SUPPLEMENTAL APPLICATION INFORMATION
F_ _
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.

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.

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
t
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.

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.
