paragraph 1 of
subdivision a of subsection 1; or

(3) Is controlled through stock ownership by a common parent firm that possesses a
controlling interest in the owner or operator; or
b. A firm engaged in a substantial business relationship with the owner or operator and
issuing the guarantee as an act incident to that business relationship.
2. Within one hundred twenty days of the close of each financial reporting year the guarantor
must demonstrate that it meets the financial test criteria of section 33.1-24-08-85 based on
year-end financial statements for the latest completed financial reporting year by completing
the letter from the chief financial officer described in subsection 4 of section 33.1-24-08-85
and must deliver the letter to the owner or operator. If the guarantor fails to meet the
requirements of the financial test at the end of any financial reporting year, within one hundred
twenty days of the end of that financial reporting year the guarantor shall send via certified
mail, before cancellation or nonrenewal of the guarantee, notice to the owner or operator. If
the department notifies the guarantor that the guarantor no longer meets the requirements of
the financial test of subsections 2 or 3 and 4 of section 33.1-24-08-85, the guarantor must
notify the owner or operator within ten days of receiving such notification from the department.
In both cases, the guarantee will terminate no less than one hundred twenty days after the
date the owner or operator receives the notification, as evidenced by the return receipt. The
owner or operator must obtain alternative coverage as specified in subsection 3 of section
33.1-24-08-104.

[business address].
Recitals.
(1) Guarantor meets or exceeds the financial test criteria of subsections 2 or 3 and 4 of
section 33.1-24-08-85 and agrees to comply with the requirements for guarantors as
specified in subsection 2 of section 33.1-24-08-86.
(2) [Owner or operator] owns or operates the following underground storage tank(s) covered
by this guarantee: [List the number of tank(s) at each facility and the name(s) and
address(es) of the facility(ies) where the tanks are located. If more than one instrument is
used to assure different tanks at any one facility, for each tank covered by this
instrument, list the tank identification number provided in the notification submitted
pursuant to section 33.1-24-08-12, and the name and address of the facility. This
guarantee satisfies sections 33.1-24-08-80 through 33.1-24-08-106 requirements for

to fulfill the conditions described above.

Upon notification by the department that the Principal has failed to provide alternate financial
assurance within sixty days after the date the notice of cancellation is received by the Principal
from the Surety(ies) and that the department has determined or suspects that a release has
occurred, the Surety(ies) shall place funds in an amount not exceeding the annual aggregate
penal sum into the standby trust fund as directed by the department under section
33.1-24-08-102.
The Surety(ies) hereby waive(s) notification of amendments to applicable laws, statutes, rules,
and regulations and agrees that no such amendment shall in any way alleviate its(their)
obligation on this bond.
The liability of the Surety(ies) shall not be discharged by any payment or succession of
payments hereunder, unless and until such payment or payments shall amount in the annual
aggregate to the penal sum shown on the face of the bond, but in no event shall the obligation
of the Surety(ies) hereunder exceed the amount of said annual aggregate penal sum.
The Surety(ies) may cancel the bond by sending notice of cancellation by certified mail to the

obligations, with a Moody's rating of Aaa, Aa, A, or Baa, or a Standard and Poor's rating of
AAA, AA, A, or BBB. Where a local government has multiple outstanding issues, or where a
local government's bonds are rated by both Moody's and Standard and Poor's, the lowest
rating must be used to determine eligibility. Bonds that are backed by credit enhancement
other than municipal bond insurance may not be considered in determining the amount of

outstanding issue or issues of revenue bonds of one million dollars or more, excluding
refunded issues and by also having a Moody's rating of Aaa, Aa, A, or Baa, or a Standard and
Poor's rating of AAA, AA, A, or BBB as the lowest rating for any rated revenue bond issued by

outstanding.

### § 33.1-24-08-96. Local government guarantee.

1. A local government owner or operator may satisfy the requirements of section 33.1-24-08-83
by obtaining a guarantee that conforms to the requirements of this section. The guarantor
must be either the estate in which the local government owner or operator is located or a local
government having a "substantial governmental relationship" with the owner and operator and
issuing the guarantee as an act incident to that relationship. A local government acting as the
guarantor must:
a. Demonstrate that it meets the bond rating test requirement of section 33.1-24-08-94 and
deliver a copy of the chief financial officer's letter as contained in subsections 4 and 5 of
section 33.1-24-08-94 to the local government owner or operator.
b. Demonstrate that it meets the worksheet test requirements of section 33.1-24-08-95 and
deliver a copy of the chief financial officer's letter as contained in subsection 3 of section
33.1-24-08-95.
c. Demonstrate that it meets the local government fund requirements of subsection 1, 2,
or 3 of section 33.1-24-08-97, and deliver a copy of the chief financial officer's letter as
contained in section 33.1-24-08-97 to the local government owner or operator.
2. If the local government guarantor is unable to demonstrate financial assurance under sections
33.1-24-08-94, 33.1-24-08-95, subsection 1 of section 33.1-24-08-97, subsection 2 of section
33.1-24-08-97, or subsection 3 of section 33.1-24-08-97, at the end of the financial reporting
year, the guarantor shall send by certified mail, before cancellation or nonrenewal of the
guarantee, notice to the owner or operator. The guarantee will terminate no less than
one hundred twenty days after the date the owner or operator receives the notification, as
evidenced by the return receipt. The owner or operator must obtain alternative coverage as
specified in subsection 5 of section 33.1-24-08-104.
3. The guarantee agreement must be worded as specified in subsection 4 or 5, depending on
which of the following alternative guarantee arrangements is selected:
a. If, in the default or incapacity of the owner or operator, the guarantor guarantees to fund
a standby trust as directed by the department, the guarantee shall be worded as
specified in subsection 4.
b. If in the default or incapacity of the owner or operator, the guarantor guarantees to make
payments as directed by the department for taking corrective action or compensating
third parties for bodily injury and property damage, the guarantee shall be worded as
specified in subsection 5.

4. If the guarantor is a state, the local government guarantee with standby trust must be worded
exactly as follows, except that instructions in brackets are to be replaced with relevant
information and the brackets deleted:

amount not to exceed the coverage limits specified above.
If [owner or operator] fails to satisfy a judgment or award based on a determination of
liability for bodily injury or property damage to third parties caused by ["sudden" and/or
"nonsudden"] accidental releases arising from the operation of the above-identified tank
or tanks, or fails to pay an amount agreed to in settlement of a claim arising from or

involuntary proceeding under Title 11 (Bankruptcy) United States Code naming guarantor

except that guarantor may cancel this guarantee by sending notice by certified mail to

twenty days after receipt of such notice by [owner or operator], as evidenced by the

direct result of a release from a petroleum underground storage tank; or
(e) Bodily injury or property damage for which [insert: owner or operator] is obligated to
pay damages by reason of the assumption of liability in a contract or agreement
other than a contract or agreement entered into to meet the requirements of section
33.1-24-08-83.
(8) Guarantor expressly waives notice of acceptance of this guarantee by department, by
any or all third parties, or by [local government owner or operator].
I hereby certify that the wording of this guarantee is identical to the wording specified in

### § 33.1-24-08-97. Local government fund.

A local government owner or operator may satisfy the requirements of section 33.1-24-08-83
establishing a dedicated fund account that conforms to the requirements of this section. Except as
specified in subsection 2, a dedicated fund may not be commingled with other funds or otherwise used
in normal operations. A dedicated fund will be considered eligible if it meets one of the following
requirements:
1. The fund is dedicated by state constitutional provision, or local government statute, charter,
ordinance, or order to pay for taking corrective action and for compensating third parties for
bodily injury and property damage caused by accidental releases arising from the operation of
petroleum underground storage tanks and is funded for the full amount of coverage required
under section 33.1-24-08-83 or funded for part of the required amount of coverage and used
in combination with other mechanism or mechanisms that provide the remaining coverage.
2. The fund is dedicated by state constitutional provision, or local government statute, charter,
ordinance, or order as a contingency fund for general emergencies, including taking corrective
action and compensating third parties for bodily injury and property damage caused by
accidental releases arising from the operation of petroleum underground storage tanks, and is
funded for five times the full amount of coverage required under section 33.1-24-08-83, or
funded for part of the required amount of coverage and used in combination with other
mechanisms that provide the remaining coverage. If the fund is funded for less than five times
the amount of coverage required under section 33.1-24-08-83, the amount of financial
responsibility demonstrated by the fund may not exceed one-fifth the amount in the fund.
3. The fund is dedicated by state constitutional provision, or local government statute, charter,
ordinance, or order to pay for taking corrective action and for compensating third parties for
bodily injury and property damage caused by accidental releases arising from the operation of
petroleum underground storage tanks. A payment is made to the fund once every year for
seven years until the fund is fully funded. This seven-year period is hereafter referred to as the
"pay-in-period". The amount of each payment must be determined by this formula:

Where TF is the total required financial assurance for the owner or operator, CF is the current
amount in the fund, and Y is the number of years remaining in the pay-in-period, and:
a. The local government owner or operator has available bonding authority, approved
through voter referendum (if such approval is necessary prior to the issuance of bonds),
for an amount equal to the difference between the required amount of coverage and the
amount held in the dedicated fund. This bonding authority shall be available for taking
corrective action and for compensating third parties for bodily injury and property damage
caused by accidental releases arising from the operation of petroleum underground
storage tanks; or
b. The local government owner or operator has a letter signed by the appropriate state
attorney general stating that the use of the bonding authority will not increase the local
government's debt beyond the legal debt ceilings established by the relevant state laws.
The letter must also state that prior voter approval is not necessary before use of the
bonding authority.
4. To demonstrate that it meets the requirements of the local government fund, the chief financial
officer of the local government owner or operator or guarantor, or both, must sign a letter
worded exactly as follows, except that the instructions in brackets are to be replaced by the
relevant information and the brackets deleted:
I am the chief financial officer of [insert: name and address of local government owner or
operator, or guarantor]. This letter is in support of the use of the local government fund
mechanism to demonstrate financial responsibility for [insert: "taking corrective action" and/or
"compensating third parties for bodily injury and property damage"] caused by [insert: "sudden
accidental releases" or "nonsudden accidental releases" or "accidental releases"] in the
amount of at least [insert: dollar amount] per occurrence and [insert: dollar amount] annual
aggregate arising from operating (an) underground storage tank(s).
Underground storage tanks at the following facilities are assured by this local government
fund mechanism: [list for each facility: the name and address of the facility where tanks are
assured by the local government fund].
[Insert: "The local government fund is funded for the full amount of coverage required under
section 33.1-24-08-83, or funded for part of the required amount of coverage and used in
combination with other mechanism(s) that provide the remaining coverage", or "The local
government fund is funded for five times the full amount of coverage required under section
33.1-24-08-83, or funded for part of the required amount of coverage and used in combination
with other mechanism(s) that provide the remaining coverage", or "A payment is made to the
fund once every year for seven years until the fund is fully funded and [name of local
government owner or operator] has available bonding authority, approved through voter
referendum, of an amount equal to the difference between the required amount of coverage
and the amount held in the dedicated fund" or "A payment is made to the fund once every year
for seven years until the fund is fully funded and I have attached a letter signed by the state
attorney general stating that (1) the use of the bonding authority will not increase the local
government's debt beyond the legal debt ceilings established by the relevant state laws and
(2) that prior voter approval is not necessary before use of the bonding authority"].
The details of the local government fund are as follows:
Amount in fund (market value of fund at the close of last fiscal year): $__________
[if fund balance is incrementally funded as specified in subsection 3, insert:

Amount added to fund in the most recently completed fiscal year: $__________
[Number of years remaining in the pay-in-period:]
A copy of the state constitutional provision, or local government statute, charter, ordinance or
order dedicating the fund is attached.
I hereby certify that the wording of this letter is identical to the wording specified in
subsection 4 of section 33.1-24-08-97, as such rules were constituted on the date shown
immediately below:

### § 33.1-24-08-115. Definitions (lender liability).

1. "Borrower, debtor, or obligor" is a person whose underground storage tank or underground
storage tank system or facility or property on which the underground storage tank or
underground storage tank system is located is encumbered by a security interest. These
terms may be used interchangeably.
2. "Holder" is a person who, upon the effective date of this rule, or in the future, maintains indicia
of ownership, as defined in subsection 3, primarily to protect a security interest, as defined in
subdivision a of subsection 6, in a petroleum underground storage tank or underground
storage tank system or facility or property on which a petroleum underground storage tank or
underground storage tank system is located. A holder includes the initial holder (such as a
loan originator); any subsequent holder (such as a successor-in-interest or subsequent
purchaser of the security interest on the secondary market); a guarantor of an obligation,
surety, or any other person who holds ownership indicia primarily to protect a security interest;
or a receiver or other person who acts on behalf or for the benefit of a holder.
3. "Indicia of ownership" means evidence of a secured interest, evidence of an interest in a
security interest, or evidence of an interest in real or personal property securing a loan or
other obligation, including any legal or equitable title or deed to real or personal property
acquired through or incident to foreclosure. Evidence of such interests include mortgages,
deeds of trust, liens, surety bonds and guarantees of obligations, title held pursuant to a lease
financing transaction in which the lessor does not select initially the leased property
(hereinafter "lease financing transaction"), and legal or equitable title obtained pursuant to
foreclosure. Evidence of such interests also includes assignments, pledges, or other rights to
or other forms of encumbrance against property that are held primarily to protect a security
interest. A person is not required to hold title or a security interest in order to maintain indicia
of ownership.
4. "Operation" means, for purposes of this section, the use, storage, filling, or dispensing of
petroleum contained in an underground storage tank or underground storage tank system.
5. Petroleum production, refining, and marketing.
a. "Petroleum marketing" means the distribution, transfer, or sale of petroleum or petroleum
products for wholesale or retail purposes.
b. "Petroleum production" means the production of crude oil or other forms of petroleum, as
defined in section 33.1-24-08-03, as well as the production of petroleum products from
purchased materials.
c. "Petroleum refining" means the cracking, distillation, separation, conversion, upgrading,
and finishing of refined petroleum or petroleum products.
6. "Primarily to protect a security interest" means that the holder's indicia of ownership are held
primarily for the purpose of securing payment or performance of an obligation.
a. "Primarily to protect a security interest", as used in sections 33.1-24-08-115 through
33.1-24-08-130, does not include indicia of ownership held primarily for investment

purposes, nor ownership indicia held primarily for purposes other than as protection for a
security interest. A holder may have other, secondary reasons for maintaining indicia of
ownership, but the primary reason why any ownership indicia are held must be as
protection for a security interest.
b. "Security interest" means an interest in a petroleum underground storage tank or
underground storage tank system or in the facility or property on which a petroleum
underground storage tank or underground storage tank system is located, created, or
established for the purpose of securing a loan or other obligation. Security interests
include mortgages, deeds of trusts, liens, and title pursuant to lease financing
transactions. Security interests may also arise from transactions such as sale and
leasebacks, conditional sales, installment sales, trust receipt transactions, certain
assignments, factoring agreements, accounts receivable financing arrangements, and
consignments, if the transaction creates or establishes an interest in an underground
storage tank or underground storage tank system or in the facility or property on which
the underground storage tank or underground storage tank system is located, for the
purpose of securing a loan or other obligation.

### § 33.1-24-08-120. Participation in management (lender liability).

The term "participating in the management of an underground storage tank or underground storage
tank system" means that, subsequent to December 6, 1995, the holder was engaging in
decisionmaking control of, or activities related to, operation of the underground storage tank or
underground storage tank system, as defined herein.
1. Actions that are participation in management.
a. Participation in the management of an underground storage tank or underground storage
tank system means, for purposes of sections 33.1-24-08-115 through 33.1-24-08-130,
actual participation by the holder in the management or control of decisionmaking related
to the operation of an underground storage tank or underground storage tank system.
Participation in management does not include the mere capacity or ability to influence or
the unexercised right to control underground storage tank or underground storage tank
system operations. A holder is participating in the management of the underground
storage tank or underground storage tank system only if the holder either:

(1) Exercises decisionmaking control over the operational (as opposed to financial or
administrative) aspects of the underground storage tank or underground storage
tank system, such that the holder has undertaken responsibility for all or
substantially all of the management of the underground storage tank or
underground storage tank system; or
(2) Exercises control at a level comparable to that of a manager of the borrower's
enterprise, such that the holder has assumed or manifested responsibility for the
overall management of the enterprise encompassing the day-to-day decisionmaking
of the enterprise with respect to all, or substantially all, of the operational (as
opposed to financial or administrative) aspects of the enterprise.
b. Operational aspects of the enterprise relate to the use, storage, filling, or dispensing of
petroleum contained in an underground storage tank or underground storage tank
system, and include functions such as that of a facility or plant manager, operations
manager, chief operating officer, or chief executive officer. Financial or administrative
aspects include functions such as that of a credit manager, personnel manager,
controller, chief financial officer, or similar functions. Operational aspects of the enterprise
do not include the financial or administrative aspects of the enterprise, or actions
associated with environmental compliance, or actions undertaken voluntarily to protect
the environment in accordance with applicable requirements in chapter 33.1-24-08.
2. Actions that are not participation in management preforeclosure.
a. Actions at the inception of the loan or other transaction. No act or omission prior to the
time that indicia of ownership are held primarily to protect a security interest constitutes
evidence of participation in management within the meaning of sections 33.1-24-08-115
through 33.1-24-08-130. A prospective holder who undertakes or requires an
environmental investigation (which could include one or more of the following: a site
assessment, inspection, or audit) of the underground storage tank or underground
storage tank system or facility or property on which the underground storage tank or
underground storage tank system is located (in which indicia of ownership are to be
held), or requires a prospective borrower to clean up contamination from the
underground storage tank or underground storage tank system or to comply or come into
compliance (whether prior or subsequent to the time that indicia of ownership are held
primarily to protect a security interest) with any applicable law or regulation, is not by
such action considered to be participating in the management of the underground
storage tank or underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located.
b. Loan policing and work out. Actions that are consistent with holding ownership indicia
primarily to protect a security interest do not constitute participation in management for
purposes of sections 33.1-24-08-115 through 33.1-24-08-130. The authority for the
holder to take such actions may, but need not, be contained in contractual or other
documents specifying requirements for financial, environmental, and other warranties,
covenants, conditions, representations, or promises from the borrower. Loan policing and
work out activities cover and include all such activities up to foreclosure, exclusive of any
activities that constitute participation in management.
(1) Policing the security interest or loan.
(a) A holder who engages in policing activities prior to foreclosure will remain
within the exemption provided that the holder does not together with other
actions participate in the management of the underground storage tank or
underground storage tank system as provided in subsection 1. Such policing
actions include requiring the borrower to clean up contamination from the

underground storage tank or underground storage tank system during the term
of the security interest; requiring the borrower to comply or come into
compliance with applicable federal, state, and local environmental and other
laws, rules, and regulations during the term of the security interest; securing or
exercising authority to monitor or inspect the underground storage tank or
underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located
(including onsite inspections) in which indicia of ownership are maintained, or
the borrower's business or financial condition during the term of the security
interest; or taking other actions to adequately police the loan or security
interest (such as requiring a borrower to comply with any warranties,
covenants, conditions, representations, or promises from the borrower).
(b) Policing activities also include undertaking by the holder of underground
storage tank environmental compliance actions and voluntary environmental
actions taken in compliance with chapter 33.1-24-08, provided that the holder
does not otherwise participate in the management or daily operation of the
underground storage tank or underground storage tank system as provided in
subsection 1 of section 33.1-24-08-120 and section 33.1-24-08-130. Such
allowable actions include release detection and release reporting, release
response and corrective action, temporary or permanent closure of an
underground storage tank or underground storage tank system, underground
storage tank upgrading or replacement, and maintenance of corrosion
protection. A holder who undertakes these actions must do so in compliance
with the applicable requirements in chapter 33.1-24-08. A holder may directly
oversee these environmental compliance actions and voluntary environmental
actions, and directly hire contractors to perform the work, and is not by such
action considered to be participating in the management of the underground
storage tank or underground storage tank system.
(2) Loan work out. A holder who engages in work out activities prior to foreclosure will
remain within the exemption provided that the holder does not together with other
actions participate in the management of the underground storage tank or
underground storage tank system as provided in subsection 1. For purposes of this
rule, "work out" refers to those actions by which a holder, at any time prior to
foreclosure, seeks to prevent, cure, or mitigate a default by the borrower or obligor;
or to preserve, or prevent the diminution of, the value of the security. Work out
activities include restructuring or renegotiating the terms of the security interest;
requiring payment of additional rent or interest; exercising forbearance; requiring or
exercising rights pursuant to an assignment of accounts or other amounts owing to
an obligor; requiring or exercising rights pursuant to an escrow agreement
pertaining to amounts owing to an obligor; providing specific or general financial or
other advice, suggestions, counseling, or guidance; and exercising any right or
remedy the holder is entitled to by law or under any warranties, covenants,
conditions, representations, or promises from the borrower.
3. Foreclosure on an underground storage tank or underground storage tank system or facility or
property on which an underground storage tank or underground storage tank system is
located, and participation in management activities postforeclosure.
a. Foreclosure.
(1) Indicia of ownership that are held primarily to protect a security interest include legal
or equitable title or deed to real or personal property acquired through or incident to
foreclosure. For purposes of sections 33.1-24-08-115 through 33.1-24-08-130, the

term "foreclosure" means that legal, marketable, or equitable title or deed has been
issued, approved, and recorded, and that the holder has obtained access to the
underground storage tank, or underground storage tank system, underground
storage tank facility, and property on which the underground storage tank or
underground storage tank system is located, provided that the holder acted
diligently to acquire marketable title or deed and to gain access to the underground
storage tank, underground storage tank system, underground storage tank facility,
and property on which the underground storage tank or underground storage tank
system is located. The indicia of ownership held after foreclosure continue to be
maintained primarily as protection for a security interest provided that the holder
undertakes to sell, release an underground storage tank or underground storage
tank system or facility or property on which the underground storage tank or
underground storage tank system is located, held pursuant to a lease financing
transaction (whether by a new lease financing transaction or substitution of the
lessee), or otherwise divest itself of the underground storage tank or underground
storage tank system or facility or property on which the underground storage tank or
underground storage tank system or facility or property on which the underground
storage tank or underground storage tank system is located, in a reasonably
expeditious manner, using whatever commercially reasonable means are relevant
or appropriate with respect to the underground storage tank or underground storage
tank system or facility or property on which the underground storage tank or
underground storage tank system is located, taking all facts and circumstances into
consideration, and provided that the holder does not participate in management as
defined in subsection 1 prior to or after foreclosure.
(2) For purposes of establishing that a holder is seeking to sell, release pursuant to a
lease financing transaction (whether by a new lease financing transaction or
substitution of the lessee), or divest in a reasonably expeditious manner an
underground storage tank or underground storage tank system or facility or property
on which the underground storage tank or underground storage tank system is
located, the holder may use whatever commercially reasonable means as are
relevant or appropriate with respect to the underground storage tank or
underground storage tank system or facility or property on which the underground
storage tank or underground storage tank system is located, or may employ the
means specified in subdivision b of subsection 3. A holder that outbids, rejects, or
fails to act upon a written bona fide, firm offer of fair consideration for the
underground storage tank or underground storage tank system or facility or property
on which the underground storage tank or underground storage tank system is
located, as provided in subdivision b of subsection 3, is not considered to hold
indicia of ownership primarily to protect a security interest.
b. Holding foreclosed property for disposition and liquidation. A holder, who does not
participate in management prior to or after foreclosure, may sell, release, pursuant to a
lease financing transaction (whether by a new lease financing transaction or substitution
of the lessee), an underground storage tank or underground storage tank system or
facility or property on which the underground storage tank or underground storage tank
system is located, liquidate, wind up operations, and take measures, prior to sale or other
disposition, to preserve, protect, or prepare the secured underground storage tank or
underground storage tank system or facility or property on which the underground
storage tank or underground storage tank system is located. A holder may also arrange
for an existing or new operator to continue or initiate operation of the underground
storage tank or underground storage tank system. The holder may conduct these
activities without voiding the security interest exemption, subject to the requirements of
sections 33.1-24-08-115 through 33.1-24-08-130.

(1) A holder establishes that the ownership indicia maintained after foreclosure continue
to be held primarily to protect a security interest by, within twelve months following
foreclosure, listing the underground storage tank or underground storage tank
system or the facility or property on which the underground storage tank or
underground storage tank system is located, with a broker, dealer, or agent who
deals with the type of property in question, or by advertising the underground
storage tank or underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located, as being
for sale or disposition on at least a monthly basis in either a real estate publication
or a traded or other publication suitable for the underground storage tank or
underground storage tank system or facility or property on which the underground
storage tank or underground storage tank system is located, or a newspaper of
general circulation (defined as one with a circulation more than ten thousand, or one
suitable under any applicable federal, state, or local rules of court for publication
required by court order or rules of civil procedure) covering the location of the
underground storage tank or underground storage tank system or facility or property
on which the underground storage tank or underground storage tank system is
located. For purposes of this provision, the twelve-month period begins to run from
December 6, 1995, or from the date that the marketable title or deed has been
issued, approved and recorded, and the holder has obtained access to the
underground storage tank or underground storage tank system, underground
storage tank facility and property on which the underground storage tank or
underground storage tank system is located, whichever is later, provided that the
holder acted diligently to acquire marketable title or deed and to obtain access to
the underground storage tank or underground storage tank system, underground
storage tank facility and property on which the underground storage tank or
underground storage tank system is located. If the holder fails to act diligently to
acquire marketable title or deed or to gain access to the underground storage tank
or underground storage tank system, the twelve-month period begins to run from
December 6, 1995, or from the date on which the holder first acquires either title to
or possession of the secured underground storage tank or underground storage
tank system, or facility or property on which the underground storage tank or
underground storage tank system is located, whichever is later.
(2) A holder that outbids, rejects, or fails to act upon an offer of fair consideration for the
underground storage tank or underground storage tank system or the facility or
property on which the underground storage tank or underground storage tank
system is located, establishes by such outbidding, rejection, or failure to act, that the
ownership indicia in the secured underground storage tank or underground storage
tank system or facility or property on which the underground storage tank or
underground storage tank system is located are not held primarily to protect the
security interest, unless the holder is required, in order to avoid liability under
federal or state law, to make a higher bid, to obtain a higher offer, or to seek or
obtain an offer in a different manner.
(a) Fair consideration, in the case of a holder maintaining indicia of ownership
primarily to protect a senior security interest in the underground storage tank or
underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located, is
the value of the security interest as defined in this section. The value of the
security interest includes all debt and costs incurred by the security interest
holder, and is calculated as an amount equal to or in excess of the sum of the
outstanding principal (or comparable amount in the case of a lease that
constitutes a security interest) owed to the holder immediately preceding the
acquisition of full title (or possession in the case of a lease financing

transaction) pursuant to foreclosure, plus any unpaid interest, rent, or penalties
(whether arising before or after foreclosure). The value of the security interest
also includes all reasonable and necessary costs, fees, or other charges
incurred by the holder incident to work out, foreclosure, retention, preserving,
protecting, and preparing, prior to sale, the underground storage tank or
underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located,
release, pursuant to a lease financing transaction (whether by a new lease
financing transaction or substitution of the lessee), of an underground storage
tank or underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located, or
other disposition. The value of the security interest also includes environmental
investigation costs (which could include one or more of the following: a site
assessment, inspection, or audit of the underground storage tank or
underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located), and
corrective action costs incurred under sections 33.1-24-08-41 through
33.1-24-08-57, or any other costs incurred as a result of reasonable efforts to
comply with any other applicable federal, state, or local law or regulation; less
any amounts received by the holder in connection with any partial disposition
of the property and any amounts paid by the borrower (if not already applied to
the borrower's obligations) subsequent to the acquisition of full title (or
possession in the case of a lease financing transaction) pursuant to
foreclosure. In the case of a holder maintaining indicia of ownership primarily
to protect a junior security interest, fair consideration is the value of all
outstanding higher priority security interests plus the value of the security
interest held by the junior holder, each calculated as set forth in this
subparagraph.
(b) Outbids, rejects, or fails to act upon an offer of fair consideration means that
the holder outbids, rejects, or fails to act upon within ninety days of receipt, a
written, bona fide, firm offer of fair consideration for the underground storage
tank or underground storage tank system or facility or property on which the
underground storage tank or underground storage tank system is located
received at any time after six months following foreclosure, as defined in
subsection 3. A "written, bona fide, firm offer" means a legally enforceable,
commercially reasonable, cash offer solely for the foreclosed underground
storage tank or underground storage tank system or facility or property on
which the underground storage tank or underground storage tank system is
located, including all material terms of the transaction, from a ready, willing,
and able purchaser who demonstrates to the holder's satisfaction the ability to
perform. For purposes of this provision, the six-month period begins to run
from December 6, 1995, or from the date that marketable title or deed has
been issued, approved and recorded to the holder, and the holder has
obtained access to the underground storage tank or underground storage tank
system, underground storage tank facility and property on which the
underground storage tank or underground storage tank system is located,
whichever is later, provided that the holder was acting diligently to acquire
marketable title or deed or to gain access to the underground storage tank or
underground storage tank system, underground storage tank facility and
property on which the underground storage tank or underground storage tank
system is located. If the holder fails to act diligently to acquire marketable title
or deed or to gain access to the underground storage tank or underground
storage tank system, the six-month period begins to run from December 6,

1995, or from the date on which the holder first acquires either title to or
possession of the secured underground storage tank or underground storage
tank system, or facility or property on which the underground storage tank or
underground storage tank system is located, whichever is later.
c. Actions that are not participation in management postforeclosure. A holder is not
considered to be participating in the management of an underground storage tank or
underground storage tank system or facility or property on which the underground
storage tank or underground storage tank system is located when undertaking actions
under chapter 33.1-24-08, provided that the holder does not otherwise participate in the
management or daily operation of the underground storage tank or underground storage
tank system as provided in subsection 1 of section 33.1-24-08-120 and section
### § 33.1-24-08-130. Such allowable actions include release detection and release reporting,

release response and corrective action, temporary or permanent closure of the
underground storage tank or underground storage tank system, underground storage
tank upgrading or replacement, and maintenance of corrosion protection. A holder who
undertakes these actions must do so in compliance with the applicable requirements in
chapter 33.1-24-08. A holder may directly oversee these environmental compliance
actions and voluntary environmental actions, and directly hire contractors to perform the
work, and is not by such action considered to be participating in the management of the
underground storage tank or underground storage tank system.

### § 33.1-24-08-130. Operating an underground storage tank or underground storage tank

system (lender liability).
1. Operating an underground storage tank or underground storage tank system prior to
foreclosure. A holder, prior to foreclosure, as defined in subsection 3 of section
33.1-24-08-120, is not an "operator" of a petroleum underground storage tank or underground
storage tank system for purposes of compliance with the underground storage tank technical
standards as defined in section 33.1-24-08-115, the underground storage tank corrective
action requirements under sections 33.1-24-08-41 through 33.1-24-08-57, and the
underground storage tank financial responsibility requirements under sections 33.1-24-08-80
through 33.1-24-08-101, provided that, after December 6, 1995, the holder is not in control of
or does not have responsibility for the daily operation of the underground storage tank or
underground storage tank system.
2. Operating an underground storage tank or underground storage tank system after foreclosure.
The following provisions apply to a holder who, through foreclosure, as defined in
subsection 3 of section 33.1-24-08-120, acquires a petroleum underground storage tank or
underground storage tank system or facility or property on which a petroleum underground
storage tank or underground storage tank system is located.
a. A holder is not an "operator" of a petroleum underground storage tank or underground
storage tank system for purposes of compliance with chapter 33.1-24-08 if there is an
operator, other than the holder, who is in control of or has responsibility for the daily
operation of the underground storage tank or underground storage tank system, and who
can be held responsible for compliance with applicable requirements of chapter
33.1-24-08.
b. If another operator does not exist, as provided for under subdivision a, a holder is not an
"operator" of the underground storage tank or underground storage tank system, for
purposes of compliance with the underground storage tank technical standards as
defined in section 33.1-24-08-115, the underground storage tank corrective action
requirements under sections 33.1-24-08-41 through 33.1-24-08-57, and the underground
storage tank financial responsibility requirements under sections 33.1-24-08-80 through
