1.1 General Purpose
The CrystalStream storm water treatment device is designed to treat the gross pollutants found in
urban storm water run-off and protect downstream waterways from these pollutants.
Additionally the CrystalStream unit provides spill protection for oil and other hydrocarbon
products.
1.2 Unit Description
The base unit is a pre -cast concrete rectangular structure constructed in various dimensions based
on the model purchased. The base unit is poured with walls of 6" reinforced concrete tested to
4,000 psi. A riser of the same construction is used if needed to bring the top of the unit to grade.
The internal components will vary based on the application and pollutants targeted. At most the
unit will have components consisting of a trash basket, mesh lining, baffles, oil & hydrocarbon
reservoir, adjustable weir plate and fiber mesh screen. All of these components are constructed
out of aluminum. The fiber mesh screen itself is coconut fiber. The internal placement of the
components will vary based on the individual nature of the site and hydrology but the basic
configuration is shown on the cover of this manual. This is also a standard cut sheet drawing
included in Appendix 1. The top of the unit can be either a tread plate double access lid or
aluminum hatch in non -traffic applications or a standard grate and frame/ring and cover in traffic
areas.
1.3 Unit Operation
The unit is installed with all components in place to operate and based on proper installation; the
owner has no responsibilities to make the unit operational. Due to the nature of construction
THE UNIT MUST BE INSPECTED WHEN THE SITE IS TURNED OVER TO THE
OWNER/END-USEk. (See Section 3.1 through Section 3.3 for inspections) IF IT IS NOT
CLEAN AT THAT TIME, IT MUST BE CLEANED AND LEFT UNDAMAGED AND
READY TO OPERATE. (See Section 4.1 for cleaning.) Please read this entire manual before
any inspection or cleaning operations. Your personal safety is important. Cali CrystalStream at
1-800-748-6945 if you are unsure about any procedure.
Prior to the site being turned over to the owner, CrystalStream Technologies recommends that
the pipe system leading to the unit be flushed and jetted, to make certain that any residual
sediment is cleaned from the pipes. When sediment is allowed to accumulate in the pipes, it
slowly moves to the unit during rainfall events. The larger the rainfall event, the more sediment
is moved. The CrystalStream storm water treatment device is extremely effective at trapping
sediment. When sediment is left in the pipes and moves to the unit, it can necessitate a shorter
than average cleaning schedule which translates into higher cleaning costs for the owner.
Cleaning and jetting the pipes assures the owner that the unit he receives is in proper working
order, and free of sediment. if the site is under a maintenance agreement with CST, CST
personnel will inspect the unit and the pipe system prior to the unit being transferred to the
owner.

1.4 Installation
The unit is installed during the construction phase with the excavation, pipe attachment, and
baekfill completed by the contractor on site. A stable roadway must be provided for delivery of
the CrystalStream unit. CrystalStream Technologies (CST) will provide the contractor with the
measurements he will need to excavate the hole. A 6" depth of crushed stone should be placed
under the unit to assist in leveling and to provide uniform base support. CST will have the unit
delivered to the site and placed in the hole with our equipment in most cases. After placement,
the contractor will backiill the device as necessary and attach the pipes. Proper construction
methods during the baekfill and pipe attachment are essential to the operation and cleaning of the
CrystalStream unit.
Contractors Please Note:
Call CrystalStream at 1-800-748-6945 if you are unsure about any procedure.
• The pipes must be placed at the correct invert for the unit to achieve the proper removal rates.
• The pipes must be installed flush with the interior walls of the unit to provide for proper
cleaning access.
• The pipes must be mudded in on both the inlet and outlet connections. Failure to properly
mud the pipes can result in the water undermining the soil surrounding the unit.
• When a tread Plate lid is used on the Model 646, CST also provides a set of hooks to be used
to hold the lids open during maintenance and cleaning procedures except in traffic areas.
These hooks should also be turned over to the property owner when all construction has been
completed.
• A stable roadway must be maintained to facilitate inspection and cleaning of this unit. This
roadway must be, at a minimum, constructed of gravel or crushed stone on a stable base, and
must be capable of supporting a cleaning truck weight of approximately 15,000 pounds.

CST Installation, Operation, Inspection, Cleaning and Maintenance Manual - V 1.1 - 2I-Ian-05
2.1 Safety Overview
The CrystalStream unit is designed to be cleaned and maintained in an efficient safe manner by
qualified professionals trained to service in -ground vaults and to handle the equipment necessary
for removing the pollutants targeted.
The CrystalStream unit can be cleaned using common equipment and methods including
cleaning from the surface using a vacuum truck and trash netting system. Although this method
will be addressed, in our experience with these types of devices, a confined space entry cleaning
yields a quicker, more thorough and less cost intensive result.
This manual is intended to explain the specifics of our system, and to review the common aspecls
of the existing regulations and safety procedures, It is the responsibility of all personnel to
familiarize themselves with, understand, and comply with all applicable local, state and federal
laws, before attempting to inspect, maintain, or clean the CrystalStream unit.
ALWAYS FOLLOW ALL OSHA REQUIREMENTS WHEN ENTERING A CONFINED
SPACE. CRYSTALSTREAM TECHNOLOGIES RECOMMENDS THAT CLEANING
BE ACCOMPLISHED BY A "BUDDY SYSTEM" AND THAT BOTH WORKMEN BE
CONFINED SPACE ENTRY RESCUE AND CONFINED SPACE AWARENESS
TRAINED.
CAUTION! Any inspection or maintenance work performed in a traffic area must meet
the DOT guidelines for roadway work and additional safety procedure will be necessary.
2.2 OSHA Requirements
Definition of A Confined space
A confined space has limited or restricted means of entry or exit. It is large enough for an
employee to enter and perform assigned work. The confined space is not designed for
continuous occupancy. Confined space openings are limited primarily by size or location. The
atmosphere in a confined space may be hazardous due to low oxygen levels, flammable or
explosive concentrations of gases, vapors or dusts, or toxic levels of gases and vapors.
NOTE: Never enter a CrystalStream unit when there has been an obvious gasoline spill or
other flammable/hazardous material. This manual is for routine cleaning of storm
water:debris and any unusual occurrences should be left to properly trained and
equipped individuals.

Book 1174. Paae 884. File Number

(Page 11 of 23)
CST Installation, operation, Inspection, Cleaning and Maintenance Manual - V !.I - 2)-Jan-05
Entry without hermit/attendant
Confined spaces may be entered without the need for a written permit or attendant provided that
the space can be maintained in a safe condition for entry by mechanical ventilation alone. All
spaces shall be considered permit -required confined spaces until the pre -entry procedures
demonstrate otherwise. Any employee required or permitted to pre -check or enter an
enclose d/eonfined space shall have successfully completed, as a minimum, the training as
required.
Testing the Atmosphere
Before entering a confined space, testing should be completed for oxygen, then for flammable or
combustible gases and vapors and finally for toxic gases and vapors. Some gases and vapors are
heavier than air and will settle to the bottom of a confined space. Other gases are lighter than air
and will be found around the top of the confined space. Testing should be done in all areas (top,
middle, bottom) with testing instruments that are calibrated in accordance with the
manufacturer's recommendations to detennine what atmospheric conditions are present.
NOTE: The test for oxygen is performed first because most combustible gas meters are
oxygen dependent and will not provide reliable reading in an oxygen deficient
atmosphere. Testing for combustible gases are tested for next because the threat
of fire or explosion is both more immediate and more life threatening than
exposure to toxic gases and vapors. If testing reveals oxygen deficiency or the
presence of toxic gases or vapors, the space must be ventilated and retested before
the worker may enter.
Detector tubes, alarm only gas monitors and explosion meters are examples of monitoring
equipment that may be used. I£ there are no non -atmospheric hazards present and if the pre -entry
tests show there are no dangerous air contamination and/or oxygen deficiency within the space
and there is no reason to believe that any is likely to develop, entry into and work within may
proceed.
Ventilation
Ventilation by a blower or fan may be necessary to remove harmful gases and vapors from a
confined space. We recommend that a ventilating hose run to the bottom of the unit to blow out
all harmful gases or vapors. The air intake should be place in an area that will draw in fresh air
only. Ventilation should be continuous where possible because in many confined spaces the
hazardous atmosphere will accumulate again when the flow of air is stopped. Periodic testing
must be conducted to ensure that the atmosphere inside the confined space is safe.

CST Installation, Operation, Inspection, Cleaning and Maintenance Manual - Vt.] - 21-Jan-05
Respirators
Respirators are devices that protect workers from breathing unsafe levels of toxic particles, gases
and vapors. Two basic types of respirators are air purifying, which filter dangerous substances
from the air and air —supplying which deliver a supply of safe breathing air from a tank or an
uncontaminated area nearby.
Manholes
CrystalStream devices located in traffic areas use a manhole as the point of entry into the unit.
Manholes may present a variety of hazards if proper care is not taken. When covers are removed
manholes can become a trap into which workers can fall, It can also become a hazard to others if
the manhole cover is not replaced when the work has been completed
2.3 Inspection Safety
Always place cones around the CrystalStream unit and the vehicle to keep people out of the
working zone.
In traffic areas, follow all DOT regulations for roadwork.
Follow all OSHA requirements if entering the unit.
The tread plate lids can be very heavy, Follow appropriate safety measures when lifting the lid to
avoid back injury.
Remember, snakes and other creatures like dark, cool spaces. Use appropriate caution to remove
creatures from the unit.
Always lock all non -traffic lids, using the locking bar and locks provided.
Always replace the manhole cover and the metal grating when completing the inspection.
Follow all procedures outlined in Section 3.2.
2.4 Cleaning & Maintenance Safety
Always place cones around the CrystalStream unit and the vehicle to keep people out of the
working zone.
In traffic areas, follow all DOT regulations for roadwork.
Follow all OSHA requirements if entering the unit.

2.5 Public Safety
Before inspecting or cleaning the unit, clear the zone of unnecessary personnel. Put up cones
and warning tape to keep people out of the working area. Use of physical barriers is important to
protect both the workers and the public from injury.
Follow all Department of Transportation requirements when working in traffic areas. Consult
your local DOT guidelines to determine what precautions are required.
Always replace the manhole cover when inspection or maintenance is performed on the
CrystalStream unit with a traffic lid.
3.1 Inspection Overview
The unit is designed and specified in most applications to comply with the non -point source
mandates of the Clean Water Act and the NPDES regulations. These regulations state that any
BMP (Best Management Practice) needs to be inspected every 90 days and cleaned and
maintained as needed. Many local regulations have similar requirements and all federal, state
and local requirements must be met. CrystalStream Technologies recommends visual inspection
on a 30-day cycle as well as sediment depth inspection, during the construction phase. The unit
inspection is done to determine the operational status of the unit and determine if a cleaning
cycle is necessary as well as to meet any jurisdictional ordinance requirements. All inspections
must be documented (Appendix 2). When construction has been completed and the site has
stabilized, the CST unit should be inspected every 90 days and cleaned when there is I" of
sediment in front of the oil reservoir.

CST Installation, Operation, Inspection, Cleaning and Maintenance Manual - V 1.1 -21-Jan-05
3.2 Inspection Procedures
As per the following:
3.2.1 The unit should be visually inspected from the surface to determine the integrity of
access points. Look for broken hinges or broken or missing handles. A qualified
welder should repair any broken hinges immediately. Inspect bolts on lid angle iron
and look for loose red heads on angle iron. Replace red heads as needed. Re -paint the
lid, with a rust resistant paint as necessary.
3.2.2 The access should be opened and secured properly.
3.2.3 A visual inspection should be made of the trash basket at the front of the unit to
determine capacity and type of material trapped.
3.2.4 A visual inspection should be made of the water surface in the front of the unit to
determine oil sheen or blanket.
3.2.5 A visual inspection should be made of the oil and hydrocarbon reservoir to determine
amount of oil/water trapped and the historical high-water level in the unit.
3.2.6 A visual inspection of the water surface in the rear of the unit should be made and any
pollutants noted.
3.2.7 Inspect the aluminum mesh in the trash basket. Replace as needed.
3.2.8 Inspect the basket frame for cracks or damage. Repair as needed.
A visual inspection should be made of the pipe connections to the unit and any material
decay or improper installation noted. Pipes should be cut flush with the interior wall of
the unit and properly mudded in. If upon inspection it is noted that the pipes are not
cut flush, or are not mudded in, contact the contractor and require that he correct
this immediately.
3.2.9 Inspect baffles to ensure that they are properly seated into the brackets. Also note if
there is any damage to baffles (bowing). Reseat baffles if necessary.
3.2.10 Inspect oil reservoir for cracks or damage. Check the welds around the oil reservoir for
wear or damage and note any repair work necessary. A qualified welder must perform
all repair work to the welds on the oil reservoir during the routine cleaning.
3.2.11 Inspect the riser for cracks in the concrete walls. Repair as required during the routine
cleaning.
3.2.12 A silt gauge should be used to determine sediment depth as shown in Appendix 1.
Check the silt/sediment level behind the trash basket and in front of the oil reservoir
3.2.13 The access for cleaning should be evaluated and documented. The truck cleaning these
units requires a stable roadway capable of withstanding 15,000 pounds.
3.2.14 Any changes in the area tributary that are evident should be noted.
3.2.15 Replace the access point covers carefully.
3.2. l6 Note the condition of the area surrounding the unit on the inspection report. (Example:
grass, dirt, rocks, sink holes) Report any hazardous conditions to the appropriate
supervisor.
3.2.17 An inspection report should be completed, with a copy staying on site and a copy being
sent to the local jurisdiction.

CST Installation, Operation, Inspection, Cleaning and Maintenance Manual - V 1.1 - 21-lan•05
The inspection procedures for the traffic units are similar to those for the non- traffic units with
the exception of the sediment depth evaluations as shown in Appendix 1 and an inspection of the
grate and Frame and Ring and Cover. Also proper precautions should be taken in Traffic
situations as specified in the Safety section of this manual.
NOTE: When there has been an obvious gasoline spill or other flammable/hazardous
material in the unit, immediate notification should be given to the owner and
jurisdictional authorities. This manual is for routine cleaning of storm water
debris and any unusual occurrences should be left to properly trained and
equipped individuals.
4.1 Cleanine Overview
The cleaning of the unit is the essential element to the operational success of the CrystalStream
Device. The pollutant removal capacity of the device will eventually cause the equipment to fail
without proper maintenance and additionally not achieve the goals of the installation. The
cleaning cycle is dependant on a number of factors including pollutant load, rainfall, time of
year, basin changes, upstream mitigation tactics and installation. Based on the variety of factors,
a cleaning schedule can be consistent or vary widely on the same device. This highlights the
importance of the inspection process in the overall maintenance and integrity of the unit. The
cleaning is generally done with a two -person crew and a vacuum pump system. The duration of
the maintenance will depend on a number of factors but can typically be done in about 2.5 hours
with properly trained individuals.
4.2 Cleanina Procedures — Surface Cleanin
If the cleaning of the unit is to be preformed from the surface, the operator should expect a
longer cleaning time and the potential for additional disposal charges. The front chamber of the
unit will contain the trash and debris in the trash basket, any floating hydrocarbons that have not
been skimmed into the oil/hydrocarbon reservoir and accumulated sediment on the bottom of the
unit.
Cleaning procedures are as per the following:
4.2.1 The unit should be visually inspected from the surface to determine the integrity of the
tread plate lid, Aluminum Hatch or other access.
4.2.2 A visual inspection of the unit should be done to evaluate structural integrity and
determine if any impacted material is present in the device. If there has been a
hazardous spill see Section 4.6
NOTE: When there has been an obvious gasoline spill or other flammablethazardous material in
the unit, immediate notification should be given to the owner and jurisdictional authorities. This
manual is for routine cleaning of storm water debris and any unusual occurrences should be left
to properly trained and equipped individuals.

4.2.3 The Trash Basket should be cleaned by either using a trash netting system or vacuum
truck. If cleaning using a netting system, this material can be disposed of in trash bags
in the normal manner.
4.2.4 The surface oil/hydrocarbon separation zone in the front chamber should be removed
either with sorbants or with a vacuum truck,
4.2.5 The stormwater contained in the area between the surface water and the sediment
accumulation can be decanted to minimize the amount of disposal required. Any
downstream discharge needs to be after the surface cleaning and only down to the level
of the bottom of the oil/hydrocarbon reservoir or the top of the sediment accumulation,
Any pollutants discharged downstream are the responsibility of the cleaning operator.
4.2.6 The oil/hydrocarbon reservoir needs to be evacuated by the vacuum equipment.
4.2.7 The sediment accumulated in the front and rear chamber can be removed by the
vacuum equipment.
4.2.8 The unit should be pressure washed down to remove any pollution attached to the
baffles, walls or hydrocarbon reservoir.
4.2.9 All parts should be inspected for wear and tear and documented.
4.2.10 A maintenance report (Appendix 3) should be completed, with a copy staying on site
and a copy being sent to the local jurisdiction.
4.3 Cleaning Procedures — Confined Space Entry
The cleaning procedures are similar for confined space entries except that the OSHA guideline
apply and need to be followed. The confined space entry allows the crew to do a better job of
cleaning the unit and allows for the time needed and disposal cost to be reduced.
CAUTION! Any inspection done in a traffic area must meet the DOT guidelines for
roadway work and additional safety procedure will be necessary.
CAUTION! All OSHA confined space requirements should be met while cleaning this unit.
4.3.1 The unit should be visually inspected from the surface to determine the integrity of the
tread plate lid.
4.3.2 A visual inspection of the unit should be done to evaluate structural integrity and
determine if any impacted material is present in the device. If there has been a
hazardous spill see section 4.6

material in the unit, immediate notification should be given to the owner and
jurisdictional authorities. This manual is for routine cleaning of storm water
debris and any unusual occurrences should be left to properly trained and
equipped individuals.
4.3.3 A ladder should be inserted on the front side of the unit between the baffles and a
sorbant blanket laid on the surface of the water to collect any free oil floating on the
surface.
4.3.4 In most units, the trash basket and baffles can be removed to allow easier access
to the bottom of the unit.
4.3.5 Inspect the aluminum mesh in the trash basket. Replace as needed.
4.3.6 The Trash Basket should be cleaned and directly disposed of in garbage bags.
4.3.7 The stormwater contained in the area between the surface water and the sediment
accumulation can be decanted to minimize the amount of disposal required. Any
downstream discharge needs to be after the surface cleaning and only down to the level
of the bottom of the oil/hydrocarbon reservoir or the top of the sediment accumulation.
Any pollutants discharged downstream are the responsibility of the cleaning operator.
4.3.8 The unit should be pressure washed down to remove any pollution attached to the
baffles, walls or hydrocarbon reservoir.
4.3.9 The ladder can be used to get on to the unit floor and remove the rest of the water and
sediment from the bottom of the unit.
4.3.10 The walls should be wiped down in the front with a sorbant blanket
4.3.1 l The fresh coconut fiber mesh should be replaced in the frame and the frame assembly
returned to the unit.
4.3.12 All parts should be inspected for wear and tear and documented.
4.3.13 Remove all equipment from the unit. Replace the manhole cover and the grate in the
concrete lid.
4.3.14 A maintenance report (Appendix 3) should be completed, with a copy staying on site
and a copy being sent to the local jurisdiction.
