Notes/Remedial Actions

No remedial actions were stated. The State Police Hazmat report identifies sulfur dioxide as the released chemical, but does not mention hydrogen sulfide. The LDEQ report identifies hydrogen sulfide as the released chemical, but does not mention sulfur dioxide. No explanation is given for this discrepancy. The report also states that the RQ for H2S is 500 lbs, which is presumably why they state that the 100 lbs released was below the reportable quantity. Notification made that #1 Incinerator was emitting higher than permitted sulfur dioxide emissions. Placid's engineering department determined less than the established RQ was actually released from this event. Placid will ensure any excess emissions are accounted for in other applicable reports. SPOC report states material did go offsite.
