Borges 202 Westford Street Lowell, MA 01851 84A Sea Street _ Dear Mr.Borges: Following our meeting on the morning of April 22, 1991, 1 contacted the Boards of Health and Buildinq. Together we visited the site on the morning or April 23, 1991 to qet a final opinion on the status of your underground oil tank. The first and most important point is that there is no visible sign of an oil vent pipe. Enclosed is a copy of the laws regarding the vent pipe and its placement. (527 CMR 4.02(10) As for the tank, it is of the opinion of all agencies concerned that the location of the tank does not allow for its safe removal nor will the Board of Health allow its continued use due to the condition of its exterior. The tank cannot be vaulted safely, in the opinion of the Building Department, nor will the Fire Department allow anyone to compromise the structural integrity of the building or the surrounding fill in the interest of public safety. (See enclosures) i Mr. M. Borges Page 2 Under 527 CMR 9.21 ( 1 ), the law al lows for the abandonment of underground tanks that are considered by the Head of the Fire Department unremovable due to structural problems. These tanks are to be filled with cement and each step witnessed by the Fire Dep:-irtment. Prior to that happening, provisions must be rnade for an alternate heat/fuel source--either an aboveground oil tank.or connection to the already existing gas meter in the rear. Please contact this office for information in regards to permits, etc. Thank you. DONALD H.CHASE, JP,.,Lieutenant Fire Prevention Officer For: PAUL D.

The vent opening and vent pipe shall be of ample I size to prevent abnormal pressure in the tank during filling, at least equal to the size of the fill pipe if of a tight connection design but not smaller than one-and-one-quarter inch (1 1/4") iron pipe size for light fuel oil and not less than two-inch (2") iron pipe size for heavy fuel oil. Vent pipes from tanks may be connected into one outlet pipe. The common outlet pipe shall be at least as large as the largest individual vent i pipe connected thereto.

All vent caps on vent pipes terminating less than six (6) feet above the natural grade of the surface of the ground shall have a minimum free open area equal to the cross sectional area of the vent pipe and shall not employ screens. Vent pipes terminating six (6) feet or more above the natural grade of the surface of the ground may have its opening protected by a vent filter of a type approved by the Marshal and further prcvided that such vent filter be equipped with an approved weather hood.
