I.	FACILITY INFORMATION

Facility Name:  	TransAmerican Waste Central Landfill Inc, Central Landfill Facility
Facility Address:  	8680 Highway 11 North 
	McNeill, MS  39457    
McNeill, 
Permit No.:  		MSS054445
SIC Code:  		4953
Permit Writer:  	Carter Cress
EPD Branch:  		Water II  

II.	NATURE OF BUSINESS

This facility is a municipal solid waste landfill.  

III.	EFFLUENT AND RECEIVING STREAM FLOW DATA

Outfall No.	Discharge Type	Total Area Drained	Receiving Stream	Current Status	
001	Storm water	33.1 acres	

Unnamed Tributary of East Hobolochitto Creek
	Constructed	
002	Storm water	28.9 acres		Not Constructed	
003	Storm water	28.1 acres		Constructed	
004	Storm water	24.7 acres		Constructed	
005	Storm water	11.3 acres		Not Constructed	
006A	Storm water	13.5 acres		Constructed	
006B	Storm water	24.4 acres		Not Constructed	

Discharges from outfalls 001, 003, 004, and 006A consist of storm water runoff associated with the construction, development, and operation of the municipal landfill, except for working face runoff and leachate.  The storm water runoff is collected from each outfall and treated in each outfall’s own unique sedimentation pond.  

Once constructed, outfalls 002, 005, and 006B will operate in an analogous manner.  Each outfall will also have its own sedimentation pond constructed to collect and treat storm water runoff.     

The outfalls discharge into an unnamed tributary of East Hobolochitto Creek which is located in the Pearl River Basin.  The receiving stream is designated as Fish and Wildlife.    
IV.	TOTAL MAXIMUM DAILY LOAD (TMDL) AND 303(d) ISSUES

None; the receiving stream is not listed on the Mississippi 2018 Section 303(d) List of Impaired Water Bodies.  

V.	TYPE OF WASTEWATER TREATMENT

A constructed sedimentation pond is associated with outfalls 001, 003, 004, and 006A.  Additional sedimentation ponds will be constructed for outfalls 002, 005, and 006B.  

The sedimentation ponds will treat the collected storm water runoff via sedimentation (settling) and evaporation.

***Turbidity outside the limits of a 750-foot mixing zone shall not exceed the background 
      turbidity at the time of discharge by more than 50 NTU. 

The parameters will be monitored once semiannually with a grab sample.  Results will be reported annually.  

There have been several conditions added to this reissuance.  These include: 3 limitations that describe what the effluent “shall be free from”, storm event sampling records that must be kept, recording/submittal requirements that must be performed once outfall(s) 002, 005, and/or 006B are undergoing construction and once discharge from the outfall(s) has commenced, SWPPP certification form submittal instructions, and SWPPP development, components, controls, implementation, and amendments.
