San Bernardino County

It depends where in the county your site sits, because San Bernardino is the largest county in the United States by area and it spans two regulators.

The valley, which is where nearly all commercial property is, sits with the Santa Ana Regional Water Quality Control Board. That covers Ontario, Fontana, Rancho Cucamonga, Rialto, Redlands and San Bernardino itself. The desert and mountain communities, including Victorville, Hesperia, Barstow and Big Bear, fall instead to the Lahontan Regional Water Quality Control Board.

The practical difference shows up in what the two boards care about. Lahontan governs a region where water is scarce and receiving waters are sensitive, and it is correspondingly firm about discharges. A practice that passes without comment in Fontana may not in Victorville.

We contain and recover wash water on every site regardless of which side of the line it is on, capture solids at the drain inlet, and log the method and disposal for each visit. Read what BMP (Best Management Practices), MS4 (municipal separate storm sewer system) and NPDES (National Pollutant Discharge Elimination System) require of a private property owner.

This county is the freight floor of Southern California, and its buildings show it.

Distribution property here collects a specific and stubborn film: diesel exhaust, tire rubber and brake dust ground into concrete by constant trailer movement, then bound in place by heat. Cold water moves it around. Hot water and a surface cleaner lift it.

The characteristic problems on Inland Empire property are these:

• Black tire tracking and turning scuffs across truck courts and dock aprons
• Diesel soot staining on dock doors, bollards and the lower few feet of tilt-up wall
• Hydraulic and fifth-wheel grease at trailer parking positions
• Windborne dust on every windward elevation, redeposited after each Santa Ana event

Truck court cleaning is the dominant need in this county, and it is a hot water job almost without exception.

• Logistics & Distribution The Ontario, Fontana, Rialto and Redlands warehouse corridor
• Cold Storage & Refrigerated Warehouse Facilities where dock hygiene is an audit item, not an appearance one
• Airports & Aviation Cargo and ground-handling areas around Ontario International
• Industrial & Manufacturing Production yards and equipment pads
• Commercial & Retail Property Centers and plazas across the valley cities
• Storage Facility & Self-Storage Drive aisles, roll-up doors and frontages

Coverage concentrates on the valley, where the commercial property is, and extends to the High Desert on program work.

• Why does cold water not clean our truck court? Because the soil is oil-based. Diesel residue, tire rubber and hydraulic grease need heat to break their bond with the concrete, so cold water spreads the film into a wider grey stain rather than removing it.
• Can a distribution center be cleaned without stopping trailer movements? Yes. Yards are worked section by section around the dock schedule, generally overnight or during a shift change, so doors and lanes stay available.
• Do the High Desert sites follow the same rules as our valley sites? No. Valley property answers to the Santa Ana board and High Desert property to the Lahontan board, which is stricter about discharges. We work to the stricter standard everywhere so a single practice covers both.
• How often should a truck court be cleaned? Most high-throughput yards hold up on a quarterly cycle, with dock aprons and trailer positions needing attention more often. We set the interval from your traffic volume rather than from a standard package.
