Every owner of an underground fuel oil storage tank existing
on the effective date of these regulations shall register with the
Board of Health the type, size, date of original installation and
location of all underground fuel oil storage tanks on or before January
1, 1987. Every owner of any underground fuel oil storage installed
or replaced after the effective date of these regulations shall register
with the Board of Health the type, size, date of installation and

The Board of Health shall notify registered owners of underground fuel oil tanks of the date of required removal or replacement of such tanks pursuant to §

The Nantucket Board of Health hereby has the right to enter
onto private property in order to inspect and test underground fuel
oil tanks which it suspects, in its sole judgment, may pose a hazard
to public health or safety. The cost for such inspection and testing
shall be borne by the Board of Health if the tank so tested passes
the test and shall be borne by the owner of the tank if the tank fails
the test.
Following the effective date of these regulations, the installation
of fuel oil tanks shall meet or exceed one of the following specifications:
A. Basement installation. Tanks shall be installed above ground in basements
on a three-inch reinforced concrete floor or single pad. If a pad
is used, the outside dimensions of the pads shall exceed by six inches
the outside dimensions of the tank to be installed and shall include
a one-inch-high containment lip around its perimeter.
B. Above-ground outdoor installation. Tanks shall be installed above
ground outside the structure on a three-inch-thick, single, reinforced
concrete pad, the outside dimensions of which shall exceed by six
inches the outside dimensions of the tank to be installed. The tank
may be screened by a board fence meeting the requirements of the Historic
District Commission and/or the planting of a dense hedge or line of
shrubs.
C. Underground tank installation outside Aquifer Protection District. Tanks meeting or exceeding the specifications for an STI-P3 steel tank, or UL-listed seamless spherical fiberglass tanks, may be installed underground if they are located outside the Aquifer Protection District, as delineated on the Town's Zoning Map. Such tanks shall be covered by a thirty-year written warranty by the manufacturer. Underground fuel oil tanks exceeding 1,000 gallons shall comply with the periodic tank and pipe testing requirements applicable to underground gasoline tanks found in §
363-7 of these regulations.
D. Underground tank installation inside the Aquifer Protection District. Double-walled steel tanks meeting or exceeding a Type 1 UL 58 secondary containment, or double-walled UL-listed spherical fiberglass tanks, may be installed underground if they are located within the Aquifer Protection District, as delineated on the Town's Zoning Map. Such tanks shall be covered by a thirty-year written warranty by the manufacturer, and shall include a means for continuously monitoring the space between the inner and outer wall for leaks in either wall, fitted with both visual and audible alarms. Underground fuel oil tanks exceeding 1,000 gallons installed after the effective date of these regulations shall comply with the periodic tank and pipe testing requirements applicable to underground gasoline tanks found in §
