SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points 1) POTWs with a design flow rate greater than or equal to 1 0 mgd, 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403), or 3) POTWs required by the permitting authority to submit data for these parameters
• At a minimum, these results must include quarterly testing for a 12 -month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution Do not include
information on combined sewer overflows in this section All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted
• If you have already submitted any of the information requested in Part E, you need not submit it again Rather, provide the information
requested in question E 4 for previously submitted information If EPA methods were not used, report the reasons for using alternate methods
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E

Sludge Management Plan

Sludge Management Plan
Benson Wastewater Treatment Plant
NPDES Permit No. NC0020389
Non -Discharge Permit No. WQ0012514
The Town of Benson operates a 1.9 mgd modified biological nutrient removal (BNR) plant
which discharges its effluent into Hannah Creek in the Neuse River Basin under NPDES Permit
No. NC0020389. Waste sludge from the modified BNR plant is discharged to the existing
3,247,000 gallon capacity aerated basin for long-term sludge stabilization and storage.
Periodically, the sludge is allowed to settle in the basin and the supernatant is withdrawn and
recycled back to the plant headworks for reprocessing. The stabilized sludge which meets
pollutant limits and Class B pathogen reduction and vector attraction reduction requirements is
later disposed of in accordance with Non -Discharge Permit No. WQ0012514.
The Class B pathogen reduction requirements are met using either Alternative 1 [Monitoring
of Fecal Coliform, 503.32(b)(2)] or Alternative 2 [Use of PSRP, 503.32(b)(3)]. The vector
attraction reduction requirements are met using Option 3 [503.33(b)(3)], Option 6 [503.33(b)(6)],
Option 9 [503.33(b)(9)], or Option 10 [503.33(b)(10)].

Fisher's Exact Test
A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.
Test Passes!

Wilcoxon Rank Sum Test
Rank
Sum - Effluent Group(treatment): 147 Control'Group: 153
Mann-Whitney U = 69.0 n1(treatment) = 12 n2(control) = 12
The critical
value from
TABLE A.15 (0.01 Level of T) for the above n values:
Critical T = 109
147 > 109
The Sum of
the Ranks of the effluent group is greater than the significant I
value from
the table.
Therefore there is no significant difference between
the means of the effluent and control groups and the test passes.

Fisher's Exact Test
A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.
Test Passes!

Fisher's Exact Test
A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.

a/A = 1.00 b/B = 0.92
Success is: survival
Critical b value = 8

The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.
