minimum, the following elements:
o Description of discharge practices, including non-routine
batch discharges;
o Description of stored chemicals;
o Procedures for immediately notifying the POTW of slug
discharges, including any discharge that would violate a
prohibition under 40 CFR 403.5(b), with procedures for
follow-up written notification within five days;
o If necessary, procedures to prevent adverse impact from
accidental spills, including inspection and maintenance of
storage areas, handling and transfer of materials, loading
and unloading operations, control of plant site run-off,
worker training, building of containment structures or
equipment, measures for containing toxic organic pollutants
(including solvents), and/or measures and equipment for
emergency response.
This provision sets forth only the minimal federal
requirements for slug control plans. All POTWs (not just those
required to establish federally-approved pretreatment programs)
may require such plans of any industrial user (not just
significant industrial users) as necessary.
Pursuant to the new amendments, we are now making a wider
distribution of our slug control guidance. The guidance provides
detailed information on how to evaluate industrial users to
determine whether they need slug control plans. It will also
help POTWs decide which measures are necessary for different
industrial users and which kinds of response measures are useful
in particular situations. By supplementing existing or future
categorical standards and numerical local limits, slug control
measures will help reduce influent loadings overall, including
loadings of toxic pollutants and hazardous constituents. In
addition, slug controls can be useful to help POTWs comply with
NPDES effluent limitations on specific chemicals or whole
effluent toxicity.

1. INTRODUCTION
1.1 PURPOSE OF THIS MANUAL
This manual provides guidance to publicly owned treatment works (POTWs)
on how to develop and implement programs to control slug loadings to POTWs.
The manual discusses the two ways to control impacts of slugs on POTVs:
prevention and remediation. The first and preferable way is to prevent slugs
at their source by imposing controls on industrial users. The second
approach, where prevention fails, is remedial response by the POTW.
This guidance is intended to help POTWs implement POTW-wide Slug Control
Programs, and evaluate each of their industrial users to determine whether
they need individual Slug Control Plans. The manual presents a range of Slug
Control Program development options. The recommendations should be useful to
all POTWs interested in controlling slug loadings. A POTW may review the
sections contained in this manual and adapt one of the simplified example Slug
Control Programs in Appendix D to its own needs, or select from among the
recommended procedures to develop or augment its own Slug Control Program.
1.1.1 Control of Slug Loadings
Categorical industrial pretreatment standards and locally-derived
numerical limits generally are used to limit industrial user (IU) pollutant
discharges. However, such controls are often ineffective in addressing
accidental spills or irregular high strength batch discharges, either of which
may be received by the POTW as a "slug loading."
The General Pretreatment regulations define slug loading as any pollutant
discharge violating the specific prohibitions under 40 CFR 403.5(b). These
currently include: (1) fire or explosion, (2) corrosion, (3) obstruction,
(4) interference, or (5) heat [40 CFR 403.5(b)]. The regulations require
that: "All categorical and noncategorical Industrial Users shall notify the
POTW immediately of all discharges that could cause problems to the POTW,
including any slug loadings, as defined by 403.5(b), by the Industrial User"
140 CFR 403.12(f)j.
1-1
-------
Slug prevention may help lUs implement not only the specific prohibitions
above, but also the general prohibition against pass through and interference
[40 CFR 403.5(a) and (b)]. Slug control can supplement existing or future
numerical local limits and may be necessary to help POTVs comply with National
Pollutant Discharge Elimination System (NPDES) effluent limitations on speci-
fic chemicals or whole effluent toxicity.
1.1.2 Elements of a Slug Control Program
The basic elements in developing a comprehensive POTV Slug Control
Program include:
• Evaluating the Need for a Slug Control Program
Identifying potential IU slug sources and their risk categories
Evaluating and/or improving the legal authority to regulate slugs
• Developing an IU Control Program
Requiring designated IDs to develop Slug Control Plans
Inspecting and monitoring designated Ills
• Developing a POTW Slug Response Program
Monitoring for slugs
Developing emergency response procedures and resources.
Chapter 2 discusses how to evaluate the need for a Slug Control Program
and how to develop prevention procedures. Chapter 3 discusses remedial
response procedures.
1.2 SCOPE OF THE SLUG LOADING PROBLEM
The 1985 EPA Report to Congress on the Discharge of Hazardous Wastes to
Publicly Owned Treatment Works contained information on the types, sizes, and
number of generators that dispose of hazardous constituents to sewers, and the
types and quantities of constituents disposed of in this manner. The report
was required by Section 3018(a) of the Resource Conservation and Recovery Act
(RCRA). A 1985 survey undertaken by the Association of Metropolitan Sewerage
Agencies (AMSA), an organization of some of the larger POTVs, was one of the
sources of the Report to Congress. The survey indicated:
1-2
-------
• Sixty percent of POTV respondents to the AHSA survey have received
hazardous wastes as a result of spills to public severs
• Fifty percent report receiving batch discharges from connected
industries.
Among other things, the survey documented discharges around the country
and their impacts on the sever collection system and treatment plant. These
discharges had caused a variety of POTW operational problems, including worker
illness, actual or threatened explosion, biological upset/inhibition, toxic
fumes, corrosion, and contamination of sludge and receiving vaters. Table 1-1
lists some of the potential adverse impacts of slug discharges to the POTV,
its workers, and the environment. Table 1-2, dravn from the AMSA survey as
well as a survey undertaken by Busch (Operations Forum, Journal of the Water
Pollution Control Federation, April 1986), provides examples of actual damage
to the collection system and treatment plant resulting from slugs.
In Gloucester County, Nev Jersey, an electroplating company and corporate
official vere indicted in connection vith the batch discharge of 1,1,1
trichloroethane vhich allegedly killed a sever vorker. Elsevhere, solvent and
organic discharges have caused symptoms such as nausea, skin irritation,
shortness of breath, and headaches among sever vorkers, sometimes requiring
evacuation of collection systems and treatment facilities.
Slugs have also caused harm to the environment, particularly to water and
sludge quality. Preventing these impacts vill be of increasing concern to
POTVs as EPA and the States impose more stringent water and sludge quality
limitations. Some slug loadings limit a POTW's sludge disposal options. For
example:
• A small chemical plant was identified as a significant contributor
(120 Ibs/day) tft mercury to the Passaic Valley Uastevater Treatment
Plant (Passaic, NJ). The concentration of mercury in the sludge
limited the municipality's disposal options.
• The Sioux City Waste Treatment Plant (SCWTP) experienced isolated
slugs of zinc in March and again in April of 1984. Levels as high as
16 mg/1 Zn were observed in the treatment plant influent and both
slugs resulted in an upset of the activated sludge process and
violations of the NPDES discharge limits. In addition to the process
upsets, sludge held in storage lagoons at the facilities became
contaminated vith zinc.

-------
Despite the potential harm from slugs, EPA's pretreatment program audits
and program reviews indicate that less than half of all POTVs subject to the
pretreatment program have spill containment and prevention programs. Problems
in developing such programs include lack of information on materials stored
onsite and inability to identify potential toxic dischargers. POTV system
size and inadequate sampling procedures often make prevention and detection of
slugs difficult.
Nonetheless, some industries and POTVs do have strict slug control and
prevention measures. According to a January, 1987 AMSA membership survey,
virtually all AMSA members require notification of spills, roughly two-thirds
implement comprehensive spill prevention programs, and three-quarters report
that they require industries to take spill prevention measures.
1.3 BENEFITS OF A SLUG CONTROL PROGRAM
By identifying and categorizing potential slug sources and implementing a
program to prevent slugs, POTVs can minimize risks associated with slugs,
often in a cost-effective manner. Implementation of a Slug Control Program
can be a form of pollutant "source reduction." Moreover, continuation of the
Domestic Sewage Exclusion under RCRA will increase the need for better control
of hazardous wastes to POTVs. Slug Control Programs can help reduce loadings
of these wastes to POTVs.
EPA is now aggressively pursuing its policy of imposing whole effluent
toxicity limits on many NPDES dischargers ("Policy for the Development of
Vater Quality-Based Permit Limitations for Toxic Pollutants," 49 FR 9016).
Control of IU slug loadings may reduce POTV noncompliance with toxicity limits
or be a part of a toxicity reduction evaluation (TRE). In addition, slug
control may reduce the need for increasing treatment capacity to meet toxicity
limits when slugs contribute to effluent toxicity.
An industrial user can also benefit from a slug discharge control plan.
Vorker safety can be maximized by preventing spills or by safe handling of
hazardous materials if a spill does occur. In many cases, the economics of
spill cleanup alone can justify preventive measures. Good housekeeping prac-
1-6
-------
tices, employee education, and timely notification to the POTV may be all that
are needed to eliminate or reduce slugs. An industrial user could spend far
less on slug discharge prevention than he would to remedy the effects of an
accidental spill which resulted in a sewer explosion.
Slug control can also help protect IUs' capital investments and prevent
chemical contamination of the site. For example, a well-implemented plan can
protect pipes, valves, treatment and process equipment, floors, and other
structures. The plan may also avoid costly soil and ground-water clean-up
costs should pipes or other structures fail to convey or contain hazardous
wastes.
Finally, through preventive measures an IU may maintain a more accurate
inventory, recycle or reclaim process materials which would otherwise be lost
via slugs to the sewer system. For example, one dairy product manufacturer in
Raleigh, North Carolina regularly discharged stainless steel tanker cleaning
wastes directly to the sewer. Average BODs of 10,000 mg/1, with occasional
slug values in the 30,000 to 40,000 mg/1 range, were typical. To solve the
BOD slug problem, the IU, working with North Carolina State University,
developed a vacuum recovery system and successfully identified a market for
collected whey waste.
1.4 RELEVANT CONTROL EFFORTS
Slug control is not a new concept in pretreatment. In many cases,
dischargers to POTWs are already subject to some slug controls as a result of
existing Federal, State, or local, self-imposed efforts. These efforts may
serve as a reasonable starting point for a POTV's Slug Control Program
development efforts although they may not cover all IUs or all wastes of
concern, or may not be intended primarily to protect the POTV, its workers, or
the environment. A summary of existing Federal programs relevant, or
potentially relevant, to slug control appears in Table 1-3.

1.4.1 Federal Programs
Clean Water Act
Under authority of the Clean Water Act (CVA), slugs are regulated by
various programs. POTW operators are most familiar with NPDES and pretreat-
ment program requirements. However, the CWA also provides EPA with specific
authority to address oil and hazardous substance spills. These authorities
are explained below.
Pretreatment
Section 403.12(f) of the General Pretreatment Regulations requires that
industrial users immediately notify POTVs to which they are discharging of any
slug loading which would violate the specific prohibitions. Toxic Organic
Management Plans (TOMPs) are also relevant to slug control.
TOMPs are addressed in 40 CFR Parts 413, 433 and 469. Three industrial
categories (electroplating, metal finishing, electrical and electronic
components) subject to categorical pretreatment regulations have the option of
developing TOMPs and submitting them to the POTW in lieu of routine monitoring
for total toxic organics. A TOMP must include:
• List of toxic organic compounds used
• Method of disposal used in lieu of discharge
• Procedures for assuring that toxic organics do not spill or leak into
wastewater.
While the applicability and requirements of TOMPs are fairly limited, such
plans may be appropriate for additional lUs. EPA's Guidance Manual for
Implementing Total Toxic Organics (TTO) Pretreatment Standards provides
guidance on the development of TOMPs by lUs.
Best Management Practices (BMPs)
Direct dischargers are subject to the requirements of the NPDES per-
mitting program. Under 40 CFR 125.100-125.104, all direct dischargers who
1-11
-------
use, manufacture, store, handle, or discharge pollutants listed as toxic under
307(a)(l) or as hazardous under 311 of the CVA must follow BMPs for all
activities which may result in the release of "significant" amounts of
pollutants to waterbodies. Such activities include:
• Material storage
• In plant transfer
• Process and material handling
• Loading and unloading operations
• Plant site runoff
• Sludge and waste disposal.
The concept of BMPs may be helpful in developing IU slug controls. BMPs
address eight items: (1) material inventories; (2) material compatibility;
(3) employee training; (4) reporting and notification procedures; (5)
equipment inspections; (6) preventive maintenance; (7) housekeeping; and (8)
security. EPA's manual, NPDES Best Management Practices Guidance Document
describes more fully the elements of BMPs.
Oil and Hazardous Substances
Under Section 311 of the CVA, EPA has the authority to develop regula-
tions to prevent spills of oil and hazardous substances. Section 311 also
requires immediate notification to the Federal Government of discharges to
U.S. waters; see 40 CFR Parts 110, 116 and 117. To date, EPA has promulgated
final regulations to prevent spills from oil handling facilities. These
regulations (40 CFR 112) apply to facilities that handle oil and have the
potential for discharging oil to surface waters in the event of a spill.
While these regulations apply to indirect and direct dischargers, the regu-
lations are not specifically designed to prevent spills from reaching POTWs.
Besides requiring immediate notification to the Federal Government of
discharges to U.S. waters, the regulations also require the preparation and
implementation of spill prevention control and countermeasures, specify
minimum requirements for all onshore and offshore facilities with the poten-
tial for spills to surface waters, and impose additional requirements depend-
ing on the specific operation (e.g., onshore bulk storage tanks, facility tank
1-12
-------
car and tank truck loading). As these regulations apply only to spills from
oil handling equipment and operations, many elements are too specific to be
used to develop general requirements for lUs, although some measures are
potentially applicable to control of POTV slug discharges.
The Resource Conservation and Recovery Act
While RCRA requirements specifically exempt the discharge of hazardous
waste when mixed with domestic sewage, some RCRA requirements may apply to
lUs which are hazardous waste handlers. Three major groups of hazardous waste
handlers are regulated under the Resource Conservation and Recovery Act
(RCRA): generators, transporters, and treatment, storage and disposal
facilities (TSDFs). Two of these groups, generators and TSDFs, are subject to
the spill prevention and response procedures in both Subparts C (Preparedness
and Prevention) and D (Contingency Plan and Emergency Procedures) of 40 CFR
265 and 40 CFR 264. These 40 CFR 265 and 264 requirements are similar, and no
distinction needs to be made between the two for purposes of this manual.
Moreover, POTW personnel should be aware that generators are subject to 40 CFR
265, whereas TSDFs are subject to either 40 CFR 265 or 40 CFR 264 depending on
permitted status (facilities solely classified as hazardous waste generators
not subject to RCRA permitting requirements). As implied by the term
"treatment, storage and disposal facilities", TSDFs are those facilities that
either treat, store or dispose of hazardous wastes. Generators on the other
hand, are not authorized to treat or dispose of hazardous wastes, although
they may store hazardous wastes in containers for less than 90 days. A
special subset of RCRA generators, commonly known as small quantity generators
(i.e., those that generate between 100 and 1000 kg/m of RCRA hazardous wastes)
are only subject to the Subpart C Preparedness and Prevention requirements of
40 CFR 265. Subpart C and D requirements are summarized below.
As stated above, RCRA generators and TSDFs are subject to Preparedness
and Prevention Plan Requirements. The Preparedness and Prevention Plan
requirements have been designed to minimize the possibility and effect of an
explosion, spill, or fire at a RCRA facility. Generally, the facility must
ftave the following equipment:
1-13
-------
• An internal alarm or communications systems
• A device capable of summoning emergency assistance from local
agencies
• Fire and spill control equipment
• Decontamination equipment.
These regulations also specify other requirements such as maintaining
equipment in proper operating condition, routine testing of equipment, and
providing adequate aisle space to allow unrestricted movement of emergency
equipment to any area of the facility.
Facilities must attempt to make arrangements with local authorities
(e.g., police and fire departments) to familiarize them with the layout of the
facility, the properties of the hazardous wastes handled there, and the places
where facility personnel would normally be working. In addition, local
hospitals should be informed of the properties of the hazardous wastes handled
at the facility, and the types of injuries or illnesses that could result from
a fire, explosion, or accidental release.
Large quantity generators and TSDFs are subject to Contingency Plan and
Emergency Procedures Requirements. The contingency plan is a prepared set of
res_:nse3 to an emergency. It should list facility personnel who will serve
as emergency coordinators and the emergency equipment that will be available.
If an evacuation could be necessary for the facility, an evacuation plan must
be included. The plan must describe the arrangements agreed to by the local
police and other government (e.g., fire and hospital) officials pursuant to
the preparedness and prevention requirements discussed above.
Copies of the plan must be maintained at the facility and submitted to
all local governmental units that might be called upon in the event of an
emergency. The plan must also be available to EPA personnel during on-site
inspections. If the facility already has prepared a Spill Prevention, Control
and Countermeasures (SPCC) plan under the Clean Water Act, the SPCC plan may
be amended to incorporate the hazardous waste provisions.
1-14
-------
An employee of the facility designated as the Emergency Coordinator must
be on call at all times to coordinate implementation of the contingency plan
in the event of an emergency threatening human health or the environment. The
Emergency Coordinator must file a written report vith the EPA Regional
Administrator vithin 15 days after an incident.
While EPA has stated that it does not intend the contingency plan to be
triggered when an insignificant amount of waste is released by small spills or
leaking valves, EPA did not include such a de_ minimis provision in the
regulations.
Occupational Safety and Health Act
The Occupational Safety and Health Act (OSHA) [29 CFR, Chapter XVII
(1980)] is also relevant. Under OSHA, an employer has a general duty to
"furnish to each of his employees a place of employment which is free from
recognized hazards that are causing or likely to cause death or serious
physical harm." Exposure to or contact with slug loadings may be one of the
"imminent dangers" prohibited by OSHA standards.
It should be noted, however, that the employer is also required to
develop and implement Emergency Action Plans* that identify the safe means of
escape from fire or other emergencies (29 CFR §1910.36). These plans may not
rely solely on a single safeguard; the employer must provide numerous alter-
natives for minimizing the hazard to ensure employee safety. Employees must
also be trained in emergency plant operation and evacuation procedures. If
spills create an imminent danger, they can be controlled by a number of
alternative methods of hazard minimization, as established in The Emergency
Action Plan. Discharge into local sewers or POTV trunk lines may be necessary
when there is no other option or as a last resort to prevent employee death or
serious physical injury.
*For employers that employ more than 10 workers, the plan must be written; for
employers with 10 or fewer workers the plan may be communicated orally.
29 CFR Section 1910.38(a)(5)(iii).

Superfund Amendments and Reauthorization Act
Section 303 of Title III of the Superfund Amendments and Reauthorization
Act (SARA) requires industries to report three kinds of information:
1. Material Safety Data Sheet (HSDS) for each hazardous chemical found
at the facility, as defined by the OSHA Hazard Communication
Standard.
2. A hazardous chemical inventory containing data on the quantity and
location of specified categories of hazardous chemicals.
3. Facilities within Standard Industrial Codes 20-39 are required to
report on releases into the environment of "toxic chemicals".
In addition, Title III provisions require the Governor of each State to
appoint a State emergency response commission to designate emergency planning
districts. Each district is responsible for developing an emergency response
plan (these plans are similar to preplans developed in the fire service) vhich
describes procedures to be followed should an emergency release occur.
1.4.2 State Programs
States must adopt environmental control programs as stringent as those of
EPA as a condition of program authorization or delegation under RCRA, CVA and
other relevant statutes. Some States have adopted requirements more stringent
than applicable Federal requirements. These programs may help POTW personnel
design or supplement POTV Slug Control Programs. For example, some States
have response teams or advisory personnel to assist localities in responding
to spills. California requires counties to prepare "Hazardous Vaste
Management Programs" to achieve "source reduction" for hazardous materials.
Each plan establishes market or regulatory-based incentives for industry to
reduce its generated quantities of hazardous waste (i.e., source reduction).
Industrial waste inspectors may help enforce plans through industry audits.
Other States may have contingency funds that can be activated to pay for the
initial cleanup costs before identification of a responsible party.
1-16

1.4.3 POTV Programs
Most POTVs have not developed formal programs specifically for slug con-
trol. Instead, many POTVs rely on issuance of industry-specific discharge
permits. Permit systems have the advantage of being able to include individual
slug control provisions tailored to the needs of a particular facility. These
provisions typically include special control, monitoring, and reporting
requirements.
A January 1987 AMSA membership survey on existing slug discharge control
programs shovs that while many major POTVs have instituted some degree of slug
discharge control, these controls vary in terms of approach and comprehensive-
ness (Table 1-4). For example:
• Vhile the vast majority (86 percent) of the POTVs define the term
"slug discharge" for regulatory purposes, POTVs indicated no clear
preference for either narrative or quantitative definitions
(Question 1). (See Table 2-6 for some example definitions.)
• Only one-half of the respondents specify minimum quantities of toxic
pollutants which would trigger notification requirements (Question 2).
• Nearly 3/4 of respondents restrict batch discharges, but less than
half of the respondents use either regulations, ordinances, or
policies defining concentrations, amounts or acceptable timing of
batch discharges (Question 3).
• Spills are regulated by nearly all respondents, (96 percent), and most
of these have ordinances/regulations requiring preventive, containment
or response measures. In addition, 84 percent of respondents require
the IU to notify the POTV of a spill (Question 4).
• Sixty-eight percent of respondents require spill prevention control
plans from Ills beyond those contemplated in Federal regulations
(Question 5).

2. PREVENTION OF IU SLUG LOADINGS
2.1 INTRODUCTION
The key elements to a successful Slug Control Program are: (1) IU slug
control plans and procedures for controlling batch discharges & spills, and
(2) procedures for the POTV to follow in IU permitting and enforcement and in
responding to IU slug loadings vhich escape prevention. This chapter dis-
cusses the three steps in developing and implementing a POTV Slug Control
Program:
• Evaluate the Need for a Slug Control Program (Section 2.2): Deter-
mine lUs and pollutants of concern, and potential risks associated
vith those sources.
• Develop an IU Control Program (Section 2.3): Evaluate or improve
legal authority to regulate lUs.Develop requirements (based on slug
potential) for designated lUs to develop slug control plans, and
inspect and monitor these sources.
• Implement the Slug Control Program (Section 2.4); Approve IU slug
control plans and monitor & inspect lUs for compliance vith the
plans. Develop and implement POTV slug response procedures.
Figure 2-1 outlines the organization of this chapter. First, ways to
identify high risk lUs and characterize the entire IU community are provided.
Methods to evaluate IU characteristics to determine slug potential and to
obtain and evaluate relevant information on slug potential are presented.
Second, technical guidance is provided on regulating potential slug
dischargers. The section describes controls that may be imposed on industrial
users to reduce the potential for slugs. Third, implementation of the Slug
Control Program is discussed. The fourth aspect of the Slug Control Program,
slug response, appears in Chapter 3.
2.2 EVALUATE THE NEED FOR A PROGRAM
While some POTVs already have Slug Control Programs in effect, others may
not simply because they have not yet experienced problems vith slug dis-
charges. Despite a lack of problems from slug loadings, development of a Slug
•Control Program may still be a good idea. Slug problems may arise in the
future, due to changes in IU practices, or as a result of spills. The need

for a slug control program also may be identified as a result of a toxicity
reduction evaluation (TRE). In addition, the Slug Control Program may help a
POTV comply vith whole effluent toxicity limits. The following subsections
describe how to determine whether new or revised Slug Control Programs may be
warranted.
In determining whether a POTV should adopt a new or revised Slug Control
Program, the POTV should assess:
• Vhether there are historical slug loading problems which need to be
addressed
• Vhich individual chemicals (stored or discharged) need to be
controlled, based upon potential to cause POTV problems, and for
chemicals to reach the POTV
• Vhich lUs, and ID practices, are actual or potential sources of slug
loadings
• Vhether existing programs or practices sufficiently address any
actual or potential threats.
2.2.1 POTV Definition of Slug
Because of site-specific variables, POTVs may wish to develop quantita-
tive or more specific qualitative definitions of the term "slug loading" to
supplement the definition in 40 CFR 403.5. Many POTVs have adopted fixed
quantitative definitions. Other POTVs prefer flexible, qualitative defini-
tions, especially for addressing mixtures of individual pollutants of concern.
A quantitative definition of what constitutes a "slug" should be consistent
vith local limits. For example, a POTV can use the PRELIM model local limits
•calculations to determine the concentrations of specific chemicals which would
cause POTV problems. A slug loading may be defined by the POTV as any amount
exceeding the local limits (in addition to the definition at 40 CFR 403.5). A
qualitative definition can be used as a complementary "catch all" should any
adverse impacts occur as a result of discharges at volumes or concentrations
less than those prescribed in the numeric local limits or for all chemicals
not addressed by local limits.
2-3
-------
Another way to define a slug loading is with reportable quantities (RQs)
as defined under Section 311 of the CVA and Section 102(b) of the Compre-
hensive Environmental Response, Compensation and Liability Act (CERCLA).
Whenever one of these substances is released into the environment in an amount
equal to or greater than the RQ, the release must be reported to the National
Response Center (NRC). RQs are assigned to each substance based on aquatic
and mammalian toxicity, ignitability, reactivity, chronic toxicity, and
carcinogenicity (for example, the RQ for aldrin is one pound whereas the RQ
for calcium chromate is 1,000 pounds, and an RQ of 5,000 pounds is assigned to
aluminum sulfate). A current list of RQs appears in Appendix B.
RQs are applicable to spills from Ills as they are to any facility. EPA
has proposed that certain releases from IDs to POTVs be exempt from NRC
reporting if they are "federally permitted releases", i.e., if the release is
(1) in compliance with applicable categorical pretreatment standards and local
limits developed in accordance with 40 CFR 403.5(c), and (2) discharged into a
POTV with an approved local pretreatment program or a 40 CFR 403.10(e) State-
administered local program [53 FR 27268, July 19, 1988].
Several POTVs have adopted RQs into their ordinances as the functional
definition of slug loading. Other POTVs have adopted the "reportable
quantities" concept, but have established their own quantities based on local,
site-specific concerns, such as previous problems associated with high
concentrations of certain pollutants in effluents or sludges, or problems
experienced in the treatment or collection systems. One POTV has adopted the
following quantities to protect its collection and treatment system:
• 10 Ibs. or more heavy metals (including arsenic, cadmium, chromium,
copper, lead, mercury, nickel, silver, zinc, cyanide) in solution
• 1 gallon or more of any toxic organic substances listed in the
Ordinance (which includes 46 base/neutral extractibles, 10 acid
extractibles, 28 volatile organics and 25 pesticides)
• All flammable liquids above 1 gallon
• 60 gallons or more of acidic solution (defined as pH less than 6.0)
• Any other liquid material determined to have adverse effects on the
sewerage system and wastewater treatment plants (including alkalies or
alkaline substances, oils, foam generating wastes, highly colored
wastes, pesticides and solvents not listed previously).
2-4
-------
Note that this POTV's ordinance provides quantitative definitions in some
instances, e.g., 10 Ibs of heavy metals, but allows regulation of other wastes
for which no quantitative limit has been set, e.g., "any other liquid material
determined to have adverse effects." This phrase provides the POTV vith the
opportunity to hold industrial users responsible for adverse impacts that may
result from slug loadings from other pollutants or mixtures of pollutants.
Three other examples that are fairly representative of those that appear in
many ordinances appear below:
• "...any waste discharge which, in concentration of any given con-
stituent or quantity of flow, exceeds four times the average 24-hour
concentration or flow during normal operation"
• "The discharge of water or wastewater from any IU into a public sewer
which results in any of the following conditions:
a surcharge higher than the crown of a normally constructed sewer
a volume more than five (5) times the maximum normal daily
discharge volume
a concentration which causes the user to violate maximum discharge
limi tations
an adverse effect on wastewater facilities"
• "Any discharge of water or wastewater concentration of any given
constituent or in quantity of flow for any period longer than fifteen
(15) minutes, more than five times the average twenty-four (24) hour
concentration or flow of normal operations of the user in question."
In developing a functional definition of slug loadings, POTWs should
concentrate on quantitative limits for those pollutants which are most likely
to cause adverse impacts. A list of classes of pollutants that may commonly
result in slug loadings appears in Table 2-1.
2.2.2 Identify Potential Sources
The next step in determining the need for a Slug Control Program is for
the POTV to identify whether any of its Ills has a history of, or the potential
for, slug loadings. The results from the IU survey conducted to identify
significant industrial users should be evaluated. After this, other infor-
mation from pretreatment program development can be used to identify and

characterize lUs for slug potential. Standard industrial classification (SIC)
codes may be useful for locating IU types which can be potential sources of
particular slugs (e.g., photo-processors).
Among industrial users that may occasionally discharge spent chemicals,
oils, solvents, and contaminated wastevater, and which merit inclusion in a
survey of slug discharge potential, are: major printing and publishing firms;
radiator shops; major automobile repair shops; industrial laundries; dry
cleaners; commercial pesticide and agriculture suppliers; railroad tank car
cleaning facilities (railroad yards); and commercial truck washing facilities.
Ills that store, but do not normally discharge toxic or otherwise hazardous
chemicals should also be briefly evaluated, even if they discharge relatively
small amounts of wastewater or only a sanitary wastewater discharge (so called
"dry" Ills). Examples of such facilities include the following: industrial
and commercial chemical warehouses; pesticide and lawn services; bulk oil and
fuel supply facilities; and paint and ink formulators. Sources of conven-
tional wastes that should be evaluated include: food processors, breweries,
meat packagers, and concentrated groups of restaurants discharging fats, oils
and greases. There may be other industries with intermittent or seasonal
batch discharges or a history of slug problems or surcharges that could result
in future slugs to the wastewater treatment systems.
The above discussion identifies industrial categories with slug poten-
tial. However, similar industrial operations may differ from plant-to-plant.
One industrial plant within a SIC category may pose a risk, and another of the
same type may not. Therefore, a plant by plant review may be necessary.
POTWs should consider the types and quantities of chemicals stored at each IU,
and the types of products and wastes generated to determine slug potential
(Table 2-1).
Existing Information
Records readily available to the POTW should be among the first evaluated
to determine potential risk of slug loadings. In addition to the industrial
waste survey conducted during pretreatment program development, the following
sources should or may be available to POTWs:
2-7
-------
t Baseline Monitoring Reports
• IU pretreatment permit applications
• Industrial user inspection reports
• Surcharge records
• Fire Department or other response agency records
• RCRA regulated facility lists or Superfund Amendments and Reauthoriza-
tion Act of 1986 (SARA) Title III, Community Right-to-Know data
• POTU effluent biomonitoring results and any information generated
under a TRE.
IDs may already have information which can be made available to the POTW.
Industrial users are generally avare that slugs can mean losses of raw
material, products, fuels, and production time, as well as liability for
damage to the POTV and the environment. POTVs will find some Ills may have
some form of slug loading control such as an inventory control plan. Although
the purpose of these plans might not be to protect the POTV or the environ-
ment, the plans can provide valuable information, and with some modifications
may form the basis of a slug control plan acceptable to the POTV. For
example, existing IU inventory control plans can be used to locate potential
problem processes or storage areas.
The POTV should also take note of any safety information from an IU as
industry personnel are likely to be well-informed about the dangers of
chemicals handled on-site. Fire departments that routinely inspect industrial
and commercial facilities to assess fire hazards or respond to emergencies
will also generally have records of emergency response calls or a listing of
chemicals utilized and stored at local industrial users.
Additionally, information may be available on the industrial and com-
mercial users regulated under RCRA and SARA. RCRA information is discussed in
Section 1.4.1. SARA'S Section 311 requires that facilities which must prepare
or have available material safety data sheets (MSDS) under OSHA regulations
must submit either copies of MSDS or a list of MSDS chemicals to the local
emergency planning committee, state emergency response commission and the
2-8
-------
local fire department. MSDS are made available to Il/s from manufacturers, and
include a listing of chemical constituents, precautions for product use, and
health effects data from exposure to the product. This information can be
used to help evaluate slug risk of lUs.
Collecting Additional Data
After reviewing all available information, POTWs also may choose to
gather additional information on IDs to supplement existing information, or to
independently verify any existing III information that appears questionable.
Information gathering should proceed in an organized fashion. Many POTWs may
have initially excluded lUs without process discharges from the original
industrial user survey. Even if the survey was comprehensive in its coverage
of all users, the effort may not have requested information on such items as:
• Storage and disposal of chemicals
• Existence of control or contingency plans
• Presence of floor drains in process areas
• Potential for accidental spills or other slug loadings
• Existence and adequacy of IU spill control or contingency plans.
If such gaps do exist in the original industrial survey, a follow-up of the
survey may be required. The POTV may choose to mail a survey to industrial
users similar to that which appears in Figure 2-2. Survey responses may then
be compared to existing information to fill data gaps and check for consis-
tency. Alternatively, POTWs may wish to require chemical storage inventories,
or other slug loading-related information on IU sewer permit application
forms.
In the first step, the POTV should request, (or require through ordinance
provisions, or as a permit condition), that certain information be provided to
the POTW to make an initial determination of slug potential. The second step
should be inspection of the facility. A POTW inspector can determine the
adequacy of the ILI's housekeeping practices, storage and containment
procedures, and general conditions to assess the Ill's slug potential.

The POTU may inspect lUs to independently verify both IU survey responses

existing inspection schedule, degree of confidence in previously provided
information, facility size, perceived slug potential, or any other related
factor. In preparing for these inspections, the inspector should review all
available information, familiarizing himself with the facility's operation and

• Data on Response Measures:
- Recommendations for equipment, structures, facility modifications,
and procedures for improving slug discharge prevention and response

2.2.3 Evaluate Existing Slug Controls: Legal Authority and Enforcement
As discussed earlier, the need for a new or revised Slug Control Program
often depends on the adequacy of existing controls. IDs may be self-motivated
to avoid slug loadings or other State or Federal requirements may have
resulted in adequate slug controls. But perhaps the most important factor in
determining whether existing controls are sufficient is the adequacy of the
POTW's own control program, especially its current legal and enforcement
authority. POTWs have often found it helpful to adopt a formal written Slug
Control Program outlining procedures for regulating slugs from IDs and for
POTW response to slugs which escape prevention at the IU source.
2.2.3.1 Legal Authority
All POTWs required to develop local pretreatment programs should possess
general legal and enforcement authority to deal with slug loadings. All POTU
programs should be consistent with 40 CFR Part 403, including:
• Compliance requirements with applicable pretreatment standards
including the general and specific prohibitions, categorical pre-
treatment standards, and locally developed limits
• Requirements for lUs to submit reports, including notice of slug
loadings under 40 CFR 403.12(f)
• Remedies for noncompliance by IDs.
Some POTWs may wish to add to existing legal authority to require installation
of IU slug control equipment and structures via their sewer use ordinance or
user permits. Samples of sewer use ordinance language addressing IU slug
discharge control requirements are presented below.
2-13
-------
Example Slug Control Clauses:
• Each User shall provide protection from slug discharges of restricted
materials or other substances regulated by this Ordinance. No User
who commences contribution to the sewerage system after the effective
date of this Ordinance shall be permitted to introduce pollutants into
the system until the need for slug discharge control plans or
procedures has been evaluated by the POTV. Facilities to prevent slug
discharges of restricted materials shall be provided and maintained at
the ovner and User's own cost and expense.
• Certain Users will be required to prepare Slug Discharge Prevention
and Contingency Plans (SDPC) showing facilities and operating
procedures to provide this protection. These Plans shall be submitted
to the Industrial Pretreatment Division (IPD) for review and approval.
All existing Users required to have SDPC Plans shall submit such a
Plan within three months and complete implementation within six
months. Review and approval of such Plans and operating procedures
shall not relieve the User from the responsibility to modify the
User's facility as necessary to meet the requirements of this
ordinance.
• In the case of a slug discharge, it is the responsibility of the User
to immediately notify the POTW of the incident. The notification
shall include location of discharge, type of waste, concentration and
volume, and corrective action.
Within five (5) days following a slug discharge, the User shall submit
a detailed written report describing the cause of the discharge and
the measures being taken by the User to prevent similar future
occurrences. Such notification shall not relieve the User of any
expense, loss, damage, or other liability which may be incurred as a
result of damage to the sewerage system, fish kills, or any other
damage to person or property, nor shall notification relieve the User
of any fines, civil penalties, or other liability which may be imposed
by the ordinance or other applicable law.
• A notice shall be permanently posted on the User's premises advising
employees whom to call in the event of a slug discharge. The User
shall ensure that all employees who may cause, or allow such slug
discharge to occur, are advised of the emergency notification
procedure.
2.2.3.2 Enforcement
POTVs must take appropriate action whenever a slug loading occurs. The
POTV should define its enforcement strategy and range of appropriate actions
to be taken in cases of slug loading violations. The strategy must provide
immediate and consistent response to slug loadings which cause violations of
prohibitions and to lUs who fail to notify the appropriate authorities of a
2-14
-------
slug loading. To formulate this enforcement strategy, the POTW should first
identify the types of non-compliance which may arise under its particular Slug
Control Program. These may include: (1) failure to implement required con-
trol measures to prevent slug loadings; (2) failure to prepare or submit
industrial user slug control plans on time; (3) failure to implement indus-
trial user slug control plan provisions (e.g., acquiring equipment, providing
training, altering facilities etc.); (4) failure to immediately report slugs
under 40 CFR 403.12(f); (5) failure to submit detailed follow-up reports; and
(6) submittal of fraudulent information.
The POTW should then determine its potential enforcement responses should
non-compliance occur. These options may be formal or informal actions
including, for example: (1) telephone calls or meetings; (2) warning letters;
(3) notices to show cause; (4) administrative fines or orders; (5) permit
suspension, revocation or modification; (6) civil suits; (7) criminal actions;
and (8) termination of service. The type of enforcement response may depend
on the severity of the violation, the violator's history of noncompliance, the
length of time the violation continues, and the violator's "good faith"
actions to mitigate damage or return to compliance. Generally, the POTW
should rely on the same enforcement strategy it employs to obtain compliance
with effluent limits or other Pretreatment Standards. EPA's Pretreatment Com-
pliance Monitoring and Enforcement Guidance identifies the factors to consider
when developing enforcement strategies and for determining the appropriate
enforcement response.
2.3 DEVELOP AN IU CONTROL PROGRAM
The most important part of the Slug Control Program is the requirements
that the POTV imposes upon its IDs. After the POTW determines for its own
program any additions to the regulatory slug definition (40 CFR 403.5),
evaluates the entire industrial user community for slug potential and
identifies the need for a Slug Control Program, the POTW can then determine
what will be required from each IU. As part of this evaluation, the POTW
should consider the adequacy of existing IU slug controls, both as written
and, more importantly, as implemented.
2-15
-------
Vhile the POTU may choose to subject sources to varying levels of control
dependent on the slug "risk" they pose, the requirement for IDs to inform the
POTV of a slug or changed conditions affecting slug risk potential should
apply to all IDs. All IDs should also be made aware of the POTV's right to
inspect the industrial user, reevaluate slug risk classification, and to
impose more stringent slug control requirements as necessary.
2.3.1 Mandatory Notification Requirements
Currently, 40 CFR 403.12 (f) requires all IDs to immediately notify the
POTV of any slug loading. This requirement should be made known to all indus-
trial users. EPA suggests that IU permits and/or municipal ordinances
prescribe slug notification requirements as follows:
• Procedures to inform the POTU of slug loadings, including requirements
for posted notices of appropriate POTV contact names and phone numbers
• The substantive information to be provided, such as nature of contami-
nants released, quantities of contaminants, any response action taken
• Post-discharge reporting requirements such as follow-up reports and
documentation of the events and its causes and effects
• Changed in-plant conditions affecting slug risk potential.
lUs should be required in the event of fire or explosion hazards to
immediately notify the appropriate local agencies, such as the fire depart-
ment, in addition to the POTV. If required, local, State and Federal agencies
should also be made aware of slugs (i.e., SARA Title III reporting require-
ments). The POTV contacts and phone numbers should be clearly posted for all
workers. Some POTVs provide names of alternate contact persons or install a
24-hour hotline for use in reporting slugs.
Ills should provide the following information upon the occurrence of a
slug loading (a sample POTV notification log sheet is provided in Appendix C):
• Date and time of the discharge
• Discharge location
• Concentration, volume, waste type, chemical name, and harmful charac-
teristics or effects of the material (e.g. explosive, flammable)
2-16
-------
• Response measures being taken
t Other agencies or contractors contacted.
Post-Discharge Reporting Requirements
Within five days after the slug the III should prepare a vritten report.
(A sample report sheet appears in Appendix C.) The items that should be
discussed in the follow-up report include:
• Cause of the incident
• Specific details of the incident (time, volume and concentration of
pollutants released, damage, etc.)
• Remedial measures undertaken
• Preventive mechanisms to avoid a recurrence of similar incidents
• Other information as required by POTtf's spill response system.
The POTV should use this report to evaluate the effectiveness of the Ill's slug
prevention and response capabilities, and to determine the need for revising
the Ill's slug control plan.
2.3.2 Slug Loadings from Batch Operations
Slug loadings from batch operations may harm the treatment plant, its
workers, and/or the environment. Regular discharges from batch operations
that could result in slug loadings should be regulated via IU sewer use
permits or other similar control mechanisms. Ills can be required to equalize
flows, neutralize pH, or take other appropriate steps to ensure that batch
discharges do not result in slug loadings. Several POTVs have found that
prior notice of a batch discharge by an III, including the constituent concen-
trations of those discharges, can allow POTV influent flow equalization, or
other special treatment, and can prevent damage from batch operation slug
loadings. High risk lUs can be required to notify the POTW in advance of an
irregular batch discharge and to keep records of the discharge.
For example, the POTU may require the IU to contact the Water Quality Lab
supervisor at least one week before discharging wastes from its batch process
2-17
-------
tanks which could result in a slug loading, as determined by the POTV. The IU
is then required to satisfy all pretreatment requirements of its permit, such
as neutralization of the wastewater to meet permitted pH, and to sample and
analyze the process tank(s) for all parameters items listed in the permit.
Lab results are forwarded to the Water Quality Lab Supervisor for review. If
the pollutants are within allowable ranges, and the lab results demonstrate
that pretreatment requirements are satisfied, the POTW approves the batch
discharge request. This approval procedure is documented on a form which is
signed and dated by the discharger and the POTV representative.
Some batch discharges are routine. For example, pH swings can result
from regular cleaning operations. Requirements that may be appropriate for
routine batch discharges include:
o Use of continuous pH and temperature monitoring with recording tapes
while discharging
o Specific allowable discharge times, i.e. during POTU operator shift,
or at time of maximum daily flow
o Notification by phone followed by a letter anj analytical report
o IU retention of records regarding all batch discharges.
These approaches are most useful for lUs with consistent wastes which have
been characterized by routine POTV and IU monitoring. lUs with a highly
variable pollutant loading in the wastes to be discharged, or industries thac
are not part of a routine monitoring and inspection program, should be
regulated more stringently.
Another aspect of the program should address lUs not covered by pre-
treatment permits. In some instances, nonpermittees whose discharge could
contain industrial waste, or wastes from spill or ground-water cleanup
operations (or other nonroutine discharge events), may request permission to
dispose of a batch discharge. The POTV should determine whether to accept the
waste depending on the potential for interference or pass through of the
discharge. Sampling and inspections of all lUs, even those not currently
regulated via a sewer use permit or similar mechanism, may be appropriate.
2-18
-------
2.3.3 Assign Ills to Slug Risk Categories
POTUs may choose to adopt varying levels of control on lUs based on the
slug risk potential they pose (see Table 2-2). The determination of the risk
posed by any single facility can be evaluated by looking at many different
factors. The most important factors in determining the ID'S slug load risk
potential are:
• The quantity and types of materials used or stored at an IU
and their potential for causing violation of local limits or the
general or specific prohibitions
• The potential for such materials to enter the sewer system and cause
damage (i.e., whether control measures are in place)
• The adequacy of existing controls to prevent any potential slug
loading.
Potential to cause harm may be based upon knowledge of previous slug
impacts, local limits calculation, or other means. Many POTVs have developed
different IU categories, and associated regulatory requirements, for each risk
category (i.e., high risk, medium risk and lov risk facilities). Industrial
users may be re-assigned to higher or lower risk categories if IU practices
change. For example, if a POTV learns of a slug discharge, new operating
procedures or other changes at an IU which could affect slug potential, that
IU may be reassigned to a different risk category.
Risk categories may be based on quantitative or qualitative criteria.
Risk categories based on quantitative criteria include, for example:
• Significant industrial users
• lUs discharging greater than 25,000 gallons or more per average work
day
• Specific SIC codes using RCRA-listed or characteristic hazardous
materials
• Each discharger who stores 1,000 gallons or more of liquid substances
identified in the POTW's sewer use Ordinance or in Section 311 of the
CWA.

-------
Other qualitative criteria may include any discharge of RCRA hazardous wastes
or past slug loading problems.
Another approach that may serve to supplement, or supplant, the use of
objective criteria is the use of subjective criteria associated with risk.
For example, a POTW may require "designated Ills" to implement comprehensive
slug control and prevention plans. "Designated Ills" could be those Ills "whose
wastewaters include, or could include, pollutants capable of causing inter-
ference. This includes all categoricals, and those lUs found by the POTV,
State or EPA to, singly or in combination, have a significant impact on the
treatment system, sludge quality, effluent quality, or air emissions."
Alternatively, facilities may be categorized as "low", "medium" or "high"
risk. Table 2-2 summarizes the characteristics of each risk category.
Low-Risk Facilities
• Low risk IDs may receive this designation due to a lack of sewer
connection, handling practices, presence of control devices, or
absence of potentially harmful levels of toxic or hazardous materials.
• No slug controls are necessary because these Ills present little risk
of discharging slugs in quantities/concentrations capable of adversely
affecting the POTV, its workers, or the environment.
* The IU should be notified of its low-risk classification, and required
to notify the POTW if the plant conditions change.
Medium-Risk Facilities
• Medium risk lUs may use or store less than harmful quantities of toxic
or hazardous materials of concern, and need to take some corrective
measures to prevent spills or regulate batch discharges of materials
which, if discharged as a slug, would create a problem. These lUs can
be assumed to have some direct connections (floor drains included) to
the POTV collection system.
• The IU should be required to undertake specific preventive measures.
For example:
Protect floor drains from spills and eliminate cross connections
Improve housekeeping practices
Construct diversionary berms
2-21
-------
Post signs advising employees not to dump material down the drain
- Modify existing storage and handling of chemicals and hazardous
waste
Conduct preventive maintenance on valves and piping
- Employee training program
Maintain in-house pretreatment, diversion, or containment
capabili ty.
• The POTV should notify the IU of its medium-risk classification, and
be required to notify the POTW if plant conditions change so the
classification can be changed to low or high risk..
High-Risk Facilities
• High-risk facilities include IDs classified as significant under the
POTV pretreatment program, plus additional facilities discovered
through the POTU Slug Control Program evaluation process. Such
facilities use, store or discharge at or above significant quantities
of constituents of concern (e.g., the RQs) or have a history of slug
loadings, and present a high risk of discharging materials known from
experience or local limits, etc. to cause interference or pass
through.
• High-Risk Facilities facilities should be required to develop and
implement a facility-specific Slug Discharge and Prevention
Contingency Plan. The lUs pretreatment permit or other type of
control agreement should include:
Details of the specific requirements for development of a Slug
Control plan
A schedule for submittal to the POTV for approval
A requirement for the ID to implement the plan once approved by the
POTV.
• The IU should be notified of its high-risk classification and required
to notify the POTV if plant conditions and risk decrease.
The process of classifying facilities into risk categories may be
simplified by using a slug potential data form. Tables 2-3 and 2-4 are
examples of slug potential data sheets containing summary information for
conventional waste dischargers (Table 2-3} and lUs that store, use, or
discharge materials of concern to the POTV which could result in slug loading^
(Table 2-4). POTVs can adapt these forms foi "•.nmarizing It) and inspection

data. The quantities included in Tables 2-3 and 2-4 are provided in units of
volume (gallons) rather than weight (pounds). Volume data may be more useful
than mass loading data when responding to spill situations.*
For facilities capable of discharging high-strength conventional wastes
of concern, the POTV should list the type of conventional wastes and describe
the industry's type of discharge (batch, continuous), industry operation
(seasonal, yearly), and normal production figures (Table 2-3).
A POTV hazard classification system can be used to indicate hazards
associated with a slug of,each chemical at a facility and can provide valuable
information concerning appropriate control and cleanup techniques. POTW
hazard classification information should be based upon the expected impact of
a slug loading of a chemical or material upon the POTV. MSDSs or the National
Fire Protection Association (NFPA) Classification Scheme can be used to help
determine the POTV hazard. The POTV should evaluate the MSDS information and
NFPA classifications to determine the applicability for slug control.
If necessary, the POTV should seek the assistance of industry personnel
and the local fire department in identifying IU sources and quantities and
classifying chemicals by hazard code. IU representatives should have the
MSDSs for many chemicals. The POTV inspector should also note all RCRA-listed
or characteristic hazardous wastes that may be stored at the ID prior to
disposal, such as pretreatment sludges.
EPA recommends that POTVs summarize all of the IU data provided by the
industrial users or obtained during inspections. Data storage and retrieval

will aid in evaluating slug loading potential and tracking and identifying
slug sources. This summary data can be stored in a computer database or a
summary data table such as the one presented in Table 2-5. The data storage
and retrieval system should incorporate:
• A list of all industries within the POTW's jurisdiction.
• The Sewer Service Area for each facility. Industries may be assigned
a sewer service area number based on geographic location. When a slug
occurs in a specific area, the POTV can identify industries dis-
charging to that location.
• Chemical hazard classifications (from Table 2-4 or 2-5) applicable to
each facility
• Major materials of concern stored, used, or produced at the facility
• Regular batch discharge schedule
• Potential for spills
• Classification of slug risk
• Status of lU-specific Slug Control Plan
• Comments/observations.
In the event of a slug, Table 2-5 helps POTV staff quickly locate the source
of a slug based on chemicals of concern and sewer service area. The POTW can .
then refer to the ID-specific slug potential data sheets (Tables 2-3 and 2-4)
to obtain more detailed information. Efficient data collection and retrieval
can facilitate slug identification procedures, thus accelerating response time
and reducing the damages incurred by each incident.
2.3.4 Requirements of IU Slug Control Plans
This section outlines the recommended contents of an IU Slug Control
Plan. As discussed in Section 2.3,1, notification requirements apply to all
dischargers. In addition, POTWs should select fron among the control measures
described in this section and require medium- and high-risk facilities to
implement appropriate control measures. POTWs may also require high-risk
facilities to develop IU Slug Control Plan?, vhere necessary. Flans should be
reviewed by the IU on a regular basis or vhen changes in design, construction.

operation, and maintenance at the facility warrant modification. A schedule
for plan review and procedures for plan modification should also be described
in the Plan. The Plan should also be reviewed when new conditions require
changes in the emergency response procedures and any time a slug has occurred.
The general elements of ID Slug Control Plans are as follows:
• GENERAL INFORMATION: It) Name and Address, IU Contact, Discharge
Practices, Security Provisions and Employee Training (Section 2.3.4.1)
• FACILITY LAYOUT FLOW DIAGRAMS: General layout including mapping of
manufacturing, storage, transportation, and disposal areas
(Section 2.3.A.2)
• MATERIAL INVENTORY: Types, volumes, containers, etc.
(Section 2.3.4.3)
• SPILL AND LEAK PREVENTION EQUIPMENT AND OPERATIONS AND MAINTENANCE
PROCEDURES: Definition of available equipment, plans to obtain
equipment (Section 2.3.4.4)
• EMERGENCY RESPONSE EQUIPMENT AND PROCEDURES: Inventory and location
of equipment; and procedures (Section 2.3.4.5)
• SLUG REPORTING: Description of procedures for notifying POTV
(Section 2.3.4.6)
• TRAINING PROGRAM: Assurances that the Plan is implemented by pro-
viding for employee training (Section 2.3.4.7)
• CERTIFICATION: A certification by a professional that the Plan is
adequate to prevent and control slugs (Section 2.3.4.8).
Two sample plans appear in Appendix D.
2.3.4.1 General Information
An IU Slug Control Placr must include sufficient general information to
enable the POTV to: (1) categorize and restrict the lU's potential for a slug
discharge; and (2) respond promptly and effectively in an emergency. General
information should include a brief description of the IU, discharge practices,
applicable pretreatment standards, and description of previous slugs and
corrective actions. The information requested in the Industrial User Slug
Potential Survey (Figure 2-2) is an outline of rhe kinds of information
generally required in this element of a Slug Control Plan.
2-30
-------
2.3.4.2 Facility Layout Flow Diagrams
Each Plan should include detailed drawings of the facility shoving the
following:
• General layout of the facility
• Areas occupied by manufacturing or commercial activities; property
boundaries, drainage of rainwater, and connections to the city's
sanitary sewer and storm drains
« Hazardous materials process and storage areas; waste handling,
stoiage, and treatment facilities
• Loading and unloading areas
• Direction of drainage from hazardous materials and waste handling,
process, storage, and treatment areas
t Floor drains, pipes, and channels which lead away from potential leak
or spill areas [identify by coding footnotes, or narratives describing
drainage patterns]
• Flow diagram(s) showing chemical and wastewater flow including piping
and instrumentation, flow rates, tanks and capacfties, treatment
systems, and final destinations of flows.
2.3.4.3 Material Inventory
The facility should provide sufficient data on all materials of concern
used and stored at the facility. This may include those materials for which
the POTW has established local limits (see Section 2.2.1). This information
is useful in determining the origin of a slug, potential hazards and appro-
priate slug response procedures. Descriptions of the material handled, the
location of these materials, descriptions of containment, transfer and
transport, as well as any additional comments should be provided as follows:
• Materials - Both chemical and trade names should be listed in the
inventory (OSHA MSDSs may be used). This information may help
minimize confusion over the constituents of a compound and facilitate
proper response procedures to a slug.
• Location in Plant - Knowing the location of (RQ) materials will assist
plant employees and emergency response personnel in locating areas
initially affected by a spill.
• Maximum Volume/Container Volume - This information is useful in
determining the potential impact of a slug.
2-31
-------
• Container Description - The description should include the type of
container (e.g., steel drum, fiberglass tank, etc.) and the presence
of container attachments such as valves, pumps, transfer pipes, etc.
The description of a container will help determine potential origins
of a slug load.
• Transfer and Transport Areas - The condition of containers and
transfer equipment is useful in assessing the potential for accidental
spills or slug discharges of high strength wastes and possible effects
on the treatment plant.
• Additional Comments - Additional comments should include information
on the physical, chemical, and toxicological effects of each material,
and special precautions that should be taken when handling these
materials. A discussion should also be provided on the procedures to
prevent contact between incompatible materials. Each facility must
demonstrate that the following three compatibility aspects have been
considered: (1) the construction of the container; (2) other mate-
rials in the immediate vicinity; and (3) the surrounding environment.
2.3.4.4 Spill and Leak Prevention Equipment and Procedures
This subsection is divided into a discussion of equipment and procedures.
It provides information on the data an IU Slug Control Plan could contain. It
also provides technical information that may be used to evaluate the adequacy
of the equipment and procedures detailed in an IU Plan. The POTV's review and
evaluation of the IU Plans should use, but not be limited to the information
provided here. Additional references, including those listed in Appendix E,
should be reviewed and a thorough understanding of the IU operations should be
achieved prior to evaluating the IU Plan.
Existing and Proposed Spill Prevention and Containment Equipment
Equipment required to control spills falls into two categories:
• Equipment to prevent spills
• Equipment to contain spills.
This section of the lU's Slug Control Plan should identify all existing
equipment and/or systems that the IU nas in place or plans to obtain to imple-
ment the Plan. If equipment needs to be purchased, the expected purchase
dates should be provided.
2-32
-------
The Plan should describe current and projected inventories of both types
of equipment. Equipment to prevent spills consists of appropriately selected
chemical storage and process equipment, as well as built-in safeguards to
prevent chemicals from being spilled such as secondary containment structures.
Spill containment equipment consists of equipment or apparatus to keep a spill
from spreading and to remove the spill. Examples of prevention and con-
tainment equipment are listed below:
• Equipment to Prevent or Detect Spills
Chemical Storage and Process Tanks: holding tanks, pumping
equipment (compatible material); shell and bottom construction
(compatible material); underground seepage protection; cathodic
protection of underground tanks; liquid level sensing devices;
overflow, temperature, pressure alarms; heating coils; collision
protection support construction; secondary containment; diver-
sionary structures in quench tanks
- Drums: drum construction; storage areas; secondary containment;
diversionary structures; collision protection; drum handling
equipment; drip pans
Pipes, Valves, Fittings, Pumps, Electrical and Mechanical
Equipment:seals;valve stem packing; gaskets;cathodic protec-
¥
il\
tion; vehicular traffic warning signs
Loading Stations: fill safeguards; curbs and drains; warning
signs/improper disconnect protection; secondary containment
Alarm Systems: to detect unauthorized discharge flows, pH
excursions,etc.
• Equipment to Contain Spills: booms, barriers, sweeps, and fenders;
surface collecting agents; absorbent materials; skimmers; oil/water
separators; sumps; sewer plugs.
Once spill potential reduction measures have been addressed, secondary
containment systems should be considered. An IU which has the potential for a
slug discharge should provide secondary containment systems, wherever
possible, that will control the spread of a spill of toxic wastes or slug
discharges of high-strength wastes at or near a potential spill source (e.g.,
storage tanks, processing equipment and piping). Several forms of secondary
containment systems may be used including diking, diversion, holding tanks, or
quick drainage. These methods are described belov.
2-33
-------
Diking is the most effective form of secondary containment for bulk
chemical storage. Dikes can be constructed from concrete, cinder blocks, or
earth. Bulk storage tanks and/or drum storage should be surrounded vith an
impervious dike that will hydrostatically contain 110 percent of the capacity
of the largest tank or the capacity of the largest tank plus water from a
maximum 24 hour/10 year rainfall event, whichever is greater. Accumulated
rainwater from diked areas should be drained with a manually operated pump or
siphon system. If a valve pipe has been installed through the dike wall, the
drainage valve should be kept locked in the closed position when not in use.
Flapper valves should not be used.
Design of the dike should account for the containment of a spraying leak
from the side of the tank. Where this design is not feasible, baffles could
be installed at the top of the dike that would deflect potential leaks and
cause them to drop within the containment area.
Diversion of flow of potentially spilled material away from its naturally
expected path can also be an effective means of secondary containment.
Diversionary structures consist of curbs, sumps, and/or gutters which divert
spilled material to a collection tank. A quick drainage system is frequently
employed in small volume storage and loading areas. It consists of an
impervious curbed or below gradient pad that slopes into a drain that is
connected to an impervious sump. Spilled volumes of liquid are collected in
the impervious sump and then removed and appropriately treated, discharged, or
disposed of. These structures should be used in areas where diking is
impractical or unsafe.
For example, chemicals which emit noxious fumes might be diverted to a
closed tank in the event of a spill, rather than left in an open diked area.
Diversionary structures can include quench tanks, which serve to simul-
taneously collect and treat chemicals. Many industrial facilities possess
process quench tanks to control runaway chemical reactions.
Procedures
The operation and maintenance procedures designed to minimize spills ar
a facility are as important as the selection and installation of the
2-34
-------
equipment. Many operation and maintenance procedures are common-sense,
however, and should be adequately included in every Plan. For example, incom-
patibility of materials vith the container can result in leaks or explosion of
the container. Elements of good housekeeping include neat and orderly storage
of chemicals and prompt cleanup of spilled liquids or powders to prevent them
from reaching the sever collection system. An effective preventive mainte-
nance should include periodic inspections and testing of equipment systems,
appropriate adjustment, repair, or replacement of valves and other parts.
Also, a security system to prevent accidental or intentional entry to the IU
site vould reduce the risk of vandalism, theft, sabotage, or other illegal use
of the plant facility that could possibly cause a slug loading.
Simple operating and maintenance procedures directed at eliminating
spills and leaks include, but are not limited to, the following:
• Inspect All Chemical Storage Vessels, as Veil as All Process Vessels
and Fittings (Pumps, Valves, Piping):The items must be constructed
of material compatible with the chemicals passing through them. In
particular, tanks and drums used to store corrosive chemicals should
be constructed of stainless steel or of a corrosion resistant plastic.
The plan should discuss all routine operation and maintenance
(including housekeeping and replacement of worn-out equipment)
performed to minimize spills. The frequency of inspections and
monitoring for leaks or other conditions that could lead to spills
should also be indicated. Any pumps or valves used to process these
chemicals must possess corrosion-resistant seals and packings.
Similarly, pumps or valves through which organic chemicals pass must
contain seals and packings which are dissolution-resistant. The ID
should indicate in its Plan that appropriate materials of construction
have been used, and are compatible with the chemicals being processed.
• Inspect Foundations and Supports of Large Storage Tanks, Process
Vessels, and Piping.These must also meet compatibility and integrity
requirements:All above ground vessels should be protected from
vehicular damage through the use of truck guards. Underground vessels
and pipes should be well marked and weight limits placed on roadways
that may cross these underground vessels. All underground vessels
should be cathodicly protected to prevent damage due to corrosion.
Underground piping should be double-walled at vehicle crossings.
• Equip Open Storage and Process Tanks vith Liquid Level Control
Devices, and Grounding Apparatus (where necessary): In addition,
overflow alarms should be installed to warn personnel of tank over-
filling. Similarly, temperature and pressure alarms should be
installed on closed chemical processing equipment, to alert industry
personnel to runaway reactions or other factors resulting in excessive
2-35
-------
temperatures and pressures. Such extreme conditions can otherwise
result in the automatic opening of relief valves, subsequently
spilling the process vessel's contents.
• Use Proper Drum Handling Equipment: The practice of scooping drums
with the forks of a forktruck should be eliminated. Pallets should be
used to aid handling and inspection. Oil dispensing racks should be
provided with drip pans.
• Secure Loading/Unloading Pump Station Controls; In a manner to
prevent the pumps from being turned on by unauthorized personnel.
Warning signs or physical obstructions, such as crossing gates, should
be used to prevent trucks from driving away while the loading hose is
connected.
• Eliminate All Unnecessary Cross Connections: All unnecessary floor
drains should be plugged,especially those in high-risk areas.
• Utilize Automatic Stormwater and/or Sever Sampling Systems to Monitor
for Spills;These sampling systems can be tied into automatic shutoff
devices that will prohibit discharge from a plant effluent system.
2.3.A.5 Emergency Response Equipment and Procedures
Equipment
Information that should appear in this section of the IU Plan includes an
inventory of available IU emergency response equipment and a detailed descrip-
tion of emergency response procedures. The emergency response equipment
inventory should also contain the equipment location on the facility layout
diagram and a physical description of each piece of equipment. A summary of
the information that should appear in this part of the plan follows:
» Communication Equipment and Alarms; A communication system should be
establishedfor reporting emergencies and providing immediate emerg-
ency instruction to facility personnel vith the use of a telephone.
intercom, radio, alarm, etc.
• Spill Containment and Control Equipment and Tools: Examples of this
type of equipmentinclude sorbent materials and dry chemicals which
are often used for containing spills of small volumes.
• Spilled Material Storage Containers: Chemical spills must be con-
tained and removed as soon as possible to prevent materials from
spreading into other areas.
• Protective Clothing and Respirator:?: In responding to an emergency
hazardous spill, employees should take precaution to ensure that as
2-36
-------
much skin is covered as possible. Flameproof protective clothing vill
not only prevent chemical burns, but vill also protect skin during a
fire. Other examples of protective clothing include:
Rubber Gloves
Apron
Goggles/Face Mask
- Hard Hat.
In addition, depending on the nature of the emergency, the use of
self-contained breathing apparatus may be necessary. All employees
involved in response procedures should have access to the breathing
apparatus and be adequately trained in the use of this equipment.
• First Aid Kits: A well equipped first aid kit should be immediately
available for use if necessary. The plan should indicate the location
of the kit, and the items that it'contains. Items that are essential
to a first aid kit include: antiseptic solutions and bandages for
application of wounds; artificial respiration devices, and eyewashing
solutions and cups.
• Ventilation Equipment: Before entering an area where a potentially
explosive spill has occurred, tests should be made for explosive
atmosphere, the presence of toxic gases and oxygen deficiency.
Whenever an adverse atmosphere is encountered, forced ventilation,
such as powered explosion-proof ventilators, blowers, or fans, can be
used to create safe conditions. Ventilation should be continued as
long as recurrence of the hazard is possible.
• Decontamination Equipment: The appropriate protective clothing and
monitoring equipment should be used in responding to a spill of
radioactive material.
• Fire Extinguishing Systems: A list of fire extinguishers and their
locations should be posted throughout the plant. In addition, a map
that shows both fire extinguisher location and fire hose connections
should be submitted to local response agencies.
Procedures
Each IU Plan should contain a detailed description of procedures to be
followed in responding to a hazardous spill at the facility. The established
procedures should be designed to eliminate danger to human health and to
facilitate containment and clean-up of a spill. A description of the pro-
cedures should contain the following items: notification of responsible
personnel, chain of command, evacuation procedures, notification of response
agencies, and spill assessment and response procedures. A fuller description
of each of these elements follows:
2-37
-------
Notification of Facility Personnel Responsible for Responding to
Spills:Each facility should have a person(s) who is qualified to
respond to a spill at the facility. There should be at least one
person available at all times to carry out appropriate response
procedures. This person(s) should be familiar with all aspects of the
Plan and have the authority to commit the resources necessary to
initiate emergency response procedures. All Employees should be aware
of which person(s) to contact if a spill takes place. It is recom-
mended that a sign indicating who to contact and the appropriate phone
number(s) be posted in all areas where a spill may occur.
Chain-of-Command: Proper chain-of-command procedures should be
followed when responding to an accidental spill or slug to ensure that
all necessary personnel and response agencies are notified. A
description of these procedures should be included in the Plan.
Evacuation Procedures: An evacuation plan should be posted throughout
the facility and discussed in safety training sessions. The plan
should contain: (1) a map of evacuation routes; (2) a map of alterna-
tive evacuation routes; and (3) a description of signals used to begin
and conduct an evacuation. A copy of the evacuation plan should be
submitted to the local police department; fire department; and
hospitals for their records.
Notification of Response Agencies and Contractorst A list of spill
response agencies and their numbers should be available to each
employee assigned to coordinate spill response activities. In the
event of potential or actual emergency situations, the appropriate
response agency should be notified immediately.
Spill Assessment and Response Procedures! The person(s) designated to
carry out spill response procedures should begin by assessing the
spill. A determination should be made on the origin of the spill and
what impact the spill will have. Based on this assessment, the
coordinator will initiate proper response procedures. Spill response
procedures that should be included in the plan include:
Notification of facility personnel by activating the communication
and/or alarm system
Begin evacuation procedures if necessary
Notification of appropriate local, State, and Federal agencies^
Stop the flow by shutting off pumps or closing valves
Prevent contact between incompatible materials
Commence clean up activities
Submit necessary reports.
Procedures for Clean-up, Treatment, and 01 Disposal of Spilled
Materials: Once a spill has been contained, clean-up of the waste
2-38
-------
material begins. The material should be immediately treated or
disposed of to eliminate health and safety hazards and to prevent the
dispersion of the material. The objectives of treating the material
prior to disposal are to reduce the potential impact of the waste on
vater quality and to recover valuable materials. Several methods of
disposal are available, however, the facility should choose the proper
method based on the nature of the material. If waste generated from a
spill is determined to be hazardous, the facility must meet RCRA
requirements. Information pertaining to treatment and disposal
methods used by the facility should be included in the Plan.
In addition, if it is anticipated that outside contractors and/or
consultants may be utilized in clean-up, treatment, or disposal
methods, the plan should include the name of the company; contact
person and phone number; and the available equipment and manpower
necessary for the job, if possible.
These procedures should be consistent with the ones established in the
facility's OSHA Emergency Action Plan, as required by 29 CFR §1910.38.
2.3.4.6 Slug Reporting
Procedures for reporting and documenting spills and,slug discharges
should be described in the Plan. At a minimum, the IU follow-up report should
include: (1) the time, date, and cause of the incident; (2) the impact of the
spill on the POTW and the environment; (3) extent of injury and/or damage; and
(4) how other incidents of this type can be avoided in the future. A descrip-
tion of clean-up, treatment, and disposal procedures must be included where
applicable. The report should also evaluate the adequacy of the Ill's response
procedures. In particular, the investigator's reports should address the
following questions:
• Vas the safety of industry personnel and the surrounding community
ensured throughout the incident?
• Were personnel working close to the incident provided adequate access
to breathing .apparatus, protective clothing, etc.?
• Was the spill confined quickly?
• Was fire extinguishing equipment adequate and readily available when
needed?
2-39
-------
• Did secondary containment structures remain intact throughout the
spill response? Uere these structures of adequate volume to confine
the spill or slug discharge?
• Were appropriate POTU, fire department, or other officials immediately
notified of the incident?
Recommendations for improving operational, inspection, maintenance,
and/or spill response procedures based upon the incident should be included.
The investigation report should then be made available to the POTU, fire
department, and insurance firms if applicable, to assist these agencies in
their own investigations. In addition to reporting procedures, copies of
forms used for reporting and a list of appropriate response agencies and phone
numbers should be incorporated into the Plan.
2.3.4.7 Training Program
More important than establishing the IU Slug Control Plan is the effec-
tive implementation of that plan by IK employees. The Ill's Plan should
contain an outline of the training program given to employees. An employee
training program can provide employees at all levels of responsibility with a
complete understanding of the processes and materials used, the safety
hazards, the practices for preventing discharges, and the procedures for
responding properly and rapidly to hazardous materials spills and slugs.
Specialized training should also be provided to each employee or group of
employees that handle potentially hazardous chemicals.
Periodic training sessions are essential and should be conducted at
appropriate intervals to assure complete understanding of the lU's Plan, goals
and objectives. New employees should be trained immediately upon employment.
Employees should also be notified and retrained when their responsibilities or
functions under the plan change. Training records should be maintained by the
plant manager as long as a person is employed at the facility and for at least
three years from the date the employee last worked at the facility. Periodic
drills should be instituted to evaluate employee knowledge and understanding
of the Plan. The purpose and frequency of such drills should be indicated in
the Plan. Training to implement the OSHA-required Emergency Action Plan
should also be coordinated with the Plan '.raining, especially •..'hen the
2-40
-------
procedures and responsibilities are uniform. To Che extent the procedures
differ, Emergency Action Plan training should be conducted periodically as
veil to ensure worker safety in the event of a slug or any other emergency.
2.3.A.8 Certification
A qualified professional should certify the adequacy of the measures
described in the Plan. Table 2-6 shows an example of what this certification
should include.
2.4 IMPLEMENT THE PROGRAM
Upon completion of the development of a Slug Control Program, including
the identification of the IU community, development of appropriate legal/
enforcement authority, assignment of risk categories and controls to address
those risks, the program should be implemented. There are three activities in
the implementation of a Slug Control Program:
• The review and approval process of ID Plans (Section 2.4.1)
• An IU inspection and monitoring program (Section 2.4.2)
• POTV Slug Response (Chapter 3).
POTWs may find it useful to develop a Procedures Manual to provide a
written record of the POTV's Slug Control Program. It should address all
aspects of the POTWs Program in summary form, including review of ID Plans,
POTV inspection and monitoring of lUs, and slug response procedures.
2.4.1 POTV Review and Approval of IU Slug Control Plans
EPA recommends that POTWs review the Plan of all applicable industrial
facilities to ensure that all pertinent slug discharge control issues are
addressed. Appendix B includes a review checklist which can aid the POTV in
reviewing the IU implementation of required procedures.
The IU should submit a Slug Control Plan to the POTV within three months
of notification and complete implementation of the Plan within six months of
approval. The Plan should detail facilities and procedures to eliminate or
minimize the slug discharge of pollutants into the sewer system vhich could

harm the treatment plant, workers, sludge, or cause an NPDES violation. The
Plan should meet the requirements and follov a format specified by the POTW.
Once approved by the POTW, the Plan will become an enforceable part of the
pretreatment permit. The POTW should reserve the right to inspect the IU to
ensure that it is adequately implementing its Plan.
The POTW should also consider meeting with company officials as part of
its review process. Site visits to confirm the equipment and procedures
described in the Plan, and follow-up inspections where development of proce-
dures or installation of or replacement of equipment were promised are also
important. In meeting with the industry officials, the POTW may consider
providing a tour of the POTW plant and/or the collection systems to increase
IU awareness of slug impacts (for example, actual evidence of previous
problems such as sewer line corrosion).
2.4.2 Inspection and Monitoring of IDs for Slug Control Implementation
Ills should be inspected to verify compliance with slug control require-
ments or plans and to ensure lU's slug risk classifications are correct and do
not need to be revised. Low- to medium-risk lUs should be inspected randomly
and infrequently. High-risk facilities should be inspected more frequently,
and regularly to determine adherence to Slug Control Plans. Many of the
facilities posing the highest slug risk are probably already significant
industries that come under the POTW's pretreatment monitoring program.
Consequently, these facilities will normally be visited often and their
wastewaters will be sampled frequently. There will, however, be high-risk
facilities which were not originally classified as significant lUs and which
should be inspected.
Before conducting inspections, it is important that the POTV inspector be
familiar with the lU's slug discharge control requirements and the Control
Plan on file at the POTW. The inspectors should seek to verify all Plan
information during the inspections. In particular, during a compliance moni-
toring inspection of a significant user already covered by pretreatment
requirements, the POTW inspector should be observing the slug control prac-
tices. The following items should be reviewed during a compliance inspection:
2-43
-------
• Verifying or updating information on facility contact, phone number,
address, chemical inventory, and slug control equipment and procedures
9 Identifying any relevant process changes, modifications to the
facility or to the discharge location
• Evaluating the condition of materials storage, transfer, and transport
equipment
• Revising facility sketches to include changes or modifications
• Continuing evaluation of evidence or potential for spills
• Evaluating progress of work for any compliance schedule
• Checking for good housekeeping and chemical handling procedures
• Evaluating containment structures.
The inspector should ascertain the lU's status with regard to compliance
with the Plan, report any deficiencies observed in the lU's current Plan, and
suggest alternatives or modifications. If an IU facility has a compliance
schedule, the inspector should visit the facility during construction and upon
completion of construction activity. Information gathered during the
inspections should be used to modify the lU's Plan as necessary.

3. POTU SLUG RESPONSE PROGRAM
Slugs may occur despite the implementation of a well-designed Industrial
User Slug Control Plan*. This chapter describes four elements of a response
action designed to mitigate the impacts of slugs which escape prevention:
• Detect and Identify Slugs (Section 3.1): through IU notification or
POTV monitoring and tracking systems.
• Coordinate response activities (Section 3.2): through an appointed
response coordinator responsible for directing a response and calling
upon local agencies for assistance (such as police and fire
departments).
• Develop appropriate responses (Section 3.3): including emergency
measures such as POTV and collection system worker evacuations,
containment of slugs, as veil as subsequent treatment or disposal
techniques.
• Follov-up measures (Section 3.4): such as full documentation and
evaluation of response effort, enforcement actions and SDC Program
reviev and modification.
Figure 3-1 depicts the organization of this Chapter.
3.1 SLUG DETECTION AND SOURCE IDENTIFICATION
While identification of a slug discharge event may come from any of
several sources (e.g., remote early warning system, notification from the IU
source, an individual or agency, or by visual or other observations of

influent vastevaters), notification from the responsible IU is the best means
of identification as IU personnel are most knowledgeable about the nature of
the slug. As discussed in Chapter 2, notification responsibilities and
procedures should be imposed on all potential slug dischargers. Nonetheless,
the POTW may not be notified in all cases.
In the absence of slug discharge notification from the IU source, the
POTW will have to rely on other methods to detect slug loadings. In large
part, detection of slugs by POTVs can be a chance occurrence, resulting in
ineffective responses. Detection methods often do not provide sufficient
warning to undertake mitigating measures or enough information to identify the
responsible party, for example, workers in the collection system or treatment
plant detecting a change in the appearance or smell of the influent, actual
upset of the treatment plant, or an explosion in a pump station, or receiving
water impacts (i.e., fish kills, etc.).
Where slugs are a potential or existing problem the POTW should implement
a systematic means of slug detection, such as:
• Regular and random monitoring in the collection system and at
Industrial Users (lUs) using instruments that provide an immediate
analysis (e.g., pH, lower explosive limit (LEL) and collection system
monitoring stations equipped with recording devices and remote
alarms). Unusual readings may be indicative of slug discharges.
• Instruments for measuring wastewater parameters register concentration
variations at the headworks or other points within the treatment .
plant.
Some POTWs may find that budget constraints and administrative procedures
limit their ability to advance funds to pay for analytical work to identify
the responsible IU. POTWs may wish to set up a contingency fund to pay for
analytical work prior to identification of the responsible IU. Once the
responsible IU was identified, the money could be collected from the IU via
fines or fees.
3.1.1 Tracking
A continuous monitoring and surveillance system can provide documentation
of the variations in influent character that will result from certain slug
3-3
-------
loadings. Based on the location of the sensing apparatus, the time of the
arrival of the slug at the plant can be estimated. Hovever, a continuous
monitoring system can be expensive. If the Ills in a community are centralized
(such as in an industrial park), monitoring costs may be reduced.
Upon detection, and once any necessary response measures are underway,
the slug loading source may be tracked by checking pump stations and manholes
upstream from the first detection point up to the discharge point. Tracking
the slug is not always successful because the slug may cease before the source
is found. However, if the collection area where the slug originated can be
determined, and the discharged material can be identified, then records of Ills
and the types of materials used by each can be checked to identify the slug
source. EPA's Guidance Manual for Preventing Interference at POTVs provides
additional information on methods for tracking slug discharge sources.
The Toxicity Reduction Evaluation Protocol for Municipal Vastewater
Treatment Plants also may help the POTV identify slug sources of toxicity.
Methods are presented in the manual for collection system tracking and
toxicity treatability tracking when a substance (known or unknown) is pro-
ducing POTV effluent toxicity and for toxicity identification evaluation.
These methods may be useful in identification of individual causative agents
in slugs, including components of mixtures received as slugs.
Following are some examples of POTW programs: the Hampton Roads
Sanitation District (HRSD) in Southeastern Virginia maintains a comprehensive
tracking system of industrial wastes generated from over 300 sources,
including military installations, manufacturers, and food processors. IU
discharges may be tracked in one of two ways:
• HRSD employs field teams, supplied with radio-equipped vehicles and
extensive field and laboratory sampling equipment. These stand-by
personnel check pump stations and sewer lines in a downstream to
upstream fashion to isolate the pollutant source. Collected samples
are preserved as evidence.
• HRSD also sets up automatic sampling equipment at key locations
throughout a service area. The samples are collected and analyzed
daily. Once pollutant concentration trends are determined, the
samplers are moved upstream repeatedly until the problematic source is
located.
3-4
-------
In either case, once the source is located, the industry in violation is
contacted and is required to pay all costs associated with the investigation
and cleanup. HRSD has determined that vhile use of a highly visible indus-
trial waste investigative team has deterred Ills from unauthorized discharges,
it has been most effective in tracking chronic discha-rges. It is estimated
that the rate of such unauthorized discharges has decreased y more than
40 percent in the past 8 years.
The City of Baltimore, Maryland, has established a data management system
as part of its industrial waste control program. The system generates monthly
listings, called "Daily Average Mass Discharge Reports," of ID discharges.
The report groups companies by sewer service area, chemicals used, stored,
and/or discharged. If a chemical compound (such as a solvent) slug is
identified by a tracking team or through sample analysis techniques, a search
of the data management system can locate potential industrial sources of the
compound in question. Again, this type of system is most useful for tracking
chronic discharges, but may be beneficial for addressing isolated slugs.
3.1.2 Sampling Analysis
The investigation of a slug should include sampling and analysis of the
discharged material in the collection system or at the plant site. The POTV
should have adequate sampling equipment that can be used during a slug.
Identifying the slug material is essential to identify the slug source,
determining the need for clean-up, or determining whether additional control
measures are needed to prevent a recurrence.
The personnel taking samples should be knowledgeable about the appro-
priate sampling techniques, methods of preservation and chain-of-custody
procedures. Analyses of samples may be performed in the POTV laboratory or at
a commercial laboratory. If the POTV routinely uses a commercial laboratory
to perform analysis of wastewater samples, the POTV should establish a con-
tract with the laboratory to provide emergency analytical services.
Sampling can be conducted either manually or through the use of automatic
devices. Normally a grab sample or multiple grab samples will be appropriate
3-5
-------
for the analysis of slug material. If possible, samples should be taken of
the virgin material, of the flow immediately downstream of the slug discharge,
and at the POTV. Extreme care must be exercised in selecting sampling devices
and procedures to avoid the potential for sampling error. A good reference
for sampling procedures is the EPA document, NPDES Compliance Sampling
Inspection Manual (USEPA, 1984) available through the National Technical
Information Services (NTIS).
Once an accurate sample has been obtained, several steps should be taken
to ensure that the validity and objectivity of the monitoring operations are
maintained. The sample should be properly preserved and promptly delivered to
the laboratory to prevent sample degradation. Proper chain-of-custody proce-
dures should be used where such procedures will not hinder response to a slug
discharge. Sample preservation techniques and holding times are outlined in
various analytical handbooks, such as the EPA Manual of Methods for Chemical
Analysis of Water and Wastes, available through NTIS, and Standard Methods for
the Examination of Water and Vastevater, 16th Edition.
3.1.3 Recordkeeping
Good recordkeeping is an important element of the response program since
documentation of the events surrounding the slug discharge and its cleanup may
be important in cost recovery or reimbursement. The records may provide
useful information for future slug situations. It is good practice after
completing a slug discharge response action to evaluate the response measures
taken to identify possible improvements. It is also important to establish
procedures and forms to simplify recordkeeping during response to a slug
discharge to ensure that safety, liability, or other important issues are not
overlooked. Recordkeeping can be postponed during emergency response periods,
where infeasible or hindering response actions.
The POTV Emergency Response Coordinator (see Section 3.2) should keep a
permanently bound book, log, or diary, documenting the chronological events
(from notification to cleanup). All events and actions of any significance
should be recorded in the log as soon as possible vith notations of the date
and time, including records of flov, opeua-icn. personnel in'"l"ed.
3-6
-------
maintenance sampling, problems encountered, telephone conversations, meetings
held, orders, issues, and weather observations.
Forms indicating all of the information needed for appropriate documenta-
tion of a slug discharge event can be used to supplement the log book. Sample
forms are provided in Appendix C. The forms address documentation of the
initial report on the incident, listings of all key events pertaining to slug
loading response and cleanup, and a recommended format for a final report.
The forms also include the names of national, regional or local organizations
that can assist during a slug incident.
3.2 RESPONSE COORDINATION PROCEDURES FOR SLUGS OF HAZARDOUS MATERIALS
Generally, POTWs have the expertise and resources to respond to non-
explosive or nonreactive slug loadings. For example, influent flov equaliza-
tion can be one means of handling a high BOD slug. However, for spills of
explosive or reactive materials, the POTV may require assistance from other
agencies. It should be up to the POTV to ensure that the groundwork for
coordination is put in place during its POTV slug control program development.
This section discusses emergency coordination for response to hazardous
material spills. Section 3.3 discusses POTV response measures relevant to a
wider variety of slugs.
The POTV should designate an Emergency Response Coordinator (hereinafter
referred to as the Coordinator) who will direct the response effort or
represent the POTV in assisting an IU or primary local agency responsible for
response efforts. The POTV personnel receiving information concerning a
hazardous material slug should call the Coordinator, who will evaluate the
information and direct the further actions of the POTV and IU personnel. A
suggested format for notification is shown in Appendix C.
During Slug Control Program development, the Coordinator should meet vith
local industries, local emergency planning committees under SARA Title III,
fire, police and public health departments, State Emergency Response Teams,
etc., to identify available resources and efficient coordination of response
equipment and personnel. The purpose of the neerings is to inform public
3-7
-------
agencies of the adverse effects of slugs and the need to coordinate response
efforts to prevent additional harm or duplication of effort.
The POTV should develop a listing of all agencies that may respond to
slugs. The contact names, addresses, telephone numbers, and the available
services (i.e., manpower, equipment) provided by each source should be listed.
Neighboring jurisdictions or industries vith specialized equipment may be
willing to help when accidental spills occur. A listing of national organiza-
tions that may be of assistance is included in Appendix C.
Response procedures should be drawn up with detailed instructions
designating the lead agency and contact persons, provisions for notification
of other agencies, access to equipment, and follow-up review procedures. If
possible, these procedures can be written in a formal agreement (such as a
Memorandum of Understanding) and signed by all of the participants.
In addition, communication equipment will assist the POTV in response
efforts. The equipment may include telephones, CBs, and short wave radios,
which will keep key individuals involved in the response in contact with each
other and will facilitate coordination of slug loading response efforts.
Cooperation also yields the benefits of additional resources and expertise.
The local police and fire departments may already have personnel
specially trained in handling materials spills. For example, Los Angeles
County has a Toxic Strike Force which serves to coordinate enforcement by the
POTW, fire, police, and public health departments. Many fire and police
departments have a Hazardous Materials Unit staffed 24 hours a day with
specialized personnel available for response anywhere in the city, or county
or neighboring jurisdictions. These units may be equipped with positive
pressure breathing apparatus, acid gas suits, explosives meter, radiological
markers, kits for stopping leaks, absorbent material, recovery drums, and
manuals for identification and handling of hazardous materials. The fire
department may be able to train the POTV staff in the proper response pro-
cedures, and may help contain explosive materials or toxic ait: releases at 'he
POTV.
3-8
-------
In an emergency, other responders, such as the fire department, may
determine that the easiest solution is to flush a spill down the sewer. This
is particularly prevalent when responding to spills of flammable materials,
such as a tank truck accident where gasoline and chemicals could be discharged
into a combined sewer. Continued flushing could occur until the concentration
of combustible gas in the sewer system reaches 100 percent of its lower
explosive limit (LEL). Once this condition has been reached, there is an
adequate concentration of gas to support combustion. Volatile compounds could
accumulate at pump stations and be hazardous to workers there. In these
situations, the knowledge and experience of the POTW officials is critical in
determining the best course of action, and if the spill is to be flushed, or
has been flushed, what action is needed to protect the workers, collection
system, and the treatment plant. Knowledge of this danger might lead to the
evacuation of the pump station).
In many POTWs, the treatment plant itself and the collection system, or
parts of the collection system, are maintained by separate crews (of the city
or county, or by other cities). In such instances, the POTW may not be
directly responsible for the collection system, and coordination between the
responsible agencies becomes extremely important. In responding to a slug
discharge that has reached the collection system, the POTW personnel should
contact the agency responsible for the maintenance of the collection system.
Additionally, if the collection system staff identifies unusual corrosion of a
pipe or wastevater with unusual characteristics, the staff should be aware of
the notification procedures developed to alert the POTV.
3.3 GENERAL POTV SLUG RESPONSE MEASURES
Once dangerous slug materials enter the collection system, there may be
several potential effects:
• Hazardous vapors resulting from the slug may back up the sewer lines
into residences, or other industrial facilities, creating additional
hazardous situations
• POTV personnel may be endangered, or the collection system or plant
facilities may be damaged
• Materials may pass through the treatment plant unaltered and be
discharged to the receiving water
3-9
-------
• Biological treatment processes may be upset, and the time required to
re-establish maximum efficiency may be considerable, resulting in
discharge of poorly treated wastevater
• Biological treatment processes may remove or reduce the quantity of
discharged materials entering the receiving stream; however, floatable
or settleable solids may need to be disposed of, and sludges may be
contaminated.
These effects will be a function of the type and quantity of released mate-
rial, contingency reactions, and types of treatment processes at the POTU.
The following sections define initial response measures, containment and
diversion, treatment, waste disposal, and associated safety concerns to
prevent the adverse effects caused by slug loadings.
3.3.1 Initial Response
Monitoring, venting, dilution of the material in the collection system,
or containing the material should come first. Which of these is the appro-
priate response actions will be dependent on the type and quantity of the
released material and how quickly the POTV learns of the incident.
If the POTV is notified soon after a slug, the collection system should
be reviewed to determine where the slug will travel in the collection system.
A crew can then be dispatched to locate the leading edge of the slug. Sites
downstream from the slug can then be identified and utilized as possible
containment areas. Another crew can monitor the site of the slug and work
downstream to mitigate damage to the collection system.
If the flow is flammable or explosive and is expected to go through any
metering installation, the appropriate officials should be directed to put the
facility out of electrical service. Additionally, all downstream industrial
facilities, commercial establishments, or residences that could be endangered
should be notified and the necessary precautions taken. Proper venting and
any necessary dilution of flow in the collection system should be handled by
appropriate maintenance crews along the discharge route. If the flov ot the
slug will enter any sewage pumping station, all personnel stationed at the
pump station (or people sent to the facility ir response to Mie 3 lug). =noul-.i
be advised of any potential danger.
3-10
-------
Depending on the quantity and type of material involved in the slug, a
decision should be made whether to attempt to capture and remove the material
from the collection system or to let it flow to the treatment plant.
Approximate flow rates through the collection system should be established
beforehand through the use of dye studies conducted by the POTV throughout the
system to determine the high and low flow rates from particular industries to
the treatment plant. This will allow for the selection of containment
locations based on these flow rates. The decision to contain the slug, and
where the discharge should be contained, should be made by the Coordinator
based upon the hazards involved.
A monitoring and surveillance system can help with implementation of slug
discharge countertneasures at the plant or in the collection system. Test dye
runs throughout the collection system during nonemergency times can be used to
calculate estimated flow rates through the sewer from specific industries or
areas. These flow rates can be used to calculate travel time from the source
of the slug to a pump station, another industry, a residential area, or the
treatment plant. This effort can result in a better response during a slug
loading by providing the necessary information to decide on evacuation,
containment, and cleanup actions.
If the slug material has reached the treatment plant, all available
information concerning the material type and quantity discharged should be
provided to plant operating personnel who will be able to advise the response
team whether containment and subsequent removal of the material is possible.
If removal is not possible, the plant personnel can bypass the material around
specific unit processes rather than allowing the slug to go through the normal
treatment process. The agency administering the NPDES permit program (State
or EPA) should be notified of potential problems and engaged in discussions of
any need to bypass, if possible.
3.3.2 Containment and Diversion
Measures to contain the spilled material near its source and prevent it
from reaching the collection system can include:
3-11
-------
• Changing position of the ruptured container or tank
• Repairing or rebuilding the container, tank, or containment structure
• Building a substitute tank or containment structure
• Enclosing the container, tank, or containment structure.
A substitute containment structure may be made by:
• Forming dikes from earth, sand bags, or inflatable water bags
• Erecting temporary tanks or containment structures
• Digging a pit or sump, preferably lined.
Sewer drains should be blocked when they present an avenue of continued
spreading of the spilled or discharged material. In the absence of high-
expansion foam systems, materials at hand should be used to form dikes (e.g.,
sand bags). In-sewer means of control include inflatable plugs, "pipestop-
pers," or dams usually used in sewer maintenance.
Within the treatment plant, the operator may be able to divert and
contain the discharged material, provided he has been forewarned and is
adequately prepared. Consequently, the POTV should obtain or have access to
all necessary containment and diversion equipment that is likely to be used
during response to a slug. For example, a treatment plant containing several
units (primary clarifiers or activated sludge) can allow the flow with
discharged material to enter specific units. By operating appropriate valves,
the flow to the units with captured material can be turned off and contained
material can be removed or processed, if possible. The EPA Guidance Manual
For Preventing Interference at POTVs discusses diversion and process
modifications that can be conducted at the treatment plant to mitigate the
effects of slug discharges.
Other types of equipment that may be required for slug response efforts
include fire-fighting equipment, decontamination equipment, and spill control
and cleanup equipment. To ensure the availability of this equipment, the POTU
should consider agreements with local fire and police departments, neighboring
POTVs, and nearby industries to borrov appi or'"1-?r
-------
local contractors equipped to clean up spills. Spill response equipment
should be available to the POTV. Such equipment should include:
• Temporary containment devices (e.g., booms)
• Absorbent materials
• Spill cleanup tools
• Ventilation equipment
• Liquid vacuum pumps
• Containers for storing spilled material
• Decontamination equipment.
3.3.3 Treatment
Upon identification and containment of the released material, appropriate
treatment can begin. Table 3-1 presents treatment alternatives for 19 groups
of hazardous material slugs that may be implemented in the collection system
or at the POTW. Factors such as volume of the discharge, time, location, and
availability of equipment and supplies will dictate the appropriateness of any
given countermeasure. The POTV can increase the number of in-plant treatment
options with in-plant modifications, for example, with a modification to
provide chemical addition between grit removal and pre-aeration, the chemical
sludge could be settled in the primary clarifier.
3.3.4 Discharge and Sludge Disposal
If the slug consists of hazardous substances, the slug material treated
at the treatment plant of the POTW may contaminate the sludge or pass through
the plant. Contaminated sludge and the material collected at the IU or in the
collection system could be classifiable as a hazardous waste, and therefore
vould have to be disposed of according to RCRA requirements. Even if the
sludge is nonhazardous, it may still need to be disposed of in a nonroutine
manner. The POTV should evaluate the availability of local contractors/
haulers for transporting, and hazardous waste disposal options for ultimately
disposing of contaminated sludge or collected material before such a need
arises.

Dilution (20 or SO to 1) is * technique that may often be used when little is known about th» spilled materials.
often the materials need to be contained for long periods of time II day to weeks) to allow for acclimation and growth of bacteria for
adequate oxidation of pollutants.
3-14
-------
POTWs that identify a high risk IU with a potential for slugs that would
result in sludge disposal problems should determine the available disposal
options during Slug Control Program development. Response actions may be
modified dependent upon the disposal option or even OSHA requirements. If
response or disposal options are severely limited, the POTV may require the IU
to develop stringent Slug Control Plans that are strictly enforced.
If the slug material might or is expected to pass through the plant, the
effluent toxicity should be measured to determine the effect of the slug on
the receiving water. If it appears that toxicity may occur, mitigating
measures such as recirculating or removing the effluent for further treatment
may be required. Continued monitoring of the effluent also may be necessary.
If the slug results in an upset of the POTV or NPDES permit violation, the
POTV should notify the State/EPA NPDES authority.
3.3.5 Safety Considerations
The safety protocol for hazardous materials response-may vary with the
types of slugs. The safety protocol may also be affected by the requirements
of an OSHA emergency action plan or contingency. However, the basic elements
of any hazardous material control plan should include:
• An Emergency Response Coordinator, with assigned responsibilities and
authority
• Clear staff responsibilities, including Hazardous Material Safety
Officers
• Exposure minimization
• Safety supervision
• Proper safety equipment.
At the POTV, the Coordinator must clearly be in charge and able to assess
the situation and direct activity to remediate the slug's impact. An
effective safety program should also include training of the response team to
identify and interpret chemical hazards.
In addition, the number of people exposed in the immediate danger zone
should be kept to the absolute minimum. Proper safety clothing, safety
3-15
-------
equipment, and work equipment appropriate to the physical and chemical hazards
should be a prerequisite for entry into the danger zone.
Safety equipment necessary for a slug of a potentially hazardous nature
should include:
• General first aid kit
• Eye and skin contact response kits
• Explosive and toxic gas detectors
• Proper lighting and warning equipment (e.g., barricade, traffic cones,
flashing lights).
The following equipment should be made available to any personnel exposed to
hazardous materials.
Protective Clothing Respiratory Protection
• Total encapsulation unit • Self-contained breathing apparatus
• Rubberized rain gear • Gas mask with organic vapor canister
• Disposal coveralls • Half mask respirator with dust cartridge
• Normal working clothing • Disposable dust respirator.
The type of clothing or respiratory protection required for different situa-
tions should be designated (e.g., the operator should know when he or she must
be wearing disposable coveralls and a gas mask with an organic vapor car-
tridge). As the potential for exposure decreases, the levels of protection
can be decreased. Supervisors, who are required both to use protective
equipment and to supervise workers using the equipment, should complete the
safety training program.
3.4 FOLLOV-UP REVIEW AND ACTIONS
A follov-up review of a spill is important in evaluating Ill's Slug
Control Plan and POTW Slug Control Program and in providing a comprehensive
summary of the key aspects of the event. The POTV should conduct a follov-up
review of the incident and the ID'S repoi'. arv.i "lire a comprehensive final
3-16
-------
report. The final report documents the event and may serve as a reference
during reviews of the ID Plan or POTW Program, or during the occurrence of
similar slug discharges in the future.
This section discusses the procedures that a POTV can use in conducting
the review and highlights areas of concern that should be investigated during
the review. Procedures for requiring modification of the ILJ Slug Control Plan
and instituting civil and monetary penalties also are discussed in this
section.
3.4.1 Review of IU Follow-up Report
In cases where an IU was identified as the source of a slug, a written IU
report should be required within five days. The POTV should review this
information as part of its follow-up review. This report should address the
cause of the slug and precautions that will be taken to prevent a recurrence.
The IU also should provide an evaluation of the slug discharge response
capabilities onsite and how they will be improved in the future.
The lU's Plan should be reviewed after the incident to determine any
deficiencies in implementation. The POTtf should identify the deficiencies in
the'IU's design or implementation of its Plan. The Plan may be determined to
be inadequate, or a well-designed Plan may not have been implemented properly
and revision should be required.
In some cases, the corrective measures required at the lU's site where
the slug discharge originated could require time (e.g., structural modifica-
tion such as installing dikes, curbs, etc.)- The IU should be provided with a
compliance schedule to implement all necessary slug discharge prevention meas-
ures within a reasonable time.
If the source of the slug did not have a Plan because it was not
classified as a high risk, then the IU should be evaluated and required to
develop a Plan if necessary. The Plan should address measures taken by the IU
to- f>.r.event further slugs.
3-17
-------
3.4.2 Penalties
The POTV should evaluate its authority to recover the costs of slug
response and of the damage to the POTV and the collection system. The POTV
may have the authority to enforce civil or criminal penalties against the Ills
that violate the prohibited discharge standards or requirements as established
under the POTW's pretreatment program. Legal remedies and emergency relief
are presented in EPA's Guidance Manual for POTV Pretreatment Program
Development and the Pretreatment Compliance Monitoring and Enforcement
Guidance.
3.4.3 POTV Slug Control Program Review and Modification
After the slug incident is concluded, the POTV should review its Slug
Control Program. Any problems encountered by the POTV during response or
follow-up activities should be analyzed. This analysis may indicate defi-
ciencies in the POTV's Program. Corrective measures can then be devised to
improve the Program.
Deficiencies could include inadequate enforcement authority, an inability
to collect fines and penalties, lack, of coordination between the various
groups and agencies involved in slug control, inappropriate sampling pro-
cedures, and poor documentation. Some examples of modifications could be:
• An industrial discharge sampling program for collection and treatment
systems located in heavily industrialized areas may be desirable for
continuous maintenance of satisfactory plant performance and effluent
quality and determining potential slug discharges.
• A monitoring and surveillance system could be installed at critical
points in the collection system and at the head end of treatment
plants to facilitate activation of slug discharge contingency plans.
• Emergency response agencies (e.g., police, fire) could be trained to
handle hazardous materials spills, be informed of the alternative for
handling spills, and be informed of the ramifications of these
alternatives regarding wastewater collection and treatment systems.
• The potential for spills and batch discharges of hazardous materials
may need to be reassessed. A more thorough inventory of hazardous
materials stored within the POTV service area may be varranted. If
the POTV already has such an inventory, it may need f? be updated
regularly.
3-18
-------
t Disposal options for released materials or other contaminated materi-
als may need to be investigated. The hazardous material content of
sludge resulting from slug discharges or chronic discharges of
industrial wastes may need to be quantified. The additional costs
incurred for disposal of hazardous materials also could result in a
re-evaluation of the budget for slug discharge control.
Depending on the specific problems encountered by a POTV during a slug,
appropriate modifications should be implemented to improve future slug
control and response, and prevent recurrence.

PREVENTATIVE MAINTENANCE
All areas should be checked frequently for leaking valve steam, seals,
and gaskets. Have leaks repaired as soon as possible. Before disconnecting
any piping, make sure that all isolation valves are completely closed.
Routinely check all instrumentation for proper operation. Any abnormal
reading should be investigated. Extreme temperatures or pressures on closed
ta^.ks can result in the automatic opening of their relief valves and the
spilling of contents.
Although most tankage has collision protection, fork trucks and tank
trucks should be driven vith utmost caution. No material should be handled by
a fort truck without a proper pallet. Follow all vehicular warning signs.
D-4
-------
During rav materials or product mixture transfer, all piping and hoses
should be checked to make sure they are properly connected. Connections that
are misshapen or have worn gaskets are to be repaired or replaced, as are vorn
hoses or corroded piping. Hoses are to be kept out of traffic lanes, and all
values are to be closed and hoses disconnected before tank trucks are moved.
Inspections will be conducted weekly as part of a typical preventive
maintenance program. Abnormalities will be recorded and duly noted to the
Spill Response Coordinator.
SLUG PREVENTION PROCEDURES
The following are routine operation and maintenance procedures to
minimize slugs. They are not substitutions or replacements for competent
operation and maintenance of the plant.
A spill may still occur despite the implementation of spill preventive
measures. All spill response activities can be grouped into the following
categories:
• Safety measures
• Acquisition of assistance/notification
• Spill containment/diversion/isolation.
During spill response, the above-described activities must be carried out
in the order shown. If adequate spill prevention and control measures have
been taken, emergency spill control may not be necessary; therefore, although
spill control is of great importance, safety and notification are to be
addressed first. Spillage of ingredients or products which may not be toxic
can cause a slug load at the treatment plant.
To minimize the chance of a batch discharge of washwater resulting in a
slug loading to the POTV, all wash operation batch discharges must be tested
for pH and neutralized if necessary. In addition, the discharge must not
exceed a BOD level of 250 mg/1.
D-5
-------
The safety of personnel and the community is of paramount importance at
the time of any chemical spill. The threat to human health depends upon the
nature, quantity, and location of the material spilled. Every spill or slug
discharge is unique, and there is no substitute for sound, professional onsite
assessments; but certain general safety considerations can be delineated.
• Personnel should be evacuated from areas where flammable, explosive,
reactive, or noxious/fuming chemicals have been spilled in large
quantities (e.g., in areas that are not ventilated).
• All heated or flame-producing apparatus in the vicinity of a flammable
material spill should be immediately shut down and/or cooled. Exposed
steam lines within such areas should be valved off. Obviously,
personnel should not create any flame or spark within such an area.
• Incompatible materials stored in the vicinity of a spill must be
moved. Bagged cleaners,for example, must be moved from the scene of
an acid cleanser spill. Reductant chemicals should similarly be moved
from the scene of an oxidant spill. (Such measures should be taken
only when the safety of industry personnel performing the tasks is
assured.)
• Breathing apparatus should be immediately provided to all personnel in
the vicinity of a fire near noxious or fuming chemicals. If no
apparatus are available, do not attempt to go near the fire or
extinguish it; the fire department is trained for such matters.
Because such chemicals may also be corrosive oxidants, oxidation-
resistant clothing will also be essential.
• Spill response personnel should carefully weigh each spill response
action in terms of safety. Incorrect response activities sometimes do
more harm than good. For example, fans may not be a good choice of
equipment for ventilating noxious fumes; if the fumes are flammable or
explosive, the fan's electrical motor could spark a fire or explosion.
Caution is the watchword.
Acquisition of Assistance
The industry spill response coordinator should contact the wastewater
treatment plant and fire department immediately upon ensuring the safety of
industry personnel onsite. These local agencies can provide assistance in
spill response and onsite cleanup coordination. In the case of a fire and/or
explosion, the fire department will provide remedial action expertise. The
industry may also be required to contact the County, State, or Federal agency
D-6
-------
responsible for emergency response. A quick assessment of the severity of the
spill will dictate the need to call the vastevater treatment plant or the fire
department before other concerned agencies are officially notified.
The fire department can be notified by calling dispatch at 911.
The vastevater treatment plant can be notified by calling (101) 212-6574.
Spill Containment/Piversion/Isolation
The next highest priority in immediate spill response activities is spill
isolation. Clearly, the first spill response step after safety considerations
are met should be to stop the flov of material being spilled. This activity
consists of shutting valves and/or stopping pumps from feeding chemicals to
the vessel generating the spill. Generally, the size of a spill can be
limited to a single tank volume or less if prompt action is taken.
Containment diversion activities depend upon the nature of the material
spilled. The following are intended as guidelines for handling ingredient
product, and cleanser spills:
Ingredient and Product:
In the event of a spill, dam the spill area and plug the drain. Scoop or
pump the material into vaste drums. Cover the containers and move them out of
the spill area. Clean the area through normal cleanup procedures. Dispose of
the material by landfilling it or making it available to local farmers.
Cleansers:
The following chemicals are used in our cleaning process. Follov these
steps vhen handling an accidental spill. Each product's Material Safety Data
Sheet (MSDS) is appended to this plan.
Chloroshine: Granular Povder (Val-Chem). Use proper protective equip-
ment. Keep combustibles away from the spill area. Carefully sveep up
and shovel into dry containers without raising dust. Cover containers
and move containers out of the spill area. Flush area with water, and
follow with normal cleanup procedures.
D-7
-------
H.D.C.-3: Granular Powder (Val-Chem). Use proper protective equipment.
Keep combustibles avay from spill area. Carefully sweep up and shovel
into dry containers without raising dust. Cover containers and move
containers out of the spill area. Flush area with water, neutralize with
a diluted weak acid (such as Acidize), and follow with normal cleanup
procedures.
Power Spray: Granular Power (Val-Chem). Use proper protective equip-
mentKeep combustibles away from spill area. Carefully sweep up and
shovel into dry containers without raising dust. Cover containers and
move containers out the of spill area. Flush area with water, and follow
with normal cleanup procedures.
M.S.R.-200: Liquid (Val-Chem). Wear protective equipment including
rubber boots.Stop leak if you can do so without risk. Dike or dam
large spills. Soak up with sand or other noncombustible inert absorbent
materials. Flush area with water and follow with normal cleanup pro-
cedures. Keep combustibles away. Be careful, as spills are slippery.
Acidize; Liquid (Val-Chem). Vear protective equipment including rubber
boots.Stop leak if you can do so without risk. Dike or dam large
spills. Soak up with sand or other noncombustible inert absorbent
materials. Flush area with water and follow with normal cleanup pro-
cedures. Keep combustibles away. Be careful, as spills are slippery.
Microsan: Liquid (Janco United). Wear protective clothing including
goggles, rubber boots, and rubber gloves. Before entering a confined
space, monitor for oxygen and ventilate the atmosphere. If ventilation
is not available, wear a self-contained breathing apparatus. Dike or dam
large spills. Soak up spill with sand or other noncombustible inert
absorbent materials. Flush area with water and follow with normal
cleanup procedures. Keep combustibles away. Be careful, as spills are
slippery.
Slug Response, Follow-up Reporting, and Documentation Procedures
The follow-up reporting and documentation procedures to be followed after
a slug are described below. Two major questions must be addressed in this
documentation:
• What 'caused the incident, or how can it be avoided in the future?
• How effective were response and cleanup activities, and how can
response procedures be improved?
The facility will then follow-up with an internal investigation to
ascertain what sequence of events lead to the incident. Two factors
contribute to the occurrence of most slugs:
D-8
-------
• Improper process operations
• Insufficient inspection and maintenance programs.
Poorly maintained process and storage equipment can also result in slugs.
The following will be noted:
• Tanks—condition of welds
• Drums—extent of corrosion, deterioration
• Pumps, valves—condition of seals, packing
• Spill prevention equipment--availability, appropriateness, condition.
The investigation will also report on the adequacy of our response
procedures. The following items will be addressed:
• Was the safety of industry personnel and the surrounding community
protected throughout the incident?
• Were personnel working close to the incident provided adequate access
to breathing apparatus, protective clothing, and other safety devices?
• Was the slug material confined quickly?
• Was fire extinguishing equipment adequate and readily available?
• Were appropriate wastewater treatment plant and fire department
officials immediately notified of the incident?
Upon completion of the above-described investigation, improved opera-
tional, inspection, maintenance, and/or slug response procedural recommenda-
tions will be made in the investigation report. The investigation report will
then be made available to the wastewater treatment plant, fire department, and
insurance firms (if applicable) to assist these agencies in their own
investigations.
SLUG PREVENTION TRAINING;
This plan represents a working document for all plant employees. At the
start of their employment, all new employees will receive training consistent
with this plan. All current employees will be trained when this plan is
D-9
-------
implemented. Each year, employees will receive a brief refresher course.
All employees vill be made avare of changes to this plan as they are
implemented.
The information employees receive must include:
A. The requirements of OSHA Lavs
B. Any operations in their work area where hazardous chemicals are
present
C. The location of the Slug Control Plan and list of hazardous chemicals
and material safety data sheets.

A. Methods and observation that may be used to detect the presence or
release of a hazardous chemical. The employees should be informed of
the visual appearance or smell of the chemicals so they will know
when they are being released into the atmosphere. They should also
understand all monitoring surveillance and alarm procedures.
B. The physical and health hazards of the chemicals in the work area.
C. The measures employees can take to protect themselves including:
1. Specific procedures implemented to protect employees from
exposure to harmful materials
2. Emergency response procedures
3. Personal protective equipment, etc.
4. Processes used to protect employees.

REPORTABLE MATERIAL DATA
Table A is a list of chemicals present in large quantities. It includes
all substances that are listed, or have components that are listed, as
hazardous materials and are present in quantities greater than 55 gallons or
the Reportable Quantity (RQ) of the hazardous material.
SLUG PREVENTION
All drums are to be marked with a hazardous waste label and must be
sealed at all times vhen not being filled or dispensed from. Drums put up in
the dispensing rack are to be fitted with approved faucets and pressure relief
devices. Drip cans are to be kept under facets at all times.
Plating tanks must be visually inspected by the shift supervisor at the
beginning and end of each shift for any signs of leakage or potential prob-
lems. An inspection log will be maintained by the safety officer.
All batch operation discharges must be tested for pH and neutralized if
appropriate. Continuous pH monitoring must be conducted during discharge.
SPILL CONTAINMENT
The first concern is to stop the source of the spill and provide ventila-
tion to the area. Leaking containers must have their contents reconfined by
transferring the chemical or confining the container. The spilled material
must be kept from reaching a floor drain or from soaking into the ground.
Inert absorbent material, rags, paper towels, and such can all be used to sop
up such a spill or dike it away from a sewer or open ground. Do not use iron
or any item that could spark a flammable material while cleaning up. Wear a
respirator for cleaning spills of over 1/2 gallon. If a solvent odor is
strong, clear the area of all but the cleanup crew, who must wear respirators.
Neoprene gloves and boots will have to be used by the cleanup crew unless more
inert material is available. Contaminated earth must be dug up and drummed
for disposal. For a spill of a few gallons, the best procedure is to isolate
the spill and soak it up with inert media, taking all safety precautions and
disposing in a flammable waste can. Larger spills will require a separate
D-15
-------
disposal drum and a more extensive cleanup. If a spill results in the
material reaching the sever system, stop the municipal drain and halt any more
solvent from reaching the sever, and notify the appropriate authorities.
EMERGENCY RESPONSE EQUIPMENT INVENTORY
1. 8 SCBA emergency air packs (Lab)
2. 21 fire extinguishers (located throughout the facility)
3. 20 gallons of acid neutralizer (Waste Treatment Room)
4. 8 sets of protective clothing (Lab)
5. 50 Ibs absorbent material (Waste Treatment Room)
6. Portable eye shovers
7. Fire alarms.
EMERGENCY RESPONSE PROCEDURES
Any employee discovering the release of any toxic or potentially haz-
ardous material that is not readily controlled must activate the emergency
alarm and notify an emergency coordinator. The name and phone number of the
emergency coordinator is posted throughout the facility,
In the event of any release of potentially toxic or hazardous materials
necessitating evacuation, the emergency coordinator will assess the situation
and notify all appropriate agencies.
Control and containment of any spill of hazardous materials will be
accomplished through the use of materials and procedures readily available
throughout the facility and manufactured specifically for the materials
involved.
It is not anticipated that outside contractors vill be utilized, however,
the companies listed belov have available the necessary equipment and manpower
for cleanup of a spill:
1. Spill Avay Phone: (111) 777-8888
2. Cleanland, Inc. Phone: (111) 777-9999
D-16
-------
SLUG REPORTING PROCEDURES
After any reportable incident, a member of the emergency coordinators
group will notify the EPA Regional Administrator and any appropriate State and
local agencies that all appropriate follow-up actions have been implemented
per the facilities' Slug Control plan. This and all other needed reports will
be processed within five days of the incident.
TRAINING
All personnel involved in manufacturing and cleanup activities will
receive instruction in the proper handling and disposal of chemicals and
cleanup materials in order to keep regulated materials out of industrial
wastewater. New employees will be trained in these procedures immediately.
All personnel working in these activities must be familiar with this plan and
must follow the procedure established to eliminate regulated materials from
entering the wastewater system.
Training consists of classroom instruction which reviews the following:
1. The chemicals known to be used at the plant and the areas in which
they are used
2. The location of lift stations and drains with emphasis upon the
location of pretreatment system systems for each area in the plant
3. The Slug Control Plan and the proper procedures for handling and
disposing of hazardous materials.
