Maine is a predominantly rural state, and relies heavily on decentralized sewage disposal facilities for disposal of human waste, i.e., septic systems. The State of Maine has regulated septic systems as a public health issue since 1920 to varying degrees. Over the years, the Maine State Plumbing Code, Subsurface Wastewater Disposal Rules (Rules) in their various versions have been administered by the Maine Center for Disease Control and Prevention (MECDC) and its predecessors.

The Subsurface Wastewater Team, within the MECDC's Division of Environmental Health, Drinking Water Program is charged under 42 MRS § 42 (3, 3-A, 3-B) to adopt rules which regulate subsurface sewage disposal systems, licensing of persons to evaluate soils for subsurface wastewater disposal systems, and inspection of plumbing and subsurface waste water disposal systems.

NOTICE REGARDING THE SUBSURFACE RULES

The Department has identified a significant error in Table 4C of the Subsurface Wastewater Disposal Rules, 10-144 CMR 241.  Specifically, the design flow standard for Marinas currently reads:


Marina

100 gpd plus 10 gpd per slip or mooring (clothes washers are not included; design flow for clothes washers must be calculated separately); w/bathrooms add 30 gpd per slip; w/o bathrooms add 100 gpd per slip.

This design flow standard for marinas should read:


Marina

100 gpd plus 10 gpd per slip or mooring plus 12 gpd per employee without bathrooms;

30 gpd per slip or mooring plus 12 gpd per employee with bathrooms (clothes washers are not included; design flow for clothes washers must be calculated separately)

Site Evaluators should use the correct design flow standard when designing a subsurface wastewater disposal system to serve a marina.  The normal state variance process can be utilized should an LPI require it as verification of the design flow standard discrepancy.  Please contact the Department should you have any questions.

Policy for Variances

The Subsurface Wastewater Team has adopted a policy on the use of microfiltration advanced treatment systems to overcome technical difficulties on sites with marginal or failing conditions. The policy may be downloaded. Please forward questions to David Braley, Team Leader, Subsurface Wastewater Team.

Presby Environmental Inc. Reminder

This substitution prohibition does not apply to designs which generically specify a fabric wrapped tube. The Division apologizes for any confusion or inconvenience resulting from inclusion of Presby Environmental Inc. products in Table 6H.
