1. Do I need a Wastewater Discharge Permit?

All non-residential wastewater dischargers may be required to complete a permit application. The purpose of the permit application is to identify the volume and characteristics of the wastewater to be discharged into the sanitary sewer. The following procedure will be utilized to determine whether or not a user must submit an application:

These questions are to be answered and will help with the review. A "Yes" answer to any item with a * means the Industrial User is considered a Significant Industrial User (SIU) and will be permitted as such.

• Does the discharger have a manufacturing process that generates wastewater?
• What is/are the Standard Industrial Classification (SIC) code(s) for the facility?
• Are there chemicals of concern stored on site?
• *Is there treated groundwater or site remediation wastewater generated?
• *Is there more than 25,000 gallons per day of process wastewater generated?
• *Is the proposed discharge subject to categorical pretreatment standards under Title 40 of the Code of Federal Regulations?
• *Could the proposed discharge adversely affect the Publicly Owner Treatment Works (POTW)?

The Cedar City Regional Wastewater Treatment Facility, (CCRWTF) requires an industrial Wastewater Discharge Permit Application from a Significant Industrial User (SIU) at least 90 days before they discharge to the sanitary sewer.

The CCRWTF will issue industrial wastewater discharge permits to SIUs where pollutants of concern are, or have the potential to be discharged at levels that could: impact the POTW, impact the environment, or affect worker health and safety.

Industrial users who are considered categorical, but who discharge no process wastewater to the sanitary sewer system may be issued a Zero-Discharger Categorical Industrial User Permit (ZDCIU),
The CCRWTF may elect to issue discharge permits to non-Significant Industrial Users under a local control program.

Examples of such industries may include, but are not limited to:
• Food processors with less than 25,000 gallons per day process wastewater
• Metal fabricators or machine shops without surface finishing operations
• Concrete products manufacturers and ready-mix batch plants
• Electronic circuit board assembly, wave solder, solder reflow, board washing and testing
• Operations without either electro-less or electrolytic plating or chemical etching or milling
• Beverage processors including dairies, breweries and soft drink operations with less than 25,000 gallons per day process wastewater
• Testing laboratories, either analytical or product
• Chemical re-packagers, and container recycling activities
• Any discharger required after a review to implement effective control of the outgoing or effluent discharge concentrations representing components of the Local Limitations, and related priority pollutants, (Biochemical Oxygen Demand, (BOD) Total Suspended Solids, (TSS), Oil, and Grease, (O&G), pH, Metals, (As, Cd, Cr, Cu, Hg, Se, Pb, Ni, Ag, and Zn)).

The CCRWTF may also elect to issue permits to those industrial and commercial facilities without the need for monthly reporting or frequent oversight. These permits are classified as Best Management Practice (BMP) permits. BMP permits require less frequent inspection and oversight. Examples of such industries may include, but are not limited to:

• Vehicle and equipment washing and maintenance activities
• Electronic equipment testing (no manufacturing activities)
• Industrial gas repackaging and vessel hydro-testing
• Warehousing operations
• Transfer and recycling operations
• Small-scale food or beverage processors, who, after review, require no pH control of their wastewater discharge.

FOG (Fats, Oils & Grease) Commercial Program
Sanitary sewer overflows (SSO) and sewer line maintenance due to FOG (fats, oils and grease) waste have been on the rise. This has prompted stricter enforcement of Ordinances and Regulations governing FOG discharge into the sewer system. Enforcement requires the installment and proper maintenance of a pretreatment device commonly known as a GRD (grease removal device).

1. Grease Trap (indoor) - Intended for limited food or drink preparation, typically found very close to a pre-wash sink.

Defined As:
Grease Trap. Shall mean a device for separating and retaining waterborne fats, oil, and greases, it shall be installed under a sink as an accessory to an operating certified Grease Interceptor. The installation of grease traps on all new source commercial or industrial establishments, in lieu of the installation of a certified grease interceptor will be strictly prohibited under any circumstances.

2. Grease Interceptor (outdoor) - Intended for food and drink operations, found outside because of large capacity for FOG materials and its lower maintenance costs.

Defined As:
Grease Oil, and Sand Interceptor. “Grease Interceptor” shall mean a device for separating and retaining waterborne fats, oil, and greases before the wastewater, which contains such grease, exits the grease interceptor into the city’s wastewater collection system or POTW. The grease interceptor also collects settable solids generated by or incidental to commercial, industrial and food preparation activities. The Grease Interceptor shall at a minimum be equipped with a two-cell construction and be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. The interceptor shall be of substantial construction, water tight and equipped with easily removable covers which, when bolted in place, shall be gas and water tight.

All new FSE (Food Service Establishments) are required to have a minimum 500 gallon Grease Interceptor, (Outdoor-GMD) grease removal device.

2. Do I need a grease interceptor?

If you’re Food Service Establishment, (FSE) and/or facility are providing any type of food or drink service you are required to have a GRD connected to the kitchen’s sewer system. Other helpful hints: If you are licensed by the Health Department or Department of Agriculture or engage in providing a large number of meals you are required to have a Grease Removal Device (GRD).

For existing commercial kitchens without grease traps or interceptors, the General Manager may require the installation of a new grease, oil, and sand interceptor that fully complies with the definitions found within ordinance 30a, or to modify, replace, or repair any noncompliant plumbing or existing grease trap or interceptor upon notice to the food establishment, and (or) commercial kitchen facility that one (1) or more of the following conditions exist:

1. The facility is found to be contributing fats, oils or grease in quantities sufficient to cause sewer line stoppages or to necessitate increased maintenance on the wastewater collection system; or

2. Changes are made to the menu or kitchen equipment that, in the opinion of the General Manager, threatens to contribute fats, oils, or grease in quantities sufficient to cause line stoppages or necessitate increased maintenance on the wastewater collection system.

Grease interceptors shall be required of all new source commercial or industrial establishments upon construction where deemed necessary. Any existing food establishment will be reviewed to determine if existing mechanical, building, plumbing and electrical system will require upgrading. Any new kitchen, which shall meet the definition of a “food establishment”, shall meet all the mechanical, building, plumbing and electrical requirements for a commercial kitchen.

All existing commercial or industrial establishments shall have one year upon notification from the CCRWTF to install a grease interceptor where required.

3. What is a Grease Removal Device, (GRD)? How does it work?

A GRD is a piece of equipment connected to the sewer line close to the source of FOG (fats, oils and grease) being discharged. It is made up of a baffle system inside intended to slow the discharge long enough for the FOG to separate from the gray water (retention time). The FOG floats to the top of the reservoir inside the device, gray water flows through the sewer system and food particles drop to the bottom of the reservoir.

FOG Training is a Best Management Practice (BMP) for kitchen operations

A FSE (food service establishment) can request a technical assistance visit to learn how to stay in compliance. Please contact Peter Sury, Cedar City Pretreatment Coordinator (435-867-9426 X: 304) or email spete@cedarcity.org to arrange your first technical assistance inspection.

5. How should a Preferred Pumper, Waste Hauler or other rendering companies service my GRD?

VERY IMPORTANT: Management should observe and inspect service performed.

Existing Grease Traps:
• Vacuum out all FOG and food debris
• Scrape sides and lid (remove all 3D debris)
• Take out baffle and scrape clean
• Check and clean inspection port, opened and cleaned
• Pour water down side to flush waste to bottom for pump out
• FSE inspect for quality of work performed before it is filled with water and closed
• FES or Preferred Pumper note any damage or needed repairs on FOG report
• FSE or Preferred Pumper note FOG level and solid level on FOG report
• FSE or Preferred Pumper submit FOG report

Interceptor:
FSE should observe the first and last 10 minutes of the process at minimum.
• Either plunge vacuum wand up and down while taking out waste or leave wand at bottom and scrape all sides of vault in a plunging motion with a scraper wand.
• Pressure washes all FOG material to bottom of vaults (walls, fittings) and vacuum into truck.
• There should be no visible FOG material and inlet/outlet tees should be very clean.
• Note any damage or needed repairs.
• FSE needs to inspect quality of service when done.
• FSE or Preferred Pumper note any repairs needed on FOG report.
• FSE or Preferred Pumper note FOG level and solid level on FOG report.
• FSE or Preferred Pumper submits FOG report.

6. What if I don’t install a grease trap?

If your facility is in this category, and has been determined by the CCRWTF to need a GRD, you will have one year upon notification from the CCRWTF to install a grease interceptor where required. Upon exceeding this time frame, fines may be imposed for non-compliance. Current regulations state that a facility causing a sanitary sewer overflow (SSO) is in violation of the Clean Water Act and enforcement actions may have the facility pay for all costs involved.

Read the Rules and Regulations:

• Local Limitations
• Ordinance 30a
• Code of Federal Regulations (section 403.5 National pretreatment standards: Prohibited discharges)
• Plumbing Code

7. How can I be sure I am in compliance with the rules?

• Proper maintenance of this device is removing the accumulated FOG and solids on a 25% to 30% capacity rule. After the device has reached 25% capacity of both FOG and solids, FOG begins to pass through, so proper maintenance is essential to stay in compliance and save on equipment costs.
• FSEs must keep records of GRD pump outs for inspection.
• FSEs or Waste Haulers must submit to the CCRWTF, all required reports as necessary to provide proof of compliance.

8. What is the criterion for grease trap/interceptor inspections?

All FSE located within Cedar City Utah are on an inspection schedule. All kitchen facility operations are different; so one standard can't be used to determine GRD size and/or cleaning frequency. The grease trap/interceptor shall be inspected using the following criteria:

• If the trap/interceptor is in good condition, you will be advised to keep an eye on the maintenance schedule and kitchen operations.

• If a trap/interceptor is found in fair condition you may be issued a non-compliance order, and/or formal letter of Non-Compliance. To this point the CCRWTF may require an increase in related cleaning frequency and/or improve your BMP (best management practices) policy for kitchen operations.

• If the trap/interceptor is found in poor condition you will be issued a non-compliance order to have the grease removal device cleaned immediately and, immediate measures to prevent a future re-occurrence shall be enabled. The CCRWTF may require the removal on grand fathered under the sink trap, and require the installation of a minimum 500-gallon in ground grease interceptor. As well, the CCRWTF may impose penalties, and/or fines at this level of enforcement. The facility will also have 30 days to submit invoices of cleaning as proof of corrective action to the CCRWTF.

9. What about maintaining my GRD?

If you have a grease trap/interceptor, maintain it properly. Work out a specific cleaning schedule right for your restaurant. All GRD's need to have the separated FOG cleaned out periodically. Frequent cleaning can eliminate smells associated with a poorly maintained GRD. Chemicals and extremely hot water only push the problem further down the sewer. It does not go away. You can hire a Waste Hauler, or plumber to maintain your GRD and handle the required paper work for the control authority. Stop FOG at the source to prevent overflows and additional cost.

10. What about dental wastes?

Dental Wastes

The Utah Dental Association (UDA) developed best management practices for the management of dental wastes in collaboration with the Utah Department of Environmental Quality (DEQ) and local jurisdictions such as CCRWTF. This voluntary program encourages the recycling of mercury, amalgam, silver, and lead.

Silver Recovery Program
The Cedar City Pretreatment Department strives to maximize the operating efficiency of the Cedar City Regional Wastewater Treatment Facility, (CCRWTF) by regulating the types and quantities of pollutants that enter the public sewer system. Silver has become a substance of concern and is targeted for reduction by the Pretreatment Program. The Pretreatment Department has developed a Silver Reduction Program to reduce the level of silver coming into the CCRWTF.

Permit?
The goal of the silver reduction program is to provide education and technical assistance to photo and X-ray film processors to reduce silver entering the wastewater treatment system. Your cooperation in the silver reduction program is essential to prevent the need for more costly regulation. The Pretreatment department prefers to implement a program relying on the voluntary adoption of Best Management Practices (BMPs) to capture silver at the source, rather than permitting, monitoring and inspecting waste generators. The effective management of silver-bearing waste through the use of sound, BMP-based pretreatment practices can save time and money for photo and X-ray processors and Clean Water Services.

Why recover silver from photographic wastes?
Processing photographic film, x-ray, and photographic prints produces wastes containing high levels of silver. Silver is highly toxic to aquatic organisms. Photo processing waste may contain silver concentrations as high as 15,000 parts per million (ppm) before pre-treatment Wastes containing more than 5 ppm of silver are classified by the U.S. Environmental Protection Agency as hazardous waste. Disposing of silver into the public sanitary sewer system wastes a valuable resource that can be conserved. Recovering silver from photo processing waste streams converts a potential source of pollution into a potential source of revenue. Recovered silver is marketable and can be profitable. Silver recovery is beneficial to both photo processors and the environment.

Objectives of the Silver Pollution Prevention Program:
• Reduce silver coming into the public sanitary sewer system
• Minimize cost to industry
• Improve silver recovery and resource conservation
• Avoid the need to issue costly monitoring-based permits

11. What about paint waste?

Why is paint waste a problem?
All painting jobs create wastes that can harm humans, waterways, fish and other wildlife if handled or disposed improperly. Paints and paint waste can enter storm drains from runoff or improper disposal. Storm drains carry untreated pollutants directly into local streams and rivers, harming aquatic plants, animals, fish and those who eat the fish.

Why should you be concerned?
Aside from causing environmental damage, improper disposal violates Federal, and Utah State Regulations of which specifically prohibit the improper disposal of wastes and contamination of waters and provide for civil and criminal penalties for violators. Most painters manage wastes responsibly, but sometimes disposal options can be confusing. This brochure is designed to help you prevent, reduce, recycle or safely dispose of common painting wastes. The result will be happier customers who appreciate your concern for their property and a safer environment.

What is paint waste?
• Solvents (water, mineral spirits, toluene)
• Oil-based paint
• Latex paint
• Rags
• Paint chips/dust
• Paint and solvent containers

What can you do with usable leftover paint?
• Check into donating leftover paint to local theaters, schools, clubs or churches.
• Give small amounts of paint left over at the end of a job to the customer for touch up.
• Combine light-colored leftover paints for use as primer on future jobs.
• Dispose of unwanted oil-based paint at a permitted hazardous waste management facility.

Clean-up do’s
• Allow paint solids in used solvents to settle so the clear portion can be poured off and reused.
• Dispose of spent solvents at a permitted hazardous waste management facility.
• Use the least toxic cleanup solvent available.

Clean-up don’ts
• Don’t pour oil-based or latex waste paint or clean-up materials onto the ground.
• Don’t pour any paint or clean-up materials into storm drains, ditches, gutters, catch basins, dry wells, creeks or other surface water drainage.
• Don’t (unless authorized to do so from your local Solid Waste Authority) put liquid paint, solvent or clean-up waste in garbage cans or dumpsters.

Other paint job waste
• Remove lids from empty latex containers and allow the contents to dry out. Dispose of lids and dry containers in the garbage.
• Allow rags to dry thoroughly and dispose in the garbage.
• Dispose of paint chips and dust properly. For information, contact the Utah Department of Environmental Quality (DEQ).
• Most paint strippers are hazardous and should be disposed as hazardous waste.

Common sense tips and guidelines
• Purchase only the amount of paint needed for each job.
• Use latex paint whenever possible.
• Use tarps and drip pans to collect paint and solvent spills.
• Keep containers tightly sealed when not in use to avoid spills.
• Avoid contaminating ground surface with paint chips and dust.
• Use high-efficiency spray guns to minimize overspray.
• Train employees and subcontractors to handle paint waste properly.
• Store leftover latex paint, oil-based paint and solvents separately in original or clearly marked containers.
