Enacted May 5, 2010
248 CMR 10.09(1)(a) requires interceptors and separators "to prevent the discharge of oil, gasoline, grease, sand, and other substances, that are harmful or hazardous to the building drainage system, the public sewer, or sewage treatment plant or other sewage treatment processes." It is the interpretation of the Board that such prevention is required for any building subject to the state plumbing code which utilizes garage or overhead doors sufficiently wide to allow the entrance of a truck or automobile. This interpretation does not apply to single family residential garages or exterior storage sheds that do not contain any plumbing and are not part of any other structure.
Amended November 30, 2011
Installation of outside permanent bollards spaced properly in front of overhead doors so as to prevent the entrance of a truck or automobile shall eliminate the requirements for installation of an interceptor or separator.
