Williams Transco Booster Station and others emit formaldehyde

The Williams Transco pipeline runs from Texas to New York and passes through states like Georgia. There are 44 compressor stations along the way. In Comer, Georgia, the pipeline compressor emits 4,827 tons of pollutants, including 185 tons of formaldehyde, into the air each year. This compressor station is on the Georgia State Hazardous Site Index because of past soil contamination. This information comes from the Georgia Environmental Protection Division.

The Comer booster station is on the state Hazardous Site Index because of soil contamination by PCBs, a chemical commonly used as coolants and lubricants in transformers.
Leaks from the station come from faulty pump seals, valves, flanges, compressors and turbines as well as emergency shutdowns and maintenance, the state Environmental Protection Division said.
Williams Transco's station in Comer is one of 44 compressor stations along the pipeline, which runs from Texas to New York.
The station emits an estimated 4,827 tons of pollutants into the air each year, according to the EPD, including 185 tons of formaldehyde.
Formaldehyde, according to the EPD, has been found to cause cancer in rats and may cause cancer in humans.
The pipeline also emits 4,156 tons of nitrogen oxides, which the U.S. Department of Health and Human Services says are known to cause respiratory illness.

ConocoPhillips will implement specialized equipment to cut the release of carbon monoxide and other air hazards such as formaldehyde from the compressor station engines, the EPA engineer said.

I found many more but you get the picture.

According the the National Cancer Institute, Formaldehyde exposure is associated with increased risk of cancers of the blood and lymphatic system. This includes leukemia.

Results from an ongoing study of workers employed at plants that used or produced formaldehyde continue to show a possible link between formaldehyde exposure and death from cancers of the blood and lymphatic system, particularly myeloid leukemia. The report, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, provides an additional 10 years of follow-up data to build on previous findings from this study. The report appeared online May 12, 2009, and in print May 20, 2009, in the Journal of the National Cancer Institute.

Looking at the Flower Mound Kleinfelder Air Quality Tests, I did not see where testing was done for formaldehyde. It seems that chemical and gas drilling go together.
