They do other things like check ground water for contaminates, and lake water for bacteria, and a host of other things. Hydrochloric Acid is used to balance the PH of the water. As far as I know, George Pepple was the only one at the plant with a PhD, which gave him the title of Doctor. No one called him Dr. Pepple (which sounds like a soda pop). We either called him George or Pepple (Pep Lee) or both. He had a sort of Einsteinian simplicity about him. To me he was the perfect combination of Einstein and Mr. Rogers from “Mr. Roger’s Neighborhood”:
Albert Einstein
Mister Rogers
One other thing I would like to add about George was that he developed a special process for Cupric chloride leaching of copper sulfides. This was a patented process (1982) which is now owned by the Phelps Dodge Corporation which is a copper and gold mining company. As humble as George Pepple was, he never mentioned this to anyone at the plant as far as I know.
When he would page someone on the PA system (gray phones), he would always do it in a straight monotone voice. putting no accents on any of the words and he would always repeat his page twice. Like this: “PaulMullonLineOne. PaulMullonLineOne.”
Gaitronics Gray Phone
Before I get to the point where George is dancing in the acid, I first need to tell you about Gary Michelson, since he had a role to play in this jig. In an earlier post: In Memory of Sonny Karcher, A True Power Plant Man, I remarked that Sonny Karcher had told people when he introduced me to them that I was going to college to learn to be a writer (which wasn’t exactly true. The writing part I mean…. I was going to college… and.. well… I am writing now), and that I was going to write about them. In doing so, some people took me in their confidence and laid before me their philosophy of life.
Jerry Mitchell being one of them (as you can read in an earlier post about “A Power Plant Man Becomes an Unlikely Saint“). Jerry had filled me with his own sense of humility, where it was important to build true friendships and be a good and moral person. His philosophy was one of kindness to your fellow man no matter what his station in life. If there was someone you couldn’t trust, then stay clear of them.
Gary Michelson was another person that wished to bestow upon me his own personal wisdom. We worked for about 3 days filtering the hydraulic oil in the dumper car clamps and in the coal yard garage. While there, he explained to me why it was important to be the best in what you do. If you are not number one, then you are nobody. No one remembers who came in second.
He viewed his job performance and his station in life as a competition. It was him against everyone else. He didn’t care if he didn’t get along with the rest of the people in the shop (which he didn’t) because it is expected that other people would be jealous or resentful because he was superior to them.
According to Gary his family owned part of a uranium mine somewhere in Wyoming or Montana. He thought he might go work for his father there, because truly, he was not a True Power Plant Man. He reminded me slightly of Dinty Moore. Like a lumber Jack.
Dinty Moore
As I mentioned in the post about the “Power Plant Genius of Larry Riley“, Gary Michelson had the title “Millwright”. Which no one else in the shop seemed to have. He had been certified or something as a Millwright. Gary explained to me that a Millwright can do all the different types of jobs. Machinist, Mechanic, Pipe fitter, etc.
I remember him spending an entire week at a band saw cutting out wedges at different angles from a block of metal to put in his toolbox. Most mechanics at this time hadn’t been issued a toolbox unless they had brought one with them from the plant where they had transferred. Gary explained to me that his “superiority was his greatest advantage.” Those aren’t his words but it was basically what he was saying. That phrase came from my son who said that one day when he was imitating the voice of a video game villain named Xemnas.
Filtering the hydraulic oil through the blotter press was very slow until we removed most of the filters.
An Oil Blotter Press Similar to the one we had, but our press did not have “NAKIN” written on it.
It was a job that didn’t require a lot of attention and after a while became boring. That gave me more time to learn about Gary. He filled the time with stories about his past and his family. Since I hadn’t met Ramblin’ Ann at this point (See the post “Ed Shiever Trapped in a Confined Space with a Disciple of Ramblin’ Ann“), I was not able to contribute my share. In the middle of this job we were called away to work on a job in water treatment where a small pump needed to be re-installed.
During this time at the plant every pump, fan, mill and turbine were brought to the maintenance shop and disassembled, measured, cleaned, honed and reassembled before the plant was brought online for the first time. This is called doing a “check out” of the unit. The electricians would check every motor, every cable and every relay and alarm. The Results team (Instrument and Controls as they were later called) would check out the instrument air, the pneumatic valves and the control logic throughout the plant.
Gary had me go to the tool room and get some rubber boots and a rain suit. When we arrived at the water treatment building George Pepple was there waiting for us. The pump was in place and only the couplings needed to be connected to the acid line. Gary explained to me as he carefully tightened the bolts around the flange that you had to do it just right in order for the flange to seat properly and create a good seal. He would tighten one bolt, then the bolt opposite it until he worked his way around the flange. He also explained that you didn’t want to over-tighten it.
Pipe Flange
Anyway. When he was through tightening the couplings I was given a water hose to hold in case some acid were to spray out of the connections when the pump was turned on. After the clearance was returned and the operator had closed the breaker, George turned the pump on. When he did the coupling that Gary had so carefully tightened to just the right torque using just the right technique sprayed a clear liquid all over George Pepple’s shoes.
Gary quickly reached for the controls to turn off the pump. I immediately directed the water from the hose on George’s shoes while he began to jump up and down. In last week’s post I explained that when I was working in the River Pump forebay pit shoveling sand, there was a point when I realized that I was covered from head to foot with tiny crawling bugs, and I felt like running around in circles screaming like a little girl (See “Power Plant Men Taking the Temperature Down By The River“).
If I had done that, I probably would have been singing the same song and dance that George Pepple was doing at that moment. Because he indeed was screaming like a little girl (I thought). His reaction surprised me because I didn’t see the tell tale signs of sizzling bubbles and smoke that you would see in a movie when someone throws acid on someone. I continued hosing him down and after a minute or so, he calmed down to the point where he was coherent again. He had me run water on his shoes for a long time before he took them off and put on rubber boots.
After hosing off the pipes, Gary took the coupling apart and put the o-ring in place that he had left out.
Rubber O-Ring
I made a mental note to myself. — Always remember the o-ring.
Besides those two jobs, I never worked with Gary Michelson again. When I returned the next summer Gary was no where to be found. When I asked Larry Riley about it, he just said that they had run him off. Which is a way of saying… “He ain’t no Power Plant Man.”
George Pepple on the other hand was there throughout my career at the power plant. He was a True Power Plant Man, PhD! When George was around you knew it was always “A wonderful Day in the Neighborhood”. When I would hear George Pepple paging someone on the Gray Phone (the PA system) in his own peculiar way, I would think to myself… “I like the way you say that.” (As Mr. Rogers used to say). I will leave you with that thought.
Since I originally wrote this post in 2012, George Pepple has died. He died on October 28, 2019. I was able to find his picture from his Obituary site. Here it is. See what I mean about a cross between Einstein and Mr. Rogers?

Funny isn’t it, how the ones that are the best (in their own minds) do stupid stuff like forgetting the O-ring. Apparently they can’t see for all the jaw-flapping involved in patting themselves on the back. Not that I haven’t had a few days I’d rather not talk about too.

Cracking a Boiled Egg in the Boiler and Other Days You Wish You Could Take Back

It seemed that during the days when I was a summer help, and even when I was a laborer on Labor Crew that in order to be promoted you had to come up with one grand idea that set you apart from the others and that also failed miserably.
It was said that the electrical supervisor there before Leroy Godfrey (I can see his face, but his name escapes me. Jackie somebody), was promoted to that position after he caused the destruction of one of the Intake pump motors (a very large pump that can pump 189,000 gallons of water per minute).
To name a couple of minor “Faux Pas” (how do you pluralize that word? I don’t know — Faux Pauses?), let me start out with the least embarrassing and less dangerous and work my way to the most embarrassing and most dangerous of three different stories of someone thinking out of the box while leaving common sense somewhere behind and maybe wishing they could take back that day.
The first two stories both involve the Electrical Supervisors of two different Power Plants.
Tom Gibson, the Electrical Supervisor from our plant was trying to find a way to keep moisture out of the Bottom Ash Overflow Sump Pumps. This was a recurring problem that required a lot of man hours to repair. The bell shaped pump would have to be pulled, the motor would have to be disassembled and dried, and new seals would have to be put in the pump to keep it from leaking.
A Bottom Ash Overflow Sump Pump or BAOSP for Short
So, Tom Gibson decided that he was going to fill the motor and pump cavity with turbine oil. All electricians knew that oil used in turbines is an insulator so electrically it wouldn’t short anything out. But something in the back of your mind automatically says that this isn’t going to work.
I remember helping to fill the motor up with oil in the Maintenance shop and hooking up some motor leads from the nearby Maintenance shop 480 volt switchgear. Needless to say, as soon as the pump was turned on, it tripped the breaker and oil began leaking from the cable grommet.
That’s when common sense tells you that the all the oil causes too much drag on the rotor which will cause a 480 motor to trip very quickly. After removing some of the oil and trying it again with a larger breaker and still having the same result Tom was satisfied that this just wasn’t going to work.
The pump and motor was sent away to a nearby electric shop to be rewound and other ways were developed by the help of our top notch machinist genius Randy Dailey who came up with a positive air pressure way to keep water out of the Bottom Ash Overflow Sump Pump and motor (also known as the BAOSP). Not much harm done and Tom Gibson didn’t feel too bad for trying something that the rest of us sort of thought was mildly insane.
The next story was told to me by my dear friend Bob Kennedy when I was working at a Gas Powered Plant in Midwest City and he was my acting foreman and backed up by the rest of the electricians as they sat there nodding their heads as Bob told this story.
So I didn’t witness this myself. This one was a little more dangerous, but still thankfully, no one was hurt. Ellis Rooks, the Electrical Supervisor needed to bump test a 4200 Volt motor and wanted to do it in place (bump testing is when you switch something on and off quickly. Usually to see which way it turns). For some reason he was not able to use the existing cables, maybe because that was the reason the motor was offline. Because one of the cables had gone to ground.
So, he decided that since the motor only pulled 5 to 10 amps he could use #10 wire (the size wire in your home) and string three of them (for the three phases of the motor) from the main High Voltage switchgear across the turbine room floor over to the motor. Now, most electricians know how many amps different size wires can generally handle. It goes like this: #14 – 15 amps, #12 – 20 amps, #10 – 30 amps, #8 – 50 amps and on down (smaller numbers mean bigger wires).
So, Ellis thought that since the motor only pulls around 5 amps, and he only wanted to bump the motor (that is, turn it on and off quickly) to watch it rotate, he thought that even though there was normally three 3 – 0 cables (pronounced three aught for 3 zeroes, very large wire) wired to the motor, this would be all right because he was only going to bump it.
This works when you are using is 120 or 220 volts
Needless to say, but I will anyway, when the motor was bumped, all that was left of the #10 wires were three black streaks of carbon across the turbine room floor where the wire used to exist before it immediately vaporized.
You see, common sense tells you that 4200 volts times 5 amps = 21,000 watts of power. However, the starting amps on a motor like this may be around 50 to 100 amps, which would equal 210 to 420 Kilowatts of power (that is, 420,000 watts or more than 2/5 of a Megawatt). Thus vaporizing the small size 10 wire that is used to wire your house.
I think until the day that Ellis Rooks retired he was still trying to figure out where he went wrong. There must have been something defective with those wires.
All right. I have given you two relatively harmless stories and now the one about cracking the boiled egg in the boiler. This happened when I was still a janitor but was loaned to the Labor Crew during outages. When the boiler would come offline for an outage, the labor crew would go in the boiler and knock down clinkers and shake tubes to clean out clinkers that had built up around the boiler tubes in the intermediate pressure area of the boiler.
Clinkers are a hard buildup of ash that can become like large rocks, and when they fall and hit you on the head, depending on the size, can knock you to the floor, which makes wearing your hardhat a must. Your hardhat doesn’t help much when the clinkers falling from some 30 feet above hits you on your shoulder, so I always tried to suck my shoulders up under my hardhat (like a turtle pulling in his arms and legs) so that only my arms were left unprotected.
It wasn’t easy looking like a pole with no shoulders, but I tried my best. I think Fred Crocker the tallest and thinnest person on Labor Crew was the best at this. This is the Reheater area of the boiler in the diagram below:
Diagram of a boiler
Before we could get into the boiler to start shaking tubes, the dynamiters would go in there first and blow up the bigger clinkers. So, for a couple of days some times, at the beginning of an overhaul, you would hear someone come over the PA system about every 20 minutes saying, “Stand Clear of Number One Boiler, We’re Gonna Blast!!!” This became so common to hear over the years that unless you were up on the boiler helping out, you didn’t pay any attention to it.
This is something that is only done at a Coal-fired Power Plant because Gas Plants don’t create Ash that turns into Clinkers. Maybe some Soot, I don’t know, but not Ash. Which brings to mind a minor joke we played on Reginald Deloney one day when he came from a gas plant to work on overhaul. Reggie automatically reminded you of Richard Pryor. He had even developed a “Richard Pryor” way of talking.
Richard Pryor trying to look like Reggie Deloney
We were going to work on a Bowl Mill motor first thing, which is down next to the boiler structure in an enclosed area. We brought our roll around large toolbox and other equipment over to the motor. Andy Tubbs and Diana Brien were there with Reggie and I. I think Gary Wehunt was there with us also.
When someone came over the PA system saying, “Stand Clear of Number Two Boiler, We’re Gonna Blast”, all of us dropped everything and ran for the door as if it was an emergency. Reggie, not knowing what was going on ran like the dickens to get out in time only to find us outside laughing at the surprised look on his face.
Like this
Anyway. That wasn’t the day that someone wished they could take back, but I thought I would throw that one in anyway so that now Reggie will wish that he could take back that day.
When I was on Labor Crew, and we were waiting on the boiler for the dynamiters to blast all the large clinkers, the engineer in charge, Ed Hutchins decided that things would go a lot quicker if all the laborers would go into the boiler and shake tubes while the dynamiters were setting their charges (which wasn’t the normal procedure. Normally we waited until the dynamiters were all done). Then we would climb out when they were ready to blast, and then go back in. So, we did that.
All 10 or so of us climbed into the boiler, and went to work rattling boiler tubes until we heard someone yell, “Fire In The Hole!!!” Then we would all head for the one entrance and climb out and wait for the blast.
The extra time it took to get all of us in the boiler and back out again actually slowed everything down. We weren’t able to get much work done each time, and everyone spent most of their time climbing in and out instead of working, including the dynamiters.
So Ed had another brilliant idea. What if we stayed in the boiler while the dynamite exploded? Then we wouldn’t be wasting valuable time climbing in and out and really wouldn’t have to stop working at all.
Of course, common sense was telling us that we didn’t want to be in an enclosed boiler while several sticks worth of dynamite all exploded nearby, so the engineer decided to prove to us how safe it was by standing just inside the entrance of the boiler with his ear plugs in his ears while the dynamite exploded.
The dynamiters at first refused to set off the charges, but after Ed and the labor crew convinced them (some members on the labor crew were anxious for Ed to try out his “brilliant idea”) that there really wouldn’t be much lost if the worst happened, they went ahead and set off the dynamite.
Needless to say…. Ed came wobbling his way out of the boiler like a cracked boiled egg and said in a shaky voice, “I don’t think that would be such a good idea.” All of us on the Labor Crew said to each other, “..As if we needed him to tell us that.” I think that may be a day that Ed Hutchins would like to take back. The day he learned the real meaning of “Concussion”. I think he was promoted shortly after that and went to work in Oklahoma City at Corporate Headquarters.

When you have pallets double-stacked, you should only move them about with a pallet jack. The bottom pallet – and whatever is stacked on it – is thoroughly supported. And even if the pallet jack is powered, you aren’t likely to get in trouble with rapid acceleration.
As you would with a fork lift truck.
And the double stacked pallets are truck mirrors boxed for shipment to retailers. A couple hundred mirrors. And I dumped both pallets when I went to back up and turn into the warehouse aisle.

Modern parables like these are much too good to waste! They should be included in every freshman Congressman’s Washington Welcome Kit when he first takes office and new ‘reminder’ versions again every time he wins an election. These are wonderful essays on unintended consequences, at which our Congress is among the best!

New Home in the Power Plant Electric Shop
Originally Posted January 4, 2013:
November 7, 1983 I walked into the electric shop from the Power Plant Parking Lot with Bill Rivers. Bill was an electrician that I had been carpooling with off and on for almost a year. I remember walking in the door and the first thing I noticed were two guys leaning against the counter by the coffee pot that I hadn’t seen before. They looked like a couple of Electrical Contract hands.
When I came in the door, Bill told them that I was the new electrician. They both looked very surprised. The tall one told me that his name was Art Hammond and that this was his first day as an electrician in the shop also. He had just been hired. The shorter guy introduced himself as Gene Roget (it is a French name pronounced “Row jay” with a soft J). I could tell by his shock and look of disappointment at my young appearance and obvious lack of experience that he had been expecting to be hired permanently along with Arthur.
My new foreman was Charles Foster, the person that had asked me to think about becoming an electrician in the first place. Charles was a calm mild mannered person that made it clear to me the first day that I could call him Charles, or Foster or even Chuck, but don’t call him Charlie. Ok. I made a note of that in my mind….. When the need arises to really irritate Charles, I should remember to call him Charlie. — Just a side note… That need never did arise. I did think it was funny that I had referred to my previous foreman Larry Riley as my Foster Father, and now I actually had a Foster for a Foreman. The electric shop had a short Monday Morning Safety Meeting and then I officially began my 18 year career as an electrician.
I could go on and on about how Charles Foster and I became the best of friends. I could fill up post after post of the things we did and the hundreds of conversations we had each day at lunch…. and um…. I suppose I will in good time. Today I just want to focus on what we did the first day. The first thing Charles told me after making it clear that “Charlie” was not the way to address him, was to tell me that he believed that the way I would become a good electrician was for him to not tell me much about how he would do something, but instead, he would let me figure it out myself. And if I made a mistake. That was all right. I would learn from it.
I really hated making mistakes, and I wished at the time that he would let me follow him around telling me his electrical wisdom. Finally, in my mind I thought, “Ok. If Charles didn’t mind my making mistakes, then I will try not to mind it either.” It was hard at first, but eventually, I found that making mistakes was the highlight of my day sometimes… Sometimes not… I’m sure I will talk a lot about those in the coming months.
I followed Charles up to Bill Bennett’s office. He was our A foreman, and there was a cabinet in his office where he kept all the new electrician tools. I was given a used black five gallon bucket and a tool pouch to carry my tools. Like my first day as a summer help, I had to learn the name of a lot of new tools that day. There were crimpers, side cutters, Lineman’s Pliers, strippers and Holding Screwdrivers. I was given a special electrician pocket knife and was told that I would have to keep it very sharp. I had all sizes of screwdrivers and nut drivers. I put all the tools including the tool pouch into the black plastic bucket.

Bill Bennett was a tall very thin black man. He was a heavy smoker. This showed on his face as he looked older than I thought he really was. He spoke with a gruff voice from years of smoking. He was a very likable person (like most Power Plant Men). He told me that they had tried really hard to get me in the electric shop because the two men in the corner offices really didn’t want me to move off of the labor crew. He explained that I owed my new career to Charles Foster who gallantly went to bat for me. I told him I was grateful.
I was also given a Pocket Protector and a pair of small screwdrivers (one a philips screw driver). Charles explained that I would probably use these small screwdrivers more than any of the other tools. I also was given a small notebook and a pen. All of this went into my pocket protector. Which went into the vest pocket on my flannel shirt.
Our Pocket Protectors were freebies given to us by vendors so they would have advertisements on them like these
We went back down to the electric shop and Charles introduced me to Gene Roget again and Charles asked Gene if he would help me organize my tools and teach me some of the basics around being an electrician. Gene said that the first thing I needed to do was to lubricate my new tools. It just doesn’t do to have tools that are stiff. So, we worked on lubricating them and we even went down to the machine shop to get some abrasive paste called “jewelers rouge” that we worked into the tools to loosen them up. Gene took his side cutters and threw them up in the air and as they flew up, they rapidly opened and closed making a rattling sound. He caught them as they came down as if they were tied on his hand like a YoYo.
Wire Cutters similar to what I had
I worked the tools back and forth. Lubricating them and rubbing the abrasive paste in the joint. I had no coordination, so when I would try throwing my pliers in the air like Gene did, they would end up on the other end of the workbench, or across the room. So, I didn’t try it too often when others were around where I might injure someone. I thought. I’ll work on that more when I’m alone or just Gene is around. He had good reflexes and was able to quickly dodge my miss-thrown tools.
After Lunch Charles said that we had a job up at the coalyard that we needed to work on. He told me to grab my tool bucket and the multimeter from the cabinet. The electricians referred to it as the “Simpson”.
We had a couple of these Simpson Analog Multimeters in the shop
This was before each of us were issued our very own digital Fluke Mulimeter a few years later. I’m sure the old electricians are chuckling to remember that we used to use these old Multimeters. Charles explained to me that when you are checking voltage with the meter, that after you turn the dial to check voltage, always touch the two leads together to make sure the meter doesn’t move before touching the electric wires. This is done because if something happens that causes the meter to still be on “Resistance”, then when you check the voltage, the meter or the leads could explode possibly causing an injury. I had observed the electricians in the shop doing this back when I was a janitor, and now I knew why.
Charles explained that we needed to find out why the heater in the small pump room on the northwest corner of the dumper wasn’t running. So, we went to coalyard and found the space heater mounted along the wall. We tested it to make sure it wasn’t running. After checking the circuits with the multimeter on a panel on the wall, we found that we needed to replace a small fuse block because it had become corroded from all the coal dust and moisture.
I had seen electrical he-men go up to a panel and hold a screwdriver in their hand out at arms length and unscrew screws rapidly, one at a time. Bill Rivers had been doing that up on the precipitator roof when I was working with him while I was still on the Labor Crew. He could unscrew screws from a terminal block faster than I could unwrap Hershey Kisses.
So, when Charles told me to remove the fuse block from the panel, I thought this would be an easy task. I pulled out a screwdriver from my handy dandy tool bucket and with one hand holding the screwdriver, and the other hand steadying it by holding onto the stem of the screwdriver I moved toward the panel. Charles stopped me by saying something like: “Rule number one. Never use two hands. Especially when you are working on something hot.” Ok. I see.. If one hand is touching the metal screwdriver, and I come into contact with the screw which is electrified, then… um… yeah. Ok. I dropped one hand to my side and proceeded to remove the fuse block. That other hand remained at my side for the next 18 years when working on something hot (something is hot when it has the electricity turned on).
I explained above that I was pretty uncoordinated when it came to flipping my side cutters up into the air trying to act impressive like I knew what I was doing. Well. I couldn’t hold a screwdriver steady for the life of me. I tried to match up the head of the screwdriver with the slot in the screw, but I was pretty wobbly. It was kind of embarrassing. The truth had come out. This guy can’t even hold a screwdriver still. How is he ever going to become a real electrician?
A small fuse block like this.
Using all my concentration, I fumbled about and began working the screw out of the fuse block, when suddenly the screwdriver slipped slightly and Pow! Sparks flew. I had shorted the screwdriver between the screw and the hot post on the fuse block. There was a quick flash of light and a loud pop. Geez. The first time I’m working on something, what do I do? I blew it….. literally.
Well. Charles pointed out. The electricity is off now. Go ahead and change out the fuse block, then we will find out where the source of power is for it. So, I changed it out…. Feeling a little down that my new screwdriver now had a neat little notch on the blade where the electricity had melted off a corner of my screwdriver (I carried that notched screwdriver around for the next 10 years before I replaced it). We found the breaker that had been tripped in a DP Panel (which stands for Distribution Panel) in the Dumper Air Handler room and turned it back on. We checked the heater and it was working.
At the end of the day, when Bill Bennett came down to the shop to see how my first day went, Charles told him that I had jumped right into it and already had a notch in my screwdriver to prove it. Both Bill and Charles were good-natured about it. I filled out my timecard which told a short story about my first adventure as an electrician.
As I walked to the parking lot with Bill Rivers to go home, I was thinking that even though I had been full of nerves all day, this had to be one of the most exciting days of my life. I was actually one of the electricians now. I had the feeling that somehow something was going to happen and they were going to tell me that they made a mistake and that I would have to go back to the labor crew. That was a feeling that haunted me for about 3 months after moving to the electric shop.

Your memory still amazes me. It’s like you kept a copy of every day’s time card. I’ll bet your time cards take up a whole room at Sooner!Great article. I still have some of the tools I was given on my first day in the Results Dept. at the Horseshoe Lake Plant in June, 1970 (don’t tell the Evil Plant Manager).

Power Plant Manhole Mania
Originally posted February 1, 2013:
It is vitally important that a manhole cover be round. By just being square or even oval, it could mean death to some unsuspecting electrician. You see, only a perfectly round manhole cover will never be able to fall down into a manhole. No matter how hard you try, you just can’t fit a bigger circle through a smaller circle. An oval or square cover could fall through the hole when turned just right but not a round one. A typical cast iron manhole can weigh up to 500 pounds.
Here is a manhole cover turned upside down. Because of the way it is shaped, when you push the cover over the hole, it falls right into place.
Not long after becoming an electrician, and shortly after the Rivers and the Rose story that I mentioned last week (see the Post “Rivers and Rose in the Power Plant Palace“), we had a cable really go to ground between the main plant and the coalyard. The cable that went to ground was called a 500 MCM cable. What this means is that 500,000 circles of 1 mil (or one milli-inch) in diameter can be put in a circle that is 500 MCM in diameter. A typical 500 MCM cable is good for a 400 amp load at 6900 volts.
500 MCM cable. Over 2 inches in diameter.
For large industrial circuits, 3 phases of electricity are used instead of just one like you have in your house. With three phases of electricity, you have a constant amount of power being applied to the entire circuit at all times. With a one phase circuit, you have zero power 120 times every second. So with any “decent” power circuit, you have 3 phases of electricity.
When you add up the difference betweenvoltages of all three phases at one time, you always equal zero because you have the same amount of positive volts with negative volts at any given time. So, you will find that you always have a constant voltage between all three phases at any time.
The cable that went to ground was the coalyard station power cable. Not only were there three phases of power, but for each phase there were two 500 MCM cables. That means that this circuit was good for 800 amps of power at 6,900 volts. Giving you a capacity of 5.5 Megawatts (or 5 million, 500 thousand watts) of power. These cables were so big that a typical industrial Wire cable chart doesn’t even go this high:
500 MCM cable is also known as 5/0 cable (pronounced 5 aught). The 445 amps for the 4/0 cable are for only 50 volts. We had 6900 volts.
In a Coal-fired power plant, you have a redundant system for everything. So, the coalyard wasn’t completely in the dark. It had just swapped over to the redundant circuit. — This always amused me. In my English and Poetry classes in College I would have points taken off for being “redundant”, but in the power plant this was necessary to keep the plant running at all times.
As I said many times 15 years later, when I was training operators and electricians to be certified substation switchmen, “I know this is boring, but you have to learn it…” (but that is another story).
So, to make a rather boring lecture shorter, I will skip the part about how we had a hypot from the T&D (Transmission and Distribution) department brought in so big that it had to come in a van. They attached it to the cables to find where the short to ground was located. I’ll skip the part about how it was decided to replace the faulty cables going to the coalyard 1/2 mile away. I’ll also skip the part about how Charles Foster was able to finagle the use of Stanley Elmore’s precious blue Mitsubishi mini-tractor to try to pull the cables from one manhole to the next (the first time anyone outside the garage was able to operate his most beloved tractor…..).
A tractor just like this
Oh, and I’ll skip the part about how 1000 feet of this cable cost about $10,000 and we had six cable to replace for a cost of about $320,000 just for the cable… I’ll also skip the part about how this little tractor was too small to pull the cables through the manholes from manhole to manhole up to the coalyard, so we sent in for the big guns from the T&D department to use their equipment that pulled the cables through the manholes as easy as pulling the wool over Gene Day’s eyes while playing a joke on him. (Don’t get me wrong…. I know in his heart, Gene Day really appreciated a good joke. Gene Day is one of the best men I have ever been able to call “Friend” — which I would do shortly after playing a joke on him, after I returned to consciousness).
Anyway, after this episode was all over it was decided that something needed to be done about how all the manholes from the plant to the coalyard were always full of water. You see, the manholes were easily deeper than the lake level so water naturally leaked into them. Each of them had a pump in them that was supposed to keep them dry, but somewhere along the line, in the 5 years the plant had been in operation, each manhole pump had failed at one time or other… When pumping out the first manhole, it took days, because as you pumped out that first manhole, water would run from one manhole to the other as you actually ended up pumping out all the manholes down to the point where the cables went from one manhole to the other.
So, none other than the “newbie” was appointed as the keeper of the Manhole pumps. Yep. That would be me. So, for the next few months I spent almost all my times pumping out manholes and repairing all the pumps that had been submerged in water for years. This was my first real job.
This was my real introduction to becoming a real plant electrician (You can see how I really like using the word “real”). The most common job of an electrician was to take a motor that had failed or was scheduled to be overhauled and repair it and put it back in place to continue on it’s “tour of duty”. It’s amazing how you can take a motor that has failed, and you can “rebuild” it and put it back in operation. — This has come in handy at home as the cooling fan motor on the air conditioner unit on your house goes out every few years. I have yet to call an air conditioner man to my current house where I have lived for 11 1/2 years (now 18 years).
I remember that Charles Foster had told me that “paperwork” was very important when it came to motors. A history had to be kept. Certain steps had to be performed before, during and after repairing a motor. It had to be meggared properly (see the post from last week to learn more about meggars: Rivers and a Rose of the Power Plant Palace).
So, I asked Ben Davis if he could show me what I needed to do to fix a motor. His immediate indignant response was, “What? You don’t know how to fix a motor?” My response was, “No, I don’t know. Would you show me?” Ben, who up to that point had presented himself with displeasure at my presence in the shop, suddenly smiled and said, “Sure! Let me show you what you need to do!”
Ben showed me all the steps you go through to repair and “document” a motor repair in great detail. I was glad that I had found that Ben was just putting on a front of disgust at my presence in the Electric shop only to show me at the “proper” time that I had been “misjudging” him as being a grumpy person when he wasn’t really. There is a certain art to this which I describe in detail in this post: “Power Plant Art of Making a Bad First Impression“.
I had figured, before this time, that Ben really had a kind heart because I figured that if Diane Lucas and Andy Tubbs, who I both admired greatly considered Ben as a good friend, then he must really be a good guy underneath, even though he was keeping this hidden from me.
I knew the moment he smiled at my response when I told him I really didn’t know anything, that Ben had a kind heart. He couldn’t hide it any longer. If I had asked the same thing to OD McGaha, one of the other B Foremen in the shop, for instance, he would have told me to go to hell. But not Ben.
I have more to tell you about Ben, but I’ll save that for a later post. For now, I’ll just say that though Ben may not have known it during the time I spent as an electrician, he has always been close to my heart. I have always had Ben and his family in my daily prayers from the day that he smiled at me and explained to me how to repair a motor.
So, how does a lone newbie electrician pull a 500 pound lid off of a manhole by himself? Well. He uses a Manhole cover puller of course.
A Manhole cover puller
Ok. Our manhole cover puller wasn’t blue like this, but it had a similar shape. With a simple tool like this a 500 pound manhole cover could be popped out of the hole and dragged away. So, I used this tool as my one man crew (myself) went from manhole to manhole, where I pumped each out and lowered a ladder into each hole and disconnecting the drenched motor and brought it back to the shop where I dried it out (using the hot box in the shop that doubled as a heater for lunches), and repaired it and re-installed it.
We had all the manholes in the plant identified. I painted the numbers on each lid with orange paint. It was while I was working in the manholes 15 feet below ground that I appreciated the round manhole. I knew that as long as that manhole cover was round, it couldn’t accidentally be knocked into the hole only to crush me to death below.
Other things were of concern in the manholes where I worked… For instance, many of these holes had been underwater for at least a couple of years, and the entire manhole was covered with a kind of slime. there were also high voltage cables that had splices in some of the manholes, and I remember Gene Roget telling me that he had seen sparks flying off of some of them when they were hypoting the cables looking for the ground. The dank smell of the manholes made you think that there were probably some kind of “swamp gases” in there.
Nevertheless, when I grew weary of dragging the heavy shellacked wooden ladder from hole to hole, I devised a way to climb down into the manholes using the drain pipe from the motor. This was before OSHA had implemented all the confined spaces rules in 1994 that would have prevented me from entering a manhole alone. I was improvising and taking a risk of falling and hurting myself each time I entered a manhole.
I ran into one of the reasons for not leaving a person in a manhole alone one time when I was working in a manhole near the intake house and another crew drove up and parked their truck near the hole I was working in. I remember that while I was working there, I suddenly became nauseous. Not sure why, I climbed out of the hole.
The truck that had been left idling nearby had been emitting toxic fumes that had looked for the lowest place they could settle, and that happened to be in the manhole where I was working. After that, I always kept an ear out for any motor vehicles nearby when I was in a manhole.
Ten years later, in 1994, OHSA added some new laws to the books that made it mandatory to have a “hole watch” stand outside a hole watching you while you worked in a manhole. You even had to have a safety harness tied to a safety hoist so that if you passed out while in a manhole the hole watch could pull you out without having to enter the hole.
This is a special hoist designed to lift a person out of a confined space without seriously injuring someone that is caught on obstacles.
Needless to say. I got my feet wet as an electrician popping in and out of manholes like the gopher in the arcade that you try to bop on the head.
One interesting story that happened during this time happened when Blake Tucker, who had been a summer help with me in the garage, and then later became a summer help in the electric shop, was sitting with me while we were going to fix a pump in manhole 215 (I believe this is the number of the manhole next to the intake where the fly ash pipes go over the intake).
The hole was full of water, and the pump had naturally tripped the breaker….. For some reason I decided to go into the intake switchgear and reset the 120 volt breaker to the pump in the Distribution Panel. When I did. I returned to the hole where Blake was waiting for me. I reached down into the hole with my foot and I kicked the drain pipe that rose from the pump and made a 90 degree turn up close to the entrance.
When I kicked the pipe, the motor actually began running. We could see it 15 feet below us in the clear water running. It was an open face motor, meaning that it wasn’t sealed and made to be a submersible pump, yet it was running under water. A year later we decided that it made more sense to replace all the open motors with submersible pumps.

A submersible pump designed to run underwater
Blake Tucker and I watched for 1/2 hour as the pump sucked out the water from the manhole. When the level of the water reached the top of the motor, the outboard fan that had been slowly rotating all of the sudden kicked into high gear and we could see that the pump had been running at full speed all along.
This fascinated me. I figured the water must have been pure enough not to be too conductive (pure water is a natural insulator…. oddly enough). We could easily see this pump through 15 feet of water, so it must have been pretty clean. That was the only time I have ever seen an open motor happily running submersed in water… It is not something you see every day….. for instance…. It is not every day that you see a janitor with a Psychology major acting like an electrician sitting beside a manhole staring down into the darkness in a power plant either. But there you are…
Making Power Plant Friends with Motor Alignment
I know I’m getting old when I pick up a small piece of paper and I am suddenly taken back 17 years to the day I pulled the small page from the Hunzicker Brothers Inc. Notepad sitting on the desk in the Electric Shop office. It was the day that I was finally able to come to the aid of a noble Power Plant Man that the plant generally referred to as “Stick”.
Gary (Stick) McCain
Gary McCain, or Stick, is a tall thin Power Plant Man (sort of like a stick) known for his intellect and knowledge of “Machine Language”. In this case, “Machine Language” refers to the ability to understand how machines work, not how to talk directly to computers using zeroes and ones.
Gary had just walked into the Electric Shop office at the power plant in North Central Oklahoma as lunch was ending. He was carrying a textbook, which seemed odd right off the bat. He explained that some of the machinists and mechanics had been sent to motor alignment school and they had been given this textbook in case they wanted to refer back to the material that was covered in the class.
Gary sat down next to me and set the book on the desk opening it to the page he had bookmarked (Yeah. We used to use books made out of paper, and we put pieces of paper between pages to bookmark the pages we wanted to remember… Bookmarking wasn’t something new with Internet browsers).
Gary (am I going to start all my paragraphs with the word “Gary”? Maybe the next paragraph, I’ll just say “That tall guy”) pointed to a formula on the page and asked me if it was possible to use the computer to make calculations that will help him align motors using this formula.
I told that tall guy (Gary) that we could use a program called “Excel” (from Microsoft) that could be used to solve problems just like that. So, I grabbed the small sheet of paper off of the Hunzicker Brothers Inc. notepad and wrote down the variables for the formula on one side, and the four formulas on the back side. Here is what I wrote:
Variables for the Motor Alignment formulas
Oh yeah. I think I ripped off the corner of the paper to use as a bookmark because I didn’t like the one Gary was using. It was too small.
Motor Alignment Formulas (or is it Formulae?)
I guess at this point I should stop and tell you what is meant by “motor alignment” and why machinists and mechanics are interested in this in the first place.
The alignment that is done with a motor is performed when you are putting a pump back in place or some other equipment like a gear box or fan shaft or… well… a lot of things. You have to make sure that the shaft on the motor is perfectly aligned with the pump otherwise it will quickly tear something up when you turn it on.
motor coupled to a compressor
This picture shows how the motor is aligned up with the compressor so that the red coupling lines up perfectly. Once it is aligned the coupling can be bolted together to connect the motor to the pump.
Notice that the motor has bolts to mount it to the skid in the front and the back on both sides, as well as the pump. These are called “Feet”. Usually when you put the pump and the motor back in place, they don’t line up perfectly, so thin pieces of brass called “shims” are used to raise the various feet just the right amount so that the shaft on the motor and shaft on the pump are looking right at each other.
A special piece of equipment is used to check the alignment. It is called a “Dial Caliper” and it is mounted to the coupling on the motor and the pump with a magnet and it tests the alignment as it is rotated around.
A mounted dial caliper used to measure the alignment of the motor
I’m sorry if I’m boring those of you who don’t immediately see the beauty of Motor Alignment. Try pretending that the dial caliper is something invented by ancient aliens if you need to make this part of the post more interesting (actually, who needs ancient aliens when you have machinists?).
Gary told me that the company was looking into buying laser guided motor alignment machines for only $30,000 a piece. They would probably buy three of them that could be used between the four main plants. He said that he didn’t think we needed them if we could use these formulas to calculate exactly how to align the motors. This would save the company around $90,000 and at the same time show the mechanics the “joy of math”!
So, I made some notes on another page which simplified, (or maybe complicated) the formulas further. Then I sat down at the computer and began putting them into Excel. The idea was to have the person doing the motor alignment take some notes, then go to the computer and enter them into the Excel sheet and it would tell them right away how many shims to put under any of the 8 feet (four on the motor and four on the pump).
Here are the notes I made:
Notes made to calculate the motor alignment
If you are Jesse Cheng (or some other old time calculator geek), you can see what I was doing with my notes. I was thinking of the next steps… which I’ll explain below…. (oh… ok… I’ll tell you… this is the code that you would use if you were creating a program for a Casio calculator).
After creating the spreadsheet, Gary headed out the door to go start aligning a motor using our newfangled motor alignment method. A little while later he came back into the shop and pulling out his handy dandy notepad he read off the notes he had taken while he put the values into Excel… When he was finished, he wrote down the results and headed back out the door to add the proper shims to the motor and the pump.
Handy Dandy Power Plant Notepad
We had to tweak the program a little to work out the bugs, but after a couple of tries it worked very well and Gary was pleased. Only, there was one problem with this method… Over the next couple of weeks, Gary would come bursting into the electric shop office interrupting me and Charles Foster while we were having a deep discussion about the virtues of banana peppers on ham sandwiches.
Charles Foster
So, I suggested to Gary that we could use a calculator to do the same thing that we were doing with the spreadsheet. That way he wouldn’t have to travel back and forth to the computer. Instead, he could just stand there at the motor and enter the information and have it display the answers that he was seeking.
Right off the bat (hmm… the second time I have used that “cliche”…. I need to read more often), Gary didn’t understand how a calculator could do this. So, I explained to him that some calculators are programmable and I can write a program on the calculator that would do just that. I said, “Let me show you”….. After all, I had grown up in Missouri (the Show Me State)… So, I took my calculator off of the top of the filing cabinet and placed it on the table.
My Sharp Calculator with the Thermal printer connecting to a tape recorder
I used the thermal printer to connect the calculator to the tape recorder to store my programs, so I didn’t have to enter them manually after I entered them once.
I took my notes and wrote the following program and entered it into the calculator.
The short quick version of the calculator program
I gave the calculator to Gary and showed him how to run the program and sent him to try it out for himself. He was very excited about this and offered some suggestions to make the program easier to use.
A few days later Gary caught me walking across the maintenance shop and showed me a catalog with various calculators for sale. He said he wanted to buy some calculators for the shop so that every person that had been trained to align motors had a calculator with a program on it. I showed him a Casio calculator that would work for about $70. So, he ordered a better one.
Gary ordered the Casio CFX-9850G
Even though the language for programming it was different than the Sharp calculator, it didn’t take long for me to write a program for it that did the same thing since I had sort of already written it by that time. After Gary proved to his foreman that the calculator worked, he ordered several more and when they arrived he asked me if I could program them as well.
It took almost a half hour just to type the program into each calculator, so I bought a small pigtail that connected two calculators together. This allowed me to copy the program from one calculator to another one. So, when Gary arrived one day with a box of over 20 calculators for the rest of the plants, it took me longer to open the packages than it did to copy the program from one calculator to the next.
The pigtail I used to connect the calculators
Since the calculator was a graphic calculator, I thought about improving the program by drawing a little picture of a motor shaft and a pump shaft and showing how they were out of alignment after the information was entered, but I never took the time to do that as I was on to another computer project by that time (which I will write about later).
So, think about this. The company was willing to buy $90,000 worth of laser-guided motor alignment equipment to do something that machinists and mechanics already knew how to do. The specialized equipment would work, and it might have been faster I suppose. With the aid of a programmable calculator, however, a mechanic can stand at the motor, takes a few measurements and come up with the same results probably just as fast as the laser-guided motor alignment gizmo could do it.
Either way, the mechanic still had to install the same number of shims under the same feet whether they used the calculator and the dial caliper or the laser beam. The 26 or so calculators that were purchased for the four plants came up to less than $2,000, which is a savings of $88,000. I don’t think the laser would have saved that much time. It still had to be carried over to the motor and plugged in and mounted on the motor. My guess is that as soon as the laser was dropped on the floor accidentally, it would have been broken anyway.
The best part of this little project was that I was able to help out a True Power Plant Man Gary McCain, that I hadn’t really had the opportunity to help much before. Gary didn’t need much help as he is one of those Power Plant Men that people seek out when they need advice. So, when he came to me and asked for help with the computer, I was more than glad to do what I could to help him.
Sometimes it is a little difficult for my wife to understand why I keep scraps of paper laying around that have meaningless scribbles on them. One might be a doodle that some friend of mine created one day while talking on the phone. Another might be a fortune from a cookie that I opened when I was eating lunch with a coworker. Today the piece of paper I picked up happened to have a mathematical formula written on the back.
I think my son understands now that when I seem to be picking up trash off of the table and a tear comes to my eye, it isn’t because I have just picked up something rotten, but because I have just been transported back in time to place where I am with some people that I love. It doesn’t stop him from saying, “Dad? It’s just a piece of paper. Geez!” Well… I know I’m getting old… but that scrap of paper is poetry to me.

It is important to think outside the box to break new ground as long as you bring common sense along for the ride. It seemed that during the days when I was a summer help, and even when I was a laborer on Labor Crew that in order to be promoted you had to come up with one grand idea that set you apart from the others and that also failed miserably.
It was said that the electrical supervisor there before Leroy Godfrey (I can see his face, but his name escapes me), was promoted to that position after he caused the destruction of one of the Intake pump motors (a very large pump that can pump 189,000 gallons of water per minute).
To name a couple of minor “Faux Pas” (how do you pluralize that word? I don’t know), let me start out with the least embarrassing and less dangerous and work my way to the most embarrassing and most dangerous of three different stories of someone thinking out of the box while leaving common sense somewhere behind and maybe wishing they could take back that day.
The first two stories both involve the Electrical Supervisors of two different Power Plants.
Tom Gibson, the Electrical Supervisor from our plant was trying to find a way to keep moisture out of the Bottom Ash Overflow Sump Pumps. This was a reoccurring problem that required a lot of man hours to repair. The bell shaped pump would have to be pulled, the motor would have to be disassembled and dried, and new seals would have to be put in the pump to keep it from leaking.
A Bottom Ash Overflow Sump Pump or BAOSP for Short
So, Tom Gibson decided that he was going to fill the motor and pump cavity with turbine oil. All electricians knew that oil used in turbines is an insulator so electrically it wouldn’t short anything out. But something in the back of your mind automatically says that this isn’t going to work. I remember helping to fill the motor up with oil in the Maintenance shop and hooking up some motor leads from the nearby Maintenance shop 480 volt switchgear. Needless to say, as soon as the pump was turned on, it tripped the breaker and oil began leaking from the cable grommet.
That’s when common sense tells you that the all the oil causes too much drag on the rotor which will cause a 480 motor to trip very quickly. After removing some of the oil and trying it again with a larger breaker and still having the same result Tom was satisfied that this just wasn’t going to work. The pump and motor was sent away to a nearby electric shop to be rewound and other ways were developed by the help of our top notch machinist genius Randy Dailey who came up with a positive air pressure way to keep water out of the Bottom Ash Overflow Sump Pump and motor (also known as the BAOSP). Not much harm done and Tom Gibson didn’t feel too bad for trying something that the rest of us sort of thought was mildly insane.
The next story was told to me by my dear friend Bob Kennedy when I was working at a Gas Powered Plant in Midwest City and he was my acting foreman. So I didn’t witness this myself. This one was a little more dangerous, but still thankfully, no one was hurt. Ellis Rooks, the Electrical Supervisor needed to bump test a 4200 Volt motor and wanted to do it in place. For some reason he was not able to use the existing cables, maybe because that was the reason the motor was offline. Because one of the cables had gone to ground.
So, he decided that since the motor only pulled 5 to 10 amps he could use #10 wire and string three of them (for the three phases of the motor) from the main High Voltage switchgear across the turbine room floor over to the motor. Now, most electricians know how many amps different size wires can generally handle. It goes like this: #14 – 15 amps, #12 – 20 amps, #10 – 30 amps, #8 – 50 amps and on down (smaller numbers mean bigger wires).
So, Ellis thought that since the motor only pulls around 5 amps, and he only wanted to bump the motor (that is, turn it on and off quickly) to watch it rotate, he thought that even though there was normally three 3 – 0 cables (pronounced three aught for 3 zeroes, very large wire) wired to the motor, this would be all right because he was only going to bump it.
This works when you are using is 120 or 220 volts
Needless to say, but I will anyway, when the motor was bumped, all that was left of the #10 wires were three black streaks of carbon across the turbine room floor where the wire used to exist before it immediately vaporized. You see, common sense tells you that 4200 volts times 5 amps = 21,000 watts of power. However, the starting amps on a motor like this may be around 50 to 100 amps, which would equal 210 to 420 Kilowatts of power (or about 1/5 to 2/5 of a Megawatt). Thus vaporizing the small size 10 wire that is used to wire your house.
All right. I have given you two relatively harmless stories and now the one about cracking the boiled egg in the boiler. This happened when I was still a janitor but was loaned to the Labor Crew during outages. When the boiler would come offline for an outage, the labor crew would go in the boiler and knock down clinkers and shake tubes to clean out clinkers that had built up around the boiler tubes in the intermediate pressure area of the boiler.
Clinkers are a hard buildup of ash that can become like large rocks, and when they fall and hit you on the head, depending on the size, can knock you to the floor, which makes wearing your hardhat a must. Your hardhat doesn’t help much when the clinkers falling from some 30 feet above hits you on your shoulder, so I always tried to suck my shoulders up under my hardhat (like a turtle pulling in his arms and legs) so that only my arms were left unprotected.
It wasn’t easy looking like a pole with no shoulders, but I tried my best. I think Fred Crocker the tallest and thinnest person on Labor Crew was the best at this. This is the Reheater area of the boiler in the diagram below:
Diagram of a boiler
Before we could get into the boiler to start shaking tubes, the dynamiters would go in there first and blow up the bigger clinkers. So, for a couple of days some times, at the beginning of an overhaul, you would hear someone come over the PA system about every 20 minutes saying, “Stand Clear of Number One Boiler, We’re Gonna Blast!!!” This became so common to hear over the years that unless you were up on the boiler helping out, you didn’t pay any attention to it.
This is something that is only done at a Coal-fired Power Plant because Gas Plants don’t create Ash that turns into Clinkers. Maybe some Soot, I don’t know, but not Ash. Which brings to mind a minor joke we played on Reginald Deloney one day when he came from a gas plant to work on overhaul. Reggie automatically reminded you of Richard Pryor. He had even developed a “Richard Pryor” way of talking.
Richard Pryor trying to look like Reggie Deloney
We were going to work on a Bowl Mill motor first thing, which is down next to the boiler structure in an enclosed area. We brought our large toolbox and other equipment over to the motor. Andy Tubbs and Diana Brien were there with Reggie and I. I think Gary Wehunt was there with us also.
When someone came over the PA system saying, “Stand Clear of Number Two Boiler, We’re Gonna Blast”, all of us dropped everything and ran for the door as if it was an emergency. Reggie, not knowing what was going on ran like the dickens to get out in time only to find us outside laughing at the surprised look on his face.
Like this
Anyway. That wasn’t the day that someone wished they could take back, but I thought I would throw that one in anyway so that now Reggie will wish that he could take back that day.
When I was on Labor Crew, and we were waiting on the boiler for the dynamiters to blast all the large clinkers, the engineer in charge, Ed Hutchins decided that things would go a lot quicker if all the laborers would go into the boiler and shake tubes while the dynamiters were setting their charges. Then we would climb out when they were ready to blast, and then go back in. So, we did that. All 10 or so of us climbed into the boiler, and went to work rattling boiler tubes until we heard someone yell, “Fire In The Hole!!!” Then we would all head for the one entrance and climb out and wait for the blast.
The extra time it took to get all of us in the boiler and back out again actually slowed everything down. We weren’t able to get much work done each time, and everyone spent most of their time climbing in and out instead of working, including the dynamiters. So Ed had another brilliant idea. What if we stayed in the boiler while the dynamite exploded? Then we wouldn’t be wasting valuable time climbing in and out and really wouldn’t have to stop working at all.
Of course, common sense was telling us that we didn’t want to be in an enclosed boiler while several sticks worth of dynamite all exploded nearby, so the engineer decided to prove to us how safe it was by standing just inside the entrance of the boiler with his ear plugs in his ears while the dynamite exploded. The dynamiters at first refused to set off the charges, but after Ed and the labor crew convinced them (some members on the labor crew were anxious for Ed to try out his “brilliant idea) that there really wouldn’t be much lost if the worst happened, they went ahead and set off the dynamite.
Needless to say…. Ed came wobbling his way out of the boiler like a cracked boiled egg and said in a shaky voice, “I don’t think that would be such a good idea.” All of us on the Labor Crew said to each other, “..As if we needed him to tell us that.” I think that may be a day that Ed Hutchins would like to take back. The day he learned the real meaning of “Concussion”. I think he was promoted shortly after that and went to work in Oklahoma City at Corporate Headquarters.

When you have pallets double-stacked, you should only move them about with a pallet jack. The bottom pallet – and whatever is stacked on it – is thoroughly supported. And even if the pallet jack is powered, you aren’t likely to get in trouble with rapid acceleration.
As you would with a fork lift truck.
And the double stacked pallets are truck mirrors boxed for shipment to retailers. A couple hundred mirrors. And I dumped both pallets when I went to back up and turn into the warehouse aisle.

Modern parables like these are much too good to waste! They should be included in every freshman Congressman’s Washington Welcome Kit when he first takes office and new ‘reminder’ versions again every time he wins an election. These are wonderful essays on unintended consequences, at which our Congress is among the best!

I worked with Ed on the Precipitator control replacement project (84 controls X 2) in 2006 I think. He was getting ready to retire at the time. He was a good engineer and a tough customer. I was working for the control supplier and those 168 controls were the first installation of a brand new control design. I had lead the design team for the controls and this was the culmination of our work. I spend more days and nights than I can remember going up and down the aisles of controls loading software fixes into the processors! Anyway, great people at the plant and great memories… including a rapper control cabinet that took the express route to the ground elevation from the precip roof! (ouch, it really is the sudden stop that gets you!)

Thanks for the comment John! It’s good to hear about improvements to the Precipitator and the control rooms I used to call home. I spend many weekends walking back and forth through those control rooms.

OMG – The very thought of a group staying in the boiler when the dynamite went off! Thank goodness THAT didn’t happen. I felt the tension just reading that bit. I’m glad Ed came out of it all right.

A Power Plant Doctor Does a Jig in a Puddle of Acid
Originally Posted May 18, 2012
George Pepple was the chemist at the plant when I first arrived in 1979. His last name is pronounced “Pep-Lee”. A chemist plays an important role in a power plant. The plant treats their own water and has it’s own sewage system. The chemist spends their time with these activities.
They do other things like check ground water for contaminates, and lake water for bacteria, and a host of other things. Hydrochloric Acid is used to balance the PH of the water. As far as I know, George Pepple was the only one at the plant with a PhD, which gave him the title of Doctor. No one called him Dr. Pepple (which sounds like a soda pop). We either called him George or Pepple (Pep Lee) or both. He had a sort of Einsteinian simplicity about him. To me he was the perfect combination of Einstein and Mr. Rogers from “Mr. Roger’s Neighborhood”:
Albert Einstein
Mister Rogers
One other thing I would like to add about George was that he developed a special process for Cupric chloride leaching of copper sulfides. This was a patented process (1982) which is now owned by the Phelps Dodge Corporation which is a copper and gold mining company. As humble as George Pepple was, he never mentioned this to anyone at the plant as far as I know.
When he would page someone on the PA system (gray phones), he would always do it in a straight monotone voice. putting no accents on any of the words and he would always repeat his page twice. Like this: “PaulMullonLineOne. PaulMullonLineOne.”
Gaitronics Gray Phone
Before I get to the point where George is dancing in the acid, I first need to tell you about Gary Michelson, since he had a role to play in this jig. In an earlier post: In Memory of Sonny Karcher, A True Power Plant Man, I remarked that Sonny Karcher had told people when he introduced me to them that I was going to college to learn to be a writer (which wasn’t exactly true. The writing part I mean…. I was going to college… and.. well… I am writing now), and that I was going to write about them. In doing so, some people took me in their confidence and laid before me their philosophy of life.
Jerry Mitchell being one of them (as you can read in an earlier post about “A Power Plant Man Becomes an Unlikely Saint“). Jerry had filled me with his own sense of humility, where it was important to build true friendships and be a good and moral person. His philosophy was one of kindness to your fellow man no matter what his station in life. If there was someone you couldn’t trust, then stay clear of them.
Gary Michelson was another person that wished to bestow upon me his own personal wisdom. We worked for about 3 days filtering the hydraulic oil in the dumper car clamps and in the coal yard garage. While there, he explained to me why it was important to be the best in what you do. If you are not number one, then you are nobody. No one remembers who came in second.
He viewed his job performance and his station in life as a competition. It was him against everyone else. He didn’t care if he didn’t get along with the rest of the people in the shop (which he didn’t) because it is expected that other people would be jealous or resentful because he was superior to them.
According to Gary his family owned part of a uranium mine somewhere in Wyoming or Montana. He thought he might go work for his father there, because truly, he was not a True Power Plant Man. He reminded me slightly of Dinty Moore. Like a lumber Jack.
Dinty Moore
As I mentioned in the post about the “Power Plant Genius of Larry Riley“, Gary Michelson had the title “Millwright”. Which no one else in the shop seemed to have. He had been certified or something as a Millwright. Gary explained to me that a Millwright can do all the different types of jobs. Machinist, Mechanic, Pipe fitter, etc.
I remember him spending an entire week at a band saw cutting out wedges at different angles from a block of metal to put in his toolbox. Most mechanics at this time hadn’t been issued a toolbox unless they had brought one with them from the plant where they had transferred. Gary explained to me that his “superiority was his greatest advantage.” Those aren’t his words but it was basically what he was saying. That phrase came from my son who said that one day when he was imitating the voice of a video game villain named Xemnas.
Filtering the hydraulic oil through the blotter press was very slow until we removed most of the filters.
An Oil Blotter Press Similar to the one we had, but our press did not have “NAKIN” written on it.
It was a job that didn’t require a lot of attention and after a while became boring. That gave me more time to learn about Gary. He filled the time with stories about his past and his family. Since I hadn’t met Ramblin’ Ann at this point (See the post “Ed Shiever Trapped in a Confined Space with a Disciple of Ramblin’ Ann“), I was not able to contribute my share. In the middle of this job we were called away to work on a job in water treatment where a small pump needed to be re-installed.
During this time at the plant every pump, fan, mill and turbine were brought to the maintenance shop and disassembled, measured, cleaned, honed and reassembled before the plant was brought online for the first time. This is called doing a “check out” of the unit. The electricians would check every motor, every cable and every relay. The Results team (Instrument and Controls as they were later called) would check out the instrument air, the pneumatic valves and the control logic throughout the plant.
Gary had me go to the tool room and get some rubber boots and a rain suit. When we arrived at the water treatment building George Pepple was there waiting for us. The pump was in place and only the couplings needed to be connected to the acid line. Gary explained to me as he carefully tightened the bolts around the flange that you had to do it just right in order for the flange to seat properly and create a good seal. He would tighten one bolt, then the bolt opposite it until he worked his way around the flange. He also explained that you didn’t want to over-tighten it.
Pipe Flange
Anyway. When he was through tightening the couplings I was given a water hose to hold in case some acid were to spray out of the connections when the pump was turned on. After the clearance was returned and the operator had closed the breaker, George turned the pump on. When he did the coupling that Gary had so carefully tightened to just the right torque using just the right technique sprayed a clear liquid all over George Pepple’s shoes.
Gary quickly reached for the controls to turn off the pump. I immediately directed the water from the hose on George’s shoes while he began to jump up and down. In last week’s post I explained that when I was working in the River Pump forebay pit shoveling sand, there was a point when I realized that I was covered from head to foot with tiny crawling bugs, and I felt like running around in circles screaming like a little girl (See “Power Plant Men Taking the Temperature Down By The River“).
If I had done that, I probably would have been singing the same song and dance that George Pepple was doing at that moment. Because he indeed was screaming like a little girl (I thought). His reaction surprised me because I didn’t see the tell tale signs of sizzling bubbles and smoke that you would see in a movie when someone throws acid on someone. I continued hosing him down and after a minute or so, he calmed down to the point where he was coherent again. He had me run water on his shoes for a long time before he took them off and put on rubber boots.
After hosing off the pipes, Gary took the coupling apart and put the o-ring in place that he had left out.
Rubber O-Ring
I made a mental note to myself. — Always remember the o-ring.
Besides those two jobs, I never worked with Gary Michelson again. When I returned the next summer Gary was no where to be found. When I asked Larry Riley about it, he just said that they had run him off. Which is a way of saying… “He ain’t no Power Plant Man.” George Pepple on the other hand was there throughout my career at the power plant. He was a True Power Plant Man, PhD! When George was around you knew it was always “A wonderful Day in the Neighborhood”. When I would hear George Pepple paging someone on the Gray Phone (the PA system) in his own peculiar way, I would think to myself… “I like the way you say that.” (As Mr. Rogers used to say). I will leave you with that thought.

Funny isn’t it, how the ones that are the best (in their own minds) do stupid stuff like forgetting the O-ring. Apparently they can’t see for all the jaw-flapping involved in patting themselves on the back. Not that I haven’t had a few days I’d rather not talk about too.

New Home in the Power Plant Electric Shop
Originally Posted January 4, 2013:
November 7, 1983 I walked into the electric shop from the Power Plant Parking Lot with Bill Rivers. Bill was an electrician that I had been carpooling with off and on for almost a year. I remember walking in the door and the first thing I noticed were two guys leaning against the counter by the coffee pot that I hadn’t seen before. They looked like a couple of Electrical Contract hands.
When I came in the door, Bill told them that I was the new electrician. They both looked very surprised. The tall one told me that his name was Art Hammond and that this was his first day as an electrician in the shop also. He had just been hired. The shorter guy introduced himself as Gene Roget (it is a French name pronounced “Row jay” with a soft J). I could tell by his shock and look of disappointment at my young appearance and obvious lack of experience that he had been expecting to be hired permanently along with Arthur.
My new foreman was Charles Foster, the person that had asked me to think about becoming an electrician in the first place. Charles was a calm mild mannered person that made it clear to me the first day that I could call him Charles, or Foster or even Chuck, but don’t call him Charlie. Ok. I made a note of that in my mind….. When the need arises to really irritate Charles, I should remember to call him Charlie. — Just a side note… That need never did arise. I did think it was funny that I had referred to my previous foreman Larry Riley as my Foster Father, and now I actually had a Foster for a Foreman. The electric shop had a short Monday Morning Safety Meeting and then I officially began my 18 year career as an electrician.
I could go on and on about how Charles Foster and I became the best of friends. I could fill up post after post of the things we did and the hundreds of conversations we had each day at lunch…. and um…. I suppose I will in good time. Today I just want to focus on what we did the first day. The first thing Charles told me after making it clear that “Charlie” was not the way to address him, was to tell me that he believed that the way I would become a good electrician was for him to not tell me much about how he would do something, but instead, he would let me figure it out myself. And if I made a mistake. That was all right. I would learn from it.
I really hated making mistakes, and I wished at the time that he would let me follow him around telling me his electrical wisdom. Finally, in my mind I thought, “Ok. If Charles didn’t mind my making mistakes, then I will try not to mind it either.” It was hard at first, but eventually, I found that making mistakes was the highlight of my day sometimes… Sometimes not… I’m sure I will talk a lot about those in the coming months.
I followed Charles up to Bill Bennett’s office. He was our A foreman, and there was a cabinet in his office where he kept all the new electrician tools. I was given a used black five gallon bucket and a tool pouch to carry my tools. Like my first day as a summer help, I had to learn the name of a lot of new tools that day. There were crimpers, side cutters, Lineman’s Pliers, strippers and Holding Screwdrivers. I was given a special electrician pocket knife and was told that I would have to keep it very sharp. I had all sizes of screwdrivers and nut drivers. I put all the tools including the tool pouch into the black plastic bucket.
A black tool bucket like this
Bill Bennett was a tall very thin black man. He was a heavy smoker. This showed on his face as he looked older than I thought he really was. He spoke with a gruff voice from years of smoking. He was a very likable person (like most Power Plant Men). He told me that they had tried really hard to get me in the electric shop because the two men in the corner offices really didn’t want me to move off of the labor crew. He explained that I owed my new career to Charles Foster who gallantly went to bat for me. I told him I was grateful.
I was also given a Pocket Protector and a pair of small screwdrivers (one a philips screw driver). Charles explained that I would probably use these small screwdrivers more than any of the other tools. I also was given a small notebook and a pen. All of this went into my pocket protector. Which went into the vest pocket on my flannel shirt.
Our Pocket Protectors were freebies given to us by vendors so they would have advertisements on them like these
We went back down to the electric shop and Charles introduced me to Gene Roget again and Charles asked Gene if he would help me organize my tools and teach me some of the basics around being an electrician. Gene said that the first thing I needed to do was to lubricate my new tools. It just doesn’t do to have tools that are stiff. So, we worked on lubricating them and we even went down to the machine shop to get some abrasive paste that we worked into the tools to loosen them up. Gene took his side cutters and threw them up in the air and as they flew up, they rapidly opened and closed making a rattling sound. He caught them as they came down as if they were tied on his hand like a YoYo.
Wire Cutters similar to what I had
I worked the tools back and forth. Lubricating them and rubbing the abrasive paste in the joint. I had no coordination, so when I would try throwing my pliers in the air like Gene did, they would end up on the other end of the workbench, or across the room. So, I didn’t try it too often when others were around where I might injure someone. I thought. I’ll work on that more when I’m alone or just Gene is around. He had good reflexes and was able to quickly dodge my miss-thrown tools.
After Lunch Charles said that we had a job up at the coalyard that we needed to work on. He told me to grab my tool bucket and the multimeter from the cabinet. The electricians referred to it as the “Simpson”.
We had a couple of these Simpson Analog Multimeters in the shop
This was before each of us were issued our very own digital Fluke Mulimeter a few years later. I’m sure the old electricians are chuckling to remember that we used to use these old Multimeters. Charles explained to me that when you are checking voltage with the meter, that after you turn the dial to check voltage, always touch the two leads together to make sure the meter doesn’t move before touching the electric wires. This is done because if something happens that causes the meter to still be on “Resistance”, then when you check the voltage, the meter or the leads could explode possibly causing an injury. I had observed the electricians in the shop doing this back when I was a janitor, and now I knew why.
Charles explained that we needed to find out why the heater in the small pump room on the northwest corner of the dumper wasn’t running. So, we went to coalyard and found the space heater mounted along the wall. We tested it to make sure it wasn’t running. After checking the circuits with the multimeter on a panel on the wall, we found that we needed to replace a small fuse block because it had become corroded from all the coal dust and moisture.
I had seen electrical he-men go up to a panel and hold a screwdriver in their hand out at arms length and unscrew screws rapidly, one at a time. Bill Rivers had been doing that up on the precipitator roof when I was working with him while I was still on the Labor Crew. He could unscrew screws from a terminal block faster than I could unwrap Hershey Kisses.
So, when Charles told me to remove the fuse block from the panel, I thought this would be an easy task. I pulled out a screwdriver from my handy dandy tool bucket and with one hand holding the screwdriver, and the other hand steadying it by holding onto the stem of the screwdriver I moved toward the panel. Charles stopped me by saying something like: “Rule number one. Never use two hands. Especially when you are working on something hot.” Ok. I see.. If one hand is touching the metal screwdriver, and I come into contact with the screw which is electrified, then… um… yeah. Ok. I dropped one hand to my side and proceeded to remove the fuse block. That other hand remained at my side for the next 18 years when working on something hot (something is hot when it has the electricity turned on).
I explained above that I was pretty uncoordinated when it came to flipping my side cutters up into the air trying to act impressive like I knew what I was doing. Well. I couldn’t hold a screwdriver steady for the life of me. I tried to match up the head of the screwdriver with the slot in the screw, but I was pretty wobbly. It was kind of embarrassing. The truth had come out. This guy can’t even hold a screwdriver still. How is he ever going to become a real electrician?
A small fuse block like this.
Using all my concentration, I fumbled about and began working the screw out of the fuse block, when suddenly the screwdriver slipped slightly and Pow! Sparks flew. I had shorted the screwdriver between the screw and the hot post on the fuse block. There was a quick flash of light and a loud pop. Geez. The first time I’m working on something, what do I do? I blew it….. literally.
Well. Charles pointed out. The electricity is off now. Go ahead and change out the fuse block, then we will find out where the source of power is for it. So, I changed it out…. Feeling a little down that my new screwdriver now had a neat little notch on the blade where the electricity had melted off a corner of my screwdriver (I carried that notched screwdriver around for the next 10 years before I replaced it). We found the breaker that had been tripped in a DP Panel (which stands for Distribution Panel) in the Dumper Air Handler room and turned it back on. We checked the heater and it was working.
At the end of the day, when Bill Bennett came down to the shop to see how my first day went, Charles told him that I had jumped right into it and already had a notch in my screwdriver to prove it. Both Bill and Charles were good-natured about it. I filled out my timecard which told a short story about my first adventure as an electrician.
As I walked to the parking lot with Bill Rivers to go home, I was thinking that even though I had been full of nerves all day, this had to be one of the most exciting days of my life. I was actually one of the electricians now. I had the feeling that somehow something was going to happen and they were going to tell me that they made a mistake and that I would have to go back to the labor crew. That was a feeling that haunted me for about 3 months after moving to the electric shop.

Power Plant Manhole Mania
Originally posted February 1, 2013:
It is vitally important that a manhole cover be round. By just being square or even oval, it could mean death to some unsuspecting electrician. You see, only a perfectly round manhole cover will never be able to fall down into a manhole. No matter how hard you try, you just can’t fit a bigger circle through a smaller circle. An oval or square cover could fall through the hole when turned just right but not a round one. A typical cast iron manhole can weigh up to 500 pounds.
Here is a manhole cover turned upside down. Because of the way it is shaped, when you push the cover over the hole, it falls right into place.
Not long after becoming an electrician, and shortly after the Rivers and the Rose story that I mentioned last week (see the Post “Rivers and Rose in the Power Plant Palace“), we had a cable really go to ground between the main plant and the coalyard. The cable that went to ground was called a 500 MCM cable. What this means is that 500,000 circles of 1 mil (or one milli-inch) in diameter can be put in a circle that is 500 MCM in diameter. A typical 500 MCM cable is good for a 400 amp load at 6900 volts.
500 MCM cable. Over 2 inches in diameter.
For large industrial circuits, 3 phases of electricity are used instead of just one like you have in your house. With three phases of electricity, you have a constant amount of power being applied to the entire circuit at all times. With a one phase circuit, you have zero power 120 times every second. So with any “decent” power circuit, you have 3 phases of electricity.
When you add up the difference betweenvoltages of all three phases at one time, you always equal zero because you have the same amount of positive volts with negative volts at any given time. So, you will find that you always have a constant voltage between all three phases at any time.
The cable that went to ground was the coalyard station power cable. Not only were there three phases of power, but for each phase there were two 500 MCM cables. That means that this circuit was good for 800 amps of power at 6,900 volts. Giving you a capacity of 5.5 Megawatts (or 5 million, 500 thousand watts) of power. These cables were so big that a typical industrial Wire cable chart doesn’t even go this high:
500 MCM cable is also known as 5/0 cable (pronounced 5 aught). The 445 amps for the 4/0 cable are for only 50 volts. We had 6900 volts.
In a Coal-fired power plant, you have a redundant system for everything. So, the coalyard wasn’t completely in the dark. It had just swapped over to the redundant circuit. — This always amused me. In my English and Poetry classes in College I would have points taken off for being “redundant”, but in the power plant this was necessary to keep the plant running at all times.
As I said 15 years later, when I was training operators and electricians to be certified substation switchmen, “I know this is boring, but you have to learn it…” (but that is another story).
So, to make a rather boring lecture shorter, I will skip the part about how we had a hypot from the T&D (Transmission and Distribution) department brought in so big that it had to come in a van. They attached it to the cables to find where the short to ground was located. I’ll skip the part about how it was decided to replace the faulty cables going to the coalyard 1/2 mile away. I’ll also skip the part about how Charles Foster was able to finagle the use of Stanley Elmore’s precious blue Mitsubishi mini-tractor to try to pull the cables from one manhole to the next (the first time anyone outside the garage was able to operate his most beloved tractor…..).
A tractor just like this
Oh, and I’ll skip the part about how 1000 feet of this cable cost about $10,000 and we had six cable to replace for a cost of about $320,000 just for the cable… I’ll also skip the part about how this little tractor was too small to pull the cables through the manholes from manhole to manhole up to the coalyard, so we sent in for the big guns from the T&D department to use their equipment that pulled the cables through the manholes as easy as pulling the wool over Gene Day’s eyes while playing a joke on him. (Don’t get me wrong…. I know in his heart, Gene Day really appreciated a good joke. Gene Day is one of the best men I have ever been able to call “Friend” — which I would do shortly after playing a joke on him, after I returned to consciousness).
Anyway, after this episode was all over it was decided that something needed to be done about how all the manholes from the plant to the coalyard were always full of water. You see, the manholes were easily deeper than the lake level so water naturally leaked into them. Each of them had a pump in them that was supposed to keep them dry, but somewhere along the line, in the 5 years the plant had been in operation, each manhole pump had failed at one time or other… When pumping out the first manhole, it took days, because as you pumped out that first manhole, water would run from one manhole to the other as you actually ended up pumping out all the manholes down to the point where the cables went from one manhole to the other.
So, none other than the “newbie” was appointed as the keeper of the Manhole pumps. Yep. That would be me. So, for the next few months I spent almost all my times pumping out manholes and repairing all the pumps that had been submerged in water for years. This was my first real job.
This was my real introduction to becoming a real plant electrician (You can see how I really like using the word “real”). The most common job of an electrician was to take a motor that had failed or was scheduled to be overhauled and repair it and put it back in place to continue on it’s “tour of duty”. It’s amazing how you can take a motor that has failed, and you can “rebuild” it and put it back in operation. — This has come in handy at home as the cooling fan motor on the air conditioner unit on your house goes out every few years. I have yet to call an air conditioner man to my current house where I have lived for 11 1/2 years (now 16 years).
I remember that Charles Foster had told me that “paperwork” was very important when it came to motors. A history had to be kept. Certain steps had to be performed before, during and after repairing a motor. It had to be meggared properly (see the post from last week to learn more about meggars: Rivers and a Rose of the Power Plant Palace).
So, I asked Ben Davis if he could show me what I needed to do to fix a motor. His immediate indignant response was, “What? You don’t know how to fix a motor?” My response was, “No, I don’t know. Would you show me?” Ben, who up to that point had presented himself with displeasure at my presence in the shop, suddenly smiled and said, “Sure! Let me show you what you need to do!”
Ben showed me all the steps you go through to repair and “document” a motor repair in great detail. I was glad that I had found that Ben was just putting on a front of disgust at my presence in the Electric shop only to show me at the “proper” time that I had been “misjudging” him as being a grumpy person when he wasn’t really….
I had figured, before this time, that Ben really had a kind heart because I figured that if Diane Lucas and Andy Tubbs, who I both admired greatly considered Ben as a good friend, then he must really be a good guy underneath, even though he was keeping this hidden from me.
I knew the moment he smiled at my response when I told him I really didn’t know anything, that Ben had a kind heart. He couldn’t hide it any longer. If I had asked the same thing to OD McGaha, one of the other B Foremen in the shop, for instance, he would have told me to go to hell. But not Ben.
I have more to tell you about Ben, but I’ll save that for a later post. For now, I’ll just say that though Ben may not have known it during the time I spent as an electrician, he has always been close to my heart. I have always had Ben and his family in my daily prayers from the day that he smiled at me and explained to me how to repair a motor.
So, how does a lone newbie electrician pull a 500 pound lid off of a manhole by himself? Well. He uses a Manhole cover puller of course.
A Manhole cover puller
Ok. Our manhole cover puller wasn’t blue like this, but it had a similar shape. With a simple tool like this a 500 pound manhole cover could be popped out of the hole and dragged away. So, I used this tool as my one man crew (myself) went from manhole to manhole, where I pumped each out and lowered a ladder into each hole and disconnecting the drenched motor and brought it back to the shop where I dried it out (using the hot box in the shop that doubled as a heater for lunches), and repaired it and re-installed it.
We had all the manholes in the plant identified. I painted the numbers on each lid with orange paint. It was while I was working in the manholes 15 feet below ground that I appreciated the round manhole. I knew that as long as that manhole cover was round, it couldn’t accidentally be knocked into the hole only to crush me to death below.
Other things were of concern in the manholes where I worked… For instance, many of these holes had been underwater for at least a couple of years, and the entire manhole was covered with a kind of slime. there were also high voltage cables that had splices in some of the manholes, and I remember Gene Roget telling me that he had seen sparks flying off of some of them when they were hypoting the cables looking for the ground. The dank smell of the manholes made you think that there were probably some kind of “swamp gases” in there.
Nevertheless, when I grew weary of dragging the heavy shellacked wooden ladder from hole to hole, I devised a way to climb down into the manholes using the drain pipe from the motor. This was before OSHA had implemented all the confined spaces rules in 1994 that would have prevented me from entering a manhole alone. I was improvising and taking a risk of falling and hurting myself each time I entered a manhole.
I ran into one of the reasons for not leaving a person in a manhole alone one time when I was working in a manhole near the intake house and another crew drove up and parked their truck near the hole I was working in. I remember that while I was working there, I suddenly became nauseous. Not sure why, I climbed out of the hole.
The truck that had been left idling nearby had been emitting toxic fumes that had looked for the lowest place they could settle, and that happened to be in the manhole where I was working. After that, I always kept an ear out for any motor vehicles nearby when I was in a manhole.
Ten years later, in 1994, OHSA added some new laws to the books that made it mandatory to have a “hole watch” stand outside a hole watching you while you worked in a manhole. You even had to have a safety harness tied to a safety hoist so that if you passed out while in a manhole the hole watch could pull you out without having to enter the hole.
This is a special hoist designed to lift a person out of a confined space without seriously injuring someone that is caught on obstacles.
Needless to say. I got my feet wet as an electrician popping in and out of manholes like the gopher in the arcade that you try to bop on the head.
One interesting story that happened during this time happened when Blake Tucker, who had been a summer help with me in the garage, and then later became a summer help in the electric shop, was sitting with me while we were going to fix a pump in manhole 215 (I believe this is the number of the manhole next to the intake where the fly ash pipes go over the intake).
The hole was full of water, and the pump had naturally tripped the breaker….. For some reason I decided to go into the intake switchgear and reset the 120 volt breaker to the pump in the Distribution Panel. When I did. I returned to the hole where Blake was waiting for me. I reached down into the hole with my foot and I kicked the drain pipe that rose from the pump and made a 90 degree turn up close to the entrance.
When I kicked the pipe, the motor actually began running. We could see it 15 feet below us in the clear water running. It was an open face motor, meaning that it wasn’t sealed and made to be a submersible pump, yet it was running under water. A year later we decided that it made more sense to replace all the open motors with submersible pumps.

Blake Tucker and I watched for 1/2 hour as the pump sucked out the water from the manhole. When the level of the water reached the top of the motor, the outboard fan that had been slowly rotating all of the sudden kicked into high gear and we could see that the pump had been running at full speed all along.
This fascinated me. I figured the water must have been pure enough not to be too conductive (pure water is a natural insulator…. oddly enough). We could easily see this pump through 15 feet of water, so it must have been pretty clean. That was the only time I have ever seen an open motor happily running submersed in water… It is not something you see every day….. for instance…. It is not every day that you see a janitor with a Psychology major acting like an electrician sitting beside a manhole staring down into the darkness in a power plant either. But there you are…
Power Plant Men 
I worked with Ed on the Precipitator control replacement project (84 controls X 2) in 2006 I think. He was getting ready to retire at the time. He was a good engineer and a tough customer. I was working for the control supplier and those 168 controls were the first installation of a brand new control design. I had lead the design team for the controls and this was the culmination of our work. I spend more days and nights than I can remember going up and down the aisles of controls loading software fixes into the processors! Anyway, great people at the plant and great memories… including a rapper control cabinet that took the express route to the ground elevation from the precip roof! (ouch, it really is the sudden stop that gets you!)
Thanks for the comment John! It’s good to hear about improvements to the Precipitator and the control rooms I used to call home. I spend many weekends walking back and forth through those control rooms.
OMG – The very thought of a group staying in the boiler when the dynamite went off! Thank goodness THAT didn’t happen. I felt the tension just reading that bit. I’m glad Ed came out of it all right.
