The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). Effluent samples for self -monitoring purposes must be obtained during representative effluent discharge below all waste treatment. The tests will be performed during the months of January, April, July and October. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGE6C.

We are requesting a major modification to the existing NPDES permit for these changes. The following items are included with this letter: 1. NPDES Permit Application — Short Form C — WTP 2. Check for $215.00. The proposed changes to the water treatment plant include two additions to the treatment plant building for an iron removal system and a relocated ammonia injection system. Other changes to the treatment plant to support these two new processes include a new backwash lagoon to separate the color and softener backwashes, drying beds for the iron vessel backwash, new high service and process pumps, a 25,500 gallon ground storage tank and associated valving, piping and controls. One new color vessel and one new softener vessel will also be added during this process and will increase the treatment plant capacity to 2.0 MGD. The existing 4-inch line from the softener and color vessel backwash will be connected to the proposed 6-inch backwash discharge from the iron removal process. The existing 4-inch line will be left in place as a bypass with the majority of the backwash going through the new 6-inch discharge line which will be installed parallel to the 4-inch. The 6- inch will discharge at the same point as the 4-inch, East Prong Sanders Creek.

Backwash water from the iron removal vessels will be discharged into the sand drying beds and allowed to percolate to an under drain system. After several hours of settling, water from the top will be decanted and discharged in accordance with the NPDES permit. 2. Precipitated iron which deposits on the sand layer in the sand drying beds will be manually removed from each bed when its depth becomes a minimum of 8- inches with a small front-end loader and shovels. 3. Dried sludge will be taken from the beds and deposited in a concrete containment area on site until a sufficient quantity is accumulated to fill a dump truck. 4. Sludge will be deposited into a dump truck and transported to the local landfill where it will be disposed. °s it`} rlCfyT �� t I 4,y 1 Y �� a _ ?rsi P� s��'�i"f'�.. •�"' !R`, ' -. ��Y �A`�r pia. .- � a.- ,pp WIN Fl qg% it s qA -y BM FIANOF TO CREEK DISCHARGE WEST CARTERET WATER CORPORATION FLOW SCHEMATIC MAY 15, 2006
