310 CMR 15.288
Certification of Alternative Systems for General Use
(1) Certification for general use is intended to facilitate the use, under appropriate conditions,
of alternative systems that have been demonstrated to provide levels of environmental protection
at least equivalent to those of conventional on-site systems.
(2) The Department shall certify an alternative system for general use when the Department
determines that the applicant has demonstrated that the alternative system in general usage will
provide a level of environmental protection at least equivalent to that of a conventional on site
system designed and constructed in accordance with 310 CMR 15.100 through 15.255. Such
demonstrations shall include the evaluation of broad scale field use in Massachusetts pursuant
to 310 CMR 15.286, or comparable use in one or more states where relevant physical and
climatological conditions are similar to those in Massachusetts. The required demonstration of
comparable use in one or more states shall include, at a minimum, system use and system
monitoring, and operation and maintenance information at least as comprehensive as the in-state
protocols outlined in 310 CMR 15.280 through 310 CMR 15.288. When relying on system
performance in other states, all available information including but not limited to a copy of the
other state's written approval, testing and performance data shall be provided. The applicant
shall be considered to have demonstrated effective performance of the out of state systems when
the applicant has demonstrated to the Department's satisfaction that at least 90% of the systems
have performed at a level at least equivalent to that of a conventional on-site system.
(3) The Department may establish any special conditions necessary, to ensure adequate
protection of public health, safety, welfare and the environment in its certification of an
alternative system for general use. Such conditions may include without limitation:
specification of site or effluent characteristics; flow limitations; monitoring, testing, and
reporting requirements; operation and maintenance contracting requirements; a requirement that
a certified operator shall operate the system; or financial assurance mechanisms. The
Department may also specify changes or modifications of requirements otherwise applicable to
conventional systems that are appropriate for use of the alternative system.
(4) A Local Approving Authority may impose additional conditions on the use of alternative
systems certified for general use under 310 CMR 15.000 only in accordance with regulations
adopted pursuant to 310 CMR 15.003(3).
(5) Systems with performance superior to conventional systems:
(a) If the Department determines that an alternative system is more effective than
conventional systems in removing nitrates, the Department shall establish the nutrient
removal credit which will be allowed for use of such system pursuant to 310 CMR 15.217,
based on the nutrient removal performance of the approved technology.
(b) In certifying an alternative system for general use, the Department may determine that
any person wishing to use such system need not connect the facility to a sanitary sewer if
such connection is or becomes feasible, if the performance of the alternative system will
provide a level of protection to public health and safety and the environment that is at least
equivalent to that of a sewer system.
(6) Prior to making a determination on an application for general use approval of a technology
pursuant to 310 CMR 15.288, the Department shall publish notice of the application in the
MEPA Environmental Monitor.
(7) Should the Department deny certification of the alternative system for general use, any
person wishing to use such system may file a permit application for use of such alternative
system pursuant to 314 CMR 5.00: Ground Water Discharge Permit Program. Denial under
310 CMR 15.288 shall not prejudice any action on an application pursuant to 314 CMR
5.00: Ground Water Discharge Permit Program.
