- To protect the City of Loveland's sewer system from pollutants that could interfere with the collection system or wastewater treatment plant (WWTP) processes.

- To protect city employees from potentially harmful discharges.
Clean Water Act
In 1972, the United States Congress pass the Water Pollution Control Act which stipulated broad national objectives to “restore and maintain the chemical, physical, and biological integrity” of the Nation's waters (33 U.S.C. 1251). The Water Pollution Control Act was amended in 1977 and re-titled the “Clean Water Act” (CWA).
Within the CWA, Congress established the Environmental Protection Agency (EPA). The EPA established the “General Pretreatment Program Regulations” in 1978. These regulations require many Publicly Owned Treatment Works (POTWs) nationwide, including the City of Loveland, to administer an EPA approved Pretreatment Program. The City of Loveland’s Pretreatment Program was approved by the EPA on September 9, 1985.
Chapter 13.10 of the Loveland Municipal Code sets forth the requirements for industrial users (IUs) of the City’s sewer system. All industrial users must provide wastewater treatment as necessary to comply with the ordinance.
Users classified as a significant industrial user (SIU) are required to obtain a wastewater discharge permit.
Pollution Prevention Act
In the Pollution Prevention Act of 1990, Congress declared it to be the policy of the United States that:
- Pollution should be prevented or reduced at the source whenever feasible;
- Pollution that cannot be prevented should be recycled in an environmentally safe manner, whenever feasible;
- Pollution that cannot be prevented or recycled should be treated in an environmentally safe manner whenever feasible; and
- Disposal or other release into the environment should be employed only as a last resort and should be conducted in an environmentally safe manner.
The City of Loveland’s Industrial Pretreatment Program agrees with this policy and recommends that Industrial Users voluntary utilize pollution prevention and waste minimization techniques and/or alternatives where feasible to eliminate or reduce the amount of pollutants entering the sewer system.
Wastewater discharges containing fats, oil, and grease (FOG) create restrictions in the sanitary sewer collection line, lead to sewer backups, and create operational problems at the City’s wastewater treatment plant. The City has a responsibility (under Federal and State clean water laws) to prevent grease related problems and has information available to residential and commercial customers.
Grease Removal Devices
Food service establishments are required to install and maintain a grease removal device. A grease removal device is either a grease trap or grease interceptor.
- Grease Trap. A grease trap is a device usually found inside a facility. This type of device requires frequent cleaning (daily to monthly).
- Grease Interceptor. A grease interceptor is typically located outside and underground. This device is serviced by a waste hauler since the volume is larger. Due to the variety of food service establishments and interceptor size the cleaning frequency varies.
Proper operation and maintenance of a grease removal device is required by city code 13.10.305. To ensure a grease removal device is being properly maintained, the a food service establishment employee should verify the contents were totally removed and that interior components (piping, baffle, etc…) did not get damaged or knocked off during the cleaning process. It is the establishments responsibility to ensure proper measures are in place to comply with city codes and standards.
The Pretreatment Program conducts periodic inspections to determine if an establishment is maintaining the grease removal device frequently enough so not to create a grease problem.
Reports must be sent to the City within 30 days after the grease removal device is emptied. A record (log, manifest, invoice) must also be kept on-site in the event an inspection is conducted
Hazardous Waste Discharged to Sanitary SewerIndustrial users must notify the City of Loveland, EPA Region VIII Waste Management Division Director, and the Colorado Hazardous Waste Management authorities in writing of any discharge of a substance, which, if otherwise disposed of, would be a hazardous waste under 40 CFR 261.
An industrial user is any non-residential user that discharges non-domestic wastewater to the City of Loveland’s sanitary sewer system.
An industrial user is generally exempt from the requirements during a calendar month in which they discharge no more than 15 kilograms (33 pounds) of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e).
Hazardous Waste Disposal OptionsLarimer County. Larimer County has a program in place to assist small businesses in disposing of hazardous waste they generate. The "Business Hazardous Waste Assistance and Education Program" (or BHAPE) provides a safe and affordable disposal/recycling option for Conditionally Exempt Small Quantity Generators (CESQG) in Larimer County. This voluntary program is fee based and operated at the Household Hazardous Waste Facility located at the Larimer County Landfill.
The State of Colorado Hazardous Materials and Waste Management Division’s Generator Assistance Program can assist a business in complying with regulatory requirements. For more information contact the Division at 303-692-3300.
The City of Loveland’s Wastewater Treatment Plant (WWTP) is primarily designed for the treatment of domestic wastewater. Typical pollutants found in domestic wastewater are ammonia, biological oxygen demand (BOD) and total suspended solids (TSS).
The WWTP also accepts wastewater from non-domestic sources and can regulate the wastewater from these sources in order to comply with its (NPDES) discharge permit requirements. Certain types of commercial and industrial businesses discharge wastewater that contain pollutants above, or in addition to, domestic contributions.
The intent of the High Strength Sewer Surcharge is to recover the costs of treating wastes above domestic contributions. When a determination is made that a business falls under the sewer surcharge, the business is notified of this, provided an explanation of the surcharge fee, informed that the surcharge amount will be added to their monthly utility bill, and provided an opportunity to contest the charge.
The High Strength Sewer Surcharge ordinance is located in Section 13.08.101 of the Loveland Municipal Code and can be traced back to Ordinance 1536 (1976).
The City requires some business to install a treatment device (grease interceptor or oil/sand interceptor) so that certain pollutants (e.g.; sand, petroleum oil, fats, oil and grease) are removed from the wastewater prior to discharge. At a minimum, this reduces sewer blockages, sewer overflows and City maintenance. The surcharge customer is billed for the cost of treating excessive BOD and TSS. Installing a treatment device does not remove a business from paying the surcharge.

- Use a Fat Trapper to keep fat, oil, and grease out of sewer lines.
- Fats, oils, and grease can plug the City's sewer lines and cause a sewer backup that can damage your home.
- Purchase a Fat Trapper at the Service Center, 200 North Wilson Avenue or at the Utility Billing Office at 500 East Third Street.
