Failure to Notify |
The discharger failed to report the benzene and toluene violations that were received on July 13, 2023. The discharger replaced the granular activated carbon prior to taking the confirmation samples. The confirmation samples resulted in no results above the reporting limit. The discharger states the confirmation samples indicate the initial violation was a sampling error and did not report the exceedance. The Monitoring and Reporting Program requires violations be reported within 24-hours of the discharger becoming aware of the exceedance. |
