THE CITY OF HORSE CAVE (CITY), WITH A POPULATION OF ABOUT 2000, OWNS AND OPERATES A 0.4 MGD TRICKLING FILTER SYSTEM (PLANT) AND WAS ISSUED NPDES PERMIT NO. KY0041092 TO DISCHARGE INTO A SUBTERRANEAN STREAM WHICH RUNS INTO THE GREEN RIVER. SINCE THE ISSUANCE OF THE NPDES PERMIT IN JUNE 1983, THE CITY HAS NOT BEEN ABLE TO CONSISTENTLY MEET ITS PERMIT EFFLUENT LIMITATIONS. IN CONJUNCTION WITH THE CITY OF CAVE CITY, PARK CITY AND THE MAMMOTH CAVE NATIONAL PARK, HORSE CITY FORMED THE CAVE- LAND SANITATION AUTHORITY (CSA) TO FINANCE, CONSTRUCT AND MAINTAIN A REGIONAL WASTEWATER TREATMENT SYSTEM WHICH WOULD UPGRADE EXISTING LEVELS AND TO TRANSPORT THE EFFLUENT AWAY FROM THE SUBTERRANEAN STREAMS AND DIRECTLY INTO THE GREEN RIVER. CSA HAS PROCURED FINANCING FROM THE ENVIRONMENTAL PROTECTION AGENCY (EPA), FARMERS HOME ADMINISTRATION, THE NATIONAL PARK SERVICE, AND THE KENTUCKY COMMUNITY DEVELOP- MENT BLOCK GRANT PROGRAM. THE ATTACHED CITY RESOLUTIONS PROVIDE CSA WITH LEGAL AUTHORITY.
