SECTION 12
WASTEWATER MANAGEMENT
U.S. TEAM Guide, March 2001
A. Applicability
This section includes regulations, responsibilities, and compliance requirements associated with wastewater
discharge. Wastewater discharge can include any of the following:
1. sanitary or industrial wastewater discharge directly to a receiving stream
2. sanitary or industrial wastewater discharge to a publicly owned treatment works (POTW)
3. sanitary or industrial wastewater discharge to a Federally owned treatment works (FOTW) or other nonAgency treatment facility
4. stormwater runoff from operational areas to a receiving stream or water body
5. industrial wastewater or stormwater drained to an industrial waste reservoir.
Most facilities have wastewater discharge of one kind or another, and therefore this section will be applicable.
Assessors are required to review state and local regulations and, if applicable, the appropriate Agency Supplement,
to perform a comprehensive assessment.
B. Federal Legislation
• The Federal Water Pollution Control Act. This act, commonly known as the Clean Water Act (CWA), as
amended 4 February 1987, 33 U.S. Code (USC) 1251-1387, Public Law (PL) 100-4, governs the control of water
pollution in the nation. The objective of the act is to restore and maintain the chemical, physical, and biological
integrity of the nation’s waters. Federal agencies are required to comply with all Federal, state, interstate, and
local water pollution control requirements both substantively and procedurally (33 USC 1323(a)).
• The Federal Facility Compliance Act (FFCA). This act, dated 6 October 1992, amends the Solid Waste Disposal
Act (SWDA) and addresses requirements for Federally owned treatment works (FOTW) under 42 USC 6939(e)
(PL 102-386). The FFCA establishes a conditional domestic sewage exclusion for industrial discharges to an
FOTW. This allows an FOTW to accept hazardous wastes, provided that certain conditions are met and the
wastes are not acutely hazardous.
• Executive Order (EO) 12088, Federal Compliance with Pollution Standards. This EO, dated 13 October 1978,
requires Federally owned and operated treatment works to comply with applicable Federal, state, and local water
pollution control standards. It makes the head of each executive agency responsible for seeing to it that the
agencies, facilities, programs, and activities the agency funds meet applicable Federal, state, and local
environmental requirements or to correct situations that are not in compliance with such requirements. In
addition, the EO requires that each agency ensure that sufficient funds for environmental compliance are included
in the agency budget.
C. State/Local Regulations
For information on regulations in specific states, see the State Supplements to TEAM Guide.
States normally have wastewater discharge legislation and regulations which require permitting similar to the
National Pollutant Discharge Elimination System (NPDES) program. The state is often delegated authority to
administer the NPDES permits for discharges within their state. These permits are often joint permits issued
pursuant to both Federal and state legislation. In some cases, the state will not administer the NPDES program and
12-1
Wastewater
will issue a state permit even though an NPDES permit has been issued by the U.S. Environmental Protection
Agency (USEPA). The states and the USEPA normally cooperate in the permit issuance process to insure that the
two permits are consistent, but there may be differences in monitoring requirements and the number of pollutants
limited. These requirements normally do not conflict, but may require additional sampling and dual reporting.
States also have more stringent requirements for wastewater treatment plant operations. Many states have
wastewater treatment plant (WWTP) operator licensing and certification programs which require that an operator
pass an exam and have a required amount of experience.
Local entities (counties, cities) may also have enforceable wastewater discharge limitations that regulate discharges
to a POTW. Local limitations often include pH, temperature, and concentrations of various organic and inorganic
compounds. Major industrial operations which discharge to an offsite POTW will be subjected to pretreatment
permits issued by the POTW, state, or USEPA as appropriate.
D. Key Compliance Requirements
• NPDES Permits - Point source discharges are required to have a Federal NPDES permit if located in states
without a USEPA approved NPDES permit program. Dischargers of stormwater associated with an industrial
activity are required to apply for an individual permit, apply for a permit through a group application, or seek
coverage under a promulgated stormwater general permit. Stormwater permits may also be a construction issue.
Sampling requirements stipulated by NPDES permits must be met (40 CFR 122.1(b)(3) and 122.26(c)).
• Pretreatment Requirements - Any pollutant that would cause pass through or interference must not be discharged
into a treatment works, either POTW or FOTW. Pollutants shall be introduced into a treatment works that create
a fire or explosion hazard, cause corrosive structural damage, have a pH below 5.0, or are solid or viscous enough
to cause obstructions. Treatment works must be notified immediately of any discharge, including any slug
loadings, that could cause problems to the treatment works (40 CFR 403.5 and 403.12(f)).
• Operation and Maintenance of an FOTW/POTW - Treatment plant supervisors are required to maintain operating
logs and records that are posted daily and are neat and legible. Treatment plants are required to be operated in
accordance with all design parameters (40 CFR 403.12(f)).
• Effluent Limitations for Steam Electric Power Generating Sources - Steam electric power generating sources must
meet point source effluent limitations. Of special concern is the discharge of free available chlorine and total
residual chlorine. Additionally there must be no discharge of polychlorinated biphenyls (PCB). There are
additional standards depending on if the source is a new or an existing source (40 CFR 423).
• Effluent Limits for Electroplating Point Sources - Existing electroplating operations that introduce pollutants into
a POTW resulting from the electroplating of common metals are subject to pretreatment standards which vary
depending upon the level of discharge and the nature of the metals used (40 CFR 413).
• Effluent Limitation for Metal Finishing Point Sources - Shops performing electroplating, electroless plating,
anodizing, coating, chemical etching and milling, and printed circuit board manufacturing are subject to certain
best available technology (BAT) point source effluent limitations, which include the self-monitoring of cyanide.
Existing metal finishing point sources introducing pollutants into POTWs are subject to certain pretreatment
standards. New metal finishing point sources introducing pollutants into POTWs are subject to certain
performance and pretreatment standards (40 CFR 433).
• Effluent Limitations for Transportation Cleaning Equipment – This regulations sets standards for discharges
resulting from cleaning the interior of tanks used to transport chemical, petroleum or food grade cargos. These
requirements do not apply to facilities that clean only the exteriors of transportation equipment. Operations that
may be subject to these requirements typically are reported under a wide variety of Standard Industrial
Classification (SIC) codes. Several of the most common SIC codes include: SIC 7699, SIC 4741, or SIC 4491
(1987 SIC Manual). These requirements are not applicable to the following discharges:
12-2
Wastewater
1. wastewaters associated with tank cleanings operated in conjunction with other industrial, commercial, or
POTW operations, provided that the cleaning is limited to tanks that previously contained raw materials,
by-products, or finished products that are associated with the facility's onsite processes
2. wastewaters resulting from cleaning the interiors of drums, intermediate bulk containers, or closed-top
hoppers
3. wastewater from a facility that discharges less than 100,000 gal/yr of transportation equipment cleaning
process wastewater (40 CFR 442).
• Discharge Limits for Hospitals - Hospital are required to limit the quantity and quality of their discharges. The
following are restricted: BOD5, TSS, and pH (40 CFR 460).
• Discharge Limits for Photo Labs - Photo labs that process more than 150 m2 per day of film must limit their
discharges for silver, CN, and pH (40 CFR 459).
• Land Application of Sludge - 40 CFR 503 details the pollutant concentrations, cumulative loading rates, and other
restrictions pertinent to the land application of sludge that is generated during the treatment of domestic sludge in
a treatment works. See Section 1 titled Air Emissions Management for requirements on the incineration of sewage
sludge.
• Surface Disposal of Sewage Sludge - The operation, management, monitoring, and closure requirements for units
used for the surface disposal of sewage sludge are outlined in 40 CFR 503.20 through 503.28.
• Discharges from Armed Forces Vessels. Numerous types of discharges incidental to the normal operation of
Armed Forces vessels must have a marine pollution control device (MPCD) to mitigate adverse impacts on the
marine environment. This requirement applies to the owners and operators of Armed Forces vessels, except
where the Secretary of Defense finds that compliance with this part is not in the interest of the national security of
the United States. This requirement does not apply to vessels while they are under construction, vessels in
drydock, amphibious vehicles, or vessels under the jurisdiction of the Department of Transportation other than
those of the Coast Guard. These requirements are not applicable beyond the contiguous zone. (40 CFR 1700.1
through 1700.5).

disposal are subject to regulations promulgated pursuant to section 405(d) of the CWA and is required to obtain a
permit under Sec. 122.1(b)(2) (40 CFR 122.2) [Added July 2000].
• Small Municipal Separate Storm Sewer System (MS4) - all separate storm sewers that are (40 CFR 122.26(b)(16))
[Added January 2000]:
1. owned or operated by the United States, a state, city, town, borough, county, parish, district, association,
or other public body (created by or pursuant to state law) having jurisdiction over disposal of sewage,
industrial wastes, storm water, or other wastes, including special districts under State law such as a sewer
district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized
Indian tribal organization, or a designated and approved management agency under section 208 of the
CWA that discharges to waters of the United States
2. not defined as “large” or “medium” municipal separate storm sewer systems
3. this term includes systems similar to separate storm sewer systems in municipalities, such as systems at
military bases, large hospital or prison complexes, and highways and other thoroughfares. The term does
not include separate storm sewers in very discrete areas, such as individual buildings.
A small MS4 is regulated under the NPDES storm water program when it is (40 CFR 122.32(a)):
1. operated by Federal, state, tribal, and local governments, including state departments of transportation;
and:
2. located in an urbanized area as determined by the latest Decennial Census by the Bureau of the Census.
(If the small MS4 is not located entirely within an urbanized area, only the portion that is within the
urbanized area is regulated); or
3. designated by the NPDES permitting authority or is based upon a petition.
A small MS4 may receive a waiver of permit coverage if it serves a population of less than 1,000 within the
urbanized area and the following criteria are met (40 CFR 122.32(d)):
1. the system is not contributing substantially to the pollutant loadings of a physically interconnected MS4
that is regulated by the NPDES stormwater program; and
2. for discharges of any pollutants that have been identified as a cause of impairment of any water body to
which the system discharges, storm water controls are not needed based on wasteload allocations that are
part of a USEPA-approved or established TMDL that addresses the pollutants of concern.
A small MS4 may receive a waiver of permit coverage if it serves a population of less than 10,000 and the
following criteria are met (40 CFR 122.32(e)):
1. the permitting authority has evaluated all waters of the United States, including small streams, tributaries,
lakes, and ponds, that receive a discharge from the MS4;
2. for all such waters, the permitting authority has determined that stormwater controls are not needed based
on wasteload allocations that are part of a USEPA approved or established TMDL that addresses the
pollutants of concern or, if a TMDL has not been developed or approved, an equivalent analysis that
determines sources and allocations for the pollutants of concern (NOTE: The pollutants of concern
include BOD, sediment or a parameter that addresses sediment (such as total suspended solids, turbidity
or siltation), pathogens, oil and grease, and any pollutant that has been identified as a cause of impairment
of any water body that will receive a discharge from the MS4.); and
3. the permitting authority has determined that future discharges from the MS4 do not have the potential to
result in exceedances of water quality standards, including impairment of designated uses, or other
significant water quality impacts, including habitat and biological impacts.

[Added January 2000].
• Stormwater Discharge Associated With an Industrial Activity -the discharge from any conveyance that is used for
collecting and conveying stormwater and that is directly related to manufacturing, processing or raw materials
storage areas at an industrial plant. The term does not include discharges from facilities or activities excluded
from the NPDES program under this 40 CFR 122. For the categories of industries identified in 40 CFR 122.26,
the term includes, but is not limited to, stormwater discharges from industrial plant yards; immediate access roads
and rail lines used or traveled by carriers of raw materials, manufactured products, waste material, or by-products
used or created by the facility; material handling sites; refuse sites; sites used for the application or disposal of

equipment; sites used for residual treatment, storage, or disposal; shipping and receiving areas; manufacturing
buildings; storage areas (including tank farms) for raw materials, and intermediate and final products; and areas
where industrial activity has taken place in the past and significant materials remain and are exposed to
stormwater. For the purposes of this definition, material handling activities include storage, loading and
unloading, transportation, or conveyance of any raw material, intermediate product, final product, by-product or
waste product. The term excludes areas located on plant lands separate from the plant's industrial activities, such
as office buildings and accompanying parking lots as long as the drainage from the excluded areas is not mixed
with stormwater drained from the above described areas. Industrial facilities (including industrial facilities that are
federally, state, or municipally owned or operated that meet the description of the facilities listed in the definition
of Industrial Activities) include those facilities designated under the provisions of 40 CFR 122.26(a)(1)(v) (40
CFR 122.26(b)(14)) [Revised January 2000].
• Stormwater Discharge Associated With Small Construction Activity - the discharge of stormwater from (40 CFR
122.26(b)(15)) [Added January 2000]:

to or greater than 1 acre and less than 5 acres. Small construction activity also includes the disturbance of
less than 1 acre of total land area that is part of a larger common plan of development or sale if the larger
common plan will ultimately disturb equal to or greater than 1 and less than 5 acres. Small construction
activity does not include routine maintenance that is performed to maintain the original line and grade,
hydraulic capacity, or original purpose of the facility. The Director may waive the otherwise applicable
requirements in a general permit for a stormwater discharge from construction activities that disturb less
than 5 acres where:
a. the value of the rainfall erosivity factor (“R” in the Revised Universal Soil Loss Equation) is less than
five during the period of construction activity. The rainfall erosivity factor is determined in
accordance with Chapter 2 of Agriculture Handbook Number 703, Predicting Soil Erosion by Water:
A Guide to Conservation Planning With the Revised Universal Soil Loss Equation (RUSLE), pages
21-64, dated January 1997. The Director of the Federal Register approves this incorporation by
reference in accordance with 5 U.S.C 552(a) and 1 CFR part 51. Copies may be obtained from
EPA's Water Resource Center, Mail Code RC4100, 401 M St. S.W., Washington, DC 20460. A
copy is also available for inspection at the U.S. EPA Water Docket , 401 M Street S.W.,
Washington, DC 20460, or the Office of the Federal Register, 800 N. Capitol Street N.W. Suite 700,
Washington, DC. An operator must certify to the Director that the construction activity will take
place during a period when the value of the rainfall erosivity factor is less than five; or
b. stormwater controls are not needed based on a total maximum daily load (TMDL) approved or
established by USEPA that addresses the pollutants of concern or, for non-impaired waters that do
not require TMDLs, an equivalent analysis that determines allocations for small construction sites
for the pollutants of concern or that determines that such allocations are not needed to protect water
quality based on consideration of existing in-stream concentrations, expected growth in pollutant
contributions from all sources, and a margin of safety. The pollutants of concern include sediment or
a parameter that addresses sediment (such as total suspended solids, turbidity or siltation) and any
other pollutant that has been identified as a cause of impairment of any water body that will receive a
12-19
Wastewater
discharge from the construction activity. The operator must certify to the Director that the
construction activity will take place, and storm water discharges will occur, within the drainage area
addressed by the TMDL or equivalent analysis.
2. any other construction activity designated by the Director or, in states with approved NPDES programs,
either the Director or the USEPA Regional Administrator, based on the potential for contribution to a
violation of a water quality standard or for significant contribution of pollutants to waters of the United
States.
• Strong Chelating Agents - all compounds which, by virtue of their chemical structure and amount present, form
soluble metal complexes which are not removed by subsequent metals control techniques such as pH adjustment
followed by clarification or filtration (40 CFR 413.02).

commodities or cargos in bulk in cargo spaces (or tanks) through rivers and inland waterways, and may
occasionally carry commodities or cargos through oceans and seas when in transit from one inland waterway to
another. The commodities or cargos transported are in direct contact with the tank interior. There are no maximum
or minimum vessel or tank volumes (40 CFR 442.2) [Added October 2000].
• Tank Truck - a motor-driven vehicle with a completely enclosed storage vessel used to transport liquid, solid or
gaseous materials over roads and highways. The storage vessel or tank may be detachable, as with tank trailers, or
permanently attached. The commodities or cargos transported come in direct contact with the tank interior. A tank
truck may have one or more storage compartments. There are no maximum or minimum vessel or tank volumes.
Tank trucks are also commonly referred to as cargo tanks or tankers (40 CFR 442.2) [Added October 2000].
• TTO - total toxic organics (40 CFR 413.02).
• Total Hydrocarbons - the organic compounds in the exit gas from a sewage sludge incinerator stack measured

• Transportation Equipment Cleaning (TEC) Process Wastewater - all wastewaters associated with cleaning the
interiors of tanks including: tank trucks; rail tank cars; intermodal tank containers; tank barges; and ocean/sea
tankers used to transport commodities or cargos that come into direct contact with the interior of the tank or
container. At those facilities that clean tank interiors, TEC process wastewater also includes wastewater generated
from washing vehicle exteriors, equipment and floor washings, TEC-contaminated stormwater, wastewater
prerinse cleaning solutions, chemical cleaning solutions, and final rinse solutions. TEC process wastewater is
defined to include only wastewater generated from a regulated TEC subcategory. Therefore, TEC process
wastewater does not include wastewater generated from cleaning hopper cars, or from food grade facilities
discharging to a POTW. Wastewater generated from cleaning tank interiors for purposes of shipping products
(i.e., cleaned for purposes other than maintenance and repair) is considered TEC process wastewater. Wastewater
generated from cleaning tank interiors for the purposes of maintenance and repair on the tank is not considered
TEC process wastewater. Facilities that clean tank interiors solely for the purposes of repair and maintenance are
not regulated under 40 CFR 442 (40 CFR 442.2) [Added October 2000].
• Treat or Treatment of Sewage Sludge - the preparation of sewage sludge for final use or disposal. This includes,

in Sewage Sludge”, EPA-625/R-92/013, 1992, U.S. Environmental Protection Agency, Cincinnati, Ohio
45268).
2. When the 38 percent volatile solids reduction requirement in paragraph 1 cannot be met for an
anaerobically digested sewage sludge, vector attraction reduction can be demonstrated by digesting a
portion of the previously digested sewage sludge anaerobically in the laboratory in a bench-scale unit for
40 additional days at a temperature between 30 and 37 C. When at the end of the 40 days the volatile
solids in the sewage sludge at the beginning of that period are reduced by less than 17 percent, vector
attraction reduction is achieved.
3. When the 38 percent volatile solids reduction requirement in paragraph 1 cannot be met for an aerobically
digested sewage sludge, vector attraction reduction can be demonstrated by digesting a portion of the
previously digested sewage sludge that has a percent solids of 2 percent or less aerobically in the
laboratory in a bench-scale unit for 30 additional days at 20 C. When at the end of the 30 days the
volatile solids in the sewage sludge at the beginning of that period are reduced by less than 15 percent,
vector attraction reduction is achieved.
4. The specific oxygen uptake rate (SOUR) for sewage sludge treated in an aerobic process shall be equal to
or less than 1.5 mg of oxygen per hour per gram of total solids (dry weight basis) at a temperature of 20

C.
5. Sewage sludge shall be treated in an aerobic process for 14 days or longer. During that time, the
temperature of the sewage sludge shall be higher than 40 C and the average temperature of the sewage
sludge shall be higher than 45 C.
6. The pH of sewage sludge shall be raised to 12 or higher by alkali addition and, without the addition of
more alkali, shall remain at 12 or higher for 2 h and then at 11.5 or higher for an additional 22 h.
7. The percent solids of sewage sludge that does not contain unstabilized solids generated in a primary
wastewater treatment process shall be equal to or greater than 75 percent based on the moisture content
and total solids prior to mixing with other materials.
8. The percent solids of sewage sludge that contains unstabilized solids generated in a primary wastewater
treatment process shall be equal to or greater than 90 percent based on the moisture content and total
solids prior to mixing with other materials.
12-21
Wastewater
9. Sewage sludge shall be injected below the surface of the land. No significant amount of the sewage sludge
shall be present on the land surface within 1 h after the sewage sludge is injected. When the sewage
sludge that is injected below the surface of the land is Class A with respect to pathogens, the sewage
sludge shall be injected below the land surface within 8 h after being discharged from the pathogen
treatment process.
10. Sewage sludge applied to the land surface or placed on an active sewage sludge unit shall be incorporated
into the soil within 6 h after application to or placement on the land, unless otherwise specified by the
permitting authority.
11. When sewage sludge that is incorporated into the soil is Class A with respect to pathogens, the sewage
sludge shall be applied to or placed on the land within 8 h after being discharged from the pathogen
treatment process.
12. Sewage sludge placed on an active sewage sludge unit shall be covered with soil or other material at the
end of each operating day.
13. The pH of domestic septage shall be raised to 12 or higher by alkali addition and, without the addition of
more alkali, shall remain at 12 or higher for 30 min.

NPDES PERMITS
WA.10.1.US. Point source
discharges are required to
have either a state NPDES or
a Federal NPDES permit if
located in states without an
USEPA-approved
NPDES
permit program (40 CFR
122.1(b), 122.21(b)(iv) and
122.41(a)) [Revised October
1999, Revised July 2000].
Verify that discharges of pollutants from any point source into waters of the
United States have an NPDES permit.
(NOTE: Look for oil/water separators and washracks that discharge directly to the
environment.)
(NOTE: This permit program also applies to owners or operators of any treatment
works treating domestic sewage, whether or not the treatment works is otherwise
required to obtain an NPDES permit. Exemptions from the NPDES permit
requirements include facilities holding permits issued under the Solid Waste
Disposal Act; Safe Drinking Water Act; Marine Protection, Research, and
Sanctuaries Act; the Clean Air Act; or an USEPA-approved state program
adequate to assure compliance with Section 405 of the CWA (i.e., sludge disposal
requirements, implemented via 40 CFR 503). In addition, where no 40 CFR 503
standard exists for a facility's use or disposal practice, the owner/operator of the
facility is not automatically required to submit a permit application (64 FR 42437).
For example, industrial treatment works that treat domestic sewage along with
process wastes are not currently addressed under 40 CFR 503 and, therefore,
USEPA does not require that they apply for a sewage sludge permit at this time
(64 FR 42437).)
(NOTE: The Director may require permit applications from any treatment works
treating domestic sewage at any time the Director determines a permit is necessary
to protect public health and the environment from any potential adverse effects
that may occur from toxic pollutants in sewage sludge.)
Verify that permit requirements are being met such as:
 monitoring/sampling
 concentrations of discharge constituents
 recordkeeping
 reports.
(NOTE: Excursions from the permit required pH range are permitted subject to the
following limitations:
 the total time during which the pH values are outside the required range of
pH values does not exceed 7 h and 26 min in any calendar month
 no individual excursion from the range of pH values exceeds 60 min.)
(NOTE: The Regional Administrator may designate any person subject to the
standards for sewage sludge use and disposal as a “treatment works treating
domestic sewage”, where the Regional Administrator finds that a permit is

one or more other operators of discharges from the large or medium
municipal storm sewer system that covers all, or a portion of all, discharges
from the municipal separate storm sewer system
 submits a distinct permit application that only covers discharges from the
municipal separate storm sewers for which the operator is responsible.
(NOTE: One permit application may be submitted for all or a portion of all
municipal separate storm sewers within adjacent or interconnected large or
medium municipal separate storm sewer systems. Permits for all or a portion of all
discharges from large or medium municipal separate storm sewer systems that are
issued on a system-wide, jurisdiction-wide, watershed, or other basis may specify
different conditions relating to different discharges covered by the permit,
including different management programs for different drainage areas that
contribute stormwater to the system. Co-permittees need only comply with permit

Conditional Exclusion for “No Exposure” of Industrial Activities and Materials to Stormwater.
(40 CFR 122.26(g))
[Added January 2000]
To qualify for the “no exposure” exclusion, the operator of the discharge must:
1. Provide a storm resistant shelter to protect industrial materials and activities from exposure to rain, snow, snow
melt, and runoff;
2. Complete and sign a certification that there are no discharges of storm water contaminated by exposure to
industrial materials and activities from the entire facility, except as provided below
3. Submit the signed certification to the NPDES permitting authority once every 5 yr;
4. Allow the Director to inspect the facility to determine compliance with the “no exposure” conditions;
5. Allow the Director to make any “no exposure” inspection reports available to the public upon request; and
6. For facilities that discharge through an MS4, upon request, submit a copy of the certification of “no exposure” to
the MS4 operator, as well as allow inspection and public reporting by the MS4 operator.
To qualify for the “no exposure” exclusion, storm resistant shelter is not required for:
1. Drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not
deteriorated and do not leak (“Sealed” means banded or otherwise secured and without operational taps or
valves);
2. Adequately maintained vehicles used in material handling; and
3. Final products, other than products that would be mobilized in storm water discharge (e.g., rock salt).
The “no exposure” certification includes submission of the following information, at a minimum, to aid the NPDES
permitting authority in determining if the facility qualifies for the no exposure exclusion:
1. The legal name, address, and phone number of the discharger;
2. The facility name and address, the county name, and the latitude and longitude where the facility is located;
3. Indication that none of the following materials or activities are, or will be in the foreseeable future, exposed to
precipitation:
a) Using, storing, or cleaning industrial machinery or equipment, and areas where residuals from using,
storing, or cleaning industrial machinery or equipment remain and are exposed to storm water;
b) Materials or residuals on the ground or in storm water inlets from spills/leaks;
c) Materials or products from past industrial activity;
d) Material handling equipment (except adequately maintained vehicles);
e) Materials or products during loading/unloading or transporting activities;
f) Materials or products stored outdoors (except final products intended for outside use, e.g., new cars, where
exposure to storm water does not result in the discharge of pollutants);
g) Materials contained in open, deteriorated, or leaking storage drums, barrels, tanks, and similar containers;
h) Materials or products handled/stored on roads or railways owned or maintained by the discharger;
i) Waste material (except waste in covered, non-leaking containers, e.g., dumpsters);
j) Application or disposal of process wastewater (unless otherwise permitted); and
4. Particulate matter or visible deposits of residuals from roof stacks/vents not otherwise regulated, i.e., under an
air quality control permit, and evident in the storm water outflow; the following certification statement, and be
signed in accordance with the signatory requirements of 40 CFR 122.22: “I certify under penalty of law that I
have read and understand the eligibility requirements for claiming a condition of “no exposure” and obtaining
an exclusion from NPDES stormwater permitting; and that there are no discharges of storm water contaminated
by exposure to industrial activities or materials from the industrial facility identified in this document (except as
allowed under paragraph (g)(2) of this section). I understand that I am obligated to submit a no exposure
certification form once every 5 yr to the NPDES permitting authority and, if requested, to the operator of the
local MS4 into which this facility discharges (where applicable). I understand that I must allow the NPDES
permitting authority, or MS4 operator where the discharge is into the local MS4, to perform inspections to
confirm the condition of no exposure and to make such inspection reports publicly available upon request. I
understand that I must obtain coverage under an NPDES permit prior to any point source discharge of storm
12-131
Wastewater
water from the facility. I certify under penalty of law that this document and all attachments were prepared under
my direction or supervision in accordance with a system designed to assure that qualified personnel properly
gathered and evaluated the information submitted. Based upon my inquiry of the person or persons who manage
the system, or those persons directly involved in gathering the information, the information submitted is to the
best of my knowledge and belief true, accurate and complete. I am aware there are significant penalties for
submitting false information, including the possibility of fine and imprisonment for knowing violations.”
Stormwater discharges from construction activities identified in paragraphs (b)(14)(x) and (b)(15) are not
eligible for this conditional exclusion.
This conditional exclusion from the requirement for an NPDES permit is available on a facility-wide basis only, not
for individual outfalls. If a facility has some discharges of storm water that would otherwise be “no exposure”
discharges, individual permit requirements should be adjusted accordingly.
If circumstances change and industrial materials or activities become exposed to rain, snow, snow melt, and/or
runoff, the conditions for this exclusion no longer apply. In such cases, the discharge becomes subject to
enforcement for un-permitted discharge. Any conditionally exempt discharger who anticipates changes in
circumstances should apply for and obtain permit authorization prior to the change of circumstances.
The NPDES permitting authority retains the authority to require permit authorization (and deny this exclusion) upon
making a determination that the discharge causes, has a reasonable potential to cause, or contributes to an instream
excursion above an applicable water quality standard, including designated uses.

(x) provisions for maintaining appropriate records of heel management procedures, prerinse/pre-steam
management procedures, cleaning agent management procedures, operator training, and proper operation and
maintenance of any pre-treatment system;
For PSNS the Pollutant Management Plan shall include:
(i) Procedures for identifying cargos, the cleaning of which is likely to result in discharges of pollutants that would
be incompatible with treatment at the POTW;
(ii) For cargos identified as being incompatible with treatment at the POTW, the Plan shall provide that heels be
fully drained, segregated from other wastewaters, and handled in an appropriate manner;
(iii) For cargos identified as being incompatible with treatment at the POTW, the Plan shall provide that the tank
be prerinsed or presteamed as appropriate and the wastewater segregated from wastewaters to be discharged to the
POTW and handled in an appropriate manner, where necessary to ensure that they do not cause or contribute to a
discharge that would be incompatible with treatment at the POTW;
(iv) All spent cleaning solutions, including interior caustic washes, interior presolve washes, interior detergent
washes, interior acid washes, and exterior acid brightener washes shall be segregated from other wastewaters and
handled in an appropriate manner, where necessary to ensure that they do not cause or contribute to a discharge that
would be incompatible with treatment at the POTW;
(v) Provisions for appropriate recycling or reuse of cleaning agents;
(vi) Provisions for minimizing the use of toxic cleaning agents (solvents, detergents, or other cleaning or
brightening solutions);
(vii) Provisions for appropriate recycling or reuse of segregated wastewaters (including heels and prerinse/presteam wastes);
(viii) Provisions for off-site treatment or disposal, or effective pre-treatment of segregated wastewaters (including
heels, prerinse/pre-steam wastes, spent cleaning solutions);
(ix) Information on the volumes, content, and chemical characteristics of cleaning agents used in cleaning or
brightening operations; and
