Standard of Practice	Explanation
10. Open Discharge System	See Pg. 207, Fig. Typical OD 1 in Appendix "B" See Pg. 208, Fig Typical OD 2 in Appendix "B" See Pg. 209, Fig. Typical OD 3 in Appendix "B"
10.1. Design Standards
10.1.1. A system designed to discharge effluent to the surface of the ground shall contain the effluent on the property.	See Pg. 160, Open Discharge in Appendix "B"
10.1.2. An open discharge system shall be designed to minimize effluent pooling on the ground surface during nonfreezing temperatures.
10.1.3. At the point of discharge of effluent to the surface, the soil the effluent is discharged onto shall be protected from erosion. Intent: The design of the point of discharge must include landscaping to disperse the effluent allowing the quick evaporation and absorption of the effluent, and must protect the soil from erosion.	See Pg. 210, Fig. OD 1 in Appendix "B" See Pg. 211, Fig. OD 2 in Appendix "B" See Pg. 211, Fig. OD 3 in Appendix "B"
10.2. Installation Standards
10.2.1. An effluent discharge to the ground surface shall not be located within 45 m (150 ft.) of a water source, 45 m (150 ft.) of a water course, 45 m (150 ft.) of a dwelling, and 90 m (300 ft.) of a property line.	See Pg. 38, Article 7.1.6. for Vertical Separation Requirements. See Pg. 178, Fig Vertical Separation in Appendix "B"
10.2.2. The soil receiving the effluent from an open discharge system shall have a percolation rate slower than 5 minutes per inch. Intent: The soil the effluent is discharged onto must have a percolation rate slower than 5 minutes per inch as required in Article 7.1.5. The soil percolation rate may exceed 60 minutes per inch. Vertical separation distances of Article 7.1.6. must also be met.	See Pg. 38, Article 7.1.5
10.3 Requirements for Materials
10.3.1. Piping used in an open discharge system shall be certified for that use or comply with Appendix A Piping Materials list for a pressure effluent line.	See Pg. 27, Article 3.3.1 See Pg. 93, Table A.5.A in Appendix "A"
