metals and organic chemicals) and otherpollutants such as trash, debris, and oil and

grease, when acility practices allow exposureo industrial materials to stormwater Thisincreased fow and pollutant load can impairwaterbodies, degrade biological habitats, pol-lute drinking water sources, and cause food-ing and hydrologic changes to the receivingwater, such as channel erosion

Industrial acilities typically perorm aportion o their activities in outdoor areasexposed to the elements This may includeactivities such as material storage and han-dling, vehicle ueling and maintenance, ship-

ping and receiving, and salt storage, all owhich can result in pollutants being exposedto precipitation and capable o being carriedo in stormwater runo Also, acilities mayhave perormed industrial activities outdoorsin the past and materials rom those activitiesstill remain exposed to precipitation In addi-tion, accidental spills and leaks, improperwaste disposal, and illicit connections tostorm sewers may also lead to exposure opollutants to stormwater

EPA has identied six types o activities at

industrial acilities that have the potential tobe major sources o pollutants in stormwater:

LoadingandUnloadingOperations

Loading and unloading operations caninclude pumping o liquids or gases romtankers to storage acilities, pneumatictranser o dry chemicals, transer bymechanical conveyor systems, or transero bags, boxes, drums or other contain-ers by orklit or other material handling

equipment Material spills or losses in theseareas can accumulate and be washed awayduring a storm

OutdoorStorage

Outdoor storage activities include stor-age o uels, raw materials, by-products,intermediate products, nal products, and

process residuals Materials may be storedin containers, on platorms or pads, in bins,boxes or silos, or as piles Storage areasthat are exposed to rainall and/or runocan contribute pollutants to stormwaterwhen solid materials wash o or materialsdissolve into solution

OutdoorProcessActivities

Although many manuacturing activitiesare perormed indoors, some activities,such as timber processing, rock crush-ing, and concrete mixing, occur outdoors

Outdoor processing activities can result inliquid spillage and losses o material solids,which makes associated pollutants avail-able or discharge in runo

DustorParticulateGeneratingProcesses

Dust or particulate generating processesinclude industrial activities with stackemissions or process dusts that settle onsuraces Some industries, such as mines,cement manuacturing, and reractories,also generate signicant levels o dust thatcan be mobilized in stormwater runo

IllicitConnectionsandNon-Stormwater

Discharges

Illicit connections o process wastes orother pollutants to stormwater collectionsystems, instead o to sanitary sewers, canbe a signicant source o stormwater pol-lution Non-stormwater discharges includeany discharge rom the acility that is notgenerated by rainall runo (or example,wash water rom industrial processes)With ew exceptions, these non-stormwaterdischarges are prohibited Reer to your

permit or a list o authorized non-storm-water discharges

WasteManagement

Waste management practices includeeverything rom landlls to waste piles totrash containment All industrial acilitiesconduct some type o waste managementat their site, much o it outdoors, whichmust be controlled to prevent pollutantdischarges in stormwater

Where Do I Get a Copy of the IndustrialStormwater General Permit in My State?

To determine who issues the industrialstormwater permit in your State, you can visitEPAs stormwater website at www.epa.gov/npdes/stormwater/authorizationstatus orthe Industrial Stormwater Resource Locator at

www.envcap.org/iswrl

Who Is an Operator?

EPA denes the operator o an industrial acil-ity as:

Theentitythathasoperationalcontroloverindustrial activities, including the ability tomodiy those activities, or

Theentitythathasday-to-dayoperationalcontrol o activities at a acility neces-sary to ensure compliance with the permit(eg, the entity that is authorized to directworkers at a acility to carry out activitiesrequired by the permit) See denition inAppendix A o the 2008 MSGP

In many cases, the owner and operator areone in the same person In a ew instances,there may be more than one operator at a site(with the owner being an operator based onthe denition provided above) Where there isboth an owner (without operational control)and an operator, it is the operators responsi-bility to obtain permit coverage and complywith the permit provisions

2.B What Are the Basic ElementsRequired in a SWPPP?

A SWPPP is a written document that identi-es the industrial activities conducted at thesite, including any structural control prac-tices, which the industrial acility operatorwill implement to prevent pollutants rom

making their way into stormwater runoThe SWPPP also must include descriptions oother relevant inormation, such as the physi-cal eatures o the acility, and procedures orspill prevention, conducting inspections, andtraining o employees The SWPPP is intendedto be a living document, updated as neces-sary, such that when industrial activities orstormwater control practices are modied orreplaced, the SWPPP is similarly revised torefect these changes

The process o developing a SWPPP involves

the ollowing our steps:

Step 1: Formation o a pollution preven-tion team o qualied personnel who willbe responsible or preparing the plan andassisting the plant manager in implement-ing practices to comply with the permit;

Step 2: Assessment o potential stormwaterpollution sources;

Step 3: Selection o appropriate controlmeasures that minimize the discharge opollutants during storm events or each othese sources; and

Step 4: Development o procedures orconducting required inspection/monitoringactivities, as well as regular maintenanceo control measures

This guide will assist you with these oursteps The selection o a pollution preven-tion team is discussed in the next section(Section 2C) Site assessment is addressed inSection 3, the selection o control measures isdiscussed in Sect ion 4, and inspection/moni-toring procedures are addressed in Section 5

The remaining sections o the guide addressimplementation o practices to comply withthe permit and periodic evaluation o yourSWPPP

Prepare your SWPPP beore submitting an NOI

or permit application or coverage!

What is a SWPPP?

A SWPPP is a site-specic, written document

that:

Identies potential sources o stormwater

pollution at the industrial acility;

Describes stormwater control measures that

are used to reduce or eliminate pollutants

in stormwater discharges rom the industrial

acility; and

Identies procedures the operator will use

to comply with the terms and conditions o

the 2008 MSGP or a State general industrial

stormwater permit.

You are required to develop your SWPPP to

address the specic conditions at your site and

keep it up-to-date to refect changes at your

site both or your use and or review by the

regulatory agencies responsible or overseeing

your permit compliance.

Developing Your Stormwater Pollution Prevention Plan: A Guide for Industrial Operators 5

To assist permittees in their recordkeeping,EPA has developed an Additional MSGPDocumentation template, which is available atwww.epa.gov/npdes/stormwater/msgp Thistemplate, developed or permit holders subjectto the 2008 MSGP, is available in MicrosotWord and can be modied as necessary toaddress State-specic permit requirements

2.C Stormwater Pollution PreventionTeam (Step 1)

The rst step in developing the SWPPP is toidentiy the stormwater pollution preventionteam The stormwater pollution preventionteam is responsible or assisting the acilitymanager in developing the acilitys SWPPPas well as implementing and maintainingstormwater control measures, taking correc-tive action where necessary to address permitviolations or to improve the perormance o

control measures, and modiying the SWPPPto refect changes made to the control mea-sures Since industrial acilities dier in sizeand complexity, the number o team memberswill also vary The stormwater pollution pre-vention team should consist o those peopleon-site who are most amiliar with the acilityand its operations and responsible or ensur-ing that necessary controls are in place toeliminate or minimize the impacts o storm-water rom the acility

A key member o the stormwater pollution

prevention team (or some acilities, thismay be the only member) is the person withprimary responsibility or developing andoverseeing acility activities necessary to com-ply with the permit This should be someonewho will be on-site on a daily basis and whois amiliar with the acility and its operationsThis person will also likely have primaryresponsibility or ensuring that inspectionsand monitoring activities are conducted I anEPA or State inspector visits the acility, thisperson will be the main point o contact orthe SWPPP

A typical SWPPP includes the ollowingelements:

Stormwaterpollutionpreventionteam;

Sitedescription;

Summaryofpotentialpollutantsources;

Descriptionofcontrolmeasures;

Schedulesandprocedures;

Documentationtosupporteligibilitycon-siderations under other ederal laws; and

CerticationoftheSWPPP.

EPA has developed a model Industrial SWPPPTemplate, which can be ound in Appendix A,and on EPAs website at www.epa.gov/npdes/stormwater/msgp This template, developedor permit holders subject to the 2008 MSGP,is available in Microsot Word and can becustomized to address SWPPP requirements

in dierent State NPDES permits

Where your acility has other written pro-cedures in place, such as a Spill Prevention,Control and Countermeasure (SPCC) Plan oran Environmental Management System (EMS)developed or a National EnvironmentalPerormance Track acility, your SWPPP canreerence the portions o those documents inlieu o duplicating that inormation in yourSWPPP In these instances, you should keepcopies o the relevant portions o those docu-ments with your SWPPP

Additional SWPPP Documentation

Ater you become authorized under thepermit, you will need to keep records on anyimplementation activities required under yourpermit, including records related to inspec-tions, maintenance, monitoring results, andcorrective actions This additional documen-tation, although separate rom the actualSWPPP, should be kept with the SWPPP sothat all o your NPDES stormwater records areled in one central location (see Section 7)

EPAs 2008 MSGP includes the requirements

or a SWPPP in Part 5 o the permit.

In your SWPPP, identiy the sta members

(by name or title) that comprise the acilitys

stormwater pollution prevention team as well as

their individual responsibilities. Make sure you

keep this inormation up-to-date as sta members

change.

Each member o the stormwater pollutionprevention team should have ready access toeither an electronic or paper copy o appli-cable portions o the industrial stormwatergeneral permit and the SWPPP

2.D What Do I Need to Do to Complete MySWPPP?

Ater identiying your pollution preventionteam, you are ready to complete the next threesteps in the development o your SWPPP:

Step 2: Assessing your site and activities(Section 3);

Step3: Selecting control measures(Section 4); and

Step 4: Developing procedures or inspec-tions and monitoring (Section 5)

Section 6 describes nal steps necessary tocomplete your SWPPP and to obtain permitcoverage Section 7 suggests how recordsrelating to permit compliance should be kept

Qualifed Personnel Members o your

stormwater pollution prevention team and those

conducting inspections and monitoring activities

should be qualied personnel. EPA denes

qualied personnel as those who posses the

knowledge and skills to assess conditions and

activities that could impact stormwater quality

at your acility, and who can also evaluate the

eectiveness o control measures.

Consider adding a stormwater management

component to employee job descriptions and

annual reviews, as appropriate to specic

jobs. Oten these requirements compliment

existing tasks such as maintaining a clean work

area; promptly cleaning up spills and leaks;

perorming regularly scheduled equipmentmaintenance; and properly storing all chemicals,

oils, and other liquid pollutants.


10/45


This section describes how to collect the inormation needed or your SWPPP Thisinormation includes:

An assessment o the activities perormed at your acility this assessment will helpidentiy potential pollutant sources

An evaluation o existing sampling data a review o sampling data will showwhere past problems have occurred

Preparing maps o your acility site maps will identiy the location o industrialactivities, pollutant sources, control measures, and the direction o stormwater fow

3.A Conduct an Assessment o the Activities Perormed at Your FacilityThe rst step in developing a SWPPP is to gain a thorough understanding othe activities conducted and equipment located at your acility to be able toidentiy potential pollutant discharge concerns To complete this step, you willneed to conduct a detailed walk-through o your acility to identiy industrialmaterials or material handling activities exposed to stormwater (see text boxbelow), any stormwater controls already in place at your acility, the direc-tion o stormwater fow through and rom your acility, and the location o allstormwater outalls I possible, you should conduct your walk-through dur-ing a rain event so that you can observe the fow o stormwater on your siteIn addition to your walk-through, you should communicate with ellow siteemployees who may be more amiliar with daily operations than you so that you can

thoroughly identiy any activities that may contribute stormwater pollutants, but thatmay not be readily visible during a routine walk-through (eg, to identiy activitiesthat are not perormed on a routine basis)

Section 3: Site Assessment and

Planning (Step 2)

How Does EPA Defne Industrial Materials and Material Handling

Activities?

Industrial materials or activities include, but are not limited to: material handlingequipment or activities; industrial machinery; raw materials; industrial production and

processes; and intermediate products, byproducts, nal products, and waste products.

Material handling activities include, but are not limited to: the storage, loading and

unloading, transportation, disposal, or conveyance o any raw material, intermediate

product, nal product or waste product. See 40 CFR 122.26(g).

Develop a list o industrial

activities at your site exposed

to stormwater. Identiy these

activities on your site map.

What to Include in

Your SWPPP


11/45


The acility assessment will reveal locationswhere industrial materials or material han-dling activities may be contributing stormwa-ter contaminants, and help you identiy themost important pollutant sources The ollow-ing approach is suggested or completing youracility assessment:

Identifcation o Activities Exposed toStormwater As you conduct your acilityassessment, make a list o the industrialactivities exposed to stormwater (eg, mate-rial storage; equipment ueling, maintenance,and cleaning; cutting steel beams) Note theirlocation so they can be identied on the sitemap

Inventory o Materials and Pollutants Makea list o the materials and pollutants (eg,crankcase oil, zinc, suluric acid, and clean-ing solvents) associated with each identied

activity, including pollutants associated withthese materials, based on how they are stored,handled, disposed, etc Note whether thesematerials are exposed to stormwater, or havethe potential to be exposed to stormwater Howmaterials are stored and handled has a bearingon the potential or stormwater pollution

Areas with Spill or Leak Potential Documentwhere potential spills and leaks may occur,and speciy the outall(s) that could beaected by such spills and leaks Documentall signicant spills and leaks that actuallyoccurred at exposed areas, or that drained to

a stormwater conveyance, in the three yearsprior to the date you prepare or amend yourSWPPP You should consider spillage andleakage o all types o materials when prepar-ing or and documenting such releases

Presence o Non-Stormwater Discharges A non-stormwater discharge is any discharge romyour acility this is not composed entirely orainall or snowmelt runo Non-stormwaterdischarges oten come rom potable watersources or process wastewater dischargesWith ew exceptions, the discharge o non-stormwater as runo rom your acility is pro-

hibited unless it is specically allowed underan NPDES permit

You must evaluate or the presence o non-stormwater discharges and be able to demon-strate that all unauthorized non-stormwaterdischarges have been eliminated prior toobtaining coverage under a stormwater permit(or that any other discharges are otherwisecovered under a dierent NPDES permit)Conduct your evaluation during a period odry weather (no rain or at least the previousthree days) Walk your site and evaluate eachoutall to identiy any locations with fowingor stagnant water or discharging liquid; thepresence o such water or liquid that would beindicative o a non-stormwater discharge Youshould try to identiy the source o the wateror liquid, and determine i it is one o theallowable non-stormwater discharges identi-ed below or otherwise in need o urtheraction to eliminate the source You shouldalso identiy any indicators o past or inter-mittent non-stormwater discharges (such asevidence o stains at the outall)

Identiy locations o potential spills and leaks

that could contribute pollutants to stormwater

discharges, and the corresponding outalls that

would be aected. Review past records o all

signicant spills and leaks that occurred in

areas exposed to stormwater or that drained to a

stormwater conveyance over the past three years,

and provide a summary or copy o such records in

your SWPPP.


For each o the activities identied above, create

an inventory o the materials associated with

each activity (this may be easiest to do in a

table). Identiy whether these materials are orhave the potential to be exposed to stormwater.

Also, identiy any pollutants associated with these

materials based on how they are stored, handled,

disposed, etc.

in Figure 3

3.C Develop General Location and SiteMaps

The nal step in the site assessment processis to document the results o your site assess-ment on a detailed site map I you havealready developed a site map or an earlierpermit, you should modiy the map as neces-

sary to refect changes at your acility, includ-ing changes to any o your control measuresor industrial activities

Your SWPPP must include both a general loca-tion map and a detailed site map The ollow-ing is a discussion o what is required or eachtype

General Location Map

A general location map is helpul to identiynearby, but not necessarily adjacent, water-bodies around your acility Include in yourSWPPP a general location map (eg, USGeological Survey (USGS) quadrangle map,or other large scale area map) with enoughdetail to identiy the location o your acil-ity and al l nearby receiving waters that mayreceive your stormwater discharges Create aUSGS map or your area by using the USGSNational Map Viewer (http://nmviewogc.cr.usgs.gov/viewer.htm) Maps can be printed

or saved as PDF documents and inserted intoyour SWPPP

Develop a general location map o your acility

that shows:

It may also be helpul to include roads or political

boundaries to better locate your acility.

appropriate control measures (Section 4) andmonitoring locations (Section 5), you shouldrevise your site map to refect this inormationand any additional changes identied as youdevelop your SWPPP I you are unable to tall the inormation on one map, use multiplemaps to provide a ull characterization o theinormation described above Also, i activities

and conditions change at your site during theterm o the NPDES permit, you should updatethe map as described in Section 6C o thisguide An example o a site map is included(see Figure 4) and in Appendix C

Site Map

Develop a map o your site that includes,among other things, the ootprint o all build-ings, structures, paved areas, and parkinglots The site map is intended to show thedirection o stormwater fow throughout youracility and the potential pollutant sources

that may come into contact with your storm-water runo

EPA recommends that you develop a rst drato the site map based on the inormation col-lected during your assessment Ater you select

Control measures are the best management practices (BMPs) or other structural ornon-structural practices that are used to prevent or reduce the discharge o pollutantsin stormwater Structural control measures, as the name implies, ocus on installationo hard structures to control discharges Structural controls include practices suchas vegetative swales, collection and reuse o stormwater,inlet controls, snow management, inltration devices, andwet retention measures Non-structural control measuresare intended to prevent or reduce the generation o pol-lutants in stormwater and/or the volume o stormwaterruno using practices that ocus on acility operations and

procedures Examples o non-structural control measuresinclude procedural practices such as employee trainingsand the posting o signs that raise sta awareness tothe BMPs and procedures in place to control stormwaterpollutants

A combination o preventive and active treatment control measures usually resultsin the most eective stormwater management or minimizing the osite discharge opollutants in stormwater runo Most control measures require regular maintenanceto unction as intended Some control measures have simple main-tenance requirements, while others may require more extensiveupkeep in order to maximize their perormance Note that identiy-ing weaknesses in current acility practices will help permitteesdetermine appropriate control measures or use at the site

General Stormwater Management Principles

In most industrial stormwater permits, including the 2008 MSGP,the site operator is given the fexibility to select the type o controlmeasures, including specic technologies, which he/she believes arebest suited to the acility and that will meet the permits require-ments This fexibility is necessary given the variability o eachindustrial operation, the dierences in the topography rom site tosite, and the dissimilarities in the activities and materials exposed tostormwater However, there are certain general principles o storm-water management that are common to all sites, and that can beused by operators in their selection and design o control measures

These general principles, listed below, should be considered as a wayto maximize the perormance o control measures at your site

Pollution prevention The best way to prevent stormwater pollution is to mini-mize the use o water contaminants in your industrial activities When selectingcontrol measures or the acility, you should ocus on controls that are gearedtoward reducing pollutants at the source to prevent stormwater pollution Sourcecontrol practices include maintaining equipment, picking up trash and debris,training site sta on appropriate spill procedures, and proper materials manage-ment and storage

Section 4: Selecting Control

Measures (Step 3)

Efuent limits = stormwater control

requirements. In the 2008 MSGP, as with

most state industrial stormwater general

permits, stormwater control measures are those

structural or non-structural practices that are

used to achieve the permits efuent limits.

What does minimize

mean?

The technologybased limitsincluded in EPAs 2008 MSGP

require that you minimize (i.e.,

dened as reduce and/or eliminate)

stormwater exposure to pollutants

using control measures that are

technologically available, economi

cally practicable, and achievable in

light o best industry practice.


18/45


Minimizing exposure Another eectiveway to minimize stormwater pollution is toeliminate opportunities or stormwater tocome into contact with industrial activi-ties and polluting materials You shouldlook or opportunities to relocate industrialactivities/materials to covered or containedareas and to properly store and transport

any accumulated scrap or waste material

Combining controls Combined controlmeasures are oten more eective thancontrol measures in isolation For example,good housekeeping will oten go a long wayto minimize stormwater pollution but ismore eective when combined with mini-mizing the exposure o signicant materi-als or activities and a structural control,such as inlet protection

Examining your sites pollutant sources Understand the type and quantity o pol-

lutants that could contaminate stormwaterleaving your acility Use your knowledgeo the potential pollutants to drive yourselection and design o eective controlmeasures

Maximizing infltration Onsite inltra-tion reduces overland runo, improvesgroundwater recharge, and augments basefow in local streams You should look oropportunities to minimize impervious areaand increase areas where stormwater caninltrate on-site Keep in mind, however,

that the use o onsite inltration typicallymust be combined with other control mea-sures to avoid ground water contamination

Using existing vegetated areas Openvegetated swales and natural depressionscan be used to dissipate energy in overlandfow and reduce erosion Vegetated swalesand natural depressions can increase inl-tration and, in some cases, promote uptakeo metals and nutrients by plants

Buering on-site or adjacent waterbodiesor drainage systems Maintain or restore

vegetated buer zones between your acili-tys impervious areas and adjacent suracewaters

Using structural practices (as applicable) When non-structural control measuresare not eective in preventing stormwatercontamination, structural control measures(eg, swirl separators, sand lters, retentionbasins, etc) may be needed to treat storm-water beore it leaves your acility

EPAs Technology-Based DischargeRequirements

The ollowing sections describe the 12 catego-ries o discharge requirements (or efuentlimits) required by the 2008 MSGP Althoughthe wording o these requirements may beunique to the EPA permit, many State permitsinclude requirements that are similar to the2008 MSGP

4.A Minimize Exposure

The rst step in an eective stormwater con-trol program is minimizing exposure o man-uacturing, processing, material storage areas,loading and unloading areas, dumpsters andother disposal areas, maintenance activities,and ueling operations to rain, snow, snow-melt, and runo by both locating industrialmaterials and activities inside or protectingthem with storm resistant coverings

No Exposure Exemption

EPAsregulationsrecognizetheeffectivenessof

minimizingexposurebyallowingfacilitiestoopt

out o the permit by submitting a No Exposure

Certication when all industrial activities are

protected rom contact with stormwater. The No

Exposure Certication is included as Appendix K

o the 2008 MSGP. Note that industrial materials

do not need to be enclosed or covered i

stormwater runo rom aected areas will not be

discharged to receiving waters or i discharges

areauthorizedunderanotherNPDESpermit.

4.B Good HousekeepingGood housekeeping practices oer a practicaland cost-eective way to maintain a clean andorderly acility to prevent potential pollutionsources rom coming into contact with storm-water Good housekeeping practices also helpto enhance saety and improve the overall

work environment To eectively documentin your SWPPP that you are including goodhousekeeping procedures at your site, youshould establish protocols to reduce the pos-sibility o mishandling materials or equipmentand train employees in good housekeepingtechniques An eective good housekeepingprogram not only benets stormwater qualitybut makes the acility a clean, sae place oremployees and clients

Common areas where good housekeeping

practices should be ollowed include areaswhere trash containers are kept and adjacentareas, material storage areas, vehicle andequipment maintenance areas, and loadingdocks Involving employees in routine moni-toring o housekeeping practices has proven tobe an eective means o ensuring the contin-ued implementation o this control measure

Labeling Storm Drains A good stormwater

awareness practice is to label all storm drains

on your industrial acility with a No Dumping

Drains to Stream or similar message. I select

drains at your acility discharge to the sanitary

sewer system or to a sump (or example, at

a wash rack), you should label those with a

Drains to Sanitary Sewer or similar message.

4.C MaintenanceA good maintenance program requires regu-lar inspections, testing, and the preventivemaintenance and repair o industrial equip-ment (stationary and mobile) and industrialsystems Maintenance programs are intendedto ensure that structural control measures

and industrial equipment are kept in goodoperating condition and to prevent or mini-mize leaks and other releases o pollutants(see Section 4D or more specic inorma-tion) I you notice a deciency or otherwisend that your control measures or industrialequipment need to be replaced or repaired toensure proper unctioning, and to avoid leaksor other releases, you must make the neces-sary repairs or modications, typically priorto the next wet weather event and as expedi-tiously as practicable

Facilities with good maintenance programswill keep a maintenance log that tracks theregular maintenance o industrial equipmentand stormwater control measures The logprovides a maintenance history or each pieceo equipment and demonstrates to regulatoryauthorities that you have implemented themaintenance program outlined in your SWPPP

4.D Spill Prevention and ResponseProcedures

Spills and leaks, together, are the largestsource o industrial stormwater pollutionFor this reason, your SWPPP must identiycontrol measures that are used at your site tominimize the potential or spills, leaks, and

other releases that may come into contactwith stormwater Among the practices thatshould be in place at your site are plans oreective response to spills i or when theyoccur I your acility has more than 1,320gallons o oil storage capacity in abovegroundtanks you may also be required to develop aSpill Prevention, Control and Countermeasure(SPCC) plan consistent with 40 CFR 1121

Employees must be aware o notication

procedures in the event o a spill or leak,

including when to contact appropriate acility

personnel, emergency response agencies, and

regulatory agencies. State or local requirements

may necessitate reporting o spills or other

prohibited discharges to local emergency

response, public health, or drinking water supply

agencies. Contact inormation must be posted

in locations that are readily accessible and

available to employees. Where a leak, spill, or

otherreleasecontainingahazardoussubstance

or oil in an amount equal to or in excess o a

reportable quantity established under either

4.F Management o RunoSimilar to erosion and sediment controls, themanagement o stormwater runo that fowsthrough your site is an eective way to reducethe pollutants that are discharged rom yoursite Where you employ structures or practicesthat are intended to divert, inltrate, reuse,

or otherwise reduce stormwater runo so asto reduce the discharge o pollutants, yourSWPPP must include a description o thosecontrols Appropriate measures are highlysite-specic, but may include vegetativeswales, berms, collection and reuse o storm-water, inlet controls, snow management, inl-tration devices, and wet retention measures

As mentioned previously, a combination o pre-

ventive and treatment control measures usuallyresults in the most eective approach to storm-water management or minimizing the ositedischarge o pollutants in stormwater runo

4.G Salt Storage Piles or Piles ContainingSalt

Salt is commonly used or deicing and othercommercial or industrial purposes, includingmaintenance o paved suraces Salt piles orpiles that are predominantly composed o othermaterials that contain some salt typically mustbe covered or enclosed and otherwise isolatedrom coming into contact with stormwater(eg, good housekeeping, diversions, contain-

ment) Piles do not need to be enclosed orcovered i stormwater runo rom the piles isnot discharged or i discharges rom the pilesare authorized under another NPDES permit

To eectively document in your SWPPP thatyou are minimizing exposure o these pilesto stormwater, you should consider creating achecklist to veriy that salt loading and ofoad-ing operations occur within contained areaswith appropriate measures in place to preventthe track out o salt rom the contained areas

When selecting control measures, be careul not

to violate local building or re codes and other

ordinances. An example would be constructing

a shed or storage o chemicals and then nding

out rom the re department that you are in

violation or locating the shed too close to themain building, not equipping the shed with

sprinklers or other re control device, and not

properly labeling containers.

4.J NonStormwater DischargesIn Section 3A, this guide discussed theassessment o allowable and prohibited non-stormwater discharges at your site As statedin that section, unauthorized non-stormwaterdischarges cannot be discharged rom youracility unless specically authorized by a

separate, individual NPDES permit YourSWPPP should describe the assessmentyou conducted under Section 3A, how youeliminated any unauthorized non-stormwaterdischarges, and your plans to prevent unau-thorized non-stormwater discharges at youracility

4.K Waste, Garbage, and FloatableDebris

You are responsible or making sure thatstormwater runo does not carry waste, gar-bage, and foatable debris to receiving watersTo veriy compliance with this requirement,you should identiy and implement control

measures (eg, good housekeeping, sweep-ing, keeping lids closed on dumpsters) tokeep exposed areas ree o such materialsAlternatively, your SWPPP should identiyhow you will intercept and properly dispose othese materials beore they leave your acility

4.L Dust Generation and Vehicle Trackingo Industrial Materials

As an operator, you are responsible orminimizing generation o dust and o-sitetracking o raw, nal or waste materials Dustcontrol practices can reduce the activities andair movement that cause dust to be gener-

ated rom disturbed soil suraces Airborneparticles pose a dual threat to the environ-ment and human health Dust can be car-ried osite, thereby increasing soil loss romdisturbed areas and increasing the likelihoodo sedimentation and water pollution Controlmeasures to minimize the generation o dustinclude:

Sprinkling/Irrigation Moistening theground surace with water is an eectivedust control method or haul roads andother trac routes

Vegetative Cover By establishing a vegeta-tive cover on areas that will not see vehicletrac, exposed soil is stabilized and windvelocity at ground level can be reduced,thus reducing the potential or dust tobecome airborne

Mulch Mulch is a quick and eective, butnot permanent, means o dust control ornewly disturbed areas

Wind Breaks Wind breaks can be trees orshrubs let in place during site clearing orconstructed barriers such as a wind ence,

snow ence, tarp curtain, hay bale, cratewall or sediment wall The break reduceswind velocity, minimizing airborne trans-er o soil o site

Tillage Deep tillage in large open areasbrings soil clods to the surace where theyrest on top o dust, preventing it rombecoming airborne

Stone Stone can be an eective dust deter-rent or construction roads and entrancesor as a mulch in areas where vegetationcannot be established

Spray-on Chemical Soil Treatments(Palliatives) Examples o chemical adhe-sives include anionic asphalt emulsion,latex emulsion, resin-water emulsionsand calcium chloride Chemical pallia-tives should be used only on mineral soilsWhen considering chemical applicationto suppress dust, determine whether thechemical is biodegradable or water-solubleand what eect its application could have

on the surrounding environment, includingwaterbodies and wildlie

To reduce vehicle tracking o materials andsediment, the operator should keep stored orspilled materials away rom all roads withinthe site Specic measures such as setting upa wash site or separate pad to clean vehicles

prior to their leaving the site may be eectiveas well

4.M Numeric Efuent Limitations Basedon Efuent Limit Guidelines

Some industrial activities identied in indus-trial stormwater permits also have Federalnumeric efuent limits (called efuent limita-tion guidelines) that must be achieved instormwater discharges The efuent limits aremaximum concentrations or levels o specic

Recommended Routine Facility InspectionSequence

Although you are given the discretion todetermine how best to conduct your inspec-tion, EPA recommends that your inspectionollow a sequence that corresponds to howraw materials arrive at your site and are

stored or processed in areas exposed to storm-water, and to how intermediate or nishedproducts are stored, processed, or transportedrom your acility Accordingly, the ollowingrecommended inspection sequence wil l helpensure that you conduct a thorough routineinspection at your acility Whichever processyou determine is appropriate or your acility,you are required to describe that approach inyour SWPPP

1 Plan your inspection: Develop a consis-tent process to ensure that you inspectall areas One method to ensure that yourinspections are consistent and thorough isto create a checklist (or make notes on acopy o your SWPPP) o areas to inspectUse as a resource your updated site mapidentiying the locations o industrial

activities exposed to stormwater, storm-water conveyances and discharge points,and any BMPs

2 Evaluate the area where raw materials aredelivered Are these areas contained oris there potential or stormwater to carryspills or pollutants away rom the droparea? I so, can these pollutants leave yoursite to an adjoining acility, storm drain,or surace water? I so, additional controlmeasures should be implemented

3 Are raw materials stored in a contained

area with overhead cover, berms, or othersecondary containment? I not, do the rawmaterials have the potential to contributeto stormwater pollution?

Note: Single-wall chemical containersneed to be located within secondarycontainment structures, behind berms,or covered to prevent stormwater con-tamination rom an accidental release ocontainerized chemicals Similarly, solidmaterials with the potential to containpollutants (ie, scrap material or wrecked

vehicles) should include secondarycontainment

4 Is equipment maintenance and uelingconducted in appropriately containedareas? Are spill kits present and ullin areas where a liquid spill could beexpected?

5 Do the industrial processes occur in cov-ered and contained areas?

6 Where do you store waste material?

Note: I the waste material has the poten-

tial to contaminate stormwater it must bestored in a contained area or otherwisecontrolled Be sure to evaluate the acil-ity bone-yard and scrap all equipmentthat is out-o-date and not intended to bereused

EPAs 2008 MSGP requires quarterly routine

acility inspections o all areas where industrial

materials or activities are exposed to stormwater,

and o all stormwater control measures used

to comply with the euent limits contained

in the permit. Inspections must be conducted

by qualifed personnel, including at least one

member o your pollution prevention team,during regular business hours. You must speciy

the relevant inspection schedules in your

SWPPP document as required in Part 5.1.5.

The 2008 MSGP requires that at least one o the

our quarterly inspections each year be conducted

when a stormwater discharge is occurring.

You should check your industrial stormwater

general permit to determine i it establishes

exceptions to the inspection requirements orcertain types o sites. For example, 2008 MSGP

Part 4.1.3 identies exceptions to routine visual

inspections or inactive or unstaed sites.

Invest in an inexpensive digital camera to

photo-document your inspections. Maintaining

a photo history o inspections and control

measurescanhelpyoutorecognizeif

conditions changed or your control measures are

degrading. Photographs can also help provide

documentation to EPA or state inspectors that

control measures are being maintained and

replaced as needed.

7 Is the nished product appropriately con-tained or potential pollutant sources?

8 Following the internal evaluation, walk theperimeter o your site and look or evidenceo stormwater dischargesparticularlystains rom oil and grease or chemicalsShould you observe these, look at the dis-charge area and consider additional controlmeasures You should specically observeall stormwater outalls where stormwaterleaves your acility

9 Following each inspection, you will needto make note o control measures thatrequire maintenance, or that need to bereplaced, and make sure that the SWPPPand site map are current regarding indus-trial activities and potential pollutants

10 Finally, where appropriate, repair orreplace worn or ineective control mea-

sures as soon as possible but certainlybeore the next orecasted precipitationevent Routine Facility Inspection Reports

Your routine acility inspections will needto be recorded and documented Generally,a standard inspection report is taken intothe eld and completed or each inspectionYou should include in your SWPPP a copyo the standard inspection orm you willuse An example routine acility inspectionorm can be ound in the Additional MSGPDocumentation Template on EPAs website atwww.epa.gov/npdes/pubs/

you get inspected, EPA or the State agency will

expect that all control measures identied in

your SWPPP to be current and to be eectively

implemented at your acility.

5.B Visual AssessmentsThe second component o an eective storm-water inspection program is periodic visualassessments o the stormwater dischargingrom your acility Visual assessments are con-ducted on samples taken during a storm event,and require that you make observations o thestormwater sample in order to qualitativelyassess the nature o your discharge based onseveral visual parameters This requires thatyou collect a stormwater sample in a clean,

clear jar and look at the sample in a well litarea Generally, a sample must be collectedrom each stormwater discharge location asso-ciated with industrial activity The purposeo conducting visual assessments is to makesure that stormwater discharges are ree romobjectionable characteristics (ie, pollutantsyou can see) Should you observe objection-able characteristics, you should backtrackupstream rom the sample collection locationto identiy potential sources o the pollutants

Some pollutants may be present in stormwaterbut cannot be seen; or this reason EPA or yourState may require benchmark or efuent limitmonitoring depending on the acility SIC codeor industrial sector See Section 5D or moreinormation on monitoring

Most industrial stormwater permits do notrequire visual assessment samples to be col-lected consistent with 40 CFR Part 136 pro-cedures (the Clean Water Act guidelines or

Your SWPPP should describe the routine acility inspection process in enough detail that a member o your sta could complete an

inspection by ollowing the description in the SWPPP. The SWPPP description should include:

1. Person(s) or positions o person(s) responsible or conducting the routine acility inspections

At least one member o your stormwater pollution prevention team should be involved in the routine acility inspections. Consider

involving employees who regularly work in areas where stormwater may come into contact with industrial activity or materials.

5.D Documentation o MonitoringProcedures

Your industrial stormwater general permit mayinclude requirements to conduct stormwaterdischarge monitoring The type o monitor-ing you are required to conduct will likely bebased on your type o industrial activity Not

all types o industrial activity will be requiredto collect stormwater discharge samples,however, i your acility is required to conductmonitoring (such as benchmark monitoring orefuent limitation guideline monitoring), youmust describe the procedures you will use tocarry out this monitoring in your SWPPP

EPA has prepared anIndustrial StormwaterMonitoring and Sampling Guide (availableat www.epa.gov/npdes/stormwater/msgp )

that will support this guide TheIndustrialStormwater Monitoring and Sampling Guideprovides a more detailed description o moni-toring approaches and procedures that arerecommended than is included in this guide

As a general matter, your stormwater dischargesamples will be taken at your acilitys storm-

water outall locations, not at locations withinyour acility Some stormwater general permitsallow you to sample at only one outall whenmultiple outalls at your acility have similarindustrial activities, control measures, exposedmaterials, and runo coecients Outalls thathave these similar characteristics are calledsubstantially identical outalls or represen-tative outalls See your industrial stormwatergeneral permit or more inormation

IncludeinyourSWPPP,adescriptionofthefollowingmonitoringrequirements:

1. What you need to monitor

Make sure your SWPPP clearly identiies the parameters you need to monitor, and any applicable benchmark concentrations or

eluent limits associated with each parameter.

2. Where you need to monitor

Yoursitemapshouldidentifytheoutfallsatyourfacility.InyourSWPPP,identifyatwhichoutfallsyouwillberequiredto

Section 6: Completing Your SWPPP

Now that you have conducted a site assessment o your acility, developed maps,

selected control measures, and developed procedures or inspections and monitoringYou are almost done with your SWPPP! The last step is to make sure all this inorma-tion is organized into a single document (your SWPPP) and to obtain NPDES permitcoverage

6.A Finish your SWPPPThe inormation you put together as part o Sections 3 through 5 make up the con-tents o your SWPPP There are only two more steps or you to nish beore yourSWPPP is complete:

ConductanalreviewofyourSWPPP;and

SignandcertifyyourSWPPP

Review Your Draft SWPPP

You should review the SWPPP requirements in your industrial stormwater generalpermit to ensure that your SWPPP includes all required elements For example, in the2008 MSGP, the SWPPP requirements are in Part 5 Check o all the SWPPP permitrequirements as you veriy that they have been met Also, develop a nal copy o yoursite map and make sure that all required elements are addressed

EPA recommends that you have both your stormwater pollution prevention team, andsomeone who was not involved in developing the SWPPP, review your drat SWPPP

Sign and Certify Your SWPPP

The last step in completing your SWPPP is to have a acility executive or duly autho-rized representative o that executive sign and certiy that the SWPPP meets all therequirements in the general permit This signature demonstrates that the SWPPP wasreviewed by someone who has operational control over the acility (ie, can commitresources to implementing the SWPPP and ensuring compliance with the permit)You should check your general permit to determine which person is required to signand certiy the SWPPP Note that the signatory requirements or the 2008 MSGP areound in Appendix B, Subsection 11 o EPAs 2008 MSGP

6.B Obtain NPDES Permit CoverageImportant! Beore obtaining permit coverage, you should read the appropriate industrial

stormwater permit and develop your SWPPP.

Most permits require that you develop your SWPPP beore you can obtain NPDES per-mit coverage or your industrial stormwater discharges However, in some instances,the permit may provide you with additional time to complete or update a SWPPP aterpermit coverage is obtained Nevertheless, it is recommended that your SWPPP becompleted at least in drat orm prior to applying or permit coverage, even in thoseStates where additional time is granted

Obtaining Coverage Under a General Permit

To obtain coverage under a State industrial stormwater general permit, you will typi-cally need to ll out and submit an application orm, oten called a Notice o Intent or


38/45


NOI Submitting an NOI orm to the permit-ting authority indicates your certication thatyou have met the eligibility requirements orcoverage under the permit, and your agree-ment to abide by the terms and conditions othe general permit Depending on the permit,you may be authorized to discharge immedi-ately or at some later time In some cases, you

are not authorized to discharge until the Statehas notied you accordingly EPAs 2008 MSGP(see Part 131) uses a 30 to 60-day waitingperiod ollowing the receipt o a acilitys com-plete NOI The waiting period expires whenthe permits status changes rom waiting toactive on the Agencys eNOI website

6.C Updating Your SWPPP

Your SWPPP is a document that will need tobe reviewed and updated on a regular basisWhenever you nd the need to change a pro-cedure that is described in your SWPPP or tomodiy a control measure described therein,you must update the SWPPP to refect thosechanges as quickly as practicable Should theSWPPP require modication to document cor-rective actions, a new certication statementmust be signed and dated upon completion othe revision

Below are some examples o events that, ithey result in a change in control measures orprocedures, will require prompt revision o theSWPPP to refect the new acility conditions

Remember, revisions to the SWPPP to docu-ment corrective actions requires a new signedand dated certication statement by the respon-sible ocial All other changes must be signedand dated by the person preparing the change

In the interim between the annual inspection and completed SWPPP

revision, keep a copy o the original SWPPP with your handwritten

notes or SWPPP modications at the acility. Should you be

inspected beore the revised SWPPP is complete, the copy with your

notes can be used to demonstrate the changes that will be in the

revised document.

Documentation to Support EligibilityConsiderations Under Other Federal Laws

The 2008 MSGP requires that you keep with

your SWPPP the documentation supporting

your eligibility pertaining to endangered species

requirements, historic properties requirements,

and NEPA review requirements described in

the permit (see Part 5.1.6 o the permit). State

industrial stormwater permits may have other

documentation requirements.

Completing your SWPPP and obtaining NPDES permit coverage is an important steptowards complying with your State or EPA Clean Water Act requirements Havingcompleted these steps, you are now ready to begin documenting your compliancewith the requirements o your permit EPAs 2008 MSGP and many State permitsrequire you to keep records o any activities at your site that are related to your com-pliance, such as conducting inspections, visual assessments, stormwater dischargemonitoring, and corrective actions

As you conduct inspections, monitoring, corrective actions, and other permit imple-mentation activities, you will generate additional records, such as inspection reportsand monitoring results Keep this additional documentation on-site with your SWPPP,

and ensure these records are accessible, complete, and up-to-date so that they demon-strate your ull compliance with the conditions o your permit

Some examples o this additional documentation include:

Permit records copies o the NOI or permit application submitted, any lettersreceived rom the permitting authority, and a copy o your general permit

Spill records dates o any incidences o signicant spills, leaks, or other releasesthat resulted in a discharge o pollutants, the circumstances leading to the release,actions taken in response to the release, and measures taken to prevent the recur-rence o a release

Employee training records keep copies o all employee training records, includingdates, who was trained, and the training topics

Maintenance records retain copies o all maintenance and repairs o control mea-sures, including dates o regular maintenance, dates when maintenance needs werediscovered, and dates when control measures were returned to ull unction

Inspection records keep copies o all routine acilityinspection reports, quarterly visual assessment reports,and annual comprehensive site inspection reports

Monitoring records retain records o all samplingresults including data collection orms, lab results, anddischarge monitoring reports (DMRs)

Corrective action records keep records o any cor-rective actions and ollow-up activities conducted todemonstrate compliance with the permit
