			 issue a permit in compliance with rule
			 3701-29-09

(1)
									 Gray water
			 discharged to all GWRS shall only consist of domestic type flows having the
			 consistency and strength typical of gray water from domestic households. The
			 source of gray water may include water from bathing, showering, washing clothes
			 or laundry sinks. Gray water shall not contain water used to wash diapers, or
			 other materials soiled with human excreta or infectious materials, or
			 wastewater that has come in contact with toilet waste, toxic substances,
			 cleaning chemicals other than soap, water softener backwash or any other
			 hazardous household products;
(2)
									 Design flows to
			 GWRS shall be determined based on the flow rate of the fixture(s) or the

			 system;
(3)
									 The isolation distance requirements of paragraph
			 (G)(3) of rule
			 3701-29-06
			 of the Administrative Code;
(4)
									 Shall be used

			 unless a legally recorded easement permits access to and application on another
			 property;
(5)
									 Type 1, 2, or 4 GWRS shall include a readily
			 accessible diversion valve in the sewage line from the dwelling or building so
			 all the gray water can be directed into the STS or the approved public sewer
			 system when necessary. The diversion valve must be visibly
			 labeled;
(6)
									 All pipes conveying gray water must be labeled with
			 the following words in capital letters: "Caution: Non-potable water, do not
			 drink" or the pipe shall be purple or purple striped in color;
(7)
									 If a type 1, 2
			 or 4 GWRS fails or is suspected of failing, the owner shall immediately divert
			 the gray water to the approved public sewer system or STS serving the dwelling
			 or structure;
(8)
									 The gray water system owner shall maintain a record of
			 the GWRS that includes the location of the system, identifies the fixture(s)
			 that are the source of the gray water, describes the system design and
			 maintenance requirements, and includes the calculation of the total minimum
			 irrigation area required;
(9)
									 The system owner shall ensure that the GWRS is
			 properly operated and maintained; and
(10)
									 Except for type
			 3 GWRS, no reduction in the design and sizing of the STS shall be permitted
			 when using a GWRS. All other sewage from a dwelling or structure shall be
			 discharged to an approved STS or sanitary sewer.
