APPENDIX A
FLOW MEASUREMENT
Flow measurements (see Section 5) are required for each of your facility's regulated processes
and as identified in Section 4 of the BMR. The schematic diagrams in Attachment 2 must indicate
where these measurements were made. If you are unsure of exactly where flow monitoring is
required, contact the agency listed in the cover letter to this BMR.
Wastewater is generally discharged in two ways; via continuous or batch operations. Continuous
operations discharge wastewater whenever the manufacturing process is operating. Typically,
continuous processes use overflow weirs or a continuous inflow of new water. Because no
specific actions are required by the plant operators, continuous wastewater discharge is the most
common type of industrial discharge.
Batch discharges, on the other hand, occur when a tank containing wastewaters or spent solvents
is opened and allowed to drain into the sewer. Thus, batch discharges are released all at one
time. Typically, a drain or valve must be opened or a plug removed to start a batch discharge.
Many facilities use both continuous and batch discharges. For example, rinse waters are often
discharged on a continuous basis, and chemical baths are discharged on a (more infrequent)
batch basis. The type of discharge(s) (batch or continuous) used at your facility will determine
how flow measurements must be made. The measurements required for each of these types of
discharges are discussed below.
Batch Discharges
Flows for batch discharges are estimated by determining (1) the volume discharged by each batch
process, and (2) the frequency of discharge (i.e., once a day, once a week, once a month, etc.).
Continuous Discharges
Industries discharging wastewater on a continuous basis must report the average daily flow rate
and maximum daily flow rate of wastewaters discharged from each regulated process.
In instances where no significant water loss or addition takes place during industrial processing,
waters entering the process can be metered in lieu of metering process wastewater directly.
Metering these incoming waters can be done with a standard water meter. This type of meter is
suitable only for waters under pressure. It measures the velocity of the flow and converts it to
volume. Metering incoming water is usually less expensive than metering wastewater. However,
in many instances, the metering of water entering the process will be inconvenient or
unrepresentative of wastewater volume flows. In these instances, direct measurement of the
wastewater flow will need to be made.
Unlike incoming process waters, which generally come in under pressure, wastewaters originating
from most industrial processes flow through a partially filled pipe or channel. To measure these
flows, the surface of the flow must be visible and there must be adequate room to install flow
measurement devices. The most commonly used device for measuring open channel flow are
weirs or flumes. These devices raise the water level to varying heights depending upon the
Page 12
amount of flow going past. The water level is measured by a probe or other device and
transmitted to a meter which converts height to flow rate and provides a continuous record.
There are a number of manufacturers of flow metering equipment who can advise you of the types
of metering systems that will work best for your application. When selecting equipment, the
following points should be kept in mind:

Flow metering equipment usually will have to be used in conjunction with automatic
sampling equipment (see Appendix B). Both should be compatible and selected at the
same time.

Flow metering will be needed not only for the Baseline Monitoring Report, but will most
likely be a continuing regulatory obligation. The equipment selected should satisfy your
long-term as well as your short-term needs.

Flow meters should totalize the flow; that is, the meter should provide a continuous record
of the total volume of water that has flowed past the metering point.

Flow meters should have sufficient range to handle both peak and minimum flow rates.

Certain characteristics of industrial wastewaters, such as high oil and grease, high
temperature, corrosiveness, high solids, or surface foaming, may make some types of flow
meters unusable. Consider the characteristics of the wastewater when selecting flow
measurement instruments.

Installation of flow meters should allow for future plant expansions or changes in operation
which may affect monitoring points.

Flow meters should be installed downstream of any existing pretreatment facilities or
downstream from the location of any future pretreatment facilities.

APPENDIX B
SAMPLING
The following information should be useful in planning your wastewater sampling effort.
However, before proceeding, you must determine if your industry uses "batch" or "continuous"
wastewater discharges. If you are unsure of what these terms mean please refer to the discussion
in Appendix A.
Where is sampling required?
The points where samples will be collected must be shown on the schematic diagram in
Attachment 2 and are also listed in Sections 4 and 5 of the Baseline Monitoring Report form.
Samples from batch processes are collected directly from the tank containing the liquid to be
discharged. This sample must be representative of the wastewater just before it would be
discharged. Wastestreams from continuous processes should be sampled at the point(s) shown
in Attachment 2.
Sample Collection Types

A "grab" sample is defined as an individual sample collected over a period of time not to
exceed 15 minutes and collected so as to be representative of the wastewater at the
moment of sampling and of the parameter being monitored.

A "time composite" sample is defined as a single sample composited from a minimum of
four (4) grab samples of equal volume, collected at equally spaced intervals over a 24 hour
period of discharge, or a minimum of four successive samples collected over a 24 hour
period of discharge by an automatic sampler set in the time-proportioned mode.

A "flow composite" sample is defined as a single sample composited from a minimum of
four (4) grab samples collected at equally spaced intervals over a 24 hour period of
discharge and proportioned according to flow, or a minimum of four successive samples
collected over a 24 hour period of discharge by an automatic sampler set in the flowproportioned mode and run in conjunction with a continuously monitoring flow meter.

For continuous process discharges only, a "cyanide" sample is defined as a single sample
composited from a minimum of four (4) grab samples of equal volume collected at equal
intervals over a 24 hour period of discharge. Each grab sample must be preserved
according to 40 CFR 136 (see Appendix C).

pH samples must be analyzed in the field or by a qualified laboratory within 15 minutes of
the time of sample collection.
What type and how many samples must be collected?
BATCH: The following samples must be collected from each batch process discharge:
Page 14

One sample for the organic pollutants listed in Appendix D, reasonably expected to be present
in the discharge. A list of pollutants “reasonably expected to be present,” and the supporting
documentation for the determination (e.g., material inventory, engineering study, process mass
balance, etc.) must be submitted to the Metro District for approval. Otherwise, one sample
must be collected for all the organic pollutants listed in Appendix D.

an
Appendix
What analyses are needed?
The chemical analyses which must be performed on the samples are shown in Section 6 of the
BMR form.
How will the samples be collected?
There are three issues to be considered: (1) Should manual or automated sample collection be
used? (2) What type of sampling equipment is needed? (3) How do you sample for total toxic
organics (TTOs)?
1)
The sewerage agency does not care if you collect the samples manually or use automated
sampling equipment. Manual sampling of continuous flows will generally require an
individual to spend much of his or her time collecting samples and making flow
measurements. Automated sampling requires more money for purchase or rental of the
equipment but, once installed, will use less manpower. In making the choice between
manual and automated methods, you should be aware that, in the future, your company will
probably be issued a wastewater contribution permit which will require you to perform
sampling and flow measurement on a regular basis. Thus, over the long-term, automated
sampling may be less expensive and less labor-intensive than manual sampling. In
addition, many analytical laboratories and consultants also perform automatic sampling as
a part of their services.
Page 15
2)
Grab sampling requires little equipment. Generally a ladle made of stainless steel, "hard"
plastic, or glass can be used to collect samples. Automated sampling equipment is sold by
a number of local distributors. Keep in mind that automated sampling equipment and
automated flow measuring devices must be compatible.
3)
The specialized sampling techniques required for total toxic organics (TTOs) are discussed
in Appendix D.

APPENDIX D
SAMPLE COLLECTION PROCEDURES
FOR TOTAL TOXIC ORGANICS (TTOs)
and
LIST OF TTOs
Collecting wastewater samples for total toxic organic (TTO) analyses requires the use of sampling
techniques different from those normally acceptable for other types of wastewater samples. This
is because:

TTO analysis is done at much greater sensitivity than most other analyses. When looking
for toxic organics, we are looking at concentrations 100 to 1000 times less than most other
pollutants.

Materials commonly used for sampling and the cleaning of equipment, such as distilled
water and cleaning solvents, contain organic materials which can contaminate the sample.

Certain toxic organics are extremely volatile and will be lost or inadvertently added if the
sample is incorrectly collected or stored.

The high cost of analysis makes resampling expensive.
Before collecting any samples for TTO analysis, you must first identify a laboratory to do
the analyses. Because the laboratory must process the samples immediately, you may
have to adjust your sampling schedule to a time suitable to the laboratory. The laboratory
which agrees to do your analyses can also supply you with the specially prepared sample
bottles needed to collect TTOs.
The following points must be kept in mind when collecting samples for TTO analyses:

Don’t rinse or open the bottles prior to sample collection. Rinsing them or needlessly exposing
them to air may contaminate them.

Don’t use plastic or Tygon materials to do your sampling. Most automatic sampling equipment
contain these materials and should not be used. Specially designed automatic sampling
equipment constructed with Teflon tubing, glass, and stainless steel parts are available for use
in sampling for organics. Manual sampling can be done using glass or stainless steel
containers.

For continuously discharging processes, a minimum of four grab samples must be collected for
each type of organic sample (volatile and non-volatile). These samples shall be collected at
equally spaced intervals over the period of discharge. For batch processes or where 24-hour
sampling is not feasible, a single grab sample representative of the wastewater just before
discharge should be taken.
Two types of bottles are required to collect samples for TTO analysis. Manual grab samples to be
analyzed for volatile organics (VOA) are generally collected in small vials. These vials have a
Page 18
screw cap with an often loose, Teflon liner. These bottles must be filled manually, in a manner
that prevents air bubbles from passing through the sample as the bottle is being filled. Once filled
and sealed, no air or air bubbles should remain in the bottle.
The best way to collect a sample manually, without air bubbles, is to: (1) fill the sample bottle to
overflowing by submerging the bottle, (2) slowly raise the bottle straight up so as to retain a dome
of liquid (convex meniscus) atop the bottle, and (3) while holding the bottle straight up, slowly
screw on the cap with its Teflon liner. Inverting the sealed bottle and tapping its side will indicate if
any air bubbles are present.
If more than one manual grab is collected, portions of the VOA vials cannot be mixed to do
compositing (flow or time). The whole vial of solution must be used. A flow proportioned VOA
sample is obtained based on the flow throughout the day. For example, a new vial would be filled
every time 500 gallons of process wastewater had discharged to the sanitary sewer. A time
proportioned VOA sample is collected at equally spaced intervals over the period of discharge.
After proper collection (flow or time proportioned) of the VOA sample, the vials must be taken to a
laboratory for compositing the individual samples into a single sample. Do not attempt to
composite VOA samples yourself. Alternately, each VOA sample may be analyzed separately and
the results reported as an arithmetic mean (i.e., a single value, just as for a composited VOA
sample).
Non-volatile organics are also collected in specially prepared bottles. However, larger bottles are
used (one to two liter capacity), and some head space should be left in the bottle. Samples to be
analyzed for non-volatile organics can be collected like any other composite (flow or time) sample,
keeping the previously mentioned points for TTO sampling in mind.
The samples must be kept cooled to 4°C after sampling using an ice water bath. During storage
and shipment, the samples should be maintained at 4°C. The screw caps must be retightened
after the samples are chilled to prevent leaking.
