Cleaning Areas. or Deicing Areas Located atAir Transportation Facilities 1. Discharges Covered Under This Section The conditions in this section apply to airports. airport terminals,
aidine carriers. and establishments engaged in servicing. repairing, or maintaining aircraft and ground vehicles. eqUipment cleaning and maintenance (including vehicle and equipment
rehabilitation mechanical repeirs. painting, fueling. lubrication) or deicing/anti-icing operations which conduct the above described activities (facilities generally classified as SIC
code 45), For the purpose of this fInal permit. the term "deicing" is defmed as the process to remove frost. snow, or ice and 􀀢􀁡􀁮􀁴􀁩􀁾􀀠icing" is the process which prevents the accumulation
of frost. snow, Or ice. Both of these activities are covered under this permit. When an industrial facility. described by the above coverage provisions of this section. has industrial
activities being conducted onsite that meet the description(s) of industrialacllvilles in another section(s), that industrial facility shall comply with any and all applicable monitoring
and and pollution prevention plan reqUirements of the other section(s) in addition to all applicable requirements in this section. The monitoring and pollution prevention plan terms
and conditions of this multi-sector permit are additive for industrial activities being conducted at the same industrial facility (co-located industrial activities). The operator of
the facility shall determine which other monitoring and pollution prevention plan section(s) of this permit (if any) are applicable to the facillty. a. Responsible Parties, Airports
typically operate under a single management organization known as the airport "authority" which in most cases is a public agency, Airline carriers and other fixed base operators (e.g.,
fueling companies and maintenance shops) that have contracts with the airport authority to conduct business on airport property are commonly refen'ed to as "tenants" of the alIport.
Tenants may be of two types-those that are regulated as storm water dischargers associated with industrial activities under 40 CFR 122.26(b)(14) and those that are not. The operator
and the tenants of the airport that conduct industrial activities as described above, or as described anywhere in 40 CFR I 22.26(b)(14) and which have storm water discharges, are required
to apply for coverage under an NPDES storm water permit for the discharges from their areas of operation. Where an airport has multiple operators (alIporl authority and tenants) that
have storm water discharges associated with lndustrial activity, as described above, each operator is required to apply for coverage under an NPDES stOrm water permit. This may be done
as separate operators or may be done as 􀁃􀁏􀁾􀀠permittees, Regardless. each individual party. whether a co-permittee or a separate permittee. must submit a notice of intent (NOI) to
be covered under today's permit. During implementation of the storm water pollution prevention plan. the airport authority should work cooperatively with tenants that are not required
to have a NPDES permit for their storm water discharges. The alIport authority may accomplish this through negotiated agreements. contractual requirements, or other means, Ultimately.
the operator(s)1 owner(s) (the airport authority) of the storm water outfalls from the airport is(are) responsible for compliance with all terms and conditions of this or other NPDES
permits applicable to those outfalls. Storm water pollution prevention plans developed separately for areas of the airport facility occupied by tenants of the airport that are regulated
under 40 CFR 122.ll6(b)(14) as a storm water discharge associated with industrial activity shall be integrated into the storm water pollution prevention plan for the entire airport facility.
The airport authority and tenants of the airport are encouraged to apply as co-permittees under today's permit, and to work in partnerShip in the development and implementation of a
storm water pollution prevention plan. 2. Pollutants Found in Storm Water Discharges in general, the quantitative data submitted submitted thus far has not raised any particular areaS
ofconcern with respect to discharges of pollutants resulting from vehicle maintenance and/or deicing/anti-icing operations conducted at airport facilities. However, EPA believes that
the part 2 sampling data does not providejustification that discharges resulting from deicing/antiicing operations are not a significant source of pollutants, The sampiing requirements
for part 2 of the group application did not specifY that facilities must sample stonn water discharges from areas where deiCing/anti-icing activities occur and/or during times when such
operations were being conducted, As a result. only one facility indicated that the sampling data submitted was collected from areas where deicing activities were being conducted. After
reviewing recent case studies on the effects ofglycol discharges to receiving waters. EPA reports and the results of FAA surveys. EPA believes that additional information on the discharges
of 􀁤􀁥􀁩􀁣􀁩􀁮􀁧􀀯􀁡􀁮􀁴􀁩􀁾􀁩􀁣􀁩􀁮􀁧􀀠chemicals to receiving waters as a result of aircraft and runway deicing/anti-icing operations is warranted and necessary. Both ethylene and
propylene glycols exert high ox:ygen demands when reJeased into receiving waters. As such. this section requires that facilities report both the Biochemical Oxygen Demand (BOD) and Chemical
Oxygen Demand (COD) of discharges sampled at facilities that use at least 100.000 gallons or more of glycol-based deiCing/anti-icing chemicals. The concentration of nitrogen and possibly
ammonia are the concern with respect to deicing/antiicing operations where urea is used. Therefore, this section reqUires that facilities subject to the monitoring requirements in Part
Xi.S,S. of the permit also report the concentration of Total Kje1dahl Nitrogen (TKN) in discharges sampled, The results of the storm water survey conducted by the FAA Gune 1992) showed
that 10 percent ofthe respondents who conduct deicing/antiicing activities used more than 100.000 gallons of glycol-based delcing/antiicing chemicalS during winter seasons, In addition,
those facilities using more than 100.000 gallons of glycol-based deicing/anti-icing chemicals accounted for 11 percent of the total amount of glycol-based deicing/anti-lcing chemicals
reported in the survey. ln a similar survey conducted by the American Association of Airport 
Federal Register . VoL 60, No. 189 /Friday, September 1995 /Notices 50999 Executives. 4 percent of the aiIports conducting deicing/anti-icing activities used more than 100,000 gallons
of ethylene glycol which represented approximately 76 percent of the total amount ofethylene glycol used by all airports surveyed. 3. Special Conditions B. Prohibition ofNon·storm Water
Discharges. In addition to the non·storm water prohibitions described under Part IlI.A.2, today's permit clarifies in Part Xl.S.2.a (prohibition of Non-storm Water Discharges) that non-storm
water discharges, including discharges from aircraft, ground vehicle and equipment washwaters, dry weather discharges from airport deicing/anti-icing operations, and dry weather discharges
resulting from runway maintenance are not authorized under this permit. Dry weather discharges are generated from processes other than those described in the definition ofstorm water.
The definition ofstorm water includes storm water runoff. snow melt runoff. and surface runoff and drainage. There is no limit on the time between the snowfall and snow melt for the
purpose of including a snow melt discharge in the definition of storm water. All other discharges not included in the definition ofstorm water constitute nonstorm water discharges. Operators
of non-storm water discharges must obtain coverage under a separate NPDES wastewater permit if such discharges are a point source discharge to waters ofthe U.S. or are discharged through
a municipal separate storm sewer system. In a related requirement, the permittee is requlred to attach a copy of the NPDES pennit issued for the discharge ofnon-storm water runoff or.
ifan NPDES pennit has not yet been issued, a copy of the pending application to the plan. For facilities that discharge the waters mentioned above to a sanitary sewer system. the operator
of the sanitary sewer system must be notified. A copy of the notification letter must be attached to the plan. Ifan industrial user permit has been issued under a pretreatment program.
a copy ofthe permit must be attached to the plan as does any other permit to which the facility's discharge waters are sul:dect. This will help to prevent confusion and help to ensure
that non-storm water discharges are not inadvertently authorized by this permit. b. Releases ofReportable Quantities ofHazardous Substances and Oil. Todais permit clarifies in Part Xl.S.2.b
(Releases ofReportable Quantltles of Hazardous Substances and Oil) that each individual permittee is required to report spUls equal to or exceeding the RQ levels specified at 40 CFR
110, 117 and 302. Ifthe airport authority is the sole permittee, then the sum total ofall spills at the airport must be assessed against the RQ. Ifthe airport authority is a 􀁣􀁯􀁾􀁰􀁥􀁲􀁭􀁩􀁴􀁴􀁥􀁥�
�with other deicing! anti-icing operators at the airport, such as numerous different airlines, the assessed amount must be the summation ofspiUs by each co· permittee. Ifseparate, distinct
individual permittees exist at the airport. then the amount spiUed by each separate permittee must be the assessed amount for the RQ determination. 4. Storm Water Pollution Prevention
Plan Requirement' B. Contents ofthe Plan. The pollUtion prevention plan reqUirements described below are in addition to those found under Part VI.C. (1) Description ofPotential Pollutant
Sources. In addition to the common pollution prevention plan requirements discussed in Part VI.C.2.a. (Drainage), the site map developed for an entire airport shall identify the location
of each tenant of the facility describe their activities. In addition to the pollution prevenuon requirements discussed in Part VI.C.2. (Description ofPotentlal Pollutant Sources). airport
facilities, including areas operated by tenants of the facility that conduct industrial activities, must address the following specific operations and areas where the operations occur:
Aircraft Delc/ngIAnti-icing-lncludes both deicing to remove frost. snow or ice, and anti-icing which prevents the accumulation of frost, snow or ice. Deicing/anti·icing ofan airplane
is accomplished through the application of a freezing point depressant fluid. commonly ethylene glycol or propylene glycol, to the exterior surlace ofan aircraft. Both ethylene and propylene
glycol have high biochemical oxygen demands (BOD) when discharged to receiving waters. Environmental impacts on surface waters due to glycol discharges includes glycol odors and glycol
contaminated surface water and ground water systems. diminished dissolved oxygen levels and fish kills. The Federal Aviation Adminlstration (FAA) recently conducted a survey which focused
on aircraft and runway 􀁤􀁥􀁩􀁣􀁩􀁮􀁧􀁬􀁡􀁮􀁴􀁩􀁾􀁩􀁣􀁩􀁮􀁧􀀠operations at U.S. airports. Ninety·six airports responded to the survey and results are summarized in a fmal report dated
June 1. 1992. In summary, 65 airports indicated the amounts ofethylene glycol used for aircraft deicing for the winter periods of 1989-90 and 1990-91 and the volumes used by each airport
ranged Significantly, from a few gallons to 520,000 gallons. The average annual volume of ethylene glycol used by all respondents for the winter periods of 1989-90 and 199Q...91 was
approximately 2.16 million gallons. The FAA survey summary reported that the m'llority ofaircraft deicing operations occur on the apron adjacent to the passenger terminal and runoff
generally drains to a nearby storm water inlet. In fact, 31 of the respondents to the FAA survey indicated that 75 percent or more of the spent deicing chemicals were discharged to a
storm sewer system. In general, the remainder ofspent chemical resulting from aircraft deicing operations drained to ditches or open areas. All aspects of aircraft deicing/anti· icing
operations. including quantities used and stored, as well as application, handling and storage procedures are required to be addressed under the conditions of this section. (b) Runway
DeicingIAntI·!cingIncludes both deicing and anti-icing operations conducted on runways. taxiways and ramps. Runway deicing! anti-icing commonly i.nvolves either the application ofchemical
fluids such as ethylene glycol or solid constituents such as pelletized urea. Urea has a high nitrogen content. therefore degradation of urea in a receiving water causes an increase
in nutrient loadings resulting in an accelerated growth of algae and eutrophic conditions. Under certain ambient conditions, the degradation of urea in receiving waters can also result
in ammonia concentrations toxic to aquatic life. The FAA's storm water survey reported that, of the facilities that indicated using urea for runway deicing/anti-icing for the winter
periods of 1989-90 and 1990-91. the amount of urea used during a single winter period ranged from 100 pounds to 1,450,000 pounds (715 tons). With regard to disposal ofspent deicing/anti-icing
chemicals from runways. taxi ways and ramps, 20 airports indicated that they discharged 50 percent or more of runoff from deicing areas directly to a storm sewer system. In response
to questions concerning collection and treatment of spent deicing chemicals from runway deicing/anti-icing activities, on1y five facilities indicated that runofffrom runway deicing/anti-icing
operations was collected and treated. All aspects ofrunway deiclng!antiicing operations. including types of deicing/antHcing chemicals. quantities used and stored. as well as application,
handiing and storage procedures are required to be addressed under the conditions of this section. 
51000 Federal Registel Vol. 60, No. 189 I Friday. September 1995 /Notices (c) Aircraft Servicing-Typically conducted on the apron area adjacent to the passenger tenninal. the servicing
of aircraft could potentially contribute pollutants to storm water. As a result of spills or leaks during the servicing of aircraft. fluids such as engine oil, hydraulic fluid. fuel
and lavatory waste could potentially enter the storm water system and/or be discharged to receiving waters. All spillage other than potable water should be prevented from entering the
storm sewer system. (d) Aircraft. Ground Vehicle and Equipment Maintenance and WashingMaintenance activities included in this section include both minor and major operations conducted
either on the apron adjacent to the passenger terminal, or at dedicated maintenance facilities. Potential pollutant sources from all types of maintenance activities include spills and
leaks ofengine oils. hydraulic fluids. transmission oil. radiator fluids, and chemical solvents used for parIS cleaning. fa addition. the disposal ofwaste parIS. batteries, oil and fuel
flllers. and oily rags also have a potential for contaminating storm water runoff from maintenance areas unless proper management practices and operating procedures are implemented.
The spent wash water from aircraft and ground vehicle washing activities could potentially be contaminated with surface dirt. metals. and fluids (fuel. hydraulic fluid. oil. lavatory
waste). (e) Runway Maintenance-Over time. materials such as tire rubber, oil and grease. paint chips. and jet fuel can build up on the surface of a runway causing a reduction in the
friction ofthe pavement surface. When the friction level ofa runway falls below a specific level. then maintenance must be performed. The Federal Aviation Administration (FAA) recommends
several methods for removing rubber deposits and other contaminants from a runway surface including high pressure water. chemical solvents, high velocity particle impact. and mechanical
grinding. If not properly managed. the materials removed from the runway surface could be discharged into nearby surface waters. Simllarly. if chemical solvents are used in the maintenance
operation. improper management practices could result in discharges of the chemical solvents in the storm water runoff from runway areas to nearby surface waters. (2) Measures and Controls.
In addition to the common pollution prevention plan requirements discussed in Part Vl.C.3. (Measures and Controls), this section specifies that permittees must address particular Best
Management Practices (EMF) for specific areas and operations identified as potential sources of pollutanlS. This section further specifies that a schedule for implementation shall be
provided for each BMF selected. The BMPs specified in this section are not fatended to be the only alternative management practices considered by operators. simply the minimum to be
considered. In most cases. the BMPs specified are common sense approaches that are already in practice at many airport facilities. As such, operators may only need to include the information
in their storm water pollution prevention plan. Specific areas and industrial operations mentioned in this section and the corresponding BMPs for such areas are the following: (a) Aircraft,
Ground Vehicle and Equipment Maintenance Areas (including aircraft service areas)-The plan must describe measures that prevent or minimize the contamination ofstann water runofffrom
all areas used for aircraft. ground vehicle and equipment maintenance and servicing. Management practices such as performing all maintenance activities indoors, maintaining an organized
inventory of materials used. draining all parts of fluids prior to disposal. prohibiting the practice of hosing down the apron or hangar floor. using dry cleanup methods in the event
of spills. and/or collecting the storm water runoff from maintenance and/or serviceareas and providing treatment. or recycling should be considered. (b) Aircraft. Ground Vehicle. and Equipment Cleaning Areas-The plan must describe measures that prevent or minimize
the contamination of the storm water runoff from all areas used for aircraft. ground vehicle, and equipment maintenance. Management practices such as performIng all cleaning operations
indoors. and/or collecting the slorm water runoff from the area and providing treatment or recyCling should be considered. (e) Aircraft. Ground Vehicle. and Equipment Storage Areas-The
storage of aircraft. ground vehicles. and eqUipment awaiting maintenance must be confmed to designated areas (delineated on the site map). The plan must describe measures that prevent
or minimize the contamination ofstorm water runoff from these areas, Management practices such as indoor storage ofaircraft and ground vehicles. the use ofdrip pans for the coliection
of fluid leaks. and perimeter drains. dikes or berms surrounding storage areas should be considered. (d) Material Storage Areas-Storage unilS ofali materials (e.g .. used oils. hydraulic
fluids. spent solvents and waste aircraft fuel) must be maintained in good condition. so as to prevent contamination ofstorm water, and plainly labeled (e.g.. "used oil." "Contaminatedjet·A,"
etc.). The plan must describe measures that prevent Or minimize contamination of the slorm water runoff from storage areas. Management practices such as indoor storage of materials,
centralized storage areas for waste materials, andlor installation of berms and dil<es around storage areas should be considered for implementation. (e) Airport Fuel System and Fueling
Areas-The plan must descrihe measures that prevent or minimize the discharge of fuels to the stnrill sewer resulting from fuel servicing activities or other operations conducted in support
of the airport fuel system. Where the discharge of fuels into the storm sewer cannot be prevented. the plan shall indicate measures that will be employed to prevent or minimize the discharge
of the contaminated runoff into receiving surface waters. Where above ground storage timers are present, pollution prevention plan requirements shall be consistent with requirements
established in 40 CPR 112.7 guidelines for the preparation and implementation of a spill prevention control and countermeasure (SPCC) plan. Where a SPCC plan already exists. the storm
water pollution prevention plan may incorporate requirements into the PPP by reference. (I} Source Reduction-This section specifies that fucilitles which conduct aircraft and/or runway
(including taxiways and ramps) deicing/anti-icing operations shall evaluate present operating procedures to consider alternattve practices which would reduce the overall amount of deicing/anti-icing
chemical used and/or lessen the environmental impact of the pollutant source. With regard to runway deicing operations. operators should begin by evaluating present chemical application
rates to ensure against excessive over application. Devices which meIer the amount ofchemical being applied to runways help to prevent over application. Operators should aOO emphasize
anti-icing operations which would preclude the need to deice; less chemical is reqUired to prevent the formation of ice on a runway than is required to remove ice from a runway_ To further
assist in implementing antiicing procedures, operators should also consider installing runway ice detection systems (RID) otherwise known as "pavement sensors" which monitor runway temperatures.
Pavement sensors provide an indication of when runway

operations, Deicing/antHcing chemicals applied during extremely cold. dry conditions. are often ineffective since they do not adhere to the ice surface and may be scattered, as a result
ofwindy conditions or aircraft movement. In an effort to improve the effiCiency ofthe application. operators should consider pre-wetting the deicing chemical to improve the adhesion
to the iced surface. With regard to substitute deleing/chemicals for runway use, operators should consider using chemicals which have less of an environmental impact on receiving waters.
Potassium acetate. has a lower oxygen demand than glycol, is nontoxic to aquatic habitat or humans. and was approved by the FAA for runway deicing operations in November, 1991 (AC No.
150/5200-30A CHG I). In considering alternative management practices for aircraft deicing! operations. operators should evaluate present application rates to ensure against excessive
over application. In addition, operators may consider pretreating aircraft with hot water or forced air prior to the application of chemical deicer. The goal ofthis management practice
is to reduce the amount ofchemical deicer used during the operation. This management practice alone is not sufficient since discharges of small concentrations of glycol can have significant
effects on receiving waters. It is, however, an effective measure to reduce the amount of glycol needed per operation. (g) Management ofRunoff-A number ofreports including EPA's Guidance
For Issuing NPDIlS Storm Water Permits For Airports, September 28, 1991 and Federal Aviation Administration (FAA) Advisory Circular (AC 150-5320-15) indicate that the most common location
for deicing/anti-icing aircraft at U.S. airports is along the apron areas where mobile deicing vehicles operate from gate to gate. In a recent FAA survey of deicing/anti-icing operations
at U.S. airports Oune 1992). the majority of respondents indicated that spent deicer chemicals from aircraft 􀁤􀁥􀁩􀁣􀁩􀁮􀁧􀀯􀁡􀁮􀁴􀁩􀁾􀀠iCing operations either drain to the storm sewer
system, open areas, or are left to evaporate on the ramp. This section specifies that operators shall provide a narrative description of BMPs to control or manage storm water flUlOfi'
from areas where deicinglantiicing operations occur in an effort to minimize or reduce the amount of pollutants being discharged from the site. For example, when delcing/antiicing operations
are conducted on aircraft during periods of dry weather, operators should ensure that storm water inlets are blocked to prevent the discharge ofdeicing/anti·icing chemicals to the stOrm
sewer system. Mechanical vacuum systems or other similar devices can then be used to collect the spent deiCing chemical from the apron surface for proper disposal to prevent those materials
from later becoming a source ofstorm water contamination. Establishing a centralized deicing station would also provide better control over aircraft deicing/anti-icing operations in
that it enables operators to readily collect spent deicing/anti-icing chemicals. Once spent deicer/anti-lcer chemicals are collected,' operators can then select from various methods
of disposal such as: (1) Disposal to Sanitary Sewage Facility-Because glycols are readily biodegradable, runoff can be treated along with sanitary sewage. The receiving treatment plant
WOUld, however, have to have the capacity to handle the hydraulic load as well as the additional biochemical oxygen demand associated with the deicing/anti-icing chemical Measurements
have shown that the average oxygen demand for glycol is between 400,000 and 600.000 mg 021L even ifdiluted per fluid manufacturers specifications (FAA AC 150-5320-15 CHG I, 1991). To
lessen both the increased hydraulic and pollutant loads due to runofffrom airport deicing/anti-icing operations. retention basins may be located at the airport facility. (Ii) Retention
andDetention PondsConversion of suitable unused airport land into retention or detention basins allows for collection oflarge volumes of glycol waste from pavement surface runoff. The
design capacity for such basins should at least handle surface runoffs for winter months noting the decreased microbial activity during the winter season which is needed for biodegradation,
plus additional capacity for runoff during thawing periods. Continuous aeration would supply required oxygen and allow for faster biodegradation and release ofglycol waste, which may
reduce capacity requirements. Metering the discharge of flow from an ansite basin allows the operator to better control the rate of flow during peak flight hours and to avoid BOD shock
loadings to a sanitary treatment facility or a surface water. (iii) Recycling-Glycol recycling provides operators with a chemical cost savings since recaptured glycol can be sold or
reused for other non-aircraft applications (FAA AC 150-5320-15. February 1991). Studies indicate that collected deicing chemicals which have glycol concentrations ranging from 15 to
25 percent can be cost effectively recycled. The optimal conditions for collecting the highest concentration of glycol in spent deicing fluid is directly from the apron or centralized
deicing station when deicing operations are conducted during dry weather or light precipitation events. 􀁄􀁥􀁩􀁣􀁩􀁮􀁧􀁬􀁡􀁮􀁴􀁩􀁾􀁩􀁣􀁩􀁮􀁧􀀠chemicals discharged to retention basins
which are then allowed to mix with additional surface runoff typically result in glycol concentrations well below the acceptable range for recycling. There are, however, methods of physical
separation presently available which increase the concentration of glycol and allow operators to recover a relatively reusable product. (b) Inspections-In addition to the common pollution
prevention plan requirements discussed in Part VI.C.3.d (Inspections). qualified personnel shall inspect equipment and areas involved in deicing/anti-icing operations on a weekly basis
during periods when deicing/anti-icing operations are being conducted. (I) Pollution Prevention TralningPollution Prevention training programs shall infonn management and personnel responSible
for implementing activities identified in the storm water pollution prevention plan of the components and goals of the plan. Training should address topics such as spilJ response, good
housekeeping. material management practices and deicing/antiicing procedures. The pollution prevention plan shall identify periodic dates for such training. EPA recommends that facilities
conduct training annually at a minimum. However. more frequent training may be necessary at facilities with high turnover of employees or where employee participation is essential to
the storm water pollution prevention plan. (3) Comprehensive Site Compliance Evaluation. The storm water pollution prevention plan must describe the scope and content of comprehensive
site evaluation that qualified personnel will conduct to: (I) Confirm the accuracy of the description of potential pollution sources contained in the plan, (2) determine the effectiveness
of the plan, and (3) assess compliance with the terms and conditions of the permit. Comprehensive site compliance evaluations must be conducted at least annually. The individual or individuals
who will conduct the evaluations must be identified in the plan and should be members of the pollution prevention team. Evaluation reports must be 
51002 Federal Registel Vol. 60, No. 189 /Friday, September . 1995 /Notices retained for a period ofat least 3 years following the date ofevaluation. Based on the results of each evaluation,
the description of potential pollution sources, and measures and controls. the plan must be revised as appropriate within 2 weeks after each inspection. Changes in the measures and controls
must be implemented on the site in a timely manner. and no later than 12 weeks after completion ofthe inspection. 5. Numeric Effluent Limitation There are no additional numerical limitations
beyond those in Part V.B. of this permit. 6. Monitoring and Reporting Requirements In general, the quantitative data submitted with part 2 of the group application was inadequate to
clearly identify particular areas of concern with respect to discharges of pollutants resulting from vehicle maintenance andJ or deicing/anti-icing operations conducted at airport facilities.
EPA believes that the part 2 sampling data does not provide justification that discharges resulting from deic!ng/antiicing operations are not a significant source ofpoilutants. The sampling
requirements for part 2 of the group application did not specify that facilities must sample storm water discharges from areas where deicing/anti-icing activities occur andlor during
times when such operations were being conducted. As a result. only one facility iodicated that the sampling data submitted was collected from areas where deicing/anti-icing activities
were being conducted. After reviewing recent case studies on the effects ofglycol discharges to receiving waters, EPA reports. and the results of FAA surveys. EPA believes that additional
information on the impacts of discharges ofdeicing/anti-icing chemicals to receiving waters resulting from aircraft and runway deiclng/antiicing operations is warranted and necessary.
Both ethylene and propylene glycols exert high oxygen demands when released into receiving waters. As such, this section requires that facilities report both the Biochemical Oxygen Demand
(BOD) and Chemical Oxygen Demand (COD) ofdiSCharges sampled at facilities that use at least 100,000 gallons or more of glycol-based deicing/anti-icing chemicals. The concentration of
nitrogen and possibly ammonia are the concern with respect to deicing/antiicing operations where urea is used. Therefore, this section requires that facilities subject to the monitoring
requirements in Part XI.S.S. ofthe pennit also report the concentration of Total Kjeldahl Nitrogen (TKNj in discharges sampled. The results of the stonn water survey conducted by FAA
Gune 1992) showed that 10 percent of the respondents who conduct deicing activities used more than 100,000 gallons ofglycol· based deicing chemicals during winter seasonS, In addition,
those facilities using more than 100,000 gallons of glycol·based delciog chemicals accounted for 71 percent of the total amount of glycol-based deiced chemicals reported by all respondents
in the survey. In a similar sUlVey conducted by the American Association ofAirport Executives, 4 percent of the airports conducting deicing activities used more than 100,000 gallons
of ethylene glycol which represented approximately 76 percent of the total amount of ethylene glycol used by all airports surveyed. a. Annual Loading Estimates. All facilities that use
more than 100.000 gallons ofglycol-based deicing/antiicing chemicals and/or 100 tons or more ofurea on an average annual basis shall prepare estimates ofannual pollutant loadings resulting
from discharges of spent delcing/antl-lciog chemicals from the facility. The loading estimates shall reflect the amounts of deic!ng/antl-Iciog chemicals discharged to separate storm
sewer systems or surlace waters, prior to and after Implementation of the facility's storm water pollution preventlon plan. The purpose of these estimates is to calculate the net reduction
in deicinglanti-icing chemical loadings to receiving streams. Such estimates shalllJe reviewed and certified by an environmental profeSSional (engineer, scientist, etc.) with experience
in stonn water pollution prevention. The environmental professional need not be certified or registered. however. experience with development ofstorm water pollution prevention plans
and with airport operatiOns is critical to prepare accurate estimates. By means of the certification. the environmental professional. having examined the facility's delcing/anti-ic!ng
procedures and proposed control measures described io the storm water pollution prevention plan, shall attest that the loading estimates have been accurately prepared. b. Analytical
Monitoring ReqUirements. EPA believes that airports may reduce the level of pollutants in storm water runoff from their sites through the development and proper implementation of the
storm water pollution prevention plan reqUirements discussed 1n tOday's permit. In order to provide a tool for evaluating the effectiveness of the pollution prevention plan and to characterize
the discharge for potential environmental impacts. the permit reqUires airport facilities that use 100,000 gallons or more ofglycol-based deicing/anti.icing chemlc.als and/or 100 tons
or more of urea on an average annual basis to collect and analyze samples oftheir storm water discharges from areas where deicing/anU·icing activities occur for the pollutants listed
in Table S-l. Airport facilities which use less than 100,000 gallons ofglycolbased deicing/anti-icing chemicals and/or less than 100 tons of urea on an average annual basis are not required
to monitor discharges resultlng from deicing/anti-icing activities. In determining ifan airport is subject to the monitoring requirements. airport authorities must determine the "average
annual usage rate" ofdeicing/anti-icing chemicals at their particular facility. The "average annual usage rate" is determined by averagiog the total amounts ofdelcing/anti-iciog chemicals
used .t the facility for the three previous calendar years. The total amount of deicing/anti-icing chemicals used at an airport facility is the cumulative amount used by the airport
authority and each tenant of the airport facility. EPA recognizes that glycol-based deicing/􀁡􀁮􀁴􀁩􀁾􀁩􀁣􀁩􀁮􀁧􀀠chemicals are often diluted with water prior to deicing aircraft:. In
some cases, deicing/anti-icing chemicals may constitute only 50 percent of the applied volume ofliquid to aircraft. Therefore, in determining the fiuid amounts ofdeicing/anti-icing chemicals
used at a facility. operatorS should use the 􀁰􀁲􀁥􀁾􀁤􀁩􀁬􀁵􀁴􀁩􀁯􀁮􀀠volume. At a minimum, storm water discharges from airport facilities that use 100,000 gallons or more ofglycolbased
deicing/anti-icing chemicals and/or 100 tons or more of urea on an average basis must be monitored four times during the second ye.r of pennit coverage when deicing/anti-icing activities
are occurring and from outfalls that receive stonn water runoff from those areas. At the end of the second year of permit coverage, a facility must calculate the average concentration
for all grab samples analyzed for each parameter listed in Table S-1 on an outfall-by-outfall basis. Ifmore than four different events are sampled during a monitorlng period, then the
average concentration for each parameter shall be determined usiog all grab samples analyzed.

fourth year of the permit will reassess the effectiveness of the adjusted pollution prevention plan. EPA realizes that if a facility is inactive and unstaffed it may be difficult to
collect storm water discharge samples when a qualifying event occurs. Today's final permit has been revised so that inactive, unstaffed facilities can exercise a waiver of the requirement
to conduct quarterly chemical sampling. c. Alternative Certiflcation. The alternative certification provision discussed in other industry sectors described in Part VIII of this fact
sheet are not applicable to discharges resulting from deicing/anti-icing operations. As structured, today's permit only reqUires monitoring from airports that use more than 100.000 gallons
ofglycol-based deicing/anti· icing chemicals and/or 100 tons of urea. In addition. airports that use less than the stated thresholds of deicing/antiicing chemicals are not required to
submit an alternative certification. d, Report.ing Requirements. Permittees are required to submit all monitoring results obtained during the second and fourth year of permit coverage
no later than the 31st day of March following the monitoring period. For each outfall, one signed Discharge Monitoring Report form must be submitted to the Direclor per storm event sampled.
For facilities conducting monitoring beyond the minimum requirements an additional Discharge Monitoring Report Form must be filed for each analysis. e, SampJe Type. A minimum ofone grab
and one flow-weighted composite sample shall be taken from each outfull that collects runofffrom areas where deicing/anti-icing activities occur. The required 72-hour storm event interval
is waived where the preceding measurable storm event did not result in a measurable discharge from the facility. The required 72-hour storm event interval may also be waived where the
permittee documents that less than a 72· hour interval is representative for local storm events during the season when sampling is being conducted, The grab sample is intended to provide
information on the maximum expected concentrations of BOD5. COD. and ammonia as a result of deicing/antiicing chemicals discharged during the precipitation event. The composite sample
is intended to provide a measure of the BOD5. COD. ammonia loadings for the entire precipitation event as a result of the discharge ofdeicing/antiicing chemicals. It will also provide
sitespecific information necessary for calculating the estimates of the annual pollutant loadings also required by this permit. The recommended methodology for performing grab and composite
sampling is described at 40 CFR 122.21 (g) (7), The permittee has the option to submit site..specific deicingl anti-icing discharge monitoring protocol and methodology, better suited
to the particular facility. to the Director for approval. £. Representative Discharge. When a facility has two or more outfalls that. based on a consideration ofindustrial activity,
significant materials. and management practices and activities within the area drained by the outfall, the permittee reasonably believes discharge substantially identical effluents.
the permittee may test the effluent of one ofsuch outfalls and report that the quantitative data also applies to the substantially identical outfall(s) provided that the permittee includes
in the storm water pollution prevention plan a description of the location of the outfalls and explains in detail why the outfalls are expected to discharge substantially identical effluent,
in addition. for each outfall that the permittee believes is representative, an estimate of the size of the drainage area (In square feet) and an estimate of the runoff coefficient of

51004 Federal Registel VoL 60, No. 189 I Friday, September , 1995 I Notices drainage area [e.g., low (under 40 percent), medium (40 to 65 percent), or high (above 65 percenl)] shall
be provided in the plan. T. Storm Water Discharges Associated With Industrial Activity From Treatment Works L Discharges Covered Under this Section On November 16,1990 (55 FR 47990),
the U.S. Environmental Protection Agency (EPA) promulgated the regulatory definition of .. storm water discharges associated with industrial activity." This definition includes point
source discharges of storm water from eleven categories offacilities. including ". • • (ix) treatment works treating domestic sewage or any other sewage sludge or wastewater treatment
device or system, used in the storage. treatment, recycling, and reclamation of municipal or domestic sewage. including land dedicated to the disposal of sewage sludge th.t are located
within the confines of the facility, with a design flow of 1.0 M.G.D. or more or required to have an approved pretreatment program under 40 CFR part 403." This section establishes special
conditions for storm water discharges associated with industrIal activity from treatment works treating domestic sewage with a design flow of 1.0 M.G.D. or more, or for treatment works
that are required to have an approved pretreatment program under 40 CFR Part 403. or for those having land dedicated to the disposal ofsewage sludge within the confines of the fucility.
Please note that storm water discharges from farm 1ands. dome.1Iitic gardens, or lands used for sludge management where sludge is beneficially reused and which are not physically located
in the confines of the facility, or areas that are in compHance with Section 405 of the Clean Water Act (CWA), are not currently regulated under the Federal stOrm water regulations.
When an industrial facility, described by the above coverage provisions of this section, has industrial activities being conducted onsite that meet the description{s) of industrial activities
in another section(s), that industrial facility shall comply with any and all applicable monitoring and pollution prevention plan requirements of the other section(s) in addition to
all applicable requirements in this section. The monitoring and pollution prevention plan tenns and conditions of this muiti-sector permit are additive for industria1 activities being
conducted at the same industrial facility (co-located industrial activities). The operator of the fucility shall determine which other monitoring and po11ution prevention plan section(s)
of this permit (if any) are applicable to the faCility. 2. industry Profile Wastewater treatment plants remove organiC and inorganic contaminants from domestic sewage and sludge. This
section provides a description of the treatment processes for reducing pollutants in domestic sewage. The operations are basically the same at all treatment plants and may be categorized
by three general processes: primary treatment, secondary treatment, and tertiary treatment. Primary Treatment-The objective of primary treatment is the removal of settleable and suspended
organic pollutants. This typically involves at least one of the following operations: screening, grit removal. and sedimentation. Chemical processes, such as disinfection. may also occur
during primary treatment operations, Secondary Treatment-The objective ofsecondary treatment is further removal ofsettleable solids and soluble organic matter. The operations employed
during secondary treatment include biological oxidation via suspended growth or fIxed film processes, such as activated sludge, rotating biological contractors or trickling filters.
Tertiary Treatment-Theobjectives of tertiary treatment include further treatment ofwastewater. such as removal ofsuspended solids by filtration; removal of nutrients, such as phosphorus and nitrogen, typically
through chemical additions and biological processes, or by selective ion exchange; and further removal of pollutants through activated carbon treatment. Prior to discharge into a a receiving
water body, treated wastewater is disinfected using chlorination followed by dechlorination. Sludge produced during primary and secondary treatment is commonly combined. thickened, stablllzed,
and then mechanically dewatered. Sludge is aerobically or anaerobically stab!lized by adjusting the pH with lime. This is followed by dewatering process w here a polymer is added to
condition the sludge for dewatering. Sludge is often stored onsite in piles exposed to weather, until final disposal (e.g .. surface disposal, or incineration). When sludge is to be
land applied, sludge drying beds or composting piles may be exposed to precipitation. In cases where sludge is incinerated onsite of the treatment plant, ash piles or impoundments may
be exposed to precipitation. 3. Pollutants Found In Storm Water Discharges From Treatment Works The impact of industrial activities at treatment works on storm water discharges will
vary. Factors at a site which influence the water quality include geographic location, hydrogeology, the industrial activilies exposed to storm water discharges, the fac!lity's size,
the types of pollution prevention measures/best management practices in place, and the type. duration. and intensity ofstorm events. Taken together or separately, these factors determine
how polluted the storm water discharges will be at a given facility. For example, caustic soda may be significant source of pollutants at some faCilities, while incinerator ash may be
the primary pollutant source at others. Additionally, pollutant sources other than storm water, such as illicit connections, spills, and other improperly dumped materials, may increase
the pollutant loading discharged into Waters ofthe United States. Table T-llists industrial activities that commonly occur at treatment works, common pollutant sources at these facilities.
and pollutants that are associated with these sources. Table T1 identifies parameters as potential pollutants of concern associated with facilities covered by this section. TABLE T-1.-DESCRIPTION

Parts I. and II. describe eligibility requirements and the process for obtaining permit coverage. Parts III.-X. contain "basic" permit reqUirements. facUltIes 140 CPR Part 443 Subpart
A {established July Z4. 1975n NSPS apply only to dl'\charges from those facilities or Jnsraliatlons that were constructed After the promulgation ofNSPS. For example, storm water discharges
from areas where the production ofasphalt paving and roonng emulslotlS occurs are subject to NSPS only ifthe asphalt emulsion facllJry was COIl'Structed after' July 24.1975. Part XL
provides additional reqUirements for particular sectors of industrial activity. For example. primary metal facilities add Part XLF.• to the "universal" Parts I.-X. reqUirements. Some
facilities may have "co«located" activities that are described in more than one sector and need to comply with applicable conditions of each sector. For example, a chemical manufacturing
facility could have a land application site and be subject to Part XI.C.-Chemical and Allied products Manufacturing sector {primary activity}, with runofffrom the land application site
(co-located activity) also subject to conditions in the Part XI.L.-Landillls and Land Application Sites sector. Part XII of the permit contains conditions (e.g., effiuent limitations

that generated the sampled runoff; the duration between the storm event samples and the end of the previous measurable (greater than 0.1 inch rainfall) storm event; and an estimate of
the total volume (in gallons) of the discharge samples. I. Sample Type, For discharges containing coal pile runoff from holding ponds or other impoundments with a retention period greater
than 24 hours 􀀨􀁾􀀮􀁳􀁴􀁩􀁲􀁮􀁡􀁴􀁥􀁤􀀠by dividing the volume of the detention pond by the estimated volume of water discharged during the 24 hours previous to the time that the sample
is COllected), a minimum of one grab sample may be taken. For all other discharges containing coal pile runoff, data shall be reported for a grab sample, All such samples shall be collected
from the discharge resulting from a storm event that is greater than 0.1 inches in magnitude and that occurs at least 72 hours from the previously measurable (greater than 0,1 inch rainfall)
storm event. The required 􀀷􀀲􀁾􀁨􀁯􀁵􀁲􀀠storm event interval is waived where the preceding measurable storm event did not result in a measurable discharge from the facility. The required
72-hour storm event interval may also be waived where the permittee documents that les.s than a 72hour interval is representative for local storm events during the season when sampling
is being conducted. The grab sample shall be taken during the first 30 minutes of the discharge. If the collection of. grab sample during the first 30 minutes is impracticable. a grab
sample can be taken during the first hour ofthe discharge, and the discharger shall submit with the monitoring report a description ofwhy a grab sample during the first 30 minutes was
impracticable, 2, Sampling Waiver. When a discharger is unable to collect samples ofcoal pile runoff due to adverse climatic conditions. the discharger shall collect a substitute sample
from a separate qualifYing event in the next period and submit this data along with the data for the routine sample in that period. Adverse weather conditions that may prohibit the collection
collection of samples include weather conditions that create dangerous conditions for personnel (such as local flooding, high winds, hurricane, tornadoes, electrical storms, etc.) or
otherwise make the collection of a sample impracticable (drought, extended frozen conditions, etc,). 3. Representative Discharge. When a facility has two or more outfalls containing
coal pile runoff that, based on a consideration ofthe other industrial activity. and Significant materials. and upon management practices and activities within the area drained by the
outfall, and the permittee reasonably believes substantially Identical effluents are discharged, the permittee may test the effiuent ofone of such outfalls and report that the quantitative
data also applies to the substantially identical outfalls provided that the permittee includes in the storm water pollution prevention plan a description ofthe location of the out.falls
and explains in detail why the outfalls are expected to discharge substantiaUy identical effluents. In addition, for each outfall that the permittee believes is representative, an estimate
ofthe size ofthe drainage area (in square feet) and an estimate ofthe runoff coefficient of the drainage area (e,g., low (under 40 percent), medium (40 to 65 percent) or high (above
65 percent)) shall be provided in the plan. Pennittees required to submit monitoring infonnation under Part VJII. of this permit shall include the description of the location of the
outfalls, explanation ofwhy outfalls are expected to discharge substantially identical effluents, and estimate of the size of the drainage area and fWloff coefficient with the Discharge
Monitoring Report. This representative discharge provision 15 not applicable to storm water discharges from coal piles regulated under the national effiuent limitations guidelines, 4.
Alternative Certification. Facilities with storm water discharges containing coal pile runoff may not submit alternative certification in lieu of the required monitoring data. 5. When

ofstorm water. The definition ofstonn water includes stonn water runoff. snow melt runoff. and surface runoff and drainage. All other discharges constitute non-storm water discharges.
Operators of non-stonn water discharges must obtain coverage under a separate National Pollutant Discharge Elimination System (NPDIlS) permit ifdischarged to waters of the United States
or through a municipal 􀁳􀁥􀁾􀁲􀁡􀁴􀁥􀀠storm sewer system. (b) Releases ofReportable Quantities ofHa7.ardous Substances and Oil. Each individual permittee is required to report spills
equal to or exceeding the reportable quantity levels specified at 40 CFR 110. 117. and 302 as described at Part VI.B.2. Ifan airport authority is the sale permittee. then the sum total
ofall spills at the airport must be assessed against the RQ. If the airport authority is a co-permittee with other deicing! anti-icing operators at the airport, such as nwnerous different
airlines, the assessed amount must be the summation ofspills by each co· permittee. If separate. distinct individual permittees exist at the airport. then the amount spilled by each
separate permittee must be the assessed amount for the RQ determination. 3. Storm Water Pollution Prevention Plan Requirements Storm water pollution prevention plans developed for areas

fInal permit. the "average annual" usage rate ofdeicingiantHcing chemicals is determined by averaging the cumulative amount of deicing/anti-icing chemicals used by all operators at the
airport facility in the 3 previous calendar years. (I) Monitoring Periods. Airports where more than 100,000 gallons of glycol-based deicing/anti-icing chemicals and/or 100 tOnS Or more
of mea are used on an average annual basis shall monitor outfalls from the facility that col1ect runoff from areas where deicingiantHcing activities occur four times peryear during the
months of December. January. and February when deicing/antiwicing activities are occurring, in in the years specified in paragraph b. (above). (2) Sample Type. A minimum of one grab
sample and one flow-weighted composite sample shall be taken from each outfall that collects runoff from areas where deicing/anti-icing activities occur. All such samples shall be collected
from a discharge resulting from a precipitation event that is greater than D. I inches In magnitude and that occurs at least 72 hours from the previously measurable (greater than D.
I inch rainfall) precipitation event. The required72-hour storm event interval is waived where the preceding measurable storm event did not result in a measurable discharge from the facility. The required 72-hour storm event interval
may also be waived where the permittee documents that less than a 72hour interval is representative for local storm events during the season when sampling is being conducted_ The grab
sample should be taken when pollutant concentrations in the storm water/melt water discharges from deicing/anti-icing operations are expected to to be at a maximum. The recommended methodology
for performing grab and flow-weighted composite sampling is described at 40 CFR 122.21(g)(7). The permittee has the option to submit sitespecific deiCing/anti-icing discharge monitoring
protocol and methodology, better suited to the particular facility, to the Director for approval. (3) Sampling Waiver. (a) Adverse CondWons-Adverse weather conditions that may prohibit
the collection ofsamples include weather conditions that create dangerous conditions for personnel (such as high winds, blizzard conditions, ice storms, etc,) or otherwise make the collection
ofa sample impracticable (extended frozen conditions, etc.). (b) Low Concentration Waiver-When the average concentration for a parameter calculated from all grab samples callected during
the monitoring period [insert date I year after permit !ssuance] lasting through [insert date 2 years after permit issuance] is less than the corresponding value for that parameter listed
in Table S-I under the column Monitoring Cut-off ConcentraUon. a facility may waive monitoring and reporting reqUirements in the monitoring period beginning [insert date 3 years after
permit issuance] lasting through [insert date 4 years after permit issuance]. The facility must submit to the Director. in lieu of the monitoring data, a certification that there has
not been a Significant change in industrial activity or the pollution prevention measures in area of the f.clIity which drains to the outfall for which sampling was waived. (c) When
a discharger is unable to conduct quarterly chemical stonn water sampling at an inactive and unstaffed site. the operator oflhe facility may exercise a waiver of the monitoring reqUirements
as long as the facility remains inactive and unstaffed. The facility must submit to the Director, in lieu of monitoring data. a certification statement on the DMR stating that the site
is inactive and unstaffed so that collecting a sample during a qUalil'ying event is not possible. (4) Representative Dlscharge_ When a facility has two or more outfalls that, based on
a consideration ofindustrial activity. significant materials, and management practices and activities within the area drained by the outfall, the permittee reasonably believes discharge
substantially identical effluents, the permittee may test the effluent of one ofsuch outfalls and report that the quantitative data also applies to the substantially identical outfall(s)
provided that the permittee inc1ude..<; in the storm water pollution prevention plan a description of the location of the outfalls and explains in detail why the outfalls are expected
to disCharge substantially identical effluents. In addition. for each outfall that the permittee believes is representative, an estimate of the size of the drainage area (in square feet)
and an estimate of the runoffcoefficient of the drainage area [e.g .. low (under 40 percent). medium (40 to 65 percent), Or high (above 65 percent)] shall be provided in the plan. The
permittee shall include the description of the the location ofthe outfalls, explanation of why outfalls are expected to discharge substantially identical effluents, and estimate of the
size of the drainage area and runoff coefficient with the Discharge Monitoring Report. (5) Alternative Certiflcation. The Alternative Certification provision discussed in other sections
of Part Xl is not applicable to discharges included under Part XI.S. (Storm Water Discharges Associated with Industrial Activity from Vehicle Maintenance Areas. Equipment Cleaning Areas,

A BRIEF GUIDE TO REQUIREMENTS FOR DEVELOPING AND IMPLEMENTING POLLUTION PREVENTION PLANS FOR INDUSTRIAL ACTIVITIES Storm water runoff is part ofthe natural hydrologic cycle. However,
human activities, particularly urbanization, can alter natural drainage patterns and add pollutants to the rainwater and snowmelt that run offthe earth's surface and enter our Nation's
rivers, lakes, streams, and coastal waters. In fact, recent studies have shown that storm water runoff is a major source ofthe pollutants that are damaging our sport and commerciallisheries,
restricting swimming, and affecting the navigability of many of our Nation's waters. The States and many municipalities have been taking the initiative to manage storm water discharges
more effectively. Recognizing the importance ofthis problem, Congress also directed the U.S. Environmental Protection Agency (EPA) to develop a Federal program under the Clean Water
Act to regulate certain high-priority storm water sources. The issuance of storm water discharge discharge permits under the National Pollutant Discharge Elimination System (NPDES) is
a major part of the Agency's efforts to restore and maintain the Nation's water quality. Under the NPDES General Permit for Storm Water Discharges Associated wilh Industrial Activity,
EPA requires the development and implementation of a pollution prevention plan -designed to reduce pollution at the source, before it can cause environmental problems that cost the public
and private sectors in terms of lost resources and expensive environmental restoration activities. OVERVIEW OF POLLUTION PREVENTION PLAN REQUIREMENTS As shown on the chart on the following
page, pollution prevention plan requirements have been organized to provide you with a step-by-step process for ensuring that pollutants are not making their way into the storm water
discharges from your site. Toward this end, you will be selecting and implementing Best Management Practices (BMPs). BMPs include schedules of activities, prohibitions of practices,
maintenance procedures, and other management practices to prevent or reduce the pollution in runofffrom your site. The five major phases ofthe developing a pollution prevention plan
are (1) planning and organization; (2) assessment; (3) BMP selection and plan design; (4) implementation; and (5) evaluation and site inspection. All permit holders must meet a number
of general requirements. In addition, permittees who are subject to reporting requirements under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA), (also
known as Title 3 ofthe Superfund Amendment and Reauthorization Act [SARAD, will have to meet special requirements under EPA's general permit These requirements are listed in boxes throughout
this guide, and then elaborated upon in the final section. This guide provides background information on pollution prevention planning requirements for permittees under the general permit.
To walk you through the requirements, the guide is organized according to the phases of the pollution prevention planning process. A set of worksheets and a model plan althe end of the
document are provided to further clarify requirements. A detailed manual on how to develop and implement your pollution prevention plan is available at a modest cost from the National
Technical Information Service. The manual, titled Storm Water Management for Industrial Activities: Developing Pollution Prevention Plans and Best Management Practices, provides much
more specific information than this brief guide. Instructions for ordering the detailed manual and a listing of other references that you may find useful can be found at the end of this
guide. RevieW Draft Page 1

PLANNING AND 􀁮􀁬􀀺􀀱􀁲􀀮􀁬􀀱􀁾􀀢􀀢􀀠, 'PI-Il1C:I'" Before you start putting your Storm Water Pollution Prevention Plan together, there are two steps that will facilitate the development
of your plan, These steps are designed to help you organize your staff and make preliminary decisions: (A) decide who will be responsible for developing and implementing your Storm Water
Pollution Prevention Plan, and (B) look et other existing environmentel facility plans for consistency and overlap. (A) Forming Your Pollution Prevention Team As part of developing and
implementing your pollution plan, you should (1) designate a specific individual or team who will develop, implement, maintain, and revise your pollution prevention plan, and (2) identify
these individuals and describe each person's responsibilities at the site, Since facilities differ in size and capacity, the number of team members will also vary. Designating one person
may be appropriate as long as that individual is qualified to design and implement the plan. The plan should identify those people on site who are most familiar with the facility and
its operations; these people, in turn, should provide structure and direction to the storm water management program, In all cases, someone in a senior management position must have overall
responsibility for the plan. The pollution prevention team is responsible for the following: • Implementing all general permit and pollution prevention plan requirements Defining and
agreeing upon an appropriate set of goals for the facility's storm water management program Being aware of any changes that are made in plant operations to determine whether any changes
must be made to the Storm Water Pollution Prevention Plan Maintaining a clear line of communication with plant management to ensure a cooperative partnership. Worksheet 111 (located
at the end ofthis guide) is an example of an appropriate form on which to list the team members. To complete this worksheet, list the pollution prevention team members by name, facility
position (title), and pihone number; include a brief description of each member's specific responsibilities. This list can be directly incorporated into the Storm Water Pollution Prevention
Plan, but it should also be displayed or posted within the facility so that other plant employees are aware of who is responsible for storm water management (B) Building on Existing
Environmental Management Plans The pollution prevention team also must evaluate existing environmental management plans for consistency and determine which, if any, provisions can be
incorporated into the Storm Water Pollution Prevention Plan, Other related plans may include the Preparedness, Prevention and Contingency Plan (40 CFR Parts 264 and 265), the Spill Control
and Countermeasures requirements (40 CFR Part 112), the National Pollutant Discharge Elimination System Toxic Organic Management Plan (40 CFR Parts 413, 433, and 469), and the Occupational
Safety and Health Administration (OSHA) Emergency Action Plan (29 CFR Part 1910). Although you should build on relevant portions of other environmental plans as appropriate, it is important
to note that your Storm Water Pollution Prevention Plan must be a comprehensive, stand-alone document ReviewDraft Page 3 
ADDITIONAL REQUIREMENTS FOR FACIUTIES SUBJECT TO REPORTING UNDER EPCRA. SECTION 313. FOR WATER PRIORITY CHEMICAlS-EPCRA contains additional reporting requirements for designated hazardous
waste management facilities. EPA's Baseline General Permit contains the following specific requirements for such facilities: The team must designate a person who will be accountable
for spill prevention at the facility and identity this person in the plan. • The designated person is responsible for setting up necessary spill emergency procedures and reporting requirements
to isolate, contain, and clean up spills and emergency releases of Section 313 water priority chemica Is. ReviewDraft Page 4 
ASSESSMENT PHASE After identifying who is responsible for developing and implementing your plan and organizing your planning process, you should proceed to this next step-a pollutant
source assessment. This is where you take a Jook at your facility and determine what materials or practices are (or may be) a source of contaminants to the storm water running off your
site. To complete this phase, you will (A) create a map of the facility site to locate pollutant sources and determine storm water management opportunHies, (8) conduct a material inventory,
(e) evaluate past spills and leaks, (D) identify non-storm water discharges and illicH connections, (E) collect or evaluate storm water quality data, and (F) summarize the findings ofthis
assessment. To select the most appropriate and effective control measures, consider that potential pollutant sources include areas where materials are handled or stored, outdoor processing
areas, loading and unloading areas, and onsite waste management and disposal areas, (A) A) Developing a Site Map A site map is a complete illustration of site features. At a minimum,
the site map must include information on the following: • Discharge points ("oulfalls") Drainage patterns Identification of the types of pollutants likely to be discharged for each drainage
area Direction of flow Surface water bodies, including any proximate stream, river, lake, or other water body receiving storm water discharges from the sHe Structural control measures
(physically constructed features used to control storm water flows) Locations of significant materials exposed to storm water Locations of industrial activities (such as fueling stations,
loading and unloading areas, vehicle or eqUipment maintenance areas, waste disposal areas, storage areas), Worksheet #2 (located at the end of this guide) provides guidance on completing
your site map. (8) Materials Inventory Each facility must inventory the types of matenals that are handled, stored, or processed onsHe. "Significant materials" are of particular concern
and are defined as follows: Significant Materials: Raw materials; fuels; materials such as solvents, detergents, and plastic pellets; finished materials such as metallic products; raw
materials used in food processing or production; hazardous substances designated under section 101(14) of CERCLA; any chemical the facility is required to report pursuant to EPCRA, Section
313; fertilizers; pesticides; and waste products such as ashes, slag, and sludge that have the potential to be released with storm water discharges [40 CFR 122.26(b)(12)}. Review Draft
PageS 
To complete the materials inventory, the facility must do two specific tasks: List materials that have been exposed to storm water in the past 3 years (focus on areas where materials
are stored, processed, transported, or transferred). Provide a narrative description of methods and location of storage and disposal areas, materials management practices, treatment
practices, and any structurallnonstructural control measures. -structural practices are fixed equipment such as berms, detention ponds, or grassed swales. -Nonstructural practices may
include regularly scheduled actions such as sweeping or inspections. Worksheet #3 (located at the end of this guide) will assist you in conducting a material inventory for your Storm
Water Pollution Prevention Plan. If any of the significant materials on your site have been exposed to storm water in the 3 years prior to the effective date of your permit, complete
Worksheet #3A and include it in your plan. (C) Identifying Past Spills and Leaks Provide a list ofsignificant spills and leaks of toxic or hazardous that have occurred in the past 3
years. "Significant spills" includes releases in exceas of reportable quantities defined as follows: Reportable Quantity (RQ) Discharge: An RQ release occurs when a quantity of a hazardous
substance or oil is spilled or released within a 24-hour period of time and exceeds the RQ level assigned to thet substance under C£RCLA or the Clean Water Ad. These levels or quantities
are defined in terms ofgallons or pounds. Regulations listing these quantities are contained at 40 CFR 302.4, 40 CFR 117.21 and 40 CFR 110.10. Permittees are encouraged to list spills
and leaks of nonhazardous materials as well as spills of hazardous materials. Worksheet #4 (located at the end of this guide) can help you organize this list of leaks and spills. The
areas on your site where significant leaks or spills have occurred are areas on which you should focus very closely when selecting BMPs. (0) Non·Storm Water Discharges Tocertify that your facility has been tested or evaluated for non-storm water discharges, you must: • Identify potential non-storm water discharges Describe the method used and results
of any test and/or evaluation for such discharges Indicate the location ofthe onsile drainage points that were checked during the tsst or evaluation Provide the date of the test or evaluation.
(If you cannot test or evaluate potential non-storm water discharges, notice must still be made by certification.) Examples of non-storm water discharges include any water used directly
in the manufacturing process (process water), air conditioner condensate, noncontact cooling water, vehicle wash water, or sanitary wastes. To check for non-storm water discharges, you
can use one of the following three common dry weather tests: visual inspection; plant schematic review; and/or dye testing. Review Draft Page 6 
Worksheet #5 (located at the end of this guide) will assist you in conducting a non-s\orm water discharge assessment and certification for outfalls at your site. If you are unable to
test and/or provide certification for the presence of non-s\orm water discharges, please refer to Worksheet #6. (E) Existing Monitoring Data Where existing storm water sampling data
are available, the facility must (1) provide a summary of any existing storm water sampling data and (2) describe the sample collection procedures used. (F) Site Evaluation Summary This
step is critical, as it will become the foundation for the rest ofthe Storm Water Pollution Prevention Plan. Facilities must fulfill the following requirements: Provide a narrative description
of activities with a high potential to contaminate storm water at your site, including those associated with materials loading and unloading, outdoor storage, outdoor manufacturing or
processing, onsile waste disposal, and significant dust or particulate generating activities Describe any pollutants of concem that may be associated with such activities. Once you have
completed the above steps in your pollutant source assessment, you should have enough information to determine which areas, activities, or materials may contribute pollutants to storm
water runoff from your site. With this information, you can select the most appropriate BMPs to prevent or control pollutants from these areas. Review Draft Page 7 
BMP/SELECTION AND PI AN L PI-IAC:.,. Once you have identified and assessed potential and existing sources of storm water contamination at your faCility. the next step is to select the
proper Best Management Practices (BMPs) that will address these pollutant sources. To satisfy the requirements ofthis phase, you must provide a narrative description ofthe BMPs you have
selected for your site. At a minimum, your plan must incorporate the following eight "baseline" BMPs: (A) good housekeeping, (B) preventive maintenance. (C) visual inspections, (0) spill
prevention and response, (E) sediment and erosion prevention, (F) traditional storm water management practices, (G) other BMPs as appropriate. (H) employee training, and (I) recordkeeping
and reporting. A number of these BMPs are discussed below. (A) Good Housekeeping Good housekeeping practices are designed to maintain a clean and orderly work environment Often the most
effective first step towards preventing pollution in storm water from industrial sites involves merely using good common sense to improve the facility's basic housekeeping methods. The
following are some simple procedures that a facility can consider incorporating into an effective good housekeeping program: Improve operation and maintenance of industrial machinery
and processes. Implement careful material storage practices. Maintain up-to-date material inventory. -Identify all chemical substances present in the workplace. -Label all containers
showing name and type of substance. stock number, etc. Schedule routine cleanup operations. Maintain well-organized work areas. Train employees about good housekeeping practices. (8)
Preventive Maintenance Each permittee must develop a preventive maintenance program that involves inspectiOns and maintenance of storm water management devices and routine inspections
of facility operations to detect faulty equipment Equipment (such as tanks, containers, and drums) should be checked regularly for signs ofdeterioration. Review Draft PageB 
EPCRA. SECTION 313, FACIUTY PREVENTIIIE MAINTENANCE INSPECTION REQUIREMENTS-Ali areas of the facility must be inspected for the following at appropriate intervals as specified in the
plan: Leaks or conditions that would lead to discharges of Section 313 water priority chemicals Conditions that could lead to direct contact of storm water with raw materials, intermediate
materials, waste materials or products • Piping, pumps, storage tanks and bins, pressure vessels, process and material handling equipment, and material bulk storage areas for leaks,
wind blowing, corrosion, support or foundation failure, or other deterioration or noncontainment. (C) Visual Inspections Regular visual inspections are your means to ensure that all
of the elements of the plan are in place and working properly 10 prevent pollution of storm water runoff from your facility. Consider the following when conducting visual inspections:
Designate qualified, trained plant personnel to regulany inspect the facility's equipment and areas, track results of inspections, make necessary changes, and maintain records of all
inspections • Ensure that inspection records note when inspections were done, who conducted the inspection, what areas were inspected, what problems were found, and what steps were taken
10 correct any problems. These records should be kept wilh the plan. EPA's general permit requires that records be kept until at least one year after coverage under the permil expires.
(0) Spill Prevention and Response Areas where spills are likely to occur and their drainage points must be clearly identified in the storm water pollution prevention plan. You should
ensure that employees are aware of response procedures, including material handling and storage requirements. Also ensure thatthere is access to appropriate spill cleanup equipment SPILL
PREVENTION PLAN CONSIDERA110NS: Install leak detection devices. Adopt good housekeeping practices. Perform regular visual inspections to identifY areas for potential leaks or spills.
• ReCYCle, reduce, and reuse process materials 10 minimize waste onsite. SPill RESPONSE PLAN CONSIDERA 11OOS: Identify a spill response team to implement the spill response plan. Identify
safety measures. ReviewDraft Page 9 
• Include procedures for notifying appropriate authorities (police, lire, hospital, Publicly Owned Treatment Works [P01Wj, etc.) in the event of a spill. Describe spill containment,
diversion, isolation, and cleanup practices. EPCRA, SECTION 313, FACILITY SPILL PREVENTION AND RESPONSE REQUIREMENTs-When a leak or spill of a Section 313 water priority chemical has
occurred, the contaminated soil, material, or debris must be removed promptly and disposed of in accordance with Federal, State, and local requirements and as described in the Storm
Water Pollution Prevention Plan. These facilities are also required to designate a person responsible for spill prevention, response, and reporting procedures. (E) Sediment and Erosion
Control The facility's pollution prevention plan must identify activities that present a potential for significant soil erosion and measures taken to control such erosion. More information
on sediment and erosion control BMPs can be found in the reference section of this guide. (F) Management of Runoff Permittees must describe existing storm water controls found at the
facilily and any additional measures that can be implemented to improve the prevention and control of polluted storm water. Examples include: vegetative swales, reuse of collected storm
water, infiltration trenches, and detention ponds. Review Draft Page 10 
IMPLEMENTATION PHASE At this point, you have designed your Storm Water Pollution Prevention Plan and the plan has been approved by facility management. Under the implementation phase,
you must (A) implement the selected storm water 8MPs, and (8) train all employees to carry out the goals ofthe plan. (A) Implementing Appropriate Controls In implementing the plan, a
facility will: Develop a schedule for implementation. For example, your schedule might include a deadline for putting improved housekeeping measures into practice. Some controls may
be immediately put into action; others will be phased in. Assign specific individuals with responsibility for implementing aspects ofthe plan andlor monitoring implementation. Ensure
that management approves of your implementation schedule and strategy, and schedule regular times for reporting progress to management. (8) Employee Training Permittees must develop
an employee training program that covers such topics as spill prevention and response, good housekeeping, and material management practices. The goals of a training program are to teach
personnel, at all levels of responsibility, the components and goals of the storm water pollution prevention plan and to create overall sensitivity to storm water pollution prevention
concerns. The plan must include a schedule for training programs. EPCRA. SECTION 313. FACILITY REQUIREMENTs-There are additional training requirements for employees and contractor personnel
who work in areas where EPCRA, Section 313, water priority chemicals are used or stored. These individuals must be trained in the following areas, at least once per year: Preventive
measures, including spill prevention and response and preventive maintenance Pollution control laws and regUlations The facility's Storm Water Pollution Prevention Plan Features and
operations ofthe facility that are designed to minimize discharges of Section 313 water priority chemicals, particularly spill prevention procedures. Review Draft Page 11 
EVALUATION PHASE Now that your Storm Water Pollution Prevention Plan has been put to action, you must keep it up-to-date by regularly evaluating the information you collected in the
Assessment Phase and the controls you selected in the Plan Design Phase. Specifically, you must (A) conduct site evaluations, (B) keep records of all inspections and reports, and (C)
revise the plan as needed. (A) Annual Site Compliance Evaluation Qualified personnel must conduct site compliance evaluations at appropriate intervals, but at least once a year (at least
once in 3 years for inactive mining sites). As part of your compliance evaluations, you are required to carry out the following: Inspect storm water drainage areas for evidence of pollutants
entering the drainage system. Evaluate the effectiveness of BMPs (for example, is your site cleaner? Are your employees more familiar with good housekeeping measures and spill prevention
and response practices?) Observe structural measures, sediment controls, and other storm water BMPs to ensure proper operation. Revise the plan as needed within 2 weeks of inspection,
and implement any necessary changes within 12 weeks of the inspection. • Prepare a report summarizing inspection results and followup actions, identifying the date of inspection and
personnel who conducted the inspection. Sign the report and keep it with the plan. (8) Recordkeeping and Internal Reporting Your facility must record and maintain records of spills,
leaks, inspections, and maintenance activities for at least one year after the permit expires. For spills and leaks, records should include information such as the date and time of the
incident, weather conditions, cause, and resuHing environmental problems. (C) Plan Revisions Major changes in a facility's design. construction, operation, or maintenance will necessitate
changes in that facility's Storm Water Pollution Prevention Plan. Review Draft Page 12 
GENERAL ... This section provides guidance on some of the administrative requirements related to organizing and developing your Storm Water Pollution Prevention Plan. The guidance covers
(A) deadlines for plan development and implementation, (8) required Signatures, (e) requirements for plan location and access, and (D) Director-required plan modifications. (A) Deadlines
for Plan Development and Implementation Schedule for Plan Development and Implementation PartlV.A. Deadline for Plan Deadline for Plan Type of Facility Development Implementation , Facilities

may grant a written extension for plan preparation and compliance for new dischargers (after October 1, 1992) upon showing of good cause. (B) Required Signatures As with the Notice of
Intent (NOI), your plan must be signed by an "authorized representative," who is a person at or near the top ofyour facility's management chain (the president, vice president, or a production
manager) who has been delegated the authority to sign and certify this type of document EPCRA, Section 313, Facility Plan Certification Requirements-The plan must be reviewed and certified
by a Registered Professional Engineer and recertified every 3 years or after the plan is significantly changed. This certification that the plan was prepared in accordance with good
engineering practices does not relieve the facility owner or operator of responsibilitY to prepare and implement the plan, however. Review Draft Page 13 
(C) Plan Location and Public Access Although all plans are required to be maintained onsite, some NPDES storm water permits may require that facilities submit copies of their Storm Water
Pollution Prevention Plans to the Director for review. Examine your permit carefully to determine what submittal requirements apply to your facility. Plans and all required records must
also be kept at least one year a/terthe permit expires. (D) Director-Required Plan Modifications Upon reviewing your plan, the permitting authority may find that it does not meet one
or more ofthe minimum standards established by the pollution prevention plan requirements. In this case, the permitting authority will notify you of the changes that you must make to
improve the plan. Review Draft Page 14 
SPECIAL REQUIREMENTS In addition to the minimum "baseline" BMPs discussed in previous sections, facilities may be subject to additional "special" requirements. Not all facilities will
have to include these special requirements in their Storm Water Pollution Prevention Plan. Be sure to check your permit closely for these conditions. In particular, EPA's general pemnit
includes special requirements for (A) facilities that discharge stomn water through municipal separate stomn sewer systems, (8) facilities subject to EPCRA, Section 313, reporting requirements,
and (C) facilities with salt storage piles. (A) Special Requirements for Discharges Through Municipal Separate Storm Sewer Systems Industrial facilities that discharge stomn water through
a large or medium municipal separate storm sewer system (serving a population of 100,000 or more) must comply with any applicable conditions established by the municipality's stomn water
management program. These facilities will be notified by the municipality. Examples Examples of conditions could include additional monitoring requirements and/or additional source control
requirements. (8) Special Requirements for EPCRA, Section 313, Reporting Facilities In addition to the other special requirements identified in this guide, the following specific control
requirements must be practiced in areas where Section 313 water priority chemicals are stored, handled, processed, or transferred: Provide containment, drainage control, and/or diversionary
structures (prevent or minimize runon by installing curbing, culverting, guttars, sewers, or other controls, and/or prevent or minimize exposure by covering storage piles). • Prevent
discharges from liquid storage areas (store liquid materials in compatible storage containers and/or provide secondary containment designed to hold the volume of the largest storage
tank plus precipitation). • Prevent discharges from material storage areas (install drainage and/or other control measures). • Prevent discharges from loading/unloading areas ((use drip
pans and/or implement a strong spill contingency and integrity testing plan). • Prevent discharges from handlinglprocessingltransferring areas (use covers, guards, overhangs, door skirts
and/or conduct visual inspections or leak tests for overhead piping). • Prevent discharges from all the above areas (use manually activated valves with drainage controls in all areas,
and/or equip the plant with a drainage system to return spilled material to the facility). • Introduce facility security programs to prevent spills (use fencing, lighting, traffic control,
and/or secure equipment and buildings). (C) SpeCial Requirements for Salt Storage Piles Salt storage piles used for deicing or other commercial purposes must be enclosed or covered to
prevent exposure to storm water (except when salt is being added or removed from the pile). Please note that piles do not need to be enclosed or covered where storm water is not discharged
to waters of the United Sates. Compliance with this requirement must be met as expeditiously as practicable, but no later than 3 years after the NOI is submitted. Review Draft Page 15
