Leak Check Procedures and Requirements
Cite as 19 Miss. Admin. Code Pt. 7, R. 14.04
Leak Check Procedures and Requirements
A. Leak Checks shall be performed on any interruption of service to an existing system or
first time service of a new customer.
B. Any method used for performing a leak check should be sufficient to actually find a leak
if one exists. Suggested methods for performing a Leak Check include the proper use of
lights, the use of a gas meter, and checks performed not using a gas meter, as set forth in
NFPA-54.
C. Leak Checks performed in occupied dwellings shall include an interior inspection of the
propane system and appliances, and the reigniting pilots and appliances to assure proper
operation of appliances.
D. In the event that a leak is detected in a system, which will not be immediately repaired,
then a “lockout” of the system shall be implemented at the service valve until the
necessary repairs may be completed for the safe operation of the system. Lockout shall
be required regardless of whether the system components are owned by the propane
provider or the customer.
E. Documentation of Leak Checks, including the items checked and the results of the check
shall be kept on file at the branch or office serving the customer and must be made
available to Mississippi LC Gas Inspectors upon request. It is recommended that the
customer or customer representative, who is at least 18 years old, be present at the time
the leak check is performed, and that the customer or customer representative sign the
leak check documentation.

14.05: Permitting Procedures
A. Mississippi Code § 75-57-49 sets forth the Permittee requirements, including but not limited
to the requirement for proof of good character, competency to transact business so as to
safeguard the interest of the public, and financial responsibility. Proof of financial responsibility
is complied with through the provision of Certificates of Insurance from the Permittee
establishing the existence of appropriate insurance coverage, or through provision of surety
bonds or personal bonds with appropriate conditions. The Certificates of Insurance provided
typically sets forth a period of coverage of one (1) year.
B. Before any person shall be granted a permit as a distributor or installer, either at wholesale or
retail, he shall satisfy the State Liquefied Compressed Gas Board that he has sufficient insurance
coverage as required by law and a copy of said policy shall be filed with the Liquefied
Compressed Gas Division with the application for permit, and a copy of a policy shall be filed
with the Liquefied Compressed Gas Division each year thereafter as long as the permit is in
effect. No permit shall be issued that does not have a copy of the insurance policy attached to it.
In the event coverage is cancelled or the insurer goes bankrupt or is sold, a distributor or installer
shall file evidence of new coverage and failure to do so may result in a fine or a permit being
suspended or cancelled until such time that new coverage has been obtained and proof supplied
to the Liquefied Compressed Gas Division.
C. Expiration of Permits: In order to ensure that Permittees are continually in compliance with
the financial responsibility requirements, all Permit’s issued by the LC Gas Board shall have an
expiration date equal to the last day of coverage evidenced on their most recent Certificate of
Insurance on file with the LC Gas Division of the Mississippi Insurance Department. In the
event that the Permittee has established financial responsibility through the provision of a surety
bond or a personal bond in accordance with Miss. Code § 75-57-49, then the expiration date for
the permit shall equal the end period of the obligation under the surety bond or personal bond.
D. Renewal of Permits: In the case of approved Permittees who are reaching the expiration date
of their permit, the permit shall automatically renew, without the need for action by the LC Gas
Board, upon the provision by the Permittee to the LC Gas Division of the Mississippi Insurance
Department, of a new or extended Certificate of Insurance, or surety / personal bond in
compliance with the requirements of Miss. Code § 75-57-49. The renewed permit shall have
and reflect an expiration date equal to the last day of coverage under the most current evidence
of financial responsibility.
E. Before any person, firm or corporation shall enter the Liquefied Compressed Gas business as
a distributor who plans to make retail or wholesale tank truck deliveries to consumers, and before
a permit may be granted, such person, firm or corporation shall locate, within the State of
Mississippi, a propane storage container of not less than 14,000 water gallons capacity and an
aggregate total of propane storage containers of not less than 30,000 water gallons capacity for
each permit granted. Before a permit is issued, a State Liquefied Compressed Gas Inspector
shall inspect the facility to verify that the required storage capacity has been met by the
applicant.
F. Any liquefied compressed gas dealer, or other person may apply to the Liquefied Compressed
Gas Board to take an examination to qualify as an installer. The test shall be sufficient to test the
knowledge of the applicant as to his qualifications for installing, repairing, altering, etc.,
equipment used in the handling of liquefied compressed gases and of his knowledge of the
handling and storage of such gases.
