Dear Mike:
You and your staff do a very good job of keeping the public informed. However, in the above case I feel that you should have placed a warning on the e-mail.
The warning is to the effect that the above document is obsolete, incorrect, antiquated (Too old to be fashionable, suitable, or useful; outmoded). It lacks “scientific method”
scientific method n. 1. The principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or falseness of the hypothesis, and a conclusion that validates or modifies the hypothesis.
For the reader the first clue that the site is inaccurate and should be taken with a grain of salt should be when the incorrect term “Stray Voltage” is used. Voltage does not harm, does not kill. Current kills.
Proof of this can be found
http://www.amasci.com/emotor/vdg.html Picture of man touching approximately 400,000 volts and still living. Thus proof that voltage does not kill.
Another hair raising experience engineeronline.ws/ vdgspheres.htm

Another clue that false information will be forthcoming are the words, “neutral to earth voltage”. This term is misused, misapplied, abused and exploited. It has little to do with the real cause, stray current, that harms humans and cows.
When one reads “interpreting the results” is another clue that the authors lack an understanding of the subject. The so-called “corrective action can be taken” described in the publication is incorrect and detrimental to both humans and cows. This has been shown in several court cases and in several technical papers presented at the Institute of Electrical and Electronic Engineers technical conferences by Donald W. Zipse.
If a person were just to look at Figure 1 and ask why would a person want to measure, voltage to a reference rod would be another clue that the following information is erroneous. Is the cow or person going to be able to contact the reference rod and any other electrical point being measured? Not unless you have an ox named Blue owned by Paul Bunyan who would be able to span the gap.
Testing performed by Mr. Lawrence C. Neubauer on over 900 dairy farms has proven what Electric Power Research Institute (EPRI) states in one of their documents that “60 % of the remaining (neutral) current flows in the earth” on the way back to the source, the substation.
An example would be when 20 amperes flows out on the single-phase conductor and only 8 amperes (per EPRI and measurements by Mr. Neubauer) flow back to the substation on the neutral conductor. That leaves approximately 12 amperes flowing over and through the earth.
Of those 12 amperes, approximately 6 amperes will flow directly into the dairy so-called equipotential plane that according the NEC will have no voltage gradient across the plane. Bull Shit. Those 6 amperes are directly connected by electrical conductive copper wires. The primary neutral of the transformer is solidly connected to the secondary neutral. The secondary neutral is connected to the service drop and the service drop neutral is grounded in the service entrance panel and connected to the equipment-grounding conductor, the green conductor in addition to being connected to the white colored neutral conductor. This ground conductor is directly and required by the NEC to be connected to the equipotential planes in both swimming pools and dairy buildings. Thus, the primary neutral current is allowed to flow unimpeded directly into your house, your swimming pool, hot tub, metal piped shower and the dairy farm.
What is devastating is the lightning arrestor is also directly connected into your home and the dairy farm. Thus, when ever the lightning arrestor fires it directs lightning current into your home and into the dairy farm. This bastardly act has been going on since 1932. The BIG SECRET OF THE UTILITIES.
Now these 6 amperes can be stopped by the insertion of a neutral blocker or a transformer that isolated the primary neutral from the secondary neutral thus blocking the direct electrical connection from the primary neutral to your home. However, this only stops a part of the stray current.
The remaining 6 amperes enters the ground from the multiple neutral to earth connection that are required to be made 4 per mile and at every transformer. Some states such as Wisconsin and I believe Idaho require about every pole to have a neutral to ground connection. They lack understanding of Ohms Law and common sense.
One dairy farmer cut all the down grounds for over a mile on each side of his dairy and the milk production increased. That is until the utility found the down grounds had been cut and repaired them.
This final 6 amperes of stray current flowing uncontrolled over the earth can only be corrected by the utilities installing, as any common sense electrician would do, an insulated and isolated neutral conductor. This third conductor on a single-phase distribution line is the same, as the NEC requires for a home or dairy farm. Since the 1920, the utilities have been installing their distribution lines with one less electrical conductor than required by common sense and saving billions and billions of dollars. This so called savings has resulted in shocking humans and cows and in my opinion several deaths.
