I can't answer the "why"...
There are changes proposed to the impervious criteria. The upper limit would still be 30 % but the requirements associated with it are different. These changes are laid out in SB 352. Nothing on any of these issues is final though until someone puts paper in front of the Governor and it get's signed.
New Septic rules were adopted in February. The State still bases the size of the septic on the number of bedrooms. The biggest difference we are seeing is with developed, undersized lots. If you have an existing camp or house on a lot that is too small to meet the loading standards then you will not be allowed to expand the house or camp in any way. Maintaining existing conditions is allowed, expansion is not, even if it is not technically adding bedrooms. If you have a lot large enough to meet loading standards or are on municipal sewer then this is not an issue.
