Note: Complete this form if your facility is a new or existing publicly owned treatment works.

Paperwork Reduction Act Notice
The U.S. Environmental Protection Agency estimates the average burden to collect information and
complete Form 2A to average between 4.7 and 24.7 hours, depending on the number of sections the
applicant must complete. The estimate includes time for reviewing instructions, searching existing data
sources, gathering and maintaining the needed data, and completing and reviewing the collection of
information. Send comments about the burden estimate or any other aspect of this collection of
information to the Chief, Information Policy Branch (PM-223), U.S. Environmental Protection Agency,
1200 Pennsylvania Avenue, NW, Washington, DC 20460, and to the Office of Information and
Regulatory Affairs, Office of Management and Budget, 725 17th Street, NW, Washington, DC 20503,
marked "Attention: Desk Officer for EPA."

FORM 2A—GENERAL INSTRUCTIONS
Who Must Complete Form 2A?
All new and existing publicly owned treatment works (POTWs) and
other dischargers designated by the National Pollutant Discharge
Elimination System (NPDES) permitting authority must complete
Form 2A. Note that you may wish to consult the "General
Instructions" of NPDES Application Form 1 to determine if your
treatment works is required to submit any additional NPDES
application forms.
At the state level, either the U.S. Environmental Protection Agency
(EPA) or an approved state agency administers the NPDES permit
program. If you are located in a jurisdiction in which an EPA
regional office administers the NPDES permit program, you should
use Form 2A and all other applicable forms described in these
instructions. If you are located in a jurisdiction where a state
administers the NPDES permit program, contact the state to
determine the forms you should complete. States often develop
their own application forms rather than use the federal forms. See
http://www.epa.gov/npdes/npdes-state-program-information for a
list of states that have approved NPDES permit programs and
those that do not.
Exhibit 2A-1 (see end of this section) provides contact information
for each of EPA's 10 regional offices. Since the exhibit's content is
subject to change, consult EPA's website for the latest information:
http://www.epa.gov/aboutepa#regional.
Where to File Your Completed Form
• If you are in a jurisdiction with an approved state NPDES
permit program, file according to the instructions on the state
forms.
• If you are in a jurisdiction where EPA is the NPDES permitting
authority (i.e., the state is not an NPDES-authorized state),
mail the completed application forms to the EPA regional office
that covers the state in which your facility is located (see
Exhibit 2A-1).
When to File Your Completed Form
Form 2A must be submitted at least 180 days before your present
NPDES permit expires or, if you are a new discharger, at least
180 days before the date on which the discharge is to commence,
unless the NPDES permitting authority has granted permission for a
later date.
Fees
EPA does not require applicants to pay a fee for applying for
NPDES permits. However, states that administer the NPDES permit
program may charge fees. Consult with state officials for further
information.
Public Availability of Submitted Information
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 2A (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 2A. 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 the Agency's business confidentiality regulations
at Part 2 of Title 4 of the Code of Federal Regulations (CFR).
Completion of Forms
Form 2A is divided into six major sections. It also contains five
effluent monitoring tables (Tables A through E) and an industrial
discharge information table (Table F), all located at the end of the
form. Note that not all applicants are required to complete each
section of the form or all of the tables. The questions on the form
will direct you to the items and tables you must complete.
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.
Provide your EPA Identification Number from the Facility Registry
Service, NPDES permit number, and facility name at the top of
each page of Form 2A and any attachments. If your facility is new
(i.e., not yet constructed), write or type "New Facility" in the space
provided for the EPA Identification Number and NPDES permit
number. If you do not know your EPA Identification Number,
contact your NPDES permitting authority. See Exhibit 2A-1 for
contact information. Additionally, for Tables A through E, provide
the applicable outfall number at the top of each page.
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.
If you have previously submitted information that answers a specific
question to EPA or an approved state NPDES agency, you may
either repeat the information in the space provided or attach a copy
of the previous submission.
Note for New Dischargers
Provide all information available to you at the time you
complete Form 2A. If you do not have information to respond
to an item because your facility has yet to discharge, write or
type "data are not available" next to the item on the form. Note
that you are required to submit actual data no later than
24 months after your facility commences to discharge.
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 the various NPDES
application forms are included in the "Glossary" at the end of these
instructions.

process wastewater to the treatment works (with
certain exclusions); or
ii. Contributes a process wastestream that makes up
5 percent or more of the average dry weather
hydraulic or organic capacity of the treatment plant;
or
iii. Is designated as an SIU by the control authority.
The control authority may determine that an Industrial User
subject to categorical Pretreatment Standards under 40 CFR
403.6 and 40 CFR Chapter I, Subchapter N is a NSCIU rather
than a SIU on a finding that the Industrial User never
discharges more than 100 gpd of total categorical wastewater
(excluding sanitary, non -contact cooling and boiler blowdown
wastewater, unless specifically included in the Pretreatment
Standard) and the following conditions are met:
a. The Industrial User, prior to the control authority's finding,
has consistently complied with all applicable categorical
Pretreatment Standards and Requirements;
b. The Industrial User annually submits the certification
statement required in 40 CFR 403.12(q) together with any
additional information necessary to support the
certification statement; and
c. The Industrial User never discharges any untreated
concentrated wastewater.
Item 4.2. Indicate the number of SIUs and NSCIUs that discharge
to the POTW.
Item 4.3. Answer whether the POTW has an approved
pretreatment program, which is defined at 40 CFR 403.3 as a

General Instructions for Reportinq, Samplinq, and Analvsis
Important note: Read these instructions before completing
Tables A through E and Section 3 of Form 2A.
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 the tables and any associated attachments.
You may report some or all of the required data by attaching
separate sheets of paper instead of completing Tables A through
E 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
E. For example, you may be able to print a report in a compatible
format from the data system used in your analysis of metals
completed under Table C.
Note for new dischargers. Provide all information available to
you at the time you complete Form 2A. If you do not have
information to respond to an item because your facility has yet to
discharge, write or type "data are not available" next to the item
on the form. Note that you are required to submit actual data no
later than 24 months after your facility commences discharge.
Reporting of Effluent Data
Where effluent data are requested, do not provide information on
CSOs. The latter information is requested instead under Section 5
of Form 2A.
Provide data for each outfall through which effluent is discharged.
When an applicant has two or more outfalls with substantially
identical effluents, the NPDES permitting authority may allow the
applicant to test only one outfall and report that quantitative data
as applying to the substantially identical outfall. If the permitting
authority grants your request, attach a separate sheet to the
application form identifying the outfall tested and describing why
the other outfall(s) are substantially identical.
At a minimum, effluent testing data must be based on at least
three samples taken within 4.5 years prior to the date of the
permit application. Samples must be representative of the
seasonal variation in the discharge from each outfall. Existing
data may be used, if available, in lieu of sampling done solely for
the purpose of this application.
All existing data for pollutants specified in Tables A through D that
is collected within 4.5 years of the application must be included in
the pollutant data summary that you submit. If, however, you
sampled for a specific pollutant on a monthly or more frequent
basis, it is only necessary, for such pollutant, to summarize all
data collected within 1 year of the application.
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 0. 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 0, for the measured pollutant or
pollutant parameter.
Consistent with 40 CFR 136, you may provide matrix- or sample -
specific 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 0,
and is not 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, other factors
such as a method's precision, accuracy, or resolution, may be
considered when assessing the performance of the method.
Effluent monitoring data must comply with the QA/QC
requirements of 40 CFR 136 (and other appropriate QA/QC
requirements for standard methods for analytes not addressed by
40 CFR 136).
Clearly specify the units of measure on Tables A through E for
each parameter/pollutant analyzed. Values should be reported as
concentration or mass, except for flow, temperature, pH, color,
and fecal coliform organisms, unless otherwise requested or
required by the NPDES permitting authority. Flow, temperature,
pH, color, and fecal coliform organisms must be reported as mgd,
degrees Celsius (°C), standard units, color units, and most
probable number per 100 milliliters (MPN/100 mQ, respectively.
Use the following abbreviations in the columns requiring "units" in
Tables A through D.
Concentration
Mass
ppm = parts per million
Ibs = pounds
mg/L = milligrams per liter
ton = tons (English tons)
ppb = parts per billion
mg = milligrams
pg/L = micrograms per liter

FORM 2A—GLOSSARY CONTINUED
DAILY DISCHARGE means the "discharge of a pollutant" measured during a calendar day or any 24-hour period that reasonably
represents the calendar day for purposes of sampling. For pollutants with limitations expressed in units of mass, the "daily discharge" is
calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of
measurement, the "daily discharge" is calculated as the average measurement of the pollutant over the day.
DIRECT DISCHARGE means the "discharge of a pollutant."
DIRECTOR means the Regional Administrator or the State Director, as the context requires, or an authorized representative. When there
is no "approved State program," and there is an EPA administered program, "Director" means the Regional Administrator. When there is
an approved State program, "Director" normally means the State Director. In some circumstances, however, EPA retains the authority to
take certain actions even when there is an approved State program. (For example, when EPA has issued an NPDES permit prior to the
approval of a State program, EPA may retain jurisdiction over that permit after program approval, see § 123.1.) In such cases, the term
"Director" means the Regional Administrator and not the State Director.
DISCHARGE (OF A POLLUTANT) means:
• Any addition of any pollutant or combination of pollutants to waters of the United States from any point source; or
• Any addition of any pollutant or combination of pollutants to the waters of the contiguous zone or the ocean from any point source
other than a vessel or other floating craft which is being used as a means of transportation.
This definition includes discharges into waters of the United States from: surface runoff which is collected or channelled by man;
discharges through pipes, sewers, or other conveyances owned by a State, municipality, or other person which do not lead to a treatment
works; and discharges through pipes, sewers, or other conveyances, leading into privately owned treatment works. This term does not
include an addition of pollutants by any "indirect discharger".
DISCHARGE MONITORING REPORT means the EPA uniform national form, including any subsequent additions, revisions, or
modifications for the reporting of self -monitoring results by permittees. DMRs must be used by "approved States" as well as by EPA. EPA
will supply DMRs to any approved State upon request. The EPA national forms may be modified to substitute the state agency name,
address, logo, and other similar information, as appropriate, in place of EPA's.
DRAFT PERMIT means a document prepared under § 124.6 indicating the Director's tentative decision to issue or deny, modify, revoke
and reissue, terminate, or reissue a "permit." A notice of intent to terminate a permit, and a notice of intent to deny a permit, as discussed
in § 124.5, are types of "draft permits." A denial of a request for modification, revocation and reissuance, or termination, as discussed in
§ 124.5, is not a "draft permit." A "proposed permit" is not a "draft permit."
EFFLUENT LIMITATION means any restriction imposed by the Director on quantities, discharge rates, and concentrations of "pollutants"
which are "discharged" from "point sources" into "waters of the United States," the waters of the "contiguous zone," or the ocean.
EFFLUENT LIMITATIONS GUIDELINES means a regulation published by the Administrator under section 304(b) of the CWA to adopt or
revise "effluent limitations."
ENVIRONMENTAL PROTECTION AGENCY (EPA) means the United States Environmental Protection Agency.
FACILITY or ACTIVITY means any NPDES "point source" or any other facility or activity (including land or appurtenances thereto) that is
subject to regulation under the NPDES program.
GENERAL PERMIT means an NPDES "permit" issued under § 122.28 authorizing a category of discharges under the CWA within a
geographical area.
HAZARDOUS SUBSTANCE means any substance designated under 40 CFR part 116 pursuant to section 311 of the CWA.
INDIAN COUNTRY (or INDAN LANDS) means:
• All land within the limits of any Indian reservation under the jurisdiction of the United States Government, notwithstanding the
issuance of any patent, and, including rights -of -way running through the reservation;
• All dependent Indian communities with the borders of the United States whether within the originally or subsequently acquired territory
