General Instructions
Who Must Complete Form 2E?
You must complete Form 2E if you answered “Yes” to Item 1.2.4 on
Form 1—that is, if you are a new or existing facility (including
manufacturing, commercial, mining, and silvicultural facilities) that
discharges only nonprocess wastewater.
Where to File Your Completed Form
Submit your completed application package (Forms 1 and 2E) to
your National Pollutant Discharge Elimination System (NPDES)
permitting authority. Consult Exhibit 1–1 of Form 1’s “General
Instructions” to identify your NPDES permitting authority.
Public Availability of Submitted Information
The U.S. Environmental Protection Agency (EPA) will make
information from NPDES permit application forms available to the
public for inspection and copying upon request. You may not claim
any information on Form 2E (or related attachments) as
confidential.
You may make a claim of confidentiality for any information that
you submit to EPA that goes beyond the information required by
Form 2E. Note that NPDES permitting authorities will deny claims
for treating any effluent data as confidential. If you do not assert a
claim of confidentiality at the time you submit your information to
the NPDES permitting authority, EPA may make the information
available to the public without further notice to you. EPA will handle
claims of confidentiality in accordance with its business
confidentiality regulations at Part 2 of Title 40 of the Code of
Federal Regulations (CFR).
Completion of Forms
Print or type in the specified areas only. If you do not have enough
space on the form to answer a question, you may continue on
additional sheets, as necessary, using a format consistent with the
form.
Do not leave any response areas blank unless the form directs you
to skip them. If the form directs you to respond to an item that does
not apply to your facility or activity, enter “NA” for “not applicable” to
demonstrate that you considered the item and determined a
response was not necessary for your facility.
The NPDES permitting authority will consider your application
complete when it and any supplementary material are received and
completed according to the authority’s satisfaction. The NPDES
permitting authority will judge the completeness of any application
independently of the status of any other permit application or
permit for the same facility or activity.
Definitions
The legal definitions of all key terms used in these instructions and
Form 2E are in the “Glossary” at the end of the “General
Instructions” in Form 1.
Line-by-Line Instructions
If you have multiple outfalls, you must submit a separate Form 2E
for each (Sections 1, 3, and 4 only).

Follow-up Requirements for New Dischargers
Note that no later than 24 months after commencement of
discharge from the proposed facility, you must complete
and submit Section 4 of this form. At that time you must test
and report actual rather than estimated data for the
pollutants or parameters listed, unless waived by the
NPDES permitting authority.
EPA Identification Number, NPDES Permit Number, Facility
Name, and Outfall Number
Provide your EPA Identification Number from the Facility Registry
Service, NPDES permit number, and facility name at the top of

FORM 2E—INSTRUCTIONS (CONTINUED)
General Instructions for Reporting, Sampling, and Analysis
Important note: Read these instructions before completing
Section 4 of Form 2E.

If you have sampling and analysis questions, direct them to your
NPDES permitting authority. The authority may request that you do
additional testing, if appropriate, on a case-by-case basis under
CWA Section 308.

General Items
Complete the applicable tables for each outfall at your facility. Be
sure to note the EPA Identification Number, NPDES permit
number, facility name, and applicable outfall number at the top of
each page of any associated attachments.

New Dischargers
You must provide maximum daily and average daily discharge
estimates for the parameters or pollutants listed in Section 4, unless
specifically indicated on the form. Note that if you have the results
of actual analyses for the listed parameters or pollutants, you are
required to report those results rather than submit estimates.

You may report some or all of the required data by attaching
separate sheets of paper instead of completing Section 4 for each
of your outfalls so long as the sheets contain all of the required
information and are similar in format to Section 4.

Report or estimate all parameter or pollutant levels as concentration
and as total mass, except for flow, pH, and temperature. Indicate
the source of all estimates in the appropriate column in the
Section 4 tables using the engineering study codes below. Note
that you are required to conduct follow-up testing and reporting no
later than two years once your facility commences discharge.
Engineering Report Codes
Actual data from pilot plants.................................. 1
Estimates from other engineering reports ............. 2
Data from other similar plants ............................... 3
Best professional estimates .................................. 4
Others ..........................................specify on the form

Reporting of Effluent Data
Report pollutant levels for all pollutants in Section 4 as
concentration and total mass, with the exception of flow, pH, and
temperature. Total mass is the total weight of pollutants
discharged over a day.
Flow, temperature, pH, and fecal coliform organisms must be
reported as mgd, degrees Celsius (°C), standard units, and most
probable number per 100 milliliters (MPN/100 mL), respectively.
Use the following abbreviations in the columns requiring “units” in
Section 4.
Concentration
ppm = parts per million
mg/L = milligrams per liter
ppb = parts per billion
µg/L = micrograms per liter
MPN = most probable number
per 100 milliliters

Mass
lbs. = pounds
ton = tons (English tons)
mg = milligrams
g = grams
kg = kilograms
T = tonnes (metric tons)

Base your determination of whether a pollutant will be present in
your discharge on your knowledge of the proposed facility’s use of
maintenance chemicals and any analyses of your effluent or of any
similar effluent. You may also provide the estimates based on
available in-house or contractor engineering reports or any other
studies performed on the proposed facility.
Pollutants Solely in Intake Water

Existing Dischargers

If you expect a pollutant to be present solely because of its
presence in your intake water, you must still provide an estimate or
analytical result in Section 4; however, you should indicate in
Section 7 in Item 7.1 that you believe the pollutant or parameter to
be present only due to its presence in your source water. See the
instructions under Item 7.1.

You must provide at least one analysis for each parameter or
pollutant, including the following: BOD, TSS, oil and grease,
ammonia (as N), fecal coliform including E. coli and enterococci (if
believed present or if sanitary waste is or will be discharged), total
residual chlorine (if chlorine is or will be used), COD, and TOC (if
non-contact cooling water is or will be discharged), discharge flow,
pH, and temperature (winter and summer).

Testing Waivers
The NPDES permitting authority may waive the testing and
reporting requirements for flow or any of the pollutants listed in
Section 4 if you submit a written request for such a waiver before
or with your application. Contact your NPDES permitting authority
for more information.

You may report quantitative data that you have collected over the
past 365 days if they are representative of your current
operations. The data reported must include maximum daily
discharge, average daily discharge, and number of analyses. Most
existing facilities routinely monitor the pollutants and parameters
listed in Section 4 as part of their existing NPDES permit
requirements.

Sampling

You must collect and analyze samples in accordance with 40 CFR
136. Grab samples must be used for analyses of pH, temperature,
total residual chlorine, oil and grease, fecal coliform (including E.
coli), enterococci (previously known as fecal streptococcus), and
volatile organic compounds. Twenty-four-hour composite samples
must be used for all other pollutants, using at least four grab
samples unless otherwise specified at 40 CFR 136. For a
composite sample, only one analysis of the composite of aliquots is
required.

The collection of samples for the reported analyses should be
supervised by a person experienced in performing sampling of
industrial wastewater. You may contact your NPDES permitting
authority for detailed guidance on sampling techniques and for
answers to specific questions. See Exhibit 1–1 of Form 1 for
contact information. Any specific requirements in the applicable
analytical methods—for example, sample containers, sample
preservation, holding times, and the collection of duplicate
samples—must be followed.

2E-5

FORM 2E—INSTRUCTIONS (CONTINUED)
General Instructions for Reporting, Sampling, and Analysis Continued
The time when you sample should be representative of your
normal operation, to the extent feasible, with all processes that
contribute wastewater in normal operation, and with your
treatment system operating properly with no system upsets.
Collect samples from the center of the flow channel, where
turbulence is at a maximum, at a site specified in your present
NPDES permit, or at any site adequate for the collection of a
representative sample.
Analysis
Except as specified below, all required quantitative data shall be
collected in accordance with sufficiently sensitive analytical
methods approved under 40 CFR 136 or required under 40 CFR
Chapter I, Subchapter N or O. A method is “sufficiently sensitive”
when:
•

•

The method minimum level (ML) is at or below the level of
the applicable water quality criterion for the measured
pollutant or pollutant parameter.
The method ML is above the water quality criterion, but the
amount of the pollutant or pollutant parameter in the facility’s
discharge is high enough that the method detects and
quantifies the level of the pollutant or pollutant parameter in
the discharge.

•

The method has the lowest ML of the analytical methods
approved under 40 CFR 136 or required under 40 CFR
Chapter I, Subchapter N or O, for the measured pollutant or
pollutant parameter.

Consistent with 40 CFR 136, you may provide matrix- or samplespecific MLs rather than the published levels. Further, where you
can demonstrate that, despite a good faith effort to use a method
that would otherwise meet the definition of “sufficiently sensitive,”
the analytical results are not consistent with the quality assurance
(QA)/quality control (QC) specifications for that method, then the
NPDES permitting authority may determine that the method is not
performing adequately and the NPDES permitting authority should
select a different method from the remaining EPA-approved
methods that is sufficiently sensitive consistent with 40 CFR
122.21(e)(3)(i). Where no other EPA-approved methods exist, you
must select a method consistent with 40 CFR 122.21(e)(3)(ii).
When there is no analytical method that has been approved under
40 CFR 136; required under 40 CFR Chapter I, Subchapter N or
O; or otherwise required by the NPDES permitting authority, you
may use any suitable method but shall provide a description of the
method. When selecting a suitable method, you may consider
other factors such as a method’s precision, accuracy, or
resolution.
