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.
If no biomonitoring data is required,do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
complete.

Contentnea Metropolitan Sewerage District
2019 NPDES Permit Renewal Application
Sludge Management Plan

Sludge Management Plan
CMSD Wastewater Treatment Plant
NPDES Permit No. NC 0032077
Non-Discharge Permit No. WQ0001048
Sludge Production
Contentnea Metropolitan Sewerage District (CMSD) operates a 3.5 MGD 5-stage
biological nutrient removal (BNR) plant which discharges its effluent into Contentnea
Creek in the Neuse River Basin under NPDES Permit No. NC0032077. The plant was
expanded in 2013-14 and most of the aeration basins and clarifiers from the main
treatment process were converted for sludge treatment. The plant currently uses both the
previous sludge processing tanks and new, converted process tanks for sludge treatment.
Waste sludge from the plant is discharged into one of the following for sludge processing
and storage:
One (1) 375,000 gallon sludge digestion tank
Two(2) 347,500 gallon sludge digestion tanks
Two (2) 191,100 gallon converted first stage clarifiers
Two (2) 375,000 gallon converted second stage aeration basins
Two (2) 226,700 gallon converted second stage clarifiers
A combination of diffused air and floating aerators and mixer are utilized for sludge
treatment in these tanks. 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
total sludge stabilization and holding capacity available at the facility is 2,655,600
gallons.
The facility has dewatering capabilities that include dual rotary lobe sludge feed pumps,
dual sludge dewatering screw presses, dual polymer feed systems, dewatered sludge
conveyers, and all associated appurtenances. Additionally, stabilized sludge can de
dewatered in seven (7) sludge drying beds, each bed with a drying surface area of 2,000
square feet.
Sludge Stabilization
Class B pathogen reduction requirements are met using either Alternative 1 [Monitoring
of Fecal Coliform, 503.32(b)(2)] or Alternative 2 [Use of Process to Significantly Reduce
Pathogens, 503.32(b)(3)]. PSRPs utilized for Alternative 2 include Aerobic Digestion and
Lime Stabilization.
Class B vector attraction reduction requirements are met using one of the following
options: Option 3 [Aerobic Digestion, 503.33(b)(3)], Option 4 [SOUR, 503.33(b)(4)],
Option 6 [Alkaline Stabilization, 503.33(b)(6)], Option 9 [Injection, 503.33(b)(9), or
Option 10 [Incorporation, 503.33(b)(10)].

Sludge Disposal
The aerobically stabilized liquefied sludge is land applied at agronomic rates under Non-
Discharge Permit No. WQ0001048. CMSD owns and operates four (4) land application
sites (Sites B-D) totaling 60.37 application acres adjacent to the WWTP. Additionally,
CMSD occasionally contracts with McGill Environmental Services and/or Granville
Farms for sludge disposal.
A 500 gpm sludge loading pump aides CMSD in loading haulers in the event contract
sludge disposal services are required. In the event that this pump is out of service and
CMSD is actively disposing of sludge through either McGill Environmental or Granville
Farms, CMSD will require that a portable pump be provided by the contractor to pump
sludge from either digester basin to the hauler on a temporary basis as is currently done.
Once the sludge loading pump is available for service, it will be placed back into service
and the temporary portable pump(s)removed from service.
As described above, CMSD will also have the ability to dewater sludge prior to disposal
utilizing screw presses. Dewatered sludge shall be disposed of through either McGill
Environmental or Granville Farms.
