BOFl.rd of Healt.h hereby ,'ldopts following r0gulations under powers authorized Massachusetts General Laws, Chapter 111, Section 31. the b" I Section 2: Purpose Nantucket Island's sole source of drinking water is its ground water. Because of the Island's locationi2 miles at sea, there is no opportunity to pipe water tg the Island should this source be contaminated. The purpose of these regulations is to protect ground and surface waters from one potentially lethal source of contamination leaking underground fuel and chemical storage tanks. \ Section 3: Definitions CATHODIC PROTECTION means a system which inhibits the corrosion of a tank or components through either the sacrificial annode or the impressed current method of creating a corrosion-inhibiting electrical current. COHPONENTS means piping, pumps and other related storage, conveyancing and dispensing elements which are installed underground and which, together with one or more tanks and any cathodic protection or mouitoring syst.em, constitute a storage system Of facilit.y. GASOLINE m~ans any fuel which can be us~d to fuel Otto or Diesel cycle internal combustion engine. OPERATOR means the persons respons i ble facility. lessee of a storage facility for the daily operation of a or the storage OWNER means the person or persons, corpuration, t-ea1 estate trust or otiH'r similar ,?ntlty including any ()overnment entity having legal ownership of a storage facility.

Section S: Variances The Board of Health may vary the application of any provision of this regulation, unless such variance is otherwise prohibited by law, when, in the opinion of the Board, the applicant has demonstrated that an equivalent degree of ground water protection will be provided. The Board of Health shall notify all abutters to tl)e subject property by certified mail sent to their residence address as set forth in the most recent Assessor's recor~ at least ten days before the Board of Health meeting ~t which the variance will be considered advising said abutters of the variance requested and the time and place of the meeting. Any approval or denial of the variance shall be in writing and shall include findings which were the b~sis for the decision to approve or deny. The Board of' Health may include in any approval of a variance additional requirements that must be met as a condition for granting such a variance. PART B - UNDERGROU~D GASOLINE STORAGE FACILITIES Section 1: Tank Registration Every owner of an underground gasoline storage system shall register with the Board of Health the size, type, age and location of each tank, and the type of material stored, on or before June 1, 1985. Information on the date of purchase, date of installation, and evidence of the issuance of a Fire Department permit shall be provided as part of such registration. Owners of storage systems for which evidence of installation date is not available shall, by order of the Board of Hea 1 t h , ha ve such tanks tes ted or uncovered for inspection. if,}n the opinion of the Board of Health or the Fire Chief, the tank is not product tight, it shall be removed forthwith at the owner's expense.

All underg round gasol i ne stot" :Jgc tanks and pip i ng sys tems shall be subject to a Petro-Tite (Kent-Moore) or Leak Locator test, or any other State-approved test providing equivalent safety and effectiveness in the opinion of the Nantucket Board of Health. Such tests shall be conductEd prior to the tenth anniversary of the installation of the tank and annually thereafter. Air pressure tests shall not be permi t ted on tanks which have or have had petroleum product in them. The Nantucket Board of Health may postpone the testing required above for new tanks installed after the ~ffective date of these regulations until the fifth year prior to the predicted mean age to leak as established by, a method of predictabili ty analysis which is recognized by the petroleum industry and approved by the Board' of Health. The method shall be based upon, at a minimum, the following factors: soil pH, soil moisture, soil conductivity,: tank size, type of backfill, height of water table, tank depth, and the presence or absence of sulf ides in the soi ls. In no case shall the "f if th year pr ior to mean ~ge" be in excess of twenty-five years after the installation. Testing will be required annually thereafter. Section 3: Gasoline Tank Oesiqn and Installation Specifications All new or replacement gasoline tanks, and their components shall be designed and constructed in accordance wi th the following specifications in order to provide maximum protection against corrosion and leakage. 3.1 Type of 'l'ank Only the following tank systems shall be approved: a. UL-listed fiberglass-reinforced plastic (FRP) tanks. Fiberglass tanks shall be installed only by an installation contractor approved by the manufacturer of the tank. b. UL-listed steel tanks provided with cathodic protection, with a coal-tar epoxy or- urethane coating and electrical isolation, clnd equipped with a test box to measure electrical potential.

Any other "state-of-the-art" type tank construction approved by the State Fire Marshall, by the Board of Health and Fire Chief. 3.2 Striker Plates All new or replacement gasoline tanks must be equipped with a metallic or non-metallic striker plate, at least 24" X 24" in area, at least l/4" thick, and attached to the bottom of the tank under each opening. \ 3.3 Corrosion Protection All new or replacement tanks, including all) accessory components, shall be protected against corrosio~ by use of non-corrosive materials or by use of cathodic protection and electrical isolation and be compatible with the product to be stored in the facility. All cathodic protection systems shall be tested annually by a qualified person and shall have at all times a negative voltage of at least .85 vol ts, as measured by a test box, between the structure being protected and a saturated copper-copper sulfate reference electrode contacting the soil electrolyte; provided that if a zinc reference electrode is used, the negative voltage must be at least l.95 volts. These measurements shall be made with sacrificial anodes attached, or if impres~ed current is used, with the rectifier turned on. 3.4 Testing Compatability All new or replacement gasoline tanks shall be designed, constructed and installed so as to allow testing for tightness or replacement without the need for disturbing elements or the storage faci 1 i ty ulllF~r than the elements that are to be tested or replac~d.

The tank shall be tested hydrostatical).y, or by air pressure at not less than 3 nor more than 5 pounds per square inch. The piping shall be tested hydrostatically to 150 percent of the maximum anticipated pressure of the system or tested pneumatically, after all' joints and connections have been coated with soap solution, to lOO percent of the maximum anticipated pressure Ob the system, but not less than 50 pounds per square inch at\the highest point of the system. After the tank and piping have been fully covered, the area paved and the tank filled wi th product, the tank and its piping shall be again tested, separately, at the owner's expense, by any State-approved test, not involving air pressure, which is acur~te to 0.05 gallons per hour or less, after the adjustment for var iables, and which is approved by the Board' of Heal th with a certified copy of the results of all testing required by this subsection, which the Board of Health shall keep with the records for the storage facility. Section 4: Tank and Pipe Removal Effective January 1, 1988, all underground gasoline storage systems which do not meet the design specifications as set forth in Section 3 shall be removed and properly disposed of at an age of twenty years after installation. i'brD .Y~ l,~ Bernard D. ,ro,sma n.
