e Determining Nonconforming Systems - e One of the major changes in the Shoreland Management Regulations is the requirement of proof that propeny has a conforming onsite treatment system. This burden of proof is on the propeny owner and is necessary to receive a permit to complete any improvement of the property. Chapter 7080 lays out requirements for a confomling system on page 9nOXO.OO60 (Treatment required). This description has been transferred into the flow chart in Figure H-6. The discussion is a step- by-step walk-through of this flow chan, explaining the decision process. Following the flowchart results in determining whether a propeny has a conforming or nonconforming onsite system. Lack of a System The first detennination is whether a system is located on the property at all. All properties with running water must have an onsite treatment system. If no system is found, that property is automatically consid- ered nonconforming. If no toilet waste is included in the effluent. a gray water system (7080.210 Appendix A, Subpart IV, Section 3 Gray Water Systems, Page 32) may be used in place of a complete onsite system. If the propeny is going to be further developed. a complete system should be installed. Cesspool, Dry Well or Seepage Pit The definition of these systems is included in Chapter 7080J)()20. (See Figures H-7 and H-8.) It includes :my underground pit into which HOUSE HOUSE SEWER /GROUND SURF^CE - >:w."L%:.~'-~/.~~'~~~~"<'~9.'~~"~ T PIPE .' I OR BAFFLES UTLET SEWER 4-- 6- DIA.
