Floor Drains in commercial buildings
COMMERCIAL BUILDINGS UTILIZING OVERHEAD GARAGE DOORS
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 all buildings which utilize garage or overhead doors sufficiently wide to allow the entrance for a truck or automobile.
Interceptors and separators are not required for:
- Singles family residential garages;
- Exterior storage sheds that do not contain any plumbing and are not part of any other structure; or
- The following situations, which because they are not currently in the plumbing code require a variance application per 248 CMR 3.04(2) but will not require attendance at a Board meeting:
- Showrooms used for the purpose of selling used or new trucks or automobiles which are located within a structure classified by the Plumbing Code, 248 CMR 10.10(18)(table 1), as a mall (covered) or retail (mercantile) that is open to and used by the public. However, this exception shall only apply to showrooms located on one floor which hold a maximum of six vehicles;
- Installations where outside permanent bollards are spaced in front of overhead doors so as to prevent the entrance of a truck or automobile; and
- Showrooms used for the purpose of selling used or new trucks or automobiles which are located within a structure classified by the Plumbing Code, 248 CMR 10.10(18)(table 1), as a mall (covered) or retail (mercantile) that is open to and used by the public. However, this exception shall only apply to showrooms located on one floor which hold a maximum of six vehicles;
