Understanding Local FOG Regulations and Compliance

Hillsboro's FOG control program is designed to protect the city's wastewater infrastructure. The rules are clear: all food service establishments must have properly sized and functioning grease interceptors (the common term for larger outdoor units) or grease traps (typically smaller, indoor units) ^{1 2}. Compliance hinges on more than just having the equipment; it requires diligent upkeep. Key mandates include ensuring the unit is easily accessible for service providers and inspectors at all times and maintaining detailed service records that include photos, pump-out reports, and waste manifests ^{3 4}. Perhaps most critically, the use of chemical or biological additives designed to emulsify or dissolve FOG is generally prohibited, as they simply push the problem further down the sewer line where it can re-solidify and cause clogs ^{5 6}. Proper physical removal of FOG and solids through pumping is the only accepted method.

The Critical Role of Documentation

In the event of an inspection, your service records are your proof of compliance. Authorities can request documentation showing a consistent history of maintenance. Without it, your business may be cited even if the trap appears functional at that moment. Developing a relationship with a licensed, reputable service provider who understands local reporting requirements is a crucial step in building this compliance portfolio ^{1 3}.

Establishing Your Cleaning and Inspection Schedule

Your required maintenance frequency is not one-size-fits-all; it is primarily determined by the type and size of your interceptor and your kitchen's FOG production volume. The City of Hillsboro and CWS guidelines provide clear baselines ^{1 5}:

• Hydromechanical Grease Interceptors (HGI): These are typically smaller, indoor units. They must be cleaned at least every 30 days, or when FOG and solids accumulate to 75% of the unit's capacity ^{5 7}.
• Gravity Grease Interceptors (GGI): These are larger, often underground, outdoor tanks. They require cleaning at least every 90 days, or when 25% full ^{1 8}.

High-volume kitchens, such as those in large restaurants or institutional cafeterias, may need service more frequently than these minimums. It is the business owner's responsibility to monitor accumulation and adjust the schedule accordingly. Furthermore, pre-cleaning scraping of dishes and cookware is a vital daily practice that significantly reduces the load on your interceptor, extending time between services and reducing costs ⁹.

The Inspection Imperative

Scheduled pumping should always be accompanied by a thorough inspection. After a professional cleaning, a staff member should visually verify that all FOG and solids have been removed and that the baffles and flow controls are intact and functioning ⁸. This simple internal check can catch small issues before they lead to compliance failures or inefficient operation.

Consequences of Non-Compliance: Fines and Liability

The enforcement of FOG regulations in Hillsboro is taken seriously. City and CWS staff conduct inspections to ensure interceptors are properly maintained and functioning ^{1 10}. Violations can range from minor to severe:

• Citations and Fines: Initial violations typically result in warnings or fines. Repeated non-compliance leads to escalating penalties.
• Operational Shutdowns: In cases of severe neglect, such as a grease interceptor bypassing FOG directly into the sewer, authorities have the power to suspend a business's sewer service or even shut down operations until the issue is corrected and proven to be resolved ¹¹.
• Financial Liability: If a sewer backup or overflow is traced back to FOG discharged from your establishment, your business can be held financially responsible for all cleanup costs, public utility repairs, and any resulting environmental damages ^{11 10}.

Understanding Service Costs and Provider Selection

Investing in routine grease interceptor maintenance is far less expensive than dealing with the consequences of neglect. Costs in the Hillsboro area vary based on the type and size of your unit, its location, and its condition.

• Routine Indoor Grease Trap (30-200 gallon): A standard service for a regularly maintained indoor unit typically ranges from $125 to $250 per cleaning. Many providers offer discounted rates for businesses on a scheduled maintenance contract ^{12 13}.
• Routine Outdoor Grease Interceptor: Pumping a larger outdoor interceptor is more involved, with costs generally starting around $300 and can exceed $1,000 per service depending on size and accessibility ^{14 15}.
• Emergency or Neglected Trap Cleaning: If a trap has been ignored, the cost can be two to three times higher than routine service. Heavy buildup of solidified FOG and solids requires more labor, time, and disposal fees ^{12 16}.
• Compliance Reporting: Many professional services include the preparation and submission of the required compliance report to the City or CWS for an additional base fee, often around $105 or more, which is a valuable service for ensuring your paperwork is handled correctly ¹⁴.

When selecting a service provider, ensure they are licensed, insured, and familiar with Hillsboro and CWS regulations. Ask if they provide detailed documentation, including waste hauling manifests and before/after photos, which are essential for your records.

Building a Proactive FOG Management Plan

A successful strategy extends beyond just scheduling pump-outs. It involves a holistic approach:

1. Staff Training: Educate every kitchen employee on the importance of FOG control. Implement practices like scraping food waste into trash bins before dishwashing and using sink strainers.
2. Partner with a Professional: Establish a contract with a reliable grease trap cleaning service that understands local codes. A consistent schedule prevents emergencies.
3. Maintain Impeccable Records: Keep a dedicated log or digital folder for every service report, invoice, and manifest. This is your primary evidence of compliance.
4. Conduct Regular Visual Checks: Assign a manager to briefly inspect the interceptor after each professional cleaning and periodically between services to monitor accumulation rates.

By taking these steps, Hillsboro restaurant owners can turn grease trap maintenance from a regulatory burden into a routine part of successful, sustainable business operations, ensuring smooth service and protecting the community's water infrastructure ^{1 3}.
