The Department of Environmental Services (DES) established rules
for registration and permitting in November 1985, as well as:
-
standards for design,
-
installation,
-
operation,
-
maintenance, and
-
monitoring of UST facilities.
These rules apply to:
-
all underground storage tank systems that store motor fuels or a regulated substance other then heating oil having a total storage capacity of more than 110 gallons, and
-
non-residential tank systems having an on-premise use heating oil storage
capacity of more than 1,100 gallons.
The owner of an underground storage facility must register
the facility with DES by providing the information required in UST
facility rules. Owners are required to submit in writing any change
in facility status, such as, ownership and equipment within 10 days of
the change. No person is allowed to operate a facility, which is
not registered with the department.
The owner of a UST facility must provide an application
and plans to DES before:
-
commencing construction,
-
installation of a new or replacement system, or
-
a substantial modification of an existing underground storage system,.
 |
The plans must be prepared and stamped by a registered professional
engineer, licensed to practice in the state of New Hampshire. |
 |
Notification to DES of the completion of the installation is made at
least 5 days prior to backfilling the tank top and/or piping, to arrange
for an inspection and a letter prepared and stamped by the engineer shall
be submitted to DES stating that the construction has been performed in
accordance with the approved plans. |
The new system shall not be backfilled or placed into service until
DES determines that the system meets the rules for a new UST system.
DES must be notified within 30 days prior to any scheduled system closure.
An assessment must be completed
and results sent to DES to determine if any contamination is present.
