This article is written from the stand point of what is economically
feasible for the Mobile Power Wash Contractor to implement in plain
English for the washing of items not contaminated by hazardous material.
This article does not include hazardous washing and cleaning.
-
Complying with Environmental Power Washing Regulations is fairly simple.
DISPOSE OF ALL OF YOUR WASH WATER TO SANITARY SEWER. The hard part comes
from all the variations in applying this simple procedure. No one answer
works in all locations, you will need a lot of tools and techniques you
can call on.

Environmental Power Washing
Environmental Power Washing is the proper environmental disposal of your
used wash water. Exactly what this is will be defined on a local basis,
usually by the Local Municipality. Mobile Power Wash Recycling is but one of
the many techniques used to meet this criteria.

THE EPA AND ENVIRONMENTAL COMPLIANCE
Off
property discharge of Vehicle Wash Water is a violation of the Clean Water
Act. Daily fines can be: Cities--$2,000.00 per day, States--$10,000.00 per
day, and the EPA--$25,000.00 per day. The American Trucking Association had
their first ever National Conference on Environmental Vehicle Washing April
6 & 7, 1995 in Fort Lauderdale, Florida. RAHSCO Cleaning Systems was a sponsor of that seminar.
-
The Environmental Protection Agency (EPA) does not provide written
endorsements of products, processes, or technology. The EPA
responsibilities are directed at setting specific objectives
(discharge limits) that dischargers must meet to adequately protect
receiving waters of the United States. These objectives will
necessarily vary from site to site.
-
So where does this leave the Mobile Power Wash Operator? Basically
it means that the City and County Governments deal with the EPA and
State Regulatory agencies with the discharge of their Sewer
Treatment Plants (POTWS) and Storm Water. And the Mobile Power Wash
Operators must deal with the City and County Governments. Each POTW
(Public Owned Treatment Works) must meet specific guidelines set by
the EPA. Also each City must meet specific discharge objectives for
their Storm Water runoff. The EPA does not specify how these
discharge objectives are going to be met. Each POTW or City can
decide what technology, products and procedures they are going to
use to meet the EPA Guidelines. This means that rules for
Environmental Power Washing will vary from City to City and
sometimes from site to site within the same city.
-
If Wash Water is recycled long enough it will test hazardous and
have to be disposed of at a hazardous waste facility and you may
have to obtain a Hazardous Waste Generator Permit. This is not
economically feasible. What is economically feasible is to recycle
the wash water for a short period to time and discharge it to the
sanitary sewer within sanitary sewer discharge limits. These limits
will vary from site to site. What most Environmental Mobile Wash
Operators are doing is limiting their washing activities so that
they do not enter the hazardous classifications. This is most
commonly done by limited their washing to cosmetic cleaning of
non-hazardous items. No degreasing, no two-step chemicals, no
Aluminum Brightening, and no battery washing as these items may
cause your heavy metals to exceed sanitary sewer limits and cause
your wash water to test hazardous.
-
What follows are the most popular Environmental Mobile Power Wash
Options as they are now being enforced and practiced today.
-
STORM WATER PERMITS
The
portion of the Clean Water Act that is effecting Mobile Power Washing the
most is the National Pollution Discharge Elimination Systems (NPDES) Permits
required by the EPA for Storm Water runoff. NPDES Permits are basically
storm water management plans. The NPDES Permits effecting Mobile Power
Washing are the ones required for States, Cities, and Fleet Owners. These
permits require the cleaning up of Rain Water and Snow Water runoff into our
lakes and streams. This includes the elimination of pollution from washing
operations entering our lakes and streams carried by Storm Water runoff.
-
Phase I of the EPAs NPDES Permits for cities over 250,000
population were due November 16, 1992, and for cities over 100,000
population were due May 17, 1993. The NPDES Permits for fleet owners
were due October 1, 1993. These permits included procedures of how
wash water was to be disposed of. The cities were basically given
two options to come into compliance with their discharge limits.
They can collect and treat all of their sanitary and storm water or
they could go to the source of the pollution and control the
discharge, like Mobile Power Washing. This is the most popular
option and it means that wash water will have to be discharged to
sanitary sewer. A major part of the Phase I permits is public
education for these cities. The most visible part of the Public
Education Program is Environmental Inserts and Advertising Space in
local News Papers giving Home Owners hints for better Environmental
Management. This literature almost always includes phone numbers of
the local Environmental Regulators.

Phase II of the EPAs NPDES Permits for cities under 100,000 has
been extended by the EPA until August 2, 2001. Therefore, in cities
under 100,000 population the main environmental pressure will be
from your customers with Environmental Departments.
The
American Trucking Association had their first ever National Conference on
Environmental Vehicle Washing April 6, & 7, 1995 in Fort Lauderdale,
Florida. RAHSCO Cleaning of Fort Worth was a sponsor of that seminar. There
were over 180 people in attendance, and some of the companies represented
were: Adams Motor Express, Allwaste Container Services, Anderson Concrete
Corporation, Alterman Transport Lines, Blue Shores Distributing, Buffalo
Fuel Corporation, Catwba Rental Company, City of Delray Beach, Commercial
Carrier Corporation, Contractors Chemical Corporation, Dana Container, Deans
Foods Company, DSI Transport, Federal Express, Florida Power and Light,
Florida Transport Company, Stoops Freightliner, Gator Leasing, General
Parcel Service, Gold Kist Incorporated, R. O. Harrell Incorporated, Hogan

Transport Incorporated, SuperValu, Texas Instruments, Texo Corporation,
Transport International Pool, Union Pacific Properties, United Parcel
Service, UPS Truck Leasing, US Army Reserve Command, US Postal Service,
Victory Express, Watkins Motor Lines, and Yellow Freight Systems. All of
these companies are in the process of implementing Environmental Correct
Vehicle Washing Procedures. And companies that are utilizing the services of
Contract Cleaners are going to require that Environmental Correct Vehicle
Washing Procedures be used!
What
happened in Fort Worth, Texas is typical across the Nation. In 1993 the
Department of Environmental Management tested over 560 storm water sites
within the city of Fort Worth. Detergent was discovered in over 50% of these
sites making detergent the most encountered pollutant in the City. It was
determined that cosmetic cleaning was a significant source of these
detergents. The EPA is giving the City of Fort Worth five (5) years starting
in 1996 to show a decrease in the pollutants at the 560 sites. If the city
does not clean up its storm water the EPA may require a treatment plant to
be constructed at the cost of several hundred million dollars similar to the
Sewer Treatment Plant to treat all of the storm water. Therefore, starting
in January 2, 1996 all of Mobile Power Wash Operators will have to be
license in the City of Fort Worth. This license will include a permit to
discharge to the sanitary Sewer for cosmetic cleaning of un-concentrated
wash water.
-
NO
OFF PROPERTY DISCHARGE
-
No off Property Discharge is the most popular Environmental Power
Washing Option today. No problems exists if no wash water leaves the
property where the washing is accomplished. However, there are some
potential risks with this procedure. They are: 1) when the property
is sold a soil test may be required and remediation can be extremely
expensive, or 2) the ground water may be contaminated and require
remediation, this hazard is very high in areas where the ground
water is close to the surface as in Miami, Florida.
-
A warning is normally given on the first offense to the either the
Contract Cleaner or the Customer. The 2nd or 3rd offense is normally
a fine of $800.00 to $1,200.00. Some cities will fine the companies
while other cities will fine the employees. A fine is not normally
given on the first offense because most cities are striving for
voluntary compliance.
-
Some areas are allowing 1 to 8 vehicles to be washed on grassy areas
and depend on nature to remediate the wash water.
Uncontrolled vehicle washing is presently being permitted in Arizona and
Iowa. This is for cosmetic washing with biodegradable detergents. Contact
Representative for Arizona is Bill Engstrom at 602-207-4696 and for Iowa is
Steve Williams at 515-281-8884. While these two states may have decided not
to regulate Mobile Power Washing at this time the individual Cities may in
fact do so!
-
SEWER TYPE
-
There are basically three types of sewers, they are: Sanitary,
Storm, and Combined. Most cities have a Sanitary and a Storm Sewer
System. The Sanitary Sewer System is what your home sewer is hooked
up to. This system of pipes goes to the sewer treatment plant or
Public Owned Treatment Works (POTW). At the POTW the sewage is
treated and discharged to lakes or streams. This is where your wash
water needs to go for treatment before being discharged to lakes and
streams.
The
Storm Sewer is where the rain water goes in to gutters along the streets and
roads. This water is generally discharged directly to lakes and streams
without treatment. Because this water is not remediated before discharge
into the environment you should not discharge your wash water to a storm
sewer.
-
Some cities have a combined sewer system where the sanitary and
storm sewer are one system and all of the sewage and storm water are
treated at the POTW. In these areas the wash water can be discharged
to storm sewer. You will need to call the Sewer Department in each
area you are washing in to determine which system you are
discharging to.
-
Most outside drains are storm sewers and most inside drains are
sanitary sewer drains but not always. Be sure to know which is
which. If your customer does not know call the Sanitary Sewer
Department you are hooked to and they will come out and determine
which sewer system each drain is hooked to. In many areas this
service is free.
-
The capacity and capability of POTWS vary greatly and so do their
discharge limits. Discharge limits are determined by many factors
including: the size of the body of water they are discharging to
such as a lake, river, stream or ocean, what they are discharging,
and the amount they are discharging. The larger the body of water
the more relaxed are the discharge limits. Because discharge limits
and POTW treatment abilities vary the amount of treatment wash water
needs before being discharged to sanitary sewer also will vary from
POTW to POTW.
-
WASH AREA
-
The easiest way to go to sanitary sewer is to wash in the customers
wash bay or pump your wash water to the wash bay sand trap
(Clarifier, Oil/Water Separator, or Restaurant Grease Trap). Some
Cities will allow you to wash on a hard surface and pump the wash
water to the sand trap. Other cities will not. Their reasoning for
this is that they do not feel that the contractor will clean up all
of the contaminates after he has finished his washing. And that when
it rains all of the contaminates will be washed into the Storm Sewer
drain.
-
In cities that do not allow washing on a hard surface you will
either have to wash on a portable vinyl wash pit or in a designated
area that has been bermed up to contain the wash water. Some cities
will not allow washing on asphalt as your detergents will attach
this surface. Asphalt is basically hydrocarbons and detergents are
designed to attack hydrocarbons.
-
DISPOSAL OF WASH WATER TO SANITARY SEWER
-
Since the discharge limits of POTWS vary so greatly so do the
methods of discharge to them. Some POTW will accept wash water
without any pretreatment or very little pretreatment, like filtering
out the sand. Some POTWS for cosmetic cleaning require only
filtering with a 200 micron dirt and sand filter or a carbon filter.
What POTWS will want to know is how much wash water you will be
discharging and what contaminates will be in the water. A water
analysis is generally required, this costs $200 to $400 and some
POTW will do this test for free. Some POTWS will accept the wash
water without any analysis and require an analysis only if a problem
arises.
-
A common method for discharging is to sand traps (Clarifier,
Coalescer, Oil/Water Separator, or Restaurant Grease Trap) located
at Truck Washes, Coin-op Car Washes, and Restaurants. The problem
with this is that most cities do not want you taking your wash water
from the location where it was generated and disposing of it at
another location. This is because if a problem arises there is not a
clear path of whose fault it is. Most cities want the water
discharged where it was generated in order to cover liability. If
there is not a sand trap on location the wash water will probably
have to be pretreated before being discharged to a sanitary sewer.
Another problem is that there are no rules that clearly define the
transportation of wash water from site to site. Sometimes the cities
try to classify wash water in the same category as sand trap (grit
trap) services. But you are not cleaning out or hauling sand trap
contaminates. And wash water almost always tests non-hazardous. Also
wash water is considered SPECIAL WASTE by the EPA. This is a
different category than sand trap containment. Caution: do not
discharge to a sand trap without first getting written permission of
the owner of the sand trap.
-
A misconception is that biodegradable soaps can be discharged to
Storm Sewer. Biodegrading takes time and biodegradable detergents
may be quite toxic before they biodegrade. Also there is a problem
with what the soap emulsifies, like oils, greases, fats, dirt,
pesticides and insecticides And phosphates cause some POTW problems.
Phosphates cause a problem because they are good fertilizers and
cause algae growth which depletes the oxygen in the water killing
the fish. And of course fish kills are very visible with dead fish
floating on top of the water which attracts TV cameras which creates
the type of publicity you do not need! In some areas phosphate free
soaps are required.
-
Most POTWS will accept your waste directly. However, this creates an
economic problem with Commercial Waste Disposal Facilities. They
think you should bring your wash water to them. They see the POTWS
as a government organizations competing with them. They already have
a professional association representing them, so it comes down to
politics and political power. Basically, the Commercial Waste
Disposal Facilities will pass your waste on to the POTWS and charge
you a fee for this service.
-
In some areas Commercial Waste Disposal Facilities are your best
economic alternative. Their yellow pages heading is: WASTE
REDUCTION, DISPOSAL & RECYCLING SERVICE, INDUSTRIAL. Typical costs
for wastewater discharge range from 5 cents to 70 cents per gallon.
-
You will need to check with each POTW you are discharging to for
their discharge limits. Normally these discharge limits will fall
within these ranges: pH--(5 to 6) to (10 to 12); Fats, Oils, and
Greases (FOG) or Total Petroleum Hydrocarbons (TPH)--less than (100
to 400) milligrams per liter (mg/l); Total Suspended Solids
(TSS)--less than 200 mg\l to no limit; Biochemical Oxygen Demand
(BOD)--less than 200 mg/l to no limit; Chemical Oxygen Demand
(COD)--less than 450 mg/l to no limit. Heavy Metals Limit Ranges
are: Arsenic (As)--less than (0.05 to 0.1) mg/l; Barium (Ba)--less
than 5.0 mg/l; Boron (B)--less than 3.0 mg/l; Cadmium (Cd)--less
than (0.3 to 0.7) mg/l; Chromium (Cr)--less than 5.0 mg/l; Copper
(Cu)--less than (3.0 to 4.5) mg/l; Lead (Pb)--less than (0.1 to 2.9)
mg/l; Manganese (Mn)--less than 1.0 mg/l; Mercury (Hg)--less than
(0.005 to 0.01) mg/l; Nickel (Ni)--less than (1.0 to 2.0) mg/l;
Selenium (Se)--less than 0.4 mg/l; Silver (Ag)--less than (0.1 to
1.0) mg/l; and Zinc (Zn)--less than 5.0 mg/l. If your wash water is
outside the sanitary sewer discharge limits, you may still be able
to discharge to the sanitary sewer but have to pay a surcharge.
-
Some companies have gotten permits to discharge to Leech Fields,
Septic Tanks, and Injection Wells. Recently the Health Departments
in some areas have been going out and testing these sites. Depending
on what is found the companies may be required to stop using these
sites or remediate the discharge areas. The safest technique is to
discharge to Sanitary Sewer wherever possible.
-
Most POTWS do not require any pretreatment of the Wash Water when
discharging to the Sanitary Sewer through a Truck Wash or Car Wash
Bay as these sand traps are designed to for this purpose.
-
DISPOSAL OF WASH WATER TO STORM SEWER
-
Normally you should never dispose wash water to storm drain (note:
because so many people confuse the terms Sanitary Sewer and Storm
Sewer it recommended that the tem Storm Drain replace Storm
Sewer. In this document you will see both terms used. As a contract
cleaner you will need to be aware of this confusion.). However,
there are common exceptions to this rule. They are: washing one or
two vehicles on grassy areas occasionally, house washing and
building washing because it is rarely done, vehicles washing at
residences, and vehicle washing by charities.
-
Some Cities are allowing cold water washing with no chemicals (other
cities hot water washing with no chemicals where there is no oil and
grease, dirt only) to go into the storm sewer if these areas contain
no hydrocarbons, pesticides, insecticides, or antifreeze. Hot water
washing is considered to be PROCESSED WATER because hot water will
emulsify oil and greases. Cold water washing is considered no worse
than a rain event. The oil and grease spots should be pre-cleaned
with absorbent clay (kitty litter) and disposed of in the dumpster.
Leaves, debris, and dirt should be cleaned up before washing so this
contamination does not enter the storm sewer. Storm Sewer entrances
should be screened to catch leaves and debris and the wash water
should pass through an oil absorbent boom or pad to absorb the
hydrocarbons. No oil sheen should be present after passing through
the oil absorbent filter. No chemicals can be compensated for by
using a zero degree rotating nozzle such as a ST-58 Turbo Nozzle or
a Rotomax Zero Degree Rotating Nozzle. Typical washing examples are:
Vehicles on Dealer Lots (dust only), sidewalks, shopping malls,
parking lots, buildings, and homes.
-
Some cities will allow building washing with acid cleaners if the
acid is neutralized before entering the storm sewer. Typical
neutralization is with baking soda (sodium bicarbonate), soda ash
(sodium carbonate), or alkaline detergent wash such as R109, or DNB
1430 instead of a clear water rinse. In other cities the cleaning is
done with cold water , no chemicals, and rotating zero degree
nozzles such as the ST-58 Turbo Nozzle or the Rotomax.
-
RECYCLE WASH TECHNIQUES
Recycle Units clean the water only enough so that the water is suitable for
washing but not rinsing. Recycle Units that clean the water to rinse water
quality are too expensive for contract cleaners. Therefore, rinsing will
have to be done with fresh water. Normally recycle units do not remove
detergents, total dissolved solids, or heavy metals. This means that your
detergent usage will decrease, but it also means that if you recycle the
wash water long enough it will test hazardous and have to be disposed of at
a Hazardous Waste Facility and you may have to obtain a Hazardous Waste
Generator Permit. The trick is to recycle the wash water only long enough
that it is still within the discharge limits of the sanitary sewer and
before it tests hazardous. A popular technique of many Environmental Power
Wash Contractors is to limit their business to cosmetic cleaning of
nonhazardous items and not to do heavy degreasing, acid or two step washing,
heavy brushing, or aluminum brightening as these activities cause problems
with Heavy Metals, and Hydrocarbons. For cosmetic cleaning of nonhazardous
items you should be able to recycle for one or two days and still stay under
sanitary sewer discharge limits with filtration and absorption technologies.
Examples are: Vacuum Sludge Filtering Systems, and the Recycle 16.
-
Evaporation and drag off for fleet washing are normally 30 to 50
percent. This loss is made up with rinse water. Under good water
management practices your rinse water will not exceed your loss due
to evaporation and drag off. Water loss due to evaporation in doing
flat work is related to temperature and how far the water travels
over a hot concrete surface. Water loss will normally range from 20
to 60 percent.
-
As previously stated washing will have to be done with recycled
water with detergent in it because the Recycle Systems do not remove
the detergents.. The longer you use the wash water the harder it is
to rinse off even though you are using a fresh water rinse.
Therefore it is common for Contract Cleaners to use their recycle
units as pretreatment units for direct Sanitary Sewer discharge.
Another technique that has caused some problems is pre-spraying the
equipment with a heavy detergent then using a fresh water wash. This
technique over flows a recycle system with water. This procedure
will only work if you are using the Recycle Unit as a Pretreatment
Unit for direct discharge to the Sanitary Sewer. This also applies
for Heavy Degreasing, Two Step Chemical Washing, and Aluminum
Brightening.
-
SLUDGE DISPOSAL
-
The least expensive method of collecting your dirt, sand, and debris
is right off of your wash surface before entering your wash water
pumping equipment. A $20.00 shovel is an inexpensive method of
picking up dirt and debris. The lower the technology to collect the
sludge the less expensive it is. The cheapest place to collect dirt,
sand and sludge is right off the wash pad.
-
Sludge from non-hazardous washing operations falls under the broad
heading of SPECIAL WASTE, and will have to be handled according to
federal, state, and local regulations. These options should
generally meet these requirements:
-
A. Put in the customers sand trap if available. You should get
permission to follow this procedure.
-
B. Let the dirt, sand , and sludge dry and leave for the customer to
put in his dumpster. Presently landfills cannot accept liquid waste.
In Texas you can put 220 pounds of dry sludge in your dumpster per
month. Remember, if the customer is generating other special waste
the dirt and sludge will have to be added to this total. The
customer should get permission from their refuse company to follow
this procedure.
-
C. Put the sludge in a 55 gallon drum and have a licensed sand trap
service haul the sludge to a proper disposal site.
-
D. Let the customer haul his own sludge to a proper disposal site.
You cannot haul it for him unless you are licensed waste hauler. The
Waste Disposal site will manifest every load, and if the generator
of the waste and the hauler are not the same a registration waste
transporter number is required.
Note:
You can find Sand Trap, Grit Trap and Grease Trap Services under GREASE TRAP
and MUD TRAP SERVICE in the yellow pages.
-
HYDROCARBONS DISPOSAL (used oil)
-
The EPA has classified used oil (hydrocarbons) as non-hazardous if
it is destined for recycling, re-fining, reprocessing or burned for
energy recovery. Therefore, you should disposed of your used-oil in
the aforementioned manner. It should be noted that the states of
California, Arizona, Massachusetts, Minnesota, Missouri, New Jersey,
New York, Rhode Island, South Carolina and Vermont regulate used oil
as a hazardous waste. Also some states designate used oil as a
special waste and have rules more stringent than those of the EPA,
these are Arizona, Illinois, Maine, Michigan, Minnesota, Washington,
Wisconsin, and Wyoming. Also some counties have even more rules
concerning used oils.
-
For Mobile Power Washing that is limited to cosmetic cleaning of
vehicles and flat work there is very little hydrocarbons
accumulated. In fact the dirt and sludge will absorb almost all of
the free hydrocarbons.
-
In Texas waste oil spills of 9 gallons or more will require
reporting to the Texas Natural Resources Conservation Commission
(TNRCC). Therefore, leave the hydrocarbons with your customer or
only transport small quantities.
-
You will need to contact your local waste oil recycling company to
see what their requirements are for disposing of your waste oil.
Generally there will be an extra charge for oil with dirt, sand, and
water in it. Find these companies in your yellow pages under
OILS-RE-FINED and OILS-WASTE.
-
HAZARDOUS CLASSIFICATION
-
You may be challenged as to whether the sludge or wash water
generated is hazardous. Several contractors and American Trucking
Association Members have had to have this test done. The test
required is the TCLP test. To date all tests that RAHSCO Cleaning
Systems of Fort Worth has known about have resulted in non-hazardous
classification of wash water and waste for cosmetic washing.
-
The transportation of 1000 pounds of hazardous chemicals that some
contract cleaners use will require a commercial license with a
hazardous endorsement. Check with your DOT office to see
specifically how these rules will affect you in your location.
-
Several companies doing cosmetic washing have had a problem with
zinc causing hazardous classification. The zinc was not from their
washing operation but from the city inlet supply. Old galvanize
pipes were contaminating the water!
-
Remember, you are in the Environmental Business and this may cause
you to be inspected closer than normal. Old batteries, old tires, or
used oil may cause you to be classified as storing hazardous waste.
Be tidy, it best to keep your property cleaned up.
-
WASTE OWNERSHIP
Ownership of any Hazardous Waste and Special Waste that is regulated by
state or local agency is the generator of that waste. Presently this
ownership cannot be transferred under any circumstances. Therefore, your
customer owns the waste from your washing operations and he is responsible
for the waste forever. Your customer is still responsible for his waste even
after a licensed waste hauler picks it up. The waste generator is
responsible from cradle to grave under present law. This means that if the
licensed hauler illegally disposes of his waste he maybe liable for clean
up! Presently the only exception to this is in the state of Oregon where
ownership can be designated as either the Contract Cleaner or the Customer.
-
WASH WATER PROCESSING EQUIPMENT
There
are five distinct categories of Wash Water handling equipment, they are:
-
A.
Wash Water Haulers (WWH) This equipment simply picks up the wash water
and hauls it to a proper disposal site. Normally this consists of a sump
pump or wet/dry vacuum with a sump pump which pumps the water to a 500
to 2000 gallon holding tank for transportation to the disposal site.
-
B.
Direct Discharge Units (DDU) These units are sump pumps or wet/dry
vacuums with a sump pump which pumps the wash water directly to sanitary
sewer. Little or no pretreatment is done. Most systems will filter out
the leaves and debris before discharge to sanitary sewer. Examples are:
WPSP-25 wash pit sump pump, Wet/Dry Vac with a Sump Pump, and the VSF-8
Vacuum Sludge Filtering Systems.
-
C.
Pretreatment Units (PU) These units are designed to pre-treat your wash
water then discharge it to sanitary sewer. Examples are: VSF-8 Vacuum
Sludge Filtering Systems, Recycle 8A, Recycle 16, and the Model 2000
Recycle System.
-
D.
Limited Recycle Units (LRU) These units are designed to recycle your
wash water for a limited amount of time before discharging to sanitary
sewer. Generally they recycle your wash water from one to two days. The
longer the recycle time the more expensive the equipment. The technique
is to limit the recycle time so that the wash water is below the
discharge limits of the Sanitary Sewer. For cosmetic cleaning this is
usually 8 to 16 hours of recycle washing. Examples are: Recycle 8A,
Recycle 16, Model 2000, and The Recycle 1, 2, 3 Mobile Wash Rigs.
-
E.
Total Recycling Units (TRU) True Total Recycling Units, that produces
rinse water quality water are too expensive for normal mobile power wash
operations. These units are commercially profitable only in unusual
circumstances where the increased cost of operation can be passed along
to the customer.
-
F.
Water Control Devices (WCD) Water control devices are items that pick up
or control the flow of wash water so that wash water can be properly
disposed of, they are:
-
Sump pumps
-
wet/dry vacuums with internal sump pumps
-
Vacuum sludge filtering systems
-
Vacuum booms
-
Portable dams
-
drain covers
-
Portable Vinyl Wash Pits
-
Oil Absorbent Pillows, Booms and Pads
-
Storm Sewer Drain Screens

WHAT YOUR ENVIRONMENTAL POWER WASH CUSTOMER WILL REQUIRE
-
A. Letter of approval of your Environmental Power Wash Procedures
-
B Letter of Acceptance for your Environmental Wash Waste
-
Depending upon the sophistication of your customer, generally
the larger the customer the more knowledgeable they are, they
will require both a letter of approval of both your wash
procedures and a letter of acceptance for your waste. In most
large cities these letters can be obtained from the Storm Water
Department and the Sanitary Sewer Department. A lot of
municipalities have not yet issued this type of approval. But as
more customers are requiring these documents the municipalities
are doing them. It will be easier if you use one of our samples
showing them what some other city has done. Remember, if you are
the first one to approach the municipality you will have a
chance to set the standards in your area.
-
Mobile Power Wash Operators who are willing to invest time,
money , and equipment in order to offer Environmental Washing
Services and obtain the Certification letters from regulating
authorities are receiving a tremendous competitive advantage. It
is not unusual for these operators to double or triple their
business in a year. Their first advantage generally will be
increased enforcement of the Clean Water Act for no off property
discharge. Since they are the only one that has an approved
procedure guess who gets recommended. Of course this exclusive
position will only last until someone else gets approval, but by
that time you should have already established your reputation.
RAHSCO Cleaning Systems has helped many Contract
Cleaners in almost every state implement this process.
-
Some fleets have reverted back to unrestricted washing since the
Republicans have come to power. However, this has happened only
on an isolated basis. For the most part enforcement is
increasing in all cities over 100,000 population because their
NPDES Permits require it.
15.
RISK MANAGEMENT
-
If the Clean Water Act is enforced as it is written home owners will
no longer be able to wash their automobiles in front of their homes
and discharge their wash water to storm sewer. Of course the public
is not ready to pay this price to clean up the environment. However,
the coin-op car wash operators are pushing for this very thing to
happen because it will increase their business (revenue stream).
They have been successful in several areas in stopping the Boy
Scouts and Girl Scouts from their fund raising car wash activities
where the wash water was disposed of to the storm sewer.
As you
travel the nations Interstate Highways its obvious that the enforced speed
limit is not 55 MPH. The most enforced speed limit is 70 MPH. Rarely is a
traffic ticket given for under 70 MPH. But if you requested authorization to
drive 68 MPH you cannot get it. So we have a written speed limit and an
enforced speed limit. If you drive 68 MPH your risk of receiving a ticket is
minimal and a risk that most people are willing to take. Why is this
important to the Environmentally Correct Mobile Power Wash Operator? Because
a lot of what you will be doing will be risk management. The exact Mobile
Power Wash Procedures that satisfy the Clean Water Act are not clearly
defined and the procedures fall between the cracks of existing regulations.
You can find as many interpretations of the regulations as you can find
environmental regulators.
-
Presently a large number of Mobile Power Wash Operators have verbal
approval for: 1) Disposing of wash water at: Truck Washes, Coin-op
Car Washes, Their own sand traps, and POTWS; 2) Disposing of the
sludge at: the customers dumpster, in the customers sand trap, your
own sand trap; 3) washing on a concrete parking lot; and 4)
pre-treating your wash water and disposing it in the clean out trap.
This verbal approval is good until someone complains such as a
Coin-op Carwash Operator, Sand trap Service, Commercial Waste
Disposal facility, or a competitor. The reason they are complaining
is because you are effecting their revenue stream. Again it is
politics and political power. The Coin-op Carwash Operators and Sand
trap Services have Trade Groups representing them.
o
What
happens if you are cited for improper washing procedures and your competitor
is not? Normally this puts you at a competitive disadvantage with customers
who are not environmentally conscious. These customers will probably go with
the lowest bid. Environmentally correct washing is more expensive and puts
you at a competitive disadvantage. Many Mobile Power Wash Contractors have
been faced with this problem. Now they are in a position of not being able
to provide for their families because of an uneven playing field. This is
not an unusual situation and it is happening over and over again as
Environmentally Correct Washing Procedures are being implemented. Again you
are effecting the revenue stream. Because of this economic pressure it not
unusual for competitors to turn each other in for improper washing
procedures. Taking photographs, videotaping, and calling regulating
authorities about improper washing procedures by a competitor or customer is
not unusual. This will probably continue as long as there is such a wide
variation in interpretation and implementation of Environmental Washing
Procedures to satisfy the Clean Water Act.
16.
OPPORTUNITY SPEAKS, ARE YOU LISTENING?
This
State of Confusion spells opportunity for many contractors. Never again will
it be so easy to influence how the Clean Water Act will be implemented in
your area. Those contractors who are the first ones in their service areas
to offer and promote Environmental Power Washing are reaping the rewards of
their efforts. Environmental Power Washing is the growth area for Power
Washing Today. Just one example is the Post Office. In Fall of 1994 they
abruptly stopped all washing on their property that was not Environmentally
Correct. More and more customers will take this position as they become
aware that there is a viable solution to their cleaning problems. Another
example is the American Trucking Association which will hold their first
national conference on vehicle washing in April of 1995 in Fort Lauderdale,
Florida. Opportunity speaks, are you going to listen. Now is the only
opportunity you will ever have to make such a big impact on the
implementation of Environmental Washing Procedures with so little effort.
Timing is everything and the time is now!!!!
1997 Mobile Pressure Power Washing Environmental Update
By:
Robert M. Hinderliter
RAHSCO Cleaning Systems
October 10, 1997
Environmental Power Washing is not just Mobile Recycle Pressure Washing on a
Portable Vinyl Wash Pit. These are but two elements of Environmental Power
Washing just like "a", "b", "c" are letters of the alphabet. Simply stated
Environmental Power Washing is Pressure Washing with "No Off Property
Discharge" and discharging your wash water to the Sanitary Sewer. This
definition will fit most pressure washing operations that are being done
within Environmental Guidelines. It should be noted that "No off property
discharge" means above and below ground and discharge to Sanitary Sewer
means any place that is properly approved to receive your wash water. The
most common discharge location is Municipal Sanitary Sewer Systems (or POTW:
Public Owned Treatment Works). The preferred entry point is a Sand Trap, or
a Grease Trap. Many municipalities are also allowing other points of entry
such as slop sinks, mop sinks, sanitary sewer clean outs, commodes, inside
floor drains, etc.
For
Power Wash Contractors of the 21st Century water management will be as
important as the pressure washing. You will now have to have a tool box full
of tools for proper water management. Just as a carpenter has more than a
hammer in his tool box it will be necessary for the Pressure Contractor to
have more than one type of device to capture, control, and clean wash water
with. Because washing with a Recycling Systems on a Portable Vinyl Wash Pad
is the most expensive way to wash an item this needs to be the option of
last resort.
Recycle Systems do not remove the Total Dissolved Solids, Heavy Metals,
Detergents, Herbicides, Insecticides, or Pesticides. Hence the longer you
wash with Recycled Water the harder it is to get something clean and you
have to rinse with fresh water. Therefore washing with Recycled Water needs
to be the option of last resort. The same is true for washing on a portable
vinyl wash pit. Articles have to be moved to the wash pit. Often times
washing items in place then capturing the wash water is a less expensive
option.
Many
municipalities will now accept wash water with minimal pretreatment. This is
because the impact of the wash water from Contract Cleaners on the on the
POTW (Sewer Treatment Plant) is insignificant. It should be noted that each
municipality has the authority to determine what is acceptable within its
city limits. The problem is if you are in a Metroplex area where there are
many municipalities each one will probably have a difference set of
Environmental Pressure Washing Guidelines. What causes this is mostly
politics and jealousies among the cities.
Common
water control devices are (Tools for your tool box): Recycling Systems;
Pretreatment or sewer discharge Systems; Limited Recycling Systems; Wash
Pits (portable vinyl wash pads), Vacuum Sludge Filtering Systems; Wet-Dry
Vacuums, Sump Pumps; Drain Covers; Portable Dams; Vacu-booms; Oil Absorbent
Pads, booms, pillows, and tubes; plastic sheeting; Filter Tubs; buckets;
pans; and squeegees. You will be designing all sorts of devices to control
the water flow. Sometime that will just be using the terrain and natural
drainage and catching the water at a low spot to accomplish "no off property
discharge". Sometimes this can be as simple as using a wet/dry vacuum and
vacuuming up the water before off property discharge. Do not forget about
evaporation. A lot of contractors have used evaporation effectively enough
that they can wash for several hours and only have to recover less than 55
gallons of wash water. This has been done mostly by letting wash water make
long runs across concrete then capturing the water just before it leaves the
property. After the washing is finished they clean up the concrete. "No off
property discharge" has been achieved and the wash water has been discharged
to sanitary sewer. Environmental guidelines have been met.
Note
that in most locations if the wash water does not exit the property it does
not enter the jurisdiction of the Regulating Authorities.
