1. (1) The Approving Authority shall not approve the construction, upgrade, or expansion of an on-site subsurface sewage disposal system unless it is:

   1. (a) a system serving or designed to receive only sanitary sewage from a facility where the total design flow generated on the facility, is less than 10,000 gallons per day;
   2. (b) a system upgrade approvable in accordance with 310 CMR 15.403 or 310 CMR 15.404; or
   3. (c) a facility for which subdivision approval has been obtained, to construct dwellings with a cumulative total design flow of 10,000 gpd or greater provided that a disposal system construction permit to construct a system in compliance with 310 CMR 15.000 on each of the subdivision lots to be served by a system is obtained and such separate subdivision lots are to be conveyed to independent owners.
2. (2) No system shall serve more than one facility except as explicitly allowed pursuant to 310 CMR 15.010 (division and aggregation) or 310 CMR 15.290 through 15.292 (shared systems).

3. (3) No new system shall be constructed, and no system shall be upgraded or expanded, if it is feasible to connect the facility, or any portion of the facility for which system approval is sought, to a sanitary sewer, except in the following circumstances and particularly to promote recharge of stressed basins, improve low stream flow, or address other local water resource needs:

   1. (a) the system is an alternative system approved for use pursuant to 310 CMR 15.280 through 15.288 and the Department has made the determination that any person using such alternative system need not connect the facility to such sanitary sewer;

   2. (b) the system fully complies with 310 CMR 15.000 and does not require:

      1. 1. a local upgrade approval, unless issued pursuant to 310 CMR 15.405(1)(a) or (b); or
      2. 2. a variance; or
   3. (c) the owner of an existing system has obtained a variance from this requirement pursuant to 310 CMR 15.410 through 15.415.
4. (4) The provisions of 310 CMR 15.000 apply only to the on site collection, treatment and disposal of sanitary sewage, and to the transport and disposal of associated septage and grease, and do not apply to the wastewater containing wastes from any other activity including, but not limited to, activities under the Standard Industrial Classification (SIC) Codes set forth at 310 CMR 15.004(5). SIC Codes are established by the U.S. Office of Management and Budget and may be determined by referring to the publication Standard Industrial Classification Manual. Systems designed to dispose of only sanitary sewage from facilities subject to the following SIC codes may be approved under 310 CMR 15.000. Facilities discharging wastewater that contains wastes from activities under the SIC codes listed below may request a determination from the Department that the wastewater's constituents are substantially similar to sanitary sewage and may be discharged to an on-site septic system.
