Utility Addresses Lead Paint Concerns

Residents of a California town are sounding an alarm about the dangers of flaking lead-based paint in their neighborhood. However, unlike so many others regarding lead-based paint, those concerns are not about paint in their homes.

Paint has been found to be flaking off power-line towers and falling into residents’ properties, according to a Contra Costa Times report on Sunday (Dec. 6).

Their concerns center on health risks the fallen paint chips could pose to children and at-risk adults in the area.

Peeling, Flaking Paint

Citizens of Saranap, CA, near Walnut Creek, are questioning the paint job on the transmission towers, owned by Pacific Gas & Electric (PG&E), that run through their town.

Residents of Saranap, CA, have raised concerns over paint flaking off power-line towers (not shown) and falling into their properties, according to a Contra Costa Times report.

One resident expressed concern over a 60-foot tower on his property that showed paint peeling from its base. While paint is not flaking off the whole tower, sections higher up appear not to be fully or evenly covered.

The paper noted that several towers show red paint visible through the silver topcoat.

They took their concerns to PG&E, who is said to have a program in place to better understand the lead content on the towers, as well as to address the issue when it comes to the safety of their workers and the area residents.

Addressing the Issue

Tamar Sarkissian, a spokeswoman for PG&E, told the paper that while many of their towers are galvanized and uncoated, others are painted. If those towers were painted prior to 1978, she said, they may be coated with paint that contains lead.

She indicated that the company does check the transmission towers for lead prior to work, if peeling paint is identified or if a customer notifies them, but, she noted, notifications from property owners are “very rare.”

“If we find that a tower does have lead paint and may be causing a release of lead paint dust…we also test the soil around it,” Sarkissian added.

When testing reveals lead contamination, the utility takes the necessary steps to protect “the health and safety of our customers, employees and the environment," she said.

One resident who spoke to the paper confirmed that PG&E did remove and replace contaminated soil at the base of a nearby tower, although he hasn’t been able to attain the same treatment for a tower on his property.

According to PG&E, while many of their towers (not shown) are galvanized and uncoated, others are painted. If painted prior to 1978, they may be coated with a lead-based paint.

Sarkissian said that when paint is “intact and well bonded to the structures” it is not considered a hazard.

PG&E did not respond to a query for additional information on the coatings and repainting process.

Risks of Lead in Paint, Soil

Although the use of lead-based paints in housing were prohibited after 1978, paint and dust from nearly 40 years ago still can be found in more than 30 million homes, according to the EPA.

While major sources of lead exposure to children include lead-based paint and lead-contaminated dust in deteriorating buildings, children can also be exposed to lead from additional sources including contaminated drinking water, take-home exposures from a workplace, and lead in soil, according to officials.

Soil, yards and playgrounds can become contaminated when exterior lead-based paint from structures or buildings flakes or peels and gets into the soil.

Lead in soil can be ingested as a result of hand-to-mouth activity that is common for young children and from eating vegetables that may have taken up lead from soil in the garden. Lead in soil may also be inhaled if re-suspended in the air, or tracked into a home and then spreading the contamination, the EPA says.

Even low levels of lead found in blood can cause behavior and learning problems; lower IQ and hyperactivity; slowed growth; hearing problems; anemia; and in rare cases, seizures; coma; and even death.

Lead is particularly dangerous to children because their growing bodies absorb more lead than adults do and their brains and nervous systems are more sensitive to the damaging effects of lead.

In addition to children, a pregnant woman’s exposure to lead is of concern because it can lead to serious effects for both her and her developing baby, including reduced growth and premature birth.

Congress has passed a number of laws related to lead that address lead in paint, dust and soil; lead in the air; lead in water; and disposal of lead wastes.

Editor's note: content was altered to clarify the ban of lead paint use in housing.

I'd recommend reviewing the statement that all lead-based paints were banned in 1978. It's my understanding that the regulation introduced only restricted the use of lead in consumer products. Products, such as industrial paint, do not require confirming with the mentioned regulation. There are industrial, inorganic zinc coatings that I've seen PDS for that show up to 2,000 ppm of lead much later than 1978 and even some up to 1% lead. I believe the statement that lead-based paints and products no longer exist is slightly misleading. It just happens to be outside of the concerns for most products that you'd find at your local Lowes or equal.

Michael is spot on with his comment, automotive paints up til the 2000s had lead in them.

It also depends on the jurisdiction. In Canada, the Surface Coating Materials Regulation restricts lead to 90 mg/kg (ppm) in paint...It's not much, but it isn't a total ban either. I believe the US has similar types of regulations...not a complete ban, but very low levels that are not believed to have health impacts.

Lots of things often still have lead at around the 1% level. Galvanizing. The keys in your pocket. Brass plumbing fixtures unless they are VERY new (and now limited to a quarter %) - don't let your infant chew on your keys, by the way.

So, i myself being a Lead Renovator, Bridge Painter, and Nclear Coatings worker for the IUPAT can shed some light onto the regulations that are in place. Because Lead is found in many applications throughout the industry like casting, vitrification, technology, you get it. The US EPA , OSHA, and department of health got together and formed a standard that calls out, when Lead is considered hazardous? Though Lead is always hazardous, they also considered a limitation level. Lead is considered a hazard if there are more than 40 micrograms of lead dust per swuare foot on floors, or 250 micrograms of lead in dust per square foot on interior window sills, or if there are more that 400 parts per million of lead in the bare soil in children's play areas or more thatn 1,200 parts per million of lead in bare soil in the rest of the yard or area around the building. So with that, Lead is not completely banned due to the necessity of it in some fields and processes that we have today. And if you are asking what this has to do with the coatings containing Lead? It depends on what kind of lead is in the coatings because there are what could be called "sytnthetic forms", then there is Lead Acetate (most commonly used in paints as a drier), Lead Phosphate, and Lead salts. Like I said, it depends on what kind is in the product. Hope this helps and I didn't ramble too much!! IUPAT DC 5 Local 300
