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 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 MECDC has been and continues to be responsible for the Rules because they have historically been viewed as a public health code, rather than an environmental regulation.
The Subsurface Wastewater Team, within the MECDC's Division of Environmental Health, Drinking Water Program promulgates and administers the Rules. Our mission is to minimize health and safety hazards associated with improperly installed subsurface waste water disposal systems.
What's New at the Subsurface Wastewater Team
On this page:
When installed inside a building advanced treatment devices are regulated by and subject to the Maine Internal Plumbing Rules. Associated disposal fields are still regulated by the Subsurface Wastewater Disposal Rules. For more information on the Internal Plumbing Rules LPIs are advised to contact the Plumbers Examining Board at (207) 624-8603.
The HHE-239 Form, Certificates of Approval, has been updated. This form is used tby Local Plumbing Inspectors to keep track of installation inspections.
The Subsurface Wastewater Team is reviewing policies which are either outdated or have been superseded by revisions to the Subsurface Wastewater Disposal Rules. More information.
MT. BLUE WORKSHOP
September 3, 2014
Back by popular demand, The Maine Association of Professional Soil Scientists, the Maine Association of Wetland Scientists and the Maine Association of Site Evaluators is once again sponsoring the workshop held last year at Mt. Blue State Park in Weld, Maine. The date for the workshop is Wednesday, September 3, 2014. As those of you who attended the workshop last year know, Mother Nature threw us a curve by providing a heavy rain storm just before the workshop. That resulted in most off drained soil pits being filled with water and caused the seasonal streams to fill up. A wet summer also resulted in Webb Lake being at spring levels, vernal pools being filled up and marginal wetlands looking like they would be in the spring. Another result was that a few of the regulators who visited the site in August, under dry conditions, changed some of their initial calls after seeing the sites again on the day of the workshop.
For more information, contact David Rocque, State Soil Scientist at (207) 287-2666 or at David.Rocque@maine.gov.
The Subsurface Wastewater Team has scanned all the hardcopy product files in our possession and uploaded them as Adobe PDF files to this website. The PDF files are linked from the new Products page. No confidential information was copied to our knowledge.
A new checklist is available to assist Local Plumbing Inspectors during system installation inspections.
The PowerPoint presentations and video for the 2013 Basic and the Beyond the Basics workshops are available for viewing and downloading on our training page.
