Public Availability of Submitted Information

General Instructions
Who Must Complete Form 2F?

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 2F (or related attachments) as
confidential.

You must complete Form 2F if you answered “Yes” to Item 1.2.5
on Form 1—that is, you are a new or existing facility and your
discharge is composed entirely of stormwater associated with
industrial activity (excluding discharges from construction
activity under 40 CFR 122.26(b)(14)(x) or (b)(15)) or composed
of stormwater and non-stormwater and are seeking coverage
under an individual National Pollutant Discharge Elimination
System (NPDES) permit. Note that applicants in the latter
category must also complete Forms 2C, 2D, or 2E, as
applicable. See inset below.

You may make a claim of confidentiality for any information that
you submit to EPA that goes beyond the information required by
Form 2F. Note that NPDES permitting authorities will deny
claims for treating any effluent data (estimated or actual) 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 in Part 2 of Title 40 of the Code of Federal
Regulations (CFR).

Notes
•

•

•

•

•

Form 2F must be completed by any operator of a
facility that discharges stormwater associated with
industrial activity or the operator of any
stormwater discharger that EPA is evaluating for
designation as a significant contributor of
pollutants to waters of the United States, or as
contributing to a violation of a water quality
standard.
For discharges composed entirely of stormwater,
the operator must complete Form 2F in
conjunction with Form 1.
For discharges of stormwater combined with
process wastewater, the operator must complete
and submit Form 2F, Form 1, and Form 2C.
Process wastewater is water that comes into
direct contact with or results from the production
or use of any raw material, intermediate product,
finished product, byproduct, waste product, or
wastewater.
For discharges of stormwater combined with
nonprocess wastewater, the operator must
complete Form 2F, Form 1, and Form 2E.
Nonprocess wastewater includes noncontact
cooling water and sanitary wastes that are not
regulated by effluent guidelines, except
discharges by educational, medical, or
commercial chemical laboratories.
For new discharges of stormwater associated with
industrial activity that will be combined with other
new non-stormwater discharges, the operator
must submit Form 2F, Form 1, and Form 2D.

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 show 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.

the application. The site map must include the following
information:
• Each of its drainage and discharge structures.
• The drainage area of each stormwater outfall.
• Paved areas and buildings within the drainage area of each
stormwater outfall; each past or present area used for
outdoor storage or disposal of significant materials; each
existing structural control measure to reduce pollutants in
stormwater runoff; materials loading and access areas; and
areas where pesticides, herbicides, soil conditioners, and
fertilizers are applied.
Each hazardous waste treatment, storage, or disposal
facility (including each area not required to have a
Resource Conservation and Recovery Act permit and is

you will be asked to provide information by outfall number
(Sections 2, 4, 5, and 7).

Section 4. Pollutant Sources
Item 4.1. List all outfalls discharging stormwater. Provide an
estimate of the impervious surface area drained by the outfall.
Specify units of measure. (Impervious surfaces are surfaces
where stormwater runs off at rates significantly higher than
background rates—e.g., predevelopment levels. They include
paved areas, building roofs, parking lots, and roadways.)

Section 2. Improvements
Item 2.1. Indicate if you are required by any federal, state, or
local authority to meet an implementation schedule for
constructing, upgrading, or operating wastewater treatment
equipment or practices or any other environmental programs
that could affect the discharges described in this application.

conditions, administrative enforcement orders, enforcement
compliance schedule letters, stipulations, court orders, and
grant or loan conditions. If yes, continue to Item 2.2. If no, skip
to Section 3.

Provide an estimate of the total surface area (impervious and
pervious areas) drained by each outfall (within a mile radius of
the facility). You may use the site map developed under Item 3.1
to estimate the total area drained by each outfall. For areas
under 5 acres, consult your NPDES permitting authority to
determine whether the area should be reported to the nearest
tenth of an acre or nearest quarter of an acre.
Item 4.2. Provide a narrative description of the following:

Item 2.2. Briefly identify and describe each applicable project
(e.g., consent decree, enforcement order, or permit condition).
For each condition, specify the affected outfall number(s), the
source(s) of the discharge, the required final compliance date,
and the projected final compliance date.

parameters and pollutants listed in Exhibits 2F–2, 2F–3, and
2F–4 (at the end of the instructions). The instructions for
completing Tables A through D are table-specific, as are the
criteria for determining who should complete them.
Important note: Read the “General Instructions for Reporting,
Sampling, and Analysis” below before completing Items 7.2 to
7.17.
Item 7.2 and Table A. All applicants must complete Table A. If
the discharge is an existing discharge and your discharge is
composed exclusively of stormwater (i.e., no process or
nonprocess wastewater) then you only need to provide
monitoring data for oil and grease, total phosphorus, total
Kjeldahl nitrogen, and total nitrogen. Indicate “NA” for “not
applicable” in the columns for all other parameters. Answer
“Yes” to Item 7.2 once you have completed this task.
Item 7.3 and Table B. Indicate whether the facility is subject to
an effluent limitations guideline (ELG) (see 40 CFR Subchapter
N to determine which pollutants are limited in ELGs) or if the
facility is subject to effluent limitations in an NPDES permit for
its process wastewater or stormwater (if the facility is operating
under an existing NPDES permit). If yes, continue to Item 7.4. If
no, skip to Item 7.5.

Describe the treatment, including the schedule and type of
maintenance activities performed, and the ultimate disposal of
any solid or fluid wastes other than by discharge. For each
structural control identified, indicate the type of treatment the
stormwater receives using the codes in Exhibit 2F–1, at the end
of the instructions. For each non-structural control identified,
indicate “Not Applicable” in the “Codes from Exhibit 2F–1”
column.

Note: Stormwater discharges from certain industrial sources or
activities have specific ELGs for which they must comply. These
stormwater-specific ELGs include:
Regulated Discharge
Discharges resulting from spraydown or
intentional wetting of logs at wet deck storage
areas
Runoff from phosphate fertilizer manufacturing
facilities that comes into contact with any raw
materials, finished product, byproducts, or
waste products (SIC 2874)
Runoff from asphalt emulsion facilities

Section 5. Non-Stormwater Discharges
Item 5.1. Provide a certification that all outfalls that should
contain stormwater discharges associated with industrial activity
have been tested or evaluated for the presence of nonstormwater discharges. Tests for such non-stormwater
discharges can include smoke tests, fluorometric dye tests,
analysis of accurate schematics, and others.

Runoff from material storage piles at cement
manufacturing facilities
Mine dewatering discharges at crushed stone,
construction sand and gravel, or industrial sand

Item 7.10. Indicate whether you expect any of the pollutants
from Exhibit 2F–3 to be discharged in concentrations of 10 parts
per billion (ppb) or greater. If yes, continue to Item 7.11. If no,
skip to Item 7.12.

indirectly limited by an ELG through an indicator (e.g., use of
total suspended solids as an indicator to control the discharge of
iron and aluminum), you must provide data for the pollutant in
Table B. Complete one table for each outfall. Answer “Yes” to
Item 7.4 once you have completed this task.

Item 7.11. Provide quantitative data in Table C for those
pollutants in Exhibit 2F–3 that you expect to be discharged in
concentrations of 10 ppb or greater (provide actual data for
existing dischargers and estimated data for new sources and
new dischargers). Answer “Yes” to Item 7.11 once you have
completed this task.

Item 7.5 and Table C. Table C requires you to address the
pollutants in Exhibits 2F–2, 2F–3, and 2F–4 for each outfall.
Pollutants in each of these exhibits are addressed differently.
Indicate whether you know or have reason to believe any
pollutants in Exhibit 2F–2 are present in the discharge. If yes,
continue to Item 7.6. If no, skip to Item 7.7.

Item 7.12. Indicate whether you expect acrolein, acrylonitrile,
2,4-dinitrophenol, or 2-methyl-4,6-dinitrophenol to be discharged
in concentrations of 100 ppb or greater. If yes, continue to Item
7.13. If no, skip to Item 7.14.

Item 7.6. For each outfall, list all pollutants in Exhibit 2F–2 that
you know or have reason to believe are present in the discharge
in Table C (except pollutants previously listed in Table B that are
limited directly or indirectly by an ELG) and either report
quantitative data or briefly describe the reasons the pollutant is
expected to be discharged. Answer “Yes” to Item 7.6 once you
have completed this task.

Item 7.13. Provide quantitative data in Table C for the pollutants
identified in Item 7.12 that you expect to be discharged in
concentrations of 100 ppb or greater (provide actual data for
existing dischargers and estimated data for new sources and
new dischargers). Answer “Yes” to Item 7.13 once you have
completed this task.

Item 7.7. This item asks if you qualify as a “small business.” If
so, you are exempt from the reporting requirements for the
organic toxic pollutants listed in Exhibit 2F–3.

Item 7.14. For any pollutants you expect to be present in the
discharge at concentrations less than 10 ppb (or less than
100 ppb for the above four pollutants), either submit quantitative
data or briefly describe the reasons the pollutant is expected to
be discharged in Table C. Answer “Yes” to Item 7.14 once you
have completed this task.

You can qualify as a small business in two ways: (1) if your
facility is a coal mine and if your probable total annual
production is less than 100,000 tons per year, you may submit
past production data or estimated future production (such as a
schedule of estimated total production under 30 CFR 795.14(c))
instead of conducting analyses for the organic toxic pollutants;
(2) if your facility is not a coal mine and if your gross total annual
sales for the most recent three years average less than
$100,000 per year (in second quarter 1980 dollars), you may
submit sales data for those years instead of conducting
analyses for the organic toxic pollutants. The production or sales
data must be for the facility that is the source of the discharge.
The data should not be limited to production or sales for the
process or processes that contribute to the discharge, unless
those are the only processes at your facility. For sales data, in
situations involving intra-corporate transfer of goods and
services, the transfer price per unit should approximate market
prices for those goods and services as closely as possible.
Sales figures for years after 1980 should be indexed to the
second quarter of 1980 by using the gross national product price
deflator (second quarter of 1980 = 100). This index is available
online from the U.S. Department of Commerce, Bureau of
Economic Analysis, at
https://apps.bea.gov/national/pdf/SNTables.pdf.

Item 7.15. Indicate whether you know or have reason to believe
any pollutants in Exhibit 2F–4 are present in the discharge. If
yes, continue to Item 7.16. If no, skip to Item 7.17.
Item 7.16. For each outfall, list any pollutant in Exhibit 2F–4 that
you know or believe to be present in the discharge in Table C
and explain why you believe it to be present. No analysis is
required, but if you have analytical data, you must report it.
Answer “Yes” to Item 7.16 once you have completed this task.
Note: Under 40 CFR 117.12(a)(2), certain discharges of hazardous
substances (listed in Exhibit 2F–5) may be exempted from the
requirements of CWA Section 311, which establishes reporting
requirements, civil penalties, and liability for cleanup costs for spills
of oil and hazardous substances. A discharge of a particular
substance can be exempted if the origin, source, and amount of the
discharged substances are identified in the NPDES permit
application or in the permit, if the permit contains a requirement for
treatment of the discharge, and if the treatment is in place. If you
would like to apply for an exemption from the requirements of CWA
Section 311, attach additional sheets of paper to your application,
setting forth the following information:

If you qualify as a small business according to the criteria
above, answer “Yes” to Item 7.7 and skip to Item 7.18.
Otherwise, answer “No” and continue to Item 7.8.

1. The substance and the amount of each substance that might be
discharged.
2. The origin and source of the discharge of the substance.
3. The treatment to be provided for the discharge by:
a. An onsite treatment system separate from any treatment
system treating your normal discharge;
b. A treatment system designed to treat your normal discharge
and that is additionally capable of treating the amount of the
substance identified under paragraph 1 above; or

Item 7.8. Indicate whether you know or have reason to believe
any pollutants in Exhibit 2F–3 are present in the discharge. If
yes, continue to Item 7.9. If no, skip to Item 7.10.
Item 7.9. For each outfall, list all pollutants in Exhibit 2F–3 that
you know or have reason to believe are present in the discharge
in Table C (except pollutants previously listed in Table B).

General Instructions for Reporting, Sampling, and Analysis
Important note: Read these instructions before completing
Tables A through C and Section 7 of Form 2F.

Base your determination that a pollutant is/will be present in your
discharge on your knowledge of the facility’s raw materials,
material management practices, maintenance chemicals, history
of spills and releases, intermediate and final products and
byproducts, and any previous analyses known to you of your
effluent or similar effluent.

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 table page and any associated attachments.

Sampling

You may report some or all of the required data by attaching
separate sheets of paper instead of completing Tables A through
C for each of your outfalls so long as the sheets contain all of the
required information and are similar in format to Tables A through
C. For example, you may be able to print a report in a compatible
format from the data system used in your gas chromatography/
mass spectrometry (GC/MS) analysis completed under Table B.
If you are an existing discharger, you are required to report actual
quantitative data. See “Use of Historical Data” below for use of
historical data. If you are a new source or discharge, you may
supply estimated data along with the source of each estimate. If
you have quantitative data available, however, you must provide
it. Base estimates on available in-house or contractor engineering
reports or any other studies performed on the proposed facility.
Use the following codes to report your source information in the
“Source of Information” column:

No later than 24 months after your facility commences to
discharge, you must complete and submit sampling and analysis
data for the pollutants and parameters in Tables A through C.
However, you need not report results for tests you have already
performed and reported under the discharge monitoring
requirements of your NPDES permit.
Table A requires you to report at least one analysis for each
pollutant listed. Tables B and C require you to report analytical
data in two ways. For some pollutants addressed in Tables B and
C, if you know or have reason to know that the pollutant is
present in your discharge, you may be required to list the
pollutant and test (sample and analyze) and report the levels of
the pollutants in your discharge. For all other pollutants
addressed in Tables B and C, you must list the pollutant if you
know or have reason to know that it is present in the discharge;
you must also either report quantitative data for the pollutant or
briefly describe the reasons it is expected to be discharged. (See
Items 7.2 through 7.17 of the instructions for completing Tables A
through C.)

The collection of the samples for the reported analyses should be
supervised by a person experienced in performing sampling of
industrial wastewater or stormwater discharges. 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 analytical methods—for example, sample
containers, sample preservation, holding times, and the collection
of duplicate samples—must be followed.
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.
Grab samples must be taken in the first 30 minutes of discharge
(or as soon thereafter as practicable) for pH, temperature,
cyanide, total phenols, residual chlorine, oil and grease, fecal
coliform (including E. coli) and enterococci (previously known as
fecal streptococcus at 40 CFR 122.26(d)(2)(iii)(A)(3)), and volatile
organic compounds. You are not required to analyze a flowweighted composite for these parameters.
For all other pollutants, both a grab sample collected during the
first 30 minutes (or as soon thereafter as practicable) of the
discharge and a flow-weighted composite sample must be
analyzed. However, a minimum of one grab sample may be taken
for effluents from holding ponds or other impoundments with a
retention period of greater than 24 hours.
All samples must be collected from the discharge resulting from a
storm event that is greater than 0.1 inches and at least 72 hours
from the previously measurable (greater than 0.1 inch rainfall)
storm event. Where feasible, the variance in the duration of the
event and the total rainfall of the event should not exceed 50
percent from the average or median rainfall event in that area.
A grab sample must be taken during the first 30 minutes of the
discharge (or as soon thereafter as practicable), and a flowweighted composite must be taken for the entire event or for the
first three hours of the event.
Grab and composite samples are defined as follows:
Grab sample: An individual sample of at least 100 milliliters
collected during the first 30 minutes (or as soon thereafter as
practicable) of the discharge. This sample is to be analyzed
separately from the composite sample.

2F-6

FORM 2F—INSTRUCTIONS (CONTINUED)
General Instructions for Reporting, Sampling, and Analysis Continued
Flow-weighted composite sample: A flow-weighted composite
sample may be taken with a continuous sampler that proportions
the amount of sample collected with the flow rate or as a
combination of a minimum of three sample aliquots taken in each
hour of discharge for the entire event or for the first three hours of
the event, with each aliquot being at least 100 milliliters and
collected with a minimum period of 15 minutes between aliquot
collections. The composite must be flow proportional; the time
interval between either each aliquot or the volume of each aliquot
must be proportional to either the stream (effluent) flow at the
time of sampling or the total stream (effluent) flow since the
collection of the previous aliquot. Aliquots may be collected
manually or automatically. Where GC/MS volatile organic
analysis is required, aliquots must be combined in the laboratory
immediately before analysis. Only one analysis for the composite
sample is required.
Use of Historical Data
Existing data may be used, if available, in lieu of sampling
conducted solely for the purposes of this application, provided
they are representative of the present discharge and were
collected within 3 years of the application due date. If you sample
for a listed pollutant on a monthly or more frequent basis,
summarize the data collected within one year of the application
for the pollutant(s) at issue.
Among the factors that would cause the data to be
unrepresentative are significant changes in production level;
changes in raw materials, processes, or final products; and
changes in stormwater treatment. The NPDES permitting
authority may request additional information, including current
quantitative data, if they determine it to be necessary to assess
your discharges. The NPDES permitting authority may allow or
establish appropriate site-specific sampling procedures or
requirements including sampling locations, the season in which
the sampling takes place, the minimum duration between the
previous measurable storm event and the storm event sampled,
the minimum or maximum level of precipitation required for an
appropriate storm event, the form of precipitation sampled (snow
melt or rainfall), protocols for collecting samples under 40 CFR
136, and additional time for submitting data on a case-by-case
basis.
Reporting
Report sampling results for all pollutants in Tables A through C
as concentration and mass, with the exception of flow,
temperature, pH, color, and fecal coliform organisms.
Flow, temperature, pH, color, and fecal coliform organisms must
be reported as million gallons per day (mgd), degrees Celsius
(°C), standard units, color units, and most probable number per
100 milliliters (MPN/100 mL), respectively. Use the following
abbreviations in the columns requiring “units” in Tables A
through C.

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)

All reporting of values for metals must be in terms of “total
recoverable metal” unless:
•

An applicable, promulgated ELG specifies the limitation for
the metal in dissolved, valent, or total form;

•

All approved analytical methods for the metal inherently
measure only its dissolved form (e.g., hexavalent chromium);
or

•

The NPDES permitting authority has determined that in
establishing case-by-case limitations it is necessary to
express the limitations of the metal in dissolved, valent, or
total form to carry out the provisions of the CWA.

If you measure only one grab sample and one flow-weighted
composite sample for a given outfall, complete only the “Maximum
Daily Discharge” columns in the tables and enter “1” in the
“Number of Storm Events Sampled” column. The NPDES
permitting authority may require you to conduct additional
analyses to further characterize your discharges.
If you measure more than one value for a grab sample or a flowweighted composite sample for a given outfall and those values
are representative of your discharge, you must report them. You
must describe your method of testing and analysis.
The “Average Daily Discharge” column in Tables A to C is not
compulsory but should be filled out if data are available. To
complete the “Average Daily Discharge” column, determine the
average of all values within the last year and report the
concentration and mass. Report the total number of storm events
sampled under the “Number of Storm Events Sampled” column.
Substantially Identical Outfalls
If you have two or more substantially identical outfalls, you may
request permission from your NPDES permitting authority to
sample and analyze only one outfall and submit the results of the
analysis for all substantially identical outfalls. If your request is
granted, submit the following information on a separate sheet
attached to the application form: the identity of the outfall you did
test and an explanation of how it is substantially identical to the
outfall(s) that you did not test.

2F-7

FORM 2F—INSTRUCTIONS (CONTINUED)
General Instructions for Reporting, Sampling, and Analysis Continued
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.
