10 144 CMR 241,INTRODUCTION, 1 Scope These Rules govern the general regulation of all subsurface wastewater systems No person may erect a. structure that requires a subsurface waste water disposal system until documentation has been provided to the. municipal officers that the disposal system may be constructed in compliance with these rules 30 A M R S. 2 Duties and powers of Local Plumbing Inspector The Local Plumbing Inspector hereafter LPI shall enforce all the. provisions of these Rules He or she shall act on any question concerning the method or manner of construction and. the materials to be used in the installation of a system except as may be specifically provided for by other. requirements of these Rules, 3 Application for disposal system permits The LPI shall receive applications for disposal system permits issue. permits for the installation of systems inspect the premises for which such disposal system permits have been. issued and enforce compliance with the provisions of these Rules. 4 Notices and orders The LPI shall issue all necessary notices or orders pertaining to removal of illegal or unsafe. conditions the requirement of necessary safeguards during construction and compliance with all requirements of. these Rules for the safety health and general welfare of the public. 5 Inspections The LPI shall make all the inspections required these Rules The LPI may engage such expert opinions. as may be deemed necessary to report upon unusual technical issues that may arise subject to the approval of the. municipal officers, 6 Credentials The LPI shall carry proper credentials of the office while inspecting any and all systems and premises. in the performance of his or her duties, 7 Annual report At least annually the LPI must submit to the municipal officers of the jurisdiction a written. statement of code enforcement activities in form and content as shall be prescribed by such authority. 8 Contact Information Contact information herein is accurate as of the effective date of these Rules The.

1 Non engineered systems A site evaluator licensed in Maine shall design non engineered systems. 2 Engineered systems A site evaluator licensed in Maine shall provide observation hole logs and soil profile. descriptions as described in Section 10 C 4 for engineered systems A professional engineer licensed in Maine. shall design engineered systems and may consult with the site evaluator. C DESIGN REQUIREMENTS, 1 All systems In designing any system the site evaluator and or professional engineer shall consider lot size and. configuration slope surface drainage soil characteristics the presence and depth of limiting horizons within the. soil soil permeability type and organic loading rates of wastes BOD and TSS and the projected design flow. 2 Types of wastes Systems must be designed to receive all wastewater from the structure served except in the. following cases,Section 1 10 144 CMR 241 Page 1, a Black or grey wastewaters only Separate systems may be designed to receive only grey wastewater or only. black wastewater as allowed in Section 4, b Laundry wastes Laundry wastes from a single family dwelling may be discharged into a separate laundry. disposal field See Section 4 P, c Hot tubs Hot tubs must not discharge into any disposal system utilized for any other wastewater but may be. discharged into a grey water disposal system,D DEPARTMENT OF ENVIRONMENTAL PROTECTION.
1 License Not Required In accordance with 38 M R S 413 a waste discharge license is not required for the. installation operation or maintenance of a subsurface wastewater disposal system for the subsurface disposal of. domestic wastewater or other wastewater from commercial industrial or residential sources which is of a similar. quality constituents and strength or of a lesser pollutant load strength to that of domestic wastewater provided it. has been designed and installed in conformance with these Rules This includes but is not limited to wastewater. normally associated with hospitals restaurants nursing homes schools hotels motels and medical dental. veterinary facilities and backwash from water treatment systems provided all pollutants including but not limited. to radionuclides will be appropriately and adequately treated and similar types of wastewater. 2 License Required In accordance with 38 MRS 413 a waste discharge license is required for the installation. operation or maintenance of a subsurface wastewater disposal system for the subsurface disposal of wastewater from. commercial industrial or residential sources which has constituents unlike that of or of significantly higher. strength than that of domestic wastewater and is therefore beyond the jurisdiction of these Rules This includes. but is not limited to wastewater normally associated with abattoirs commercial car washes egg washing facilities. and industrial processes, 3 Wetland jurisdiction The Army Corps of Engineers makes jurisdictional determinations and issues wetland permits. for filling dredging and other construction in certain wetlands under Section 10 of the Rivers and Harbors Act of. 1899 The Army Corps of Engineers provides the same function under Section 404 of the Clean Water Act for all. other wetlands with program oversight by the U S Environmental Protection Agency EPA With the combination. of these two Acts all wetlands regardless of size are regulated by EPA and the Army Corps of Engineers The. Maine Department of Environmental Protection MDEP regulates activities in or adjacent to coastal or freshwater. wetlands as defined in Chapter 2 under the Natural Resources Protection Act NRPA at 38 M R S 480 A et seq. 4 Permit by Rule The installation or repair of a system does not require a NRPA permit from the MDEP provided all. Sections of these Rules are met The requirements contained in these Rules are designed to meet the same. requirements contained in MDEP s Permit by Rule program for soil disturbance adjacent to or within a protected. natural resource associated with a wetland and or other MDEP regulated NRPA natural resources. E PROHIBITIONS, 1 The use of system cleaners that contain restricted chemical materials is deemed a discharge of industrial wastes and. is prohibited, 2 Chemicals other than normal amounts of household cleaners must not be disposed of in the disposal field. Examples of prohibited chemicals include but are not limited to pesticides oil based paints or stains paint. remover paint thinner acids gasoline solvents glues and adhesives pool chemicals paint paint thinner. commercial grease and oil darkroom chemicals and medications. 3 Roof drains and foundation drains Roof drains and foundation drains must not be connected to systems. 4 The use of septic tank cleaners and degreasers prohibited The Department does not recognize any additive as being.
