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 EA 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.

NPDES FORM 2A Additional Information

Additional information, if provided, will appear on the following pages.
A. USGS Topographic Map sized 8.5" x 11" in response to Item B.2.
The map shows the area surrounding the WWTP.
1. The Map shows the main structures of the WWTP.
2. There are no injection wells.
3. There are no known wells or springs within 0.25 miles of the WWTP. The adjacent stream, "Calico Creek" is also the
discharge location.
4. Digesters, Sludge Dewatering and Sludge Dryers are also located on the WWTP Site.
5. The WWTP does not receive or process hazardous waste.
B. See Flow Schematic in partial response to Item B.3. A description of the WWTP process is as follows:
1. Mechanical Bar Screen - Removes trash.
2. Influent Pumps - Pumps influent to grit removal structure.
3. Aerated Grit - Removes grit via gravity separation and air lift.
4. Oxidation Ditches - Biological treatment units.
5. Chemical Feed - Adds alum or ferric chloride to effluent of oxidation ditches to remove phosphorous or improve
settling characteristics to enhance BODS and TSS removal.
6. Clarifiers - Removes suspended solids.
7. Traveling Bridge Tertiary Filters - More thoroughly removes solids.
8. Post Aeration - Aerates effluent to maintain minimum dissolved oxygen level.
9. Ultraviolet Disinfection - Intense light in contact with pathogenic organisms causes the organisms to become
inactivated and renders them harmless.
10. Sludge Return and Waste Pumps - Transfers sludge underflow from the clarifiers or sludge from transfer pumps
either back to the oxidation ditches (return) or to the digester (waste).
11. Sludge Digester - Tanks to hold sludge while its organic matter biologically decomposes. Supernatant goes to
influent before bar screen.
12. Belt Press - Dewaters sludge and directs solids to the sludge dryer.
13. Sludge Dryer - Uses heat and/or lime to further dewater and stabilize sludge solids.
14. Sludge Storage - Provides a place to keep stabilized sludge until it can be utilized/disposed.
15. Secondary Sludge Pumping Station - Directs belt press filtrate back to the head reactor basins.
16. Flow Measuring and Recording - Measures and records influent and effluent flow rates and volumes. Send signals
for pacing chlorination/dechlorination rates and samplers.
17. Effluent Sampling - Automatically collects samples paced by measured flow or at specified time intervals.
C. See Site Plans G713 and G813 which provide a more detailed view of plant piping in response to Item B,3.
