Downstream Location: mouth of Mauls Swamp
Parameters: Temperature, dissolved oxygen, fecal coliform, Total nitrogen
Special instream monitoring locations or monitoring frequencies:
MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demonstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes No
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) (Y or N)
(If yes, then attach schematic, toxics spreadsheet, copy of model, or, if not modeled, then old
assumptions that were made, and description of how it fits into basinwide plan)
Additional Information attached? (Y or N) If yes, explain with attachments.

Brief of WLA Analysis
Facility has had alot of action in the past few years, due to in part to expansion, SOC, (due to flow violations), and Basin
Plan coordination making for a short-term permit. I talked with Kevin Miller [WaRO] and Joe Pierce [Pretreatment] on
12/7/93 and both informed me that no changes have occurred since the last WLA to hold up any processing.
Pretreatment has backed off any type of full blown program; the Town's major industry only discharges domestic waste,
cooling water and non -detergent rinse water. The Town is fully compliant, (Pretreatment Effluent data, contained in
attached report confirms this for toxics), and has been consistently for the past few years. The SOC is for an expansion
and relocation, which they already have an A to C for. Since no other negative information or Basin Plan impacts are
involved in this Permit, I will recommend reissuance with the same limits.
Due to swampiness of area and organic nature of nitrogen released in effluent, language acknowledging more stringy
nutrient controls in the future should be used. I will recommend Total Nitrogen be one of the parameters monitored
instream.

lnstream monitoring portraying very low summer DO % saturations, with possible super -saturated winter
time waters. The effluent has a substantial portion of organic nitrogen which could exacerbate this
situation. l will recommend instream monitoring of nitrogen due to this likely situation. 1.6171 /011aC leMIMA
This area is water quality impacted, but the sources and causes of the problems are not fully understood. The managem
strategy is pending further investigation and will be targeted for the 1998 Neuse Basin Plan update. In the interim, wasteloi
will be evaluated on a case -by -case basis.

_x_ Parameter(s) are water quality limited. For some parameters, the available load capacity of
the immediate receiving water will be consumed. This may affect future water quality based
effluent limitations for additional dischargers within this portion of the watershed.

INSTREAM MONITORING REQUIREMENTS
Upstream Location: NCSR 1440
Downstream Location: Downstream 2 miles
Parameters: Temperature, dissolved oxygen, fecal coliform, Toen
Special instream monitoring locations or monitoring frequencies:
Upstream and downstream samples shall be grab samples. Stream samples shall be collected three time
week during June, July, August, and September and once per week during the remaining months of the
MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demonstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes No
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) (Y or N)
(If yes, then attach schematic, toxics spreadsheet, copy of model, or, if not modeled, then old
assumptions that were made, and description of how it fits into basinwide plan)
Additional Information attached? (Y or N) If yes, explain with attachments.
