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.

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:
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:
100 gpd plus 10 gpd per slip or mooring plus 12 gpd per employee without bathrooms;
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.
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.
Contrary to Table 6H of the Subsurface Wastewater Disposal Rules (Permitted Substitution of Proprietary Devices) no effluent disposal product(s) may be substituted for any Presby Environmental, Inc. product(s). Pursuant to the January 11, 2010 registration approval letter for the Advanced Enviro-Septic no other company or manufacturer’s product(s) may be substituted for the Advanced Enviro-Septic or Enviro-Septic, at the request of Presby Environmental, Inc. although the Advanced Enviro-Septic may be substituted for Enviro-Septic.
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.
The Division now accepts completion of International Association of Certified Home Inspectors' online How to Inspect Septic Systems course for intial inspection certification and for continuing education for presently certified System Inspectors. This course is the largest, most in-depth septic system course of its kind according to InterNACHI.
This septic system inspection course is open and free to all InterNACHI members. If one is not a member only a portion of the course can be viewed.
The How to Inspect Septic Systems course includes 10 credit hours; 79 minutes of video; 61 quiz questions in 9 quizzes; a 50-question final exam; and a printable Certificate of Completion.
Upon reciept of a copy of the Certificate of Completion the Division will issue a Certified Septic System Inspector certificate to an applicant.
