THE GREASE SUMMIT

Dear Attendee: I Congratulations! By your attendance at this summit, you have taken the steps necessary to increase your knowledge of grease and how it effects your community.

Grease is a common problem for many municipalities and communities. The objective of this course is to generate interaction among attendees and share information on systems, procedures, techniques, designs, etc. that work in controlling or reducing grease. We have also included information on systems and designs that appear not to work, and why.

We encourage each of you to have an open mind and contribute to the general discussions. It is your participation and input that makes this course a success! Your experience is valuable to the other summit attendees, so please share freely. This work book is a guide to be used in conjunction with the summit sessions. There is ample room for notes you will want to take during the session.

If you have any further questions regarding Environmental Biotech Inc." or its (GES) Grease Eradication SystemTM, please do not hesitate to ask. With experience nationwide and in many foreign countries, we are willing to share our knowledge with you.

hydro= water phobia= fear Hydrophobic = Water-Fearing

Lipid compounds. including greases, oils, and fats, are water-fearing, meaning they separate from water. Think of the old cliche of enemies "mixing like oil and water."

Y

Fig. 2

COAGULATES Because of its hydrophobic nature, grease clings to surfaces that are free of water. It also tends to cling to other grease already present - coagulation. With a specific gravity of 1, water is the benchmark for measuring the density of a substance. Grease has a

. specific gravity of less than 1, which means it floats when separated.

FORMS CLOGS STARTING AT THE TOP OF PIPES

The hydrophobic, coagulation, and specific gravity properties of grease mean it floats on water and clings to the tops of pipes. Sugars, starches, and heavier debris may collect on the bottom as the flow moves through the drain lines (fig. 1). Layer upon layer of grease builds from the top down (fig. 2) until water flow is blocked and a clog is formed (fig. 3).

ODOROUS Grease just smells bad. Obnoxious odors from rancid waste grease build-up emanate from drain lines, sinks, grease traps, lift stations, and floor drains.

THE GREASE SUMMIT


The Make-up of Grease LIPIDS

Grease, fat, and oil are all lipid-based compounds, derived from living cells of animal and vegetable matter. LIPIDS:

Any of various substances, including fats, grease, and waxes, t ha t with proteins and carbohydrates constitutes the structural principles A GREASE MOLECULE of living cells. A typical grease molecule (fig. 1) consists of three fatty

acids attached to a glycerol "backbone." _..

Fig. 1

TRIG LYCE Rl D E: The technical name for a grease molecule.

TRIGLYCERIDE A triglyceride molecule is made up of three carbon atoms joined to three straight chain fatty acids by an ester configuration.

Almost 95% of the weight of most seed oils is composed of various triglycerides. Free fatty acids compose the remaining 5%.

Highly stable: Chemically, triglycerides are highly stable molecules. They are extremely hard to break down, which makes treatment and disposal of waste grease very difficult.

MONOGLYCERIDES AND DIGLYCERIDES While most lipids are triglycerides, a small percentage have a different molecular structure. Monoglycerides have only one fatty acid attached to the glycerol backbone; diglycerides have two.

Grease 5eparation Technology

$0 The stable composition of the grease molecule must be considered when attempting to separate solids, grease, and oil. Effective grease separation technology takes into account four essential elements:

TEMPERATURE High temperatures emulsify grease. As the influent is cooled, grease and oil separate out and rise to the top.

@.-

' If the influent temperature is too high, emulsified grease will flow right through the separation device.

i

Generally, an influent temperature of below $5" F (29 O C) is sufficient for most lipid-based by-products in the food sewices industry.

TIME Emulsified grease needs sufficient time to cool and separate. The retention time needed to effectively separate out grease and oil will depend on the influent flow rate, amount of surfactants or chemicals, volume, and the size of the separation vessel.

Grease 5eparation fechnology

PH (between 5 - 9)

A low pH level, indicating acidity, has a tendency to "melt" grease, preventing it from separating and moving the problem down into the drainage system. A high pH level, indicating akalinity, will "cut" grease and emulsify it (chemical degreasers are commonly high pH). The emulsified grease moves down line where it coagulates as the alkalinity is reduced via dilution.

QUIESCENCE. Any turbulence, whether ongoing or periodic, which accompanies flows too great for the device's volume, will either prevent the breaking-up of grease and oil emulsions or tend to re-emulsify already separated materials. Additionally, turbulence keeps any solids stirred into suspension.

Volume is the most important feature to successfully trap grease.The device must be large enough, relative to the influent volume, to allow sufficient retention and cooling time. -

RESIDENTIAL

Obviously, restaurants use large amounts of grease in their cooking. While grease and oil from fryers, etc;; is collected and recycled, large quantities of grease are washed down the drains -- from washing greasy cookware to hosing down the floors.

Condominiums and apartment buildings often have grease- related waste problems. With a number of residents using only one drainage system, grease from cooking and dishwashing rapidly builds up in pipes and causes problems in the plumbing and sewer system.

Cleaning grease traps gets tongher under new laws By JAAN VanVALKEN’BURGH Times-News Business Writer

A new grease disposal law that went into effect across the state two weeks ago is still largely unknown to grease disposers.

As ofAug. 15, grease trap waste must be treated by a commercial treatment facility before disposal or recycling. The state regulation parallels federal law that went into effect Jan. 1. The mission behind the legislation is to protect groundwater.

The new regulations inadvertently ban several local septic disposal services from the grease disposal business - septic operators who previously dumped the grease in a designated Blountville field.

“The haulers are the ones who this rule mostly impacts. They should have gotten something in the mail,“ said Jim Haynes, administrator for Air and Water Progress for the state. Grease disposers who claim ignorance of the law should have paid attention during the two years this legislation was discussed, he said.

Local municipalities may regulate grease haulers and producers, said John Parks, an environmental. specialist with the state Division of Groundwater Protec- tion. Several state govemment divisions will also regulate restaurateurs who ille- gally dump their grease. For now, however, communication

remains the problem. Some septic and grease recycling busi-

nesses heard of the law last month from a state govemment mailing. Others in the grease business heard through the grape- vine.

“The Health Department didn’t even tell me to stop dumping,” said B.G. Flynn, owner of Big Boy Septic Tank Service in Kingsport. “I don’t want to break any laws, but I wish they’d tell me what to do with it.”

FIynn learned of the law from a fellow salesman, who learned from a business contact. Flynn isn’t too concerned, though.

“It’s not gonna hurt me, ‘cause I’m 6 1 years old anyway,” he said. And he does- n’t do a lot of grease trap business.

Stricter grease disposal regulation, however, may be inevitable, according to Ed Jennings, general manager of CBP Resources, a grease recycler in Knoxville.

The company was founded in Green ville, S.C., on the belief that “somewhere down the road recycling would be the only approved method of disposal,” Jen- nings said.

The new regulation could prove a boon to business, which is already Significant for CBP in the Tri-Cities.

“That‘s one of our best areas,” said Mike Howard, CBP transportation manager in the Knoxville office. He estimated he has more than 200 customers in the Tri-Cities.

CBP purifies the grease it collects, and recycles it into a protein supplement it sells to animal feed producers in the Southeast U.S. Most of the grease is used in poultry feed, Jennings said.

CBP charges about $75 to empty a 1,000 gallon grease trap, which is comparable, if not cheaper, than fees that were charged by local septic tank services before the law went into effect. Traps are of ten emptied every three or four months.

Cost may not be the problem for grease producing businesses. It may just be lack of knowledge or the inconvenience of finding a legal means of disposal. That means illegal dumping could be a problem if information doesn’t get out soon.

“That’s something I’d be looking for,” Jennings said.

Grease must be incinerated, recycled or specially treated for disposal in a landfill, state environmental specialist Lany Mat- thews said.

Firm Ordered to Quit Dumping State District Court Judge Robert Scott

for a temporary restraining order Friday. Another hearing will be scheduled within 10 days.

The company allegedly dumped sewage in manholes around the city after its permit to dump at the city's wastewater treatment plant was revoked in February. The city contends that the dumping violated city and federal health and safety laws.

However, Gregory Jarvies, president of the company, testified that stopping him would only eliminate about 10 percent of illegal dumping city-wide. He added that the restraining order would damage his reputation and his 15 year old company.

In February, an administrative hearing officer revoked the company's permits for failure to pay more than $33,000 in user fees.

Jarvies testified that he withheld payment because the city didn't uphold an agreement with him to prohibit grease dumping at the wastewater plant.

Jarvies invested in grease-holding and recycling equipment, but said he couldn't get restaurants and competitors to use it because recycling costs $200 a load, while dumping at the plant costs $20.

The BOD level in a facility's effluent is often monitored by government and health authorities to prevent pallution and keep POTW operating costs low.

High BOD levels result from high levels of waste in the effluent water. Grease and oil, as organic substances, are large contributors to high effluent BOD levels in facilities that produce greasy waste.

High BOD levels mean that bacteria are using much of the oxygen in the water in order to digest the waste. This lack of oxygen can kill fish and other aquatic life. High BOD is costly as well as environmentally damaging. If a facility's effluent BOD levels are deemed unsatisfactory by authorities, the facility may be slapped with hefty fines and surcharges. High BOD levels raise operating costs at the POTW that must deal with it.

Traditional Methods to Control Grease

Several different methods have been developed and used to meet the challenge of controlling the discharge of waste grease and the problems related to it. -

Soap, detergents, and degreasers surround the grease molecule, allowing it to "slip" through the drain lines. However, inevitable cooling and dilution return the grease molecule to its original form. Grease is simply relocated, causing problems further down the line in drain lines, grease traps, sewer lines, lift stations,

Enzyme treatments temporarily cut glycerol from fatty acids in the grease molecule. This allows the waste grease to slip through the drain lines near to the source. In some cases, glycerol will flash off, leaving only the fatty acids. These free-floating fatty acids have similar characteristics to triglycerides, except they are usually a little more frothy in nature. In other cases, the glycerol will re-attach to the free-floating fatty acids. The molecule may soon re-form and the grease and its related problems have just been relocated to other parts of the drain lines, the grease trap, sewer lines, lift stations, or the POTW. Products containing "free enzymes" cannot degrade grease and.oi1; they simply accelerate the problem down line.

WHAT DOES TRAP DO?

A GREASE A grease trap is designed to prevent grease, oil, solids, and other debris from entering the waste stream, where it becomes a problem by clogging sewers and disrupting the water flow in the system. A grease trap captures those wastes and contains them until they can be properly disposed of.

1s THE GREASE Most grease traps are located outside, often in the parking lots of the facility. Most can be recognized by the manhole lids that cover the accesses to the grease trap. TRAP LOCATED?

WHAT DOES REGULAR MAINTENANCE

A grease trap should be checked periodically to make stire it is working correctly. Backups, foul odors, high BOD, COD, or G&O levels. and other drainage problems may indicate

Grease interceptors are typically located next to the source of kitchen wastewater, such as a triple sink or a dishwasher. The capacity of most interceptors is under twenty gallons.

Restaurants using grease interceptors often suffer from frequently clogged drain lines, back-ups (and the related health hazards), and problems with meeting acceptable effluent discharge standards. Obviously, the interceptor is not working!

Grease interceptors BREAK all three parts of the Three-T Rule of Grease 5eparation. WHY? TIME

TEMPERATURE

TURBULENCE

If a triple sink (typically 40-50 gallon capacity) full of used dishwater -- loaded with emulsified grease -- is emptied, those 40 to 50 gallons of water must flow through a 5 to 20 gallon grease interceptor. With this kind of displace- ment ratio, there can be little or no retention time.

The water used to clean dishes by hand is almost always very warm-- and there is very little time between the sink and the interceptor for that water to cool and the emulsified grease to separate. Dishwashing machines use water that is close to boiling temperature!

The sheer volume of water and the force of the flow through the drain when a triple sink is emptied guarantee that the water is turbulent, keeping grease from separating and keeping solids suspended.

The result: The emulsified grease moves right through the interceptor and further down t h e drain system, where i t creates problems in drain lines,

grease traps, sewer lines, lie stations, drainfields, and P o ~ s .

THE GREASE SUMMIT

Mechanical Grease Separators

. Mechanical grease separators don't work for t h e same reason interceptors don't work -- they break the Three-T Rule.

Mechanical grease separators are very similar to grease interceptors in size and placement. In addition, they have a mechanical "oil skimming" device designed to remove "free-floating" grease and oil. The similarities between interceptors and mechanical separators mean that they are similarly ineffective in separating grease:

-No retention time -Water too hot -High turbulence

Although somewhat effective on "free-floating" grease and oil, the mechanical device cannot remove emulsified grease. it slips through the separator and into the drain and sewer lines and the grease problems begin.

Mechanical grease separators are usually demonstrated under controlled conditions. The separator is filled with cool water and oil is poured into it. When the unit is turned on, it skims almost all the oil from the water. However, once installed the unit rarely, if ever, operates under those conditions again: in a real, working kitchen, the water is hot, the retention time is almost nonexistent, turbulence is high, and the grease and oil is emulsified by surfactants. The separator simply can't separate the grease effectively .

The use of conventional septic tanks as interceptor tanks has proven to be very effective ... The larger volume provided by the septic tank has been beneficial in achieving the maximum possible separation of greases and oils."

a restaurant:

0 number of dining seats

type of restaurant (fast food, bar, etc.)

type of food served

0 anticipated daily water consumption

". ..> I

0 comparison with similar type of restaurant

already operating

location of dishwasher

location of water softener system

surcharges or fines

0 potential grease trap disposal problems

The most important part of a grease trap is the

sanitary T on the effluent side. It should

extend down to within 24" of the bottom of the

grease trap. It is recommended that a baffle

be installed in the center of the grease trap to

retain grease/oil on the influent side. There

should also be 2 access manhole lids. One lid

over the influent and effluent sides of the

grease trap. Also, a sampling or clean out port

should be placed before and after the grease

trap on the drain line.

TRAP ACCESS

The following factors should be considered when determining the correct size trap for a restaurant:

1. Number of dining seats 2. Type of restaurant (fast food, bar, etc.) 3. Type of food served 4. Anticipated daily water consumption 5. Size of traps in comparable restaurants 6. Location of dishwasher 7. Location of water softener system 8. Surcharges or fines 9. Potential grease trap disposal problems

.,, WHY: Without sufficient capacity, the three "T" Rule (time, temperature, and [controlled] turbulence) cannot be achieved. CRITERIA: Consider all the variables associated with each grease-producing facility when detennining proper grease trap sizing ratio.

WHY. To prevent water channeling. CRITERIA: It should extend far enough below the water level to prevent so that no splashing or excessive turbidity occur. This "T" should be four inches in diameter and vented.

WHY One of he most important parts of a grease trap design is the inclusion of a sanitary T on the effluent side. The purpose of this "T" is to draw a cleaner effluent from below the grease cap. CRITERIA: It should extend 112 of the distance fiom the water line to the bottom of the trap. This should also be four inches in diameter and vented.

WHY: To retain most of the grease and oil on the influent side and to reduce turbulence. CRITERIA: It is recommended that a baffle that extends well above and below the water level be installed two-thirds (2/3) of the distance toward the effluent side of the grease trap.

WHY: For visual inspection, thorough pumping and sanitary "T" cleaning CRITERIA: There should be 2 access manhole lids: one over the influent side and one over the efluent side. Additionally, two sampling or "clean out" ports should be installed on the drain line, one before the trap and one after.

'I 5ection 11: Recycling Pump Trucks

Pimp Trucks Recycling pump trucks are great for collecting contained, recyclable grease and oil, such as that from fryers.

When it comes to grease trap grease, however, they are less efficient. These trucks are supposed collect the water from the trap, separate out the grease. and then refill the trap with the "clean" grease trap water.

.e

Recycling trucks often collect only the surface layer (grease cap) of the grease trap, leaving behind solids that collect at the bottom of the trap. This organic matter leads to high BOD, COD, and TSS levels in the restaurant's effluent.

In fact, independent sources have found that grease and oil levels in the effluent may actually increase by using these trucks. The turbulence created by the pumping action emulsifies the grease and oil in the water, preventing it from separating and sending it right back into the trap it came from!

In many areas of the country, recycling pump trucks are prohibited from pumping or skimming grease traps.

With grease waste disposal costs skyrocketing throughout the United States, the advent of new technologies brings new hope and sometimes disappointment to those who service members of the food service industry, ONE SUCH DISAPPOINTMENT IS THE NEW DE-WATERING PUMP TRUCKS WHICH ARE MAKING THEIR WAY INTO THE GREASE-HAULING INDUSTRY. The new trucks are designed to filter grease, oil, and solids from grease trap waste water at the restaurant when a trap is pumped out, A problem has arisen which was not anticipated by either the manufacturer or the purchasers of these new de-watering trucks, Most Northern California cities and counties do not allow grease waste de-watering, In an impromptu telephone survey of Northern California Waste Water Treatment Plants, 90 percent responded unfavorably when asked about the new process,

Mr. Tom Davie EBI Seminar Lcadcr Environmental Biotech Incorporated 1301 Biotech Way Sarawta, Florida 34243

Dear Mr. Davic:

This lcltcr i s in rcsponse to your letter of August 13, 1999, regarding the Unitcd States Food and Drug Administration's (FDA) position on collcctiiig grcasc trrp waste and prwcssing i t lor iisc in animal fecd.

FDA is opimscd to tlic use o f any product that lips conie in contact with or passed through tlic samc drain as sanitary scwcr water or solid rnattcr us a coinponcnt of liuiiian or aiiiinal food. Furthcrtnorc. wc arc oppclscd to the use of grcase of unknown origin as a component o f human or animal food. Wc aflirmcd this position through rcgulatory action in August 1990 in wliicli a Warning I .cttcr was issucd to a Colorado firm and again in 1994 with Warning lctters to firms in Georgia and Alabama. Thc hasis for issuance o f the Warning Letters was that scwcr gIcnsc or grcasc of unknown origin i s ''unfit for fmd" aiid t h e f o r e adultcratcd because tlic potential containinants could not be known with any ccrtainty. Wc continuc to siipport this position. l h i s position spccifically addresses sewer grcase and greasc of unknown origin and should not be interpreted as uiiilaterally applying to all grcase trap wastc.

It is the position of FDA that a product intcndcd for usc as a rccd or feed ingredicnt must not hc itdultcratcd as defined in Section 402 (a) o f the Fcdcral Food. Drug, and Cosmctic Act (thc Act). Section 402 (a) of thc Act lias nuiiicrous provisions for establisliitig adulteration. 'I'hc tiiost appropriate suhscctions of 402 to apply to recyclcd grease trap greasc arc (a) ( I ) and (a) (3). Section 402 (a) ( I ) states in part Illat a fowl (fccd) shall bc dccnicd to be adultcratcd "if it hears or contains any poisoiious or dclctcrioiis suhstaiicc which may rcndcr i t injurious to Iicalth" and subsection (a) (3) statcs in part "if i t is otherwisc unfit lor food (fccd)."

FDA would oppose the use of grease trap waste froin floor drains, pot wash drains, dishwasher drains, sink drains. ctc. in aninial lccd &the contaminants were kriowii (or not prcscnt) and did not rcsult in unsafe tissue residucs in milk, mcat, and eggs or prcscnt a hcalth hazard to animals. Wc havc not opposcd the use in animal fccd of'restaarant grcasc' or 'slirdp' wlicn it consists critircly o f cdiblc byproducts uscd in, or obtained from, the preparation of Iiuman food.

Our principle concerns over the usc or grcasc trap waste are related to the poorly defined naturc o f thc product; tlic nunicrous sources that can rangc from restaurants, to laundries, to industrial manufacturers; tlic collcctioii veliicledreceptacles which can vary from dcdicated trucks and reccptacles to collcctioii by tlic sanic trucks uscd to pump septic systems; tlic variety of contaminants possible; and the level of control (or lack of control) eiiconipassed by local, and State lawdregulations.

In addition to the concerns stated ahove, the proccssing of grease trap waste, or other potential recyclable material. can vary from minimal with no testing for contaminants to commcrcial proccssing, such as rcndcriiig. with pcsticidc arid clicrriicnl scrcctts. Clearly. with all these variahlcs. rcyulaling tliis portion ol'tlic rccycliiig iiidustry is clinllcnging. Rcgulntiiig it ollicr tlian on a case-by-cnsc basis at tlic I:edcral levcl is curretitly not Feasible.

Case-by-case cvaiuations are currently made by FDA regnrding the safety of these products and their compliaiicc with die Act. The evaluations do not address whether tlic collection. disposal and processing oltlicsc protlucts coiiil)/y with Statc. local, or other Fcdcral laws, which might apply to wastc disposal.

I

Mr. Davie

Tile safety evaluations are currently made using all available information. This infomation includcs, but is not limitcd to, thc source (i.c. restaurants, food processors, ctc.); the contaminants present or likely to be present; the proccss used in processing the material for animal feed; screening procedures for detecting chemical, microbiological, and filth contaminants; collection methodshehicles; and agreements between tile supplier and processor outlining the suppliers responsibilities for preventing contamination of the recyclable material.

With regard to screening procedures, a heating step of at least 1 80 degrees Fahrenheit for 20 mmutes would be adequate to address our microbiological concerns and a method for detecting and removing metal, glass, etc. would largely address filth. Pesticide screens should, at a mmimum, be able to detect halogenated (lindane, heptachlor, dieldrin, aldrin, etc.) and organophosphate (malathion, etc.) pesticides. Chemical screens should detect halogenated compounds, particularly polychlorinated biphenyls (PCBs). The particular pesticide and chemicaI screens \vi11 need to be tailored to the business. A commercial laboratory should be able to provide this advice.

In addition to FDA guidance, the 1999 Official Publication of the Association of American Feed Control Officials (AAFCO) includes a Note in the Fats and Oils section and definitions addressing this issue (copy enclosed).

In summary, it is possible to envision scenarios for the handling and processing of grease trap waste that could result in a final product acceptable for animal feed and others that would not result in an acceptable ked product.

It is our hope, that with the information provided in this letter, that both the processor and generator will be able to structure their operations so that the resulting product is not adulterated and complies with both Federal and State regulations. If we can be of M h e r assistance, please contact me at Division of Anima! Feeds, HFV-220; 7500 Standish Place; Rockvi!le, Maryland 20855; or by telephone at

Sincerely, (301) 827-6657.

NOTE The use of the term "feed grade" requires that the specific type of product be adcquatcly tested to prove its safety for feeding purposes. In mixed feeds containing fats or fat derivativcs the term "feed grade" may be omitted in the ingredient declaration.

NOTE Any mixture of two or more fats or fat derivatives defimd below is to be identified by listing each component: Le., "animal fat and hydrolyzed vegetable oil." .

NOTE: Fats or fat derivatives must come from acceptable animal feed sources. Waste water sludge that contains sanitary sewer water, is not an acceptable source of animal feed. FDA should be contacted regarding the safe use in animal feed of all other sludge material that does not contain sanitary waste water.

Grease T i p Dkposal

Proper Pumping Procedure A designated representative should observe and monitor all grease trap pump-outs to ensure proper pumping procedure is followed. Unless it is absolutely unavoidable, you should use a trustworthy pumper with whom you have a relationship.

A quality pumper will follow the “5-Side Rule.” According to this rule, all four walls and the bottom of the grease trap should be cleaned thoroughly. Make sure your pumper observes this rule and the following proper pumping procedure:

Step 1 : Skim the entire grease cap and debris from the top of the water in the trap. You may need to agitate the trap prior to pumping to loosen the grease cap.

Step 2: Place vacuum tube all the way into the trap to suck remaining solids from the bottom.

Step 3: Vacuum water out of the trap.

Step 4: Clean the sides and bottom of the trap. This may be done by “back flowing” the water from the pump truck and jetting any remaining scum from the trap (check local regulations), or by using a hot water source (usually located in the back of the restaurant) to hose down the trap. Make sure the trap is completely clean.

Step 5: Vacuum remaining water out of the trap.

Step 6: Check that the sanitary “T’s’’ on the inlet and outlet sides of the trap are not clogged or loose.

Step 7: Make sure that the baffle is secure and in place.

Step 8: Inspect the trap for any cracks or defects.

Step 9: Check that lids are securely and properly seated after completion of pumping.

THE GREASE SUMMIT

Grease Trap Disposal Monitoring

Implementing a system to monitor the collection transportation, and disposal of grease trap waste -- or any industrial waste-- is highly recommended. Such a system reduces the incidence of illegal dumping, high municipal costs, and potential for environmental damage.

A designated disposal site should be chosen for all grease trap and septic waste. A separate facility should handle the disposal of industrial waste.

Every pump truck registered in your county should be tagged. A device similar to an electric meter box is attached to the discharge valving on the pump truck. This device can only be removed by an operator at the designated disposal site. After the truck is emptied, a new tag should be attached at the disposal site. (See Sarasota County Ordinances 90-61 and 93-86 on the following pages.)

USING A TAGGING SYSTEM

KEEP RECORDS Accurate records safeguard the grease disposal monitoring system. The pumper should keep a record of where the pump truck's contents came

that may be checked in the during an inspection. from. The restaurants keep corresponding receipts i )

BE IT ORDAINED BY THE BOARD OF COUNTY COMMISSIONERS OF SARASOTA COUNTY, FLORIDA:

Section 1. Findings. The Board of County Commissioners of Sarasota County, Florida, hereby finds:

(I) The pumping out, cleaning, or otherwise servicing of septic tanks, holding tanks for temporary privies, grease interceptors and package wastewater treatment plants can produce health and safety hazards and environmental pollution if not conducted by qualified operators in accordance with certain standards and procedures.

'3

(2) Disposal of liquid wastes collected from the sources described above, at any place other than an authorized disposal facility, is harmful to the public health and the environment.

(3) Evidence suggests from past occurrences that regulations requiring proper disposal of liquid wastes, which are based on voluntary compliance, are not adequate and effective to protect against improper disposal of such liquid wastes.

Friday, June 18,1999

Dan Miller City of Gillette Gillette, WY

Dear Dan:

I have received the copy of the City of Gillette draft of the local ordinance amendment. Environmenta Biotech shares in the concern for management and monitoring of grease and oil waste into the central sewer system and treatment plant and encourages the use of governing agencies powers to better manage these situations. The proposed ordinance contains many of the key elements we determine are essential to reach these goals. There are a few areas in the proposal we discussed that may need additional consideration.

The following is a list of these areas we discussed:

Retention caDacity - 4" to 6" grease/oil cap, 12" to 16" solids Recvclable oil - necessity of an on site holding tank and agreement to have serviced on a regular basis Garbaqe disposals - reference to connection, use and maintenance Freauencv of pump outs - generally a requirement to pump out every 3 month, 2 month or monthly, with the availability of a variance, is most common. A time frame of 6 months between pump outs is far to infrequent based upon our experience unless a service treating and monitoring trap conditions is in place. Enzvmes - Many communities are now disallowing the use of enzymes due to the ability of these products to emulsify grease and oil, thus passing through to the central sewer system

/

I believe the City of Gillette has designed a well thought out program in this matter. The above items are offered as suggestions based upon in field observations, experience with other communities, and general information provided by the Environmental Biotech network of Strategic-Partners. I hope this assists in your final determinations for the amendment to the City of Gillette municipal code. I am available at the above number for any additional assistance.

Since re1 y,

PROCEDURE TO DETERMINE ALTERNATE PUMPING FREQUENCY I

All businesses are required to pump out the contents of the grease interceptor at least once every 30 operational days, or as necessary to prevent accumulation of more than 6 inches of grease on the surface of the interceptor or of more than 8 inches of solids on the bottom of the interceptor. The Liquid Waste Hauler mustmeasure the dapth of the grease cap on the surface of the grease trap and the depth of solids on the bottom of the grease trap adjacent to the outlet pipe prior lo pumping the trap to ensure that excesslve accumulation has not occurred since the last pumpout. If the above performance criteria can be met using a less frequent pumping interval, the County may authorize an altemate frequency as provided below. The maximum pumping frequency that shall. be approved is once every 180 operational days.

To Determine an Altemate Pumping Frequency:

1. Check the level of grease and solids in the grease trap aft er 30 days, If them are less than 4 inches of surface grease and less than 6 inches of bottom solids, you are not requlred to pump out the grease trap. Document thfs lnformatlon. If them. are more than 6 inches of surface grease or more than 8 inches of bottom sollds, you must increase the pumpout frequency as necessary to comply with these standards.

2. Check the level of grease and sofids in the grease trap every 10 days after the first ins ction, until the level of grease reaches 6 inches or the level of solids reaches 8 inc R es. Document these checks. Pump out the grease trap at thii time. fhb will set the proposed pumping frequency. This frequency may not exceed 180 days.

3. At the interval established in step 2, rei-inspect the trap. If the level of grease is at or . below 6 Jnches and the level of solids isat or below 8 inches, then you may raquest this interval as the approved pumping frequency by signing the Certification below. If the grease or solids have exceeded the allowable depth, then Steps 1 through 3 shall be repeated. If the proposed pumping interval is more than 00 days, the trap must be inspected after 90 days.

4. I am requesting an alternate grease trap pumping frequency based on other factors, as described here:

Certification:

I am requesting an altemate grease tra pumping frequency of on- every days

THE GREASE SUMMIT

Xecommendatlons for Ordlnances INFORMATION FOR SYSTEM DISCHARGERS

The Australian Water Board's Guidelines for the Onsite Treatment of Trade Wastewater Dischargers is a good example of a format to use and what type of information to provide to discharge users (consult section 12.7, Grease Summit Manual). Additionally, the Australian Water Board also publishes a guide, Trade Waste Branch: Management Guidelines for Trade Waste Dischargers (consult section 14, Grease Summit) that lists approved:

* Wastewater consultants * Analytical laboratories * Equipment suppliers * Miscellaneous service providers

This is of great benefit to the discharge users and helps to provide necessary information and assistance.

GREASE TRAP SUING

For sizing ratios refer to section 9 (Grease Trap Design Review). There are numerous ways to determine grease trap sizing and account specifics play a large role. Due to the multiple factors and variables, one ratio does not work in all circumstances. Experiment with different ratios and decide which one@) work in your area.

)

GREASE TRAP DESIGN

After determining the proper size, refer to section 10 (Recommended Grease Trap Design) for specific design criteria.

All grease trap designs proposals for new facilities or existing facilities must be submitted to the Department of Environmental Engineering for review. Final grease trap design approval will be granted by the Director of the Publicly Owned Treatment Works.

GREASE TRAP MAINTENANCE REPORTS

It will be the responsibility of the facility to contract with a locally licensed septic pumping contractor and maintain a record of each grease trap pump out. It is required that each grease trap be inspected and documented on an annual basis by both the licensed septic pumping contractor and a representative from the Department of Pretreatment Inspection Program. A grease trap pump out is required on an annual basis or as required by the Director of Pretreatment Inspection Program. All grease trap pump out records and annual grease trap inspection receipt will need to be displayed along with your Health Department Inspection Certificate. Failure to do so may result in a required grease trap pump out, or a fine issued by the Director of Pretreatment Inspection Program.

If upon inspection, the grease trap is found to have over 1 2” of solids in the bottom of the grease

compliance levels, based upon grease trap effluent sampling, the Deportment of Pretreatment Inspection Program representative can require a grease trap pump out. If required, the restaurant will need to have it’s grease trap pumped out, cleaned, and transported to a designated disposal site.

- trap (using a Sludge Judge) or a grease cap of over 3” or the restaurant exceeds discharge I

Removal or skimming of only the grease cap layer should be prohibited. AI1 Grease traps and interceptors should be pumped entirely clean and dry.

No de-watering or recycle trucks should be allowed for “brown grease” removal.

GREASE TRAP HAULING/DISPOSAL AND MONITORING

Sydney Water Board has an excellent program for total waste tracking. By using bar coded dockets and computer scanning, the chances for human falsification are greatly decreased. Refer to section 12 (Grease Trap Disposal Monitoring).

Sarasota County, FL and Cheyenne County, WY has a very good example of an ordinance that “tags” a septic tank pumping truck to ensure that no illegal dumping can be attempted (consult section 12, Grease Summit manual, Ordinance 9386).

Fulton County Department of Public Works has a decent tracking format to monitor, point origination of grease trap waste, transporter, and disposal location (consult section 12, Grease Summit manual, form 000099).

DISCHARGE PERMIT

All facilities that commercially prepare food for distribution to the general public, should be required to obtain a Users Discharge Permit from the Director of Publicly Owned Treatment Works ofice. Any pre-existing facilities that change ownership should be required to re-apply for a Users Discharge Permit at the Director of Publicly Owned Treatment Works ofice. See Pima County, A 2 for discharge limits.

GREASE PRETREATMENT

1 ) All newly constructed facilities will be required to install an approved, external grease trap with a minimum size of 750 gallons and not exceeding 3000 gallons in capacity. If required by Department of Environmental Engineering, for high volume facilities, grease traps can be arranged in series to provide additional retention and separation time. All grease trap designs will require review and approval by the Department of Environmental Engineering, with final approval given by the Director of the Public Owned Treatment Works.

15.21

THE GREASE SUMMIT

2) Existing facilities without an external grease trap are encouraged to install an external grease trap to meet POTW discharge compliance (see Pretreatment Program Monitoring). Should the facility choose not to install an external grease trap and exceeds discharge compliance levels, the facility may be subject to discharge fines based on eflluent parameters. The Director of Pretreatment Inspection Program's office will be responsible for facility emuent quality monitoring. Failure to submit payment for such discharge violations or required compliance measures set forth by the Director of Pretreatment Inspection Program, within the stipulated time frame, will result in termination of water supply to the facility by the Department of Water, resulting in facility closure by the Department of Health.

3) New facilities that are limited by space or other factors and cannot install a grease trap as specified, will be required to install and maintain internal grease interceptors a minimum of 20 gallons in size. Weekly maintenance by facility personnel will be required. Monthly maintenance inspection will be conducted by a POTW representative. The POTW can require a grease interceptor clean out during the time of inspection if necessary. Should the Cacility not meet discharge compliance levels, the facility may be subject to discharge fines based on emuent parameters, as stipulated above.

4) No mechanical grease recovery units should be allowed.

ALTERNATIVE TREATMENTS

The use of any free-enzyme, chemical, or other products designed to emulsify, liquefy or further render grease soluble for the purposes of clearing drain lines or circumventing the intended design of the grease trap, is prohibited. See City of Fort Worth, TX ordinance.

All potential vendors with products claiming biological activity, will need to submit product marketing literature, Malerial Safety Data Sheet, and a sample of the product to the POTW for review and approval. Product evaluation under actual field testing, may be required by the POTW. All expenses for POTW field testing will be reimbursed by the vendor or manufacturer of the biological product. Final product approval will be given in writing, by the POTW.

GARBAGE DISPOSALS The installation of a garbage disposal into any commercial food facility should be prohibited. Older plumbing codes required garbage disposals to be plumbed into black water lines. They must be piped to grease linedgrease traps if allowed at all.

T H E GREASE I

SUMMIT

PRETREATMENT PROGRAM MONITORING

It is the responsibility of each restaurant to maintain their effluent discharge quality. Failure to do so may result in monthly effluent sampling by the Department of Pretreatment Inspection Program. Surcharges or Fines will be accessed based on the following parameters:

Biochemical Oxygen Demand should be less than 300 mg/l

Chemical Oxygen Demand shoiild be no greater than 2.25 times that of BOD

Total Suspended Solids should be less than 200 mg/l

pH should be between 5 and 9

Grease and Oil levels should be less than 100 mg/l

Grease trap effluent water temperature in excess of 1 10 F.

Each violation should be based on the total water consumption by a facility. i

All surcharges should be added to the food facility's monthly water bill for payment.

RESTAURANT WASTEWATER RESPONSTRTLTTY

Each restaurant facility is responsible for their wastewater discharge quality and the proper disposal of their grease trap contents. Failure to comply with either effluent discharge levels or proper, legal disposal of grease trap contents, may result in possible fines.

WASTEWATER SURCHARGES

Orlando, FL has a good surcharge/pretreatment ordinance that has been very effective in reducing industrial strength wastewater discharges. Refer to Section 14 (Review of Various Ordinances).

SAMPLING PROCEDURES

All sampling should be done using the recommended method from the EPA Handbook for Sampling and Sample Preservation of Water and Wastewater. All samples should be taken at a combined effluent point, meaning a combination of black and grey water, using an approved sample port. Installation of this sample port should be the responsibility of the facility to be tested. .

PROCEDURE TO DETERMINE ALTERNATE PUMPING FREQUENCY

All businesses are required to pump out the contents of the gfuass intemptor at least o m every 30 operational days, or as necessary to prevent accumulation of mom than 6 inches of grease on the surface of the lnterceplot ot of mom then 8 inches of solids on the bottom of the interceptor. The Liquid Waste Hauler must.memum tho depth af the grease cap on the surface of the gkme trap and the depth of solids on the bottom of the grease trap adjacent to the outlet pipe pmt to pumping the tmp to ensure that - excessive accumulation has not occuned since the last pumpout. If the above performance criteria can be met using a less frequent umping interval, the County may authorize an altemate frequency as provided below. 4 e msudmum pumping frequency that shall. be approved is once every 180 operational days.

To Determine an Attenrate Pumping Frequency:

1. Check the level of grease and solids in the grease trap after 30 day$, If them are less than 4 Inches of surface grease and less than 8 inches of bottom solMs, you are not requlnd to pump out the grease trap.

The Na!icna! €nvirotlmenlal keaith Association had its origins In the state C I ~ California where it was incorporated in 1937. The original impcs!us behind the creation 0 1 a national PmfeSSlonal soclety far cnvironmental hea!!h practitioners was ths deslre by professionals of that day :o establish a standard of excellence f o r this developing profession. This standard, which has come lo be kno%n as (he Registered Environmental Health Speclalist or Registered Sanitarian credential. cvidences that one has mastered a body of knowledge (which is verilied through the passing of an examlnalicn) and has acquired sufficient experience, thereby Indicating that work responsibilities in the environmenfal health field can be satisfactorily performa. The pioneers of the association believed I h G I sach a credential was ncc6ssary If the environmeillal health field wag 10 grow and lake shape as a legitimate and widely rqX?ct€?d p o l e sslo n -

Drawing on the origlnal effort that lad to the creation of NEHA, the association today $rands as a 5.700 member strong professional society. NEHA offers a variety of programs Ohat are all in keeping with the association's mission which is as relevant today as it w6s when the organization was founded. The mrsslon of the National Environmenlal Health Association IS. "to advance Ihe envlronmenlal health and proiection profcsslonal for the purpose of pmviding a he a It h f u I a nv i r on m e n t to r a I I. "

In pursuit of its mission, NEHA sponsors a variety of programs. Today, the assodation offers four credentials, (the Registered Environmental Health Gpecialist, the Environmental Health technician, the Registered Hazardous Subsrances Professional, and t he Registtlred Hazardous Substances Specfallst.) Plans now are undcway to develop an advanced level management credential for the environmental heshh prolessional. In addillon, NEHA conducts an annual educatbnal conference and a number of technfcal workshops each year, publishes tho widely respected and peer reviewed Joumel at Environmenfal Health supports professional conlinulng education, lunctlons as a "one stop shop" for publications that give the NEWA member education In virtually every area of the environmental field, snd performs addltionel services ranging from networkin9 10 commillee participalion opportunities, to t h e development of positions on rimety and sedous environmclnlat concerns.

The pursuit of NEHA's mission is manifested rhrough the various programs that the association sponsors. J u s t as Important. however, is the manner In which it conducls these prog r B ms .

Advancement has Men detined by NEHA In lerms of both education and mlivallon. 'The basis for ihe association's activilies is the belief that t h e professional w h o is educated and motivated Is the professional who wll! make the greatest conlrlbution to the healthful envfronment goals which we all seek. Accordinply, great emphasis Is placed Or1 providing, lhrough each 01 N E W ' S programs, both an educational as well as a mOt!VatlOnal klck.

To undertake the various programs of the association, NEHA employs twelve paid professionals. NEHA's program areas include meetings and technical workshops, pubiications, credenlialing, the Joumaf of Envtmnmental Health , research and development and markeilng and sates. Serving at the pleasure of the assoclarion's board of dlrecIors IS a full time c h i d executive who functions in \he capaclly of the association's execulive diroclor.

The association Is governed by a fifleen-member board of directors that is chaired by the association's president. In all, NEHA has five national officers (second vice president, first vice presidenl, president-elect, president, and immedlate past president) who serve on the assoclatlon's executlve commlttee along wlth nine reglonal vlce presidents (RVP's) who each respectively represent various regions of the nation. (A regionat vice presldent, for example, wlll represent II block of s taks . ) A tenth RVP represents NEliA's national affiliates (The Industry Affiliate, The Uniformed Services, The National Associetlon of Noise Control Officials, and the Natlonal Conference of Local Environmental h'eallh Administralors).

Serving under the associatlan's board of directors is an array of various administrative and functional commiltees. In sddltlon, members can participate in the association through another array or commillees \hat are ocganlted within nine distlnct technlcal sections which, for NEHA's purposes, essenttally divide the environmental field. Those sections Include AirlLand/Waler, Environmenlal Health Management, Food Protecbn, General Environmental Heallh, Injury PrevenlionlOccupational Health, tnstitutlonai Environmental Health, Hazardous and Toxic Substances, On-site Wastewater Management and Internationel Environmental Health.

NEHAs large and growing membershlp encompasses the pub/& and the private sectOrS as well PS academla and the unlformed servtcss. The association's Journal has subscribers in Some fifty-three counlrlea from around the worJd.

White a majority of NEHAs members work in the public seclor, (many are employed by local county health departments In the role or generalists), we conslantly are moving toward a membershlp which is representative of the entire envlronmental heallh field. The only qualifcalion to be a regular active NEWA member is lhat Ihe lndlvldual be a professlonal who IS employed in the environmental field. This has given NEHA a most unique pasilion of being Ihe single organization which, because 0 1 its dlverdty, offers a forum for dlscusslon of \he Issues. In lhia way we y,!lJ find the solulions we alt seek4ogether.

It is \he associalion's desire to foster more cooperation and understanding between and among environmental health professionals, to conlrlbute to the resolution u! rhe worldwide eflVlfOnmental healih Issues, and to work with olher nallonal professlonal societies lo advance !he cause, the image, and lhe professional standing ot the envlronmental health professbn. At the same h e , NEHA remalns solidly founded by Its roots in sfforts to tmprove the environment In America's cltles, towns, and rural areas In otder to creale a more healthful envkmmenl and qualify of 1116 for us all.
