L INTRODUCTION
Under the National Pollutant Discharge Elimination
System (NPDES), the Environmental Protection
Agency (EPA) has issued general pennits for storm
water discharges associated with industrial activity in
States and territories mat have not been delegated
NPDES permitting authority. See Exhibit 1-1 on the
opposite page for a list of these locations. The
pennits were published on September 9 and
September 25, 1992, in the Federal Register (57 FR
41297 and 57 FR 44438).
The permits require certain categories of facilities to
report semi-annual monitoring results for storm water
discharges. This booklet:
• clarifies which industrial activities are required
to report their storm water discharge monitoring
results (Section 2.1);
• identifies the parameters to be monitored, and
when and where to report (Sections 2.1, 2.2);
• provides instructions on how to record
monitoring results on a Discharge Monitoring
Report (DMR) (Section 3); and
• lists additional State-specific requirements that
facilities, depending on where they are located.
must meet in addition to the EPA requirements
in preceding sections (Section 4).
If you have any questions regarding the storm water
program, please call your permitting authority.
Permitting authority addresses and phone numbers are
listed in Part 5 of this guidance. If you would like to
obtain guidance on procedural methods for conducting
storm water sampling, the guidance manual titled
NPDES Storm Water Sampling Guidance Document
(EPA #833-8-92-001, July, 1992) can be obtained by
contacting the EPA Office of Water Resources Center
at (202)260-7786.
This booklet will be revised and expanded as
necessary to reflect changes in the reporting
requirements in storm water general permits.

2. GENERAL INFORMATION
This section reviews the requirements for reporting
semi-annual monitoring results in EPA's storm water
general pennits. The numbers in brackets below refer
to the section of the general pennits in which the
requirement can be found. In addition to the
requirements listed in this section, facilities must
comply with specific State and Regional requirements,
which can be found in Section 4 of these instructions.
For more details, please refer to the State and Region
specific requirements in the permit under which the
facility is covered (Section XI in 57 FR 41297 and 57
FR 44438).
2.1 MONITORING REQUIREMENTS
Faculties That Must Report Semi-Annual
Monitoring Results
Certain storm water discharges from the industrial
activities listed below must be monitored twice per
year, with the results reported annually (see Exhibit 2-
1 for monitoring periods and reporting dates). If a
facility has storm water discharges associated with
industrial activity from multiple and separate
activities, only those discharges where the
requirements apply must be monitored.
• Section 313 of Emergency Planning and
Right to Know Act (EPCRA
facilities:
Storm water that is discharged from the facility
that comes into contact with any equipment,
tank, container or other vessel or area used for
storage of a Section 313 water priority chemical,
or located at "a truck or rail car loading or
unloading area where a Section 313 water
priority chemical is handled. [Pan VI.B.2.a]
Wood
facilities:
Storm water discharges from areas mat are used
for wood treatment, wood surface application or
storage of treated or surface-protected wood at
any wood preserving or wood surface facilities.
[Part VLB2.d]
NPDES Storm Water General Permit DMR Guidance
Page 2
-------
Discharges Under More Than One Category
Facilities with discharges that fall under more than
one reporting category, where the discharges are co-
mingled, must monitor and report by the earliest
applicable date and then annually by that date. If
discharges under different categories are not co-
mingled, then monitoring and repotting can be
performed either together, according to the earliest
date, or separately according to the dates for the
applicable categories. (Coal pile runoff may not be
commingled prior to sampling because of the effluent
limitations contained in the permits - see Section 3.1
of these instructions.) [Pans VI.B.2.a-f, VI.D.l.a-d]
How to Report
A separate DMR form is required for each storm
event and for each outfall sampled. DMRs must be
signed and mailed to the appropriate EPA Region,
and must be postmarked by the date specified in
Exhibit 2-1. The permittee should retain a copy. See
Section S for a list of Regional mailing addresses and
phone numbers. [Pan VI.D.l]
Substantially Identical Discharges
If there is reason to believe that the discharges fror
two or more outfalls are substantially identical, one c
the outfalls may be monitored and that data submitted
for an substantially identical outfalls. A description
of the location of the outfalls, an explanation of why
the outfalls have substantially identical discharges,
and the size of the drainage area and runoff
coefficient must be submitted as an attachment to the
DMR. [Part VLB.6]

Primary
industries:
Stonn water discharges from industrial activities
classified as Standard Industrial Classification
(SIC) 33. [Part VI.B.2.b]
• Coal piles:
Coal pile runoff. [Pan VLB.2.e]
• Battery reclaimers:
Storm water discharges from areas used for
storage of lead acid batteries, reclamation
products, or waste products, and areas used for
lead acid battery reclamation. [Pan VI.B.2.f]
• Land disposal units/Indnerators/Boilers and
Industrial Furnaces (BEFs):
Storm water discharges from any active or
inactive landfill, land application sites, or open
dumps without a stabilized final cover that has
received any industrial wastes (other than wastes
from a construction site) and incinerators,
including BIFs that bum hazardous waste and
operate under interim status or a permit under
Subtitle C of RCRA. [Part VI.B.2.C]
Parameters to Monitor
Exhibit 2-2 lists the specific parameters (pollutants)
that must be monitored for each industrial category.
If more than one of these categories applies to a
particular discharge, the discharge must be monitored
for all parameters listed in each category. [Parts
VI.B.2.a-f]
WET Test Alternative
Facilities that must monitor for whole effluent toxicity
(WET), instead may monitor for those pollutants
identified in Tables II and in of Appendix D of 40
CFR 122 (see Exhibit 2-3) that are known or believed
to be present at the facility. Facilities should
determine which of these pollutants may be present in
or absent from the discharge through a reasonable
best effort to identify significant quantities of
materials or chemicals present at the facility. [Pan
VI.B.8]
Storm Event Characteristics
The following information must be provided on the
DMR for the storm event that produced the discharge:
• the date and duration of the storm,
• the duration between the storm sampled and the
end of the previous measurable storm of greater
than 0.1 inch,
• a measurement or estimate of the amount of
rainfall Qn inches), and
• an estimate of the total volume of the discharge
sampled (in gallons). [Pan VLB .2]
Adverse Weather Waiver
If samples cannot be collected due to adverse weather
conditions, a description of why samples could not be
collected must be submitted in lieu of a DMR. A
waiver because of adverse weather cannot be
submitted more than once in any two-year period.
[Pan VI.B.5]
Exemption to Monitoring Requirements
As an alternative to monitoring an outfall, an annual
certification may be made that material handling
equipment or activities; raw or waste materials;
intermediate, final, or by-products; industrial
machinery or operations; and significant materials
from past activity are not presently exposed to storm
water and win not be exposed for one year. The
certification should be made at the start of each one-
year reporting period and kept with the facility's
storm water pollution prevention plan. This
certification is then submitted in lieu of the DMR at
the appropriate time (see Exhibit 2-1). [Pan VI.B.7]
2.2 REPORTING REQUIREMENTS
When to Monitor and Report
Samples must be collected and analyzed at least once
during each six-month monitoring period. Monitoring
results must be submitted annually. See Exhibit 2-1
for monitoring periods and reporting dates. Results
do not have to be submitted until the facility has been
covered by the permit for a full 6-month monitoring
period. [Parts VI.B^.a-f, VI.D.l.a-c]
More Frequent Monitoring
If sampling is conducted more frequently than semi-
annually, ajl sampling results must be submitted. A
separate DMR is required for each storm event
sampled. [Part VI.D.l.a-c]

3. STEP-BY-STEP
INSTRUCTIONS FOR
RECORDING MONITORING
RESULTS
Please read Sections 2 and 3, and refer to the
additional State-specific requirements in Section 4,
prior to recording monitoring results on a DMR.
When following these step-by-step instructions, refer
to the sample DMR for guidance (Exhibit 3-1). The
words and phrases in italics in the following step-by-
step instructions refer to specific locations or headings
on the DMR. The steps are identified on the sample
by the step number enclosed in a circle.
3.1 PREPARING A DMR
(If more than one page is needed to record monitoring
results, enter the information for Steps I, 2, 3, 4, 5,
and 13 on every page. Remember that a separate
DMR is required for each storm event and each
outfall sampled.)
1) Name/Address
Enter the Permittee Name/Mailing Address and
Facility Name/Location, if different.
2) Permit Number
Enter the Permit Number for your facility. The
permit number is the unique number assigned
specifically to your facility for coverage under a
storm water general permit Your facility's permit
number can be found in the letter you received
confirming that your facility is covered by the permit
3) Discharge Number
If you are submitting monitoring results for more than
one outfall, you must record die outfall's Discharge
Number. You must assign a unique discharge number
(e.g.. 001,002, etc.) to each outfalL It is appropriate
to assign each outfall the same number it is assigned
in your facility's storm water pollution prevention
plan. If the facility has existing NPDES permits for
other outfalls, do not duplicate outfall numbers.
Rather, begin with the number following the last one
assigned in your existing permit If you believe that
the discharges from your facility's outfalls are
substantially identical, please see Substantially
Identical Outfalls in Section 2.2.
4) Monitoring Period
Under Monitoring Period, enter dates for the
beginning and end of the six-month period covered by
the DMR (see Exhibit 2-1).
5) Discharge Category
In the top right comer of the form, indicate the
category or categories for the discharge that was
sampled (i.e., Section 313 EPCRA, primary metal,
etc.).
6) Storm Event Characteristics
Use the first line to record the required storm
information. Under Parameter, enter the date and
duration of the storm, and the time elapsed since the
last measurable storm greater than 0.1 inch.
Under Quantity or Loading, enter in the Maximum
column die rainfall measurement or estimate for the
storm that generated the discharge.
Under Quality or Concentration, enter in the
Maximum column an estimate of the total volume o
the flow through the outfall.
The rainfall estimate should be in inches and the
volume estimate should be in gallons. Record the
units that were used in the Units columns.
7) Sample Type
For discharges from holding ponds or other
impoundments with a retention period greater than 24
hours, a minimum of one grab sample may be taken
for all parameters.
For all other discharges, both a grab sample and a
composite sample must be collected and analyzed for
all parameters except the following five (for which
only a grab sample is required):
pH,
cyanide,
whole effluent toxicity,
fecal coliform. and
oil and grease.
NPDES Storm Water General Permit DMR Guidance
Page?
-------
Please note that you only have to monitor for those
parameters listed in your permit (see Exhibit 2-2 and
Section 4).
All samples must be collected from a discharge
resulting from a storm of greater than 0.1 inch in
rainfall and that occurs at least 72 hours after the
previous storm of 0.1 inch or more. Grab samples
must be taken during the first 30 minutes of the
discharge, unless impracticable, in which case a grab
sample may be taken during ale first hour. If the
grab sample is not taken during the first 30 minutes,
an explanation of why this was not possible must be
submitted with the DMR.
8) Parameters - Sampled Pollutants
Enter each parameter as specified in the monitoring
requirements of your permit (see Exhibit 2-2 and
Section 4). One line is needed for each sample type.
Therefore, to report results for both grab and
composite samples of the same parameter, use two
lines.
9) Recording of Sample Results
Enter the monitoring results for each parameter
according to the following format Under Quality or
Concentration, record grab sample results in the
Maximum column and record composite sample
results in the Average column. Remember to use one
line for each sample type.
Under the Sample Type column, record the type of
sample used for the analysis. Record "O" for a grab
sample, and "C" for a composite sample. For
composite samples, indicate if the results are from a
flow-weighted (F) or time-weighted (T) composite.
Also, record the units used in the Units column.
10) Effluent Limitations
The only non-State specific effluent limitations listed
in EPA's general permits are for coal pile runoff.
The effluent limitations for coal pile runoff are: a
maximum concentration at any time of 50 mg/l total
suspended solids (TSS) and a pH within the range of
6.0 - 9.0 standard units. Compliance with these
effluent limitations must be achieved no later man
October 1, 1995.
To report monitoring results for parameters where
effluent limitations apply, enter the limitation as the
Permit Requirement under Quality or Concentration.
Under the No. Ex column, enter a "r* if the sample
measurement during the monitoring period exceeded
the effluent limitation for that parameter. Otherwise,
leave the space blank.
11) State-Specific Effluent Limitations
State-specific effluent limitations also may apply to
your discharges (see Section 4). If your permit
contains State-specific effluent limitations that apply
to the discharge, enter the limitations using the
instructions hi the second paragraph of step 10. (No
State-specific effluent limitations are shown on the
sample DMR.)
12) Biomonitoring Results
If a whole, effluent toxicity (WET) test is conducted,
all of the test organisms, procedures, and quality
assurance criteria that are used must be in accordance
with the following EPA guidance manual: Methods
for Measuring the Acute Toxicitv of Effluents and
Receiving Waters to Freshwater and Marine
Organisms (EPA/600/4-90-027, revised September,
1991).
For WET results, if there is no statistical difference
between the control mortality and the effluent
mortality (no dilution), report a "0" in the Maximum
column under Quality or Concentration, If there is a
statistical difference between the control mortality and
the effluent mortality, report a "1" in the Maximum
column under Quality or Concentration. (No WET
test results are shown on the sample DMR.)
13) Identification/Certification
Enter Name/Title of Principal Executive Officer,
Signature of Principal Executive Officer or Authorized
Agent, Telephone Number, and Date at the bottom of
each page of the DMR after reading the Certification
Statement.
14) Mailing the DMR
Send the completed DMRs to the appropriate EPA
Regional mailing address (see Section 5). Please
make sure to provide adequate postage.

4. STATE-SPECIFIC
REQUIREMENTS
In addition to following the instructions discussed in
Sections 2 and 3, dischargers in the States below must
comply with die following special monitoring and
reporting requirements. (Please see Part XI of your
permit for more specific details.) Please note that the
conditions outlined in this guidance document are
applicable only to facilities covered by EPA-issued
permits (see Exhibit 1-1).- If you are located in a
NPDES-authorized State, you must consult vour
State-specific storm water general permit or vour
State permitting authority for specific permit
conditions.
4.1 EPA REGION I
4.1.1 MAINE
Whole Effluent Toxicitv (WED Test Procedures:
The discharge will not lower the quality of the
receiving waters below the minimum requirements of
their classification and will satisfy the appropriate
requirements of Maine law provided that the test
organisms include ceriodaphnia and brook trout,
salvelinus fontinalis, to meet the WET requirements
for storm water discharges associated with industrial
activity.
4.2 EPA REGION U
42.1 PUERTO RICO
Additional Parameters: Permittees must install a rain
gauge and keep daily records of the amount of
rainfall. A copy of these records must be submitted
on the 28th days of January, April, July, and October,
and shall be attached to the DMR where appropriate.
Storm Characteristic Data:
• In addition to the required storm characteristic
data, permittees must provide an estimate of the
size of the drainage area On square feet); and an
estimate of the runoff coefficient of the drainage
area [e.g., low (under 40%), medium (40% to
65%), or high (above 65%)]. (Facilities subject
to Section 313 of EPCRA and land disposal
units/incinerators/BIFs are not subject to tiu>
requirement.) This information should b
included in the attachment containing the rain
gauge report
• Permittees subject to annual monitoring
requirements are not required to provide an
estimate of the total volume (in gallons) of the
discharge sampled.
Sample Type: For data reported in a grab sample and
a composite sample:
• 'For the first half of the sampling period, all
samples shall be collected from a discharge
resulting from a storm event that occurs at least
72 hours from the previously measurable storm
event
• In the event that the permittee is unable to
satisfy this condition during the first half of the
sampling period, beginning on the first day of
the second half of the sampling period, the
permittee shall collect samples from a storm
event that occurs at least 48 hours from the
previously measurable event
• The permittee must document the conditioi
under which the storm water samples were
taken, how many manual samples were taken for
the composite sample, and the date of sampling.
This information should be attached to the
sampling results.
If samples cannot be collected, a certification of
why it was not possible to meet the above
protocol may be submitted in lieu of a DMR.
NOTE: Please be advised that on September 24,
1993, EPA Region U issued a revised §401
Certification (Storm Water General Permit
Certification for Storm Water Discharges Associated
with Industrial Activity) for Puerto Rico. This
revision modified "Special Condition Number 13,"
which addresses monitoring requirements, but did not
change any other conditions of the Certification. This
modification has been incorporated into the General
Permit and is reflected in the above summary.
However, please be advised that permittees that were
covered under roe storm water general permit prior to
this date were required to comply with the permit

4J EPA REGION
Whole Effluent Toxidtv ("WE'D Teat Procedures:
Pennioees required to monitor for WET must
follow the Region Vm test procedures as follows:
The permittee must conduct an acute 48-hour static
replacement toxitity test using Ceriodaphnia dubia
and an acute 96-hour static replacement toxicity test
using Pimephales promelas (flathead minnow). The
static replacement toxicity tests must be conducted
in general accordance with "Methods for Measuring
the Acute Toxicity of Effluents to Freshwater
Marine Organisms" EPA/6(Xy4-90-027 (Revised
September, 1991) and me "Region VID EPA
NPDES Acute Test Conditions - Static Renewal
Whole Effluent Toxicity Test" Tests must be
conducted semiannually on a grab sample of the
discharge at 100% strength (no dilution).
After four sets of tests of two species, the permittee
may request mat subsequent testing be limited to
the more sensitive of the two species, based on
results of the previous tests. The permit issuing
authority may approve or deny the request based on
results or other information without an additional
public notice.
Results of all toxicity tests must be reported in a
format consistent with the latest revision of "Region
Vin Guidance for Acute Whole Effluent
Reporting," and Include all chemical and physical
data as specified
NOTE; These WET test procedures specific to
Region Vm were left out of the general permit
language published in the 9/9/92 Federal Register
(57 FR 41236). A correction to Region VIll's final
NPDES general permit for storm water discharges
associated with industrial activity will be published
in a future Federal Register.
