The Board of Health may require the owner of any existing tank to have it and its piping tested, at the owner's expense, in any case in which the owner has failed to make timely application for a permit as required under § 170-5.
I. 
Except for testing performed on a tank and its piping prior to their being covered, a tank shall be tested by any final or precision test, such as the Kent-Moore Pressure Test or equivalent, not involving air pressure, that can accurately detect a leak of 0.05 gallon per hour or less, after adjustment for relevant variables such as temperature change and tank end deflection, and that is approved by the State Fire Marshal. Piping shall be tested hydrostatically to 150% of the maximum anticipated pressure of the system.
J. 
All tests shall be administered by qualified persons approved by the Board of Health, and any such person shall notify the Board of Health and Fire Chief prior to administering a test.
K. 
The person performing any test under this section shall promptly supply the owner, the Board of Health and the Fire Chief with certified copies of all test results for a tank and its piping. The Board shall keep its copy with the records of that storage facility.
A. 
In the event of a leak, whether determined by testing or otherwise, the following steps shall be taken:
(1) 
The operator shall immediately notify the owner, the Fire Chief and the Office of Incident Response of the Department of Environmental Protection (OIR-DEP).
(2) 
The owner shall promptly verify that the Fire Chief and OIR-DEP have been notified and shall notify the Board of Health.
(3) 
If testing has confirmed that the source of the leak is the piping for a particular tank, the operator shall take that tank out of service immediately.
(4) 
If testing has confirmed that the source of the leak is a particular tank, the operator shall within 24 hours cause the entire storage facility to be emptied of its product.
(5) 
If testing has failed to determine the source of the leak within a storage facility, the operator shall within 24 hours cause the entire storage facility to be emptied of its product.
B. 
Until the arrival of a representative of OIR-DEP, the Fire Chief shall take charge of all emergency containment procedures and shall verify that all steps required under Subsection A have been taken.
C. 
The owner, the Fire Chief and the Board of Health shall cooperate with OIR-DEP in all efforts to identify the source of the leak, to contain it, and to restore the environment, including any groundwater or surface water that may have been contaminated by the leak, to a condition and quality acceptable to DEP.
D. 
The Board of Health shall determine whether any tank or its components that have been identified as the source of a leak shall be removed and replaced with a double-walled tank, and shall notify the owner and the Fire Chief of its decision.
E. 
If the Board permits the repair of any leaking tank, the Board shall require that the tank and its piping be tested, at the owner's expense and in accordance with the provisions of § 170-9I and J, prior to being restored to service, at two-year intervals for 10 years and annually thereafter.
F. 
Any repair of a tank or replacement or repair of components shall be performed by qualified technicians, following the manufacturer's directions, and, in the case of relining of a steel tank, following the recommendations of American Petroleum Institute Publication #1631, First Edition, 1983, or any subsequent edition as it may appear.
G. 
If the Board of Health determines that a tank and its components shall be removed, the owner shall first obtain a permit from the Fire Chief, pursuant to MGL c. 21O, § 1, as amended. Any removal shall be completed within 14 calendar days after the Board of Health has notified the owner of its decision.
H. 
The owner shall be responsible for all costs of reclaiming, recovering and properly disposing of any product that has leaked and for all costs of restoring the environment, including any groundwater or surface water that has been contaminated, to a condition and quality acceptable to DEP.
A. 
If the owner of a tank which either is located under a building and cannot be removed from the ground without first removing the building or is so located that it cannot be removed from the ground without endangering the structural integrity of another tank decides to abandon it, the owner shall promptly notify the Fire Chief and the Board of Health of this decision and, subject to the directions of the Fire Chief, have all the product removed from the tank, by hand pump if necessary, and the tank cleaned and purged and filled with slurry concrete only.
B. 
Except as provided in Subsection A, no tank may be abandoned in place. Any owner of a tank who has decided to abandon it and any owner of a tank that has in fact been out of service for a period of time constituting abandonment, as defined in § 170-2, shall immediately obtain a permit from the Fire Chief pursuant to MGL c. 21O, § 1, as amended, and, subject to the directions of the Fire Chief, have any product removed from the tank, all tank openings properly secured and the tank removed from the ground. The product and tank shall be disposed of, at the owner's expense, as directed by the Fire Chief.
C. 
The owner of a tank which is licensed under MGL Chapter 21O, as amended, and which the owner has decided to take out of service for a period of less than six months, shall promptly notify the Fire Chief and the Board of Health of the decision and, subject to the directions of the Fire Chief, have all the product removed from the tank and disposed of as directed by the Fire Chief, all tank openings properly secured, and the tank filled with water. Before any such tank may be restored to service, the owner shall notify the Fire Chief and the Board of Health, and have the water removed and disposed of in a manner approved by DEP. The Board of Health may require that the owner have the tank and its piping tested, at the owner's expense, in accordance with the provisions of § 170-9I and J.
A. 
Each day during which such violation continues shall constitute a separate offense. This bylaw may be enforced pursuant to MGL c. 40, § 21D, as amended, by a local police officer or any other officer having police powers. Upon request of the Board of Health, the Select Board, Town Counsel shall take such legal action as may be necessary to enforce this bylaw.
B. 
In the event of any violation of this bylaw by the owner or operator of a storage facility, the Board of Health, instead of or in addition to requesting enforcement under Subsection A, may revoke or suspend the owner's permit or may require more frequent testing than would otherwise be required under § 170-9; and if a permit is revoked or if a storage facility has been installed or maintained without a permit, the Board may order that the storage facility be removed from the ground. Before revoking or suspending an owner's permit, or requiring removal of a storage facility from the ground, the Board shall hold a public hearing on the proposed action; shall give the owner at least 14 calendar days' notice of the hearing by certified mail and shall make its decision in writing with a brief statement of the reasons for its decision.
The Board of Health may, after a public hearing, vary the application of any provision of this bylaw, unless otherwise required by law, when, in its opinion, the applicant has demonstrated that an equivalent degree of protection will still be provided to public and private water supplies. Notice of the hearing shall be given by the Board, at the applicant's expense, at least 14 calendar days prior thereto, by certified mail to all abutters to the property at which the owner's storage facility is located and by publication in a newspaper of general circulation in the Town or city. The notice shall include a statement of the variance sought and the reasons therefor. Any grant or denial of a variance shall be in writing and shall contain a brief statement of the reasons for the grant or denial.
The invalidity of any provision of this bylaw shall not affect the validity of the remainder.
