OMARK CARIBBEAN, INC. IS A SAW CHAIN MANUFACTURING COM- PANY WHICH HAS CONSISTENTLY VIOLATED ITS PERMIT CONDITIONS SINCE OCT.,1980, PRIMARILY DUE TO A DELAY OF OVER SIX YEARS IN INSTALLATION OF A BPT TREATMENT SYSTEM AS REQUIRED BY AN EPA ENFORCEMENT COMPLIANCE SCHEDULE LETTER OF JANUARY, 1978. THE CO. DISCHARGES INTO A SMALL UNNAMED TRIBUTARY OF THE BAYAMON RIVER, DESIGNATED SD AS A SOURCE OF DRINKING WATER BY THE WATER QUALITY STANDARDS OF PR. DUE, IN PART, TO FAILURE TO SUBMIT A TIMELY RENEWAL AP- PLICATION PRIOR TO THE EXPIRATION DATE OF ITS FIRST ROUND PERMIT, EPA ISSUED AN ORDER TO SHOW CAUSE TO OMARK ON SEPT. 30, 1981, FINDING THAT OMARK HAD VIOLATED ITS EFFLUENT LIMITATIONS ON NUMEROUS OCCASIONS, HAD FAILED TO CONSTRUCT NECESSARY TREATMENT FACILITIES, AND WAS DISCHARGING POLLU- TANTS WITHOUT AN EFFECTIVE NPDES PERMIT. A COMPLETE, RE- VISED RENEWAL APPLICATION WAS NOT SUBMITTED TO EPA UNTIL MAY 31, 1983; THUS OMARK CONTINUED TO DISCHARGE POLLUTANTS WITHOUT AN EFFECTIVE NPDES PERMIT UNTIL DEC. 1, 1983, THE EFFECTIVE DATE OF ITS SECOND ROUND PERMIT. EPA AND EQB COM- PLIANCE INSPECTIONS DURING 1982, 1983, AND 1984 DISCLOSED NUMEROUS MONITORING, REPORTING AND MANAGEMENT RESPONSIBILITY VIOLATIONS; AND OMARK'S DMR'S DEMONSTRATE A CONSISTENT PAT- TERN OF SIGNIFICANT EFFLUENT LIMITATION VIOLATIONS DATING FROM JAN., 1981.
