A board of health may adopt a local on-site sewage disposal systems regulation, only to the extent that it imposes standards or other requirements that are more stringent than or otherwise exceed those set forth in Title 5 of the State Environmental Code, 310 CMR 15.000, and only if, prior to adoption by the board of health, the Department of Environmental Protection shall review and approve any such proposed on-site sewage disposal systems regulation based upon findings that the proposed regulation has a generally recognized scientific basis, is a recommended best practice technique, is necessary to protect unusual local resources that warrant special or enhanced protection, and does not conflict with Title 5 of the State Environmental Code, 310 CMR 15.000.  An appeal of a decision made under a local wetlands ordinance or by-law shall be made to the Department of Environmental Protection in accordance with the Wetlands Protection Act (G.L.
