XII.	PROPOSED FINAL LIMITATIONS 

	The following pronouncement was approved by the EPA on January 18, 2017: 

“As part of the recent triennial review of MS’s Water Quality Standards, revisions were made regarding the bacterial indicator for MS’s freshwaters.

The following information summarizes the revisions made regarding bacteria as part of the recently approved revisions to the WQS regulations:

1)	E. coli will now be the bacterial indicator used for all freshwaters in MS designated as   
      Recreation, Fish and Wildlife Support, and/or Public Water Supply (replacing the use of   
      fecal coliform).

		2) 	The specific language from the WQS regulations states that:

‘Culturable E. coli should not exceed a geometric mean of 126 per 100 ml over a 30-day period, nor should the samples examined during a 30-day period exceed 410 per 100 ml more than 10% of the time.’”

Accordingly, fecal coliform has been removed from the proposed permit and replaced with E. coli.

Flow shall be monitored by instantaneous sampling.  All other parameters shall be monitored by grab sampling.  Flow, chlorine, and pH shall be monitored twice per month.  E. coli, BOD5, and TSS shall be monitored semi-annually.  All parameters shall be reported on an annual Discharge Monitoring Report (DMR). 

The facility has reported “NODI=F” on each annual DMR since year 2016.  NODI=F is an EPA indicator code that means “insufficient flow for sampling.”  In an e-mail from Mr. Cutter Patterson of MDEQ’s ECED to a facility representative on February 11, 2019, he wrote that entering this code on the DMRs is acceptable.
