For the past two years my family has suffered the effects of a commercial trucking business being operated next door to us in an agricultural-residential area. We have been exposed continuously to life-threatening diesel fumes, stressful vibrations and engine noise for days on end, and the blaring of air-horns in the middle of the night. I read that the City of Hesperia is currently considering the issue of the trucking problem, and I wanted to voice the opinion of those on the front lines.

We need to bring our city codes up to date. Our municipal idling restriction for commercial vehicles is currently 15 minutes and must be revised to meet State requirements as detailed in the California Code of Regulations, Title 13, Division 3, Chapter 10, Article 1, Section 2485, titled "Airborne Toxic Control Measure to Limit Diesel-Fueled Commercial Motor Vehicle Idling." The statewide idling limit is five minutes. The California Commercial Driver Handbook 2007, published by the Department of Motor Vehicles, states on page 137: "Leaving truck and bus engines running is against the law (because it) can cause health problems like cancer, asthma, lung disease, bronchitis and heart disease."

Since Code Enforcement is already struggling to enforce the existing municipal idling restrictions; more stringent regulations will be an impossible burden. Code Enforcement offices don't enforce the law after-hours or on weekends and holidays, and that is when many truckers run their refrigeration units. This has made Hesperia a sanctuary for truckers. The City should consider banning trucks altogether just to alleviate the strain on Code Enforcement. It would eliminate all the trucking complaints and free up Code Enforcement to provide better service to the community.

A more important issue than "where and how truckers can park within city limits" (Hesperia Star, November 13, 2007) is the serious damage being done to the air by excess diesel fumes, as well as soil and groundwater contamination caused by diesel-fueled vehicles.

The City of Hesperia is allowing loaded trucks - weighting scores of thousands of pounds - to destroy our residential streets. This extra wear on our roads creates more maintenance works and consumes millions of taxpayer dollars.

The constant noise of running engines and refrigeration units is dangerous. Noise pollution is not generally acknowledged as a health issue, and yet it is. Lyall Watson, in his book Supernature (Coronet Books, Hodder Paperbacks Ltd., London, 1973), states: "The British Acoustical Society has become concerned about the low-frequency vibration produced by motor vehicles running at sustained speed. These "infrasound's" are at the level of 10 to 20 cycles per second, which is below the limit of human hearing, but they can affect us in the same way as flickering lights. The Society warns that these sounds can produce symptoms of recklessness, euphoria, lower efficiency, and dizziness due to loss of balance." This is a serious issue for both humans and animals. Horse & Rider magazine (October 2005, p.29), in an article on horse health, warns of exposing animals to continuous noise: "Horses are hard-wired to listen for - and react to - warning noises that may indicate a predator is nearby. Even soft music contributes to existent background noise and may force your horse to concentrate harder to separate out worrisome sounds. This could cause him to sleep less, eat less, worry more - or develop neurotic stable vices." Truckers park mostly in agricultural zones because of the lot sizes; therefore thousands of Hesperia's animals are affected.

The best solution to all of the problems created by heavy commercial vehicles is to ban them from parking in the city.
