4.
De minimis
source. A waste or wastewater source, or a facility
				for treatment or disposal of process wastes, that is determined by the
				department to pose a negligible potential impact on waters of the state even in
				the event of the malfunction of wastewater treatment controls;
5. Land application facility. A facility
				where process wastes are land applied or stored for subsequent land
				application, including land treatment basins;
6. Land treatment basin. An earthen
				impoundment that provides land treatment of wastewater by allowing wastewater
				percolation through the soil at controlled rates which exceed the allowable
				percolation rates under the pond sealing requirements in
				10 CSR
				20-8.020 and
				10 CSR
				20-8.200;
7. No-discharge facility. A facility
				designed, constructed and operated to meet each of the following conditions:
A. To hold or irrigate, or otherwise dispose
				without discharge to surface or subsurface waters of the state, all process
				wastes and associated storm water flows except for discharges that are caused
				by catastrophic and chronic storm events;
B. Process wastes are not land applied during
				frozen, snow covered or saturated soil conditions; and
C. Basins are sealed in accordance with 10
				CSR 20-8 and there are no subsurface releases in violation of
				10 CSR
				20-7.015 or section
				577.155,
				RSMo;
8. One-in-ten
				(1-in-10)-year precipitation. The wettest precipitation expected once every ten
				(10) years for a three hundred sixty-five (365)-day period, based on at least
				thirty (30) years of records from the National Climatic Data Center;
9. Operating location. All contiguous lands
				owned, operated or controlled by one (1) person or by two (2) or more persons
				jointly or as tenants in common or noncontiguous lands if they use a common
				area for the disposal of wastes. State and county roads are not considered
				property boundaries for the purposes of this rule;
10. Process wastes. The waste, waste-water,
				sludges, biosolids and residuals originating from sanitary conveniences, or
				generated during manufacturing or processing, or results from the production or
				use of any raw material, intermediate product, finished product, by-product, or
				waste product and includes discharges from land application fields that occur
				as a result of the land application process;
11. Septage. Septage is domestic wastewater
				sewage sludge that is removed from septic tanks or similar treatment works,
				including domestic wastewater treatment works serving up to one hundred fifty
				(150) persons;
12. Site-specific
				permit. An operating permit that is developed with limitations based on a
				case-by-case review of site-specific conditions;
13. Sludge. The solid, semisolid or liquid
				residue removed during the treatment of wastewater. Sludge includes septage
				removed from septic tanks; and
14.
				Twenty-five (25)-year, twenty-four (24)-hour rainfall. The wettest
				precipitation event for a twenty-four (24)-hour period with a probable
				recurrence interval of once in twenty-five (25) years based on at least thirty
				(30) years of records from the National Climatic Data Center.
